Description

a pin lock

technical field

The utility model belongs to locks, in particular to a tumbler lock head.

Background technique

The existing pin lock head includes the lock body and the lock cylinder in the lock body. In the unlocked state, the lock cylinder only rotates on the circumference relative to the lock body, and the lock is opened by the lock ruler fixed at the tail of the lock cylinder and the dead bolt. Such lock cylinders cannot be used for locks that control the deadbolt along the axis of the cylinder.

Utility model content

The purpose of this utility model is to provide a pin lock head that can control the lock tongue along the axis of the lock cylinder in view of the above situation.

The technical solution to achieve the purpose of this utility model is: the pin lock head of the present utility model includes a lock body and a lock core in the lock body, and the lock core is axially provided with several pins with V-shaped grooves and pin return springs, The lock cylinder is provided with a locking side column groove, and a locking side column that can be matched with the V-shaped groove on the pin is arranged in the locking side column groove, and a stopper is arranged on the lock cylinder, between the stopper and the locking side column There is an elastic device for resetting the locking side post, a lock rod is provided at the end of the lock cylinder, and a groove is provided on the lock body corresponding to the locking side post groove on the lock cylinder; a through spiral groove is provided on the lock body, and a There are protruding parts that match the helical grooves on the lock body.

The elastic device for restoring the locking side post is to arrange a spring between the lock cylinder stopper and the locking side post, and a magnetic block with the same polarity can also be correspondingly arranged between the lock cylinder stopper and the locking side post.

In the utility model, since the lock core is provided with a protruding part that matches the spiral groove on the lock body, when the key is inserted to unlock the lock, the protruding part on the lock core will move along the spiral groove on the lock body during the process of rotating the lock core. The lock core is made to move axially while doing circular motion relative to the lock body, and only needs to reversely rotate the lock core during locking. The lock head of the utility model utilizes the axial movement of the lock cylinder to achieve the purpose of controlling the dead bolt in the axial direction, so it can be used for locksets in such occasions.

Below in conjunction with accompanying drawing, the utility model is further described.

Detailed ways

As shown in Figures 1 to 3, the pin lock head of the present utility model includes a lock body 1 and a lock core 2 in the lock body. The lock core 2 is axially provided with a number of pins 5 with V-shaped grooves 7 and Pin reset spring 8, lock core 2 is provided with locking side post groove, and locking side post groove is provided with locking side post 3 that can cooperate with V-shaped groove 7 on the pin, and lock core 2 is provided with stopper 9 , between the block 9 and the locking side post 3, a locking side post return spring 10 is provided, a lock lever 13 is provided at the tail of the lock cylinder 2, and a groove 4 is provided on the lock body 1 corresponding to the locking side post groove on the lock cylinder 2 ; The lock body 1 is provided with a through spiral groove 12, and the lock cylinder 2 is provided with a pin 11 that matches the spiral groove 12 on the lock body.

After inserting the key 6, the locking side column 3 on the lock cylinder 2 returns to match the V-shaped groove 7 on the marble 5, and the lock cylinder 2 can rotate relative to the lock body 1. When the key 6 is used to rotate the lock cylinder 2 in the direction of the arrow (see Fig. 4), the pin 11 on the lock core 2 moves along the spiral groove 12 on the lock body 1, so that the lock core 2 moves to the right along the axis at the same time, and the lock rod 13 which is arranged on the lock core 2 to control the dead bolt returns into the lock body 1. When locking, reversely rotate the lock cylinder with a key so that the lock bar 13 is stretched out of the lock body 1 and the dead bolt (not pictured) can be limited.

Magnetic block 14 can also be set on the notch of the locking side post groove on the lock core, and magnetic block 15 corresponding to magnetic block 14 is provided with the same polarity on the locking side post, utilizes between magnetic block 14 and magnetic block 15 The repulsive force between them makes the locking side post return, as shown in Figure 5.
