Description

Door lock structure with fireproof parts

This invention is a door lock structure with fireproof parts, especially a door lock structure that can cover the door hole by configuring fireproof elements in the lock, thereby blocking the spread of fire and reducing the temperature transfer rate, which can help to gain time for escaping from the fire and effectively improve the safety of escaping from the place.

With the increasing requirements for safety and fire resistance in modern buildings, the fire resistance of locks has become an important factor that cannot be ignored. When a fire occurs, the locks must be able to maintain their structural integrity in a high temperature environment to avoid escape difficulties or property losses caused by lock failure. Therefore, the fire resistance of modern locks is not only an important component of building fire protection design, but also one of the key factors in protecting human life and property safety.

Fireproof locks need to have key properties such as high temperature resistance, flame retardancy and structural stability. Among them, high temperature resistance requires that the locks can effectively retard fire sources in high temperature environments, which is crucial for escape and preventing the spread of fire.

As for the standards of fireproof locks, each country has its own strict specifications. For example, the European EN 1634 standard stipulates that fireproof locks must withstand temperatures above 1,000°C for more than 60 minutes without failure. The US UL 10C standard requires that in a fire simulation test, fireproof doors and their locks must withstand a combustion test in a high-temperature flame for at least 20 minutes to 3 hours. The test process simulates the high-temperature environment of a real fire, with the highest temperature reaching 927°C (1700°F) or more, and the lock must maintain its structural integrity and functionality in this environment without deformation or failure. In addition, the material of the lock parts must also meet the conditions of not spontaneous combustion and must effectively prevent the fire from igniting during the test process. Isolate the fire source and prevent the flame from spreading through the door installation hole to another safe space and expanding the scope of the fire. Therefore, under the relevant strict standard test, in addition to ensuring the safety of fire prevention, it can also provide consumers with reliable safety guarantees. And for buildings, especially home environments, public places or high-rise buildings, it is particularly important to choose locks that meet fire protection standards. It can significantly improve the safety level of the entire building and provide a safer environment for all residents or users.

Most of the locks today are made of metal. Although they can cover the door holes on both sides of the door body during installation, metal is usually only resistant to high temperatures and has limited fire protection performance. There is no mechanism to provide fire protection shielding for the door holes, so the flame will still spread through the door holes to the other side. In addition, metal has high thermal conductivity, so it cannot effectively achieve the effect of temperature isolation. All of these will lead to failure to meet relevant fire protection standards and raise safety concerns.

First, please refer to Figures 1 to 3. This invention is a door lock structure with fireproof parts, which includes:

A lock 1, in one embodiment, can be an auxiliary lock, a cylindrical lock, a tubular lock, a flat handle lock or an electronic lock, but it is only an example and is not limited to this; and the configuration of the lock 1, in one embodiment, in order to achieve its fire prevention, fire source blocking, and anti-spreading requirements, the whole or at least part of the parts can be set with a non-self-igniting material; and the specific configuration of the lock 1 is to be provided with an outer lock body assembly 11, an inner lock The outer lock body assembly 11 and the inner lock body assembly 12 are provided with a transmission component 14, 14' respectively, and the transmission components 14, 14' are directly or indirectly mutually transmitted and are correspondingly assembled and transmitted to the bolt assembly 13, so that the bolt assembly 13 is correspondingly driven to be in an unlocked state or a locked state through the transmission components 14, 14' for linkage;

The lock 1 is used to be installed on a door body 2, and the door body 2 can preferably be a fireproof door with fireproof requirements; the door body 2 can be unlocked or locked by the bolt assembly 13 as mentioned above, so as to lock the door body 2; the door body 2 is provided with a door hole 21, and the side edge of the door body 2 is provided with a bolt hole 22 corresponding to and vertically connected to the door hole 21; the outer lock body assembly 11 and the inner The side lock assembly 12 is respectively arranged on both sides (i.e., the outer side and the inner side) of the door body 2, and the bolt assembly 13 is correspondingly assembled in the bolt hole 22; and the transmission components 14, 14' are mutually transmission-assembled through the door hole 21, and correspondingly transmitted to the bolt assembly 13; and it can be known that the bolt assembly 13 is provided with a transmission component 131, so that the transmission components 14, 14' can be correspondingly assembled and transmitted; and

For example, the size of the through hole 31 is substantially the same as the space required for the transmission components 14, 14' to rotate, so that the transmission components 14, 14' can still rotate smoothly when extending therethrough.

Thus, the invention can achieve the effect of blocking the fire source and smoke by directly placing the fireproof element 3 in the door hole 21, or by directly or indirectly contacting to at least partially cover the inner side or outer side of the door hole 21, or by respectively setting it on both sides of the door body 2, so as to make it possible to achieve the effect of blocking the fire source and smoke, so that when a fire occurs on one side of the door body 2, when the flame and smoke spread to the door hole 21, in addition to the initial fire source blocking by the fireproof property of the lock 1 itself, the fireproof element 3 can also block the flame, so that the flame cannot burn, and the flame and smoke cannot spread through the fireproof element 3. In addition, the fireproof element 3 can also greatly reduce the convection of air from the other end through the door hole 21 to the end where the fire occurs, so as to help reduce the probability of its spreading;

In a preferred embodiment, which is the first embodiment shown in FIGS. 1 to 3, the lock 1 of the first embodiment is configured as an electronic lock, and the positioning configuration of the fire protection element 3 is preferably further including a lock plate 4, which is correspondingly assembled to the outer lock body assembly 11 or the inner lock body assembly 12, and in this embodiment, it is configured at one end of the inner lock body assembly 12; the lock plate 4 is correspondingly abutted against the door body 2, and the fire protection element 3 is correspondingly adjacent to the lock plate 4; the lock plate 4 is provided with a through hole 41 corresponding to the through hole 31, so that the transmission components 14, 14' can be correspondingly penetrated and transmitted.

Please refer to Figures 6 and 7, which are the fourth embodiment of the present invention. The lock 1 in this embodiment is configured as a handle-type electronic lock. In this embodiment, the fireproof element 3 is configured at one end of the outer lock body assembly 11, and the lock plate 4 is not configured. The fireproof element 3 is directly configured in the door hole 21, so that when the outer lock body assembly 11 is positioned on the door body 2, the fireproof element 3 can be positioned and can be placed against the side end of the bolt assembly 13, and is positioned by the clamping between the outer lock body assembly 11 and the bolt assembly 13.
