Abstract
The utility model belongs to the improvement of bicycle inner tube of a tyre inflating valve, especially bicycle inner tube of a tyre flat seal inflating valve, including valve core seat, valve core and rubber tube, the lower extreme that has the valve core that the disc kept off the shoulder is cylindric, and the venthole setting is on cylindrical lateral wall, and the rubber tube suit is kept off on shoulder lower extreme cylinder wall at the valve core, and the drum of valve core seat for having the flange is installing flat rubber pad on the valve core seat mouth, and the fender shoulder of valve core cooperatees with the flat rubber pad on the valve seat mouth, compresses tightly the cooperation with it through the nut. The valve nozzle has good sealing performance, the flat rubber pad is not easy to be broken by extrusion, the service life is long, the valve core has good sealing performance, slow air leakage is effectively prevented, the manufacturing is easy, and the cost is low.
Description
The utility model belongs to the flat envelope of the improvement of bicycle inner tube valve cock, particularly bicycle inner tube valve cock.
Present bicycle inner tube valve cock is that the circular cone in the valve core print seat matches with the conical section of the valve inside that is with rubber pipe, be screwed on the valve core print seat with nut, the conical section of valve inside of rubber pipe and the circular cone compression fit in the valve core print seat will be with, make the hermetic seal in the inner tube of a tyre, it is broken that but the rubber pipe of the conical section of valve inside is squeezed easily, cause deflation, in addition, the rubber pipe of installing on valve inside is because the tightening force deficiency, can not seal the pore of valve inside effectively, and usually cause valve inside to leak slowly.
The purpose of this utility model is to provide the flat envelope of a kind of bicycle inner tube valve cock, can avoid the rubber pipe of the conical section of valve inside to be squeezed broken phenomenon easily, can seal the air outlet hole of valve inside again effectively, prevents that valve inside from leaking.
The utility model is achieved in that the flat envelope of a kind of bicycle inner tube valve cock, comprise the valve core print seat, valve inside and the rubber pipe that is sleeved on the valve inside, the lower end that has the valve inside of disc shoulder block is cylindric, air outlet hole is arranged on the sidewall of cylinder, rubber sleeve is contained on the cylindrical wall of valve inside shoulder block lower end, the valve core print seat is the cylinder that has flange, top at the valve core print seat is provided with screw thread, on valve core print seat mouth upper-end surface, flat rubber pad is installed, valve inside is installed on the valve core print seat, the discoidal shoulder block of valve inside matches with flat rubber pad on the gaseous core seat mouth upper-end surface, and nut is with the shoulder block of valve inside and the flat rubber pad compression fit on the valve core print seat mouth upper-end surface.
Flat rubber pad compression fit on the shoulder block of valve inside of the present utility model and the valve core print seat mouth upper-end surface, make the valve cock sealing, prevent that gas from running out of from valve core print seat mouth, because the plane and the plane, valve core print seat mouth upper-end surface of shoulder block compress flat rubber pad, flat rubber pad is difficult for being squeezed broken, long service life, suit rubber pipe on the cylindrical wall of valve inside lower end, rubber pipe adopts the strong rubber of tightening force to constitute, can seal the air outlet hole of valve inside effectively, prevent that valve inside from leaking slowly, because the conical section of former valve inside that gone to disappear, thereby avoided the rubber pipe of the conical section of valve inside to be squeezed broken phenomenon easily.
Accompanying drawing is a structural representation of the present utility model, below in conjunction with accompanying drawing the utility model is further described, the flat envelope of a kind of bicycle inner tube valve cock, comprise the valve core print seat, valve inside and the rubber pipe that is sleeved on the valve inside, the lower end that has the valve inside 1 of disc shoulder block is cylindric, air outlet hole 5 is arranged on the sidewall of cylinder, rubber pipe 4 is sleeved on the cylindrical wall of valve inside 1 shoulder block lower end, the cylindrical wall of valve inside 1 cylindric end is provided with projection 7, projection 7 can be the taper shape of shouldered, projection 7 also can be a block, the projection 7 of cylindrical wall end is blocked rubber pipe 4, prevent rubber pipe 4 displacements and slippage, valve core print seat 6 is for having the cylinder of flange, its top is provided with screw thread, on 6 mouthfuls of upper-end surfaces of valve core print seat, flat rubber pad 2 is installed, valve inside 1 is installed on the valve core print seat 6, flat rubber 2 pads on 6 mouthfuls of upper-end surfaces of valve inside 1 discoidal shoulder block and valve core print seat match, nut 3 is with the shoulder block of valve inside 1 and flat rubber pad 2 compression fit on valve core print seat 6 upper-end surfaces, flat rubber pad 2 long service life, be difficult for being squeezed broken, slowly leak for preventing valve inside 1, seal air outlet hole 5 effectively, can adopt the big rubber pipe of high strength and tightening force 4, also double-layer rubber pipe 4 can be installed on gaseous core 1.
