Description

Technical Field

[0001] This utility model relates to the field of power installation technology, and in particular to a lead clamp for power equipment installation. Background Technology

[0002] The lead wire clamp can secure the optical cable leading down or up from the pole to the pole, preventing it from wobbling and thus avoiding wear and tear on the optical cable.

[0003] For example, a lead wire clamp for power equipment installation, authorized by publication number "CN222508006U," is designed to be suitable for special working conditions where the main conductor is energized, ensuring the safety of operators. However, this device is not convenient for quickly clamping and fixing wires of different diameters. It requires adjustments to the movable frame and other structures to clamp wires of varying diameters, and this adjustment process takes time. Therefore, it is not convenient for targeted clamping of different wires. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing a lead wire clamp for power equipment installation, which can be used to clamp wires of different diameters.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This lead wire clamp for power equipment installation includes a first clamp and a second clamp. The left end of the first clamp is attached to the second clamp. The first clamp has a pulling structure inside. The surfaces of the first clamp and the second clamp are provided with multiple grooves. The inner walls of the grooves on the surface of the first clamp are all fixedly connected to a first rubber pad.

[0006] Further improvements include the pulling structure comprising tension springs and straight rods, with one end of each tension spring fixedly connected to the inner wall of the first clamp, and the other end of each tension spring fixedly connected to a plurality of straight rods, one end of each straight rod fixedly connected to the second clamp.

[0007] To further improve the design, each groove on the surface of the second clamp is provided with a second rubber pad, and the second clamp is threadedly connected to the first clamp by bolts.

[0008] To further improve the design, two support plates are fixedly connected to the left end of the second clamp.

[0009] Further improvements include fixing the inner walls of the support plates on both sides to the two ends of the handle.

[0010] The beneficial effects of this utility model are as follows: Through the cooperation of the pull structure and the first clamp, the operator fixes the first clamp to the surface of the power equipment by passing a screw through the through hole on the surface of the first clamp. By pulling the handle, the second clamp drives four sets of straight rods, which stretch four tension springs, separating the second clamp from the first clamp. The lead wire is then placed into the corresponding hole. Releasing the handle allows the second clamp to engage with the first clamp under the action of the tension springs, clamping the lead wire tightly. Simultaneously, the operator connects the first and second clamps with bolts, ensuring the lead wire is stably clamped. This allows for targeted clamping of lead wires of different diameters, making the clamping process faster for the operator. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] See attached document Figure 1-5 In this embodiment, a lead clamp for installing power equipment includes a first clamp 1 and a second clamp 7. The left end of the first clamp 1 is attached to the second clamp 7. The first clamp 1 is provided with a pulling structure 2 inside. The surfaces of the first clamp 1 and the second clamp 7 are provided with multiple grooves. The inner walls of the grooves on the surface of the first clamp 1 are all fixedly connected with a first rubber pad 4.

[0019] The grooves on the surface of the second clamp 7 are provided with second rubber pads 3. The second clamp 7 is threadedly connected to the first clamp 1 by bolts 8. Two support plates 6 are fixedly connected to the left end of the second clamp 7. The inner walls of the two support plates 6 are fixedly connected to the two ends of the handle 5 respectively.

[0020] The pulling structure 2 includes a tension spring 201 and a straight rod 202. One end of each tension spring 201 is fixedly connected to the inner wall of the first clamp 1. The elastic coefficient of the tension spring 201 is determined according to actual needs and meets the working requirements. The other end of each tension spring 201 is fixedly connected to each straight rod 202. One end of each straight rod 202 is fixedly connected to the second clamp 7.

[0021] Working principle:

[0022] When installing leads for electrical equipment:

[0023] The operator fixes the first clamp 1 to the surface of the power equipment by passing screws through the through holes on the surface of the first clamp 1. By pulling the handle 5, the operator moves the second clamp 7, causing the second clamp 7 to move the four sets of straight rods 202. The straight rods 202 stretch the four tension springs 201, separating the second clamp 7 from the first clamp 1. The lead wire is then placed into the corresponding hole (the first clamp 1 and the second clamp 7 are selected with different diameter grooves depending on the lead wire to be installed). The operator releases the handle 5, and under the action of the tension springs 201, the second clamp 7 cooperates with the first clamp 1 to clamp the lead wire. The first rubber pad 4 and the second rubber pad 3 prevent damage to the lead wire surface. At the same time, the operator connects the first clamp 1 and the second clamp 7 with bolts 8 to ensure that the lead wire is stably clamped.

[0024] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
