Abstract
The utility model relates to an enter-gas nozzle structure that can ensure the inner volume of boosting air pressure, mainly comprising a gas nozzle thimble set in the connector the enter-gas nozzle and in the connector base of the gas nozzle, one end of the gas nozzle thimble side through the connector base of the gas nozzle is arranged in one end of a high-pressure pipe, the gas nozzle thimble can flex through rotating the high-pressure pipe, the end provided with the thimble of the gas nozzle thimble is positioned at the opening of the connector of a gas nozzle shaft through the gas nozzle sealing gasket, and the connector of the gas nozzle shaft is positioned on the connector base of the gas nozzle. The useful effect of the utility model is that, after enter-gas is completed, the gas nozzle thimble will be opened through the high-pressure pipe, which is connected with the gas nozzle thimble, and this will enable the thimble in the gas nozzle and the enter-gas valve of the gas nozzle of enter-gas objects to separate in advance, and then let out the residual gas in the high-pressure pipe through a gas discharge valve, thus not causing gas leakage, thereby effectively ensuring the inner volume of boosting air pressure and the necessary air pressure value.
Description
Technical field
The utility model relates to a kind of charging air inlet of pump, refers in particular to a kind of charging air inlet structure of guaranteeing to inflate the air pressure inner capacities.
Background technique
General pump all is provided with the charging air inlet that engages with the Pneumatic article valve, Pneumatic article is inflated again.What existing pump charging air inlet design was adopted is the air outlet of a valve shaft coupling being located at the pump high-pressure air pipe, is provided with a valve thimble in the valve shaft coupling.During use, the valve shaft coupling of charging air inlet is tightened on the valve screw thread of Pneumatic article, at this moment, the valve thimble in the valve shaft coupling with shaft coupling inwardly screw and the valve gas charging valve that backs down Pneumatic article inflate.The charging air inlet structure of this pump in use can there are the following problems: after Pneumatic article is finished inflation, when the valve shaft coupling of pump charging air inlet will separate the valve of Pneumatic article, can cause Pneumatic article to leak partly gas, this be because the valve shaft coupling in the valve thimble with shaft coupling outward winding and Pneumatic article valve suction valve at this moment do not close fully, cause Pneumatic article to leak gas.Actual aeration quantity is not inconsistent with regard to forming Pneumatic article air pressure inner capacities like this, particularly needs the Pneumatic article of more accurate atmospheric pressure value for some, just can't guarantee to inflate the inner capacities and the required atmospheric pressure value of air pressure at all.
Summary of the invention
The purpose of this utility model is to provide a kind of charging air inlet structure of guaranteeing to inflate the air pressure inner capacities, and it can not cause gas leakage after Pneumatic article is charged gas, can effectively guarantee to inflate air pressure inner capacities and required atmospheric pressure value.
In order to achieve the above object, the utility model is realized by following technological scheme.
A kind of charging air inlet structure of guaranteeing to inflate the air pressure inner capacities, mainly by pump handle, outer tube, valve seat, one-way cock, air-outlet valve, barometer, high-voltage tube and charging air inlet joint are formed, be assembled in the outer tube pump handle and start back and forth, valve seat one end assembling one-way cock is connected with outer tube, air-outlet valve, barometer is located on the valve seat, the valve seat the other end connects high-voltage tube, it is characterized in that: the charging air inlet joint is organized in the valve connection block and is established a valve thimble, one end of valve thimble passes the valve connection block and is located in the other end of high-voltage tube, can make the valve thimble flexible by the rotation high-voltage tube, the valve thimble is provided with an end of thimble and is located at valve shaft coupling opening by the valve seal gasket, and the valve shaft coupling is located on the valve connection block.
The beneficial effects of the utility model are, during use valve shaft coupling of the present utility model is connected with the valve of object to be inflatable spare, at this moment, valve thimble in the valve shaft coupling can back down the valve gas charging valve of Pneumatic article, promptly inflatable with hand start pump handle back and forth then, required atmospheric pressure value is barometric reading, can lose heart by air-outlet valve as air pressure is too high.After inflation is finished, the valve thimble is outwarded winding by high-voltage tube, because of high-voltage tube is connected with valve thimble beer pressure, thimble in the valve is separated in advance with the valve gas charging valve of Pneumatic article, turn round the residual gas that releases in the high-voltage tube by air-outlet valve again, the valve of valve shaft coupling and object to be inflatable spare of coming loose again just can not cause gas leakage because this moment Pneumatic article gas charging valve seal, just can effectively guarantee to inflate air pressure inner capacities and required atmospheric pressure value.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model is further elaborated.A kind of as shown in accompanying drawing 1,2 guarantees to inflate the charging air inlet structure of air pressure inner capacities, mainly is made up of pump handle 1, outer tube 2, valve seat 3, one-way cock 4, air-outlet valve 5, barometer 6, high-voltage tube 7 and charging air inlet joint 8.
As Fig. 2, shown in Figure 3, be assembled in outer tube 2 in and back and forth start in conjunction with outer buffering O type ring 11, outer tube screw 12, interior buffering O type ring 13, axle center 14 pump handle 1, valve seat 3 one ends assembling one-way cock 4 is connected with outer tube 2, and outer tube 2 is provided with piston 21 and piston O type ring 22 with one-way cock 4 joints.Existing mature technology is adopted in above-mentioned combination, and each function is not partly done in detail at this and given unnecessary details to it.
As Fig. 2, shown in Figure 3, air-outlet valve 5, barometer 6 are located at below, the top of valve seat 3, valve seat 3 the other ends connect high-voltage tube 7 by a sealing cover 71 in conjunction with pump joint 72, and the end that pump joint 72 is provided with the barb line is located in the high-voltage tube 7, and the other end is located on the side of valve seat 3.By said structure, atmospheric pressure value is shown by barometer 6, high-voltage tube 7 and waiting fills the air pressure of object can be by air-outlet valve 5 venting.
As Fig. 2, shown in Figure 3, charging air inlet joint 8 is organized in valve connection block 81 and is established a valve thimble 82, the end that valve thimble 82 is provided with the barb line passes valve connection block 81 and is pressed in the other end of high-voltage tube 7 in conjunction with a sealing cover 83 beers, can make valve thimble 82 flexible by rotation high-voltage tube 7, the end that valve thimble 82 is provided with thimble is located at the opening of valve shaft coupling 85 in conjunction with O type ring 86, valve seal gasket 87 by two valve seal gaskets 84.Valve shaft coupling 85 is located on the valve connection block 81.
Via above explanation as can be known, a kind of charging air inlet structure of guaranteeing to inflate the air pressure inner capacities that the utility model provides, nationality is by can separate the valve gas charging valve of valve thimble 82 with Pneumatic article in advance by rotation high-voltage tube 7, can not cause gas leakage, guarantee the required atmospheric pressure value of Pneumatic article because of taking down the pump charging air inlet.
