This containment vessel covers lock body and lock box fully, prevents the handgrip clothes is tangled on the lock body, and when bumping, the collision area of human body and this containment vessel is big, reduces pain.When opening the door, pull containment vessel, it is rotated around pin joint, in rotating process, the effect that driving-belt pulls, it is mobile backward to drive dead bolt, and after dead bolt broke away from lock box, door was opened.After door was opened fully, the elastic force of spring promoted dead bolt and moves forward, and dead bolt drives driving-belt again, thereby the pulling containment vessel rotates around its pin joint, and containment vessel covers lock body.The opening and closing process operation of this door lock is convenient, and anticollision is effective.
In above-mentioned anticollision door lock, be provided with positioning step in the described lock body, an end of above-mentioned spring is resisted against on this positioning step, and its other end is resisted against on the dead bolt.
In above-mentioned anticollision door lock, the rear end of described dead bolt is provided with a joint pin that is located between the above-mentioned positioning step, and above-mentioned spring housing is located on this joint pin, and the end of above-mentioned driving-belt is fixed on this joint pin.
This joint pin plays balanced action to dead bolt between positioning step.
In above-mentioned anticollision door lock, also be provided with a roller bearing that is positioned at described joint pin rear end in the described lock body, above-mentioned driving-belt is walked around this roller bearing, and it is in the same plane with the axis of described joint pin that described driving-belt is walked around the part of this roller bearing.
This roller bearing makes the driving-belt commutation, and makes the part that acts directly on the dead bolt in the same plane with the axis of joint pin, has effectively guaranteed retreating of dead bolt.
In above-mentioned anticollision door lock, the lateral surface of described containment vessel is provided with the cushion coat of being made by elastomeric material.
This cushion coat can play cushioning effect to human body, with a large amount of absorbing forces of impact, human body is played a good protection.
Compared with prior art; the reasonable in design of this anticollision door lock; easy to operate; anticollision is effective; the outside at containment vessel is provided with cushion coat, effectively absorbs the power that collision produces, and human body is played a good protection; under the effect of dead bolt at spring, can cover lock body and lock box, automaticity height automatically.
