Description
Technical field
The utility model belongs to the sports field, particularly a kind of table tennis bat type demonstrator that uses when being used for the table tennis theory teaching.
Background technology
In the table tennis technology theory teaching, need the face shape of explanation racket square stance and touch the position, bulb.At present the main method that adopts is a diagram or the teacher holds the puck and bat is demonstrated.That two kinds of methods all are difficult for accomplishing is clear, demonstrate the angle that racket should have exactly and touch the position, bulb, influence the correct understanding of the batsmanship main points that should have when the learner produces different rotary to table tennis, thereby can't reach the purpose of quick grasp table tennis technology theory.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model proposes a kind of table tennis bat type demonstrator, this demonstrator is provided with the semicircle scale, the nylon table tennis, racket with holes can be demonstrated square stance face shape accurately and touch the position, bulb.It has practical significance to improving table tennis technology theory teaching effect.
The technical scheme that the utility model adopted is: a kind of table tennis bat type demonstrator, this demonstrator main frame is by base and the welding of end square tube, square tube two ends, the end and the welding of semicircle scale bottom, end square tube middle part welding collet, collet oblately is connected by screw axis with holes, oblate top with holes and the welding of square tube bottom, square tube top and the welding of vernier bottom, vernier is enclosed within on the semicircle scale, welding base bottom, vernier top, base top and axle sleeve bottom are by being threaded, and the bolt string is crossed the bearing inner ring hole, and bearing is installed in the axle sleeve two ends, outer race and axle sleeve endoporus interference fit, the fastening bearing inner ring end face of nut, the B locator is equipped with in the axle sleeve outside, bolt top and racket with holes welding.
Described semicircle scale is provided with five angle marks, establishes the A locator on the vernier.
Described racket with holes is provided with five jacks, and the nylon table tennis is provided with latch, and latch can be inserted on the jack of racket with holes.
Described A, B locator comprise round cover, gland, spring and alignment pin.
This demonstrator structure is simple, can be by adjusting its vernier, easily the nylon table tennis is adjusted to various required different angles, the teacher can utilize its racket with holes clear, demonstrate and explain racket square stance on various corresponding different angles exactly, how to make ball moment produce different rotations; And the nylon table tennis can be inserted on the racket jack with holes, the teacher is demonstrated more easily and explain racket batting ball when different parts move issuable camber line and direction of rotation.Therefore, this demonstrator can be assisted the table tennis theory teaching better, be beneficial to teacher's explanation, make the learner more directly observe the angle and the position of racket square stance, understand technology such as easy camber line that produces of different angles and position batting and rotation exactly, thereby grasp the table tennis technology knowwhy quickly.This demonstrator can improve learner's learning interest, satisfies the needs of popular and professional athlete, has important and practical meanings to improving table tennis theory teaching effect.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done explanation in further detail.
Fig. 1 is the structural representation of table tennis bat type demonstrator;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
