Novel inflating valve

Abstract

The invention belongs to the field of bicycle components, and particularly relates to a novel inflating valve. The novel inflating valve comprises a hollow valve rod. An upper pressing piece and a lower pressing piece which are connected with a tire body are arranged at the lower end of the valve rod. A thread is arranged on the outer surface of the valve rod. The valve rod is further provided with a positioning nut for positioning the valve rod. A valve core is arranged in the valve rod. The top of the valve rod is further connected with a valve locking cover. The valve core comprises an outer core body and an inner core body. The outer core body is provided with a through hole for flowing of gas. A cavity is formed in the part, at the lower end of the through hole, of the outer core body. The inner core body is arranged in the cavity of the outer core body. A blind hole with the diameter larger than that of the through hole is formed in the position, corresponding to the through hole, of the inner core body. The blind hole is internally provided with a sealing ball and a spring resetting the sealing ball. Air runners communicating with a tire cavity are formed in the two sides of the blind hole. The novel inflating valve solves the problem of air leakage caused by aging of a valve core, and maintenance of people for the inflating valve is reduced.

Description

technical field [0001] The patent of the present invention belongs to the field of bicycle parts, and in particular relates to a novel air valve. Background technique [0002] In existing non-motor vehicle tires, all valves are equipped with valve needles, valve cores and valve compression nuts. When inflating, compressed air passes through the small holes of valve needles and enters the tire, and the valve cores play a role in sealing. When using a non-motorized vehicle, the valve core (rubber hose) is squeezed, rubbed and the temperature inside the tire changes, and the valve core ages faster, causing the tire to leak easily and affecting the user's health. Therefore, aiming at the deficiencies of the prior art, the air valve is improved. Contents of the invention [0003] In order to solve the above technical problems, the patent of the present invention provides a new type of valve, which includes a hollow valve stem. The lower end of the valve stem is provided with a...
