Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding technology, specifically to a shielding cover that is easy to install and disassemble. Background Technology

[0002] Currently, many electronic products contain complex circuit boards with numerous integrated electronic components to achieve various functions. To improve the stability and reliability of the circuit board operation and avoid electromagnetic interference, a common method is to install an electromagnetic shield around the circuit board, enclosing all electronic components inside. This isolates the components from external electromagnetic interference and reduces the interference caused by electromagnetic signals generated by the components during operation, ensuring the normal operation of each electronic component. To achieve optimal shielding performance and the best stability and reliability, the electromagnetic shield should ideally employ a fully enclosed structure.

[0003] Existing technology, such as the easily detachable electromagnetic shielding cover disclosed in patent publication number CN219698357U, includes a cover body composed of columns and a frame. A stretch curtain is connected to the front of the cover body, and double-layer acrylic plates are connected to the top, sides, and rear of the cover body. A brass mesh is connected between the two acrylic plates. A heat-conducting layer is provided on the inner side of the top surface of the cover body, and a heat dissipation component is provided on its outer side. This utility model adopts the aforementioned easily detachable electromagnetic shielding cover. By placing a brass mesh between the two acrylic plates and inside the cover body, it can effectively shield electromagnetic interference signals, exhibiting strong stability. Furthermore, it has excellent heat dissipation function, is easy to install and disassemble, and the entire frame is detachable, making transportation more convenient.

[0004] In practical use, the side of the shielding cover where the stretch curtain is installed does not have a brass mesh, resulting in a defect within the shielding range. Opening one side makes it inconvenient to inspect and repair electronic components that are far from that side.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a shielding cover that is easy to install and disassemble, which can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: a shielding cover that is easy to install and disassemble, comprising: a shell, a cover plate, a shielding component for shielding electromagnetic signals, a guide component for restricting the movement of the cover plate, and a fixing component for fixing the cover plate;

[0008] The guiding assembly includes: two guide rods fixedly installed at one end on the inner wall of the housing; the guide rods are symmetrically arranged on both sides of the mounting frame and slidably installed on the guide post; the moving block is fixedly installed at one end of the top of the cover plate and slidably installed in a first groove at the other end of the guide rod; a connecting spring fixedly connecting the bottom of the first groove and the connecting rod; and a limiting rod fixedly connecting the connecting rod. A limiting block is fixedly installed at the end of the limiting rod away from the guide rod.

[0009] Furthermore, the fixing assembly includes: grooves symmetrically arranged on the inner wall of the housing, a support plate slidably installed in the groove, a support spring fixedly installed between the support plate and the bottom of the groove, a fixing rod hinged to the bottom of the support plate, a fixing block fixedly installed at the other end of the fixing rod, a second slide groove provided at the bottom of the groove, a threaded hole provided at the bottom of the second slide groove, a bolt threaded in the threaded hole, and a positioning block rotatably installed at the bottom of the bolt, the positioning block being slidably installed in the second slide groove.

[0010] Furthermore, the shielding assembly includes: a mounting bracket fixedly installed at the bottom of the inner wall of the housing, a movable bracket slidably installed at the top of the mounting bracket, the movable bracket being fixedly installed at the bottom of the cover plate, brass mesh fixedly installed on the side, bottom and top of the mounting bracket, and a support plate fixedly installed at the bottom of the inner wall of the mounting bracket.

[0011] Furthermore, the positioning block is slidably mounted on the bottom of the fixing rod in a horizontal state.

[0012] Compared with the prior art, the present invention has the following advantages: The present invention provides a shielding cover that is easy to install and disassemble. Electronic components are fixedly mounted on the support plate. The sides, bottom and top of the mounting bracket are provided with brass mesh to shield electromagnetic signals, resulting in good shielding effect.

[0013] The cover plate drives the movable frame to slide on the top of the mounting frame. When the cover plate is opened, it drives the movable plate to open. The limit rod prevents the cover plate from driving the movable block to disengage from the guide rod, so that the cover plate does not obstruct the electronic components on the carrier plate, making it convenient to inspect and maintain the electronic components from the top of the mounting frame.

[0022] like Figures 1 to 4As shown, the present invention provides a shielding cover that is easy to install and disassemble, comprising: a housing 101, a cover plate 102, the cover plate 102 being composed of a top cover and a vertical plate, the top cover being slidably mounted on the top of the housing 101, a shielding component 200 for shielding electromagnetic signals, a guide component 300 for restricting the movement of the cover plate 102, and a fixing component 400 for fixing the cover plate 102.

[0023] The guide assembly 300 includes: two guide rods 302 fixedly installed at one end on the inner wall of the housing 101; the guide rods 302 are symmetrically arranged on both sides of the mounting frame 201 and slidably installed on the guide post; the moving block 301 is fixedly installed at one end of the top of the cover plate 102 and slidably installed in a first groove at the other end of the guide rod 302; a connecting spring 303 fixedly connecting the bottom of the first groove and the connecting rod 304; and a limiting rod 305 fixedly connecting the connecting rod 304. A limiting block is fixedly installed at the end of the limiting rod 305 away from the guide rod 302.

[0024] The fixing assembly 400 includes: a groove 403 symmetrically arranged on the inner wall of the housing 101; a support plate 401 slidably installed in the groove 403; a support spring 402 fixedly installed between the support plate 401 and the bottom of the groove 403; a fixing rod 404 hinged to the bottom of the support plate 401, with a fixing block fixedly installed at the other end of the fixing rod 404; a second sliding groove provided at the bottom of the groove 403; a threaded hole 407 provided at the bottom of the second sliding groove; a bolt 406 threadedly installed in the threaded hole 407; and a positioning block 405 rotatably installed at the bottom of the bolt 406, with the positioning block 405 slidably installed in the second sliding groove.

[0025] The shielding assembly 200 includes: a mounting bracket 201 fixedly installed on the bottom of the inner wall of the housing 101, a movable bracket 202 slidably installed on the top of the mounting bracket 201, the movable bracket 202 being fixedly installed on the bottom of the cover plate 102, a brass mesh 203 fixedly installed on the side, bottom and top of the mounting bracket 201 and the movable bracket 202, and a support plate 204 fixedly installed on the bottom of the inner wall of the mounting bracket 201.

[0026] In this invention, brass mesh 203 is provided on all six sides of the electronic components on the support plate 204 to shield electromagnetic signals, thereby improving the shielding effect. The brass mesh 203 above the electronic components is moved away by the cover plate 102, so that the electronic components on the support plate 204 can be directly observed, which facilitates the inspection and maintenance of the electronic components. Pushing the cover plate 102 moves the moving block 301 to contact the inner wall of the housing 101, and pushes the support plate 401 to move. The fixing rod 404 driven by the support plate 401 is blocked and rotated by the positioning block 405, so that the fixing block at the top of the fixing rod 404 moves to one end of the moving block 301, fixing the moving block 301, and further fixing the cover plate 102.

[0027] Furthermore, heat sinks 104 are fixedly installed in the openings on both sides of the housing 101, and heat-conducting plates 103 are fixedly installed in a linear array on the side of the heat sinks 104. One end of the heat-conducting plate 103 contacts the brass mesh 203 on both sides of the mounting bracket 201.

[0028] Working principle: Electronic components are mounted on the support plate 204. Pushing the vertical plate causes the cover plate 102 to move the moving block 301 along the guide rod 302. The moving block 301 moves until it contacts the inner wall of the housing 101, pushing the support plate 401 to move. The support plate 401 compresses the support spring 402, causing the fixing rod 404 to move. The fixing rod 404 contacts the positioning block 405 and is blocked by the positioning block 405, causing it to rotate. The fixing rod 404 rotates to a horizontal position, causing the fixing block to fix the moving block 301, thus fixing the cover plate 102. The brass on the moving frame 202 and the mounting frame 201... The mesh 203 surrounds the electronic components on six sides. During inspection and maintenance, rotating the bolt 406 causes the positioning block 405 to slide into the second groove. The end of the fixing rod 404 falls down, and the fixing block disengages from the side of the moving block 301, allowing the cover plate 102 to move. Pushing the cover plate 102 open, the moving block 301 pushes the limiting block, and the limiting block drives the connecting rod 304 to stretch the connecting spring 303, causing the moving block 301 to drive the cover plate 102 to disengage from the top of the housing 101. This facilitates the inspection and maintenance of electronic components at various positions on the carrier plate 204, thereby improving the shielding effect and installation and disassembly efficiency.
