Detailed Description

Embodiments of the present utility model will be further described with reference to fig. 1 to 2.

The utility model provides a multifunctional door lock, includes lock shell 1, is equipped with spring bolt subassembly 2 in the lock shell 1, still includes roller spring bolt subassembly 3, and it includes lock seat 30, drives the portion of stirring 31 that lock seat 30 left and right sides slided and is located the roller spring bolt piece 32 that can stretch out and draw back automatically of lock seat 30, lock shell 1 corresponds roller spring bolt piece 32 department and is equipped with fore shaft 10, stir portion 31 includes and dials wheel 310 and shifting block 311, the one end of lock seat 30 is equipped with lock chamber 300, is equipped with on the other end and dials chamber 301, the tip of shifting block 311 extends to and dials in the chamber 301, roller spring bolt subassembly 3 includes support 320 and ball 321, be equipped with slide 302 on the both sides wall of lock chamber 300, the both sides of support 320 are equipped with the movable slider 322 with slide 302 adaptation, be equipped with spring 323 between the bottom of support 320 and the diapire of lock chamber 300, when stirring wheel 310 clockwise rotation, shifting block 311 drives lock seat 30 towards the motion in the lock shell 1, spring bolt piece 32 is located lock shell 1, anticlockwise rotation 310, when shifting wheel 310 anticlockwise rotation, shifting block 321 extends towards outer side of lock chamber 10 by lock chamber 30. The outer wall of the lock seat 30 is provided with a limit sliding block 303, and the inner wall of the lock shell 1 is provided with a sliding groove 11 matched with the limit sliding block 303. The support 320 and the movable slider 322 are integrally arranged, a support groove 324 is formed in the support 320, a rotating shaft 325 is arranged in the ball 321 in a penetrating manner, and two ends of the rotating shaft 325 are matched with the side walls of the support groove 324.

Working principle: when the door leaf is not required to be completely locked and also required to be closed, the lock tongue assembly 2 can be contracted in the lock shell 1, and the roller lock tongue assembly 3 is used for temporarily locking the door leaf. By operating the toggle wheel 310 to rotate anticlockwise, the toggle wheel 310 drives the lock seat 30 to move towards the outer direction of the lock shell 1 when moving, and the movement of the lock seat 30 drives the balls 321 on the roller lock tongue block 32 to move from the lock notch 10 to the outer side of the lock shell 1. When the door leaf is closed, the ball 321 is abutted against the door frame, after the ball 321 is pressed, the ball is contracted towards the lock cavity 300 of the lock seat 30, the spring 323 is in a contracted state, and when the ball 321 moves, the movable sliding block 322 on the bracket 320 moves in a matched mode with the sliding way 302 in the lock seat 30, so that the stability of the movement of the ball 321 is improved. When the ball 321 moves into the lock box, the ball 321 is reset by the relaxation force of the spring 323 and is clamped in the lock box, so that the door leaf can be temporarily closed. When the door leaf is opened, the door leaf is forced to push, so that the ball 321 is contracted again, and the door leaf is opened quickly. The contact between the lock tongue assembly 2 and the door frame is reduced, and damage is avoided. Meanwhile, when the ball 321 locks the door leaf, rolling friction is carried out on the door frame, so that friction damage of the ball can be reduced, and the service life is prolonged.

When the door leaf needs to be completely locked, the poking wheel 310 is rotated clockwise to drive the lock seat 30 and the roller lock tongue block 32 to move towards the inside of the lock shell 1, and the lock tongue component 2 works independently to lock the door leaf, so that the operation is convenient.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
