Description

TECHNICAL FIELD

[0001] The utility model relates to a table tennis bat for rubbing ball, pull ball training belongs to sports equipment technical field. BACKGROUND

[0002] Table tennis is an official competition item of the Olympic Games, and is widely loved by the public due to its combination of competitiveness and interestingness. In table tennis, the bat is not only the core competitive equipment, but also an important carrier for technical training.

[0003] Scientific experiments show that the ball hitting stability of athletes has significant correlation with the characteristics of the equipment. The ball hitting area of a traditional table tennis bat is relatively large (about 15 cm x 15 cm), which causes the touch points of the trainer to be dispersed when hitting the ball, making it difficult to form stable and accurate ball hitting muscle memory and correct hitting action, thereby causing the problem of low hitting rate and difficulty in improving the speed of the return ball due to uncoordinated force.

[0004] The rubbing ball technique requires the touch point to be located in the middle and lower part of the bat face. Due to the large area of the traditional bat, the trainer is prone to problems of high or lateral touch point, resulting in low power transmission efficiency, insufficient friction, insufficient ball rotation, and unstable arc control, making it difficult to form stable and accurate ball hitting muscle memory and correct hitting action.

[0005] The pull ball technique requires the touch point to be located in the middle and upper part of the bat face. Due to the lack of constraints on the ball hitting area of the traditional bat, the trainer is prone to problems of "rubbing the edge of the bat" or the touch point being too low, resulting in low power transmission efficiency, insufficient friction, and unstable arc control.

[0006] The prior art lacks a special training tool for rubbing ball and pull ball actions. INVENTION CONTENTS

[0007] The utility model aims to provide a table tennis bat for rubbing ball and pull ball training to solve the problems raised in the background art.

[0008] The technical solution of the utility model is as follows:

[0009] A table tennis bat for rubbing ball and pull ball training, comprising a handle with a longitudinal axis at an angle α and a bat plate, characterized in that:

[0010] The bat plate is an elliptical structure with a major axis of 8-10 cm and a minor axis of 4-6 cm;

[0011] The angle α is 14-20°;

[0012] The side of the bat plate close to the longitudinal axis of the handle is detachably provided with a counterweight.

[0013] Preferably, the side wall of the bat is provided with a groove matching the shape of the counterweight, and the counterweight is arranged in the groove.

[0014] Preferably, the counterweight is made of lead.

[0015] Preferably, the mass of the counterweight is 50g-100g.

[0016] Preferably, the handle is made of carbon fiber material.

[0017] Preferably, the bat includes a bottom plate, and front and back rubber sheets arranged on the front and back surfaces of the bottom plate.

[0018] The utility model has the following beneficial effects:

[0019] By reducing the effective hitting area, the player is forced to concentrate on the contact point when hitting the ball, the spatial perception of the player is strengthened, and the problem of "hitting point deviation" is improved, thereby improving the hitting stability of the player.

[0020] The counterweight balances the change in weight distribution caused by the reduction in the size of the bat, thereby maintaining the moment of inertia of the bat after the size is reduced, and avoiding the deformation of the action caused by the reduction in the size of the bat.

[0021] The counterweight can be detachably installed on the side of the bat, and the overall weight can be balanced by adjusting the thickness of the counterweight to facilitate adaptive training. BRIEF DESCRIPTION OF DRAWINGS

[0027] The utility model will be described in detail below in combination with the drawings and specific embodiments.

[0028] A table tennis bat for ball rubbing and pulling training, as shown in Figs. 1-3 It includes a handle 5 and a bat 6; the size of the handle 5 is the same as that of a conventional bat.

[0029] The clapboard 6 comprises a bottom plate 3, the front surface of the bottom plate 3 is provided with a front rubber 2, and the back surface of the bottom plate 3 is provided with a back rubber 4.

[0030] The clapboard 6 is in an elliptical shape, and the longitudinal axis of the clapboard 6 and the longitudinal axis of the handle 5 form an inclined angle a of 14-20 degrees, as shown in the figure, the longitudinal axis direction of the clapboard 6 is the major axis direction, and the direction perpendicular to the longitudinal axis of the clapboard 6 is the minor axis direction; the major axis length L1 of the clapboard 6 is 8-10 cm, and the minor axis length L2 of the clapboard 6 is 4-6 cm.
