Abstract
The utility model relates to an inflating air nozzle which comprises air nozzle seat sleeves (1, 2, 3 and 4), air valve cores (7 and 9), a sealing ring (8), a gland nut (5) and a sealing cover (6), wherein the air nozzle seat sleeves are same to the existing air nozzle seat sleeves; each of the air valve core is composed of a core body (7) and a sealing piston (9), wherein the inner end segment of a vent hole of the core body is provided with a piston cavity and an elastic columnar sealing piston; the air valve cores are tightly fixed in the air nozzle seat sleeves by the sealing ring (8) and the gland nut (5), and the sealing cover (6) is covered on the outer end head of an air inlet of each air valve core. The inflating air nozzle is inflated with labor saving. Meanwhile, the utility model has the advantages of good sealing performance and long air-preserving time.
Description
The utility model relates to the valve of various pneumatic tyre inflation usefulness, and is especially relevant with the bicycle inflating nozzle.
The valve inside of traditional bike tire's valve is owing to seal with envelope gas flexible pipe, and this makes that on the one hand inflation is very hard, is that sealability is relatively poor on the other hand, so bicycle is whenever inflated once, must inflate again after several days.
The purpose of this utility model is that a kind of inflating nozzle will be provided, and it can not only make inflation save labour, and its sealability greatly improves simultaneously.
The utility model comprises valve cover for seat, valve inside, seal ring gland nut and capping.The valve cover for seat is identical with traditional bicycle valve cover for seat.Cover is inserted with valve inside in the valve cover for seat.The inner section of the core body center roof vent of valve inside has a piston cavity, on piston cavity termination or the sidewall vent is arranged, and the elastic columnar shape that matches is housed in the piston cavity seals piston; In order to improve back plug sealability, piston and piston cavity inlet end can be processed into the taper shape that is complementary.One anti-gas-leak seal ring is housed between valve cover for seat and valve inside core body.The valve inside core body is fixed tightly in the valve cover for seat by gland nut by a buckle edge of table.Valve inside air inlet external end head is stamped capping.
The utlity model has following advantage: 1,, and adopted the piston type sealing mode, gas replenishment process is more saved labour because valve inside core body center roof vent the inner is got rid of and lost traditional suit hose sealing mode.2, because to seal piston be elastic material, and piston and piston cavity inlet end be taper, increases so its sealability is superior, protect the gas time.
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1. structural representation of the present utility model
As shown in the figure, the utility model comprises valve cover for seat 1,2,3,4, valve inside 7,9, seal ring 8, gland nut 5 and capping 6.Each parts 1,2,3,4 of valve cover for seat are identical with the corresponding part of existing bicycle valve cover for seat, and its fit is also identical.Cover is inserted with valve inside in the valve cover for seat, valve inside by core body 7 with seal piston and form, inner section at the vent at valve inside core body 7 centers has a piston cavity, there are vent 10,11 ventilation mouth cover for seat endoporus piston cavity sidewall or termination, the elastic columnar shape that matches is housed in the piston cavity seals piston 9.For improving sealability, piston and piston cavity inlet end can be processed into the taper shape that is complementary.One anti-gas-leak seal ring 8 is housed between valve cover for seat and valve inside core body.The valve inside core body is fixed tightly in the valve cover for seat by gland nut 5 by a buckle edge of table.Valve inside suction port external end head is stamped capping 6.
Claims (2)
