Description
Technical field
This practicality is is newly tamed and dociled and is related to a kind of volleyball drop-shot training device, belongs to athletic training equipment.
Background technology
In China, a lot of colleges and universities all can offer vollyball course.P.E. teacher can teach student various volleyball skills on classroom, comprise service, receive, pass, slam-shot etc., wherein, slam-shot is that a lot of students are difficult to a technology of grasping, at present, owing to there is no special spiking training device, teacher needs ceaselessly ball to throw to and help student in the air and complete knock.
Utility model content
The utility model, for the problem in background technology, proposes a kind of volleyball drop-shot training device, to help student's complete independently spiking training, has alleviated teacher's burden.
The utility model, for overcoming the above problems, adopts following technical scheme:
A volleyball drop-shot training device, comprises base, montant, cross bar, motor, reel, spring rope, vollyball, single chip machine controlling circuit and motor-drive circuit; The bottom of described montant is connected with base, its top is connected with one end of cross bar; Described motor is fixed on the other end of cross bar; The rotating shaft of described motor is connected with the central shaft of reel, one end of described spring rope is wrapped on reel, and its other end is connected with vollyball; On described montant, be also provided with a rising button and a decline button; Described single chip machine controlling circuit is controlled machine operation by motor-drive circuit; Described rising button is all connected with the signal input part of single chip machine controlling circuit with decline button.
Preferably, described motor adopts stepper motor.
Technique effect:
1, the utility model can help student's complete independently spiking training, has alleviated teacher's burden.
2, can to the height of vollyball, adjust by button, to meet different training requirements.
3, the utility model is simple in structure, designs ingeniously, is adapted at each school and promotes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit structure block diagram of the present utility model.
Label title in Fig. 1: 1, base; 2, montant; 3, cross bar; 4, motor; 5, reel; 6, spring rope; 7, vollyball; 8, rising button; 9, decline button.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done in further detail and is introduced:
Structure of the present utility model as shown in Figure 1, comprises base 1, montant 2, cross bar 3, motor 4, reel 5, spring rope 6, vollyball 7, single chip machine controlling circuit and motor-drive circuit; The bottom of described montant 2 is connected with base 1, and its top is connected with one end of cross bar 3; Described motor 4 is fixed on the other end of cross bar 3; The rotating shaft of described motor 4 is connected with the central shaft of reel 5; One end of described spring rope 6 is wrapped on reel 5, and its other end is connected with vollyball 7; On described montant 2, be also provided with a rising button 8 and a decline button 9.
As shown in Figure 2, described single-chip microcomputer control control circuit is controlled motor 4 work by motor-drive circuit to circuit structure of the present utility model; Described rising button 8 is all connected with the signal input part of single chip machine controlling circuit with decline button 9.When user presses decline button 9, single chip machine controlling circuit can be controlled motor 4 and rotate, and the spring rope 6 on reel 5 is slowly emitted, thereby the height of vollyball 7 is declined; When user presses rising button 8, single chip machine controlling circuit can be controlled motor 4 counter-rotation, the spring rope 6 on reel 5 is slowly regained, thereby made the height of vollyball 7 increase.
Described motor 4 adopts stepper motor; The L298N doube bridge driver of the main YouST of described motor-drive circuit company forms; Described single chip machine controlling circuit mainly consists of the C8051F020 microprocessor of Silicon Labs company, and this microprocessor is fully-integrated mixed-signal system level MCU.
During use, teacher can adjust to suitable training height by vollyball 7 by rising button 8 and decline button 9, and after student's slam-shot, the vollyball 7 flying out can be got back to original position under the pulling force effect of spring rope 6, and now, student can proceed knock next time.
