Description

Technical Field

[0001] The utility model relates to the technical field of dining table accessories, in particular to a tabletop extension structure. Background Art

[0002] An outdoor aluminum alloy dining table is a dining table designed for outdoor environments. It is usually made of aluminum alloy and is lightweight, durable, and easy to carry. Aluminum alloy not only has high strength, but can also effectively resist the effects of bad weather, making it suitable for outdoor use. Aluminum alloy has high strength and corrosion resistance, can withstand large weights, and is suitable for outdoor use. Aluminum alloy dining tables are usually designed to be foldable or removable, and their tabletops are also removable and foldable, making them easy to carry and store. However, the tabletop area of ​​an aluminum alloy dining table is limited, and is usually used in conjunction with an expansion structure. The expansion structure is installed with a bracket, and the tabletop can be expanded when needed to meet the needs of more people dining or working. However, the common desktop expansion structures on the market have poor adaptability after splicing and expansion, and are prone to deviations from the main tabletop height. They are also relatively weak overall, with limited load-bearing strength, and the expansion structure has limited practicality, making them more difficult to clean. Utility Model Content
