[0002] The ping-pong table is an essential piece of equipment in the sport of table tennis. It provides a standardized playing area for ping-pong matches and training. Its size, material, and elasticity meet the requirements of the sport, ensuring fairness and competitiveness. The net divides the ping-pong table into two equal playing areas, clearly defining the positions and hitting ranges of both players, which is the foundation for the normal conduct of a ping-pong match.

[0003] A search revealed Chinese Patent Publication No. CN220309709U, which discloses a ping-pong table with an easy-to-assemble net frame. By pulling down the mounting hooks at both ends of the net frame, aligning the opening of one end of the mounting hook with the scraper, and then aligning the insert at the bottom of the net frame with the socket on the ping-pong table, the mounting hooks are released. Under the action of the tightening mechanism, the mounting hooks move upward, thus fixing the mounting hooks with the scraper. Consequently, the insert also aligns with the socket. Finally, the net frame can be conveniently installed on the ping-pong table in the above manner.

[0004] In the above technical solution, the net frame can be installed through the mounting hooks, scrapers and inserts at both ends. However, the net frame is fixed in the center of the table, and the net cannot adjust the area of ​​the two areas on the table. As a result, athletes can only train in the conventional fixed area during daily training, which makes it difficult to fully develop and improve comprehensive technical abilities, such as the balanced development of close-to-the-table, mid-table and far-table techniques. This reduces the practicality and flexibility of the table tennis table. Therefore, a table tennis table that is easy to assemble with a net frame is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ping-pong table that is easy to assemble with a net frame. It aims to improve the problem in the prior art where it is difficult to adjust the two areas on the tabletop when installing the net frame, which leads to repeated practice of similar hitting distances and angles during training, reducing the training effect and decreasing the practicality and flexibility of the ping-pong table.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ping-pong table that facilitates the assembly of a net frame, comprising a table body, a net body being provided on the top of the table body, a movable groove being provided on the side wall of the table body, a fixed frame being slidably connected to the inner wall of the movable groove, a positioning hole being provided on the inner wall of the table body, a slot being provided on the outer wall of the fixed frame, a spring being fixedly connected to the inner wall of the slot, a pull block being fixedly connected to the end of the spring, a positioning rod being fixedly connected to the side wall of the pull block, a T-shaped groove being provided on the top of the fixed frame, a fixed cylinder being provided inside the T-shaped groove, a bidirectional lead screw being rotatably connected to the inner wall of the fixed cylinder, a dial ring being fixedly connected to the center of the bidirectional lead screw, a movable plate being threadedly connected to the outer wall of the bidirectional lead screw, and an insert rod being fixedly connected to the side wall of the movable plate.

[0007] As a further description of the above technical solution:

[0008] The inner wall of the positioning hole is adapted to the outer wall of the positioning rod, and the positioning rod passes through the fixing frame.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the pull block is adapted to the inner wall of the slot, and the inner wall of the T-slot is adapted to the outer wall of one side of the fixed cylinder.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the movable plate is slidably connected to the inner wall of the fixed cylinder, and the dial ring is protruding on the upper surface of the fixed cylinder.

[0013] As a further description of the above technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a ping-pong table that facilitates the assembly of a net frame. The table includes a table body 1, a net body 2 on the top of the table body 1, and two sets of movable grooves 4 on the side walls of the table body 1. These two sets of movable grooves 4 are mirror images of each other about the central axis of the table body 1 and are located on the right side of the table body 1. A fixing frame 3 is slidably connected to the inner wall of the movable grooves 4. Several sets of positioning holes 5 are equidistantly distributed within the two sets of movable grooves 4 on the inner wall of the table body 1. A slot 6 is formed on the outer wall of the fixing frame 3, and a spring 9 is fixedly connected to the inner wall of the slot 6. A pull block 7 is fixedly connected to the end of the spring 9, and a positioning rod 8 is fixedly connected to the side wall of the pull block 7. A T-slot 10 is formed on the top of the fixing frame 3. The T-slot 10 has a fixed cylinder 11 inside. There are two sets of fixed brackets 3 and fixed cylinders 11, which are mirror images of each other with the central axis of the table body 1 as the axis of symmetry. The inner wall of the fixed cylinder 11 is rotatably connected to a two-way screw 13. A dial ring 12 is fixedly connected to the center of the two-way screw 13. The outer wall of the two-way screw 13 is threadedly connected to a moving plate 14. Each set of fixed cylinders 11 has two sets of moving plates 14 inside. On the opposite side of the two sets of moving plates 14, there are multiple sets of equally spaced insertion rods 15. The side wall of the moving plate 14 is fixedly connected to the insertion rods 15. The multiple sets of insertion rods 15 are distributed alternately in pairs on the two sets of moving plates 14. The surface of the fixed cylinder 11 has through holes for the insertion rods 15 to pass through. The insertion rods 15 can pass through the holes of the net body 2 to fix the net body 2.

[0033] Reference Figures 3-5 The inner wall of the positioning hole 5 is adapted to the outer wall of the positioning rod 8. The positioning rod 8 passes through the fixing frame 3. The outer wall of the pull block 7 is adapted to the inner wall of the slot 6. The inner wall of the T-slot 10 is adapted to one side of the outer wall of the fixing cylinder 11. The outer wall of the moving plate 14 is slidably connected to the inner wall of the fixing cylinder 11. The moving plate 14 slides inside the fixing cylinder 11, which can limit the movement of the moving plate 14, so that it can only move horizontally by the drive of the bidirectional screw 13. The dial ring 12 is raised on the upper surface of the fixing cylinder 11. The dial ring 12 is raised on the fixing cylinder 11, which makes it convenient for the hand to contact and drive it to rotate.

[0034] Reference Figure 3The pull block 7 has an embedded groove 16 on its side wall. The embedded groove 16 is located on the outer wall of the pull block 7 away from the positioning rod 8. There are two sets of embedded grooves 16. The inner wall of the embedded groove 16 is fixedly connected with anti-slip protrusions 17. The anti-slip protrusions 17 are located on the side of the two sets of embedded grooves 16 that are close to each other. This can increase the friction between the embedded grooves 16 and prevent the risk of the pull block 7 from dislodging when the hand applies force to it. The inner wall of the slot 6 is fixedly connected with a magnetic ring 18. The side wall of the magnetic ring 18 is magnetically connected with a magnetic ring 2 19. The magnetic ring 18 is sleeved on the outer wall of the spring 9. The side wall of the magnetic ring 2 19 is fixedly connected to the side of the pull block 7 that is close to the spring 9. After the spring 9 is stretched, the magnetic attraction between the magnetic ring 18 and the magnetic ring 2 19 can help it to rebound quickly.

[0035] Working principle: When assembling the net body 2, vertically insert one end of the net body 2 into the opening of the fixing cylinder 11. Manually move the dial ring 12 in the forward direction. The dial ring 12 controls the rotation of the bidirectional screw 13, causing the two pairs of moving plates 14 to move closer to each other, thus allowing the two pairs of staggered insert rods 15 to move out of the fixing cylinder 11 until multiple sets of insert rods 15 pass through both sides of the net body 2. Then, align the fixing cylinder 11 with the T-slot 10 and insert it to connect it with the fixing frame 3. Repeat the above steps on the other end of the net body 2 to complete the fixing of the net body 2. Manually pull the pull block 7 outward. The pull block 7 drives the spring 9 to stretch, causing the positioning rod 8 to move out of the positioning hole 5. Then, apply force to the fixing frame 3 to make... The net 2 moves within the moving slot 4. When the net 2 moves to the appropriate position, the positioning rod 8 is aligned with the corresponding positioning hole 5. The elasticity of the spring 9 and the magnetic attraction of the magnetic ring 18 and magnetic ring 19 allow the positioning rod 8 to quickly insert into the corresponding positioning hole 5, thereby fixing the frame 3. By adjusting the position of the net 2, the two areas of the table 1 have different sizes, providing athletes with more tactical options. For example, on the smaller side, athletes can focus more on close-to-the-table fast attack or short ball control training, while on the larger side, they can practice mid-to-long-range rallies, powerful shots, and other techniques, improving the practicality and flexibility of the table tennis table.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
