Abstract

The invention discloses a high strength antitheft dial plate lock. The high strength antitheft dial plate lock comprises a code lock, a key lock and a rotary knob, wherein the key lock comprises a lock core and a locking dog plate which are arranged on the rotary knob and used for locking or unlocking a rotation state of the rotary knob, the code lock comprises a code wheel and a tail end code wheel, a groove is formed between each two adjacent figures of the code wheel, a deadlock mechanism and an induction system which are used for limiting rotation of the code wheel are further arranged in a housing, the induction system comprises a second slide block, a sensor, an electrified magnet and a permanent magnet, the sensor and the electrified magnet are interconnected, the code wheel can enable the second slide block to trigger the sensor through rotation, and when the code wheel rotates according to a wrong sequence, the electrified magnet is powered on and locks the deadlock mechanism dead. The high strength antitheft dial plate lock is simple in structure, and achieves the purpose that an external user cannot unlock the high strength antitheft dial plate lock even under the situation that the external user knows a code through a code wheel rotation sequence preset by a user of the high strength antitheft dial plate lock.

Description

technical field [0001] The invention relates to the technical field of mechanical combination locks, in particular to a high-strength anti-theft dial lock. Background technique [0002] The mechanical combination lock is a reliable all-mechanical combination lock with a large key volume without electronic devices; the mechanical combination lock usually used is a dial-type mechanical combination lock; it has the characteristics of not easy to crack, high security, small size and weight Lightweight, suitable for use in very important places such as vault doors, gun cabinets, safes, etc., but the digital combination of button-type mechanical combination locks currently on the market is single, easy to crack, and easy to be cracked by other people's locks, safe Sex is poor. Contents of the invention [0003] The main purpose of the present invention is to provide a high-strength anti-theft dial lock to solve the above-mentioned deficiencies in the prior art, which can effect...
