Abstract

The invention relates to the technical field of bolts and nuts, in particular to a bolt and nut assembly; the bolt and nut assembly comprises a bolt head, a thread rod is arranged on the center of oneside of the bolt head, a nut body is in threaded connection to the thread rod, a round shell is arranged on one side of the nut body, a round block is arranged at one end of the thread rod, the roundblock is located in the round shell, a cylinder is arranged at one end of the round shell, an end cover is arranged at one end of the cylinder, a rectangular groove is formed in one end of the roundblock, a rectangular rod is arranged in the cylinder, the other end of the rectangular rod penetrates through one end of the round shell and extends to be arranged in the rectangular groove, a limiting plate is fixed to the rectangular rod in the cylinder, a second spring is arranged at the position, between the limiting plate and the end cover, of the rectangular rod in a sleeving manner, and a protection mechanism is arranged on the side face of the round shell. The bolt and nut assembly is reasonable in structure and convenient to operate, through matching of the rectangular rod and the rectangular groove, the nut body can be prevented from loosening, through a protection cover, the thread rod and the nut body are protected, the thread rod and the nut body are prevented from being corroded, and a user can conveniently use the assembly.

Description

technical field [0001] The invention relates to the technical field of bolts and nuts, in particular to a bolt and nut assembly. Background technique [0002] Bolts and nuts are mechanical parts, a type of fasteners consisting of a head and a screw (a cylinder with external threads), which need to be matched with nuts to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. But now when the bolt and nut assembly is connected, when it is used on the machine, the nut is easy to loosen, which makes the parts on the machine unstable. damage, for which we propose a bolt-nut assembly. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose a bolt and nut assembly in order to solve the disadvantages existing in the prior art. [0004] In order to achieve the above object, the pr...
