CN85205571U - Self air-inflation device for bicycle - Google Patents

Abstract

The utility model belongs to the bicycle manufacturing profession, which provides a device which solves the problem that a bicycle on a running way can freely inflate a tyre. The utility model has the primary structure that a tube is erected on a bicycle as the cylinder body of an inflating cylinder, and a draw rod with two direction balls and a handle which can be thumbed in a groove of a bicycle seat are additionally arranged to make the bicycle and the inflating device become a whole, rather than an additional device. So long as the utility model is connected with an air-guide tube, the draw rod is pulled, and the device can inflate the tyre at any time and at any place.

Description

Self air-inflation device for bicycle

The utility model is a kind of bicycle self gas filled device, and it has improved gas filed conventional tool of bicycle and method.Particularly it can satisfy bicycle and goes out to travel midway outside, tire does not have gas suddenly, be badly in need of not relying on any special inflatable tool and can be whenever and wherever possible to this requirement of Tyre inflating, be applicable to 28 types, 26 types, 24 type bicycles and the various power actuated vehicles of forming with pipe fitting, as three-wheel vehicle, tricycle for the disabled etc.

The inflation of traditional bicycle needs independent special inflatable tool, as treadle air pump, this inflatable tool heaviness, carries with car when being not easy to go out, and therefore, can't resolve bicycle and goes out to travel and need gas filed problem in the way.Also have a kind of hand-held perpendicular Floor Pump, be attached on the vehicle frame at ordinary times, solved with car and carried problem, but its cylindrical shell capacity is little, and charge efficiency is low, general little women and the elderly of arm strength, use it to feel gruelling, tire is filled less than the pressure requirement that should reach, and its price up to 15 yuan on, uneconomical.

This device is intended to solve people and need not to be equipped with in addition special inflatable tool, and in the way of travelling, tire does not have gas suddenly, and the cyclist can not utilize bicycle self device timely by any inflatable tool, to this problem of Tyre inflating.

For achieving the above object, the design of this device is that bicycle and inflator pump are combined.The cylindrical shell of inflator pump of promptly having selected a sub-double as of oblique vertical tube below the vehicle seat for use, make this manage a thing dual-purpose, for adapting to the tiltedly perpendicular feature of this pipe, in the middle of piston and pull bar, add two multi-directional ball, make pull bar be converted into different angles and do not influence the leak tightness of piston, pull bar is threaded with adjusting length with handle, to adapt to different height human needs, again for ease of the collection handle, there is handle to place groove on the vehicle seat, handle can be inserted in the vehicle seat groove at ordinary times, and the ventilation flue be put into the tube chamber of handlebar.Like this, just bicycle and inflatable tool are combined into a non-removable integral body cleverly, have given bicycle a kind of self gas filed function.Therefore, no matter bicycle is ridden up to the there, can be on demand whenever and wherever possible to Tyre inflating.

This device is compared with tradition inflation technology, its advantage has been to save the trouble that special independently inflatable tool is set and needs at ordinary times to carry and take care of, and simultaneously total cost does not improve, and has reduced on the contrary, make manufacturer lucrative, make the customer feel practical, convenient, economical.

Accompanying drawing is a scheme drawing, and in conjunction with the accompanying drawings, the utility model is described in further detail.

Oblique vertical tube (1) below the bike saddle, its tube cavity is smooth through handling, in the lower end of this pipe is sealing termination (2), the dead lower end of its sealing makes it and can not leak gas, back wheels of vehicle one side is leaned in top in sealing termination (2), being equipped with gives vent to anger chews (9), dress universal check valve of packed-piston (3) and pull bar (5) multi-directional ball (4) in the pipe, they are the oblique vertical tube feature design-calculateds for bicycle, when purpose makes the pull bar crank motion, pull bar can freely be converted into arbitrarily angled and unlikely tilting of the piston with oblique vertical tube, influences other leak tightness.In the upper end of pull bar, be to regulate length screw thread (6), it can elongate or shorten because of the height of different people.Regulating length screw thread (6) links to each other with handle (7).Handle is pressed in the groove that can put handle vehicle seat (6) at ordinary times, and the outside adds saddle cover during rider, makes rider comfortable.Connection mouth (10) and ventilation flue (11) form together.Be placed at ordinary times in the cavity (12) of headstock handgrip.Whole structure is simple like this.

During use, connection mouth (10) one ends at ventilation flue (11) two ends are chewed (9) and are connected with giving vent to anger, an end is connected with the tire valve inside, and draw-out handle (7) from the vehicle seat just can be to Tyre inflating.No matter ride up to the there, can use whenever and wherever possible, very convenient.But the cyclist's health that should be noted that is shorter, as when feeling that handle position is higher, can be placed on lower to bicycle in use, and the people stands in eminence, and as car being placed on the road limit, the people stands on the step on footway, can solve height problem.

Claims (4)

1, a kind of bicycle self gas filled device, sealing termination (2) is equipped with in the bottom that it is characterized in that the oblique vertical tube (1) below the bicycle saddle, there is air extractor duct (9) lower end, the universal check valve of packed-piston (3) can be at oblique vertical tube (1) inwall crank motion, and be connected with handle (7) by pull bar (5), can place the ventilation flue (11) of band connection mouth (10) in the headstock handgrip (12).

2, bicycle according to claim 1 self gas filled device is characterized in that multi-directional ball (4) is arranged on the pull bar (5).

3, device according to claim 1 is characterized in that being provided with between pull bar (5) and the handle (7) adjusting length screw thread (6).

4, device according to claim 1 is characterized in that handle (7) can be pressed can put in the handle vehicle seat (8) when not inflating.
