Outside, one end of the jam plate is rotationally connected with lock, and the other end of jam plate is equipped with integrally formed handle, is leaned on the jam plate
One end of nearly lock is equipped with crescent moon locked groove and self-locking mechanism, and the described one end of crescent moon locked groove away from handle is equipped with and locks mouth.
As a kind of optimal technical scheme of the utility model, the self-locking mechanism includes sliding groove and is set with what can be slided
The fixture block being placed in sliding groove, the sliding groove is arranged on jam plate close to locking at the position of mouth, close on the sliding groove
One end of crescent moon locked groove is connected with crescent moon locked groove, and the fixture block sets resilient between one end and sliding groove away from crescent moon locked groove
Spring, the other end of the fixture block are extended in crescent moon locked groove.
As a kind of optimal technical scheme of the utility model, circle is equipped with close to the one end side for locking mouth on the fixture block
Arc sliding surface.
As a kind of optimal technical scheme of the utility model, pushing block is additionally provided with the fixture block.
The beneficial effects of the utility model are：
1st, the utility model is simple in structure, easy to use, and a flap that can cover mounting hole is set on lock,
So that crescent lock can hide mounting hole when mounted, the effect that can reach beautiful at the same time can also be to the screw in mounting hole
Protected, the corrosion to screw when there was dampness in the air is reduced, so as to extend the service life of crescent lock；
2nd, originally it is that utility model is also provided with self-locking mechanism on lock, can effectively avoids existing when between two fan door and windows
Gap is acted on situation about easily being pried open when sash deforms from outside by external force, so as to improve anti-theft feature and safety

Embodiment
The utility model row is further described presently in connection with attached drawing.
As shown in Figure 1, a kind of crescent lock, including lock 1, flap 2 and jam plate 3, the opposite end of the lock 1 are set respectively
There is mounting hole 4, be equipped with shaft 5 between two mounting holes 4 on lock 1, the flap 2 is connected in the outer surface of lock 1 simultaneously
Two mounting holes 4 can be covered, corresponds on the flap 2 at the position of shaft 5 and is equipped with axis hole 6, when the flap 2 is clamped
When on lock 1 outside one end extension shaft outlet hole 5 of shaft 5, one end of the jam plate 3 is connected on lock 1, and the jam plate
3 can rotate along shaft 5, and one end away from shaft 5 is equipped with handle 7 integrally formed with jam plate 3 on the jam plate 3, described
One end on jam plate 3 close to lock 1 is equipped with crescent moon locked groove 8 and self-locking mechanism, one end of remote handle 7 on the crescent moon locked groove 8
Equipped with locking mouth 9；
The self-locking mechanism includes sliding groove 10 and the fixture block 11 being arranged in sliding groove 10 that can be slided, the slip
Groove 10 is arranged on jam plate 3 close to locking at the position of mouth 9, close to one end of crescent moon locked groove 8 and crescent moon on the sliding groove 10
Locked groove 8 is connected, and return spring 12 is equipped between one end and sliding groove 10 away from crescent moon locked groove 8 on the fixture block 11, described
Extended on fixture block 11 close to one end of crescent moon locked groove 8 in crescent moon locked groove 8；
On the fixture block 11 circular sliding surface 13 is equipped with close to the one end side for locking mouth 9；
The pushing block 14 easy to which fixture block 11 is promoted is additionally provided with the fixture block 11.
A kind of crescent lock, which further includes lock and is arranged at, latches the latch hook that upper and crescent moon locked groove 8 matches, institute
