Description

Technical Field

[0001] This utility model relates to the field of heat pump unit technology, and in particular to a pipeline connection structure for a heat pump unit. Background Technology

[0002] In practical applications of heat pump units, the adaptability and stability of the piping connection structure are crucial. Traditional heat pump unit piping connections often employ a fixed installation method, making it difficult to flexibly adjust to different installation environments, equipment layouts, and piping routing requirements. When faced with diverse installation scenarios, this fixed structure not only requires significant time for redesign and modification, increasing installation costs and construction difficulty, but also makes it difficult to guarantee the stability and accuracy of the installed system, severely impacting the installation efficiency and performance of the heat pump unit.

[0003] Therefore, we propose a piping connection structure for heat pump units. Utility Model Content

[0004] The main purpose of this utility model is to provide a pipe connection structure for heat pump units to prevent the problem of difficulty in adapting to diverse installation scenarios due to fixed installation structures, avoid spending a lot of time on redesign and modification, and reduce installation costs and construction difficulties; at the same time, it prevents the occurrence of insufficient stability and accuracy of the pipe connection structure after installation, thereby improving the installation efficiency and performance of heat pump units, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A pipeline connection structure for a heat pump unit includes a connecting plate. An extension sleeve is slidably installed on the top and bottom of the outer side of the connecting plate. A plurality of first threaded holes are vertically arranged at equal intervals on the connecting plate. Two extension sleeves are provided with bolt through holes for connecting with first fixing bolts on the side near the first threaded holes. One end of the first fixing bolt passes through the bolt through hole and is threadedly connected to the first threaded hole.

[0007] The top and bottom ends of the two extension sleeves are respectively provided with translation mechanisms. The translation mechanism includes a support plate, a base and a guide slider. The top and bottom ends of the two bases are respectively provided with left and right moving fixing mechanisms.

[0008] By adopting the above technical solution, if it is necessary to adjust the position of the extension sleeve on the connecting plate to adapt to different installation requirements, the first fixing bolt can be unscrewed first, so that the extension sleeve slides vertically along the connecting plate. The sliding cooperation between the limiting block and the limiting groove ensures that the sliding process is smooth and does not deviate. When the extension sleeve slides to a suitable height, the first fixing bolt is passed through the bolt hole on the extension sleeve and screwed into the first threaded hole at the corresponding height on the connecting plate to complete the fixing of the extension sleeve position and realize the vertical height adaptation adjustment of the device.

[0009] Furthermore, a limiting block is fixedly connected to the upper and lower parts of one side of the connecting plate, and a limiting groove is provided on one side of each of the two extension sleeves to slide with the limiting block.

[0010] By adopting the above technical solution, when the extension sleeve slides along the connecting plate to adjust its position, the cooperation between the limiting block and the limiting groove can restrict the sliding direction of the extension sleeve, ensuring that the extension sleeve can only move in the specified direction and preventing it from deviating, thereby improving the stability and accuracy of the sliding installation of the extension sleeve.

[0011] Furthermore, the top and bottom ends of the two support plates are fixedly connected to the bottom and top ends of the extension sleeve, respectively. Guide grooves are provided on both sides of the upper and lower surfaces of the two support plates. Rod through ports are provided on both sides of the two support plates. A fixing screw is inserted through the rod through port. A first fixing nut is threaded to one end of the fixing screw. The two bases are located on the upper and lower surfaces of the two support plates and are symmetrically arranged. Two symmetrical guide sliders are fixedly connected to the top and bottom ends of the two bases, respectively.

[0012] By adopting the above technical solution, the guide slider on the base is aligned with the guide groove on the support plate, and the guide slider is embedded in the guide groove, so that the base can slide left and right along the guide groove on the surface of the support plate; when the base slides to the appropriate position, the fixing screw is passed through the through-rod port and the screw through hole on the guide slider, and then the first fixing nut is tightened to fix the base on the support plate, thus completing the installation and position adjustment of the base on the support plate.

[0013] Furthermore, the guide groove is connected to the through rod port, and a screw through hole is provided on the guide slider. The base slides left and right in the guide groove through the guide slider, and is limited after being locked by the fixing screw passing through the screw through hole and the first fixing nut.

[0014] By adopting the above technical solution, when the position of the base needs to be adjusted, the first fixing nut is loosened so that the fixing screw no longer applies locking force to the guide slider. At this time, the base can slide freely left and right in the guide groove through the guide slider, which is convenient to adjust the position of the base according to the actual pipeline layout requirements. When the base slides to the required position, the first fixing nut is tightened. Through the cooperation of the fixing screw and the first fixing nut, the guide slider is firmly fixed to the support plate, thereby locking the position of the base and ensuring that the base will not be displaced during subsequent use.

[0015] Furthermore, the fixing mechanism includes a first arc-shaped fixing sleeve that is fixedly connected to the top and bottom of the two bases respectively, and a second arc-shaped fixing sleeve that fixes the fixing pipe is respectively fitted to the top and bottom of the two first arc-shaped fixing sleeves. The inner sides of the first arc-shaped fixing sleeve and the second arc-shaped fixing sleeve are provided with anti-slip pads.

[0016] By adopting the above technical solution, the pipeline to be fixed is placed in the arc-shaped groove of the first arc-shaped fixing sleeve, and then the second arc-shaped fixing sleeve is placed on the pipeline, so that the first arc-shaped fixing sleeve and the second arc-shaped fixing sleeve are spliced ​​together to form a complete circle, tightly wrapping the pipeline. Since the anti-slip pads on the inner side of the first arc-shaped fixing sleeve and the second arc-shaped fixing sleeve can increase the friction between them and the pipeline, the pipeline is prevented from sliding in the fixing sleeve, thereby improving the fixing effect of the pipeline and ensuring the firmness of the pipeline installation.

[0017] Furthermore, both the first arc-shaped fixing sleeve and the second arc-shaped fixing sleeve have two symmetrical second threaded holes on their sides. The second threaded holes are threaded with second fixing bolts, and the second fixing bolts extend to the outside and are threaded with second fixing nuts.

[0018] By adopting the above technical solution, the pipeline to be fixed is placed in the arc-shaped groove of the first arc-shaped fixing sleeve, and then the second arc-shaped fixing sleeve is placed on the pipeline, so that the first arc-shaped fixing sleeve and the second arc-shaped fixing sleeve are spliced ​​together to form a complete circle, tightly wrapping the pipeline. Since the anti-slip pads on the inner side of the first arc-shaped fixing sleeve and the second arc-shaped fixing sleeve can increase the friction between them and the pipeline, the pipeline is prevented from sliding in the fixing sleeve, thereby improving the fixing effect of the pipeline and ensuring the firmness of the pipeline installation.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) This utility model discloses a pipeline connection structure for a heat pump unit. By setting an extension sleeve that can slide vertically on the connecting plate, and cooperating with the connection structure of the first threaded hole, bolt through hole and the first fixing bolt, as well as the guiding cooperation of the limiting block and the limiting groove, the vertical height of the extension sleeve can be flexibly adjusted. In the actual installation process, simply unscrew the first fixing bolt to allow the extension sleeve to slide along the connecting plate. After reaching the appropriate height, tighten the fixing bolt to complete the fixation. This effectively solves the problem of the traditional structure having a fixed vertical position and being difficult to adapt to different installation heights, and significantly improves the versatility and installation efficiency of the device.

[0021] (2) This utility model discloses a pipeline connection structure for a heat pump unit. The cooperative design of the support plate, base, and guide slider in the translation mechanism allows the base to slide left and right on the surface of the support plate, and its position is locked by the fixing screw and the first fixing nut. When it is necessary to adjust the lateral layout of the pipeline, the base can slide freely by loosening the first fixing nut, and the nut can be tightened after adjustment to achieve precise fixation. This precise adjustment function of the lateral position can better adapt to the needs of complex pipeline routing, optimize the pipeline connection layout, and ensure the stability of the base during use, effectively improving the practicality and reliability of the pipeline connection structure of the heat pump unit.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] To prevent issues arising from a fixed installation structure that makes it difficult to adapt to diverse installation scenarios, avoid spending significant time on redesign and modification, and reduce installation costs and construction difficulty; simultaneously, to prevent insufficient stability and accuracy of the pipe connection structure after installation, thereby improving the installation efficiency and performance of the heat pump unit, such as... Figure 1 , Figure 2 , Figure 3 As shown, a pipeline connection structure for a heat pump unit includes a connecting plate 1. An extension sleeve 2 is slidably installed on the top and bottom of the outer side of the connecting plate 1. A plurality of first threaded holes 3 are vertically arranged at equal intervals on the connecting plate 1. Two extension sleeves 2 are provided with bolt through holes 5 on the side near the first threaded holes 3, which are connected to a first fixing bolt 4. One end of the first fixing bolt 4 passes through the bolt through hole 5 and is threadedly connected to the first threaded hole 3.

[0029] The top and bottom ends of the two extension sleeves 2 are respectively provided with translation mechanisms 6. The translation mechanism 6 includes a support plate 8, a base 13 and a guide slider 14. The top and bottom ends of the two bases 13 are respectively provided with left and right moving fixing mechanisms 7.

[0030] When in use, if it is necessary to adjust the position of the extension sleeve 2 on the connecting plate 1 to adapt to different installation requirements, the first fixing bolt 4 can be unscrewed first, so that the extension sleeve 2 slides vertically along the connecting plate 1. The sliding cooperation between the limiting block 21 and the limiting groove 22 ensures that the sliding process is smooth and does not deviate. When the extension sleeve 2 slides to a suitable height, the first fixing bolt 4 is passed through the bolt hole 5 on the extension sleeve 2 and screwed into the first threaded hole 3 at the corresponding height on the connecting plate 1 to complete the position fixation of the extension sleeve 2 and realize the vertical height adaptation adjustment of the device.

[0031] For example, such as Figure 2 As shown, the present invention also includes a limiting block 21 fixedly connected to the upper and lower parts of one side of the connecting plate 1, and a limiting groove 22 that slides with the limiting block 21 is provided on one side of each of the two extension sleeves 2.

[0032] When the extension sleeve 2 slides along the connecting plate 1 to adjust its position during use, the cooperation between the limiting block 21 and the limiting groove 22 can restrict the sliding direction of the extension sleeve 2, ensuring that the extension sleeve 2 can only move in the specified direction and preventing it from deviating, thereby improving the stability and accuracy of the sliding installation of the extension sleeve 2.

[0033] For example, such as Figure 1 , Figure 3As shown, this utility model also includes the top and bottom ends of the two support plates 8 being fixedly connected to the bottom and top ends of the extension sleeve 2, respectively. Guide grooves 9 are respectively provided on both sides of the upper and lower surfaces of the two support plates 8. Rod ports 10 are provided on both sides of the two support plates 8. A fixing screw 11 is inserted inside the rod port 10. A first fixing nut 12 is threaded to one end of the fixing screw 11. The two bases 13 are respectively located on the upper and lower surfaces of the two support plates 8 and are symmetrically arranged. Two symmetrical guide sliders 14 are fixedly connected to the top and bottom ends of the two bases 13, respectively.

[0034] In use, align the guide slider 14 on the base 13 with the guide groove 9 on the support plate 8, and insert the guide slider 14 into the guide groove 9 so that the base 13 can slide left and right along the guide groove 9 on the surface of the support plate 8; when the base 13 slides to the appropriate position, pass the fixing screw 11 through the through rod port 10 and the screw through hole 15 on the guide slider 14, and then fix the base 13 on the support plate 8 by tightening the first fixing nut 12, thus completing the installation and position adjustment of the base 13 on the support plate 8.

[0035] For example, such as Figure 3 As shown, the present invention also includes that the guide groove 9 is connected to the rod port 10, the guide slider 14 is provided with a screw through hole 15, the base 13 slides left and right in the guide groove 9 through the guide slider 14, and is locked and limited by the fixing screw 11 passing through the screw through hole 15 and the first fixing nut 12.

[0036] When adjusting the position of the base 13 during use, loosen the first fixing nut 12 so that the fixing screw 11 no longer applies locking force to the guide slider 14. At this time, the base 13 can slide freely left and right in the guide groove 9 through the guide slider 14, which is convenient to adjust the position of the base 13 according to the actual pipeline layout requirements. After the base 13 slides to the required position, tighten the first fixing nut 12. Through the cooperation of the fixing screw 11 and the first fixing nut 12, the guide slider 14 is firmly fixed on the support plate 8, thereby locking the position of the base 13 and ensuring that the base 13 will not be displaced during subsequent use.

[0037] For example, such as Figure 4 As shown, the present invention also includes the fixing mechanism 7, which includes a first arc-shaped fixing sleeve 16 that is fixedly connected to the top and bottom of the two bases 13 respectively, and a second arc-shaped fixing sleeve 17 that is fitted to the top and bottom of the two first arc-shaped fixing sleeves 16 respectively to fix the fixing pipe. The inner sides of the first arc-shaped fixing sleeve 16 and the second arc-shaped fixing sleeve 17 are provided with anti-slip pads 23.

[0038] In use, the pipe to be fixed is placed in the arc-shaped groove of the first arc-shaped fixing sleeve 16, and then the second arc-shaped fixing sleeve 17 is placed on the pipe so that the first arc-shaped fixing sleeve 16 and the second arc-shaped fixing sleeve 17 are spliced ​​together to form a complete circle, tightly wrapping the pipe. Since the anti-slip pads 23 on the inner side of the first arc-shaped fixing sleeve 16 and the second arc-shaped fixing sleeve 17 can increase the friction between them and the pipe, the pipe is prevented from sliding in the fixing sleeve, thereby improving the fixing effect of the pipe and ensuring the firmness of the pipe installation.

[0039] For example, such as Figure 4 As shown, the present invention also includes two symmetrical second threaded holes 18 on both sides of the first arc-shaped fixing sleeve 16 and the second arc-shaped fixing sleeve 17. The second threaded holes 18 are internally threaded with second fixing bolts 19, and the second fixing bolts 19 extend to the outside and are threaded with second fixing nuts 20.

[0040] In use, the pipe to be fixed is placed in the arc-shaped groove of the first arc-shaped fixing sleeve 16, and then the second arc-shaped fixing sleeve 17 is placed on the pipe so that the first arc-shaped fixing sleeve 16 and the second arc-shaped fixing sleeve 17 are spliced ​​together to form a complete circle, tightly wrapping the pipe. Since the anti-slip pads 23 on the inner side of the first arc-shaped fixing sleeve 16 and the second arc-shaped fixing sleeve 17 can increase the friction between them and the pipe, the pipe is prevented from sliding in the fixing sleeve, thereby improving the fixing effect of the pipe and ensuring the firmness of the pipe installation.

[0041] It should be noted that this utility model is a pipeline connection structure for a heat pump unit. First, unscrew the first fixing bolt 4 to allow the extension sleeve 2 to slide vertically along the connecting plate 1. The limiting block 21 and the limiting groove 22 cooperate to ensure stability. After sliding to a suitable height, the first fixing bolt 4 is passed through the bolt through hole 5 and screwed into the first threaded hole 3 for fixation. When adjusting the left and right position of the base 13, the guide slider 14 is embedded into the guide groove 9 of the support plate 8. After sliding into place, the fixing screw 11 is passed through the through rod port 10 and the screw through hole 15, and the first fixing nut 12 is tightened to lock it. When fixing the pipeline, the pipeline is placed into the first arc-shaped fixing sleeve 16, and the second arc-shaped fixing sleeve 17 is covered and spliced. The friction is increased by the inner anti-slip pad 23. Then, the second fixing bolt 19 is passed through the second threaded hole 18, and the second fixing nut 20 is tightened to complete the fastening, realizing flexible adjustment and stable installation of the pipeline connection.

[0042] 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.
