Abstract
The utility model relates to an air valve of a bicycle, which is characterized in that the air valve of a bicycle is provided with a through type valve body whose upper section is provided with external threads, and the middle section of the through type valve body is provided with two symmetrical side ears. Annular grooves which are inversely conical is arranged below the side ears, and the bottom of the valve body is provided with a discoid valve core with a sealing ring groove. A valve rod which is fixedly connected with the valve core is positioned in a valve cavity. Meanwhile, a pressing spring is arranged in the valve cavity, and the upper end of the pressing spring is abutted with the rod head. The lower end of the pressing spring is abutted with the lug boss of the inner wall of the valve cavity The utility model has the advantages of good sealing performance and long service life, and the utility model can be matched with the existing traditional air valve seat.
Description
The utility model relates to tyre valve core, more particularly, is a kind of tyre valve core that is particularly useful for rickshaws such as bicycle, flatcar.
The bicycle valve core that tradition is used is to adopt the bypass type valve body to cooperate with emulsion tube, utilizes the elasticity realization valve inside of emulsion tube itself and the sealing between the valve seat, and the unidirectional conducting of valve inside.Because the seal section between valve inside and the valve seat is a flat segments, therefore the emulsion tube aging quality resistance is relatively poor in addition, and the valve inside poor sealing performance of this structure, working life are short, and the problem of bringing simultaneously is to use inconvenience, tire needs frequent tonifying Qi, and changes emulsion tube.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and the valve inside of a kind of good seal performance, long service life is provided, and uses with convenient.
The purpose of this utility model is achieved through the following technical solutions.
The utility model adopts the straight-through type valve body, and the epimere of described valve body has outside thread, and the stage casing has two of symmetry to pick up the ears, and ring-type inverted cone groove is arranged under picking up the ears.Be provided with the plate-like spool of seal groove in the bottom of valve body, the valve rod that connects firmly with this spool is positioned at valve pocket, simultaneously, in this valve pocket stage clip is set, and the bar head is supported in the stage clip upper end, and valve pocket inwall boss is supported in the lower end.
Compared with the prior art, the utlity model has following advantage:
1, the ring-type inverted cone groove that is used for fixing sealing that the utility model is provided with on the valve body periphery in use, has greatly strengthened the sealability between valve inside and the valve seat.Adopt this sealing configuration, can guarantee does not need tonifying Qi in half a year under the intact prerequisite of tire itself.
2, the utility model does not have easily damaged parts, long service life.
3, the utility model and valve seat of the prior art are supporting, can arbitrarily change traditional valve inside, and it is convenient to implement.
Accompanying drawing is the utility model structural representation.
By the following examples, in conjunction with the accompanying drawings, the utility model is further described.
Embodiment:
Referring to accompanying drawing, valve body 1 is a straight-through type, and its valve interior wall has a boss 8, at the valve body epimere outside thread 2 is arranged, and this outside thread 2 matches with employed valve cap internal thread in the prior art.The outside stage casing of valve body 1, what symmetry was arranged two picks up the ears 3, and this picks up the ears 3 corresponding with two ear groove positions on the valve seat in the prior art.Picking up the ears down, ring-type inverted cone groove 4 is arranged, this groove 4 is used to place seal ring, to sealing between valve seat and the valve inside.As shown in the figure, be provided with the plate-like spool 5 of seal groove in the bottom of valve body 1, in seal groove, place seal washer 10.Shown in the figure, valve rod 6 connects firmly with spool 5, and valve rod 6 is positioned at valve pocket, and there is bar head 7 its upper end.Be provided with simultaneously stage clip 9 in valve pocket, bar head 7 is supported in stage clip 9 upper ends, and valve pocket inwall boss 8 is supported in the lower end.
In the use, in inverted cone groove 4 and seal spool ring recess, place seal ring respectively.The valve inside described with present embodiment substitutes valve inside in the prior art, gets final product on the device valve seat in the prior art.
The utility model is equally applicable to flatcar etc.
