Description
Technical field
The utility model relates to bicycle valve annex, is a kind of bicycle charging connector.
Background technology
Tire is the common name of tire, is made up of the inner tube of a tyre and cover tire as the one of which; Tire in the inner tube of a tyre is commonly called as refers to be used to keep inner pressure of tire, has tire valve the annular arrangement spring tube of (or claiming charging connector).This type of inner tube of a tyre need often inflate or inflate in use, but when as interior air pressure when not enough, can influence the effect of its use; And when air pressure is excessive, the situation that again it is blown out.For this reason; The tire tube valve of some inner tubes of a tyre is provided with explosion protection; Like the patent No. ZL200620107415.X that discloses in the Chinese patent document, September 15 2007 Granted publication day, utility model title " explosion-proof air valve of tyre "; This tire tube valve is made up of sealing cap, gasing sealed mouth, connection pipe, rubber bodies and superpressure blow off valve; Superpressure blow off valve self-opening can restore automatically when tyre inner pressure is reduced to superpressure blow off valve settling pressure value and close when gaseous tension in the tire surpasses superpressure blow off valve settling pressure value, makes the interior gaseous tension of tire remain on the settling pressure value.But above-mentioned tire tube valve structure is comparatively complicated, uses comparatively inconvenience.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of the utility model is to this area a kind of bicycle charging connector to be provided, and makes it solve the existing not good enough technical matters of like product structure design.Its objective is and realize through following technical scheme.
A kind of bicycle charging connector; This charging connector comprises block, presses core nut, plunger, India rubber tube, rim nut, mouth body, base; Said base is connected with an end of mouth body, and the external diameter of mouth body is provided with rim nut, and said block is connected with an end of plunger; The other end of plunger is connected with India rubber tube, and the junction of plunger and India rubber tube is provided with through hole; Said structure is identical with the charging connector of existing similar rubber tubular type, and gas gets into the inner tube of a tyre through the through hole of plunger.The other end that its structure design main points are said mouth bodies is connected with an end of explosion proof nut, and the other end of explosion proof nut is connected with pressing the core nut, and plunger and India rubber tube are arranged in the cavity of explosion proof nut and mouth body formation through pressing the core nut; Said explosion proof nut is provided with explosion-proof through hole, is provided with steel ball, spring in the explosion-proof through hole, and the explosion-proof through hole of spring section is provided with air gate, and steel ball offsets through the inner diameter hole of spring and explosion-proof through hole.The pressure that receives when steel ball is during greater than the elastic force of spring, and steel ball is retracted to the lead to the hole site of giving vent to anger, and the gas that gets into this charging connector is discharged through air gate, thereby prevents the generation of the situation of blowing out.This charging connector only needs through pressing the core nut unload the plunger of cap with cover and India rubber tube when explosion proof nut is installed, and behind the explosion proof nut of packing into, through pressure core nut the plunger explosion proof nut of packing into is got final product again.
The explosion-proof through hole of the other end of said spring is provided with set screw.Between elastic region, thereby regulate and set the air pressure range of this charging connector through the set screw regulating spring.
Said air gate is provided with the warning film.Alarm film diaphragm that is similar device, when the gas discharge vent occurs when "Bu" sound to remind those inflatable, tube gas pressure is too large.
The utility model reasonable in design, use, loading and unloading, air pressure adjustment are conveniently; The runflat device that is suitable as rubber tubular type charging connector when inflation uses, ex hoc genus anne the structural development of product.
Description of drawings
Fig. 1 is the half section structural representation of the utility model, and A portion has done to confine among the figure.
Fig. 2 is the A portion structure for amplifying scheme drawing of Fig. 1.
Figure number and title: 1, block, 2, press the core nut, 3, plunger, 301, through hole, 4, explosion proof nut, 401, steel ball, 402, air gate, 403, spring, 404, set screw, 5, India rubber tube, 6, rim nut, 7, the mouth body, 8, base.
The specific embodiment
Combine accompanying drawing at present, the utility model structure is further described with making to be used as.Like Fig. 1, shown in Figure 2, the base 1 that this charging connector comprises is connected with an end of mouth body 7, and the external diameter of mouth body is provided with rim nut 6; The other end of mouth body is connected with an end of explosion proof nut 4; One end of plunger 3 is connected with India rubber tube 5, and the plunger of band India rubber tube is inserted in the explosion proof nut, and the other end of explosion proof nut is connected with pressing core nut 2; Block is connected with the other end of plunger, and this charging connector gets final product installation.In the said structure, the junction of plunger and India rubber tube is provided with through hole 301, and plunger and India rubber tube are arranged in the cavity of explosion proof nut and mouth body formation through pressing the core nut; Explosion proof nut is provided with explosion-proof through hole, is provided with steel ball 401, spring 403 in the explosion-proof through hole, and the explosion-proof through hole of spring section is provided with air gate 402, and steel ball offsets through the inner diameter hole of spring and explosion-proof through hole; The explosion-proof through hole of the other end of spring is provided with set screw 404.
When this charging connector was inflated, gas got into the inner tube of a tyre through the through hole of plunger; But in interior air pressure was too high, the gas in the inner tube of a tyre acted on steel ball, and spring stress generation deformation moves to the air gate position until steel ball, and the excess air in the inner tube of a tyre is filled air gate and discharged.Simultaneously, use the inner tube of a tyre atmospheric pressure value of this charging connector, through the elastic force scope realization of explosion proof nut indirect regulation screw spring.
