Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution for an explosion-proof static electricity release instrument: an explosion-proof static electricity release instrument, including a base 1, a column 2 fixedly connected to the top of the base 1, an explosion-proof touch ball 3 installed on the top of the column 2, and a convenient mechanism 5 installed at the bottom of the base 1. The convenient mechanism 5 is used to facilitate the movement of the explosion-proof static electricity release instrument;

[0026] The convenient mechanism 5 includes a universal wheel 509, a locking component and an annular frame component;

[0027] The locking component is used to lock or unlock the movement of the universal wheel 509;

[0028] The universal wheel 509 in the unlocked state is used to assist the explosion-proof static electricity release instrument in moving;

[0029] The annular frame component is used to fix the position of the explosion-proof static electricity release instrument.

[0030] Please refer specifically to Figure 2 , the annular frame component includes a moving rod 501, a spring 502 and an annular frame 503;

[0031] The moving rod 501 is slidably connected up and down to the end of the base 1, the annular frame 503 is fixedly connected to the bottom of the moving rod 501, the spring 502 is sleeved on the outer wall of the moving rod 501, and both ends of the spring 502 are fixedly connected to the base 1 and the annular frame 503 respectively.

[0032] In this embodiment: By moving the annular frame 503 downward with the hand, the annular frame 503 in the downward movement state drives the moving rod 501 to descend, and at the same time stretches the spring 502. The annular frame 503 is lowered to the position in contact with the ground, thereby fixing the position of the explosion-proof static electricity release instrument.

[0033] Please refer specifically to Figure 3 , the locking assembly includes a stud 504, a through slot 505, an "L"-shaped connecting rod 506, a fixed seat 507, a through hole 508, a connecting shaft 5010, a gear 5011 and a tooth block 5012;

[0034] The stud 504 is rotatably installed at one end of the outer wall of the column 2. The through slot 505 is opened at the top of the base 1 and completely penetrates. The vertical part of the "L"-shaped connecting rod 506 is slidably connected inside the through slot 505. The fixed seat 507 is fixedly connected to the bottom of the base 1. The through hole 508 is opened on the outer wall of the fixed seat 507 and completely penetrates. The connecting shaft 5010 is rotatably connected to the inner wall of the fixed seat 507. The gear 5011 is assembled at one end of the outer wall of the connecting shaft 5010, and the universal wheel 509 is installed at the other end of the outer wall of the connecting shaft 5010. The tooth block 5012 is fixedly connected to the bent part of the "L"-shaped connecting rod 506.

[0035] In this embodiment: By rotating the stud 504 with the hand, the stud 504 in the rotating state drives the vertical part of the "L"-shaped connecting rod 506 to move inward along the track of the through slot 505. Then, the bent part of the "L"-shaped connecting rod 506 drives the tooth block 5012 to move in the direction close to the gear 5011 along the track of the through hole 508. Then, the tooth block 5012 meshes with the tooth groove of the gear 5011, and the meshed tooth block 5012 and gear 5011 lock the connecting shaft 5010. Then, the connecting shaft 5010 in the locked state cannot assist the universal wheel 509 to rotate. Furthermore, the universal wheel 509 in the locked state makes the explosion-proof static electricity release instrument unable to move randomly anymore.

[0036] Please refer specifically to Figure 3 , the stud 504 is threadedly connected to one end of the "L"-shaped connecting rod 506, and the bent part of the "L"-shaped connecting rod 506 is slidably connected inside the through hole 508.

[0037] In this embodiment: The rotating stud 504 drives the vertical part of the "L"-shaped connecting rod 506 to move inward along the track of the through slot 505.

[0038] Please refer specifically to Figure 4 , the tooth block 5012 meshes with the tooth groove of the gear 5011, and the meshed tooth block 5012 and gear 5011 are used to lock and fix the rotation of the universal wheel 509.

[0039] In this embodiment: The tooth block 5012 is engaged with the tooth groove of the gear 5011. Then, the engaged tooth block 5012 and gear 5011 lock the connecting shaft 5010, and the locked connecting shaft 5010 cannot assist the universal wheel 509 to rotate.

[0040] Please refer specifically to Figure 2 , the descending annular frame 503 is used to stretch the spring 502, and the reset spring 502 is used to drive the moving rod 501 and the annular frame 503 to move upward.

[0041] In this embodiment: The annular frame 503 is moved downward by hand. Then, the downward-moving annular frame 503 drives the moving rod 501 to move downward, and at the same time stretches the spring 502, and the annular frame 503 is lowered to a position in contact with the ground.

[0042] Please refer specifically to Figure 1 , a handle 4 for hand-holding is installed at the other end of the outer wall of the column 2, and a bolt hole 6 for tightening a bolt is provided at the top of the convenient mechanism 5.

[0043] In this embodiment: A bolt is threadedly connected to the bolt hole 6 inside the annular frame 503. Then, the tightened bolt fixes the annular frame 503 to the ground, and thus the installation of the explosion-proof static electricity release instrument is completed.

[0044] Working principle: When the explosion-proof static electricity release instrument needs to be installed in a place, first, the handle 4 is held by hand to pull the column 2. Then, the universal wheel 509 rotatably installed at the bottom of the base 1 assists the explosion-proof static electricity release instrument to move, facilitating the operator to bring the explosion-proof static electricity release instrument to any area where installation is required through the universal wheel 509. When the movement of the explosion-proof static electricity release instrument is completed, at this time, the stud 504 is rotated by hand, and the rotating stud 504 drives the vertical part of the "L"-shaped connecting rod 506 to move inward along the track of the through groove 505. Then, the bent part of the "L"-shaped connecting rod 506 drives the tooth block 5012 to move in the direction close to the gear 5011 along the track of the through hole 508. Then, the tooth block 5012 is engaged with the tooth groove of the gear 5011, and the engaged tooth block 5012 and gear 5011 lock the connecting shaft 5010. Then, the locked connecting shaft 5010 cannot assist the universal wheel 509 to rotate. Furthermore, the locked universal wheel 509 makes the explosion-proof static electricity release instrument unable to move freely. At this time, the annular frame 503 is moved downward by hand. Then, the downward-moving annular frame 503 drives the moving rod 501 to move downward, and at the same time stretches the spring 502, and the annular frame 503 is lowered to a position in contact with the ground. Then, a bolt is threadedly connected to the bolt hole 6 inside the annular frame 503. Then, the tightened bolt fixes the annular frame 503 to the ground, and thus the installation of the explosion-proof static electricity release instrument is completed.

[0045] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
