AI Technical Summary
When weighing large or multiple materials, the existing weighing equipment's buffer structure is prone to exceeding its limits, causing the impact force to be directly transmitted to the weighing sensor, resulting in damage.
A protective structure was designed, comprising a load sleeve, a buffer spring, a plug rod, a rotation limit block, a slider, and a toothed groove forming a limiting structure. The buffer spring absorbs the initial impact force and locks the slider in contact with the base when the limit is exceeded, preventing the impact force from being directly transmitted to the weighing sensor.
It effectively absorbs and disperses impact forces, extends the life of the load cell, and triggers an alarm via the pressure sensor when overloaded, preventing sensor damage and improving weighing accuracy.

Description
Technical Field
[0001] This utility model relates to the field of weighing controller technology, specifically to an intelligent weighing controller with a protective structure. Background Technology
[0002] The intelligent weighing controller is the core control unit that interfaces with weighing sensors, processes weight signals, and realizes intelligent weighing management. It generally needs to be used in conjunction with electronic scale components.
[0003] For example, Chinese Patent CN218121165U discloses a high-stability weighing display controller, belonging to the field of weighing technology. Its key technical features include a display screen and a weighing device. The display screen is electrically connected to the weighing device. A stabilizing mechanism is installed on the top of the weighing device, and a sliding rod is fixedly connected to the bottom of the display screen. A support rod is sleeved on the surface of the sliding rod, and the surface of the sliding rod is slidably connected to the support rod. The stabilizing mechanism includes four first support plates, four second support plates, two first placement plates, and two second placement plates. This solves the problem that existing weighing display controllers can weigh materials normally, but when weighing excessively large or numerous materials, support plates need to be placed on the weighing device for support. Because the surface of the weighing device is relatively smooth, this causes offset when placing the support plates for weighing, resulting in weighing errors and affecting weighing accuracy.
[0004] In the operation of traditional weighing equipment, when an object is placed in the weighing area, the instantaneous impact force generated can directly act on the weighing sensor, causing damage to the weighing sensor. Some equipment is equipped with a buffer structure, but once the actual impact force exceeds the buffer limit of the buffer structure, the excess impact force will still be directly transmitted to the weighing sensor, causing the weighing sensor to bear the peak impact. Utility Model Content
[0005] The purpose of this invention is to provide an intelligent weighing controller with a protective structure to solve the problem in the above-mentioned background technology where the actual impact force exceeds the buffer limit of the buffer structure, and the excess impact force is still directly transmitted to the weighing sensor, causing the weighing sensor to bear the peak impact.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent weighing controller with a protective structure, including a base, an intelligent controller fixedly connected to the top of one end of the base, and a load sleeve installed on the outer side of the top of the base;
[0007] The top edge and both ends of the inner side of the carrying sleeve are fixedly connected to the plug rods. The lower ends of the plug rods are rotatably connected to the two sides. The four corners of the top of the base are fixedly connected to the weighing sensors. The tops of the four weighing sensors are fixedly connected to the load-bearing plates. The load-bearing plates are provided with mounting sleeves that correspond one-to-one with the plug rods. The mounting sleeves are slidably connected to the slide bars. The lower ends of the plug rods are slidably connected to the slide bars.
[0008] Preferably, the slide bar has equally spaced toothed grooves on both sides inside, and the rotation limiting block is engaged inside the toothed grooves to form a limiting structure.
[0009] Preferably, auxiliary blocks are fixedly connected to both sides of the plug rod at equal intervals. The auxiliary blocks are located on the top of the rotation limiting block. The auxiliary blocks limit the rotation angle of the rotation limiting block to 0 degrees to 45 degrees, and the rotation limiting block rotates 45 degrees and engages inside the tooth groove.
[0010] Preferably, a return spring is fixedly connected to both sides of the slide bar, the lower end of the return spring is fixedly connected to the inner side of the mounting sleeve, and the slide bar passes through the mounting sleeve and extends between the base and the load-bearing plate.
[0011] Preferably, the top of the base is fixedly connected with a pad that corresponds one-to-one with the mounting sleeve. The pad is aligned with the lower end of the slide bar and provides support for the bottom of the tooth groove. A pressure sensor is integrated inside the pad.
[0012] Preferably, each of the four top corners of the load-bearing plate is fixedly connected with a buffer spring, and the tops of the four buffer springs are fixedly connected to the four top corners inside the load sleeve.
[0013] Preferably, the intelligent controller is provided with a digital display module and a button interaction module on the top, and speakers are provided on both sides of the button interaction module located on the top of the intelligent controller, and the speakers are electrically connected to the pad block.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This intelligent weighing controller with a protective structure absorbs the initial impact force when an object is placed by setting a buffer spring between the load sleeve and the load-bearing plate, allowing the load sleeve to sink slowly and preventing the instantaneous load from acting directly on the weighing sensor. With the help of a limiting structure consisting of a plug rod, a rotating limit block, a slide bar, and a toothed groove, when the impact force exceeds the damping threshold of the buffer spring, the rotating limit block can engage with the toothed groove to lock the plug rod and the slide bar, guiding the impact force to the base.
[0016] By cooperating with the reset spring and the mounting sleeve, the slider maintains its initial position under normal conditions. In case of overload, the slider moves down to compress the reset spring for further buffering, and finally forms a rigid support through the pad on the base to prevent excessive structural movement, so that the impact force is directly transmitted to the base rather than the load cell. Through the pressure sensor integrated in the pad and the electrical connection with the speaker, an alarm can be issued in time when an overload impact occurs, reminding the user of the abnormal situation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1: Please refer to Figures 1 to 6 The present invention provides the following technical solution:
[0026] like Figure 1 As shown, an intelligent weighing controller with a protective structure includes a base 1, an intelligent controller 2 fixedly connected to the top of one end of the base 1, and a load sleeve 3 installed on the outer side of the top of the base 1; as shown... Figure 5 and Figure 6 As shown, the top edge and both ends of the inner side of the load sleeve 3 are fixedly connected to the plug rod 4. The lower ends of the plug rod 4 are rotatably connected to the two sides of the rotation limit block 5. The four corners of the top of the base 1 are fixedly connected to the weighing sensor 7. The top of the four weighing sensors 7 are fixedly connected to the load plate 8. The load plate 8 is provided with the mounting sleeve 9 corresponding to the plug rod 4. The mounting sleeve 9 is slidably connected to the slide bar 10. The lower end of the plug rod 4 is slidably connected to the slide bar 10.
[0027] like Figure 4 As shown, the slider 10 has equally spaced toothed grooves 11 on both sides inside, and the rotation limiting block 5 is locked inside the toothed grooves 11 to form a limiting structure.
[0028] like Figure 6 As shown, auxiliary blocks 6 are fixedly connected to both sides of the plug rod 4 at equal intervals. The auxiliary blocks 6 are located on the top of the rotation limit block 5. The auxiliary blocks 6 limit the rotation angle of the rotation limit block 5 from 0 degrees to 45 degrees, and the rotation limit block 5 rotates 45 degrees and engages inside the tooth groove 11.
[0029] like Figure 3 and Figure 4 As shown, a return spring 12 is fixedly connected to both sides of the slide bar 10. The lower end of the return spring 12 is fixedly connected to the inner side of the mounting sleeve 9. The slide bar 10 passes through the mounting sleeve 9 and extends to the space between the base 1 and the load-bearing plate 8.
[0030] like Figure 2 As shown, the top of the base 1 is fixedly connected to a pad 13 corresponding to the mounting sleeve 9. The pad 13 is aligned with the lower end of the slide bar 10 and forms support for the bottom of the toothed groove 11. The pad 13 integrates a pressure sensor. The top four corners of the load-bearing plate 8 are fixedly connected to buffer springs 14. The top of the four buffer springs 14 is fixedly connected to the top four corners of the inner part of the carrying sleeve 3. The top of the intelligent controller 2 is provided with a digital display module 15 and a button interaction module 16. The button interaction module 16 is provided with speakers 17 located on the top of the intelligent controller 2 on both sides. The speakers 17 are electrically connected to the pad 13.
[0031] During normal weighing operation, when an object is placed on top of the load sleeve 3, the load sleeve 3 bears the weight of the object and is connected to the base 1 through its internal structure. The buffer spring 14 at the top of the load sleeve 3 is located between the load sleeve 3 and the load-bearing plate 8. The downward pressure applied by the object compresses the buffer spring 14, causing the load sleeve 3 to slowly sink. The intelligent controller 2 detects the data change of the weighing sensor 7 below the load-bearing plate 8, but the weighing result can only be displayed through the digital display module 15 after the load sleeve 3 moves smoothly and the data of the intelligent controller 2 stabilizes.
[0032] The load cell 7 is fixedly connected to the four corners of the top of the base 1, and the load plate 8 is fixed to the top of the load cell 7. Therefore, the load cell 7 only measures the weight of the load plate 8 and its accessories, while the buffer spring 14 absorbs the initial impact force and reduces the instantaneous load transmitted to the load cell 7.
[0033] When the load sleeve 3 is subjected to external impact, the buffer spring 14 is further compressed to absorb part of the impact energy. If the impact force is small, the elastic deformation of the buffer spring 14 can slow down the downward force and make it smoothly transmitted to the load-bearing plate 8 and the load cell 7, avoiding the load cell 7 from directly bearing the peak impact, thereby extending its service life. The plug rod 4 is located on the top edge of the inner side of the load sleeve 3, and its lower end is slidably connected to the inside of the slide bar 10 of the load-bearing plate 8. The slide bar 10 has a toothed groove 11 inside, and the two sides are fixedly connected to the return spring 12. The lower end of the return spring 12 is fixed to the inside of the mounting sleeve 9. Under normal conditions, the return spring 12 keeps the slide bar 10 in the upward position, and the rotation limit block 5 does not interfere with the toothed groove 11.
[0034] When the impact force exceeds the deceleration threshold of the buffer spring 14, the load sleeve 3 will move downward quickly, causing the plug rod 4 to slide downward along the inside of the slide bar 10. The plug rod 4 is rotatably connected to the rotation limit block 5 on both sides. During the downward movement, the rotation limit block 5 rotates due to its own inertia. The rotation angle is limited to the range of 0 degrees to 45 degrees by the auxiliary block 6. When the rotation is 45 degrees, the end of the rotation limit block 5 extends outward. When the rotation limit block 5 is engaged in the tooth groove 11 inside the slide bar 10, it forms a limiting structure with the tooth groove 11, locking the plug rod 4 in the position inside the slide bar 10. After locking, the continued downward movement of the plug rod 4 pulls the slide bar 10, and the slide bar 10 slides downward inside the mounting sleeve 9. At the same time, the return spring 12 is compressed, and the lower end of the slide bar 10 gradually extends between the base 1 and the load-bearing plate 8.
[0035] When the slide bar 10 finishes moving downwards, the bottom of the slide bar 10 aligns with the top of the pad 13 on the top of the base 1. The pad 13 acts as a rigid support to prevent further movement of the slide bar 10 and the connecting rod 4. The impact force and weight of the load sleeve 3 are directly transmitted to the base 1 through the connecting rod 4, the rotation limit block 5, the slide bar 10, and the pad 13. This ensures that the load cell 7 only bears the downward pressure of the return spring 12 rather than a direct impact, preventing damage to the load cell 7. The pad 13 integrates a pressure sensor. When the slide bar 10 contacts the pad 13 and generates pressure, the sensor is electrically connected to the speaker 17, triggering the speaker 17 to emit an alarm sound to notify the user of an overload impact.
