Description

Technical Field

[0001] This utility model application relates to the field of electronic scale protection technology, specifically to a high-precision electronic scale protection device. Background Technology

[0002] An electronic scale is a type of weighing instrument. Weighing instruments are tools that use Hooke's Law or the lever balance principle of forces to determine the mass of objects. According to their structural principles, they can be divided into three main categories: mechanical scales, electronic scales, and electromechanical scales. High-precision electronic scales are precision instruments and have certain requirements for their storage environment. When people move electronic scales, they may be bumped or knocked, which can damage the scale and affect its measurement accuracy.

[0003] Chinese Patent Publication No. CN216153813U discloses an intelligent electronic scale protection device, relating to the technical field of electronic scale protection devices. The device includes a base plate, with casters fixedly mounted on the bottom surface of the base plate. A push handle is mounted on one side of the base plate. A connecting plate is fixedly mounted on the top surface of the base plate near one side, and a threaded rod rotates inside the connecting plate. A support rod is fixedly mounted on the top surface of the base plate near the other side. Placement plates a are mounted on the top of both the threaded rod and the support rod. In practical use, the combination of the base plate, casters, push handle, threaded rod, support rod, placement plate a, baffle, movable plate a, movable plate b, magnet a, magnet b, and connecting plate facilitates the handling of large quantities of electronic scales. Simultaneously, the baffle, movable plate a, and movable plate b protect the electronic scales, preventing them from being bumped or damaged during handling, reducing unnecessary economic losses, and improving practicality.

[0004] The aforementioned device protects the electronic scale from falling during transportation by using a protective device. However, when the electronic scale weighs items, it can only weigh flat items. When protecting round items, these items will slide around, making it impossible to effectively protect them. Utility Model Content

[0005] To address the aforementioned issues, a high-precision electronic scale protection device is provided. By rotating a rotating plate, it is made perpendicular to the mounting plate. Then, rotating an adjusting screw drives a threaded block to move. As the threaded block moves, it presses against one end of a connecting block. Under this pressure, the other end of the connecting block moves an L-shaped block, which in turn moves a rack. The rack, in conjunction with the gears, drives a rotating rod to rotate. Simultaneously, the protective frame outside the rotating rod also rotates. When the protective frame rotates to be perpendicular to the mounting plate, the adjusting screw is stopped. The vertical rotating plate and protective frame can protect irregularly shaped items, preventing them from slipping during weighing.

[0006] To address the problems in the existing technology, this utility model application provides a high-precision electronic scale protection device, including an electronic scale body. A mounting plate is provided on the top of the electronic scale body. Rotating plates for weighing flat items are rotatably mounted on both sides of the top of the mounting plate. Rotating rods are rotatably mounted on both sides inside the mounting plate. A gear is provided at one end of each rotating rod. A protective frame for protecting irregular items is provided outside the rotating rod. An extension frame is movably mounted inside the protective frame. A positioning component for positioning the extension frame is provided outside the extension frame.

[0007] Preferably, the mounting plate is internally provided with an adjusting screw, the external thread of the adjusting screw is provided with a threaded block, both sides of the threaded block are rotatably provided with connecting blocks, one end of the connecting block is rotatably provided with an L-shaped block, and one end of the L-shaped block is provided with a rack that meshes with a gear.

[0008] Preferably, the mounting plate has a groove inside for the L-shaped block to move.

[0009] Preferably, the positioning assembly includes positioning blocks disposed on both sides of the extension frame. A pull rod is movably disposed inside the positioning block. A pressing block is disposed at one end of the pull rod. Symmetrical positioning pins are disposed on the side wall of the pressing block. A compression spring is sleeved on the outside of the pull rod. One end of the compression spring is connected to the side wall of the positioning block, and the other end of the compression spring is connected to the side wall of the pressing block. The outer wall of the protective frame is provided with a plurality of positioning holes that are adapted to the positioning pins.

[0010] Preferably, the outer wall of the protective frame is provided with a rectangular groove for the positioning block to move.

[0011] Preferably, the top of the rotating plate is provided with an anti-slip pad.

[0012] The advantages of this utility model application compared to the prior art are:

[0013] 1. By rotating the rotating plate to make it perpendicular to the mounting plate, the adjusting screw is then rotated to move the threaded block. As the threaded block moves, it presses against one end of the connecting block, and the other end of the connecting block, under pressure, moves the L-shaped block, which in turn moves the rack. The rack and pinion, working in conjunction with the gears, can drive the rotating rod to rotate. At the same time, the protective frame outside the rotating rod will also rotate. When the protective frame rotates to be perpendicular to the mounting plate, the adjusting screw is stopped. The vertical rotating plate and protective frame can protect irregular items and prevent them from slipping during weighing.

[0014] 2. By pulling the lever, the pressing block and the positioning pin are moved, so that the positioning pin is away from the positioning hole on the outer wall of the protective frame. At this time, the positioning block can be moved along the rectangular groove on the outer wall of the protective frame. At the same time, the extension frame will also move with the positioning block. When the extension frame is adjusted to a suitable height, the lever can be released. At this time, under the action of the compression spring, the positioning pin will be inserted into the corresponding positioning hole. The outward extension frame can protect tall items, improving the practicality of the device. Attached Figure Description

Detailed Implementation

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 7 As shown, this utility model application provides:

[0025] A high-precision electronic scale protection device includes an electronic scale body 1. The top of the electronic scale body 1 is provided with a mounting plate 4. Rotating plates 3 for weighing flat items are rotatably provided on both sides of the top of the mounting plate 4. Rotating rods 6 are rotatably provided on both sides inside the mounting plate 4. A gear 10 is provided at one end of the rotating rod 6. A protective frame 5 for protecting irregular items is provided outside the rotating rod 6. An extension frame 12 is movably provided inside the protective frame 5. A positioning component for positioning the extension frame 12 is provided outside the extension frame 12.

[0026] When it is necessary to weigh a flat object, simply place the object on top of the rotating plate 3. When the rotating plate 3 is rotated, the rotating rod 6 and the protective frame 5 outside the rotating rod 6 will also rotate. When the protective frame 5 rotates to be perpendicular to the mounting plate 4, stop rotating the adjusting screw 2. The vertical rotating plate 3 and the protective frame 5 can protect irregular objects and prevent these irregular objects from slipping during weighing.

[0027] like Figure 3 and Figure 4 As shown, an adjusting screw 2 is rotatably provided inside the mounting plate 4, and a threaded block 8 is provided on the external thread of the adjusting screw 2. Connecting blocks 7 are rotatably provided on both sides of the threaded block 8. An L-shaped block 9 is rotatably provided at one end of the connecting block 7, and a rack 11 that meshes with the gear 10 is provided at one end of the L-shaped block 9.

[0028] The adjusting screw 2 drives the threaded block 8 to move. When the threaded block 8 moves, it will press one end of the connecting block 7. The other end of the connecting block 7 will drive the L-shaped block 9 to move under the pressure, which in turn drives the rack 11 to move. The rack 11, in conjunction with the gear 10, can drive the rotating rod 6 to rotate.

[0029] like Figure 4 As shown, the mounting plate 4 has a sliding groove inside for the L-shaped block 9 to move.

[0030] The slide groove prevents the L-shaped block 9 from shifting position during movement, further enhancing the stability of the rack 11 during operation.

[0031] like Figure 5 and Figure 6 As shown, the positioning assembly includes positioning blocks 13 disposed on both sides of the extension frame 12. A pull rod 14 is movably disposed inside the positioning block 13. A pressing block 15 is disposed at one end of the pull rod 14. Symmetrical positioning pins 16 are disposed on the side wall of the pressing block 15. A compression spring 17 is sleeved on the outside of the pull rod 14. One end of the compression spring 17 is connected to the side wall of the positioning block 13, and the other end of the compression spring 17 is connected to the side wall of the pressing block 15. Multiple positioning holes that are adapted to the positioning pins 16 are opened on the outer wall of the protective frame 5.

[0032] By pulling the lever 14, the compression block 15 and the positioning pin 16 are moved, so that the positioning pin 16 is away from the positioning hole on the outer wall of the protective frame 5. At this time, the positioning block 13 can be moved, and the extension frame 12 will also move with the positioning block 13. When the extension frame 12 is adjusted to a suitable height, the lever 14 can be released. At this time, under the action of the compression spring 17, the positioning pin 16 will be inserted into the corresponding positioning hole. The extension frame 12 extending outward can protect tall items, improving the practicality of the device.

[0033] like Figure 5 As shown, the outer wall of the protective frame 5 has a rectangular groove for the positioning block 13 to move.

[0034] The rectangular slot makes the positioning block 13 more stable when it moves.

[0035] like Figure 1 As shown, the top of the rotating plate 3 is provided with an anti-slip pad.

[0036] The anti-slip pad on top of the rotating plate 3 can ensure the stability of the item during weighing.

[0037] Working principle: When weighing flat items, simply place the item on top of the rotating plate 3. The anti-slip pad on top of the rotating plate 3 ensures the stability of the item during weighing. When weighing irregular or round items, first rotate the rotating plate 3 until it is perpendicular to the mounting plate 4. Then, rotate the adjusting screw 2 to move the threaded block 8. As the threaded block 8 moves, it presses against one end of the connecting block 7. The other end of the connecting block 7, under pressure, moves the L-shaped block 9, further moving the rack 11. The rack 11, in conjunction with the gear 10, rotates the rotating rod 6. Simultaneously, the protective frame 5 outside the rotating rod 6 also rotates. The rotation stops when the protective frame 5 is perpendicular to the mounting plate 4. Rotating the adjusting screw 2 allows for the protection of irregularly shaped items by utilizing the vertical rotating plate 3 and the protective frame 5, preventing these items from slipping during weighing. When the height of the protective frame 5 needs to be adjusted, pulling the lever 14 moves the pressing block 15 and the positioning pin 16, causing the positioning pin 16 to move away from the positioning hole on the outer wall of the protective frame 5. At this time, the positioning block 13 can be moved along the rectangular groove on the outer wall of the protective frame 5, and the extension frame 12 will also move with the positioning block 13. When the extension frame 12 is adjusted to a suitable height, the lever 14 can be released. At this time, under the action of the compression spring 17, the positioning pin 16 will be inserted into its corresponding positioning hole. The outward-extending extension frame 12 can protect taller items, improving the practicality of the device.
