Abstract

The present invention discloses a multifunctional knockdown rack structure, mainly comprising a main shaft and a plurality of inserting members, wherein the main shaft forms by stamping a plurality of ring edges at many sections on the surface of the tube member of the main shaft; the inserting member has an opening with a diameter slightly smaller than that of the tube member of the main shaft, and forms an interior hollow that exactly fits into the ring edge, and there are a blocking section and a supporting section respectively at the upper end and lower end of the interior hollow that fit into the tube member of the main shaft. The upper end and lower end respectively fit in the blocking section and the supporting section; such supporting section is coupled to the interior hollow having a anti-pressure section at an appropriate distance (this section is one empty section having no restrictions). The anti-pressure section offers an unrestricted accommodation to the ring edges of the main shaft; as the ring edges slide into the interior hollow until they reach the blocking section, and such blocking section will tightly grasp the ring edge forming a tight coupling to the ring edge surface with the interior hollow. The supporting section at the lower end also tightly presses the external rim of the tube; such arrangement can fix the inserting members to the ring edge of the main shaft in position, and can achieve the purpose of being a multifunctional, all purpose, safe, and reliable assembly.

Dependent claims

A multifunctional a knockdown rack structure, comprising:

a main shaft having a tubular member and a plurality of rings integrally formed on a surface of said tubular member, said rings being formed in different axially-disposed locations;
and
a plurality of C-shaped inserting members positionable around said tubular member and engagable with a respective ring, each said inserting member including:
an intermediate section disposable around the respective ring, the intermediate section having an inner surface having a radius of curvature that is essentially the same as a radius of curvature of the respective ring so that when the intermediate section is disposed around the respective ring, the ring freely fits within a hollow space of said intermediate section;
a blocking section disposed at an upper portion of said intermediate section, said blocking section projecting inwardly beyond the inner surface of the intermediate section so that when the intermediate section is disposed around the respective ring, the blocking section is disposed above and abuts against the respective ring, to prevent said inserting member from sliding downward along said tubular member;
and
a supporting section disposed at a lower portion of said intermediate section, said supporting section projecting inwardly beyond the inner surface of the intermediate section so that when the intermediate section is disposed around the respective ring, the supporting section is disposed below the respective ring and tightly presses the outer surface of said tubular member to support said inserting member against said tubular member.
