Description

Technical Field

[0001] The utility model relates to a sliding type tennis and table tennis strong top spin training device, belonging to the technical field of sports training equipment. Background Art

[0002] Tennis and table tennis are very popular sports. Now most professional tennis and table tennis players, including amateur masters, use topspin to hit the ball with their forehand and backhand. By using topspin and force to hit the ball, the linear speed and angular speed of the ball are enhanced, making the shot fast, deep and stable.

[0003] The most basic technique for topspin tennis and looping table tennis balls is to learn to exert force in the direction of the arc on the circumference, but the point of force should be adjusted according to the rotation of the incoming ball. If the incoming ball is a topspin ball, the hitting position is roughly from the 10 o'clock position to the 11 o'clock position on the clock hand. If it is a backspin ball, the hitting position is roughly from the 8 o'clock position to the 9 o'clock position on the clock hand. When practicing, you need to fine-tune your hitting point according to the actual situation, but there is no corresponding training equipment in the existing training equipment. Students can only rely on themselves to explore the angle and practice, which leads to slow progress in students' ball skills. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a sliding type tennis and table tennis powerful topspin training device, which adopts a sliding rod structure to connect a turntable with a clock scale, so that students can have a more intuitive impression of angles during initial practice, hit the ball in a circular direction, and how to exert force to make the ball obtain a larger angular momentum, thereby enabling students to master the tennis and table tennis serving techniques better and faster.

[0005] In order to solve the above problems, the specific technical solution of the utility model is as follows: a sliding tennis and table tennis powerful topspin trainer, a supporting device is provided on the base, two parallel sliding rails are provided on the top of the supporting device, the sliding ends of the two sliding rails are connected to the center of the striking wheel through bearings, and clock numbers are provided on the surface of the striking wheel.

[0006] The supporting device is an overall K-shaped structure, the bottom of the main support rod is connected to the base through a rotating shaft, one end of the two oblique support rods is connected to the middle of the main support rod through a rotating shaft, and the other ends are connected to the base and the slide rail through the rotating shafts.

[0007] The upper end and the middle of the main support rod are respectively provided with a plurality of vertically arranged positioning holes, the rotating shafts of the two oblique support rods are inserted into any positioning hole in the middle; the rotating shaft connecting the slide rail and the top of the main support rod is arranged in any positioning hole at the upper end.

[0008] A plurality of positioning holes are arranged on the upper oblique support rod, and the middle part of the slide rail is connected with the positioning holes of the upper oblique support rod through a rotating shaft.

[0009] The outer circumferential surface of the striking wheel is provided with a rubber coating.

[0010] The lower surface of the base is provided with a shock-absorbing and anti-skid pad.

[0011] The sliding tennis and table tennis strong topspin training device of the present application adopts the above structure, which enables students to observe the hitting angle more intuitively and solidify the hitting action during tennis or table tennis training, thereby improving the training effect. In addition, the hitting force can be judged by the extension and contraction range of the sliding rod, so that the coach can judge the student's action more intuitively and provide more standardized action guidance. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is the front view of the sliding tennis and table tennis powerful topspin trainer.

[0013] Figure 2 The present invention is a three-dimensional picture of a sliding tennis and table tennis powerful topspin trainer. DETAILED DESCRIPTION

[0014] like Figure 1 and Figure 2 As shown, a sliding tennis and table tennis strong topspin trainer is provided, a supporting device is provided on a base 1, two parallel slide rails 2 are provided on the top of the supporting device, the sliding ends of the two slide rails 2 are connected to the center of a striking wheel 3 through a bearing, and clock numbers 4 are provided on the surface of the striking wheel 3, and the clock numbers 4 can make the trainees feel the angle and position of the serve more intuitively; the outer circumferential surface of the striking wheel 3 is provided with a rubber coating 5 to increase the friction of striking the ball.

[0015] The supporting device is in a K-shaped structure as a whole, the bottom of the main support rod 11 is connected to the base 1 through a rotating shaft, one end of the two oblique support rods 12 is connected to the middle of the main support rod 11 through a rotating shaft, and the other ends are respectively connected to the base 1 and the slide rail 2 through the rotating shaft. The K-shaped structure forms two triangular structures at the upper and lower parts, making the overall structure more stable.
