Description

Technical Field

[0001] The utility model relates to the technical field of luggage scales, in particular to a precise measuring luggage scale. Background Art

[0002] A luggage scale is a portable device used to measure the weight of luggage. You can hang the luggage on the scale and read the weight of the luggage. The main function of a luggage scale is to help people accurately measure the weight of their luggage. It can help passengers understand the weight of their luggage in advance, avoid extra charges due to overweight, and provide convenience and save time.

[0003] At present, some existing luggage scales cannot tightly connect the hook of the luggage scale with the luggage when in use, and the weight of the luggage cannot be completely transferred to the hook of the scale body, which may cause inaccurate weighing data. In the case of continuous weighing, the luggage scale is in a working state for a long time, which will cause the internal temperature to rise.

[0004] Therefore, those skilled in the art provide a precise measuring luggage scale to solve the problems raised in the above background technology. Utility Model Content
