Description

Roller sliding pile

Technical Field

The utility model belongs to the technical field of sports goods, specific theory relates to a smooth stake of wheel.

Background

The skidding pile is also called a flat flower pile and an angle mark, the whole body is of a round table type shell structure, the size is about 70mm (lower bottom surface) in diameter, the height is 80mm, and the specific diameter and the specific height can be adjusted according to actual requirements. The roller can be divided into round heads and flat heads according to external shapes, and the flat head piles are adopted in the formal flat land fancy roller skating match at present. The side surface of the pile body is mainly of a smooth structure, and the part of the side surface is decorated with patterns.

At present, the adopted materials of the roller piles are generally three types of hard plastics, soft plastics and rubber. Hard plastic stakes are cheaper and have the disadvantage of being brittle; the soft plastic pile has the biggest advantages of difficult damage and light weight, but the soft plastic pile generally has thicker wall thickness and higher price because the self-supporting property needs to be maintained; rubber piles are not easily damaged, but are expensive, and are easily twisted with wheels or a tool rest to fall due to a large friction coefficient, so that roller piles made of rubber materials are rarely used at present.

In any material or structure, because the overall appearance of the roller-skating pile needs to maintain the structural stability (the axial stability of the circular truncated cone), when a sportsman falls down on the pile body, certain damage is inevitably caused, and the pile body is damaged; when the wind-driven training aid is used outdoors, the wind-driven training aid is easily blown to the outside under the influence of wind force, and training is influenced.

Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the invention.

The utility model discloses a smooth pole of wheel, as shown in fig. 1, including pile body 1 that has fretwork ventilation structure, pile body 1 is big end down and compressible toper helical structure, and pile body 1's top is equipped with pile bolck 2, and pile body 1's bottom is equipped with base 3, and pile body 1 and pile bolck 2 and base 3 integrated into one piece, the whole profile of smooth pole of wheel are the round platform column structure of a fretwork. The beneficial effects of the utility model reside in that: the roller sliding pile is provided with a pile body 1 with a hollow ventilation structure, the pile body 1 is a tapered spiral structure which is large in size and compressible, the pile body 1 can be compressed after a sportsman falls on the pile body, the pile body 1 recovers the original state after the sportsman leaves, the body of the sportsman cannot be injured, the pile body 1 cannot be damaged, and the pile body 1 is provided with the hollow ventilation structure, so that the influence of wind power cannot be avoided, and the pile body cannot be blown down by wind.

As a preferred embodiment of the present invention, as shown in fig. 1 and fig. 2, the base 3 is a ring structure, the inner side of the base 3 is provided with a cross brace 31, a magnet 32 is arranged in the middle of the cross brace 31, the center of the pile top 2 is provided with an iron sheet 21, and the magnet 32 is located under the iron sheet 21. The pile top 2 is a plane internal spiral structure, and the magnet 32 is positioned at the end part of the internal spiral structure. The base 3 is a plane external spiral structure, and the cross brace 31 passes through the center of the base 3 and is fixedly connected with the base 3 at two ends. The pile body 1 keeps a certain self weight and is more stable when placed by arranging the pile top 2 with the in-plane spiral structure and the base 3 with the out-plane spiral structure; by arranging the cross brace 31, the strength of the base 3 is improved, so that the structure of the base 3 is more stable; through set up magnet 32 in the middle of stull 31, set up the paster at pile bolck 2 centers, the pile body 1 of being convenient for accomodate, when the smooth stake finishes using, compress smooth stake, make magnet 32 hold iron sheet 21, whole smooth stake is a pie structure, and it is more convenient to carry and transport.

As a preferred embodiment of the present invention, the pile body 1 is a tapered spiral structure formed by sequentially winding one or more spiral lines. The section of the spiral line is circular, oval, triangular or polygonal. The utility model discloses the selection range to the material is bigger than traditional structure, and the helix can adopt the material to be rubber, plastics or metal, because this structure is hollow out construction, can save material 1/3 ~ 1/2 for traditional smooth stake. Preferably, as shown in fig. 4, the utility model discloses a helix winding forms, and the top layer of helix is rubber layer 11, and the inside fossil fragments 12 that are the metal material in rubber layer 11. When the pile body 1 with the spiral structure is subjected to an axial impact force, the pile body can elastically deform like a spring, the modulus of the deformation is far lower than the axial modulus of the traditional structure, and the numerical simulation shows that: the axial modulus of the helical structure skidding pile is only 1/3000-1/100 of the traditional skidding pile with the same material volume, namely the counterforce is only 1/(1 multiplied by 100-3000) of that of the traditional structure when the skidding pile is impacted, so that the impact injury of the skidding pile to the skidding pile in the falling process of athletes can be effectively reduced; the conventional skidding pile can be permanently damaged or even lose the use function when deformed under the action of great axial pressure, and the structure can be elastically deformed like a spring when subjected to axial impact force, so that the deformation of the skidding pile can be restored to the state before the stress after the external force is removed, and the purpose of more durability in use is achieved; the spiral lines have enough gaps to be easy to ventilate, so that a better windproof effect is obtained, the spiral structure has 360-degree equivalent ventilation due to the particularity, the wind direction and the wind direction change do not need to be considered in the placing process, and finally, the windproof structure has a larger windproof advantage compared with the traditional hollow windproof structure; by adopting the spiral line with the metal keel 12 structure arranged in the rubber layer 11, compared with the spiral line made of pure rubber or plastic materials, the pile body 1 has good elastic modulus, and has structural stability in the axial direction; compared with a spiral line made of pure metal materials, the spiral line is safer, is not easy to hurt people, and has waterproof and antirust functions.

The utility model provides a smooth pole of wheel, the size is according to the size processing of ordinary smooth pole of wheel among the prior art, and 1 height of its pile body is 80mm, and 3 internal diameters of base are 50 ~ 80mm, and external diameter 50 ~ 100mm, 2 external diameters on pile bolck are 20 ~ 30 mm. Of course, different sizes of skidding piles can be machined as required.

Further, in order to facilitate the identification of the roller pile by the athlete in the movement, the color of the pile body 1 may be various colors, the color of the pile body 1 includes yellow, green or red, and may be one color or a plurality of colors, and the mode of realizing the color of the pile body 1 may be spraying paint, or may be directly processed into the pile body 1 with colors by using rubber raw materials with different colors.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
