Description

Self-adaptation check screw connection structure
Technical Field
The invention belongs to the technical field of fastener connection, and relates to a self-adaptive anti-loosening screw connection structure.
Background
The anti-loosening type of screw connection is various, and the anti-loosening type comprises a mechanical locking type with split pin limiting, metal wire penetrating and stop washers, a free rotating type with spring washers, elastic washers, double nuts, fastening nuts and compression face teeth, a bonding type with coating adhesives, a punching point riveting type with thread punching points, base punching riveting and stud pier riveting, and an effective torque type with nylon rings and nylon inserts. The basic design idea is that the screwing-up is not performed or performed for a plurality of times, the more reliable the limiting is, the more difficult the screwing-up is, the screwing-up can damage the base body, the high-low temperature tolerance is not performed, and the unlimited times of repeated use can not be realized.
The traditional screw connection can deal with the conditions of dislocation, deflection, end surface nonparallel and the like of a base body hole, the two surfaces of the gasket, the screw and the base body can be in large-area contact by virtue of plastic deformation of the flat gasket, and the limitation of use times also exists.
In order to improve the anti-loosening reusability of the screw and the performance of the screw adapting to the base body, and the convenience of use, the integrity of the mechanism and the environmental suitability, a connecting structure which can automatically adapt to the conditions of base body hole dislocation, deflection, end surface nonparallel and the like and can prevent loosening after connection needs to be designed.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a self-adaptive anti-loosening screw connecting structure which can solve the problems of screw deflection, insufficient pressing area and crushing of a base body caused by poor coaxiality of a base body connecting hole, non-parallel end faces and the like and can prevent the screw from rotating automatically in a loosening direction.
The purpose of the invention is realized as follows:
a self-adaptive anti-loosening screw connecting structure comprises a nut and a screw, wherein a screw pair is formed to tension two base bodies, the self-adaptive anti-loosening screw connecting structure further comprises a cover plate, a nut washer, a screw washer, a connecting shaft and a return spring, the cover plate is arranged outside the base body and on one side of the nut, cover plate teeth are circumferentially arranged at one end, opposite to the nut, of the cover plate, a limiting boss is axially arranged in the middle of the cover plate and extends towards the direction of the nut, the nut comprises a limiting portion and a cylindrical portion, nut teeth are arranged at one end, opposite to the cover plate, of the limiting portion and meshed with the cover plate teeth, when the nut teeth and the cover plate teeth are meshed, the nut teeth and the cover plate teeth can only rotate towards the screwing direction of the screw, a limiting protrusion is arranged at the top of the nut limiting portion and matched with a groove of the base body to limit circumferential rotation of the nut, the nut washer is sleeved outside the screw, the nut washer and the nut limiting portion are in spherical surface contact with the screw head, the automatic adjustment and adaptation base body is characterized in that a screw driver groove is formed in the head of the screw, the screw driver is inserted into the screw driver groove to adjust the screw, a notch is formed in the tail of the screw and matched with a limiting boss of the cover plate to drive the cover plate to rotate synchronously, the return spring is sleeved on the connecting shaft, the connecting shaft and the return spring are integrally sleeved in the screw, the return spring is axially limited through the connecting shaft and the screw, and after the connecting shaft is sleeved in the screw, the tail of the screw is tightly connected with the cover plate;
when the screw is adjusted, the screwdriver is inserted into the screwdriver groove and simultaneously jacks into the connecting shaft, when the end face a of the connecting shaft jacks into the connecting shaft to be level with the bottom of the screwdriver groove, the cover plate teeth and the nut teeth are disengaged, the limiting boss of the cover plate does not disengage from the notch at the tail part of the screw at the moment, the screw can be screwed or unscrewed, after the screw is adjusted in place, the screwdriver is withdrawn, the connecting shaft enables the cover plate teeth and the nut teeth to be re-occluded by means of the spring force of the return spring, and the screw cannot rotate automatically in the unscrewing direction.
