[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Specific embodiment:

[0028] As Figures 1-5As shown in the figure, a heat supply and ventilation pipe insulation structure includes a first protection member 1 and a second protection member 2. Both the first protection member 1 and the second protection member 2 are outer protection layers, and the first protection member 1 and the second protection member 2 are metal plates. Both the first protection member 1 and the second protection member 2 are arc-shaped and heat insulation members 3 are provided on their inner walls. The first protection member 1 and the second protection member 2 are connected by a first connection mechanism 4, so that the first protection member 1 and the second protection member 2 cooperate with the heat insulation member 3 to protect and insulate the heat supply and ventilation pipe body 5; second connection mechanisms 6 are provided at the ends of the first protection member 1 and the second protection member 2. Adjacent two insulation structures can be closely connected through the second connection mechanism 6, so that multiple insulation structures can cooperate to insulate the heat supply and ventilation pipe; the second connection mechanism 6 includes a first mounting member 61 fixedly connected to the outer side wall (left end) of one end of the first protection member 1 or the second protection member 2 and a second mounting member 62 fixedly connected to the outer side wall (right end) of the other end (right end) of the first protection member 1 or the second protection member 2. Both the first mounting member 61 and the second mounting member 62 are arc-shaped and their cross-sections are L-shaped. The end faces of the free ends of the first mounting member 61 and the second mounting member 62 are flush with the end faces of the first protection member 1 or the second protection member 2; a sliding arc plate 63 penetrates and slides on the first mounting member 61. One end of the sliding arc plate 63 is located in the opening of the first mounting member 61 and is fixedly connected with a mounting arc plate 64. The mounting arc plate 64 can be slidably inserted into the opening of the second mounting member 62. A connecting plate 65 is fixedly connected to the side of the first mounting member 61 close to the first connection mechanism 4. The connecting plate 65 and the sliding arc plate 63 are detachably connected by a bolt 66. Fit two adjacent insulation structures. At this time, the first mounting member 61 and the second mounting member 62 on the two adjacent insulation structures are mutually fitted. Push the sliding arc plate 63 to make the mounting arc plate 64 inserted into the opening between the second mounting member 62 and the first protection member 1 or the second protection member 2, and then connect the sliding arc plate 63 and the connecting plate 65 by the bolt 66. Then connect the first protection member 1 and the second protection member 2 through the first connection mechanism 4. Repeating this operation can connect between adjacent insulation structures, so that the insulation structures can be connected in cooperation to insulate the heat supply and ventilation pipe body 5.

[0029] As Figures 1-5 shown, a pulling opening 641 is provided on the sliding arc plate 63 to facilitate pulling the sliding arc plate 63.

[0030] As Figures 1-5 shown, along the length direction of the first protection member 1 or the second protection member 2, the length of the mounting arc plate 64 is greater than the length of the opening of the second mounting member 62, and the mounting arc plate 64 is made of heat insulation material, such as a foam plastic board. When the mounting arc plate 64 is inserted into the opening of the second mounting member 62, the mounting arc plate 64 can cover the joint between the two insulation structures and play a heat insulation effect.

[0031] As Figures 1-5As shown, on the same protection mechanism, at least two first connection mechanisms 4 are provided. In this embodiment, two are provided (the other first connection mechanism 4 is located directly below the first connection mechanism 4 shown in the figure); the first connection mechanism 4 includes a first connection member 41 provided on the first protection member 1 and a second connection member 42 provided on the second protection member 2. The first connection member 41 includes a mounting block 411 fixedly connected to the side wall of the first protection member 1. The mounting block 411 is recessed to form a mounting space. A slider 412 slides in the mounting block 411. The upper end surface of the slider 412 is fixedly connected to a cover plate 418. The cover plate 418 fits against the mounting block 411. Limiting chutes 413 are provided on both inner side walls of the mounting block 411. Both sides of the slider 412 slide in the limiting chutes 413. The second connection member 42 includes a fixing plate 421 fixedly connected to the outer side wall of the second protection member 2. An insertion block 422 is fixedly connected to the fixing plate 421. A first socket 414, which is adapted to the end of the insertion block 422 and communicates with the inside of the mounting block 411, is provided on one side of the mounting block 411 close to the insertion block 422, so that the insertion block 422 can be inserted into the first socket 414. An insertion bar 415 is fixedly connected to the slider 412. A second socket 416, which is adapted to the insertion bar 415, is provided on the mounting block 411. A third socket 423, which is adapted to the insertion bar 415, is provided on the insertion block 422. When the first protection member 1 and the second protection member 2 are brought close to each other and fit, at this time, the insertion block 422 just inserts into the mounting block 411. Then, when the insertion bar 415 is inserted into the second socket 416 and the third socket 423, the first protection member 1 and the second protection member 2 can be connected and fixed.

[0032] As Figures 1-5As shown, the first connecting member 41 further includes a spring 417 fixedly connected to the slider 412. An adjusting mechanism 7 for adjusting the tightness of the spring 417 is provided between the first connecting member 41 and the spring 417. The adjusting mechanism 7 includes a mounting ring 71 fixedly connected to the mounting block 411. The mounting ring 71 communicates with the inside of the mounting block 411. A threaded rod 72 is threadedly connected to the mounting ring 71. The adjusting mechanism 7 further includes an adjusting slide plate 73 slidably disposed in two limit chutes 413. The other end of the spring 417 is fixedly connected to the adjusting slide plate 73. One end of the threaded rod 72 located inside the mounting block 411 is rotatably connected to the adjusting slide plate 73 through a bearing seat (not shown in the figure). The end of the threaded rod 72 located outside the mounting block 411 is fixedly connected with a turning handle 74. When the spring 417 is in a normal state or a compressed state, the insert 415 can just be inserted into the second socket 416. By providing the spring 417, the insert 415 is not easily disengaged from the third socket 423, making the connection between the first protection member 1 and the second protection member 2 more stable. Inevitably, the spring 417 will become loose after being used multiple times or being in a compressed state for a long time. By rotating the turning handle 74 to rotate the threaded rod 72, the adjusting slide plate 73 can slide in the limit chute 413 under the restriction of the limit chute 413, thereby adjusting the tightness of the spring 417 and increasing the number of times the first connecting mechanism 4 can be used.

[0033] As Figures 1-5 shown, an insert 11 is fixedly connected to the side wall of the end of the first protection member 1 close to the second protection member 2. The insert 11 is made of a heat-insulating material, such as a foam plastic board. A slot 21 adapted to the insert 11 is formed in the side wall of the end of the second protection member 2 close to the first protection member 1. After the insert 11 is inserted into the first protection member 1 and the first protection member 1 and the second protection member 2 are connected, the insert 11 just fits into the slot 21. Since the insert 11 is inserted into the first protection member 1 and is made of a heat-insulating material, the heat-insulating effect at the connection between the first protection member 1 and the second protection member 2 can be improved.

[0034] As Figures 1-5 shown, the heat-insulating member 3 includes a first heat-insulating layer 31 fixedly connected to the inner wall of the first protection member 1 or the second protection member 2. The first heat-insulating layer 31 is made of a foam plastic board, a glass fiber board, etc. The first heat-insulating layer 31 can isolate the temperature exchange between the pipeline and the external environment and reduce the energy loss. A second heat-insulating layer 32 is fixedly connected to the inner wall of the first heat-insulating layer 31. The second heat-insulating layer 32 is used to fit the surface of the HVAC pipe body 5. The second heat-insulating layer 32 is a polyethylene layer, which can reduce the heat dissipation or cooling of the pipeline and improve the heat transfer efficiency of the pipeline.

[0035] The working principle of a heat supply and ventilation pipe insulation structure in this embodiment is as follows: Fit two adjacent insulation structures together. At this time, the first mounting member 61 and the second mounting member 62 on the two adjacent insulation structures are in contact with each other. Push the sliding arc plate 63 to insert the mounting arc plate 64 into the opening between the second mounting member 62 and the first protection member 1 or the second protection member 2. Then connect the sliding arc plate 63 and the connecting plate 65 through the bolt 66. After that, connect the first protection member 1 and the second protection member 2 through the first connecting mechanism 4. Repeating this operation can connect the adjacent insulation structures, enabling the cooperation and connection between the insulation structures to insulate the heat supply and ventilation pipe body 5; After connecting the first protection member 1 and the second protection member 2, the insertion strip 11 just inserts into the slot 21. Since the insertion strip 11 is embedded in the first protection member 1 and is made of heat-insulating material, it can improve the heat insulation effect at the connection of the first protection member 1 and the second protection member 2; Rotate the turning handle 74 to rotate the threaded rod 72. The sliding plate 73 can slide in the limiting chute 413 under its restriction, thereby adjusting the tightness of the spring 417 and increasing the service life of the first connecting mechanism 4; If it is necessary to disassemble a single insulation structure, remove the bolts 66 on this insulation structure and the adjacent insulation structure, and pull the corresponding sliding arc plate 63 to slide the mounting arc plate 64 out of the opening of the second mounting member 62. Then pull the cover plate 418 to make the insertion strip 415 disengage from the second socket 416 and the third socket 423, and the insulation structure to be removed can be disassembled.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art 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 in the protection scope of the present invention.
