Abstract
A load cell scale has a load cell part formed in a columnar shape, the load cell part having a upper surface extending along a longitudinal axis and a lateral surface intersecting with the upper surface, and a stopper part configured to restrict deformation occurring in the load cell due to a load exceeding a predetermined value and applied to the load cell, wherein the load cell part has a strain portion capable of elastically deforming and the strain portion penetrates the load cell part from the lateral surface in a short direction orthogonal to the longitudinal direction, and wherein the stopper portion is provided to be connected to the lateral surface of the load cell part.
Claims14
A load cell scale, comprising:
- a load cell part formed in a columnar shape, the load cell part having a upper surface extending along a longitudinal axis and a lateral surface intersecting with the upper surface, and the load cell part having a first load cell with a first weighting and a second load cell with a second weighting, and
- a stopper part configured to restrict deformation occurring in the load cell due to a load exceeding a predetermined value and applied to the load cell part, the stopper part being configured to correspond to either of the first load cell or the second load cell,
- wherein the load cell part has the first load cell and the second load cell to be disposed along a longitudinal direction or a height direction,
- wherein the load cell part has a strain portion capable of elastically deforming and the strain portion penetrates the first load cell and the second load cell from the lateral surface in a short direction orthogonal to the longitudinal direction, and
- wherein the stopper part is a plate-shaped member formed to extend along the longitudinal direction, the stopper portion comprising:
- a fixing-end portion fixed to the lateral surface of the load cell;
- and
- a free-end portion separating from the fixing-end portion along the longitudinal axis, the free-end portion being configured to restrict the elastic deformation of the load cell part due to the load in a state when the fixing-end portion is fixed to the lateral surface.
