Description

TECHNICAL FIELD

[0001] The utility model relates to a connecting structure, in particular to a rod body connecting structure. BACKGROUND

[0002] In the technical field of table frame, the stability and installation convenience of the connecting structure between the cross beam and the leg frame of the table frame are important design considerations.

[0003] In the prior art, the steel pipe joint on the steel pipe cross beam and the steel leg frame of the assembled table frame is usually connected directly by bolts, that is, a reserved hole is formed on the surface of the steel pipe joint and the steel pipe cross beam, and a machine screw and a machine nut are used for fixing. Although this connection method can achieve basic structural fixation, it has significant deficiencies in actual application.

[0004] The specific shortcomings are as follows: on the one hand, bolt connection relies on the accurate alignment of the reserved hole, and the relative position of the steel pipe cross beam and the steel pipe joint needs to be adjusted repeatedly during installation, especially when the two are square tubes and are placed vertically, the hole alignment requires a lot of time and manpower, and the installation efficiency is low. On the other hand, bolt connection requires the use of tools for tightening operation, which has high requirements for the operation accuracy of the installer. If the tightening force is uneven or there is a slight deviation in the hole position, it is easy to cause the steel pipe cross beam and the steel pipe joint to be skewed or stress concentrated, affecting the stability of the overall structure of the table frame. In addition, for scenes that need to be frequently disassembled or assembled on a large scale, the cumbersome steps of bolt connection further highlight its convenience defects, which is difficult to meet the needs of modern furniture for rapid installation and flexible adjustment.

[0005] Therefore, there is an urgent need for an improved scheme that can ensure connection strength, simplify installation process and improve assembly efficiency to overcome the technical bottleneck of inconvenient connection of the steel pipe cross beam and the steel pipe joint in the prior art.
