Abstract
The utility model relates to a roller skating sled which comprises a sled body, supporting legs and sliding blades. The utility model is characterized in that the sliding blade is provided with a moving wheel and a direction wheel, and the central line of a wheel shaft of the direction wheel is vertical to the bottom sliding blade and can tilt left and right along the vertical line within a range from 0 to 15 DEG. The utility model can slide on a circular arc slide way on dry land so that the sledding sport can be carried on and popularized in any regions and seasons. The utility model has the advantages of novel structure, agile steering and strong interest.
Description
The utility model relates to a kind of sledge, particularly a kind of Roller skating sled of sliding in the circular arc slideway of nonirrigated farmland of being suitable for.
Sledge is a kind of sports of carrying out in ice and snow circular arc slideway, is one of Winter Olympic Games ice and snow sporting events, owing to this motion is not only taken exercises but also temper one's willpower, so also be a kind of body building that numerous sports enthusiasts like.But often because of the influence in region or season, make this body building of sledge can not be in office where the territory, extensively carry out any season and popularize.
The purpose of this utility model be to provide a kind of novel structure, interesting strong, be easy to popularize the Roller skating sled that can in the circular arc slideway of nonirrigated farmland, slide.
The purpose of this utility model is achieved in that
A kind of Roller skating sled comprises prying body, supporting leg, sliding cutter, it is characterized in that sliding cutter 3 is provided with moving wheel 4 and steering wheel 5; The sliding cutter 3 in wheel shaft 8 center lines of its steering wheel 5 and bottom is vertical, and can be along the vertical line 0-15 ° of scope that be tilted to the right left.
The runner 7 of moving wheel 4 or steering wheel 5 is by two semicircle spheroid engagements, and connects firmly on support 9 by wheel shaft 8, and two axial ends is provided with friction zone circle (10) in the middle part of being provided with ball (12), adjustment nut (13), runner (7) in the runner 7.
The utility model will have now on the sliding cutter in sledge bottom and install runner additional, can slide in the circular arc slideway of nonirrigated farmland, make sledge sport where territory in office and can both be carried out and popularize season.The utility model novel structure, turn to flexibly, interesting strong.
Description of drawings:
Fig. 1 is the front view of the utility model structural representation.
Fig. 2 is the rearview of the utility model moving wheel in slideway.
Fig. 3 is an I portion enlarged drawing among Fig. 2.
Fig. 4 is an A-A zoomed-in view among Fig. 3.
Fig. 5 is the utility model steering wheel motion schematic diagram in slideway.
The utility model is described in further detail below in conjunction with drawings and Examples: consult shown in Figure 1, prying body 1 bottom of Roller skating sled is equipped with two sliding cuttves 3 by supporting leg 2, is separately installed with the moving wheel 4 of symmetric position and same number on two sliding cutter 3 horizontal planes; On two sliding cutter 3 anterior arc surfaces, be separately installed with the steering wheel 5 of symmetric position and same number.
Consult Fig. 2, Fig. 3, shown in Figure 4, each is parallel with the tangent line at the cambered surface point of contact (being stress point) of circular arc slideway 6 to wheel shaft 8 center lines of moving wheel 4, makes moving wheel 4 directions of motion parallel consistent with sliding cutter 3.Be provided with an annular boss in the middle of the wheel shaft 8, each suit one needle bearing 11 on the boss both sides wheel shaft 8, runner 7 is made up of the two halves spherosome, be set in outside the needle bearing 11, can do needle bearing 11 outer applying mechanically simultaneously, the two halves spherosome concavo-convex 14 meshes into a spherosome on contact-making surface, the friction zone circle 10 of profile of tooth is installed on both sides, spherosome middle part to be had in the cast groove of corresponding profile of tooth, a little more than spherome surface, friction zone circle 10 adopts rubber, plastic or other material to make, have elasticity, can increase the frictional force of runner 7.Adjust nut 13 and lay respectively at runner 7 two ends, spinning is on wheel shaft 8, and runner 7 two ends are equipped with a circle semicircle groove, adjust nut 13 with it in opposite directions connecting end also be provided with the onesize semicircle groove of a circle, therebetween is equipped with a circle ball 12; When runner 7 rotated, runner 7 drove ball 12 and rotates, and reduces friction.Adjust nut 13 and be used for the adjusting play and the fixing two halves spherosome of runner 7, runner 7 is rotated flexibly; Wheel shaft 8 two ends are packed on the support 9, and sliding cutter 3 connects firmly with support 9 welding.
Consult shown in Figure 5ly, all steering wheels 5 all are equidistant being installed on two sliding cutter 3 anterior arc surfaces, and all the angle of inclination of steering wheels is identical, and its wheel shaft 8 center lines are vertical with the sliding cutter 3 in bottom, are tilted to the left 5 ° and slide cutter 3 and connect firmly along vertical line; When Roller skating sled drove to slideway 6 turnings, steering wheel 5 turned to along slideway 6 orbiting motions.
