Abstract
Description
Technical Field
[0001] The utility model relates to a sports apparatus, in particular to a table tennis hitting point trainer for practicing table tennis techniques. Background Art
[0002] The landing point of a table tennis shot refers to the point where the hitter hits the ball onto the opponent's table by legal means, that is, the landing point. In a table tennis match, if the player's hitting point is tricky and changeable, he can mobilize and control the opponent, thereby taking the initiative and winning. Therefore, enhancing the awareness of the landing point and improving the ability to control the landing point are not only conducive to improving the quality of the shot, but also conducive to increasing the tactical effect. The main training methods for improving the ability to control and change the landing point are: when athletes are practicing various basic techniques, they are required to hit the ball into the area drawn with lines, and the practice method of placing objects as hitting targets. The shortcomings of these two training methods are: the practice method of drawing the area is used, because the area target drawn is not three-dimensional and not obvious, so the training effect is not good. The practice method of placing objects as hitting targets is a better practice method, but there is currently no suitable object that can be used as a device for practicing the landing point of table tennis shots.

[0022] The fixing assembly serves to fix the trainer on the table tennis table, and at the same time serves to connect with the outer square tube 9. The outer square tube 9 and the inner square tube 10 connect the fixing assembly and the round frame 11. The net frame 12 hung on the round frame 11 can catch the dropped ball when the athlete is practicing hitting the ball. The athlete can use this trainer to perform fixed-point or fixed-area exercises.
[0023] The fixing assembly includes a clamping plate 2, an axle rod 4, a U-piece 7, and a positioning device 3. The lower plate of the clamping plate 2 is provided with a first fixing device 1. The upper end of the upper plate of the clamping plate 2 is fixedly connected to the axle rod 4. The outside of the axle rod 4 is provided with a U-piece 7. The ring plate of the U-piece 7 is provided with a through hole corresponding to the groove on the axle rod 4. The U-piece 7 is connected to the axle rod 4 through the positioning device 3.
[0024] Two pairs of through holes are provided on the two straight plates of the U-piece 7, and the second fixing device 8 fixes and connects the U-piece 7 and the outer square tube 9 through the through holes.
[0025] The circular frame 11 is connected with a screen frame 12.
[0026] The clamp plate 2 and the first fixing device 1 are used to fix the exerciser on the table tennis table, and the positioning device 3 is used to fix the U-piece 7 and the shaft rod 4. The U-piece 7 is used to connect with the outer square tube 9 as a part of the fixing assembly.
[0027] like Figure 2 As shown, the shaft rod 4 is sleeved with a rolling bearing 17, and the rolling bearing 17 is provided with a corresponding sleeve 6 on the outside, and the sleeve 6 is fixed to the shaft rod 4 by a fastening device 5; the rolling bearing 17 can control the orientation of the U-piece 7 by rolling, and the positions of the round frame 11 and the net frame 12 are adjusted by changing the orientation of the U-piece 7, so as to facilitate athletes to perform fixed-point or fixed-area exercises; the sleeve 6 can reduce the loss caused by the friction between the rolling bearing 17 and the shaft rod 4.
[0028] The positioning device 3 includes a spring 13, a positioning pin 14, a pressure cap 15, and a sleeve 16. The positioning pin 14 corresponds to the groove on the shaft rod 4. The spring 13 is provided with a sleeve 16 corresponding thereto. The positioning pin 14 passes through the spring 13 and is connected to the shaft rod 4. The pressure cap 15 fixes the sleeve 16 and the positioning pin 14. The positioning device 3 plays a role in fixing the shaft rod 4 and the U-piece 7.

By sleeve-connecting any two pairs of through holes on the inner square tube 10 with one end of the outer square tube 9, the length of the connection between the outer square tube 9 and the inner square tube 10 can be controlled.
[0030] By extending and retracting the inner square tube 10, the positions of the round frame 11 and the net frame 12 can be controlled, so that athletes can perform fixed-point or fixed-area exercises.
[0031] like Figure 3 As shown, after the overall assembly is completed, when in use, according to the needs of practice and teaching, the table tennis hitting point training device is fixed on the table tennis table. According to the needs of the practice content, the position of the net frame 12 is changed by stretching the inner square tube 10, so that the athlete can practice fixed-point or fixed-area exercises. When a small part of the inner square tube 10 is retracted into the outer square tube 9, the athlete can practice fixed-point shots or fixed-area shots on the right side of the opposite table; when most of the inner square tube 10 is retracted into the outer square tube 9, the athlete can practice fixed-point shots or fixed-area shots on the left side of the opposite table; adjusting the length of the inner square tube 10 outside can adjust the circular frame 11 to the center line of the table, which is convenient for athletes to practice straight shots.
[0032] By adjusting the angle of the outer square tube 9, the height of the net frame 12 can be adjusted, which is convenient for athletes to perform fixed-point or fixed-area exercises. When adjusting the angle of the outer square tube 9, the second fixing device 8 needs to be removed. After adjusting the angle, the outer square tube 9 and the U-piece 7 are re-fixed with the second fixing device 8.
[0033] By rotating the shaft sleeve 6, the position of the net frame 12 can be adjusted, so that athletes can perform fixed-point or fixed-area exercises.
[0034] Furthermore, the first fixing device 1 is a fixing bolt.
[0035] Furthermore, the second fixing device 8 is a fixing bolt.
[0036] Furthermore, the fastening device 5 is a fastening nut.
[0037] Example 1: Figure 3 As shown, the table tennis ball hitting point trainer is fixed near the table tennis table net, and the trainer uses the trainer to assist in various technical exercises. For example, in the serving technique exercise, the trainer serves the ball to the net frame near the end line of the table, and practices the ability to control and change the landing point when serving various spinning balls.
[0038] Embodiment 2: The trainer uses the trainer to assist in practicing returning various spinning balls. For example, in ball receiving technique practice, the coach stands on the side of the table and continuously sends various spinning balls to the athletes, and the athletes return the balls to the net frame of the trainer to practice the ability to control and change the landing point when returning various spinning balls.
[0039] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Those skilled in the art can still adjust the technical solutions recorded in the above embodiments, or replace some of the technical features by equivalents.
