Description

Technical Field

[0001] The utility model belongs to the technical field of commercial facilities, and in particular relates to a column connection structure for shelves. Background Art

[0002] Shelves are widely used in people's daily lives. Their technology is relatively mature and their structures vary greatly. They are mainly composed of columns and shelves. Depending on the load of the shelves, the columns of light-load shelves are generally only single-column support structures directly connected to the shelves, while the columns of heavy-load shelves usually have multiple diagonal braces added between two adjacent columns. The multiple diagonal braces are used to improve the strength and stability of the columns, and the multiple diagonal braces form multiple triangular structures between adjacent columns. With the continuous changes in the international market, the length of a single column of shelves sold by e-commerce is strictly limited. The industry can only use a structure that reassembles segmented columns to shorten the volume of packaging and transportation in logistics. However, the diagonal brace has high requirements for the columns. The stress points of the triangular support structure are distributed at the connection position between the column and the diagonal brace, and the stress magnitudes are different. The stress at the connection of the segmented column is relatively weak. In actual use, when the upper and lower columns are stressed separately, the column connection is likely to be broken under the action of shear force, especially when the shelves are loaded with heavy goods. There are great safety hazards and it cannot meet the needs of consumers. In addition, the diagonal brace is usually fixed to the column with bolts and other accessories, which has the disadvantages of a large number of parts, troublesome installation, and low assembly efficiency.

[0003] In view of the above problems, it is necessary to design a shelf column connection structure that is simple in structure, low in cost, has few parts, can quickly connect columns and avoid the segmented columns from being broken due to uneven force, and can ensure safe and reliable use. To this end, the applicant has cleverly designed this technical solution. Utility Model Content
