Description

Multi-directional anti-theft lock and multi-directional locking security door

【Technical field】

The invention relates to an anti-theft lock, in particular to an anti-theft lock which can be locked in multiple directions;

The invention also relates to an anti-theft door adopting the multi-directional anti-theft lock.

【technical background】

At present, a door lock is a device used to lock a door to prevent others from opening the door. This device may be mechanical or electric. As a security product, door locks must be safe and stable. Safety can be measured from two aspects: one is to resist vandalism, malicious or deliberate prying, drilling and other violent damage. The 2nd, prevent technology from opening, and the ability of preventing technology from opening of mechanical lock is very poor. According to market research and patent retrieval, it is found that the main structure of existing door locks is that the deadbolt is installed on one side of the lock, and the deadbolt extends out of the lock shell and can be locked when it extends to the corresponding lock groove. This structure, whether it is a mechanical lock It is still an electronic lock, and its safety performance is relatively poor, and it is easy to enter the gap between the lock groove and the door lock to enter violent damage such as prying and drilling, and the existing lockset has a complicated structure and high manufacturing cost. Most of the existing anti-theft guards have a side opening, and there are locks and a mechanism for executing the lock drive in the inside. Such locks have a low security level, so we developed a lock that opens to the bottom before improving the basis of opening to the side and applied for a patent. The announcement number is: CN203729702U, which discloses an electronically controlled door lock. It includes an electric control door lock body, which is characterized in that the electric control door lock body includes: a lock case with a cavity inside; the lock case includes a face cover and a bottom case; a through hole is opened on the bottom surface of the bottom case ; a lock cylinder mechanism, which is located in the cavity, and it includes a hook tongue, a stop block and a toggle piece for driving the stop block; a transmission mechanism, which includes a push-pull plate; the push-pull plate and the described push-pull plate The shifting piece is movably matched to drive the stop block, so as to realize the conversion of the hook tongue between the locking position and the unlocking position. The present invention also provides a door body, including a door leaf, a door frame and a lock bolt, the door leaf is equipped with an electric control door lock body, and the lock bolt is made of a long metal U-shaped; It has simple and firm structure, low manufacturing cost, convenient operation, wide application area, good reliability and safety, easy installation, simple structure, safe and reliable, and effectively resists vandalism and malicious Or deliberate prying, drilling and other violent damage.

Technological innovation is always carried out to meet the different requirements of customers. In order to achieve multi-directional locking, effectively improve the security level of locks and the ability to resist violent damage such as prying and drilling.
