Description

Ball dry snow module

Technical Field

The utility model belongs to dry snow skiing equipment industry, concretely relates to ball dry snow module.

Background

The dry snow product is used as a substitute of real snow, has no requirement on the climate of the application environment, is the greatest advantage of dry snow, can be opened in areas without snowfall, and can be continuously operated in four seasons. In order to make the sensation of skiing on dry snow as close as possible to that of skiing on real snow, dry snow products must solve two key problems: first, the coefficient of friction of drought snow and snowboard, second, the snowboard ability of grabbing on drought snow, at present, the industry does not have these two problems of solution that a drought snow product can be fine yet.

The starting slope of the snowboard on the real snow is 4 degrees, the starting slope of most dry snow products is 9 degrees at present, the friction coefficient of the dry snow and the snowboard determines the starting slope of the dry snow, the starting slope determines the slope requirement of a snow road, the larger the starting slope is, the poorer the adaptability of the dry snow products to the terrain is, the snow-catching capacity of the snowboard on the dry snow determines the lateral slipping degree of the snowboard when the snowboard stands on the edge, the stronger the snow-catching capacity is, the smaller the slipping degree is, and the snow-catching capacity of the snowboard on the dry snow is a key factor for the high-grade skiing technology to play on the dry snow.

There are four major categories of dry snow products in the dry snow industry at present: brushes, combs, needle mushrooms and woven blankets, the brushes, the combs and the needle mushrooms have relatively high friction coefficient, the sliding gradient is 9 degrees, and a water spraying system is required to be matched for increasing lubrication when the brush, the combs and the needle mushrooms are used. Due to the limitation of 9 degrees of the starting slope, the requirement of the dry snow on the slope of the snow track is high, the gentle hillside is not suitable for installing the dry snow, and the brush type and comb type dry snow products are not suitable for the high-grade track.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a ball roller snow-dry module, the principle of the roller snow-dry product of the utility model is that one to a plurality of ball strings are connected together, one end is fixed on a base, a plurality of ball strings are fixed on a base to form a module, and the modules are assembled together to form the surface of a skiing way; the bead strings can also be fixed on a blanket, the blanket is spliced and paved together to form a ski run, the friction between all dry snow products and the snow board in the industry at present is sliding friction, and due to the limitation of materials, the friction coefficient which is as small as that between real snow and the snow board is difficult to achieve. The ball roller dry snow has the characteristics that rolling friction is generated between the snow plate and the dry snow, so that the friction coefficient is reduced. The bead surfaces in the bead string are cambered so that when the snowboard is edged, the contact angle of the curved cambered surface and the bottom edge of the snowboard is perpendicular, thus providing sufficient lateral force, which is the source of snow-catching force.

In order to achieve the above object, the utility model provides a following technical scheme: ball drought snow module, including the base, the top of base is provided with the cluster core, the cluster core is worn to cluster one or more ball and is formed the pearl cluster, and is a plurality of the pearl cluster is installed on the surface of base.

Preferably, the balls can rotate around the axle center on the string core, and the shape of the balls can be various shapes with curved surfaces and irregular shapes.

Preferably, the bead string fixing mode comprises one-end fixing and multi-end fixing.

Preferably, the bead string shape comprises a strip shape, a ring shape, a star shape or a polygon shape, wherein the strip-shaped string is a straight line shape or a curved line shape.

Preferably, the base is made of a material, shape and form without limitation, and may be made of a material having a relatively hard or relatively soft texture, wherein the material having a relatively soft texture includes a non-woven texture and a woven texture, and the woven texture includes a texture of beads directly woven onto the base.

Preferably, the balls on the top of the ball string can roll longitudinally, roll transversely and are fixed and non-rolling.

Compared with the prior art, the beneficial effects of the utility model are that: through the utility model discloses a design lets partly take place rolling friction between snowboard and the drought snow module to reduce coefficient of friction, the ball surface in the cluster core is the curved surface structure, and when the snowboard found the sword, the contact angle of crooked sphere and snowboard bottom sword limit was the vertically, consequently can provide sufficient side direction effort, makes to grab snow stronger, consequently can adapt to the topography of different slopes, great reduction the limitation of current drought snow module.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

A product module consists of three parts: the ball, the string core 3 and the base 1;

the ball is stringed by the string core 3, one end of the string core 3 is inserted into the mounting hole of the base 1 and is self-locked, a plurality of strings of the ball 2 are fixed on the base 1 in a certain arrangement form to form a dry snow module, and the modules are spliced and laid on a slope to form a ski slope;

for a string of single-ball dry snow products, a plurality of strings of cores and balls support the weight of a skier, the elastic strings of cores simulate the software snow environment, the balls at the top are made of self-lubricating materials, and the low friction coefficient of the materials is added with rolling, so that the friction force between the skis and the dry snow is effectively reduced.
