Abstract
The utility model belongs to an auxiliary device for bicycle, mainly providing a mini inflating device which is installed on the bicycle and is powered by the rotation of the bicycle. The utility model mainly comprises a cam, a driven rod, an air cylinder piston and an air cylinder. The cam is arranged on the center shaft on another side of a chain disc, and a straight reciprocating motion, that the driven rod drives the piston, is converted by the rotation caused by that the cam is pedaled backward, to charge the air cylinder with air and to inflate the tyre through a guide tube. The utility model has simple structure, easy production, lower cost, convenience and practicality.
Description
The utility model belongs to the bicycle auxiliary device, relates generally to a kind of mini inflatable device that utilizes bicycle self power.
Existing bicycle inflator is more, the gas filled device of installing on traditional inflator pump, the tire that replenishes air pressure is at any time arranged, application number is 85203737 " the miniature S. A. of bike tyre is with the car gas filled device ", adopt the bent type structure of connecting rod crank, piston-cylinder, form by physics modification and small-sized unitized design, need crank, engaged transmission idle wheel in the member, come pressurized air by the transmission of bicycle hinge wheel or chain.Complex structure, member precision height, and want the engaged transmission idle wheel, use inconvenient.
The purpose of this utility model provides a kind of miniature bike gas filled device that carries with car, and it is simple in structure that it is had, the characteristics that are easy to install and use.
Main technical schemes of the present utility model is: it mainly is made of cam, follower lever, cylinder and piston and air tank, cam is installed on the axis of chain drum opposite side, follower lever is connected with cam by the grooved bearing, drive the piston crank motion, air inlet and exhaust valve is set in the air tank, inflates for the air tank admission port to bike tyre by conduit in order to control.
Accompanying drawing provides an embodiment of the present utility model:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is that the utility model combines scheme drawing with axis.
Accompanying drawing 3,4 is the utility model fixed folder structure and scheme of installation.
Accompanying drawing 5 is nut in the utility model, baffle plate and follower lever connection diagram.
In the accompanying drawing: 1, cam, 2, cam hole, 3, the grooved bearing, 4, follower lever, 5, elastic nut, 6, spring stop, 7, spring, 8, compression cylinder, 9, geometrical clamp, 10, piston, 11, air tank, 12, blow off valve; 13, rubber catheter, 14, air suction valve, 15, nut, 16, tingle, 17, check screw, 18, the elastic thread bar.
In conjunction with the accompanying drawings embodiment of the present utility model is described in detail: the utility model is mainly to be made up of cam 1, follower lever 4, compression cylinder 8, piston 10 and air tank 11, its cam is installed on the axis of chain drum opposite side, concrete structure is that the center hole on the cam is enclosed within on the axis, geometrical clamp is fixed on pedal by cam hole 2 with cam and turns, turn rotation with pedal, bicycle is reversed the straight reciprocating motion that motion is converted into follower lever by cam; One end chuck of follower lever 4 has corrugated bearing 3, and corrugated bearing 3 grooves rotate with cam rotation at the cam edge, relies on the application force of spring 7 to be pressed on the cam and unlikely and its disengaging, in order to reduce that follower lever contacts with cam and the friction and wear that produces.Follower lever 4 other ends connect piston 8, promote reciprocating motion of the pistons, compression cylinder utilizes the crank motion pressurized air of piston, be provided with blow off valve 12, air inlet valve 14 in the air tank 11 in order to storing high pressure gas, air inlet valve is closed when piston 10 pressurized airs, blow off valve is opened, and pressurized air is compressed into air tank 11, and air inlet valve 14 is opened when piston 10 backhauls, inspiration gas, blow off valve 12 is closed.Shown in accompanying drawing 3,4: geometrical clamp is made of two intermediate plates and three captive nuts of symmetry, and it is fixed on the position that pedal turns by cam hole 2 with cam and sees accompanying drawing 4, and this gas filled device utilizes geometrical clamp 9 to be packed on the bicycle back vertical tube.
As shown in Figure 5: an end of spring 7 is provided with a spring stop 6, and elastic nut is spun on the elastic thread of spring stop one side, because elastic force effect and follower lever 4 combine, plays the fixedly effect of plate washer position.
This device is installed on the upright beam below the bicycle saddle, bicycle stops during use, with hand or pedal, cam is reversed backward with axis, cam promotes follower lever, piston, air in the compression cylinder, this moment, blow off valve was opened, and air inlet valve is closed, when cam reaches maximum rise, follower lever under gravity and elastic force effect with the cam backhaul, this moment inlet open, exhaust valve closure, and so forth the circulation, with axis, rotatablely moving of cam is converted into follower lever, the straight-line motion of piston, with the air compression in the cylinder, be stored in the gas cylinder, utilize conduit to inflate to bicycle; Inflation finishes, and loosening elastic nut with follower lever and cam disengages, bounces back to cylinder one end and fixes, thus guarantee bicycle pin during riding stare at reverse unaffected.
Claims (4)
1, a kind of bicycle is miniature with the car gas filled device, it is characterized in that: mainly constitute by cam 1, follower lever 4, piston 10, cylinder 8 and air tank 11, cam is installed on the axis of chain drum opposite side, follower lever 4 is connected with cam 1 by grooved bearing 3, do straight reciprocating motion with camming movement, be provided with in the air tank 11 and open and close to air inlet in the air tank and air-breathing row, air inlet valve 12,14 in order to reciprocating motion of the pistons the time.
