Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a ping-pong table. Background Technology

[0002] Table tennis is a popular sport enjoyed by people of all ages. Whether in schools, community centers, or professional sports venues, people can be seen enjoying the fun of table tennis.

[0003] However, existing ping-pong tables have many shortcomings in practical use. Traditional ping-pong tables typically use fixed sizes and structural designs, resulting in a large overall volume, making them extremely difficult to place in spaces with limited indoor space, such as small school classrooms or family activity rooms. Furthermore, because traditional ping-pong tables are mostly one-piece structures, they are heavy and made of relatively rigid materials, making them difficult to disassemble and fold. Moving a ping-pong table from one place to another, such as from a school playground to an indoor gymnasium, or when a family wants to take the table for outdoor activities, often requires a significant amount of manpower, resources, and time. This inconvenient portability not only increases the cost of use but also reduces the flexibility of the ping-pong table, failing to meet people's needs for playing ping-pong anytime, anywhere. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the aforementioned problems with a ping-pong table, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a ping-pong table, comprising two table surfaces, which are hinged to each other by a hinge member, and when the two table surfaces are unfolded, their upper surfaces are on the same horizontal plane;

[0007] At least four support legs are rotatably mounted at the bottom of the two platforms near the corners;

[0008] At least four first rotary locking fasteners, one end of which is fixedly connected to the bottom of the tabletop and the other end of which is fixedly connected to the side wall of the corresponding support leg;

[0009] A spring-loaded plate, one end of which is hinged to the edge of the table surface, and a second rotating locking element is provided between the spring-loaded plate and the table surface;

[0010] When the ping-pong table is in the unfolded state, the first rotating lock fastener locks and limits the table surface and the support leg to be in a perpendicular state, and the second rotating lock fastener locks and limits the impact plate to be in a perpendicular state to the table surface. The table surface and the impact plate form a lateral "L" shaped structure.

[0011] In a preferred embodiment of the ping-pong table described in this utility model, the first rotating locking member and the second rotating locking member have the same structure, including:

[0012] Two connecting rods are rotatably connected at one end with a misalignment. The rotating ends of the two connecting rods are respectively provided with a locking groove and a locking protrusion. When the locking groove and the locking protrusion are engaged with each other, the two connecting rods are kept on the same straight line and are in a locked state.

[0013] In a preferred embodiment of the ping-pong table described in this utility model, when the two table surfaces are in the unfolded state, the hinge member forms a triangular support relative to the two table surfaces.

[0014] As a preferred embodiment of the ping-pong table described in this utility model, a vision recovery diagram is provided on one side of the table surface of the impact plate.

[0015] In a preferred embodiment of the ping-pong table described in this utility model, the rotation and retraction directions of the two table surfaces are opposite to the rotation and retraction direction of the striking plate.

[0016] In a preferred embodiment of the ping-pong table described in this utility model, a friction-enhancing pad is provided at the bottom end of the supporting leg.

[0017] The beneficial effects of this utility model are:

[0018] 1. The entire unit can be folded up by using a retractable spring plate, two relatively rotatable platforms, and retractable support legs at the bottom, reducing the footprint and making it easy to carry. Furthermore, when the platforms are unfolded, the combination of the first rotating locking fastener, the second rotating locking fastener, and the hinge can enhance the connection between the platforms, support legs, and spring plate, further improving the stability of use.

[0019] 2. By placing a vision recovery chart on one side of the table tennis paddle, users will unconsciously focus their gaze frequently on it during exercise. Due to the fast pace of table tennis, the ball's back-and-forth motion prompts rapid eye movement. During this process, users continuously focus on the vision recovery chart, their eyes adjusting for near and far distances, much like performing an "aerobic exercise" for the eyes. This not only effectively exercises the ciliary muscles of the eyes, enhancing their accommodative ability, but also relieves eye fatigue caused by prolonged close-range use of the eyes. This significantly contributes to preventing the progression of myopia and improving vision, providing users with the added benefit of protecting their eye health while enjoying the fun of table tennis.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0031] Reference Figures 1-5 This invention provides a ping-pong table, comprising two tabletops 1. The tabletops 1 are made of high-elasticity, high-density fiberboard, a material that imparts excellent elasticity and allows for precise feedback of the ball's force upon impact, resulting in a smooth and satisfying feel. The surface of the board is treated with advanced UV coating technology, resulting in a uniform and delicate finish that enhances the wear resistance of the tabletops 1 while also exhibiting a bright luster.

[0032] The two tabletops 1 are hinged together by a hinge 11. When the two tabletops 1 are unfolded, their upper surfaces are on the same horizontal plane, and the sides of the two tabletops 1 are attached to each other as a whole, which makes it convenient to hit the table tennis ball. In addition, when the two tabletops 1 are in the unfolded state, the hinge 11 forms a triangular support between the two tabletops 1, which further improves the stability of the two tabletops 1.

[0033] At least four support legs 2, with a reinforcing rod 21 fixed between two adjacent support legs 2 to enhance the connection strength of the support legs 2. The four support legs 2 are respectively rotatably set at the bottom of the two platform 1 near the corner. The bottom end of the support legs 2 is provided with a friction pad (made of rubber) to increase the friction with the ground, prevent large displacement during movement, and further improve the stability of movement.

[0034] At least four first rotating locking fasteners 3, one end of which is fixedly connected to the bottom of the tabletop 1 and the other end of which is fixedly connected to the side wall of the corresponding support leg 2;

[0035] The impact plate 4 is hinged at one end to the edge of the tabletop 1. A second rotating locking fastener 41 is provided between the impact plate 4 and the tabletop 1. A vision recovery chart 42 is provided on one side of the tabletop 1 on the impact plate 4. The vision recovery chart 42 adopts the international standard recovery chart and is composed of multiple concentric circles. It stimulates the retina and optic nerve through details and changes, improves the eye's ability to perceive different contrasts, brightness and spatial frequencies, thereby improving visual acuity and clarity, and helping to improve vision.

[0036] During the exercise, users will unconsciously and frequently focus their gaze on the vision recovery chart 42. Because of the fast pace of table tennis, the ball's back-and-forth motion prompts rapid eye movement. During this process, as users continuously focus on the vision recovery chart 42, their eyes adjust for near and far distances, much like performing an "aerobic exercise" for the eyes. This not only effectively exercises the ciliary muscles of the eyes, enhancing their accommodative ability, but also relieves eye fatigue caused by prolonged close-range use of the eyes. Therefore, it plays a significant role in preventing the progression of myopia and improving vision, providing users with the added practical benefit of protecting their eye health while enjoying the fun of table tennis.

[0037] The first rotary locking element 3 and the second rotary locking element 41 have the same structure, including:

[0038] like Figure 2 and Figure 3 As shown, two connecting rods 3a are rotatably connected at one end with offset. The rotating ends of the two connecting rods 3a are respectively provided with a locking groove and a locking protrusion. When the locking groove and the locking protrusion are engaged with each other, the two connecting rods 3a are limited to keep on the same straight line and are in a locked state.

[0039] like Figure 1 and Figure 2 As shown, when the ping-pong table is in the unfolded state, the first rotating locking fastener 3 locks and limits the table surface 1 and the support leg 2 to be in a perpendicular state, and the second rotating locking fastener 41 locks and limits the impact plate 4 and the table surface 1 to be in a perpendicular state, forming a lateral "L" shaped structure between the table surface 1 and the impact plate 4.

[0040] In its unfolded state, the ping-pong table can enhance the connection between the tabletop 1, the support leg 2, and the spring plate 4 through the coordinated use of the first rotating locking fastener 3, the second rotating locking fastener 41, and the hinge 11, thereby further improving its stability in use.

[0041] like Figure 4 and Figure 5 As shown, when the ping-pong table is in the stowed state, the rotation and retraction directions of the two table surfaces 1 are opposite to the rotation and retraction direction of the impact plate 4. The impact plate 4 is in contact with the corresponding table surface 1, the support leg 2 rotates to be parallel to the table surface 1, and the two table surfaces 1 rotate around the hinge 11 and retract into one.

[0042] When folded, the ping-pong table occupies less space and has a more compact structure, making it easier to move and store, thus increasing its flexibility and meeting people's needs to play ping-pong anytime, anywhere.

[0043] In addition, the height of the tabletop 1 is between 68 and 76 cm, making it suitable for placement in homes, kindergartens, and school sports fields, and convenient for young children and adults to use.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
