Abstract
The utility model discloses a rubber-plug enclosed valve core. A core body is in the shape of a hollow tube, and a spring and a rubber plug are arranged in the core body. One end of the spring is propped on the air outlet of the core body, and the other end is propped on the air inlet of the core body through the rubber plug. A sealing ring is sheathed at the outside of the core body. When the utility model is used, airflow with pressure forcedly opens the rubber plug to inflate the tyre through the air inlet. When the inflation is finished, the rubber plug props and presses the rubber plug in a conic table of the air inlet through the atmospheric pressure in the tyre and the elastic force of the spring. Therefore, the air can not leak, the sealing performance of the air valve core is improved, and the problem of easy ageing and deterioration of common emulsion tube type air valve cores can be solved. The utility model can be used as a gas nozzle sealing device of inflating tyres of cycles, rickshaws, etc.
Description
The utility model discloses the closed valve inside of a kind of plug, relates to the improvement of pneumatic tire valve core structure.
The conventional bicycle and the wheel valve inside of power car are to adopt emulsion tube to make seal arrangement, lean on gas distending emulsion tube during inflation, make gas enter into inner tube, reach the inflation purpose, because emulsion tube is after use a period of time, easily aged deterioration is followed the string, thereby loses seal action.
For overcoming the shortcoming of latex structure valve inside, the utility model discloses the closed valve inside of a kind of plug.
The utility model is achieved in that core body is a hollow tubular, and device has spring and plug in it, and an end of spring withstands on the air outlet of core body, and the other end withstands on by plug on the air inlet nozzle of core body, and core body is with seal ring outward.
Good effect of the present utility model is: adopt the plug sealing structure unit, reaching under the effect of tire internal air pressure of spring, plug will be pressed on the outlet nozzle tightly, has good sealing effect, reliable working performance, simple in structure, durable, but extensive use bicycle and rickshaw technical field.
Fig. 1 is the utility model structure principle chart.
Further specify the utility model below in conjunction with accompanying drawing: core body 1 is hollow tubular, two ends are respectively equipped with suction port and air outlet, the inwall of suction port is the taper platform, column type plug 5 withstands in the taper platform of suction port, rubber washer 3 is pressed in the inboard, air outlet, the two ends of spring 4 are connected between rubber washer 3 and the plug 5, also are with seal ring 2 at core body 1 outer surface front end; In use, the air-flow that has pressure back down plug 5 by suction port to tyre inflation, when inflation is finished, the elastic force of plug 5 by tire internal air pressure and spring 4 with plug 5 tightly roof pressure in the taper platform of suction port, gas can't be leaked.
