Abstract
The utility model relates to a needle valve type air valve inflating valve. The front end of a fixing jacket is provided with a hole which is matched with the outer diameter of the air valve of a tire, and the inner side of the hole is a rubber pad. An outer jacket with an inflating nozzle is positioned at the inner cavity of the fixing jacket, the front end of the outer jacket is contacted with the rubber pad, and the back end of the outer jacket is provided with a sealing ring which is contacted with the inner side of a retaining nut connected with the back end of the fixing jacket in a thread mode. A spindle with the front end provided with a valve needle groove is sheathed and inserted on the retaining nut, and is positioned at the inner cavity of the outer jacket, and the back end of the spindle is provided with a hand wheel. The inflating valve finishes loading and unloading the valve needle of the tire in a closed hollow cavity. The utility model not only can fast inflate, but also prevent air from leaking out.
Description
The utility model relates to inflatable tool, particularly uses the special-purpose gas charging valve of needle valve air lock nozzle tire.
What automobile tire, motorcycle tire and partially self vehicle tyre used is needle valve air lock nozzle, when inflation, plunger to be backed out with special spanner in valve cock, again pump is aimed at valve cock inflation (do not back out plunger, inflation effort and aeration speed are slow).Back out plunger to the moment of tracheae being aimed at valve cock and be full of gas after pull up tracheae and the moment of the plunger of screwing on, all have a large amount of gas to release.According to measurement, when a skilled fixer is tyre inflation, during 8 barometric pressure of pressurising, pull up tracheae fast and speed is screwed on plunger, only surplus 7 barometric pressure in this moment tire.
The purpose of this utility model is to provide a kind of needle valve air lock nozzle special-purpose gas charging valve, has both made things convenient for fast aeration, can prevent gas leak again.
Technical solution of the present utility model is: the needle valve air lock nozzle gas charging valve, comprise charging air inlet, plunger spanner, the fixed cover front end has the hole that coincide with the tyre valve external diameter, the inboard, hole is a rubber pad, the overcoat of band charging air inlet is positioned at the fixed cover inner chamber, and front end and rubber pad touch, and rear end band seal ring touches with the tightening nut inboard that is threaded with the fixed cover rear end, the axle that the cover of front end band valve groove is inserted on the tightening nut is in the overcoat inner chamber, rear end band handwheel.The overcoat inner chamber is equipped with the heart cover that play the guiding role, and passing on the axle of heart cover inner chamber has spring, the steel wire card center roller limitation locking that heart cover rear end inner chamber is installed.
According to technique scheme, charging air inlet and cover that the air-filled pore of gas charging valve is aimed on the tire are plugged, turn tightening nut, the promotion overcoat moves ahead, with the extruding of the rubber pad in air-filled pore modification, make it tightly wrap valve cock, touch handwheel, the plunger groove of axle front end entangles plunger, rotation hand wheel, the cutting edge on the plunger cooperates with notch on the axle, and plunger is screwed off, this moment, tire and charging air inlet were used to lead to, and inflation gets final product.Inflation finishes, and the counterrotating handwheel is screwed on plunger.Because plunger is backed out, can make things convenient for fast aeration, be in closed chamber, to carry out because of turning air tube again, can prevent to lose heart.
Accompanying drawing is the utility model structural representation.
In conjunction with the accompanying drawings, embodiment of the present utility model is described.The needle valve air lock nozzle gas charging valve, comprise charging air inlet, plunger spanner, fixed cover 13 front ends have the hole that coincide with the tyre valve external diameter, the inboard, hole is a rubber pad 14, the overcoat 10 of band charging air inlet 3 is positioned at fixed cover 13 inner chambers, and front end and rubber pad 14 touch, and rear end band seal ring 9 touches with tightening nut 4 inboards that are threaded with fixed cover 13 rear ends, the axle 6 that the cover of front end band valve groove 1 is inserted on the tightening nut 4 is in overcoat 10 inner chambers, rear end band handwheel 7.Overcoat 10 inner chambers are equipped with the heart cover 11 that play the guiding role, and pass the heart and overlap on the axle 6 of 11 inner chambers spring 12 is arranged, and the heart overlaps steel wire card 5 center rollers 6 limitation lockings that 11 rear end inner chambers are installed.The installation conduit 2 that has the charging air inlet 3 that is used on the overcoat 10 on the fixed cover 13.Handwheel 7 is locked by iron pin 8 with axle 6.
