Embodiment Construction

[0014] Examples such as Figures 1 to 4 As shown, a double anti-violence lock removal structure includes a lock case 1 , a lock case inner sleeve 2 arranged in the lock case 1 , and a lock cylinder 3 arranged in the lock case inner sleeve 2 . Described lock cylinder 3 is positioned at the front end of locking plate and is equipped with anti-breakage plate 9 that is resistant to breaking. The anti-smashing sheet 9 is made of a high-hardness metal material with a hardness greater than 55HRC, and the thickness of the anti-smashing sheet 9 is greater than 2mm to ensure sufficient strength. Therefore, it can resist damage to the lock plate by tools such as electric drills and screwdrivers, and has the first anti-theft function.

[0015] The end of the lock core 3 is provided with a first transmission block 4, the end of the lock core 3 is a cylindrical structure, and the middle of the first transmission block 4 is provided with a waist-shaped installation hole 403 matching with th...

Abstract

The invention discloses a dual violence-resistant unlocking structure. The dual violence-resistant unlocking structure comprises a lock case, a lock case inner sleeve and a lock cylinder, wherein a first transmission block is arranged at the tail end of the lock cylinder, a kidney-shaped mounting hole matched with the lock cylinder is formed in the middle of the first transmission block, and a fixing key clamped in the lock cylinder is arranged on one side of the kidney-shaped mounting hole; the first transmission block is further provided with a second transmission block, and the first transmission block is provided with a clamping slot adapted to the second transmission block; at least one draw pin locating slot is formed in the tail ends of the lock case an the lock case inner sleeve, the draw pin locating slot extends from the outer wall of the lock case to the lock case inner sleeve, and a draw pin is arranged in the draw pin locating slot; a torsional spring pressing the draw pininto the draw pin locating slot is also arranged at the tail end of the lock case; and the first transmission block is provided with an arc groove adapted to the draw pin, and the other end of the draw pin is arranged in the arc groove. The dual violence-resistant unlocking structure has a good anti-theft function and can be widely used in the anti-theft field of automobile locks.

Description

technical field [0001] The invention relates to the field of automobile lock cylinders, in particular to a double anti-violence lock removal structure. Background technique [0002] In the vehicle design of the car, the safety and anti-theft performance of the vehicle is placed in the first place. The traditional car lock anti-theft structure relies on the lock plate to pop out to the lock housing groove, so that the lock cylinder cannot rotate and start the anti-theft function; and due to the limited thickness of the lock plate , in the locked state, it blocks the edge of the lock shell groove, the force area is small, it is difficult to overcome the strong torsional force, it is easy to slip, the lock is forced to unlock, and it is easy to be unlocked by an illegal key, which seriously reduces the anti-theft performance of the lock. The coefficient is low. Therefore, need to develop a kind of lock cylinder structure with anti-theft function, to improve the safety of vehic...
