Abstract

The utility model relates to a walking cycle, which can be used for the uneven road of mountain area. A slide bar with a rack bar which can slide up and down is arranged in a vertical guide cylinder; the top end of the slide bar with the rack bar is provided with a pedal; the lower section of the right side of the slide bar with the rack bar is provided with a straight rack bar; a helical spring is arranged between the intermediate plate of the vertical guide cylinder and the top pedal of the slide bar with the rack bar; a wheel carrier is pivoted with a horizontal rotating shaft; the horizontal rotating shaft is fixed with a ratchet wheel; a gear ring joggled with the straight rack bar is sheathed on the ratchet wheel. The utility model can enhance walking speed.

Description

Walking vehicle

The utility model relates to a kind of sleigh, is particularly suited on the irregular road in mountain area the people and wears and carry the walking vehicle that slides.

At present, common roller skate is to slide on smooth road for the teenager, and the exercise of taking exercises is harder for sliding for a long time on out-of-flatness and the road, and sole and anklebone can feel sick, and is poor for applicability.

In view of this, the purpose of this utility model provides a kind of walking vehicle, wears to be loaded under the sole, can quicken the speed that slides, and pin is subject to damage not again.

The purpose of this utility model is achieved in that a kind of walking vehicle comprises trailing wheel, front-wheel, wheel carrier, on the wheel carrier between trailing wheel and the front-wheel, be provided with the vertical guide rail tube, in this vertical guide rail tube, be provided with can upper and lower slip band tooth bar slide bar, between the top pedal of being with the tooth bar slide bar and vertical guide rail tube intermediate plate, be provided with helical spring, on wheel carrier, articulate a horizontal rotating shaft, a fixedly connected ratchet and a gear in this rotating shaft, the gear ring that this ratchet upper sliding sleeve is meshed with spur rack is fixed a rear axle gear on hind axle.

Be provided with the two cluster gears that are meshed between the gear that above-mentioned rear axle gear and level are changeed.

Owing to adopt such scheme, accelerate the speed of walking greatly, simple in structure.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1, the utility model exemplary embodiments schematic diagram;

Fig. 2, the utility model exemplary embodiments schematic diagram;

Among the figure: 1. vertical guide rail tube 2. trailing wheels 21. rear wheel gears 3. front-wheels 4. band tooth bar slide bars 41. top pedals 42. spur racks 5. helical springs 6. horizontally rotate 7. pairs of cluster gear 8. wheel carriers of 61. gear rings, 62. ratchets, 63. ratchets, 64. gears

Present embodiment mainly comprises vertical guide rail tube 1, trailing wheel 2, front-wheel 3, band tooth bar slide bar 4, helical spring 5, horizontal rotating shaft 6 and wheel carrier 8, as shown in Figure 1, 2, and wherein:

Vertical guide rail tube 1 is connected the vertical tube on the wheel carrier 8 between trailing wheel 2 and the front-wheel 3, also is provided with brake gear (belonging to existing technology) in addition.

Two trailing wheels 2 are connected transverse axis two ends, and this transverse axis supports (with bearing) to belong to prior art on 2 wheel carriers 8; Fixedly connected two rear axle gears 21 on the connection transverse axis of this two trailing wheel 2.

Front-wheel 3 (one or two) articulates with the support body front axle that is connected transverse axis of trailing wheel 2, belongs to prior art.

Band tooth bar slide bar 4 its tops have top pedal 41, and the right side hypomere has spur rack 42, and the epimere of this band tooth bar slide bar 4 and vertical guide rail tube 1 are slidingly matched and limit its rotation.

Helical spring 5 is supported in respectively between the intermediate plate of the top pedal 41 of two band tooth bar slide bars 4 and vertical guide rail tube 1.

Horizontal rotating shaft 6 is articulated on the rear wheel frame 22, fixed ratchet wheel 62 and gear 64 on it, slip socket gear ring 61 and hinged and ratchet 62 cooperates on gear ring 61 ratchet 63 (also having spring to be connected) on the ratchet 62.

Two cluster gears 7 strengthen the raising speed ratio in gear 64 and rear axle gear 21 engagements, trailing wheel 2 is rolled accelerate.

The operation principle of present embodiment:

When a pin is stepped on top pedal 41 downwards, compression helical spring 5, band tooth bar slide bar 4 is to lower slider, its spur rack 42 drives gear ring 61 and rotates counterclockwise, driving ratchet 62 through ratchet 63 rotates, be that horizontal rotating shaft 6 rotates, the gear 64 on it drives two cluster gears 7, rear axle gear 21, trailing wheel 2 rollings, and car rolls forward; When pin upwards lifted, under the effect of helical spring 5, band tooth bar slide bar 4 upwards slided, and its spur rack 42 drives gear ring 61 and clockwise rotates, and ratchet 62 can not drive ratchet 62, and horizontal rotating shaft 6 does not just rotate.

Claims

1, a kind of walking vehicle, comprise trailing wheel (2), front-wheel (3), wheel carrier (8), it is characterized in that: on the wheel carrier (8) between trailing wheel (2) and the front-wheel (3), be provided with vertical guide rail tube (1), in this vertical guide rail tube (1), be provided with and go up, the band tooth bar slide bar (4) of lower slider, between the top pedal (41) of being with tooth bar slide bar (4) and vertical guide rail tube (1) intermediate plate, be provided with helical spring (5), go up pivot joint one horizontal rotating shaft (6) at wheel carrier (8), a fixedly connected ratchet (62) and a gear (64) are gone up in this rotating shaft (6), the gear ring (61) that this ratchet (62) upper sliding sleeve is meshed with spur rack (42) is fixed a rear axle gear (21) on trailing wheel (2) axle.

2, by the described walking vehicle of claim 1, it is characterized in that: be provided with the two cluster gears (7) that are meshed between the gear (64) of above-mentioned rear axle gear (21) and level commentaries on classics (6).
