Technical Field
The invention relates to an emergency escape door opening device for public buildings, in particular to an emergency escape door opening device for medical clean plants.
Background
The emergency escape doors are installed in the medical clean factory buildings according to fire regulations, and the emergency escape doors are generally provided with flat push type emergency escape locks. When an emergency occurs, indoor personnel push the cross rod of the emergency escape lock outwards, the door is opened at the moment, and the personnel evacuate outwards in an emergency. The door is kept closed at ordinary times, so that people cannot enter and exit at will. However, the medical clean factory building needs to disinfect rooms according to the operation flow, including wiping with disinfectant for emergency escape locks, and actuating a cross rod of the escape locks in the wiping process; also, during production, it may happen that personnel or objects inadvertently touch the crossbar of the escape lock, which opens the door. A large amount of dirty air which is not filtered enters the clean area after the clean room door is opened, the original clean environment of the clean area is destroyed, and medicines and medicine detection laboratories are polluted, so that medicines are scrapped and detection fails.
In view of this, it is necessary to devise a delayed opening device for inadvertently striking the escape lock rail while simultaneously enabling the safety and rail to be activated during emergency evacuation without affecting the door.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a device capable of effectively preventing an escape door lock from being opened accidentally.
According to the technical scheme provided by the invention: an accidental opening prevention device for an escape door of a medical clean factory building is characterized in that,
the opening device comprises an escape door lock and a braking device;
the escape door lock comprises an escape lock body, a cross rod and a lock tongue; the escape lock body is fixed on the door, the cross rod is arranged on the outer side of the escape lock body, and a groove is formed between the cross rod and the escape lock body; pushing the cross rod to control the lock tongue to retract, so as to realize the opening of the door;
the brake device comprises a handle and a brake rod, when the brake device is in an upright state, the brake rod is embedded in the groove, and the handle is positioned in the middle of the brake rod and is in an outward protruding structure;
when the handle is in an upright state, the brake rod is parallel to the plane of the groove, the cross rod cannot be pushed to start the lock tongue, and the escape door is in a locking state;
when the handle is pushed outwards, the handle falls down vertically, and when the brake lever is in a vertical state with the groove, only the thickness part of the brake lever is embedded into the groove in the groove to push the cross rod, and the cross rod can be pushed outwards in the residual space of the groove, so that the starting of the lock tongue is realized, and the door is in an open state.
As a further improvement of the invention, the length of the groove is L, the length of the brake rod is D, and L-20mm is less than or equal to D and less than or equal to L.
As a further improvement of the invention, the handle length is M, M is controlled to be 120+/-20 mm, and H is controlled to be 60+/-10 mm.
As a further improvement of the invention, the braking device is made of steel.
Compared with the prior art, the invention has the advantages that: the invention has smart structure and simpler installation mode, and the brake device is embedded in the groove in front of the cross rod and the escape lock body, so that the door lock opening caused by touching the cross rod is effectively controlled, the environmental sterility of a medical clean factory building is more effectively protected, and the important isolation function is played for controlling the quality of medicines.

Detailed Description
The invention will be further described with reference to the following specific drawings and examples.
As shown in fig. 1-6, an accidental opening prevention device for an escape door of a medical clean factory building comprises an escape door lock and a brake device 3;
the escape door lock comprises an escape lock body 5, a cross rod 4 and a lock tongue 6; the escape lock body 5 is fixed on the door, the cross rod is arranged at the outer side of the escape lock body, and a groove 7 is formed between the cross rod 4 and the escape lock body 5; pushing the cross rod to control the lock tongue 6 to retract, so as to realize the opening of the door; the common escape lock pushes the cross rod, the lock tongue can retract, and the door is in an open state;
the brake device 3 comprises a handle 1 and a brake rod 2, when the brake device is in an upright state, the brake rod 2 is embedded in the groove 7, and the handle 1 is positioned in the middle of the brake rod 2 and is in an outward protruding structure;
when the handle is in an upright state, the brake rod 2 is parallel to the plane of the groove, the cross rod cannot be pushed to start the lock tongue 6, and the escape door is in a locking state;
when the handle 1 is pushed outwards, the handle 1 falls down vertically, and the brake rod 2 is in a vertical state with the groove, only the thickness part of the brake rod is embedded into the groove in the groove to push the cross rod, and the cross rod can be pushed outwards in the residual space of the groove, so that the starting of the lock tongue is realized, and the door is in an open state.
As a further improvement of the invention, the length of the groove is L, the length of the brake rod is D, and L-20mm is less than or equal to D and less than or equal to L.
As a further improvement of the invention, the handle length is M, M is controlled to be 120+/-20 mm, and H is controlled to be 60+/-10 mm.
As a further development of the invention, the braking device 3 is made of steel.
The specific implementation process comprises the following steps: after the device is embedded into the groove, the cross rod of the escape lock cannot move into the escape lock body, so that the escape lock is prevented from being opened. When an emergency occurs, people who evacuate outwards push the handle on the device for preventing accidental opening by hands in the direction of opening the door, the device falls down, the arrow is the direction inwards from the paper surface, as shown by the arrow direction pushing the handle in fig. 4, the escape lock cross bar is not subjected to any outward force of the body after the escape lock cross bar is protected, so that the escape lock cross bar moves outwards simultaneously, the escape lock is opened, the door is opened and the people evacuate outwards, and the two actions are completed simultaneously without affecting the delayed opening of the door.
