Description

Technical Field

[0001] This utility model relates to a filter, specifically a filter with a fixed shield, and belongs to the field of filter technology. Background Technology

[0002] A USB filter is an electronic component or device specifically designed for USB interface circuits to filter USB signals. Installing a shielding cover on the outside of the filter body can prevent electromagnetic interference, protect internal components, and enhance stability. USB filters are usually installed inside electromagnetic shielding machines to ensure the quality of USB signals and prevent electromagnetic interference from affecting USB data transmission. They are also equipped with multiple USB ports for easy connection of USB devices such as mice, keyboards, and printers.

[0003] However, when installing a USB filter inside an electromagnetic shielding machine table, the USB filter is usually installed on the table wall. The table wall is usually relatively narrow. When it is necessary to insert the USB cable into the filter fixed on the table wall, and the line of sight is obstructed, it may be difficult to find a suitable angle and position for the hand to operate. Especially when other devices or components are installed inside the machine table, it will further restrict the range of hand movement and increase the difficulty of inserting the cable. Utility Model Content

[0004] The purpose of this invention is to provide a filter with a fixed shield to solve the above problems. The filter is driven to move by a flip structure, which can also cause the filter to flip at an angle so that the socket on the filter faces the operator, thereby creating a more suitable operating space for the operator and reducing the difficulty of wiring.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a filter with a fixed shielding cover includes a housing, the housing being mounted on a mounting plate via a flip structure, the flip structure including a connecting plate, the connecting plate being fixedly connected to the housing, a first rotating shaft being rotatably connected to the connecting plate, a first folding plate being fixedly connected to the first rotating shaft, a second rotating shaft being rotatably connected to the end of the first folding plate, a second folding plate being fixedly connected to the second rotating shaft, a third rotating shaft being fixedly connected to the end of the second folding plate, the third rotating shaft being rotatably connected to the mounting plate, a fixing structure being mounted on the mounting plate, and a filter body being installed inside the housing.

[0010] Preferably, the guide rod has a "T" shaped cross-section, and the guide rod is perpendicular to the locking block.

[0011] Preferably, a tension spring is sleeved on the outside of the guide rod, one end of the tension spring is fixedly connected to the locking block, and the other end of the locking block is fixedly connected to the mounting plate.

[0012] The beneficial effects of this utility model are as follows: a connecting plate is fixedly connected to the cover, a first rotating shaft is rotatably connected to the connecting plate, a first folding plate is fixedly connected to the first rotating shaft, a second rotating shaft is rotatably connected to the end of the first folding plate, a second folding plate is fixedly connected to the second rotating shaft, and a third rotating shaft is fixedly connected to the end of the second folding plate.

[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] Please see Figures 1-6 As shown, a filter with a fixed shield includes a housing 1, which is mounted on a mounting plate 5 via a flip structure 3. The flip structure 3 includes a connecting plate 301, which is fixedly connected to the housing 1. A first rotating shaft 302 is rotatably connected to the connecting plate 301, and a first folding plate 303 is fixedly connected to the first rotating shaft 302. A second rotating shaft 304 is rotatably connected to the end of the first folding plate 303, and a second folding plate 305 is fixedly connected to the second rotating shaft 304. A third rotating shaft 306 is fixedly connected to the end of the second folding plate 305. The third rotating shaft 306 is rotatably connected to the mounting plate 5. The connecting plate 301 has a U-shaped cross-section, and the first folding plate 303 has an L-shaped cross-section. A fixing structure 4 is mounted on the mounting plate 5, and a filter body 2 is installed inside the housing 1.

[0022] As a technical optimization of this utility model, the fixing structure 4 includes a locking block 401, which is slidably connected to the mounting plate 5. The connecting plate 301 has a locking groove 402, and the end of the locking block 401 engages with the locking groove 402. A tension spring 404 is sleeved on the outside of the guide rod 403. One end of the tension spring 404 is fixedly connected to the locking block 401, and the other end of the locking block 401 is fixedly connected to the mounting plate 5. The fixing structure 4 plays a role in the flipping structure 3, which can increase the stability of the filter installation. When it is necessary to insert or remove the wire, the locking block 401 is pushed outward by hand to make the locking block 401 slide outward from the mounting plate 5 and no longer engage with the locking groove 402 on the connecting plate 301. The sliding of the locking block 401 drives the tension spring 404 to extend, thereby quickly releasing the restriction on the flipping structure 3.

[0023] As a technical optimization of this utility model, the end of the card block 401 is a beveled structure, and the overall cross-section of the card block 401 is an "L" shaped structure; the beveled end of the card block 401 has a guiding effect on the card block 401, which facilitates the card block 401 to engage with the card slot 402.

[0024] As a technical optimization of this utility model, a guide rod 403 is fixedly connected to the mounting plate 5, and the locking block 401 is slidably connected to the guide rod 403. The cross-section of the guide rod 403 is T-shaped, and the guide rod 403 and the locking block 401 are perpendicular to each other. The guide rod 403 guides the sliding of the locking block 401 and prevents the locking block 401 from falling off, making the sliding of the locking block 401 more stable.

[0025] In use, the mounting plate 5 is first fixed to the table wall with bolts, thereby installing the filter inside the electromagnetic shielding machine table. The fixing structure 4 plays a role in the flip structure 3, increasing the stability of the filter installation. When it is necessary to insert or remove a wire, the locking block 401 is pushed outward by hand, causing the locking block 401 to slide outward and no longer engage with the slot 402 on the connecting plate 301. The sliding of the locking block 401 causes the tension spring 404 to extend, thereby quickly releasing the restriction on the flip structure 3. When the locking block 401 no longer restricts the connecting plate 301, under the action of gravity, the cover 1 drives the first folding plate 303 to rotate downward through the connecting plate 301, so that the cover 1 and the table... The increased distance of the wall brackets provides rotation space for the second hinge plate 305. Then, the second hinge plate 305 rotates around the third pivot 306, moving the cover 1 towards the operator and bringing the cover 1 closer to the operator, making operation more convenient. Next, the connecting plate 301 and the cover 1 rotate around the first pivot 302, allowing for more precise control of the cover 1's flipping direction and angle, ensuring the sockets on the cover 1 face the operator, thus creating a more suitable operating space and reducing the difficulty of wiring. Installing the filter body 2 inside the cover 1 prevents external electromagnetic interference from entering the filter, ensuring accurate signal processing and preventing electromagnetic leakage from the filter itself, thus avoiding interference with other equipment.
