[0035] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the present invention provides a temporary grounding wire quick grounding device, the purpose of which is to fix the grounding wire conductive rod 2 by fastening the locking cover 4, and then connect the fastening device 7 to the fastening locking cover 4 by threads. If the user needs to set up the grounding wire, he only needs to clamp the fastening device 7 on the grounding device 8, and embed the head of the grounding wire conductive rod 2 into the conductive rod embedding hole 1 to achieve a quick and simple grounding operation. At the same time, the service life of the equipment can be extended by pressing the block 404 and the positioning component 710.

[0039] One of the main features of the temporary grounding wire quick grounding device is that it includes a grounding device 8, a grounding wire conductive rod 2 and a fastening lock cover 4 for limiting the grounding wire conductive rod 2. A fastening device 7 is connected to the bottom of the fastening lock cover 4 through a thread. The fastening device 7 can fix the head of the grounding wire conductive rod 2, and then the fastening device 7 can be fixed to the fastening lock cover 4 through a threaded connection. Then, when the user needs to set up the grounding wire, the fastening device 7 only needs to be plugged into the top of the grounding device 8. A fastening spring 6 is arranged between the fastening device 7 and the fastening lock cover 4. The fastening spring 6 can make the conductive rod and the grounding device 8 in close contact. Both ends of the fastening spring 6 A rubber gasket 5 is installed, which has a buffering and pressing effect. A five-proof lock socket 3 is opened on the upper side wall of the grounding device 8, and the five-proof lock socket 3 can prevent malicious misoperation. A conductive rod embedding hole 1 is opened on the upper surface of the grounding device 8 to prevent the grounding wire conductive rod 2 from rotating. The conductive rod embedding hole 1 is designed to allow the head of the conductive rod to be inserted. At the same time, because the conductive rod embedding hole 1 is a D-shaped structure and a sliding groove 901 is provided in the conductive rod embedding hole 1, the conductive rod embedding hole 1 can also play a limiting role to prevent the conductive rod from rotating after being inserted into the grounding device 8. A five-proof lock socket 3 is also opened on one end side wall of the grounding wire conductive rod 2.

[0040] The assembly method of the grounding device for grounding wire is very simple. It only needs to insert the conductive rod 2 of the grounding wire into the fastening device 7, and then insert the gasket 5 and the fastening spring 6 from the tail of the conductive rod, and finally tighten the lock cover. When in use, insert the head of the conductive rod into the conductive rod embedding hole 1 of the D-shaped structure on the grounding device 8, and then press the fastening device 7 downward. After the fastening spring 6 is compressed, rotate the locking buckle 10 to reliably fasten the conductive rod to the grounding device 8. Finally, the electrical five-proof lock is connected in series to prevent misoperation. Compared with traditional equipment, this device is convenient and fast, easy to disassemble and install, and can greatly reduce the operation time. In addition, the contact surface between the grounding end of the grounding wire and the grounding device 8 is larger, which improves the safety performance of the grounding wire.

[0041] Specifically, a conductive rod through hole 402 is provided on the fastening lock cover 4 , and a diameter value of the conductive rod through hole 402 is greater than a diameter value of a side wall of the other end of the grounding wire conductive rod 2 .

[0042] When the device is used, the fastening spring 6 is directly fixed into the fastening device 7. Since there is a conductive rod through hole 402 in the middle of the fastening lock cover 4, whose diameter is slightly larger than the diameter of the tail of the conductive rod, the tail of the conductive rod can be allowed to pass through. Then the fastening spring 6 can fully clamp the conductive rod so that it will not move easily.

[0043] The fastening device 7 is provided with a plurality of locking buckles 10 at equal intervals at one end away from the fastening lock cover 4. The locking buckles 10 are of an L-shaped structure. When the user needs to complete the operation of setting up the grounding wire, the user can directly place the assembled fastening device 7 on the grounding device 8, and then press the fastening device 7 downward. After the fastening spring 6 is compressed, the locking buckle 10 is rotated to reliably fasten the conductive rod to the grounding device 8, and finally the electrical five-protection lock is connected in series to prevent misoperation.

[0044] like Figure 4 As shown, the second main feature of the temporary grounding wire quick grounding device is that an embedding groove 801 is provided at the upper end of the grounding device 8, and an auxiliary anti-rotation component 9 for secondary limiting the grounding wire conductive rod 2 is installed in the embedding groove 801. The auxiliary anti-rotation component 9 can position, guide and insert the conductive rod inserted into the conductive rod embedding hole 1 and prevent rotation. The auxiliary anti-rotation component 9 includes two symmetrically arranged sliding clamps 902 and two connecting tooth blocks 903. The two sliding clamps 902 are both located in the sliding groove 901, and the two connecting tooth blocks 903 are respectively connected to the two sliding clamps 902. The side wall of the connecting tooth block 903 is meshed with a rotating gear 904, and the outer wall of the rotating gear 904 is meshed with a movable tooth block 905 on the side away from the connecting tooth block 903.

[0045] The specific operation of the auxiliary anti-rotation component 9, which plays a role in positioning and guiding the insertion when the conductive rod is inserted, is as follows: when the guide rod is inserted into the conductive rod embedding hole 1, the two sliding clamps 902 located in the sliding groove 901 will be pushed away, that is, the two sliding clamps 902 move away from each other along the sliding groove 901 (the user can install a tension spring between the two sliding clamps 902 so that after the conductive rod is pulled out, the two sliding clamps 902 can automatically reset, which is convenient for subsequent operations), until the two sliding clamps 902 are respectively attached to the side walls of the conductive rod, and when the two sliding clamps 902 slide, the connecting tooth block 903 will also slide, and at this time the rotating gear 904 will be driven to rotate by engagement, and the rotating rotating gear 904 will engage and drive the movable tooth block 905 to move in the opposite direction of the connecting tooth block 903.

[0046] like Figure 5 As shown, further, the movable tooth block 905 is installed with a limiting cover 906 on the side surface away from the rotating gear 904, and a limiting groove 907 is provided in the limiting groove 907. A lifting block 909 is provided in the limiting groove 907 and is slidably connected to the limiting cover 906. A lifting spring 908 is fixedly installed between the lifting block 909 and the limiting cover 906. The lifting block 909 is connected to a protective rod 910 extending into the conductive rod embedding hole 1 through a rotating shaft.

[0047] The specific operation of the auxiliary anti-rotation component 9 to prevent rotation when the conductive rod is inserted is as follows: when the movable tooth block 905 moves in the direction opposite to the connecting tooth block 903, that is, it moves towards the direction close to the conductive rod at the same time, the protective rod 910 will gradually penetrate into the pole embedding hole 1. At this time, the limiting groove 907 gradually approaches the conductive rod, and the protective rod 910 that gradually penetrates into the pole embedding hole 1 will slide along the limiting cover 906 with the lifting block 909, so that the lifting spring 908 is compressed until the protective rod 910 is stuck to the conductive rod. At this time, the position of the conductive rod is fully restricted and will no longer rotate easily.

[0048] like Figure 7 As shown, the third main feature of the temporary grounding wire quick grounding device is that a rotating disk 401 is provided on the upper surface of the fastening lock cover 4, and a conductive rod through hole 402 is also provided on the rotating disk 401 and the pressing block 404, so that the insertion of the conductive rod will not be affected, and a pressing block 404 is provided in the fastening lock cover 4, and the pressing block 404 can press the gasket 5 at one end of the fastening spring 6, so that the fastening spring 6 can be further compressed, and the rotating disk 401 is installed with a rotating cylinder 403 on the side surface close to the pressing block 404, and the The outer wall of the rotating cylinder 403 is connected to a rotating ring 405 through a thread, and the outer wall of the rotating ring 405 is slidably connected to a limit ring 407. The limit ring 407 can be stuck in the limit ring groove 406, so that the rotating ring 405 can slide up and down when the rotating disk 401 rotates, avoiding the situation that the rotating ring 405 rotates together with the rotating cylinder 403. The inner wall of the fastening lock cover 4 is provided with a limit ring groove 406 for limiting the limit ring 407, and the rotating ring 405 is connected to the pressing block 404 through a connecting rod 408.

[0049] The rotating disk 401 can further press the fastening spring 6 when rotating, so that the fastening spring 6 will not fail and cause insufficient contact between the conductive rod and the grounding device 8. During operation, the user can rotate the rotating disk 401, and then the rotating cylinder 403 rotates together, so that the rotating ring 405 is driven to rotate. At the same time, due to the existence of the limiting ring 407, the rotating ring 405 will be led by the limiting ring 407 to slide downward along the limiting ring slot 406, and then the pressing block 404 also moves therewith so that the gasket 5 at one end of the fastening spring 6 is tightly pressed.

[0050] like Figure 6 and Figure 8As shown, further, a plurality of mounting grooves 701 are arranged at equal intervals in the fastening device 7, a positioning assembly 710 is installed in the mounting groove 701, and an auxiliary mounting groove 702 is arranged below the mounting groove 701, the positioning assembly 710 includes a press positioning cover 704, the press positioning cover 704 can play the purpose of clamping the conductive rod, the press positioning cover 704 is located in the mounting groove 701, and a press spring is fixedly installed between the press positioning cover 704 and the fastening device 7. Spring 706, the pressing and positioning cover 704 is provided with a plurality of rubber inclined blocks 705 on the surface of one side away from the pressing spring 706, and a plurality of inclined sliding blocks 707 are provided in the pressing and positioning cover 704. The side wall of the inclined sliding block 707 is slidably connected with a sliding table 708, and the sliding table 708 can slide along the inclined sliding block 707. At the same time, because the cross-section of the inclined sliding block 707 is a right-angled trapezoidal structure, the sliding table 708 will slide towards the pressing spring 706 with the sliding connecting rod 709 when sliding.

[0051] The positioning component 710 can lock the position of the conductive rod so that the position of the conductive rod will not change easily during the insertion operation, which facilitates the subsequent operation of inserting the conductive rod into the grounding device 8 without spending a lot of time on positioning. At the same time, after the positioning component 710 locks the position of the conductive rod, it can fully ensure that the position of the conductive rod will not be loose, etc. Even if the fastening spring 6 fails, the contact between the conductive rod and the grounding device 8 will not change significantly. It is very practical. The steps for the positioning component 710 to achieve the positioning operation are as follows: when the conductive rod is inserted, the pressing positioning cover 704 will be pushed by the inserted conductive rod component and slide along the mounting groove 701, and the pressing spring 706 will also be squeezed. At this time, the elastic force of the spring increases, that is, the position of the conductive rod will be locked by the pressing positioning cover 704, and a number of rubber bevels 705 are provided on the pressing positioning cover 704, so the conductive rod cannot be easily rotated.

[0052] like Figure 8 As shown, a pushing block 711 slidably connected to the fastening device 7 is provided in the auxiliary installation groove 702, a pushing spring 712 is fixedly installed between the pushing block 711 and the fastening device 7, and the pushing block 711 is connected to the sliding platform 708 via a sliding connecting rod 709. The pushing block 711 is provided with an auxiliary positioning block 703 at the end away from the fastening device 7, and the auxiliary positioning block 703 is slidably connected to the fastening device 7.

[0053] The positioning assembly 710 can fully clamp the conductive rod so that it will not easily become loose after being inserted into the grounding device 8. During operation, once the positioning cover 704 is pressed to slide along the mounting groove 701, the sliding link 709 is led by the sliding platform 708 to slide in the direction of the pressing spring 706, and the push spring 712 will be compressed. At the same time, the push block 711 will also be led by the sliding link 709 to slide in the direction of the pressing spring 706, so that the auxiliary positioning block 703 slides toward the auxiliary mounting groove 702 until it is in contact with the push block 711 again. At this time, when the user inserts the conductive rod, the auxiliary positioning block 703 can play a limiting role to fix its position.
