Description

Technical Field

[0001] This utility model relates to the field of HVAC pipe technology, and in particular to an insulated HVAC pipe for HVAC engineering. Background Technology

[0002] In various buildings such as residences, office buildings, shopping malls, and hospitals, HVAC pipes are used for centralized heating, central air conditioning systems, and ventilation systems to provide people with a comfortable indoor environment and ensure air quality and temperature regulation within the building.

[0003] The insulation layer on the outside of existing HVAC pipes is usually fixed directly to the outside with glue. When the insulation layer needs to be repaired or replaced, it is difficult to remove due to the adhesive effect of the glue. Forcibly removing it may damage the surface of the HVAC pipe, thereby increasing maintenance costs and difficulty. At the same time, the assembly of traditional HVAC pipes requires a lot of time and cannot be quickly disassembled later, thus reducing the practicality of the pipes. Utility Model Content

[0004] Purpose of this utility model: The purpose of this utility model is to provide a solution to the problem that the insulation layer on the outside of existing HVAC pipes is generally fixed directly to the outside with glue, which makes it difficult to remove the insulation layer later. Forcible removal may damage the surface of the HVAC pipe, thereby increasing maintenance costs and difficulty. Another purpose of this utility model is to provide a solution to the problem that the assembly of traditional HVAC pipes requires a lot of time and cannot be quickly disassembled later.

[0005] Technical solution: A heat-insulated HVAC pipe for HVAC engineering, comprising two HVAC pipe bodies, each having a connecting plate fixedly connected to its front surface, a U-shaped plate fixedly connected to the front surface of the connecting plate, and an insulation layer fitted onto the outer wall of the HVAC pipe body.

[0006] The front surface of the U-shaped plate is integrally formed with multiple engaging circular holes. A rotating disk is provided in front of each of the multiple engaging circular holes. A rotating column is fixedly connected to the center of the rear surface of the rotating disk. The rotating column is located inside the engaging circular holes. A connecting rod is rotatably connected to the center of the rear surface of the rotating column via a rotating shaft. The rear end of the connecting rod extends to the inner side of the U-shaped plate and is fixedly connected to a clamping plate.

[0007] Furthermore, each of the multiple engaging circular holes has a sliding groove on its inner lower surface, and each of the multiple engaging circular holes has an arc-shaped slot on its inner left side. Each of the multiple rotating columns has a locking block fixedly connected to its outer side wall. The outer side walls of the multiple locking blocks are slidably connected to the interior of the multiple arc-shaped slots. Each of the multiple clamping plates has a multiple spring fixedly connected to its inner side wall.

[0008] Furthermore, a splicing ring is provided between the two HVAC pipe bodies. Insertion rings are fixedly connected to the left and right sides of the splicing ring. The opposite sides of the two insertion rings extend into the interior of the two HVAC pipe bodies. A curved movable cavity is symmetrically formed inside the insertion ring. A curved plate is slidably connected inside each of the two curved movable cavities. Insertion blocks are fixedly connected to the opposite sides of the two curved plates. Fixing grooves are symmetrically formed on the left and right sides of the interior of the two HVAC pipe bodies. Multiple insertion blocks, on the side furthest from the multiple curved plates, extend into the interior of the multiple fixing grooves.

[0009] Furthermore, a rubber layer is fixedly connected to the rear surface of each of the multiple clamping plates, and the rear surface of each of the multiple rubber layers is in close contact with the insulation layer.

[0010] Furthermore, the splicing ring has symmetrical arc-shaped movable cavities II on its inner left and inner right sides. Arc-shaped plates II are slidably connected inside each of the multiple arc-shaped movable cavities II. Screws are rotatably connected to the outer sides of each of the multiple arc-shaped plates II via rotating shafts. The ends of the multiple screws away from the multiple arc-shaped plates II extend to the outer side of the splicing ring and are fixedly connected to operating handles. Air delivery grooves are respectively formed inside the multiple arc-shaped movable cavities II and the multiple arc-shaped movable cavities I.

[0011] Furthermore, sealing gaskets are fixedly connected to the left and right sides of the splicing rings, and the left and right sides of the two sealing gaskets are in close contact with the opposite sides of the two HVAC pipe bodies, respectively.

[0012] Furthermore, the front and rear surfaces of the splicing ring are symmetrically provided with storage holes, and the multiple operating handles are respectively located inside the multiple storage holes.

[0013] Beneficial effects: By rotating multiple rotating discs in sequence, the rotating column, connecting rod and clamping plate are driven to move together, which can quickly clamp or loosen the insulation layer, completely solving the removal problem caused by traditional glue fixation, avoiding damage to the surface of HVAC pipes during removal, greatly reducing maintenance costs and difficulty. At the same time, the rubber layer on the back surface of the clamping plate increases the friction with the insulation layer to prevent it from sliding, and its softness avoids wear on the insulation layer. In addition, the spring provides buffer and continuous clamping force, making the insulation layer more firmly fixed and effectively extending the service life of the insulation layer.

[0014] After the plug-in rings on both sides of the splicing ring are inserted into the HVAC pipe body, turning the operating handle causes the screw, arc plate two, air delivery groove, arc plate one, and plug-in block to work together to quickly insert the plug-in block into the fixing groove to complete the connection. Reversing the operation allows for quick disassembly, greatly shortening assembly and disassembly time and improving construction efficiency. Furthermore, the plug-in block fits tightly with the fixing groove to prevent pipe loosening and detachment, and the sealing gasket effectively prevents media leakage and external impurities from entering, ensuring normal system operation. Its elasticity also buffers stress and enhances connection stability. Attached Figure Description

[0022] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1 and Figure 3As shown, a splicing ring 14 is provided between two HVAC pipe bodies 1. Insertion rings 15 are fixedly connected to the left and right sides of the splicing ring 14. The opposite sides of the two insertion rings 15 extend into the interior of the two HVAC pipe bodies 1. Arc-shaped movable cavities 16 are symmetrically opened inside the insertion rings 15. Arc-shaped plates 17 are slidably connected inside the two arc-shaped movable cavities 16. Insertion blocks 18 are fixedly connected to the opposite sides of the two arc-shaped plates 17. Fixing grooves 19 are symmetrically opened on the left and right sides of the interior of the two HVAC pipe bodies 1. Multiple insertion blocks 18 extend into the interior of multiple fixing grooves 19 on the side away from the multiple arc-shaped plates 17.

[0025] First, place the splicing ring 14 between the two HVAC pipe bodies 1 to be connected, ensuring that the insertion rings 15 on both sides of the splicing ring 14 are precisely aligned with the ports of the HVAC pipe bodies 1. Then, push the two HVAC pipe bodies 1 towards the splicing ring 14 to begin the connection. When the two insertion rings 15 are inserted into the HVAC pipe bodies 1, by controlling the extension of multiple insertion blocks 18, the multiple insertion blocks 18 can be inserted into the interior of multiple fixing slots 19 respectively, thereby completing the rapid fixation of the two HVAC pipe bodies 1. The whole process does not require complicated tools and cumbersome steps, is simple to operate, and greatly improves the installation efficiency.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an insulated HVAC pipe for HVAC engineering is provided, including two HVAC pipe bodies 1. A connecting plate 2 is fixedly connected to the front surface of each of the two HVAC pipe bodies 1. A U-shaped plate 3 is fixedly connected to the front surface of the connecting plate 2. An insulation layer 4 is fitted onto the outer wall of the HVAC pipe body 1. Multiple engaging circular holes 5 are integrally formed on the front surface of the U-shaped plate 3. A rotating disk 6 is provided in front of each of the engaging circular holes 5. A rotating column 7 is fixedly connected to the center of the rear surface of the rotating disk 6. The rotating column 7 is located inside the engaging circular holes 5. A connecting rod 8 is rotatably connected to the center via a pivot. The rear end of the connecting rod 8 extends to the inner side of the U-shaped plate 3 and is fixedly connected to a clamping plate 9. The lower inner surface of multiple engaging circular holes 5 is provided with a sliding groove 10. The inner side of multiple engaging circular holes 5 and the left side of multiple sliding grooves 10 is provided with an arc-shaped groove 11. The upper outer side wall of multiple rotating columns 7 is fixedly connected with a locking block 12. The outer side wall of multiple locking blocks 12 is slidably connected to the inner side of multiple arc-shaped grooves 11. The front surface of multiple clamping plates 9 is fixedly connected to the inner side wall of the U-shaped plate 3 with multiple springs 13.

[0027] First, cut the insulation layer 4 according to the circumference of the HVAC pipe body 1. Place one end of the insulation layer 4 into the slot formed between the U-shaped plate 3 and the connecting plate 2. Then, push the leftmost and rightmost rotating disks 6 to insert the rotating column 7 at the center of the rear surface of the rotating disk 6 into the engaging circular hole 5 on the front surface of the U-shaped plate 3. At the same time, make the locking block 12 slide along the slide groove 10. When the rotating column 7 moves, it drives the clamping plate 9 to gradually approach the insulation layer 4 through the connecting rod 8 until it clamps both sides. Finally, rotate the rotating disk 6, and the rotating column 7 drives the locking block 12 to rotate in the arc-shaped slot 11. Because the locking block 12 and the arc-shaped slot 11 are in close contact, the locking block 12 rotates within the arc-shaped slot 11. With the cooperation of the slot 11, the rotating column 7 will be effectively limited and fixed. At the same time, when the clamping plate 9 moves, the spring 13 is compressed. After the two ends of the insulation layer 4 are clamped and fixed, the middle part can be clamped. After one end is clamped and fixed, the other end of the insulation layer 4 is inserted into the other slot formed by the U-shaped plate 3 and the connecting plate 2. Repeat the above process to fix the insulation layer 4 on the outside of the HVAC pipe body 1. When the insulation layer 4 needs to be replaced, after rotating the multiple rotating disks 6 in the opposite direction, the elastic force of the multiple springs 13 can assist the multiple clamping plates 9 to reset, thereby canceling the clamping and fixing of the two ends of the insulation layer 4.

[0028] like Figure 5 As shown, rubber layers 20 are fixedly connected to the rear surfaces of multiple clamping plates 9, and the rear surfaces of multiple rubber layers 20 are in close contact with the insulation layer 4.

[0029] The multiple rubber layers 20 effectively prevent the insulation layer 4 from shifting under the clamping of the clamping plate 9, further improving the stability of the insulation layer 4. At the same time, the rubber layers 20 are soft and have a certain degree of elasticity. When in contact with the insulation layer 4, they can prevent the clamping plate 9 from causing hard damage to the insulation layer 4 directly, thereby extending the service life of the insulation layer 4.

[0030] like Figure 1 and Figure 3 As shown, sealing gaskets 26 are fixedly connected to the left and right sides of the splicing ring 14 and located on the outside of the two splicing rings 14. The left and right sides of the two sealing gaskets 26 are in close contact with the opposite sides of the two HVAC pipe bodies 1, respectively.

[0031] When two HVAC pipe bodies 1 are connected by splicing ring 14, they are tightly pressed at the connection between splicing ring 14 and HVAC pipe body 1, which can effectively prevent the medium from seeping out from the connection, ensure the normal operation of the HVAC system, avoid energy loss or impact on the surrounding environment due to medium leakage, and at the same time prevent dust, water vapor and other impurities from entering the HVAC pipe, avoid impurities from polluting the medium inside the pipe, or affect the flow performance of the pipe and the normal operation of the equipment due to the accumulation of impurities.

[0032] like Figure 6As shown, the splicing ring 14 has symmetrical arc-shaped movable cavities 21 on its left and right sides. Arc-shaped plates 22 are slidably connected inside each of the multiple arc-shaped movable cavities 21. Screws 23 are rotatably connected to the outer sides of the multiple arc-shaped plates 22 via a rotating shaft. The ends of the multiple screws 23 away from the multiple arc-shaped plates 22 extend to the outer side of the splicing ring 14 and are fixedly connected to an operating handle 24. Air delivery grooves 25 are respectively opened inside the multiple arc-shaped movable cavities 21 and the multiple arc-shaped movable cavities 16.

[0033] Initially, multiple plug-in blocks 18 are located inside multiple arc-shaped movable cavities 16. After the two plug-in rings 15 are aligned and connected to the inside of the two HVAC pipe bodies 1, the screws 23 of the multiple rotating operation handles 24 are rotated in sequence. Since the screws 23 are connected to the arc-shaped plate 22 through the rotating shaft, the rotation of the screws 23 will push the arc-shaped plate 22 to slide in the arc-shaped movable cavity 21. The sliding of the arc-shaped plate 22 will change the air pressure in the arc-shaped movable cavity 21. The gas is transmitted from the arc-shaped movable cavity 21 to the arc-shaped movable cavity 16 through the gas delivery groove 25. The change in air pressure in the arc-shaped movable cavity 16 pushes the arc-shaped plate 17 to slide in the arc-shaped movable cavity 16, thereby causing the plug-in block 18 on the opposite side of the arc-shaped plate 17 to move outward and insert into the fixing groove 19 inside the HVAC pipe body 1, thus completing the fixing of the two HVAC pipe bodies 1. No complicated tools or professional skills are required, which is convenient for construction personnel to operate and improves installation efficiency.

[0034] like Figure 6 As shown, the front and rear surfaces of the splicing ring 14 are symmetrically provided with storage holes 27, and multiple operating handles 24 are located inside the multiple storage holes 27 respectively.

[0035] After the operation is completed, rotate the operating handle 24 into the storage hole 27 so that there are no more protruding handles around the entire splicing ring 14. This avoids the operating handle 24 taking up extra space during installation or subsequent maintenance, reducing the risk of collision with other equipment or construction materials. At the same time, the storage hole 27 makes the splicing ring 14 look neater and more orderly, coordinating with the overall HVAC system, and the protruding operating handle 24 will not affect the overall layout and visual effect.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
