Bullet lock having bullet groups with different elastic forces

Abstract

The present invention relates to a billiard latch with two rows of billiard groups which are different each from other in spring force in which one row of billiard groups is thinner one and another row of billiard groups of thicker one which can prop said thiner row of billiard groups against its hole position, and said billiard latch is characterized by that when the billiard groups are arbitrarily slidden, said two rows of billiard groups are alternatively or simultaneously being in the state of preventing said billiard latch from being technically unlatched.

Description

technical field [0001] The invention relates to a pin lock, in particular to a pin locking structure of the pin lock. Background technique [0002] The existing upper and lower layers of mechanical pin locks locked by pins all have to slide in the opposite direction of the spring force in the unlocking direction of all the pin groups, so they cannot prevent technical opening. Specifically, a tool is used to twist the lock cylinder to force the pinholes to be misaligned and the lower pins are clamped at the dislocation of the pinholes, and then all the lower pins are pushed into the pinholes on the lock core one by one by turning the upper pins. However, the lower pin that is pushed into the pin hole on the lock core body will not enter the pin hole on the lock cylinder due to being blocked by the dislocation of the pin hole, and the upper pin is also blocked by the dislocation of the pin hole. Will not be pushed into the pin hole on the lock cylinder body. Therefore, the t...

Problems solved by technology

[0005] The invention solves the problem that the traditional mechanical pin locks locked by the upper and lower layers of pins cannot prevent technical opening; it solves the problem of the existing traditional mechanical pin locks locked by the upper and lower pins and the single-layer pins in the lock cylinder The anti-theft tumbler lock with side column locking structure has the problem that the sliding direction of all the tumbler groups must slide in the opposite direction to the direction of the spring force; it solves the problem of the anti-theft tumbler lock with single-layer pin side column locking structure in the lock cylinder and Magnetic tumbler locks, the problem that the setting amount of the pin group is limited; solve the problem that the existing magnetic pin locks cannot control the sliding level of the magnetic pins
