[0002] The lead clamp is a commonly used electrical hardware. Its main structure includes an upper wire clamp, a lower wire clamp and a bolt assembly. Its working principle is to insert the main wire into a clamp hole in the lead clamp, and insert the shunt wire into another clamp hole. The main wire and the shunt wire are clamped by the bolt assembly, the upper wire clamp and the lower wire clamp. The upper wire clamp and the lower wire clamp themselves have conductive properties. In this way, the lead clamp not only realizes the spatial merger of the main wire and the shunt wire, but also realizes the power transmission between the two.

DETAILED DESCRIPTION
[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0022] See also Figure 1-4 The utility model provides a technical solution: an electric power installation lead clamp, comprising a bracket plate 1, and two mounting plates 2 are fixedly mounted on both side surfaces of the bracket plate 1.
[0023] The specific configuration and function of the clamping device 3 and the reinforcing device 4 will be described in detail below.
[0024] In this embodiment: a clamping device 3 is provided between the inner walls on both sides of the bracket plate 1, and the clamping device 3 includes a threaded rod 31, and the threaded rod 31 is rotatably connected between the inner walls on both sides of the bracket plate 1. A rotating wheel 32 is fixedly installed on the surface of the threaded rod 31, and the threads on the surface of the threaded rod 31 are reverse threads with the rotating wheel 32 as the center.
[0025] In this embodiment, the setting of the rotating wheel 32 plays the effect of driving the threaded rod 31 to rotate.
[0026] Specifically, a vertical rod 33 is fixedly installed between the inner walls at both ends of the bracket plate 1, and two Z-shaped plates 34 are threadedly connected to the surface of the threaded rod 31.
[0027] In this embodiment, the threaded rod 31 is provided to drive the Z-shaped plate 34 to move on the surface of the vertical rod 33 .
[0028] Specifically, the Z-shaped plate 34 is slidably connected with the threaded rod 31 and the vertical rod 33, and a clamp ring 35 is fixedly installed on the side of the horizontal end of one side of the Z-shaped plate 34. The setting of the clamp ring 35 has the effect of clamping and fixing the power lead.
[0029] In this embodiment: the inner bottom surface of the support plate 1 is provided with a reinforcing device 4, and the reinforcing device 4 includes a slide groove 401, and the slide groove 401 is provided on the inner bottom surface of the support plate 1. A movable plate 402 is slidably connected to the inner surface of the slide groove 401, and a limit frame 403 is fixedly installed on the surface of one end of the movable plate 402 away from the slide groove 401. When the clamp ring 35 has finished clamping and fixing the power lead, the sliding plate 407 is slid to move the sliding plate 407 on the surface of the vertical pole 406. The movement of the sliding plate 407 on the surface of the vertical pole 406 will squeeze the spring 411, so that the spring 411 is compressed. At the same time, the movement of the sliding plate 407 on the surface of the vertical pole 406 also drives the insertion rod 408 to move. The insertion rod 408 moves so that it moves out of the inside of the socket 409. The insertion rod 408 and the socket 409 are separated, so that the displacement plate 405 loses its limit in the inside of the groove 404. At this time, the displacement plate 405 can be slid, and the displacement plate 405 is in the groove 404. The movement of the part drives the movable plate 402 to move inside the slide groove 401, and the movement of the movable plate 402 inside the slide groove 401 drives the limit frame 403 to move. When the limit frame 403 moves to a position where the two clamping rings 35 are located inside it, the slide plate 407 is released, and the rebound force of the spring 411 is used to reinsert the insertion rod 408 into the corresponding insertion hole 409 to fix the position of the displacement plate 405 inside the groove 404 at this time. Through the cooperation of the above-mentioned structure, the limit frame 403 can limit the distance between the two clamping rings 35, thereby further improving the clamping effect of the clamping ring 35.
[0030] Specifically, a groove 404 is formed on the side of the bracket plate 1 , and a displacement plate 405 is slidably connected inside the groove 404 . One end of the displacement plate 405 away from the groove 404 is fixedly connected to the moving plate 402 .
[0031] In this embodiment, the arrangement of the displacement plate 405 has the effect of driving the moving plate 402 to move inside the sliding groove 401 .
[0032] Specifically, a vertical pole 406 is fixedly installed on the top surface of the displacement plate 405, a slide plate 407 is slidably connected to the surface of the vertical pole 406, an insertion rod 408 is fixedly installed on the bottom surface of the slide plate 407, a plurality of insertion holes 409 are evenly arranged on the inner bottom surface of the bracket plate 1, a limit plate 410 is fixedly installed on the surface of one end of the vertical pole 406 away from the displacement plate 405, and a spring 411 is fixedly installed between the limit plate 410 and the slide plate 407.
[0033] In this embodiment, the setting of the spring 411 has the effect of limiting the position of the slide plate 407 on the surface of the vertical rod 406.
[0034] Working principle: By setting the clamping device 3, when the device needs to be used, the user first uses the mounting plate 2 to install and fix the bracket plate 1 in a suitable position, and then passes the power lead between the two clamping rings 35, and then rotates the rotating wheel 32. The rotation of the rotating wheel 32 drives the threaded rod 31 to rotate. Since the threads on the surface of the threaded rod 31 are reverse threads with the rotating wheel 32 as the center, when the rotating wheel 32 drives the threaded rod 31 to rotate, the two Z-type plates 34 threadedly connected on the surface of the vertical rod 33 move toward each other on the surface of the vertical rod 33. The two Z-type plates 34 move toward each other on the surface of the vertical rod 33, driving the two clamping rings 35 to move toward each other. The two clamping rings 35 move toward each other to clamp and fix the power lead, completing the clamping operation of the power lead. Through the cooperation of the above-mentioned structure, the purpose of clamping and fixing the power lead is achieved, and the disadvantages brought by the use of bolts are avoided. After the clamp ring 35 has finished clamping and fixing the power lead, the sliding plate 407 is slid to move the sliding plate 407 on the surface of the vertical rod 406. The movement of the sliding plate 407 on the surface of the vertical rod 406 will squeeze the spring 411, so that the spring 411 is compressed. At the same time, the movement of the sliding plate 407 on the surface of the vertical rod 406 also drives the insertion rod 408 to move. The insertion rod 408 moves so that it moves out of the inside of the socket 409. The insertion rod 408 and the socket 409 are separated, so that the displacement plate 405 loses its limit in the inside of the groove 404. At this time, the displacement plate 405 can be slid, and the displacement plate 405 is in the groove 404. The movement of the part drives the movable plate 402 to move inside the slide groove 401, and the movement of the movable plate 402 inside the slide groove 401 drives the limit frame 403 to move. When the limit frame 403 moves to a position where the two clamping rings 35 are located inside it, the slide plate 407 is released, and the rebound force of the spring 411 is used to reinsert the insertion rod 408 into the corresponding insertion hole 409 to fix the position of the displacement plate 405 inside the groove 404 at this time. Through the cooperation of the above-mentioned structure, the limit frame 403 can limit the distance between the two clamping rings 35, thereby further improving the clamping effect of the clamping ring 35.
