Referring to fig. 2, the table frame 100 includes a left leg frame 110, a right leg frame 120, and two frame cross members 130 disposed between the left leg frame 110 and the right leg frame 120 at intervals for connecting and fixing the left leg frame 110 and the right leg frame 120. Of course, the number of the cross members 130 of the table frame should be set according to the coupling strength of the table frame 100.

In this embodiment, the table frame beam 130 adopts a telescopic table frame beam with a uniform specification, so that the table frame 100 can adjust a suitable length according to the table boards 200 with different lengths, and the telescopic table frame beam shown in fig. 3, 6 and 7 is in a state when being telescopic into different lengths, so that the table frame beam can be uniformly packaged, the types of materials are reduced, the material management is convenient, the transportation volume is reduced, and the transportation cost is reduced.

In particular, referring to fig. 3 to 8, the telescopic table frame rail includes a left rail sleeve 131, a right rail sleeve 132, and a middle rail tube 133. The left and right beam sleeves 131, 132 are slidably fitted over outer peripheral surfaces of left and right portions of the middle beam tube 133. The left beam sleeve 131 and the right beam sleeve 132 are rectangular in longitudinal section and are symmetrically arranged. The longitudinal cross section of the middle cross beam tube 133 is substantially similar to the longitudinal cross sections of the left and right cross beam tubes 131, 132, but slightly smaller than the dimensions of the left and right cross beam tubes 131, 132. When the left and right beam sleeves 131, 132 are slid along the middle beam tube 133 to a desired overall length, the left and right beam sleeves 131, 132 are secured to the middle beam tube 133 by left and right fasteners.

Two left fastening screw holes 131a are axially arranged on the bottom surface of the left beam sleeve 131 at intervals, the left fastening screw holes 131a are positioned near the right end of the left beam sleeve 131, and the number of the left fastening screw holes can be set according to fastening requirements, and at least one left fastening screw hole can be arranged; two right fastening screw holes 132a are axially spaced on the bottom surface of the right beam sleeve 132, and the right fastening screw holes 132a are located near the left end of the right beam sleeve 132, and the number of the right fastening screw holes can be set according to fastening requirements, and at least one right fastening screw hole can be set. When the left and right fixing screw holes 131a and 132a are fixed, the fixing screws 134 are respectively and correspondingly screwed into the left and right fixing screw holes, so that the front end of each fixing screw 134 is abutted against the bottom surface of the middle beam tube 133 in an extrusion manner, and the left and right beam sleeves 131 and 132 are connected and fixed with the middle beam tube 133.

Further, a tightening groove 133a extending in the axial direction is formed on the bottom surface of the intermediate beam tube 133, and the front end portion of each tightening screw 134 abuts in the tightening groove 133a of the intermediate beam tube 133.

Further, the longitudinal section of the fastening groove 133a is isosceles trapezoid, the top surface 134a of the front end portion of each fastening screw 134 is plane, and the extrusion conical surface 134b is formed at the periphery thereof; when the set screw 134 is locked, the extrusion conical surface 134b formed at the periphery of the front end of the set screw 134 extrudes and presses the trapezoid waist edges on both sides of the fixed groove 133a, so that the fixed groove 133a of the middle beam tube 133 deforms and extrudes to both lateral sides and moves slightly to both lateral sides; at the same time, the top surface 134a of the front end portion of the set screw 134 presses against the trapezoidal top surface of the set groove 133a, so that the middle cross beam tube 133 moves upward, and the middle cross beam tube 133 is fixedly connected with the left and right cross beam bushings 131, 132 by the lateral and longitudinal pressing forces. The tighter the set screw 134 is locked, the greater the lateral and longitudinal compressive forces applied to the middle cross beam tube 133, and the more secure the connection between the middle cross beam tube 133 and the left and right cross beam tubes 131, 132.

The middle beam tube 133 is formed with reinforcing relief grooves 133b extending in the axial direction on two lateral sides thereof, and since the outer sides of the left beam sleeve 131 and the right beam sleeve 132 are required to be provided with a plurality of supporting locking members 135 for locking the table, the connecting screws on the supporting locking members 135 are retracted into the reinforcing relief grooves 133b on two lateral sides of the middle beam tube 133, and the reinforcing relief grooves 133b play a role of relief. Meanwhile, the reinforcement yielding groove 133b plays a certain role in reinforcing the middle beam tube 133, and the structural strength of the middle beam tube 133 is improved.

Graduations (not shown) are provided on the outer surface of the middle beam 133 to facilitate the adjustment of the left and right beam bushings 131, 132 by an installer.
