Description

Technical Field

[0001] This utility model belongs to the technical field of weighing equipment and relates to a highly stable movable scale. Background Technology

[0002] In various commercial and industrial applications, weighing equipment serves as a fundamental measurement tool, and its accuracy and reliability are crucial for ensuring fair transactions, precise control of production processes, and guaranteeing product quality. Traditional weighing solutions often rely on fixed-installation scale structures. While these devices offer advantages in stability and accuracy, they lack flexibility and are ill-suited for scenarios requiring frequent relocation or temporary setting of weighing points.

[0003] With technological advancements and changing societal needs, portable scales have emerged. Their ease of movement and relatively high accuracy have led to their widespread application in logistics, warehousing, and agricultural product procurement. In recent years, in particular, progress in electronic technology has propelled the development of electronic portable scales, enabling them to not only possess the basic functions of traditional mechanical portable scales but also to perform modern functions such as data processing, storage, and transmission, significantly improving work efficiency and management levels.

[0004] However, despite the excellent performance of electronic mobile scales in many aspects, they still face challenges in practical use. Because mobile scales need to be frequently moved to different locations for weighing operations, and in some application scenarios, ground conditions are often not ideal, with uneven surfaces, this can cause the mobile scale to tilt, thus affecting the stability and accuracy of the weighing results. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable movable scale that can automatically adjust its support during use to keep the scale level and ensure the stability and accuracy of the weighing results.

[0006] To solve the above technical problems, this utility model provides a highly stable movable scale, including a weighing base with an open top, a weighing sensor installed inside the weighing base, a support frame connected to the upper end of the weighing sensor, a weighing platform installed at the upper end of the support frame, casters installed at the four corners of the weighing base, and multiple slide rails facing outward toward the corresponding casters at the lower end of the weighing base. Each slide rail is slidably connected to a slider, and a drive motor for driving the corresponding slider is installed at one end of each slide rail. A support arm is rotatably connected to the lower end of each slide rail at the outward end, and each support arm rotates along the length of the corresponding slide rail. A connecting rod is rotatably connected between each support arm and the corresponding slider.

[0007] One end of the weighing base is provided with a connecting column pointing outward and upward. The upper end of the connecting column is provided with a display panel. The weighing base is provided with a battery and an integrated circuit board. The weighing base is provided with a level sensor for detecting its levelness. The weighing sensor, each drive motor, the display panel, the battery, and the level sensor are all electrically connected to the integrated circuit board.

[0008] By adopting the above technical solution, the mobile scale can be directly dragged and moved freely during use. When it reaches the weighing site, it first controls automatic leveling. The level sensor detects whether the weighing base is level. If it is not level, it controls four drive motors to work, driving the slider to slide. The slider slides and pushes the connecting rod to move. The moving connecting rod pulls the support arm downward to rotate, eventually making the support arm support the ground and lifting the casters off the ground. Then, fine-tuning is performed. Based on the detection results of the level sensor, the support height of different support arms is controlled to finally support the weighing base to a level position, so that stable weighing can be performed.

[0009] The present invention is further configured such that the load-bearing frame is X-shaped, and each of the four corners of the load-bearing frame is provided with a connecting hole, and the lower end of the weighing platform is provided with a plurality of insert shafts that cooperate with each connecting hole.

[0010] The present invention is further configured such that each slide rail is provided with a slide groove for sliding connection of the corresponding slider, each slide groove is rotatably connected with a threaded drive shaft, each slider is provided with a threaded hole for threaded connection with the corresponding threaded drive shaft, and one end of each drive motor is connected to one end of the corresponding threaded drive shaft.

[0011] The present invention is further configured such that each support arm of the weighing base is rotatably connected to a parallel connecting rod parallel to the corresponding slide rail at a distance away from the corresponding slide rail, and the free end of each support arm and the free end of the corresponding parallel connecting rod are respectively connected to a support plate parallel to the weighing base.

[0012] The present invention is further configured such that a battery slot is provided on one side of the weighing base, the battery is installed in the battery slot, and the battery can be pulled out of the battery slot.

[0013] The present invention is further provided that the edge of the weighing base is provided with a downward-facing protective edge.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When weighing is required, the present invention can drive the support arm to rotate downward so that the lower end of the support arm supports the ground. With the help of the level sensor, the support height of the support arm can be adjusted to adjust the weighing base to a horizontal position, ensuring that weighing is carried out in a horizontal state, ensuring the stability and accuracy of the weighing results. At the same time, the support arm supports the casters, keeping them off the ground, preventing the mobile scale from moving and causing inconvenience during use. Attached Figure Description

[0022] Example, refer to Figure 1-5A highly stable mobile scale includes a weighing base 1 with an open top. A weighing sensor 2 is installed inside the weighing base 1. A support frame 3 is connected to the upper end of the weighing sensor 2. The support frame 3 is X-shaped, and a connection hole 4 is opened at each of the four corners of the support frame 3. A weighing platform 5 is installed at the upper end of the support frame 3. Four insert shafts 6 that cooperate with each connection hole 4 are installed at the lower end of the weighing platform 5. The weight is transferred to the support frame 3 and finally detected by the weighing sensor 2 at the lower end. Four casters 7 are installed at the four corners of the weighing base 1, which enable the mobile scale to move freely. The lower end of the weighing base 1 is provided with four slide rails 8 facing outwards to the corresponding casters 7. Each slide rail 8 has a groove 9 along its length. A slider 10 is slidably connected in each groove 9. A threaded drive shaft 11 is rotatably connected in each groove 9. Each slider 10 has a threaded hole 12 that is threadedly connected to the corresponding threaded drive shaft 11. A drive motor 13 for driving the corresponding slider 10 to slide is installed at the inward end of each slide rail 8. One end of each drive motor 13 is connected to one end of the corresponding threaded drive shaft 11.

[0023] A support arm 14 is rotatably connected to the lower end of each slide rail 8 at its outward-facing end. Each support arm 14 rotates along the length of the corresponding slide rail 8. A connecting rod 15 is rotatably connected between each support arm 14 and its corresponding slider 10, allowing the slider 10 to slide and drive the connecting rod 15 to pull the support arm 14 up and down for support. A parallel connecting rod 16 is rotatably connected to each support arm 14 away from the corresponding slide rail 8. A support plate 17 parallel to the weighing base 1 is connected to the free end of each support arm 14 and the free end of the corresponding parallel connecting rod 16. The cooperation between the parallel connecting rod 16 and the support arm 14 makes the support more stable and the load-bearing capacity stronger. A protective edge 18 is provided around the edge of the weighing base 1, which is used to protect the drive motor 13, the support arm 14, and the parallel connecting rod 16.

[0024] A connecting post 19 is provided at one end of the weighing base 1, pointing outward and upward. A display panel 20 is provided at the upper end of the connecting post 19.

The weighing sensor 2, each drive motor 13, the display panel 20, the battery 22 and the level sensor 24 are all electrically connected to the integrated circuit board 23.

[0025] Working principle: During use, the mobile scale can be dragged freely. When it reaches the weighing site, it first performs automatic leveling. The level sensor 24 detects whether the weighing base 1 is level. If it is not level, it controls the four drive motors 13 to work, driving the slider 10 to slide. The slider 10 slides and pushes the connecting rod 15 to move. The moving connecting rod 15 pulls the support arm 14 and drives the horizontal connecting rod to rotate downward. Finally, the support plate 17 supports the ground downward, and the caster 7 is lifted off the ground. Then, fine-tuning is performed. According to the detection result of the level sensor 24, the support height of different support arms 14 is controlled to finally support the weighing base 1 to a level, so that stable weighing can be performed.

[0026] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated.
