As shown in fig. 2 to 7, the present invention discloses a U-shaped plate for a weighing module, wherein the U-shaped plate 10 is formed by bending a flat metal plate into an inverted U-shaped structure, and the width of the lower part of the U-shaped plate 10 is greater than the width of the upper part thereof. Since the middle portion of the U-shaped plate 10 needs to be provided with a sensor, an opening 11 is opened on one side surface of the U-shaped plate 10, and the opening 11 extends from the bottom end of one side surface 12 of the U-shaped plate 10 to the upper portion of the other side surface 13 to be provided with a sensor.

For the convenience of sensor placement and removal operations, or for providing more operation space, the inside of the opening 11 is provided with a plurality of irregular notches 14. Further, the shaped notches 14 are symmetrically distributed inside the opening 11.

In order to make the weighing module have horizontal limiting function and overturn-preventing function, the upper end surface of the U-shaped plate 10 is provided with a limiting hole 15. The upper end face of the U-shaped plate 10 is preferably planar here.

Although the front area of the flat plate is provided with the middle opening, the partial tail area on the flat plate is still continuous and the tail part is transited by a large fillet in order to maintain the structural continuity. Usually, the module is connected to a horizontal pull rod, so that at least two connecting holes 16 are formed on two side surfaces of the U-shaped plate 10, and the connecting holes 16 should be as close to the outer side edge of the U-shaped plate 10 as possible, so as to increase the length of the pull rod as much as possible and improve the metering accuracy.

Preferably, the opening 11 is provided in the middle area of the U-shaped plate 10. The width of the opening 11 is preferably one third of the length of the U-shaped plate 10, i.e. the width of the opening 11 corresponds to the width of the U-shaped plate on both sides. Of course, this is merely an example, and the width of the opening 11 may be matched to the sensor.

The whole U-shaped plate 10 is rectangular, has a narrow side and a wide side, and has a section of plane at the narrow side, the width of the plane is not less than the inner diameter of the limiting hole, and the section of plane is used for the safe falling protection in the vertical direction of the module.

In addition, since the U-shaped plate has a larger opening size on the wide side and interferes with the module mounting screws, in order to provide sufficient operating space for the mounting screws and further improve the mechanical properties of the U-shaped plate, the U-shaped plate 10 is preferably provided with concave structures 17 at the four corners. The angle between the concave structure 17 and the vertical direction is 8-10 degrees. This angle provides on the one hand sufficient space for the mounting screws and on the other hand a maximum increase in strength for the U-shaped plate.

Preferably, the female structure 17 is half the height of the U-shaped plate 10 in the height direction. Design on the one hand like this can bring tensile, compressive property to promote in vertical direction, if the indent region is too high then vertical strength descends on the contrary, crosses low then the performance promotion limited. On the other hand, the concave area should not be too high, so that the peripheral area of the connecting hole must be ensured to be a plane, and the requirement on the installation reliability of the connecting mechanism of the pull rod can be met. Moreover, the installation area of other accessories is just positioned at the maximum of the inner area of the U-shaped plate through the forming angle of the U-shaped plate.
