Detailed Description
The present utility model will be described in detail hereinafter with reference to the drawings in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.
In the description of the present innovations, it should be understood that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "bottom," "top," and the like indicate an orientation or positional relationship based on that shown in the drawings, merely to facilitate description of the present innovations and simplify description, rather than to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present innovations.
Referring to fig. 1 and 2, the dual-purpose inflation connector for T-shaped and American-style provided in this embodiment includes an inflation housing 1, a french air tap connector 2, an American air tap connector 8, an American air tap ejector rod 6, and a rubber ball 5, wherein an air intake channel is provided in the inflation housing 1; the French air tap connecting piece 2 is inserted into the inflatable shell 1, the left end is provided with an internal thread connected with the French air tap and an annular groove, the annular groove can accommodate a sealing ring I3 which plays a sealing role when being connected with the French air tap, the right end is provided with a thread, a counter bore and a hemispherical cavity, the cavity is communicated with an air inlet channel of the shell, the French air tap connecting piece 2 is provided with two annular grooves, and the annular grooves are provided with sealing rings II 4; the American type air tap connecting piece 8 is in threaded lock with the right end of the French type air tap connecting piece 2, and the right end of the American type air tap connecting piece 8 is provided with internal threads connected with the American type air tap; the American type air tap ejector rod 6 is inserted into a counter bore at the right end of the French type air tap connecting piece 2, a spherical air chamber 9 is formed between the American type air tap ejector rod 6 and the hemispherical surface at the right end of the French type air tap connecting piece 2, a sealing ring III 7 is arranged on the American type air tap ejector rod 6, an ejector rod with a side wall opening is arranged on the right side, and an air inlet channel is arranged in the middle; the rubber ball 5 is arranged in a spherical air chamber 9 formed by combining the French air tap connecting piece 2 and the American air tap ejector rod 6, and the outer diameter of the rubber ball is slightly smaller than the inner diameter of the spherical air chamber 9.
According to the T-shaped American dual-purpose inflation connector provided by the embodiment, after one end of the French air tap is connected with an object to be inflated, air flows in the American air tap direction preferentially (the air flows in a low-pressure area preferentially, namely, in a small-resistance direction) after entering the air chamber 9 through the air inlet channel of the inflation shell 1, the air pressure difference enables the rubber ball 5 to move towards one end of the American air tap, the air outlet channel at one end of the American air tap is instantaneously blocked by the rubber ball 5, the air changes the flowing direction, flows towards the French air tap and then enters the object to be inflated, the higher the air pressure in the air chamber 9 is, the rubber ball 5 is extruded more tightly, the tightness is better, and one end of the American air tap is connected with the object to be inflated according to the same inflation principle.
