Description

Before safeguard casing

Technical field

The utility model relates to the LED technical field, relates more specifically to a kind of front casing of safeguarding for loading LED display.

Background technology

Along with the extensive use to LED display of various key activities and place, LED display has been penetrated into each corner of people's daily life.The LED display casing that generally uses is at present normally offered the back door at rear box, and what adopt when safeguarding is rear maintenance mode, and this need to guarantee the enough spaces of reservation, display screen back when mounted.Yet in a lot of practical application, LED display all is to install by wall, can't provide enough back spaces to carry out rear attended operation, brings very large difficulty to later maintenance work.

Given this, be necessary to provide a kind of casing of front maintenance that carries out to address the aforementioned drawbacks.

The utility model content

The purpose of this utility model provides a kind of front casing of safeguarding conveniently to be loaded on the maintenance of the LED display in the casing.

To achieve these goals, the technical solution adopted in the utility model is: provide and safeguard casing before a kind of, it comprises front casing, rear box and at least one supporting mechanism, described front Box Cover is combined on the described rear box and can overturns with respect to described rear box, described supporting mechanism comprises and is arranged on the support bar on the described rear box and is arranged on retaining structure on the described front casing, described support bar comprises a stiff end and a round end, described stiff end is articulated on the described rear box, and described round end can and be limited in the retaining structure of described front casing and props up described front casing with respect to the rotation of described rear box.

Its further technical scheme is: described supporting mechanism comprises that also be used to the accepting groove of accommodating described support bar, described accepting groove is opened in covering on the face of described rear box.

Its further technical scheme is: be provided with a card-bit part for fixing described round end in the described accepting groove.

Its further technical scheme is: described card-bit part is Ω type shell fragment.

Its further technical scheme is: described retaining structure is a groove, and described groove is opened in covering on the face of described front casing.

Its further technical scheme is: safeguard before described that the right and left is provided with two described supporting mechanisms symmetrically on the casing.

Compared with prior art, casing can be fixed on a certain anglec of rotation with respect to the rear box upset and by support bar before safeguarding in the casing before the utility model, thereby can in small space, finish the front maintenance to casing, solved by space problem and caused restriction to the display screen installability, the specific (special) requirements of some specific installation environment be can satisfy, easy maintenance, purpose efficiently reached.

By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.

Description of drawings

Fig. 1 safeguards before the utility model that casing one embodiment is in the stereogram of maintenance state.

Fig. 2 is the front left view of safeguarding casing shown in Figure 1.

Fig. 3 is the front schematic diagram of safeguarding under the casing normal operating condition shown in Figure 1.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the embodiment is clearly and completely described, assembly label identical in the accompanying drawing represents identical assembly.Obviously, below only be the utility model part embodiment with the embodiment that describes, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

Fig. 1 to Fig. 3 has showed an embodiment of the present utility model.Referring to figs. 1 through Fig. 3, the front casing 100 of safeguarding of present embodiment comprises front casing 110, rear box 120 and two supporting mechanisms 130, wherein, the top of described front casing 110 and rear box 120 is articulated, and two described supporting mechanisms 130 are arranged on the both sides of casing symmetrically.When leading dimension protecting box body 100 is in normal operating condition, front casing 110 covers together with rear box 120, and when needing to be serviced, front casing 110 can be overturn with respect to rear box 120 and by supporting mechanism 130 front casing 110 is positioned at the carrying out that a certain position of rotation is sentenced the work of maintaining easily.Above-mentioned two supporting mechanisms 130 have identical structure, and the below illustrates its concrete structure and operation principle as an example of one of them example.

In the present embodiment, described supporting mechanism 130 comprises the retaining structure 134 on the face of covering that covers accepting groove 131 on the face, is arranged on support bar 132 and the card-bit part 133 in the described accepting groove 131 and is arranged on front casing 110 that is opened in rear box 120, particularly, described support bar 132 comprises stiff end and round end, in the present embodiment, described stiff end places the downside of accepting groove 131, and be articulated in the accepting groove 131 by pin, described round end then places the upside of accepting groove 131, and removably is fixed in the accepting groove 131 by card-bit part 133.Wherein, described card-bit part 133 adopts Ω type shell fragment to realize making things convenient for snapping in and taking out of round end, and described retaining structure 134 is that a rectangular recess carries out screens with convenient round end to support bar 132.

With reference to Fig. 2, when the LED display in needs are opposite to casing is safeguarded, only need with casing 110 before the upset of the counter clockwise direction shown in the arrow A, in the retaining structure 134 of round end with the rotation of the counter clockwise direction shown in the arrow B and the front casing 110 of insertion with support bar 132, then front casing 110 can be positioned at position shown in Figure 2 in order to carry out the maintenance of box house again.

As mentioned above, casing can be fixed on a certain anglec of rotation with respect to the rear box upset and by support bar before safeguarding in the casing before the utility model, thereby can in small space, finish the front maintenance to casing, solved by space problem and caused restriction to the display screen installability, the specific (special) requirements of some specific installation environment be can satisfy, easy maintenance, purpose efficiently reached.

Need to prove, safeguard before the utility model that the quantity of the supporting mechanism 130 in the casing and structure are not limited to above-mentioned situation.Casing in other embodiments, a supporting mechanism can be set separately, as long as then could before the support force of this supporting mechanism was enough to firm support; And in other embodiments, support bar 132 and corresponding accepting groove 131 structures can be arranged on the front casing 110, and retaining structure 134 is arranged on the rear box 120, supporting construction also can be arranged on the side of casing, and the quantity of retaining structure 134 is not limited to one, can arrange according to concrete needs a plurality of so that front casing 110 is positioned on the different flip angles.

Abovely in conjunction with most preferred embodiment the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contains various modification, equivalent combinations of carrying out according to essence of the present utility model.
