Problems solved by technology
[0002] At present, the indoor unit and the outdoor unit of the split type air conditioner in refrigeration products are connected through a stop valve. The requirement of this connection method for the indoor unit and the outdoor unit is that the refrigerant cannot be stored at the same time. The refrigerant and the indoor unit do not store refrigerant, so the indoor unit must be emptied first during installation, and then the refrigerant circulation between the indoor and outdoor units is connected through the shut-off valve. It is difficult to ensure the purity of the refrigerant in the system after the two machines are connected, and the discharged refrigerant pollutes the environment and wastes energy. Therefore, the applicant of this case has applied for utility model patents with application numbers 200420082664.9 and 200420082665.3, which solves the problem of indoor units, There is a problem with the connection of the outdoor unit storing refrigerant at the same time. However, since the indoor unit and the outdoor unit of the split air conditioner are connected by a high-pressure pipe connection and a low-pressure pipe connection, the complexity of the installation process and the installation efficiency cannot be avoided if the two pipes are connected separately twice. Also very low, higher technical requirements for installers

Embodiment Construction
[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] As shown in Figures 1 to 11, the double buckle-type self-locking quick connector includes a jacket 12 respectively connected to the indoor unit and the outdoor unit and a fixing seat 18 fixed on the outdoor unit. Linked connection mechanism. This mechanism is provided with a pair of female connectors 14 connected to the high-pressure pipe of the indoor unit and the female connector 28 of the low-pressure pipe of the indoor unit in the outer jacket. A spring 25 is provided between the plate and the jacket, so that the supporting plate returns to the initial position under the action of the spring preload, and a pair of female connectors 14, 28 are respectively threaded with a pair of pipe joints 23, and the connecting parts are marked with "O" Type sealing ring 13 seals. A pair of copper pipes 1 connected to the high-pressure pipe of the outdo...

The duplex expansion buckle type self locking quick connector is one communication mechanism set in an outer sleeve and one fixed seat. The mechanism includes one pair of mother connecting heads and one pair of unions for connecting indoor unit high and low pressure pipes with inside push rod, one retaining ring positioned tray and spring; and one pair of copper pipes and one pair of unions for connecting indoor unit high and low pressure pipes with valve core. The mechanism is set on rocker spanner mechanism to realize the connection between the indoor and outdoor units and has ball or pin locking mechanism for locking. It may be connected fast and reliable.
Description
technical field [0001] The invention relates to a quick-connect joint for the indoor unit and outdoor unit of a split-type air conditioner for refrigeration products, especially a joint that connects the indoor unit and outdoor unit that simultaneously store the working medium and can be disassembled and connected multiple times and can ensure that the refrigerant does not leak connector. Background technique [0002] At present, the indoor unit and the outdoor unit of the split type air conditioner in refrigeration products are connected through a stop valve. The requirement of this connection method for the indoor unit and the outdoor unit is that the refrigerant cannot be stored at the same time. The refrigerant and the indoor unit do not store refrigerant, so the indoor unit must be emptied first during installation, and then the refrigerant circulation between the indoor and outdoor units is connected through the shut-off valve. It is difficult to ensure the purity of ...
