Description
Technical Field
[0001] This invention relates to the field of sports equipment, and more particularly to a tennis training wall. Background Technology
[0002] In tennis training, tennis practice walls are often used to develop "ball control" or "ball feel." Practitioners judge the trajectory of the ball based on the angle of its bounce, move their feet, find the right hitting point, and train the coordination between their eyes, hands, feet, and racket. Traditional tennis practice walls are flat, and it is easy to judge the angle and trajectory of the ball when it bounces back. The training effect is quite different from that of actual combat. A device is needed to solve the above problems. Summary of the Invention
[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a tennis training wall consisting of a set of catapult plates that can rotate back and forth in multiple directions, exhibiting strong randomness in the trajectory of tennis balls bouncing back, simulating real-world combat effects, and providing a powerful training effect.
[0004] The objective of this invention is achieved through the following technical solution:
[0005] A tennis training wall includes a base, the base being rotatably connected to a set of multi-directionally rotatable launch plates, the launch plates being driven by a reciprocating drive frame; a support frame is provided on the upper part of the base, the bottom of the support frame has a horizontal groove, and the upper part of the horizontal groove has a set of vertical grooves, the horizontal grooves and the set of vertical grooves are spaced apart and fill the interior of the support frame, a set of horizontal launch plates is provided inside the horizontal grooves, and a set of vertical launch plates is provided inside each vertical groove, the horizontal and vertical launch plates filling the interior of the base forming a tennis training wall; each horizontal groove has The beam has a set of transverse wheel grooves inside, each with a transverse wheel groove hole in the middle. Each transverse catapult plate shaft passes through the corresponding transverse wheel groove hole and the first pulley. The transverse catapult plate shaft is rotatably connected to the corresponding transverse wheel groove hole and is fixedly connected to the corresponding first pulley. Each transverse wheel groove has a transverse groove bearing seat on its rear side. Each transverse groove bearing seat is rotatably connected to the intermediate shaft of the second pulley. The second pulley and the corresponding first pulley are rotatably connected to the first belt on their outer sides. Each second pulley intermediate shaft has a gear fixedly connected to its upper part.
[0006] The vertical groove side beam has a set of vertical wheel grooves inside, each vertical wheel groove has a vertical wheel groove hole in the middle, each vertical catapult plate shaft passes through the corresponding vertical wheel groove hole and the No. 3 pulley, the vertical catapult plate shaft is rotatably connected to the corresponding vertical wheel groove hole, the vertical catapult plate shaft is fixedly connected to the corresponding No. 3 pulley, each vertical wheel groove has a vertical groove bearing seat on the rear side, each vertical groove bearing seat is rotatably connected to the No. 4 pulley intermediate shaft, the corresponding No. 3 pulley and No. 4 pulley are rotatably connected to the No. 2 belt on the outside, each No. 4 pulley intermediate shaft is rotatably connected to the No. 2 bevel gear on the outside, the upper side bearing seat of each vertical groove bearing seat is rotatably connected to the No. 1 bevel gear intermediate shaft, the No. 1 bevel gear and the No. 2 bevel gear mesh with each other, and a gear is fixedly connected to the upper part of each No. 1 bevel gear intermediate shaft.
[0007] Beneficial effects: When using this device, starting the motor causes the drive frame to reciprocate. During this reciprocating motion, the rack drives its respective gears, which in turn cause the horizontal launch plates to rotate around their vertical axes. Horizontally adjacent horizontal launch plates rotate in opposite directions, and vertically adjacent horizontal launch plates also rotate in opposite directions. This set of horizontal launch plates causes the tennis ball to bounce horizontally to the left and right. Because the angle of the horizontal launch plates is uncertain at any given time, and the landing point of the tennis ball is unpredictable, the angle at which the tennis ball bounces back in the left and right directions is highly random. Similarly, the gears in the vertical slots drive the vertical launch plates to rotate around their respective horizontal axes. Horizontally adjacent vertical launch plates rotate in opposite directions, and vertically adjacent vertical launch plates also rotate in opposite directions. This set of vertical launch plates causes the tennis ball to bounce vertically up and down. Because the angle of the vertical launch plates is uncertain at any given time, and the landing point of the tennis ball is unpredictable, the angle at which the tennis ball bounces back in the up and down directions is highly random. The tennis wall formed by the horizontal and vertical launch plates makes the direction and angle of the tennis ball's rebound highly random, effectively simulating real-world combat and providing strong training results.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
[0015] refer to Figure 1 , 2 3. A tennis training wall, comprising a base 110, wherein the base 110 is rotatably connected to a set of launch plates that can rotate in multiple directions, the set of launch plates being driven by a reciprocating drive frame 130.
[0016] refer to Figure 4 , 5 The base 110 is provided with a support frame 111 on the upper part. The support frame 111 is provided with a horizontal groove 112 at the bottom. The horizontal groove 112 is provided with a set of vertical grooves 115 on the upper part. The horizontal groove 112 and the set of vertical grooves 115 are arranged alternately to fill the interior of the support frame 111. The horizontal groove 112 is provided with a set of horizontal ejector plates 280. Each vertical groove 115 is provided with a vertical ejector plate 290. The horizontal ejector plates 280 and vertical ejector plates 290 filling the interior of the base 110 form a tennis training wall.
[0017] refer to Figure 4 , 5 Each transverse groove 112 has a set of transverse wheel grooves 113 inside the upper beam. Each transverse wheel groove 113 has a transverse wheel groove hole 114 in the middle. The shaft of each transverse ejector plate 280 passes through the corresponding transverse wheel groove hole 114 and the first pulley 180. The shaft of the transverse ejector plate 280 is rotatably connected to the corresponding transverse wheel groove hole 114. The shaft of the transverse ejector plate 280 is fixedly connected to the corresponding first pulley 180. Each transverse wheel groove 113 has a transverse groove bearing seat 118 on the rear side. Each transverse groove bearing seat 118 is rotatably connected to the intermediate shaft of the second pulley 210. The second pulley 210 and the corresponding first pulley 180 are rotatably connected to the outer side of the first belt 190. Each second pulley 210 has a gear 250 fixedly connected to the upper part of the intermediate shaft. When gear 250 rotates, it drives pulley 210, which is fixedly connected to it, to rotate. Pulley 210 drives pulley 180 to rotate via belt 190. Pulley 180 drives horizontal ejector plate 280, which is fixedly connected to it, to rotate. Horizontal ejector plate 280 rotates around its own vertical axis.
[0018] refer to Figure 4 , 5The side beam of the vertical groove 115 has a set of vertical wheel grooves 116 inside, and each vertical wheel groove 116 has a vertical wheel groove hole 117 in the middle. The rotating shaft of each vertical catapult plate 290 passes through the corresponding vertical wheel groove hole 117 and the No. 3 pulley 220. The rotating shaft of the vertical catapult plate 290 is rotatably connected to the corresponding vertical wheel groove hole 117, and the rotating shaft of the vertical catapult plate 290 is fixedly connected to the corresponding No. 3 pulley 220. Each vertical wheel groove 116 has a vertical groove bearing seat 119 on its rear side. Each vertical groove bearing seat 119 rotates... The intermediate shaft of pulley 240 is movably connected to the fourth pulley. The outer sides of pulley 220 and pulley 240 are rotatably connected to belt 230. The outer side of the intermediate shaft of each pulley 240 is rotatably connected to bevel gear 270. The side bearing seat 120 on the upper part of each vertical groove bearing seat 119 is rotatably connected to the intermediate shaft of bevel gear 260. The bevel gear 260 and bevel gear 270 mesh with each other. A gear 250 is fixedly connected to the upper part of the intermediate shaft of each bevel gear 260. When gear 250 rotates, it drives bevel gear 260, which is fixedly connected to it, to rotate. The rotation of bevel gear 260 drives bevel gear 270 to rotate. The rotation of bevel gear 270 drives pulley 240, which is fixedly connected to it, to rotate. Pulley 240 drives pulley 220 to rotate via belt 230. Pulley 220 drives vertical catapult plate 290 to rotate. Vertical catapult plate 290 rotates around its horizontal axis.
[0019] refer to Figure 6 The drive frame 130 has a set of rack frames 132 on its inner side. These rack frames 132, from bottom to top, correspond sequentially to mutually spaced horizontal slots 112 and vertical slots 115. Each rack frame 132 is engaged with both sides of a set of gears 250 within the corresponding horizontal slot 112 and vertical slot 115. (Reference) Figure 6 The rack frame 132 has a U-shaped structure. Each of the two long sides of the U-shape contains a set of racks 133. The racks 133 on the two long sides of the same rack frame 132 are arranged crosswise. The racks 133 are respectively positioned on both sides of adjacent gears 250 and mesh with them. Adjacent gears 250 rotate in opposite directions. (Reference) Figure 6 The racks 133 inside the rack frame 132 corresponding to the transverse slot 112 are arranged in a crisscross pattern from top to bottom, so that the gears 250 inside two adjacent transverse slots 112 in the vertical direction turn in opposite directions.
[0020] refer to Figure 6 The racks 133 inside the rack frame 132 corresponding to the vertical slot 115 are arranged in a crisscross pattern from top to bottom, so that adjacent gears 250 in the vertical direction turn in opposite directions.
[0021] refer to Figure 6The dovetail block 131 at the lower part of the drive frame 130 is slidably connected to the dovetail groove 121 on one side of the base 110. A spring 170 is connected between the spring plate 124 on the side of the drive frame 130 and the side of the dovetail groove 121. A cam 150 is slidably connected to the side of the drive frame 130. The intermediate shaft of the cam 150 is rotatably connected to the cam seat 122 on the rear side of the side bearing seat 120. The intermediate shaft of the cam 150 is connected to the output shaft of the motor 160. The motor 160 is fixedly connected to the motor plate 123 on the side of the cam seat 122. When the motor 160 drives the cam 150 to rotate, the cam 150 and the spring 170 work together to make the drive frame 130 reciprocate. The reciprocating motion of the drive frame 130 causes the gear 250 to move back and forth.
[0022] When using this device, the motor 160 is started, and the drive frame 130 reciprocates. During this reciprocating motion, the rack 133 drives its respective gears 250 to reciprocate. The gears 250 within the transverse groove 112 drive their respective horizontal ejector plates 280 to rotate back and forth around their vertical axes. Horizontally adjacent horizontal ejector plates 280 rotate in opposite directions, and vertically adjacent horizontal ejector plates 280 also rotate in opposite directions. A set of horizontal ejector plates 280 causes the tennis ball to bounce horizontally to the left and right. Because the angle of the horizontal ejector plate 280 is not fixed at any given time, and the landing point of the tennis ball is uncertain, the angle at which the tennis ball bounces back in the left and right directions has a great degree of variation. The randomness is achieved by the gears 250 inside the vertical slot 115 driving each vertical catapult plate 290 to rotate back and forth around its own horizontal axis. Adjacent vertical catapult plates 290 in the horizontal direction rotate in opposite directions, and two adjacent vertical catapult plates 290 in the vertical direction also rotate in opposite directions. A set of vertical catapult plates 290 causes the tennis ball to bounce back vertically. Since the angle of the vertical catapult plate 290 is not fixed at any given time, and the landing point of the tennis ball is uncertain, the angle at which the tennis ball is bounced back in the vertical direction has great randomness. The tennis wall formed by the horizontal catapult plate 280 and the vertical catapult plate 290 makes the direction and angle of the tennis ball's rebound extremely random, which simulates the effect of actual combat and has a strong training effect.
