Utility model content

The purpose of the utility model is to provide a portable combined short-circuit grounding rod, which is convenient and fast to install, reliable to fix, convenient to store, occupies a small space, uses a grounding cap for grounding operation, and does not need the use of grounding pins.

In order to achieve the above object, the utility model provides a portable combined short-circuit grounding rod, which includes a grounding clamp, several connecting rods, a support fixing mechanism and a grounding cap, and several connecting rods are connected by threads, and the connecting rods It is a hollow rod, and a ground nut is fixed on one side of the ground clamp, and the ground nut is connected to the ground cap through a wire, and the wire is passed through the connecting rod, and the ground cap is connected to the ground cap. The bottom of the rod is screwed, the side of the ground cap is fixed with a connecting piece, and the supporting and fixing mechanism is sleeved on the connecting rod.

Preferably, the supporting and fixing mechanism includes a fixing ring and legs, the inside of the fixing ring is screwed to the outside of the connecting rod, and there are three legs, and the three legs are evenly distributed on the outside of the fixing ring , the legs and the fixing ring are hinged through hinges.

Preferably, the bottom of the ground cap is a conical bottom, and a conductive ring is fixed inside the conical bottom, and the conductive ring is connected to a wire.

Preferably, the ground clamp includes a fixed frame and a movable splint, the bottom of the movable splint is fixed with a threaded rod, the threaded rod passes through the bottom of the fixed frame and is fixedly connected with the connecting rod, and the top of the fixed frame is set There are stops.

Therefore, the utility model adopts a portable combined short-circuit grounding rod with the above-mentioned structure, which is convenient and fast to install, reliable to fix, convenient to store, occupies a small space, uses a grounding cap for grounding operation, and does not need the use of grounding pins.

The technical solutions of the present utility model will be further described in detail through the drawings and embodiments below.

Detailed ways

Example

Figure 1 is a structural schematic diagram of a portable combined short-circuit grounding rod of the present invention. As shown in the figure, a portable combined short-circuiting grounding rod includes a grounding clip, several connecting rods 3, a support fixing mechanism 5 and a grounding cap 6 , several connecting rods 3 are connected by threads, and the connecting rods 3 are hollow insulating rods. The grounding clamp includes a fixed frame 1 and a movable splint 2. The bottom of the movable splint 2 is fixed with a threaded rod, and the threaded rod passes through the bottom of the fixed frame 1 and is fixedly connected with the connecting rod 3. The top of the fixed frame 1 is provided with a stopper 11, which is convenient for hanging to prevent the cable from detaching from the grounding clamp during the mounting process. One side of the ground clamp is fixed with a ground nut 12, the ground nut 12 is connected to the ground cap 6 through the wire 4, the wire 4 is passed through the connecting rod 3, the ground cap 6 is screwed to the bottom of the connecting rod 3, and the side of the ground cap 6 is fixed There is a connecting piece 62. The bottom of the grounding cap 6 in this embodiment is a conical bottom, which is convenient for insertion into the ground. A conductive ring 61 is fixed inside the conical bottom, and the conductive ring 61 is connected with the wire 4, which is convenient for connection. When in use, when the length of several connecting rods 3 can be in contact with the ground, directly insert the grounding cap 6 into the ground, and when the length of several connecting rods 3 is set in the air and is not enough to install another connecting rod 3, unscrew the grounding cap 6 , lengthen the wire inside the storage and connecting rod 3, insert the grounding cap 6 into the ground, and complete the grounding operation.

The supporting and fixing mechanism 5 is sleeved on the connecting rod 3. The supporting and fixing mechanism 5 includes a fixing ring 51 and a leg 53. The inner side of the fixing ring 51 is connected with the outer thread 31 of the connecting rod 3. There are three supporting legs 53, each of which is Distributed on the outside of the fixed ring 51, the legs 53 and the fixed ring 51 are hinged through the hinge 52, and the support and fixing mechanism 5 fixes the connecting rod 3 through the legs, which improves the safety.

Therefore, the utility model adopts a portable combined short-circuit grounding rod with the above-mentioned structure, which is convenient and fast to install, reliable to fix, convenient to store, occupies a small space, uses a grounding cap for grounding operation, and does not need the use of grounding pins.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: It is still possible to make modifications or equivalent replacements to the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
