Description

Technical Field

[0001] This application relates to the technical field of electromagnetic radiation shielding devices, and in particular to a shielding device for electromagnetic wave radiation. Background Technology

[0002] During the testing of electronic components, communication equipment and other products, electromagnetic interference can cause test data distortion, equipment malfunction or abnormality of surrounding instruments, which seriously affects the accuracy and reliability of test results. When frequently picking up and putting down the test component during the test, the shielding structure needs to be repeatedly disassembled and reassembled, which is cumbersome. Conventional shielding cavities lack a locking mechanism, and test vibration or accidental contact may cause the shielding cover to shift, creating electromagnetic leakage gaps.

[0003] Therefore, those skilled in the art have provided a shielding device for electromagnetic wave radiation to solve the problems mentioned in the background art. Utility Model Content

An adjustment component is installed at the rear center of the inner side of the shielding cover assembly. An upper shielding cover is installed at the front end of the adjustment component. The adjustment component includes a guide rail. A first mounting block is fixedly connected to the top end of the guide rail. A threaded rod is rotatably connected to the upper and lower ends of the first mounting block. A handle is fixedly connected to the top end of the threaded rod. A movable block is threadedly connected to the outer side of the threaded rod. A vertical plate is fixedly connected to the front end of the movable block.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By adjusting the threaded rod and moving block in the assembly, rotating the handle drives the upper shielding cover to rise and fall, avoiding electromagnetic leakage caused by spatial mismatch.

[0019] Example 1

[0020] like Figure 1-3 As shown, this application discloses an electromagnetic wave radiation shielding device, including a placement platform 3. A shielding cover assembly 2 is installed at the bottom of the placement platform 3. An adjustment assembly 1 is installed at the center and rear of the inner side of the shielding cover assembly 2. An upper shielding cover 4 is installed at the front end of the adjustment assembly 1. The adjustment assembly 1 includes a guide rail 101. A first mounting block 102 is installed at the top of the guide rail 101. A threaded rod 103 is installed through the upper and lower ends of the first mounting block 102. A handle 104 is installed at the top of the threaded rod 103. A moving block 105 is installed on the outer side of the threaded rod 103. A vertical plate 106 is installed at the front end of the moving block 105. The front end of the vertical plate 106 is fixedly connected to the side wall of the upper shielding cover 4. A rotating assembly is installed at the bottom of the guide rail 101.

[0021] Rotating the handle 104 causes the threaded rod 103 mounted on the first mounting block 102 to rotate. The threaded rod 103 causes the moving block 105 to move within the guide rail 101. The moving block 105 causes the vertical plate 106 and the upper shielding cover 4 to move. The upper shielding cover 4 can be lowered to shield the test piece placed on the placement platform 3 from electromagnetic radiation. The upper shielding cover 4 can be raised to facilitate the placement of the test piece on the placement platform 3.

[0022] like Figure 1 As shown, the shielding cover assembly 2 includes a bottom shielding cover 201. Two sets of mounting plates 202 are installed at the front end of the bottom shielding cover 201. A shielding plate 203 is installed on the inner side of the mounting plate 202. The bottom shielding cover 201, together with the shielding plate 203, can shield the test piece on the placement platform 3 from electromagnetic radiation. The shielding plate 203 can be disassembled to facilitate cleaning inside the shielding cover assembly 2.

[0023] like Figure 1 , 4 As shown, the rotating assembly includes a housing 109, a rotating shaft 110 is mounted on the inner side of the housing 109, a second mounting block 111 is mounted on the upper end of the rotating shaft 110, the upper end of the second mounting block 111 is fixedly connected to the guide rail 101, a mounting groove 112 is provided through the upper end of the housing 109 near the edge, a spring 113 is mounted on the bottom end of the inner side of the mounting groove 112, a ball bearing 114 is mounted on the top end of the inner side of the mounting groove 112, and two fixing holes 115 are provided on the bottom end of the second mounting block 111, the angle between the two fixing holes 115 is a right angle, the second mounting block 111 can rotate between the rotating shaft 110 and the housing 109, the spring 113 pushes the ball bearing 114 to cooperate with the fixing holes 115 to limit the second mounting block 111 and the rotating shaft 110.

[0024] like Figure 1-3As shown, side plates 107 are installed on both sides of the vertical plate 106, and vertical grooves 108 are opened on both sides of the guide rail 101. The protrusions on the side plates 107 are set in the vertical grooves 108. By setting the side plates 107 in conjunction with the vertical grooves 108, the movement stability of the moving block 105, the vertical plate 106 and the upper shield 4 can be improved.

[0025] like Figure 1 As shown, the outer walls of the bottom shield 201, the shield plate 203, and the upper shield 4 are all coated with MOF composite material. The electromagnetic wave shielding effect can be enhanced by setting MOF composite material.

[0026] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] The implementation principle of an electromagnetic radiation shielding device according to an embodiment of this application is as follows:

[0029] In use, the test piece is placed on the placement platform 3. Rotating the handle 104 drives the threaded rod 103 to rotate, driving the moving block 105 to move vertically along the guide rail 101, causing the upper shield 4 to descend to near the bottom shield 201. When it is necessary to remove the upper shield 4, rotate the handle 104 in the opposite direction. After the upper shield 4 rises, it can be pushed to rotate to one side to avoid obstructing the installation of the test piece. The upper shield 4 drives the second mounting block 111 and the rotating shaft 110 to rotate. When the rotating shaft 110 rotates, the spring 113 pushes the ball 114 to engage with the fixing hole of the second mounting block 111. 115, to achieve limit position, ensure that the upper shield 4 is fixed in position. The closed shield (upper shield 4, bottom shield 201, shield plate 203) absorbs electromagnetic wave energy through MOF coating. The remaining interference is attenuated by multiple reflections through the inner wall of the cavity, blocking the electromagnetic interaction between the inside and outside. The detachable design of shield plate 203 facilitates quick cleaning after testing and maintains the integrity of the shielding structure. After testing, rotate handle 104 in the opposite direction to lift the upper shield 4 and directly pick up and put in the test piece, avoiding repeated disassembly and assembly. After removing the side shield plate 203, the placement platform 3 and the inside of the cavity can be cleaned or maintained.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
