A screw hole for removal is provided in the axial direction of the outer end surface of the removal column 2031.
After the bolt body 1 and the lock nut 2 are locked and fixed, the locking anti-falling block 203 is clamped into the locking groove 131 on the locking block 13, and at this time, if the bolt body 1 is screwed out, the locking anti-falling block 203 is required to be separated from the locking block 13. When the locking anti-drop block 203 is separated, the dismounting head 201 is unscrewed firstly, the second spring 202 is poured out, then a screw rod is screwed into the threaded hole in the dismounting column 2031 (the external thread on the screw rod is matched with the internal thread of the threaded hole in the dismounting column 2031), then the locking anti-drop block 203 is pulled out outwards, and the locking anti-drop block 203 can be separated from the locking block 13.
The outer wall of the locking nut 2 is provided with an installation platform 3, and the installation platform 3 is provided with a plurality of installation holes. The mounting table 3 facilitates the mounting and fixing of the nut to the object to be used.
When the bolt is used, the locking nut 2 is fixed inside the equipment, the bolt body 1 is arranged on the outer side of the equipment, then the bolt body 1 penetrates through the fixed object, and then the bolt body 1 is fixedly connected with the locking nut 2. The locking step of the bolt assembly is described in detail below:
referring to fig. 3 to 5, the threaded connection portion 11 of the bolt body 1 is first screwed into the screw hole 21, the hexagonal bolt head 12 is rotated to move the threaded connection portion 11 toward the bottom of the screw hole 21, and the locking block 13 is made to contact with the stopper 222. The hexagonal bolt head 12 continues to rotate, the locking block 13 gradually presses the stop block 222 downwards, the stop block 222 overcomes the spring force and moves towards the limiting hole 22, and the locking anti-falling block 203 always abuts against the outer wall of the stop block 222 in the downward movement process of the stop block 222. When the click sound is heard, the locking anti-drop block 203 is clamped in the locking groove 131 on the locking block 13, at the moment, the bottom surface of the threaded connecting part 11 just abuts against the bottom surface of the screw hole 21, and the whole bolt body 1 and the locking nut 2 are assembled.
When the bolt body 1 needs to be disassembled, the disassembling head 201 is unscrewed firstly, the second spring 202 is poured out, then a screw rod is screwed into the threaded hole in the disassembling column 2031, and then the locking anti-falling block 203 is pulled out outwards, so that the locking anti-falling block 203 is separated from the locking block 13. When the screw rod is loosened, the screw rod is pulled outwards, the locking anti-falling block 203 is enabled to tightly abut against the stepped hole surface of the mounting hole 20, and then the screw rod is rotated reversely, so that the screw rod can be loosened and detached.
After the bolt body 1 is detached, the stop block 222 is restored to the initial position under the action of the spring force, then the second spring 202 is arranged in the bolt body 1, the mounting and detaching head 201 is mounted, and the bolt assembly can be repeatedly used.
After the bolt body 1 is locked and fixed with the lock nut 2, if the phenomenon that the bolt body 1 is forcibly unscrewed by a lawbreaker occurs, because the locking prevents the magnet arranged on the block 203, the magnet is always adsorbed in the locking groove 131 of the locking block 13, when the bolt body 1 is forcibly rotated reversely, because the locking prevents the one end of the block 203 from being stretched in the mounting hole 20, one end is adsorbed in the locking groove 131, therefore, the locking prevents the block 203 from being blocked in the mounting hole 20 and the locking groove 131, the second spring 202 is mostly destroyed, and the bolt body 1 can not be separated from the lock nut 2. The bolt assembly can also be used in occasions with large vibration, and the separation between the bolt body 1 and the locking nut 2 is avoided.
It should be emphasized that, when the bolt assembly of the present invention is used, it is not suitable to expose the lock nut 2 to the outside for use, because if the detaching head 201 of the lock nut 2 is exposed to the outside, the theft-proof structure of the present invention can be unlocked only by a lawbreaker detaching the detaching head 201. Therefore, the invention is suitable for the use occasions that the lock nut 2 is arranged inside an object and the bolt body 1 is arranged outside the object, for example, when an insulator or power transmission equipment is fixed on the outer wall of an outdoor transformer, the lock nut 2 is arranged inside the transformer, the bolt body 1 is arranged outside the transformer, and the insulator or the power transmission equipment is fixed. Or when the outdoor electric control cabinet is used, the locking nut 2 is fixed on the inner wall of the electric control cabinet, and the bolt body 1 is arranged outside the electric control cabinet, so that a bridge frame or other devices matched with the electric control cabinet to be used are fixed on the outer wall of the electric control cabinet.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
