Description

Technical Field

[0001] The utility model relates to a fluorine delivery pipeline assembly. Background Art

[0002] The fluorine delivery pipeline plays an important role in the refrigeration system. It is responsible for the transmission of refrigerant between the compressor and the condenser.

[0003] When the existing fluorine delivery pipeline is fixed, a U-shaped clamp is mostly used; the U-shaped clamp can be placed inside the fluorine delivery pipeline to fix the position of the fluorine delivery pipeline.

[0004] Since the U-shaped clamp fixes the fluorine delivery pipeline in direct contact, there will be a certain gap between the fluorine delivery pipeline and the U-shaped clamp over time or due to thermal expansion and contraction. When used in actual scenarios such as vehicles that need to move, if there is a gap between the fluorine delivery pipeline and the U-shaped clamp, as the main body moves, the fluorine delivery pipeline will collide with the U-shaped clamp, which will cause wear of the fluorine delivery pipeline in the long run.

[0037] Example 1

[0038] A fluorine delivery pipeline assembly comprises a pipe body 1, and the pipe body 1 is used for transmitting refrigerant;

[0039] For fixing the pipe body 1, a common method is to use a U-shaped clamp to fix it, that is, the U-shaped clamp clamps the pipe body 1 and then fixes it to the wall or other installation environment. In actual applications, if the refrigeration equipment is not kept static in the building for a long time, with the combined influence of long-term displacement, thermal expansion and contraction of the fluorine delivery pipeline itself and other factors, a gap is likely to appear between the fluorine delivery pipeline and the U-shaped clamp. The existence of the gap will cause the fluorine delivery pipeline to collide with the U-shaped clamp during the movement of the refrigeration equipment, which will cause wear of the fluorine delivery pipeline in the long run.

[0040] In order to avoid the problem that fixing parts such as U-shaped clamps directly contact the pipe body 1, which would cause a gap between the two and cause them to collide with each other, the fixing method of the pipe body 1 of the fluorine delivery pipeline assembly is improved as follows;

[0041] In this embodiment, a group of fixing units are provided on the surface of the tube body 1;

[0042] The fixing unit comprises a plug-in component 2 and a mounting base 3;

[0043] In this embodiment, one end of the plug-in component 2 is welded to the tube body 1; through the welding connection, the plug-in component 2 and the tube body 1 are integrated, and no gap that can cause a collision between the two is generated;

[0044] One end of the mounting base 3 is provided with a mounting structure 35 for fixing;

[0045] In this embodiment, the mounting structure 35 is a mounting ear, and the mounting ear is provided with a through hole, such as Figure 3 , Figure 5 As shown;

[0046] In this embodiment, the mounting ears are arranged on three sides of the mounting base 3, such as Figure 5 As shown;

[0047] The mounting base 3 can be installed and fixed in the installation environment by screws passing through the holes on the surface of the mounting ears;

[0048] The plug-in component 2 can be fixed to the installation base 3 in cooperation, so as to achieve the fixation of the pipe body 1 relative to the installation environment;

[0049] After the plug-in component 2 is plugged into the mounting base 3 and fixed, a sufficient distance is left between the mounting base 3 and the pipe body 1 to avoid contact and collision between the mounting base 3 and the pipe body 1 .

[0050] Specifically, a mounting hole 31 is formed at one end of the mounting base 3 close to the plug-in component 2 along the axial direction, and the diameter of the mounting hole 31 is adapted to the plug-in component 2;

[0051] The plug-in component 2 can be inserted into the mounting hole 31;

[0052] The mounting base 3 is provided with a limiting mechanism, which is used to lock the plug-in component 3 inserted into the mounting hole 31;

[0053] In this embodiment, the limiting mechanism includes a screw hole 5 opened on the side wall of the mounting base 3. Figure 3 , Figure 4 As shown;

[0054] In this embodiment, the screw holes 5 are formed on the side walls of the mounting base 3. The screw holes 5 are located at one end of the mounting base 3 close to the plug-in component 2. Figure 3 As shown;

[0055] A limiting rod 6 can pass through the screw hole 5 and cooperate with the plug-in component 2 inserted into the mounting hole 31 to achieve locking;

[0056] One end of the limiting rod 6 is connected to a screw rod 61. Figure 7 As shown;

[0057] The screw rod 61 cooperates with the screw hole 5, and the axial position of the limit rod 6 can be locked by the threaded cooperation between the screw rod 61 and the screw hole 5;

[0058] The diameter of the screw rod 61 is larger than the limiting rod 6;

[0059] One end of the screw rod 61 is connected to a nut 62, the diameter of the nut 62 is larger than the screw rod 61, and the circumference of the nut 62 is formed with an anti-slip pattern 63, such as Figure 7 As shown; the user can operate the nut 62 to screw the screw 61 into the screw hole 5;

[0060] In this embodiment, the locking method of the limiting rod 6 and the plug-in component 2 is that after the limiting rod 6 is inserted into the mounting hole 31 through the screw hole 5, its end directly abuts against the outer wall of the plug-in component 2 to achieve locking.

[0061] In this embodiment, a spline structure 21 is formed at the end of the plug-in component 2. Figure 2 As shown;

[0062] The spline structure 21 is integrally formed with the plug-in component 2;

[0063] The mounting base 3 is provided with a keyway 32 adapted to the spline structure 21. Figure 3 , Figure 5 As shown;

[0064] The key slot 32 and the mounting hole 31 are connected to each other. Figure 3 , Figure 5 As shown;

[0065] The spline structure 21 is only provided at the front end of the plug-in component 2. Figure 2 As shown;

[0066] The spline structure 21 is inserted into the keyway 32 to form a radial limit between the plug-in component 2 and the mounting base 3 .

[0067] In this embodiment, a spring 4 is provided in the mounting base 3;

[0068] The spring 4 is fixedly connected to the mounting base 3 and is located between the mounting base 3 and the plug-in component 2;

[0069] The spring 4 acts between the inner wall of the mounting base 3 and the plug-in component 2, and can achieve a vibration reduction effect between the two.

[0070] This can avoid the problem that after a gap is formed between the end of the plug-in component 2 and the inner wall of the mounting base 3 at the opposite end, the plug-in component 2 will come into hard contact with the inner wall of the mounting base 3 when moving in the mounting hole 31;

[0071] Specifically, the spring 4 is disposed in the keyway 32, as shown in FIG. Figure 6 As shown;

[0072] In this embodiment, the diameter of the spring 4 and the key slot 32 are in transitional fit, which can prevent the spring 4 from falling out of the key slot 32 .

[0073] In this embodiment, a limiting hole 22 is axially formed at one end of the plug-in component 2 close to the mounting base 3. Figure 2 As shown;

[0074] The mounting base 3 is provided with a positioning column 33 adapted to the fish limiting hole 22. Figure 3 As shown;

[0075] After the plug-in component 2 is inserted into the mounting hole 31 , the positioning column 33 will be correspondingly inserted into the limiting hole 22 . The limiting hole 22 and the positioning column 33 cooperate to form a limit between the plug-in component 2 and the mounting base 3 .

[0076] In this embodiment, recesses 34 are provided on both sides of the mounting base 3. Figure 3 As shown, the recesses 34 are symmetrically formed on both sides of the mounting base 3, which can facilitate the user to grasp.

[0077] Example 2

[0078] This embodiment is different from the embodiment 1 in that, in this embodiment, two groups of fixing units are provided on the surface of the tube body 1 .

[0079] In this embodiment, the plug-in component 2 and the tube body 1 are formed integrally.

[0080] In this embodiment, the mounting ears are arranged on four sides of the mounting base 3 .

[0081] In this embodiment, the screw holes 5 are opened on the four side walls of the mounting base 3, and each side wall of the mounting base 3 is provided with a plurality of screw holes 5. Figure 3 , Figure 4 As shown;

[0082] The plurality of screw holes 5 on each side wall are arranged linearly, such as Figure 4 As shown;

[0083] A translation slot 51 is formed between the linearly arranged screw holes 5. Figure 4 As shown;

[0084] In this embodiment, the locking method of the limiting rod 6 and the plug-in component 2 is that the limiting rod 6 and the spline structure 21 are matched and limited near one end of the tube body 1;

[0085] During actual use, after the plug-in component 2 is inserted into the mounting hole 31, since the depth of the mounting hole 31 is greater than the length of the spline structure 21, the spline structure 21 will be immersed in the mounting hole 31; according to the position of the spline structure 21 in the mounting hole 21, the limiting rod 6 is inserted into the corresponding screw hole 5 and cooperates with one end of the spline structure 21 to achieve the limiting fixation of the plug-in component 2; after the limiting rod 6 is inserted into the screw hole 5, the screw 61 is tightened with the screw hole 5 by rotating the operating nut 62 to achieve axial locking of the limiting rod 6.

[0086] In this embodiment, a flange is formed at the boundary between the key slot 32 and the mounting hole 31 , and the flange is used to limit the spring 4 in the key slot 32 to prevent the spring 4 from escaping from the key slot 32 into the mounting hole 31 .

[0087] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to achieve basically the same technical effects are all included in the protection scope of the present invention.
