Abstract
The utility model provides a kind of new bicycle accelerator.It is with the bicycle middle shaft both sides respectively the pedal leg of load be designed to connect the sliding extension formula pedal leg that sliding connecting rod is formed by frame linking, on the sliding shoe of the sliding connecting rod of pedal leg, be fixed with bearing, the bearing running-fit is connecting the slot type cam, be fitted with the vehicle frame connecting plate that is fixed in bicycle in order to connect on the slot type cam periphery, the bicycle accelerator of the set pattern sliding extension formula pedal leg of being formed.Its novel structure, design innovation, equipped simple and easy, ride with laborsaving fast, easy to use, be a kind of later-model bicycle accelerator.
Description
Technical field
The utility model relates to a kind of parts of bicycle, especially a kind of bicycle accelerator.
Background technology
Bicycle is the main vehicle that people use always.Along with the raising day by day of living standards of the people, also more and more higher to the technical requirements of bicycle.In known technology, existing bicycle accelerator mainly is by being installed in the tower wheel disc and the different-diameter proportioning conversion that is loaded on flywheel on the rear axle on the axis, improving the speed of bicycle.But it is equipped complicated, easy jam chain during the conversion position of wheel, and complex operation brings inconvenience to use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel structure, and is equipped simple and easy, laborsaving fast, rides and uses bicycle accelerator easily.
The technical scheme that its technical matters that solves the utility model adopts is: the pedal leg of bicycle is designed to sliding extension formula pedal leg, on the sliding shoe of pedal leg, be fixed with bearing, bearing is connecting the slot type cam, the pedal leg is slided along the chute set pattern of cam by its bearing, realize the rule elongation and the retraction of pedal leg, be fitted with on the slot type cam periphery and win in succession, be fixed on the vehicle frame of bicycle, the bicycle accelerator of the set pattern sliding extension formula pedal leg that consists of in order to connect.During use, with sliding extension formula pedal leg of the present utility model load on bicycle middle shaft, load step tread plate on the slide link head of pedal leg, the slot type cam is fixed on the vehicle frame of bicycle, the big plush copper end of cam makes the pedal leg when pedaling forward towards the bicycle front portion, and its connecting shaft holds running-fit and connecting the slot type cam and slide to big plush copper end, with the elongation of pedal leg, laborsaving acceleration.
Because technique scheme has been adopted in the utility model design, show that it has novel structure through test for several times is on probation again, design innovation, equipped simple and easy, to ride with laborsaving fast, advantage such as easy to use is a kind of later-model bicycle accelerator.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the concrete structure diagrammatic sketch of the utility model embodiment.
Fig. 2 is the left view of Fig. 1 embodiment.
Reference numeral: 1 cam, 2 connecting plates, 3 pedal leg frame linkings, 4 sliding connecting rods, 5 bearings, 6 bearing connecting shafts, 7 axis, 8 step tread plates, 9 bearings.
The specific embodiment
As accompanying drawing 1, embodiment shown in Figure 2, the utility model is that the pedal leg of bicycle middle shaft 7 both sides difference load (also being pedal connecting rod) is designed to connect the sliding extension formula pedal leg that sliding connecting rod 4 is formed by frame linking 3, the sliding connecting rod 4 of pedal leg is made up of the sliding shoe coupler link, on the sliding shoe of sliding connecting rod 4, be fixed with antifriction-bearing box 5, bearing 5 each running-fit are connecting the chute of slot type cam 1 (totally 2 on cam), driving the pedal leg by bearing slides along the chute set pattern of cam and clocklike extends and bounce back, be fitted with on the periphery of slot type cam 1 in order to what connect the vehicle frame be fixed in bicycle and win 2 in succession, the bicycle accelerator of the set pattern sliding extension pedal leg of being formed.
Be equiped with antifriction-bearing box 9 running-fits on sliding shoe two lateral bodys of the sliding connecting rod 4 of the telescopic pedal leg of the utility model respectively and connect the slide groove that makes on frame linking 3 inwalls; Or the sliding shoe both sides that will slide connecting rod 4 are made as the slide groove running-fit that makes on slide rail and its frame linking 3 inwalls and are connected.
Two slot type cams of the present utility model 1 are best to be connected relatively for notch, does not does not wear and tear and stain trouser legs in order that ride the time spent outwardly in its baseplane.Being connected accordingly, connection bearing 5 connecting shafts 6 are inflection cambered axle (see figure 2) on the sliding connecting rod 4 of pedal leg of cam path.Certainly, also can be that two slot type cams 1 are notch mouth connection outwardly in opposite directions, the bearing connecting shaft of the sliding connecting rod of the pedal leg of the cam path that is connected accordingly is a d-axis; Or the notch of two slot type cams 1 connects in the same direction.
Referring to accompanying drawing 1 embodiment, the frame linking axle sleeve that the telescopic pedal leg of the utility model connects the sliding connecting rod 4 of axis 7 is the axle sleeve of square hole, or the axle sleeve of flat round hole; Corresponding institute bonded assembly axis 7 is the axis of square shaft head, or the axis of oblate spindle nose.
