Square built-in multifunctional mechanical lock

Abstract

The invention relates to a square built-in multifunctional mechanical lock with a unique lock pin transmission structure. The lock includes a lock case, a lock cylinder and a lock pin. In the sleeve, the inner sleeve is fixedly installed in the lock shell; the lock cylinder includes a lock cylinder main body, two blocks, two rows of marble groups and corresponding two rows of spring groups, the lock cylinder main body has a key slot along the axis, and the lock cylinder Block grooves are arranged on the opposite sides of the main body, and two rows of pin grooves are arranged on the other opposite sides of the main body of the lock cylinder. Pressed in a pin groove, each pin of the pin group is provided with a groove facing the side adjacent to the block groove, and each pin of the pin group is provided with a protrusion facing the side of the key slot. This kind of lock rotates the lock cylinder and uses the plectrum to drive the lock pin, so that the lock pin pins the door or the box, or the electronic lock pin in the door box, and the lock pin is used to realize locking, so the security is higher.

Description

technical field [0001] The invention relates to a lock, in particular to a square built-in multifunctional mechanical lock applied to a safe or a door. Background technique [0002] At present, there are many types of locks on the market, and the structure of the lock cylinder is different. Therefore, both in terms of quality and anti-theft performance, they all have their own advantages, but overall there are still many problems, such as difficulty in unlocking, poor anti-theft performance, and too complicated structure.

Problems solved by technology

[0002] At present, there are many kinds of locks on the market, and the structure of the lock cylinder is different. Therefore, both in terms of quality and anti-theft performance, they all have their own merits. However, there are still many problems in general, such as difficulty in unlocking, poor anti-theft performance, and too complicated structure. The production cost is high and failures are prone to occur. These problems are caused by the structure of the lock cylinder, so the research and development of the lock cylinder is particularly important.

[0003] In ordinary locks, after the key is matched with the lock cylinder, the lock cylinder drives the lock pin to move to realize unlocking. There are many ways for the lock cylinder to drive the lock pin to expand and contract, and the corresponding transmission structure is also very different, but the common transmission mode is no other. In the case of mechanism assistance, the unlocking feel will be very poor, that is, there is no perceivable transition feeling in the process from locking to unlocking. From another perspective, if there is no transition feeling, it is impossible to know where the lock is from the feel. when to unlock, when to lock
