Abstract
The utility model discloses an air inflating valve, wherein, an air inflating valve body is taken as a cylinder; a piston is arranged in the cylinder; a restoring spring is arranged between the piston and the air inflating valve body; the lower end of the piston is connected with a thimble into integration; the piston and the thimble are hollow and communicated; the lower end of the thimble is sealed; the side wall of the thimble is provided with a small hole; the position of the air inflating valve body, which corresponds to the small hole, is provided with a sealing ring; the inner diameter of the sealing ring is matched with the outer diameter of the thimble. The utility model can effectively prevent the problem that when the inflator is used for inflating by hands, the compressed air in the tyre is leaked.
Description
The utility model and a kind of inflating are chewed, and relating in particular to manual pump is that gas filed the inflating of self-propelled vehicle such as motor bike are chewed.
Existing manual pump can not be chewed just passable but will load onto special inflating directly for the motor bike inflation.This inflate to chew normally chew body by inflating, be installed in and inflate inlet suction port and the air outlet adapter of chewing the body two ends and constituted.Wherein be installed with a thimble on the air outlet adapter.This air outlet adapter chewed of inflating is that to be screwed in wheel laterostigmatal, because the thimble on the air outlet adapter has been depressed laterostigmatal thimble, so the gas in the wheel leaks when spinning, and same, when screwing off air outlet adapter, the gas in the wheel also leaks.
The purpose of this utility model provides a kind of inflating and chews, and it can be avoided when spinning or screw off air outlet adapter, the escape of air in the wheel.
The purpose of this utility model is achieved in that a kind of inflating chew, it includes inlet suction port and air outlet adapter, inflate and chew body as a cylinder, a piston is equipped with in its inside, piston and inflate to chew retracing spring is installed between the body, the lower end of piston and a thimble connect one, and piston is that hollow communicates with thimble.The thimble lower end is a leak free, have the aperture of giving vent to anger in its side-walls, with this aperture position corresponding position, inflate to chew seal ring is installed on the body, the internal diameter of seal ring should match with the external diameter of thimble, feasible seal ring just often just in time seals the aperture on the thimble, moves downward when piston is subjected to gas pressure, and seal ring just can not seal the aperture on the thimble.
The description in a step when the utility model being done below in conjunction with accompanying drawing:
Accompanying drawing is a structural representation of the present utility model.
With reference to the accompanying drawings, inflate and chew body (1) as a cylinder, piston (2) is equipped with in its inside, the lower end of piston (2) and thimble (4) fuse, piston (2) and inflating is chewed between the body bottom a retracing spring (8), an aperture (3) is arranged on the piston (2), and it communicates with gas passage (6) on the thimble (4).The bottom of thimble (4) is a leak free, on its sidewall, have the aperture (7) that communicates with gas passage (6), seal ring (5) is installed inflating the bottom of chewing body (1), the internal diameter of seal ring (5) matches with the external diameter of thimble (4), makes seal ring (5) when not inflating just seal the aperture (7) on the thimble (4).
During use, air outlet adapter is screwed on the valve of wheel, because thimble this moment (4) is not oppressed laterostigmatal thimble, so the gas in the tire can not leak.During inflation, piston (2) moves downward under gas pressure, this moment thimble (4) will oppress laterostigmatal thimble, thimble (4) aperture (7) leave seal ring (5), pressurized air can enter in the tire.When the push rod of mentioning manual pump, because the effect of retracing spring (8) resets piston (2), thimble this moment (4) is no longer oppressed laterostigmatal thimble, pressurized air in the tire can not leaked yet, and the aperture (7) on the thimble (4) is also sealed by seal ring (5).
The utility model is simple in structure, has prevented from effectively spinning or screwing off the problem that the tire compressed air that occurred when chewing air outlet adapter leaks of inflating.
Claims (1)
1. inflate and chew for one kind, comprise inlet suction port and air outlet adapter, it is characterized in that inflating chewing body as a cylinder, a piston is equipped with in its inside, piston and inflate to chew retracing spring is housed between the body, piston lower end and a thimble fuse, and piston and thimble are that hollow communicates, and the thimble lower end is a leak free, have aperture in its side-walls, with this aperture position corresponding position, to inflate to chew seal ring is installed on the body, the internal diameter of seal ring should match with the external diameter of thimble.
