[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0023] A corrugated HVAC pipe assembly, as Figures 1-4 shown, includes a bellows 1. Connecting pipes 2 are inserted and installed at both ends of the bellows 1. Sliding seats 9 are slidably connected to the side walls at both ends of the bellows 1. A sleeve one 13 and a sleeve two 15 are fixedly connected to the two groups of sliding seats 9 respectively. The sleeve one 13 and the sleeve two 15 are inserted and connected to each other, and are fixedly connected by screws between the sleeve one 13 and the sleeve two 15. Locking components for adjusting the positions of the sliding seats 9 are fixedly connected to the side walls at both ends of the bellows 1. The end parts of the two groups of locking components are rotatably connected to the two groups of sliding seats 9 respectively.

[0024] Install the two ends of the bellows 1 to the two groups of connecting pipes 2 respectively. Control the sliding of the sliding seat 9 through the locking component, adjust the insertion length between the sleeve one 13 and the sleeve two 15, and then screw on the screws to fix, so as to adjust and fix the length of the corrugated part of the bellows 1, which is convenient for connecting different distances between the two groups of connecting pipes 2. The sleeve one 13 and the sleeve two 15 can be bent, which is convenient for bending the corrugated part of the bellows 1 and protecting the outer wall of the bellows 1.

[0025] As Figures 1-3 shown, the locking component includes a fixed ring 12. The fixed ring 12 is fixedly connected to the side wall of the connecting pipe 2. A plurality of screws 11 are threadedly connected to the fixed ring 12. The plurality of screws 11 are arranged in a circumferential array. A plurality of grooves 10 are opened on one side of the two groups of sliding seats 9. The shape of the grooves 10 is set as a "convex" shape. The plurality of grooves 10 are arranged in a circumferential array. One ends of the plurality of screws 11 are respectively rotatably installed in the plurality of grooves 10.

[0026] The fixing ring 12 is sleeved and fixed to the side walls at both ends of the corrugated pipe 1. One end of the screw 11 is rotatably connected to the groove 10 of the sliding seat 9. When the screw 11 is rotated, one end of the screw 11 rotates with the sliding seat 9, and the length of the screw 11 between the fixing ring 12 and the sliding seat 9 changes, pushing or pulling the sliding seat 9, thereby changing the position of the sliding seat 9 on the corrugated pipe 1. After the corrugated pipe 1 and the connecting pipe 2 are installed, the first sleeve 13 and the second sleeve 15 are inserted first, and then the position of the sliding seat 9 is adjusted so that the corrugated part shrinks or extends to a suitable length. Then the screw is tightened so that the insertion distance between the first sleeve 13 and the second sleeve 15 is fixed, and the length of the corrugated pipe 1 is adjusted and fixed.

[0027] like Figure 2 As shown, the first sleeve 13 has an insertion port 14 at one end, and one end of the second sleeve 15 is inserted into the insertion port 14. An insulation pad 16 is adhered to the inner wall of the first sleeve 13, and one end of the insulation pad 16 is inserted into the second sleeve 15.

[0028] One end of sleeve 2 15 is inserted into the socket 14 of sleeve 1 13. By adjusting the insertion length between the two, the length of the corrugated pipe 1 can be controlled.

[0029] like Figures 1-4 As shown, one end of the connecting pipe 2 has a connecting port 3, and the end of the corrugated pipe 1 is inserted into the connecting port 3. One end of the connecting pipe 2 is engaged with the side wall of the corrugated pipe 1. A sealing gasket 4 is engaged inside the connecting pipe 2 and is pressed between the connecting pipe 2 and the corrugated pipe 1.

[0030] The end of the corrugated pipe 1 is inserted into the connection port 3 of the connecting pipe 2. The sealing gasket 4 ensures the sealing of the connection between the two. Then, the end of the connecting pipe 2 is snapped into the corrugated pipe 1, so that the connecting pipe 2 and the corrugated pipe 1 are fixedly installed, and the connecting pipe 2 and the corrugated pipe 1 are connected.

[0031] like Figures 1-4 As shown, one end of the connecting pipe 2 is fixed with multiple sets of connecting plates 6, and the side wall of the end of the corrugated pipe 1 is provided with multiple sets of slots 5. The number of connecting plates 6 and slots 5 is the same. The multiple sets of connecting plates 6 and slots 5 are arranged in a circumferential array. Each set of connecting plates 6 is fixed with a locking block 7, and the multiple sets of locking blocks 7 are respectively engaged with the multiple sets of slots 5.

[0032] After the corrugated pipe 1 and the connecting pipe 2 are inserted, the locking blocks 7 on the multiple sets of connecting plates 6 respectively engage with the multiple sets of locking slots 5, so that the connecting pipe 2 and the corrugated pipe 1 will not separate. The locking blocks 7 and the connecting plates 6 are used as a structure to replace the bolt installation, reducing the number of independent parts and making the installation more convenient.

[0033] like Figures 1-4 As shown, both ends of the corrugated pipe 1 are fitted with retaining rings 8, and the ends of the multiple sets of connecting plates 6 are all set in an inclined state, with the retaining rings 8 fitted on the multiple sets of connecting plates 6.

[0034] After the locking block 7 engages with the locking slot 5, the sliding retaining ring 8 slides along the inclined surface at the end of the connecting plate 6 onto the connecting plate 6, holding multiple sets of connecting plates 6 in place, so that the locking block 7 will not detach from the locking slot 5.

[0035] The working principle of the corrugated HVAC pipe assembly provided by this utility model is as follows:

[0036] Install the two ends of the corrugated pipe 1 to the two sets of connecting pipes 2 respectively. Control the sliding seat 9 to slide through the locking component, adjust the insertion length between sleeve 13 and sleeve 2 15, and then tighten the screws to fix it, thereby adjusting and fixing the length of the corrugated part of the corrugated pipe 1, which is convenient for connecting the two sets of connecting pipes 2 at different distances. Sleeve 13 and sleeve 2 15 can be bent, which is convenient for bending the corrugated part of the corrugated pipe 1 and protects the outer wall of the corrugated pipe 1.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
