[0025] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides an adjustable scale foot assembly, which is applied to an electronic scale. The scale foot assembly 1 includes a nut 11 fixed to the lower surface of a scale body 2 and a bolt 12 screwed upwardly into the nut 11, and an adjustment knob 13 is sleeved on the outer side of the head of the bolt 12. The adjustment knob 33 can significantly increase the operating contact area of ​​the head of the bolt 12, greatly increasing the convenience and flexibility of operation.

[0026] In some possible implementations, the scale foot assembly 1 further includes a distance sensor 14 and a level tester 15 disposed on the scale body 2. Compared with the prior art which relies only on feeling and experience to control the adjustment distance, the distance sensor 14 of the embodiment of the present application can accurately sense the slight change of the adjustment distance, and is equipped with the level tester 15 to test and feedback the levelness in real time, thereby greatly improving the convenience of operation and the accuracy of the detection result.

[0027] In some possible implementations, the distance sensor 15 further includes a signal feedback terminal 16 disposed on the adjusting knob 13. By providing the signal feedback terminal 16 on the adjusting knob 13, the test result can be most intuitive and accurate.

[0028] In some possible implementations, the level tester 15 is disposed on the side of the scale body 2, which does not take up space but is convenient for observation and will not be lost.

[0029] In some possible implementations, the signal feedback terminal 16 is disposed on the lower surface of the adjusting knob 13 or the bolt 12 to maximize the distance between it and the body of the distance sensor 14 and reduce the relative error.

[0030] In some possible implementations, the upper end and / or the lower end of the adjusting knob 13 is configured as an inverted truncated cone structure; and / or, an anti-slip structure 14 is provided on the side of the adjusting knob 13 .

[0031] In some possible implementations, the anti-skid structure 14 is configured as circumferentially distributed semi-cylindrical anti-skid columns. The semi-cylindrical anti-skid columns can not only effectively increase the drag coefficient and eliminate friction, but also have a good hand feel.

[0032] In some possible implementations, the slope of the truncated cone-shaped structure at the upper end is greater than the slope of the inverted truncated cone-shaped structure at the lower end, so as to obtain a better hand feel.

[0033] In some possible implementations, a scale mark corresponding to the screw-in length of the bolt 12 is also provided on the adjustment knob 13. For example, different colors can be displayed in different partitions to correspond to different screw-in length intervals. The mark here only serves as a reminder. More accurate data can be sent to the control circuit by the distance sensor 14 and then displayed on the display screen of the electronic scale.

[0034] In some possible implementations, the scale markings may also be provided on the surface and / or side of the frustum.

[0035] In some possible implementations, a mounting hole 20 is provided on the lower surface of the scale body 2, and the nut 11 is concealed in the mounting hole 20, so that the structure is compact and does not affect the appearance.

[0036] In some possible implementations, the bolt 12 is a round bolt or a hexagonal bolt.

[0037] Based on the aforementioned embodiment and its possible implementation, the embodiment of the present application further provides an electronic scale, including a scale foot provided on the lower surface of the scale body, wherein the scale foot is configured as an adjustable scale foot assembly described in the aforementioned embodiment and its possible implementation. Accordingly, the technical effects achieved by the aforementioned embodiment and its possible implementation can also be fully extended to this embodiment, and will not be described in detail.

[0038] Exemplarily, the electronic scale of the embodiment of the present application is a coffee scale.
