Technical Field

The invention discloses a quick opening mechanism for a fire fighting access door, and belongs to the field of fire fighting.

Background

At present, a fire-fighting access door is a door which is arranged at an emergency escape exit of a building and can be opened quickly. The fire door can all be installed to the passway for escaping in large-scale underground square, and this door is in the closed condition at ordinary times, and is durable, and the leakproofness is good, and in case danger takes place underground, people can open the emergency exit from inside to flee. The existing evacuation door is characterized in that a wrench is pulled downwards manually, the other end of the wrench moves upwards, a button rod moves upwards, a connecting rod is driven to rotate clockwise, a pull rod head is driven to move leftwards, the pull rod head pulls a joint leftwards through a pull rod, a gear shaft and a lock tongue are driven to move leftwards simultaneously, the lock tongue is separated from a lock hole, the door is released and fixed, the door is opened, the manual structure cannot be opened rapidly when major accidents happen, certain reaction time is needed, every time the manual structure is delayed for a certain period of time, serious consequences can be caused, safety cannot be guaranteed, and therefore a fire fighting access door quick opening mechanism is needed at present.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a quick opening mechanism for a fire-fighting access door to solve the problems in the background art.

In order to achieve the purpose, the invention is realized by the following technical scheme: the invention relates to a quick opening mechanism of a fire fighting access door, which comprises a fire fighting access, wherein a fire fighting door is arranged on one side of the fire fighting access, a motor is fixedly arranged at the upper end of the inner side of the fire fighting access, an output shaft of the motor is movably connected with one end of a movable rod, a connecting plate is fixedly arranged on one side of the fire fighting door, the other end of the movable rod is connected with one side of the connecting plate, a sliding groove is formed in one side of the fire fighting access, a sliding block matched with the sliding groove is arranged on the inner side of the sliding groove, one side of the sliding block is movably connected with the connecting plate through a connecting shaft, and a telescopic device is.

Another embodiment of the invention is that the telescopic device comprises a fixed plate, one side of the fixed plate is connected with the outer side of the fire fighting channel, a first supporting block is fixedly installed on one side of the upper end of the fixed plate, a second supporting block is fixedly installed on the other side of the upper end of the fixed plate, a stop lever is inserted into the inner side of the second supporting block, one end of the stop lever is connected with one side of a movable block, a limiting groove is formed in the inner side of the movable block, an air cylinder is fixedly installed on one side of the upper end of the first supporting block, and the output end of the air cylinder is connected with a limiting column.

In another embodiment of the present invention, the limiting groove has an arc-shaped structure, and the limiting post and the limiting groove are matched with each other.

In another embodiment of the present invention, a temperature sensor and a smoke sensor are sequentially installed on one side of the motor and on the inner wall of the fire fighting tunnel.

In another embodiment of the present invention, the movable rod is connected to the connecting plate through a movable shaft.

the invention has the beneficial effects that:

1. According to the rapid opening device for the fire fighting access door, when a fire disaster occurs, the temperature and smoke in the fire fighting access can be sensed through the temperature sensor and the smoke sensor, and the fire fighting door can be opened timely and rapidly;

2. the fire-fighting door has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like, the common fire-fighting door is a left-right double-door or single-door, and the fire-fighting door is opened upwards, so that the fire-fighting channel is completely unblocked, and the blocking phenomenon cannot occur.
