[0015] Beneficial Effects

[0016] 1. The two light box bodies are clamped and limited by their own gravity through the cooperation of the moving mechanism and the card-in mechanism, and then they are synchronously lifted and moved toward each other to be carded into the sliding groove for card-connection installation. This can improve the rapid installation of the two light box bodies and facilitate the later disassembly. There is no need for manual climbing and hand-held limit installation, which greatly improves work efficiency and safety.

[0017] 2. By placing the light box body on the pressure plate, the gravity of the light box body drives the sliding column, connecting plate and movable rod to press downward, so that the clamping plates move toward each other in the horizontal through groove, thereby realizing the self-gravity clamping and fixing of both sides of the light box body. The extrusion spring and the rubber clamp block can play a certain buffering role when the light box body is clamped by self-gravity, and can also ensure that the light box body is fully fitted and clamped, thereby improving the clamping efficiency and stability. It can also automatically release the clamping after installation, greatly improving work efficiency.

[0018] 3. By rotating the motor, the threaded rod, the threaded block and the two-way telescopic rod, the light box body on the card-in mechanism is driven to move smoothly upward to the installation position, and then the two light box bodies are driven to move toward each other, so that the card-connecting block on the light box body is inserted into the entry and exit slot. Then, the motor is rotated to drive the light box body on the card-in mechanism to move downward, so that the card-connecting block moves to the lowest end of the sliding slot to complete the card-connection and fixation. The light box body continues to move downward, and the light box body no longer squeezes the pressure plate. The splint automatically releases the clamping fixation of the light box body, completing the rapid installation of the two light box bodies. There is no need for manual climbing and hand-held horizontal limit, which greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Through the cooperation of the structure of the clamping block 23 and the clamping groove 11, stable fixation can be achieved only by clamping.

[0031] Please refer to Figure 3, in this embodiment, the moving mechanism 3 includes a moving base 31. The moving base 31 is installed on the driving vehicle 32. Above the moving base 31, a U-shaped frame 33 is installed. A threaded rod 34 is vertically arranged inside the U-shaped frame 33. The lower end of the threaded rod 34 is rotatably connected inside the U-shaped frame 33, and the upper end of the threaded rod 34 is connected to the output end of the rotating motor 35. The rotating motor 35 is installed at the top of the U-shaped frame 33 through a motor base. An elevating slide block 36 is installed on the threaded rod 34 by threaded fit. The elevating slide block 36 includes a threaded block 361. On the end face of the threaded block 361 close to the lamp post 1, connecting plates 362 are symmetrically installed up and down. A positioning block 363 is installed between the connecting plates 362.

Supporting plates 364 are installed at the positions corresponding to the upper end of the positioning block 363 and the clamping groove 11 up and down. During operation, the position is moved through the existing driving vehicle 32, so that the positioning block 363 can be attached to the outer wall of the lamp post 1. The rotating motor 35 is started to drive the threaded block 361 to move up and down through the threaded rod 34, so that the positioning block 363 can move along the outer wall of the lamp post 1. The smoothness of the movement is improved by a plurality of balls, and the friction force is reduced.

[0032] Please refer to Figure 2 , Figure 3 , Figure 4 , in this embodiment, the clamping mechanism 4 includes a bidirectional telescopic rod 41. The bidirectional telescopic rod 41 is fixedly installed through the positioning block 363 located between the two connecting plates 362. L-shaped frames 42 are installed at the telescopic ends of the bidirectional telescopic rod 41. Clamping units 43 are installed on the upper right sides of the L-shaped frames 42. The clamping unit 43 includes a placement box 44. The placement box 44 is installed on the L-shaped frame 42. A return-shaped baffle 45 is installed on the upper end face of the placement box 44. A storage groove is opened in the middle of the upper end face of the placement box 44. A gravity assembly 46 is arranged in the cavity of the placement box 44. A clamping assembly 47 connected to the gravity assembly 46 is arranged on the placement box 44. The gravity assembly 46 and the clamping assembly 47 are connected through a movable rod 48. Through the bidirectional telescopic rod 41, when the clamping assembly 47 clamps and fixes the two light box bodies 2 and moves them to the installation position, the two light box bodies 2 can be driven to move towards each other, so that the clamping blocks 23 on the light box bodies 2 are inserted into the clamping grooves 11.

[0033] Refer to Figure 5 , Figure 6 , Figure 7The gravity assembly 46 includes a pressure plate 461, which is made of rubber. The upper end surface of the pressure plate 461 is evenly provided with a V-shaped groove for anti-slip. The pressure plate 461 is arranged in the storage slot. The bottom of the storage slot is evenly provided with a through hole connected to the internal cavity of the placement box 44. Slide columns 462 are slidably arranged in the through holes. The lower ends of the slide columns 462 are installed with waist-shaped plates 463. The lower ends of the waist-shaped plates 463 are provided with restoring springs 464. The lower ends of the restoring springs 464 are connected to the inner wall of the bottom of the placement box 44. The clamping assembly 47 includes a clamping plate 471. The upper end surface of the placement box 44 is located on the left and right sides of the storage slot and is evenly provided with a plurality of horizontal through grooves 472 connected to the internal cavity of the placement box 44. , clamping plates 471 are slidably installed in the horizontal through grooves 472, and the front and rear adjacent clamping plates 471 are connected by reinforcing plates 473. Rectangular grooves are evenly opened on the opposite surfaces of the clamping plates 471 above the horizontal through grooves 472, and extrusion springs 474 are installed in the rectangular grooves. Connecting plates 475 are slidably installed on the inner walls of the rectangular grooves. The side of the connecting plate 475 close to the extrusion spring 474 is connected to the extrusion spring 474, and a rubber clamping block 476 is installed on the side away from the extrusion spring 474. One end of the movable rod 48 is connected to the lower end of the clamping plate 471 through a pin shaft, and docking grooves are opened on the left and right sides of the waist-shaped plate 463 at the positions corresponding to the movable rod 48, and the other end of the movable rod 48 is installed in the docking groove through a pin shaft. During operation, by placing the lamp box body 2 on the placement box 44 between the clamping components 47, the bottom of the lamp box body 2 contacts the pressure plate 461. After the pressure plate 461 is subjected to pressure, it drives the sliding column 462 to slide in the through hole. The sliding column 462 moves downward and pulls the movable rod 48 downward through the connecting plate 475. Since the upper end of the movable rod 48 is connected to the clamping plate 471 which is limited in the horizontal through groove 472, when the lower end of the movable rod 48 moves downward, the upper end of the movable rod 48 rotates toward the position of the sliding column 462, thereby driving the clamping plate 471 to move toward each other in the horizontal through groove 472, thereby clamping and fixing the two sides of the lamp box body 2. The extrusion spring 474 cooperates with the rubber clamp block 476 to play a certain buffering role when clamping the lamp box body 2 by its own gravity, and can also ensure that the lamp box body 2 is fully fitted and clamped.

[0034] During specific operation, the existing driving vehicle 32 is used to move the position so that the positioning block 363 can fit with the outer wall of the lamp post 1, and the lamp box body 2 is placed on the placement box 44 between the clamping components 47. The bottom of the lamp box body 2 contacts the pressure plate 461. After the pressure plate 461 is pressed, it drives the sliding column 462 to slide in the through hole. The sliding column 462 moves downward and pulls the movable rod 48 downward through the waist-shaped plate 463. Since the upper end of the movable rod 48 is connected to the clamping plate 471 which is slidably limited in the horizontal through groove 472, when the lower end of the movable rod 48 moves downward, the upper end of the movable rod 48 rotates toward the position of the sliding column 462, thereby driving the clamping plate 471 to move toward each other in the horizontal through groove 472, so as to clamp and fix the two sides of the lamp box body 2. The extrusion spring 474 cooperates with the rubber clamping block 476 to play a certain buffering role when clamping the lamp box body 2 by its own gravity, and can also be used according to the protection To ensure that the lamp box body 2 is fully fitted and clamped, the rotating motor 35 is started to drive the threaded block 361 to move upward through the threaded rod 34, so that the positioning block 363 can fit the outer wall of the lamp post 1 and move upward, and the two-way telescopic rod 41 drives the two lamp box bodies 2 to move toward each other, so that the clamping block 23 on the lamp box body 2 is inserted into the entry and exit groove 111, and then the rotating motor 35 is reversed, so that the clamping mechanism 4 drives the two lamp box bodies 2 to move downward, and at the same time, the clamping block 23 of the lamp box body 2 slides downward in the sliding groove 112. When it moves to the lowest end of the sliding groove 112, the rotating motor 35 continues to drive the lamp box body 2 to move downward. At this time, with the supporting force of the clamping block 23 and the sliding groove 112, the lamp box body 2 no longer squeezes the pressure plate 461, and the recovery spring 464 drives the sliding column 462 and the pressure plate 461 to return to their original positions, thereby completing the rapid installation of the two lamp box bodies 2.

[0035] When the light box body 2 on the lamp post 1 needs to be replaced, the card-in mechanism 4 is driven by the two-way telescopic rod 41 to move to the bottom of the light box body 2, and then the rotating motor 35 drives the positioning block 363 and the card-in mechanism 4 to move upward. The positioning block 363 is provided with a supporting plate 364, and the supporting plate 364 supports the card-connecting root of the light box body 2 to prevent the card-connecting block 23 from being unable to maintain level with the billboard 21 only by moving upward through the card-in mechanism 4, thereby preventing the card-connecting block 23 from being able to maintain level with the billboard 21, thereby causing a jam. The supporting plate 364 cooperates with the card-in mechanism 4 to lift the lower end of the light box body 2 upward, so that the light box body 2 moves upward in the sliding groove 112. Similarly, the card-in mechanism 4 automatically clamps and fixes after being subjected to the gravity of the light box body 2. When it moves to the position of the entry and exit groove 111, the two-way telescopic rod 41 drives the two light box bodies 2 on the card-in mechanism 4 to move back to back, and the light box body 2 is removed from the lamp post 1.
