[0018] The terms and words used in the following description and claims are not limited to their literal meaning, but are used solely by the person skilled in the art to enable a clear and consistent understanding of this application. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this application is provided for illustrative purposes only and not for the purpose of limiting the application as defined in the appended claims and their equivalents.

[0019] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0020] While ordinal numbers such as "first," "second," etc., will be used to describe various components, there is no limitation on which components are used herein. The term is used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0022] refer to Figures 1 to 2 According to a preferred embodiment of the present invention, an air conditioning liquid inlet pipe with a leak-proof function is provided. It should be noted that the structure of the air conditioning liquid inlet pipe with a leak-proof function is as follows: Figure 1 As shown, it includes a connector 10, a first connecting tube 20, and a plurality of second connecting tubes 30, all of which mate with the connector 10. Specifically, the connector 10 has a first connecting portion 11, an extension portion 12, and a second connecting portion 13. The two ends of the extension portion 12 are respectively connected to the first connecting portion 11 and the second connecting portion 13, and the first connecting portion 11, the extension portion 12, and the second connecting portion 13 are integrally formed, wherein the surface of the extension portion 12 is an arc-shaped structure.

[0023] Furthermore, the end of the first connecting portion 11 opposite to the extension portion 12 also has a plurality of spaced-apart first connecting holes 101. Preferably, there are three first connecting holes 101 arranged in a triangular shape, and for ease of processing, the first connecting holes 101 are straight holes. Specifically, the ends of the plurality of second connecting tubes 30 are connected to the plurality of first connecting holes 101 respectively.

[0024] It should be noted that the end of the second connecting part 13 opposite to the end of the first connecting part 11 also has a second connecting hole 102, and the bottom wall forming the second connecting hole 102 also has an annular groove 103. The ends of the plurality of first connecting holes 101 are all connected to the annular groove 103, and the second connecting hole 102 is also connected to the annular groove 103. It is worth mentioning that the diameter of the annular groove 103 is larger than the diameter of the second connecting hole 102, so as to match the plurality of first connecting holes 101.

[0025] In addition, the sidewall forming the first connecting hole 101 also has an arc-shaped cavity 104. The arc-shaped cavity 104 is movably connected to the end of the first connecting pipe 20. That is, the advantage of this application is that the end of the first connecting pipe 20 that cooperates with the arc-shaped cavity 104 can rotate at a predetermined angle. Previously, the first connecting pipe 20 and the first connecting hole 101 were connected by a threaded connection. This connection method fixed the position of the first connecting pipe 20 and was not flexible enough. The improved first connecting pipe 20 can move at a predetermined angle to facilitate the subsequent cooperation of the first connecting pipe 20 with other components.

[0026] Furthermore, the first connecting pipe 20 includes a pipe body 21 and a ball head member 22. The ball head member 22 is movably disposed in the arc-shaped cavity 104, and one side of the ball head member 22 also has a connecting surface, which is a plane and is placed on the outside.

[0027] Furthermore, the connecting surface also has an assembly hole 2201. One end of the tube body 21 is engaged with the assembly hole 2201, and the other end is configured to engage with an external component. Specifically, the fluid medium enters the assembly hole 2201 through the tube body 21, and sequentially passes through the second connecting hole 102, the annular groove 103, and multiple first connecting holes 101, and enters into multiple first connecting tubes 20. It should be noted that the sidewall forming the first connecting hole 101 is pressed by an external pressing device, causing the wall surface of the second connecting hole 102 to press against the surface of the ball head 22 to form the arc-shaped cavity 104.

[0028] It should also be noted that the wall surface forming the second connecting hole 102 also has an annular mounting groove 105. A sealing ring 40 is provided in the annular mounting groove 105 so that after the arc-shaped cavity 104 is pressed into shape, due to the pressure deformation of the wall surface forming the second connecting hole 102, the sealing ring in the annular mounting groove 105 will press against the surface of the spherical part to ensure the sealing performance of that part. In addition, the tube body 21 and the assembly hole 2201 are connected by threads to limit the position of the tube body 21 to ensure the sealing performance at that point.

[0029] In summary, the air conditioning liquid inlet pipe with anti-leakage function described in the embodiments of this application is explained, which provides advantages such as convenient connection and adjustment, simple structure, and convenient use.

[0030] It is worth mentioning that, in this embodiment, the leak-proof air conditioning liquid inlet pipe has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the leak-proof air conditioning liquid inlet pipe provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0031] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
