Description

Technical Field

[0001] The utility model relates to the technical field of disassembly equipment for communication modules of electric energy meters, and particularly relates to a pair of pliers. Background Art

[0002] Pliers are a kind of hand-held tools, usually used for clamping, gripping, fixing or twisting objects. They usually consist of two movable gripping parts, and objects can be clamped by squeezing these parts. Pliers can be used for various jobs, such as metal processing, electronic repair, woodworking and household maintenance, etc.

[0003] For example, the Chinese utility model patent (CN116728333A) discloses a disassembly tool for an electric energy meter module, which records: "The disassembly tool for the electric energy meter module is made of inexpensive materials, meets relevant safety requirements, is simple and easy to operate, can greatly improve the module disassembly efficiency, greatly solve the working time of operators, and can also reduce the damage to hands caused by frequent disassembly of modules." It also records the technical problem: "Since the module is small and fits well with the electric meter, it is very laborious to remove it from the electric meter. Coupled with a huge number of detections, a large amount of time will be wasted during the disassembly process, and it is also easy to cause damage to the electric energy meter module, bringing great challenges to the daily work of the staff."

[0004] To sum up, it can be seen that in the prior art, the module clamping opening provided on the plier head is convenient for clamping the module, thereby reducing the damage to the hand caused by frequent disassembly of the module. However, this method has the following technical problems: During the actual use of the device, due to the frequent use of the pliers, the module clamping opening will be worn, resulting in a reduced clamping effect on the electric energy meter module, thereby reducing the disassembly efficiency of the electric energy meter module. And after the module clamping opening is severely worn, the entire pair of pliers cannot be used, resulting in waste of materials. For this reason, this application proposes a pair of pliers, in order to solve the technical problems mentioned in the above patent, and provides a new technical solution. Summary of the Utility Model

[0005] Based on this, in view of the above technical problems, it is necessary to provide a pair of pliers. By inserting the limiting plate on the plier head into the handle, and then under the limitation of the limiting claw and the second torsion spring, the plier head and the handle are combined, thereby realizing the partial disassembly and assembly of the pliers, so that when the plier head and the module chuck are severely damaged in the subsequent process, the plier head and the module chuck can be replaced separately, avoiding the reduction of the clamping effect on the electric energy meter module due to the wear of the module chuck, and further reducing the disassembly efficiency of the electric energy meter module. And the disassembly and replacement of the plier head and the module chuck avoid the situation that the entire device cannot be used after the module chuck is severely damaged, reduce the waste of materials, and thus improve the practicability of the device.

[0006] To solve the above technical problems, the present utility model adopts the following technical solutions:

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.

[0028] As described in the background art, however, in the actual use process of the device, due to the frequent use of the pliers, the module clamping opening will be worn, resulting in a reduction in the clamping effect on the watt-hour meter module, thereby reducing the disassembly efficiency of the watt-hour meter module. Moreover, after the module clamping opening is severely worn, the entire pliers cannot be used, resulting in waste of materials.

[0029] To solve this technical problem, the present utility model provides a pair of pliers, which is applied to the disassembly of watt-hour meter modules.

[0030] Specifically, please refer to Figure 1 - Figure 2 , the pliers specifically include:

[0031] A rotating shaft 2 and two handles 1. The two handles 1 are rotatably connected through the rotating shaft 2. A first torsion spring 3 is sleeved outside the rotating shaft 2. The two ends of the first torsion spring 3 are respectively fixedly connected to the outer walls of the handles 1. Protective sleeves 4 are respectively fixedly connected to the outer walls of the two handles 1. A disassembly and assembly mechanism 5 is arranged at one end of the handle 1 away from the protective sleeve 4. A protection mechanism 6 is arranged outside the handle 1;

[0032] The disassembly and assembly mechanism 5 includes a plier head 7, a module chuck 8, a limiting component, and an auxiliary component. The plier head 7 is closely attached to the outer wall of the handle 1, and the module chuck 8 is fixedly connected to the outer wall of the plier head 7.

[0033] The pliers provided by the utility model can partially disassemble and assemble the pliers by inserting the limiting plate 9 on the pliers head 7 into the handle 1, and then combining the pliers head 7 and the handle 1 under the limitation of the limiting claw 11 and the second torsion spring 12, so as to facilitate the replacement of the pliers head 7 and the module clamp 8 separately when the pliers head 7 and the module clamp 8 are seriously damaged in the future, so as to avoid the reduction of the clamping effect of the electric energy meter module due to the wear of the module clamp 8, and thus the reduction of the disassembly efficiency of the electric energy meter module. Moreover, the disassembly and replacement of the pliers head 7 and the module clamp 8 can avoid the situation that the entire device cannot be used after the module clamp 8 is seriously damaged, thereby reducing the waste of materials and improving the practicability of the device.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] Embodiment 1:

[0036] Please refer to Figure 2 - Figure 4 , a pair of pliers, comprising:

[0037] The limiting component includes a limiting plate 9, and the limiting plate 9 is fixedly connected to one end of the pliers head 7 close to the handle 1. The limiting plate 9 is inserted into the handle 1. The inner wall of the handle 1 is rotatably connected to a rotating shaft 10, and the outer wall of the rotating shaft 10 is fixedly connected to a limiting claw 11 adapted to the limiting plate 9. The limiting claw 11 can impose certain restrictions on the limiting plate 9, and after the limiting plate 9 is successfully inserted into the handle 1, the limiting plate 9 cannot leave the handle 1.

[0038] The auxiliary component includes a second torsion spring 12, and second torsion springs 12 are respectively sleeved on the outer wall of the rotating shaft 10 and at both ends of the limiting claw 11. The second torsion spring 12 can make the limiting claw 11 close to the outer wall of the limiting plate 9, thereby improving the stability of the limiting claw 11 on the limiting plate 9. The two ends of the two second torsion springs 12 are respectively fixedly connected to the outer wall of the limiting claw 11 and the inner wall of the handle 1. The outer wall of the limiting claw 11 is fixedly connected with a fixing plate 13. Moving the fixing plate 13 can drive the limiting claw 11 to rotate accordingly, thereby making the limiting claw 11 leave the top of the limiting plate 9, thereby releasing the restriction on the limiting plate 9, so that the limiting plate 9 can smoothly leave the inside of the handle 1, and then the pliers head 7 and the module chuck 8 can be replaced.

[0039] Through the above-mentioned structural design, the limiting plate 9 on the pliers head 7 is inserted into the handle 1 to a suitable position to complete the assembly of the pliers head 7 and the handle 1. During this process, the limiting claw 11 and the second torsion spring 12 limit the limiting plate 9 so that the limiting plate 9 cannot leave the inside of the handle 1. When the pliers head 7 and the module clamp 8 are severely damaged later, the pliers head 7 and the module clamp 8 can be replaced separately. By moving the fixing plate 13, the limiting claw 11 can be driven to rotate along with the rotating shaft 10, so that the second torsion spring 12 is deformed accordingly, thereby releasing the restriction on the limiting plate 9, and then the pliers head 7 can be pulled to make the limiting plate 9 leave the inside of the handle 1, the fixing plate 13 can be loosened, and the new pliers head 7 can be reinserted into the inside of the handle 1.

[0040] Embodiment 2:

[0041] The pliers provided in Example 1 are further optimized, specifically, as Figure 3 - Figure 5 As shown, the protection mechanism 6 includes a fixed shell 16, a protective shell 18, a blocking component, and a sliding component. The outer wall of the handle 1 is fixedly connected to the fixed shell 16, and the outer wall of the fixed shell 16 is slidably connected to the protective shell 18. The protective shell 18 is slidably connected to the top of the handle 1. The protective shell 18 can provide certain protection for the fixed plate 13, thereby reducing the situation where the fixed plate 13 is accidentally touched by the outside world.

[0042] The blocking assembly includes a blocking plate 14, and the top of the pliers head 7 is fixedly connected to the blocking plate 14 adapted to the protective shell 18, and the outer wall of the blocking plate 14 is fixedly connected to a rubber ring 15. The blocking plate 14 and the rubber ring 15 can block the opening on the protective shell 18, thereby strengthening the connection between the pliers head 7 and the handle 1, and reducing the entry of external dust into the interior of the handle 1, thereby improving the service life of the device and reducing the situation where the protective shell 18 is accidentally slipped.

[0043] The sliding assembly includes a T-shaped block 17, the top of the fixed shell 16 is fixedly connected with the T-shaped block 17, the T-shaped block 17 is slidably connected to the inner wall of the protective shell 18, the inner wall of the fixed shell 16 is fixedly connected with a fixed column 19, the outer wall of the fixed column 19 is slidably connected to the inner wall of the protective shell 18, and the outer sleeve of the fixed column 19 is provided with a reset spring 20. Under the action of the reset spring 20, the protective shell 18 can be slid to a certain extent, and then the protective shell 18 can be released to return to its original position, thereby improving the convenience of device operation. The two ends of the reset spring 20 are respectively fixedly connected to the inner walls of the fixed shell 16 and the protective shell 18.

[0044] Through the above structural design, before the fixing plate 13 needs to be toggled, hold the protective shell 18 and slide it a certain distance towards the position of the fixed shell 16. During this process, the protective shell 18 gradually disengages from the rubber ring 15, and the protective shell 18 slides on the outer wall of the fixed column 19. At the same time, the return spring 20 is compressed accordingly. After the protective shell 18 slides to a suitable position, the fixing plate 13 can be operated. After the jaw 7 is replaced, the protective shell 18 can be released, and then under the action of the elastic force of the return spring 20, the protective shell 18 can return to its initial position, making the protective shell 18 contact with the rubber ring 15.
