Problems solved by technology

[0005] In the above-mentioned Patent Document 1, the invention arranges the clamping strips on the screw rod, and the clamping strips are clamped between the first nut and the second nut, so that the bolt group is self-locked and difficult to disassemble, but the number of clamping strips is too small and the vibration is frequent , the two clips do not have a good self-locking effect on the bolts, and they are easy to slip out

Embodiment approach 1

[0031] After the nut 3 is screwed onto the screw rod 1, turn the rotating handle 8 so that the rotating shaft 5 rotates, the rotating shaft 5 drives the ring block 6 to rotate, the semicircle block 7 rotates with the ring block 6, and the semicircle block 7 makes the guide rod 13 to rotate The outer side moves, and the guide rod 13 pushes the arc block 12 to move. When the arc block 12 moves to the outside, when the bar 15 touches the nut 3, the bar 15 rotates to both sides, and the bar 15 blocks the nut 3, and the nut 3. After being stuck, after utilizing the through hole of the pin to pass the screw head 2 and the passage of the rotating shaft 5, the pin is welded dead.

Embodiment approach 2

[0033] After the nut 3 is screwed onto the screw rod 1, turn the rotating handle 8 so that the rotating shaft 5 rotates, the rotating shaft 5 drives the ring block 6 to rotate, the semicircle block 7 rotates with the ring block 6, and the semicircle block 7 makes the guide rod 13 to rotate Moving outside, the guide rod 13 pushes the arc block 12 to move. When the arc block 12 moves to the outside, the rack 16 follows the arc block 12 and moves to the outside. When the rack 16 is pressed against the nut 3, the rack 16 As soon as the groove of the fixed block 14 moves inwardly, the tooth bar 16 moves to make the gear 17 rotate, and the gear 17 rotates to spread the clip bar 15 and be stuck in the thread of the nut 3, so that the nut 3 is stuck. After the nut 3 is stuck, use After the passing of the pin through the through hole of the screw head 2 and the turning shaft 5, the pin is welded dead.

Abstract

The invention belongs to the technical field of fixed members, and particularly relates to a self-locking bolt. The self-locking bolt comprises a screw, a screw head and a nut; the screw head is in adisk shape, and is provided with a through hole in the horizontal direction; the screw is a half-thread screw; the end, close to the screw head, of the screw is a smooth surface; the end, away from the screw head, of the screw is of a threaded structure; and the nut is matched with a bolt. A bolt set can be in self locking, a good anti-theft effect is achieved, two implementing manners are achieved for self locking of the nut, and a selective space is provided.

Description

technical field [0001] The invention belongs to the technical field of fixing components, in particular to a self-locking bolt. Background technique [0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. [0003] Ordinary nuts will loosen by themselves due to vibration and other reasons during use. In order to prevent this phenomenon, self-locking bolts were invented. The function of self-locking bolt is mainly anti-loosening, anti-vibration, and also has anti-theft effect. [0004] Patent document 1: A self-locking anti-theft bolt set, application number: 2017106220672 [0005] In the above-mentioned Patent Document 1...
