[0015] A further technical solution is that the retractable ping-pong table also includes an elastic pad, which is detachably disposed on the upper end of the rectangular tabletop, and the shape of the elastic pad is the same as that of the rectangular tabletop.

[0016] A further technical solution is that the four corners of the rectangular tabletop are rounded.

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

[0018] (I) A retractable ping-pong table includes an assembled keel, a rectangular tabletop, and a detachable net. The rectangular tabletop is detachably mounted on the upper end of the assembled keel. During disassembly, the rectangular tabletop is first removed from the assembled keel. The rectangular tabletop includes several rotating plates, which are connected end to end along the length of the assembled keel. Adjacent rotating plates are rotatably connected. Each rotating plate is rotated upwards or downwards and folded up. Support frames are rotatably mounted at the four corners of the lower end of the assembled keel. The support frames are rotated inwards and folded up against the assembled keel. The entire ping-pong table is divided into multiple independent units, each of which is smaller in size. Users can arrange the folded rectangular tabletop and the assembled keel in sequence, making full use of various fragmented spaces to flexibly arrange and store the independent units, reducing the weight of each transport, making storage and movement easier and less labor-intensive, and improving the convenience of storing and arranging the ping-pong table.

[0019] (II) Furthermore, the retractable ping-pong table also includes several diagonal braces. The lower ends of the diagonal braces are rotatably connected to the side of the middle section of the support frame, and the upper ends of the diagonal braces are detachably connected to the lower end of the assembled keel. Four support frames rotate outwards, and the diagonal braces rotate outwards, with their upper ends connected to the lower end of the assembled keel, fixing the four support frames. The lower ends of the four support frames contact the ground and support and fix the assembled keel. For example, each support frame includes two support legs. The upper ends of the two support legs are coaxially arranged at the lower end of the assembled keel, and the lower ends of the diagonal braces are rotatably connected to the side of the middle section of the support legs. The two support legs of one support frame rotate to the left and right sides respectively, and two corresponding diagonal braces rotate to the left and right sides respectively, with their upper ends connected to the lower end of the assembled keel, fixing the two support legs. Each support frame has two independent support legs that rotate and unfold to the left and right sides respectively, increasing the span of contact with the ground and improving the anti-tilting ability. At the same time, the lower end of the diagonal brace is rotatably connected to the middle side of the support leg, and the upper end is detachably fixed to the lower end of the keel. When the diagonal brace rotates outward synchronously with the support leg and locks, a rigid triangular truss structure is formed between the support leg and the keel. The diagonal brace applies lateral constraint force to the support leg, locking and stabilizing the two support legs.

[0020] (III) Furthermore, the foldable ping-pong table also includes an elastic pad, which is detachably mounted on the top of the rectangular tabletop. The shape of the elastic pad is the same as that of the rectangular tabletop. This elastic pad, through its detachable design, covers the surface of the rectangular tabletop, concealing the recessed gaps at the rotating joints of the rotating plate structure. This prevents the ping-pong ball from changing its rebound path when it contacts the recessed gaps when the user hits the ball directly on the rectangular tabletop. Moreover, the elastic pad can be rolled up into a thin layer for independent storage, improving the convenience of storage. Attached Figure Description

[0028] Example:

[0029] A retractable ping-pong table includes an assembled frame 100, a rectangular tabletop 200, and a detachable net 300.

[0030] Figure 1 This is an isometric drawing of a retractable ping-pong table according to the present invention. Figure 2 This is a front view structural diagram of a retractable ping-pong table according to the present invention. Figures 1-2 As shown, the lower four corners of the assembled keel 100 are rotatably equipped with support frames, the lower ends of which contact the ground and support the assembled keel 100. For example, the assembled keel 100 is a modular structure, comprising two horizontal bars and two vertical bars. The two vertical bars are arranged parallel to each other. The left and right ends of one horizontal bar are detachably connected to the front ends of the two vertical bars, and the left and right ends of the other horizontal bar are detachably connected to the rear ends of the two vertical bars, forming a detachable rectangular keel frame. Support frames are located on the left and right sides of the horizontal bars, and the cross-sectional area of ​​the keel frame is smaller than the cross-sectional area of ​​the rectangular tabletop 200.

[0031] Figure 3 This is a top view schematic diagram of the rectangular tabletop of a retractable ping-pong table according to this utility model. Figure 3 As shown, a rectangular tabletop 200 is detachably mounted on the upper end of the assembly keel 100. The rectangular tabletop 200 includes six rotating plates 201 connected end-to-end along the length of the assembly keel 100. Adjacent rotating plates 201 are rotatably connected. When the six rotating plates 201 are rotated to a horizontal position, they form the rectangular tabletop 200. For example, the four corners of the rectangular tabletop 200 are rounded.

[0032] like Figures 1-3 As shown, the front and rear sides of the detachable net 300 are detachably disposed at the center of the front and rear sides of the rectangular tabletop 200. For example, the front and rear sides of the detachable net 300 are connected to net frames, with two net frames detachably disposed at the center of the front and rear sides of the rectangular tabletop 200 respectively.

[0033] like Figures 1-2 As shown, the retractable ping-pong table further includes several diagonal braces 120. The lower ends of the diagonal braces 120 are rotatably connected to the side of the middle section of the support frame, and the upper ends of the diagonal braces 120 are detachably connected to the lower end of the assembled keel 100. Four support frames rotate outwards, and the diagonal braces 120 rotate outwards, with their upper ends connected to the lower end of the assembled keel 100, fixing the four support frames. The lower ends of the four support frames contact the ground and support and fix the assembled keel 100. For example, each support frame includes two support legs 110. The upper ends of the two support legs 110 are coaxially arranged at the lower end of the assembled keel 100, and the lower ends of the diagonal braces 120 are rotatably connected to the side of the middle section of the support legs 110. The two support legs 110 of one support frame rotate to the left and right sides respectively, and two corresponding diagonal braces 120 rotate to the left and right sides respectively, with their upper ends connected to the lower end of the assembled keel 100, fixing the two support legs 110. Each support frame has two independent support legs 110 that rotate and unfold to the left and right sides respectively, expanding the span of contact with the ground and improving the anti-tilting ability. At the same time, the lower end of the diagonal brace 120 is rotatably connected to the middle side of the support leg 110, and the upper end is detachably fixed to the lower end of the keel. When the diagonal brace 120 rotates outward synchronously with the support leg 110 and locks, a rigid triangular truss structure is formed between the support leg 110 and the keel. The diagonal brace 120 applies a lateral constraint force to the support leg 110, locking and stabilizing the two support legs 110.

[0034] like Figures 1-2 As shown, the support leg 110 is further designed to be telescopic, comprising a sleeve rod 111 and a telescopic rod 112. The upper end of the sleeve rod 111 is rotatably connected to the lower end of the assembled keel 100, and the telescopic rod 112 is slidably connected within the sleeve rod 111. The lower end of the diagonal brace 120 is rotatably connected to the side of the lower end of the sleeve rod 111. When the telescopic rod 112 is fully retracted into the sleeve rod 111, the volume of the support leg 110 is further reduced, thereby further compressing its storage volume and improving space utilization.

[0035] like Figures 1-2 As shown, the lower end of the telescopic rod 112 is further rotatably connected to a support plate 130. When the support plate 130 is unfolded, it rotates to a horizontal ground-hugging state, increasing the ground contact area and preventing the rigid support leg 110 from slipping or wearing out. At the same time, when stored, it stands upright parallel to the telescopic rod 112, achieving space-free folding and improving space utilization.

[0036] like Figures 1-2 As shown, the retractable ping-pong table further includes an elastic pad 400, which is detachably mounted on the upper end of the rectangular tabletop 200. The shape of the elastic pad 400 is the same as that of the rectangular tabletop 200. This elastic pad 400, through its detachable design, covers the surface of the rectangular tabletop 200, concealing the recessed gap at the rotating joint of the rotating plate 201 structure. This prevents the ping-pong ball from changing its rebound path when it contacts the recessed gap when the user hits the ball directly on the rectangular tabletop 200. Furthermore, the elastic pad 400 can be rolled into a thin layer for independent storage, improving storage convenience.

[0037] In operation, this embodiment is as follows:

[0038] When unfolding the collapsible ping-pong table, firstly, rotate the support frames at the four corners of the lower end of the assembled keel 100 outwards. Then, rotate the two support legs 110 of each support frame outwards to the working position. Next, pull out the telescopic rod 112 inside the sleeve rod 111 to the required height and lock it. At the same time, rotate the support plate 130 at the lower end of the telescopic rod 112 to make it flat against the ground. Then, rotate the diagonal brace 120 in the middle of the side of the rotating sleeve rod 111 outwards and connect and fix its upper end to the lower end of the assembled keel 100, thereby locking the support legs 110 to form a stable triangular support structure. After completing the keel support, rotate the multiple hinged rotating plates 201 one by one to a horizontal state to assemble a complete rectangular tabletop 200 and place and fix it on the upper end of the assembled keel 100. Finally, install the net frames on the front and rear sides of the detachable net 300 to the middle positions of the front and rear sides of the rectangular tabletop 200. Finally, lay a detachable elastic pad 400 with a matching shape on the rectangular tabletop 200. When storing, the operation is reversed. First, remove the net and net frame, and remove the elastic pad 400. Then, remove the rectangular table 200 from the keel. Rotate and fold each rotating plate 201 one by one upward or downward. Next, disconnect the upper end of the diagonal brace 120 from the assembled keel 100 and rotate the diagonal brace 120 inward to fold it. Then, retract the telescopic rod 112 of the support leg 110 into the sleeve rod 111, rotate and fold the support plate 130. Finally, rotate and fold the support leg 110 inward to fold it against the assembled keel 100 to complete the storage of the entire device.

[0039] In this embodiment, the entire ping-pong table is divided into multiple independent units, each of which is smaller in size. Users can arrange the folded rectangular tabletop 200 and the assembled keel 100 in sequence, making full use of various fragmented spaces to flexibly arrange and store the independent units, reducing the weight of each transport, making storage and movement easier and less strenuous, and improving the convenience of storing and arranging the ping-pong table.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
