[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 , the present invention provides a technical solution:

[0034] A weighing device with an automatic compensation scale system includes an electronic scale body 1, the upper end surface of the electronic scale body 1 is movably connected to a rectangular box body 2, and the four corners of the lower end surface of the box body 2 are fixedly connected to movable rods 8. The upper end surface of the electronic scale body 1 is provided with a movable cavity 9 at a position corresponding to the movable rod 8. The movable rod 8 is movably connected within the movable cavity 9, and a spring is provided between the bottom of the movable rod 8 and the movable cavity 9. The electronic scale body 1 is a type of electromagnetic balance weighing device;

[0035] The inside of the box 2 is evenly distributed with weighing plates 7, and a gap of at least three millimeters is reserved between adjacent weighing plates 7. The upper end surface of the weighing plate 7 is a horizontal surface, and the lower end surface of the weighing plate 7 is integrally provided with an arc surface 10 and a circular groove;

[0036] A rotating shaft 11 is provided between the two ends of the weighing plate 7 and the interior of the box body 2 . The rotating shaft 11 is fixed to the weighing plate 7 , and one end of the rotating shaft 11 extends to the inner wall of the box body 2 for rotational connection.

[0037] Specifically, a driving structure is provided between the left side of the box body 2 and the weighing plate 7 , and two outlets 4 are provided on the right side of the electronic scale body 1 , and the two outlets 4 are respectively distributed on the upper and lower sides of the weighing plate 7 .

[0038] Specifically, the driving structure includes a gear 12 sleeved on the rotating shaft 11, and a driving plate 13 is provided on the gear 12, the lower end face of the driving plate 13 is a tooth surface, the driving plate 13 is meshed with the gear 12, and the driving plate 13 is designed to be L-shaped, wherein one side of the driving plate 13 is designed to fit the inner wall of the box 2, and a slide rail 14 is provided between the driving plate 13 and the inside of the box 2, and the slide rail 14 is fixed to the box 2. The driving plate 13 is slidably connected to the inner wall of the box 2 through the slide rail 14, and the driving plate 13 has a built-in magnet 15.

[0039] By adopting the above technical solution, the user drives the cleaning plate 3 to move on the surface of the weighing plate 7 through the handle 5, and moves the cleaning plate 3 located on the top of the weighing plate 7 to the upper side of the driving plate 13, and fixes it to the driving plate 13 by magnetic attraction through the magnet 15. Then, the user drives the cleaning plate 3 backward through the handle 5 according to the shape of the object to be weighed. If the shape of the object is spherical or cylindrical, the user drives the cleaning plate 3 backward. At this time, the rear end of the cleaning plate 3 is displaced to the inside of the connecting groove 16. Since the cleaning plate 3 and the driving plate 13 are magnetically fixed by the magnet 15, the driving plate 13 can be synchronously displaced to the rear side. At this time, the teeth at the bottom of the driving plate 13 are engaged with the gear 12 on the rotating shaft 11 at one end of the weighing plate 7, so that the gear 12 can be further driven to rotate, driving the rotating shaft 11 to rotate, so that the weighing plate 7 connected to the rotating shaft 11 is rotated one hundred and eighty degrees, so that the arc surface 10 or the circular groove surface at the bottom of the weighing plate 7 is flipped and displaced to the upper side.

[0040] Specifically, a cleaning plate 3 is provided on the outside of the driving plate 13 and the weighing plate 7, and the cleaning plate 3 is in a U-shaped structure wrapped around the weighing plate 7, and a handle 5 is fixed to the front end face of the cleaning plate 3, and a movable groove 6 is provided at the front end face of the box body 2 corresponding to the handle 5, and one end of the handle 5 extends to the interior of the box body 2 through the movable groove 6 and is fixed to the cleaning plate 3, and cleaning cotton is fixed to the inside of the cleaning plate 3, and the cleaning cotton is consistent with the weighing plate 7, and two connecting grooves 16 are provided on the inner rear side of the box body 2 corresponding to the gear 12, and the connecting groove 16 matches the cleaning plate 3, and a magnet 2 17 is fixed in the connecting groove 16.

[0041] By adopting the above technical solution, the cleaning plate 3 located in the connecting groove 16 is magnetically fixed by the magnet 2 17, further maintaining the stability of the driving plate 13 and keeping the gear 12 and the weighing plate 7 fixed; when the weighing plate 7 is used for a long time, it is inevitable that impurities or grease will be attached to the weighing plate 7. If it is not cleaned for a long time, it will affect the accuracy of the electronic scale body 1 in weighing data of the item. Therefore, the user can use the handle 5 to cooperate with the movable groove 6 to pull the rear end of the cleaning plate 3 out of the connecting groove 16, so that the cleaning plate 3 is displaced on the upper and lower end faces of the weighing plate 7, and the impurities on the surface of the weighing plate 7 are wiped and cleaned. Most of the cleaned impurities are discharged through the outlet 4, and a part is also discharged through the cone 18.

[0042] Specifically, a frustum 18 is fixed to the upper end surface of the electronic scale body 1 located inside the box 2 , and the distance between the top of the frustum 18 and the weighing plate 7 is greater than the width of the weighing plate 7 .

[0043] By adopting the above technical solution, if there is a large amount of water stains on the surface of the item during the weighing process, it can also be discharged into the surface of the cone 18 at the bottom of the box body 2 through the gap between the adjacent weighing plates 7, and then discharged from the electronic scale body 1 under the action of the inclination angle of the cone 18.

[0044] Working principle: During operation, the user drives the cleaning plate 3 to move on the surface of the weighing plate 7 through the handle 5, and moves the cleaning plate 3 located on the top of the weighing plate 7 to the upper side of the driving plate 13, and fixes it to the driving plate 13 by magnetic attraction through the magnet 15. Then, the user drives the cleaning plate 3 backward through the handle 5 according to the shape of the object to be weighed. If the object is spherical or cylindrical, the user drives the cleaning plate 3 backward. At this time, the rear end of the cleaning plate 3 moves to the inside of the connecting groove 16. Since the cleaning plate 3 and the driving plate 13 are magnetically fixed by the magnet 15, the driving plate 13 can be synchronously moved to the rear side. At this time, the teeth at the bottom of the driving plate 13 are engaged with the gear 12 on the rotating shaft 11 at one end of the weighing plate 7, so that the gear 12 can be further driven to rotate, which brings The dynamic shaft 11 rotates, causing the weighing plate 7 connected to the shaft 11 to rotate 180 degrees, causing the arc surface 10 or the circular groove surface at the bottom of the weighing plate 7 to flip and displace upward. At this time, the cleaning plate 3 located in the connecting groove 16 is magnetically fixed by the second magnet 17, further maintaining the stability of the driving plate 13, keeping the gear 12 and the weighing plate 7 fixed. Then the user places the object to be weighed on the surface of the weighing plate 7, which can achieve a good fixing effect on the object, prevent the object from rolling and slipping, and improve the weighing data of the object. At the same time, if there is a lot of water stains on the surface of the object during the weighing process, it can also be discharged into the surface of the frustum 18 at the bottom of the box body 2 through the gap between the adjacent weighing plates 7, and then discharged from the electronic scale body 1 under the action of the inclination angle of the frustum 18;

[0045] When the weighing plate 7 is used for a long time, impurities or grease will inevitably adhere to the weighing plate 7. If it is not cleaned for a long time, it will affect the accuracy of the electronic scale body 1 in weighing data of the item. Therefore, the user can use the handle 5 to cooperate with the movable slot 6 to pull the rear end of the cleaning plate 3 out of the connecting slot 16, so that the cleaning plate 3 is displaced on the upper and lower end surfaces of the weighing plate 7, and wipe and clean the impurities on the surface of the weighing plate 7. Most of the cleaned impurities are discharged through the outlet 4, and a part is also discharged through the cone 18.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
