The adjusting device provided by the embodiment of the invention is described in further detail below.
With continued reference to fig. 3, the unidirectional rotation assembly in an embodiment of the present invention includes a unidirectional coupling gear 30 and an internal gear 31 engaged with the unidirectional coupling gear 30. When the unidirectional coupling gear 30 is meshed with the internal gear 31 and the clutch shaft 21 stretches into the tooth groove of the locking tooth, the unidirectional rotation assembly can limit the rotation direction of the gear 10, and under the action of the unidirectional rotation assembly, the gear 10 can only rotate in one direction.
The unidirectional coupling gear 30 is provided with a receiving hole 32. The unidirectional coupling gear 30 is provided with a stepped hole 33 penetrating through the gear wall of the unidirectional coupling gear 30, the axis of the stepped hole is perpendicular to the wheel shaft of the unidirectional coupling gear 30, and the clutch shaft 21 is positioned in the stepped hole 33. The clutch shaft 21 can reciprocate linearly along the hole axis of the stepped hole 33. For example, the clutch shaft 21 extends into the receiving hole 32 along the hole axis of the stepped hole 33 or comes out along the hole axis of the stepped hole 33.
Referring to fig. 4, the adjusting portion includes a first contact portion 41 and a second contact portion 42, and the first contact portion 41 and the second contact portion 42 are not equidistant from the axis of the adjusting wheel 40 and are connected by a rounded transition portion 43.
Fig. 5 is a schematic view of the use state of the adjusting device according to the embodiment of the present invention, see fig. 5.
When the regulating wheel 40 is at the first position, the first contact portion 41 is connected with the clutch shaft 21 and applies a pressing force along the axial direction of the clutch shaft 21, so that the clutch shaft 21 extends into the accommodating hole 32 from the stepped hole 33 and into the tooth groove of the locking tooth of the locking wheel 11, the elastic body 22 is deformed, the regulating wheel 40 is connected with the gear 10 through the clutch shaft 21, and the gear 10 is driven to rotate unidirectionally through rotating the regulating wheel 40.
When the regulating wheel 40 is switched from the first position to the second position, the clutch shaft 21 is separated from the tooth groove of the locking wheel 11 and connected with the second contact part 42 under the action of the restoring force of the elastic body 22 in the process from the first contact part 41 and the smooth transition part 43 to the second contact part 42, the regulating wheel 40 is separated from the gear 10, and the gear 10 can rotate bidirectionally.
Referring to fig. 6, in the embodiment of the present invention, the clutch shaft 21 includes three segments, and the first, second and third segments 23, 24 and 25 gradually decrease in diameter size. The elastic body 22 is a spring, the spring is sleeved on the second section 24, one end of the spring is contacted with the first section 23, and the other end of the spring is contacted with the step surface of the step hole 33.
The spring can be restrained in the stepped hole 33 by the first section 23 and the stepped surface of the stepped hole 33, and a downward pressure is applied to the spring by the first section 23 when the regulating wheel 40 is connected to the clutch shaft 21 by the first contact portion 41, and an upward pressure is applied to the clutch shaft 21 by the spring by the first section 23 when the regulating wheel 40 is connected to the clutch shaft 21 by the second contact portion 42.
With continued reference to fig. 3, in the embodiment of the present invention, the unidirectional coupling gear 30 includes a first supporting arm 34 and a second supporting arm 35 having elasticity, one end of the first supporting arm 34 is connected to the cylindrical surface of the unidirectional coupling gear 30, one end of the second supporting arm 35 is connected to the other end of the first supporting arm 34, and the other end of the second supporting arm 35 is provided with a coupling tooth 36;
the one-way coupling gear 30 is meshed with the internal gear 31 through the coupling teeth 36.
Specifically, when the unidirectional coupling gear 30 rotates clockwise, the second support arm 35 deforms so that the coupling teeth 36 are separated from the internal gear 31 when the peaks of the coupling teeth 36 pass the peaks of the internal gear 31, and the second support arm 35 returns to the original state so that the coupling teeth 36 mesh with the internal gear 31 when the peaks of the coupling teeth 36 pass the valleys of the internal gear 31. When the unidirectional coupling gear 30 rotates in the opposite direction, the coupling teeth 36 abut against the internal gear 31, so that the second support arm 35 cannot be deformed, and the unidirectional coupling gear 30 cannot rotate in the opposite direction. Therefore, when the one-way coupling gear 30 is connected to the gear 10 through the clutch shaft 21, the one-way coupling gear 30 restricts the gear 10 from rotating in only one direction.
In addition, the coupling teeth 36 of the unidirectional coupling gear 30 may be one or more. When there are a plurality of coupling teeth 36, the plurality of coupling teeth 36 are uniformly distributed along the center circumference of the unidirectional coupling gear 30. The plurality of coupling teeth 36 are uniformly stressed and also provide a better locking effect.
Since the locking wheel 11 of the gear 10 is located in the accommodation hole 32 of the unidirectional coupling gear 30, friction is easily generated between the gear 10 and the unidirectional coupling gear 30 when the gear 10 rotates, and damage is easily generated to the locking wheel 11 and the accommodation hole 32 for a long time.
In order to reduce damage caused by friction, referring to fig. 1 and 8, in the embodiment of the present invention, a bearing groove is disposed on a side wall of an opening of the accommodating hole 32 near one side of the gear 10, and a first washer 13 is sleeved on one end of the locking wheel 11 far from the adjusting wheel 40. Wherein the first gasket 13 is in contact with the bearing groove.
A bearing boss is provided on the side wall of the opening of the receiving hole 32 near one side of the regulating wheel 40. The locking wheel 11 is provided with a first gasket 14, a second gasket 15 and a second gasket 16 which are sleeved in sequence at one end close to the adjusting wheel 40. Wherein the second gasket 16 is in contact with the bearing boss.
It should be noted that the positions of the bearing groove and the bearing boss may be interchanged, that is, the bearing boss or the bearing groove is disposed on the side wall of the opening of the accommodating hole 32 near the side of the gear 10, and the bearing groove or the bearing boss is disposed on the side wall of the opening of the accommodating hole 32 near the side of the adjusting wheel 40. Of course, the first gasket 13 and the second gasket 15 may also be interchanged.
With continued reference to fig. 1, in order to make the structure of the adjusting device more compact and more beautiful, and make the components of the adjusting device integrated, in an embodiment of the present invention, the adjusting device further includes: the first housing 50 and the second housing 51.
The first housing 50 is connected to the second housing 51 and encloses a mounting chamber. The gear 10 is disposed within the mounting cavity. The clutch assembly 20, the unidirectional rotating assembly and the adjustment wheel 40 are disposed outside the mounting cavity.
Referring to fig. 1, 4 and 7, the first housing 50 is provided with a first connection hole 52, and the second housing 51 is provided with a second connection hole 53. The adjusting rotating wheel is provided with a connecting rod 44, one end of the connecting rod 44 is provided with a clamping part 45, and the connecting rod 44 sequentially penetrates through the unidirectional rotating assembly, the second connecting hole 53, the gear 10 and the first connecting hole 52 and is clamped with the first connecting hole 52 through the clamping part 45.
Example 2
With continued reference to fig. 1, accordingly, an embodiment of the present invention also provides an adjustable strap including strap 60 and an adjustment device as in embodiment 1.
The strap 60 is connected at both ends to the gear 10. When the adjusting wheel 40 is at the first position, the adjusting wheel 40 applies a downward pressure along the axial direction of the clutch shaft 21 through the adjusting part, so that the clutch shaft 21 extends into the accommodating hole and into the tooth slot of the locking tooth, and the gear 10 is driven to rotate unidirectionally by rotating the adjusting wheel 40 so as to tighten the binding belt 60;
when the regulating wheel 40 is in the second position, the clutch shaft 21 is disengaged from the tooth grooves of the locking teeth by the restoring force of the elastic body 22, and the gear 10 can be rotated in both directions to tighten or loosen the binding band 60.
As for the manner in which the strap 60 is connected to the gear 10, one possible manner is that, when strap teeth 12 are provided on the outer periphery of the gear 10, racks 61 are provided on both ends of the strap 60, as seen in fig. 1. Two racks 61 are respectively engaged and connected to opposite sides of the gear 10, so that the two straps 60 are moved in opposite directions when the gear 10 rotates. Specifically, when both racks 61 are moved toward each other, the tightening adjustment is performed on the strap 60, and when both racks 61 are moved away from each other, the loosening adjustment is performed on the strap 60.
