In addition, the terms "upper," "lower," "left," and "right" used in this utility model are only used with respect to the relative positions of the components of the utility model in the accompanying drawings.

[0049] Reference Figures 1 to 7A hinge support device 1 includes a first support member 11, a second support member 12, a plurality of spring members 13, and a safety lock assembly 14; a first end A1 of the first support member 11 and a first end B1 of the second support member 12 are rotatably connected (e.g., hinged); one end of the plurality of spring members 13 is connected to the first support member 11, and the other end is connected to the second support member 12; a second end A2 of the first support member 11 can be (directly or indirectly) disposed under the table tennis table 3; a second end B2 of the second support member 12 can be (directly or indirectly) connected to a table leg E2 of a table leg device 2;

[0050] The safety lock assembly 14 includes a first lock member 141 and a second lock member 142 ; if the first lock member 141 is fixed to the first end A1 of the first support member 11 , the second lock member 142 is rotatably disposed at the first end B1 of the second support member 12 ;

[0051] If the first locking member 141 is fixed to the first end B1 of the second supporting member 12 , the second locking member 142 is rotatably provided at the first end A1 of the first supporting member 11 ;

[0052] The second locking member 142 can cooperate with the first locking member 141 after being rotated and adjusted, and is used for safe locking of the first supporting member 11 and the second supporting member 12 after they are unfolded.

[0053] Reference Figures 1 to 7 In one embodiment, the second end A2 of the first support member 11 is indirectly disposed under the table 3 of the table tennis table, such as: through the connecting seat 25 described below, the second end A2 of the first support member 11 is indirectly connected to the underside of the table tennis table 3.

[0054] Reference Figures 1 to 7 In one embodiment, the second end B2 of the second support member 12 is indirectly connected to the leg E2 of the leg device 2, such as through the crossbeam 23 described below.

[0055] Reference Figures 1 to 7 In one embodiment, the first end A1 of the first support member 11 is hinged to the first end B1 of the second support member 12 through a rivet 15 .

[0056] Reference Figures 1 to 7 In one embodiment, the first support member 11 is provided with a first hook portion 111 at a set position, and the second support member 12 is provided with a second hook portion 121 at a set position; one end of the spring member 13 is connected to the first hook portion 111, and the other end is connected to the second hook portion 121.

[0057] In one embodiment, according to actual needs, the number of the spring members 13 connecting the first support member and the second support member can be one, two, three or four.

[0058] Reference Figures 1 to 7 In one embodiment, the first support member 11 and the second support member 12 are "U"-shaped components of a set length, and the first support member 11 and the second support member 12 respectively have a "U"-shaped groove 16; the first hook portion 111 is arranged in the "U"-shaped groove 16 of the first support member 11, and the second hook portion 121 is arranged in the "U"-shaped groove 16 of the second support member 12. Therefore, after the spring member 13 is connected, it can be in the space of the "U"-shaped groove 16. When the first support member 11 and the second support member 12 are folded and retracted, this design can hide the spring member 13 therein. At the same time, it is also beneficial for the spring member 13 to pull the first support member 11 and the second support member 12 together.

[0059] Reference Figures 1 to 7 In one embodiment, after the first support member 11 and the second support member 12 are fully extended, the spring member 13 is stretched due to the extension of the first support member 11 and the second support member 12. This design helps the spring member 13 tighten and straighten the fully extended first support member 11 and the second support member 12. Therefore, the first support member 11 and the second support member 12 can provide effective support for the table legs E2, solving the problem of the table tennis table shaking from side to side due to insufficient support force from the table legs. In this fully extended state, the first support member 11 and the second support member 12 need to be locked in position in conjunction with the safety lock assembly 14 to improve the support security of the first support member 11 and the second support member 12 in this state and prevent the "fully extended first support member 11 and the second support member 12" from being pulled back due to out-of-plane forces.

[0060] Reference Figures 1 to 7 In one embodiment, the first locking member 141 is a small "U"-shaped member; the second locking member 142 includes a connecting plate D1 and a dial plate D2; the dial plate D2 is provided on the connecting plate D1;

[0061] If the “U”-shaped member is fixed to the first end A1 of the first support member 11 , the connecting plate D1 is rotatably provided on the first end B1 of the second support member 12 ;

[0062] If the “U”-shaped member is fixed to the first end B1 of the second support member 12 , the connecting plate D1 is rotatably provided on the first end A1 of the first support member 11 ;

[0063] The dial plate D2 is used to adjust the position of the connecting plate D1 ; after the connecting plate D1 is rotated and adjusted, it can cooperate with (eg, snap fit) the first locking member 141 .

[0064] Reference Figures 1 to 7 In one embodiment, when the table leg E2 is retracted and the first support member 11 and the second support member 12 are fully folded back together, the spring member 13 can be in a naturally extended state or a slightly stretched state. This design prevents the table leg E2 of the foldable table tennis table 3 from suddenly opening. This design ensures that the normal opening of the table leg E2 requires work to overcome the elastic force of the spring member 13. Due to the presence of the spring member 13, the table leg E2 is unlikely to suddenly open, thereby preventing injuries to nearby personnel or damage to surrounding objects caused by the sudden opening of the table leg E2.
