Description

Lock structure capable of pre-pressing and unlocking

This creation is about a lock, especially a lock structure that can be unlocked normally in a preload state.

The door lock, as the name implies, is a device used to lock the door to prevent others from opening the door. Different from traditional mechanical locks, electronic locks or electronically controlled locks are more intelligent and simpler in terms of user safety, identification, and management.

Please refer to the first picture. It is a conventional electronic lock. The lock is installed on the door frame and needs to be used with a mechanical lock box. The mechanical lock box has a bolt and is installed on the door leaf ( Door leaf). And, under normal circumstances, the bolt is a diagonal bolt, and a square bolt is not suitable.

Please refer to the second figure, the lock includes a base 100, a chamber 200, a pivotable first limiting member 300, a second limiting member 400, a driving member 500 and a pivotable A stopper 600. Wherein, one end of the first limiting member 300 is provided with a compression spring 310 and a first groove 320, the other end of the first limiting member 300 is provided with a first protrusion 330; the second limiting member 400 is provided with a first Two grooves 410; the driving member 500 is a solenoid valve, the driving member 500 is provided with a movable iron core 510 (as shown in the third figure) that can reciprocate back and forth, the movable iron core 510 is connected to the second limit The positioning member 400 enables the second limiting member 400 to act with the movable iron core 510; one end of the stopping member 600 is provided with a stopper 610. The stopper 610 is located in the chamber 200, and a second protrusion 620 is provided at the other end of the stopper 600.

Please refer to the second figure again. If the lock is energized to unlock and power off to lock, when the lock is in the power off and locked state, the lock tongue (not shown) squeezes the stopper 600 and Entering the chamber 200, because the first protrusion 330 of the first limiting member 300 is caught in the second groove 410 of the second limiting member 400, the pivot of the first limiting member 300 is caused. The rotation is restricted by the second limiting member 400. Moreover, the second protrusion 620 of the stopper 600 is caught in the first groove 320 of the first stopper 300, causing the pivoting of the stopper 600 to be held by the first stopper 300. Therefore, the stopper 610 of the stopper 600 can block the lock tongue and prevent the lock tongue from leaving the chamber 200.

Please refer to the third figure. When the lock is energized and unlocked, the driving member 500 is energized to actuate the movable iron core 510, and the movable iron core 510 drives the second limiting member 400 to act, causing the first limiting member 400 to act. The first protrusion 330 of the positioning member 300 disengages from the second groove 410 of the second limiting member 400, so that the elastic force of the compression spring 310 of the first limiting member 300 causes the first limiting member 300 to rotate, causing The second protrusion 620 of the stopper 600 disengages from the first groove 320 of the first stopper 300. Since the restriction of the pivoting of the stopper 600 is released, the lock tongue can be separated from the chamber 200 , Complete unlocking.

The above is the normal operation mode of the lock. However, under certain conditions (such as old door leaf, natural disasters, earthquakes, fire, inaccurate installation of the lock), the lock will be preloaded due to a load force in advance. , Causing the original gap between the lock tongue and the stopper 600 to be eliminated, causing the lock to fail to operate normally, that is, it cannot be unlocked smoothly. Preload refers to the pre-applied load force (referring to the external force acting on the object) to eliminate the gap. The preload will cause the gap between the lock tongue and the stopper 600 to be eliminated, so that the lock tongue It "bites" tightly with the stopper 600.

For example, if the door leaf is old, the door leaf will lean against the door frame, or natural disasters and earthquakes destroy the entrance and exit of the home, causing structural deformation and dislocation between the door frame and the door leaf, which may cause the lock tongue to resist contact with the stopper 600. Withstand the load (maybe tens of pounds) and produce a pre-compression state.

Another example is a fire. People will run away from the indoor to the outdoor shack, push the door irrationally, and exert excessive load on the door, resulting in a preload state.

Please refer to the second figure again. If the lock is in a pre-compressed state, the stopper 600 is resisted and touched by the lock tongue, causing the second protrusion 620 of the stopper 600 to be clamped to the first stopper The first groove 320 of 300. Similarly, the first protrusion 330 of the first limiting member 300 is clamped to the second groove 410 of the second limiting member 400, which affects the operation of the internal structure of the lock As a result, although the driving member 500 can be electrically connected (energized), the linkage of the mechanical structure after the electrical connection has no gap or space to act. In addition, the drive member 500 is a solenoid valve. The solenoid valve uses a coil to generate a magnetic force to attract the movable iron core 510 to reciprocate back and forth. Therefore, the force of the solenoid valve is extremely small, and the force of the solenoid valve is insufficient to drive the pre-pressure state The stopper 600. Therefore, when the lock is in the pre-compressed state, it cannot be opened normally by the electrical connection (energization) of the driving member 500 directly.

In another case, the lock tongue on the door leaf and the stopper 600 are not in the correct position due to the incorrect installation of the lock, causing the position to be mismatched, resulting in a pre-compressed state. This situation is not that the lock cannot be unlocked normally. Every time the lock is unlocked, the door leaf needs to be pushed back and forth to release the preload state, which may cause inconvenience in operation after long-term use.

Therefore, when the conventional electronic lock is in a pre-compressed state, it cannot be opened normally by the electrical connection (energization) of the driving member 500 directly. How to improve on the above mentioned deficiencies is the technical difficulty that the applicant intends to solve.

In view of the above, the purpose of this creation is to solve and improve the problems and deficiencies in the traditional use.

In order to achieve the above objectives, this creation provides a lock structure that can be preloaded and unlocked, which includes: a base, at least one stopper, at least one first limiter, at least one second limiter, and at least one Drive. The base is provided with an accommodation chamber which communicates with an opening; the at least one stopper is pivoted on the accommodation chamber and located at the opening; the first limiter is pivoted on the base, the first The limiting member abuts against the stopping member to limit the pivoting of the stopping member; the second limiting member is pivoted on the base, the second limiting member is close to but not touching the first limiting member, And restricting the pivoting of the first limiting member; and the driving member is arranged on the base, the driving member drives the second limiting member, the restriction on the first limiting member is released, and the first limiting member is driven Limit piece, and lift the restriction on the stop piece.

Preferably, the at least first limiting member has an L-shaped bent shape, one end of the first limiting member is provided with a detent portion, and the other end is provided with a pushed portion, and the detent portion abuts against the stopper.
