a weighing device

Abstract

A weighing device comprises a measuring cup and a fixing base used for fixing the measuring cup. The weighing device is characterized in that a spring is arranged between the measuring cup and the fixing base, levers are further arranged in the fixing base, weights are placed in the measuring cup, the outer ends of the levers are made to be exposed out of a boss of the fixing base through extrusion of the spring between the measuring cup and the fixing base and linkage between the measuring cup and the levers, and the weighing effect of the weighing device is realized according to the number of the levers which are exposed outside. According to the weighing device, when a certain number of weights are placed in the measuring cup, the measuring cup will drop downwards along a T-shaped groove of the fixing base and compress the spring, when the weight reaches the preset weight, the measuring cup will press the inner ends of the levers so as to enable the levers to rotate along a rotation shaft to enable the outer ends to turn up and be exposed out of the boss, and the weight of objects in the measuring cup can be known by counting the number of the levers which are exposed outside and multiplying the unit weight of each exposed lever. The weighing device has the advantages of being simple and reasonable in structure, convenient and fast to install, safe, reliable, low in cost and the like.

Description

technical field [0001] The utility model relates to a weighing device, in particular to a weighing device suitable for visually impaired persons. Background technique [0002] At present, weighing instruments on the market are all displayed with scales or numbers, which are difficult for the visually impaired to see clearly. For example, measuring cups used in home appliances are displayed with scales, and are generally small, exquisite and transparent. It is difficult for visually impaired people to see the volume of food in the measuring cups; and scales are scales plus numbers, and additions are required during operation. Even the electronic scales with higher costs still use smaller LED screens to display numbers, which cannot meet the requirements of the visually impaired. Therefore, it is necessary to further improve the weighing device of the above structure. Utility model content [0003] The purpose of this utility model is to provide a weighing device that can ...

For example, measuring cups used in home appliances are displayed with scales, and are generally small, exquisite and transparent. It is difficult for visually impaired people to see the volume of food in the measuring cups; and scales are scales plus numbers, and additions are required during operation. code, the visually impaired cannot use it; even the high-cost electronic scale uses a small LED screen to display numbers, which cannot meet the requirements of the visually impaired.
