Abstract

The utility model discloses an inflating device fixed on the vertical beam of a bicycle. Without limitations, an inflator can inflate the tyres anytime and anywhere. The utility model which has the optimum advantages of convenience for carrying and convenient operation is not easy to lose. Meanwhile, without adding any accessory structure, the bicycle matched with the device is integrated into a whole. With a hidden foldable handle of the utility model, the connection of the inflator body and the vertical beam, and the connection of a sealing nut at the head end of an air hose and a special bolt, the problem that the traditional inflator is inconvenient for carrying is solved.

Description

Inflator fixed on bicycle

The utility model relates to bicycle inflator.Design for tyre inflation whenever and wherever possible in order to solve bicycle.

Except going the inflation, be that oneself respectively is equipped with inflator pump when past people is the bicycle inflation, be the needs of tyre inflation whenever and wherever possible but can't resolve to the shop that repairs.Once the Inflator mounted on bicycle ┈ hand that occurred before this supports, inflates on the other hand, not only inconvenience but also not laborsaving and easily lose.It is reported, there is early stage the people to design bicycle " automatically " inflation air pump.Though this design has its " automatically " attribute, bicycle is intended to inflation, must overcome the normally work done of additional friction that air pump brings to bicycle.It is difficult to solve the needs of short distance inflation simultaneously.This device is not only very burdensome on the bicycle spoke, after mixing air pump and cam on the axletree, and is not suitable for the inflation needs of rise lock car and speed-varying vehicle.Equally, " bicycle is fixed with the car air-inflating device " that State Patent Office in 1989 is announced (CN2042305U), though there is it laborsaving, be not subjected to the advantage of time, region restriction, but only need install one on arc shaped blade wheel disc additional with regard to axis, just be enough to increase greatly difficulty in the manufacturing and the inconvenience in Consumer's use, moreover that how pneumatic tube shelves the problem of carrying is also also unresolved.

Some novel inflator design now, its advanced feature is often replaced by lengthy and tedious device designing institute, so that be accompanied by the impracticable characteristics that are difficult to overcome.

The utility model reaches the purpose that design is succinctly attractive in appearance, easily manufactured and be easy to carry and use in the hope of borrowing the chief of existing procucts on the basis of improving raising.

Structure of the present utility model is such: it is made up of gas tube, piston, piston rod, guide pillar, handle, O type circle, inflator base, air hose, sealing nut etc., it is characterized in that it has inflator pump is fixed on clip on the bicycle; And above-mentioned handle is folding, by the control gear of being made up of newel post, spiral plate, startup pin that makes handle place folded state or open configuration.

(Fig. 1 is the assembly figure of this model utility below in conjunction with accompanying drawing; Fig. 2 is the coupled condition figure of this model utility and bicycle; Fig. 3 is inflation mode figure; Fig. 4 is the erection drawing of pump handle and piston rod; Fig. 5 is newel post's structural drawing; Fig. 6 is Fig. 5 A-A sectional drawing; Fig. 7 is heterotypic bolt shape and key plan.) detailed description structure of the present utility model and using method:

First, by newel post, the parallel spiral plate of newel post's inwall, newel post's base, start pin (pin cap, fore-set, helical spring), gas tube, handle, the starting handle spring, guide pillar, piston rod, piston, O type circle, the inflator base, air hose, sealing nut, clip etc. partly form with the fixed inflator pump of car, its concrete structure and main effect are: 1, there are three sections to be evenly distributed on spiral plate (Fig. 5 that shape on the circumference is identical and be parallel to each other on newel post (11) inwall, Fig. 6), spiral plate and newel post are structure as a whole, its function is, when the operator is screwed newel post clockwise gently, spiral plate (2) promptly contacts with built-in startup pin pin cap (1) rotation, starts pin and makes progress parallel mobile along the spiral plate direction.When startup pin fore-set (3) disengaging was connected with the pin-and-hole of handle (4), root part of handle starting handle spring (5) ejected handle automatically, is work shape (7).Three sections spiral plates ask its parallel purpose to be to guarantee that newel post remains former horizontal operation state in spiral plate and the startup pin pin cap contact process in the newel post, solving newel post simultaneously need not to circle round, start the whole just problem of restorable of pin (when pin shade spiral plate direction moves to the spiral plate summit, just can be from falling, fall the preceding startup plane of next spiral plate, present the working state of next work cycle).So this device is the constant startup structure of screwing clockwise.2, between startup pin pin cap and the fore-set helical spring is housed, its role is to make start to sell remain stress state, promptly pin handle shape.When handle turns back in gas tube, the handle top circular arc portion will start the whole upwards promotion of pin gradually, and when fore-set entered in handle and the fore-set matching hole along the handle track, the helical spring driving started pin handle is pinned.3, pump handle is a collapsible device that is concealed in the pipe, and its root has a pilot hole (13) to be connected with a pin with piston rod part pilot hole (14), and both are become one.Install simultaneously a starting handle spring in connection procedure additional, one on spring is connected one and is connected (Fig. 4) with piston rod with handle, make handle produce driving force when activating to open.Just be intended for tyre inflation as the operator, screw newel post after, start pin and break away from and be connected with the pin-and-hole of handle, the starting handle spring ejects handle, is working state.Thereafter, the operator can take off air hose, with flexible pipe head end sealing nut (10) with prepare pneumatic tire valve (12) and connect after, hold handle, in the guide rail of guide pillar (6), fill up and down and beat, at this moment handle just drives piston rod and the reciprocal work done of piston, and pressurized gas is constantly charged in the tire.4, be installed on the guide pillar of piston rod part, effect is to prevent to produce parallel shift when handle from driving piston rod work, the positioning action when playing handle simultaneously and turning back.

The second, for solving the contradiction that inflator pump inconvenience is carried and easily lost, the inflator two ends have two snap-ring grooves (3a, b).Earlier a clip is crouched in groove during installation, another clip is stuck on the upright beam of bicycle then, connects with screw after the nut bore on two clips is just matching, and inflator (9) just firmly is positioned by the upright beam.Inflator two ends clip installation method is the same.

The 3rd, under situation about need not usually to tyre inflation, air hose is attached to (Fig. 2) on the bicycle cant beam.By the sealing nut of air hose head end be fixed on cant beam on be connected with the special-shaped stove bolt (15) of tire valve with bore, air hose just invests on the car steadily.This installation and design has not only solved practical, convenient, attractive in appearance problem, has increased the innervation during bicycle is advanced simultaneously and has not stayed the vestige of painstakingly chiseling and carving.

The production of this model utility is melted the die casting of non-ferrous metal and injection moulding in one, and with low cost, extensive market has certain popularizing value.
