[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0022] See also Figures 1 to 5As shown, according to an embodiment of the present invention, a pipeline fixing device is provided, the pipeline fixing device comprises a main body 10 and a fixing member 20, the main body 10 is used to be installed on a supporting structure, a first limiting groove 11 and a mounting opening 12 are provided on the main body 10, the first limiting groove 11 is used to be adapted to the first limiting groove 11 of the pipeline 30, the mounting opening 12 is communicated with the first limiting groove 11, and the mounting opening 12 is used to guide the pipeline 30 to be clamped into the first limiting groove 11. The fixing member 20 is detachably connected to the main body 10, and a second limiting groove 21 is provided on the fixing member 20, and the second limiting groove 21 cooperates with the first limiting groove 11 to fix the pipeline 30.

[0023] Combination Figure 1 and Figure 2 The structure of the pipeline fixing device is installed on the pipeline with large force or stress concentration, so as to reduce the deformation of the pipeline. The main body 10 is fixed to the supporting structure (such as the heat exchanger) to ensure the stability of the overall device; the main body 10 is designed with an installation opening 12. During installation, the pipeline can smoothly enter the first limiting groove 11 from the installation opening, so that the main body 10 is tightly fixed to the pipeline to be fixed, and then the fixing member 20 is connected to the main body 10. The first limiting groove 11 and the second limiting groove 21 cooperate to completely fix the pipeline, and finally reduce the external force transmitted to the pipeline to be protected, and prevent the pipeline from fatigue fracture due to stress concentration.

[0024] Combination Figure 3 As shown, the main body 10 includes a base 13 and a protruding structure 14, and the base 13 is formed with a mounting opening 12; the protruding structure 14 is connected to the base 13, and the protruding structure 14 protrudes from the surface of the base 13, and a first limiting groove 11 is formed on the protruding structure 14. The base 13 mainly plays a supporting and stress absorbing role, and can ensure the overall stability of the pipeline fixing device. The protruding structure 14 forms the first limiting groove 11. It can be seen that the mounting opening 12 forms an avoidance space, which allows the pipeline to fit with the protruding structure 14 and be stuck in the first limiting groove 11 after passing through the mounting opening 12. The inner diameter of the first limiting groove 11 is smaller than the inner diameter of the mounting opening 12, and the inner diameter of the mounting opening 12 is larger than the outer diameter of the pipeline, so as to facilitate the installation and insertion of the pipeline.

[0025] Preferably, the protruding structure 14 includes an arc plate 141 and a positioning plate 142, wherein the arc plate 141 forms the first limiting groove 11; the positioning plate 142 is connected to the arc plate 141, and the positioning plate 142 is engaged with the fixing member 20, and the fixing member 20 is fixed to the base 13 by being engaged with the positioning plate 142. In this embodiment, there are two positioning plates 142, and the two positioning plates 142 are respectively located at both ends of the arc plate 141. The relative angle and position of the two positioning plates 142 can be determined according to the position between the surrounding pipelines, with the principle of not interfering with the surrounding pipeline structure.

[0026] See also Figure 4 and Figure 5 The fixing member 20 has a positioning groove 22, which is adapted to the positioning plate 142, and the fixing member 20 is clamped on the positioning plate 142 through the positioning groove 22. The shape of the positioning groove 22 can match the shape and position of the positioning plate 142. The positioning groove 22 can not only be used for positioning, but also mainly plays a role in positioning and fixing. The positioning groove 22 and the positioning plate 142 form an interference fit after the clamping fit, so that the fixing member 20 can press the pipeline after being installed, thereby playing a role in fixing the pipeline.

[0027] In this embodiment, in order to match the positioning plate 142 with two strip plate structures, the positioning groove 22 on the fixing member 20 is in the shape of a strip groove, and the cross section of the strip groove is U-shaped. The fixing member 20 includes two side wall plates 23 arranged opposite to each other, and the two side wall plates 23 arranged opposite to each other form the positioning groove 22. The two side wall plates 23 form one positioning groove 22. If there are multiple positioning grooves 22, the two side wall plates arranged opposite to each other are a group, and multiple groups are provided to form multiple positioning grooves.

[0028] For easy assembly, at least one of the two side wall plates 23 has a guide bending edge, which is bent toward the outside of the positioning groove 22. The guide bending edge mainly guides the positioning plate 142 to slide into the positioning groove 22 to facilitate the clamping of the fixing member 20.

[0029] The base 13 has a bottom plate 15, and the bottom plate 15 is provided with a mounting hole 151. The mounting hole 151 can be a screw hole, and the design of the mounting hole 151 can ensure that the base 13 and the bottom plate 15 can be completely attached to the unit sheet metal or the heat exchanger.

[0030] The base 13 is a hollow columnar structure. The size of the base 13 should be able to accommodate the maximum outer edge size of the pipeline. The hollow columnar structure of the base 13 can reduce the weight and quality of the pipeline fixture, reduce production costs, and facilitate installation.

[0031] The technical effect of this embodiment is as follows: two mounting holes 151 are designed on the base 13, and the base 13 can be fixed to the heat exchanger with screws to ensure the overall stability of the device. The base 13 is a hollow columnar structure and is designed with a mounting opening 12. During installation, the pipeline can smoothly enter the cavity from the mounting opening, and the first limiting groove 11 on the raised structure 14 is tightly fixed to the pipeline that needs to be fixed. Then the positioning groove 22 of the fixing part is inserted into the positioning plate 142 to completely fix the pipeline, and finally the device reduces the external force transmitted to the pipeline that needs to be protected in the unit, preventing the pipeline from fatigue fracture due to stress concentration.

[0032] See also Figure 6The present invention also provides an embodiment of an air conditioner outdoor unit, including the pipeline fixing device of the above embodiment, wherein the supporting structure is a heat exchanger, and the pipeline 30 is a copper tube of the heat exchanger. The pipeline fixing device includes a main body 10 and a fixing member 20. The main body 10 is used to be installed on the supporting structure. The main body 10 is provided with a first limiting groove and an installation opening. The first limiting groove is used to match the first limiting groove of the pipeline 30. The installation opening is connected to the first limiting groove. The installation opening is used to guide the pipeline 30 to be inserted into the first limiting groove. The fixing member 20 is detachably connected to the main body 10. The fixing member 20 is provided with a second limiting groove. The second limiting groove cooperates with the first limiting groove to fix the pipeline 30.
