Description

China's land curling stone

Technical field:

The utility model relates to sports movement appliance, particularly a kind of on floor, land, place, ornamental stone face, carry out the curling stone of amusement training and competition.

Background technology:

Curling stone, also known as curling, originates from Scotland, and the popular game carrying out a kind of spin similarly on ice in 14th century Scotland, started to occur that curling stone is competed in 16th century.18th century imported North America into.Within 1807, import Canada into, Canada has more than 150 ten thousand people playing curling stone at present, is curling stone shop everywhere, and Canada is curling stone power, and the whole people popularize.Curling nineteen ninety-five imports China into, Physical Culture and Sports Commission of Heilongjiang Province determines this motion of curling stone to introduce China, Canada curling stone association and Japanese curling stone association make a special trip to a certain place to China come, hold a training class, after 8 years, curling becomes Nagano Winter Olympic Games event, 2003, curling stone national team of China founds the team, in the Pacific Ocean curling stone championship of 2005 after 3 years, Chinese women's team defeats the teams such as Japan, Korea S, Australia, New Zealand, has won champion, 2010, women's team of Vancouver Winter Olympic Games China obtained the good result of third.Although " this project has the time of 14 years till now from ' introduction '; achieve surprising achievement and progress in world-class match; current domestic curling stone moving whole development is slower; popularity is lower; the sportsman of curling is engaged in less than 200 people in the whole nation; affect reason that curling develops at home a lot, topmost bottleneck problem is exactly the restriction of place and equipment.Prices are rather stiff for one curling stone, nineteen ninety-five the price of a curling stone will more than 10,000 yuan, they are two years old, curling needs special place, build road, place, special curling stone shop and need a large number of fund, because domestic various places economic situation is different, current this place can not be popularized.For also can curling be carried out on land, the research of existing multiple land curling stone both at home and abroad, the U.S. and Canadian curling stone association start " curling of body-building shop " and plan, have developed land curling stone analogue system, a kind of pallet of light metal framework, satisfied the carrying out of precision bearing on pallet grows distance " slip ", 360 degree of swiveling wheels on pallet can slide along any direction, may be used for curling is carried out on paint ground level and smooth in body-building shop, its curling stone stone simulation weight is 13.62kg.U.S. part school has also carried out the curling of miniaturized land in body-building shop in addition, and its land curling stone and slide plate have employed plastic body structure.The Wang Xin in the Inner Mongol in 2006 has invented a kind of dry ice kettle, its curling stone comprises a kettle body, planar motion mechanism is connected below kettle body, planar motion mechanism comprises the motion connected body connected with kettle body, the bottom bearing rolled with earth surface is installed below connected body, connect above kettle body and advance afterburning body, advance above afterburning body and connect thrust handle.When curling stone travels forward, a turning moment can be produced by thrust handle, movement locus is changed.But the profile of above-described technology, size, weight and motion mode, acrobatics and tumblings and real curling are not close.

Summary of the invention:

Overcome the deficiencies in the prior art, design the Chinese land curling stone of a kind of domestic building stones processing and autonomous Design home part composition.China's land curling stone by primarily of coupling nut, curling stone stone body, curling stone stone body protection plate, swivel bearing group bracket in curling stone lid, curling stone lid, horizontally rotate bearing, horizontal eccentric rotary truss, horizontally rotate bearing, truss internal fixtion movable pulley, center rotating bearing, bearing group bracket base pressure lid, center rotating bearing retainer cover, curling stone lid connecting bolt etc. form.Under curling stone stone body, recess embeds stone body protection plate, and stone body disc is embedded in swivel bearing group bracket, and the external edge of curling stone is inlayed 6 and horizontally rotated bearing, its endoporus embeds horizontal eccentric rotary truss, truss internal fixtion movable pulley, truss on it spindle nose through horizontally rotating bearing, be tightened by nut.Truss internal fixtion 6 movable pulley composition Universal pulley groups.Bearing group carrier center portion embeds center rotating bearing, base plane has bearing group frame gland its capping to be fixed, center rotating bearing inner sleeve is installed with center rotating bearing retainer cover, curling stone lid connecting bolt passes from care set endoporus and curling stone stone body centre bore, and the spiral shell button of upper end screws with the coupling nut in curling stone lid and is connected.Utility model works principle is on indoor or outdoors entirely place, promote curling stone body to slide on ground Ground, make curling stone body produce inertia force and promote the direction linear slide advance of the Universal pulley group on bearing group bracket by power, as needs curling stone body move in curves impact target arc time, rotatable lid handle, curling stone stone body is rotated, and curling stone stone body rotates and is advanced by camber line in advance.China's land curling stone is at the motion mode of curling, under the prerequisite of rule, change " place " conditions environmental on its special ice, be transplanted to land " stone kettle " motion carried out on land corresponding " place ", bottom stone kettle, setting-in horizontally rotates the rolling bearing group with vertical rotation, other profiles, size, weight is the same with curling stone, ice matter is changed over floor or place, ornamental stone face, " sliding friction " in original curling stone and ice face is caused to become the rolling bearing of stone kettle setting-in and the rolling friction in floor or place, ornamental stone face, keep the movement velocity of stone kettle and the movement velocity of curling stone on ice face close, the realization of this technology, utilize Chinese existing Stadium and place existence conditions, domestic building stones resource and production domesticization instrument equipment, reach the interest of curling stone, make society of machine-operated school all can realize land curling under limited conditions.
