Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a new and more stable electric lock. Background Art

[0002] A lock refers to a device that serves a sealing function, which includes locks, keys and their accessories. It is generally interpreted as a seal that can only be opened with a key. In addition to being opened with a key, a lock can also be opened with light, electricity, magnetism, sound, fingerprint and other commands. Locks are not only protective equipment, but also have management and decorative functions.

[0003] For example, the patent with publication number CN215332051U discloses a new and more stable electric lock, including a metal shell, wherein solar panels are respectively embedded and installed on the front and rear surfaces of the metal shell, a fingerprint recognition module is embedded and installed on the front surface of the metal shell, a lock core is inserted into the front surface of the metal shell, a movable locking rod is inserted into the interior of the metal shell near the upper surface, a movable locking pin is movably installed in the interior of the metal shell below the movable locking rod, and a spring is fixedly installed on the lower surface of the movable locking pin.

[0004] Through the above settings, a new and more stable electric lock described in the prior art can use fingerprint recognition and keys to unlock at the same time, and the two do not interfere with each other. It can be unlocked when the key is forgotten or the battery is low, which improves the stability of use. The lock can be powered by solar energy without external power supply, which improves the convenience of use. However, the more stable electric lock of the prior art solution has the following defects during operation:

[0005] In the above device, when the battery power is low, the key is used to rotate the lock cylinder, so that the lock cylinder drives the fixed rack to move downward. The rack moves downward and drives the movable rack to move downward. The movable rack will drive the driving gear and the worm gear to rotate. Because the worm gear cannot drive the driving worm to rotate, the driving worm gear and the driving worm will conflict with each other, making the lock cylinder unable to rotate, thereby failing to achieve the purpose of unlocking. Utility Model Content

[0006] The utility model aims to provide a new and more stable electric lock, which is mainly used to solve the technical problem in the prior art that the lock cannot be unlocked by a key.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A new and more stable electric lock comprises a metal shell, a fingerprint recognition block is fixedly connected to the front end of the metal shell, a lock core is rotatably connected to the front end of the metal shell, a rectangular through hole is opened on the top of the metal shell, a circular slide groove is opened at the bottom of the rectangular through hole, and the circular slide groove is connected to the rectangular through hole, a movable rod is slidably connected to the inner side wall of the circular slide groove, a rectangular block is fixedly connected to the top of the movable rod, the rectangular block is slidably connected to the inner side wall of the rectangular through hole, a connecting groove is opened on the outer side wall of the metal shell at the movable rod, a card slot is opened on the lower end side wall of the movable rod, a rectangular groove is opened at the bottom of the connecting groove, a cavity is opened at the bottom of the rectangular groove, a spring is symmetrically fixedly connected to the bottom of the rectangular groove, a moving plate is fixedly connected to the top of the spring, the moving plate is slidably connected to the inner side wall of the rectangular groove, a card block adapted to the card slot is fixedly connected to the top of the moving plate, an adjustment component is fixedly connected to the bottom of the moving plate, and a power component is fixedly connected to the bottom of the cavity.

[0010] 1. Working principle: The more stable electric lock structure in the utility model is similar to the existing more stable electric lock structure, such as a new more stable electric lock disclosed in the patent with publication number CN215332051U. The main improvement of the utility model is that when the device needs to be locked, the user pushes the rectangular block by hand, so that the rectangular block drives the movable rod to move along the inner wall of the circular slide groove toward the connecting groove. As the movable rod moves, when the end of the movable rod just contacts the card block, the movable rod will resist the card block, so that the card block moves downward through the movable plate. At this time, the spring is compressed. When the card block coincides with the card slot, under the action of the compression spring, the movable rod is locked. The moving plate drives the card block to move upward along the inner wall of the rectangular groove to realize the card connection between the card block and the card slot and complete the locking. When unlocking is required, the user can press the finger on the position of the fingerprint recognition block, and the fingerprint recognition module can recognize the entered fingerprint, and then the information is fed back to the control chip. After comparing the composite unlocking conditions, the control chip will send a signal to the power component, and the power component will drive the adjustment component to work. When the adjustment component works, it will drive the moving plate to move downward along the inner wall of the rectangular groove, thereby achieving the purpose of unlocking. When it is necessary to unlock with a key, the key can be inserted into the inside of the lock core to directly make the adjustment component work and achieve key unlocking.

[0011] 2. Beneficial effects:
