Description

Technical Field

[0001] This utility model belongs to the field of sports equipment technology, specifically relating to an automatic ball-collecting device for a ping-pong ball collecting net. Background Technology

[0002] Table tennis is a captivating and influential sport with a long history, simple and easy-to-understand rules, and a rich variety of techniques. With the development and expansion of international sports events, table tennis has a promising future. During training, players typically prepare dozens or even hundreds of table tennis balls for use. Balls missed by players often scatter in various corners. Currently, to prevent excessive ball drop, a collecting net is often placed behind the table to intercept and collect the balls. Existing table tennis nets consist of a frame and a net attached to it. The net includes a shielding section and a ball-catching section at the bottom. The ball-catching section is an upward-facing net groove where the table tennis ball eventually falls. After a game, players need to retrieve the ball from the net groove for the next training session, which is time-consuming and laborious. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an automatic ball-collecting device for a ping-pong ball collecting net, so as to collect ping-pong balls and reduce the time players spend retrieving balls, thus saving their energy.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] An automatic ball-collecting device for ping-pong balls includes a frame, a ball-blocking net, a base plate, a ball-collecting pocket, and a suction mechanism. The frame includes a body and legs connected to the lower sides of the body. The ball-blocking net includes a front net and a rear net. The upper end of the rear net is located in the middle of the frame, and its side is connected to the frame. The lower end of the rear net and the front net are connected to the legs. The upper edge of the rear net is higher than the upper edge of the front net, which is used to block the ping-pong ball so that it falls between the front and rear nets. The base plate is inclinedly connected to the two legs and is located between the front and rear nets. The lower edges of the front and rear nets are connected to the front and rear sides of the base plate, respectively. The ball-collecting pocket is located on the lower side of the base plate, and its upper end is open, with the opening being lower than or flush with the base plate. The suction mechanism is located on the side of the frame and above the ball-collecting pocket, and is used to suction the ping-pong ball.

[0006] Furthermore, the suction mechanism includes a guide tube, a vacuum pump, a suction box, and a venting tube. One end of the guide tube is connected to the lower end of the ball collection bag, the suction box is located above the ball collection bag, the other end of the guide tube is connected to the suction box, the suction port of the vacuum pump is connected to the suction box, the upper end of the venting tube is connected to the suction box, and the lower end of the venting tube is higher than the upper end of the ball collection bag.

[0007] Furthermore, a basin rack is provided on the side of the frame, and a ball collecting basin is provided on the basin rack. The ball collecting basin is located at the lower end of the volleyball tube, and the ping-pong balls can be sucked into the ball collecting basin for easy access.

[0008] Furthermore, the lower end of the ball suction box is located on an inclined surface, the upper end of the ball guide tube is connected to the upper end of the inclined surface, and the ball volleyball tube is connected to the lower end of the inclined surface, so that the ping-pong ball can be discharged from the ball volleyball tube.

[0009] Furthermore, a vacuum pump is connected to the upper end of the ball suction box, and the vacuum pump is located between the ball guide tube and the ball volley tube, so that the ping-pong ball coming out of the ball guide tube is subjected to a suction force in the direction of the ball volley tube, which helps to prevent it from falling back into the ball guide tube.

[0010] Furthermore, a V-shaped groove is formed between the lower end of the rear net, the front net, and the base plate, which facilitates the gathering of ping-pong balls on the base plate and their sliding down the base plate.

[0011] Furthermore, the ball collecting bag is funnel-shaped, wider at the top and narrower at the bottom, to collect ping-pong balls.

[0012] Furthermore, the leg frame includes a high support leg and a low support leg, which are connected to the front side of the frame. The high end of the base plate is connected to the high support leg, and the low end of the base plate is connected to the low support leg. This can stably support the frame and facilitate the connection of the base plate, allowing the base plate to be in an inclined state.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. After the ping-pong ball is blocked by the rear net, it will fall between the lower ends of the front and rear nets and eventually roll into the ball collection bag under the action of gravity along the inclined bottom plate. Compared with the existing technology, the inclined bottom plate replaces the bottom horizontal net groove, eliminating the need to manually scoop the ping-pong ball out of the net groove, thus saving time and effort.

[0015] 2. The vacuum pump of the suction mechanism can suck the ping-pong ball upwards, and after passing through the ball suction box, the ping-pong ball is discharged from the ball tube. By placing a ball collection basin under the ball tube, the ping-pong ball can be collected without having to bend over to pick it up, which is more convenient. Attached Figure Description
