Description

Technical Field

[0001] This utility model relates to the field of shielding box technology, and in particular to a shielding box with four independent compartments. Background Technology

[0002] A shielding box is a box used to shield the external electromagnetic environment. Traditional shielding boxes are mostly of the structure of ordinary boxes. This structure requires manual opening each time it is used, which is inconvenient to operate. Moreover, only one workpiece can be put into the shielding box for testing at a time, resulting in low testing efficiency and failing to meet the needs of actual production applications.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a shielded box with four independent compartments, which can simultaneously test multiple workpieces in a shielded environment, improve testing efficiency, and meet the needs of actual production applications.

[0005] The technical solution of this utility model is as follows: A shielded box with four independent compartments is provided, comprising: a frame, a test compartment, a first linear moving device, two first guide rails, a moving rod connected to the output end of the first linear moving device, a first slider cooperating with the first guide rails, a support plate mounted on the first slider, a second linear moving device mounted on the support plate, a telescopic cover connected to the output end of the second linear moving device, and a plurality of shielding covers mounted on the telescopic cover; the test compartment includes a plurality of test positions, and the shielding covers cooperate with the test positions; the first slider is connected to the moving rod and the support plate respectively, and the test compartment is disposed between the two first guide rails. The first and second linear moving devices are pneumatic cylinders or electric cylinders.

[0006] When a workpiece needs to be tested in an electromagnetically shielded environment, the workpiece is placed on the test position. Then, the first linear motion device moves, driving the telescopic cover upwards towards the test chamber. Once the telescopic cover is above the test chamber, the second linear motion device moves, retracting the telescopic cover to cover the workpiece, thus providing a shielded environment. After the test, the second linear motion device lifts the telescopic cover, removing it from the workpiece. Then, the first linear motion device moves, removing the telescopic cover from above the test chamber. The operator can then remove the tested workpiece from the test position and reposition it for testing in the electromagnetically shielded environment. This invention enables automatic closing and opening of the shielding cover, greatly facilitating user operation. Furthermore, it allows multiple workpieces to be tested simultaneously in a shielded environment, significantly improving testing efficiency and meeting practical application needs.

[0007] Furthermore, the four-compartment independent compartment shielding box also includes: a first buffer installed at both ends of the first guide rail. The first buffer is used to cushion the impact of the first slider when it moves on the first guide rail.

[0008] Furthermore, the four-compartment independent compartment shielding box also includes: a guide rod connected to the telescopic cover, a second slider connected to the guide rod, and a second guide rail mounted on the support plate; the second slider cooperates with the second guide rail. The guide rod is used to guide the telescopic cover's extension and retraction, reducing swaying during the extension and retraction process.

[0009] Furthermore, the four-compartment independent compartment shielding box also includes a second buffer mounted on the support plate, the second buffer being disposed on one side of the guide rod. The second buffer provides cushioning when the telescopic cover moves.

[0010] Furthermore, the four-compartment independent compartment shielding box also includes: a mounting block installed on the first slider, wherein the first slider is connected to the moving rod and the support plate respectively through the mounting block.

[0011] Furthermore, there are 4 test positions and 4 shielding covers.

[0012] By adopting the above solution, this utility model provides a shielded box with four independent compartments. Through the movement of the telescopic cover by the first linear moving device and the second linear moving device, the shielded cover can be automatically closed and opened, which can greatly facilitate the user. At the same time, multiple workpieces can be tested in a shielded environment at the same time, which can significantly improve the testing efficiency and meet the needs of practical applications.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Please see Figures 1-4This embodiment provides a shielded box with four independent compartments, comprising: a frame 10; a test chamber 11, a first linear motion device 12, and two first guide rails 13, all mounted on the frame 10; a moving rod 14 connected to the output end of the first linear motion device 12; a first slider 15 cooperating with the first guide rails 13; a support plate 16 mounted on the first slider 15; a second linear motion device 17 mounted on the support plate 16; a telescopic cover 18 connected to the output end of the second linear motion device 17; and a plurality of shielding covers 19 mounted on the telescopic cover 18. The test chamber 11 includes a plurality of test positions 20, and the shielding covers 19 cooperate with the test positions 20. The first slider 15 is connected to the moving rod 14 and the support plate 16, and the test chamber 11 is disposed between the two first guide rails 13. The first linear motion device 12 and the second linear motion device 17 are pneumatic cylinders or electric cylinders.

[0019] When a workpiece needs to be tested in an electromagnetically shielded environment, the workpiece is placed on the test position 20. Then, the first linear motion device 12 operates, driving the telescopic cover 18 to move above the test chamber 11. After the telescopic cover 18 moves above the test chamber 11, the second linear motion device 17 operates, retracting the telescopic cover 18, and the shielding cover 19 covers the workpiece, thus providing a shielded environment for the workpiece. After the test is completed, the second linear motion device 17 operates, lifting the telescopic cover 18, and the shielding cover 19 no longer covers the workpiece. Then, the first linear motion device 12 operates, removing the telescopic cover 18 from above the test chamber 11. The operator can then remove the tested workpiece from the test position and replace the workpiece that needs to be tested in a shielded environment for testing in an electromagnetically shielded environment. This utility model can realize the automatic closing and opening of the shielding cover 19, which can greatly facilitate the user; at the same time, multiple workpieces can be tested in a shielded environment at the same time, which can significantly improve testing efficiency and meet practical application needs.

The guide rod 22 is used to guide the telescopic cover 18 to extend and retract, reducing swaying during the extension and retraction process.

[0022] In this embodiment, the four-compartment independent compartment shielding box further includes a second buffer 25 mounted on the support plate 16, the second buffer 25 being disposed on one side of the guide rod 22. The second buffer 25 is used to provide cushioning when the telescopic cover 18 moves.

[0023] In this embodiment, the four independent compartment shielding box further includes: a mounting block 26 installed on the first slider 15, and the first slider 15 is connected to the moving rod 14 and the support plate 16 respectively through the mounting block 26.
