[0001] The utility model relates to the technical field of rockers, in particular to a connecting structure between a column and a base. Background Art

[0002] Equipment such as rockers and dining chairs generally includes a main body and a support structure. The support structure is generally made of multiple sections of steel pipes disassembled and assembled. In the prior art, when transporting equipment such as rockers or dining chairs, the equipment needs to be disassembled and transported. However, since the ends of the steel pipes are relatively sharp, they are likely to scratch other objects during transportation, or the ends of the steel pipes are deformed due to collision, thus affecting the subsequent assembly of equipment such as rockers or dining chairs, and improvement is needed in this regard. Summary of the Invention

[0003] Aiming at the defects in the prior art that the ends of steel pipes are likely to scratch adjacent objects or the ends of steel pipes are deformed during transportation, the utility model provides a new connecting structure between a column and a base.

[0008] The reinforcement nut prevents the first fastener from being directly screwed onto the connecting member, thereby improving the connection strength between the first fastener, the connecting member and the base.

[0009] Preferably, in the above-described connection structure between a column and a base, the number of the third hole and the fourth hole is at least two, and the first hole and the second hole correspond to the third hole and the fourth hole respectively; an extension column extending outward is provided on the outer side wall of the base, and the second hole is provided on the extension column.

[0010] There are multiple first holes, second holes, third holes, and fourth holes, which realize multi-point fixation of the connecting parts, the base, and the column, and improve the stability of assembly of the column, the base, and the connecting parts; the connection length between the first fastener and the base is extended by extending the column, and the stability of the fixation of the base and the connecting parts is further improved.

[0011] Preferably, the above-mentioned connection structure between the column and the base also includes a locking cover and a second fastener, the locking cover is provided with a locking tube, the outer diameter of the locking tube is adapted to the maximum width inside the reinforcement nut, the locking tube is inserted into the fourth hole and connected to the end of the reinforcement nut, and the locking cover is fitted with the connecting piece; the locking cover is provided with a first locking hole, the connecting piece is provided with a second locking hole, and the second fastener passes through the first locking hole and is screwed into the second locking hole.

[0012] The locking cover is fixed to the connecting piece through the second fastener, the first locking hole and the second locking hole, which has the advantages of convenience and speed; the reinforcing nut is limited by the locking tube, which improves the stability of the first fastener being screwed on the reinforcing nut.

[0013] Preferably, the connection structure between the column and the base described above further includes a decorative cover, the base is provided with a mounting groove, the inner side wall of the mounting groove is provided with a plurality of mounting holes, the decorative cover is provided with buckles corresponding to the mounting holes one by one, the decorative cover is inserted into the mounting groove and adapted to the shape of the mounting groove, the buckles pass through the corresponding mounting holes and are snap-fitted; the locking cover is provided with a clearance cavity, the clearance cavity is opposite to the adjacent mounting hole, and the end of the adjacent buckle is inserted into the clearance cavity.

[0014] The decorative cover improves the overall aesthetics, and the decorative cover can be quickly and stably assembled on the base through the snap fit with the mounting hole. The make way cavity is used to avoid the mounting hole relative to the make way cavity, making it convenient to pass the snap through the mounting hole.

[0015] Preferably, in the above-mentioned connection structure between a column and a base, the upper end of the connection piece is U-shaped.

[0016] The upper end of the connecting piece is U-shaped, so as to play a role of contraction and yielding when the upper end of the connecting piece is inserted into the column, facilitating the insertion and cooperation between the upper end of the connecting piece and the column, and further improving the convenience during the assembly of the connecting piece and the column.
