Description

A light-touch clamp-type fixed grounding device

technical field

The utility model relates to a light touch clamp type fixed grounding device.

Background technique

In the maintenance work on the distribution line, it is usually necessary to install a grounding wire between the dropout fuse and the cable head, but the position where the grounding wire is installed is often the wire used by the dropout fuse, the lightning arrester and the cable head. At the soft connection, since there is no place to hang the ground wire, the current installation of the ground wire requires external force to be installed in place, which may cause problems such as loosening of the three-joint joint and excessive force on the cable head, which cannot meet the requirements of wire connection. And mechanical strength requirements, and the installation operation is also difficult, and there are phenomena such as unreliable or unreliable installation, which will affect safety, work efficiency and power supply reliability.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide a light-touch clamp-type fixed grounding device, which has a simple structure, easy operation, no damage to the wire connection and good grounding performance.

The utility model is for achieving above-mentioned purpose, and the utility model adopts following technical scheme:

A light-touch pliers-type fixed grounding device, including a shell, a handle is sleeved on the outer wall of the bottom end of the shell, a clamp is connected to the top of the shell, and a grounding wire is installed on the clamp; a connecting rod is sleeved in the shell One end of the connecting rod is connected with the slider, and the other end is connected with the wrench seat, wherein the wrench seat is connected with a wrench; the connecting rod is sleeved with a spring.

A first groove and a second groove are respectively opened on the slider.

The chuck adopts a tongue-shaped chuck, and the top of the tongue-shaped chuck is sequentially connected by a first arc, a second arc, a third arc, and a fourth arc; and the first arc The radius of the arc is 22mm, the radius of the arc of the second arc is 60mm, the radius of the arc of the third arc is 50mm, and the radius of the arc of the fourth arc is 9mm.

The wrench 4 adopts a pliers wrench.

The beneficial effects of the utility model are as follows: the utility model provides a light-touch clamp-type fixed grounding device, which has a simple structure, convenient operation, no damage to the wire connection and good grounding performance.

Detailed ways

Example 1

As shown in Figure 1 and Figure 2, this embodiment provides a light-touch clamp-type fixed grounding device, including a housing 1, a handle 2 is sleeved on the outer wall of the bottom end of the housing 1, and a chuck is connected to the top of the housing 1 8, and a ground wire 9 is installed on the collet 8; a connecting rod 5 is sleeved in the casing 1, one end of the connecting rod 5 is connected with the slider 7, and the other end is connected with the wrench seat 3, wherein the wrench seat 3 is connected with a wrench 4; the connecting rod 5 is sleeved with a spring 6. The slider 7 is respectively provided with a first groove 10 and a second groove 11 . The first groove 10 and the second groove 11 lock the position of the slider 7 from the upper part and the left and right directions when the slider 7 moves. The collet 8 adopts a tongue-shaped collet, and the top of the tongue-shaped collet is sequentially connected by a first arc 12, a second arc 13, a third arc 14, and a fourth arc 15; and the The arc radius of the first arc 12 is 22mm, the arc radius of the second arc 13 is 60mm, the arc radius of the third arc 14 is 50mm, and the arc radius of the fourth arc 15 is 9mm. The wrench 4 is a pliers wrench.

When using this embodiment for grounding connection, firstly, the operator wears insulating gloves and holds the handle 2, and the handle 2 is also made of rubber material to achieve the insulation effect. Then align the tongue-type clamp 8 to the wire connection that needs to be grounded. Then move the pincer handle 4 upwards, so that the spring 6 pushes the connecting rod 5 to move upwards. When the first groove 10 of the slider 7 installed on the top of the connecting rod 5 contacts the tongue-shaped chuck 8, the wire clamped between the two is conducted with the grounding wire to realize grounding. A light-touch clamp-type fixed grounding device manufactured in this embodiment has a simple structure, is easy to operate, has no damage to the wire connection and has good grounding performance.
