Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electric power work protection devices, and particularly relates to a grounding wire ear protection device. Background Art
[0002] The grounding wire is one of the safety tools for electric power work protection. The copper ear of the grounding wire is connected to the grounding wire by crimping, and after crimping, it is sealed and protected with a heat shrinkable tube. Since the ear is fixedly installed at a corresponding position, when the operator operates improperly, the grounding wire may swing and bend greatly from different angles, making the copper wire at the interface between the ear and the copper core of the grounding wire bend greatly and easily wear and break, affecting the wiring performance and being inconvenient for the use of the ear and the grounding wire. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a grounding wire ear protection device for preventing the grounding wire from being worn and broken.
[0004] The utility model adopts the following technical scheme:
[0005] A grounding wire ear protection device includes a grounding wire and an ear. The grounding wire includes a grounding wire outer shell wrapped outside it. The ear is fixed to one end of the grounding wire. The device further includes a protective sleeve detachably sleeved on the outer periphery of the grounding wire. The protective sleeve includes a protective sleeve body with one end clamped to the grounding wire, a clamping member arranged between the protective sleeve body and the grounding wire, and a plurality of anti-swing support mechanisms arranged on the inner wall of the protective sleeve body and capable of supporting the grounding wire outer shell. The plurality of anti-swing support mechanisms are spaced apart along the inner wall of the protective sleeve body. When the grounding wire is bent, the plurality of anti-swing support mechanisms can abut against the outer side of the grounding wire outer shell to reduce the bending amplitude of the grounding wire.
[0006] Further, the anti-swing support mechanism includes a support plate capable of moving back and forth relative to the inner wall of the protective sleeve body and a reset assembly arranged between the support plate and the inner wall of the protective sleeve body.
[0007] Further, the reset assembly includes a fixed sleeve formed by extending towards the support plate on the inner wall of the protective sleeve body, a guide rod movably arranged in the fixed sleeve, and a reset spring sleeved on the outer peripheral surface of the fixed sleeve with one end connected to the fixed sleeve and the other end connected to the support plate.
[0008] Further, the support plate includes a fixed section opposite to the grounding wire outer shell and an abutting section arranged on one side of the fixed section and inclined outwards. A moving space is formed between the abutting section and the grounding wire outer shell.
[0009] Further, the clamping member includes an installation hole formed in the protective sleeve body for the ear and the grounding wire to pass through, and a rubber sleeve fixedly arranged on the inner wall of the installation hole. The rubber sleeve can be sleeved on the outer peripheral surface of the grounding wire and abut tightly against the grounding wire.
[0010] Further, the protective sleeve body is a cylindrical cover body.
[0011] Further, two wire ears are provided, which are respectively fixedly arranged at both ends of the ground wire.
[0012] Further, the two wire ears include a ground wire ear, and the protective sleeve is sleeved on one side of the ground wire close to the ground wire ear.
[0013] As can be seen from the above description of the present utility model, compared with the prior art, the beneficial effects of the present utility model are as follows: In this application, a detachable protective sleeve is sleeved on the outer periphery of the ground wire, and the specific structure of the protective sleeve is defined. When the ground wire is in use and bends, the protective sleeve bends towards the wire ear at the end of the ground wire. At this time, each anti-sway support mechanism abuts against the outer side of the ground wire housing to support the ground wire housing, thereby reducing the bending amplitude of the ground wire, preventing the ground wire from being worn and broken, ensuring that the connection between the ground wire and the wire ear at the end of the ground wire is not affected, and maintaining the grounding performance of the ground wire; in addition, through the clamping member provided between the protective sleeve body and the ground wire, the protective sleeve is fixed on the ground wire to ensure a tight connection between the protective sleeve and the ground wire.

After the wire ear 2 and the ground wire 1 pass through, the rubber sleeve 35 abuts against the outer peripheral surface of the ground wire 1 and is mutually extruded, so that the protective sleeve 3 is fixed on the ground wire 1; further, the protective sleeve body 31 is a cylindrical cover body.
