Description

Technical Field

[0001] The utility model relates to the technical field of dining trolley push handles, in particular to an aviation dining trolley push handle. Background Art

[0002] The dining cart is one of the most critical kitchen equipment on the aircraft. There are two types: hot dining cart and cold dining cart. Hot dining carts are usually used to heat food. They are equipped with steam heating equipment and electric heating equipment, which can heat a variety of foods. Cold dining carts are used to serve cold meals. They are equipped with transparent refrigerators to store ingredients and drinks. Among the non-critical parts of civil aviation, aluminum aviation dining carts are widely used.

[0003] When the dining cart is in use, it is generally moved by pushing the handle. Since the airplane is prone to bumps during flight, in order to prevent the service staff from sliding between the hands and the handle when pushing the dining cart, friction protrusions are generally added to the surface of the handle during the production process to improve stability during use. However, after a period of use, dust and foreign matter are easily accumulated in the gaps between the friction protrusions, and the friction protrusions are fixed on the handle and cannot be disassembled, which is inconvenient to clean.
