Description

Technical Field

[0001] The utility model belongs to the technical field of weighing, and in particular relates to a weight detection object-carrying device of a weighing sensor. Background Art

[0002] A weighing sensor is a device that converts a mass signal into a measurable electrical signal output. It can be divided into several styles according to its shape, such as S-type, cantilever type, spoke type, plate ring type, diaphragm box type, bridge type, column type, etc. Among them, column-type weighing sensors are widely used in various electronic weighing equipment such as various truck scales, track scales, axle weight scales, and tank scales. It generally includes a bearing base, an elastic body, a pressure head, and a loading plate. The elastic body is columnar, and a strain gauge is arranged on the elastic body. The elastic body is fixed on the bearing base, the pressure head is arranged at the upper end of the elastic body, and the loading plate is arranged on the pressure head. When weighing, the object is placed on the loading plate, so that the load is applied to the pressure head and transmitted to the elastic body through the pressure head. After the elastic body is subjected to the load, a certain deformation will occur. The strain gauge arranged on the elastic body can deform with the deformation of the elastic body. The strain gauge converts the deformation into an electrical signal and transmits it to the central control system. After the central control system calculates and processes, it can obtain the actual weight data of the object. However, in actual use, the connection methods between the elastomer and the bearing base, as well as between the pressure head and the loading plate are mostly welding or bolting, and the elastomer and the loading plate cannot be disassembled and assembled separately. It is not convenient to flexibly replace them when there is a problem with the elastomer or the loading plate is damaged or the size is not suitable.
