Description
Technical field
The present invention relates to a kind of checkout equipment, specifically, what relate to is a kind of length-measuring appliance of toy elastic tether, is used for measuring toy at rotary course, the maximum length of toy elastic tether.
Background technology
Climbing top Yo-Yo (YO-YO ball), one be called as " second largest in the world ancient toy ", normally processed by resilient material, and an end has the fake that can be enclosed within on the finger, and the other end is soft object.Constantly bring forth new ideas and develop through many year, Climbing top Yo-Yo becomes a worldwide acrobatic gymnastics on hand.The light weight of Climbing top Yo-Yo has lovely luster, soft and whippy characteristics, and a kind of educational toy of Chang Zuowei obtains the head of a family's favor, is selected as children's toy and plays.To having the toy of tether,, when child is at play,, will cause very big danger in case let tether twine neck if tether is oversize.The data statistics of the incident of suffocating that is caused by Climbing top Yo-Yo shows, 3 to 6 years old children are that the Climbing top Yo-Yo number of suffocating in the incident is maximum.Therefore; Length qualification detection to the toy elastic tether seems particularly important; Particularly when the toy of Climbing top Yo-Yo as children; Its mechanical-physical safety examination is become the important content of toy safety standard-required, the maximum length that its tether has in the time of must measuring Climbing top Yo-Yo and under certain speed, rotate.
Regulation in U.S.'s toy standard (ASTM F963-2011): the quality of the terminal object of toy elastic tether is greater than 0.02kg, and when rotating with 80r/min speed, its tether length should be less than 50cm.Too the qualification of the toy Climbing top Yo-Yo that supplies playing by children is detected in toy safety standard (EN 71-1:2011) mechanical and physical performance of Europe and done relevant regulations.
At present, the measurement of the domestic maximum length that its tether has when Climbing top Yo-Yo is rotated under certain speed does not still have the very tester or the proving installation of standard.Common way is drawing of toy elastic tether to be enclosed be fixed on the support, utilizes motor that Climbing top Yo-Yo is rotated, and probably measures the maximum length that tether has with ruler again.The data that adopt this method to record are very inaccurate; Because gesticulate measurement at a distance with ruler; Can only judge the Climbing top Yo-Yo length that tether extends fully in rotary course far below or considerably beyond 50cm, and in 40～60cm interval, can not get tether extended length value accurately.The problem of needing solution badly is: on level or the plane near level, the speed that is not higher than 80r/min with constant speed 80r/min or maximal rate is rotated Climbing top Yo-Yo, measures the maximum elongation length of toy elastic tether.
Whether utility application (application number " 201020026446.9 ") though can to detect the toy tether qualified, and easy to use, can't accurately measure the maximum elongation length value of tether, and the improvement of manufacturer is not had very big help.
