Problems solved by technology

However, the setting of the door closer has also caused a relatively obvious defect: the door opener needs to apply a large force to open the door leaf of the fire door. For some special groups of people, such as children, the elderly, or people with disabilities ( Wheelchair) and other personnel, because of their weak strength, are often unable to push open the existing fire doors alone or quickly, resulting in potential safety hazards in the use of fire doors

Embodiment 1

[0036] refer to Figure 1-2 , an evacuation fire door suitable for people with disabilities, comprising a door frame 1 and a door leaf 2, the door leaf 2 is embedded and hingedly arranged on the door frame 1 to form an openable and closable structure, and the evacuation fire door also includes a door closer 3, The door closer 3 includes:

[0037] The main housing 6 is fixed on the door frame 1. The main housing 6 is provided with a hollow cavity 7 and a sealed cavity 8 which communicate with each other on the left and right. The hollow cavity 7 is filled with hydraulic oil. The upper end of the main housing 6 is provided with a return channel 13 communicating with the left and right sides of the hollow cavity 7; The right end device of the piston 9 has a back-moving spring 10; the left side of the piston 9 is provided with a corresponding rack, and the top of the piston 9 is connected with a gear shaft 12 through the gear rack engagement rotation, and the gear shaft 12 is con...

Embodiment 2

[0052] refer to Figure 4 The difference between this embodiment and the first embodiment lies in that: the person identification module is an infrared sensor, and the infrared sensor is fixedly arranged below the middle part of the door frame 1 . The identification process is as follows: when the infrared sensor is not blocked by a passing person, it is judged as No; when the infrared sensor is blocked by a passing person, it is judged as Yes.

[0053] It should be pointed out that the realization principle and the technical effect produced by this embodiment are the same as those of the first embodiment. For the sake of brief description, for the parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

Embodiment 3

[0055] refer to Figure 5 The difference between this embodiment and the first embodiment is that: the person recognition module is a camera, and the camera is fixedly arranged below the middle part of the door frame 1 . The identification process is as follows: when the camera does not capture a person passing by, the judgment is no; when the camera captures a person passing by, the judgment is yes.

[0056] It should be pointed out that the realization principle and the technical effect produced by this embodiment are the same as those of the first embodiment. For the sake of brief description, for the parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

Abstract

The invention relates to an evacuation fireproof door suitable for disabled people and a using method thereof.The evacuation fireproof door comprises a door frame and a door leaf, the door leaf is embedded in the door frame in a hinged mode to form an openable and closable structure, and the evacuation fireproof door further comprises a door closer; the door closer comprises a main shell, a reset spring, a piston, a gear shaft, a flow promoting mechanism and a pressure promoting mechanism. By controlling opening and closing actions of a one-way electromagnetic valve of a flow promoting mechanism and an electromagnet of a pressure promoting mechanism in the door closer, on the basis of ensuring automatic closing of the fireproof door, circulation resistance of hydraulic oil can be safely and stably relieved, compression of a reset spring is accelerated, and therefore acting force needed by a user to open the door is relieved, and the safety of the fireproof door is improved. By means of the fireproof door, the door leaf can be conveniently and rapidly opened by people with small strength such as children, old people or patients, and therefore on the basis that the fireproof effect is not affected, the people with small strength can effectively and conveniently open and pass through the fireproof door.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a fire door suitable for evacuation of people with disabilities and a use method thereof. Background technique [0002] Existing fire doors for evacuation generally include a door frame, a door leaf, and a door closer connected between the door frame and the door leaf. The door closer is set to ensure that the door leaf is always in a closed state, thereby effectively forming a fire prevention effect. However, the setting of the door closer has also caused a relatively obvious defect: the door opener needs to apply a large force to open the door leaf of the fire door. For some special groups of people, such as children, the elderly, or people with disabilities ( Wheelchair) and other personnel, because of their low strength, often cannot push the existing fire doors alone or quickly, resulting in potential safety hazards in the use of fire doors. [0003] Therefore, on the ba...
