Embodiment Construction
[0024] The present invention is an angle rotation positioning lock cylinder, such as figure 1 , 2 , 3, 4, including a housing and a lock core shaft 1 arranged in the housing, the lock core shaft 1 is set from the outer end of the housing to the inner end. The lock core shaft 1 is connected with a push spring 2 that can push the lock core shaft 1 to move in and out or up and down. The side surface of the lock core shaft 1 is provided with a slide groove 3 along its axial direction, and a plurality of card slots are provided along its radial direction. The groove 4, the sliding groove 3 and the locking groove 4 form two combs placed opposite to each other on the side of the lock core shaft 1. At different height positions of each card slot 4, there is an angle locking member 5 that can slide along the card slot 4 and is used to control the movement of the lock core shaft 1. The angle locking member 5 includes passive rods 5-1 and Active rod 5-2, passive rod 5-1 and the angle o...

The invention discloses an angle-rotation positioning cylinder comprising a shell and a cylinder shaft arranged in the shell. The cylinder shaft is connected with a pushing spring capable of pushing the cylinder shaft to move inwards and outwards or upwards and downwards. A sliding groove is formed on the side of the cylinder shaft axially, and a plurality of clamping grooves are formed on the side of the cylinder shaft radially. Angle stopping members which are capable of sliding along the clamping groove and which are used for controlling the movement of the cylinder shaft are arranged on each clamping groove. The angle stopping members comprise passive rods and active rods which are provided with crossed angles. The free ends of the passive rods are inserted in the clamping grooves. The sides of the free ends of the active rods are connected with the shell through reset springs, the other sides of the free ends of the active rods are provided with pushing blocks capable of pushing the free ends of the active rods to move left and right so as to realize the passive rods to move along the clamping grooves. The other ends of the pushing blocks are communicated with a keyhole. According to the angle-rotation positioning cylinder, the angle stopping members are utilized to control the movement of the cylinder shaft, the cylinder is not driven to rotate by a key, the cylinder is prevented from damaging due to violent unlocking, and difficulty of violent unlocking is further increased.
Description
technical field [0001] The invention relates to a mechanical lock, in particular to an angle rotation positioning lock core and a lock using the lock core. Background technique [0002] The existing mechanical locks mainly include mechanical pin locks and mechanical shrapnel locks. The principle of mechanical pin locks is to use a plurality of cylindrical parts (called lock springs, pins or beads) of different heights to lock the lock cylinder. When the correct key is put in, each lock spring is pushed to the same height, and the space between the upper and lower pins is in a straight line, which is aligned with the lock cylinder. When the space between the pins is aligned with the rotation line, the lock cylinder can be rotated , the lock can also be opened; the mechanical shrapnel lock locks the lock cylinder through the shrapnel on the lock cylinder. Both of these two locks have a low mutual opening rate and certain anti-theft capabilities, but since these two locks are ...
