Description

Technical Field

[0001] The utility model relates to the technical field of charging fixing devices, and more specifically, the utility model relates to an anti - detachment structure for walkie - talkie charging. Background Technique

[0002] A walkie - talkie is a two - way mobile communication tool. It can achieve short - distance voice communication without network coverage. As a convenient communication tool for message transmission through radio signals, walkie - talkies have the characteristics of simple operation, easy to carry, and reliable communication, and are widely used in industries such as police, fire protection, security, logistics, and construction.

[0003] After retrieval, in the charging base with the publication number CN202020122277.2, it is proposed that due to the different positions of the charging ends of the walkie - talkie and the battery, the two charging bases have different structures, resulting in the problem that the two charging bases cannot be used interchangeably. And the above - mentioned problem is solved by setting a base, a first support, and a second support.

[0004] However, in the above - mentioned design, there are still problems that the size of the charging slot in the charging base is slightly larger than the size of the walkie - talkie, and the walkie - talkie lacks limitation and fixation during the charging process. This makes the walkie - talkie easy to fall off the charging base due to external vibration and the movement of the charging base. Therefore, it is necessary to design an anti - detachment structure to ensure that the walkie - talkie will not easily fall off the charging base. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an anti - detachment structure for walkie - talkie charging, which has the advantage of preventing the walkie - talkie from falling off.

[0006] To achieve the above - mentioned purpose, the utility model provides the following technical solution: an anti - detachment structure for walkie - talkie charging, including a walkie - talkie. The outer surfaces on the left and right sides of the walkie - talkie are both movably connected with clamping plates. The number of the clamping plates is two. The rear sides of the outer surfaces of the two clamping plates are both movably connected with hollow boxes. The upper and lower sides of the outer surfaces of the two clamping plates are both fixedly connected with limiting plates located inside the hollow boxes. The outer surface of the limiting plate is movably connected with the inner surface of the hollow box. The outer surface of the limiting plate is fixedly connected with a first spring located inside the hollow box. The other end of the first spring is fixedly connected with the inner surface of the hollow box. The middle part of the inner surface of the hollow box is movably connected with a cam. The outer surface of the cam is movably connected with the limiting plate. The inner surface of the cam is fixedly sleeved with a round shaft. The rear end of the round shaft penetrates through the hollow box and extends to the outside of the hollow box and is fixedly connected with a rotating handle.

[0007] As a preferred technical solution of the present utility model, a charging base is movably connected to the lower surface of the walkie-talkie. An installation plate is fixedly installed on the rear surface of the charging base, and the upper surface of the installation plate is fixedly connected to the lower surface of the hollow box.

[0008] As a preferred technical solution of the present utility model, a hinge rod is fixedly connected to the lower surface of the hollow box. The bottom end of the hinge rod penetrates through the installation plate and extends into the interior of the installation plate. The outer surface of the hinge rod is movably connected to the inner surface of the installation plate, and a limiting strip is fixedly connected to the bottom of the inner surface of the installation plate.

[0009] As a preferred technical solution of the present utility model, a moving block is movably connected to the inner surface of the limiting strip. The lower surface of the moving block is movably connected to the inner surface of the installation plate. The top end of the moving block is hinged to a connecting rod, and the other end of the connecting rod is hinged to the bottom end of the hinge rod.

[0010] As a preferred technical solution of the present utility model, a threaded rod is movably sleeved on the left surface of the installation plate. The right end of the threaded rod sequentially penetrates through the installation plate and the moving block and extends to the right side of the installation plate. The left end of the threaded rod is fixedly connected to a knob, and the outer surface of the threaded rod is threadedly sleeved with the inner surface of the moving block.

[0011] As a preferred technical solution of the present utility model, a locking gear is fixedly sleeved on the outer surface of the threaded rod between the knob and the installation plate. The outer surface of the locking gear is meshed with a tooth, and the right surface of the tooth is movably connected to the left surface of the installation plate.

[0012] As a preferred technical solution of the present utility model, a fixing block is movably connected to the inner surface of the tooth. The rear surface of the fixing block is fixedly connected to the outer surface of the installation plate, and the lower surface of the fixing block is fixedly connected to a second spring. The bottom end of the second spring is fixedly connected to the inner surface of the tooth.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting the hollow box, clamping plates, limiting plates, first springs and cams, when the cam starts to rotate as a whole, the two clamping plates will move away from each other along the inner surface of the hollow box under the drive of the outer surface of the cam. During this process, the distance between the two clamping plates will gradually increase, thus realizing the clamping function for walkie-talkies of different widths. When the operator releases the turning handle, the two clamping plates will move towards each other under the elastic force of the first springs. Finally, when the two clamping plates contact the walkie-talkie, the walkie-talkie will be fixed between the two clamping plates, thereby ensuring that the walkie-talkie will not fall off during the charging process.

[0015] 2. By providing a hollow box, articulated rods, moving blocks, connecting rods, and threaded rods in the present utility model, when an operator rotates the knob and the threaded rod, the moving block will start to move to the right under the drive of the threaded rod. At the same time, the movement of the moving block will drive the connecting rod and cause the connecting rod to start rotating. The other end of the connecting rod will drive the articulated rod, causing the articulated rod and the hollow box as a whole to start moving upward along the inner surface of the mounting plate. The movement of the hollow box will change the position of the clamping plate, thereby playing a role in changing the clamping position of the clamping plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 5As shown in the figure, the present utility model provides an anti - detachment structure for charging a walkie - talkie, which includes a walkie - talkie 1. The outer surfaces on the left and right sides of the walkie - talkie 1 are both movably connected with clamping plates 3. The number of the clamping plates 3 is two. The rear sides of the outer surfaces of the two clamping plates 3 are both movably connected with hollow boxes 2. The upper and lower sides of the outer surfaces of the two clamping plates 3 are both fixedly connected with limiting plates 4 located inside the hollow boxes 2. The outer surface of the limiting plate 4 is movably connected with the inner surface of the hollow box 2. The outer surface of the limiting plate 4 is fixedly connected with a first spring 5 located inside the hollow box 2. The other end of the first spring 5 is fixedly connected with the inner surface of the hollow box 2. The middle of the inner surface of the hollow box 2 is movably connected with a cam 6. The outer surface of the cam 6 is movably connected with the limiting plate 4. The inner surface of the cam 6 is fixedly sleeved with a round shaft 7. The rear end of the round shaft 7 penetrates through the hollow box 2 and extends to the outside of the hollow box 2 and is fixedly connected with a rotating handle 8.

[0024] When the operator rotates the rotating handle 8, the cam 6, the round shaft 7 and the rotating handle 8 will rotate together. The rotation of the cam 6 will drive the limiting plate 4 and the clamping plate 3, making the two clamping plates 3 as a whole start to move away from each other along the inner surface of the hollow box 2. When the operator releases the rotating handle 8, the two clamping plates 3 as a whole will automatically clamp the walkie - talkie under the elastic force of the first spring 5.

[0025] Among them, the lower surface of the walkie - talkie 1 is movably connected with a charging base 9. The rear surface of the charging base 9 is fixedly installed with a mounting plate 10. The upper surface of the mounting plate 10 is fixedly connected with the lower surface of the hollow box 2.

[0026] The charging base 9 can charge the walkie - talkie 1.

[0027] Among them, the lower surface of the hollow box 2 is fixedly connected with a hinge rod 11. The bottom end of the hinge rod 11 penetrates through the mounting plate 10 and extends to the inside of the mounting plate 10. The outer surface of the hinge rod 11 is movably connected with the inner surface of the mounting plate 10. The bottom of the inner surface of the mounting plate 10 is fixedly connected with a limiting strip 12.

[0028] The whole hollow box 2 can move upward under the limitation of the hinge rod 11.

[0029] Among them, the inner surface of the limiting strip 12 is movably connected with a moving block 13. The lower surface of the moving block 13 is movably connected with the inner surface of the mounting plate 10. The top end of the moving block 13 is hinged with a connecting rod 14. The other end of the connecting rod 14 is hinged with the bottom end of the hinge rod 11.

[0030] When the moving block 13 moves to the right, the connecting rod 14 will start to rotate, and the other end of the connecting rod 14 will drive the hinge rod 11, making the hinge rod 11 and the whole hollow box 2 start to move upward.

[0031] Among them, a threaded rod 15 is movably sleeved on the left surface of the mounting plate 10. The right end of the threaded rod 15 sequentially penetrates through the mounting plate 10 and the moving block 13 and extends to the right side of the mounting plate 10. The left end of the threaded rod 15 is fixedly connected with a knob 16, and the outer surface of the threaded rod 15 is threadedly sleeved with the inner surface of the moving block 13.

[0032] The rotation of the threaded rod 15 will drive the moving block 13, causing the moving block 13 to start moving to the right.

[0033] Among them, a locking gear 17 is fixedly sleeved on the outer surface of the threaded rod 15 between the knob 16 and the mounting plate 10. The outer surface of the locking gear 17 is meshed with a tooth 18, and the right surface of the tooth 18 is movably connected to the left surface of the mounting plate 10.

[0034] When the tooth 18 and the locking gear 17 are meshed with each other, the whole threaded rod 15 will be locked by the tooth 18 and cannot rotate.

[0035] Among them, a fixing block 19 is movably connected to the inner surface of the tooth 18. The rear surface of the fixing block 19 is fixedly connected to the outer surface of the mounting plate 10. The lower surface of the fixing block 19 is fixedly connected with a second spring 20, and the bottom end of the second spring 20 is fixedly connected to the inner surface of the tooth 18.

[0036] The fixing block 19 plays a role in limiting the tooth 18, and the second spring 20 will cause the tooth 18 to automatically reset under the elastic force of the second spring 20.

[0037] The working principle and usage process of the present utility model:

[0038] When an operator needs to charge the walkie-talkie 1, the operator first rotates the rotating handle 8 to make the cam 6 and the round shaft 7 start to rotate. At this time, the two clamping plates 3 as a whole will start to move away from each other under the drive of the cam 6. When the space between the two clamping plates 3 is large enough to accommodate the walkie-talkie 1, the operator places the walkie-talkie 1 inside the charging base 9 for charging and releases the rotating handle 8. At this time, the two clamping plates 3 as a whole will start to move towards each other under the elastic force of the first spring 5, and finally the two clamping plates 3 will contact the walkie-talkie 1 and fix the walkie-talkie 1.

[0039] If it is necessary to adjust the contact position between the clamping plate 3 and the walkie-talkie 1, the operator first pulls the locking tooth 18 to disengage the locking tooth 18 from the engagement with the locking gear 17. At this time, the rotational locking of the locking gear 17, the knob 16 and the threaded rod 15 will be released. Then the operator rotates the knob 16. As the knob 16 and the threaded rod 15 rotate, the moving block 13 will start to move to the right driven by the threaded rod 15. At the same time, the connecting rod 14 will start to rotate due to the movement of the moving block 13, which causes the other end of the connecting rod 14 to drive the articulated rod 11, so that the articulated rod 11 and the hollow box 2 as a whole start to move upward under the limitation of the mounting plate 10. The movement of the hollow box 2 will change the contact position between the clamping plate 3 and the walkie-talkie 1, so that the two clamping plates 3 will not contact the function buttons of the walkie-talkie 1.
