DETAILED DESCRIPTION

[0023] EMBODIMENT

[0024] REFERENCE Figures 1 to 4 The combined ventilation pipe of the embodiment comprises an assembled pipe 1, clamping mechanisms 2 are fixedly installed at the two ends of one side of the assembled pipe 1, side pipes 4 are installed on the two sides of the assembled pipe 1 through the clamping mechanisms 2, the inner ends of the side pipes 4 are inserted into the two sides of the assembled pipe 1, a linkage mechanism 3 is fixedly installed at the middle of one side of the assembled pipe 1 close to the clamping mechanism 2, and the linkage mechanism 3 and the clamping mechanism 2 are linked with each other.

[0025] The clamping mechanism 2 comprises a limiting groove 21 and a vertical rail 22. The limiting groove 21 is arranged at the top and bottom of the inner end of the side duct 4, and also arranged at the top and bottom of the two sides of the assembled pipe 1. The vertical rail 22 is fixedly installed at the two ends of one side of the assembled pipe 1. The inner part of the vertical rail 22 is provided with an elastic assembly 23. The outer end of the elastic assembly 23 is inserted into the limiting groove 21 of the inner end of the side duct. The assembled pipe 1 and the side duct 4 on both sides are connected by the clamping mechanism 2, so that the installation of the ventilation duct is more flexible and convenient. The limiting groove 21 and the vertical rail 22 of the clamping mechanism 2 are designed ingeniously. When the inner end of the side duct 4 is inserted into the two sides of the assembled pipe 1, the elastic assembly 23 in the inner part of the vertical rail 22 cooperates with the limiting groove 21 to achieve quick and stable clamping installation. This connection method does not require complex tools and tedious operation during installation, greatly improving the installation efficiency. At the same time, the linkage mechanism 3 arranged at the middle of one side of the assembled pipe 1 near the clamping mechanism 2 is interconnected with the clamping mechanism 2, which further enhances the convenience of the ventilation duct during disassembly and assembly, so that the side duct 4 can be quickly disassembled from the assembled pipe 1 when maintenance or adjustment is required, improving the maintainability of the entire ventilation system. This combined ventilation duct provides an efficient and convenient solution for the installation and maintenance of the ventilation system.

[0026] Reference Figures 1-3 The elastic assembly 23 comprises a telescopic spring 231 fixedly installed at the inner two ends of the vertical rail 22. The outer end of the telescopic spring 231 is fixedly connected with a limiting piece 232. The inner side and outer end of the limiting piece 232 are fixedly connected with a clamping block 233. The end of the clamping block 233 penetrates through the limiting groove 21 of the spliced pipe and is inserted into the limiting groove 21 of the side duct. The outer side and lower end of the clamping block 233 is provided with an inclined surface. The overall cross-sectional shape of the clamping block 233 is arranged in a right triangle. The telescopic spring 231 of the elastic assembly 23 is fixedly installed at the inner two ends of the vertical rail 22, providing stable elastic support for the entire assembly. When the side duct 4 is inserted into the assembled pipe 1, the side duct 4 contacts the inclined surface at the outer side and lower end of the clamping block 233. Due to the design of the inclined surface, the clamping block 233 is extruded, the limiting piece 232 can resist the telescopic spring 231 and make it stretch, so that the side duct 4 can be smoothly inserted. When the assembled pipe 1 is inserted into the side duct 4, the telescopic spring 231 drives the limiting piece 232 to move inward by virtue of its reset feature, and then drives the clamping block 233 to be inserted into the limiting groove 21 of the side duct 4. The overall cross-sectional shape of the clamping block 233 is arranged in a right triangle. This shape not only guides the side duct 4 better during insertion, but also provides stable connection after clamping, ensuring that the side duct 4 is firmly clamped and installed at the two ends of the assembled pipe 1. The design of the elastic assembly 23 makes the installation of the ventilation duct more convenient, quick and stable.

[0027] Reference Figure 4The linkage mechanism 3 comprises a sliding groove 31 and a guide frame 32. The sliding groove 31 is arranged in the middle of one side of the assembled pipe 1 close to the vertical rail 22. The inside of the sliding groove 31 is slidably connected with a sliding plate 33. The outer side of the sliding plate 33 is fixedly connected with a linkage plate 34. The guide frame 32 is fixedly installed at the inner end of the limiting piece 232. The two sides of the linkage plate 34 are abuttingly connected with the inner side of the guide frame 32. The inner end of the guide frame 32 is also provided with an inclined surface. The two ends of the linkage plate 34 are provided with inclined surfaces at the top and bottom. The two ends of the linkage plate 34 are in the shape of an isosceles triangle as a whole. The front surface of the linkage plate 34 is fixedly installed with a bridge handrail 35. The outer surface of the bridge handrail 35 is fixedly connected with an anti-skid handrail cover. The inner end of the side pipe 4 is fixedly connected with an anti-skid washer 5. The inner side of the anti-skid washer 5 is abuttingly connected with the two sides of the assembled pipe 1. The sliding groove 31 provides a stable sliding track for the sliding plate 33, ensuring that the sliding plate 33 can smoothly move on the assembled pipe 1. The linkage plate 34 on the outer side of the sliding plate 33 cooperates with the guide frame 32. When disassembly is needed, the linkage plate 34 is pushed by holding the bridge handrail 35. The inclined surfaces at the two ends of the linkage plate 34 are abuttingly connected with the inclined surface at the inner end of the guide frame 32, which can efficiently transmit the force and push the guide frame 32 to move outward, thereby driving the limiting piece 232 to move outward, so that the clamping block 233 is separated from the limiting groove 21, realizing the quick disassembly of the side pipe 4 and the assembled pipe 1. The two ends of the linkage plate 34 are in the shape of an isosceles triangle as a whole, making the action of the inclined surface more stable and uniform. The anti-skid handrail cover on the outer surface of the bridge handrail 35 increases the friction of the operation, facilitating the pushing operation of the user. At the same time, the anti-skid washer 5 on the outer surface of the inner end of the side pipe 4 not only increases the sealing property of the connection between the side pipe 4 and the assembled pipe 1, but also prevents the sliding of the connection part, improving the stability and reliability of the whole ventilation pipe.

[0028] Principle and advantages: By setting the elastic mechanism, when installation is needed, the side pipe 4 can be inserted into the two ends of the assembled pipe 1. In this process, the side pipe 4 will contact the inclined surface of the clamping block 233. Because the inclined surface of the clamping block 233 is extruded, the limiting piece 232 will resist the extension spring 231 and drive it to stretch. In this way, the side pipe 4 can be stably inserted into the two ends of the assembled pipe 1. After the assembled pipe 1 is inserted into the two ends of the side pipe 4, the extension spring 231 will drive the limiting piece 232 to move inward due to its reset feature. The inward movement of the limiting piece 232 will drive the clamping block 233 to move inward and be inserted into the limiting groove 21. Through the mutual clamping of the clamping block 233 and the limiting groove 21, the side pipe 4 can be firmly clamped and installed at the two ends of the assembled pipe 1. During use, according to specific needs, multiple assembled pipes and side pipes 4 can be flexibly selected for auxiliary butt joint installation. This design facilitates the quick combination and installation of the device, greatly improving the convenience of the whole device.

[0029] By setting the linkage mechanism 3, so that the device during disassembly operation, can be through the hand bridge handrails 35, to the required disassembly side of the side pipe 4 push linkage plate 34, at this time, the slide plate 33 will slide smoothly in the inner side of the chute 31, the slope of the linkage plate 34 will extrude the inner end slope of the guide frame 32, in this way, the linkage plate 34 can push the guide frame 32 to move outward, the guide frame 32 moves outward, will rely on its slope to touch and push the limiting piece 232 outward, the limiting piece 232 moves outward will drive the clamping block 233 from the inside of the limiting groove 21, once the clamping block 233 from the side pipe 4 on the inside of the limiting groove 21, the side pipe 4 can be taken out from the inside of the assembled pipe 1, this makes the device during the whole use can realize quick disassembly and repair, improve the convenience of the whole use of the device, it can be seen, the device needs to be disassembled, just need to simply adjust the push slide plate 33 and linkage plate 34 displacement to one side, can open the limiting piece 232, so as to facilitate the quick disassembly of the side pipe 4 and the assembled pipe 1, this design can further improve the convenience of the whole use of the device.
