DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. The present utility model is described in detail using structural schematic diagrams, etc. The schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein.

[0024] Please refer to Figures 1 to 5 , a portable electronic platform scale, which includes a base 1 and a weighing platform 2 above it. A resistive strain type weighing sensor 3 is connected between the two. When the item to be measured is placed on the weighing platform 2, due to the action of gravity, the weighing platform 2 will receive a downward pressure. This pressure will cause the electronic strain element to deform, thereby changing its resistance value. This change in resistance value is then converted into an electrical signal. After a series of processes, the weight of the item to be measured is finally displayed on the display screen. Specifically, grid-shaped reinforcing vertical ribs 1a are provided in the base 1, and feet 1b are provided at the bottom of the vertical ribs. A reinforcing plate is connected above the grid-shaped reinforcing vertical ribs 1a, and the weighing sensor 3 is connected above the reinforcing plate.

[0025] A protection platform 4 with variable height is provided on the weighing platform 2. A display 6 that can be flipped up and down is provided inside the protection platform 4. Specifically, downward-extending side guard plates 4b are provided around the protection platform 4, and a flat guard plate 4a is in the middle. The rectangular ring-shaped inner periphery surrounded by the side guard plates 4b is larger than the outer periphery of the base 1. The thickness of the flat guard plate 4a is greater than that of the display 6. A vertically penetrating hole for accommodating the display 6 is provided in the middle of the flat guard plate 4a. The display 6 is connected to the protection platform 4 through a rotating shaft 6a. Both the display 6 and the weighing sensor 3 are electrically connected to the main board inside the platform scale. The angle of the display 6 can be inclined based on the rotating shaft 6a, which is convenient for reading. It can be adjusted to face forward or backward upward.

[0026] To achieve the lifting control of the protection platform 4, the base 1 and the protection platform 4 are connected through a scissor lifting mechanism 5. The scissor lifting mechanism 5 includes a first inclined rod 5a and a second inclined rod 5b that are hinged to each other. The bottom of the first inclined rod 5a is connected to the base 1 through a fixed shaft 5c, and the bottom of the second inclined rod 5b is connected to the base 1 through a movable shaft 5d. A thread is provided in the movable shaft 5d and is engaged with a lead screw 5e in a penetrating manner. The lead screw 5e is driven to rotate by a motor 5f. The movable shaft 5d translates horizontally in a long groove provided on its outer periphery. When the motor 5f rotates, it drives the movable shaft 5d to translate, and finally the scissor mechanism 5 drives the protection platform 4 to lift. When the protection platform 4 descends, the scissor lifting mechanism 5 folds and contracts on the side of the weighing platform 2, with the back of the display 6 facing upward to protect the display screen. The protection platform 4 fits against the weighing platform 2 or has a small gap, greatly reducing the occupied space of the electronic platform scale and effectively improving its portability.

[0027] When using a portable electronic platform scale of the present utility model, place the base 1 on a supporting object, adjust the weighing platform 2 to be level by extending or shortening the supporting feet 1b to avoid measurement errors caused by tilting or shaking. When weighing, drive the motor 5f to rotate to control the lifting of the protection platform 4 to the required height. Based on the rotating shaft 6a, the inclination angle of the display 6 can be adjusted to facilitate reading. When the electronic platform scale needs to be folded for transportation, flip the display 6 so that its back is facing up and the display surface is facing down, and lower the protection platform 4, which greatly reduces the occupied space of the electronic platform scale and can well protect both the weighing platform 2 and the display 6.

[0028] As described above, the above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, any implementation changes, modifications or additions should fall within the protection scope of the present utility model.
