Anti-overturning support structure of stainless steel electronic scale

Abstract

This invention relates to the field of electronic scale technology and discloses an anti-tipping support structure for a stainless steel electronic scale. The structure includes a support base with an instrument box fixedly connected to its top. It also includes a weighing mechanism fixedly mounted on the top of the support base and a limiting mechanism installed on the inner wall of the weighing mechanism. When the first screw rod is loosened due to vibration, it will drive the second screw rod to rotate. Since the threads of the second screw rod and the first screw rod are opposite, when the second screw rod rotates, it will push the half-nut towards the weighing pan. When the first screw rod moves away from the weighing pan, it will also drive the drive rod, mounting rod, and spring rod to move synchronously. This will cause the two forces to counteract each other, making it difficult for the first screw rod to rotate. This keeps the first screw rod in a preset limiting position, preventing the weighing pan from tipping over. This solves the problem of frequent impacts and vibrations to the weighing pan causing excessive gaps between the second screw rod and the weighing pan, which easily leads to the weighing pan tipping over.

Description

Technical Field

[0001] This invention relates to the field of electronic scale equipment technology, specifically to an anti-tipping support structure for stainless steel electronic scales. Background Technology

[0002] Electronic scales are a type of weighing instrument that uses Hooke's Law or the lever balance principle of forces to determine the mass of an object. Electronic scales mainly consist of a load-bearing system (such as the weighing pan and scale body), a force transmission and conversion system, and an indication system. Some electronic scales measure objects through electromagnetic induction. The anti-tipping support structure is the core component that ensures the safe and stable operation of the equipment. Its core design goal is to increase the support area, lower the center of gravity height, and provide limit protection to prevent the scale body from tipping over due to off-center loading, impact, vibration, or external forces, while taking into account both weighing accuracy and structural strength.

[0003] Large electronic scales are important equipment for metrological sampling inspection. Because the objects being measured are heavy, limit bolts are usually used around the weighing platform to limit the horizontal sway of the weighing pan. There is usually a gap between the limit bolts and the weighing pan. However, each time the object being measured comes into contact with the weighing pan, it may impact the weighing pan, causing the weighing pan to vibrate. Over time, the vibration may cause the limit bolts to loosen, resulting in a larger gap between the weighing pan and the limit bolts. This can easily cause the weighing pan to tilt and affect the accuracy of weighing. Summary of the Invention

[0004] To solve the above technical problems, this invention provides an anti-tipping support structure for a stainless steel electronic scale, including a support base. An instrument box is fixedly connected to the top of the support base. The support base is made of 304 stainless steel plate and 14#b channel steel to form a square frame structure. A cross-bracing method is used to strengthen the structure. A pair of forks are provided below for easy shoveling. Triangular plates are welded to each right angle point for reinforcement to ensure the strength of the support. The structure also includes:

[0005] The weighing mechanism is fixedly mounted on the top of the support base;

[0006] The limit mechanism is installed on the inner wall of the weighing mechanism;

[0007] The locking mechanism is fixedly installed on the side wall of the weighing mechanism;

[0008] When weighing an object, the operator uses a handling device to move the object to the top of the weighing mechanism, weighs the object, and uses a limit mechanism to support the weighing mechanism from all sides.

[0009] Preferably, the weighing mechanism includes:

[0010] The component is placed on top of the support base;

[0011] The weighing assembly is fixedly mounted on the top of the support base by fasteners;

[0012] The fasteners include eight support frames that are fixedly connected to the top of the support base;

[0013] The heavy object will be moved to the top of the placement component, and its weight will be measured by the weighing component. The weight value will be displayed on the instrument panel.

[0014] Preferably, the limiting mechanism includes:

[0015] The spiral assembly is rotatably mounted on the inner wall of the support frame;

[0016] Synchronization component, which is slidably disposed on the inner wall of the support frame;

[0017] When it is necessary to adjust the gap between the spiral assembly and the placement assembly, the spiral assembly is rotated and moved toward the placement assembly, which in turn drives the synchronization assembly to move.

[0018] Preferably, the locking mechanism includes:

[0019] A connecting component is slidably disposed on the inner wall of the support frame;

[0020] The dispersion component is fixedly installed on the side wall of the support frame;

[0021] When the synchronizing component moves, it will drive the connecting component to move, so that the connecting component and the spiral component move synchronously. At the same time, when the placing component collides with the spiral component, it will also collide with the dispersing component.

[0022] Preferably, the placement component includes a weighing pan disposed on top of the support base, and four extension blocks are fixedly connected to the outer wall of the weighing pan, with the bottom of each of the four extension blocks being spherical.

[0023] The weighing pan features a circular design and is made of 304 stainless steel with a lentil-patterned steel plate. It is reinforced with 12 ribs around the center to ensure the strength of the weighing pan structure.

[0024] Preferably, the weighing assembly includes four spoke-type sensors fixedly connected to the top of the support base. The top of each of the four spoke-type sensors contacts the bottom of the four extension blocks. The spoke-type sensors are external to the weighing pan, so that they can be replaced manually without the need for a forklift during maintenance and replacement, thus enabling rapid replacement of the spoke-type sensors.

[0025] When weighing is required, the operator uses a handling device to move the heavy object to the weighing pan, causing it to fall to the top of the pan. The weighing pan will shake due to the impact of the heavy object. Once the weighing pan stabilizes, the weight of the pan will be transmitted to the spoke sensor through the extension block. The spoke sensor will then measure the weight, and the weight value will be displayed in the instrument box.

[0026] Preferably, the spiral assembly includes a spiral rod 1 threadedly connected to the inner wall of the support frame, and eight spiral rods 2 fixedly connected to the side walls of the eight spiral rods 1. The spiral direction of the eight spiral rods 1 is right-handed, and the spiral direction of the eight spiral rods 2 is left-handed.

[0027] Specifically, by rotating the first screw rod, both the first and second screw rods move towards the weighing pan, thus limiting their movement.

[0028] Preferably, the synchronization component includes drive rods slidably connected to the inner wall of the support frame, mounting rods rotatably connected to the inner walls of the eight drive rods, and the inner walls of the eight drive rods rotatably connected to the outer walls of the eight helical rods.

[0029] When the auger moves, it comes into contact with the drive rod, pushing the drive rod to move and causing the mounting rod to move. The drive rod can also rotate during the sliding process.

[0030] Preferably, the connecting assembly includes a spring rod that is slidably connected to the inner wall of the support frame, and half nuts are provided on the side walls of the eight support frames;

[0031] The side walls of the eight spring rods are slidably connected to the inner walls of the eight half nuts, and the inner walls of the eight half nuts are threadedly connected to the outer walls of the eight helical rods.

[0032] Before rotating the first screw rod, the operator pulls the spring rod to move the half nut, allowing the spring rod to accumulate rebound force and separate the half nut from the second screw rod, enabling the first screw rod to rotate smoothly. After the first screw rod moves into position, the spring rod is released to release its rebound force, allowing the half nut to contact the second screw rod. The operator then slides the half nut to adjust its position so that the internal thread of the half nut fits with the external thread of the second screw rod. When the weighing pan shakes, it will contact the second screw rod, which will block the weighing pan and reduce the shaking amplitude. When a heavy object falls on the top of the weighing pan, causing the weighing pan and support to vibrate, the vibration will be transmitted to the support frame. When the first screw rod becomes loose due to the vibration, it will rotate in the opposite direction, which will drive the second screw rod to rotate. Since the threads of the second screw rod and the first screw rod are opposite, when the second screw rod rotates, it will push the half nut towards the weighing pan until the half nut is blocked by the spring rod.

[0033] At this time, when the first screw rod moves away from the weighing pan, it will also drive the drive rod, mounting rod and spring rod to move synchronously, and will also drive the half nut away from the weighing pan. However, when the second screw rod rotates, it will push the half nut closer to the weighing pan, which will cause the two forces to counteract each other, making it difficult for the first screw rod to rotate. This keeps the first screw rod in the preset limit position, preventing the weighing pan from tipping over. This solves the problem that the weighing pan is frequently impacted and vibrates, causing the gap between the second screw rod and the weighing pan to be too large, which can easily cause the weighing pan to tip over.

[0034] Preferably, the dispersion component includes sliding sleeves fixedly connected to the side wall of the support frame, and spring-shaped rods are slidably connected to the inner walls of the eight sliding sleeves;

[0035] Each of the eight sliding sleeves has a spring ring slidably connected to its inner wall, and the side walls of the eight spring rings are fixedly connected to the side walls of the spring-shaped rods via springs.

[0036] When the weighing pan wobbles and moves towards the second screw rod, it first contacts the spring-shaped rod, pushing it to move and accumulating rebound force. The spring-shaped rod then pushes the spring ring to move, causing it to strike the support frame until the weighing pan contacts the second screw rod, limiting the pan's tilt. By first contacting the spring-shaped rod, part of the impact force is transmitted from the weighing pan to the spring ring, and then to the support frame, dispersing the impact force and reducing the impact on the second screw rod. This effectively prevents irregularly shaped objects from tipping over when falling onto the top of the weighing pan, causing significant wobbling and a strong impact on the second screw rod, which could damage both the first and second screw rods.

[0037] The present invention has the following beneficial effects:

[0038] (1) When the present invention is used, when the first screw rod is loosened due to vibration, it will rotate in the opposite direction, which will drive the second screw rod to rotate. Since the screw rod second and the screw rod first have opposite screw directions, when the screw rod second rotates, it will push the half nut to move towards the weighing pan. When the screw rod first moves away from the weighing pan, it will also drive the drive rod, the mounting rod and the spring rod to move synchronously. This will cause the two forces to counteract each other, making it difficult for the screw rod first to rotate. This will keep the screw rod first in the preset limit position, prevent the weighing pan from tipping over, and solve the problem that the weighing pan is frequently impacted and vibrates, causing the gap between the second screw rod and the weighing pan to be too large, which can easily cause the weighing pan to tip over.

[0039] (2) When it is necessary to adjust the distance between the second screw rod and the weighing pan, the operator first rotates the drive rod so that the protruding part of the drive rod faces upward, so that the drive rod separates from the first screw rod. Then, the drive rod is pushed and pulled back and forth to drive the mounting rod and the spring rod to move back and forth. When the spring rod contacts the half nut multiple times, the half nut will vibrate slightly, reducing the friction between the half nut and the second screw rod. This effectively prevents the self-locking property between the second screw rod and the half nut. When vibrating frequently, the second screw rod squeezes the half nut, which will cause the two to fit too tightly and be difficult to separate, thus facilitating the subsequent adjustment of the distance between the second screw rod and the weighing pan.

[0040] (3) When the half nut applies reverse compressive force to the spring rod, the drive rod will remain in the original position. During the process of frequent vibration causing the screw rod to loosen, the screw rod will move a small distance away from the weighing pan, so that the screw rod will squeeze the drive rod, making the two fit tightly together, increasing the friction force of the drive rod rotation, effectively preventing the drive rod from being affected by vibration and rotating, which would cause the drive rod and the screw rod to separate, affecting the limit of the screw rod.

[0041] (4) When the weighing pan moves in the direction of the second screw rod, the weighing pan will first contact the spring-shaped rod, so that part of the impact force of the weighing pan is transmitted to the spring ring through the spring-shaped rod, and then to the support frame through the spring ring, thus dispersing the impact force of the weighing pan and reducing the impact on the second screw rod. This effectively prevents the weighing of irregularly shaped objects from tipping over when the objects fall to the top of the weighing pan, causing the weighing pan to shake more and generate a stronger impact force that hits the second screw rod, which can easily damage the first and second screw rods.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1, please refer to Figures 1-4 This invention relates to an anti-tipping support structure for a stainless steel electronic scale, comprising a support base 13, an instrument box 14 fixedly connected to the top of the support base 13, and further comprising:

[0057] Weighing mechanism 1 is fixedly mounted on the top of support base 13;

[0058] Limiting mechanism 2 is installed on the inner wall of weighing mechanism 1;

[0059] The locking mechanism 3 is fixedly installed on the side wall of the weighing mechanism 1;

[0060] When weighing an object, the operator uses a handling device to move the object to the top of the weighing mechanism 1, weighs the object, and the limiting mechanism 2 provides support around the weighing mechanism 1.

[0061] Weighing mechanism 1 includes:

[0062] Placement component 11 is installed on top of support base 13;

[0063] Weighing component 12 is fixedly mounted on top of support base 13 by fasteners;

[0064] The fasteners include eight support brackets 122 that are fixedly connected to the top of the support base 13;

[0065] The heavy object is moved to the top of the placement component 11, and its weight is measured by the weighing component 12. The weight value is then displayed on the instrument box 14.

[0066] Limiting mechanism 2 includes:

[0067] The spiral assembly 21 is rotatably mounted on the inner wall of the support frame 122;

[0068] Synchronization component 22 is slidably disposed on the inner wall of support frame 122;

[0069] When it is necessary to adjust the gap between the spiral assembly 21 and the placement assembly 11, the spiral assembly 21 is rotated and moved toward the placement assembly 11, which will cause the synchronous assembly 22 to move.

[0070] Card-connecting mechanism 3 includes:

[0071] The connecting component 31 is slidably disposed on the inner wall of the support frame 122;

[0072] Dispersion component 32 is fixedly installed on the side wall of support frame 122;

[0073] When the synchronization component 22 moves, it will drive the connection component 31 to move, so that the connection component 31 and the spiral component 21 move synchronously. At the same time, when the placement component 11 hits the spiral component 21, it will also hit the dispersion component 32.

[0074] Example 2, please refer to Figures 3-10 The present invention is an anti-tipping support structure for a stainless steel electronic scale. Based on Example 1, the placement component 11 includes a scale pan 111 set on the top of the support base 13. Four extension blocks 112 are fixedly connected to the outer wall of the scale pan 111, and the bottom of the four extension blocks 112 is spherical.

[0075] The inner wall of the weighing pan 111 is equipped with multiple reinforcing ribs. The weighing pan 111 is circular in shape and made of stainless steel.

[0076] The weighing assembly 12 includes four spoke-type sensors 121 fixedly connected to the top of the support base 13. The top of each of the four spoke-type sensors 121 contacts the bottom of the four extension blocks 112. The model of the spoke-type sensors 121 is BM24R-C3-3T.

[0077] When weighing is required, the operator uses a handling device to move the heavy object to the weighing pan 111, causing the heavy object to fall to the top of the weighing pan 111. The weighing pan 111 will shake due to the impact of the heavy object. Once the weighing pan 111 is stable, the weight of the weighing pan 111 will be transmitted to the spoke sensor 121 through the extension block 112. The spoke sensor 121 will measure the weight, and the weight value will be displayed through the instrument box 14.

[0078] The spiral assembly 21 includes a spiral rod 211 threadedly connected to the inner wall of the support frame 122, and spiral rods 212 fixedly connected to the side walls of the eight spiral rods 211. The spiral direction of the eight spiral rods 211 is right-handed, the spiral direction of the eight spiral rods 212 is left-handed, and the pitch of the eight spiral rods 211 is the same as the pitch of the eight spiral rods 212.

[0079] Specifically, by rotating the first screw rod 211, the first screw rod 211 and the second screw rod 212 are moved towards the weighing pan 111, thus limiting their movement.

[0080] The synchronization component 22 includes drive rods 221 that are slidably connected to the inner wall of the support frame 122. The inner walls of the eight drive rods 221 are rotatably connected to mounting rods 222, and the inner walls of the eight drive rods 221 are rotatably connected to the outer walls of the eight helical rods 211.

[0081] When the screw rod 211 moves, it will come into contact with the drive rod 221, such as... Figure 4 As shown in the position of G, pushing the drive rod 221 to move causes the mounting rod 222 to move, and the drive rod 221 can also rotate during the sliding process.

[0082] The connecting assembly 31 includes a spring rod 312 that is slidably connected to the inner wall of the support frame 122, and a half nut 311 is provided on the side wall of each of the eight support frames 122;

[0083] The side walls of the eight spring rods 312 are slidably connected to the inner walls of the eight half nuts 311, and the inner walls of the eight half nuts 311 are threadedly connected to the outer walls of the eight spiral rods 212.

[0084] Before rotating the first screw rod 211, the operator pulls the spring rod 312 to move the half nut 311, allowing the spring rod 312 to accumulate rebound force, separating the half nut 311 from the second screw rod 212, enabling the first screw rod 211 to rotate smoothly. Once the first screw rod 211 is in position, the spring rod 312 is released, releasing its rebound force and allowing the half nut 311 to contact the second screw rod 212. The operator then slides the half nut 311, adjusting its position until its internal thread engages with the external thread of the second screw rod 212, causing the weighing pan 111 to sway. When the weight falls onto the top of the weighing pan 111, causing it and the support base 13 to vibrate, the vibration is transmitted to the support frame 122. If the screw rod 211 becomes loose due to the vibration, it will rotate in the opposite direction, causing the screw rod 212 to rotate. Since the screw rod 212 and the screw rod 211 have opposite thread directions, when the screw rod 212 rotates, it will push the half nut 311 towards the weighing pan 111 until the half nut 311 is blocked by the spring rod 312. Figure 7 The position of H in the middle is shown;

[0085] At this time, when the first screw rod 211 moves away from the weighing pan 111, it will also drive the drive rod 221, the mounting rod 222 and the spring rod 312 to move synchronously, and will also drive the half nut 311 away from the weighing pan 111. However, when the second screw rod 212 rotates, it will push the half nut 311 closer to the weighing pan 111, which will cause the two forces to resist each other, making it difficult for the first screw rod 211 to rotate. This keeps the first screw rod 211 in the preset limit position, preventing the weighing pan 111 from overturning. This solves the problem that the weighing pan 111 is frequently impacted and vibrates, causing the gap between the second screw rod 212 and the weighing pan 111 to be too large, which can easily cause the weighing pan 111 to overturn.

[0086] The dispersion component 32 includes a sliding sleeve 321 fixedly connected to the side wall of the support frame 122, and spring-shaped rods 322 are slidably connected to the inner walls of the eight sliding sleeves 321.

[0087] Each of the eight sliding sleeves 321 has a spring ring 323 slidably connected to its inner wall, and the side walls of the eight spring rings 323 are fixedly connected to the side walls of the spring-shaped rod 322 by springs.

[0088] When the weighing pan 111 wobbles and moves towards the spiral rod 212, it first contacts the spring-shaped rod 322, thus pushing the spring-shaped rod 322 to move. This allows the spring-shaped rod 322 to accumulate rebound force, which in turn pushes the spring ring 323 to move, causing the spring ring 323 to strike the support frame 122, until the weighing pan 111 contacts the spiral rod 212, thus limiting the tilt of the weighing pan 111. The initial contact between the weighing pan 111 and the spring-shaped rod 322 causes partial contact between the weighing pan 111 and the spiral rod 212. The impact force is transmitted to the spring ring 323 through the spring-shaped rod 322, and then to the support frame 122 through the spring ring 323, which disperses the impact force of the weighing pan 111 and reduces the impact on the screw rod 212. This effectively prevents the weighing pan 111 from tilting when the weighing of irregularly shaped objects falls to the top of the weighing pan 111, causing the weighing pan 111 to shake significantly and generate a strong impact force that hits the screw rod 212, which could easily damage both the screw rod 211 and the screw rod 212.

[0089] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0090] A specific application of this embodiment is as follows: When using this invention, if it is necessary to limit the perimeter of the weighing pan 111, the operator pulls the spring rod 312 to move the half nut 311, causing the spring rod 312 to accumulate rebound force, separating the half nut 311 from the second screw rod 212. Then, the first screw rod 211 is rotated, causing the first screw rod 211 to move spirally, bringing the first screw rod 211 and the second screw rod 212 closer to the weighing pan 111. When the first screw rod 211 moves, it will contact the drive rod 221, such as... Figure 4 As shown in position G, push the drive rod 221 to move, which will drive the mounting rod 222 and the spring rod 312 to move synchronously until the second spiral rod 212 moves into place. Then release the spring rod 312 to release the spring force of the spring rod 312, so that the half nut 311 contacts the second spiral rod 212. The operator then slides the half nut 311 to adjust the position of the half nut 311 so that the internal thread of the half nut 311 fits with the external thread of the second spiral rod 212.

[0091] When weighing is required, the operator uses a handling device to move the heavy object to the weighing pan 111, causing the heavy object to fall to the top of the weighing pan 111. The weighing pan 111 will shake due to the impact of the heavy object. Once the weighing pan 111 is stable, the weight of the weighing pan 111 will be transmitted to the spoke sensor 121 through the extension block 112. The weight is measured by the spoke sensor 121 and then displayed through the instrument box 14.

[0092] When the weighing pan 111 shakes, it comes into contact with the second screw rod 212. The second screw rod 212 blocks the weighing pan 111, reducing the shaking amplitude. When a heavy object falls on top of the weighing pan 111, causing the weighing pan 111 and support base 13 to vibrate, the vibration is transmitted to the support frame 122. When the first screw rod 211 becomes loose due to the vibration, it will rotate in the opposite direction, which will drive the second screw rod 212 to rotate. Since the threads of the second screw rod 212 and the first screw rod 211 are opposite, when the second screw rod 212 rotates, it will push the half nut 311 towards the weighing pan 111 until the half nut 311 is blocked by the spring rod 312. Figure 7 The position of H in the middle is shown;

[0093] At this time, when the first screw rod 211 moves away from the weighing pan 111, it will also drive the drive rod 221, the mounting rod 222 and the spring rod 312 to move synchronously, and will also drive the half nut 311 away from the weighing pan 111. However, when the second screw rod 212 rotates, it will push the half nut 311 closer to the weighing pan 111, which will cause the two forces to resist each other, making it difficult for the first screw rod 211 to rotate. This keeps the first screw rod 211 in the preset limit position, preventing the weighing pan 111 from overturning. This solves the problem that the weighing pan 111 is frequently impacted and vibrates, causing the gap between the second screw rod 212 and the weighing pan 111 to be too large, which can easily cause the weighing pan 111 to overturn.

[0094] Secondly, when it is necessary to adjust the distance between the screw rod 212 and the weighing pan 111, the operator first rotates the drive rod 221 so that the protruding part of the drive rod 221 faces upwards, such as... Figure 4 As shown in position G, the drive rod 221 is separated from the screw rod 211. Then, the drive rod 221 is pushed towards the weighing pan 111 until the spring rod 312 is blocked by the half nut 311. Then, the drive rod 221 is pulled away from the weighing pan 111, so that the spring rod 312 is blocked by the half nut 311 again. This process is repeated, causing the mounting rod 222 and the spring rod 312 to move back and forth. When the spring rod 312 contacts the half nut 311 multiple times, the half nut 311 will vibrate slightly, reducing the friction between the half nut 311 and the screw rod 212. This effectively prevents the screw rod 212 from having a self-locking property with the half nut 311. When vibrating frequently, the screw rod 212 squeezes the half nut 311, causing the two to fit too tightly and be difficult to separate, thus facilitating the subsequent adjustment of the distance between the screw rod 212 and the weighing pan 111.

[0095] When the half nut 311 is loosened, the drive rod 221 is rotated again to contact the first screw rod 211, so that when the first screw rod 211 moves, it can push the drive rod 221 to move. Then, the spring rod 312 is pulled again to separate the half nut 311 from the second screw rod 212, and the distance between the second screw rod 212 and the weighing pan 111 is adjusted.

[0096] Secondly, when the half nut 311 applies a reverse compressive force to the spring rod 312, it will keep the drive rod 221 in its original position. During the process of frequent vibration causing the screw rod 211 to loosen, the screw rod 211 will move a small distance away from the weighing pan 111, so that the screw rod 211 will squeeze the drive rod 221, making the two fit tightly together, increasing the friction of the drive rod 221 rotation, effectively preventing the drive rod 221 from being affected by vibration and rotating, which would cause the drive rod 221 to separate from the screw rod 211 and affect the limit of the screw rod 211.

[0097] Secondly, when the weighing pan 111 wobbles and moves towards the spiral rod 212, the weighing pan 111 will first contact the spring-shaped rod 322, thereby pushing the spring-shaped rod 322 to move, allowing the spring-shaped rod 322 to accumulate rebound force. The spring-shaped rod 322 will then push the spring ring 323 to move, causing the spring ring 323 to strike the support frame 122, until the weighing pan 111 contacts the spiral rod 212, limiting the tilt of the weighing pan 111. By first contacting the spring-shaped rod 322, the weighing pan 111 partially... The impact force is transmitted to the spring ring 323 through the spring-shaped rod 322, and then to the support frame 122 through the spring ring 323, which disperses the impact force of the weighing pan 111 and reduces the impact on the screw rod 212. This effectively prevents the weighing pan 111 from tilting when the weighing of irregularly shaped objects falls to the top of the weighing pan 111, causing the weighing pan 111 to shake significantly and generate a strong impact force that hits the screw rod 212, which could easily damage both the screw rod 211 and the screw rod 212.
