Description

Pocket hand-operated inflator

This model utility relates to a kind of inflator, particularly a kind of pocket hand-operated inflator of giving inflations such as bicycle, trishaw.

Common hand-operated inflator is huge and have a style of one's own because of the body frame, therefore carries inconvenience, and cost is higher.

The purpose of this new design provides a kind of pocket hand-operated inflator, and it can overcome common inflator and carry inconvenience, the shortcoming that cost is higher.

For achieving the above object, this design is carried out micro to traditional inflator and is handled, and be provided with link or valve cock and the homonymy of handgrip or heteropleural have a pair of sulculus two steel wires of close together can be vised at the end of the bobbin or the pole of calming the anger, therefore, this inflator can be attached directly on the wheel but not influence wheel.

The barrel tip of above-mentioned Miniature inflater is provided with the semi-circular recesses seat, can stride frame on cycle wheel axle axle skin; The opposite side of groove is provided with " Ω " clevis sheet or " U " shape buckle (bend the upper end clasp), and both cooperations can be the axle skin on the relaxed state hoop in barrel tip, just bobbin are connected on the skin, make inflator that fulcrum arranged, and are convenient to inflation.Loosen handgrip during use and be torqued into the direction vertical that handgrip can be slided between the steel wire gap, or it is just inflatable that inflator is tilted to wheel one side with steel wire.Can grow also and can lack as for air pipe; If long, can connect front-wheel and also can connect trailing wheel, the single use of this inflator; If short, directly be connected with the valve that is attached wheel, this inflator uses (each one of front and rear wheel) in pairs; Perhaps increase an air pipe and the public same inflator of inflator pipe that adheres on the wheel that is attached at the end, reach the purpose identical with long tube.

Above-mentioned inflator barrel tip also can be provided with little hook, little hook towards can be at the homonymy or the heteropleural of bobbin, make the inflator also can be attached on the axle skin.Loosen handgrip in case of necessity and be torqued into the direction vertical, handgrip can be slided by easy on and off between the gap of steel wire, reach the purpose of inflation with steel wire.

Above-mentioned inflator barrel tip also can be sent out and put valve cock and directly be connected with the valve stamen, makes bobbin attached to the wheel Lower Half, and the pole of calming the anger then makes long, makes handgrip adhere to the wheel first half, and can slide by easy on and off between the steel wire gap; Valve cock also can be connected with the valve stamen by sebific duct, and loosening handgrip during use, that inflator is tilted to wheel one side is just inflatable.

Above-mentioned inflator all can be inverted, and just has the semi-circular recesses seat or is provided with valve cock at the hollow pole end of calming the anger to be engaged on a skin or the steel ring, and be provided with the valve stamen or valve then becomes gas cylinder at the home position of piston or leather cup.Can be located at barrel tip as for handgrip and also can cover the disjunctor setting with bobbin.

Because in the above-mentioned solution, this model utility has been carried out the micro processing to traditional inflator, and be provided with " Ω " clevis sheet or " U " shape buckle or little hook or valve cock at the end of bobbin or the hollow an ancient wind instrument of calming the anger, and have sulculus on the handgrip, therefore this inflator can be integrated with bicycle, and is easy to use with low cost.

Be described in further detail below in conjunction with drawings and Examples:

Fig. 1 is first embodiment's plan view of this model utility:

Fig. 2 is an inflator handgrip plan view among first embodiment of this model utility;

Fig. 3 is that second embodiment's middle bobbin of this model utility colludes left view for a short time;

Fig. 4 is second embodiment's plan view of this model utility;

Fig. 5 is the 3rd embodiment's plan view of this model utility;

Fig. 6 is the 4th embodiment's plan view of this model utility;

Fig. 7 is " U " shape buckle plan view among the 4th embodiment of this model utility;

Fig. 8 is the 5th embodiment's plan view of this model utility.

Among Fig. 1, the end of bobbin 9 (containing screw thread) is connecting crescent moon seat 11 (containing screw thread), and the lower end of crescent moon seat 11 has groove and also passes through bolt " 12 " and " Ω " clevis sheet attached on the wheel axle skin 10.The other end of bobbin 9 is provided with bobbin lid 6, and the top of bobbin lid 6 is the handgrip 1 and the pole 5 of calming the anger; The calm the anger lower end of pole 5 is provided with piston 7, and the groove of piston 7 is with O-ring seals 8, and the two ends of handgrip 1 have handgrip sulculus 2, handgrip 1 can be clamped tightly on steel wire under steel wire 4 elastic force effects; Handgrip 1 can also reverse after the several angle from being eased up by the steel wire that clamped, and two ends are lofty respectively in the left side and the right side of steel ring 3, so that the operator's left hand and the right hand application of force are inflated to bicycle.During inflation, the air-flow of bobbin 9 is pressed in the inner tube of a tyre through sebific duct 13.

Among Fig. 2, the lean-in slightly two-phase of the sulculus 2 of handgrip 1 is echoed, so that steel wire is fastened handgrip 1 tighter under the elastic force effect, and difficult drop-off.The distance that the handgrip sulculus is 2, greater than by pincers between adjacent wires apart from 4-8mm, the length of handgrip 1 is about 120-150mm.

Among Fig. 3 Fig. 4, the both sides of bobbin 9 ends have aperture, and the heel 16 of little hook 15 buckles in the aperture under its elastic force effect; Little hook 15 can vise a skin 10, makes inflator have stressed fulcrum.

Among Fig. 5, bobbin 9 ends are provided with valve cock 17, and valve cock 17 can directly be connected by little rubber cushion with inner tube valve stamen 18.The pole 5 of calming the anger is long partially, so that 1 easy on and off slip between the gap of steel ring 3 top steel wires 4.

Among Fig. 6 Fig. 7, the pole 5 of calming the anger is the hollow pole of calming the anger, and its end has aperture, and the clasp 20 of " U " shape buckle 19 buckles in the aperture under its elastic force effect, thereby makes the pole 5 of calming the anger be relaxed state attached on the axle skin 10; The pole the other end of calming the anger connects piston 7, and the central position of piston 7 is provided with valve stamen 18 (also can be valve).Air pipe 1 is located at a side of pole 5 ends of calming the anger, and handgrip 1 is connected bobbin 9 ends.During inflation, take off handgrip inflator is tilted to wheel one side.

Among Fig. 8, hollow end of calming the anger pole 5 is provided with valve cock 17 and is connected with inner tube valve stamen 18 by sebific duct 13; Handgrip 1 is arranged on bobbin 9 lower ends with bobbin lid disjunctor.Because of the plasticity of sebific duct, this inflator both can stand in the wheel also that tiltable reaches the inflation purpose outside wheel.
