Locking bolt with built-in bidirectional adjusting mechanism

Abstract

The invention relates to the technical field of fastener self-locking, in particular to a locking bolt with a built-in bidirectional adjusting mechanism. The locking bolt comprises a bolt head and an external thread assembling rod. The locking bolt with the built-in bidirectional adjusting mechanism is composed of the bolt head and the external thread assembling rod, the external thread assembling rod is designed to be of a detachable split structure, the specification and size of the locking bolt can be freely changed according to needs, and the application range is very wide; an internal thread telescopic adjusting mechanism can be controlled to stretch out and draw back in the external thread assembling rod through a screw adjusting device, and therefore the external diameter of the external thread assembling rod is changed, and the self-locking performance is improved while assembling is facilitated; through lateral and top elastic extrusion, the assembling firmness and stability are greatly improved; and an external thread assembling plate is connected with arc external thread assembling plates and a fixed cylinder by inserting a high-strength reset elastic piece into a flat insertion hole so that quick assembling and disassembling can be achieved, and the later maintenance and use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of fastener self-locking, in particular to a locking bolt with a built-in bidirectional adjustment mechanism. Background technique [0002] A bolt is 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 form of connection is also called bolt connection. The operation strategies of bolt has: electronic product, engineering goods, digital product, power equipment, dynamo-electric engineering goods. Ships, vehicles, water conservancy projects, even also use bolts in chemical experiments, are widely used. [0003] At present, most of the bolts on the market are simple in structure and cannot be adjusted. They need to cooperate with the external threaded assembly rod and the bolt head to complete the fixed limit. It is mainly assembl...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved locking bolt with a built-in two-way adjustment mechanism is provided to solve the problem that most of the bolts currently on the market have simple structures, cannot be adjusted, and have limited friction coefficients. The anti-loosening performance and safety factor are not high, the orientation of the opening position is insufficient, and it cannot be disassembled and replaced, resulting in a very limited scope of application.
