CN-224216154-U - Overload protection device for elastic element in weighing sensor

Abstract

The utility model provides an overload protection device for an elastic element in a weighing sensor, which relates to the technical field of weighing sensors and comprises an end head, wherein an elastic element main body is fixed at one end of the end head, supporting plates are arranged at two ends of the inner bottom wall of the elastic element main body, and two matched triangular sliding blocks are arranged between the two supporting plates. Through adjusting the adjusting screw, two triangle-shaped sliders of drive move, make it tightly with the backup pad top, this kind of tight effect in top provides stable holding power for the backup pad, two backup pads of high laminating about, support four grooved weak points through four lugs accurately, when the pressurized, because the tight top of triangle-shaped slider, the backup pad can not warp easily, and the synergism of upper and lower backup pad, make whole face can keep leveling under the pressure effect, when bearing pressure, can ensure that the weak point of structure obtains reliably supporting, avoid leading to structural deformation or damage because of local atress is uneven, promote safety in utilization.
