A kind of long-jump device of automatic range flat sand
Technical field
The present invention relates to teaching technique field, specially a kind of long-jump device of automatic range flat sand.
Background technology
On physical education, long-jump is a basic technical ability, student needs exercise and takes an examination, at present, classmate is after long-jump finishes, measure the distance of long-jump by tape measure, so lead to long-jump to be to also need to the cooperation of many people it is impossible to carry out single training, and the range deviation measuring is too big, it is unable to reach real justice, and need special personnel to even sand out after finishing, so that next classmate's long-jump calculates long-jump distance, the efficiency of artificial flat sand is low, and flatness is not high, easily have influence on the achievement of next bit classmate.
Content of the invention
It is an object of the invention to provide a kind of long-jump device of automatic range flat sand, to solve the problems, such as to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:A kind of long-jump device of automatic range flat sand, including sand pit and sand, described sand pit be internally provided with pressure apparatus, described pressure apparatus be internally provided with pressure transducer, described sand pit side is provided with display lamp, and this display lamp is corresponding with pressure transducer, the side of described pressure apparatus is take-off portion, the both sides in described sand pit are provided with track frame, the inside of described track frame opens up fluted, described groove be internally provided with pulley, and the inside of groove is additionally provided with the track corresponding with pulley, the side of described track frame is provided with door type frame, and door type frame is connected with flat sand rod by connecting rod, described pulley passes through drive link and the outfan of motor connects, described motor is located at the outside of door type frame, the side of described door type frame is provided with control panel, this control panel electrical connection pressure apparatus and motor.
Preferably, described motor is located at the inside of motor housing, and motor housing is located at the outside of door type frame.
Preferably, the surface in described take-off portion is provided with raised line.
Preferably, the side in described take-off portion is provided with infrared ray sensor and the warning light being connected with infrared ray sensor, and this infrared ray sensor and warning light all electrically connect control panel.
Preferably, described pressure transducer is horizontal stripe shape, and is evenly arranged between sand and ground.
Preferably, the side of described display lamp is provided with corresponding long-jump range index
Compared with prior art, the invention has the beneficial effects as follows:The long-jump device of this automatic range flat sand passes through to arrange pressure apparatus, when student jumps to sand pit, huge pressure is applied to pressure transducer, signal is passed to display lamp by pressure transducer, display lamp lights, can automatically show that student has jumped distance how far, easy to use, and measure precisely, by arranging automatic flat sand device, the automatic flat sand after long-jump, conveniently save trouble, and save the time, the long-jump device of this automatic range flat sand conveniently saves trouble measurement precisely, is effectively guaranteed the long jump result of student.
