[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] See attached Figure 1-2 An electronic balance with automatic correction function includes a balance lower shell 1. The balance lower shell 1 in the present application is specifically the lower shell of the ME series electronic balance. Leveling feet 2 are installed at the four corners of the lower end of the balance lower shell 1. By adjusting the height of the four leveling feet 2 supported by the lower shell 1, the inclination of the electronic balance with automatic correction function can be adjusted, which is used to place the balance lower shell 1 horizontally to ensure that the electronic balance with automatic correction function is placed horizontally.

[0020] In this embodiment, the upper and lower ends of the horizontal adjustment foot 2 respectively pass through the inner and outer sides of the lower shell 1 of the balance, and an automatic horizontal correction mechanism 3 is installed on the inner bottom surface of the lower shell 1 of the balance. The automatic horizontal correction mechanism 3 includes a support seat 31, two miniature inclination sensors 34 and two electric crowbars. The two electric crowbars are respectively arranged on the vertical planes where the two diagonals of the lower shell 1 of the balance are located. The support seat 31 is fixedly connected to the inner bottom surface of the lower shell 1 of the balance, and the two electric crowbars are cross-installed on the upper and lower ends of the support seat 31.

[0021] It should be added that the electric crowbar is composed of a C-shaped frame 37, two round rods 32, two cylindrical rectangular frames 33 and two micro electric push rods 36. The micro electric push rods 36 are respectively arranged below one electric crowbar, and the two round rods 32 are symmetrically fixedly installed at the two ends of the C-shaped frame 37. In the present application, the openings of the two C-shaped frames 37 are staggered and opposite to each other. The two C-shaped frames 37 are rotatably connected to the upper and lower ends of the support seat 31, and the lower ends of the four round rods 32 in the two electric crowbars are respectively arranged above the four horizontal adjustment feet 2 through a plurality of chain plates 35. The lower end of the chain plate 35 is rotatably connected to the upper end of the horizontal adjustment foot 2, and the upper end of the chain plate 35 is rotatably connected to the end of the round rod 32.

[0022] Two miniature inclination sensors 34 are respectively installed on the two side end surfaces of the two support seats 31. The two miniature inclination sensors 34 are respectively used to measure the vertical angle of the balance lower shell 1 on the vertical plane where the two electric crowbars are located. The shells in the two miniature electric push rods 36 are fixedly connected to the balance lower shell 1. The upper ends of the push rods in the two miniature electric push rods 36 are respectively connected to a round rod 32 in the two electric crowbars through two cylindrical rectangular frames 33. The round rod 32 is slidably installed in the cylindrical rectangular frame 33, and the cylindrical rectangular frame 33 is formed by four cylinders fixedly connected in a rectangular shape. The round rod 32 can rotate along the contact connection with the cylinder, and the cylindrical rectangular frame 33 and the push rod in the miniature electric push rod 36 are fixedly connected.

[0023] It is further supplemented that the two micro inclination sensors 34 are connected to the micro electric push rods 36 connected to the electric crowbar through wires, and the two micro inclination sensors 34 and the two micro electric push rods 36 are connected to an external power supply through wires.

[0024] According to the utility model, each time the electronic balance with automatic correction function is moved and changed, two micro inclination sensors 34 are used to respectively measure the vertical angles of the lower shell 1 of the balance on the vertical plane where the two electric crowbars are located, and the measurement results are transmitted to the micro electric push rod 36 connected to the electric crowbar through a wire. After the micro electric push rod 36 receives the signal of the electric crowbar tilting, the push rod in the micro electric push rod 36 is pushed up or retracted downward, thereby driving the electric crowbar to rotate at the rotation connection with the support seat 31, and the electric crowbar is leveled. During the rotation and leveling process of the electric crowbar, the ends of the two round rods 32 in the electric crowbar can drive the two horizontal adjustment feet 2 on the diagonal line to rise and fall through a plurality of chain plates 35, that is, adjust the height of the support of the four horizontal adjustment feet 2 below the lower shell 1 of the balance, and can adjust the inclination of the electronic balance with automatic correction function, so as to place the lower shell 1 of the balance horizontally and ensure that the electronic balance with automatic correction function is placed horizontally.

[0025] Simply put, each time the electronic balance with automatic correction function is moved and repositioned, two miniature inclination sensors 34 first measure the vertical angles of the two bevel lines of the lower shell 1 of the balance on the vertical plane, and then the output transmission of two miniature electric push rods 36 and two electric crowbars can automatically adjust the height of the four horizontal adjustment feet 2 under the lower shell 1 of the balance, and place the lower shell 1 horizontally. Under the real-time monitoring of the two miniature inclination sensors 34, it can be ensured that the application always remains in a horizontal state, making the user's daily weighing efficient and simple.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
