Description

Self-moving slide board

Technical field:

The utility model relates to a kind of slide plate, and particularly a kind of self-moving slide board with transmission mechanism is applicable to nonirrigated farmland roller-skating motion.

Background technology:

Common slide plate mainly is front and back wheel to be set at two of pedal constitute.The walking movement person of this common slide plate must stand on the pedal by a pin, and the another pin is ceaselessly pedaled and stepped on ground and could drive slide plate and advance, and can't realize that the people drives to advance all the time on slide plate.

In order to solve the problem voluntarily of slide plate, the dealer has disclosed the technical scheme that differs from one another.(notification number is a kind of " pull bar slide plate " utility model patent of wherein comparatively outstanding is State Intellectual Property Office's Granted publication on June 18th, 2003: 2555892), the disclosed technical scheme of this utility model patent is set up such transmission mechanism on common cunning: the sprocket wheel (being described flywheel) of establishing a band mono-directional overrun clutch on hind axle, one on a chain that is serially connected with spring is tied up under the pedal, after walking around intermeshing sprocket wheel, the other end ties up to the end that the rocking bar (described pull bar) that is articulated on the pedal extends to the pedal bottom.Stand on the pedal with the person, shake the handle that bar extends to pedal top, just drive trailing wheel by the sprocket wheel of chain, band mono-directional overrun clutch and actuation mechanism that spring is formed and drive to advance with hand.This shows that this utility model described " pull bar slide plate " has no difference with common manual conveyance vehicle, has lost the intention of slide plate itself fully.Next is the no transfer of this utility model described " pull bar slide plate ", and slide plate can only rectilinear motion.

State Intellectual Property Office in October 24 calendar year 2001 Granted publication than the utility model patent of the self sliding board car of tool intention, Granted publication number is: 2455307.This utility model patent, the pedal of common slide plate is modified into the latch plate of arch, between rear axle and trailing wheel, increase simultaneously by an one-directional rotation mechanism, utilize described one-directional rotation mechanism human body on pedal up and down the power of shake be transformed into and drive the power that slide plate advances.Because the described latch plate extended length that goes up arch is limit, the slide plate speed of a motor vehicle is very slow, and interest is not high so object for appreciation is got up, and train on is also undesirable.Seek out the essential human body chattering frequency up and down of accelerating of the desirable speed of a motor vehicle, physical demands is big again, is difficult to realize its commercial object.

Summary of the invention:

In view of there is above-mentioned deficiency in prior art, technical problem to be solved in the utility model is to improve the type of drive of self-moving slide board, improves slide plate speed, improves the interest of self-moving slide board.

The technical solution that the utility model addresses the above problem is:

A kind of self-moving slide board comprises the front-wheel that is located under the pedal, the service brake device that has the trailing wheel of mono-directional overrun clutch and be located at trailing wheel top, it is characterized in that described pedal is by the front running board of trampling for the forward foot in a step with step on the tail skid of pedaling for the rear foot and form; Front-wheel is articulated under the front running board, and front running board is articulated in a vehicle frame front end; Vehicle frame has an extension spring, and the end system of this extension spring is connected under the tail skid, and other end system is connected to the front portion of vehicle frame, is provided with a guiding bindiny mechanism between tail skid and vehicle frame; Trailing wheel is articulated in the rear portion of tail skid.

The both sides that a preferable embodiment of guiding described in the utility model bindiny mechanism is a vehicle frame are provided with parallel channled rail, and both sides are arranged with two rollers respectively below the tail skid, and described roller is embedded in the channled rail.

The both sides that another preferable embodiment of guiding described in the utility model bindiny mechanism is a vehicle frame are provided with parallel dihedral guide rail, and both sides are arranged with two roller set respectively below the tail skid, and the roller clip of described roller set is held on the horizontal sides of dihedral guide rail.

Sporter's bipod is stepped on respectively on the front running board and tail skid of self-moving slide board described in the utility model, the rear foot is stepped on backward and is pedaled, because trailing wheel is provided with the effect of single freewheel clutch, trailing wheel does not change, rear riding force must be delivered on the front-wheel by the forward foot in a step, the elastic force pulling vehicle frame that overcomes extension spring travels forward, in case remove the rear riding force on the tail skid, extension spring just spurs tail skid and travels forward.Repeat above-mentioned action repeatedly, self-moving slide board one described in the utility model is stretched one and contracted, and car connects the people and travels forward together, and as roller skating, speed is fast, and is interesting strong.
