Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-8, the latch hinge includes a first component 1 and a second component 2, the first component 1 and the second component 2 are hinged together, the first component 1 and the second component 2 are respectively welded on two adjacent plates and are fixed by rotating and matching, the first component 1 includes a first sleeve 11, a fixed core column 13 is welded inside the first sleeve 11, a first spiral body 12 is formed at one end of the first sleeve 11, the first spiral body 12 is wrapped outside the fixed core column 13, the second component 2 includes a second sleeve 21, a second spiral body 22 is formed at one end of the second sleeve 21, and the first spiral body 12 and the second spiral body 22 are buckled together.
