What is the tolerance range of precision screws?
In view of the deficiencies in the prior art, the purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a detachable rivet to solve the problems raised in the above-mentioned background technology. Guangdong Yueluo Hardware Industry Co., Ltd. is easy to use, easy to operate, and has good stability. , high reliability.
Bolt and nut fasteners are widely used fasteners, which can be used in mechanical products as well as daily craft industrial products, such as plastic packaging boxes, plastic packaging boxes, paper packaging boxes, paper packaging boxes, etc. . When bolt and nut fasteners are used in daily craft industrial products, the requirements for the degree of tightening are generally low, but they are required to be easy to install and use. When assembling the existing bolt and nut fasteners, it is generally necessary to manually twist the bolt or the nut several times until the two are tightened, which takes time and causes inconvenience in daily life. Lower, it is manifested as an increase in labor costs. SUMMARY OF THE INVENTION The main purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a bolt and nut fastener that is easy to install in view of the above-mentioned deficiencies of the prior art. The two are assembled and fastened, which is convenient to use.
Self-locking nuts generally rely on friction. The principle is to press the embossed teeth into the preset holes of the sheet metal. Generally, the diameter of the square preset holes is slightly smaller than that of the rivet nut. The nut is connected with the locking mechanism. When the nut is tightened, the locking mechanism locks the ruler body, and the ruler frame cannot move freely to achieve the purpose of locking; when the nut is loosened, the locking mechanism disengages the ruler body, and the ruler frame edge body movement
