Problems solved by technology

The double thread or multi-thread developed on the basis of the traditional single thread has the advantages of fast forward and fast rewind, and the speed will be at least twice as fast, but the double thread or multi-thread also has its own disadvantages. When the helix angle is increased, when the threaded connection is stressed or vibrated, the locking will be unreliable due to the reduction of the self-locking force, resulting in a decrease in the reliability of the tool with double or multiple threads.

Embodiment Construction

[0041] Such as Figure 1-14 The anti-loosening thread assembly shown is characterized in that it includes: an external threaded element 1 with an external thread, and a threaded element 2 with a thread that is adapted to the external threaded element, wherein the external threaded element 1 can be connected with the external thread The engagement of the thread moves relative to the threaded element, and the blocking element 3 arranged outside the external threaded element has a protrusion 31 on the inside of the blocking element, and there is a gap between the protrusion of the blocking element and the external threaded element. Under normal circumstances, the protrusion of the blocking element and the external threaded element The externally threaded components do not touch, and will not affect the normal use of the threaded components. When the externally threaded components are tilted under force, the externally threaded components contact the protrusions of the blocking ele...

Abstract

The invention discloses an anti-loosening thread assembly which is characterized in that the anti-loosening thread assembly comprises an external thread element provided with external threads, a thread element adaptive to the external thread element and provided with threads, and a stop element arranged on the exterior of the external thread element, wherein the external thread element can move relative to the thread element through the engagement between the external threads and the threads; a bulge is formed on the inner side of the stop element; a gap is formed between the bulge and the external thread element; and when the external thread element is inclined due to stress, friction is generated between the external thread element and the stop element to exert an anti-loosening effect.

Description

technical field [0001] The invention relates to a threaded assembly, more specifically to an anti-loosening threaded assembly. Background technique [0002] Threaded connection is a very widely used connection method, which can be applied to various connections and fixing tools, such as various types of G clamps, F clamps, pliers, double-ended wrenches, and wrenches. The double thread or multi-thread developed on the basis of the traditional single thread has the advantages of fast forward and fast rewind, and the speed will be at least twice as fast, but the double thread or multi-thread also has its own disadvantages. When the helix angle is increased, when the threaded connection is subjected to force or vibration, the locking will be unreliable due to the reduction of the self-locking force, which will result in a decrease in the reliability of the tool with double or multiple threads. How to solve the above problems simply and conveniently has become a difficult proble...
