Description

Technical Field

[0001] The utility model relates to the field of electric power engineering, and more specifically, to a fixing device for the ground wire in an electric engineering. Background Technique

[0002] The ground wire in an electric engineering is a conductive material used to establish a grounding connection for electrical equipment and electrical systems. The main function of the ground wire is to ensure the safety of personnel and equipment and provide a current return path so that in case of a fault, the current can be quickly guided to the ground. The ground wire is usually made of conductive materials such as copper and aluminum. It can be a single wire or a grounding grid composed of a group of wires. In the prior art, the ground wire is usually connected to the ground wire row.

[0003] In the prior art, the ground wire is usually fixed to the ground wire row by screws. In this way, during the operation, the screws are easy to fall off and get lost after being removed, which takes time to find and is not conducive to improving work efficiency. Moreover, the connection between the wire body and the wire ear is prone to bending, which is not conducive to the use of the ground wire.

[0004] Therefore, we make an improvement and propose a fixing device for the ground wire in an electric engineering. Content of the Utility Model

[0005] The purpose of the utility model is to address the current situation where: usually, the ground wire is fixed to the ground wire row by screws. In this way, during the operation, the screws are easy to fall off and get lost after being removed, which takes time to find and is not conducive to improving work efficiency. Moreover, the connection between the wire body and the wire ear is prone to bending, which is not conducive to the use of the ground wire.

[0006] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0007] A fixing device for the ground wire in an electric engineering to improve the above problems.

[0008] Specifically, this application is as follows:

[0009] It includes a bottom plate, on which a fixing column is fixedly installed. A first sliding rod is slidably connected to the bottom plate. A second sliding rod is hinged to the first sliding rod. A connecting plate is fixedly installed at the top of the second sliding rod. Above the fixing column, there is a mounting plate. A rotating column is rotatably connected to the mounting plate. A pressing sleeve is fixedly installed at the bottom of the rotating column. There is a limiting mechanism on the rotating column. An extension plate is fixedly installed on the front surface of the bottom plate. A clamping mechanism is arranged on the extension plate. A connecting mechanism is arranged inside the pressing sleeve.

[0010] As a preferred technical solution of this application, the limiting mechanism includes a limiting piece fixedly installed on the rotating column, and the limiting piece fits with the mounting plate.

[0011] As a preferred technical solution of the present application, the clamping mechanism includes a support plate fixedly installed on the extension plate, and an elastic clip is integrally formed on the support plate.

[0012] As a preferred technical solution of the present application, the connecting mechanism includes a screw rod fixedly installed in the pressing sleeve.

[0013] As a preferred technical solution of the present application, a threaded groove is provided in the fixed column, and the threaded groove matches the screw rod.

[0014] As a preferred technical solution of the present application, the connecting plate is fixedly connected to the mounting plate.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the solution of the present application:

[0017] 1. First, put the wire ear on the fixed column, then rotate the rotating column. The rotating column drives the pressing sleeve to move downward (simultaneously driving the limiting piece to move downward, the limiting piece drives the mounting plate to move downward, the mounting plate drives the connecting plate to move downward, the connecting plate drives the second sliding rod, and the second sliding rod drives the first sliding rod to move downward). Then rotate the rotating column again, the rotating column drives the pressing sleeve to rotate, the pressing sleeve drives the screw rod to rotate, and the screw rod then enters the fixed column along the threaded groove in the fixed column until the bottom of the pressing sleeve presses against the wire ear, which realizes convenient operation and can effectively prevent the screw from falling and getting lost. It solves the problem that in the prior art, the ground wire is usually fixedly installed on the ground wire row through screws. In this way, during the operation process, the screw is easily dropped and lost after being removed, and it takes time to find it, which is not conducive to improving work efficiency.

[0018] 2. By placing the wire body in the elastic clip, the problem that the connection between the wire body and the wire ear is prone to bending is effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS
