Description

Technical Field

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

[0002] Tennis and table tennis are very popular sports. Tennis topspin and table tennis loops are achieved by hitting with topspin and force to increase the ball's linear velocity and angular velocity. In order to ensure that students can hit the ball quickly, deeply and stably, the most basic technique is to learn to exert force along the arc direction on the circumference, but the force point should be adjusted according to the rotation of the incoming ball. If the incoming ball is a topspin ball, the hitting position is about from the 10 o'clock position to the 11 o'clock position on the clock, and the hitting point should be fine-tuned according to the actual situation when practicing. However, there is no corresponding training equipment in the existing training equipment, and students can only rely on themselves to explore the angle for practice, which leads to slow progress in students' ball learning skills. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a swing-type tennis and table tennis powerful topspin training device, which adopts a swing 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.

[0004] In order to solve the above problems, the specific technical solutions of the utility model are as follows: a swing-type tennis and table tennis powerful topspin trainer, a support adjustment device is provided on the base, a swing rod is connected to the top of the support adjustment device through a first axis, the top of the swing rod is connected to the striking wheel through a bearing, the bottom of the swing rod is connected to the base through an elastic structure, and when the swing rod is in a stationary state, the swing rod is at an angle of 30° to 60° with the horizontal plane; clock numbers are provided on the surface of the striking wheel.

[0005] The support adjustment device includes a main bracket and an oblique support rod; the bottom end of the oblique support rod is movably connected to the base through a third axis; the bottom end of the main bracket is movably connected to the base through a second axis; a plurality of adjustment holes are respectively provided on the tops of the main bracket and the oblique support rod, and one of the adjustment holes of the main bracket is coaxial with another adjustment hole of the main bracket and is coaxially connected with the first axis.

[0006] The elastic structure is two latex high-elastic rubber bands of different lengths. A through hole is provided at the bottom of the swing rod. The shorter latex high-elastic rubber band passes through the through hole and is fixed to the right side of the base, and the longer latex high-elastic rubber band passes through the through hole and is fixed to the left side of the base.

[0007] A long hole is arranged on the top of the swing rod, and the central bearing of the striking wheel is adjusted and positioned in the long hole by means of bolts.

[0008] The outer circumferential surface of the striking wheel is provided with a rubber coating.

[0009] A shock-absorbing and anti-skid pad is provided at the bottom of the base.

[0010] The swing-type 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 swing amplitude of the swing rod, so that the coach can more intuitively judge the student's action and provide more standardized action guidance.

[0012] Figure 2 The present invention is a three-dimensional picture of a swing-type tennis and table tennis powerful topspin trainer. DETAILED DESCRIPTION

[0013] like Figure 1 and Figure 2 As shown, a swing-type tennis and table tennis strong topspin trainer is provided on a base 1. A support adjustment device is provided on the top of the support adjustment device, and a swing rod 4 is connected to the top of the swing rod 4 through a first shaft 11. The top of the swing rod 4 is connected to the striking wheel 5 through a bearing. The outer circumferential surface of the striking wheel 5 is provided with a rubber coating 9 to increase the friction of striking. The bottom of the swing rod 4 is connected to the base 1 through an elastic structure, and when the swing rod 4 is in a stationary state, the swing rod 4 forms an angle of 30° to 60° with the horizontal plane. A clock number 6 is provided on the surface of the striking wheel 5. When used, the clock number 6 is reset to the digital position of the clock, and the striking position and angle are judged by the number.

[0014] The support adjustment device comprises a main support 2 and an oblique support rod 3; the bottom end of the oblique support rod 3 is movably connected to the base 1 through a third shaft 13; the bottom end of the main support 2 is movably connected to the base 1 through a second shaft 12; the tops of the main support 2 and the oblique support rod 3 are respectively provided with a plurality of adjustment holes 7, one of the adjustment holes 7 of the main support 2 is coaxial with one of the adjustment holes 7 of the main support 2, and is coaxially connected with the first shaft 11, such as Figure 2 As shown, the main bracket 2 adopts a two-piece structure arranged in parallel, the swing rod 4 also adopts a two-piece structure arranged in parallel, and the oblique support rod 3 is a single-piece structure, so that two swing rods 4 can be sandwiched between two main brackets 2, and the oblique support rod 3 can be sandwiched between two swing rods 4, so as to achieve structural stability. The support adjustment device can be adjusted in height by adjusting the position of the hole, so that students of different heights can choose the training height according to their own conditions.

[0015] The elastic structure is two latex high elastic rubber bands 8 of different lengths. A through hole is provided at the bottom of the swing rod 4. The shorter latex high elastic rubber band 8 passes through the through hole and is fixed to the right side of the base 1, and the longer latex high elastic rubber band 8 passes through the through hole and is fixed to the left side of the base 1. The use of the latex high elastic rubber band 8 is not only low in cost, but also the angle of the swing rod 4 can be adjusted by adjusting the length, which is convenient to use.

[0016] The top of the swing rod 4 is provided with a long hole, and the central bearing of the striking wheel 5 is adjusted and positioned in the long hole by bolts, so that the height of the striking wheel 5 can be slightly adjusted.

[0017] A shock-absorbing and anti-skid pad 10 is provided at the bottom of the base 1 to improve the anti-skid performance of the entire device.

[0018] When the swing-type tennis and table tennis powerful topspin training device of the present application is used, the position between 10 and 11 o'clock on the clock is hit according to the position of the clock number 6 to complete the topspin training.
