Problems solved by technology

[0004] 1. Tighten the pull rope for fixing the goods during work, but during operation, the goods will be displaced due to the vibration of the road surface, causing the pull rope to loosen. The looseness of the pull rope will cause the threaded parts on both sides of the turnbuckle to lose pre-tightening force. Make the turnbuckle and tie rod easy to separate, resulting in irreparable loss
[0005] 2. The thread of the turnbuckle bolt is prone to failure under high tension, especially the failure of the thread matching part

Abstract

The invention belongs to the technical field of bolts, and particularly relates to a bolt which comprises a pull rod and an adjusting shell. After a pull rope for fixing goods is tensioned, a gear adjusting plate is moved to enable one end of a clamping strip to be clamped in a corresponding annular ratchet on a ratchet wheel, at the moment, an adjusting swing plate is moved to drive an adjustingring to rotate, the adjusting ring drives the ratchet wheel through the clamping strip to rotate, the ratchet wheel drives an adjusting sleeve to rotate, the adjusting sleeve is rotated to drive two first nuts to rotate through the cooperation of a guide block and a guide groove, therefore, the two first nuts slide towards the side provided with a locking spring while rotating, and the locking spring is compressed. Pre-tightening force is generated through the compressed locking spring; and the problems that during operation, the goods is displaced due to vibration on the road surface, the pull rope is loosened, threaded matching parts on the two sides of a flower basket bolt lose pre-tightening force due to the loosening of the pull rope, the flower basket bolt and the pull rod are easilyseparated, and irreparable loss is caused are prevented.

Description

technical field [0001] The invention belongs to the technical field of bolts, in particular to a bolt. Background technique [0002] The turnbuckle bolt is composed of an adjusting rod with left and right-handed threads, a nut and a pull rod; the tension of the wire rope can be adjusted by using the lead screw to expand and contract. Components can be bundled during component transportation and loosened during installation and correction. [0003] However, the basket bolts have the following problems during use: [0004] 1. Tighten the pull rope for fixing the goods during work, but during operation, the goods will be displaced due to the vibration of the road surface, causing the pull rope to loosen. The looseness of the pull rope will cause the threaded parts on both sides of the turnbuckle to lose pre-tightening force. The turnbuckle bolt and the pull rod are easily separated, causing irreparable losses. [0005] 2. The thread of the turnbuckle bolt is prone to failure...
