Land curling

Technical Field

The utility model relates to a technical field that the motion was equipped especially relates to a land is with curling.

Background

As is known, a curling is a throwing competition item which is carried out on ice by taking a team as a unit, is a winter Olympic game item, is in a round pot shape, and is made of mica-free Scotland natural granite stone chisel and ground, but the curling is not beneficial to the popularization of the whole people of the item due to the reasons of high production cost, complex processing technology, high selling price, high cost for maintaining the ice field and the like; the land curling is a simple version of curling balls of winter Olympic meeting projects, is a competitive sport which consumes less exercise amount and has throwability, team type, strategy and technology and the like, the land curling is a competition only needing to do a match on a flat ground, the trial playing threshold and the popularization difficulty of the sport are greatly reduced, the land curling is low in technical threshold, quick to operate and less in physical consumption, the rules, tactical arrangement, partial technologies and the like are similar to the height of the traditional curling, the land curling is an important auxiliary training means for innovatively filling non-ice periods in summer, the effects in the aspects of action memory, tactical coordination, simulated ice wiping and the like are particularly obvious, the training interest can be enriched, the attention of athletes on a competition field is promoted, meanwhile, the land curling facility equipment is simple to lay and disassemble and can be moved, the problem of insufficient number of professional curling fields can be partially relieved, the main component of the ice way of the land curling is a high molecular polyethylene material, the special lubricant is sprayed on the curling stone to enable the curling stone to slide on the curling stone, and the lubricant is regularly sprayed, and other maintenance is only needed once a year, so that the curling stone training cost can be greatly saved.

Land curling has the following advantages: (1) energy conservation and environmental protection: the land curling is made of high polymer material by injection molding, has the advantages of low temperature resistance, wear resistance, corrosion resistance, no toxicity, no odor, no water absorption, no need of ice making in a track field and no energy consumption. The maintenance cost is low, and the reliability is high; (2) good economical efficiency: the land curling equipment is relatively simple and convenient, has loose requirements on the field of a stadium, and can be laid on the free space of the stadium, the conference room, the classroom corridor of the school and even the flat cement ground outside the stadium. The land curling is used as a substitute for using equipment for transition of 'ice-to-land and ice-to-land' training and competition of teenagers and athletes, so that the bottleneck problems of overhigh field cost and sport participation cost of a curling house are fundamentally solved; (3) competition and entertainment: the land curling can organize competition sports according to the competition rules of winter Olympic game curling, has entertainment and interest, and can be purchased by vast universities and commercial institutions at low cost for developing teaching and body-building sports. The land curling equipment can be used as equipment for specified match of the independent setting item of the 2020 winter transportation meeting held in China; (4) the whole people build body: the land curling is an ice-free curling motion form, is suitable for both men and women, teenagers and the old, is suitable for professional athletes and common people, and can conveniently carry out fitness entertainment and competition activities in living quarters and public squares; (5) all-weather all-region: the curling for land does not need the freezing temperature and field in winter, is suitable for being developed in winter and summer, is suitable for being developed in a venue and in the open air, and is all-weather and all-region healthy and all-people sports; (6) the culture attribute is good: the team cooperation sports project can cultivate participants to form good characters in the activity, shape perfect quality, and cultivate collective cooperation spirit and team honor feeling in competition; (7) is an intelligent game sport and is beneficial to the intelligence development of the participants at low ages. 16 land curling is required to be thrown out completely, the throwing technology included in the throwing technology needs to carry out mental calculation and analysis activities, the calculation capability, the analysis capability, the judgment capability, the observation capability, the attention and the like of the children can be trained and cultured, and the intelligence development of the children is facilitated.

However, the land curling used on the land currently has the following disadvantages:

1. the special equipment has general quality and single structure, and can not meet the requirements of special equipment with various specifications, weights and high-end matches to adapt to different physical performance span ranges from children, students to amateurs and old people to professional athletes;

2. the production process is complex, two injection molds of two layers of shells are needed for carrying out the hard inner shell forming and the soft rubber outer shell coating secondary injection molding process, and more additional manufacturing molds and more occupied injection molding machines are needed for production, so that the defects of low production efficiency and high cost exist;

3. in the use process of the universal ball bearing, foreign matters such as dust and hair are easily brought into the bearing to cause unsmooth rolling and even blocking locking, so that the result of competition results is influenced, and even the competition cannot be normally finished;

4. the existing land curling is only coated by a soft rubber buffer layer covered by a full shell, and the whole land curling is scrapped due to the local damage of a circle frequently collided in competitions, so that the life cycle of the land curling in the training and competition process is short, the consumable material consumption of land curling equipment is high, and the defect is not favorable for the popularization of the land curling motion;

5. the land curling which is available at present requires high investment of manufacturers to manufacture more moulds and more production equipment if the curling is to meet the weight of various specifications.
