Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of weighing instruments, and particularly relates to a platform scale. Background Art
[0002] A platform scale is an electronic weighing instrument between a table scale and a truck scale, mainly including a weighing platform, a bottom frame, and load cells. The weighing platform is arranged directly above the bottom frame, and its four corners are respectively connected to the bottom frame through load cells.
[0003] During the leveling process of the platform scale, the common method is to pry up a corner of the bottom frame with a crowbar and then insert a gasket under it. Such leveling requires a gap between the corner of the bottom frame and the foundation. Otherwise, if the crowbar is forced into the gap between the bottom frame and the foundation, it will damage the paint on the surface of the bottom frame, affecting the appearance of the product. Seriously, it will also cause deformation of the corner of the bottom frame, affecting subsequent leveling and damaging the use performance of the scale. In addition, in order to avoid damaging deformation of the load cells under eccentric loads, the common method is to respectively set limit posts at the four corners of the bottom frame. There is a certain distance between the limit posts and the load cells. When the load cells are offset under eccentric loads, the limit posts come into contact with the load cells to achieve limiting. Such limiting not only causes the side of the load cell to be squeezed, which is not conducive to the protection of the load cell and affects the weighing accuracy, but also, in order to ensure the limiting effect, the distance between the limit posts and the load cells needs to be adjusted according to different sizes of load cells. Otherwise, the limiting effect will be affected and the versatility is poor. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a platform scale with a simple structural design, guaranteed product appearance and leveling effect, full protection of the load cells while realizing the limiting function, and strong versatility.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a platform scale, including a bottom frame, a weighing platform arranged directly above the bottom frame, and load cells connecting the corners of the bottom frame and the corners of the weighing platform. It further includes a support plate. The bottom frame includes a bottom plate arranged at the corner. The corner end of the bottom plate is provided with a cut-off corner. The support plate is installed on the top surface of the corner end of the bottom plate, and the vertical projection of the support plate covers the vertical projection of the cut-off corner.
[0006] Furthermore, it further includes a limiting assembly. The limiting assembly includes a limiting plate and a protection plate.

The top end of the shipping and loading plate extends towards the panel direction and is located above the panel.
[0013] The beneficial effects of the present utility model are as follows:
[0014] (1) In the present utility model, the cooperative setting of the cut corner and the support plate enables a gap to always exist between the support plate and the foundation.

Detailed implementation mode
[0025] Now, the present utility model will be further described with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.
[0026] Such as Figure 1 、 Figure 2 and Figure 5As shown in the figure, a platform scale includes a bottom frame 100, an upper scale 200 disposed directly above the bottom frame 100, and a weighing sensor 300 connecting the corners of the bottom frame 100 and the corners of the upper scale 200. It further includes a support plate 400. The bottom frame 100 includes a bottom plate 110 disposed at the corners. A notch 111 is formed at the corner end of the bottom plate 110. The support plate 400 is installed on the top surface of the corner end of the bottom plate 110, and the vertical projection of the support plate 400 covers the vertical projection of the notch 111. The cooperation of the notch 111 and the support plate 400 ensures that there is always a gap between the support plate 400 and the foundation. When leveling is required, a crowbar can be inserted into the notch 111 to pry the support plate 400, preventing the crowbar from forcibly piercing between the bottom frame 100 and the foundation. This does not affect the appearance of the product and will not cause deformation of the bottom frame 100, ensuring the leveling effect. Specifically, the bottom frame 100 further includes angle steels 120, and the two ends of the angle steels 120 are respectively connected to the bottom plate 110. Both the notch 111 and the support plate 400 are L-shaped, enabling prying from the two adjacent sides of a certain corner end during leveling, not limited to a specific direction, which improves the convenience of leveling. When a certain corner end of the platform scale needs to be pried up, a crowbar is inserted into the notch 111 at this corner end to pry up the support plate 400, and then a gasket is inserted under the bottom plate 110 at this corner end.
[0027] As Figure 1 , Figure 2 and Figure 4 shown in the figure, the platform scale further includes a limiting component 500. The limiting component 500 includes a limiting plate 510 and a protection plate 520. The limiting plate 510 is vertically installed on the top surface of the corner end of the bottom plate 110 and is disposed outside the weighing sensor 300. The upper scale 200 includes a panel 210. The protection plate 520 is vertically installed on the bottom surface of the corner end of the panel 210 and is disposed outside the limiting plate 510. The top surface height of the limiting plate 510 is greater than the bottom surface height of the protection plate 520, and there is a spacing D between the limiting plate 510 and the protection plate 520. The cooperation of the limiting plate 510 and the protection plate 520 enables the realization of limiting without any contact with the weighing sensor 300, fully protecting the weighing sensor 300. Moreover, the spacing D between the limiting plate 510 and the protection plate 520 is not affected by the size of the weighing sensor 300, significantly improving the versatility. Specifically, both the limiting plate 510 and the protection plate 520 are L-shaped. A plurality of cleaning holes 521 are formed on the protection plate 520 for regular cleaning and maintenance of the weighing sensor 300. When the upper scale 200 is subjected to a horizontal force, the upper scale 200, the weighing sensor 300, and the protection plate 520 move horizontally. The protection plate 520 displaces relative to the limiting plate 510, and the spacing D between the limiting plate 510 and the protection plate 520 becomes smaller until the protection plate 520 contacts the limiting plate 510 to achieve limiting.
[0028] As Figure 1 andFigure 6 As shown, the weighing scale 200 further includes a wiring channel steel 220, a reinforcing plate 230, and a lifting eye bolt 240. The wiring channel steel 220 is respectively installed on the four sides of the bottom surface of the panel 210. The reinforcing plate 230 is installed on the bottom surface of the corner end of the panel 210 and is connected to the end of the wiring channel steel 220. The load cell 300 is arranged in the area enclosed by the reinforcing plate 230 and the protection plate 520. The lifting eye bolt 240 is installed on the panel 210. Specifically, a junction box is arranged in one of the wiring channel steels 220; a wire passing hole is opened in the middle of the reinforcing plate 230 for the cable to pass through; the lifting eye bolt 240 is threadedly connected to the panel 210, which is convenient for installation and disassembly.
[0029] As Figure 5 and Figure 7 shown, the load cell 300 includes a pressure head 310, a sensor 320, a rocker column 330, and a dust-proof ring 340. The pressure head 310 is installed at the top end of the bottom plate 110 and is located inside the limit plate 510. The sensor 320 is installed on the bottom surface of the corner end of the panel 210. The bottom end of the rocker column 330 extends into the first installation groove 311 opened at the top of the pressure head 310, and its top end extends into the second installation groove 321 opened at the free end of the sensor 320. The dust-proof ring 340 is arranged between the pressure head 310 and the sensor 320 and is sleeved on the rocker column 330. Specifically, the sensor 320 is connected to the panel 210 through a mounting plate 350. The setting of the dust-proof ring 340 prevents dust from entering the first installation groove 311 and the second installation groove 321, ensuring the force transmission performance of the rocker column 330.
[0030] As Figure 1 and Figure 3 shown, the platform scale further includes a shipping component 600. The shipping component 600 includes a shipping plate 610, a bolt 620, and a flat washer 630. A waist-shaped hole 611 is opened at the bottom of the shipping plate 610. The bolt 620 passes through the waist-shaped hole 611 and is threadedly connected to the angle steel 120. The flat washer 630 is sleeved on the bolt 620 and is pressed against the bottom of the shipping plate 610 by the nut of the bolt 620. The top end of the shipping plate 610 extends towards the panel 210 and is located above the panel 210. Specifically, the shipping component 600 is arranged in a mirror image on both sides of the platform scale; the shipping plate 610 is in a 7-shaped configuration. The shipping component 600 limits the weighing scale 200 during transportation to avoid shaking. The opening of the waist-shaped hole 611 enables the height of the shipping plate 610 to be adjustable, thereby improving the practicability of the shipping component 600.
