Description
Technical field
The utility model relates to physical culture appurtenance, particularly relates to a kind of sit-ups subtest device.
Background technology
At present, relevant department has specified that school must comprise the physical examinations of eight projects of " sit-ups " to student.The quality of physique constitution of students all has a certain impact to enter a higher school, job hunting etc., for this reason, the detection method of science must be adopted to carry out physical examinations to student, to draw correct test result.In sit-ups test in the past, coordinate the method for stopwatch often by people's manual count, although this kind of method is simple, owing to there is manual operation therefore cannot avoiding makeing mistakes, and in test process, needs manpower to get involved, waste manpower and materials.Along with the development of science and technology, started have some electronic type type register for sit-ups to release in recent years, they can complete the self-timing counting of sit-ups, but this kind of apparatus structure is comparatively complicated, usually need to be designed to bed structure, and connection cable is more, result in that small product size is comparatively large, inconvenience is mobile, connect complicated and use the drawbacks such as loaded down with trivial details.
Utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of structure simple, easy to use, and has the sit-ups subtest device of automatic counting function.
A kind of sit-ups subtest device described in the utility model, comprise base, foot's fixture, support bar and electronic display unit, described base is the main element of a kind of sit-ups subtest device described in the utility model, described base is provided with foot's fixture, described foot fixture is connected by connecting rod with described base, described connecting rod is bar king-rod structure, according to foot's size adjustment height of different student, described connecting rod is provided with adjusting nut A, on described base, the rear of described foot fixture is provided with support bar, the top of this support bar is provided with electronic display unit, described electronic display unit is provided with electronic inductor, display screen, timer and battery, described electronic inductor, display screen, timer is connected at described electronic display unit internal circuit with battery, described support bar is bar king-rod structure, be provided with adjusting nut B above, electronic display unit is regulated suitable height by the height according to different student.
A kind of sit-ups subtest device described in the utility model, simple and reasonable, be placed on the tail end of foam-rubber cushion during use, electronic display unit can sense counter automatically, and do not need extra artificial counting, student oneself can complete test separately, simple to operate, easy to use, easy to utilize.
