[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0023] See also Figures 1 to 5 The high-stability platform scale includes a scale body 1, a weighing platform 3, a weighing sensor 2, a level 4 and a multifunctional supporting foot 5.

[0024] The scale body 1 is the main structure of the high-stability platform scale, and includes at least a rectangular base for carrying a weighing sensor 2 and a weighing platform 3, and the weighing platform 3 is placed on the weighing sensor 2. When the object to be measured is placed on the weighing platform 3, the weighing sensor 2 can obtain the weight information of the object to be measured. Furthermore, in order to facilitate the use of the platform scale, the scale body 1 also includes a column, a push rod and a control panel. The lower end of the column is fixedly connected to one side of the base, the upper end is connected to the control panel, and the push rod is connected to the middle and upper part of the column to facilitate the user to push the high-stability platform scale. The control panel is electrically connected to the weighing sensor 2, and the measured data can be displayed on the control panel. These are common structures of electronic platform scales, and their working principles and connection methods are all prior art, which are well known to those skilled in the art and will not be elaborated here.

[0025] There are two levels 4, which are respectively arranged on two adjacent sides of the rectangular base. The level is a common measuring tool for measuring small angles. In the machinery industry and instrument manufacturing, it is used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the guide rails of machine tool equipment, the horizontal position and vertical position of the equipment installation, etc. In this embodiment, a common bubble level is used. When the bubbles of the two levels 4 are in the middle position, it indicates that the base of the scale body 1 is horizontal, and then the weighing platform 3 on it is also horizontal.

[0026] At least two installation grooves are respectively provided on two opposite sides of the base of the scale body 1, and the multifunctional supporting feet 5 are installed in the installation grooves one by one. Each multifunctional supporting foot includes a rotating part 51, a supporting column 52, a roller 53, a supporting head 54, a first fastening device 55 and a second fastening device 56.

[0027] A portion of the rotating portion 51 is embedded in the mounting groove and is rotatably connected to the mounting groove. The rotating portion 51 is in the shape of a disk with a portion cut off, forming an arc surface and a flat surface, wherein the flat surface extends outside the mounting groove.

[0028] The support column 52 is arranged close to the flat surface of the rotating part 51, and a roller 53 is connected to one end of the support column 52 to facilitate the movement of the high-stability platform scale. A first threaded hole is provided at the other end of the support column 52, and the support head 54 includes a spherical head and a first threaded rod, one end of the first threaded rod is fixedly connected to the head, and the other end is meshed with the first threaded hole. By rotating the first threaded rod, the distance of the head relative to the support column 52 can be changed.

[0029] The first fastening device 55 is used to limit the free rotation of the rotating part 51 relative to the installation groove. The first fastening device 55 includes an abutment joint and a second threaded rod. A second threaded hole is provided on the base of the scale body 1. One end of the second threaded hole is connected to the installation groove, and the other end is connected to the upper surface of the base. The second threaded rod passes through the second threaded hole and is meshed with the second threaded hole. The abutment joint is arranged between the rotating part 1 and the installation groove and is connected to the second threaded rod. The second threaded rod can drive the abutment joint to abut against the arc surface.

[0030] Furthermore, in order to prevent the abutment head from slipping when pressing the arc surface, saw teeth that mesh with each other are respectively provided on the contact surfaces where the abutment head and the arc surface contact each other. And because the rotating part 51 is prone to counterclockwise rotation as shown in the figure, it is preferred to design the saw teeth in a shape such as Figure 5 As shown, when the rotating part 51 tends to rotate counterclockwise, the mutually meshing saw teeth have a plane perpendicular to the tangential direction against the rotating part 1, thereby avoiding slippage and ensuring the braking effect of the first fastening device 55.

[0031] The second fastening device 56 is used to limit the free rotation of the support column 52 relative to the rotating part 51. The second abutment portion includes a third threaded rod and a clamping nut. A connecting through hole is provided on the support column 52. One end of the third threaded rod is fixedly connected to the flat surface, and the other end passes through the connecting through hole and is engaged with the clamping nut. The clamping nut can clamp the support column 52 to the flat surface to ensure that the support column 52 does not rotate relative to the flat surface.

[0032] When it is necessary to move the high-stability platform scale, rotate the support column 52 so that the roller 53 is located at the lower end, and then push the high-stability platform scale to move conveniently. When weighing, if the bottom surface of the weighing place is flat, directly rotate the support column 52 180° so that the support head 54 is located at the lower end. Each support head 54 supports the scale body 1 for weighing. When the ground at the weighing place is uneven, rotate the rotating part 51 and the support column 52 to an appropriate angle, and fix the rotating part 51 and the support column 52 with the first fastening device 55 and the second fastening device 56, and then rotate the support head 54 so that the support head 54 extends an appropriate distance relative to the support column 52, and can smoothly extend into the pit to press against the bottom of the pit, so that the platform scale is stable during weighing. When adjusting the rotating part 51, the support column 52 and the support head 53, it is also necessary to constantly observe the level 4 and make adaptive adjustments according to the displayed value of the level 4, so that the base of the scale body 1 is in a horizontal state, thereby ensuring that the weighing platform 3 above is also in a horizontal state. After adjustment, the object to be measured only needs to be placed on the weighing table 3 for weighing.

[0033] The implementation of the embodiments of the present invention has the following beneficial effects: rollers and support heads are respectively provided at both ends of the support column of the high-stability platform scale, the rollers facilitate the movement of the platform scale, and the support heads are used to stabilize the platform scale during measurement; when the ground is uneven, the rotating part can be rotated to tilt the support column to adapt to the irregular contact surface, and at the same time the support head can be adjusted to make the scale body level, and then locked and fixed by the first fastening device and the second fastening device, so that the platform scale can also keep the scale body stable and level on the uneven ground, thereby obtaining good weighing accuracy.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
