Description

Technical Field

[0001] The utility model relates to the technical field of grounding tools, in particular to a puncturing grounding tool. Background Technique

[0002] Grounding of electrical components is very important, which can protect electrical appliances and personal safety, and improve electrical safety. Component grounding is frequently carried out in grounding tests required in laboratories and outdoor power stations. Conventional grounding methods are relatively complex and cannot ensure true grounding. With the rapid development of society, the types of grounding tools have gradually increased, and their functions have been continuously improved.

[0003] For example, the patent document with the authorization announcement number CN213916764U discloses a grounding clamp tool, which includes a bracket, a suction cup slidable up and down on the bracket, and a connecting rod structure for driving the suction cup to move up and down. The suction cup is detachably adsorbed and connected to the workpiece; a clamp head is provided on the bracket. When the suction cup is adsorbed on the workpiece, the bottom end of the clamp head is communicated with the workpiece. The bracket is also provided with an adjusting member for adjusting the position of the clamp head up and down; the clamp head is connected with a wire electrically connected to the ground. The grounding clamp tool of the utility model can fix the clamp head on the workpiece, keep the workpiece grounded continuously, avoid welding sparking caused by the inability of the clamp head to be grounded continuously, and avoid the generation of pits and burnt black spots at the contact points between the workpiece and the iron platform, so as to avoid affecting the appearance and quality of the product and reduce subsequent repair work.

[0004] However, there are problems that the current component grounding tools have numerous steps, often cannot ensure true grounding, consume bolts and other consumables during the operation process, are inconvenient for disassembly, inspection and repair, and have poor practicability. Therefore, we propose a puncturing grounding tool to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a puncturing grounding tool to solve the problems in the existing grounding tools mentioned in the above background technique, that is, the current component grounding tools have numerous steps, often cannot ensure true grounding, consume bolts and other consumables during the operation process, are inconvenient for disassembly, inspection and repair, and have poor practicability.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A puncturing grounding tool, including a magnet and a protective cover. An installation groove is opened inside the magnet. Card slots are opened on the front and rear side walls at the bottom end of the installation groove. It also includes a metal conductive puncturing tooth and a fixing mechanism. Limiting blocks are fixedly installed on both the front and rear sides of the metal conductive puncturing tooth. A handle is fixedly installed at the upper end of the metal conductive puncturing tooth. A threaded cylinder is installed inside the upper surface of the magnet. An annular groove is opened inside the magnet. Limiting card seats are opened on both the left and right sides of the installation groove. A sliding groove is opened on the outside of the limiting card seat;

[0007] The protective cover is installed at the upper end of the magnet. Fixed blocks are installed on the lower surface of the protective cover. Finger grooves are formed on both the left and right sides of the upper surface of the protective cover, and a groove is formed on the upper surface of the protective cover.

[0008] Preferably, the connection mode of the protective cover and the magnet through the threaded cylinder is a threaded connection.

[0009] Preferably, the metal conductive puncturing teeth rotate in the magnet through the annular groove.

[0010] Preferably, the fixing mechanism includes a stop rod, a fixed seat and a screw. The stop rod is slidably installed inside the chute. A fixed seat is installed on the upper surface of the stop rod, and a screw is installed inside the fixed seat in a threaded manner.

[0011] Preferably, the stop rod and the magnet form a front-back sliding structure through the chute, the fixed seat and the screw.

[0012] Preferably, the metal conductive puncturing teeth and the magnet form a disassembly structure through the limit block, the stop rod, the fixed seat and the screw.

[0013] Preferably, a metal conductive connection block is connected to the rear side of the metal conductive puncturing teeth. A metal conductive connection band is connected to the rear side of the metal conductive connection block. A grounding wire connection ring is fixedly installed on the rear side of the metal conductive connection band.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: This puncturing grounding tooling;

[0015] 1. The upper and lower magnets adsorb and clamp the frame. Compared with bolt fasteners, there is consumption and the reuse rate is high. In the reliability laboratory, for the grounding test, due to the length of the grounding wire, two people may be required to cooperate. In contrast, only one person is required to complete the operation in this solution, which can save costs and manpower;

[0016] 2. The detachable metal conductive puncturing teeth are provided, which is convenient for quickly disassembling, replacing and overhauling the metal conductive puncturing teeth. Compared with the previous solution that requires cumbersome steps such as grinding and screwing, this solution only needs to twist the upper and lower sides of the frame a few times to complete, improving efficiency. The dust-proof cover plays a role in preventing dust and avoiding aging caused by dust accumulation;

[0017] 3. There will be dust when grinding the insulating layer, which is harmful to the health of the operator after inhalation. When using a grinding rod to grind the insulating layer, there may be a situation where the grinding is not thorough, resulting in poor grounding performance. In this patent, since the puncturing teeth puncture the insulating layer, this situation can be effectively avoided, improving the performance and protecting the environment.
