DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0024] like Figures 1 to 6 As shown, a luminous advertising light box that is easy to maintain includes a box body 1, and rotating rollers 2 are respectively provided on the left and right sides of the box body 1. The two rotating rollers 2 are arranged vertically and parallel and are respectively rotatably connected to the top and bottom of the inner wall of the box body 1. Sprockets 3 are fixedly installed on the bottom of the two rotating rollers 2 and are transmitted through chains 4. Conveyor belts 5 are sleeved on the two rotating rollers 2, and the conveyor belts 5 are used to fix advertising cloth 6. A light source assembly is provided on the box body 1 between the rotating rollers 2.

[0025] A box door 7 is provided on one side of the box body 1, and a driven wheel 8 is fixedly installed on the rotating roller 2 on one side of the box door 7. A motor 9 is provided in the box body 1, and the output end of the motor 9 is fixedly connected to the driving wheel 10. The driving wheel 10 is engaged with the driven wheel 8. A motor switch 11 is provided on the inner wall of the box body 1 on the side of the box door 7. Through the box door 7, one end of the advertising cloth 6 is fixed on the conveyor belt 5, and the conveyor belt 5 on the rotating roller 2 is driven to rotate by the motor 9, and the entire advertising cloth 6 is fixed at the box door 7. The disassembly of the advertising cloth 6 is similar, and the installation is efficient.

[0026] Glass windows 12 for displaying advertising cloths 6 are provided on the front and back sides of the box body 1. A scraper 13 is fixedly provided on the conveyor belt 5 between the advertising cloths 6. The scraper 13 moves together with the conveyor belt 5. The inner wall of the glass window 12 can be cleaned while replacing the advertising cloth 6 to ensure a good display effect of the advertisement. The conveyor belt 5 is made of a flexible and light-transmitting material, such as TPU.

[0027] The light source assembly includes a mounting plate 14, which is fixedly mounted on the bottom wall of the box 1 and is located inside the conveyor belt 5. Vertical long grooves 15 are opened on both sides of the mounting plate 14, and a lamp holder 16 is slidably installed in the vertical long groove 15. Lamp beads 17 are evenly arranged on the lamp holder 16 to illuminate the advertising cloth 6 on both sides respectively.

[0028] A connector 18 is provided on the top of the lamp holder 16, and the connector 18 is connected to the circuit on the mounting plate 14. A rotating seat 19 is movably installed at the bottom of the lamp holder 16, and the rotating seat 19 is threadedly connected to the bottom of the box 1. A notch 20 is provided at the bottom of the rotating seat 19. By rotating 19 to disengage it from the bottom of the box 1, the lamp holder 16 can be slid downward along the vertical slot 15 on the mounting plate 14 to be removed. The faulty lamp holder 16 can be repaired and replaced separately, which is convenient and quick. The notch 20 at the bottom of the rotating seat 19 requires professional tools to open to prevent it from being opened by non-staff, thereby improving safety.
