Device and method for guaranteeing fire-resistant integrity of intelligent door lock

Abstract

The invention discloses a device and method for guaranteeing fire-resistant integrity of an intelligent door lock, the device comprises a front panel, a rear panel and a lock body, the front panel is fixed on a door through a mounting iron plate and a fireproof liner by a connecting screw, the rear panel is fixed on the mounting iron plate, the lock body is fixedly mounted in the door, and the mounting iron plate and the fireproof liner are provided with mounting screw via holes. The handle square shaft through hole and the knob through hole ensure that the rear handle, the lock cylinder knob and the safety tongue knob on the rear panel are respectively connected with the lock body and the lock cylinder, and a movable gap value is kept. The intelligent lock is novel in structural design, good in fire resistance, high in safety and long in service life, the fire and smoke mixing phenomenon is avoided, it is guaranteed that key structural parts of the lock body are not damaged or invalid, and it is guaranteed that fire-resistant integrity of the intelligent lock is achieved.

Description

technical field [0001] The invention relates to the technical field of fire protection of intelligent locks, in particular to a device and method for ensuring the fire resistance integrity of intelligent door locks. Background technique [0002] Nowadays, the intelligent fire locks on the market generally have the problem of substandard fire resistance integrity, which directly leads to the inability of the anti-theft door to be opened in the event of a fire alarm, which involves major problems of escape inside the door and external rescue. It is mainly manifested in the case of fire in the house, because the intelligent lock surface softens or deforms and falls off at high temperature, resulting in the loosening of the fastening screws that fasten the intelligent lock panel outside the door, causing the body of the intelligent lock panel outside the door to fall off. Is the lock panel in a loose and detached state? The fire will follow the handle square shaft hole, the lock...

Problems solved by technology

[0002] Nowadays, the smart fireproof locks on the market generally have the problem of substandard fire resistance integrity, which directly leads to the inability to open the security door in case of fire, which involves major problems of escape inside the door and external rescue.

Its main manifestation is that in the case of a fire in the house, because the smart lock shell softens or deforms and falls under high temperature, the fastening screws that fasten the smart lock panel outside the door loosen, causing the smart lock panel outside the door to fall off. Is the lock panel in a loose and falling state? The fire will follow the square shaft hole of the handle, the lock cylinder hole, and the gap between the screw fixing holes (chimney effect). The key parts of the key parts of the lock body cannot withstand the high temperature. High temperature produces deformation and failure, resulting in the loss of lock body function and the door cannot be opened
