Anti-theft spring lock and key thereof

Abstract

Disclosed are an anti-theft spring lock and a key of the anti-theft spring lock. A key hole of the anti-theft spring lock is composed of a horizontal hole, an upright hole and a cylindrical hole which are mutually communicated. One end of the horizontal hole is arranged on a lock core end board, and the other end of the horizontal hole is arranged inside a lock core. A central line of the upright hole is coincided with a central line of the horizontal hole, one end of the upright hole is arranged at the front end of the lock core and a certain distance is arranged between the end of the upright hole and the lock core end board, the other end of the upright hole is arranged inside the lock core and is aligned to the horizontal hole, the lock core and the lock body are provided with spring lock holes with inclined angle of 180 degrees of each other and arranged at the coplanar positions with the upright hole, and marbles and springs are arranged inside the spring lock holes. One end of the cylindrical hole is aligned to the horizontal hole, the other end of the cylindrical hole is arranged at the tail end of the lock core, the sectional diameter of the cylindrical hole is equal to or larger than the radical length of the upright hole, and the anti-theft spring lock is strong in anti-theft capability. The key of the anti-theft spring lock comprises a key ring, a key handle and a key body fixedly connected at the tail end of the key handle, the key body is rectangular, grooves of 180 degrees with each other are arranged in the key body, the key cannot be copied easily, and mutual unlocking rate of the key is low.

Description

technical field [0001] The invention relates to a lock, in particular to an anti-theft tumbler lock, and also relates to a key for the anti-theft tumbler lock. Background technique [0002] The structure of the existing pin lock is: comprising a lock body, a cylindrical lock core rotatably installed in the lock body, the lock core is provided with a key hole in the axial direction, and the lock core and the lock body are radially provided with pins and springs, The pin part extends into the key hole. The key of the existing pin lock includes a key handle and a key body fixed to the end of the key handle. The key body is a strip plate, and teeth are milled on one edge of the strip plate. Slots are milled on both sides of the plate. Because the pins in the existing pin lock directly extend into the key hole, the distance and depth of the pins in the key hole can be detected, and thieves can easily insert them into the key hole by using tools such as steel (wire), hairpins, ma...

AI Technical Summary

Problems solved by technology

Existing tumbler locks are not dial-proof, existing keys are easy to be imitated, and the mutual opening rate of keys is high, which makes the existing tumbler locks have low insurance and anti-theft functions and poor safety and reliability.
