[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0024] refer to Figure 1-10 , a folded structure integrated air circuit board, including a first integrated air circuit board 1, a second integrated air circuit board 2 and a connecting shaft 3, and the first integrated air circuit board 1 and the second integrated air circuit board 2 are connected through the connecting shaft 3 Rotation connection, the first integrated air circuit board 1 is connected and sealed by the first upper cover 4 and the first bottom plate 5 by brushing glue, and the second integrated air circuit board 2 is connected by the second upper cover 6 and the second bottom plate 7 by brushing glue Sealing, forming a waterproof sealing layer, enhancing the waterproofness of the first integrated air circuit board 1 and the second integrated air circuit board 2, the first bottom plate 5 and the second bottom plate 7 are equipped with air channel grooves 8, and the connecting shaft 3 The interior is provided with an air channel 9 along the axial direction, and the surface of the connecting shaft 3 is uniformly provided with an air channel notch 10 along the axial direction, and the air channel notch 10 is provided with an air hole 11 communicating with the air channel. Corresponding to the air outlet position of the air channel groove 8, the first integrated air circuit board 1 and the second integrated air circuit board 2 can be folded into different angles under the action of the connecting shaft 3, so that the overall external dimensions It has been adapted to different air circuit templates and installation environments. One side of the first upper cover 4 is provided with an upper installation hole 15, and one side of the upper installation hole 15 is provided with a pneumatic component connecting pipe hole 14. The first bottom plate 5 The upper left end is provided with lower installation hole 16, and one end of air passage 9 is equipped with air passage plug 13, and the surface of air passage notch 10 is provided with sealing ring notch 12, the first loam cake 4, the first base plate 5, the second The upper cover 6 and the second bottom plate 7 are all anti-rust aluminum alloy structures, which enhance the anti-rust and anti-corrosion performance of the present invention. The first integrated air circuit board 1 is in a "concave" shape; the second integrated air circuit board 2 is in a "convex" shape , and coincides with the first integrated air circuit board 1, so that the first integrated air circuit board 1 and the second integrated air circuit board 2 can form a smaller angle when they can be rotated and connected through the connecting shaft 3, so as to adapt to the small space In the installation environment, the surfaces of the first upper cover 4 and the second upper cover 6 are provided with a pneumatic element connecting pipe hole 14 and an upper mounting hole 15; the pneumatic element connecting pipe hole is connected with the air channel groove 8; Located at the top corners of the first upper cover 4 and the second upper cover 6, the first bottom plate 5 and the second bottom plate 7 are provided with lower mounting holes 16 at positions corresponding to the upper mounting holes 15; the first upper cover 4 The first bottom plate 5 and the second upper cover 6 and the second bottom plate 7 are connected by bolts that are matched with the upper installation hole 15 and the lower installation hole 16 at the same time. An annular sealing ring notch 12 is also provided, and the width of the air channel notch 10 is larger than the diameter of the air outlet hole of the air channel groove 8 .

[0025] The invention realizes the folding of the integrated air circuit board, changes the volume of the integrated air circuit board, reduces the installation space, and adapts to the air circuit templates of various rail vehicles; Lightweight, high structural strength and reliability, and excellent anti-corrosion and anti-rust performance.

[0026] The concrete steps of brushing glue of the present invention are:

[0027] (1) The bottom surface of the first upper cover 4 and the second upper cover 6 and the top surface of the first bottom plate 5 and the second bottom plate 7 are used as bonding surfaces for sandblasting, then polished and smoothed, rinsed, and air-dried 15-30min;

[0028] (2) Turn on the oven and raise the temperature of the oven to 55-65°C; place the first upper cover 4, the second upper cover 6, the first bottom plate 5 and the second bottom plate 7 with the adhesive faces upward together with the adhesive Put it in the oven and keep warm for 25-35min;

[0029] (3) Use a silk screen to evenly brush glue on the top surfaces of the first bottom plate 5 and the second bottom plate 7, and check the quality of the glue brushing;

[0030] (4) Put the adhesive surfaces of the first upper cover 4 and the second upper cover 6 facing down, align with the first bottom plate 5 and the second bottom plate 7 respectively and bond them to form the first integrated air circuit board 1 and the second integrated air circuit board 1 . 2. Integrated gas circuit board 2, and put it into the heating furnace; raise the temperature in the heating furnace to 110-125°C at a rate of 35-45°C/h, keep it warm for 2.5-3.5h, then cool with the furnace, and wait for heating When the temperature in the furnace is lower than 35°C, open the furnace door and take it out;

[0031] (5) Evenly apply waterproofing agent on the sides of the first integrated air circuit board 1 and the second integrated air circuit board 2 to form a waterproof sealing layer.

[0032] The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, any person familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solution of the present invention Any equivalent replacement or change of the inventive concepts thereof shall fall within the protection scope of the present invention.
