Air pressure executive device with automatic locking buckling function

Abstract

Disclosed is an air pressure executive device with an automatic locking buckling function. The air pressure executive device comprises an air cylinder main shell, an air cylinder front cover body, an air push bock and an air cylinder movable rod. The air cylinder main shell is provided with an air push block holding chamber. The air cylinder front cover body is installed at one end of the air cylinder main shell in a seal covering mode and further comprises a first locking buckling assembly. The air push block is arranged in the air push block holding chamber. One end of the air cylinder movable rod is connected with the air push bock and penetrates through the air cylinder front cover body. When the air push bock is pushed, the air cylinder movable rod moves to be locked and buckled together with the first locking buckling assembly, and the air cylinder movable rod is locked and buckled and cannot move.

Description

technical field [0001] The invention relates to a cylinder technology, in particular to a pneumatic actuator with an automatic locking function, which can be fixed after being moved to a specific position, and can only be moved again through the opening of an air valve. Background technique [0002] Even though the development of air-conditioning equipment has been quite complete, the most effective way to adjust the temperature and humidity of the indoor space is to directly guide the outdoor air into the room through the window and exclude the indoor air to achieve a multi-functional adjustment effect. In addition, the windows can also provide enough light indoors. Compared with artificial lighting equipment, the outdoor light is not only natural, and the human eyes can adapt better, but also reduces energy consumption and electricity demand. Therefore, the development of architectural technology has never stopped installing windows. In addition to being an aesthetic desig...

Problems solved by technology

However, when a fire breaks out, time is very tight, and when every second counts, it is difficult for personnel to spare time to open the windows one by one, especially in large buildings, such as exhibition halls or factories, where the windows are often located beyond the reach of personnel. Not to mention opening, therefore, in case of fire, how to automatically open windows in time has become an important research direction for fire-fighting equipment

[0010] Automatic opening of windows is a very important technology in the event of a fire. It can remove high-temperature smoke and reduce fire damage. However, automatic opening has many detailed technical features, and it needs to be carefully planned and designed in consideration of various possibilities. For example, the function of the air valve Whether the airflow guided by the window is enough to push the window when it is opened, if the airflow cannot be pushed due to the heavy weight of the window, the entire automatic system will have no function even if there is no fault, and whether the opened window will be caused by the heavy weight and the cylinder cannot support it. windows closed again

In addition, most of the traditional technologies use electric methods to control the opening and closing of windows instead of pneumatic ones. However, electric methods tend to fail in the event of a fire, resulting in the windows not being able to be opened. Even if they can be opened, the opening speed of electric methods is not fast enough to Comply with legal requirements and affect smoke exhaust
