[0001] The invention relates to the technical field of pipelines, in particular to a pipeline fixing component and an air conditioning unit. Background Art

[0002] In the air-conditioning system, the refrigerant is equivalent to the blood of the air-conditioning unit. The rupture of the pipeline will directly affect the normal operation of the unit, causing the air conditioner to lose its most basic air temperature regulation function.

[0003] Air conditioning units generally use pipelines to transport refrigerants. During production, transportation, and operation, the pipelines may be damaged or destroyed. During operation, the vibrations generated by the movement of the moving parts of the unit (compressor, fan blades, etc.) may cause fatigue damage to the pipelines over time, and eventually rupture, causing refrigerant leakage. Or due to the harsh transportation environment, during the transportation of the air conditioner, the pipelines collide with other adjacent structural parts, causing pipeline ruptures and refrigerant leakage.

[0004] The reasons for the above problems are that the pipelines are not effectively fixed. In the prior art, a fixing block is generally used to fix two adjacent pipelines. However, for pipelines in different positions or pipelines in different units, the distance between the two pipelines is not equal. Therefore, it is necessary to design fixing blocks of different sizes for fixing. In actual use, installers are also required to select and use them, which increases design costs and production costs and low production efficiency. Summary of the invention

[0035] In the prior art, a fixing block is generally used to fix two adjacent pipelines. However, for pipelines in different positions or pipelines in different units, the spacing between the two pipelines is not equal. Therefore, it is necessary to design fixing blocks of different sizes for fixing. In actual use, the installer also needs to select the type for use, resulting in increased design and production costs and low production efficiency. Figures 1 to 8 The pipeline fixing assembly shown includes: a fixing block male head 1, which is arranged on the first pipeline, and a first mounting groove 11 is formed on the side wall of the fixing block male head 1; a fixing block female head 2, which is arranged on the second pipeline 20, and a second mounting groove 21 is formed on the side wall of the fixing block female head 2; a fixing block insert 3, which is arranged between the fixing block male head 1 and the fixing block female head 2, and a through groove 33 is provided on the fixing block insert 3, and the first mounting groove 11, the through groove 33 and the second mounting groove 21 are connected end to end to form an annular wire binding groove. The fixing block insert 3 is used to adjust the distance between the fixing block male head 1 and the fixing block female head 2, so that the pipeline fixing assembly can adapt to different pipeline spacings, reduce the design cost of the fixing block, and also reduce the selection and operation difficulty of the installer, thereby improving production efficiency. In addition, the first installation groove 11, the through groove 33 and the second installation groove 21 are used to form a wire tie groove for installing wire ties. The fixing block male head 1, the fixing block female head 2 and the fixing block insert 3 therebetween are fastened and connected by the wire tie, thereby improving the structural reliability of the pipeline fixing assembly, and also improving the fixing effect of the pipeline, reducing the stress rupture and collision rupture problems of the pipeline during operation and transportation, and improving the reliability of the air-conditioning unit.

[0036] There are at least two types of the fixing block inserts 3, and the widths of any two of the fixing block inserts 3 are different. Fixing blocks of different widths are used to fill between the fixing block male head 1 and the fixing block female head 2, so as to adjust the spacing between the fixing block male head 1 and the fixing block female head 2, so that the center distance between the fixing block male head 1 and the fixing block female head 2 can adapt to the spacing between different first pipelines and the second pipeline 20, reduce the design cost of the fixing block, and also reduce the selection and operation difficulty of the installer, thereby improving production efficiency. Specifically, when fixing the first pipeline and the second pipeline 20, the center distance between the first pipeline and the second pipeline 20 is determined, and different fixing block inserts 3 or different numbers of fixing block inserts 3 are selected for installation according to the center distance, and then the fixing block male head 1 is fixed on the first pipeline, and the fixing block female head 2 is fixed on the second pipeline 20, and the selected fixing block inserts 3 are stacked and placed between the fixing block male head 1 and the fixing block female head 2, and then tied in the wire tie groove with a cable tie, so as to complete the fixed connection between the first pipeline and the second pipeline 20.

[0037] For example, the distance from the edge of the fixed block male head 1 to the center of the axis of the first pipeline is set to G, the distance from the edge of the fixed block female head 2 to the center of the axis of the second pipeline 20 is set to M, and the widths of the fixed block insert 3 are set to L1 and L2 respectively to obtain the center distance L between the first pipeline and the second pipeline 20, so that the required width of the fixed block insert 3 can be obtained as LGM, and then according to this width and L1 and / or L2, all L1 fixed block inserts 3 can be selected for use, that is, L=G+M+nL1 at this time; or a part of L1 fixed block inserts 3 and a part of L2 fixed block inserts 3 can be selected for use, that is, L=G+M+aL1+bL2 at this time.

[0038] The fixing block insert 3 includes a first side surface 31 and a second side surface 32 which are arranged opposite to each other along the width direction of the fixing block insert 3, and the first side surface 31 can be abutted with the fixing block male head 1 or the second side surface 32 of the adjacent fixing block insert 3, and the second side surface 32 can be abutted with the fixing block female head 2 or the first side surface 31 of the adjacent fixing block insert 3. The first side surface 31 is abutted with the fixing block male head 1 or the second side surface 32 to ensure that the fixing block insert 3 is in surface contact with the fixing block male head 1 or the adjacent fixing block insert 3, thereby improving the structural reliability of the pipeline fixing assembly. Similarly, the second side surface 32 is abutted with the fixing block female head 2 or the first side surface 31 to ensure that the fixing block insert 3 is in surface contact with the fixing block female head 2 or the adjacent fixing block insert 3, thereby improving the structural reliability of the pipeline fixing assembly.

[0039] A first limiting structure 41 is provided on the fixing block male head 1 and the second side surface 32, and a second limiting structure 42 is provided on the fixing block female head 2 and the first side surface 31, and the first limiting structure 41 can cooperate with the second limiting structure 42 to further avoid relative sliding between the fixing block male head 1 and the fixing block insert 3, and between the fixing block female head 2 and the fixing block insert 3 through the limiting cooperation of the first limiting structure 41 and the second limiting structure 42, thereby further improving the structural reliability of the pipeline fixing assembly.

[0040] As an embodiment, a protrusion is formed on the fixing block male head 1 and the second side surface 32, and the protrusion constitutes the first limiting structure 41. A recess is formed on the fixing block female head 2 and the first side surface 31, and the recess constitutes the second limiting structure 42. During installation, the corresponding protrusion and recess are butted and matched, so as to achieve reliable limiting between the fixing block male head 1 and the fixing block insert 3, and between the fixing block female head 2 and the fixing block insert 3.

[0041] The fixing block insert 3 also includes a third side surface and a fourth side surface that are relatively arranged along the length direction of the fixing block insert 3. The third side surface and the fourth side surface are both provided with the through groove 33. The first installation groove 11, the through groove 33 on the third side surface, the second installation groove 21 and the through groove 33 on the fourth side surface are connected end to end to form the wire tie groove. At this time, the wire tie groove can form an annular groove, so that the wire tie tied to the pipeline fixing assembly can be fully accommodated to prevent the wire tie from being separated, thereby improving the structural reliability of the pipeline fixing assembly.

[0042] The fixing block male head 1 is provided with a first fixing hole 12, and the fixing block male head 1 is provided with a first bayonet 13, and the first pipeline can enter or escape from the first fixing hole 12 through the first bayonet 13. When the first pipeline is installed, the first bayonet 13 is deformed to facilitate the first pipeline to enter the first fixing hole 12, thereby completing the connection between the fixing block male head 1 and the first pipeline.

[0043] The fixing block female head 2 is provided with a second fixing hole 22, and the fixing block male head 1 is provided with a second bayonet 23, and the second pipeline 20 can enter or escape from the second fixing hole 22 through the second bayonet 23. When the second pipeline 20 is installed, the second bayonet 23 is deformed, so that the second pipeline 20 can enter the second fixing hole 22 easily, and the connection between the fixing block female head 2 and the second pipeline 20 is completed.

[0044] The material of the fixing block male head 1 is rubber, and the rubber material is used to further absorb the vibration transmitted to the pipeline, and the softness of the rubber material can also be used to facilitate the deformation of the first bayonet 13.

[0045] The material of the fixing block female head 2 is rubber. The rubber material can be used to further absorb the vibration transmitted to the pipeline, and the softness of the rubber material can also be used to facilitate the deformation of the second bayonet 23.

[0046] An air conditioning unit comprises the above-mentioned pipeline fixing assembly.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
