[0002] The load-bearing frame can be used in many occasions, such as warehousing, outdoor facilities, cold storage, etc. Most of the existing load-bearing frames are fixed structures. The horizontal frame and the column are usually fixed by screws. For the relevant structure, please refer to the Chinese patent publication number CN209300466U, entitled "A Load-Bearing Frame", which records:

[0003] "A load-bearing frame comprises an inverted Y-shaped base frame, a load-bearing frame body sleeved and fixed on the upper end of the base frame, and a height adjustment mechanism arranged between the base frame and the load-bearing frame body; the load-bearing frame body comprises a longitudinal rod sleeved on the upper end of the base frame, and a plurality of transverse rods transversely arranged on the inner side of the longitudinal rod; a plurality of height-adjusting holes are arranged on the inner side of the base frame, and the height-adjusting mechanism comprises an adjusting seat installed on the side of the longitudinal rod, an L-shaped adjusting pin installed in the adjusting seat and insertable into the adjusting hole, and a return spring arranged in the adjusting seat and playing a returning role for the adjusting pin. After the adjusting pin is pulled outward and the adjusting pin is disengaged from the adjusting hole, the relative position of the longitudinal rod and the base frame is adjusted to adjust the appropriate height and align the adjusting pin with the adjusted adjusting hole. After the adjusting pin is released, the return spring plays a returning role for the adjusting pin so that the adjusting pin automatically returns to the position and is inserted into the adjusting hole; a screw hole is arranged at the lower end of the longitudinal rod, and the top fixing rotating rod is screwed into the screw hole";

[0004] This type of structure adopts the method of adjusting pins and adjusting holes to realize the vertical adjustment of the load-bearing frame on the basis of combined fixation. However, this fixing method not only has complicated disassembly, assembly and adjustment processes, but also involves a large number of components and a high application cost. In addition, the base frame and the longitudinal rod are in a mutually nested relationship, which is only suitable for assembly and adjustment between the two, and does not have the technical effect of flexible assembly in multiple directions. Utility Model Content

[0023] In the above structure, the column 1 serves as a vertical supporting body, and a limit block assembly 3 composed of two vertical limit blocks 30 is provided at its corner position. Correspondingly, the end of the load-bearing arm 2 has an inner concave angle 4, and vertical limit grooves 40 are respectively provided on the two inner sides of the inner concave angle 4. During assembly, the inner concave angle 4 is aligned with the corner of the column 1, and the vertical limit grooves 40 are aligned with the vertical limit blocks 30 one by one, and then the load-bearing arm 2 is slid from top to bottom. Correspondingly, the vertical limit blocks 30 are inserted into the vertical limit grooves 40 from bottom to top. 0 and the vertical limit groove 40 can only slide relative to each other for a preset length, so that the inner concave corner 4 is clamped at the corner of the column 1. Compared with the method of clamping using an adjusting rod and an adjusting hole in the prior art, the utility model only needs vertical plugging to complete the installation, and the assembly process is simple and convenient. At the same time, the number of components involved is smaller, which simplifies the load-bearing frame structure and reduces the cost. In addition, by reasonably arranging a certain number of limit block assemblies 3 at each corner and length direction of the column 1, the multi-position and multi-directional installation requirements of the load-bearing arm 2 can be met, so it has more application flexibility.

[0024] In order to limit the vertical limit groove 40 and the vertical limit block 30 to each other, in this embodiment, Figures 2 to 4 As shown, the vertical limit block 30 is a wedge-shaped limit block, and the width of the vertical limit block 30 gradually increases from top to bottom, and the vertical limit groove 40 is a wedge-shaped limit groove, and the width of the vertical limit groove 40 gradually increases from top to bottom.

Specifically, a right angle recess is formed between the two straight side portions 300.

[0026] In this embodiment, a stopper 41 is provided at the upper end of the vertical limit groove 40. The stopper 41 has a supplementary limit function, which can improve the bearing capacity of the load-bearing arm 2. When the vertical limit block 30 slides into the vertical limit groove 40 for a certain length, the stopper 41 can abut against the top of the vertical limit block 30, so that the column 1 and the load-bearing arm 2 can be combined more reliably.

This structure can not only install the load-bearing arm 2 in multiple directions, but also flexibly adjust the height position of the load-bearing arm 2. In actual applications, multiple groups of the columns 1 and the load-bearing arms 2 can be arranged along the length direction or the width direction, so as to realize the flexible extension of the load-bearing frame and better meet the application requirements.
