Description

Hand pump for bicycle

The utility model relates to the gas filled device of bike tyre, belongs to technical field of traffic transportation.

General Bicycle inflator is made up of cylinder, piston, piston rod, handgrip, air receiver (bag) etc.During use, holding handgrip, the driven plunger up-and-down movement, pressure gas is inflated to bicycle, the very effort that seems, child, the elderly and comrade women use and feel unable to do what one wishes, the inflation difficulty.Existing inflator volume is big, and globality is poor, carries inconvenience with car, and often bicycle tire deficency in the stroke way is difficult to find the inflator inflation, influences stroke, the overslaugh working and learning.

The purpose of this utility model provides a kind of with car inflation easy to carry labour-saving hand-operated bicycle inflator pump.

The purpose of this utility model is achieved in that inflator pump is by shell, binary inflator, blade wheel mechanism, compositions such as chute device.Said shell is made up of main case (19) and cap (1) etc., cap (1) is provided with hinge with main case (19) and is connected, main case (19) is provided with U type geometrical clamp (20), adopt nut (25) to be fixed on the main case, be provided with supporting plate (21) and adapter plate (6) in the main case (19), strap (24) is set on the main case inwall, and supporting plate (21) and adapter plate (6) adopt screw (22) to be connected and fixed with strap (24).Said binary inflator is made up of work inflator (28) and Boost bicycle pump (18) etc., flat crouching is fixed on the supporting plate (21), air intake valve (17) and the valve of giving vent to anger (16) are established in the bottom of work inflator, air intake valve or air inlet pipe (27) are established and give vent to anger valve or freeing pipe (26) in the bottom of Boost bicycle pump, the valve of giving vent to anger (16) of work inflator adopts India rubber tube (23) to be connected with the air intake valve of Boost bicycle pump or air inlet pipe (27), in the work inflator (28) piston (11) is set, piston rod (10), piston rod (10) is fastened on the chute (9).Said chute device is made up of chute (9), directed shifting axle (12) etc.Directed shifting axle (12) is parallel with piston rod (10), and is connected and fixed in vertical state with chute (9).Directed shifting axle (12) is provided with shifting chute or conduit (13), and shifting chute or conduit (13) are fixed on the supporting plate (21), and directed shifting axle is arranged in shifting chute or the conduit.Said blade wheel mechanism is made up of blade wheel (7), rocking handle axle sleeve (3), crank shaft (4), connecting rod (2), square head shaft (5), roll shaft (8) etc.; crank shaft (4) is hinged with connecting rod (2); rocking handle axle sleeve (3) is sleeved on the crank shaft (4); connecting rod (2) is fastened on the adapter plate (6) by square head shaft (5) with blade wheel (7); connecting rod (2) places the top of adapter plate (6); blade wheel (7) places the below of adapter plate (6); roll shaft (8) is arranged on the work wheel rim, and an end of roll shaft places in the chute (9).

The utility model is simple and reasonable, and cost is low, is convenient to be installed on the bicycle, and is easy to carry, inflates laborsaving.Use the utility model, open cap (1) earlier, pull out rocking handle again, hand rocking handle, blade wheel (7) rotation, roll shaft (8) drives chute (9) and drives piston (11) crank motion in the work inflator on the piston rod, produces high pressure draft and enters in the Boost bicycle pump through the valve of giving vent to anger (16), from give vent to anger valve or the freeing pipe (26) of Boost bicycle pump cycle tyre is inflated.

Accompanying drawing 1 is a main TV structure scheme drawing of the present utility model, give vent to anger valve, 19 main cases, 20U type geometrical clamp, 28 work inflators of 1 cap, 2 connecting rods, 3 rocking handle axle sleeves, 4 crank shafts, 5 square head shafts, 6 adapter plates, 7 blade wheels, 8 roll shafts, 9 chutes, 10 piston rods, 11 pistons, 12 directed shifting axles, 13 shifting chutes or conduit, 14 upper end covers, 15 bottom end covers, 16 among the figure.

Accompanying drawing 2 is the utility model plan structure scheme drawing, 2 connecting rods, 3 rocking handle axle sleeves, 4 crank shafts, 5 square head shafts, 6 adapter plates, 7 blade wheels among the figure, 9 chutes, 12 directed shifting axles, 13 shifting chutes or conduit, 14 upper end covers, 15 bottom end covers, 16 give vent to anger valve, 17 air intake valves, 18 Boost bicycle pumps, 19 main cases, 20U type geometrical clamp, 21 supporting plates, 22 screws, 23 India rubber tubes, 24 straps, 25 nuts, 26 give vent to anger valve or freeing pipe, 27 air intake valves or air inlet pipe, 28 work inflators.

Narrate a case study on implementation of the present utility model with reference to the accompanying drawings.

The bobbin upper and lower end of binary inflator is provided with upper end cover (14) and bottom end cover (15) respectively, the piston (11) of work inflator adopts rubber cup, piston rod (10), directed shifting axle (12) are welded to connect with chute (9) respectively, India rubber tube (23) is arranged on outside the shell of main case (19), is provided with the axle sleeve of flange between square head shaft (5) and the adapter plate (6).
