Problems solved by technology

However, the tension of the spring washer deteriorates over time
In addition, the limitation of the above structure is that the screw cannot be completely prevented from loosening under strong external impact.
Moreover, since additional work is necessary in the case of using welding or adhesives, it is time-consuming and expensive

Abstract

Disclosed herein is a loose preventing assembly including a bolt, a fastening member, and a pin-spring washer coupled between the bolt and the fastening member. The pin-spring washer includes a spring washer portion, a curved portion of which one end is connected to the spring washer portion to be curved upward and the other end is positioned in an inward direction of the spring washer portion, and a pin portion which extends in one direction from the other end of the curved portion tightens the bolt to couple the pin portion to an insertion groove formed in the bolt, thereby preventing the bolt and the fastening member from being loosened from each other.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of Korean Patent Application No. 10-2010-0112283 entitled "Anti-loosening Device" filed on November 11, 2010, which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to an anti-loosening device. Background technique [0004] Bolts and nuts are generally used to securely fasten building structures, machine parts, etc. [0005] As time goes by, the fastened bolt and nut assembly loosens due to external vibration or impact, thereby deteriorating the stability of mechanical parts and the like. In particular, in the case of a printed circuit board, which is grounded by a configuration in which screws ground circuit wiring and chassis (or boards), when the screws are loosened during use of the product, the product cannot be grounded to start. [0006] Therefore, in order to prevent the screws from loosening due to external vibration or i...
