It is used to transfer air from the air conditioning equipment to a room or other areas, and to send the recirculated air back to the air conditioning equipment. It is a main part of the air conditioning system. Especially inside a large building, ventilation pipes are needed to transport the air flow to a designated location.

[0003] When connecting existing ventilation pipes, they are generally docked in the form of bolts or flange pipes. Although the docking function can be achieved, since the ventilation pipes are often at a relatively high position, using the connection method of flange pipes or bolts requires lifting and aligning the pipes and tightening the bolts one by one for fixation. This method is time-consuming and laborious, and during the docking process, other accessories such as bolts and gaskets are prone to falling. It is impossible to achieve quick docking and assembly, reducing its installation convenience. Summary of the Utility Model

[0020] In order to make the purpose and advantages of the present utility model more clear, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0021] As Figures 1 - 4As shown in the figure, a quick-connect air-conditioning ventilation pipe structure includes a pipe 1 and a docking pipe 2. The docking pipe 2 is located between the pipes 1. The outer diameter of the docking pipe 2 is smaller than the inner diameter of the pipe 1. The cross-section of the docking pipe 2 is in a T-shaped structure. The docking pipe 2 is hollow. A number of positioning rods 3 are movably connected to the side wall of the docking pipe 2. Positioning holes 4 corresponding to the positioning rods 3 are provided on the inner wall of the pipe 1, and both the positioning rods 3 and the positioning holes 4 are distributed in a circular array. A first transmission member and a second transmission member are provided in the inner cavity of the docking pipe 2.

[0022] Among them, the cross-sectional shape of the positioning hole 4 can be any one of a rectangle, a circle, and an annulus. In actual use, users can produce and select according to their needs, and the specific structural shape is not limited in this solution.

[0023] As Figure 4 shown in the figure, the first transmission member includes a rotating rod 8 rotatably connected to the side wall of the docking pipe 2. One end of the rotating rod 8 is fixedly connected with a first bevel gear 7. A ring plate 6 is rotatably connected to the side wall of the inner cavity of the docking pipe 2. Two rows of tooth blocks 9 are fixedly connected to the side wall of the ring plate 6. A second bevel gear 10 is arranged below the first bevel gear 7. Both the first bevel gear 7 and the second bevel gear 10 are engaged with the tooth blocks 9.

[0024] Specifically, the engagement mode of the first bevel gear 7 and the second bevel gear 10 with the tooth blocks 9 belongs to a mechanical structure that is easy to think of by those skilled in the art. When driving the first bevel gear 7 to rotate, the ring plate 6 can be driven to rotate through the tooth blocks 9. The ring plate 6 synchronously drives other second bevel gears 10 to rotate through the tooth blocks 9, so that the positioning rods 3 can achieve the purpose of synchronous extension, which can not only play a fixing role but also play a positioning effect.

[0025] As Figure 3 shown in the figure, a screw rod 11 is fixedly connected to the bottom surface of the second bevel gear 10. A limiting plate 12 is fixedly connected to the side wall of the inner cavity of the docking pipe 2. The screw rod 11 passes through the limiting plate 12 and is rotatably connected to the docking pipe 2. The screw rod 11 is rotatably connected to the limiting plate 12. A screw sleeve 16 is threadedly connected to the side wall of the screw rod 11. A support plate 5 is fixedly connected to the side wall of the screw sleeve 16. The positioning rods 3 are all fixedly connected to the support plate 5.

[0026] Among them, using the screw rod 11 as the driving structure, its structure is simple and its performance is stable. When the positioning rod 3 is tightened in the positioning hole 4, it is not easy to loosen.

[0027] As Figure 3 shown in the figure, a vertical rod 13 is fixedly connected to the end face of the screw sleeve 16. The top end of the vertical rod 13 passes through the limiting plate 12, and the vertical rod 13 is movably connected to the limiting plate 12. By providing the vertical rod 13, the screw sleeve 16 is limited to prevent the screw sleeve 16 from driving the positioning rod 3 to be misaligned when moving, thereby improving its stability.

[0028] A sealing ring 14 is fixedly connected to the side wall of the docking pipe 2, and a sealing groove 15 is formed on the end face of the pipe 1. The sealing ring 14 is adapted to the sealing groove 15. By providing the sealing ring 14 and the sealing groove 15, after the two pipes 1 are docked with the docking pipe 2, the sealing ring 14 is simultaneously clamped into the sealing groove 15, achieving the effect of efficient sealing.

[0029] The working principle of this utility model is as follows: When it is necessary to dock the pipe 1, first insert both ends of the docking pipe 2 into the inside of the pipe 1. After aligning the positioning rod 3 with the positioning hole 4, then rotate the rotating rod 8 to drive the first bevel gear 7 to rotate. The first bevel gear 7 meshes with the tooth block 9 to drive the annular plate 6 to rotate. The annular plate 6 meshes with the second bevel gear 10 through the tooth block 9 and drives the screw rod 11 to rotate. The screw rod 11 drives the support plate 5 to move outward through the screw sleeve 16, and the support plate 5 drives the positioning rod 3 to insert into the positioning hole 4, achieving the effect of rapid docking. The docking process can be completed without the aid of other tools and accessories, and it also has good sealing performance in cooperation with the sealing ring 14 and the sealing groove 15.

[0030] The above description is only a preferred embodiment of this utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
