Description

Technical Field

[0001] The present application relates to the field of polymer material technology, and in particular to a luggage case beverage placement rack and a preparation method thereof. Background Art

[0002] Nowadays, when people are on business trips or traveling, in order to carry the necessary luggage, they usually choose to use a suitcase to carry. However, due to the large or heavy luggage, it is usually inconvenient to carry beverages such as coffee and juice. Therefore, in order to solve the problem that it is inconvenient to hold a cup or a beverage in the hand due to the large or heavy luggage when people travel, a luggage beverage placement rack structure is added to the existing luggage.

[0003] A luggage case beverage rack generally consists of a guard frame and a support plate installed on a connecting plate. The cup is placed from top to bottom from the guard frame and supported by the bottom through the support plate, so that the cup can be stably placed in the cup. In order to prevent the beverage rack from protruding out when not in use, the guard frame and the support plate can be set to a foldable structure. When the cup holder is not in use, the guard frame and the support plate can be folded and embedded on the side wall of the luggage case.

[0004] However, in daily use, the beverage rack is easily damaged due to the impact of the suitcase tipping over, collision or its own low load-bearing capacity, and the damaged beverage rack cannot be replaced individually, which affects the consumer's experience of use and limits the development of this type of suitcase. Summary of the invention

[0005] In order to improve the load-bearing capacity and drop resistance of a luggage case beverage rack, the present application provides a luggage case beverage rack and a preparation method thereof.
