Problems solved by technology

The anti-theft performance of such a structure is very poor. You only need to find a way to make the lock cylinder rotate or bypass the lock cylinder and directly turn the cam to open the door, so the anti-theft performance is not good.

Embodiment 1

[0025] The present invention is achieved through the following technical solutions:

[0026] Lock cylinder structure reference figure 1 and figure 2 , comprising a front lock cylinder 1 and a rotatable pin 2. The front lock core 1 is divided into 8 drilled holes in two rows up and down and 8 rotatable angle pins 2 installed in the drilled holes. The inner diameter of the drilled holes is mm, the outer diameter of pin 2 is mm, the distance between any marble in the upper row and the virtual center of the adjacent upper row of marbles is 6mm, and the distance H1 between any marble in the upper row and the virtual center of the adjacent lower row of marbles is 4mm. The distance H2 between the virtual center of an upper row of pins parallel to the axis of lock cylinder 1 and the line passing through the virtual center of the lower row of pins adjacent to the pin and parallel to the axis of lock cylinder 1 is 2.5mm .

Embodiment 2

[0028] Structural reference of the key matched with the lock cylinder structure image 3 , including a spoon body 11 and a pit 12. What is set on the spoon body 11 is divided into 8 pits 12 corresponding to the upper end shape of the marble 2 of the rotatable angle in two rows up and down, and the inner diameter of the pit 12 is mm, the distance between any one pit in the upper row and the virtual center of the adjacent upper row of pits is 6mm, the distance between any one pit in the upper row and the virtual center of the adjacent lower row of pits is 4mm, Between a straight line passing through the virtual center of any upper row of pits and parallel to the longitudinal centerline of the spoon body and a straight line passing through the virtual center of the lower row of pits adjacent to the pit and parallel to the longitudinal centerline of the spoon body The distance is 2.5mm.

Embodiment 3

[0031] refer to Figure 4-Figure 6 , including a front lock cylinder 1, a locking block spring 5, a rotatable angle pin 2, a locking block 4, a lock cylinder sleeve 5, and a slot 6.

[0032] Others are the same as embodiment 1, except that there is a lock core cover 3 with a circular through hole, a front lock core 1 installed in the lock core cover 3 circular through holes, 8 marbles 2 installed on the front lock core 1, The inner wall of the circular through hole of the lock core sleeve 3 is along the X axis, with the axis of the circular through hole as the origin, and a slot 31 is respectively arranged at 0° and 180° on the Y-Z plane, along the X axis, before The axis of the lock core 1 is the origin, and two lock blocks 4 and lock block springs 5 ​​are set at 0° on the Y-Z plane to pass through the front lock core 1 and cooperate with two marbles 2 respectively; The locking block 4 and the locking block spring 5 which are matched with the front lock cylinder 1 and the tw...

Abstract

The invention discloses a multiplex anti-theft lock. The multiplex anti-theft lock comprises a lock cylinder sleeve, a front lock cylinder and a rear lock cylinder, wherein the front lock cylinder and the rear lock cylinder are installed in a round through hole of the lock cylinder sleeve, N drilling holes in an upper row and a lower row, N elastic bodies and elastic body springs are arranged on the front lock cylinder the N elastic bodies and the elastic body springs are installed in the drilling holes, and N>= 3. The multiplex anti-theft lock is characterized in that the circumcircle tangent line, parallel with and adjacent to the central axis of the front lock cylinder, of any elastic body in the upper row, is intersected with the circumcircle of any elastic body in the lower row, and the circumcircle tangent line, parallel with and adjacent to the central axis of the front lock cylinder, of any elastic body in the lower row, is intersected with the circumcircle of any elastic body in the upper row. The multiplex anti-theft lock is safer in structure, simple in mechanism and low in cost.

Description

technical field [0001] The present invention relates to locks, in particular to anti-theft locksets. Background technique [0002] At present, the layout and arrangement structure design of the pins of the lock cylinder part of the anti-theft lock is generally a linear arrangement, and the anti-theft of the lock is realized by the different positions of the pins in the lock core. This structure only needs to use tools to transfer all the positions of the marbles into the lock cylinder, so that the lock cylinder can be rotated to unlock, and the anti-theft performance is average. Although the Chinese invention patent "A Double-row Pin Idling Lock Cylinder" with the publication number 102337800A discloses a double-row pin structure, the double-row pin pins in this structure are symmetrically distributed and there are still gaps between the lines connecting the outer edges of the double-row pin pins. Malicious tools can still reach the clutch rotor inside the lock cylinder thr...
