Description

Technical Field

[0001] The present invention relates to the technical field of mechanical lock cores, and particularly to a management device for mechanical lock cores of electronic locks in public places. Background Technique

[0002] In the public rental housing industry, electronic locks are widely used. Common ones include card-swipe hotel locks, fingerprint password locks used in apartments and rental houses, etc. Due to the high failure rate of electronic devices, mechanical lock cores are retained for emergency use.

[0003] Mechanical lock cores are prone to being opened by technical means, mechanical keys are easy to copy, and there are potential safety hazards such as the inability to locate the unlocking personnel. It is necessary to additionally add a function of unlocking by face recognition with a camera on the lock. Moreover, spare mechanical lock cores and mechanical keys can be freely copied by locksmith shops. Therefore, we introduce a management device for mechanical lock cores of electronic locks in public places. Summary of the Invention

[0005] To achieve the above purpose, the present invention provides the following technical solution: A management device for mechanical lock cores of electronic locks in public places includes a lock body and a handle installed on the lock body. A lock core is installed at the lower end inside the lock body, and a push rod is connected to the lock core rod at the top of the lock core.

[0006] A locking mechanism is provided inside the lock body above the lock core. The locking mechanism includes a box body, an electromagnet located on the left side inside the box body, and a slider located at the central position inside the box body.

[0007] Above the electromagnet, a magnet and a ball are arranged in sequence. A locking slider is arranged on the upper right side of the ball. A return spring is arranged on the left side of the locking slider. Below the lower right side of the locking slider, a self-locking top block and a spring are arranged in sequence. The upper end of the push rod extends into the box body, and the upper end of the push rod is located directly below the spring.

[0008] The slider is located above the right side of the self-locking top block. A limit seat is arranged after the upper end of the slider extends out of the box body. The limit seat is located directly below a pin, and a rotating block connected to the handle is located directly above the pin.

[0009] Compared with the prior art, the beneficial effect of the present invention is that when the present invention is working normally, the mechanical key needs to pass fingerprint, card or password verification before it can be used to unlock, avoiding potential safety hazards caused by the easy technical opening of mechanical lock cores and the easy copying of mechanical keys.
