Description

Technical Field

[0001] The utility model relates to the technical field of electronic scales, and particularly relates to a weighing sensor assembly for an electronic scale which is convenient to install. Background Art

[0002] An electronic scale is a kind of weighing instrument, which is a tool for measuring the mass of an object by using Hooke's law or the lever balance principle of force. According to the structural principle, it can be divided into three categories: mechanical scales, electronic scales, and electro-mechanical combined scales. An electronic scale mainly consists of a load-bearing system (such as a weighing pan and a scale body), a force transmission and conversion system (such as a lever force transmission system and a sensor), and a display system (such as a dial and an electronic display instrument).

[0003] During the use of an electronic scale, when the object to be weighed directly falls on the weighing pan of the electronic scale, it is easy to cause an impact on the electronic scale. When the impact force of the object to be weighed is too large, it is easy to damage the weighing sensor. In the prior art, a sensor protection component is generally added, but during long-term use, the sensor protection component inside the electronic scale will still be deformed and the weighing sensor will be inaccurate, and it is necessary to open the electronic scale for repair or replacement in time. The existing electronic scales are mostly fixed with bolts, which are inconvenient to open for repair and replacement, and there are problems. Content of the Utility Model

Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0022] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right", etc. can be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.
