Description

Technical Field

[0001] This utility model relates to an easily installed and spliced ​​insulated pipe for HVAC engineering, belonging to the field of pipe installation technology. Background Technology

[0002] Insulated pipes in HVAC engineering refer to pipe systems used to maintain the temperature of the medium inside the pipe and prevent heat loss. Insulated pipes play a vital role in HVAC engineering, mainly used to transport media such as steam or hot water, ensuring that the medium maintains a certain temperature during transportation, thereby meeting heating or process requirements.

[0003] Existing patents feature a plug-in splicing structure that eliminates the need for bolts, facilitating easy assembly and disassembly, saving time and effort. This structure also incorporates a guiding function to prevent misalignment during pipe splicing. This invention features a pipe reinforcement structure that effectively improves the pipe's compressive strength. The insulation structure is designed for assembly, allowing for separate production of components before assembly, preventing the entire insulation pipe from being scrapped due to errors in a single process. This method also has lower technical requirements and facilitates later inspection and maintenance. However, because the components are produced separately, each component must be installed individually during the splicing and installation of the insulation pipe, increasing workload and reducing installation efficiency. Furthermore, the large number of component types increases production costs. Additionally, this device cannot securely install the insulation pipe within pre-drilled trenches, making it difficult to guarantee the stability of the installed pipe. Existing pipe fixing methods primarily rely on backfilling, which increases the difficulty of later maintenance and replacement, hindering stable installation and subsequent maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide an insulated pipe for HVAC engineering that is easy to install and splice, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An easily installed and spliced ​​insulated pipe for HVAC engineering includes a splicing sleeve, pipe ends, and an insulated pipe body. The splicing sleeve has pipe ends at both its inner left and right ends, and the outer ends of the pipe ends are sealed to the insulated pipe body. Sliding compression sleeves are slidably connected to both the left and right ends of the outer side of the splicing sleeve. A pressure-bearing triangular plate is slidably connected to the inner side of the sliding compression sleeve. A pressure-bearing sliding rod is fixedly connected to the inner end face of the pressure-bearing triangular plate, and a lifting block is fixedly connected to the inner end of the pressure-bearing sliding rod. The pressure-bearing triangular plate, pressure-bearing sliding rod, and lifting block are all slidably connected to the splicing sleeve. The lifting block is slidably connected to the pipe ends. Installation sleeves are provided at the middle positions of the upper and lower ends of the splicing sleeve. An adjusting screw is spirally connected to the inner side of the installation sleeve, and a side support plate is provided at the outer end of the adjusting screw.

[0007] Furthermore, a sealing ring is provided between the splicing pipe sleeve and the pipe head for a sealing connection.

[0008] Furthermore, a limiting groove is provided on the outer side of the tube head, and the position and size of the limiting groove correspond to the position and size of the lifting block.

[0009] Furthermore, the upper surface of the pressure-bearing slide bar is covered with a first spring.

[0010] Furthermore, a second spring is fixedly connected to both the left and right sides of the inner sidewall of the splicing pipe sleeve. A limiting block is provided at the outer end of the second spring. The limiting block is slidably connected to the splicing pipe sleeve. The limiting block is fitted to the sliding extrusion sleeve. A guide protrusion is provided on the outer side of the splicing pipe sleeve. The guide protrusion is slidably connected to the sliding extrusion sleeve.

[0011] Furthermore, the inner end of the mounting sleeve is fixedly connected to a mounting thread head, which is spirally connected to the splicing sleeve, and a third spring is provided inside the mounting sleeve.

[0012] Furthermore, a hexagonal adjusting block is fixedly connected to the outer end of the adjusting screw, and a plug is fixedly connected to the outer end of the hexagonal adjusting block. The plug is slidably connected to the side support plate, and anti-slip teeth are fixedly connected to the outer end face of the side support plate.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a splicing sleeve to allow the end of the insulated pipe to be inserted and sealed with a sealing ring. Pulling the sliding compression sleeve outward causes the pressure-bearing triangular plate to slide inward, and the pressure-bearing slide rod moves the lifting block inward, inserting it into the limiting groove inside the pipe end. This achieves rapid fixing of the insulated pipe. The elasticity of the second spring causes the sliding compression sleeve to move outward, after which the limiting block automatically pops out and limits the sliding compression sleeve inward, thus improving the ease of installation and splicing of the insulated pipe. The invention also utilizes an installation threaded head to install the installation sleeve on the upper and lower sides of the splicing sleeve. Rotating the hexagonal adjusting block allows the adjusting screw to move spirally, and the plug connects the hexagonal adjusting block to the side support plate, pressing it down. This allows the side support plate to be fixed in the pre-cut pipe groove by the anti-slip teeth and the inner pressing action, improving the installation stability of the insulated pipe and facilitating subsequent maintenance, disassembly, and replacement.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Example 1 Figures 1-4 This utility model provides a technical solution:

[0023] An easily installed and spliced ​​insulated pipe for HVAC engineering includes a splicing sleeve 1, pipe ends 2, and an insulated pipe body 3. Pipe ends 2 are located at both ends of the inner side of the splicing sleeve 1. The outer ends of the pipe ends 2 are sealed to the insulated pipe body 3. Sliding compression sleeves 4 are slidably connected to both ends of the outer side of the splicing sleeve 1. A pressure-bearing triangular plate 5 is slidably connected to the inner side of the sliding compression sleeve 4. A pressure-bearing sliding rod 6 is fixedly connected to the inner end face of the pressure-bearing triangular plate 5. A lifting rod is fixedly connected to the inner end of the pressure-bearing sliding rod 6. The lowering block 7, the pressure-bearing triangular plate 5, the pressure-bearing slide rod 6, and the lifting block 7 are all slidably connected to the splicing pipe sleeve 1. The lifting block 7 is slidably connected to the pipe head 2. A sealing ring 11 is used to seal the splicing pipe sleeve 1 and the pipe head 2. A limit groove 12 is opened on the outer side of the pipe head 2. The position and size of the limit groove 12 correspond to the position and size of the lifting block 7. The upper side of the pressure-bearing slide rod 6 is covered with a first spring 13. The left and right sides of the side wall of the splicing pipe sleeve 1 are fixedly connected. A second spring 14 is connected, and a limiting block 15 is provided at the outer end of the second spring 14. The limiting block 15 is slidably connected to the splicing pipe sleeve 1 and is fitted to the sliding compression sleeve 4. A guide protrusion 16 is provided on the outer side of the splicing pipe sleeve 1, and the guide protrusion 16 is slidably connected to the sliding compression sleeve 4. By setting the splicing pipe sleeve 1, the end pipe head 2 of the insulation pipe body 3 can be inserted into it and sealed by the sealing ring 11. By pulling the sliding compression sleeve 4 outward, the pressure-bearing triangular plate 5 can be driven to slide inward, and the pressure-bearing slide rod 6 can drive the lifting block 7 to move inward and insert it into the limiting slot 12 inside the pipe head 2, thereby realizing the rapid fixing of the insulation pipe body 3. After the sliding compression sleeve 4 moves outward due to the elasticity of the second spring 14, the limiting block 15 can automatically pop out and limit the sliding compression sleeve 4 inward, thereby improving the convenience of installation and splicing of the insulation pipe.

[0024] Please refer to Example 2 Figure 1 and Figure 4The difference between this embodiment and Embodiment 1 is that: Installation sleeves 8 are provided at the middle positions of both the upper and lower ends of the splicing pipe sleeve 1; an adjusting screw 9 is spirally connected to the inner side of the installation sleeve 8; a side support plate 10 is provided at the outer end of the adjusting screw 9; an installation threaded head 17 is fixedly connected to the inner end of the installation sleeve 8; the installation threaded head 17 is spirally connected to the splicing pipe sleeve 1; a third spring 18 is provided inside the installation sleeve 8; a hexagonal adjusting block 19 is fixedly connected to the outer end of the adjusting screw 9; a plug 20 is fixedly connected to the outer end of the hexagonal adjusting block 19; the plug 20 is slidably connected to the side support plate 10; and the side... The outer end face of the support plate 10 is fixedly connected with anti-slip teeth 21. The installation sleeve 8 can be installed on the upper and lower sides of the splicing pipe sleeve 1 by using the installation thread head 17. The adjustment screw 9 can be moved spirally by rotating the hexagonal adjustment block 19. The hexagonal adjustment block 19 can be connected to the side support plate 10 by the plug 20 and press against the side support plate 10. The side support plate 10 can be fixed in the pre-cut pipe groove by the anti-slip teeth 21 and the inner pressing action, which improves the installation stability of the insulation pipe body 3 and facilitates subsequent maintenance, disassembly and replacement.

[0025] The working principle of this utility model is as follows: When in use, the splicing sleeve 1 allows the end of the insulation pipe 3, the pipe head 2, to be inserted into it. A sealing ring 11 is used for a butt seal. Pulling the sliding compression sleeve 4 outward causes the pressure-bearing triangular plate 5 to slide inward, causing the pressure-bearing slide rod 6 to move the lifting block 7 inward and insert it into the limiting slot 12 inside the pipe head 2, thus quickly fixing the insulation pipe 3. The elasticity of the second spring 14 causes the sliding compression sleeve 4 to move outward, after which the limiting block 15 automatically pops out and applies pressure to the sliding compression sleeve 3. The sleeve 4 is internally limited to improve the ease of installation and splicing of the insulated pipe. The installation thread head 17 allows the installation sleeve 8 to be installed on the upper and lower sides of the splicing sleeve 1. The adjustment screw 9 can be moved spirally by rotating the hexagonal adjustment block 19. The plug 20 allows the hexagonal adjustment block 19 to be connected to the side support plate 10 and press against it. The side support plate 10 is then fixed in the pre-cut pipe groove by the anti-slip teeth 21 and the internal pressing action, which improves the installation stability of the insulated pipe body 3 and facilitates subsequent maintenance, disassembly and replacement.
