Abstract

The utility model discloses a tool instead of walk. The tool is mainly composed of an upper bicycle body, a lower bicycle body, a connecting rod, a gearbox, braking bodies, a front wheel and a back wheel, wherein, the connecting rod can drive a ratchet wheel to rotate via the reciprocating movement of the upper bicycle body, a force is orderly transmitted to gears in the gearbox, the speed of the force is increased or reduced, a thrust force is generated by the friction of the back wheel and the ground, and thus a rider can move ahead at a certain speed. The back parts of the bicycle bodies are provided with the braking bodies to obtain the aim of reducing the speed or stopping a bicycle. The functions of the bicycle, roller skates and shoes can be presented via the use of the utility model, and the utility model has the advantages of convenience, quickness, labor saving, long service life and low manufacturing cost.

Description

Three usefulness are footwear voluntarily

The utility model relates to a kind of footwear, exactly is a kind of footwear voluntarily.

The purpose of this utility model is both to have can be used as travel kit for people provide a kind of, but double as athletic equipment footwear voluntarily again.

The purpose of this utility model is achieved in that it is by upper body 2, lower body 6, gearbox 22, front-wheel 3, trailing wheel 21 is formed, and these upper body 2 front ends are hinged through front axle 4 and lower body 6, its postmedian downside articulated linkage 8, these connecting rod 8 other ends and Rocker arm 47 are hinged; Rocker arm 47 connects firmly with ratchet shaft 36, install a ratchet 13 on it balladeur trains 34 are installed, these gear 34 corresponding site hinged claw 12; the ratchet corresponding position is equipped with leaf spring 12; this ratchet, and ratchet matches, described Fig. 2 middle gear 34 and figure two middle gear axles 37; 39; 41; gear transmission successively on 43; axle 43 gears are meshed with gear on spools 46, and trailing wheel 21 is equipped with at these two ends.

Compared with the prior art, have simple in structurely after the utility model is realized, volume is little, and is in light weight, safe in utilization, and long service life, and cost is low.

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

Fig. 1 is a structural representation of the present utility model;

Fig. 2 overlooks the expansion schematic diagram for the utility model gearbox.

As shown in the figure: the utility model is by upper body 2, lower body 6, front-wheel 3, trailing wheel 21, gearbox 22, brake body 24 compositions such as grade.Wherein upper body (pedal) 2 is a flute profile batten, and postmedian has a slit, and slide mass 11 is housed in this slit, and heel shape spring bearer plate is housed on the slide mass, and this slide mass front end hangs with extension spring 10, and slide mass can be slided front and back with pin type difference; Described upper body 2 is connected with lower body by front axle 4; This upper body front end is equipped with starter 1 and movable pressure foot; Lower body 6 is for this car owner wants supporting construction, and its front end is interconnected by front axle 4 and upper body 2, and rear portion and gearbox 22 connect firmly; Tail end connects brake body 24; Described gearbox 22 is by parts such as ratchets 12,13,14,15, Rocker arm 47, and connecting rod 8, gear on the gear shaft 48,49,50 and output shaft 46 are formed.Export 46 two ends trailing wheel is housed.Described connecting rod 8 upper shafts 7 link with upper body postmedian respective link seat; The lower end connects through the rocking arm of pitman shaft with ratchet shaft 36 1 ends; Described ratchet 12 is for dividing body structure: ratchet 12 is an one with ratchet shaft 36, and Rocker arm 47 connects firmly with ratchet shaft by square hole or keyway etc.; Ratchet one end is equipped with gear 34, and ratchet 12 is equipped with in this gear relevant position, and leaf spring 14 is fixing by screw 15; Gears engaged on described gear 34 and the gear shaft 37; This shaft gear is meshed with gear on the gear shaft 39; This is meshed with gear on the gear shaft 41 again; Gear on this gear shaft again with hind axle 46 on the axle tooth be meshed; Bearing all is equipped with at each gear shaft two ends.Gearbox is made up of casing 32 and case lid 33, and four jiaos are equipped with screw 16.

Described brake body is the split bathtub construction, and slide plate is equipped with on its top, connects with lower body through screw 23; Dog point 31 is equipped with in the bottom, the middle part is shaped on spring eye, spring 27 is housed respectively, spring base 28, axis hole is left in this spring base bottom, brake wheel shaft 29 is housed, brake wheel is equipped with at the wheel shaft two ends to be changeed together with axle, and this central authorities' one sidetracking has through hole, fixedly brake cable, the brake cable other end enters in gearbox rear end lower one side through hole and fixes with band-type brake 19 lower ends, and band-type brake 19 upper ends are fixing with screw 20.Taillight 26 is equipped with at the brake body rear portion.

Certainly, the utility model also can be provided with following locking device and gear, and this handle links to each other with lower body 6 with screw, and spring is equipped with at its middle part, and the spring other end also is articulated on the lower body 6, and reach drives pull bar makes the rear mudguard reach embrace trailing wheel; After move dashboard opened as dashboard.Described gear is installed in this casing outer upper front end of gearbox 22 outsides and leaves two apertures, and two speed change pull bars stretch into from here and are connected on the gear shift fork, and handle is equipped with in the pull bar outer end, can realize the level Four speed change.Fixing card 5 is equipped with at described lower body 6 middle parts, so that fix or open upper body.

Upper body 2 in the utility model, lower body 6, gearbox 22 housings, front and back wheel 3,21, each gear in the gearbox 22, connecting rod 8, axle 7,9 is iron, processing voluntarily, brake body 24 and brake axle 29 are taken turns 30 and are plastic products, processing voluntarily, tire is one deck TR thin rubber, inchoative aspect 1, and dog point 31 is rubber, self-control, each bearing and spring are the outsourcing standard component, after each parts is got all the ready, by the figure assembling, through after the assay was approved, can put in storage.
