Description

Technical Field

[0001] This utility model relates to the technical field of adapters, and in particular to a refrigerant adapter. Background Technology

[0002] In automotive air conditioning systems, the connection between the refrigerant and the air conditioning pipes usually requires the use of adapters to ensure the flow and sealing of refrigerant between the pipes and other components. Most existing adapter designs use end-face sealing to connect to the air conditioning pipes, but this design is not compatible with certain special components (such as filler caps or other connectors). In addition, existing adapters usually use a single sealing method, which may result in insufficient sealing at the connection points, thereby affecting the reliability of the system and increasing design complexity and system cost.

[0003] Therefore, developing a conversion joint that simultaneously possesses radial sealing and end-face sealing functions is of great significance for improving system reliability and reducing production costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a refrigerant adapter that adopts a double-seal design, which can simultaneously meet two different types of sealing requirements and ensure the reliability and sealing performance of the connection parts.

[0005] This utility model discloses a refrigerant adapter, comprising a main body and a fixing component, the fixing component being disposed on the outer side wall of the main body; it also includes a through hole, a radial connecting portion, and an end face. The through hole extends vertically through the interior of the main body, the radial connecting portion is disposed at the bottom end of the main body and its top end communicates with the through hole, and the end face is disposed at the top end of the main body and circumferentially disposed at the top of the through hole. In use, the main body is installed and fixed by the fixing component, and then the top end of the through hole and the radial connecting portion are connected to external equipment respectively. By adopting an end face sealing design at the top end of the main body, when the top end of the through hole is connected to an air conditioning pipe, the top end of the through hole is sealed through end face contact, ensuring efficient sealing when connecting to the air conditioning pipe and reducing leakage caused by poor sealing. By adopting a radial connecting portion sealing design at the bottom end of the main body, reliable sealing is ensured when connected to the charging port. By adopting a dual-seal design, two different types of sealing requirements can be met simultaneously, ensuring the reliability and sealing of the connection parts.

[0006] Preferably, the radial connection includes a tube body, a first O-ring, and a second O-ring. The tube body is installed at the bottom of the main body and communicates with the through hole. The first O-ring is installed on the lower part of the outer wall of the tube body, and the second O-ring is installed on the upper part of the outer wall of the tube body. When the bottom end of the tube body is inserted into an external device for connection and use, the double O-ring design of the first and second O-rings seals the connection, providing a better sealing effect, effectively preventing refrigerant leakage, ensuring the reliability of the air conditioning system, and further improving the operating efficiency of the entire air conditioning system.

[0007] Preferably, it also includes a fixing hole, which is provided on the fastener; by allowing the bolt to pass through the inside of the fixing hole, the convenience of using bolts to fix and install the fastener is improved.

[0008] Preferably, the first O-ring and the second O-ring are Φ8x2.2mm sealing rings; this ensures a good sealing effect while adapting to common sealing ring sizes, making them easy to obtain and replace.

[0009] Preferably, the fixing hole is compatible with bolts of M8 size and below; this facilitates quick and secure connection of the fastener to other system components, simplifying installation and maintenance.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the main body is installed and fixed by the fastener, and then the top of the through hole and the radial connection part are connected to the external equipment respectively. By adopting the end face sealing design at the top of the main body, when the top of the through hole is connected to the air conditioning pipe, the top of the through hole is sealed by end face contact, which ensures the high efficiency of the air conditioning pipe connection and reduces leakage caused by poor sealing. By adopting the radial connection part sealing design at the bottom of the main body, reliable sealing is ensured when connected to the filling port. By adopting the double sealing design, two different types of sealing requirements can be met at the same time, ensuring the reliability and sealing of the connection part.
