Description

Technical Field

[0001] This utility model belongs to the technical field of high-voltage grounding clamps, specifically a high-voltage grounding clamp. Background Technology

[0002] High-voltage grounding clamps are safety devices used to temporarily short-circuit and ground de-energized equipment. Their function is to prevent the equipment from being suddenly powered on or to prevent the induced voltage from nearby high-voltage equipment from causing harm to the human body when high-voltage equipment is shut down for maintenance or other work. At the same time, they discharge the residual charge of the de-energized equipment. The bottom opening of the clamp has no limit structure, which makes it easy for it to come loose.

[0003] Meanwhile, a high-voltage grounding wire device with application number CN202320399297.8 is described as follows: "The high-voltage grounding wire device includes a grounding wire, a retractable insulating operating rod, fasteners, and a wire clamp detachably connected to the insulating operating rod. The interior of the insulating operating rod is hollow, and a terminal is fixedly connected to the end of the grounding wire. The end of the wire clamp has an installation groove that matches the shape of the terminal. The grounding wire passes through the insulating operating rod, the terminal is fitted into the installation groove, and the fastener passes through the wire clamp and the terminal to fix the grounding wire to the wire clamp."

[0004] In the use of existing high-voltage grounding wire devices, the anti-disengagement structure inside the clamp is used to lock the wire in place and complete the positioning operation. However, the bottom opening does not have an anti-disengagement structure, which causes the clamp to become unstable when touched by the outside, resulting in a stable high charge release.

[0005] Therefore, a high-voltage grounding clamp is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a high-voltage grounding clamp with a limiting component structure that increases the clamp opening. This structure forms a positioning point below the high-voltage line, preventing the clamp from detaching from the outside of the wire, thus making the clamp more stable in use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage grounding clamp, including a handle, a grip fixedly disposed at the bottom end of the handle, a clamp fixedly disposed at the top end of the handle, an anti-disengagement clamp fixedly disposed inside the clamp, and a spring-loaded component further comprising inside the handle and located below the opening of the clamp; the spring-loaded component includes a support plate rotatably disposed inside the through groove of the handle, and a rubber pad slidably disposed on the outer side of the support plate; the outer side of the clamp also includes a clamp protection component; the clamp protection component includes a connecting tube fixed to one side of the clamp, and a protective cover slidably sleeved on the outer side of the connecting tube and fitting against one side of the clamp.

[0008] Preferably, a telescopic shaft is fitted to one side of the bottom of the support plate, and a spring is sleeved on the outside of the telescopic shaft.

[0009] Preferably, a fixing block is fixedly provided at the other end of the telescopic shaft, and the fixing block is fixedly provided with the handle, and the spring is located between the telescopic shaft and the fixing block.

[0010] Preferably, a transverse groove is provided inside the transverse side of the support plate, and a guide rod is provided inside the transverse groove and fixedly installed with the rubber pad.

[0011] Preferably, square grooves are provided on both sides of the connecting pipe, and the inner wall of the protective cover is provided with sliders corresponding to the vertical groove positions of the square grooves.

[0012] Preferably, the bottom of the protective cover is symmetrically provided with insert plates on both sides, and a positioning frame is inserted into the outer side of the insert plate and fixedly disposed with the wire clamp.

[0013] Preferably, the interior of the protective cover also includes a connecting plate structure with a connecting plate fixed to one side of the clamp by screws, and a wire passing through the opening of the protective cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a support plate structure in the pop-up assembly in conjunction with a rubber pad to clamp the wire clamp to the outside of the high-voltage line. After releasing the handle, the weight of the handle itself can drive the rubber pad on the outside of the support plate below the wire clamp opening to press against the outside of the parallel high-voltage line, thus performing an effective limiting operation and reducing the risk of the wire clamp coming off the outside of the high-voltage line during use, making it extremely stable in use.

[0016] 2. This utility model uses a protective cover structure installed on the outside of the connector to form a mutually sealing protective component structure for the connecting plate. Therefore, it can effectively protect the connection between the clamp and the connecting plate when used in rainy or snowy weather. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As shown in Figures 1 to 5, this utility model provides a high-voltage grounding clamp, including a handle 1, a handle 2 fixedly provided at the bottom end of the handle 1, a clamp 3 fixedly provided at the top end of the handle 1, an anti-disengagement clamp 4 fixedly provided inside the clamp 3, and a spring-loaded component 5 also provided inside the handle 1 and below the opening of the clamp 3.

[0026] The pop-up assembly 5 includes a support plate 51 that is rotatably disposed inside the through groove of the handle 1, and a rubber pad 56 is slidably disposed on the outer side of the support plate 51; the support plate 51 and the rubber pad 56 can provide balanced support.

[0027] The outer side of the wire clamp 3 also includes a wire clamp protection component; the wire clamp protection component includes a connecting tube 6 fixed to one side of the wire clamp 3, a protective cover 7 is slidably sleeved on the outer side of the connecting tube 6 and fits against one side of the wire clamp 3, pushing the protective cover 7 into the outer side of the connecting tube 6 to form a mutually closed and connected protective structure to protect the connecting plate 9.

[0028] Specifically, a telescopic shaft 53 is attached to one side of the bottom of the support plate 51, and a spring 54 is sleeved on the outside of the telescopic shaft 53. A fixing block 52 is fixedly installed at the other end of the telescopic shaft 53, and the fixing block 52 is fixedly installed with the handle 1. The spring 54 is located between the telescopic shaft 53 and the fixing block 52. The spring 54 pushes the support plate 51 to maintain its rotational unfolded state through elastic potential energy, thereby limiting the parallel high-voltage lines.

[0029] Furthermore, a transverse groove 55 is provided inside the transverse side of the support plate 51. A guide rod 57 is provided inside the transverse groove 55 and is fixedly installed with the rubber pad 56. The rubber pad 56 can move inside the transverse groove 55 of the support plate 51 through the guide rod 57 to unfold and position itself.

[0030] It is worth noting that square grooves 8 are provided on both sides of the connecting pipe 6, and the inner wall of the protective cover 7 is provided with sliders corresponding to the vertical grooves of the square grooves 8. The bottom of the protective cover 7 is symmetrically provided with insert plates 10 on both sides. The outer side of the insert plate 10 is inserted with a positioning frame 11 and fixedly installed with the wire clamp 3. The interior of the protective cover 7 also includes a connecting plate structure with a connecting plate 9 fixed to one side of the wire clamp 3 by screws, and a wire passes through the opening of the protective cover 7. The protective cover 7 slides inside the connecting pipe 6 by the built-in slider. After the bottom insert plate 10 is lifted out of the positioning frame 11, the slider of the protective cover 7 moves to the position of the square groove 8 of the connecting pipe 6, and the protective cover 7 can be removed from the outside of the connecting pipe 6. The operation is simple and convenient.

[0031] Among them, the wire clip 3 and the anti-detachment clip 4 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller and a switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0032] Working principle and process:

[0033] The user tightens the connecting plate 9 onto the outside of the clamp 3 with screws to position it, completing the connection between the connecting plate 9 and the clamp 3. Then, the protective cover 7 is removed. Using the square slot 8 of the connecting pipe 6, the built-in slider of the protective cover 7 is pushed into the outside of the connecting pipe 6. The protective cover 7 is then slid down, and the insert plate 10 at the bottom of the protective cover 7 is inserted into the positioning frame 11 to limit the position of the protective cover 7. This completes the sealing and protection operation, placing the connecting plate 9 inside the protective cover 7. Holding the handle 2, the clamp 3 is inserted into the outside of the high-voltage line. The anti-detachment clamp 4 clamps and limits the high-voltage line, completing the use of the clamp 3. Excess charge is released, and the clamp 3 is positioned against the parallel high-voltage line using the rubber pad 56 on the outside of the support plate 51 in the pop-up assembly 5, limiting the position of the clamp 3. Finally, the support plate 51 is lifted by the telescopic shaft 53 on the fixing block 52 at the bottom of the support plate 51, in conjunction with the spring 54, protecting the support plate 51. The outer rubber pad 56 is positioned below the high-voltage line, forming a limit at the lower opening of the clamp 3 to position the clamp 3 and prevent it from falling off during use. The protective cover 7 slides inside the connector 6 via a built-in slider. After the bottom insert 10 is removed from inside the positioning frame 11, the slider of the protective cover 7 moves to the square groove 8 of the connector 6, allowing the protective cover 7 to be removed from the outside of the connector 6. The operation is simple and convenient.
