The use of shelving rollers greatly improves the operational efficiency of warehousing and supermarkets, reduces labor costs, and makes the management of goods more convenient and efficient. They are one of the important components of shelving. The rollers are connected using a roller connection structure during the installation process on the shelving.
[0003] However, when installing and connecting roller components for shelving, the connection structure is generally a single-layer iron sheet, which has poor main structural strength and is prone to deformation and twisting under stress. This is a shortcoming and makes it difficult to strengthen the internal structure of the roller connection structure.
[0004] Now, a novel connection structure for the rollers of the shelving is proposed to address the above-mentioned shortcomings. Utility Model Content
