Description

Technical Field

[0001] This utility model relates to the field of shielding box technology, specifically a stackable multi-purpose shielding box. Background Technology

[0002] A shielding box is a device made of conductive or magnetic materials. Its core function is to isolate and suppress electromagnetic interference, providing an interference-free testing environment for wireless communication equipment, electronic components, and other devices. Stackable shielding boxes are specially designed electromagnetic shielding devices. Their core advantage lies in achieving efficient space utilization through a stacking structure while maintaining electromagnetic shielding performance. They are mainly used in scenarios where flexible adjustment of testing space or storage density is required, improving both space utilization and overall electromagnetic shielding performance. However, if the shielding boxes are not effectively secured during stacking, the stability during the stacking process will be poor, and the boxes may slip due to external forces, thus reducing the service life of the shielding boxes.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202320705265.6, application date 2023-04-03) includes: a shielding box, on which a plug for a battery assembly is fixedly installed through the side wall; symmetrically distributed connectors are provided on the top of the side wall of the shielding box, and a horizontal axis on the shielding box is provided through the bottom of the connectors to form a rotation limiting structure; it also includes: a shielding cover, whose bottom surface fits and covers the upper port of the shielding box to form a sealing structure; the end of the connector away from the shielding box is fixedly connected to the side wall of the shielding cover, and a conversion connector is provided below the shielding cover, and the conversion connector is fixedly provided through the side wall of the shielding box; moreover, the shielding box and the shielding cover are made of aluminum alloy; this stackable multi-purpose shielding box has a lockable stacking structure on its body, which makes it more stable and less prone to slippage when multiple boxes are stacked; the device is also equipped with a conversion connector, and the user can control the detection product inside the device through an external terminal.

[0004] The observation window of a shielded enclosure is usually made of materials such as glass or plastic. These materials are prone to generating static electricity during friction with air and internal equipment components. Static electricity attracts dust particles, making it easier for dust to adhere to the surface of the observation window and adhere firmly, making it difficult for them to fall off on their own. During use, the aforementioned device cannot effectively reduce the amount of dust remaining on the surface of the observation window, making it difficult for operators to obtain accurate information, affecting their judgment of product quality. At the same time, it reduces the electromagnetic protection capability of the shielded enclosure for the internal equipment, making the internal equipment more susceptible to external electromagnetic interference and affecting its normal operation. Utility Model Content

[0005] The purpose of this invention is to provide a stackable, multi-purpose shielding box to solve the problems mentioned in the background art, such as the inability to effectively reduce residual dust on the surface of the observation window, which makes it difficult for operators to accurately obtain information and affects the judgment of product quality. At the same time, it reduces the electromagnetic protection capability of the shielding box for internal equipment, making the internal equipment more susceptible to external electromagnetic interference and affecting its normal operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stackable multi-purpose shielding box, comprising a shielding box, a top cover fixedly connected to the upper surface of the shielding box, and a positioning groove provided inside the top cover, with the positioning grooves being distributed at equal angles inside the top cover; a base fixedly connected to the lower surface of the shielding box; positioning posts fixedly connected to the surface of the base, with each positioning post corresponding to one of the positioning grooves; an observation window fixedly connected to the upper left side of the shielding box; a fixing plate fixedly connected to the upper front side of the shielding box, with a connecting rod fixedly connected to the surface of the fixing plate, and a cleaning rod slidably connected through the connecting rod, with the surface of the cleaning rod abutting against the surface of the observation window.

[0007] Preferably, the top cover has a sliding groove inside, and a sliding column is slidably connected to the surface of the sliding groove, and a pull plate is fixedly connected to the left side of the sliding column.

[0008] Preferably, one end of a buffer spring is fixedly connected to the surface of the pull plate near the top cover, and the other end of the buffer spring is fixedly connected to the top cover.

[0009] Preferably, the buffer springs are symmetrically distributed about the center of the top cover, and a baffle is fixedly connected to the rear side of the top cover, with a sliding rod fixedly connected to the surface of the baffle.

[0010] Preferably, the sliding rod is slidably connected to a rack, and a fixing block is fixedly connected to the upper rear side of the shielding box.

[0011] Preferably, the fixed block has a rotating shaft rotatably mounted inside, and a gear is fixedly connected to one end of the rotating shaft near the baffle, and the gear is meshed with the rack.

[0012] Preferably, the cleaning rod is threaded onto the surface of the rotating shaft, and the rack is fixedly connected to the rear side of the pull plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the stackable multi-purpose shielding box adopts a novel structural design, the specific details of which are as follows: This stackable, multi-purpose shielding box effectively reduces dust residue on the observation window surface through its cleaning rod and rotating shaft, allowing operators to clearly observe the interior of the shielding box while ensuring that the observation window maintains good observation performance and shielding capabilities throughout long-term use.

[0014] Furthermore, reducing dust residue can maintain the good electromagnetic shielding effect of the observation window, prevent electromagnetic leakage or interference, and ensure the normal operation of the equipment inside the shielding box.

[0015] This stackable multi-purpose shielding box, through its positioning slots and sliding pillars, ensures the stability of the shielding boxes when stacked, reduces the risk of tipping over due to the shift in the center of gravity of the shielding box caused by stacking deviation, and maintains the integrity of the stacked structure.

[0016] Furthermore, it helps to ensure the tightness of the connection between the shielding boxes, preventing gaps or misalignment between the shielding boxes due to unstable stacking, thereby maintaining good electromagnetic shielding performance.

[0017] (3) The stackable multipurpose shielding box reduces friction between the cleaning rod and the shielding box by setting connecting rods and fixing plates, extends the service life of the cleaning rod and the shielding box, reduces the maintenance and replacement costs of the equipment, and ensures that the entire cleaning device maintains a reliable working state during long-term use.

[0020] 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.

[0021] Example 1: The positioning groove 3, positioning post 7, and connecting rod 16 effectively protect the internal equipment from damage, extend the equipment's service life, and ensure that the equipment maintains normal operation during long-term use. Figures 1-2 As shown: It includes a shielding box 1, a top cover 2 fixedly connected to the upper surface of the shielding box 1, and a positioning groove 3 is opened inside the top cover 2. The positioning grooves 3 are evenly distributed inside the top cover 2. At the same time, a base 6 is fixedly connected to the lower surface of the shielding box 1, and a positioning post 7 is fixedly connected to the surface of the base 6. The positioning post 7 corresponds one-to-one with the positioning groove 3. An observation window 5 is fixedly connected to the upper left side of the shielding box 1. A fixing plate 17 is fixedly connected to the upper front side of the shielding box 1. A connecting rod 16 is fixedly connected to the surface of the fixing plate 17. A cleaning rod 15 is slidably connected through the connecting rod 16. At the same time, the surface of the cleaning rod 15 is in contact with the surface of the observation window 5.

[0022] The operator places the lower shielding box 1 in the predetermined position, ensuring that it is stable and does not wobble. Simultaneously, the operator aligns the positioning post 7 at the bottom of the upper shielding box 1 with the positioning groove 3 at the top of the lower shielding box 1 to avoid damaging the positioning structure. When the upper and lower shielding boxes 1 are tightly fitted together, the stacking of the shielding boxes 1 is complete. The connecting rod 16 and fixing plate 17 reduce friction between the cleaning rod 15 and the shielding box 1, extending the service life of both and reducing maintenance and replacement costs. This also ensures that the entire cleaning device maintains reliable operation throughout long-term use.

[0023] In Example 2, unlike Example 1, the sliding groove 4, pull plate 8, and buffer spring 10 effectively resist external impact forces and maintain the integrity of the stacked structure. Figures 3-4 As shown: The top cover 2 has a sliding groove 4 inside, and a sliding column 9 is slidably connected to the surface of the sliding groove 4. A pull plate 8 is fixedly connected to the left side of the sliding column 9. A buffer spring 10 is fixedly connected to one end of the surface of the pull plate 8 near the top cover 2, and the other end of the buffer spring 10 is fixedly connected to the top cover 2. The buffer springs 10 are symmetrically distributed about the center of the top cover 2. A baffle 18 is fixedly connected to the rear side of the top cover 2, and a sliding rod 19 is fixedly connected to the surface of the baffle 18.

[0024] When the shielding boxes 1 are stacked, the pull plate 8 is pulled, causing the sliding post 9 on the surface of the pull plate 8 to slide inside the sliding groove 4 inside the top cover 2. At the same time, the buffer spring 10 on the surface of the top cover 2 extends towards the surface of the pull plate 8. After the shielding boxes 1 are stacked, the pull plate 8 is released, causing the sliding post 9 on the surface of the pull plate 8 to slide inside the sliding groove 4 inside the top cover 2. This fixes the upper shielding box 1, ensuring the stability of the shielding boxes 1 when stacked, reducing the risk of tipping over due to the center of gravity shift of the shielding box 1 caused by stacking deviation, and maintaining the integrity of the stacked structure.

[0025] In Example 3, unlike Example 2, the gear 12, rack 11, and cleaning rod 15 are used to prevent electromagnetic leakage or interference, ensuring the normal operation of the equipment inside the shielding box 1. Figures 5-7 As shown: a sliding rod 19 is slidably connected to a rack 11, a fixing block 13 is fixedly connected to the upper rear side of the shielding box 1, a rotating shaft 14 is rotatably arranged inside the fixing block 13, and a gear 12 is fixedly connected to the end of the rotating shaft 14 near the baffle 18, and the gear 12 is meshed with the rack 11. A cleaning rod 15 is threadedly connected to the surface of the rotating shaft 14, and a rack 11 is fixedly connected to the rear side of the pull plate 8.

[0026] As the pull plate 8 is pulled, the rack 11 on the surface of the pull plate 8 slides on the sliding rod 19 on the surface of the baffle 18, and the rack 11 meshes with the gear 12, causing the rotating shaft 14 inside the gear 12 to rotate inside the fixed block 13. At the same time, the surface of the rotating shaft 14 is threaded with a cleaning rod 15. As the rotating shaft 14 rotates, the cleaning rod 15 slides on the surface of the connecting rod 16, effectively reducing the dust remaining on the surface of the observation window 5, allowing the operator to clearly observe the situation inside the shielding box 1, and ensuring that the observation window 5 maintains good observation effect and shielding performance during long-term use.

[0027] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] 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.
