Description

Technical Field

[0001] This utility model relates, and more particularly to, an extension table and its outdoor multi-functional folding table. Background Technology

[0002] With the increasing popularity of outdoor activities, folding tables have become common equipment for camping, picnics, and other similar settings due to their portability. However, traditional outdoor folding tables have significant shortcomings in terms of functional expandability, flexibility of use, and environmental adaptability, specifically manifested in the following problems:

[0003] Single function

[0004] Most existing folding tables have fixed tabletops and lack modular expansion capabilities. Users need to carry additional accessories such as shelves and stove supports, resulting in scattered equipment and inconvenience. For example, when cooking, the stove and tableware need to be placed separately, which takes up space and is cumbersome to operate.

[0005] Poor splicing stability

[0006] When multiple tables are joined together, they often rely on simple clips or hooks for connection. However, these are easily separated due to external forces causing the joints to come apart, or even resulting in uneven tabletops, which affects safety and comfort during use.

[0007] Insufficient heat dissipation and lightweight design

[0008] Traditional desktops are mostly made of solid materials (such as wood or plastic), which can cause heat to accumulate when heated devices (such as portable stoves) are placed on them, posing a risk of burns. At the same time, the heavy structure increases the burden of carrying them and makes it difficult to meet the requirements of lightweight design.

[0009] Durability and safety defects

[0010] Some products are made of materials with poor water resistance and are prone to corrosion when exposed to humid environments for a long time; the tabletop surface is smooth and items placed on it are easy to slide, posing a risk of tipping over.
