It rises, latch hook 600 and lock body shell 100 separate automatically.
In addition, further including fixing screws 800,200 upper right side of lock gall shell is located at the latch hook and receives under channel 130
Side；
The latch hook receives 130 bottom end of channel to offer screw hole downwards, and 200 corresponding position of lock gall shell offers spiral shell
Hole, the lock gall shell 200 are fixedly installed in the latch hook by fixing screws 800 and receive 130 bottom end of channel.
Lock gall shell 200 is inserted into after lock body shell 100, is fixed with by fixing screws 800, makes the fixed knot of the two
Structure is located inside lock body shell 100, and after sealed, and fixing screws 800 can not be found from outside, makes lock body shell 200 and lock
Courage shell 200 is easily installed in production, while is also prevented from lock gall shell 200 and lock body shell 100 is detached in locked state,
It ensure that reliability of the lock in secure context.
In addition, the latch hook 600, which further includes the recess section 640 recess section 640, is opened in 600 body of rod of latch hook, institute
Recess section 640 is stated to be located between the constraint groove 630 and the main recess position；
Gap is formed between the recess section 640 and the confined channel 140, and the gap is towards the rotating dog 510.
Constraint groove 630 is used to latch hook 600 being constrained in confined channel, and the effect for opening up recess section 640 is to be conducive to latch hook
600 bounce, and after unlocking, latch hook 460 and lock body shell 100 are in opened condition.
In addition, 110 outer ring of lock gall inner casing offers annular groove, spacing block set, the lock are equipped in the annular groove
Courage shell 200 is equipped with pipe bit slice 250, and the pipe bit slice 250 is set in the annular groove, and the pipe bit slice 250 is constrained in institute
State lock gall shell 200；The pipe bit slice 250 is in 270 degree of circular arc sheets, and 250 outer edge of pipe bit slice is equipped with positioning protrusion
251；
It further includes and resets wind spring 260, the reset wind spring 260 is sheathed on the transmission protrusion 111, the reset wind spring
260 both ends are individually fixed in the transmission protrusion 111 and the lock body shell 100.
Pipe bit slice 250 is not rotated relative to lock body shell 100, therefore the stroke of the spacing block set of lock gall inner casing 110 is exactly ring
The remaining 90 degree of notches of shape slot；It after 90 degree of key turns, can not extract out, after resetting later, key could be extracted out, and this programme is passing
Reset wind spring 260 has been set in dynamic protrusion 111, after 90 degree of 111 rotation of transmission protrusion no longer in the case of stress, reset wind spring
260 natural elasticity can drive 110 reversing reset of lock gall inner casing, and lock core is in locking states always.
