Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a wire clamp fixing device. Background Art

[0002] Wire clamps are iron or aluminum metal accessories that can be fixed on the wire. Most of them need to withstand large tensile forces during operation, and some also need to ensure good electrical contact. Wire clamps are mainly divided into: equipment wire clamps, fuse clamps, wire holding clamps, terminal wire clamps, piercing grounding wire clamps, tightening wire clamps, insulation piercing wire clamps, double-headed wire clamps, lead-in wire clamps, etc.

[0003] When the existing device is in use, because its clamping part is fixed and the clamping force cannot be adjusted, the fixing effect for cables of different diameters is poor and the cables cannot be effectively fixed, which is relatively inconvenient. In addition, when fixing the cables, the existing device is unstable and easily causes wear to the cable skin. After long-term use, the cable skin is easily damaged, which is relatively dangerous. Utility Model Content

[0004] The purpose of the utility model is to provide a wire clamp fixing device to solve the problems that the existing device proposed in the above background technology cannot be used to fix cables of different diameters when in use, which is inconvenient; and the existing device is prone to cause wear on the cable surface when fixing the cable, which is dangerous.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire clamp fixing device, comprising an upper clamp and a lower clamp, the upper clamp is located above the lower clamp, bolts are provided through the upper and lower sides of the upper clamp and the lower clamp, a first arc surface groove is symmetrically provided on the lower side of the upper clamp, a second arc surface groove is symmetrically provided on the upper side of the lower clamp, a clamping groove is provided on the upper side of the lower clamp, an arc-shaped gasket is movably provided on the lower side of the lower clamp, an adjusting nut is symmetrically connected to the upper side of the upper clamp, an adjusting screw is provided through the upper side of the upper clamp, the adjusting screw is symmetrically provided, the adjusting nut is threadedly connected to the adjusting screw, and an arc-shaped pressure plate is rotatably provided on the lower end of the adjusting screw.

[0006] Preferably, the bolt is movably connected to the upper clamp and the lower clamp, and the bolt passes through the bottom center of the inner side of the clamping groove.

[0007] Preferably, the arc-shaped gasket is movably sleeved on the outside of the bolt, and the arc-shaped pressure plate is located on the inner side of the first arc-surface groove.

[0008] Preferably, the first arc surface groove corresponds to the second arc surface groove, and the lower side of the upper clamp is clamped with the inner side of the clamping groove.

[0009] Preferably, the lower end of the adjusting screw is fixedly connected to a limiting disk, a limiting groove is provided on the upper side of the arc-shaped pressure plate, and the limiting disk is rotatably connected to the limiting groove.

[0010] Preferably, a decompression spring is symmetrically connected to the bottom of the inner side of the second arc surface groove, and an arc-shaped receiving plate is fixedly connected to the upper side of the decompression spring.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1) When the device is used, bolts are used to connect the upper clamp, the lower clamp and the arc-shaped gasket together. The arc-shaped gasket is on the lower side of the lower clamp to prevent slipping and protect it. Then the cable is clamped between the first arc surface groove and the second arc surface groove. The bolt is adjusted to clamp the upper clamp and the lower clamp. Then the cable is placed on the upper side of the arc-shaped receiving plate, and the adjusting screw is rotated to drive the arc-shaped pressure plate to descend vertically, press the cable, and fix the cable between the arc-shaped receiving plate and the arc-shaped pressure plate. This design can ensure that the device has a good fixing effect on cables of different diameters and a better clamping effect.

[0013] 2) When the device clamps the cable, the arc-shaped receiving plate and the arc-shaped pressure plate in the device are both made of rubber with a rounded surface, so it will not cause wear on the cable surface. However, the conventional device has a poor clamping effect, and the cable is constantly moving and rubbing on the metal edge of the device, which is easy to damage the surface.
