Description

Technical Field

[0001] The utility model specifically relates to the technical field of bolts, in particular to a novel bolt and nut anti-loosening component. Background Art

[0002] Bolt: A mechanical part, a cylindrical threaded fastener that is matched with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which must be matched with a nut to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

[0003] China Utility Model Publication No. CN 211174958 U discloses a high-strength anti-loosening bolt, comprising a bolt, a nut and a reverse bolt, wherein the outer wall of the bolt has a thread, a circular groove is formed at the right end of the bolt, the inner wall of the circular groove has a reverse thread, a long groove is formed in contact with the outer wall of the circular groove at the right end of the bolt, the nut is threadedly connected to the outer wall of the bolt, and the reverse bolt is threadedly connected to the right side of the bolt;

[0004] The above-mentioned high-strength anti-loosening bolt is achieved by opening a circular groove at the center of the bolt head, and processing a reverse thread on the inner wall of the circular groove. Four long grooves are also opened on the bolt, and the long grooves are connected to the circular groove. When the nut is installed on the bolt, the reverse bolt is installed in the circular groove of the threaded head. However, the reverse bolt can still be pulled out relatively easily after being inserted into the circular groove, and thus it is easy to disengage. For this reason, we provide a new type of bolt and nut anti-loosening assembly, which pushes the clamp head through a spring, and the clamp head will be clamped with the locking hole of the external threaded tube, so that it cannot be loosened. After connecting the buckle cap, the clamp head is protected so that it cannot leak out when the buckle cap is not opened. When disassembly is required, the clamp head is pushed in, and the external threaded tube can be unscrewed to complete locking and opening. It is more convenient to use and effectively compensates for the above-mentioned problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model adopts a spring to push the clamp head to move, and the clamp head will be clamped with the locking hole on the threaded locking tube. After the threaded locking tube is threadedly connected to the external threaded tube, the locking is completed. The inner support rod supports the spring, which is convenient for the clamp head to be pushed, and ensures that the clamp head can also play a layer of anti-slip effect after the threaded connection.
