Description

A multi-purpose grounding clamp

【Technical field】

The utility model relates to the field of electric tools, in particular to a grounding clamp.

【Background technique】

In the urban power grid, the cable cross-connection system is often damaged due to man-made or natural reasons, and even a floating voltage will be generated, which endangers the safety of maintenance personnel. The method of eliminating the floating voltage in the prior art generally adopts the method of grounding the single end of the metal sheath. This method of elimination requires the use of grounding clamps to connect the metal sheath to the ground. In the prior art, the grounding clamp can only be clamped from the outside of the metal sheath. In some cases, for example, when the metal sheath is very close to other electrical equipment, the grounding clamp is inconvenient to clamp from the outside of the metal sheath. In this case, Existing grounding clamps cannot be used. At the same time, since the claws of the grounding pliers are fixedly connected to the heads of the grounding pliers, the purpose of the grounding pliers is single.

【Content of utility model】

In order to solve the aforementioned problems, the utility model provides a new type of grounding pliers, which solves the problem of insufficient adaptability caused by the fact that the grounding pliers can only be clamped from the outside of the metal sheath.

In order to achieve the above purpose, the utility model adopts the following technical solution: a multi-purpose grounding pliers, including a clamping part, a connecting part and a grip handle, the connecting part includes two connecting pieces hinged to each other, the connecting piece The two ends are respectively connected to the clamping part and the grip handle, the clamping part is provided with claws, and the orientation of the claws is set opposite or facing the back, and a connecting ring is set on the clamping part, The claw is detachably mounted on the clamping portion through the connecting ring.

Further, the connecting ring is fixed to the clamping part by a fastener, the clamping part is provided with a through hole, and the fastener passes through the connecting ring and enters the through hole.

Furthermore, the fastener is a bolt, the inner wall of the through hole is provided with an internal thread, and the bolt cooperates with the internal thread.

Furthermore, along the length direction of the clamping portion, at least two through holes are provided.

Optionally, the claw has an included angle with the clamping portion, and the included angle ranges from 1° to 15°.

Optionally, the top end of the clamping part is provided with a wiring hole for externally connecting electric wires.

Optionally, the holding handle is provided with a locking mechanism, and when the clamping part is in a clamped state, the locking mechanism locks the position of the holding handle.

Optionally, the holding handle is a 10KV insulating gate lever.

After adopting the technical scheme, the utility model has the following advantages:

A multi-purpose grounding pliers, comprising a clamping part, a connecting part and a handle, the connecting part includes two connecting pieces hinged to each other, and the two ends of the connecting piece are respectively connected to the clamping part and the holding handle , the clamping part is provided with claws, and the orientation of the claws is set oppositely or backwards, and a connecting ring is set on the clamping part, and the claws are detachably installed through the connecting ring On the clamping part: when the claws are set oppositely, the multi-purpose grounding pliers can be clamped on the outside of the wire or the metal protective sheath of the wire. In some cases, such as the wire protective sheath and other equipment When very close, the grounding pliers are not convenient to clamp the metal protective sheath of the wire from the outside, so in this case, reverse the direction of the claws and set them to the back, so that the grounding pliers can extend into the metal protective sheath from the inner wall At the same time, the claws are detachably connected through the connecting ring, which can be removed when there is no need to clamp the wires. At this time, the grounding pliers can be used as ordinary pliers, which increases the function of the grounding pliers.

The connecting ring is fixed with the clamping part by a fastener, and the clamping part is provided with a through hole, and the fastener passes through the connecting ring and enters the through hole: the connecting ring is connected by the fastener Fixed on the clamping part, the structure is simple and the installation is easy.

The fastener is a bolt, and the inner wall of the through hole is provided with an internal thread, and the bolt cooperates with the internal thread: the pre-tightening can be conveniently realized through the bolt, and the bolt is highly replaceable, which reduces the maintenance cost.

Along the length direction of the clamping part, there are at least two through holes: the arrangement of multiple through holes makes the position of the claw in the length direction of the clamping part adjustable. When it is tight and the depth of penetration is relatively shallow, the jaws can be installed at the topmost position of the clamping part, which greatly enhances the adaptability of the grounding clamp.

The claw and the clamping part have an included angle, and the angle range of the included angle is 1° to 15°: when the clamping part is clamped, the left and right sides have a certain angle, in the prior art The claws are all perpendicular to the clamping part. In this case, the claws are not clamped vertically by the wire or the metal protective sleeve of the wire, which may easily cause slippage or elongate the insulation skin of the wire. Therefore, the claws and the clamp The holding part has a certain angle, so that the claws on the left and right sides are in the collinear position when clamping, so as to avoid the occurrence of slippage or elongation of the insulation skin of the wire.

The top end of the clamping part is provided with a wiring hole for externally connecting electric wires: through the connection hole, the clamping part is conveniently connected to the wire.

The gripping handle is provided with a locking mechanism, and when the clamping part is in a clamped state, the locking mechanism locks the position of the gripping handle: when the clamping part is clamped, the gripping handle is locked by the locking mechanism The position of the grounding clamp is fixed, which can reduce the working intensity of the laborers, and it is not necessary to maintain the clamping state of the grounding clamp with force all the time, freeing the hands of the laborers, so that the laborers can perform other operations at the same time.

The gripping handle is a 10KV insulated brake rod: a higher-grade insulating brake rod is used to improve the insulation performance of the grounding clamp, and it also has the advantages of light weight, high mechanical strength, wide application range, and strong moisture resistance.

These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and accompanying drawings.
