Description

Anti-violence opening spring lock core

Technical Field

The embodiment of the utility model provides a relate to key technical field, concretely relates to prevent violence and open pellet shot from a slingshot lock core.

Background

Cylinder locks, also known as ball locks, bead locks, bolt locks or pin tumbler locks, are one of the most common lock structures. Tumbler locks are commonly used in cylinder locks. The center of the cylinder type lock is a cylindrical hole, a cylindrical lock core is arranged in the cylindrical hole, and the lock core can rotate when the cylinder type lock is opened.

The middle of the lock core is a groove for placing a key, one end of the groove is opened for placing the key, and the tail end of the groove is provided with a lever. When the key is fully inserted, the lever receives a bolt to allow the lock core to rotate. The upper part of the groove is provided with a protruding part to prevent the lower marble from falling down and increase the difficulty of unlocking by a tool, five to six small holes are arranged above the lock core and form a straight line to place the lower marbles with different lengths, and the lower part of the lower marble is spherical to allow an inserted key to pass easily.

Above each lower marble is a corresponding driver pin (also known as an upper spring or upper ball). The flat head marble is pressed downwards by the spring. A simple lock is provided with only one flat head pin per lower pin. More complex locks, such as those that can be opened with multiple keys, have more than one flat tumbler on the lower tumbler. The lock has several vertical pits in the casing for holding flat head balls and springs.

When the pin tumbler lock is assembled, each pin tumbler is pressed into the lock core downwards by the spring. The place where the lock core is connected with the shell is called a cut point (shear point). After a proper key is inserted into the lock core, all the marbles are pushed upwards by the teeth of the key, the gaps between the marbles are just right at the intercept points, so that the lock core can be rotated, and the lock can be opened. After the key is pulled out, all the marbles fall off and are blocked above the interception point, and the lock cylinder cannot rotate.

The existing spring lock core has more and more safety because the mutual opening rate and the technical unlocking prevention problem are greatly improved, but the existing lock core still has the unsafe defect in terms of structure, for example, the poking wheel can be poked to open the lock core after the lock core is broken.

Disclosure of Invention

Therefore, the embodiment of the utility model provides an anti-riot power opens pellet shot from a slingshot lock core has solved the lock core and just can stir the thumb wheel and open the problem of lock core after being broken.

In order to achieve the above object, the embodiments of the present invention provide the following technical solutions:

the embodiment of the utility model provides an anti-violence opening spring lock core, which comprises a lock shell, an inner lock liner, an outer lock liner and a thumb wheel, wherein the inner lock liner, the outer lock liner and the thumb wheel are arranged in the lock shell;

the key technology is as follows: and a breaking groove which enables the lock shell to be easily broken is arranged on one side of the lock shell, which is close to the outer lock cylinder.

As a further improvement of the utility model, the inner lock cylinder is provided with a safety bullet hole, and a safety bullet, a safety spring and a steel ball are arranged in the safety bullet hole; a clutch is arranged between the thumb wheel and the inner lock container, and the clutch and the inner lock container can only axially move but can not relatively rotate; a clutch spring is arranged between the clutch and the inner lock liner, and a locking hole is formed in the thumb wheel;

the utility model discloses offer the rupture groove on the lock shell, when violence unblanked and destroy the lock core, the lock shell can be from the fracture of middle weakest rupture groove department, after outer lock courage takes place axial displacement, can be ejecting with clutch and thumb wheel through clutch spring, and insurance pellet shot from a slingshot inserts under the effect of insurance spring and dials in the wheel locking hole this moment, will dial the wheel lock through the inner lock courage and die, unable rotation.

Adopt the produced beneficial effect of above-mentioned technical scheme to lie in: the utility model discloses manufacturing process is simple, can effectually prevent that the violence from unblanking.
