Abstract

A spring lock has the cylinders for main body and the cylinders for core, which are linked via T-shape flange and T-shapeslot. There is slot ring on the periphery of lock core. When an external impact force is applied to the lock, it can prevent the cylinders of main body from being separated from those for core, so having higher security.

Description

A kind of cylinder lock

The present invention relates to a kind of lock, particularly a kind of cylinder lock.

The structure of existing cylinder lock is roughly the same, be in the pellet shot from a slingshot hole of lock body lock core cylinder-shaped marble to be housed all, the tartar that corresponding different length pellet shot from a slingshot is arranged on the key, the mode of unblanking is also roughly the same, promptly the height difference by key tooth flower moves up and down corresponding pellet shot from a slingshot, make the height of each lock core marble all be in the interface place of lock body and lock core, rotational lock core reaches the purpose of unblanking.Between the lock spring of existing cylinder lock and the lock core marble when being subjected to along the axial impulse force of pellet shot from a slingshot, the space appears easily.When lock core is applied a torsion, again it is applied along the pellet shot from a slingshot axis under the condition of the impulse force of lock body direction, between lock spring and the lock core marble just segregation phenomenon can appear, this moment, cylinder lock was very easily opened by foreign matter, in addition, again lock core is applied commutation torsion when stirring pellet shot from a slingshot with master key, radially reaching axial relative displacement meeting in this case between lock spring and the lock core marble takes place simultaneously or alternately, and above-mentioned displacement can perceive, can survey, existing cylinder lock ubiquity the shortcoming of measurability, so safety is relatively poor.

The present invention is directed to that existing the problems referred to above provide a kind of cylinder lock in the prior art, its main purpose is: this cylinder lock is under lock-out state, lock spring and lock core marble are connected as a single entity, thereby prevent because of being subjected to the external force effect, lock spring with play when occurring separating between the core pellet shot from a slingshot, cylinder lock is opened by foreign matter.

Another object of the present invention is: prevent that when stirring pellet shot from a slingshot with master key the phenomenon that reaches radial displacement to axial between lock spring and the lock core marble occurs simultaneously or alternately, gets rid of the measurability of cylinder lock, improves its safety.

Above-mentioned purpose of the present invention is achieved in that provides a kind of cylinder lock, and described cylinder lock comprises lock body, lock core, marble spring, lock marble hole, lock core marble hole, lock spring, lock core marble and key, it is characterized in that; Lock core marble radially has a T-slot at an end adjacent with lock spring, lock spring is the end that lock core marble is adjacent, have one with the T shape flange of described T-slot loose fit, lock spring and lock core marble are under the concentric at lock marble hole and lock core marble hole and are connected as a single entity, and can in lock marble hole and lock core marble hole, slide, described lock core marble has a protuberance that extends radially outward from its outer rim, the lock core marble hole inwall has a groove that is parallel to the lock core marble centerline hole, described protuberance is maintained in the described groove, described protuberance and described groove are slidingly matched, corresponding each lock core marble hole has along the annular groove in week on the lock core outer rim, and this annular groove and described lock spring T shape flange are slidingly matched.

In second preferred embodiment, the lock spring of this cylinder lock and lock core marble have respectively that in the hole and lock core marble the hole in the identical lock spring of diameter, hole in the described lock spring) and in the lock core marble in the hole, lock spring core and lock core marble core are housed respectively, the lock spring core is towards lock body one end, there is a pellet shot from a slingshot core spring on the top, the other end of this pellet shot from a slingshot core spring acts on the lock body, in described lock spring core and lock core marble core and the described lock spring in hole and the lock core marble hole be slidingly matched, described have the tartar that corresponds respectively to lock core marble and lock core marble core on the key.

A kind of cylinder lock of the present invention is under lock-out state, owing to be connected as a single entity with the cassette connected mode between lock spring and the lock core marble, so, as lock spring can not separate with lock core marble when running into external shock power, can only link, thereby can prevent from effectively to adopt lock core is applied torsion, pellet shot from a slingshot is applied the means unlocking spring lock of impact force; Owing in lock spring and the lock core marble lock spring core and lock core marble core have been installed, under lock-out state, axially reach between lock spring and the lock core marble and radially relative displacement can not take place, thereby eliminated the measurability of cylinder lock, improved the safety of cylinder lock.
