[0036] 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 of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1:

[0038] As Figures 1 - 3 shown, this embodiment provides a heat-insulating HVAC pipe for an HVAC structure, which includes a support frame and a connection frame that are clamped to each other, and a thermal insulation layer is arranged in the frame formed by the support frame and the connection frame.

[0039] Among them, the support frame includes a first connecting plate 1 and support units 2 at both ends thereof. The overall contour of the support unit 2 is a cuboid structure, and a semi-circular groove 21 is arranged in the middle thereof. Card interfaces 22 with upward openings are respectively arranged at both ends of the support unit 2. A first arc-shaped support plate 3 is also clamped in the groove 21 of the support unit 2 for supporting the HVAC pipe.

[0040] The connection frame includes a second connecting plate 4 and connection units 5 at both ends thereof. The connection unit 5 is semi-circular, and clamping plates 51 are respectively arranged at both ends thereof for being clamped into the card interfaces 22 to realize the fixed connection between the connection unit 2 and the support unit 5. A second arc-shaped support plate 6 is clamped on the inner wall of the connection unit 5 for supporting the HVAC pipe.

[0041] Specifically, the arcs of the first arc-shaped support plate 3 and the second arc-shaped support plate 6 are the same and are respectively adapted to the outer diameter of the HVAC pipe 7. Therefore, the two first arc-shaped support plates 3 on the support frame and the two second arc-shaped support plates 6 on the connecting frame respectively abut against the outer wall of the HVAC pipe 7, playing a supporting role for the HVAC pipe 7. The first arc-shaped support plate 3 and the second arc-shaped support plate 6 are arranged on the inner walls of the support frame and the connecting frame, and each arc-shaped support plate is used to support the HVAC pipe. A heat insulation layer 8 is arranged in the space between the arc-shaped support plate and the support frame and the connecting frame, so that the heat insulation layer 8 has a suitable arrangement space, and the situation that the arrangement space at the bottom of the HVAC pipe is small or even non-existent due to the self-weight of the HVAC pipe below the HVAC pipe will not occur, thereby realizing the effective arrangement and fixation of the heat insulation layer 8.

[0042] More specifically, at least two first legs 31 are fixedly connected to the outer side of the first arc-shaped support plate 3. In this embodiment, two first legs 31 are arranged on the outer side wall of the first arc-shaped support plate 3. The first legs 31 are in a T-shaped shape, and first card slots 23 adapted to the first legs 31 are formed in the inner wall of the groove 21 of the support unit 2.

[0043] At least two second legs are fixedly connected to the outer side of the second arc-shaped support plate 6. In this embodiment, two second legs 61 are fixedly arranged on the outer side wall of the second arc-shaped support plate 6. The second legs 61 are in a T-shaped shape, and second card slots 52 adapted to the second legs 61 are formed in the inner wall of the connecting unit 5.

[0044] More specifically, one ends of the first card slot 23 and the second card slot 52 are respectively designed to be open. That is, the first card slot 23 is arranged on one side surface of the support unit 2, and the second card slot 52 is arranged on one side surface of the connecting unit 5, facilitating the first leg 31 or the second leg 61 to be inserted into the first card slot 23 or the second card slot 52, and also facilitating removal.

[0045] In this embodiment, the card interface 22 of the support unit 2 is a groove structure with an upward opening. The card connection plate 51 is inserted into the card interface 22, and the card connection plate 51 can be fixed to the end of the support unit 2 through the bolt 9.

[0046] The card connection plate 51 of the connecting unit 5 is in a straight plate shape and is adapted to the card interface 22. A first through hole 24 is formed in the outer wall of the card interface 22, and a second through hole 53 adapted to the first through hole 24 is formed in the card connection plate 51. By using the bolt 9 to pass through the first through hole 24 and the second through hole 53, the connecting unit 5 and the support unit 2 can be fixed, and further the connecting frame and the support frame can be fixed. Fixing each connecting unit 5 to the corresponding support unit 2 by using bolts can realize the fixed connection of the connecting frame and the support frame. This fixing method has a simple structure and is convenient to operate.

[0047] The heat-insulating HVAC pipe provided in this embodiment is fixed with the heat-insulating layer 8 arranged on the outer wall of the HVAC pipe 7 through a support frame and a connecting frame that are mutually clamped; the support frame and the connecting frame are fixedly connected through the clamping plate 51 being embedded into the mating clamping interface 22, thereby achieving the fixation of the outer heat-insulating layer 8 of the HVAC pipe 7. Since the width of the clamping plate 51 is smaller than the width of the clamping interface 22, after the clamping plate 51 is snapped into the clamping interface 22, moving the connecting member to the left or right can snap the clamping plate 51 into the clamping interface 22 of the support frame. In summary, the structural composition for fixing the heat-insulating layer outside the HVAC pipe is simple, the fixing method is easy to operate, and it is convenient for installation and disassembly.

[0048] Embodiment Two:

[0049] In this embodiment, as Figures 4 - 6 shown, the difference from Embodiment One is that a slotted opening 25 is also arranged on the side of the clamping interface 22, which is convenient for the clamping plate 51 to be snapped into the clamping interface 22. The connecting unit can move to the left or right, enabling the clamping plate 51 to be snapped into the clamping interface 22.

[0050] Embodiment Three:

[0051] In this embodiment, as Figures 7 - 9 shown, a clamping block 54 is also fixedly connected to the outer wall of the clamping plate 51 of the connecting unit 5, and opposite clamping openings 26 are respectively formed on the outer wall of the clamping interface 22. The clamping block 54 is embedded into the clamping opening 26 to form a mortise-and-tenon connection, which can fixedly connect the connecting unit 5 and the support unit 2.

[0052] In this embodiment, a clamping block 54 is fixedly connected to the outer wall of the clamping plate 51. Correspondingly, a clamping opening 26 adapted to it is formed on the outer wall of the clamping interface 22. After the clamping plate 51 is extended into the slotted opening 25, moving it to the left or right causes the clamping block 54 on the clamping plate 51 to be embedded into the clamping opening 26, forming a mortise-and-tenon connection. At this time, the fixation connection between the connecting frame and the support frame can be realized, effectively fixing the outer heat-insulating layer 8 of the HVAC pipe 7, and it is convenient for installation and disassembly, facilitating the replacement and maintenance of the heat-insulating layer 8.

[0053] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
