[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0023] Reference Figures 1-5As shown, this utility model provides a technical solution: a metal product protection device for selling metal products, including a first display stand 1. A first transparent observation cover 2 is rotatably connected to one side of the top of the first display stand 1 via a rotating shaft. Five first sliding grooves 3 are opened at the top of the interior of the first display stand 1. A first clamping rod 4 is slidably connected to the inner wall of the first sliding groove 3. A first spring 5 is fixedly connected to one side of the inner wall of the first clamping rod 4. The other end of the first spring 5 is fixedly connected to one side of the inner wall of the first sliding groove 3. A first holding slot 6 is opened inside the first display stand 1. Five first information boards 7 are fixedly connected to the inner wall of the first display stand 1. A first top plate 8 is fixedly connected to one end of the first clamping rod 4. Two first storage layers 9 are opened at the bottom of the interior of the first display stand 1. When the user needs to display the metal product, the first transparent observation cover 2 is rotated and opened via the rotating shaft. At this time, the first clamping rod 4 moves along the inner wall of the first sliding groove 3, so that the first clamping rod 4 squeezes the first spring 5, causing the first spring 5 to store and compress. When the user places the metal product in the first holding slot... Inside the first container 6, the first clamp 4 is released, causing the first spring 5 to release and push the first clamp 4 back, so that the first top plate 8 installed at one end of the first clamp 4 forms a clamp with one side of the inner wall of the first holding tank 6, fixing the position of the metal product. After the metal product is fixed, the user rotates the first transparent observation cover 2 through the pivot, so that the first transparent observation cover 2 and the first display stand 1 are closed. The user can then view the information displayed on the first information board 7 through the first transparent observation cover 2. The metal product is firmly clamped by the first clamp 4 and one side of the inner wall of the first holding tank 6, so that metal ornaments of different shapes or hardware tools of different sizes can be accurately fixed in the device. This not only ensures that the metal product will not shift or tip over due to external collision or accidental touch during the display process, avoiding the risk of damage caused by falling, but also keeps the metal product in a stable position in the device. Through simple operation, users can quickly complete the fixing and display preparation of metal products without professional knowledge or special tools.
[0024] Reference Figure 3 and Figure 4 As shown in this embodiment: First guide grooves 10 are provided at both ends of the first slide groove 3. First sliders 11 are slidably connected to the inner wall of the first guide grooves 10. One side of the first slider 11 is fixedly connected to the surface of the first clamping rod 4. When the user moves the first clamping rod 4 through the first sliders 11 at both ends inside the first guide grooves 10 at both ends of the first slide groove 3, the movement trajectory of the first clamping rod 4 is fixed, making the first clamping rod 4 more stable during operation.
[0025] Reference Figure 3 and Figure 4As shown in this embodiment: a first protective pad 12 is installed on one side of the inner wall of the first holding tank 6. When the user clamps the metal product with the first clamping rod 4 and the inner wall of the first holding tank 6, the first protective pad 12 installed on the inner wall of the first holding tank 6 prevents the metal product from being scratched or worn due to direct contact with the hard inner wall, thus effectively protecting the appearance integrity of the metal product.
[0026] Reference Figure 1 As shown in this embodiment: First brackets 13 are fixedly connected to both sides of the first display stand 1. First pneumatic support feet 14 are installed on the top of the first brackets 13. First moving assist devices 15 are installed around the bottom of the first display stand 1. When the user is about to move the device to another position, the user drives the first pneumatic support feet 14 installed on the top of the first brackets 13 to extend and retract the support feet at their telescopic ends upward through the controller, so that the first moving assist device 15 contacts the ground. The user can move the device through the first moving assist device 15. The first moving assist device 15 can flexibly change the direction of movement of the device, improve the convenience of moving the device, and make it more convenient and effortless for the user to move the device.
[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, in this embodiment: a first ventilation perforated plate 16 is provided at the bottom of the inner wall of the first holding tank 6; a first ventilation slot 17 is installed inside the first display stand 1; a first dust extraction fan 18 is installed at one end of the first ventilation slot 17; a first exhaust hose 19 is installed on one side of the first display stand 1; a first ventilation bracket 20 is installed at one end of the first exhaust hose 19; a second bracket 21 is slidably connected to the inner wall of the first ventilation bracket 20; one end of the second bracket 21 is rotatably connected to a first sealing top plate 23 via a rotating shaft; the first ventilation bracket 20... Both sides are rotatably connected to the first clamping block 24 via a rotating shaft. One end of the first clamping block 24 is inserted into the inner wall of the first sealing top plate 23. When the user places a metal product inside the device for display, the user drives the first dust extraction fan 18 through the controller. The first dust extraction fan 18 then extracts dust from the inside of the first holding tank 6 through the first ventilation slot 17 and the first ventilation perforated plate 16. At this time, the extracted air is then introduced into the first air filter element 22 installed inside the second bracket 21 inside the first ventilation bracket 20 via the first exhaust hose 19. The air is filtered and then discharged through the ventilation holes at the bottom of the second bracket 21 and the first ventilation bracket 20. When the second bracket 21 needs to be replaced, the user rotates the first clamp 24 through the shaft, causing the first sealing top plate 23 to rotate through the shaft and unfold. Then, the second bracket 21 is moved out along the guide groove inside the first ventilation bracket 20 through the rotating wheels on both sides. Then, the first air filter element 22 is moved out or replaced from the inside of the second bracket 21. The first dust extraction fan 18 exhausts the air inside the first display stand 1 and then filters it through the first air filter element 22, effectively maintaining a clean environment inside the device. This prevents metal products from being corroded or affecting the display effect due to dust accumulation. The filtered air also ensures the quality of the surrounding air, providing good environmental conditions for the display site. The replaceable filter components also reduce maintenance costs and difficulties. Users can complete maintenance work without complicated operations, improving the efficiency and sustainability of the device and ensuring that a clean storage space is always provided for metal products during long-term display.
[0028] Reference Figure 3 and Figure 5 As shown in this embodiment: a first extension block 25 is fixedly connected to one side of the first sealing top plate 23, and a first sliding buckle 26 is slidably connected to the first extension block 25. The inner wall of the first sliding buckle 26 is slidably connected to the surface of the first clamping block 24. When the user rotates the first clamping block 24 through the pivot, so that the first clamping block 24 is inserted into the inner wall of the first sealing top plate 23, the first sliding buckle 26 is moved along the inner wall of the first extension block 25, so that the first sliding buckle 26 restricts the first clamping blocks 24 on both sides, preventing them from unfolding to both sides. The first sliding buckle 26 makes the connection between the first sealing top plate 23 and the first ventilation bracket 20 more secure.
[0029] Reference Figure 3 and Figure 5 As shown in this embodiment: a first limiting rod 27 is installed inside the second bracket 21. The surface of the first limiting rod 27 is inserted into the inner wall of the first air filter element 22. When the user installs the first air filter element 22 into the second bracket 21 through the first limiting rod 27, the first limiting rod 27 fixes the first air filter element 22 and prevents it from shaking freely inside the second bracket 21.
[0030] Working principle:
[0031] Step 1: When the user needs to display a metal product, firstly, the first transparent observation cover 2 is rotated and unfolded via the pivot. Then, the first clamping rod 4 is moved along the inner wall of the first sliding groove 3, causing the first clamping rod 4 to squeeze the first spring 5, allowing the first spring 5 to store and compress. Subsequently, the metal product is placed inside the first holding groove 6, and the first clamping rod 4 is released. At this time, the first spring 5 is released and rebounds, pushing the first clamping rod 4 so that the first top plate 8 installed at one end forms a clamp with one side of the inner wall of the first holding groove 6, thereby fixing the position of the metal product. After the metal product is fixed, the user rotates the first transparent observation cover 2 via the pivot to close it with the first display stand 1. Afterward, the user can view the information displayed on the first information board 7 through the first transparent observation cover 2. This design firmly clamps the metal product by the first clamping rod 4 and one side of the inner wall of the first holding groove 6, and can accurately fix metal ornaments of various shapes or hardware tools of different sizes inside the device.
[0032] Step two: When the user operates the device, the first sliders 11 at both ends of the first clamping rod 4 move along the inner wall of the first guide grooves 10 at both ends of the first slide groove 3, fixing the movement trajectory of the first clamping rod 4 and making its operation more stable. When the metal product is clamped on one side of the inner wall of the first clamping rod 4 and the first holding groove 6, the first protective pad 12 on the inner wall of the first holding groove 6 prevents the metal product from being scratched or worn due to direct contact with the hard wall. The special texture on the surface of the first protective pad 12 further increases the friction, ensuring that the metal product is stable in the device. Even if it encounters slight shaking or vibration, it can maintain a fixed position and will not easily slide or deviate. When the user is ready to move the device, the controller drives the first pneumatic support foot 14 at the top of the first bracket 13 to extend and retract the support foot at its telescopic end, so that the first moving assist device 15 contacts the ground, thereby flexibly changing the moving direction of the device through the first moving assist device 15.
[0033] Step 3: When the user places metal products inside the device for display, the controller first drives the first dust extraction fan 18 to extract dust from the inside of the first holding tank 6 through the first ventilation slot 17 and the first perforated plate 16. Then, the extracted air is filtered through the first exhaust hose 19 and the first air filter 22 installed inside the second bracket 21 within the first ventilation bracket 20. The air is then discharged through the ventilation holes at the bottom of the second bracket 21 and the first ventilation bracket 20. When the second bracket 21 needs to be replaced, the user rotates the first clamp 24 via the pivot to unfold the first sealing top plate 23. The second bracket 21 is then moved out along the guide groove inside the first ventilation bracket 20 via the rotating wheels on both sides. The first air filter 22 is then removed or replaced from inside the second bracket 21. The first dust extraction fan 18 exhausts the air inside the first display stand 1, which is then filtered by the first air filter 22, effectively maintaining a clean environment inside the device and preventing corrosion or damage to the metal products due to dust accumulation. The system enhances the display effect and ensures the quality of the surrounding air after filtration, providing a good environment for the display site. The replaceable filter components reduce maintenance costs and difficulties, allowing users to complete maintenance without complicated operations, thus improving the efficiency and sustainability of the device. It ensures that a clean storage space is always provided for metal products during long-term display. When the user rotates the first clamping block 24 through the pivot to form an insertion with the inner wall of the first sealing top plate 23, the first sliding buckle 26 is moved along the inner wall of the first extension block 25, restricting the first clamping blocks 24 on both sides so that they cannot be unfolded to the sides. The first sliding buckle 26 makes the connection between the first sealing top plate 23 and the first ventilation bracket 20 more secure. When the user installs the first air filter element 22 into the second bracket 21 through the first limiting rod 27, the first limiting rod 27 fixes the first air filter element 22, preventing it from shaking freely in the second bracket 21.
