A second screw hole 21 is opened at the top of the fixing block 20, and the second screw hole 21 penetrates the fixing block 20 and the inner bottom end of the first mounting sleeve 1. The inner side of the second screw hole 21 is threadedly connected with a second bolt 22, and the bottom end of the second bolt 22 is threadedly connected to the inside of the first mounting sleeve 1 through the second screw hole 21. Due to the existence of the filter plate 18, the filter plate 18 can effectively filter the wind entering the first ventilation pipe 3 and the second ventilation pipe 4, thereby reducing the particulate matter circulating in the ventilation pipe. When the filter plate 18 needs to be disassembled for maintenance or cleaning, the second bolt 22 is screwed out of the second screw hole 21, and then it can be directly pulled out through the slide slot 2.

[0029] refer to Figure 4 and Figure 5 A card slot 14 is provided on one side of the first ventilation pipe 3, and a card block 12 matching the card slot 14 is fixedly connected to the other side of the second ventilation pipe 4. The card block 12 is carded into the inside of the card slot 14, and the second ventilation pipe 4 is carded to one side of the first ventilation pipe 3 through the card slot 14 and the card block 12. Because the second ventilation pipe 4 is carded to one side of the first ventilation pipe 3, when the second ventilation pipe 4 needs to be disassembled individually at a later time, the card block 12 can be directly pulled out of the card slot 14, which is also convenient for the user to perform individual maintenance on the first ventilation pipe 3 or the second ventilation pipe 4 at a later time.

While improving the overall sealing performance of the device, it can also effectively avoid air leakage at the connection point between the first ventilation pipe 3 and the second ventilation pipe 4.

[0031] Principle and advantages of use: When in use, first fix the positions of the first mounting sleeve 1 and the second mounting sleeve 5, which can effectively protect and support the two sides of the first ventilation pipe 3 and the second ventilation pipe 4. When installing the first ventilation pipe 3 and the second ventilation pipe 4, directly slide them into the inner side of the first mounting sleeve 1 and the second mounting sleeve 5 through the slide groove 2 and the first slider 6. To prevent the first ventilation pipe 3 and the second ventilation pipe 4 from displacement, tighten the first bolt 10 to support the position of the first ventilation pipe 3 and the second ventilation pipe 4, thereby preventing their positions from displacement and facilitating use. The operator can adjust the installation length of the first ventilation pipe 3 and the second ventilation pipe 4 according to the needs. When disassembling the two later, the first bolt 10 is screwed out, and then it can be directly pulled out of the first installation sleeve 1, which can facilitate the disassembly and assembly of the first ventilation pipe 3 and the second ventilation pipe 4, and can also effectively improve the maintenance efficiency of the first ventilation pipe 3 and the second ventilation pipe 4 in the later stage. Due to the presence of the rubber pad 8, the rubber product has good anti-slip ability and rubber shock absorption ability, which can improve the stability of the first bolt 10 position screwing in, and can also prevent the first ventilation pipe 3 or the second ventilation pipe 4 from being bumped. With the opening 15, the user can directly check the inside of the first ventilation duct 3 or the second ventilation duct 4 through the transparent glass 16 without disassembling the first ventilation duct 3 or the second ventilation duct 4, which is conducive to the user to observe the operating conditions of the inside of the first ventilation duct 3 or the second ventilation duct 4 at a later time, and can effectively improve the safety protection of the metro electromechanical installation. Due to the existence of the filter plate 18, the filter plate 18 can effectively filter the wind entering the first ventilation duct 3 and the second ventilation duct 4, thereby reducing the particulate matter circulating in the ventilation duct. When it is necessary to disassemble the filter plate 18, When it is maintained or cleaned, the second bolt 22 is screwed out of the second screw hole 21, and then it can be directly pulled out through the slide groove 2. Because the second ventilation pipe 4 is clamped on one side of the first ventilation pipe 3, when the second ventilation pipe 4 needs to be removed individually at a later time, the clamping block 12 can be directly pulled out of the clamping groove 14. It is also convenient for the user to perform individual maintenance on the first ventilation pipe 3 or the second ventilation pipe 4 at a later time. Due to the presence of the sealing ring 11, the sealing ring 11 can effectively seal the connection point of the first ventilation pipe 3 and the second ventilation pipe 4, thereby effectively improving the overall sealing of the device.
