[0042] When the telescopic assembly 500 is installed on the cross beam 210 (at this time, one end of the hinge assembly 400 is fixed on one of the two support beams 300, and the other end of the hinge assembly 400 is in a disengaged state with the other of the two support beams 300; or, the hinge assembly 400 is not installed on the cross beam 210, and both ends of the hinge assembly 400 are in a disengaged state with the two support beams 300), one end of the telescopic assembly 500 is fixed on one of the support beams 300, and the other end of the telescopic assembly 500 is slidingly connected to the other support beam 300, so that the cross beam 210 can be telescopic; or, both ends of the telescopic assembly 500 are slidingly connected to the two support beams 300 respectively, so that the cross beam 210 can be telescopic.

[0043] The utility model discloses a table frame 200, which comprises a table board 100, a horizontal beam 210, two support beams 300 and a hinge assembly 400, wherein the horizontal beam 210 is arranged on the bottom of the table board 100, the two support beams 300 are arranged on the horizontal beam 210, and the hinge assembly 400 is arranged on the horizontal beam 210.

[0044] As shown in Figure 3 and Figure 4 In the embodiment, the installation position of the hinge assembly 400 is on the top surface of the horizontal beam 210, that is, when the hinge assembly 400 is installed on the horizontal beam 210, the two ends of the hinge assembly 400 are connected to the top of the two connecting ends 310, so that the horizontal beam 210 in the unfolded state can only rotate upward around the hinge assembly 400 to switch to the folded state, and the two support beams 300 rotate upward to fold the horizontal beam 210, so that the table leg 220 extending to the bottom of the two support beams 300 will not hinder the folding of the horizontal beam 210, and the folding of the horizontal beam 210 can be performed without disassembling the table leg 220 from the horizontal beam 210, thereby reducing the folding difficulty of the horizontal beam 210.

[0045] As shown in Figure 5 and Figure 6As shown, in this embodiment, a first locking member 610 and a second locking member 620 are respectively provided at the bottom of the two connecting ends 310. After the user unfolds the crossbeam 210, the first locking member 610 and the second locking member 620 can be locked to limit the two support beams 300, so that the crossbeam 210 is kept in the unfolded state with the two support beams 300 coaxial. During the process of locking the crossbeam 210 to the tabletop 100, the locked first locking member 610 and the second locking member 620 can effectively prevent the crossbeam 210 from folding freely, reduce the assembly difficulty of the crossbeam 210 and the tabletop 100, and improve the user's assembly experience. In this embodiment, the first locking member 610 and the second locking member 620 can have various structures, such as a horizontally inserted locking screw 521 and locking nut structure, or a horizontally inserted pin and socket structure, etc. Preferably, such as Figure 2 As shown, the first locking member 610 includes a fixing block 611 and a retaining ring 612. The fixing block 611 is fixed on one of the support beams 300, and one end of the retaining ring 612 is rotatably connected to the fixing block 611. The second locking member 620 is a hook 621 fixed on another support beam 300. The retaining ring 612 can be rotated to engage or disengage with the hook 621. When the hook 621 is engaged in the retaining ring 612, the first locking member 610 and the second locking member 620 are locked together. The structure is simple, easy for users to operate, and reduces the time required to lock the first locking member 610 and the second locking member 620.

[0046] In this embodiment, a receiving groove 311 is provided at the bottom of both connecting ends 310. The two receiving grooves 311 have a bottom opening facing the bottom and a side opening arranged opposite to each other. The first locking member 610 and the second locking member 620 are respectively provided in the receiving grooves 311 of the two connecting ends 310. The retaining ring 612 can be inserted into the adjacent receiving groove 311 through the side opening arranged opposite to each other to lock with the hook 621. The first locking member 610 and the second locking member 620 are set in the receiving grooves 311, which is more aesthetically pleasing and can also effectively prevent the first locking member 610 and the second locking member 620 from affecting the installation of the telescopic component 500.

[0047] In this embodiment, the hinge assembly 400 is a hinge 410, such as... Figure 4 As shown, the hinge 410 includes a first leaf 411, a second leaf 412, and a rotating member 413. The first leaf 411 and the second leaf 412 are rotatably connected to both sides of the rotating member 413. The first leaf 411 and the second leaf 412 are respectively used to connect two support beams 300. With a simple structure, the rotation of the two support beams 300 can be realized, reducing the space occupied by the hinge assembly 400, avoiding the hinge assembly 400 from affecting the rotation of the support beams 300, and reducing costs.

[0048] like Figure 7 and Figure 8As shown, in this preferred embodiment, the telescopic component 500 is detachably connected to two support beams 300 at both ends. The telescopic component 500 in this embodiment includes a sliding member 520 and a connecting member 510. Sliding holes 511 are provided at both ends of the connecting member 510, extending horizontally. The connecting member 510 covers the connecting ends 310 of the two support beams 300. The sliding member 520 is fixed to the side of the connecting end 310 and horizontally passes through the sliding hole 511 for sliding connection with the sliding hole 511. By inserting the connecting member 510 into the sliding hole 511, a sliding connection between the connecting member 510 and the support beam 300 can be achieved. The structure is simple, easy to assemble and disassemble, convenient to use, and improves the user experience. Preferably, the sliding member 520 is a locking screw 521, which passes through and is slidably fixed to the support beam 300. The head of the locking screw 521 is located on the side of the sliding member 520 away from the support beam 300. When the locking screw 521 is not locked to the support beam 300, the gap between the head of the locking screw 521 and the support beam 300 is wider than the width of the connector 510, so that the locking screw 521 can slide horizontally in the sliding hole 511 to adjust the length of the crossbeam 210. After the length of the crossbeam 210 is adjusted, the locking screw 521 is tightened so that the head of the locking screw 521 and the side wall of the support beam 300 clamp the connector 510 together, and the crossbeam 210 is kept in the required extension and retraction position, preventing the length of the crossbeam 210 after adjustment from changing freely, which is convenient for operation.

[0049] The connector 510 has multiple (two or more) sliding holes 511 at both ends, such as... Figure 8 As shown, multiple sliding holes 511 are spaced apart along the same horizontal line. The spaced sliding holes 511 allow the crossbeam 210 to have a larger adjustment range, while also preventing the strength of the connector 510 from being too low due to the excessive length of a single sliding hole 511, thus preventing deformation of the connector 510 and extending the service life of the connector 510.

[0050] In this embodiment, a single hinge assembly 400 may be provided to simplify the overall installation steps of the crossbeam 210. This embodiment uses a single hinge assembly 400 as an example for illustration. Of course, it is understood that in other embodiments, to enhance the strength at the hinge joint of the two support beams 300, multiple hinge assemblies 400 (two or more) may be provided, such as... Figure 9 As shown, two hinge assemblies 400 are arranged side by side and are connected to two support beams 300 respectively.
