Description

Novel anti-theft anti-loose bolt and nut set

Technical Field

The invention belongs to the technical field of bolts and nuts, and particularly relates to a novel anti-theft anti-loose bolt and nut suit.

Background

The anti-loose and anti-theft method for bolt and nut used today mainly adopts the method of increasing friction force to achieve the purpose of preventing loosening, and there are some common anti-loose and anti-theft methods for preventing loosening and anti-theft by changing their structures, such as split pins, series steel wires and stop washers. This way the disassembly is inconvenient.

Disclosure of Invention

Aiming at the situation, in order to overcome the defects of the prior art, the invention provides a novel anti-theft and anti-loose bolt and nut set, an elastic locking sheet is added to prevent the nut from loosening and loosing reversely, a good effect is achieved, great cost is not required to be added, the structure is ingenious, and the problem of poor bolt and nut effect in the current market is reliably and effectively solved.

The technical scheme adopted by the invention is as follows: the invention discloses a novel anti-theft anti-loose bolt and nut set, which comprises a bolt, a nut and an elastic locking sheet, wherein the elastic locking sheet is arranged in the nut, and the bolt is meshed and connected with the nut; the bolt comprises a head and a screw, the screw is arranged on the bottom wall of the head, locking grooves are formed in the circumferential side wall of the screw at uniform intervals, the head is arranged in a hexagonal shape, and the screw is cylindrical.

Further, elasticity locking piece includes gasket, wedge pole, bayonet socket and flexure strip, the bayonet socket symmetry is located on the gasket, the wedge pole is located on the gasket diapire and is located bayonet socket department, the flexure strip is located on the wedge pole.

Further, the nut comprises a nut body, a pad groove and a clamping groove, the pad groove is formed in the upper end of the nut body, the gasket is clamped in the pad groove, and the clamping groove is symmetrically formed in the inner side wall of the nut body.

The invention with the structure has the following beneficial effects: this scheme is a novel theftproof check bolt nut suit, increases an elasticity lock plate and prevents that the nut from reversing laxity and locking, has reached fine effect, need not increase very big cost, and the structure is ingenious, has reliably effectively solved the poor problem of bolt nut effect on the existing market.

The nut comprises a bolt 1, a bolt 2, a nut 3, an elastic locking sheet 4, a head 5, a screw rod 6, a gasket 7, a wedge-shaped rod 8, a bayonet 9, an elastic sheet 10, a nut body 11, a gasket groove 12, a clamping groove 13 and a locking groove.

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-4, the novel anti-theft and anti-loose bolt and nut set of the invention comprises a bolt 1, a nut 2 and an elastic locking piece 3, wherein the elastic locking piece 3 is arranged in the nut 2, and the bolt 1 is meshed with the nut 2; bolt 1 includes head 4 and screw rod 5, screw rod 5 is located on the 4 diapalls of head, even interval arrangement is equipped with locking groove 13 on the circumference lateral wall of screw rod 5, head 4 is the hexagon setting, screw rod 5 is cylindrical.

Elasticity locking piece 3 includes gasket 6, wedge pole 7, bayonet socket 8 and

flexure strip

9, 8 symmetries of bayonet socket are located on the gasket 6, wedge pole 7 is located on the 6 diapalls of gasket and is located 8 departments of bayonet socket, flexure strip 9 is located on wedge pole 7.

The nut 2 comprises a nut body 10, a pad groove 11 and a clamping groove 12, the pad groove 11 is formed in the upper end of the nut body 10, the gasket 6 is clamped in the pad groove 11, and the clamping groove 12 is symmetrically formed in the inner side wall of the nut body 10.

When the device is used specifically, a user aligns the wedge rod 7 with the clamping groove 12 and inserts the wedge rod, the gasket 6 is placed in the pad groove 11, the screw rod 5 is aligned with the center of the nut 2 and rotates, the elastic piece 9 can be inserted into the locking groove 13 of the screw rod 5, when the nut 2 is screwed in clockwise, the elastic piece 9 can be pressed into the clamping groove 12 on the nut 2 by the threads on the bolt 1, the screwing-in of the nut 2 cannot be influenced, if the nut 2 is screwed out in the opposite direction, the locking piece can be abutted against the locking groove 13 on the screw rod 5, and therefore the nut 2 is prevented from being screwed off.
