Problems solved by technology

Bolts are combined with nuts through threads, or combined with workpieces through threads. Due to processing reasons and the influence of physical and chemical factors in the working environment, this rigid combination is an unstable combination, so it sometimes loosens.
People often adopt the method of combining caps, or adding washers and spring washers, or punching holes on the bolts, and positioning them through pins. These methods are labor-intensive and time-consuming, sometimes unreliable, and cause some unexpected problems. ACCIDENT

Abstract

The invention discloses a self-locking check bolt. The bolt comprises a bolt head, a bolt rod, a check disk and self-locking ejecting rods, wherein ejecting rod screw holes are formed in the bolt head; the self-locking ejecting rods are mounted in the ejecting rod screw holes; the bolt rod is arranged at the bottom of the bolt head and is sleeved with the check disk; ejecting rod positioning holes are formed in the check disk; and bottom ends of the self-locking ejecting rods penetrate through the ejecting rod positioning holes. The bolt can realize the self-locking check effect in various environments and is simple in structure, high in production efficiency, convenient to operate, high in universality and beneficial to market promotion and application.

Description

【Technical field】 [0001] The invention relates to the technical field of bolt processing, in particular to the technical field of an anti-loosening self-locking bolt. 【Background technique】 [0002] Bolt Mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw with a cylindrical body with external threads, which needs to be matched with a nut to fasten and connect two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. Bolts are combined with nuts through threads, or combined with workpieces through threads. Due to processing reasons and the influence of physical and chemical factors in the working environment, this rigid combination is an unstable combination, so it sometimes loosens. People often adopt the method of combining caps, or adding washers and spring washers, or p...
