Key hole protection device for intelligent lock

Abstract

The invention relates to the technical field of intelligent locks, and discloses a key hole protection device for an intelligent lock. The key hole protection device comprises a key hole face board and a cover plate, wherein sliding grooves A are formed in the two sides of the front face of the key hole face board correspondingly, sliding rods A are fixedly connected to the top faces of the sliding grooves A, lantern rings are connected with the outer walls of the sliding rods A in a sleeving mode, and the two sides of the back side face of the cover plate are fixedly connected with the two lantern rings correspondingly. Through the arrangement of the cover plate, a key hole is automatically closed when the intelligent lock is used, so that the key hole is and protected; the cover plate isfixed through limiting blocks, so that the problem that the cover plate is unfolded due to mistaken touch is avoided; the key hole is automatically unfolded after a circuit board of the intelligent lock is powered off, so that the effect of reminding a user that the intelligent lock is powered off is achieved; and during a fire disaster, when the circuit board of the intelligent lock is powered off due to the fire disaster, the problem that time is wasted when the user searches for the position of the key hole and opens the cover plate can be solved, so that the door opening speed of the useris increased, and the speed of the user escaping from the dangerous environment is accelerated under the condition of every minute counts.

Description

technical field [0001] The invention relates to the technical field of intelligent locks, in particular to an intelligent lock key hole protection device. Background technique [0002] Smart locks are improved on the basis of being different from traditional mechanical locks. They do not use keys to unlock, but use various methods such as fingerprint unlocking or door card unlocking. In order to avoid a fire, there is no smart lock equipped with a mechanical lock cylinder If the failure or the melting of the main control board prevents the escape door from being opened, the smart lock will still be equipped with a keyhole. [0003] The existing patent No. CN104727663B proposes an intelligent door lock, which has the characteristics of simple structure and various functions, but it does not install a protective device on the keyhole to hide and protect it, and the thief can directly lock the lock cylinder through the keyhole. Operation, resulting in the problem that the anti...

[0003] The existing patent No. CN104727663B proposes an intelligent door lock, which has the characteristics of simple structure and various functions, but it does not install a protective device on the keyhole to hide and protect it, and the thief can directly lock the lock cylinder through the keyhole. operation, resulting in the reduction of the anti-theft ability of the door lock, and the key hole is directly exposed to the outside world, which cannot prevent the entry and erosion of flying dust, insects and water vapor

[0004] The protection measures of the existing intelligent lock keyhole protection device are relatively simple, and any group of people can easily open it, and the anti-theft ability is still weak. However, after the protection device with a fixed mechanism fails to use the intelligent control system due to a fire, the user needs to When escaping from a dangerous environment, it takes time to open the fixing mechanism, which delays the time for the user to escape from the dangerous environment
