Description

FIELD OF THE INVENTION

The present invention relates to an assembly of combined type exhibition equipment, particularly to a split mounting type square column assembly.

BACKGROUND OF THE INVENTION

The prior art employs guide rails in square columns and internally assembled connecting pieces. The connecting pieces are fixed by screw fastening. However, since the retaining screws must have countersunk heads, which must pass through existing grooves to implement tightening, the grooves have to be cut partially to enable the screws to pass through; as the result, there is a potential safety hazard, i.e., if the Operation points of forepaws of connectors in other adjacent supports are right in the cut part of the groove, the connection points are not connected actually or false connected. For exhibition supports, the consequence may be connection failure of the supporting structure and may result in personal injury.

SUMMARY OF THE INVENTION

The present invention provides a split mounting type square column assembly that facilitates assembling of the exhibition equipment and improves safety and reliability of the exhibition equipment.

The present invention employs the following technical scheme:

A split mounting type square column assembly for exhibition equipment, comprising a square column 1, a embedded type supporting frame 2 and a connecting lock 3; wherein, said connecting lock 3 is removable located in said embedded type supporting frame 2; said embedded type supporting frame 2 is removable located in said square column 1, at least one outside surface of said square column 1 has a connecting groove 11, and a quantity of positioning mounting holes 12 is arranged on the outside surface of said square column 1 outside of the area of connecting groove 11; said embedded type supporting frame 2 comprises a supporting frame body 21, a spring cotter 22 and a spring keyway 23; said spring cotter 22 is located on said spring keyway 23; in the initial state, said spring cotter 22 overhangs from said spring keyway 23, said spring keyway 23 is located on said supporting frame body 21, therefore the moving pathway of said spring cotter 22 could pass through the positions of said positioning mounting holes 12 when said embedded supporting frame 2 is pushed in or out.

Compared to the prior art, the present invention has the following advantages:

• (1) In the present invention, the connection between the square column and the embedded type supporting frame is arranged outside of the area of connecting groove that is designed to connect other parts of the exhibition equipment; therefore, the present invention ensures completeness or integrity of the connecting groove, so that it is unnecessary to consider the effect of assembling holes in the connecting groove when said exhibition equipment is assembled, and reliable connection can be implemented at any position in said connecting groove; as the result, the present invention can facilitate assembling of the exhibition equipment and improve safety and reliability of the exhibition equipment.
• (2) The plates that constitute the square column are removable connected, and thereby provide more convenience for assembling of the exhibition equipment.
• (3) The present invention employs a spring pin for connection; the spring pin can implement accurate fitting between internal connecting pieces (inserts) and outer surface of the profile, and thereby ensures required accuracy. Furthermore, it is common knowledge that it is much easier to work out locating holes on outer walls than on complex shapes (e.g., walls with uneven wall thickness, half openings, cantilevers, or bevel surfaces, etc.). Employ spring pin structure can avoid fixing holes or fabrication holes on outer finished surfaces; since the pin structure level up the pin hole after it is assembled to the section of profile, it can maximize appearance perfection. In addition, since the mounting point of the structure is above or below the joint, the structure can avoid adverse effect to the finishing work on left and right surfaces at the joint as far as possible.
