INFLATING CONNECTOR

An inflating connector (1, 2, 3) of the present invention includes a base (10), a pressure valve (20), a gas bottle connecting seat (30), and a throttling valve (41). The base (10) has an assembling passageway (13), a first gas passageway (14) communicating with the assembling passageway (13), and a second gas passageway (15) communicating with the assembling passageway (13), for a gas nozzle to be connected with the second gas passageway (15). The pressure valve (20) has an elastic member (28) and a piston (24), which are accommodated in the first gas passageway (14). The elastic member (28) acts on the piston (24) to make it close up the first gas passageway (14). The gas bottle connecting seat (30) is disposed on a side of the assembling passageway (13), and has a gas inlet passageway (32) for being connected with a gas bottle (4) and a gas outlet passageway (37) communicating with the gas inlet passageway (32). The throttling valve (41) is disposed on another side of the assembling passageway (13), and has an operation unit (46) and a throttling member (42) capable of being driven by the operation unit (46) to displace along the gas outlet passageway (37). As a result, the inflating connector (1, 2, 3) of the present invention can change the intake gas quantity and intake gas pressure of the gas flowing thereinto from the gas bottle (4).
