Description

Technical Field

[0001] This utility model relates to the field of electronic balance technology, specifically a stable platform for placing an electronic balance. Background Technology

[0002] On construction sites, electronic balances are commonly used for weighing concrete mix proportions and measuring the composition of building coatings to ensure that the quality of construction materials meets standards. Due to the complex environment of construction sites, higher requirements are placed on the placement structure of electronic balances. A stable and suitable placement structure is an important prerequisite for ensuring accurate measurement data and reliable project quality.

[0003] Currently, electronic balances are often temporarily placed on makeshift workbenches, stacked material boxes, or even on the ground at construction sites. This crude placement method has significant drawbacks: in the complex environment of a construction site, electronic balances often lack a fixed structure, making them susceptible to vibrations and even falling. Secondly, the ground at construction sites is often uneven and covered with gravel, making it difficult to ensure that the electronic balance is level using conventional placement methods. This uneven force on the sensor leads to inaccurate measurement results. Utility Model Content

[0004] The purpose of this invention is to provide a stable platform for placing an electronic balance, which can at least solve some of the defects in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stable platform for placing an electronic balance, comprising a worktable for placing the electronic balance and a base plate located below the worktable, wherein the worktable and the base plate are arranged parallel to each other; the worktable is mounted above the base plate by a support rod, and the base plate is provided with an adjustment component for adjusting the levelness of the base plate.

[0006] Furthermore, the adjustment assembly includes a plurality of threaded rods that penetrate vertically through the base plate, each threaded rod being distributed on the base plate and threadedly connected to the base plate, and each threaded rod having a support plate at its bottom.

[0007] Furthermore, the bottom of the support plate is provided with a shock-absorbing pad.

[0008] Furthermore, it also includes a clamping structure for securing the electronic balance.

[0009] Furthermore, the clamping structure includes two clamping plates arranged opposite each other, two movable plates that drive the two clamping plates closer or further apart, and a driving component for driving the two movable plates to move. The area between the two clamping plates is a clamping zone for clamping the electronic balance.

[0010] Furthermore, the drive assembly includes a connecting plate, a dual-axis motor, a lead screw, and guide rods. The connecting plate and the dual-axis motor are both located below the worktable. The output end of the dual-axis motor is fixedly connected to the lead screw, and the connecting plate is fixedly connected to the guide rods, which are located on both sides of the lead screw.

[0011] Furthermore, the workbench is provided with a sliding groove for the movement of the movable plate and the clamping plate.

[0012] Furthermore, each of the clamping plates is connected to a first fixing plate via a spring assembly, and the electronic balance is clamped between two of the first fixing plates.

[0013] Furthermore, it also includes a second fixing plate for supporting the workbench, with the support rod located between the second fixing plate and the base plate.

[0014] Furthermore, the second fixing plate is provided with a rotating hole, and the top of the support rod is provided with a turntable, which is rotatably disposed in the rotating hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using adjustment components, the level of the base plate can be adjusted, thereby calibrating the level of the worktable parallel to the base plate and ensuring that the electronic balance is in a level state for operation.

[0017] 2. A set of threaded sleeves is fixedly installed at the top of the base plate, and a threaded rod is threadedly connected to the inner wall of the sleeves. By rotating the rotating plate, the threaded rod moves up and down within the threaded sleeve. Since a support plate is fixedly installed at the bottom of the threaded rod, and a rubber shock-absorbing pad is fixedly installed at the bottom of the support plate, the up and down movement of the threaded rod will push the support plate and the rubber shock-absorbing pad to move up and down. When the worktable is placed on an uneven surface, the worktable can be leveled by adjusting the threaded rod at different positions, ensuring that the balance body is measured on a horizontal plane and improving the accuracy of the measurement results. At the same time, the rubber shock-absorbing pad has good shock absorption performance, which can absorb the vibration generated by the worktable during operation, reduce the impact of vibration on the balance body, and further ensure measurement accuracy.

[0018] 3. The dual-axis motor drives the lead screws on both sides to rotate synchronously, causing the threaded moving plate to slide along the guide rod axially, achieving symmetrical adjustment of the clamping structure and significantly improving clamping efficiency and stability. The combined design of the lead screw and guide rod constrains the degree of freedom of the moving plate during sliding, avoiding skewing or jamming, ensuring uniform distribution of clamping force, and reducing the risk of deformation of the instrument due to uneven force. The sliding cooperation between the slide and the moving plate further reduces frictional resistance, making the clamping action smoother. At the same time, the mechanical self-locking characteristic maintains the fixed state after clamping, eliminating the need for additional locking operations. The contact surface between the clamping plate and the balance body adopts dual constraints of guide rod limiting and slide guide, enhancing shock resistance and effectively suppressing the interference of external impacts or vibrations on the measurement data.

[0019] 4. A spring assembly is installed on the inner wall of the clamping plate and connected to a flexible fixing plate. The elastic deformation absorbs external vibration energy, reduces the impact of rigid contact on the balance body, and reduces data fluctuations caused by high-frequency vibration. The axial compression and rebound characteristics of the spring assembly allow the clamping force to be dynamically adjusted according to the size of the instrument, avoiding excessive pressure that could cause deformation of the body. At the same time, it ensures that instruments of different specifications can fit tightly against the surface of the fixing plate, improving compatibility.

[0020] 5. A level is fixedly installed at the top of the workbench. Operators can use the level to determine whether the workbench is level, thereby adjusting the threaded rod more accurately and improving the efficiency and accuracy of adjustment. Attached Figure Description

[0029] Please see Figures 1 to 6 This utility model provides a stable platform for placing an electronic balance, including a worktable 1 for placing the electronic balance and a base plate 16 located below the worktable 1. The worktable 1 and the base plate 16 are arranged parallel to each other. The worktable 1 is mounted above the base plate 16 by a support rod, and the base plate 16 is provided with an adjustment component for adjusting the level of the base plate 16. In this embodiment, the level of the base plate 16 can be adjusted by using the adjustment component, thereby calibrating the level of the worktable 1 parallel to the base plate 16 and ensuring that the electronic balance is in a level state for operation. The support rod can be a telescopic rod 15. Preferably, the adjustment component includes a plurality of threaded rods 19 that vertically penetrate the base plate 16. Each threaded rod 19 is distributed on the base plate 16 and is threadedly connected to the base plate 16. Each threaded rod 19 has a support plate 21 at its bottom. The adjustment can be achieved by using multiple threaded rods 19 in combination. For example, when the ground is uneven, the length of the threaded rods 19 can be adjusted, and the height of different threaded rods 19 can be used to make the base plate 16 level. Preferably, the bottom of the support plate 21 is provided with a shock-absorbing pad 22, which can be a rubber shock-absorbing pad. Specifically, a set of threaded sleeves 18 is fixedly installed at the top of the base plate 16. The inner wall of the threaded sleeves 18 is threadedly connected to a threaded rod 19. A rotating plate 20 is fixedly installed at the top of the threaded rod 19, and a support plate 21 is fixedly installed at the bottom of the threaded rod 19. A rubber shock-absorbing pad 22 is fixedly installed at the bottom of the support plate 21. By rotating the threaded rods 19, the position of the support plate 21 can be adjusted to facilitate support for the base plate 16, thereby adjusting the horizontal angle of the balance body 9 on the workbench 1.

[0030] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 6The stable platform also includes a clamping structure for fixing the electronic balance. In this embodiment, the clamping structure facilitates the fixing of the electronic balance. Preferably, the clamping structure includes two clamping plates 8 arranged opposite each other, two moving plates 7 that drive the two clamping plates 8 to move closer or further apart, and a driving assembly for driving the two moving plates 7 to move. The clamping area between the two clamping plates 8 is the clamping zone for clamping the electronic balance. The driving assembly includes a connecting plate 2, a dual-axis motor 3, a lead screw 4, and a guide rod 5. The connecting plate 2 and the dual-axis motor 3 are both located below the worktable 1. The output end of the dual-axis motor 3 is fixedly connected to the lead screw 4. The guide rod 5 is fixedly connected to the connecting plate 2, and the guide rod 5 is located on both sides of the lead screw 4. The worktable 1 is provided with a sliding groove 6 for the moving plates 7 and the clamping plates 8 to move. Each clamping plate 8 is connected to a first fixed plate 11 through a spring assembly 10, and the electronic balance is clamped between the two first fixed plates 11. Specifically, connecting plates 2 are fixedly connected to both sides of the lower surface of the workbench 1, a dual-axis motor 3 is fixedly connected to the center of the lower surface of the workbench 1, and lead screws 4 are fixedly connected to the output ends of the dual-axis motors 3. Guide rods 5 are fixedly connected to the adjacent side of the connecting plates 2. The guide rods 5 are arranged on both sides of the lead screws 4. Slide grooves 6 are opened on both sides of the upper surface of the workbench 1. Moving plates 7 are slidably connected to the inner wall of the slide grooves 6. Moving plates 7 are threaded to the outer wall of the lead screws 4 and slidably connected to the outer wall of the guide rods 5. Clamping plates 8 are fixedly connected to the upper surface of the moving plates 7. The inner wall of the clamping plates 8 clamps the balance body 9. In addition, the dual-axis motor 3 drives the lead screws 4 on both sides to rotate synchronously, causing the threaded movable plate 7 to slide axially along the guide rod 5, realizing symmetrical adjustment of the clamping structure, significantly improving clamping efficiency and stability. The combined design of the lead screw 4 and the guide rod 5 constrains the degree of freedom of the movable plate 7 during sliding, avoiding skew or jamming, ensuring uniform distribution of clamping force, and reducing the risk of deformation of the instrument due to uneven force. The sliding cooperation between the slide groove 6 and the movable plate 7 further reduces frictional resistance, making the clamping action smoother. At the same time, the mechanical self-locking characteristic maintains the fixed state after clamping, eliminating the need for additional locking operations. The contact surface between the clamping plate 8 and the balance body 9 adopts the dual constraint of the guide rod 5 for limiting and the slide groove 6 for guiding, enhancing shock resistance and effectively suppressing the interference of external impacts or vibrations on the measurement data. A spring assembly 10 is fixedly connected to the inner wall of the clamping plate 8, and a first fixed plate 11 is fixedly connected to one end of the spring assembly 10. The outer wall of the first fixed plate 11 fits against the outer wall of the balance body 9, and the first fixed plate 11 is made of flexible material.The clamping plate 8 is equipped with a spring assembly 10 connected to a flexible fixing plate via its inner wall. This spring assembly absorbs external vibration energy through elastic deformation, reducing the impact of rigid contact on the balance body 9 and minimizing data fluctuations caused by high-frequency vibrations. The axial compression and rebound characteristics of the spring assembly 10 allow the clamping force to dynamically adjust according to the instrument size, preventing excessive pressure that could cause deformation of the instrument body. Simultaneously, it ensures that instruments of different specifications can fit tightly against the surface of the fixing plate, improving adaptability. The first fixing plate 11 is made of a flexible material.

[0031] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 6 The stable platform also includes a second fixed plate 12 for supporting the workbench 1, and the support rod is located between the second fixed plate 12 and the base plate 16. The second fixed plate 12 has a rotating hole 13, and the top of the support rod has a turntable 14, which is rotatably disposed within the rotating hole 13. Specifically, the lower surface of the workbench 1 is fixedly connected to the second fixed plate 12, and the lower surface of the second fixed plate 12 has a rotating hole 13. The inner wall of the rotating hole 13 is rotatably connected to the turntable 14, which allows the workbench 1 to rotate horizontally. The lower surface of the turntable 14 is fixedly connected to a telescopic rod 15, the lower surface of the telescopic rod 15 is fixedly connected to the base plate 16, and the lower surface of the base plate 16 is fixedly connected to rollers 17, facilitating adjustment of the height and position of the workbench 1.

[0032] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 6 A level 23 is fixedly installed on the top of the workbench 1. The level 23 can be a bubble level. By observing the position of the bubble, the levelness of the workbench 1 can be known, which facilitates the leveling of the balance body 9 and makes it convenient to use the balance body 9.

[0033] Therefore, the working principle of this stable platform is as follows:

[0034] By combining the spring assembly 10 with the flexible fixing plate, the device absorbs external vibration energy through elastic deformation when clamping the measuring instrument, while simultaneously dispersing local stress through the flexible contact surface to avoid rigid impact. The roller 17 enables rapid movement and fixation of the device. During clamping, the spring assembly 10 adaptively compresses according to the instrument size, and the flexible fixing plate conforms to the surface of the machine body, forming an elastic constraint to suppress vibration transmission; the roller 17 reduces frictional resistance during movement.

[0035] The operating procedure involves moving the entire structure to the target position using rollers 17, placing the balance body 9 between clamping plates 8, and causing the spring assembly 10 to deform elastically under compression. The first fixing plate 11 tightly adheres to the surface of the balance body 9, achieving adaptive clamping. By rotating the rotating plate 20, the threaded rod 19 moves up and down within the threaded sleeve 18. Since a support plate 21 is fixedly installed at the bottom of the threaded rod 19, and a rubber shock-absorbing pad is fixedly installed at the bottom of the support plate 21, the up-and-down movement of the threaded rod 19 will push the support plate 21 and the rubber shock-absorbing pad to move up and down. When the workbench 1 is placed on an uneven surface, the threaded rod 19 can be adjusted to achieve a level position, ensuring that the balance body 9 is measured on a horizontal plane and improving the accuracy of the measurement results. Simultaneously, the rubber shock-absorbing pad has excellent shock absorption performance, absorbing the vibrations generated by the workbench 1 during operation, reducing the impact of vibrations on the balance body 9, and further ensuring measurement accuracy. In addition, a level 23 is fixedly installed on the top of the workbench 1. The operator can observe the level 23 to determine whether the workbench 1 is in a level state, thereby adjusting the threaded rod 19 more accurately and improving the efficiency and accuracy of adjustment.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
