Technical Field

[0001] This utility model relates to the field of table tennis training equipment manufacturing technology, specifically a table tennis conveying device and table tennis serving equipment with reasonable structure and simple assembly, which can meet the needs of continuous and stable conveying during table tennis serving training. Background Technology

[0002] Table tennis serving equipment requires feeding ping-pong balls one by one from a ball storage device to a ball launcher, which then launches the ball. Ensuring a continuous and stable ball supply is crucial during training. Currently, the main ball delivery lane of such equipment has a relatively simple structure. When deformed or damaged ping-pong balls are present in the ball storage pool, they cannot be removed promptly, leading to a decline in serving quality and failing to meet professional training requirements.

[0003] In addition, the existing table tennis serving equipment has a simple suspension clamping mechanism, which is prone to loosening and displacement during use, affecting the quality and continuity of the serve. Summary of the Invention

[0004] This utility model addresses the shortcomings and deficiencies of existing technologies by proposing a table tennis ball conveying device and table tennis ball serving equipment that has a reasonable structure, is easy to assemble, and can meet the needs of continuous and stable conveying during table tennis serving training.

[0005] This utility model achieves its purpose through the following measures:

[0006] A ping-pong ball conveying device includes a main lane, the upper end of which is connected to a ball outlet pipe, and the lower part of the main lane has a horizontal pipe section for connecting to a ball storage pool. The device is characterized in that a vertical pipe section below the horizontal pipe section on the main lane is a ball return pipe section, and a vertical pipe section above the horizontal pipe section is a ball delivery pipe section. The main lane also includes a ball entry / return assembly, which includes a ball deflector and a driving component for rotating the deflector. The ball entry / return deflector is located inside the main lane and is disposed on the inner wall of the main lane opposite to the horizontal pipe section. The rear end of the ball entry / return deflector is connected via a pivot to the driving component located outside the main lane. The driving component drives the ball entry / return deflector to rotate, connecting the horizontal pipe section and the ball delivery pipe section to deliver the ball, or connecting the horizontal pipe section and the ball return pipe section to return the ball.

[0007] The main body of the ball advance / retreat paddle of this utility model is arc-shaped, and further, the upper surface of the paddle main body has an inner concave portion adapted to the ping-pong ball.

[0008] The drive component of this utility model adopts a ball infeed / return drive motor and a gearbox (transmission). The ball infeed / return drive motor and the gearbox drive the rotation of the shaft connected to the rear end of the ball infeed / return paddle, thereby completing the switching between the ball return track and the ball delivery track.

[0009] This utility model also proposes a table tennis ball serving device, which is equipped with a ball serving machine head and a table tennis ball conveying device as described above. The ball serving machine head is installed at the upper end of the main ball lane in the table tennis ball conveying device.

[0010] In this invention, the ball machine head is connected to the upper end of the main lane via a plug-in locking structure. There are two symmetrically distributed wedge-shaped protrusions at both the upper and lower ends of the main lane, and correspondingly, there are two grooves on the machine head and the ball storage base. The upper and lower ends of the main lane are inserted into the corresponding grooves and tightened clockwise, and loosened counterclockwise. During assembly, the ball machine head can be easily installed on the main lane, and disassembly is also very simple.

[0011] This utility model also includes a ball storage base for serving as a ball storage pool. The ball storage base has a box with an open top for holding ping-pong balls to be transported. The box contains a ball supply assembly, which includes a ball supply motor and a ball supply impeller. The blades of the ball supply impeller propel the ping-pong balls into the inlet of the horizontal pipe section. The ball supply motor drives the ball supply impeller to rotate.

[0012] Furthermore, the side of the ball storage base is also provided with a lithium battery box for accommodating lithium batteries. In order to improve the support stability of the equipment, pull-out lithium battery boxes for accommodating lithium batteries can be symmetrically provided on both sides of the box, making the base of the entire table tennis ball serving device more stable.

[0013] To accommodate connection with a table tennis table, this utility model includes a suspension locking mechanism on the ball storage base. The suspension locking mechanism comprises a rectangular support frame. A shaft hole is formed on the upper crossbeam of the support frame. A bearing is installed on the inner side of the support frame corresponding to the shaft hole. An adjusting bolt is mounted on the support frame via the bearing, and its upper end extends out of the support frame and connects to an adjusting handle outside the support frame. A fine-tuning hook is provided inside the support frame, and the fine-tuning hook has a threaded hole. The fine-tuning hook is connected to the adjusting bolt via a thread. The lower end of the adjusting bolt is connected to the support frame via a bearing. The bottom of the frame is connected. When the adjustment handle is turned clockwise or counterclockwise, it drives the adjustment bolt to rotate. The fine-tuning hook moves linearly back and forth with the adjustment bolt. In use, the upper surface of the fine-tuning hook abuts against the lower surface of the table. A suspension bracket is also provided, hinged to the upper crossbeam of the support frame. The suspension bracket includes an L-shaped support arm, the upper end of which is hinged to the upper crossbeam via a pivot. The upper end of the vertical section of the L-shaped bracket has a pressure rod that presses against the upper surface of the table, and the end of the horizontal section of the L-shaped bracket has a vertically positioned abutment rod for abutting against the lower surface of the table. Each end of the suspension locking mechanism has a mounting seat with a round hole. An aluminum tube passes through the two abutment rods and is installed in the round hole. The mounting seat is fixed to the ball storage base, making the suspension locking mechanism and the ball dispensing base a single unit.

[0014] The upper surface of the fine-tuning hook 17 described in this example is a slope, which is used to lock the table tennis table of different sizes. Furthermore, the upper surface of the fine-tuning hook and the lower surface of the pressure bar are provided with an elastic rubber layer to improve the contact friction with the table tennis table.

[0015] The upper end of the abutment rod of this utility model is provided with a suction cup for increasing the contact area with the bottom surface of the table. Furthermore, in order to improve the support stability of the suspension locking mechanism, the suspension bracket is provided with at least two L-shaped support arms side by side, and corresponding pressure rods and abutment rods are provided.

[0016] In operation, this invention utilizes a ping-pong ball conveying device to continuously feed a large number of ping-pong balls from the ball storage base into the main ball lane. During the feeding process, if any deformed or damaged ping-pong balls are found, the ball feeding / returning assembly can be used to switch to the return ball lane in a timely manner, removing the damaged balls from the entire ball supply system and ensuring the continuous stability of the serving equipment from the source. In addition, this invention provides stable suspension support. Using a suspension locking mechanism, the entire ball storage base can be hung on the edge of the table. During this process, the fine-adjustment hook of the suspension locking mechanism abuts against the bottom surface of the table, the pressure rod presses against the upper surface of the table, and the upper end of the abutment rod abuts against the bottom surface of the table. The abutment rod and the pressure rod utilize the lever principle of the L-shaped support arm for a secure lock, avoiding problems such as unstable hooking, misalignment, and vibration that can cause serving failures in existing equipment.
