Description
Technical Field
The utility model relates to the technical field of evacuation doors, in particular to an evacuation automatic door with a movable fan locking function.
Background
The automatic evacuation door is normally used as a smooth door to slide and open and close, and when evacuation needs exist, the movable fan and the fixed fan can be pushed open to 90 degrees so as to achieve the maximum passing width. When the evacuation door is used as a smooth door for most of the time, the movable fan and the fixed fan are required to be in a closed state, and only smooth movement is required. The traditional evacuation door generally has no door locking function, and has the following problems: the automatic evacuation door, especially in public places, often cannot ensure that the door leaf is in a perfect closing state due to misoperation of personnel or wind pressure action in the indoor and outdoor, so that the movable fan and the fixed fan of the automatic evacuation door are damaged by rubbing, and security and management in public places are also influenced. The reason why the conventional evacuation door generally does not have a door locking function is that: 1. the movable door leaf of the evacuation door is in a motion state and needs related mechanisms to supply power to the movable door leaf. 2. Because of the special purpose of the evacuation door, the requirement on the lock is high, and when a lock plate is required to have certain pressure on the lock tongue (the pressure is generally caused by misoperation or wind pressure of personnel), the lock tongue can still be retracted to unlock the door. And the common locks such as electric mortise locks and shear locks can not be normally unlocked under pressure through testing, so that potential safety hazards of incapacity of evacuation are caused. Therefore, the evacuation door can be locked, and simultaneously can be automatically unlocked when evacuation is needed, so that the evacuation door is a problem to be solved.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides an automatic evacuation door with a movable fan locking function.
The technical scheme of the utility model is as follows: the utility model provides an evacuation automatic door with a movable fan locking function, which comprises: the electric door lock comprises a drag chain structure, an electric push rod mechanism, a lock tongue and a lock plate, wherein the drag chain structure is arranged inside a door machine, the electric push rod mechanism is arranged inside an upper cross beam of a movable fan, the lock tongue is arranged on a push rod of the electric push rod mechanism, the lock plate is arranged on an upper cross frame of the movable fan, a circuit is electrically connected with the electric push rod mechanism through the drag chain structure, and the electric push rod mechanism can drive the lock tongue to be inserted into or separated from a hole of the lock plate.
Further, the lock plates are all located in the upper transverse frame.
By adopting the scheme, the utility model has the beneficial effects that: the automatic evacuation door locking mechanism can realize the locking function of the automatic evacuation door, is matched with a standby power supply, and can automatically unlock under a fire-fighting signal or other door opening signals even under the condition of power failure of the commercial power, and evacuation personnel can directly push away the evacuation door leaves to realize the evacuation function. The high thrust of the electric push rod is utilized to realize automatic unlocking of the movable fan of the evacuation door, the problems of product damage and security caused by the fact that the automatic evacuation door is opened due to misoperation or wind pressure are solved, and the potential safety hazard caused by the fact that the movable fan of the traditional automatic evacuation door is blocked due to the fact that the conventional lock is adopted by the movable fan of the evacuation door due to the fact that the thrust of a lock tongue is insufficient is avoided, and then the movable fan cannot be pushed to evacuate is avoided.

Detailed Description
The utility model will be described in detail below with reference to the drawings and the specific embodiments.
Referring to fig. 1 and 2 in combination, in this embodiment, the present utility model provides an evacuation automatic door with a movable fan locking function, including: the electric door lock comprises a drag chain structure 1, an electric push rod mechanism 2, a lock tongue 3 and a lock plate 4, wherein the drag chain structure 1 is arranged inside a door machine 100, the electric push rod mechanism 2 is arranged inside an upper cross beam 200 of a movable fan, the lock tongue 3 is arranged on a push rod of the electric push rod mechanism 2, the lock plate 4 is arranged on an upper cross frame 400 of the movable fan 500, a circuit is electrically connected with the electric push rod mechanism 2 through the drag chain structure 1, and when the electric door lock is used, the electric push rod mechanism 2 is controlled through an external circuit, so that the electric push rod mechanism 2 can drive the lock tongue 3 to be inserted into or separated from a hole of the lock plate 4, and the functions of locking and unlocking the movable fan are realized.
Further, the lock plates 4 are all located in the upper transverse frame 400, so that the lock plates 3 are hidden in the upper transverse frame 400, and the consistency and the aesthetic property of the appearance of the door leaf are ensured.
In summary, the beneficial effects of the utility model are as follows: the automatic evacuation door locking mechanism can realize the locking function of the automatic evacuation door, is matched with a standby power supply, and can automatically unlock under a fire-fighting signal or other door opening signals even under the condition of power failure of the commercial power, and evacuation personnel can directly push away the evacuation door leaves to realize the evacuation function. The high thrust of the electric push rod is utilized to realize automatic unlocking of the movable fan of the evacuation door, the problems of product damage and security caused by the fact that the automatic evacuation door is opened due to misoperation or wind pressure are solved, and the potential safety hazard caused by the fact that the movable fan of the traditional automatic evacuation door is blocked due to the fact that the conventional lock is adopted by the movable fan of the evacuation door due to the fact that the thrust of a lock tongue is insufficient is avoided, and then the movable fan cannot be pushed to evacuate is avoided.
The foregoing description of the preferred embodiment of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
