The term "multiple" indicates a quantity of two or more. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0020] This application provides a tall, spacious ceiling-mounted stretch film light box, such as... Figure 1 As shown, the tall, high-ceilinged stretch film lightbox includes a door frame 1 and multiple opening and closing components 2. Exemplarily, Figure 1 The tall, openable ceiling-mounted stretch film lightbox shown has six opening and closing components 2.

[0021] The door frame 1 includes a main frame 11 and a secondary frame 12. The main frame 11 is parallel to the mounting surface and defines a plurality of mounting holes for mounting the opening and closing assembly 2; exemplarily, Figure 1 In the middle, the main frame 11 defines six mounting holes, and six opening and closing components 2 are respectively installed in the six mounting holes. The secondary frame 12 connects the main frame 11 and the mounting surface to form a closed space, which is used to install LED light strips, driver power supplies and wiring.

[0022] Specifically, the material of door frame 1 can be hot-dip galvanized square tubing.

[0023] Multiple opening and closing components 2 are respectively located in multiple mounting holes and connected to the main frame 11. Each opening and closing component 2 includes a door leaf 21, multiple hinges 22, and a locking mechanism 23; exemplarily, each opening and closing component 2 includes three hinges 22. The door leaf 21 is connected to the wall of the mounting hole via the multiple hinges 22; the locking mechanism 23 is operatively connected to the main frame 11 and configured to connect and disconnect the door leaf 21 when it is in the closed position.

[0024] When inspecting this tall, open-plan ceiling-mounted stretch light box, maintenance personnel use a lifting device to reach the working surface at height. They then operate the locking mechanism 23 of each opening / closing component 2. The locking mechanism 23 activates, disengaging the door panel 21 from the main frame 11. The personnel then open the door panel 21 and troubleshoot the LED light strip, driver power supply, or wiring. After completing the inspection, the personnel close the door panel 21 and operate the locking mechanism 23 again, reconnecting the door panel 21 to the main frame 11. Therefore, the maintenance of this tall, open-plan ceiling-mounted stretch light box does not require complete or partial disassembly, saving maintenance time. Furthermore, one maintenance personnel can complete the inspection, thus improving maintenance efficiency.

[0025] like Figure 6 As shown in this embodiment, the door leaf 21 includes a door leaf 21 frame, a plurality of reinforcing beams 212, and a mounting plate 213. One side of the wall of the door leaf 21 frame facing the mounting hole is connected to a plurality of hinges 22. The plurality of reinforcing beams 212 are located inside the door leaf 21 frame, and both ends of the plurality of reinforcing beams 212 are connected to the door leaf 21 frame. The mounting plate 213 is connected to the side of the door leaf 21 frame facing the enclosed space. A locking mechanism 23 is connected to the door leaf 21 frame.

[0026] When in use, the LED light strip is located within the enclosed space and installed on the inside of the mounting plate 213; the locking mechanism 23 can connect and disconnect the door leaf 21 frame in the closed position from the main frame 11. Multiple reinforcing beams 212 enhance the overall strength of the door leaf 21 and are able to support the mounting plate 213.

[0027] Specifically, the door leaf 21 frame is made of aluminum profile square tube, which makes the door leaf 21 frame less heavy, making it easier to open and close the door leaf 21 as a whole, and avoiding the door leaf 21 being too heavy and causing it to be difficult to open.

[0028] Furthermore, the mounting plate 213 includes a light-transmitting base layer 2131 and a transparent plaster layer 2132 stacked together; the light-transmitting base layer 2131 is connected to the side of the door frame 21 facing the enclosed space. The light generated by the LED light strip undergoes diffuse reflection when passing through the transparent plaster layer 2132 and the light-transmitting base layer 2131, enabling highly uniform illumination.

[0029] Specifically, the multiple reinforcing crossbeams 212 include multiple first crossbeams 2121 and multiple second crossbeams 2122. The multiple first crossbeams 2121 and multiple second crossbeams 2122 are arranged in parallel, with both ends of the multiple first crossbeams 2121 and the multiple second crossbeams 2122 connected to the door leaf 21 frame. The first crossbeams 2121 and second crossbeams 2122 are arranged alternately. The thickness of the first crossbeam 2121 is equal to the thickness of the door leaf 21 frame, and the thickness of the first crossbeam 2121 is twice the thickness of the second crossbeam 2122.

[0030] For example, the thickness of the first crossbeam 2121 and the thickness of the door leaf 21 frame are both 40mm, and the thickness of the second crossbeam 2122 is 20mm.

[0031] like Figure 1 and 5 As shown in the embodiment of this application, the opening and closing component 2 further includes a plurality of positioning stops 24, which are connected to the door leaf 21 and are used to abut against the edge of the mounting hole when the door leaf 21 is in the closed position.

[0032] When maintenance personnel rotate the door leaf 21 to the closed position, multiple positioning stops 24 connected to the door leaf 21 press against the main frame 11, preventing the door leaf 21 from continuing to rotate and keeping the door leaf 21 in the closed position. This makes it easier for maintenance personnel to operate the locking mechanism 23, so that the locking mechanism 23 connects the door leaf 21 to the main frame 11.

[0033] For example, the opening and closing component 2 also includes two positioning stops 24, which are spaced apart.

[0034] Specifically, Figure 5 The positioning stop 24 shown includes two baffles that are orthogonally connected. One baffle is connected to the door leaf 21 by welding, bolting or other means, and the other baffle extends out of the door leaf 21 and extends to the edge of the mounting hole.

[0035] Continue to refer to Figure 5 The opening and closing assembly 2 also includes a plurality of elastic pads 25, which are connected to the side of the main frame 11 away from the closed space and correspond to a plurality of positioning stops 24.

[0036] Multiple elastic pads 25 are used to buffer and dampen multiple positioning stops 24 respectively, to prevent the positioning stops 24 from directly colliding with the main frame 11 and damaging the door leaf 21 or the main frame 11, and also to reduce the noise caused by the maintenance of the Gundam space ceiling soft film light box.

[0037] For example, the opening and closing assembly 2 also includes two positioning stops 24 and two elastic pads 25. The two positioning stops 24 are spaced apart, and the two elastic pads 25 are connected to the side of the main frame 11 facing away from the closed space and correspond to the two positioning stops 24 respectively.

[0038] It should be noted that among the multiple elastic pads 25 in two adjacent opening and closing components 2, two elastic pads 25 located at adjacent positions can be connected to form an integral structure.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown in the embodiment of this application, the locking mechanism 23 includes a base 231, a slider 232, a plug rod 233, and a spring 234.

[0040] The base 231 is connected to the door leaf 21. For example, as shown... Figure 2 and Figure 3 As shown, the base 231 has multiple through holes, and the corresponding position of the door leaf 21 has a threaded hole. Multiple bolts pass through the multiple through holes on the base 231 and are threadedly connected to the multiple threaded holes on the door leaf 21, thereby realizing the connection between the base 231 and the door leaf 21.

[0041] The slider 232 is slidably connected to the base 231 along a first direction. The slider 232 has an inclined surface 2321, and a groove 2322 is provided on the inclined surface 2321. Specifically, the first direction is... Figure 2 and Figure 3 The arrow direction is set on the slider 232. By operating the slider 232, the maintenance personnel can make the slider 232 slide in the first direction, thereby connecting or disconnecting the door leaf 21 from the main frame 11.

[0042] The insertion rod 233 is slidably connected to the base 231 along a second direction orthogonal to the first direction. The insertion rod 233 has a first end and a second end, with the first end abutting against the inclined surface 2321. Through holes are provided at positions corresponding to the insertion rod 233 on the door leaf 21 and the main frame 11, allowing the insertion rod 233 to pass through. When the slider 232 is operated to slide along the first direction, the insertion rod 233 slides under the drive of the inclined surface 2321, causing the second end of the insertion rod 233 to extend out of the door leaf 21 and into the main frame 11. When the first end of the insertion rod 233 enters the groove 2322, the positions of the slider 232 and the insertion rod 233 are fixed.

[0043] The two ends of the spring 234 are connected to the insert rod 233 and the base 231 respectively, and are configured to apply a spring force to the insert rod 233 along the axis of the insert rod 233 and pointing towards the inclined plane 2321, for pulling the insert rod 233 and causing the insert rod 233 to retract from the main frame 11.

[0044] The aforementioned locking mechanism 23 is easy to operate. Maintenance personnel can control the movement of the insertion rod 233 by sliding the slider 232, thereby connecting and disconnecting the door leaf 21 from the main frame 11. When the insertion rod 233 extends into the main frame 11, connecting the door leaf 21 to the main frame 11, one end of the insertion rod 233 is located within the groove 2322. The inner wall of the groove 2322 fixes the position of the insertion rod 233, thus locking its position. When it is necessary for the insertion rod 233 to retract from the main frame 11, the maintenance personnel operate the slider 232 to slide, causing one end of the insertion rod 233 to move out of the groove 2322 and re-apply to the inclined surface 2321. As the slider 232 slides, the insertion rod 233 gradually retracts from the main frame 11 under the action of the spring 234.
