Abstract
The utility model discloses a night lock, and is characterized in that: the retraction distance of a marble is controlled by adding a rigid post body in a spring inside the lock body, thereby the purpose of which different locks are opened with different keys can be reached. For the manufacturers, the production costs are not increased, but the security is multiplied.
Description
Technical field: the utility model relates to lock, relates in particular to cylinder lock.
Background technology: cylinder lock is to use maximum a kind of locks in people's daily life, in the lock body of cylinder lock, vertical with the lock core direction, transverse row is shown several spring roads, in each spring road, top spring and two pellets shot from a slingshot is arranged all, under the effect of top spring, some extend into the pellet shot from a slingshot of close lock core in the aperture corresponding on the lock core, so just can control lock core and rotate, and pellet shot from a slingshot plays the effect of " pin ".When needs are opened lock, key is inserted in the lock core, the pellet shot from a slingshot that utilizes key bit on the key will stretch in the lock core pushes away lock core, promptly removes " pin ", and lock core is promptly rotatable, the corresponding contraction of the dead bolt that links to each other with lock core, lock then is opened.This lock technology, structure are all very simple, and cost is also low, but safety is also low.The somebody utilizes iron plate, bamboo let can open lock.Bring property and life danger to people easily.
Technical purpose: the purpose of this utility model provides the cylinder lock after a kind of the improvement, by adding a rigidity cylinder in the top spring in lock body, controls pellet shot from a slingshot retraction distance, really reaches the purpose of opening different locks with different keys.
Technical scheme: the purpose of this utility model is achieved in that
In all top springs in lock body, select at least two top springs at random, respectively add a rigidity cylinder therein.
The length of rigidity cylinder must be: the length that the length of rigidity cylinder adds two pellets shot from a slingshot just in time and in the lock core keyhole equate near side to the distance between the lock body sidewall of top spring.
Described in detail below in conjunction with accompanying drawing.
Fig. 1 is a cross-sectional view of the present utility model.
As shown in the figure: under the effect of top spring 2, some extend in the aperture corresponding on the lock core 3 near the pellet shot from a slingshot 1 of lock core 3, and control lock core 3 rotates;
In at least two top springs 2 selecting at random, respectively add a rigidity cylinder 4, the length that the length of rigidity cylinder 4 adds two pellets shot from a slingshot 1 just in time and in the lock core keyhole 5 equate near side to the distance between lock body 6 sidewalls of top springs.
When the people utilizes other instrument to unblank,, controlled the retraction distance of pellet shot from a slingshot 1 because rigidity cylinder 4 is arranged in the top spring 2.Lock is difficult for being opened.
Beneficial effect: adopt above-mentioned measure, can effectively control pellet retraction distance, really reach To the purpose of opening different locks with different keys. And concerning manufacturer, increase hardly cost, But security performance is multiplied.
Claims (1)
1, a kind of cylinder lock is characterized in that: in all the top springs in lock body, respectively add a rigidity cylinder at least in two top springs; The length of rigidity cylinder add two pellets shot from a slingshot length should and lock core in keyhole equate near side to the distance between the lock body sidewall of top spring.
