Abstract

The invention provides a gas terminal and a connecting device thereof. The connecting device comprises a pedestal (1) with a cavity, a spring (2) sleeved on the first end of the pedestal (1), a first chute (11) and a second chute (12) sequentially formed in the pedestal from the first end of the pedestal to the second end, and a first roller pin (51) and a second roller pin (52) respectively arranged in the first chute (11) and the second chute (12); and the first chute (11) and the axis of the pedestal (1) form a first acute included angle alpha, and the second chute (12) and the axis of thepedestal (1) form a second acute included angle beta, wherein alpha is smaller than beta. The connecting device has simple structure and is convenient to use, and automatic unlocking can be realized when a plug is in a pre-insertion state.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a gas terminal and a connection device thereof. Background technique [0002] At present, there are mainly two ways to connect the connection device and the plug of the gas terminal. The first connection device adopts the method of ball and ball cage to cooperate with the plug; the second connection device adopts the method of needle roller and needle groove to cooperate with the plug. During the operation of these two connection devices, it is necessary to press the button to unlock the device and enter the pre-inserted state (the plug is connected to the connection device of the gas terminal, but the gas is not connected), and then the button can be pressed again Disconnect the plug from the gas terminal. [0003] In actual use, the pre-inserted state of the plug is normal, but the connection device cannot be automatically unlocked and the plug cannot be automatically separat...
