[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1 - 3, A quick-detachable positioning bolt, comprising a screw rod 1 and a screw head 11. A hexagonal block 19 is fixedly arranged at the top of the screw rod 1. A hexagonal groove is penetrated and opened at the top of the screw head 11. The hexagonal block 19 is inserted into the hexagonal groove. First chutes are evenly opened on the outer side wall of the screw head 11. Second chutes are evenly opened at the top of the screw head 11. The second chutes communicate with the first chutes. Slots are evenly opened on the outer side wall of the hexagonal block 19. The slots correspond to the first chutes. A threaded hole is opened at the top of the hexagonal block 19. A protective component is placed on the outer side wall of the screw head 11. A fixing component is placed in the first chutes. The protective component includes a cover 12. A groove is opened at the top of the cover 12. An annular fixing groove is opened on the inner side wall of the groove. A counterbore is penetrated and opened at the bottom of the groove. A sealing lining 17 is fixedly arranged on the inner side wall of the cover 12. A sealing plug 13 is slidably arranged in the groove. A snap ring 15 is fixedly arranged on the outer side wall of the sealing plug 13. The snap ring 15 is clamped in the annular fixing groove. The sealing plug 13 is clamped in the groove of the cover 12 through the snap ring 15. The cross bolt 16 is protected against rust by the sealing plug 13 and the sealing lining 17, so as to ensure that the cross bolt 16 can be normally disassembled later. An easy-pull groove 14 is opened at the top of the sealing plug 13. A cross bolt 16 is rotatably arranged in the counterbore. The cover 12 is sleeved on the top of the outer side wall of the screw head 11. The inner side wall of the sealing lining 17 is fitted with the outer side wall of the screw head 11. The bottom of the cross bolt 16 penetrates the counterbore of the cover 12 and is screwed with the threaded hole of the screw head 11. The fixing component includes a clamping block 18. A clamping groove 2 is opened at the top of the clamping block 18. The clamping block 18 is slidably arranged in the first chutes and the second chutes of the screw head 11. One end of the clamping block 18 close to the screw head 11 is inserted into the slot of the hexagonal block 19. The hexagonal block 19 is inserted into the hexagonal groove of the screw head 11 through the clamping block 18, so that the screw head 11, the hexagonal block 19 and the screw rod 1 form a bolt. The outer side wall of the clamping block 18 is flush with the outer side wall of the screw head 11 and is fitted with the inner side wall of the sealing lining 17.
[0020] Working principle: The hexagonal block 19 is inserted into the hexagonal groove of the screw head 11 through the clamping block 18, so that the screw head 11, the hexagonal block 19 and the screw rod 1 form a bolt. The cover 12 is fixed to the top of the outer wall of the screw head 11 through the cross bolt 16. The cross bolt 16 is protected against rust by the sealing plug 13 and the sealing lining 17, so as to ensure that the cross bolt 16 can be normally disassembled later. When the screw rod 1 is rusty and cannot be directly disassembled, the sealing plug 13 is pulled upward through the easy-pull groove 14 to be separated from the cover 12. At this time, after the cross bolt 16 is unscrewed, the cover 12 can be moved upward to be separated from the screw head 11. Then, a flat-blade screwdriver can be inserted into the card slot 2 and the clamping block 18 can be pushed outward to be separated from the slot of the screw head 11. Then, the screw head 11 can be moved upward to be separated from the hexagonal block 19. At this time, the externally positioned and fixed parts can be moved upward to be separated from the screw rod 1. Then, the lubricant can be relatively easily input into the connection gap between the screw rod 1 and the external threaded hole. At this time, the hexagonal block 19 is rotated by a wrench to drive the screw rod 1 to be screwed out of the external threaded hole, so as to achieve the rapid disassembly effect after the screw rod 1 is rusty.
