DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: an electric grounding bolt for electric power engineering, comprising a grounding electrode body 1, a grounding assembly 200 for grounding is installed on the outer side of the grounding electrode body 1, and a connecting assembly 300 for connecting the grounding assembly 200 with the grounding electrode body 1 is installed on the outer side of the grounding electrode body 1; through the coordinated use of the grounding assembly 200 and the connecting assembly 300 on the outer side of the grounding electrode body 1, the processing difficulty can be reduced while the stability of the bolt connection can be effectively guaranteed, so that the processing process can be easy to implement, and at the same time, the connecting piece can be limited after the threaded connection, so that it is not easy to detach from the grounding bolt, thereby effectively maintaining the effectiveness of the connection, which is conducive to wide promotion, thereby effectively improving the practicality of the electric grounding bolt for electric power engineering.

[0024] In this embodiment, the connecting component 300 is a structure used to connect the grounding component 200 with the grounding electrode body 1 and can maintain the effectiveness of the connection.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the connecting assembly 300 includes a screw 301 threadedly connected to the left side of the grounding electrode body 1, a limiting member 302 fixed to the right end of the screw 301, a sleeve 303 fixed to the right side of the grounding electrode body 1, a connecting hole 304 opened at the top of the sleeve 303 and connected to the inside of the sleeve 303, a limiting hole 305 opened at the top of the sleeve 303 and connected to the inside of the connecting hole 304, a cover plate 306 fixed to the top of the sleeve 303 and covering the top of the limiting hole 305, a sliding plate 307 slidably connected to the inner side of the limiting hole 305, a spring 308 fixed between the top of the sliding plate 307 and the bottom of the cover plate 306, a plug-in block 309 fixed to the bottom of the sliding plate 307, and a plug-in slot 310 opened on the outer side of the limiting member 302.

[0026] It should be noted that an adjustment hole 311 connected to the inside of the connecting hole 304 is opened on the right side of the sleeve 303, and an adjustment groove 312 is opened on the right side of the plug-in block 309. The position of the adjustment hole 311 corresponds to the position of the adjustment groove 312, and the distance from the top of the adjustment groove 312 to the top of the adjustment hole 311 is greater than the depth of the plug-in groove 310. Specifically, a tool such as an Allen wrench or a plum blossom screwdriver is inserted into the inner side of the adjustment hole 311, and the end is inserted into the inner side of the adjustment groove 312, and then moved upward, so that the plug-in block 309 can be driven to detach from the inner side of the plug-in groove 310, and the screw 301 can be turned normally to rotate it out.

[0027] In addition, an internal threaded hole for threaded connection of the screw 301 is opened on the left side of the grounding electrode body 1, so that the screw 301 can be threadedly connected to the inner side of the internal threaded hole, the outer side of the right end of the limit member 302 is arc-shaped, the bottom of the left side of the plug-in block 309 is an inclined surface, and the bottom end of the plug-in block 309 is arc-shaped, so that the right end of the limit member 302 can normally push the plug-in block 309 to move upward through the inclined surface of the plug-in block 309.

[0028] At the same time, the inner diameter of the limiting hole 305 is larger than the inner diameter of the connecting hole 304 , and the plug-in block 309 is located inside the connecting hole 304 , so that the sliding plate 307 can slide normally inside the limiting hole 305 and can limit the plug-in block 309 .

[0029] In addition, the plug-in slot 310 is opened in a ring shape on the outer side of the limit piece 302, and the plug-in block 309 can be plugged into the inner side of the plug-in slot 310. The ring-shaped setting allows the plug-in block 309 to be easily inserted, and the fit limit between the inner wall of the plug-in slot 310 and the outer side of the plug-in block 309 can limit the limit piece 302, so that the screw 301 cannot move in a straight line. Specifically, when the screw 301 rotates, it will move in a straight line under the thrust of the outer thread, and after being limited by the plug-in block 309, the screw 301 cannot move in a normal straight line, so that the screw 301 cannot move according to the rotation, which plays an effective limiting role.

[0030] In this embodiment, the grounding assembly 200 is a structure for grounding in a conductive manner.

[0031] like Figure 1 As shown, the grounding assembly 200 includes a conductive ring 201 sleeved on the outside of a screw 301 , a wire 202 fixedly mounted on the top of the conductive ring 201 , and a gasket 203 sleeved on the outside of the screw 301 .

[0032] It should be noted that the right side of the conductive ring 201 is in contact with the left side of the grounding electrode body 1, the left side of the conductive ring 201 is in contact with the right side of the gasket 203, and the left side of the gasket 203 is in contact with the outer side of the left end of the screw 301, so that the screw 301 can exert an extrusion and limiting effect on the conductive ring 201 through the gasket 203, so that the conductive ring 201 can continue to fit with the outer side of the grounding electrode body 1.

[0033] The working principle of the above embodiment is:

[0034] When grounding, the gasket 203 and the conductive ring 201 are both sleeved on the outside of the screw 301, and the screw 301 is rotated to make it connected with the inner thread of the grounding electrode body 1, so that the limit piece 302 moves to the inner side of the sleeve 303. Under the action of the continuous rotation and movement of the screw 301, the conductive ring 201 will abut against the left side of the grounding electrode body 1, and the right end of the limit piece 302 will push the plug-in block 309 to move upward, so that the spring 308 is compressed. Under the elastic force recovery action of the spring 308, the plug-in block 309 is pushed to be plugged into the inner side of the plug-in slot 310 through the sliding plate 307, thereby realizing the threaded connection limit and the card connection limit at the same time. At this time, when the screw 301 wants to rotate and disengage, the fitting limit between the inner wall of the plug-in slot 310 and the plug-in block 309 will make the screw 301 unable to move, so that the screw 301 is not easy to disengage, and the effectiveness of the connection can be maintained for a long time.

[0035] Compared with the prior art, the power grounding bolt for power engineering, through the coordinated use of the grounding component 200 on the outside of the grounding electrode body 1 and the connecting component 300, can reduce the difficulty of processing while effectively ensuring the stability of the bolt connection, so that the processing process can be easy to implement. At the same time, it can also limit the connecting part after the threaded connection, so that it is not easy to detach from the grounding bolt, thereby effectively maintaining the effectiveness of the connection, which is conducive to wide promotion, thereby effectively improving the practicability of the power grounding bolt for power engineering, and solving the problem that although the existing power grounding bolt for power engineering can greatly improve the effectiveness of the connection, the overall processing technology is difficult and not conducive to implementation.

In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
