Description
Technical field
This utility model relates to take-off board technical field, particularly relates to a kind of physical education take-off board.
Background technology
In physical education, take-off board is one of conventional apparatus, particularly in the sports events such as long-jump and pommel horse.Existing take-off board, makes athlete or student obtain the power-assisted of take-off the resilience force of pedal by spring upper end.This take-off board is fixed due to spring, step on during take-off and athlete can be produced different take-off power-assisteds the different local of pedal, it is totally unfavorable for begining to learn the student of long-jump and pommel horse, it is not easy to them and grasps acrobatics and tumblings quickly, we have proposed a kind of physical education take-off board for this, be used for solving the problems referred to above.
Utility model content
The purpose of this utility model is to solve the shortcoming existed in prior art, and a kind of physical education take-off board proposed.
To achieve these goals, this utility model adopts the technical scheme that
A kind of physical education take-off board, including base and pedal, the side of described base is provided with the 3rd groove, by rotating shaft, pedal is installed in described 3rd groove, the upper end edge horizontal direction of described base is sequentially provided with the first groove and the second groove, described base is provided with expansion link away from the side of the 3rd groove, the upper end of described expansion link is provided with buffer stopper, it is provided with the first spring in described first groove, it is provided with the second spring in described second groove, the lower end of described pedal is provided with buffer stopper by the 3rd spring, the lower end of described buffer stopper is provided with the first contiguous block and the second contiguous block, the upper end of described first spring and the first contiguous block connect, the upper end of described second spring connects the second contiguous block.
Preferably, described expansion link is provided with fixing device, and described fixing device is lock-screw.
Preferably, described 3rd spring is set in qually spaced between pedal and buffer stopper.
Preferably, the Surface coating of described buffer stopper has sponge.
In this utility model, base arranges multiple spring, and cushioned further by the 3rd spring in the lower end of pedal, when athlete or student ride on pedal, the power stepless action that spring is applied by pedal is on base, no matter step on which position at pedal during athlete's take-off, all can to athlete or abecedarian's comparatively all even identical spring power-assisted of generation, this utility model simple in construction, reasonable in design, well serve the effect of jump help, be suitable for promoting.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of physical education take-off board that the utility model proposes；
Fig. 2 is the side view of a kind of physical education take-off board that the utility model proposes.
In figure: 1 base, 2 expansion links, 3 buffer stoppers, 4 second contiguous blocks, 5 pedals, 6 rotating shafts, 7 the 3rd springs, 8 buffer boards, 9 first contiguous blocks, 10 first springs, 11 first grooves, 12 second grooves, 13 second springs.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.
With reference to Fig. 1-2, a kind of physical education take-off board, including base 1 and pedal 5, the side of base 1 is provided with the 3rd groove, by rotating shaft 6, pedal 5 is installed in 3rd groove, pedal 5 can be rotated by rotating shaft 6, the upper end edge horizontal direction of base 1 is sequentially provided with the first groove 11 and the second groove 12, base 1 is provided with expansion link 2 away from the side of the 3rd groove, the upper end of expansion link 2 is provided with buffer stopper 3, buffer stopper 3 plays the effect of limiting buffer, the first spring 10 it is provided with in first groove 11, the second spring 13 it is provided with in second groove 12, the lower end of pedal 5 is provided with buffer stopper 8 by the 3rd spring 7, when athlete or student ride on pedal 5, the power stepless action that spring is applied by pedal 5 is on base 1, the lower end of buffer stopper 8 is provided with the first contiguous block 9 and the second contiguous block 4, upper end and first contiguous block 9 of the first spring 10 connect, the upper end of the second spring 13 connects the second contiguous block 4.
In this utility model, expansion link 2 is provided with fixing device, and fixing device is lock-screw, and expansion link mainly shows that pedal 5 moves up and down distance.3rd spring 7 is set in qually spaced between pedal 5 and buffer stopper 8.The Surface coating of buffer stopper 3 has sponge, plays the effect of buffering further.
In this utility model, base 1 arranges multiple spring, and cushioned further by the 3rd spring 7 in the lower end of pedal, when athlete or student ride on pedal 5, the power stepless action that spring is applied by pedal 5 is on base 1, no matter step on which position at pedal 5 during athlete's take-off, all athlete or abecedarian can be produced comparatively all even identical spring power-assisted.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive according to the technical solution of the utility model and utility model thereof and be equal to replacement or change, all should be encompassed within protection domain of the present utility model.
