DETAILED DESCRIPTION
[0019] The technical scheme of the utility model will be described below in conjunction with the drawings, obviously, the described embodiment is a part of the embodiment of the utility model, not all embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of the utility model protection.
[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] like Figures 1-4 This utility model discloses a ventilation duct for easy splicing, comprising a first duct 1 and a second duct 2. Connecting plates 3 and 4 are respectively provided at both ends of the first duct 1 and the second duct 2. A sealing groove 18 is embedded in the first connecting plate 3, and a sealing gasket 19 is protruding from the second connecting plate 4. The sealing gasket 19 matches the sealing groove 18. When the first connecting plate 3 and the second connecting plate 4 are joined, the sealing gasket 19 is inserted into the sealing groove 18, achieving a sealing connection between the first duct 1 and the second duct 2 to prevent air leakage. A vertical plate 5 is fixedly connected to the outer wall of the first duct 1, and a vertical plate 6 is fixedly connected to the outer wall of the second duct 2. Locking devices 7 are provided on the first 5 and the second 6 to quickly splice the first duct 1 and the second duct 2. A tensioning drive device 8 is provided on the first vertical plate 5 to tension the locking device 7, thereby achieving a sealed connection between the first duct 1 and the second duct 2 to prevent air leakage.
[0022] like Figure 1 , 2 4. The locking device 7 includes a plug-in plate 9, which rotates on the second vertical plate 6 via a shaft and passes through the first vertical plate 5. A locking groove 10 is provided on the end face of the plug-in plate 9. A locking plate 11 is inserted into the first vertical plate 5 and can be inserted into the locking groove 10. An end plate 12 is fixedly connected to the outer end face of the locking plate 11. A spring 13 is sleeved on the locking plate 11. One end of the spring 13 is fixedly connected to the first vertical plate 5 and the other end is fixedly connected to the end plate 12. The spring 13 is held in place. A force is applied to the locking plate 11 in the direction of the locking groove 10. The end of the locking plate 11 is wedge-shaped. The locking groove 10 is adapted to the end of the locking plate 11. The plug plate 9 is inserted into the vertical plate 5. The locking plate 11 is inserted into the locking groove 10 under the action of the spring 13, thereby locking the plug plate 9. This achieves the function of splicing and fixing the air duct 1 and the air duct 2. The air duct 1 and the air duct 2 can be quickly spliced and the installation is very convenient.
[0023] like Figures 1-3The tensioning drive device 8 includes a horizontal plate 15, which is fixedly connected in pairs to the vertical plate 5. A gear 16 is rotatably connected between the horizontal plates 15 via a shaft. A wheel 17 is fixedly connected to the shaft end of the gear 16. A rack 14 is provided on the opposite side of the locking groove 10 on the plug plate 9 and meshes with the gear 16. The rack 14 slides with the plug plate 9 and is detachably inserted into the vertical plate 5. By rotating the wheel 17, the gear 16 can mesh with the rack 14, driving the plug plate 9 to slide in the vertical plate 5, thereby achieving the splicing and sealing of the air duct 1 and the air duct 2.
[0024] When it is necessary to splice the ventilation ducts, first rotate the vertical plate 6 on the second duct to a horizontal position, insert the plug plate 9 into the vertical plate 5, push the second duct to insert the sealing gasket 19 into the sealing groove 18, so that the connecting plate 3 and the connecting plate 4 are connected.
[0025] Because the spring 13 maintains elasticity against the locking plate 11, the locking plate 11 automatically inserts into the locking groove 10. Turning the wheel 17 causes the gear 16 to rotate and mesh with the rack 14, which causes the plug plate 9 to pull the second air duct 2, making the splicing of the second air duct 2 and the first air duct 1 tighter. Locking devices 7 and tensioning drive devices 8 are set on the upper and lower sides or around the first air duct 1 and the second air duct 2, which can quickly complete the splicing and sealing of the first air duct 1 and the second air duct 2, greatly improving the splicing efficiency and preventing air leakage.
[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
