DETAILED DESCRIPTION

[0020] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a ventilation device for subway stations that is easy to install, including a ventilation device body 1, a sliding frame 2 is provided outside the ventilation device body 1, and sliding seats 3 are fixedly connected to the two sides of the top and the bottom of the sliding frame 2, respectively, and a mounting base 4 is provided outside the sliding frame 2. A plurality of slideways 9 are provided inside the mounting base 4. The slideways 9 and the sliding seats 3 are both T-shaped in design. The slideways 9 can limit the sliding seats 3. The sliding seats 3 will not separate from the slideways 9 during the movement of the sliding frame 2, thereby improving the stability of the sliding frame 2 driving the ventilation device body 1 to move;

[0022] A pipe discharge hole 11 is provided on the back of the sliding frame 2, and heat discharge holes 12 are respectively provided on the top and bottom of the sliding frame 2. The pipe discharge holes 11 facilitate the connection of the built-in pipes in the wall with the ventilation device body 1. The heat discharge holes 12 can dissipate the heat generated by the ventilation device body 1, thereby preventing the heat from accumulating in the sliding frame 2 and affecting the normal use of the ventilation device body 1.

[0023] Side stop plates 13 are respectively connected to both sides of the ventilation equipment body 1, and the side stop plates 13 are fixed in the sliding frame 2. Because of the side stop plates 13, the ventilation equipment body 1 is installed inside the sliding frame 2, and the two side stop plates 13 are used to support the ventilation equipment body 1, thereby improving the placement stability of the ventilation equipment body 1.

[0024] Three mounting holes 10 are respectively provided on both sides of the front side of the mounting base 4, and the sliding frame 2 is slidably connected in the mounting base 4;

[0025] A cavity 5 is provided in the slide seat 3, and a positioning assembly 6 is provided in the cavity 5. One end of the positioning assembly 6 is embedded in the mounting base 4. The positioning assembly 6 includes a connecting plate 601, and a clamping plate 602 is fixed to one side of the connecting plate 601.

[0026] A card slot 8 is formed on the inner wall of the slideway 9, and the card plate 602 is carded in the card slot 8. The portion of the card plate 602 embedded in the card slot 8 is designed to be arc-shaped, so that when the slide frame 2 slides toward the inside of the mounting base 4, the card plate 602 can be squeezed to slide into the cavity 5, and will not hinder the sliding of the slide seat 3 in the slideway 9;

[0027] A sliding hole 7 is provided on the front side of the slide seat 3, and the extension plate 605 is slidably connected in the sliding hole 7. The sliding hole 7 serves to limit the extension plate 605, thereby ensuring that the extension plate 605 can slide freely within a certain stroke.

[0028] Two telescopic rods 603 are fixed on the other side of the connecting plate 601, and the ends of the two telescopic rods 603 are fixed on the inner wall of the cavity 5. A spring 604 is connected to the outer sleeve of the telescopic rod 603, and the spring 604 is fixed between the cavity 5 and the connecting plate 601. An extension plate 605 is fixed on the front of the connecting plate 601, and a handle 606 is connected to the extension plate 605. Through the mutual cooperation between the spring 604 and the connecting plate 601, the connecting plate 601 is supported by the elastic force of the spring 604, so that the connecting plate 601 can drive the card plate 602 to automatically snap into the card slot 8, without the need for human assistance, thereby improving the convenience of operation.

[0029] The working principle of the utility model is:

[0030] When installing the ventilation equipment main body 1, the sliding frame 2 is pushed by multiple handles 606, so that the sliding frame 2 drives the ventilation equipment main body 1 to slide inside the installation base 4 until the ventilation equipment main body 1 and the wall are completely located inside the wall. The connecting plate 601 is supported by the elastic force of multiple springs 604, so that the telescopic rod 603 drives the card plate 602 to be inserted into the card slot 8 through the connecting plate 601, thereby achieving the purpose of limiting the sliding seat 3 and the installation base 4. When removing the ventilation equipment main body 1, the two sets of handles 606 are squeezed, so that the two relative handles 606 drive the connecting plate 601 to move through the extension plate 605, so that the two connecting plates 601 drive the two card plates 602 to approach each other until the card plates 602 are separated from the card slot 8, and the sliding frame 2 is pulled by the handle 606 to slide in the installation base 4, and the sliding frame 2 drives the ventilation equipment main body 1 to extend out of the wall and it can be removed.
