Description

Technical Field

[0001] The utility model belongs to the technical field of platform scales, and in particular relates to a supporting platform scale. Background Art

[0002] The history of platform scales can be traced back to ancient civilizations, when people used simple scales for measurement. However, this type of scale requires direct vision to judge the state of balance, is easily disturbed by human factors, and has low accuracy.

[0003] With the progress of society and science and technology, people's requirements for accuracy and efficiency are constantly increasing. In the Middle Ages, some large markets began to use floor scales, which consisted of a platform on the ground and a weighing body above. They could display the weighing results more intuitively, greatly improving the accuracy and efficiency of weighing. However, floor scales generally use spring-type or mechanical force sensors to sense and record weighing results. There are problems with the response speed and stability of these sensors, so there are still certain limitations in terms of measurement accuracy and working stability.

[0004] Therefore, in order to solve the above technical problems of weighing stability, this application adopts a supporting platform scale equipped with a balancing mechanism. The structure completes the load-bearing layer through the upper and lower plates, and disperses the gravity through the balancing mechanism in the middle section of the two sets of plates, and at the same time disperses the gravity to the buffer coupling for further buffering process. During the buffering process, the "cross" arm is used to concentrate the gravity on the pressure plate, and the sensor is used to display the gravity data. Summary of the invention

[0007] Four groups of buffer shafts are vertically extended from the bottom end surface of the balancing plate, and the buffer shafts are sleeved in the shaft sleeves of the balancing mechanism.
