Description

Anti-prying lock and linkage control structure thereof Technical Field The invention belongs to the technical field of anti-theft locks, and particularly relates to a linkage control structure of an anti-prying lock and the anti-prying lock. Background The door lock is widely applied to house entrance doors, apartment doors, office entrances and exits, and closed spaces such as lockers, file cabinets and the like, and is one of the most common basic components in the security and protection five-metal field. The door body or the cabinet door is controlled to be opened or closed mainly through the cooperation among the key, the lock core and the lock tongue, so that daily protection is formed for property, personnel and privacy in the space. In long-term application, the door lock not only bears the physical blocking function, but also directly relates to the convenience in use, the service life and the scene adaptability. In the actual use process, the door lock is usually required to face the working condition influences of frequent opening and closing, long-term abrasion, external force impact, complex human contact and the like. Particularly in houses, renting places and partial public areas, the door lock is required to have better abnormal opening resistance besides bearing normal opening and closing functions. If the lockset is still easy to generate internal transmission instability, locking failure or abnormal action of the lock tongue under the conditions of stress, torsion or prying, the protection reliability is reduced, and the basic requirement of a user on the safety is influenced. For the above-mentioned situation, the existing door lock usually adopts the key to insert the lock core and then directly drive the inner thumb wheel of lock core or corresponding transmission part, the transmission part drives the lock tongue to move, in order to finish unlocking and locking operation. The scheme has relatively visual structure, mature manufacturing and assembling modes, and can meet the basic use requirements in general household and conventional security scenes, so that the scheme is widely applied to the existing market. However, under some use occasions with higher requirements on anti-prying and anti-theft performance, the existing door lock scheme still has certain limitations. Firstly, under the action of abnormal external force, the stability and locking reliability of the internal transmission relation are easily affected, secondly, when the lock faces abnormal contact, continuous prying or forced force application, the whole anti-damage capability of the lock still has room for improvement. As a result, the door lock is still deficient in terms of safety continuity, abnormal opening blocking capability, and practical use. Disclosure of Invention The invention aims to provide a linkage control structure of a prying-resistant lock and the prying-resistant lock, which can improve the locking reliability and prying-resistant and theft-resistant performances of a door lock under an abnormal prying working condition. In order to achieve the above purpose, the present invention adopts the following technical scheme: The invention provides a linkage control structure of a prying-resistant lock, which comprises a first lock cylinder (101), a second lock cylinder (102) and a prying-resistant mechanism (3) arranged in the first lock cylinder (101), wherein the prying-resistant mechanism (3) comprises a lock plate (31), a locking component (36), an unlocking component (37) and a supporting component (38), the lock plate (31) is slidably connected inside the first lock cylinder (101), the lock plate (31) can move along the axial direction of the first lock cylinder (101) and is in plug-in fit with the second lock cylinder (102), the locking component (36) is arranged in the first lock cylinder (101) and is used for locking the lock plate (31), the unlocking component (37) is matched with the locking component (36) to release the locking of the lock plate (31), and the supporting component (38) is matched with the unlocking component (37) to drive the unlocking component (37) to act; Under the action of an external driving piece, the supporting component (38) drives the unlocking component (37) to act, so that the locking component (36) releases the locking of the lock plate (31), and the lock plate (31) moves to the inside of the second lock cylinder (102) along the axial direction of the first lock cylinder (101), so that a transmission connection relation is established between the first lock cylinder (101) and the second lock cylinder (102), and the movement of the first lock cylinder (101) can be transmitted to the second lock cylinder (102) through the lock plate (31); When the interlocking control structure is unlocked by using a matched external driving piece, the locking assembly keeps the locking state of the locking plate (31), so that the locking plate (31) cannot move into the second lock
