[0034] See also Figure 1-7 As shown, the utility model provides a technical solution for a light box that is easy to replace a UV soft film: a light box that is easy to replace a UV soft film, comprising a shell 1 and a lighting part 2 installed on the inner wall of the shell 1, a sleeve frame 3 is movably installed at the open end of the shell 1, a positioning component 4 is installed on the outside of the sleeve frame 3, and a displacement component 5 is installed between one side of the sleeve frame 3 and the shell 1. The positioning assembly 4 includes a pressing block 401, a permanent magnet 402 and a positioning pin 403. The pressing block 401 is movably mounted on one side of the bevel of the outer edge of the sleeve frame 3. A bevel matching the bevel of the sleeve frame 3 is provided on one side of the pressing block 401. The edges around the UV soft film are placed between the bevel of the pressing block 401 and the bevel of the sleeve frame 3. The permanent magnet 402 is embedded in the pressing block 401 and the sleeve frame 3 to ensure the suction of the pressing block 401 and the sleeve frame 3. The positioning pin 403 is provided at one end of the pressing block 401 to match the hole on the outer edge of the sleeve frame 3. The positioning pin 403 is used to further fix the UV soft film to prevent the soft film from moving after installation, and can strengthen the connection strength between the pressing block 401 and the sleeve frame 3. When the UV soft film needs to be replaced, the sleeve frame 3 is first moved out of the housing 1 by the displacement assembly 5, and then the magnetic force of the permanent magnet 402 is overcome, and the pressing block 401 around the sleeve frame 3 is manually removed. At this time, the previously installed UV soft film can be taken out, and then a new soft film can be installed. The staff aligns the upper edge of the new soft film with the sleeve frame 3, folds the excess film material to the rear of the sleeve frame 3, and the film material at the folded part is as close to the oblique mouth of the sleeve frame 3 as possible. Then, the pressing block 401 is manually placed on the top of the sleeve frame 3. The pressing block 401 and the sleeve frame 3 are attracted by the permanent magnet 402, and the positioning pin 403 passes through the soft film to position the upper end of the soft film. Then, the left and right sides of the soft film are folded and positioned with the sleeve frame 3 in the same way. Then, the bottom of the soft film is folded and positioned with the sleeve frame 3. Finally, the sleeve frame 3 is retracted into the shell 1 through the displacement component 5, and the replaced UV soft film is parallel to the surface of the shell. Through the positioning component 4, the UV soft film is quickly positioned on the sleeve frame 3 and the UV soft film that needs to be replaced is quickly removed from the sleeve frame 3. The overall operation is simple and convenient, the aesthetics is high, the replacement efficiency of the UV soft film and the service life of the light box are improved, and it is more in line with the actual use needs of current enterprises.

[0035] The displacement assembly 5 includes a sleeve 501, a limit groove 503 and a screw 505. The sleeve 501 is symmetrically mounted on the inner side of the housing 1. A slide bar 502 is mounted on one side of the housing frame 3 located inside the housing 1. One end of the slide bar 502 is slidably connected to the sleeve 501. The limit groove 503 is provided on the shell wall of the housing 1 and is located on the back side of the sleeve 501. A baffle 504 is slidably connected in the limit groove 503. The screw 505 passes through the hole on the shell of the housing 1 and is threadedly connected to the slide bar 502. One end of the screw 505 away from the slide bar 502 is rotatably connected to a folding rod 506. The end of the folding rod 506 is spherically processed to prevent the slide bar 502 from sliding forward out of the sleeve 501. When the sleeve frame 3 needs to be moved, the baffle plate 504 on the upper side of the shell 1 is manually pushed to the upper side of the limit groove 503, and then the folding rod 506 is rotated and erected, and a certain thrust is applied to the direction of the slide bar 502, so that the front folded part of the folding rod 506 enters the hole on the shell body of the shell 1. At this time, the folding rod 506 is in a horizontal state and will not fall. Then, the above operation is repeated for the remaining folding rods 506 above and below the shell 1 in turn, so that all the folding rods 506 are in a horizontal state. At this time, each folding rod 506 can be further pushed until the sleeve frame 3 is completely moved to the outside of the shell 1, and the soft film can be replaced. When the sleeve frame 3 needs to be retracted, the folding rods 506 are pulled backwards in turn, and each folding rod 506 is pulled several times until the sleeve frame 3 is completely in the shell 1, and the folding rod 506 can be bent into the limit groove 503. The displacement assembly 5 is used to realize the quick separation and merging of the sleeve frame 3 and the housing 1 , and all operations can be completed without disassembling the light box, thereby further improving the efficiency of UV soft film replacement and saving construction time.

[0036] A water retaining strip 6 for blocking rainwater is installed at the edge of the sleeve frame 3 located outside the shell 1 . The water retaining strip 6 is made of soft rubber material and can prevent rainwater from leaking into the shell 1 .

[0037] A transparent acrylic plate 7 is embedded on one side of the sleeve frame 3. The acrylic plate 7 is both light-transmissive and can ensure the support of the soft film.

[0038] A plurality of positioning buckles 8 are installed at the outer edge of the housing 1 , and the positioning buckles 8 can be used to fix the light box to the wall.

[0039] The number of the sliding sleeves 501 and the sliding rods 502 is 6, and the 6 sliding sleeves 501 and the sliding rods 502 are symmetrically arranged in the light box, which can meet the normal guidance requirements when the sleeve frame 3 enters and exits the housing 1.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
