AIR CONDITIONING COOLANT FORWARDING HOSE CONNECTING DEVICE

摘要

The present invention relates to an air conditioning coolant forwarding hose connecting device, wherein a coolant forwarding hose for supplying air conditioning coolant and an integrated type of air conditioning pipe can be simply and easily connected together and coupled in a hermetically sealed state via a fastening piece, and, while connecting the coolant forwarding hose, a coupling part vacuum state due to a recessed part of a hose connecting piece is maintained, not only such that is it possible to further improve the hermetic sealing properties of the coolant forwarding hose but also such that it is possible to prevent external shocks or the like from causing collapse and damage of the hose connecting piece to which the coolant forwarding hose is connected, and such that it is possible to markedly reduce the vibrations and the like which occur during forwarding of the coolant.
