[ Utility model ] content
The utility model aims at overcoming the defects of the prior art and providing a self-collision lock body component with simple structure and low production cost.
In order to solve the problem, the utility model adopts the following technical scheme:
the utility model provides a from bumping lock body subassembly, includes the casing, the casing in be equipped with the dead bolt that can stretch out the casing, suppress the dead bolt stretch out the outer dead bolt reset spring of casing, its characterized in that: the shell in articulated can pin the lock piece of square bolt after the square bolt withdraws in the casing, the casing in still be equipped with can be extruded and withdraw in the casing and drive the safety tongue of lock piece unblock, the casing in be equipped with the lock piece reset spring that can suppress the lock piece and move to pinning square bolt one side.
The self-latching lock body assembly is characterized in that: the safety tongue on the one end in the casing be equipped with the safety tongue guide block, the casing on be equipped with the guide way that extends along the safety tongue direction of contracting, the safety tongue guide block on be equipped with the guide post that stretches into in the guide way, the locking piece on be equipped with and dial the groove, the safety tongue guide block on still be equipped with one end and stretch into and dial the inslot and can slide and dial the post of dialling of locking piece unblock along dialling the groove.
The self-latching lock body assembly is characterized in that: the side edge of the square bolt is provided with a locking groove for the end part of the locking block to be clamped in.
As above a from bumping lock body subassembly, its characterized in that: the shell in articulated have when the square tongue stretch out the back one end can withstand the safety block of square tongue, can stir the safety block and rotate and make safety block one end change from the shifting block of square tongue, drive the shifting piece that rotates and stir the shifting block by the handle, the shell in still be equipped with the safety block reset spring that can suppress the safety block and reset.
The self-latching lock body assembly is characterized in that: and a top groove for pushing one end of the safety block into is arranged on the side edge of the square tongue.
The beneficial effects of the utility model are that: when the dead bolt retracts into the shell, the lock block props against the dead bolt, the dead bolt is not ejected, when the door is closed, the door leaf extrudes the safety bolt, the safety bolt retracts into the shell, the safety bolt drives the lock block, one end of the lock block is far away from the dead bolt, and the dead bolt is ejected out by the dead bolt reset spring, so that the dead bolt is automatically ejected, the structure is simple, and the production cost is low.

FIG. 2 is an exploded view of the present invention;
fig. 3 is a perspective view of the lock block of the present invention.
[ detailed description ] A
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
as shown in fig. 1 to fig. 3, a self-latching lock assembly includes a housing 1, a dead bolt 2 disposed in the housing 1 and capable of extending out of the housing 1, and a dead bolt return spring 3 for urging the dead bolt 2 to extend out of the housing 1, wherein the dead bolt return spring 3 is pressed when the dead bolt 2 retracts into the housing 1. The shell 1 is internally hinged with a locking block 4 which can lock the square bolt 2 after the square bolt 2 retracts into the shell 1, the end part of the locking block 4 props against the square bolt 2, so that the square bolt 2 can not move towards the extending direction, and the side edge of the square bolt 2 is provided with a locking groove 21 for the end part of the locking block 4 to be clamped in. The shell 1 is also internally provided with a safety tongue 5 which can be extruded to retract into the shell 1 to drive the locking block 4 to unlock, and two end surfaces of the safety tongue 5 are inclined, so that inclined surfaces of the door opening and closing locking block 4 can be extruded by a door frame, and the safety tongue 5 retracts into the shell 1. The shell 1 is internally provided with a lock block return spring 6 which can elastically press the lock block 4 to move towards one side of the locking square bolt 2, the lock block return spring 6 is pressed, and the lock block 4 is not easy to loosen.
One end of the safety tongue 5 in the shell 1 is provided with a safety tongue guide block 51, the safety tongue 5 is hinged on the safety tongue guide block 51, when the door frame extrudes the inclined surface of the safety tongue 5 to rotate, the safety tongue guide block 51 can retract under the acting force of the inclined surface, and the shell 1 is provided with a spring to elastically press the safety tongue 5 to reset. The housing 1 is provided with a guide groove 11 extending in the retracting direction of the safety catch 5. The safety tongue guide block 51 is provided with a guide post 52 extending into the guide groove 11, the lock block 4 is provided with a shifting groove 41, the safety tongue guide block 51 is also provided with a shifting post 53, one end of the shifting post extends into the shifting groove 41 and can slide along the shifting groove 41 to shift the unlocking of the lock block 4, the shifting groove 41 has a certain radian or an inclination angle, namely, the shifting groove 41 does not extend along the length direction of the guide groove 11, and thus when the shifting post 53 slides in the shifting groove 41, the lock block 4 can be shifted to rotate around a hinge shaft.
The safety block 7 which can prop against the dead bolt 2 when the dead bolt 2 is stretched out, the shifting block 8 which can shift the safety block 7 to rotate to enable one end of the safety block 7 to rotate away from the dead bolt 2 and the shifting piece 9 which is driven by the handle to rotate to shift the shifting block 8 are hinged in the shell 1, and the safety block reset spring 12 which can suppress the safety block 7 to reset is further arranged in the shell 1. The side edge of the square tongue 2 is provided with a top groove 22 for pushing one end of the safety block 7, the safety block 7 is provided with two branches, one branch is inserted into the top groove 22, the other branch is shifted by the shifting block 8, the square tongue 2 extends out and then is propped against the safety block 7, and therefore the square tongue 2 is not easy to damage and is pushed back into the shell 1.
