Description

Technical Field

[0001] The invention belongs to the technical field of wire clamps, and in particular relates to an easily locked distribution network wire clamp. Background Art

[0002] Distribution network clamps are devices used to connect and fix wires in power distribution systems. They can help ensure the stability and safety of power lines in various environments. Parallel wire clamps are a type of distribution network accessory used to connect multiple power conductors together. They are often used in the parallel connection of wires in distribution lines. Their main function is to connect two or more power conductors through a clamp and maintain smooth current transmission.

[0003] During the use of existing parallel groove wire clamps, special tools are usually required to screw the bolts so that the clamp block can press and fix the cables. It is inconvenient to operate at high altitudes and there is a risk of bolts falling. In addition, the position of the groove for placing the cables is relatively fixed, which is not convenient to adjust according to different incoming line directions, and the use effect is not good. For this reason, we propose an easy-to-lock distribution network wire clamp. Summary of the invention

[0004] The purpose of the present invention is to provide an easily locked distribution network wire clamp to solve the problem in the above background technology that the existing parallel groove wire clamps for fixing cables require special tools to tighten the bolts, which is inconvenient to operate at high altitudes and is not convenient to adjust the groove position according to different incoming line directions.

[0005] To achieve the above object, the present invention provides the following technical solution: an easily lockable distribution network clamp, comprising: A first wire clamp body and a second wire clamp body arranged side by side with the first wire clamp body, wherein the first wire clamp body is provided with a wiring groove for placing the cable, and a copper-plated layer is fixed inside the wiring groove; A first connecting block, fixed to the edge of the upper surface of the first wire clamp body; A limit block is rotatably mounted on both ends of the first connecting block, and one end of the limit block has a hook plate, and a side wall of the hook plate is provided with a slot; A second connecting block is fixed to the edge of the upper surface of the second clamp body, and a rotation adjustment component electrically connected to the copper plating layer is provided between the second connecting block and the first connecting block; The clamping block assembly is arranged inside the first wire clamp body. When the limiting block presses the cable inside the groove, the clamping block assembly cooperates with the clamping groove to fix the limiting block.

[0006] Preferably, the clamping block assembly includes a clamping block, a clamping spring and a pull rod. The clamping block is slidably installed on the inner edge of the first wire clamp body, and one end face of the clamping block is provided with a clamping spring. The pull rod is fixed to one end of the clamping block, and one end of the pull rod penetrates through the first wire clamp body and extends to the outside of the first wire clamp body.

[0007] Preferably, the cross-section of the clamping block is wedge-shaped.

[0008] Preferably, four limiting blocks are provided, and every two of the limiting blocks are symmetrically arranged at both ends of the first connecting block or the second connecting block respectively.

[0009] Preferably, the rotation adjustment assembly includes a rotation block, a pressing spring and a friction block. A rotation block is fixed to one side wall of the second connecting block. A rotation groove is correspondingly formed in one side wall of the first connecting block opposite to the rotation block, and a friction block is fixed to one end inside the rotation groove. A pressing spring that presses the rotation block against the friction block is sleeved outside the rotation block.

[0010] Preferably, the rotation adjustment assembly further includes a conductive sleeve, a conductive pin and a support spring. The conductive sleeve is slidably installed on one side wall of the first connecting block, and a conductive pin is slidably connected inside the conductive sleeve. One end of the conductive pin is fixed to the copper plating layer, and the other end of the conductive pin is provided with a support spring that cooperates with the conductive sleeve.

[0011] Preferably, the cross-section of the conductive pin is "T"-shaped, and a plurality of conductive pins are evenly distributed along the circumferential direction of the conductive sleeve.

[0014] Preferably, the hook plate is arc-shaped, and a plurality of card slots are evenly distributed along one side wall of the hook plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) By providing a first connecting block, a limiting block, a second connecting block, a hook plate, a card slot and a clamping block assembly, it is avoided that when fixing a cable to the inside of a parallel groove clamp, it is necessary to tighten a plurality of bolts and a special tool is required, which is rather laborious for high-altitude operation. This device does not require a special tool and can quickly press and fix the cable to the inside of the wiring groove, completing the quick locking of the cable. The operation is simple, improving the convenience of high-altitude installation and increasing the practicability of the device.

[0016] (2) By providing a rotating block, a clamping spring, a friction block, a conductive sleeve, a conductive foot and a supporting spring, the relative positions of the two pairs of cable placement grooves of the parallel groove wire clamp are prevented from being fixed. When the cables come from different directions, it is inconvenient to adjust the positions of the placement grooves to adapt to the incoming direction of the cables. The device can adjust the positions of the first wire clamp body and the second wire clamp body according to the incoming direction of the cables, thereby adjusting the direction of the wiring groove to adapt to the cables. The operation is simple, the application range of the device is expanded, and it is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Preferably, the rotation adjustment assembly 7 includes a rotating block 701, a clamping spring 702 and a friction block 703. The rotating block 701 is fixed to one side wall of the second connecting block 5.

At this time, the compression spring 702 is compressed and shortened, and the rotating block 701 rotates inside the rotating groove to adjust the wiring groove on the second wire clamp body 2 to correspond to one of the cables, and the wiring groove on the first wire clamp body 1 corresponds to the other cable. Release the second wire clamp body 2, and the rotating block 701 contacts and rubs against the friction block 703 under the elastic push of the compression spring 702. The rotation of the rotating block 701 is restricted by a large friction force.
