[0039] Refer to the following Figures 1 to 6 The technical solutions of some embodiments of the utility model are described.

[0040] See attached Figure 1 and attached Figure 2 As shown, the utility model provides a telescopic table frame, comprising:

[0041] Two table leg assemblies 100;

[0042] At least one crossbeam assembly 200 is connected between two table leg assemblies 100. The crossbeam assembly 200 includes a first crossbeam 210 and a second crossbeam 220 which are socketed with each other and can be relatively telescopic. Both ends of the first crossbeam 210 are provided with first flanges 211 extending in the same direction. Both ends of the second crossbeam 220 are provided with second flanges 221 extending in the same direction. The first flange 211 and the second flange 221 extend in the same direction and abut against each other.

[0043] Specifically, the table leg assembly 100 includes an inner column tube and an outer column tube. The inner column tube is sleeved in the outer column tube, so that the table leg assembly 100 can be raised and lowered.

[0044] See attached Figure 2 As shown, specifically, both ends of the first beam 210 extend toward the direction close to the user to form a first flange 211, so that the first beam 210 forms a U-shaped groove structure, and both ends of the second beam 220 extend toward the direction close to the user to form a second flange 221, so that the second beam 220 forms a U-shaped groove structure, and the first flange 211 and the second flange 221 abut against each other so that the first beam 210 and the second beam 220 are mutually connected and can be relatively telescopic.

[0045] Specifically, the first crossbeam 210 and the second crossbeam 220 are socketed with each other and can be relatively retracted to achieve the purpose of relative retractability of the table frame. The first flange 211 and the second flange 221 extend in the same direction and abut against each other. When the connection between the first crossbeam 210 and the second crossbeam 220 is load-bearing, the first flange 211 and the second flange 221 can share the force applied to the connection between the first crossbeam 210 and the second crossbeam 220, thereby avoiding excessive force applied to the connection between the first crossbeam 210 and the second crossbeam 220, thereby improving the stability of the crossbeams.

During installation, the first mounting portion 212 and the second mounting portion 222 are aligned and connected with each other. The second crossbeam 220 is provided with a plurality of second mounting portions 222, and the first mounting portion 212 can be connected with different second mounting portions 222, and the overall length of the crossbeam assembly 200 will change accordingly, thereby achieving the effect that the table frame can be extended and retracted.

[0048] See attached Figure 4 and attached Figure 5 As shown, in an optional embodiment, the first mounting portion 212 includes two first through holes 212a, the second mounting portion 222 includes two second through holes 222a, and the distance between the two first through holes 212a matches the distance between the two second through holes 222a.

During installation, the first mounting portion 212 and the second mounting portion 222 fit each other, and the two first through-holes 212a can be aligned with the two second through-holes 222a respectively, and then connected, so that the first mounting portion 212 and the second mounting portion 222 have multiple force points when bearing weight, which can improve the stability of the connection between the first beam 210 and the second beam 220. In addition, the spacing between the two first through-holes 212a of the first mounting portion 212 is the same as the spacing between the two second through-holes 222a of the second mounting portion 222, so that the first mounting portion 212 and the second mounting portion 222 can be connected to each other in a coordinated manner.

[0050] In an optional embodiment, the first mounting portion 212 and the second mounting portion 222 are connected by bolt fasteners.

In addition, the bolt structure connection has a good load-bearing capacity, and the connection by bolt fasteners can make the first beam 210 and the second beam 220 more firmly connected, thereby achieving the purpose of improving the stability of the beam assembly 200.

[0052] See attached Figure 2 and attached Figure 3 As shown, in an optional embodiment, the first flange 211 includes a first upper flange 211a and a first lower flange 211b, the second flange 221 includes a second upper flange 221a and a second lower flange 221b, the first upper flange 211a is provided with a first convex hole 213, and / or the second upper flange 221a is provided with a second convex hole 223.

[0053] Specifically, after the first crossbeam 210 is connected to the second crossbeam 220, the first crossbeam 210 is located below the second crossbeam 220, resulting in a certain height difference between the first crossbeam 210 and the second crossbeam 220, and the first upper flange 211a of the first crossbeam 210 and the second upper flange 221a of the second crossbeam 220 are both at one end contacting the table top. After installation, the upper end surfaces of the first convex hole 213 and the second convex hole 223 are on the same horizontal plane. Therefore, providing convex holes on the first upper flange 211a and the second upper flange 221a can make the end of the telescopic table frame contacting the table top be on the same horizontal plane, so that when the table top is connected to the table frame, the table top can be in a horizontal state.

The support part 300 is in direct contact with the table top, and the upper end surface of the support part 300 is on the same horizontal plane, making the installation of the table top more stable.

[0059] See attached Figure 1 and attached Figure 6 As shown, in an optional embodiment, the support portion 300 includes a first support plate 310 and a second support plate 320, the first support plate 310 extends in the direction of the beam assembly 200, and the second support plate 320 extends in the height direction of the table leg assembly 100, and the first support plate 310 is connected to the beam assembly 200 by fasteners.

[0060] Specifically, the first support plate 310 extends in the length direction of the beam assembly 200, and the second support plate 320 extends in the height direction of the leg assembly 100. The first support plate 310 and the second support plate 320 are arranged perpendicular to each other.
