When excessive, due to release sliding block be plastic part, lock tongue is metalwork, will cause release sliding block damage and can not normal return, this
When lock can not open, it will cause passenger that can not unlock safety belt.
Summary of the invention
The purpose of the utility model is to provide a kind of safety belt lock catch with long service life.
Purpose of the utility model is realized as follows:
A kind of safety belt lock catch, the lock include lock shell, latch and offer inserting for lock tongue insertion on shell
Entrance, the lock shell is interior to be equipped with groove profile seat, is equipped with button, lock bolt and the cunning being slidably arranged on groove profile seat in groove profile seat
Block is provided with a camber member on the sliding block, and the head of camber member is equipped with lock pin, and lock pin is set to the top of the lock bolt simultaneously
And the both ends of lock pin are erected at the two sides of the groove profile seat, and return bullet is additionally provided between the camber member and the rear end of the lock bolt
Spring；
Limiting device is provided with below the lock bolt, the limiting device includes at least one molding boss downwards,
For limiting the amount of movement of lock tongue insertion lock.
Further, the front end of the lock bolt is a tapered end bent downward, and one is offered in the middle part of lock bolt and supplies the bow
The through-hole that shape part passes through, in the two sides of the through-hole, the rear end thereof of lock bolt is assemblied in the groove profile seat boss forming,
And the rear end of lock bolt also forms spring base, one end of the return spring mounts elastically, the other end and the arch
Part connection.
Further, the lower end of the camber member is articulated with the sliding block, and the head of the upper end of camber member offers a ditch
Slot is equipped with lock pin in the groove.
Further, the left and right sides of the groove profile seat is offered for the guide groove mobile for the lock pin.
Further, the two sides of the button are all provided with fluted, the setting of the both ends of the lock pin in the groove, make by
It can be by the movement of the groove bands pendulum lock pin of two sides when pressing button.
Compared with the prior art, the utility model has prominent and beneficial technical effects that:
1. the utility model increases the boss structure for limiting lock tongue amount of movement on lock bolt, and in sliding block corresponding positions
It sets place and increases evacuation, the insertion displacement of lock tongue is limited.It can avoid passenger during lock tongue insertion wearing
After safety belt, avoid that it is excessively multipair passenger's wearing number in addition can be reduced as the damage caused by lock of lock tongue accident stress
Lock damages caused by inside, improves safety belt bulk life time.
2. corresponding position is provided with lock bolt and sliding block in insert port, when normal condition, lifted on the tapered end on the head of lock bolt, when
When lock tongue is inserted into insert port, the head of lock tongue pushes sliding block, so that tapered end pushing be made to block lock bolt.
3. lock tongue pushes sliding block inward movement, the camber member being connected with sliding block, bow can be pushed by the elastic force of rebound spring
Under spring force the pushing lock bolt by lock pin of shape part, makes the decurved tapered end in lock bolt front end be caught in the hole on lock tongue
It is interior, and lock tongue is lockked, at this time since the lower section of lock bolt is there are the boss for limit, lock tongue will be unable to continue to move, at this point,
Also there are the spaces of movement for the inside of sliding block, so that sliding block always can be with there are one when lock tongue insertion lock being made to push sliding block
Mobile space allows sliding block cannot be by bigger impact, and changing original latch in when lock tongue is inserted into is to need sliding block
Resist lock tongue.
4., by manual inside promoting button, button band pendulum lock pin moves in guide groove in unlock, reached in lock pin
Camber member connected to it can be guided to move during guide groove the top, understood because return spring resists the middle part of camber member
Sliding block is moved forward, increases return spring to the loading angle of lock bolt, is opened to make to lift and pop up on tapered end lock tongue completion
Lock.
