Description
The utility model relates to the connection nipple of a kind of motorcycle, cycle wheel inflation usefulness.
Existing motorcycle and most of mountain bike, racing car etc. are when tyre inflation, all need add an inflation and connect mouth, this connects mouth is made up of thread nozzle and plunger tip, during use, inflation connects mouth and is clamped by pump clip earlier, and then be spun on the tyre valve, the thread nozzle space that connects mouth owing to spinning is little, operates very inconvenient, and in thread nozzle spins the process of valve inside, tyre valve core is in the gas leakage state always, just stops gas leakage when thread nozzle screws, and just inflated by gas cylinder this moment.Charge when screwing off thread nozzle behind the gas and occur above-mentioned gas leak phenomenon again, it is more serious to leak gas.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of easy to use and solved the motorcycle bicycle use leakless valve of a gas leakage difficult problem.
Technical solution of the present utility model:
A kind of motorcycle bicycle use leakless valve, it is by activity air inlet top (1), guide sleeve (2), sealed air valve rubber cushion (3), seal cartridge (4), seal rubber pad (5), housing (6), Returnning spring (7) is formed, it is characterized in that housing (6) is an inner hollow body, the lower end surface has the inner bolt hole that matches with motorcycle or bicycle valve cock outside thread, be lined with seal rubber pad with holes (5) in housing (6) inner hollow body bottom surface, be provided with seal cartridge (4) in the housing inner hollow body on seal rubber pad (5), be provided with Returnning spring (7) in the seal cartridge (4), (1) top, activity air inlet top is hollow body, the bottom is thin solid cylinder, and the lower end outer wall of its hollow body in top has the air outlet hole (8) that is communicated with hollow body, the outer wall position of corresponding this air outlet hole of hollow body (8), be provided with sealed air valve rubber cushion (3) in housing (6) inner chamber relevant position, it is sealed air outlet hole (8) under normal conditions, the thin solid cylinder in air inlet (1) bottom, top penetrates in lining (4) and the Returnning spring (7) thereof, and the lower end of thin solid cylinder is positioned at the upper end of seal rubber pad (5) center hole, there is outside thread guide sleeve (2) lower end, the chuck of upper end for matching with the inflator dop, center is for coming directly towards the through hole that (1) hollow body matches with the activity air inlet in it, it is sleeved on the hollow body of air inlet top (1) and is screwed in the internal thread of housing (6) upper end-hole, and housing (6) and activity air inlet top (1) are connected as a single entity.
The utility model adopts the sealing air-supported structure, and it is in closed state all the time when screwing on or screw off tyre valve, and when inserting gas cylinder, connects mouth and be communicated with valve inside, finishes gas replenishment process.The utility model connects inflator thereafter again owing to earlier connect mouth to valve cock, so manipulate very conveniently, and has thoroughly solved a gas leakage difficult problem when connecing mouth and screwing on or screw off, has good use value.
Fig. 1 is a structural representation of the present utility model;
Structural representation when Fig. 2 is the utility model inflation work;
Fig. 3 is the structural representation that the utility model adopts non-metal part.
As Fig. 1, the hollow body in top of the utility model activity air inlet top (1) and the junction of the thin solid cylinder in bottom are a step (9), the lower surface of this step (9) is pushed down the upper end of Returnning spring (7), and its upper surface is against the lower surface of sealed air valve rubber cushion (3).The air outlet hole (8) of hollow body lower end, (1) top, activity air inlet top outer wall is relative two, and their generally all sealed valve rubber cushions (3) are sealed.Housing of the present utility model (6) is if adopt the non-metallic material materials and parts, and as plastics etc., as Fig. 3, then its lower end mouth inwall can stud with the metal internal thread cover (10) that matches with motorcycle or bicycle valve cock outside thread, can reduce cost greatly like this.Equally, the non-metallic material materials and parts also can be adopted in activity air inlet top (1), and the thin solid cylinder in its underpart is taper, to increase its axial strength.
When the utility model uses, valve cock external thread rotary with housing (6) lower end inner bolt hole or metal internal thread cover (10) and motorcycle or bicycle is connected together earlier, the valve inside of valve cock does not back down owing to being depressed by activity air inlet top (1), so valve inside can not leak gas, the phenomenon that nausea is outwards run can not appear taking turns.And then with the pump clip clamping of gas cylinder on the chuck of guide sleeve (2) upper end, then under the effect of pump clip, the air inlet of inflator valve alignment activity comes directly towards the hollow body in (1) top and pushes down it is moved down, at this moment, the thin solid cylinder in (1) bottom, activity air inlet top enters in housing (6) lower end interior threaded hole or the metal internal thread cover (10) valve inside of motorcycle or bicycle valve cock depressed and backs down, simultaneously, in activity air inlet top (1) folding process, owing to breaking away from sealed air valve rubber cushion (3), its top hollow body lower end outer wall air outlet hole (8) enters in seal cartridge (4) chamber, as Fig. 2, then tyre valve core is in connected state by activity air inlet top (1) and gas cylinder valve, this moment, tire can not leak gas yet when gas cylinder is not inflated owing to compress even at the cost of one's life up and down.When inflator is inflated, pressurized gas enter from the hollow body in top of activity air inlet top (1), and send from its lower end air outlet hole (8), constantly charge in motorcycle or the bicycle tyre, till being full of by seal cartridge (4) inner chamber and seal rubber pad (5) center hole.After charging gas, earlier inflator is taken off, the position is retracted in activity air inlet top (1) under the effect of Returnning spring (7), the sealed again valve rubber cushion of its air outlet hole (8) (3) is sealed, make the utility model be in sealing state again, tire still can not leak gas, and screws off housing (6) at last and promptly finishes whole gas replenishment process.
