Example Embodiment

[0020] Example 1: Such as figure 1 , figure 2 As shown, a clutch type anti-theft lock includes a lock shell 3 and a lock core installed in the lock shell. The lock core includes an inner lock core 10 with a key hole at the outer end, and an outer lock core 9 is sheathed outside the inner lock core. , There is a sliding assembly between the inner lock cylinder and the outer lock cylinder, that is, the inner lock cylinder can slide axially relative to the outer lock cylinder, and the inner lock cylinder can also rotate radially relative to the outer lock cylinder. The structure of the outer lock cylinder is as follows Figure 6 , Figure 7 As shown, the outer lock core is provided with an L-shaped chute 6. The chute can be a positive L-shaped chute or an inverted L-shaped chute. A sliding pin 7 is installed on the inner lock core. The sliding pin can be installed in the L-shaped chute. Slide in the sliding groove, the lock shell is provided with a pin hole, and a positioning pin 11...

Abstract

This is a separation-and-reunion pattern against theft lock. It contains: The lock core and lock cover two parts. In the lock core there are inner lock core and outer lock core, the outer lock core is covered on the outside of the inner lock core. On the inner side of the outer lock core install a separate-and-reunion pattern concave grooves, this grooves can plug in the plug late, on the plug plate install transporting rod, the out side end of transporting rod stretch out from clock cover, on the transporting rod install spring.

Description

Technical field [0001] The invention relates to a lock, in particular to a clutch type anti-theft lock. Background technique [0002] The lockset that uses now mostly adopts the traditional technology that the lock core fixes the drive rod and rotates to drive the dead bolt. The structure is simple and easy to use, but the anti-theft performance is relatively poor. With the improvement of people's safety awareness, the anti-theft performance of locks has been paid more and more attention, and its products are also constantly improving: on the lock head, some use cross locks, some use flat locks, and some use locks on the outer end of the lock head. Add metal covers, anti-drilling pieces, etc.; in terms of lock cylinders, its technical measures are mostly focused on improving keys, using multi-edged and multi-toothed keys and matching marbles, in order to reduce the mutual opening rate of keys. However, for those who have a certain experience in unlocking, this kind of lock ...
