Description

Technical Field

[0001] This utility model relates to the field of grounding clamp technology, and in particular to a grounding clamp. Background Technology

[0002] Grounding clamps are used to hang grounding wires on various lines during power outage work. Existing grounding clamps consist of components such as clamps, insulating covers, and grounding rings. Hanging a grounding wire on the grounding clamp at one end of the line at the corresponding point can help troubleshoot line faults; hanging grounding wires on the grounding clamps on both sides of the line to be repaired can enable power outage repair.

[0003] Currently, the wire clamp, insulating cover, and grounding ring are all independent components. Usually, the wire clamp is simply placed inside the insulating cover, and there is a gap between the wire clamp and the inner wall of the insulating cover. When encountering sudden severe weather conditions such as strong winds, the wire clamp may be affected by the wind and swing, which will make the wire clamp prone to friction with the side wall of the insulating cover. This not only reduces the service life of the wire clamp, but also affects the normal use of the grounding ring and the wire. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide a grounding clamp.

[0005] The technical solution of this utility model is as follows: a grounding clamp includes a clamp body, which is composed of two half-shells. An insulating cover is provided on the outside of the clamp body. The insulating cover is composed of an upper cover and a lower cover. Fixed boxes are fixedly connected to both ends of the top of the upper cover. Fixed rings are slidably connected inside the fixed boxes. Clamping rods are fixedly connected inside the fixed rings. Springs are sleeved on the outside of the clamping rods. The end of the clamping rod away from the fixed box extends into the interior of the insulating cover and is fixedly connected to a fixed plate. Rubber blocks are fixedly connected to the side of the fixed plate away from the clamping rods. An airbag is built into the interior of the lower cover.

[0006] By adopting the above technical solution, the air supply component can continuously inflate the inside of the airbag, causing the airbag to expand continuously and come into contact with the bottom of the clamp body. The reaction force of the spring can push the lever and the fixing plate to move, thereby causing the rubber block to come into contact with the top of the clamp body. In this way, the upper and lower parts of the clamp body can come into contact, thereby strengthening the connection between the insulating cover and the clamp body.

[0007] In a preferred embodiment, an air supply assembly is provided on the outside of the insulating cover. The air supply assembly includes a suction cylinder fixedly installed on the outside of the insulating cover. A piston plate is slidably connected inside the suction cylinder, and a pull rod is slidably connected inside the suction cylinder. An air inlet is provided inside the suction cylinder. One end of the pull rod is fixedly connected to the central axis of the piston plate, and an air outlet pipe is fixedly connected to the outside of the suction cylinder.

[0008] By adopting the above technical solution, external air can be drawn into the suction cylinder through the air inlet by the reciprocating movement of the pull rod.

[0009] In a preferred embodiment, the end of the air outlet pipe away from the suction cylinder extends into the interior of the airbag, and an air outlet valve is fixedly connected to the side of the airbag away from the air outlet pipe. The end of the air outlet valve away from the airbag extends to the outside of the insulating cover.

[0010] By adopting the above technical solution and setting an exhaust valve, workers can expel excess gas from the airbag.

[0011] In a preferred embodiment, the outer side of the insulating cover is provided with a snap-fit ​​assembly, which includes a snap-fit ​​plate fixedly connected to the outer side of the lower cover, and two snap-fit ​​slots are formed inside the snap-fit ​​plate. An elastic snap-fit ​​member that cooperates with the snap-fit ​​slots is fixedly connected to the outer side of the upper cover.

[0012] By adopting the above technical solution, the use of elastic clips and slots can achieve the purpose of quickly fixing the insulating cover, thereby reducing the construction time of workers on the grounding clamp.

[0013] In a preferred embodiment, the spring is disposed between the fixing ring and the inner wall of the fixing box, a grounding ring is installed between the two half-shells, and two locking bolts are provided at the top of the clamp body, and the two half-shells are connected by the locking bolts.

[0014] By adopting the above technical solution and setting a grounding ring, it is possible to prevent sudden power surges in equipment, prevent induced voltage from harming the human body, and discharge residual charge from equipment that has been de-energized.

[0015] In a preferred embodiment, the suction cylinder has air holes spaced at equal intervals on the side near the pull rod.

[0016] By adopting the above technical solution and setting the air holes, the air pressure inside the suction cylinder is kept constant.

[0017] In a preferred embodiment, the upper cover and the lower cover are rotatably connected, and a wire hole is provided inside the insulating cover on one side of the grounding ring.

[0018] By adopting the above technical solution and setting wire holes, it is possible to install electrical wires.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. In this utility model, when an insulating cover needs to be installed on the outside of the clamp body, the worker can use the snap-fit ​​assembly to snap the upper cover and the lower cover together, thereby fixing the clamp body inside the insulating cover. Then, the air supply assembly continuously inflates the inside of the airbag, causing the airbag to expand continuously and come into contact with the bottom of the clamp body. Through the reaction force of the spring, the locking rod and the fixing plate can be moved, thereby causing the rubber block to come into contact with the top of the clamp body. In this way, the upper and lower parts of the clamp body can come into contact, thereby strengthening the connection between the insulating cover and the clamp body. This makes it less likely to shake in sudden severe weather conditions such as strong winds, thereby reducing wear on the surface of the clamp body.

[0021] 2. In this utility model, the use of elastic clips and slots can achieve the purpose of quickly fixing the insulating cover, thereby reducing the construction time of workers on the grounding clamp. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-5 A grounding clamp includes a clamp body 1, which is composed of two half-shells. An insulating cover 4 is provided on the outside of the clamp body 1. The insulating cover 4 is composed of an upper cover and a lower cover. Fixed boxes 12 are fixedly connected to both ends of the top of the upper cover. Fixed rings 15 are slidably connected inside the fixed boxes 12. Locking rods 14 are fixedly connected inside the fixed rings 15. Springs 13 are sleeved on the outside of the locking rods 14. The end of the locking rod 14 away from the fixed box 12 extends into the interior of the insulating cover 4 and is fixedly connected to a fixing plate 19. Rubber blocks 18 are fixedly connected to the side of the fixing plate 19 away from the locking rod 14. An airbag 6 is built into the interior of the lower cover. When the insulating cover 4 needs to be installed outside the clamp body 1, the working... Operators can use the snap-fit ​​assembly to snap the upper cover and lower cover together, thereby fixing the wire clamp body 1 inside the insulating cover 4. Then, the air supply assembly continuously inflates the airbag 6, causing the airbag 6 to expand and come into contact with the bottom of the wire clamp body 1. The reaction force of the spring 13 pushes the locking rod 14 and the fixing plate 19 to move, thereby causing the rubber block 18 to come into contact with the top of the wire clamp body 1. In this way, the wire clamp body 1 can come into contact with the top and bottom, thereby strengthening the connection between the insulating cover 4 and the wire clamp body 1. This makes it less likely to shake in sudden severe weather conditions such as strong winds, thereby reducing wear on the surface of the wire clamp body 1.

[0030] Specifically, an air supply assembly is provided on the outside of the insulating cover 4. The air supply assembly includes a suction cylinder 8 fixedly installed on the outside of the insulating cover 4. A piston plate 16 is slidably connected inside the suction cylinder 8, and a pull rod 17 is slidably connected inside the suction cylinder 8. An air inlet is provided inside the suction cylinder 8. By reciprocating the movement of the pull rod 17, external air can be drawn into the suction cylinder 8 through the air inlet. Then, by blocking the air inlet with your hand and pushing the pull rod 17, the gas inside the suction cylinder 8 can be filled into the airbag 6, thereby achieving the purpose of abutting the bottom of the wire clamp body 1. One end of the pull rod 17 is fixedly connected to the central axis of the piston plate 16. An air outlet pipe 9 is fixedly connected to the outside of the suction cylinder 8. The air outlet pipe 9 is away from the suction cylinder 6. One end of the suction cylinder 8 extends into the interior of the airbag 6. An air outlet valve 7 is fixedly connected to the side of the airbag 6 away from the air outlet pipe 9. The end of the air outlet valve 7 away from the airbag 6 extends to the outside of the insulating cover 4. The air outlet valve 7 allows workers to expel excess gas from the airbag 6. A snap-fit ​​assembly is provided on the outside of the insulating cover 4. The snap-fit ​​assembly includes a snap plate 10 fixedly connected to the outside of the lower cover. Through the cooperation of the elastic snap piece 5 and the snap groove 11, the insulating cover 4 can be quickly fixed, thereby reducing the construction time of the workers for the grounding clamp. Two snap grooves 11 are opened inside the snap plate 10. An elastic snap piece 5 that cooperates with the snap groove 11 is fixedly connected to the outside of the upper cover.

[0031] Specifically, spring 13 is set between the inner wall of fixed ring 15 and fixed box 12. Grounding ring 2 is installed between the two half-shells. The grounding ring 2 can prevent the equipment from being suddenly powered on, prevent the induced voltage from causing harm to the human body, and discharge the residual charge of the powered-off equipment. Two locking bolts 3 are set at the top of the clamp body 1. The two half-shells are connected by locking bolts 3. Air holes are equidistantly opened on the side of the suction cylinder 8 near the pull rod 17. The air holes are set so that the air pressure in the suction cylinder 8 is always constant. The upper cover and the lower cover are rotatably connected. The inside of the insulating cover 4 and on the side of the grounding ring 2 are opened with wire holes. The wire holes are set so that wires can be installed.

[0032] Working principle: First, the operator places the grounding ring 2 inside the clamp body 1 and the wire into the wire hole. Then, using the locking bolt 3, the grounding ring 2 and the wire are installed inside the clamp body 1. Simultaneously, the operator can use the elastic clip 5 and the slot 11 to engage the upper and lower covers, thus fixing the clamp body 1 inside the insulating cover 4. Next, pulling the lever 17 draws external air into the suction cylinder 8 through the air inlet. Then, by blocking the air inlet with the hand and pushing the lever 17, the gas in the suction cylinder 8 is filled into the airbag 6, thereby achieving the desired connection. The purpose of the clamp body 1 is to abut against the bottom. The airbag 6 is an existing structure with one-way valves at both ends. When the airbag 6 expands continuously, it abuts against the bottom of the clamp body 1. Through the reaction force of the spring 13, it can push the lever 14 and the fixing plate 19 to move, so that the rubber block 18 abuts against the top of the clamp body 1. In this way, the clamp body 1 can abut against the top and bottom to strengthen the connection between the insulating cover 4 and the clamp body 1. This makes it less likely to shake in sudden severe weather conditions such as strong winds, thereby reducing the wear on the surface of the clamp body 1.
