Description
Technical Field
[0001] The utility model relates to the technical field of weighing platforms, in particular to an anti-twist weighing platform. Background Art
[0002] The requirements for industrial-grade scales are higher in accuracy than those for ordinary scales. Most domestic industrial scales load heavy objects directly on one or several sensors, and weigh them by collecting weighing signals through the sensors. Since the accuracy of the sensor itself decreases with the increase of the measuring range, the accuracy of the scale will also decrease with the increase of the measuring range.
[0003] At present, most of them adopt the knife bearing support method. The force of the weighed object is reduced by the lever system and then transmitted to the sensor. In this way, a sensor with a smaller range and higher accuracy can be selected for weighing, which improves the scale range and the accuracy of the scale at the same time.
[0004] However, in the prior art, the electronic scale with a lever structure is supported only by a knife bearing between the upper and lower weighing platforms, and the upper weighing platform is prone to shaking or even collapse, causing the weighing platform to be damaged or unusable. In view of this, the present application proposes an anti-twist weighing platform. Utility Model Content

[0009] Optionally, the upper weighing platform is a U-shaped structure, the number of the connecting blocks is four, and the connecting blocks are distributed at the four corners of the upper weighing platform.
[0010] By adopting the above technical solution, it is convenient to use the connecting block and the lever to transmit the force applied to the upper weighing platform to the weighing device from four directions, so as to improve the weighing accuracy.
[0011] Optionally, a plurality of mounting blocks are fixedly connected to the top of the upper weighing platform, and a tray is detachably connected to the top of the mounting block.
[0012] By adopting the above technical solution, it is convenient to fix the tray on the top of the upper weighing platform using the mounting block, so that it is convenient to place the object to be weighed on the tray
[0013] Optionally, two limiting holes are opened inside the constraint plate, and the two limiting holes are respectively located at two ends of the constraint plate, and the lower fixing column and the upper fixing column are both slidably adapted to the limiting holes.
[0014] By adopting the above technical solution, it is convenient for the lower fixing column and the upper fixing column to pass through the constraint plate using the limiting holes.
[0015] Optionally, the limiting component includes two fixing plates installed outside the constraint plate, and a tension spring installed on the fixing plate and detachably connected to the constraint plate.
[0016] By adopting the above technical solution, the tension spring can be conveniently used to limit the horizontal rotation of the fixed plate, thereby improving the restraint effect.
[0017] Optionally, the fixing plates are respectively located on the upper and lower sides of the constraint plate, the fixing plate close to the lower fixing column is located on the lower side of the constraint plate, and the fixing plate close to the upper fixing column is located on the upper side of the constraint plate.
[0018] By adopting the above technical solution, it is convenient for the two fixing plates to act on the upper and lower sides of the restraining plate, so as to improve the restraining effect.

[0020] By adopting the above technical solution, it is convenient to make the fixing flange and the fixing plate respectively fit the upper and lower sides of the restraining plate, so that the fixing plate can move in the vertical direction with the restraining plate.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] The anti-twist weighing platform is achieved by adding a constraint mechanism to an electronic scale applied to a lever structure. Since each component of the constraint mechanism is an independent individual and freely connected, its force is only in the horizontal direction and has no effect on the vertical downward force. Therefore, the device can eliminate the lateral force well without affecting the measurement accuracy of the weighing platform; it can effectively control the positions of the upper and lower weighing platforms to keep their original states during normal use and transportation, thereby achieving the effect of enhancing the practicality of the device and extending its service life.

[0032] Among them, the upper weighing platform 2 is a U-shaped structure, the number of connecting blocks 3 is four, and the connecting blocks 3 are distributed at the four corners of the upper weighing platform 2, so that the connecting blocks 3 can cooperate with the lever 5 to transmit the force exerted on the upper weighing platform 2 to the weighing device 4 from four directions, so as to improve the weighing accuracy.
[0033] Among them, the top of the upper weighing platform 2 is fixedly connected with a plurality of mounting blocks 12, and the top of the mounting block 12 is detachably connected with a tray 6, which facilitates the installation and fixation of the tray 6 through the mounting block 12, so that the object to be weighed can be placed on the tray 6 during weighing.
[0034] In this embodiment, the constraint structure includes a lower fixed column 11 fixedly installed on the lower weighing platform 1, an upper fixed column 8 fixedly installed at the bottom of the connecting block 3, a constraint plate 7 slidably installed outside the lower fixed column 11 and the upper fixed column 8, and a limiting component installed on the outside of the constraint plate 7 to reduce the shaking of the upper weighing platform 2.
[0035] Among them, two limiting holes 701 are opened inside the constraint plate 7, and the two limiting holes 701 are respectively located at the two ends of the constraint plate 7, and the lower fixed column 11 and the upper fixed column 8 are slidably adapted to the limiting holes 701, so that the lower fixed column 11 and the upper fixed column 8 can pass through the constraint plate 7 using the limiting holes 701 to realize the positioning and installation of the constraint plate 7.
