Description
Technical field
The utility model relates to sports equipment technical field, is specifically related to a kind of tennis training release device.
Background technology
Tennis development is swift and violent, is deeply subject to extensively undergraduately to like, the Physical Education Departments of a lot of colleges and universities has been offered tennis specialty, and also becomes one of Public Physical Education elective course.Tennis Major and Physical Education Course student are when training, generally need at least one training mate, often owing to lacking ladder player, or the technology such as rotation of service dynamics, angle, far and near distance and the ball of training mate are not stable in performance, and cause training effect not good enough.
In order to solve this two hang-up, designed a kind of not only economy but also practical service robot, allow more student can more comfortable, more effectively carry out multi-ball practice.Simple and easy tennis serve machine for correcting student's malfunction, shorten study action extensive and time differential period, reach automation fast and there is good practice effect, for improving tennis teaching quality, there is very large facilitation.
Utility model content
The purpose of this utility model is to provide a kind of tennis training release device.
In order to realize above object, the utility model adopts following technical scheme:
A tennis training release device, comprises storage ball frame, and storage ball frame lower end is provided with lower ball groove, and the lower end of storage ball frame and lower ball groove junction is provided with a support, and support lower end is provided with a base; Described lower ball groove middle section position is provided with a top board and a kick back; Described support upper end is provided with trigger, and described trigger left side is provided with triggers connecting rod one, and described triggering connecting rod one is connected with the top board in lower ball groove stage casing.
The ball mouth place of described lower ball groove is provided with one and goes out ball stopper plate, described in to go out ball stopper plate be detachable sideboard.
Described trigger upper end is provided with triggers connecting rod two, and described triggering connecting rod two extends to the lower ball hole of storage ball frame bottom.
Top board in described lower ball groove is inclined-plane top board.
The described lower ball angle of the v-groove can regulate.
Described support height can regulate.
Described storage ball frame is infundibulate.
Described trigger is clocked flip-flop, and the described trigger time interval is set to 2～20 seconds.
Tennis training provided by the invention release device, puts into storage ball frame by tennis, and the tennis of placing can lean on Action of Gravity Field to transmit successively downwards.When tennis enters lower ball groove, because lower ball groove is inclined design, tennis can roll downwards successively, and tennis to lower ball groove stage casing will be stopped by ball-blocking plate, and be arranged in order.
The tennis bottom being stopped by ball-blocking plate, top board is just in its back lower place, and top board is fixed on and triggers on connecting rod, triggers connecting rod and is fixedly connected on the trigger of support upper end.Trigger can arrange the time interval of triggering, is generally 2～20 seconds, and relies on battery functi on, by triggering small end top board, lower ball groove tennis is bottom pushed and crosses lower ball groove stage casing ball-blocking plate, and this tennis will be rolled into ball mouth along lower ball groove.After this tennis, next tennis still can be stopped by the ball-blocking plate in lower ball groove stage casing.
When tennis along lower ball groove from outlet is rolled out, can with inertia slightly some preshoot land, drop point is fixed, and bounces moderate, can pass through adjusting pole height, controls the jumping height of ball.Meanwhile, going out ball stopper plate and can controlling and slow down tennis in speed and the forward momentum in when outlet of exit, is applicable to the beginner that tennis level is lower.
Release device provided by the invention is simple and easy, portable, economic, practical, for correcting student's malfunction, shorten study action extensive and time differential period, reach automation fast and there is good practice effect, for what improve tennis teaching quality and tennis, universally there is greatest facilitation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment
A tennis training release device, comprises storage ball frame 7, and storage ball frame 7 lower ends are provided with lower ball groove 2, and storage ball frame 7 is provided with a support 9 with the lower end of lower ball groove 2 junctions, and support 9 lower ends are provided with a base 10; Described lower ball groove 2 middle section positions are provided with a top board 3 and a kick back 4; Described support 9 upper ends are provided with trigger 6, and described trigger 6 left sides are provided with triggers connecting rod 1, and described triggering connecting rod 1 is connected with the top board 3 in lower ball groove 2 stage casings.
The ball mouth place of described lower ball groove 2 is provided with one and goes out ball stopper plate 1, described in go out ball stopper plate 1 for detachable sideboard.
Described trigger 6 upper ends are provided with triggers connecting rod 28, and described triggering connecting rod 28 extends to the lower ball hole of storage ball frame 7 bottoms.
The angle of described lower ball groove 2 can regulate.
Described support 9 height can regulate.
Described storage ball frame 7 is infundibulate.
Described trigger 6 is clocked flip-flop, and the time interval of described trigger 6 is set to 2～20 seconds, and the preferred time interval is 10 seconds.
In tennis training, tennis is put into storage ball frame 7, the tennis of placing can lean on Action of Gravity Field to transmit successively downwards.When tennis enters lower ball groove 2, because lower ball groove 2 is inclined design, tennis can roll downwards successively, and tennis to lower ball groove 2 stage casings will be stopped by ball-blocking plate 4, and be arranged in order.The tennis bottom being stopped by ball-blocking plate 4, top board 3 is just in its back lower place, and top board 3 is fixed on and triggers on connecting rod 1, triggers connecting rod 1 and is fixedly connected on the trigger 6 of support 9 upper ends.The time interval that trigger 6 arranges triggering is 2～20 seconds, and relies on battery functi on, by triggering connecting rod one 5 upper end top boards 3, lower ball groove 2 tennis is bottom pushed and crosses lower ball groove 2 stage casing ball-blocking plates 4, and this tennis will be rolled into ball mouth along lower ball groove 2.After this tennis, next tennis still can be stopped by the ball-blocking plate 4 in lower ball groove 2 stage casings.Triggering connecting rod two is that can not fall, by triggering connecting rod two, the regularly up effect of thrust, can make the ball being stuck fall in order in order to prevent that two balls from tumbling to storage ball frame lower end, to be stuck simultaneously.
