[0002] As living standards continue to improve, more and more people are focusing on fitness. Barbell racks are a type of fitness equipment, primarily used for strength training exercises like squats and bench presses. To address this, home barbell racks have emerged. While these have reduced size and weight, and are more affordable for fitness enthusiasts, they still take up considerable space in generally small homes.

[0003] For example, the patent with the national authorized patent announcement number CN219050231U discloses a foldable barbell rack, comprising a bottom support rod, a column frame, a barbell bracket and a connecting seat, wherein two bottom support rods are arranged in parallel; the column frame has two columns, each mounted on a corresponding bottom support rod; the barbell bracket has two columns, each mounted on the top of a corresponding column frame; the connecting seat is located between the two bottom support rods, and both sides of the connecting seat are connected to the bottom support rod on the corresponding side through a connecting rod assembly, and the connecting seat and the bottom support rod form a parallelogram connecting rod assembly through the connecting rod assembly. In the embodiment of the utility model, the connecting seat connects the two bottom support rods through the connecting rod assembly, so that the two bottom support rods can move toward each other as the connecting rod assembly swings, reducing the distance between the two, and forming a parallelogram connecting rod mechanism through the connecting rod assembly, so that the two bottom support rods moving toward each other remain parallel, and the distance between the two bottom support rods can be minimized to the greatest extent, and finally the barbell rack is folded to a smaller size, eliminating the substantial occupation of home space, and is more convenient to unfold and fold.

[0004] However, the above-mentioned foldable barbell rack requires staff to frequently fold and unfold it for use at home, and the staff needs to perform multiple steps of folding and locking the rack during the folding and unfolding process, making it impossible to quickly unfold and fold it. Utility Model Content
