Abstract
The utility model discloses an inflating valve with a movable core, which is composed of a housing body (1), a movable core (2), a sealing washer (3) and an ornamental ring (4). The inflating valve can be well connected with a tyre valve in advance, and then, is connected with an inflator. The utility model utilizes the spring force of an inflator clamp to cause the movable core to be pressed in by the valve core of the inflator. Thereby, the tyre valve is opened until the utility model is connected with the inflator. After the inflation is finished, the inflator valve is directly taken off, and the movable core is quickly restored to be at the original position under the function of the spring force of the tyre valve and the high-pressure air of the tyre. A one-way valve composed of the tyre valve, a conical head and a conical hole automatically close. The utility model is used conveniently and flexibly, and the utility model can not generate the phenomenon of air leakage.
Description
The utility model relates to a kind of automobile or motorcycle tire charging air inlet, and the charging air inlet of slide core is especially arranged.
In daily life, automobile or motorcycle tire be often inflation always, because of pump adaptor can't directly be connected with cranked tire valve, so the special-purpose charging air inlet of the two occurred being used to cooperate.Have only unique a kind of fixed charging air inlet in the market, when utilizing this charging air inlet to inflate since with the cranked tire valve connection procedure in, tire valve is opened gradually, the straight-through atmosphere of air chamber in the tire, so this charging air inlet should at first link to each other with pump adaptor.But the charging air inlet volume is less and pump clip is bigger, very inconvenience of operation when this just causes charging air inlet to be connected with cranked tire valve again, and in connection procedure, still have a large amount of gas leaks.
The purpose of this utility model provides a kind of easy to use and gastight slide core charging air inlet.
For achieving the above object, slide core charging air inlet of the present utility model is made up of housing, slide core, seal washer and ring.For flexibly connecting, slide core moving by the bulge loop through roll forming in cone shape hole and the straight hole in housing limited between slide core and the housing.During use, only need this charging air inlet directly is screwed on the cranked tire valve, after putting in place, the valve inside of cranked tire valve just withstands on the conical head end face of slide core, and this moment, tire valve was not opened.When pump clip was sandwiched in gas letter mouth on the charging air inlet, slide core was compressed into by pump adaptor, and slide core moves, and promoted tyre valve core and opened valve, and conical head leaves cone shape hole simultaneously, and gas circuit is unimpeded, and at this moment, available inflator is inflated.When inflation finishes, take off pump clip, slide core returns to initial state very soon under the effect of tyre valve core spring force and tire pressure, and conical head is blocked gas circuit, and tyre valve core is also closed valve simultaneously.Charging air inlet both can take off also and can be put on the cranked tire valve always.
Adopted after such structure, can earlier charging air inlet be screwed on the cranked tire valve, and then pump adaptor has been connected on the charging air inlet, very easy to use.Because conical head plays the effect of one-way valve, even wearing and tearing or wear out, seal washer causes that tire valve is crack, phenomenon can not leak air yet.
Below in conjunction with accompanying drawing and implementation methods the utility model is described in further detail.
Fig. 1 is the phantom of the utility model slide core charging air inlet;
Fig. 2 is the sectional view of the utility model slide core charging air inlet along the A-A line;
Fig. 3 is the connection diagram of the utility model slide core charging air inlet and cranked tire valve;
Fig. 4 is the connection diagram of the utility model slide core charging air inlet and pump adaptor;
Slide core charging air inlet shown in Figure 1 is made up of housing (1), slide core (2), seal washer (3) and ring (4), and housing (1) and slide core (2) are for being slidingly connected.Housing (1) is made up of nut (5) and circular hole (9), and nut (5) is used for charging air inlet is threaded with cranked tire valve.Seal washer (3) is used for increasing the tightness of charging air inlet and cranked tire valve.Cone shape hole (7) cooperates with conical head (6), has both played the effect of one-way valve, but restraint core (2) skids off to circular hole (9) end again.At circular hole (9) inwall the bulge loop (8) of roll forming is arranged, but its restraint core (2) skids off to nut (5) end.Slide core (2) is oblate and a rectangle groove (10) is arranged by circular hole (9) end, is used for increasing when cooperating with pump adaptor the vent ability of gas circuit.Pump adaptor (12) is with after charging air inlet is connected, and valve inside (11) withstands on the end face of slide core (2), as does not have groove (10), and then slide core (2) is blocked valve inside (11), and gas circuit is obstructed, can't carry out inflation work.When fluted (10), gas just can enter the gap of circular hole (9) and oblate type slide core (2) from valve inside (11) through groove (10).To the mobile Δ d distance of nut (5) end, conical head (6) leaves cone shape hole (7) to slide core (2) under the effect of pump clip, and one-way valve is opened; Simultaneously, conical head (6) is to the also mobile Δ d of valve inside (13) distance of circular hole (9) end promotion cranked tire valve (14), and tire valve is opened; So far, gas circuit is all unimpeded, utilizes inflator can carry out inflation work.When inflation finishes, take off pump adaptor (12), slide core (2) is under the effect of tyre valve core spring force and tire inner high voltage gas, return to initial position very soon, tire valve is closed, conical head (6) is also closed automatically with the one-way valve that cone shape hole (7) is formed simultaneously, so far can take off charging air inlet, also charging air inlet can be put on the cranked tire valve (14) always.
Certainly, housing of this slide core charging air inlet (1) and slide core (2) also can have its shape and structure, but as long as adopt the slide core principle, all drop within the protection domain of the present utility model.
Claims (4)
1, a kind of slide core charging air inlet that is used for automobile or motorcycle tire is made up of metal shell (1), slide core (2), seal washer (3) and ring (4), is flexible connection between slide core (2) and the housing (1).It is characterized in that: housing (1) reaches the circular hole (9) that cooperates with pump adaptor by the nut that cooperates with cranked tire valve (5) to be formed, and slide core (2) can be done moving of certain limit in circular hole (9).
