[0088] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0089] In existing technology, darkroom testing equipment includes a darkroom and a testing device. The testing device and the object under test are placed inside the darkroom. When the darkroom is closed, the object under test is tested by the testing device. The object under test includes electronic components such as receivers. Existing darkrooms typically have an opening on the top or side, which is opened or closed via a door. When the door is open, the object under test is placed or removed through the opening. This type of darkroom is usually only suitable for one type of testing device and cannot be used with other types. Furthermore, due to the small opening size and limited operating space, it is inconvenient for operators, resulting in poor versatility and inconvenient operation. In addition, darkrooms are usually made of metal, making them heavy and difficult to open and move, while also incurring high manufacturing costs. When the door is open, the lack of supporting structure allows the door to close accidentally, affecting safety. To solve the above problems, embodiments of this utility model provide a darkroom device and a darkroom testing system.

[0090] The following is combined with Figures 1 to 10 A darkroom device according to an embodiment of the present invention is described.

[0091] like Figures 1 to 5 As shown, the darkroom device provided in the embodiment of this utility model includes a housing 10 and a door 20. The housing 10 has an opening 110, which includes a first opening segment 111 and a second opening segment 112 communicating with the first opening segment 111. The first opening segment 111 and the second opening segment 112 intersect, and the housing 10 is configured to place the testing device. The door 20 is connected to the housing 10 and is adapted to switch between a first position and a second position. In the first position, the door 20 opens the opening 110 to expose the first opening segment 111 and the second opening segment 112; in the second position, the door 20 closes the opening 110.

[0092] The darkroom device includes a housing 10 and a door 20. The housing 10 has an opening 110, and the door 20 can open or close the opening 110. Figure 11 As shown, the housing 10 is used to house the testing device 50 and the object under test 60. The housing 10 can be square, trapezoidal, polygonal, etc. For example, the housing 10 is a hollow square with an opening 110, and the shape of the door 20 matches the shape of the opening 110. The housing 10 includes a top, a bottom, and multiple sides connecting the top and bottom.

[0093] In some embodiments, the opening 110 extends from the top of the housing 10 to one side of the housing 10, i.e., the opening 110 is L-shaped. The opening 110 includes a first opening segment 111 and a second opening segment 112 that are connected. The first opening segment 111 is located at the top of the housing 10, and the second opening segment 112 is located at the side of the housing 10. The second opening segment 112 can extend to the bottom of the housing 10. The door 20 is L-shaped, and the first end of the door 20 can be connected to the top of the housing 10 via a rotating connector, which includes a pivot, a hinge, etc. When an upward external force is applied to the door 20, the door 20 can rotate upward to a first position, where the entire door 20 is located above the housing 10, and the first opening segment 111 and the second opening segment 112 are exposed.

[0094] The first opening section 111 is located at the top of the housing 10, and the second opening section 112 is located on the side of the housing 10. That is, the first opening section 111 and the second opening section 112 are located on two intersecting surfaces. The opening 110 is large, creating a sufficiently large operating space between the housing 10 and the door 20. Operators can place or remove the object 60 to be tested at this location. Operators can also inspect or repair the testing device 50 here, which improves operational convenience. Furthermore, operators can replace the testing device 50 here, allowing for testing of different types of objects 60 by changing to different testing devices 50, effectively improving the versatility of the darkroom device.

[0095] When a downward force is applied to the door 20, the door 20 can rotate downward to the second position, and the door 20 closes the opening 110, allowing the test object 60 inside the dark box device to be tested.

[0096] In an embodiment of this utility model, the housing 10 is provided with an opening 110, which includes a first opening segment 111 and a second opening segment 112 that are connected and intersecting. The door 20 can open or close the opening 110. The door 20 is in a first position. Since the first opening segment 111 and the second opening segment 112 are located on two intersecting surfaces, a large operating space is formed between the door 20 and the housing 10, which facilitates the replacement of the testing device 50, improves the versatility of the dark box device, and also facilitates the convenience of operation.

[0097] like Figure 1 and Figure 2As shown, in an optional embodiment, the housing 10 includes a base plate 11, a first frame 12, and a second frame 13. Two first frames 12 are disposed on one side of the base plate 11 and are arranged opposite to each other. One end of the second frame 13 is connected to one of the first frames 12, and the other end is connected to the other first frame 12. The door 20 includes a third frame 21 and a fourth frame 22. The third frame 21 is rotatably connected to the end of the second frame 13 away from the base plate 11; the fourth frame 22 is connected to the end of the third frame 21 away from the second frame 13. In the second position, the door 20 is closed by the third frame 21 covering the first opening section 111, and the fourth frame 22 covering the second opening section 112.

[0098] In some embodiments, the housing 10 is a square housing with an L-shaped opening 110 extending from the top of the housing 10 to one side. The housing 10 has a length direction, a width direction, and a height direction. The base plate 11 is a general-purpose optical base plate with multiple mounting holes for fixing the test device 50. The mounting holes can also be used to fix the test object 60. The housing 10 includes the base plate 11 and a U-shaped frame disposed on one side of the base plate 11. The U-shaped frame includes two first frames 12 and one second frame 13. The two first frames 12 are spaced apart along the length of the base plate 11, and the second frame 13 is located on the same side of the two first frames 12, sandwiched between the two first frames 12. The second frame 13 can be connected to the first frame 12 by screwing, snapping, or other means. Thus, the base plate 11, the two first frames 12, and the second frame 13 enclose a housing 10 with an L-shaped opening 110. The first opening segment 111 occupies the top area of ​​the housing 10, that is, the tops of the two first frames 12 and the top of the second frame 13 enclose and form a U-shaped first opening segment 111. The second opening segment 112 occupies the side area of ​​the housing 10, that is, the end of the two first frames 12 away from the second frame 13 and the end of the bottom plate 11 enclose and form a U-shaped second opening segment 112.

[0099] The door 20 includes a third frame 21 and a fourth frame 22 connected to each other, with the third frame 21 and the fourth frame 22 perpendicular to each other. The third frame 21 can be connected to the fourth frame 22 by means of screws, snap-fits, etc., or the third frame 21 and the fourth frame 22 can be integrally formed by bending. The length of the third frame 21 is adapted to the distance between the two first frames 12, and the width of the third frame 21 is adapted to the width dimension of the first frame 12, that is, the shape and size of the third frame 21 are adapted to the shape and size of the first opening segment 111. The length of the fourth frame 22 is adapted to the distance between the two first frames 12, and the width of the fourth frame 22 is adapted to the height dimension of the first frame 12, that is, the shape and size of the fourth frame 22 are adapted to the shape and size of the second opening segment 112.

[0100] The end of the third frame 21 furthest from the fourth frame 22 is rotatably connected to the top of the second frame 13. The third frame 21 can be rotatably connected to the second frame 13 via a hinge 15. The hinge 15 includes a spindle and two blades connected to the spindle; one blade connects to the top surface of the second frame 13, and the other blade connects to the top surface of the third frame 21. The number of hinges 15 can be one, two, or more; for example, the third frame 21 and the second frame 13 can be rotatably connected via two hinges 15. The connection between the third frame 21 and the second frame 13 via hinges 15 facilitates assembly.

[0101] In this embodiment of the invention, the box body 10 is assembled from a base plate 11 and three frames, and the box door 20 is assembled from two frames, which facilitates manufacturing. Applying an upward force to the box door 20 causes it to rotate to a first position. The third frame 21 and the fourth frame 22 are positioned above the first frame 12 and the second frame 13, and the fourth frame 22 has a suitable distance from the top surface of the box body 10. This creates a sufficiently large operating space between the box body 10 and the box door 20, which facilitates operation for the worker. Furthermore, when the box door 20 is open, the frame structure of the box body 10 ensures sufficient stability for the dark box device, guaranteeing safety during use.

[0102] like Figure 1 , Figure 2 and Figure 5 As shown, in an optional embodiment, the first frame 12 includes two first connecting rods 121 arranged opposite to each other, two second connecting rods 122 arranged opposite to each other, the two first connecting rods 121 and the two second connecting rods 122 are connected end to end to form a first frame structure with a first opening, a plurality of first connecting blocks 123, each first connecting block 123 having a plurality of connecting holes, the first connecting rods 121 and the second connecting rods 122 are connected through the first connecting blocks 123; a first sealing plate 124 is connected to the first frame structure and is used to seal the first opening.

[0103] The second frame 13 includes two third connecting rods 131 arranged opposite to each other. The two ends of the third connecting rods 131 are connected to the first connecting block 123. The two third connecting rods 131 and the two second connecting rods 122 are connected end to end to form a second frame structure with a second opening. The second sealing plate 132 is connected to the second frame structure and is used to seal the second opening.

[0104] For example, the first frame 12 is assembled from multiple connecting rods, multiple first connecting blocks 123, and a first sealing plate 124. The connecting rods can be made of profiles, including aluminum profiles, stainless steel profiles, plastic profiles, etc. The connecting rods can be square connecting rods, including four sides and two end faces. According to the usage requirements, profile parts of a first length and a second length are cut from the profiles, and the profile part of the first length is defined as the first connecting rod 121, and the profile part of the second length is defined as the second connecting rod 122.

[0105] Optionally, slots 120 are provided on all four sides of the connecting rod, and a threaded hole is formed in the middle area of ​​the connecting rod, the threaded hole penetrating through the two end faces of the connecting rod.

[0106] The first connecting block 123 has multiple connecting holes, for example, three connecting holes, which are perpendicular to each other in pairs. Any one of the connecting holes can be connected to the first connecting rod 121, and any one of the connecting holes can be connected to the second connecting rod 122. The first connecting block 123 can be a standard profile tee connector.

[0107] The housing 10 has a length direction, a width direction, and a height direction, defined as the length direction as the first direction, the width direction as the second direction, and the height direction as the third direction. Two first connecting rods 121 are arranged parallel to each other at intervals along the third direction, and two second connecting rods 122 are arranged parallel to each other at intervals along the second direction. One connecting hole of the first connecting block 123 is connected to the threaded hole of the first connecting rod 121 by a screw, and another connecting hole of the first connecting block 123 is connected to the threaded hole of the second connecting rod 122 by a screw. The first connecting block 123 is used to connect the first connecting rods 121 and the second connecting rods 122. Thus, the two first connecting rods 121, the two second connecting rods 122, and the four first connecting blocks 123 are assembled to form a first frame structure, and a first opening is formed on the inner side of the first frame structure.

[0108] In some embodiments, the first sealing plate 124 has a through hole at its edge, and the first connecting rod 121 and the second connecting rod 122 have threaded holes. Multiple through holes and multiple threaded holes correspond one-to-one, and screws pass through the through holes and threaded holes to connect the first sealing plate 124 to the first frame structure. The first sealing plate 124 can seal the first opening.

[0109] In some embodiments, slots 120 are provided on the side of the first connecting rod 121 and the side of the second connecting rod 122. The width of the slot 120 is adapted to the thickness of the first sealing plate 124. The circumferential edge of the first sealing plate 124 is inserted into the slots 120 of the first connecting rod 121 and the second connecting rod 122 to realize the connection between the first sealing plate 124 and the first frame structure.

[0110] According to usage requirements, a third length of profile component is cut from the profile, and this third length profile component is defined as the third connecting rod 131. Two third connecting rods 131 are arranged parallel to each other at intervals along a third direction. One end of the third connecting rod 131 is connected to a connecting hole of a first connecting block 123 on one first frame 12, and the other end of the third connecting rod 131 is connected to a connecting hole of a first connecting block 123 on another first frame 12. Thus, the two third connecting rods 131, the two second connecting rods 122, and the four first connecting blocks 123 are assembled to form a second frame structure, and a second through-hole is formed on the inner side of the second frame structure.

[0111] In some embodiments, slots 120 are provided on the sides of the second connecting rod 122 and the third connecting rod 131. The width of the slots 120 is adapted to the thickness of the second sealing plate 132. The circumferential edge of the second sealing plate 132 is inserted into the slots 120 of the second connecting rod 122 and the third connecting rod 131, thereby connecting the second sealing plate 132 and the second frame structure. The second sealing plate 132 can seal the second opening.

[0112] It is understandable that the first sealing plate 124 and the second sealing plate 132 are made of opaque materials. The first sealing plate 124 and the second sealing plate 132 can be made of thin aluminum alloy plates, cardboard, or other lightweight materials, which is beneficial to the weight reduction of the enclosure 10 and also facilitates processing and manufacturing.

[0113] The first and second frame structures are assembled from multiple connecting rods and multiple first connecting blocks 123, which is convenient to assemble and has low manufacturing cost. According to the usage requirements, the first connecting rod 121, the second connecting rod 122, and the third connecting rod 131 are cut to appropriate lengths, which facilitates flexible adjustment of the dimensions of the first and second frame structures.

[0114] In this embodiment of the invention, the first frame 12 is assembled from a first frame structure and a first sealing plate 124, and the second frame 13 is assembled from a second frame structure and a second sealing plate 132. The first sealing plate 124 and the second sealing plate 132 can be made of thin and light materials according to usage requirements. The box 10 is quick to assemble, structurally stable, and lightweight, making it easy to manufacture and transport.

[0115] like Figure 1 , Figure 2 , Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, in an optional embodiment, the third frame 21 includes two fourth connecting rods 211 arranged opposite to each other; two fifth connecting rods 212 arranged opposite to each other, the two fourth connecting rods 211 and the two fifth connecting rods 212 being connected end to end to form a third frame structure with a third opening; a plurality of second connecting blocks 213, the second connecting blocks 213 having a plurality of connecting holes, the fourth connecting rods 211 and the fifth connecting rods 212 being connected through the second connecting blocks 213; and a third sealing plate 214, connected to the third frame structure, for sealing the third opening.

[0116] The fourth frame 22 includes two sixth connecting rods 221 arranged opposite to each other; a seventh connecting rod 222 is arranged opposite to the fifth connecting rod 212, and the two sixth connecting rods 221, the fifth connecting rod 212 and the seventh connecting rod 222 are connected end to end to form a fourth frame structure with a fourth opening; and a fourth sealing plate 223 is connected to the fourth frame structure for sealing the fourth opening.

[0117] For example, the third frame 21 is assembled from multiple connecting rods, multiple second connecting blocks 213, and a third sealing plate 214. According to usage requirements, profile parts of a fourth and fifth length are cut from the profile, and the profile part of the fourth length is defined as the fourth connecting rod 211, and the profile part of the fifth length is defined as the fifth connecting rod 212.

[0118] The second connecting block 213 has multiple connecting holes, for example, three connecting holes, which are perpendicular to each other in pairs. Any one of the connecting holes can be connected to the fourth connecting rod 211, and any one of the connecting holes can be connected to the fifth connecting rod 212. The second connecting block 213 can be a standard profile tee connector.

[0119] Two fourth connecting rods 211 are arranged parallel to each other at intervals, and two fifth connecting rods 212 are arranged parallel to each other at intervals. After the fourth connecting rods 211 and the fifth connecting rods 212 are assembled, one connecting hole of the second connecting block 213 is connected to the threaded hole of the fourth connecting rod 211 by a screw, and another connecting hole of the second connecting block 213 is connected to the threaded hole of the fifth connecting rod 212 by a screw. The fourth connecting rods 211 and the fifth connecting rods 212 are connected through the second connecting block 213. Thus, the two fourth connecting rods 211, the two fifth connecting rods 212, and the four second connecting blocks 213 are assembled to form a third frame structure, and a third through-hole is formed on the inner side of the third frame structure.

[0120] In some embodiments, slots 120 are provided on the sides of the fourth connecting rod 211 and the fifth connecting rod 212. The width of the slots 120 is adapted to the thickness of the third sealing plate 214. The circumferential edge of the third sealing plate 214 is inserted into the slots 120 of the fourth connecting rod 211 and the fifth connecting rod 212, thereby connecting the third sealing plate 214 and the third frame structure. The third sealing plate 214 can seal the third opening.

[0121] Two sixth connecting rods 221 are arranged parallel to each other at intervals, and each of the six sixth connecting rods 221 is connected to one of the two fourth connecting rods 211. One connecting hole of the second connecting block 213 is connected to the threaded hole of the fourth connecting rod 211 by a screw, one connecting hole of the second connecting block 213 is connected to the threaded hole of the fifth connecting rod 212 by a screw, and one connecting hole of the second connecting block 213 is connected to the threaded hole of the sixth connecting rod 221 by a screw, thus connecting the fourth connecting rod 211, the fifth connecting rod 212, and the sixth connecting rod 221. The seventh connecting rod 222 is arranged parallel to the fifth connecting rod 212 at intervals, and both ends of the seventh connecting rod 222 are connected to the sixth connecting rod 221 through the second connecting block 213. Thus, the two sixth connecting rods 221, the fifth connecting rod 212, the seventh connecting rod 222, and the four second connecting blocks 213 are assembled to form the fourth frame structure, and the fourth through-hole is formed on the inner side of the fourth frame structure.

[0122] In some embodiments, slots 120 are provided on the sides of the fifth connecting rod 212, the sixth connecting rod 221, and the seventh connecting rod 222. The width of the slots 120 is adapted to the thickness of the fourth sealing plate 223. The circumferential edge of the fourth sealing plate 223 is inserted into the slots 120 of the fifth connecting rod 212, the sixth connecting rod 221, and the seventh connecting rod 222, thereby connecting the fourth sealing plate 223 and the fourth frame structure. The fourth sealing plate 223 can seal the fourth opening.

[0123] Understandably, the third sealing plate 214 and the fourth sealing plate 223 are made of opaque materials. The third sealing plate 214 and the fourth sealing plate 223 can be made of thin aluminum alloy plates, cardboard, or other lightweight materials, which is beneficial for the lightweight design of the door 20 and also facilitates processing and manufacturing.

[0124] The third and fourth frame structures are assembled from multiple connecting rods and multiple second connecting blocks 213, making assembly convenient. According to usage requirements, the fourth connecting rod 211, fifth connecting rod 212, sixth connecting rod 221, and seventh connecting rod 222 can be cut to appropriate lengths, facilitating flexible adjustment of the dimensions of the third and fourth frame structures.

[0125] In this embodiment of the invention, the third frame 21 is assembled from the third frame structure and the third sealing plate 214, and the fourth frame 22 is assembled from the fourth frame structure and the fourth sealing plate 223. The third sealing plate 214 and the fourth sealing plate 223 can be made of thin and lightweight materials according to usage requirements. The door 20 is quick to assemble and lightweight, which facilitates easy opening and closing of the door 20.

[0126] like Figure 7 and Figure 8 As shown, in an optional embodiment, the darkroom device further includes a plurality of sealing gaskets 41. Sealing gaskets 41 are provided at the positions where the first connecting rod 121 and the first connecting block 123 are connected, sealing gaskets 41 are provided at the positions where the second connecting rod 122 and the first connecting block 123 are connected, and sealing gaskets 41 are provided at the positions where the third connecting rod 131 and the first connecting block 123 are connected.

[0127] A sealing gasket 41 is provided at the position where the fourth connecting rod 211 connects to the second connecting block 213; a sealing gasket 41 is provided at the position where the fifth connecting rod 212 connects to the second connecting block 213; a sealing gasket 41 is provided at the position where the sixth connecting rod 221 connects to the second connecting block 213; and a sealing gasket 41 is provided at the position where the seventh connecting rod 222 connects to the second connecting block 213.

[0128] Specifically, a sealing gasket 41 is sandwiched between the end face of the first connecting rod 121 and the end face of the first connecting block 123. A screw passes through the connecting hole of the first connecting block 123 and the sealing gasket 41, and is screwed into the threaded hole of the first connecting rod 121. The connection methods of the second connecting rod 122, the first connecting block 123 and the sealing gasket 41, and the connection methods of the third connecting rod 131, the first connecting block 123 and the sealing gasket 41 are the same as those of the first connecting rod 121, the first connecting block 123 and the sealing gasket 41.

[0129] A sealing gasket 41 is sandwiched between the end face of the fourth connecting rod 211 and the end face of the second connecting block 213. A screw passes through the connecting hole of the second connecting block 213 and the sealing gasket 41, and is screwed into the threaded hole of the fourth connecting rod 211. The connection methods of the fifth connecting rod 212, the second connecting block 213 and the sealing gasket 41, the sixth connecting rod 221, the second connecting block 213 and the sealing gasket 41, and the seventh connecting rod 222, the second connecting block 213 and the sealing gasket 41 are the same as those of the fourth connecting rod 211, the second connecting block 213 and the sealing gasket 41.

[0130] The sealing gasket 41 can be made of flexible materials such as rubber or silicone. Sealing gaskets 41 are sandwiched at the positions where the first connecting rod 121, the second connecting rod 122, and the third connecting rod 131 are assembled with the first connecting block 123. Sealing gaskets 41 are also sandwiched at the positions where the fourth connecting rod 211, the fifth connecting rod 212, the sixth connecting rod 221, and the seventh connecting rod 222 are assembled with the second connecting block 213. The sealing gasket 41 can compensate for unevenness of the end faces caused by processing and installation errors, fill the gap between the two end faces, and effectively prevent light leakage at the connection end faces.

[0131] In the embodiments of this utility model, sealing gaskets 41 are provided at the positions where the connecting rod and the connecting block are assembled, which effectively improves the sealing performance of the dark box device and thus helps to ensure the accuracy of the test results.

[0132] like Figure 7 , Figure 8 and Figure 9 As shown, in an optional embodiment, the dark box device further includes a plurality of first sealing strips 42. The sides of the first connecting rod 121, the second connecting rod 122, and the third connecting rod 131 are provided with slots 120, and at least a portion of the first sealing strip 42 is embedded in the slot 120; a first sealing plate 124 is inserted into the slot 120 at the first frame structure and abuts against the first sealing strip 42; a second sealing plate 132 is inserted into the slot 120 at the second frame structure and abuts against the first sealing strip 42.

[0133] The fourth connecting rod 211, the fifth connecting rod 212, the sixth connecting rod 221, and the seventh connecting rod 222 are provided with slots 120 on their sides. The third sealing plate 214 is inserted into the slot 120 at the third frame structure and abuts against the first sealing strip 42; the fourth sealing plate 223 is inserted into the slot 120 at the fourth frame structure and abuts against the first sealing strip 42.

[0134] For ease of description, the first connecting rod 121, the second connecting rod 122, the third connecting rod 131, the fourth connecting rod 211, the fifth connecting rod 212, the sixth connecting rod 221, and the seventh connecting rod 222 are collectively referred to as connecting rods, and the first sealing plate 124, the second sealing plate 132, the third sealing plate 214, and the fourth sealing plate 223 are collectively referred to as sealing plates.

[0135] Optionally, slots 120 are provided on all four sides of the connecting rod. In order to facilitate the smooth insertion of the sealing plate into the slots 120 of the connecting rod, the width of the slot 120 is usually slightly larger than the thickness of the sealing plate. As a result, gaps will inevitably appear at the connection between the sealing plate and the slot 120.

[0136] The first sealing strip 42 is inserted into the slot 120, at least a portion of the first sealing strip 42 is embedded in the slot 120, and then the sealing plate is inserted. The end face and at least a portion of the surface of the sealing plate abut against the first sealing strip 42, which can improve the sealing performance at the connection between the sealing plate and the slot 120.

[0137] First sealing strips 42 are embedded in the slots 120 of the first connecting rod 121 and the second connecting rod 122 of the first frame structure to improve the sealing performance at the connection between the first sealing plate 124 and the first frame structure. Similarly, first sealing strips 42 are embedded in the slots 120 of the second connecting rod 122 and the third connecting rod 131 of the second frame structure to improve the sealing performance at the connection between the second sealing plate 132 and the second frame structure.

[0138] First sealing strips 42 are embedded in the slots 120 of the fourth connecting rod 211 and the fifth connecting rod 212 of the third frame structure to improve the sealing performance at the connection between the third sealing plate 214 and the third frame structure. First sealing strips 42 are also embedded in the slots 120 of the fifth connecting rod 212, the sixth connecting rod 221, and the seventh connecting rod 222 of the fourth frame structure to improve the sealing performance at the connection between the fourth sealing plate 223 and the fourth frame structure.

[0139] A first sealing strip 42 is embedded in the slot 120 of the connecting rod. The sealing plate is inserted into the slot 120. The first sealing strip 42 can fill the gap at the connection between the sealing plate and the slot 120, which helps to further improve the sealing performance of the dark box device and thus ensure the accuracy of the test results.

[0140] like Figure 8 and Figure 9 As shown, in an optional embodiment, the first sealing strip 42 includes a bottom sealing body 421 and two side sealing bodies 422, which are disposed on opposite sides of the bottom sealing body 421. The top of the side sealing body 422 is bent outward to form an overlapping portion 4221, which is adapted to overlap the slot 120; the inner wall surface of the side sealing body 422 is provided with an abutting portion 4222, which is adapted to abut against the surface of the sealing plate.

[0141] Specifically, the first sealing strip 42 has a U-shaped cross-section and consists of a bottom sealing body 421 and two side sealing bodies 422 connected to both sides of the bottom sealing body 421. The top of the side sealing body 422 bends outward to form an overlapping portion 4221, with a bending angle of up to 90 degrees. The top of the slot 120 of the connecting rod has two L-shaped steps, and the two overlapping portions 4221 overlap the two steps respectively, ensuring that the first sealing strip 42 is securely embedded in the slot 120. The inner wall surface of the side sealing body 422 has a protruding abutment portion 4222, which is inclined towards the bottom sealing body 421. The distance between the two abutment portions 4222 of the two side sealing bodies 422 is adapted to the thickness of the sealing plate.

[0142] The first sealing strip 42 can be made of flexible materials such as rubber or silicone. Figure 8 and Figure 9 As shown, during the insertion of the fourth sealing plate 223 between the two abutting portions 4222, the two abutting portions 4222 tend to expand outwards, ensuring that the fourth sealing plate 223 can be smoothly inserted between the two abutting portions 4222. After the fourth sealing plate 223 is inserted into place, the end face of the fourth sealing plate 223 abuts against the bottom sealing body 421, and the two abutting portions 4222 tend to retract inwards, so that the two abutting portions 4222 can abut against the two surfaces of the fourth sealing plate 223. Thus, the first sealing strip 42 effectively fills the gap between the sealing plate and the slot 120, further improving the sealing performance of the dark box device.

[0143] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment, the dark box device further includes a support member 30, which includes a first hinge seat 31, a second hinge seat 32, and a telescopic member 33. The first hinge seat 31 is disposed on the first frame 12; the second hinge seat 32 is disposed on the third frame 21 and located at the end of the third frame 21 away from the fourth frame 22. The telescopic member 33 includes a fixed part 331 and a telescopic part 333 connected to each other. One of the fixed part 331 and the telescopic part 333 is hinged to the first hinge seat 31, and the other is hinged to the second hinge seat 32. The telescopic member 33 is adapted to extend and retract under the action of external force so that the box door 20 is in a first position or a second position.

[0144] In some embodiments, the support component 30 includes a telescopic component such as a cylinder, hydraulic cylinder, or electric actuator. For example, the support component 30 includes a cylinder, the fixed end of which is hinged to the housing 10, and the piston rod of the cylinder is hinged to the door 20. During the upward rotation of the door 20, the piston rod extends, and when the door 20 rotates upward to the first position, the piston rod extends to the target length, thus providing support for the door 20.

[0145] In some embodiments, the support member 30 includes a first hinge seat 31, a second hinge seat 32, and a telescopic member 33. The number of first hinge seats 31 and the number of second hinge seats 32 are the same. For example, there are two first hinge seats 31 and two second hinge seats 32. The first hinge seats 31 are located at the top of the first frame 12, and the second hinge seats 32 are located at the ends of the third frame 21, with each of the two second hinge seats 32 corresponding to one of the two first hinge seats 31.

[0146] The telescopic component 33 includes a pneumatic rod, which comprises a cylinder and a piston rod. The cylinder is a fixed part 331, and the piston rod is a telescopic part 333. The cylinder has a first connecting seat 332 at its end, and the piston rod has a second connecting seat 334 at its end. In some embodiments, the first connecting seat 332 can be a U-shaped connecting seat, comprising two opposing first sidewalls with shaft holes on each sidewall. The first hinge seat 31 can be L-shaped, comprising a first connecting plate 311 and a second connecting plate 312 perpendicular to each other. The first connecting plate 311 is connected to the inner side of the first connecting rod 121, and the second connecting plate 312 has shaft holes. The second connecting plate 312 is located between the two first sidewalls. A rotating shaft passes through the shaft holes on the first sidewalls and the second connecting plate 312. Nuts are screwed onto both ends of the rotating shaft to achieve the hinge connection between the cylinder and the first hinge seat 31.

[0147] In some embodiments, the second connecting seat 334 can be a U-shaped connecting seat, and the second connecting seat 334 includes two opposing second sidewalls, each with a shaft hole. The second hinge seat 32 can be L-shaped, and the second hinge seat 32 includes a third connecting plate 321 and a fourth connecting plate 322 that are perpendicular to each other. The third connecting plate 321 is connected to the inner side of the fourth connecting rod 211, and the fourth connecting plate 322 has a shaft hole. The rotating shaft passes through the shaft hole on the second sidewall and the shaft hole on the fourth connecting plate 322, and nuts are screwed onto both ends of the rotating shaft to achieve the hinge connection between the piston rod and the second hinge seat 32.

[0148] Thus, one end of the pneumatic rod is hinged to the first hinge seat 31, and the other end is hinged to the second hinge seat 32. Applying an upward force to the door 20 causes the piston rod to extend until it stops extending, at which point the door 20 rotates to the first position. Supported by the piston rod, the door 20 remains stably in the first position. Applying a downward force to the door 20 causes the piston rod to retract until it stops retracting, at which point the door 20 rotates to the second position.

[0149] When the telescopic component 33 is extended, it effectively supports the door 20. The support component 30 supports the door 20, ensuring that the door 20 is stably stopped in the first position and preventing the door 20 from closing due to accidental situations. At this time, the darkroom device is in the open state, eliminating the need for multiple operators. A single operator can place the object 60 into the darkroom device, remove the tested object 60, inspect or repair the testing device 50, or replace the testing device 50, etc. The support component 30 supports the door 20, ensuring safety, reliability, and ease of operation for the operator.

[0150] When the telescopic component 33 is retracted, the door 20 can be stably positioned in the second position. Furthermore, when the telescopic component 33 is retracted, it occupies little space and effectively avoids collisions with other components inside the dark box device.

[0151] In the embodiments of this utility model, one end of the telescopic member 33 is hinged to the box body 10, and the other end of the telescopic member 33 is hinged to the box door 20. The telescopic member 33 can extend and retract to make the box door 20 stably in the first position or the second position. The structure is simple and occupies little space. In addition, it can ensure the safety, reliability and convenience of operation for operators during use.

[0152] like Figure 2 , Figure 5 and Figure 6 As shown, in an optional embodiment, the housing 10 further includes an eighth connecting rod 14, which is disposed on the bottom plate 11. Both ends of the eighth connecting rod 14 are connected to two first frames 12 respectively, and a door lock seat 16 is provided on one side of the eighth connecting rod 14. The housing door 20 also includes a door lock 23, which is disposed on the fourth frame 22 and opposite to the door lock seat 16. In this configuration, the housing door 20 is in the second position, and the door lock 23 and door lock seat 16 are in a locked state.

[0153] Specifically, the base plate 11 is also provided with an eighth connecting rod 14, which is spaced apart from the third connecting rod 131 on the base plate 11. The two ends of the eighth connecting rod 14 are respectively connected to two first connecting blocks 123. A door lock seat 16 is provided on the outer side of the eighth connecting rod 14, and the door lock seat 16 is provided with a receiving cavity for accommodating the door lock 23.

[0154] A door lock 23 is provided on the outer surface of the seventh connecting rod 222, and the door lock 23 matches the door lock seat 16. The number of door locks 23 and door lock seats 16 is set according to actual needs. For example, there are two door locks 23 and two door lock seats 16, with the two door locks 23 spaced apart on the seventh connecting rod 222 and the two door lock seats 16 spaced apart on the eighth connecting rod 14.

[0155] When the chamber door 20 is rotated to the second position, the seventh connecting rod 222 and the eighth connecting rod 14 are engaged, the door lock 23 is inserted into the door lock seat 16, and the dark box device is in a locked state to prevent the chamber door 20 from being opened accidentally during the test, thus ensuring the safety of the test process and the accuracy of the test results.

[0156] Optionally, the door lock 23 has an arc-shaped guide portion 231 on the side facing the door lock seat 16, which facilitates the smooth sliding of the door lock 23 into the door lock seat 16.

[0157] Optionally, the door 20 is also provided with a handle 26, which can be located between the two door locks 23. Applying an upward lifting force or a downward pulling force to the door 20 via the handle 26 facilitates the opening or closing of the door 20, thus improving operational convenience.

[0158] Optionally, the base plate 11 is also provided with handles 17, for example, along the length of the base plate 11, each end of the base plate 11 is provided with a handle 17, so as to facilitate the handling of the dark box device.

[0159] like Figure 5 , Figure 8 and Figure 9 As shown, in an optional embodiment, the door 20 further includes a pressure plate 24 and a second sealing strip 25. The pressure plate 24 is connected to the outside of the third frame 21 and the fourth frame 22, and the door lock 23 is located on one side of the pressure plate 24. The second sealing strip 25 is located on the other side of the pressure plate 24 and abuts against the edges of the third frame 21 and the fourth frame 22. The door 20 is in a second position, and the second sealing strip 25 abuts against the edges of the first frame 12 and the eighth connecting rod 14 to seal the gap between the box body 10 and the door 20.

[0160] Specifically, pressure plate 24 is located on the outer surfaces of the two fourth connecting rods 211, the two sixth connecting rods 221, and the seventh connecting rod 222. Pressure plate 24 can be connected to the connecting rods by screwing. Door lock 23 and handle 26 can be installed on the outer surface of pressure plate 24.

[0161] The second sealing strip 25 is disposed on the inner side of the pressure plate 24, and extends along the extending direction of the pressure plate 24. The second sealing strip 25 corresponding to the fourth connecting rod 211 has at least a portion abutting against the fourth connecting rod 211; the second sealing strip 25 corresponding to the sixth connecting rod 221 has at least a portion abutting against the sixth connecting rod 221; and the second sealing strip 25 corresponding to the seventh connecting rod 222 has at least a portion abutting against the seventh connecting rod 222. The second sealing strip 25 can be made of flexible materials such as rubber or silicone.

[0162] When the door 20 is rotated to the second position, the door lock 23 contacts the door lock seat 16 and slowly slides into the door lock seat 16. After the door lock 23 is locked with the door lock seat 16, the pressure plate 24 presses and deforms the second sealing strip 25. The second sealing strip 25 can effectively seal the gap between the seventh connecting rod 222 and the eighth connecting rod 14, the gap between the sixth connecting rod 221 and the second connecting rod 122, and the gap between the fourth connecting rod 211 and the first connecting rod 121. That is, the second sealing strip 25 effectively seals the gap between the box body 10 and the door 20, further improving the sealing performance of the dark box device.

[0163] Optionally, the second sealing strip 25 includes a D-shaped sealing strip, that is, the cross-section of the second sealing strip 25 is D-shaped and the middle area of ​​the second sealing strip 25 is hollow. During the closing process of the box door 20, the second sealing strip 25 is suitable for large deformation under the pressure of the pressure plate 24, which increases the contact area between the second sealing strip 25 and the connecting rod, which is conducive to better sealing the gap between the box body 10 and the box door 20, and thus further improves the sealing performance of the dark box device.

[0164] like Figure 10 As shown, optionally, the darkroom devices can also be used in combination. For example, two darkroom devices can be combined along their length by simply replacing the bottom plate 11 of the housing 10 and removing the first sealing plate 124 at the joint of the two darkroom devices. Using two darkroom devices in combination increases the internal space, allowing for the placement of multiple testing devices 50, thereby enabling the simultaneous placement of multiple test objects 60 and improving testing efficiency. Furthermore, the housing 10 is suitable for accommodating testing devices 50 of various specifications, further enhancing the versatility of the darkroom devices. It is understood that three or more darkroom devices can also be used in combination.

[0165] like Figure 11 As shown, an embodiment of the present invention also provides a dark box testing system, which includes a dark box device and a testing device 50. The testing device 50 is detachably disposed inside the dark box device and is used to test the object under test 60.

[0166] As described above, the structure of the darkroom testing device includes a housing 10 and a door 20. The housing 10 has an opening 110, which includes an intersecting first opening segment 111 and a second opening segment 112. The door 20 can open or close the opening 110. In the first position, a sufficiently large operating space is formed between the housing 10 and the door 20. In this position, operators can place or remove the object 60 to be tested, and can also inspect or repair the testing device 50, which improves operational convenience. Furthermore, operators can easily replace the testing device 50 here, allowing for testing of different types of objects 60, effectively improving the versatility of the darkroom testing system and the ease of operation for operators.

[0167] The above description is merely a specific embodiment of this utility model, but the scope of protection of this application is not limited thereto. Any changes or substitutions made within the spirit and principles of this utility model should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
