Description
Technical field
The utility model is related to a kind of take-off board, more particularly to a kind of physical education take-off board.
Background technology
Currently, in physical education, take-off board is one of common instrument, especially in the sports events such as long-jump and pommel horse
In.Existing take-off board makes sportsman or student obtain the power-assisted of take-off the screen resilience of pedal by spring upper end.It is this
For take-off board since spring is fixed, when take-off, which steps on the different places in pedal, can generate sportsman different take-off power-assisteds, for
It is totally unfavorable to begin to learn the student of long-jump and pommel horse, is not easy to them and quickly grasps acrobatics and tumblings.Therefore, it is proposed that one
Kind physical education take-off board.
Utility model content
The main purpose of the utility model is to provide a kind of physical education take-off boards, can effectively solve background technology
The problems in.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of physical education take-off board, including frame, the frame bottom end are installed with pedestal, the chassis left side
It is embedded with loose slot, movable fixed frame is installed in the loose slot, the susceptor surface is equipped with transverse slat, the transverse slat
Linking has rubber pad on the right side of the top of surface, and spring rod is installed on the right side of the pedestal top, and the transverse slat bottom end right side is solid
Dingan County is equipped with fixed block, and the fixed block bottom end is installed with movable rod, and the movable rod top is installed with convex body, institute
It states movable rod bottom end and is installed with concave volume, the activity fixed frame surrounding is equipped with fixing groove.
Further, the spring rod is embedded with the first spring.
Further, top is installed with fixed link on the right side of the pedestal.
Further, the concave volume is embedded with second spring.
Further, the chassis left side surface is embedded with shaft.
Compared with prior art, the utility model has the advantages that：
1. the physical education take-off board of the utility model, by student in take-off learning process, first in spring rod
Second spring pops up simultaneously in spring and concave volume, is conducive to student during take-off, the higher of jump is farther.
2. the physical education take-off board of the utility model, since during learning take-off board, student steps down in student
On rubber pad on transverse slat, rubber pad has the characteristics that anti-skidding, is conducive to prevent student in the process take-off board of take-off by student
It slides into, accident occurs.
3. the physical education take-off board of the utility model is lived by shaft in loose slot activity by movable fixed frame
Dynamic fixed frame surrounding is equipped with fixing groove, can movable fixed frame be fixed on ground, can effectively prevented in learning process,
Take-off board is subjected to displacement, and take-off is caused to be slipped up.
