Abstract

The utility model discloses an Inflator type bicycle with an inflating function. An upright beam (15) part is improved. An inflating pull tube (16), a pull tube head, a leather cup (11), and a bottom screw are arranged in the upright beam (15), and an outer gas nozzle (12) is arranged. The utility model not only can be used for inflating tyres of the self bicycle, but also can be used for inflating tyres of other bicycles.

Description

The inflater type bicycle

The utility model relates to the improvement of bicycle structure.

Bicycle of the prior art does not possess the function of inflating, the design people's application and the utility model patent " inflater type bicycle " of having authorized make the upright beam of original bicycle into the Floor Pump form, both can give this car tire, inflate also can for other car tire, but some spare and accessory parts complex manufacturing technology, and changed the original mode of production of bicycle and process, also there are some defectives to be overcome in use.

The purpose of this utility model provides simpler, the practical more reliable convenience of a kind of making, installation and maintenance inflater type bicycle more simply and easily.

For achieving the above object, the utility model has adopted following technical scheme:

The utility model inflater type bicycle, comprise upright beam, inflate trombone slide, saddle holding screw, outer valve, outer valve has screw head, the trombone slide of inflating is arranged in the upright beam tube chamber, upright beam with inflate the top of trombone slide and all be drilled with the lockset through hole, the Li Liang bottom is drilled with outer air nozzle hole, and outer valve is arranged on this; Top at upright beam is equipped with the cylindrical body that an end has cylindrical boss, body is positioned at upright beam tube chamber, boss is positioned at outside the upright beam tube chamber, axially be drilled with a through hole along boss and body, the trombone slide of inflating therefrom passes, and is drilled with a lockset through hole along direction perpendicular to axial direction in body central authorities, and lockset through hole and Li Liang, the lockset lead to the hole site of inflating on the trombone slide are corresponding, the saddle holding screw is tightened on the body, is fixed; In upright beam tube chamber, inflate the trombone slide bottom and one end is installed has the cylindrical pullover of cylindrical boss, pullover being positioned at inflated the tube chamber of trombone slide, boss is positioned at inflates outside the tube chamber of trombone slide, have a screw head below the boss, central authorities' leather cup with holes passes screw head, is fixed on below the boss by nut; Below leather cup, be provided with the cylinder of a part of volume of vertically pruning vertically, bore a thread inleting hole vertically from the surperficial central authorities of the nearly leather cup end of cylinder, bore a screw thread air gate from the platform central authorities that are whittled into along direction perpendicular to axial direction, induction opening is connected with air gate, outer valve screw head passes outer air nozzle hole and screw thread air gate on the upright beam tube wall to be threaded, and is provided with rubber seal plug below cylindrical.

The utility model has the advantages that: the spare and accessory parts manufacture craft is simple, need not to change the original mode of production of bicycle and process, installation and maintenance are simple and convenient, technical more mature and reliable has overcome the defective that easily produces in a series of uses, leaks gas as outer valve place, leather cup is drawn out sometimes when inflating, easy bounce-back turnup is directly inflated the trombone slide downward pressure, cracky.

The utility model is described in more detail below in conjunction with drawings and Examples:

Fig. 1 is the front view of end screw;

Fig. 2 is the birds-eye view of end screw;

Fig. 3 is the front view of loam cake cover;

Fig. 4 is the birds-eye view of loam cake cover;

Fig. 5 is the structural representation of bushing needle;

Fig. 6 is the assembling scheme drawing of this novel inflater type bicycle.

Installation process at first is described:

The first step is packed rubber seal plug 10 in upright fine strain of millet 15 tube chambers into;

Second step, install as Fig. 1, end screw shown in Figure 2, with a special tool, be temporarily its adjusting lever, being actually an end is threaded, length is greater than the bar of upright fine strain of millet length, the screw thread of the screw thread of adjusting lever and end screw induction opening 1 matches, end screw is screwed on the adjusting lever, in upright beam 15 tube chambers of packing into, by adjusting lever adjustment location, screw thread air gate 2 is aimed at the outer air nozzle hole 17 that stands on the beam 5, install outer valve, then adjusting lever is screwed off taking-up, platform 3 makes the part around the upright beam 15 outer air nozzle holes 17 that a small amount of distortion take place, the area of contact of increase and outer valve 12 prevents gas leakage;

The 3rd step, loam cake cover as shown in Figure 3, Figure 4 is installed, the loam cake cover is through inflates on the trombone slide 16;

The 4th step, bushing needle as shown in Figure 5 is installed, pack into pullover 7 and inflate in the trombone slide 16, the leather cup 11 that central authorities are with holes passes screw head 9, is fixed on the boss 8 with nut 19, and boss 8 diameters are suitable with upright beam 15 internal diameters, a little bit smaller slightly, spur up and down when inflating inflating trombone slide 16 like this, can prevent leather cup 11 bounce-back turnups, in addition, bear the downward pressure of trombone slide 16 when inflating, increase compression area, give leather cup 11 with certain buffering, make its pressurized even, slow down breakage;

In the 5th step, the trombone slide 16 of will inflating is packed into and stood in beam 15 tube chambers, and is with saddle holding screw 13 that the loam cake cover is fixing.

Inflate process: when need not to inflate, it is fixing that lockset is passed lockset through hole 6; When inflating, lockset is taken off, push saddle up and down, through outer valve 12, be communicated with sebific duct, the air tube on the tire inflates a tire.

Maintenance process: holding screw 13 is turned on, held the boss 4 and the body 5 of loam cake cover and upwards extract, trombone slide 16 just can be taken out together with leather cup 11 grades, get end screw, and adjusting lever is screwed into end screw, backs out outer valve 12, with adjusting lever end screw is taken out of.
