Embodiment 1

[0022] see Figure 1-3 , a kind of main-spin ball serving device for table tennis training, comprising a base 1, a power hammer box 2 positioned on the base 1, a serving cylinder 3 positioned above the power hammer box 2 and connected, and a The delivery box 5, the serving cylinder 3 are used to send out a single ball, and the power hammer box 2 is used to output power to a single ball in the serving cylinder 3. The bottom of the serving cylinder 3 is provided with an open cavity 31 for connecting with the power hammer box 2 Internally communicated, the power hammer box 2 and the serving cylinder 3 are both cylindrical and arranged perpendicularly to each other. A ball spinner 4 is located at the top surface and the side of the serving cylinder 3 respectively, and the ball spinner 4 includes a body in which a speed-changing motor 41 is fixed, and the output end of the speed-changing motor 41 is provided with a half bevel gear 42. Also be provided with the disk driving lever 4...

Embodiment 2

[0025] refer to Figure 4 , Figure 5 , and the difference from Embodiment 1 is that, in order to ensure the quantitative single entry of table tennis balls and avoid the one-time entry of multiple table tennis balls in the serving cylinder 3 to affect the serving effect, the delivery box 5 includes a box body 51, and is placed in the box body A low-speed motor 52 is arranged in the center of the inner top surface of the 51, and the box body 51 is cylindrical in shape. The output end of the low-speed motor 52 is connected with a rotating shaft 53, and the lower end of the rotating shaft 53 is fixed to fit and slide on the bottom surface of the box body 51. Connect the opening disc 54, the opening disc 54 is provided with a quantitative opening 55, the top of the serving cylinder 3 is provided with a ball inlet 33 connected to the inside of the box body 51, the ball inlet 33 is located directly above the positioning device 32, when working, the box body 51 A plurality of table...

Abstract

The invention discloses an autonomous ball spinning and serving device for table tennis training. The autonomous ball spinning and serving device for table tennis training comprises a base, a power hammer box, a ball serving barrel and a conveying box, wherein the power hammer box is positioned on the base; the ball serving barrel is positioned on the power hammer box and communicates with the power hammer box; the conveying box is fixed on the ball serving barrel; an open cavity which communicates with the inside of the power hammer box is formed in the bottom of the ball serving barrel; thepower hammer box and the ball serving barrel are cylindrical and are perpendicular to each other; and a front side surface of the ball serving barrel has an opening structure. Two ball spinning devices are arranged on the front side of the ball serving barrel, therefore, when table tennis balls are sprayed out from the front end of the ball serving barrel, a side surface of a ball spinning plate rubs with the table tennis balls, a rotating effect is applied to the table tennis balls, thus, the training effect is improved, moreover, the ball spinning plate rotates in a reciprocating manner, therotating effects of the table tennis balls are different, meanwhile, the rotating intensity can also be increased or reduced by changing the rotating speed of a variable-speed motor, and the two ballspinning devices at different positions can simulate various rotating angles so as to ensure training comprehensiveness.

Description

technical field [0001] The invention relates to sports equipment, in particular to a main spin ball serving device for table tennis training. Background technique [0002] Table tennis is China's national ball game and a popular ball sport in the world. It is a whole-body exercise that strengthens the body, brain and heart. The conditions for its development are not harsh, and it is highly accessible, so it has a high degree of popularity. . [0003] Although the conditions for developing table tennis are relatively convenient, two people are required for routine training, and when professional training is required, it is necessary to strengthen the strength and habits of practice, often using a ball machine. [0004] At present, there are many kinds of ball machines on the market, and most of the table tennis ball serving mechanisms currently use the pneumatic impact mode to serve the ball, but the problem is that the pneumatic type often causes the table tennis ball to ru...
