Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

the first embodiment is as follows:

as shown in fig. 1 and 2, the rotary lock body includes a lock shell 11, one end of the lock shell 11 is hinged with a trigger 15, the other end of the lock shell 11 is hinged with a rotary tongue 13 matched with the trigger 15, and an elastic reset device 18 is arranged between the trigger 15 and the rotary tongue 13; the trigger 15 and the rotating tongue 13 are respectively hinged with the lock shell 11 through a pin shaft 17 with a threaded hole; the upper part and the lower part of the rotating tongue 13 are respectively provided with a rear locking hole 12 and a front locking hole 14; the trigger 15 is provided with a trigger bulge 20, and the rotating tongue 13 is provided with a groove 21 matched with the trigger bulge 20.

As shown in fig. 3, in this embodiment, when manufacturing and installing, the elastic resetting device 18 is a series connection integrated spring, two ends of the elastic resetting device 18 are respectively sleeved on the pin shafts 17 with threaded holes of the trigger 15 and the rotating tongue 13, and are limited by the spring constraint points 16; after the trigger 15 is installed on the pin shaft 17 with the threaded hole, the axial limiting is carried out through a gasket 19, and the outer side of the gasket 19 is fixed through riveting.
