Cables are a generic term for items such as optical cables and electric cables. The cable has a plurality of purposes, is mainly used for controlling multiple functions such as installation, connection equipment, power transmission and the like, and is a common and indispensable thing in daily life. In the use process of the cable, the cable is often influenced by various external factors, such as treading, extruding, pulling, collision and the like, so that the cable is damaged, and the service life of the cable is influenced. Thus, the cable needs to be protected during use.

In the related art, the process of installing and detaching the cable protection tube is troublesome, a specific tool may be needed, and the time spent is long, so that a cable protection tube with low installation and detachment difficulty and simpler and more convenient use is needed.

Based on this, the present application provides a protective tube for a cable.

Fig. 1 is a schematic perspective view of a cable protection tube according to an embodiment of the present disclosure. The cable protection tube comprises a first splice plate 1, a fixing component 5 and a connecting component 6.

As shown in fig. 1, the number of first splice plates 1 is plural, and the plural first splice plates 1 can be sequentially connected and define a first lumen 001. After the first splice plates 1 are sequentially connected, a plurality of splice joints 10 can be formed, one of the splice joints 10 is a first splice joint 11, and the rest is a second splice joint 12. Wherein the number of first splice plates 1 is the same as the number of splice joints 10.

Illustratively, referring to fig. 1, there may be two first splice plates 1, and the two first splice plates 1 may be connected in sequence and define a first lumen 001. Two first splice plates 1 are sequentially connected to form two splice joints 10. One of the two splice seams 10 is a first splice seam 11 and the other is a second splice seam 12.

As shown in fig. 2, fig. 2 is a schematic structural diagram of a plurality of first splice plates sequentially connected according to an embodiment of the application. The number of the first splice plates 1 may be three, and the three first splice plates 1 may be sequentially connected and define a first lumen 001. The three first splice plates 1 are sequentially connected to form three splice joints 10. One of the three splice seams 10 is a first splice seam 11 and the other two splice seams are second splice seams 12.

It is understood that the number of the first splice plates 1 may be four or more. The number of first splice plates 1 may be specifically set according to the size of the cable and the first lumen 001. For example, in the case where the size of the first lumen 001 is less than or equal to the first preset value, the number of the first splice plates 1 may be two; in the case where the size of the first lumen 001 is greater than the first preset value and less than or equal to the second preset value, the number of the first splice plates 1 may be three.

Illustratively, the first splice plate 1 may be an arcuate plate, in which case the first lumen 001 may be circular or elliptical in cross-section. For example, referring to fig. 1, the first splice plate 1 may be a circular arc plate, in which case the cross section of the first lumen 001 is circular, i.e., the first lumen 001 is a cylindrical cavity. For example, the first splice plate 1 may be an elliptical arc plate, in which case the cross-section of the first lumen 001 is elliptical, i.e., the first lumen 001 is an elliptical cylindrical cavity.

As shown in fig. 3, fig. 3 is a second schematic structural diagram of a plurality of first splice plates sequentially connected according to the application embodiment. The first splice plate 1 may be a flat plate, in which case the cross-section of the first lumen 001 may be polygonal. For example, the first splice plate 1 may be three and flat, and in this case, the cross section of the first lumen 001 may be triangular. For example, the first splice plate 1 may be four and flat, and in this case, the cross section of the first lumen 001 may be quadrangular.

It is understood that the shape of the first splice plate 1 and the shape of the first lumen 001 may be specifically set according to the shape of the cable and the shape of the installation position and installation space of the protective tube for the cable.

For ease of understanding, the following definitions are made for the first splice plate 1: the two first splice plates 1 on both sides of the first splice joint 11 are a first splice plate a and a first splice plate b, respectively, and the two first splice plates 1 on both sides of the second splice joint 12 are a first splice plate c and a first splice plate d, respectively.

It can be understood that, in the protection tube for a cable provided in the embodiment of the present application, the first splice a and the first splice c may be the same first splice 1, and the first splice b and the first splice d may be the same first splice 1.

For example, when there are two first splice plates 1, the first splice plates a and c are the same first splice plate 1, and the first splice plates b and d are the same first splice plate 1.

For example, when the number of the first splice plates 1 is three, the first splice plates a and c on one side of the first and second splice lines 12 are the same first splice plate 1, the first splice plates d on the other side of the first and second splice lines 12 and c on one side of the second and second splice lines 12 are the same first splice plate 1, and the first splice plates b and d on the other side of the second and second splice lines 12 are the same first splice plate 1.

For example, in the case where there are four first splice plates 1, the first splice plate a is identical to the first splice plate c on one side of the first second splice joint 12 by the first splice plate 1, the first splice plate d on the other side of the first second splice joint 12 is identical to the first splice plate c on one side of the second splice joint 12 by the first splice plate 1, the first splice plate d on the other side of the second splice joint 12 is identical to the first splice plate c on the one side of the third second splice joint 12 by the first splice plate 1, and the first splice plate b is identical to the first splice plate d on the other side of the third second splice joint 12 by the first splice plate 1.

Fig. 4 is a schematic overall perspective view of a cable protection tube connection assembly according to an embodiment of the present disclosure. The connecting assembly 6 includes a first connecting member 61 and a second connecting member 62, which are connected to the two first splice plates 1 on both sides of the second splice joint 12, respectively. That is, the first connecting piece 61 is connected to one of the two first splice plates 1 on both sides of the second splice joint 12; the second connecting piece 62 is connected to the other of the two first splice plates 1 on both sides of the second splice joint 12.

With continued reference to fig. 4, the first and second links 61 and 62 are rotationally coupled, and the axis of rotation between the first and second links 61 and 62 extends along the axial direction of the first lumen 001 (e.g., the X-direction in fig. 4). In this way, the two first splice plates 1 on both sides of the second splice joint 12 can be rotated relatively, that is, the adjacent first splice plates c and d can be rotated relatively, so that the plurality of first splice plates 1 can enclose the first lumen 001, and the plurality of first splice plates 1 can be unfolded to open the first lumen 001.

Referring to fig. 1, the fixing assembly 5 includes a first fixing piece 51 and a second fixing piece 52, which are respectively connected to two first splice plates 1 at both sides of a first splice joint 11. That is, the first fixing piece 51 is connected to one of the two first splice plates 1 on both sides of the first splice joint 11; the second fixing piece 52 is connected to the other of the two first splice plates 1 on both sides of the first splice joint 11.

Further, referring to fig. 1, the first fixing member 51 and the second fixing member 52 are detachably connected, that is, the first fixing member 51 and the second fixing member 52 may be connected or disconnected. In the case where the plurality of first splice plates 1 enclose the first lumen 001, the first fixing member 51 and the second fixing member 52 may be connected together, and the first lumen 001 may be stabilized in a closed state. Of course, the first fixing member 51 and the second fixing member 52 may be disconnected, and the plurality of first splice plates 1 may be unfolded to open the first lumen 001.

The cable protection tube provided by the embodiment of the application can be sequentially connected by using the plurality of first splice plates 1 and define the first tube cavity 001. When all the first splice plates 1 are connected in sequence, the first splice plates 1 enclose a first lumen 001, and the first lumen 001 is in a closed state. Also, the first fixing piece 51 and the second fixing piece 52 may be connected together, thereby locking the two first splice plates 1 on both sides of the first splice joint 11, so that the first lumen 001 may be stabilized in a closed state.

In addition, the first fixing member 51 and the second fixing member 52 may be disconnected, and the first connecting member 61 and the second connecting member 62 of the connecting assembly 6 may rotate relatively, so as to synchronously drive the two first splice plates 1 at two sides of the second splice joint 12 to rotate, so that the first splice plates 1 at two sides of the first splice joint 11 may be separated. In this way, the first lumen 001 in the closed state may be opened outward from the first splice joint 11. Of course, the cable protection tube provided in the embodiment of the present application may also allow the first lumen 001 that is not closed to be re-closed by the rotation of the first connector 61 and the second connector 62.

From the above, the cable protection tube provided by the application can be opened or closed through the rotation of the first connecting piece 61 and the second connecting piece 62, and can be locked in the closed state through the fixing component 5, so that the steps of repeatedly disassembling and installing the anchor ear and the ear plate are omitted, and the cable protection tube has the advantages of convenience in assembly and disassembly.

As shown in fig. 5, fig. 5 is a schematic perspective view of a cable protection tube according to an embodiment of the present application, where the cable protection tube provided in the present application further includes a plurality of second splice plates 2, and the plurality of second splice plates 2 are all located in the first lumen. The number of the first splice plates 1 is the same as the number of the second splice plates 2, one second splice plate 2 is connected with one first splice plate 1, and the second splice plates 2 can be sequentially connected and define a second lumen 002.

It will be appreciated that one second splice plate 2 corresponds to one first splice plate 1, and that a plurality of first splice plates 1 are connected in sequence and define a first lumen 001 while a plurality of second splice plates 2 are connected in sequence and define a second lumen 002.

Wherein, second lumen 002 is located in first lumen 001, and the cable that needs protection can be placed in this second lumen 002 by operating personnel, and the wall of first lumen 001 and the wall of second lumen 002 all can protect the cable. Therefore, the cable protection tube can achieve a better protection effect on the cable.

For example, when the cable protection tube provided by the application receives external pressure, and the external pressure is less than a preset value, the external pressure is in the bearing range of the first splice plate 1, and the first splice plate 1 completely bears the external pressure, so as to provide protection for the whole first lumen 001, the second lumen 002 and the cable. When the external pressure that the cable that this application provided receives is greater than the default, the external pressure surpasses first splice plate 1's bearing range, and first splice plate 1 bears partly external pressure, and second splice plate 2 can bear another part external pressure, provides the protection to the cable of second lumen 002 and inside.

Therefore, the protection tube for the cable can provide double protection for the cable, and the cable has better protection effect.

Illustratively, referring to fig. 5, there may be two second splice plates 2, and the two second splice plates 2 may be connected in sequence and define a second lumen 002. The two second splice plates 2 are sequentially connected to form two splice joints.

It is understood that the number of the second splice plates 2 may be three or more, and furthermore, the first splice plates 2 may be arc-shaped plates, flat plates, or other shapes. The number and shape of the second splice plates 2 will not be described in detail here, and reference is made specifically to the description of the first splice plates 1.

In some embodiments, with continued reference to fig. 5, the protective tube for cables provided herein further includes a plurality of elastic connectors 4, with one first splice plate 1 and one second splice plate 2 being connected by at least one elastic connector 4. For example, a first splice plate 1 and a second splice plate 2 may be connected by an elastic connection 4, or by two elastic connection 4. Of course, a first splice plate 1 and a second splice plate 2 may also be connected by three or more elastic connectors 4.

It will be appreciated that the elastic connection member 4 is supported between the first splice plate 1 and the second splice plate 2, and the size of the elastic connection member 4 can be adjusted according to the shape and the size of the first splice plate 1 and the second splice plate 2, so that the plurality of first splice plates 1 are sequentially connected to define the first lumen 001, and the plurality of second splice plates 2 are sequentially connected to define the second lumen 002.

In addition, the elastic connecting piece 4 has elasticity, can play buffering and damping effects, and can offset a part of pressure transmitted to the second splice plate 2 by the first splice plate 1, so that the pressure born by the second splice plate 2 can be reduced, and the protection effect on cables can be improved.

In some embodiments, referring to fig. 5, the elastic connecting member 4 may be an integrally formed elastic member, and two ends of the elastic connecting member 4 are connected to the first splice plate 1 and the second splice plate 2, respectively. In this way, the elastic connecting piece 4 has simple structure and convenient installation

It should be noted that the elastic connection member 4 may be a rubber column, and the material of the rubber column is easy to obtain and is convenient to connect with the first splice plate 1 and the second splice plate 2. The elastic connection 4 may also be a spring, but may of course also be other elastic elements, which are not specifically limited herein.

In other embodiments, as shown in fig. 6, fig. 6 is a schematic structural diagram of connection between an elastic connecting member and a first splice plate and a second splice plate provided in the embodiments of the present application, the elastic connecting member 4 may be an elastic assembly formed by sequentially connecting a plurality of components, where at least one of the plurality of components is an elastic member, and two components located at edges of the elastic connecting member 4 are respectively connected to the first splice plate 1 and the second splice plate 2.

It will be appreciated that the number of parts in the resilient connecting element 4 may be two or more, and that two adjacent parts may be fixedly connected or may slide relative to each other.

Illustratively, referring to fig. 6, the elastic connection 4 may comprise two parts, part 41 and part 42, respectively, at least one of part 41 and part 42 being an elastic member, part 41 being connected to the first splice plate 1, part 42 being connected to the second splice plate 2.

The elastic element in the elastic connecting element 4 has elasticity, can play a role in buffering and damping, and can offset part of pressure transmitted to the second splice plate 2 by the first splice plate 1, so that the pressure born by the second splice plate 2 can be reduced, and the protection effect on cables can be improved.

Illustratively, the members 41 and 42 are capable of relative sliding movement, the member 42 having a cavity, and one end of the member 41 extending into the cavity of the member 42. When the member 41 slides toward the member 42, air in the cavity of the member 42 is compressed and generates an elastic force that prevents the member 41 from continuing to slide, thereby providing a cushioning and damping effect. Therefore, the elastic connection member 4 can cancel a part of the pressure transmitted to the second splice plate 2 by the first splice plate 1, so that the pressure born by the second splice plate 2 can be reduced, which is advantageous for improving the protection effect on the cable.

Of course, the elastic connection member 4 may have other structures that can play a role of buffering and damping, which is not specifically limited herein.

In some embodiments, with continued reference to fig. 5, the cable protection tube provided in the embodiments of the present application further includes a plurality of flexible boards 3, where the plurality of flexible boards 3 are located in the second lumen 002, and one flexible board 3 is connected to one second splice plate 2 and is attached to an inner side surface of one second splice plate 2.

It will be appreciated that the flexible plate 3 is closely attached to the inner wall of the second splice plate 2, and the flexible plate 3 itself has a buffering and damping effect, so that part of the pressure transmitted by the second splice plate 2 can be counteracted, and the pressure in the second lumen 002 can be effectively reduced. In addition, the flexible board 3 can contact the cable in the second lumen 002, and has a buffering effect when the cable moves or shakes, so as to provide protection for the cable.

Wherein, the flexible board 3 can be a sponge board, and the sponge board has low cost and convenient material acquisition, and is beneficial to production and processing. Of course, the flexible board 3 may also be a nylon board, a rubber board, or other flexible materials with a cushioning and damping effect, which are not particularly limited herein.

Based on above, when the cable protection tube that this application provided receives ambient pressure, first splice plate 1, elastic connection spare 4, second splice plate 2, flexible sheet 3 all can bear ambient pressure, and elastic connection spare 4 and flexible sheet 3 have buffering, damped effect, consequently, the cable protection tube that this application provided can carry out multiple protection to the cable, and then can reduce the risk that the cable damaged, improves the life of cable.

In some embodiments, as shown in fig. 7, fig. 7 is an enlarged schematic view of structure a in fig. 1. The fixing assembly 5 further includes a fixing plate 53 and a first latch 54. The fixing plate 53 is connected to the first fixing member 51, a first insertion hole (not shown) for the first latch 54 to be engaged is provided in the fixing member 52, and a second insertion hole (not shown) for the first insertion hole to be engaged is provided in the fixing plate 53.

When the cable protection tube is closed, the first plug pin 54 can be inserted into the first insertion hole and the second insertion hole, so that the fixing plate 53 and the second fixing piece 52 are connected together, and the two first splice plates 1 on two sides of the first splice joint 11 can be locked, so that the first tube cavity 001 (see fig. 5) can be stabilized in a closed state.
