Abstract

The utility model discloses a pin tumbler lock, comprising a lock body and a lock core in the lock body, wherein, a pin tumbler with a plurality of V-shaped grooves and a pin tumbler offsetting spring are axially arranged on the lock core, and a locking side column groove is arranged on the lock core; a lock side column matched with the V-shaped grooves on the pin tumbler is arranged in the locking side column groove, and a stop block is arranged on the lock core; a locking side column offsetting elastic device is arranged between the stop block and the locking side column, and a groove corresponding to the locking side column groove on the lock core is arranged on the lock body; a communicated spiral groove is arranged on the lock body, and a protruding part matched with the spiral groove on the lock body is arranged on the lock core. The lock core makes axial movement relative to the lock body when rotating; a lock tongue can be axially controlled through the axial movement of the lock core in the lock, thus the utility model can be used on such occasions.

Description

A kind of ball lock head

Technical field

The utility model belongs to lockset, is specifically related to a kind of ball lock head.

Background technology

Existing ball lock head comprises the lock core in lock body and the lock body, and lock core has only rotating on the circumference relative to lock body under unlocking condition, will lock unlatching by the sword iron and the dead bolt interlock that are fixed on the lock core afterbody.This tapered end can not be used for along the lockset of lock core shaft's line traffic control dead bolt.

The utility model content

The purpose of this utility model is at above-mentioned situation, provide a kind of can be along the ball lock head of lock core shaft's line traffic control dead bolt.

Realize that the purpose of this utility model technical scheme is: ball lock head of the present utility model, comprise the lock core in lock body and the lock body, the lock core upper edge is axially arranged with some pellet shot from a slingshot and pellet shot from a slingshot back-moving springs that are provided with v-depression, lock core is provided with the locking side column groove, be provided with the locking side column that can match in the locking side column groove with v-depression on the pellet shot from a slingshot, on lock core, be provided with block, between block and locking side column, be provided with locking side column Flexible Reset device, the lock core afterbody is provided with locking bar, on the lock body with the corresponding groove that is provided with of locking side column groove on the lock core; On lock body, be provided with the helicla flute of perforation, be provided with the projecting part that matches with helicla flute on the lock body on the lock core.

Described locking side column Flexible Reset device also can correspondence be provided with the identical magnetic patch of polarity for spring is set between lock core block and locking side column between lock core block and locking side column.

The utility model is because lock core is provided with the projecting part that matches with helicla flute on the lock body, when inserting key unlocking, projecting part in the process of rotational lock core on the lock core will move by helicla flute on lock body, make lock core when lock body is made circular motion relatively, also do axially-movable, only need the backward rotation lock core during locking.The utility model tapered end is exactly to utilize this axially-movable of lock core to reach from the purpose of axial control dead bolt, therefore can be used for the lockset of this occasion.

The utility model is described in further detail below in conjunction with accompanying drawing.

The specific embodiment

As shown in Figure 1 to Figure 3, ball lock head of the present utility model, comprise the lock core 2 in lock body 1 and the lock body, lock core 2 upper edges are axially arranged with some pellet shot from a slingshot 5 and pellet shot from a slingshot back-moving springs 8 that are provided with v-depression 7, lock core 2 is provided with the locking side column groove, be provided with the locking side column 3 that can match in the locking side column groove with v-depression on the pellet shot from a slingshot 7, on lock core 2, be provided with block 9, between block 9 and locking side column 3, be provided with locking side column back-moving spring 10, lock core 2 afterbodys are provided with locking bar 13, on the lock body 1 with the corresponding groove 4 that is provided with of locking side column groove on the lock core 2; On lock body 1, be provided with the helicla flute 12 of perforation, be provided with the pin 11 that matches with helicla flute 12 on the lock body on the lock core 2.

After inserting key 6, locking side column 3 returns on the lock core 2 match with v-depression 7 on the pellet shot from a slingshot 5, lock core 2 can rotate relative to lock body 1, when with key 6 (referring to Fig. 4) during rotational lock core 2 in the direction of arrows, helicla flute 12 motions of pin 11 on the lock core 2 on lock body 1, make lock core 2 move right along axis simultaneously, the locking bar 13 that is located at control dead bolt on the lock core 2 returns in the lock body 1.When locking, with key backward rotation lock core, locking bar 13 is reached can be spacing with dead bolt (drawing) outside the lock body 1.

Also can on the notch of the locking side column groove on the lock core, magnetic block 14 be set, on locking side column,, utilize the repulsive force between magnetic block 14 and the magnetic patch 15 to make the locking side column return, as shown in Figure 5 with the magnetic block 14 corresponding identical magnetic patch of polarity 15 that are provided with.
