[0031] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0032] Please refer to Figures 1 to 5As shown, an embodiment of the present invention provides a high-precision capillary copper tube for air conditioning refrigeration, comprising: a capillary copper tube 1, and a capillary copper tube 2 matching the capillary copper tube 1 at its end, and the capillary copper tube 1 and the capillary copper tube 2 are fixedly connected by a connecting mechanism 3.

[0033] By adopting the above technical solution, not only can the initial connection of capillary copper tube 1 and capillary copper tube 2 be conveniently and initially connected by setting the initial snap-fit ​​component 302, but also the connection of capillary copper tube 1 and capillary copper tube 2 after connection can be firmly achieved by setting the installation and fixing component 303. Therefore, the convenience and stability of the connection between capillary copper tube 1 and capillary copper tube 2 of this utility model are increased. At the same time, the sealing gasket 3011 is set to increase the sealing performance of the connection between capillary copper tube 1 and capillary copper tube 2, thereby improving the practicality of this utility model.

[0034] To increase the ease of connecting capillary copper tube 1 and capillary copper tube 2, the capillary copper tube 1 and capillary copper tube 2 are first initially positioned by the preliminary snap-fit ​​component 302, and then the capillary copper tube 1 and capillary copper tube 2 are stably connected by the installation and fixing component 303, thereby increasing the convenience and stability of the docking of capillary copper tube 1 and capillary copper tube 2. In this utility model, the connecting mechanism 3 includes a sealing connecting seat 301 fixedly connected to the end of capillary copper tube 1. The top and bottom of the sealing connecting seat 301 are both equipped with the preliminary snap-fit ​​component 302 for initially positioning capillary copper tube 2, and the top and bottom of the side of the sealing connecting seat 301 are both equipped with the installation and fixing component 303 for fixing capillary copper tube 2.

[0035] In order to improve the sealing performance when capillary copper tube 1 and capillary copper tube 2 are connected, in this embodiment: a sealing gasket 3011 for sealing capillary copper tube 2 is fixedly connected to the side of the inner wall of the sealing connection seat 301.

[0036] To facilitate the initial positioning of capillary copper tube 1 and capillary copper tube 2, in this embodiment: the initial snap-fit ​​assembly 302 includes an installation groove 3021 formed on the sealing connection seat 301. An installation rod 3022 is fixedly connected to the inner wall of the installation groove 3021. Two symmetrically arranged connecting springs 3023 are fixedly connected to the installation rod 3022. The ends of the two connecting springs 3023 are fixedly connected by a connecting slider 3024. A sliding block 3025 is fixedly connected to the connecting slider 3024. A positioning groove 30251 matching the sliding block 3025 is formed on the capillary copper tube 2 at the position corresponding to the sliding block 3025. A sliding groove 30251 is also formed on the installation rod 3022. A pull rod 3026 is connected to drive the connecting slider 3024, and one end of the pull rod 3026 near the connecting slider 3024 is fixedly connected to the connecting slider 3024. When the capillary copper tube 2 is inserted into the sealing connecting seat 301, it will squeeze the sliding block 3025 and compress the sliding block 3025 into the mounting groove 3021. At the same time, it will compress the connecting spring 3023. When the sliding block 3025 moves to the position of the positioning groove 30251, it can be driven by the elastic force of the connecting spring 3023 to drive the sliding block 3025 into the corresponding positioning groove 30251, thereby achieving the initial positioning of the capillary copper tube 1 and the capillary copper tube 2.

[0037] To increase the ease of pressing the top of the sliding block 3025, in this embodiment, the side of the sliding block 3025 is designed with an arc shape.

[0038] Please refer to Figures 1 to 5 As shown, the mounting and fixing assembly 303 includes a fixing bolt 3031 fixedly connected to the side of the sealing connection seat 301. A fixing lug 3032, which cooperates with the fixing bolt 3031, is fixedly connected to the capillary copper tube 2 at the position corresponding to the fixing bolt 3031. A fixing nut 3033 is threadedly connected to the fixing bolt 3031 at the position corresponding to the fixing lug 3032. When the capillary copper tube 1 and the capillary copper tube 2 are installed together, the fixing bolt 3031 is inserted into the corresponding fixing lug 3032, and then the fixing nut 3033 is tightened to achieve a stable connection between the capillary copper tube 1 and the capillary copper tube 2.

[0039] Please refer to Figures 1 to 5 As shown, both sides of the connecting slider 3024 are fixedly connected with limiting sliders 30241 for limiting the connecting slider 3024. The inner wall of the mounting groove 3021 is provided with a limiting groove 30242 that matches the limiting slider 30241. By setting the limiting slider 30241 and the limiting groove 30242, the connecting slider 3024 is limited, thereby increasing the stability of the connecting slider 3024 driving the sliding block 3025 to be inserted into the positioning slot 30251.

[0040] The working principle of this utility model is as follows: By setting the initial snap-fit ​​component 302, when the capillary copper tube 2 is inserted into the sealing connector 301, it will squeeze the sliding snap-fit ​​block 3025 and compress it into the mounting groove 3021. Simultaneously, it will compress the connecting spring 3023. Furthermore, when the sliding snap-fit ​​block 3025 moves to the position of the positioning slot 30251, under the elastic force of the connecting spring 3023, it will engage with the corresponding positioning slot 30251, thereby enabling the capillary copper tube 1 and the capillary copper tube... The capillary copper tube 1 and capillary copper tube 2 are initially positioned, and by setting the installation and fixing component 303, when the capillary copper tube 1 and capillary copper tube 2 are connected, the fixing bolt 3031 is inserted into the corresponding fixing ear 3032, and then the fixing nut 3033 is tightened, so that the capillary copper tube 1 and capillary copper tube 2 can be stably connected. Therefore, the convenience and stability of the connection between the capillary copper tube 1 and capillary copper tube 2 are increased. At the same time, the sealing gasket 3011 is set to increase the sealing performance of the connection between the capillary copper tube 1 and capillary copper tube 2, thereby improving the practicality of the present invention.
