[0021] An embodiment of the present utility model discloses a quick-change lighting device, which is applied to a refrigerated container.

[0022] Refer to Figure 1 , the top plate of the refrigerated container includes an inner top plate 3, an outer top plate 1, and a thermal insulation foam layer 2 between the inner top plate 3 and the outer top plate 1. The lighting device includes a lamp 5, a lamp box 4, and a support frame 6. The outer edge 41 of the opening of the lamp box 4 is fixedly connected to the inner top plate 3 by rivets 81, and the outer edge 41 of the opening is located on the side of the inner top plate 3 facing the outer top plate 1. The inner top plate 3 is provided with a notch to communicate the inner space of the lamp box 4 with the inner space of the box body, facilitating the lamp 5 to illuminate the inner space of the box body.

[0023] The bottom view of the opening of the lamp box 4 is square. Combining Figure 1 and Figure 2 , Figure 1 and Figure 2 are cross-sectional views from the perspective of the front view and the left view respectively, that is, a support frame 6 is provided along each side of the square opening, and each support frame 6 is detachably fixed to the side of the inner top plate 3 facing the box body space. For convenient installation and fixation, each support frame 6 is located in the middle of the current side. Combining Figure 3 and Figure 4 , the support frame 6 is in a stepped shape, including a first tabletop 61 and a second tabletop 62. The first tabletop 61 is connected to the inner top plate 3 by rivets 81 or bolts 82. A sponge tape 91 is provided between the first tabletop 61 and the inner top plate 3, and the sponge tape 91 is fixed to the inner top plate 3. An installation space is formed between the second tabletop 62 and the inner top plate 3 to accommodate the periphery of the lamp 5, thereby installing the lamp 5. The second tabletop 62 provides support for the lamp 5, and the inner top plate 3 provides upper limit for the lamp 5, thereby clamping the lamp 5.

[0024] The periphery of the lamp 5 is evenly clamped between the support frame 6 and the inner top plate 3, and the main body part is placed in the inner space of the opening of the lamp box 4 to illuminate the inner space of the box body. A sealing strip 92 is provided between the support frame 6 and the lamp 5, and the sealing strip 92 is fixed to the side where the support frame 6 contacts the lamp 5 to achieve sealing and prevent water vapor from entering the inside of the lamp box 4.

[0025] For the convenient and quick disassembly and assembly of the lamp 5, among the four support frames 6, two adjacent support frames 6 are movable supports 6b, and the remaining two are fixed supports 6a. The fixed support 6a is fixedly connected to the inner top plate 3 and the outer edge 41 of the opening by rivets 81. When disassembling and assembling the lamp 5 later, the fixed support 6a is not moved, that is, the rivets 81 at this place are not disassembled, thus avoiding the disassembly and assembly problems such as slipping nails, empty rivets, and repeated caulking mentioned in the background art. The movable support 6b is connected to the top plate by bolts 82. For installing the movable support 6b, a bolt sleeve 7 is welded to the side of the outer edge 41 facing the outer top plate 1. Corresponding bolt holes are provided in both the outer edge 41 and the inner top plate 3. The movable support 6b is detachably connected to the top plate through the cooperation of the bolt 82 and the bolt sleeve 7. Refer to Figure 5and Figure 6 When the lamp 5 needs to be disassembled, the position of the movable support 6 b can be adjusted by operating the bolt 82 , and the movable support 6 b can be turned to be free from the restriction and support on the edge of the lamp 5 by the bolt 82 .

[0026] If the opening of the lamp box 4 is circular or has other symmetrical structures when viewed from above, among the evenly distributed support frames 6, only adjacent and at least half of the support frames 6 need to be designed as movable supports 6b, so that the restriction of at least half of the edge of the lamp 5 can be removed, thereby achieving quick replacement without riveting.

[0027] The utility model needs to first use double-sided tape to preliminarily position the opening outer edge 41 of the lamp box 4 with the bolt sleeve 7 on the side of the inner top plate 3 facing the outer top plate 1, and then inject material between the inner top plate 3 and the outer top plate 1 for foaming, and at the same time glue is applied at the installation support frame 6. After the foaming is completed, the countersunk rivets 81 are used to fix the opening outer edge 41, the inner top plate 3 and the fixed support 6a, and the bolts 82 are used to connect the movable support 6b to the top plate.

[0028] Based on the above structure, the quick-change process of the utility model is as follows: after loosening the bolt 82 with a wrench, turn the bolt 82, adjust the movable support 6b so that it does not interfere with the edge of the lamp 5, and then remove the damaged lamp 5 from the unrestricted side; when installing a new lamp 5, first place part of the edge of the new lamp 5 in the installation space formed by the fixed support 6a, adjust the position of the lamp 5, and then adjust the movable support 6b, tighten the bolt 82 to fix the movable support 6b in place, so that the remaining edge of the lamp 5 is supported and restricted, thereby installing the lamp 5 and ensuring the sealing.

[0029] In summary, the utility model can realize the rapid replacement of the lamp 5 with a new one when the lamp 5 is damaged, and when replacing the lamp 5, there is no need to use tools such as a gun drill, a rivet gun, or a glue gun. Only a common tool wrench or a torque wrench needs to be used to rotate the bolt 82 to change the position of the movable support 6b, and the lamp 5 can be replaced, thereby improving the replacement efficiency.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
