Description

Technical Field

[0001] This utility model belongs to the field of grounding clamp technology, specifically relating to a stable grounding clamp that is easy to attach and detach. Background Technology

[0002] Grounding wires are widely used in power systems, installed on both sides of the work site to prevent electric shocks caused by electrostatic induction from nearby live parts or sudden power surges from equipment. Currently, commonly used grounding clamps rely on spring clips on both sides to hold the conductor, depending entirely on the clamp's own friction. Because the bottom of the clamp is open, it is prone to detaching from the clamped conductor in strong winds or other inclement weather, affecting normal power maintenance work and significantly increasing safety hazards for workers. Furthermore, grounding clamps are prone to jamming during installation and removal, making removal difficult or inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a stable grounding clamp that is easy to attach and detach, in order to solve the problems mentioned in the background art.

[0004] The purpose of this utility model is achieved as follows: a stable grounding clamp that is easy to attach and detach includes a main rod, an operating handle is provided on the lower side of the main rod, a hook is provided on the upper end of the main rod, a wiring ring is provided on the outer side of the hook, and clamping plates are symmetrically arranged inside the hook. The lower end of the clamping plate is hinged to the hook through a hinge shaft, and a driving mechanism is provided between the hook and the clamping plate.

[0005] The operation involves creating an anti-slip texture on the surface.

[0006] The driving mechanism includes a driving gear, a driving frame, and a rotating shaft. The driving gear is sleeved and fixed to the outside of the hinge shaft. The driving frame is located inside the hook body. Both ends of the driving frame are provided with toothed plates, which mesh with the driving gear. The main body rod is hollow inside. The rotating shaft is fixedly installed at the upper end of the operating handle. The operating handle is inserted into the main body rod through the rotating shaft. The right end of the driving frame is movably connected to the rotating shaft through a connecting rod. A top block is provided at the upper end of the rotating shaft. A baffle is provided inside the main body rod. A compression spring is provided between the baffle and the top block. A through groove is provided at the bottom of the main body rod. A leaf plate is provided on the outside of the rotating shaft.

[0007] The hook body is provided with a limiting groove inside, and the drive frame is provided with a limiting shaft on the outside. The limiting shaft and the limiting groove cooperate with each other.

[0008] The clamping piece is connected to the middle of the drive gear, and the tooth plate has a through hole inside, through which the clamping piece passes through the tooth plate.

[0009] A lever is provided on the outer side of the bottom of the main rod.

[0010] The operation involves setting a pointer on the top outer side.

[0011] The beneficial effects of this utility model are as follows: The symmetrical design of the clamping plates inside the hook body, which are hinged to the hook body via hinge pins, ensures stability and uniform force when clamping the wire, avoiding loosening or damage to the clamp due to uneven force. The opening and closing range of the clamping plates can accommodate wires of different diameters, improving the adaptability and flexibility of the clamp. The design of the connecting ring allows the grounding wire to be easily hung on the hook body. The hollow design inside the main body rod reduces the overall weight and facilitates the arrangement and installation of the internal drive mechanism, making the entire clamp structure more compact and reasonable. The design of the drive mechanism makes the opening and closing of the clamping plates simple and efficient. Simply rotating the operating handle drives the drive gear to rotate via the rotating shaft, connecting rod, and drive frame, thereby driving the clamping plates to open and close, achieving quick attachment and detachment of the grounding wire.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Example 1

[0021] like Figure 1 As shown, a stable grounding clamp that is easy to attach and detach includes a main rod 1, an operating handle 3 on the lower side of the main rod 1, a hook body 2 on the upper end of the main rod 1, a wiring ring 4 on the outer side of the hook body 2, and clamping pieces 5 symmetrically arranged inside the hook body 2. The lower end of the clamping pieces 5 is hinged to the hook body 2 through a hinge shaft 6, and a driving mechanism is provided between the hook body 2 and the clamping pieces 5.

[0022] The surface of the operating handle 3 is provided with anti-slip texture. The anti-slip texture allows for a safer and more stable grip on the operating handle 3, ensuring the accuracy of operation.

[0023] When using this invention, hold the operating handle 3, utilizing its anti-slip texture to ensure a stable grip. Pass one end of the grounding wire through the connecting ring 4, ensuring the grounding wire is securely attached to the hook body 2. The operating handle 3 moves the main body rod 1 and hook body 2, hooking the hook body 2 onto the upper side of the wire. The drive mechanism moves the clamping plates 5, using the clamping plates 5 on both sides to tightly hold the wire, preventing the hook body 2 from falling off the upper side of the wire.

[0024] This utility model features convenient operation, stable clamping, and effectively improves the safety of power construction.

[0025] Example 2

[0026] like Figure 1-6 As shown, a stable grounding clamp that is easy to attach and detach includes a main rod 1, an operating handle 3 on the lower side of the main rod 1, a hook body 2 on the upper end of the main rod 1, a wiring ring 4 on the outer side of the hook body 2, and clamping pieces 5 symmetrically arranged inside the hook body 2. The lower end of the clamping pieces 5 is hinged to the hook body 2 through a hinge shaft 6, and a driving mechanism is provided between the hook body 2 and the clamping pieces 5.

[0027] For better performance, the surface of the handle 3 is textured with anti-slip material. This anti-slip texture allows for a safer and more stable grip on the handle 3, ensuring accurate operation.

[0028] For better performance, the drive mechanism includes a drive gear 7, a drive frame 8, and a rotating shaft 11. The drive gear 7 is sleeved and fixed to the outside of the hinge shaft 6. The drive frame 8 is located inside the hook body 2. Both ends of the drive frame 8 are provided with toothed plates 9, which mesh with the drive gear 7. The main body rod 1 is hollow inside. The rotating shaft 11 is fixedly installed on the upper end of the operating handle 3. The operating handle 3 is inserted into the main body rod 1 through the rotating shaft 11. The right end of the drive frame 8 is movably connected to the rotating shaft 11 through a connecting rod 10. A top block 12 is provided at the upper end of the rotating shaft 11. A baffle 13 is provided inside the main body rod 1. A compression spring 14 is provided between the baffle 13 and the top block 12. A through groove 16 is provided at the bottom of the main body rod 1. A leaf plate 15 is provided on the outside of the rotating shaft 11.

[0029] For better performance, a limiting groove 17 is provided inside the hook body 2, and a limiting shaft 18 is provided on the outside of the drive frame 8. The limiting shaft 18 cooperates with the limiting groove 17. The cooperation design of the limiting groove 17 and the limiting shaft 18 ensures the stability and accuracy of the drive frame 8 during movement, and prevents operational errors or safety hazards caused by the shaking of the drive frame 8.

[0030] For better performance, the clamping piece 5 is connected to the middle of the drive gear 7, and the toothed plate 9 has a through hole 19 inside, through which the clamping piece 5 passes. The movement of the clamping piece 5 and the toothed plate 9 does not interfere with each other.

[0031] For better performance, a lever 20 is provided on the outer side of the bottom of the main body rod 1. The lever 20 can be used to adjust or lock the opening and closing state of the clamp 5.

[0032] For better results, a pointer 21 is provided on the top outer side of the clip 5. The pointer 21 can provide visual feedback during the operation and more accurately determine the opening and closing state of the clip 5.

[0033] When using this invention, hold the operating handle 3, utilizing its anti-slip texture to ensure a stable grip. Pass one end of the grounding wire through the connecting ring 4, ensuring the grounding wire is securely attached to the hook body 2. The operating handle 3 moves the main body rod 1 and hook body 2, hooking the hook body 2 onto the upper side of the wire. The drive mechanism moves the clamping plates 5, using the clamping plates 5 on both sides to tightly hold the wire, preventing the hook body 2 from falling off the upper side of the wire.

[0034] Furthermore, the drive mechanism is preferably used as follows: when the drive mechanism is in the initial position, the clamping piece 5 is in the open state, and the orientation of the leaf plate 15 is not consistent with that of the through groove 16, and the rotating shaft 11 is located inside the main body rod 1. The hook 2 is hung on the upper side of the wire by the operating handle, and the wire enters between the two clamping pieces 5 through the hook 2. The operating handle 3 is rotated (at this time, the lever 20 can be used as a support point, and the thumb can be pressed on the outside of the lever 20 to facilitate the movement of the operating handle 3), and the operating handle 3 drives the rotating shaft 11 to rotate until the orientation of the leaf plate 15 is consistent with that of the through groove 16. The pointer 21 can be used to provide auxiliary pointing function. At this time, under the action of the compression spring 14, the compression spring 14 pushes the top block 12, pushing the rotating shaft 11 out of the outside of the main body rod 1 through the through groove 16. The through groove 16 drives the drive frame 8 to move down through the connecting rod 10, and then drives the drive gear 7 to rotate through the toothed plate 9, so that the clamping piece 5 rotates around the hinge shaft 6, thereby firmly clamping the wire. To prevent the rotating shaft 11 from retracting into the main body rod 1 due to external force, the operating handle 3 can be rotated to align the leaf plate 15 with the through slot 16. When it is necessary to remove the device from the outside of the wire, the operating handle 3 is moved into the main body rod 1, and the rotating shaft 11 drives the drive frame 8 to reset via the connecting rod 10, thereby opening the clamp 5.

[0035] This utility model features convenient operation, stable clamping, and effectively improves the safety of power construction.
