Abstract

The present invention discloses an improved self-running slide plate whose car body can be contracted. It is characterized by that a rear axle is fixed in the inner side of two retractable slipways, arear plate is pivoted on the middle portion of said rear axle, two rear wheels are respectively placed on two ends of said rear axle, left and right two sides of said rear plate are respectively extended downwards, a brake is placed over the rear wheel hub. Said structure is simple, and its cost is low.

Description

The modified body retractable self-moving slide board

Technical field:

The present invention relates to the wheeled vehicle that a kind of rider drives, be specifically related to a kind of slide plate, particularly a kind of self-moving slide board with stretching drive mechanism is applicable to nonirrigated farmland roller-skating motion.

Background technology:

Existing slide plate is provided with four pulleys below a substrate forms, and the user must drive with a feet step on the ground.The inventor improves prior art, and successively knows that to state office has proposed four patent applications, and publication number is respectively: CN1600396, CN1600632, CN1736524 and CN1749099.The common technical characterictic of described four patent applications is, two sections were fixed on the slideway before and after the plate face was divided into, and front and back two plate faces have a reset tension spring, and establish a mono-directional overrun clutch respectively in two trailing wheels.Therefore as seen, mono-directional overrun clutch is one of common and requisite technical characterictic of these four described technical schemes of patent application.But this freewheel clutch complex structure, required precision height, manufacturing cost height.

Summary of the invention:

Technical problem to be solved by this invention is to simplify the body retractable self-moving slide board structure.

The scheme that the present invention solves the problems of the technologies described above is:

A kind of modified body retractable self-moving slide board, comprise front face and back plate face, it is characterized in that: have one to be " recessed " font back axle, trailing wheel is located at this back axle left and right sides, extend two parallel risers in the back axle vertically upward, the outside of two risers is fixed with the internal layer grooved section bar of two telescopic chute respectively; Back plate face is articulated in the head of two risers of back axle by downward extension two lugs, and the left and right sides of back plate face is extended the top of a damper brake to the wheel rim of trailing wheel respectively downwards.

Technical scheme of the present invention, when the plate face leans forward it after the sporter is pedaled with rear treadle, described damper brake can push the outer rim of trailing wheel, the trailing wheel stall, rear riding force must be delivered on the front-wheel by the forward foot in a step, and the elastic force that overcomes extension spring is stretched two telescopic chute, in case remove the rear riding force on the plate face of back, damper brake resets, and the trailing wheel braking is removed, and extension spring just spurs and moves before the back plate is worn trend.Repeat above-mentioned action, self-moving slide board one of the present invention is stretched one and is contracted, and car connects the people and travels forward together.

For described back plate face can be returned after rear riding force is cancelled automatically, technique scheme is divided into a guide rod at back plate face, and this guide rod extension downwards passes through dividing plate set on the back axle, a sheathed compression spring on the end.When inclining in face of the plate of described back, this compression spring is compressed, in case rear riding force is cancelled, the compression spring just makes back plate face automatically reset rapidly.

Damper brake of the present invention is made of the lock head of a vertical rod and hinged this vertical rod lower end.

The present invention uses described damper brake to replace the mono-directional overrun clutch of prior art, and the structure of product is simplified greatly, and cost obviously reduces, and has also eliminated the frictional dissipation that mono-directional overrun clutch inside is produced simultaneously.

Description of drawings

Fig. 1, Fig. 2 and Fig. 3 are the structural representation of a kind of specific embodiment of the present invention, and wherein Fig. 1 is a front view, and Fig. 2 upward view, Fig. 3 are that the A of Fig. 1 is to enlarged drawing.

Fig. 4 is the structural representation of another kind of specific embodiment of the present invention.

The specific embodiment

Below in conjunction with drawings and Examples the present invention is explained in further detail, but the present invention is not limited by described embodiment.

Example 1

What Fig. 1, Fig. 2 and Fig. 3 were shown is a kind of slide plate that adopts technical scheme design of the present invention.

Referring to Fig. 1, Fig. 2 Fig. 3, two telescopic chute 3 are known configurations (specifically referring to CN1736524 or CN1749099).

Referring to Fig. 3, described back axle 1 is " recessed " font, and trailing wheel 2 is located at its left and right sides; Extend two parallel riser 1A in the back axle 1 of " recessed " font vertically upward, the internal layer grooved section bar of two telescopic chute 3 is separately fixed at the outside of riser 1A; Described back plate face 4 extends two lugs 5 downwards, and is articulated in the head of two riser 1A respectively.

Referring to Fig. 1 and Fig. 3, the left and right sides of back plate face 4 is extended the top of a damper brake 6 to the wheel rim of trailing wheel 2 respectively downwards.Described damper brake 6 is made of the lock head 6B of a vertical rod 6A and hinged this vertical rod 6A lower end.

Referring to Fig. 1, Fig. 2 and Fig. 3, back plate face 4 is divided into a guide rod 7, and dividing plate 1B set on the back axle 1 is passed through in this guide rod 7 extension downwards, a sheathed compression spring 8 on the end.

Referring to Fig. 1, Fig. 2 and Fig. 3, following vertically being arranged with between two angle steel, 10, two angle steel 10 of front face 9 is provided with a plate 11, and two angle steel 10 are fused to be stuck on two telescopic chute 3 to be connected with its outer grooved section bar.

Referring to Fig. 1 and Fig. 2, front face 9 is bearing on the connecting plate 11 by rolling bearing, and is free to rotate, and concrete supporting and direction control scheme is that the application for a patent for invention of CN1736524 is identical with publication number all.

Referring to Fig. 1 and Fig. 2, extension spring 12 is the requisite parts of the present invention, and its two is connected to front face 9 and back plate face 4 times, and concrete method of attachment and publication number are that the application for a patent for invention of CN1736524 or CN1749099 is identical.After telescopic chute 3 was stretched under the effect of external force, in case external force is cancelled, telescopic chute 3 just can easily be withdrawn and be resetted under the effect of extension spring 12.

Implementation method beyond present embodiment is above-mentioned is utilized prior art and is implemented to get final product with reference to Fig. 1, Fig. 2 and Fig. 3.

Example 2

What Fig. 4 was shown is a kind of slide plate (event also is referred to as scooter) with tap 13 that adopts technical scheme design of the present invention.The plate face of the described scooter of present embodiment is made up of plate face 9 and back plate face 4, and extension spring 12 two are connected to front face 9 and back plate face 4 times.The boundary in the middle of front face 9 and the back plate face 4 of the described scooter of present embodiment, first half, promptly the connected mode of front face 9 and two telescopic chute 3 and leading 13 is that the application for a patent for invention of CN1736524 is identical with publication number all; Latter half is identical with example 1, implements to get final product with reference to Fig. 1, Fig. 2 and Fig. 3.
