Description

Technical Field

[0001] The utility model relates to the field of underground air windows, in particular to a mechanical pin-locking type air window positioning mechanism. Background Art

[0002] As a tool for the air inlet, the underground air window in coal mines can increase the number of air inlets of the ventilation system, improve the air circulation condition, reduce the concentration of harmful gases such as carbon dioxide and gas, and ensure the life safety and health of miners.

[0003] The adjustable air window in the prior art is composed of an air window frame and an air window plate. The air window plate is slidably arranged in the air window frame, and the air volume is controlled by controlling the size of the gap left by the air window plate in the air window frame. After adjusting the air volume, in order to prevent the displacement of the air window positioning plate caused by blasting vibration and other situations, the most common method in the prior art is to fix the air window plate with iron nails, that is, to pass the iron nails through the air window plate and then nail them into the air window positioning plate at the back. This fixing method has many disadvantages. One is that it is inconvenient to adjust, that is, when adjusting, it is necessary to first remove the nails and then nail them again; the other is that the service life of the equipment is affected. Frequently nailing and removing nails cause great damage to the service life of the air window positioning plate and the air window plate. In the prior art, such as a mine-used precisely adjustable automatic air window disclosed in Chinese Patent CN201921020705.4, although the equipment can accurately adjust the opening degree of the air window, its implementation conditions require high, and specific equipment such as cylinders and solenoid valves need to be configured. Also, due to the complex underground environment, which is humid and contains poisonous and flammable gases, its service life is worrying, the assembly and maintenance are complex, and electrical equipment requires special explosion-proof equipment, and the configuration cost is high. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a mechanical pin-locking type air window positioning mechanism with a simple structure, which can more accurately control the opening degree of the air door, especially with low layout cost and fast adjustment.

[0005] The device includes an air window frame, and an air window plate is slidably arranged in the air window frame;

[0006] An air window positioning plate is fixedly arranged behind the air window frame and the air window plate;

[0007] A positioning connecting rod is hinged on the air window plate. One end of the positioning connecting rod is hinged on the air window plate, and the other end is provided with a pin-locking part;

[0008] A plurality of air window positioning holes are formed on the air window positioning plate.

[0009] That is to say, by inserting the pin-locking part into the air window positioning hole, the fixing of the air window plate in the air window frame can be realized, that is, a certain area of air flow channel is left.

[0010] The beneficial effects of the present utility model are as follows: The present utility model can improve the service life of the wind window plate and the wind window positioning plate, with low layout cost and rapid adjustment. In particular, the densely arranged wind window positioning holes can precisely adjust the area of the air flow channel. Its implementation requirements are low, without the participation of electrical equipment, and it has a wide range of application and safety promotion value. Description of the Drawings
