Description

Technical Field

[0001] This utility model relates to the field of power safety protection technology, and in particular to a grounding clamp that is easy to attach and detach. Background Technology

[0002] In the inspection and maintenance of power systems, grounding clamps are key tools to ensure the safety of workers. Their main function is to reliably connect equipment or lines to the earth, forming short-circuit protection and preventing electric shock accidents caused by sudden power surges. However, existing grounding clamps have many shortcomings: most require two-handed operation, which reduces operational flexibility in high-altitude or confined spaces, increasing the difficulty of operation and safety hazards; moreover, the contact between the clamp and the conductor is mostly a rigid connection, which makes it difficult to guarantee a stable clamping force when there are slight differences in conductor size, potentially leading to unreliable grounding and affecting operational safety. Therefore, those skilled in the art provide a grounding clamp that is easy to attach and detach to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a convenient grounding clamp for attaching and detaching.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A convenient grounding clamp includes an insulating rod, one end of which is connected to a connecting tube, and one end of the connecting tube is fixedly connected to a first clamp body. A grounding wire is fixedly connected to the first clamp body. A sliding groove I is provided on one side of the first clamp body, and a second clamp body is slidably connected in the sliding groove I. An operating handle is fixedly connected to the other end of the insulating rod. The operating handle is provided with a driving component that can be operated with one hand to drive the opening and closing of the first clamp and the second clamp. The driving component includes a grip that is rotatably disposed in a groove opened on one side of the operating handle and a transmission cavity opened inside the operating handle. A rack is slidably disposed in the transmission cavity. The second clamp is provided with a compression component on one side of the notch. The compression component includes a compression block that is slidably disposed in a relief groove opened on one side of the second clamp and a second spring that abuts against the compression block.

[0005] As a further embodiment of this utility model, the drive assembly further includes a drive gear, which is fixedly sleeved on the rotating shaft of the operating handle. A transmission rod is rotatably connected inside the transmission cavity. A driven gear and a drive gear are fixedly sleeved on the transmission rod. The driven gear meshes with the drive gear, and the drive gear meshes with the rack.

[0006] As a further embodiment of this utility model, the top inner wall and the bottom inner wall of the transmission cavity are provided with sliding grooves II, and the top and bottom of the rack are fixedly connected with sliders, and the two sliders extend into the corresponding sliding grooves II and slide in cooperation with the sliding grooves II.

[0007] As a further embodiment of this utility model, a connecting rod is fixedly connected to one side of the first clamp body inside the slide groove I. The connecting rod slides to the inside of the insulating rod and is fixedly connected to a connecting ring. The outer wall of the connecting ring is slidably connected to the inner wall of the insulating rod. One end of the connecting ring is rotatably connected to an extension rod. One end of the extension rod slides to the inside of the transmission cavity and is fixedly connected to the rack.

[0008] As a further embodiment of this utility model, one end of the insulating rod extends into the interior of the connecting pipe and is rotatably connected to the connecting pipe.

[0009] As a further embodiment of this utility model, a first spring for resetting is sleeved on the connecting rod, and the two ends of the first spring abut against one side of the second clamp and one end of the insulating rod, respectively.

Detailed Implementation

[0016] 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. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0017] Reference Figures 1-4 A convenient grounding clamp includes an insulating rod 1, one end of which is connected to a connecting tube 2. A first clamping body 3 is fixedly connected to one end of the connecting tube 2, and a grounding wire 18 is fixedly connected to the first clamping body 3. A sliding groove I is formed on one side of the first clamping body 3, and a second clamping body 4 is slidably connected within the sliding groove I. An operating handle 5 is fixedly connected to the other end of the insulating rod 1. The operating handle 5 is equipped with a drive assembly that can be operated with one hand to open and close the first clamping body 3 and the second clamping body 4. The drive assembly includes a grip 6 rotatably disposed within a groove formed on one side of the operating handle 5 and a transmission cavity formed inside the operating handle 5, in which a rack 14 is slidably disposed. A pressing assembly is provided on the side of the second clamping body 4 located at the recess. The pressing assembly includes a pressing block 16 slidably disposed within a clearance groove formed on one side of the second clamping body 4 and a second spring 17 abutting against the pressing block 16.

[0018] The drive assembly also includes a drive gear 11, which is fixedly mounted on the rotating shaft of the operating handle 5. A transmission rod is rotatably connected inside the transmission cavity, and a driven gear 12 and a drive gear 13 are fixedly mounted on the transmission rod. The driven gear 12 meshes with the drive gear 11, and the drive gear 13 meshes with the rack 14. Slide grooves II are formed on both the top and bottom inner walls of the transmission cavity. Slide blocks are fixedly connected to the top and bottom of the rack 14, extending into their respective slide grooves II and slidingly engaging with them. The engagement of the slide blocks with the slide grooves II ensures stable sliding of the rack 14 within the transmission cavity, preventing rack 14 from shifting and affecting transmission accuracy, thereby ensuring the smooth opening and closing of the first clamp 3 and the second clamp 4.

[0019] A connecting rod 7 is fixedly connected to one side of the first clamp 3 inside the slide groove I. The connecting rod 7 slides into the interior of the insulating rod 1 and is fixedly connected to a connecting ring 9. The outer wall of the connecting ring 9 is slidably connected to the inner wall of the insulating rod 1. One end of the connecting ring 9 is rotatably connected to an extension rod 10. One end of the extension rod 10 slides into the interior of the transmission cavity and is fixedly connected to the rack 14. One end of the insulating rod 1 extends into the interior of the connecting tube 2 and is rotatably connected to the connecting tube 2. A first spring 8 for resetting is sleeved on the connecting rod 7. The two ends of the first spring 8 abut against one side of the second clamp 4 and one end of the insulating rod 1, respectively. When the drive assembly moves the second clamp 4, the first spring 8 deforms. After the driving force is removed, the first spring 8 can drive the second clamp 4 to automatically reset, facilitating the next operation.

[0020] Two sliding rods 15 are symmetrically fixed to one inner wall of the clearance groove. The extrusion block 16 has clearance holes corresponding to the sliding rods 15. The two sliding rods 15 extend into the corresponding clearance holes. Two second springs 17 are respectively sleeved on the corresponding sliding rods 15, with their ends abutting against one side of the extrusion block 16 and one inner wall of the clearance groove. The sliding rods 15 guide the sliding of the extrusion block 16, preventing it from shifting during movement and ensuring stable contact between the extrusion block 16 and the conductor. The elastic force of the second springs 17 ensures a tight fit between the extrusion block 16 and the conductor, enhancing the reliability of the clamping. A limiting block 401 is fixedly connected to one side of the second clamping body 4. A limiting groove 301 corresponding to the limiting block 401 is provided on the side of the first clamping body 3 near the second clamping body 4. When the first clamping body 3 and the second clamping body 4 are combined, the limiting block 401 is inserted into the limiting groove 301. The cooperation between the limiting block 401 and the limiting groove 301 can improve the stability when the first clamping body 3 and the second clamping body 4 are combined, and prevent them from shaking relative to each other during the clamping process.

[0021] Working principle: First, the grounding wire 18 is installed on the first clamp 3. Then, the operator holds the operating handle 5 and grip 6. When the grip force increases, the grip 6 rotates around its axis, driving the drive gear 11 to rotate. The drive gear 11 meshes with the driven gear 12, thereby driving the driven gear 12 and the transmission rod to rotate. The rotation of the transmission rod causes the drive gear 13 to rotate synchronously. The drive gear 13 meshes with the rack 14, driving the rack 14 to slide within the transmission cavity. The sliding of the rack 14 drives the extension rod 10 to move. The extension rod 10 pushes the connecting ring 9 to slide within the insulating rod 1. The connecting ring 9 drives the connecting rod 7 to move. The connecting rod 7 then drives the second clamp 4 to slide within the slide groove I of the first clamp 3, realizing the opening and closing of the first clamp 3 and the second clamp 4. This process does not require the use of both hands, making it especially suitable for high-altitude operations or scenarios with limited space, reducing the difficulty of operation. When the conductor is clamped, the conductor squeezes the clamping block 16. The clamping block 16 slides on the slide rod 15 and compresses the second spring 17. The reaction force of the second spring 17 makes the clamping block 16 fit tightly against the conductor, ensuring good contact. After the operation is completed, the handle 6 is released, the first spring 8 returns to its original position and pushes the second clamp 4 back to its initial position, so that the first clamp 3 and the second clamp 4 are closed. The limiting block 401 is inserted into the limiting groove 301 to ensure structural stability.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
