[0001] This utility model relates to the field of office equipment, and in particular to a support column connection structure. Background Technology

[0002] In order to ensure the stability of the legs in current office desks and chairs, at least one crossbar is used to fix two legs together. The crossbar is perpendicular to the legs. The structure is shown in patent publication document CN218832228U. In this structure, the crossbar and the legs are welded together. Although welding ensures the stability of the entire structure, it is not conducive to disassembly, packaging and transportation. Therefore, the office desks and chairs shown in CN218832228U are not suitable for packaging and transportation. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a support column connection structure. By setting a locking hook and a locking part, the locking action of the locking hook and the locking part temporarily locks the connecting rod and the column. At the same time, a locking plate is used to fix the connecting rod and the column together. The locking plate itself is installed in a detachable manner, and only the locking plate needs to be removed when disassembly is required.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A support column connection structure includes a column, a connecting rod, a locking piece, and fasteners. The outer wall of the column is provided with a locking part, and the connecting rod is provided with a locking hook. The locking hook engages with the locking part. The locking piece is L-shaped, with one end embedded in the locking part and the other end pressed against the outer wall of the connecting rod. The fasteners engage with the locking piece and the connecting rod.

[0006] In this specific connection structure, the fastener can be a screw, a bolt, or even a locating pin.

[0007] The specific connection method of this structure is as follows: First, the connecting rod and the column are engaged through the engagement of the hook and the engagement part. After the engagement, the column and the connecting rod are temporarily locked. After temporary locking, the L-shaped locking piece is inserted into the engagement part, with one end of the L-shaped locking piece locked to the engagement part. Then, the locking piece is fixed to the connecting rod with the fastener, thus completing the fixation of the locking piece and the connecting rod. Since one end of the locking piece is engaged with the engagement part, and the other end of the locking piece is fixed to the connecting rod with the fastener, the connecting rod and the column are now fixed together, providing good connection stability. When it is necessary to disassemble the connection between the column and the connecting rod, simply remove the fastener from the locking piece. This will release the lock between the connecting rod and the column. By sliding the connecting rod, the engagement part will disengage from the hook, thus completing the disassembly of the column and the connecting rod.

[0008] In summary, this connection structure uses a locking hook and a locking part to temporarily lock the connecting rod and the column together. At the same time, a locking plate is used to fix the connecting rod and the column together. The locking plate itself is installed in a detachable manner, and only the locking plate needs to be removed when disassembly is required.

[0009] Optionally, the engaging part is a semi-U-shaped engaging part, and the engaging hook is a right-angled bent plate-shaped engaging hook.

[0010] The use of a semi-U-shaped locking part and a right-angle bent plate-shaped locking hook ensures that the locking hook can slide smoothly into or out of the locking part.

[0011] Optionally, there are two engaging parts, which are parallel and do not contact each other, and the number of engaging hooks is equal to the number of engaging parts.

[0012] Specifically, each column is equipped with two locking parts, and each end of the connecting rod is equipped with two locking hooks, so that the connection between the connecting rod and the column is more stable.

[0013] Optionally, a positioning groove is provided on the outer wall of the connecting rod, and one end of the locking piece is located in the positioning groove.

[0014] The purpose of the positioning groove is to accommodate one end of the locking piece, thereby facilitating the loosening and tightening of fasteners and ensuring that the locking piece remains stable and does not wobble when loosening and tightening fasteners.

[0015] Optionally, the connecting rod is perpendicular to the column.

[0016] Optionally, the column is a cylindrical column, and the connecting rod is a hollow square tube connecting rod.

[0017] Optionally, both ends of the connecting rod are provided with locking hooks, and the locking hooks at both ends of the connecting rod are respectively engaged with locking parts on different columns.

[0018] Optionally, the fastener is perpendicular to the connecting rod, and the fastener is parallel to the column.

[0019] A table and chair set, including the support column connection structure as described above.

[0020] The specific tables and chairs can be tables, chairs, or other office supplies that use this connection structure (such as storage cabinets or shelves).

[0021] The beneficial effects of this utility model are: by setting a locking hook and a locking part, the locking action of the locking hook and the locking part can temporarily lock the connecting rod and the column. At the same time, the locking piece can fix the connecting rod and the column together. The locking piece itself is installed in a detachable manner, and only the locking piece needs to be removed when disassembly is required. Attached Figure Description
