Square internal multifunctional mechanical lock

Abstract

The invention relates to a square internal multifunctional mechanical lock with a unique lock pin transmission structure. The lock comprises a lock shell, a lock cylinder and a lock pin. The lock cylinder is arranged in the lock shell. The square internal multifunctional mechanical lock is characterized in that the lock cylinder is arranged in an inner sleeve in a matched manner, and the inner sleeve is fixedly installed in the lock shell; the lock cylinder comprises a lock cylinder body, two clamping blocks, two rows of cylinder sets and corresponding two rows of spring sets; the lock cylinder body is provided with a key inserting groove along the axis of the lock cylinder body; clamping block grooves are formed in the two opposite side faces of the lock cylinder body, and two rows of cylinder grooves are formed in the other two opposite side faces of the lock cylinder body; the cylinder grooves, the clamping block grooves and the key inserting groove communicate with one another; each cylinder of each cylinder set presses one spring into one corresponding cylinder groove; the face, close to the corresponding clamping block groove, of each cylinder of each cylinder set is provided with a groove; and the face, facing the key inserting groove, of each cylinder of the cylinder set is provided with a protruding block. By means of the square internal multifunctional mechanical lock with the unique lock pin transmission structure, due to the fact that the lock cylinder is rotated, the lock pin is driven through a stirring piece, the lock pin locks a door or a box in a pining manner or an electronic lock pin in the door or the box is used, and the lock pin is used for achieving locking, so that safety 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. The production cost is high and failures are prone to occur. These problems are all caused by the structure of the lock cylinder, so the research and development of the lock cylinder is particularly important.

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
