Problems solved by technology

[0005] However, in the above-mentioned prior art load cell, the housing has an integral block structure and is not provided with means for stopping the elastic deformation of the elastically deformed portion due to the applied load. Therefore, if the load exceeds a predetermined The load at the maximum load value exceeds the allowable elastic deformation value of the case due to the application of the excess load, and as a result, the case exceeds the recovery yield point, and thus, when the load applied to the case is released, the case elastically deformed cannot return to its original state, cause damage to the load cell

Embodiment Construction

[0027] Hereinafter, the present invention will be described with reference to the drawings as follows.

[0028] like figure 1 As shown, the load cell according to an embodiment of the present invention includes a housing 10 , a plurality of through portions 20 , a first slit portion 30 and a first sensor unit 40 .

[0029] The housing 10 is in the shape of a rectangular block and includes a first housing part 11 and a second housing part 12. The bottom surface of the first housing part 11 is flat so as to be closely fixed to the ground, and the second housing part 12 It is integrally connected with the first shell part 11 , and flows down to a certain height according to downward pressure, and rises to the original state when the pressure is released.

[0030] Wherein, the bottom surface of the second shell part 12 has a structure separated from the ground by a certain height, so as to be able to flow up and down to a certain height. A placement plate for placing a measureme...

Abstract

The invention relates to a pressure measuring element which is characterized by comprising the components of a housing which comprises a first housing part and a second housing part, wherein the firsthousing part is fixed to ground, the second housing part is integrated with the first housing part and drops and flows by a certain height according to a downward applied pressure, and when the applied pressure is released, the second housing part rises and flows to an original state; a plurality of through parts which are separated from one another by a certain distance and divides the first housing part and the second housing part, thereby penetrating through the first housing part and the second housing part in a manner of separating by a certain distance; a first slit part which is communicated with the plurality of through part and forms a supporting surface at the first housing part side, is sparated from the supporting surface and correspondingly forms a downward pressurizing surface at the second housing part side; and a first sensor unit of which one side is fixedly connected with the first housing part, and the other side is connected with the second housing part, wherein the other side integrally flows according to flowing of the second housing part.

Description

technical field [0001] The present invention relates to a load cell, and in more detail, to a case including a case having a load pressurizing portion for placing an object to be measured, and a sensor unit provided on one side of the case and set with a maximum load value, Accordingly, the load cell is measured by the sensor unit based on the load of the object pressurized by the load pressurization unit. Background technique [0002] Generally, a load cell is a device for measuring weight, and is a so-called load-power converter that outputs an electrical signal proportional to a load. [0003] Currently the most widely used weighing method is the method using a resistance wire torsion meter. The method is to extract the resistance change of the deformed elastic body due to the load on the torsion meter with an electric signal through a bridge circuit. [0004] As an example, simply refer to the load cell of the prior art, which is a load cell for weighing an object, and...
