Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to an air conditioning copper pipe assembly that can prevent deformation. Background Technology

[0002] Copper pipes in air conditioning systems are core components of the refrigeration cycle system, undertaking four main functions: refrigerant transport, heat conduction, pressure maintenance, and equipment connection. As a key component connecting indoor and outdoor units in an air conditioning system, copper pipes, through their excellent thermal conductivity, pressure resistance, and corrosion resistance, ensure efficient refrigerant circulation, directly affecting the cooling efficiency and service life of the air conditioner.

[0003] Air conditioning copper pipes typically only have an external insulation layer, which is insufficient for protection. Not only is the insulation effect poor, but the protection of the copper pipes is also poor. The copper pipes will deform after being hit, which will lead to damage and affect the use of the pipes. Therefore, we have proposed a deformation-resistant air conditioning copper pipe assembly. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an air conditioner copper pipe assembly that can prevent deformation, so as to solve the problem mentioned in the background art that air conditioner copper pipes generally only have an insulation layer on their outside, which cannot produce sufficient protection. Not only is the heat insulation effect poor, but the protection of the copper pipe is also poor. After being hit, the copper pipe will deform, which will lead to damage to the copper pipe and affect its use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant air conditioning copper pipe assembly, comprising a copper pipe body, an insulation layer fixedly connected to the outer side of the copper pipe body, a heat insulation layer sleeved on the outer side of the insulation layer, a wear-resistant layer fixedly connected to the outer side of the heat insulation layer, an elastic layer fixedly connected to the outer side of the wear-resistant layer, and fixing structures provided at both ends of the copper pipe body. Each fixing structure includes an outer frame, a rotating groove formed inside the outer frame, a sliding groove (first) formed on one side of the outer frame, and a sliding groove (second) formed on the outer surface of the outer frame. The rotating groove is slidably connected inside... A rotating ring is attached, with a pull rod fixedly connected to one end of the rotating ring and a fixing block fixedly connected to the other end of the rotating ring. A buckle is fixedly connected to the surface of the outer frame and the fixing block. A hand-tightening knob is rotatably connected to the top of the rotating ring, and a threaded rod is fixedly connected to the bottom of the hand-tightening knob. A spring is sleeved on the outer side of the threaded rod, and a pressure plate is fixedly connected to the bottom of the threaded rod. A connecting structure is provided on the surface of the fixing structure, including a protective rod. One end of the protective rod is fixedly connected to a threaded protrusion, and three sets of threaded protrusions are fixedly connected to the surface of the outer frame.

[0006] Preferably, both the outer frame and the rotating ring are annular, the pull rod is slidably connected in the first slide groove, and the hand-tightening knob is slidably connected in the second slide groove.

[0007] Preferably, the hand-tightening knob, the threaded rod, the spring, and the pressure plate constitute a set of clamping components. Four sets of clamping components are equidistantly arranged on the rotating ring. A circular groove is formed on the surface of the rotating ring, and a threaded groove is formed at the bottom of the circular groove. The threaded rod is rotatably connected in the circular groove and the threaded groove.

[0008] Preferably, the two ends of the spring are respectively abutted and connected to the bottom of the rotating ring and the top of the pressure plate, and the inner surface of the spring does not contact the surface of the threaded rod.

[0009] Preferably, the pressure plate is arc-shaped, and a rubber pad layer is provided at the bottom of the pressure plate.

[0010] Preferably, the protective rod has a threaded groove 2 at the end away from the threaded protrusion 1, and the outer frame has a threaded groove 3 at the side away from the threaded protrusion 2. Both the threaded protrusion 1 and the threaded protrusion 2 cooperate with the threaded groove 2 and the threaded groove 3.

[0011] Preferably, the protective rod is provided in multiple sets, and the number of threaded protrusions is the same as that of the protective rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This type of deformation-resistant air conditioning copper pipe assembly is equipped with a heat insulation layer, a wear-resistant layer, an elastic layer, a clamping component, and a connecting structure. The heat insulation layer, wear-resistant layer, and elastic layer are fitted over the outside of the heat insulation layer. The heat insulation layer increases the heat insulation performance of the copper pipe body, and the wear-resistant layer increases the wear resistance of the copper pipe body. The two sets of outer frames are connected to each other through the cooperation of threaded protrusion one, threaded protrusion two, threaded groove two, and threaded groove three. The protective rod increases the anti-collision performance of the copper pipe body. After the two sets of fixing structures are installed at both ends of the elastic layer, the threaded rod is rotated by turning the hand-tightening knob. When the thread on the surface of the threaded rod leaves the threaded groove one, the pressure plate is pressed against the surface of the elastic layer under the action of the spring, thereby deforming the elastic layer. In turn, it cooperates with the outer frame to press the elastic layer against the outside of the heat insulation layer, increasing the tightness of the connection between the heat insulation layer, heat insulation layer, wear-resistant layer, and elastic layer. This not only increases the heat insulation performance but also provides better protection, preventing the surface of the copper pipe body from deforming due to lack of cushioning in the event of a collision.

[0014] 2. This type of deformation-resistant air conditioning copper pipe assembly features a fixing structure and a connecting structure. During installation, the elastic layer, which is sleeved on the outside of the insulation layer, is placed on the surface of the outer frame. Pulling the pull rod moves the rotating ring, causing it to rotate out of the rotating groove. The fixing block is then locked to one side of the outer frame using a buckle, forming a complete circle with the rotating ring and the outer frame, thus fixing the copper pipe body inside. When not in use, the rotating ring can be rotated and stored in the rotating groove, reducing the space occupied. The connecting structure facilitates the connection of two sets of fixing structures. The fixing and connecting structures occupy little space, and the modular design makes both easy to install and disassemble. Attached Figure Description

[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 see Figure 1-5 One embodiment provided by this utility model:

[0023] A deformation-resistant air conditioning copper pipe assembly includes a copper pipe body 1. An insulation layer 11 is fixedly connected to the outer side of the copper pipe body 1. A heat insulation layer 12 is sleeved on the outer side of the insulation layer 11. A wear-resistant layer 13 is fixedly connected to the outer side of the heat insulation layer 12. An elastic layer 14 is fixedly connected to the outer side of the wear-resistant layer 13. Fixing structures 2 are provided at both ends of the copper pipe body 1. The fixing structure 2 includes an outer frame 21. A rotating groove 22 is formed inside the outer frame 21. A sliding groove 23 is formed on one side of the outer frame 21. A sliding groove 24 is formed on the outer surface of the outer frame 21. A rotating ring 25 is slidably connected inside the rotating groove 22. A pull rod 26 is fixedly connected to one end of the rotating ring 25, and a fixing block 27 is fixedly connected to the other end of the rotating ring 25. The outer frame 21 and the fixing block 27 are... The surface of the fixed structure 2 is fixedly connected with a buckle 28. The top of the rotating ring 25 is rotatably connected with a hand-tightening knob 29. The bottom of the hand-tightening knob 29 is fixedly connected with a threaded rod 210. A spring 211 is sleeved on the outside of the threaded rod 210. A pressure plate 212 is fixedly connected to the bottom of the threaded rod 210. A connecting structure 3 is provided on the surface of the fixed structure 2. The connecting structure 3 includes a protective rod 31. One end of the protective rod 31 is fixedly connected with a threaded protrusion 32. Three sets of threaded protrusions 33 are fixedly connected to the surface of the outer frame 21. A heat insulation layer 12, a wear-resistant layer 13, an elastic layer 14, a clamping assembly, and a connecting structure 3 are provided. The heat insulation layer 12, the wear-resistant layer 13, and the elastic layer 14 are sleeved on the outside of the heat insulation layer 11. The heat insulation layer 12 increases the heat insulation performance of the copper tube body 1. The wear layer 13 increases the wear resistance of the copper tube body 1. Two sets of outer frames 21 are connected by the cooperation of threaded protrusion 1 32, threaded protrusion 2 33, threaded groove 2, and threaded groove 3. The protective rod 31 increases the anti-collision performance of the copper tube body 1. After the two sets of fixing structures 2 are installed at both ends of the elastic layer 14, the threaded rod 210 is rotated by turning the hand-tightening knob 29. When the thread on the surface of the threaded rod 210 leaves the threaded groove 1, the pressure plate 212 is pressed against the surface of the elastic layer 14 under the action of the spring 211, causing the elastic layer 14 to deform. This, in turn, cooperates with the outer frame 21 to press the elastic layer 14 tightly against the outside of the insulation layer 11, increasing the tightness of the connection between the insulation layer 11, the heat insulation layer 12, the wear-resistant layer 13, and the elastic layer 14, and increasing the insulation... While providing good thermal performance, it also offers good protection, preventing deformation of the copper tube body 1 surface due to lack of cushioning in the event of a collision. A fixing structure 2 and a connecting structure 3 are incorporated. During installation, the elastic layer 14, fitted onto the outside of the insulation layer 11, is placed on the surface of the outer frame 21. Pulling the pull rod 26 moves the rotating ring 25, causing it to rotate out of the rotating groove 22. The fixing block 27 is then locked to one side of the outer frame 21 via a latch 28, forming a complete circle with the rotating ring 25, thus securing the copper tube body 1 inside. When not in use, the rotating ring 25 can be rotated and stored in the rotating groove 22, reducing its space occupation. The connecting structure 3 facilitates the connection of the two fixing structures 2. Both the fixing structure 2 and the connecting structure 3 occupy minimal space.The modular design makes both easy to install and disassemble.

[0024] Furthermore, both the outer frame 21 and the rotating ring 25 are annular. The pull rod 26 is slidably connected in the first slide groove 23, and the hand-tightening knob 29 is slidably connected in the second slide groove 24. The pull rod 26 drives the rotating ring 25 to move, so that the rotating ring 25 rotates out of the rotating groove 22 and forms a complete circle with the outer frame 21, fixing the copper tube body 1 inside it. At the same time, when the rotating ring 25 moves, the pull rod 26 and the hand-tightening knob 29 do not interfere with the outer frame 21 through the first slide groove 23 and the second slide groove 24.

[0025] Furthermore, the hand-tightening knob 29, threaded rod 210, spring 211, and pressure plate 212 constitute a set of clamping components. Four sets of clamping components are equidistantly arranged on the rotating ring 25. A circular groove is opened on the surface of the rotating ring 25, and a threaded groove is opened at the bottom of the circular groove. The threaded rod 210 is rotatably connected in the circular groove and the threaded groove. By turning the hand-tightening knob 29, the threaded rod 210 is rotated. When the thread on the surface of the threaded rod 210 leaves the threaded groove, the pressure plate 212 is pressed against the surface of the elastic layer 14 under the action of the spring 211, thereby deforming the elastic layer 14, and then cooperating with the outer frame 21 to press the elastic layer 14 against the outside of the insulation layer 11.

[0026] Furthermore, the two ends of the spring 211 are respectively connected to the bottom of the rotating ring 25 and the top of the pressure plate 212. The inner surface of the spring 211 does not contact the surface of the threaded rod 210, and the spring 211 will not interfere with the surface of the threaded rod 210 when it deforms.

[0027] Furthermore, the pressure plate 212 is arc-shaped, and a rubber pad layer is provided at the bottom of the pressure plate 212. The pressure plate 212 can be rotated and adjusted by turning the hand-tightening knob 29 so that its surface fits better with the surface of the elastic layer 14.

[0028] Furthermore, the protective rod 31 has a threaded groove 2 at the end away from the threaded protrusion 32, and the outer frame 21 has a threaded groove 3 at the side away from the threaded protrusion 33. The threaded protrusion 32 and the threaded protrusion 33 both cooperate with the threaded groove 2 and the threaded groove 3. The two sets of outer frames 21 are connected to each other through the cooperation of the threaded protrusion 32, the threaded protrusion 33, the threaded groove 2 and the threaded groove 3. The protective rod 31 increases the anti-collision performance of the copper tube body 1. When it is hit, the impact force is transmitted to the outer frame 21 through the protective rod 31. The impact force is absorbed by the elastic layer 14, preventing the copper tube body 1 from being directly impacted and deformed.

[0029] Furthermore, the guard rod 31 is provided with multiple sets, and the number of threaded protrusions 32 is the same as that of the guard rod 31. The specific number of guard rods 31 depends on the spacing between the two sets of fixing structures 2.

[0030] Working principle: During use, based on the length of the copper pipe body 1 to be protected, take out an appropriate length of the insulation layer 12, wear-resistant layer 13, and elastic layer 14, along with an appropriate number of protective rods 31. Sleeve the insulation layer 12, wear-resistant layer 13, and elastic layer 14 onto the outside of the insulation layer 11. Connect the two sets of outer frames 21 through the cooperation of threaded protrusions 32, 33, 2, and 3. Place the elastic layer 14, fitted onto the outside of the insulation layer 11, on the surface of the two sets of outer frames 21. Pull the lever 26 to move the rotating ring 25, causing it to rotate out of the rotating groove 22. Lock the fixing block 27 to one side of the outer frame 21 using the latch 28, so that the rotating ring 25 and the outer frame 21 form a complete circle. Rotate the hand-tightening knob 29 to rotate the threaded rod 210. When the thread on the surface of the threaded rod 210 leaves the threaded groove... Then, under the action of spring 211, pressure plate 212 is pressed against the surface of elastic layer 14, thereby deforming elastic layer 14, and then cooperating with outer frame 21 to press elastic layer 14 against the outside of insulation layer 11, fixing copper tube body 1 inside fixed structure 2. Pulling up the hand-tightening knob 29 can drive pressure plate 212 to move upward. At this time, rotating the hand-tightening knob 29 can rotate and adjust pressure plate 212 to make its surface fit better with the surface of elastic layer 14. When not in use, the rotating ring 25 can be rotated and stored in rotating groove 22. At this time, lifting the hand-tightening knob 29 will drive threaded rod 210 to move upward and rotate into thread groove 1. Through the cooperation of threaded rod 210 and thread groove 1, pressure plate 212 moves upward and fixes its position. At this time, the pull rod 26 can be pulled to drive rotating ring 25 into rotating groove 22, reducing the space occupied by fixed structure 2.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
