[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] See Figures 1-4 A pneumatic air valve for a car windshield pressing device comprises: an outer frame 1, which is closed on all four sides and open at the top; a partition mechanism 2 located at the bottom of the outer frame 1, capable of opening or closing the bottom of the outer frame 1; and a drive mechanism 3 located on the outer frame 1, capable of driving the partition mechanism 2 to open or close the bottom of the outer frame 1. The valve is actuated by a cylinder 33. Multiple layers of pressure plates 23 are installed inside the valve, with rubber sealing gaskets mounted on the pressure plates 23. When the cylinder 33 is actuated, the pressure plates 23 are moved via a connecting rod, with each layer of pressure plates 23 overlapping each other, enabling rapid switching between sealing and blowing, ensuring a sealed space is formed between the vacuum cover and the glass during adsorption.
[0032] The bottom of the outer frame 1 is provided with a series of partition mechanisms 2. Each partition mechanism 2 has: a swing shaft 21, rotatably mounted on the outer frame 1; a mounting base 22, fixedly mounted on the swing shaft 21; a pressure plate 23, fixedly mounted on the mounting plate; and a sealing strip 24, mounted on the pressure plate 23. The sealing strips 24 of adjacent partition mechanisms 2 can seal each other. By rotating the swing shaft 21, the mounting base 22 and the pressure plate 23 are driven to rotate, thereby enabling the sealing strips 24 of adjacent partition mechanisms 2 to seal each other. This allows for a rapid switch between sealing and blowing, ensuring that a sealed space can be formed between the vacuum cover and the glass during adsorption.
[0033] The drive mechanism 3 includes: a swing arm 31, fixedly connected to the swing shaft 21; a connecting rod 32, through which the swing arms 31 of adjacent partition mechanisms 2 are hinged; and a cylinder 33, whose piston rod is hinged to the swing arm 31 of one partition mechanism 2. The cylinder 33 pulls the valve, which contains multiple layers of pressure plates 23. Rubber sealing gaskets are installed on the pressure plates 23. When the cylinder 33 pulls, the pressure plates 23 move via a connecting rod, with each layer of pressure plates 23 overlapping each other. This allows for rapid switching between sealing and blowing, ensuring a sealed space is formed between the vacuum cover and the glass during adsorption.
[0034] Mounting base 22 is fixedly connected to swing shaft 21 via tension sleeve 25. By adjusting tension sleeve 25, it can be fixed or loosened.
[0035] The swing shaft 21 is rotatably mounted on the outer frame 1 via the bearing 34, and the rotation process of the swing shaft 21 is stable and reliable.
[0036] The connecting rod 32 is a positive and negative screw. The swing arm 31 is connected to the pressure plate 23, which has a positional deviation, through the positive and negative screw. The deviation can be compensated by adjusting the screw.
[0037] With the above structure, the switching between sealing and blowing can be completed quickly, ensuring that a sealed space can be formed between the vacuum cover and the glass during adsorption.
