DETAILED DESCRIPTION OF THE INVENTION

(4) Referring to FIGS. 1 to 4, which are preferred embodiments of the frame hooking and combining structure of the present utility model, this embodiment is for illustrative purposes only, and is not limited by the patent application. The frame hooking and combining structure comprises a column 10, which has a polygonal cross section. Each side of the column 10 is formed with at least one first through hole 11, and at least one second through hole 11 which is parallel to at least one first through hole 11, wherein at least one first through hole 11 and the at least one second through hole 12 longitudinally correspond to the column 10. At least one first support rod 20 is provided to hook the column 10. The two ends of the at least one first support rod 20 are respectively extended with a fastening part 21, and the free end of the fastening part 21 is connected with at least one first hook 22. The at least one first hook 22 is hooked and positioned to the bottom edge of the at least one first through hole 11, and the fastening part 21 is attached to a corresponding end surface of the column 10. The fastening part 21 is formed with at least one hollow portion 23, and the area of the at least one hollow portion 23 at least partially covers the area of the at least one second through hole 12. The at least one first support rod 20 is a tubular structure body with a rectangular cross section, and the fastening part 21 is fixed to the inner wall of the long side of the at least one first support rod 20. At least one second support rod 30 is provided to hook the column 10. The two ends of the at least one second support rod 30 are respectively extended with a second hook 31, and the free end of the at least one second hook 31 penetrates through the at least one hollow portion 23 and the at least one second through hole 12 into the interior of the column 10, and is locked to the bottom edge of the at least one second through hole 12, thereby clamping to the corresponding fastening part 21 relative to the column 10. The at least one second support rod 30 is a tubular structure body with a rectangular cross section, and the at least one second hook 31 is fixed to the inner wall of the long side of the at least one second support rod 30.

(5) In a preferred embodiment of the present utility model, the at least one first through hole 11 is an upper-wide and lower-narrow structure, so that the at least one first hook 22 is firmly caught at the bottom edge of the at least one first through hole 11. The at least one second through hole 12 is an upper-wide and lower-narrow structure, and the bottom of the at least one second hook 31 is formed with a notch 311 extending upwardly. The at least one notch 311 is an upper-narrow and lower-wide structure, so that the at least one second hook 31 is firmly clamped at the bottom edge of the at least one second through hole 12, and further clamped to the corresponding fastening part 21 relative to the column 10. In addition, the cross section of the column 10 is selected from one of a regular polygon and a rectangle.

(6) In a preferred embodiment of the present utility model, if the cross sections of the at least one first support rod 20 and the at least one second support rod 30 are rectangular, in order for the at least one first support rod 20 and the at least one second support rod 30 to have a flat appearance, the outer side surface of the fastening part 21 and the outer wall of the long side of the at least one first support rod 20 are on the same plane. The outer side wall of the at least one second hook 31 and the outer wall of the long side of the at least one second support rod 30 are located on the same plane.

(7) In a preferred embodiment of the present utility model, in order for the at least one first support rod 20 and the at least one second support rod 30 to have better bonding strength with the column 10, the at least one first through hole 11 is longitudinally arranged in groups of two on the column 10. The at least one second through hole 12 is longitudinally arranged in groups of two on the column 10, and each first through hole 11 horizontally corresponds to a corresponding second through hole 12. The free end of the fastening part 21 is connected with two up-and-down longitudinally arranged first hooks 22, and the fastening part 21 is formed with two up-and-down longitudinally arranged hollow portions 23. Two ends of the at least one second support rod 30 are respectively extended with two up-and-down longitudinally arranged second hooks 31.

(8) In addition, the preferred embodiment of the present utility model further includes at least one series-connecting member 40. The at least one series-connecting member 40 is axially connected to two coaxial columns 10.

(9) To sum up, compared to the traditional structure, the present utility model in the design of the structure does have the following advantages. In the preferred embodiment of the present utility model, the at least one first support rod 20 and the at least one second support rod 30 all are selected from the rectangular metal pipes, and the mounting of the at least one first support rod 20 and the at least one second support rod 30 all adopt a mode in which the long sides are perpendicular to the force bearing surface. Therefore, a better support strength can be provided and the thickness of the at least one first support rod 20 and the at least one second support rod 30 can be greatly reduced to lower the material purchase cost. Moreover, the first support rod 20 and the second support rod 30 and the fastening part 21 and the second hook 31 of the present utility model are respectively processed, and then bonded together by welding. Because the first support rod 20 and the second support rod 30 are acquired from commercially available rectangular pipes, length can be arbitrarily processed and cut according to the user's needs. Therefore, it suffices to prepare two molds for processing the fastener part 21 and the second hook 31, which can greatly reduce the cost of the mold. In the process of processing, a plurality of pipes can be cut at one time, which is also of great help for increasing production capacity.
