Problems solved by technology

[0003] When the mechanical equipment is running, mechanical vibration will inevitably occur. Long-term mechanical vibration will cause the bolts to shake, resulting in thread wear, making the fastening effect of the bolts worse, affecting the working performance and stability of the mechanical equipment, especially affecting some precision parts. The machining accuracy of the equipment may also cause bolts to escape from the threaded holes, which may cause mechanical failure

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0026] This embodiment relates to an anti-loosening bolt, including: a screw rod 1 and a nut 2 . It should be noted that the anti-loosening bolt also includes an anti-loosening component 3 . The anti-loosening part 3 is assembled on the screw rod 1 and inserted into the nut 2 . The anti-loosening part 3 is used to press against the nut 2 when the nut 2 is loose, so as to avoid the phenomenon of loosening between the nut 2 and the screw rod 1 .

[0027] Specifically, a slot 21 is provided on the side of the ...

Abstract

The invention discloses an anti-loosening bolt, and relates to the technical field of bolts. The anti-loosening bolt comprises a screw rod and a nut. The anti-loosening bolt further comprises an anti-loosening piece which is assembled on the screw rod and inserted with the nut and used for abutting against the nut when the nut is loosened so as to avoid the loosening phenomenon. The side, close tothe anti-loosening piece, of the nut is provided with a slot, and the side, far away from the anti-loosening piece, of the nut is provided with a threaded part matched with the screw rod. The side, close to the slot, of the anti-loosening piece is provided with an inserting part, the inserting part is used for inserted into the slot for assembling, and the side, far away from the inserting part,of the anti-loosening piece is provided with a rotating head used for screwing the anti-loosening piece. Due to the adoption of the anti-loosening bolt of the technical scheme, through the arranged anti-loosening piece, when the nut is loosened, the nut is extruded to one side of the screw rod to enable the inner wall of the nut to abut against the screw rod, so that the nut moves more and more tightly, and the anti-loosening bolt has the advantages of being simple in structure, ingenious in design, convenient to disassemble and assemble and good in anti-loosening effect.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to an anti-loosening bolt. Background technique [0002] A bolt is a type of fastener consisting of a bolt head and a screw rod (a cylinder with external threads), which is used to fasten and connect two mechanical parts with through holes. If the bolt is unscrewed, the two parts can be separated, so the bolt connection is a detachable connection, which is widely used in the fields of plate fastening, equipment assembly, and part connection. [0003] When the mechanical equipment is running, mechanical vibration will inevitably occur. Long-term mechanical vibration will cause the bolts to shake, resulting in thread wear, making the fastening effect of the bolts worse, affecting the working performance and stability of the mechanical equipment, especially affecting some precision parts. The machining accuracy of the equipment may also cause bolts to escape from the threaded holes, whi...
