CN2136889Y - Portable inflation tube with purpose of lock for bicycle - Google Patents

Abstract

The utility model relates to an auxiliary device for bicycle, which has two purposes of locking and inflating the bicycle. The pedal type inflation is adopted. A main inflator is also provided with a high-pressure air storage cylinder, providing the high-efficiency and labour-saving inflation. The lock seat of the bicycle lock is arranged on the base of the inflator. A coupling nut for an air nozzle of an air guide tube simultaneously serves as a locking pin. When the bicycle is locked, the air guide tube and an air-charging cylinder form a closed loop. The device is fixed to the beam of the bicycle through a simple movable connecting-component, and can be taken off by hand on the occasion of inflation. The entire device body is identical with a pedal inflator except additionally having the function of a lock; the utility model has portability and use for any time, and can lock both the bicycle and the inflator.

Description

Portable inflation tube with purpose of lock for bicycle

The utility model relates to a kind of car, dual-purpose bicycle accessories of inflation locked.

All kinds of in the market bicycle pumps can't not carry with car because of there being thief-proof parts, can not use at any time.China's patent gazette once publication number be 86201905,87210142,2051903U, 2075604U model utility, be with the vehicle inflator pump, what have also has lock car, an inflation double-purpose functional.But they or complex structure, cost is higher, carries inconvenience with car, and it is attractive in appearance to influence vehicle body; Or structure is too simple, and inflation is wasted time and energy, and efficient is too low, is difficult to use; Or it is inappropriate to utilize bodywork component to make device feature, causes manufacturing, use, maintenance extremely inconvenient.These shortcomings make them finally be difficult to commercialization.

The purpose of this utility model provides a kind of both small and exquisite economy, the inflator of convenient and practical again double as lock.

The utility model is made up of foot-operated inflator pump (1) and air pipe (2) two-part, is connected with bicycle by flexibly connecting parts (3).The base of inflator pump (1) is provided with lock (10); Air pipe (2) double as lock ring, the valve attaching nut (9) of its terminal double as lock pin again uses; Air pipe (2) is put by rubber pipe overcoat cylindrical screw bullet or metallic hose is made.

At ordinary times, this device is fixed on the appropriate location of each beam of bicycle by flexibly connecting parts (3), during bicycle parking, air pipe (2) passes wheel, valve attaching nut (9) the insertion inflator pump (1) of double as lock pin is gone up in the lockhole (10 ') of lock (10), air pipe (2) serves as lock ring, and inflator pump (1) formation one sealing ring, just pins bicycle.In the time of by bike, earlier open lock with key, allow air pipe (2) withdraw from wheel after, lock again.In the time of need inflating to bicycle, unblank earlier, throw off again and flexibly connect parts (3), take off whole device, inflator pump (1) is placed on the ground, valve attaching nut (9) on the air pipe (2) is threaded onto on the valve cock of bicycle inner tube,, can inflate to bicycle inner tube with the foot-operated dish (4) on the foot-operated piston rod (5) by reciprocally.

This device adopts foot-operated inflation, and inflator pump (1) is provided with high-pressure gas container (3) again simultaneously, makes inflation laborsaving efficient; The volume of foot-operated inflator pump own is little, with valve attaching nut (9), air pipe (2) and inflator pump base designs difference double as lock pin, lock ring and lock (10), makes structure compact more again.

The utility model compared with prior art, its advantage is: have lock car, self-locking and inflation combination function, simple and reasonable, meet use habit, inflate laborsaving efficiently, carry easy to operate.

Instantiation of the present utility model is provided by the following drawings:

Fig. 1 for the utility model fixedly the upright beam of car pin the schematic representation of trailing wheel.

Fig. 2 is the utility model structural drawing.

Fig. 3 for the utility model fixedly the car cant beam do not pin the schematic representation of front-wheel.

Fig. 4 is master, the left view of valve attaching nut (9) among Fig. 2.

Fig. 5 is master, the plan view that flexibly connects parts (3) among Fig. 1, Fig. 3.

Wherein, the each several part of Fig. 2 is expressed as follows:

4---foot-operated dish, 5---piston rod, 6---Returnning spring, 7---the inflation cylindrical shell, 8---high-pressure gas container, 9---the valve attaching nut, 10---lock, 10 '---lockhole.

The valve attaching nut (9) of Fig. 3 is made up of valve inside (11) and attaching nut (12).Attaching nut (12) has internal thread, and with the valve cock threads engaged of bicycle inner tube, it is inflatable to screw the back; Its external form special one-tenth circular arc head also has groove, and the lock core in grooved and the lock (10) matches.

The flexible connection parts (3) of Fig. 4 are made up of semicircle card (14) and spring clip (13), and they are fixed on the appropriate location of certain beam of bicycle by bolt, nut.Whole device is during with car, inflation cylindrical shell (7) can be pushed in the spring clip (13) to be fixedly clamped, and when needing inflation, opens lock, and slightly firmly from extracting inflation cylindrical shell (7) between spring clip (13), whole device is removed.

Claims (4)

1, a kind of inflator pump of double as bicycle lock is made up of inflator pump (1), air pipe (2) and lock, and it is characterized in that: inflator pump (1) is provided with lock (10), air pipe (2) double as lock ring, valve attaching nut (9) the double as lock pin of its terminal.

2,, it is characterized in that and to be movably connected with the beam of bicycle by the described inflator pump of claim 1 (1).

3,, it is characterized in that rubber pipe overcoat cylindrically coiled spring or metallic hose make by the described air pipe of claim 1 (2).
