1. Field of Invention

The present application relates to multi-directionally-engageable column combination structures and particularly to a structure with better assembly convenience and stability.

2. Description of Related Art

Various products, such as study desk, seat, compartment, shelf, cabinet, and elevated flooring and so on are generally supported with straight columns. These columns may be set in a direction perpendicular, or parallel to the ground or in another direction. Study desk, seat, and other components may be disposed on the columns by using fixing elements.

In order to provide assembly convenience, four or eight T-shaped grooves are arranged on a surface of the column in different directions and a T-shaped hook body is provided at an end of an external component. The T-shaped hook body may be embedded from one end of the column into the T-shaped groove and then moved to an appropriate position in the middle of the column for combination so that the hook body will not separate from the column along a radial direction of the column.

In the preceding assembly manner, it is required to perform assembly from the end of the column, resulting in assembly inconvenience. Further, when a hook body of another external component is present in the middle of the column and hinders assembly of another hook body, it is required to firstly take out the hook body of the external component and then assemble another hook body. Such assembly consumes much time.

Furthermore, at present, a U-shaped groove may be disposed on the column and the end of the external component is directly placed at the groove position of the column and then locked with a bolt. In this way, it is not required to perform insertion combination from the end of the column any more during assembly. However, the above combination manner will easily cause the external component to directly separate along the radial direction of the column when the bolt is loosened.
