[0002] Beam-type storage shelves are professional storage shelves for the purpose of storing and retrieving palletized goods. They are composed of columns and beams. The beam-type shelves have a simple structure, are safe and reliable, and the columns are the main load-bearing columns that support the shelves. The columns are mainly hollow structures. After the splicing is completed, the top of the columns needs to be covered with heads to prevent dust and debris from entering the columns and affecting the supporting capacity of the columns.

[0003] Existing heads are generally made according to the inner diameter of the column. Users usually press them directly into the column during installation. The connection between the head and the inner wall of the column is unstable. When the shelf is moved, the head is often lost, which requires additional customization of heads of corresponding sizes to be installed on the column, which is time-consuming and labor-intensive and has low practicality.

[0004] Therefore, we propose a column head to solve the above problems. Utility Model Content
