Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of parallel groove clamps, and particularly relates to a parallel groove clamp. Background Art
[0002] Parallel groove clamps are mainly used for the connection of aluminum stranded wires or aluminum conductor steel-reinforced stranded wires with medium and small cross-sections and the steel stranded wires of overhead lightning conductors at positions not bearing tension, and can also be used for the jumper connection of non-straight-line towers. They are widely used in the power industry. In the power industry, overhead lines need to be set up. As a part of the numerous urban and rural power grids, the performance of parallel groove clamps directly affects reliable power supply. However, in the process of using existing parallel groove clamps, the parallel groove clamps cannot clamp wires with different thicknesses, thus reducing the versatility and compatibility during the use of parallel groove clamps, and making the wires prone to looseness or falling off during long-term operation, thereby affecting the normal operation of the line. Summary of the Utility Model
[0003] The main purpose of the utility model is to provide a parallel groove clamp, which can effectively solve the problems in the background art.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A parallel groove clamp includes a base block. A lower arc groove is formed in the middle of the upper end of the base block. Two limiting sliding grooves are formed at the front end and the rear end of the base block respectively. A lower arc clamping cotton board is placed in the lower arc groove. Two limiting sliding blocks are fixedly connected to the front outer surface and the rear outer surface of the lower arc clamping cotton board respectively. A support frame is fixedly connected to the right part of the upper end of the base block. Through T-shaped sliding grooves are formed at the front part and the rear part of the left end of the support frame. An upper arc clamping cotton board is arranged directly above the lower arc clamping cotton board. Two downward pressing circular grooves are formed in the upper part of the outer surface of the upper arc clamping cotton board. Two T-shaped long blocks are fixedly connected to the left part of the outer surface of the upper arc clamping cotton board. One end of each of the two T-shaped long blocks far away from the upper arc clamping cotton board passes through the T-shaped sliding groove and the two are fixedly connected to a hand pull rod together. Through screw holes are formed at the front part and the rear part of the upper end of the support frame. The support frame is threadedly and movably connected with threaded screwing columns through the two screw holes respectively. The lower ends of the two threaded screwing columns are fixedly connected with downward pressing abutting columns.
[0006] Preferably, the sizes of the four limiting sliding blocks are respectively adapted to the sizes of the four limiting sliding grooves.
[0007] Preferably, the lower arc clamping cotton board is slidably connected with the base block through the four limiting sliding blocks and the four limiting sliding grooves respectively.
[0008] Preferably, the hand pull rod does not contact the left end of the support frame.
[0009] Preferably, the upper arc-shaped cotton clamping plate and the lower arc-shaped cotton clamping plate have the same size, dimensions and structure.
[0010] Preferably, the two lower pressing circular grooves respectively match the lower ends of the two lower pressing abutting columns in size.
[0011] Preferably, the two lower pressing abutting columns are not fixed to the upper arc-shaped cotton clamping plate.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. By providing the lower arc-shaped cotton clamping plate and the upper arc-shaped cotton clamping plate, the lower arc-shaped cotton clamping plate is limited and slid with the base block through four limit sliders and four limit chutes. Additionally, the upper arc-shaped cotton clamping plate is inserted and slidably connected with the support frame through a T-shaped long block and a T-shaped chute. Thus, with the combined use of these components, by manually pulling the hand lever, the upper arc-shaped cotton clamping plate can be driven to cooperate with the lower arc-shaped cotton clamping plate to clamp electric wires of different thicknesses. In addition, both the lower arc-shaped cotton clamping plate and the upper arc-shaped cotton clamping plate are made of cotton-clamping material, which can clamp and protect the outer surface of the electric wire and avoid damaging the electric wire.
[0014] 2. By providing a threaded screw post and a lower pressing abutting column, two lower pressing circular grooves adapted to the size of the lower pressing abutting column are formed in the upper part of the outer surface of the upper arc-shaped cotton clamping plate. Thus, when a person manually turns the threaded screw post, the threaded screw post can drive the lower pressing abutting column to move downward and tightly abut against the upper arc-shaped cotton clamping plate, thereby better fixing the electric wire and preventing the electric wire from falling off from the parallel groove clamp.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0024] A parallel groove clamp includes a base block 1. A lower arc groove 2 is opened in the middle of the upper end of the base block 1. Two limiting sliding grooves 3 are opened at the front end and the rear end of the base block 1. A lower arc clamping cotton plate 4 is placed in the lower arc groove 2. Two limiting sliding blocks 5 are fixedly connected to both the front part of the outer surface and the rear part of the outer surface of the lower arc clamping cotton plate 4. A support frame 6 is fixedly connected to the right part of the upper end of the base block 1. Through T-shaped sliding grooves 7 are opened at both the front part and the rear part of the left end of the support frame 6. An upper arc clamping cotton plate 8 is arranged directly above the lower arc clamping cotton plate 4. Two downward pressing round grooves 12 are opened in the upper part of the outer surface of the upper arc clamping cotton plate 8. Two T-shaped long blocks 9 are fixedly connected to the left part of the outer surface of the upper arc clamping cotton plate 8. One end of each of the two T-shaped long blocks 9 far from the upper arc clamping cotton plate 8 passes through the T-shaped sliding groove 7 and is fixedly connected to a hand pull rod 10 together. Through screw holes 13 are opened at both the front part and the rear part of the upper end of the support frame 6. The support frame 6 is threadedly movably connected to threaded screwing posts 11 through the two screw holes 13. Lower pressing abutting posts 14 are fixedly connected to the lower ends of the two threaded screwing posts 11.
[0025] In this embodiment, the four limit sliders 5 are respectively adapted to the sizes of the four limit slots 3, and the lower arc-shaped cotton-clamping plate 4 is slidably connected to the base block 1 through the four limit sliders 5 and the four limit slots 3. By sliding the four limit sliders 5 connected to the lower arc-shaped cotton-clamping plate 4 in the four limit slots 3 opened on the base block 1, the position of the lower arc-shaped cotton-clamping plate 4 can be adjusted, so that the lower arc-shaped cotton-clamping plate 4 can better contact with the surface of the wire, the hand pull rod 10 does not contact with the left end of the support frame 6, and the upper arc-shaped cotton-clamping plate 8 has the same size and structure as the lower arc-shaped cotton-padded plate 4, and the two downward pressing circular grooves 12 are respectively matched with the lower end sizes of the two downward pressing columns 14. By moving the hand pull rod 10 up and down, the upper arc-shaped cotton-padded plate 8 and the lower arc-shaped cotton-padded plate 4 can be brought close to each other, so that the overhead line is located between the upper arc-shaped cotton-padded plate 8 and the lower arc-shaped cotton-padded plate 4, which can realize clamping of wires of different specifications and thicknesses, and the downward pressing circular groove 12 is adapted to the downward pressing column 14, which can greatly enhance the clamping strength and stability of the parallel groove wire clamp on the wire.
[0026] It should be noted that the utility model is a parallel groove wire clamp. During use, firstly, the four limit sliders 5 on the lower arc-shaped cotton clamping plate 4 are located in the four limit slide grooves 3 opened on the base block 1 for limit sliding, so that the lower arc-shaped cotton clamping plate 4 can be flexibly moved to a position, thereby being able to adapt to wires of different diameters. On the other hand, the upper arc-shaped cotton clamping plate 8 is moved in the T-shaped slide groove 7 through the T-shaped long block 9, and the staff manually moves the hand pull rod 10 up and down, so that the hand pull rod 10 can synchronously drive the upper arc-shaped cotton clamping plate 8 to move, so that under the joint use of the upper arc-shaped cotton clamping plate 8 and the lower arc-shaped cotton clamping plate 4, wires of different sizes can be clamped. When encountering larger diameter wires, the lower arc-shaped cotton-padded plate 4 and the upper arc-shaped cotton-padded plate 8 can be stretched apart by a certain distance, and for smaller diameter wires, the lower arc-shaped cotton-padded plate 4 and the upper arc-shaped cotton-padded plate 8 can also fit tightly. Secondly, by providing a threaded screw column 11, personnel manually rotate the threaded screw column 11, and the threaded screw column 11 can drive the lower pressure column 14 to move downward, which can further strengthen the fixing force of the wire and effectively prevent the wire from falling off the parallel groove wire clamp. In addition, because the lower arc-shaped cotton-padded plate 4 and the upper arc-shaped cotton-padded plate 8 are both made of cotton-padded material, they can play a buffering and protective role on the outer surface of the wire when clamping, which can avoid damage to the wire and enable the line to work normally.
