[0001] This utility model relates to the field of electronic platform scale technology, and in particular to an ultra-low platform scale that can be lifted at multiple angles. Background Technology

[0002] A platform scale is a weighing device widely used in industries such as food and pharmaceuticals. It mainly consists of a base frame, weighing platform, ramp, sensor assembly, junction box, shielded signal cable, and display instrument. To shorten ramp length, reduce operating time, improve work efficiency, and facilitate cleaning and environmental protection, a type of liftable ultra-low platform scale is commonly used on the market.

On the other hand, there is also the risk of tipping over; (2) The structural design is relatively complex, resulting in a heavy overall weight and high manufacturing cost; (3) The installation and removal of the ramp is relatively complicated and not convenient for subsequent lifting.

[0006] Furthermore, the maximum angle at which the base frame can be lifted is 75°.

[0007] Furthermore, the base frame also includes side frames, a right connecting rod, a left connecting rod, a base plate, and a reinforcing plate; there are two side frames, which are arranged opposite each other on the front and rear sides of the weighing platform; the corner plate is installed on the left end of the side frame, and the reinforcing plate is installed on the right side of the side frame; the front and rear ends of the right connecting rod are respectively connected to the right ends of the two side frames; the front and rear ends of the left connecting rod are respectively connected to the lower left ends of the two corner plates; the base plate is respectively located at the connection between the side frame and the right connecting rod and at the connection between the corner plate and the left connecting rod.

[0008] Furthermore, the weighing platform includes a platform and a sensor assembly; the platform is positioned above the base frame, and each of the four corners of the bottom end of the platform has a receiving cavity, the sensor assembly is positioned within the receiving cavity, and the platform is connected to the base frame through the sensor assembly.

[0009] Furthermore, the sensor assembly includes a load cell, a pressure head, and a rocker column; the top of the load cell is connected to the platform, and an upper groove is formed on the bottom surface of one end of the load cell; the bottom end of the pressure head is connected to the base frame, and a lower groove is formed on the top end of the pressure head; the top end of the rocker column extends into the upper groove, and its bottom end extends into the lower groove.

[0010] Furthermore, the lifting assembly includes a base and a lifting member; the left end of the base is rotatably connected to the lower left corner of the corner plate, and its right end is hinged to the right end of the lifting member; the driving end of the lifting member is hinged to the top center of the corner plate, and the safety lock is installed on the left end of the base.

[0011] Furthermore, the weighing platform also includes a limiting component for limiting the weighing platform.

Detailed Implementation

[0030] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] Example 1

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, a multi-angle liftable ultra-low platform scale includes a base frame 100, a weighing platform 200 mounted on the base frame 100, liftable components 300 respectively disposed on the front and rear sides of the base frame 100, and a safety lock 400 installed on the left end of the liftable components 300. The base frame 100 includes a corner plate 110, the lower left corner of which is rotatably connected to the left end of the liftable components 300, and the middle of its top end is connected to the drive end of the liftable components 300. The lower left part of the corner plate 110 is provided with a plurality of safety holes 111, which are arranged circumferentially along the rotatable connection between the corner plate 110 and the liftable components 300. The safety lock 400 is inserted into one of the safety holes 111.

[0033] By opening several safety holes 111 in the lower left part of the corner plate 110, and arranging the safety holes 111 around the circumference of the rotational connection between the corner plate 110 and the lifting assembly 300, the base frame 100 has multiple lifting angles. Compared with the existing platform scale, this expands the lifting angle range and reduces the impact of space limitations.

[0034] Specifically, there are three safety holes 111. The angle between the uppermost safety hole 111 and the middle safety hole 111 is 55°, and the angle between the uppermost safety hole 111 and the lowermost safety hole 111 is 75°. That is, the maximum angle at which the base frame 100 can be lifted is 75°, thereby avoiding the risk of tipping over. The safety lock 400 is existing technology and can be a pin or the like, to achieve positioning of the base frame 100 after it is lifted.

[0035] The 55° lifting angle is an intermediate setting between the initial position (0°) and the maximum angle (75°), providing flexible lifting options while ensuring most cleaning is completed, thus shortening the lifting / resetting time. In space-constrained situations, a slight lift is sufficient to expose the dust accumulation area beneath the weighing platform 200. Furthermore, the thrust required by the lifting assembly 300 at a 55° angle is significantly lower than at 75°, reducing power consumption. Additionally, the 55° lifting angle serves as a safe transition setting, preventing abrupt angle changes from 0° to 75°. Combined with the safety lock 400 inserted into the safety hole 111, it physically locks the lower angle, preventing accidental slippage. Because the 55° lifting angle reduces the wobbling of the weighing platform 200, it prevents the rocker column 223 within the receiving cavity 211 from dislodging from the groove (see below).

[0036] like Figure 1 and Figure 4 As shown, the base frame 100 also includes side frames 120, a right connecting rod 130, a left connecting rod 140, a base plate 150, and a reinforcing plate 160. There are two side frames 120, positioned opposite each other on the front and rear sides of the weighing platform 200. Angle plates 110 are installed at the left end of the side frames 120, and the reinforcing plate 160 is installed at the right side of the side frames 120. The front and rear ends of the right connecting rod 130 are connected to the right ends of the two side frames 120, respectively. The front and rear ends of the left connecting rod 140 are connected to the lower left ends of the two angle plates 110, respectively. The base plate 150 is located at the connection points between the side frames 120 and the right connecting rod 130, and at the connection points between the angle plates 110 and the left connecting rod 140. Specifically, the base plate 150 is L-shaped.

[0037] The base frame 100 is composed of corner plate 110, side frame 120, right connecting rod 130, left connecting rod 140, base plate 150 and reinforcing plate 160. While ensuring the overall strength and rigidity of the base frame 100, the structural design is simplified, thereby reducing the overall weight and manufacturing cost.

[0038] like Figure 1 , Figure 3 and Figure 5 As shown, the weighing platform 200 includes a platform 210 and a sensor assembly 220. The platform 210 is located above the base frame 100. The four corners of the bottom end of the platform 210 are respectively provided with accommodating cavities 211. The sensor assembly 220 is located in the accommodating cavity 211 to fully protect the sensor assembly 220. The platform 210 is connected to the base frame 100 through the sensor assembly 220.

[0039] like Figure 3 and Figure 4 As shown, the sensor assembly 220 includes a load cell 221, a pressure head 222, and a rocker arm 223. The top of the load cell 221 is connected to the platform 210, and an upper groove is formed on the bottom surface of one end of the load cell 221. The bottom end of the pressure head 222 is connected to the base frame 100, and a lower groove is formed on the top of the pressure head 222. The top of the rocker arm 223 extends into the upper groove, and its bottom end extends into the lower groove. Specifically, an insertion hole is formed in the middle of the base plate 150, and the bottom end of the pressure head 222 is inserted into the insertion hole. A guide surface is formed on the bottom end of the pressure head 222 to facilitate the bottom end of the pressure head 222 entering the insertion hole.

[0040] like Figure 2 and Figure 4 As shown, the weighing platform 200 also includes a limiting component 230 for limiting the weighing platform 200. The limiting component 230 is respectively disposed on the corner plate 110 and the reinforcing plate 160. The end of the limiting component 230 away from the lifting component 300 is connected to the weighing platform 200.

[0041] By setting the limiting component 230, the range of motion of the platform 210 relative to the base frame 100 is limited without affecting the weighing of the sensor component 220, thereby avoiding contact or collision between the platform 210 and the base frame 100.

[0042] like Figures 2-4 As shown, the limiting assembly 230 includes a limiting bolt 231 and a limiting nut 232; through holes are respectively provided on the corner plate 110 and the reinforcing plate 160, the limiting bolt 231 passes through the through hole and is clearance-fitted with the through hole; the end of the limiting bolt 231 away from the lifting assembly 300 extends through the table surface 210 into the receiving cavity 211, and the limiting nut 232 is installed on the end of the limiting bolt 231 away from the lifting assembly 300.

[0043] The clearance fit between the limit bolt 231 and the through hole allows the platform 210 to move slightly up and down, avoiding vertical interference and thus ensuring weighing accuracy.

[0044] like Figure 1 and Figure 2 As shown, the lifting assembly 300 includes a base 310 and a lifting member 320; the left end of the base 310 is rotatably connected to the lower left corner of the corner plate 110, and its right end is hinged to the right end of the lifting member 320; the driving end (i.e., the left end) of the lifting member 320 is hinged to the center of the top of the corner plate 110, and a safety lock 400 is installed on the left end of the base 310. Specifically, the base 310 is fixed to the foundation; the left end of the base 310 is connected to the lower left corner of the corner plate 110 via a pivot; the driving end of the lifting member 320 is connected to the center of the top of the corner plate 110 via a pivot; the lifting member 320 can be an electric push rod or a cylinder.

[0045] like Figure 1 and Figure 6 As shown, the multi-angle-lifting ultra-low platform scale also includes a ramp 500 located on the right side of the scale platform 200. A notch 510 is provided at the left end of the ramp 500, through which the right connecting rod 130 passes. Specifically, a reinforcing rib is installed in the middle of the bottom end of the ramp 500 to improve its overall strength and rigidity.

[0046] The installation of the ramp 500 is achieved by opening a notch 510 at the left end of the ramp 500 and embedding the right connecting rod 130 into the notch 510. When disassembling, the right connecting rod 130 can be disengaged from the notch 510, making the installation and disassembly of the ramp 500 convenient and facilitating subsequent lifting.

[0047] Under normal circumstances, the safety lock 400 is inserted into the uppermost safety hole 111 for limiting its position. When cleaning, environmental protection, or other needs are required, the safety lock 400 is withdrawn from the uppermost safety hole 111, and the lifting component 300 operates, driving the corner plate 110 to rotate around the rotating connection between the corner plate 110 and the lifting component 300 until it rotates to a predetermined angle. Finally, the safety lock 400 is inserted into the corresponding safety hole 111. For example, if the lifting angle is 55°, the safety lock 400 is inserted into the middle safety hole 111; if the lifting angle is 75°, the safety lock 400 is inserted into the lowermost safety hole 111.

[0048] Example 2

[0049] This embodiment further defines the safety lock 400 in Embodiment 1, such as... Figure 7 As shown, the safety lock 400 includes a housing 410, a lock cylinder 420, a mounting nut 430, a knob 440, and a spring element; the lock cylinder 420 and the spring element are disposed within the housing 410; the left end of the lock cylinder 420 abuts against the spring element, and its right end protrudes from the housing 410; the mounting nut 430 is sleeved on the housing 410, and the knob 440 is mounted on the left end of the housing 410. Specifically, the housing 410 is threaded onto the left end of the base 310; the spring element is a spring.

[0050] Under normal circumstances, the right end of the lock cylinder 420 always protrudes from the housing 410; pulling the knob 440 will retract the lock cylinder 420; if it is rotated 90° while still being pulled, it will lock in the retracted state; to unlock it, simply rotate it 90° while still being pulled; releasing the knob 440 will restore the lock cylinder 420 to the protruding state under the action of the elastic element.

[0051] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model.
