Description of the invention: [Technical field to which the invention pertains] The present invention relates to an isolation environment, and more particularly to an isolation box. [Prior Art] With the rapid development of the electronics industry, electronic products tend to be light and thin in terms of type, and gradually become a high-performance, high-function, high-speed research and development direction in terms of functions. General electronic products are subject to specification testing, such as electromagnetic interference testing, to enable electronic products to comply with relevant regulations. When testing, the electronic product is placed in an isolated environment, such as a shielding room, or a shielding box. See Figure 1, for the isolation environment. The isolation box 1 for the conventional detection includes a case 12 having an opening 120, a door panel 13 opening and closing the opening 120, a partitioning plate 14 disposed on the door panel 13, and a latch connecting the door panel 13 and the cabinet 12. 15 and hinge 16. The inner wall surface of the casing 12 has a partitioning material, and the door panel 13 has a rib 130, and the casing 12 has a groove 121 for engaging the rib 130. Further, the spacer 14 is loosely fitted to the inner wall surface around the opening 120. The latch 15 is a manual latch and is made of steel. However, when the door panel 13 is opened, the door latch 15 needs to be manually opened, so that after the door panel 13 is used for multiple opening and closing, the door latch 15 is easily loosened by wear, so that the ridges 130 of the door panel 13 and the door panel 13 are The groove 121 of the casing 12 cannot maintain the tightness, which causes the isolation box 1 to be poorly sealed, so that the signal is easily leaked from the opening 120 and the periphery of the door 15. Furthermore, the hinges 16 used in the conventional isolation box 1 are asymmetrical and 3 112024 201244597 rows of two steel sheets 160 are respectively fixed to the box body 12 and the door panel 13, and the door panel 13 is driven by the rotating shaft 161. Opening and closing. Because the two steel sheets 16 are asymmetrically side by side, after the door panel 13 is used for multiple opening and closing, the two steel sheets 16 are easily deformed and loosened, so that the door panel 13 and the box 12 cannot maintain close contact, resulting in the door panel 13 being unable to maintain close contact with the box 12 The isolation box 1 is poorly sealed, causing the signal to be easily circulated from around the opening 120. Therefore, how to avoid the problem that the above-mentioned prior art "the door panel and the cabinet cannot be kept in close contact" is the current goal to be solved. SUMMARY OF THE INVENTION In order to overcome the problems of the prior art, the present invention provides an isolation box, which mainly improves the door panel, and avoids the problem that the isolation box is sealed and the signal is leaked regardless of the state of the door latch or the hinge. . The door panel of the present invention is hingedly hinged to one side of the box for closing the opening, and the door panel has an outer panel on the outer side, an inner panel on the inner side, and is disposed between the outer panel and the inner panel to maintain The spring of the inner plate is elastically biased. & The isolation box of the present invention has a two-layered prevention of leakage by the door panel of the two-layer plate (inner plate and outer plate). Furthermore, by the spring, the inner plate is elastically biased, so that the outer plate and the inner plate can have a buffering and pressing function, so that the position of the inner plate can be appropriately adjusted after the door plate covers the opening. The inner plate is sealed to the opening, so that the door panel of the double-layer plate (the inner plate and the outer plate) effectively seals the isolation box, thereby avoiding the sealing failure between the inner plate and the outer plate and causing the signal to leak out. .

As shown in Figure 2A, the door The plate 3 is in an open state, and the inner plate 32 can be pressed toward the direction p of the outer plate 31, and the inner plate 32 will be springed back by the spring 33. The spacer 4 is attached to The inner panel 32 is disposed between the partitioning plate 4 and the outer panel 31, and the area of the inner panel 32 is larger than the area of the partitioning panel 4 as shown in FIG. 2A. In this embodiment, The spacer 4 is loosely fitted to the inner surface 22& of the side panel 22 around the opening 2〇. The isolation box of the present invention is used for elastically yawing the inner panel 32 by the spring 33, so that the outer panel 31 is The buffering and pressing between the inner plates 32 is such that when the distal door 3 covers the opening 20, the ribs 31 of the outer plate 31 engage the grooves 23 around the opening 20, and at the same time, the spring 33 can be appropriately Adjusting the position of the inner panel 32 (moving from the outer panel 31 toward the opening 2, ie, from 112024 7 201244597), so that the first step 320 of the inner panel 32 is engaged with the second body 320 The second-order portion 24 seals the opening 20 to prevent the signal from leaking between the outer panel 31 and the inner panel 32 to cause leakage of the signal. When the first-order portion 32〇 and the second-order portion 24 of the casing 2 cannot be effectively engaged due to wear or other factors, the inner panel 32 and the outer panel 31 are kept at a predetermined distance because the length of the cylinder is reserved. The inner plate 32 is displaced to the proper position by the spring 33 to seal the opening 20. Further, the second groove 312 does not penetrate the outer plate 31, thereby avoiding the signal from the outside of the second groove 312 during detection. Moreover, the spacing D between the outer panel 31 and the inner panel 32 can provide displacement of the inner panel 32 relative to the outer panel 31 (as shown in FIG. 3C, the displacement direction L), so the first recess 312 The depth d is greater than the height h of the cap 300a to reserve a space for displacement. In addition, the column 300 may also be telescopic, such that the degree of the second groove is equal to the height of the head, and there is no need to reserve a space for displacement.
