Description

Step on drive mechanism before the scooter

Technical field

The utility model relates to a kind of driving drive mechanism of scooter, steps on drive mechanism before especially a kind of scooter.

Background technology

Current commonly used scooter structure generally all is to set firmly a pedal on the seat stepping on, and establishes car head in the pedal front end, be connected with handle tube in the first top of car, front-wheel is then established in the bottom, and establishes trailing wheel in stepping on a tail end, and then forms a complete scooter, when this scooter uses, user's one pin is trampled in the pedal of stepping on the seat, and two hold the handle two ends that are held on the handle tube, step on ground with another pedal again, by reaction force, scooter is advanced from ground.Yet this slide plate can only be pedaled for the user and step on the ground motion of advancing, and can not allow the user trample the usefulness of the motion of advancing.

Summary of the invention

Main purpose of the present utility model is to provide a kind of tool to trample advances and steps on drive mechanism before function can improve movement effects and use the scooter of excitement.

For the utility model that achieves the above object adopts following technical scheme: step on drive mechanism before the scooter and step on a leading portion in one and be connected with car head, the first top of this car is connected with handle tube, front-wheel is then established in the bottom, establish trailing wheel and step on base rear end, the described treadle that is pivoted on the seat of stepping on, stretching under this treadle has a drive rod, this drive rod tool circular arc limit, this circular arc limit is provided with double wedge, and establish a fluted disc that cooperates with the double wedge of this drive rod on the seat in stepping on, and being installed with a head sprocket on this fluted disc is coaxial, this head sprocket links to each other with an auxiliary chain wheel through chain, set firmly intermediate chain wheel on this auxiliary chain wheel is coaxial, this intermediate chain wheel through chain and be installed in hind axle on after sprocket wheel link to each other.

The utility model compared with prior art can allow the user trample bar and scooter is advanced by pin, reaches the effect that improves movement effects and use excitement.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1 and Figure 2, basic structure of the present utility model lies in a leading portion of stepping on seat 10 and is connected with car head 20, and first 20 tops of this car are connected with handle tube 21, and front-wheel 22 is then established in the bottom, establishes trailing wheel 30 and step on seat 10 rear ends.Stepping on seat is pivoted on 10 and one has set up back-moving spring mechanism treadle 11, this treadle is stretched for 11 times a drive rod 110, these drive rod 110 tool circular arc limits, this circular arc limit is provided with double wedge 111, and establish a fluted disc 12 that cooperates with the double wedge 111 of this drive rod 110 on 10 in stepping on seat, set firmly a head sprocket 13 on this fluted disc 12 is coaxial, this head sprocket 13 through chain 14 and with an auxiliary chain wheel 15 interlocks, set firmly intermediate chain wheel 16 on this auxiliary chain wheel 15 is coaxial, this intermediate chain wheel 16 through chain 17 and be installed on the hind axle after sprocket wheel 18 interlocks, trample bar 11 and scooter advanced with pin.

As Fig. 3, shown in Figure 4, the utility model in use, user's two hands grip handle, and a pin trampled in stepping on seat 10 the pedal 19, constantly trample treadle 11 (the back-moving spring mechanism on the treadle 11 can rebound treadle 11 can trample the position) with another pin again, this treadle 11 is when lower swing, the double wedge 111 on the drive rod 110 circular arc limits of this treadle 11 is because of meshing with fluted disc 12, so can order about fluted disc 12 rotations, these fluted disc 12 coaxial head sprockets 13 are rotation thereupon also, drive auxiliary chain wheel 15 again rotates through chain 14 transmissions, these auxiliary chain wheel 15 coaxial intermediate chain wheels 16 also rotate thereupon, sprocket wheel 18 rotations through chain 17 and after making again, and then drive trailing wheel 30 lift-over forward, order about the effect that slide plate is advanced and reach.

Can conclude by said structure and the utlity model has following advantage:

1. make scooter produce new motion morphology; It combines by the collocation of members such as sprocket wheel between treadle major-minor sprocket wheel and chain, constitutes the transmission mechanism of single pin override type, makes scooter produce new motor function.

2. the use phychology that meets user's seeking change and innovation; It improves at mechanism of scooter, has changed the occupation mode of scooter commonly used, allow the user many again a kind of new selection, cater to the user demand of user's seeking change and innovation.

3. back and forth trample motion by single pin, can promote sports performance efficiency and motion interest.

Claims (1)

1. step on drive mechanism before a scooter, step on a leading portion in one and be connected with car head, the first top of this car is connected with handle tube, front-wheel is then established in the bottom, establish trailing wheel and step on base rear end, it is characterized in that: the described treadle that is pivoted on the seat of stepping on, stretching under this treadle has a drive rod, this drive rod tool circular arc limit, this circular arc limit is provided with double wedge, and establishes a fluted disc that cooperates with the double wedge of this drive rod on the seat in stepping on, be installed with a head sprocket on this fluted disc is coaxial, this head sprocket links to each other with an auxiliary chain wheel through chain, sets firmly intermediate chain wheel on this auxiliary chain wheel is coaxial, this intermediate chain wheel through chain and be installed in hind axle on after sprocket wheel link to each other.
