Description

The bicycle of band gas filled device

The utility model belongs to a kind of bicycle that has gas filled device.

Existing bicycle all uses the inflated rubber tire, can produce gas leakage unavoidably in the process of riding, and is not with inflatable tool because of bicycle, brings very inconveniently to the rider, even has influence on work, studying and living.Demand according to people, inflatable tool is carried at present existing people's proposition with car on bicycle technical scheme, the one, inflatable tool (as Floor Pump) directly is placed on the vehicle frame, the shortcoming of this scheme is can influence bicycle whole outer existing, and hinders and ride; The 2nd, the saddletree pipe of bicycle saddle below is directly made Inflator mounted on bicycle, but this scheme is higher to the technical requirements of vehicle frame making, productive costs increases big, and can not reach desirable charge air because of piston stroke is limited, and promotion and implementation are difficulty relatively.

The purpose of this utility model is a kind of later-model bicycle that has gas filled device of design, it not only has the various structures and the performance of existing bicycle, and can use easily and carry gas filled device with car tire is put on the air, satisfy bicycle user's needs.

The purpose of this utility model is finished by the following technical programs:

A kind of bicycle with gas filled device, be made of bicycle and additional gas filled device, the saddle fall way that it is characterized in that bicycle is the cylindrical shell of inflator, and cylindrical shell inserts in the saddletree pipe of saddle below, at cylindrical shell top fixed installation saddle base plate and saddle, inflator handle places in the saddle; The inflation sebific duct is drawn from the bottom tapping of saddletree pipe.

The utility model also has following technical characterictic:

Front end at inflator is connected with the gas tank of being with check valve, and the spool bore of non return valve is built-in with steel ball and spring.

Gas tank places the bottom of bicycle saddletree pipe, and the inflation sebific duct of inflator is connected with gas tank by check valve.

The handle of inflator is to be made of fixed handle and flexible handle.

The saddle front end is connected with pin-and-hole on the saddle base plate by latch, and the saddle rear portion links to each other with the saddle base plate by movable pin.

Bicycle according to the band gas filled device that the utility model proposes, made substantial improvement at the deficiencies in the prior art, it not only can have the various architectural features and the performance of existing bicycle, and can use easily and carry gas filled device with car and at any time tire is put on the air, satisfied bicycle user's needs, convenience is provided.Compared with prior art, this gas filled device does not influence the bicycle outward appearance, and production and processing technology is simple, and productive costs is low, and mounting or dismounting, easy to maintenance are promoted easily and implemented, renovating and perfectly more provide a kind of feasible technical scheme for bicycle.

Fig. 1 is the partial structure scheme drawing of one of the utility model embodiment;

Fig. 2 is the gas tank structural representation of band check valve;

Fig. 3 is two the partial structure scheme drawing of embodiment;

Fig. 4 is three the partial structure scheme drawing of embodiment.

The utility model will be further described according to accompanying drawing below:

Accompanying drawing is an example with 24 ' 4401 type horizontal bar bicycles, only draws vehicle frame and saddle partly, and all the other of bicycle are partly all same as the prior art, the Therefore, omited.

Shown in Fig. 1, bicycle is with the cylindrical shell of inflator 6 fall way as saddle, cylindrical shell is inserted in the saddletree pipe 7 of saddle 11 belows, upper end at the saddletree pipe is shaped on opening, saddle base plate 9 and saddle 11 are fixed on the top of cylindrical shell, the height of saddle is regulated and is fixed and finish by the fixed card 8 of saddletree pipe 7 tops, and the processing of appearance machinery annular knurl can be adopted in air cylinder body and saddletree pipe connection place, guarantees that it connects firmly.The handle of inflator 6 places in the saddle, handle adopts drawing, form by 14 liang of parts of flexible handle 12 and fixed handle suit, flexible handle adopts hollow tubular, the corresponding slotted eye that has in below with the inflator pitch brace, flexible handle can be enclosed within on the fixed handle arbitrarily stretch or draw in, the flexible handle below also is provided with a hook, is used for fixing and prevents that handle from swinging in saddle.The saddle front end is connected with pin-and-hole on the saddle base plate 9 by latch 13, passes the pin-and-hole locking with a stop pin again.The saddle rear portion links to each other with saddle base plate 9 with movable pin 10 by spring, and movable pin 10 can overturn saddle to the vehicle frame rear.The tube of inflator does not have base in an end, adopts negative thread or solder up, and inflation sebific duct 4 is connected with the tracheae coupling head at the tube end, draws from the bottom tapping of saddletree pipe 7 again, passes the below of axis 5, and the card 2 that is fixed along the outside of vehicle frame 3 is fixing, and 1 is to inflate to press from both sides among the figure.

Install the structure situation of the gas tank 18 of band check valve 19 shown in Fig. 2 additional at the front end of inflator 6.Inflator, check valve, gas tank are connected as a single entity by screw thread respectively, spool bore at check valve 19 is built-in with a steel ball 15, the below of steel ball is spring 16 supports, again with plug 17 encapsulation, when producing air pressure in the inflator 6, air-flow compressing steel ball, spring shrinks downwards, the centre hole that air-flow passes steel ball, spring and plug enters gas tank, tracheae coupling head 20 from the gas tank other end enters inflation sebific duct 4 again, increase this stage arrangement, inflator air pressure to tire when putting on the air is increased, charge operation is more laborsaving.

Fig. 3 illustrates the inflator 6 that has installed gas tank additional and is installed on example in the bicycle saddletree pipe, and is identical among all the other structures partly and Fig. 1.

Fig. 4 illustrates an example of inflator 6 and gas tank 18 employing separate type, gas tank 18 is fixedly installed in the bottom of bicycle saddletree pipe 7, the inflation sebific duct 4 of inflator is connected to earlier on the check valve 19 that is located at gas tank top, draws from the tracheae coupling head of gas tank below again.

Above-mentioned three kinds of forms all are applicable to the bicycle of existing all kinds, specification.

During use, earlier the inflation sebific duct is taken off, it is fixing on air faucet of tire to inflate folder 1, pulls up the latch of movable saddle 11, the upset saddle, and the pulling inflator handle can put on the air.
