Document Type and Number:
WIPO Patent Application WO/2018/214811
Kind Code:
A1
Abstract:
A tire inflation rapid fastening head, comprising an air inlet connector (100), an air inlet fastening head (200), a first control member (300), and an elastic member (400). The air inlet fastening head (200) comprises a body (210) and a holding member (220). The body (210) has a first end and a second end and comprises a channel (211) and at least one slit (212). The channel (211) axially runs through the body (210). A middle portion of the slit (212) is in communication with the channel (211). The holding member (220) is accommodated in the slit (212) and is reciprocally movable along the slit (212). Two ends of the holding member (220) protrude from the slit (212). A middle portion of the holding member (220) extends into the channel (211) and engages with an external thread (710) of a tire valve (700). The first control member (300) is movably disposed at the air inlet fastening head (200), and is provided with an accommodation slot (310A, 310B, 310C) used for accommodating the two ends of the holding member (220). When the first control member (300) moves along an axial direction of the air inlet fastening head (200), the position of the holding member (220) in the slit (212) can be changed. One end of the elastic member (400) abuts one end of the first control member (300), and the other end of the elastic member (400) abuts the air inlet connector (100). The tire inflation rapid fastening head enables rapid connection, requires less effort in operation, and achieves good air tightness.
