Abstract

The utility model discloses a coded lock with a key, comprising a lock body and a shackle. A lock core and a lock head matching with each other are arranged in the lock body; the lock core is connected to the lower part of the lock body in a rotary manner; a lock hole used to limit the shackle is arranged on the top of the lock head; a push block extruding outward is arranged on the top of the lock core; the bottom of the lock head is a helical surface; the push block is butted against the helical surface; the lock core can be rotated to cause the push block to move along the helical surface to realize up-and-down movement of the lock head, thereby, the lock head is locked and disengaged from the shackle; and the external sleeve of the lock head has a return spring, the top end of the return spring is butted against the inner wall of the lock body, and the bottom end of the return spring is butted against the lock head. The utility model is capable to realize automatic separation of the shackle and the lock body; when the key is used for unlocking, the key rotates the lock core, the push block on the lock core is caused by the lock head to move on the helical surface under the driving action of the restoring force of the return spring; the lock head moves downward relatively to the lock core and disengages from the shackle, and thereby, unlocking is realized by free rotation of the shackle. The coded lock with a key has the advantages of simple structure, and convenient and rapid operation.

Description

A kind of band cryptographic key and lock

Technical field

The utility model relates to a kind of lockset, particularly relates to a kind of band cryptographic key and lock.

Background technology

The band cryptographic key and lock comprises lock body and lock bridge, is provided with tapered end in the lock body and is used to lock lock bridge, and it can adopt password and two kinds of open methods of traditional key.When adopting cipher wheel to unblank, take turns to proper password by rotational password after, the lock bridge of coded lock is popped up the disengaging tapered end, realizes unblanking purpose; When adopting traditional key unlocking, utilize key rotation lock core to remove fixing to tapered end, the top that promotes tapered end downwards with hand makes it break away from lock bridge again, realizes unblanking purpose.Owing to after adopting traditional key unlocking, still need manually could realize separating of lock bridge and lock body, so operate when adopting traditional key unlocking more loaded down with trivial details.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of band cryptographic key and lock, after can effectively solving existing band cryptographic key and lock and utilizing key unlocking, still needs manually the problem that lock bridge and lock body are broken away from.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of band cryptographic key and lock, comprise lock body and lock bridge, be provided with the lock core and the tapered end that cooperatively interact in the lock body, lock core is rotatably connected on the lock body bottom, the tapered end top is provided with the lockhole that is used for spacing lock bridge, it is characterized in that: the lock core top is provided with the pushing block to outer lug, the tapered end bottom is a helicoid, pushing block props up helicoid, rotational lock core makes the pushing block helicoidal motion realize the tapered end elevating movement, thereby makes the tapered end locking and break away from lock bridge.

Further, pushing block is a cylinder.

Further, pushing block is corresponding with the width of helicoid to the height of outer lug.

Further, the tapered end outside is with return spring, and the return spring top props up the lock body inwall, and the return spring bottom props up tapered end.

Further, helicoid is along tapered end spiral half cycle.

Further, the tapered end outer wall is provided with limited block, and limited block is located at return spring top, is provided with the chute corresponding with limited block in the lock body, and limited block slides along chute.

The utility model is owing to adopted technique scheme, can realize the disengaging of lock bridge and lock body automatically, when adopting traditional key unlocking, utilize key rotation lock core, tapered end makes the pushing block on the lock core move along the helicoid of tapered end under the impetus of return spring restoring force, thereby the relative lock core of tapered end moves downward and lock bridge breaks away from the lock bridge purpose of unblanking that reaches free to rotate, the utility model is simple in structure, and is convenient to operation.

The specific embodiment

As shown in Figures 1 to 4, be a kind of band cryptographic key and lock of the utility model, comprise lock body 1 and lock bridge 2, be provided with the lock core 3 and the tapered end 4 that cooperatively interact in the lock body 1, lock core 3 is rotatably connected on lock body 1 bottom, tapered end 4 tops are provided with the lockhole that is used for spacing lock bridge 2, tapered end 4 outsides are with return spring 5, return spring 5 tops prop up lock body 1 inwall, and return spring 5 bottoms prop up tapered end 4, and lock core 3 tops are provided with two pushing blocks 31 to outer lug, two pushing blocks 31 are cylinder, tapered end 4 bottoms are two helicoids 41, and each helicoid 41 is along tapered end 4 spiral half cycles, and pushing block 31 is corresponding with the width of helicoid 41 to the height of outer lug, two pushing blocks 31 prop up a helicoid 41 respectively, tapered end 4 outer walls are provided with limited block 42, and limited block 42 is located at return spring 5 tops, are provided with the chute corresponding with limited block 42 in the lock body 1, limited block 42 slides along chute, thereby tapered end 4 is spacing in the vertical direction elevating movement, prevent tapered end 4 owing to the frictional force effect rotates, influence the process of unblanking.

The utility model course of work is as follows:

When unblanking: utilize key rotation lock core 3, tapered end 4 is under the impetus of return spring 5 restoring forces, pushing block 31 on the lock core 3 is moved along the helicoid 41 of tapered end 4 bottoms, this moment, tapered end 4 relative lock cores 3 moved downward, realize the lockhole and lock bridge 2 disengagings at tapered end 4 tops, thereby lock bridge 2 can rotate freely and reaches the purpose of unblanking.

When carrying out locking: utilize the relative said process counter-rotation of key lock core 3, pushing block 31 on the lock core 3 moves along the helicoid 41 of tapered end 4 bottoms, because pushing block 31 is in sustained height all the time and only carries out circular motion, therefore pushing block 31 promotion tapered ends 4 relative lock cores 3 move upward, realize the lockhole at tapered end 4 tops and cooperating of lock bridge 2, thereby lock bridge 2 limited can't freely rotations reach the locking purpose, this moment, return spring 5 was compressed, and the restoring force when utilizing it to recover deformation in the process of unblanking plays a driving role to tapered end 4.
