Description

Technical fields:

[0001] This utility model relates to the field of table tennis ball serving equipment manufacturing technology, specifically a vertical lifting table tennis ball serving machine with reasonable structure, simple operation, and the ability to expand the ball release position of the ball serving machine head, thereby helping to improve training level. Background technology:

[0002] Currently, table tennis ball serving machines are essential entertainment and training tools for many families and table tennis halls. Table tennis ball serving machines are suitable for use in communities, schools, homes, and professional training venues; they can be used for both recreational fitness and professional training, offering excellent value for money. However, existing table tennis ball serving machines still have some shortcomings. Their fixed position relative to the table makes them inconvenient to move, and the fixed height of the machine head results in a less than satisfactory simulation effect, failing to mimic the human playing process and thus not meeting the requirements of those who want to play in matches. Summary of the Invention:

[0003] This invention addresses the shortcomings and deficiencies of existing technologies by proposing a vertical lifting table tennis ball serving machine that is structurally sound, easy to operate, and facilitates mimicking human actions at different striking points, reducing the ball's trajectory, and exhibiting more human-like and realistic ball characteristics during actual play.

[0004] This utility model achieves its purpose through the following measures:

[0005] A vertical lifting table tennis ball serving machine is provided, comprising a ball serving machine, a support frame, and a lifting mechanism. The support frame includes a base plate and a support body fixed to the base plate. The support body includes four columns connected by a crossbeam. The front side of the support body corresponds to the ball-ejecting side of the ball serving machine head. The ball serving machine is installed in the support frame via the lifting mechanism. The lifting mechanism includes a chain lifting assembly and a lifting guide assembly. The lifting guide assembly includes a guide rail arranged along the columns, and a slider cooperating with the guide rail is provided on the guide rail. The slider is connected to the ball serving machine. The chain lifting assembly is connected to the ball serving machine.

[0006] The chain lifting assembly of this utility model includes a driving sprocket, a driven sprocket, a geared motor, and a chain. The driving sprocket and the driven sprocket are respectively installed at the upper and lower ends of the support frame. The geared motor drives the driving sprocket to rotate, thereby driving the ball-serving machine connected to the chain to rise and fall. The geared motor is controlled by the control board in the ball-serving machine. When the ball-serving machine wants to serve different balls, the geared motor automatically drives the sprocket to rotate, causing the ball-serving machine to rise and fall to the set height position, realizing one-click access to various ball serves.

[0007] The four columns of the support frame of this utility model are respectively provided with lifting guide components, wherein the lifting guide components on the two columns on the rear side of the support frame also include guide rails arranged along the columns and sliders that cooperate with the guide rails.

[0008] This utility model also includes a counterweight assembly, which includes a counterweight block connected to the chain in the chain lifting assembly and disposed on the rear side of the support frame and the rear side of the ball-serving machine. This is used to improve the lifting stability and accuracy of the ball-serving machine. Furthermore, the counterweight assembly also includes a lifting guide assembly that cooperates with the counterweight block. The lifting guide assembly includes vertical guide rails disposed on two columns on the rear side of the support frame and two sliders that cooperate with the vertical guide rails respectively. The two sliders are respectively connected to the counterweight block to ensure the stability of the lifting of the counterweight block and prevent swaying.

[0009] In the chain lifting assembly of this utility model, the reduction motor is mounted on the base plate, and the drive sprocket is mounted on the lower end of the support frame to improve the bottom stability of the entire device.

[0010] This utility model also includes a ball-collecting assembly, which includes a wing net and a large hanging frame. The wing net is installed on both sides of the support frame through a wing net bracket, and the large hanging frame is installed at the rear of the support frame. A ball-blocking net is hung on the large hanging frame and connected to the wing net, together forming the entire ball-collecting assembly, which is used to intercept and collect the ping-pong balls hit by the opponent and supply them to the ball-serving machine so that the ball-serving machine can serve continuously.

[0011] This utility model also includes a moving component, which includes casters. Four casters are installed at the bottom of the support frame to facilitate the movement of the entire vertical lifting ball machine.

[0012] The movable component of this utility model also includes an eccentric wheel drive motor. The eccentric wheel drive motor is a dual-output shaft motor, which is connected to two eccentric wheels located on both sides of the bottom of the support frame via a transmission shaft. The two eccentric wheels are respectively installed in the middle of a pair of caster rockers. The casters are installed at the lower end of the caster rockers. By rotating the eccentric wheels, the height of the casters can be adjusted by the caster rockers, so that the casters can be retracted or lowered. Thus, when the frame body is lowered, the casters are retracted, and the bottom plate of the support frame is lowered smoothly, ensuring the stability of the ball machine. When the casters are lowered, the frame body drives the entire lifting ball machine to move more conveniently.

[0013] Compared with the prior art, this utility model expands the ball-launching position of the table tennis ball-serving machine relative to the table through a chain-type lifting component. The ball-serving machine has a novel and stable structure and is easy to operate. It can not only realize the functions of all existing ball machines on the market, but also help to imitate the human to complete different hitting points, reduce the ball-launching arc of the ball machine, and more humanize and closely resemble the various ball characteristics exhibited in real match situations.
