Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a mechanical fastener that prevents loosening, which can solve the problem that when connecting two through-hole parts, the existing bolts and nuts need to be used to fasten the connection. When fastening, it is necessary to find Working with bolts and nuts of the same specification is troublesome, the process is cumbersome and complicated, and there may be problems such as loosening during long-term fastening. It can realize the function of multiple limit locking between two through-hole parts. Bolts, Two nuts are combined into one, no need to look for matching fasteners, after the two through-hole parts are connected, they can be tightened multiple times, and will not loosen as time goes by, and the operation is simple

Abstract

The invention relates to a locking mechanical fastener comprising a fastener head device, a limiting device and a tightening device. The left end of the fastener head device is provided with the limiting device, and the tightening device is installed at the right end of the fastener head device. The locking mechanical fastener can solve the problem that the existing two through-hole parts need tobe fastened under matching of the existing bolts and nuts during connection, the bolts and the nuts of the same specification need to be found during fastening, the process is troublesome and complex,and loosening may be caused during long-term fastening. The locking mechanical fastener can achieve the function of multiple limiting locking between the two through-hole parts. The bolts and the nuts are combined into one, and a user does not need to find matched fasteners. After the two through-hole parts are connected, multiple limiting fastening is conducted, no loosening occurs as time goesby, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of mechanical fastener parts, in particular to a mechanical fastener for preventing loosening. Background technique [0002] Fasteners are mechanical parts used to connect and fasten parts. Fasteners are used in various industries that require connection and fastening. Among them, existing two through-hole parts need to be connected with existing bolts, The cooperation of nuts is used for fastening connection. When fastening, it is necessary to find bolts and nuts of the same specification for work. It is troublesome to find, the process is cumbersome and complicated, and loosening may occur during long-term fastening. Contents of the invention [0003] In order to solve the above problems, the present invention provides a mechanical fastener that prevents loosening, which can solve the problem that when connecting two through-hole parts, the existing bolts and nuts need to be used to fasten the connection...
