Field of the Invention
[0001] 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
[0002] 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
[0003] 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.
[0004] 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.
[0005] 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.

Detailed Description of the Embodiments
[0007] A split mounting type square column assembly for exhibition equipment, comprising
a square column I , 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 outside of the area of
connecting groove 11 on outside surface of said square column 1; said embedded type
supporting frame 2 comprises a supporting frame body 21, a spring pin 22, and a spring
keyway 23; said spring pin 22 is located on said spring keyway 23; in the initial
state, said spring pin 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
