Detailed Description

The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are described in detail with reference to the accompanying drawings.

Referring to fig. 1, the weighing sensor disclosed in this embodiment includes a sensor body 100, a bearing ram 200 and a sensor base 300, wherein the sensor body 100 is mounted on the sensor base 300, and the bearing ram 200 is mounted at the upper end of the sensor body 100.

Referring to fig. 2-3, the sensor base 300 includes a base body 301, a first flange 302 is disposed on an outer wall of the base body 301, and a notch groove 303 capable of being used for limiting is disposed on the first flange 302.

Referring to fig. 4a to 4d, the number of the notch grooves 303 is at least two, and the notch grooves 303 are uniformly distributed on the first flange 302 along the circumference, so as to achieve a better fixing effect.

The shape of the cutaway groove 303 is one of a circular arc shape, a U shape, a square shape, or an irregular shape, and the fastener used in cooperation with the cutaway groove 303 may be a bolt, a screw, or a pin, wherein the shape of the pin matches the shape of the cutaway groove 303.

Referring to fig. 2, 3, 5 and 6, a cavity 304 is formed on the base body 301, the mounting head 101 inserted into the cavity 304 is disposed at the lower end of the sensor body 100, a diameter D1 of the mounting head 101 is smaller than a diameter D2 of the cavity 304, and a gap L is disposed between the upper end surface of the sensor base 300 and the lower end surface of the sensor body 100, so that when the load cell bears a heavy object, impact force applied to the sensor body 100 can be reduced by relative swinging between the sensor body 100 and the sensor base 300, thereby achieving a buffering effect and prolonging the service life of the load cell.

The side wall of the cavity 304 is provided with a limiting hole 305, the limiting hole 305 is a threaded hole, and the limiting hole 305 can limit the swing angle 400 between the sensor body 100 and the sensor base 300 through a mounting bolt, so that the swing angle 400 can be adjusted. It is conceivable that the mounting head 101 is provided with the recess 102, and the bolt passes through the stopper hole 305 and then contacts the recess 102, which further enhances the restriction of the sensor body 100.

Referring to fig. 7, the inner wall of the bottom of the cavity 304 is provided with a second flange 306, and the mounting head 100 is in a boss shape, so as to further limit the swing angle between the sensor body 100 and the sensor base 300.

In order to avoid the tilting of the sensor body 100 caused by the excessively large swing angle of the sensor body 100, the swing angle 400 between the sensor body 100 and the sensor base 300 is set to 0 ° to 5 °, and normally, the swing angle 400 is set to 0 ° to 3 °.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and the technical effects of the present invention can be achieved by the same means, which all belong to the protection scope of the present invention.
