Description

A cathode lock with preload release function

technical field

The utility model relates to a lock, in particular to a cathode lock with the function of pre-press release.

Background technique

Commonly found in public buildings or private areas (home environment), most of them are equipped with traditional mechanical access control equipment. However, when encountering midnight invasions, their ability to prevent them is often subjected to a considerable test, so more intelligent access control equipment has been derived. Access control equipment to properly maintain the safety of their lives and property.

Therefore, in addition to traditional mechanical access control equipment, common door locks further include electronic and electric control locks, which are classified into electric dropbolt or cathode locks and other types of locks. This kind of electronic and electronically controlled locks only use electrical switches to switch, and cooperate with the operation mode of electromagnetic magnet (coil) to open and close the lock, so as to achieve the function of access control. Therefore, Chinese Patent No. M349426 discloses an "electromagnetic lock structure", which is shown in Figure 1 in the case of No. M349426, which includes a fixed plate body, an accommodating body, and a hook portion. The hook portion has a pivoting rod. Moreover, an electromagnet and a resisting part are provided, and the electromagnet is connected with electric power to actuate to fix or swing the locking part, and cooperate with the contraction of the lock bolt to achieve access control. Among them, the cathode lock with "electromagnetic lock structure" is usually assembled and installed at the door frame, and the lock bolt is usually installed at the door leaf (Door leaf), and the lock bolt is usually a latch bolt (Latch bolt). limit.

In this technical solution, when the lock tongue (not shown in the figure) is resisted by the lock piece to make the door closed and locked, under normal conditions, there may be a gap or space between the lock tongue and the lock piece, so the electromagnet ( When the coil) is energized and unlocked (not limited to this), there will be no preload (preload) between the lock tongue and the lock, that is, the ideal situation with the least friction resistance between the lock tongue and the lock , without affecting the action of the internal structure of the lock (because the locking piece is linked by the electromagnet), so the bolt is braked by the electrical operation of the electromagnet (coil), and the bolt can be pulled out or pulled out smoothly In addition to the locking parts, in order to achieve access control unlocking.

However, in special or common cases, such as after the cathodic lock is installed on the door frame and used for a long period of time, or because of natural disasters and earthquakes that destroy the entrance and exit of the home, there is a pre-compression between the deadbolt on the door leaf and the locking piece of the cathodic lock (preload) situation. That is, the structural deformation and dislocation between the door frame and the door leaf will cause the lock tongue to resist contact with the lock (keeper) and generate a preload (possibly tens of pounds), which may make the electromagnet electrically connected, but electrically connected. There is no gap or space in the linkage of the mechanical structure after passing (because the locking part is linked by the electromagnet). Therefore, when the lock bolt resists contact with the locker (keeper) to generate a preload, it may not be possible to directly unlock the door through the electrical connection of the electromagnet. Even in another case, it is only due to the preload situation caused by the lack of correct position and corresponding assembly between the lock bolt on the door leaf and the lock (keeper). Every time the operator performs the unlocking action of the access control, he needs to move the door leaf back and forth to release the preloading situation, which will cause inconvenience in operation after long-term use. The cathode lock structure of the similar type shown in Fig. 3 in the "Electric Control Lock" of Chinese Patent No. M250013 may all have such a preload situation.

Therefore, how to improve the deficiencies discussed above is the technical difficulty that the applicant in this case wants to solve.
