DETAILED DESCRIPTION

[0021] The technical scheme of the utility model will be further specifically explained below by taking examples and combining with the drawings.

[0022] Example: as Figures 1-5As shown, a back exposure mechanism turnover device based on narrow space application, including lamp bead fixed plate frame 1, lamp bead fixed plate frame 1 is equipped with lamp bead fixed plate assembly 2, lamp bead fixed plate assembly 2 both sides are equipped with side guide plate 3 which is slidingly inserted with lamp bead fixed plate assembly 2, side guide plate 3 is connected with lamp bead fixed plate frame 1. The lower front end of side guide plate 3 is equipped with guide piece 5 which is fixedly connected with lamp bead fixed plate frame 1, and four bearings 4 are arranged between guide piece 5 and lamp bead fixed plate frame 1.

[0023] Lamp bead fixed plate assembly 2 includes lamp bead mounting plate 9, and 72 back exposure lamp beads 12 are arranged in an array on the lamp bead mounting plate 9. Rotating pin fixed blocks 8 are arranged on both sides of the lamp bead mounting plate 9, and wrenches 10 are arranged at the front ends of the rotating pin fixed blocks 8. The wrenches 10 are in the form of "L" shaped block structure. Pin shafts 6 and return springs 7 are arranged at the front and rear ends of the rotating pin fixed blocks 8. A sliding groove 11 is arranged on the side guide plate 3 and movably inserted with the rear pin shaft 6. A fixed groove 13 is arranged at the front end of the side guide plate 3 and movably inserted with the front pin shaft 6.

[0024] When the lamp beads fail, the wrenches 10 at the front end of the rotating pin fixed blocks 8 are pulled inward, and the internal pin shafts 6 are retracted, so that the pin shafts 6 are pulled out of the fixed grooves 13 of the side guide plates 3. At this time, one side of the lamp bead fixed plate assembly 2 is lowered. The ingenious design of the wrenches 3 and the internal pin shafts 6 makes the installation and loosening of the whole mechanism more convenient and reliable. When the rotating pin fixed blocks 8 contact the lower bearings 4, the whole lamp bead fixed plate assembly 2 slides along the bearings 4 until the rear pin shaft 6 of the rotating pin fixed block 12 reaches the end of the sliding groove 11 in the side guide plate 3. At this time, the lamp bead fixed plate assembly 2 reaches the maintenance position. The angle design of the sliding groove 11 enables the whole assembly to reach the working position and the maintenance position. When the working position is reached, the lamp bead fixed plate frame 1 is effectively dustproof and exposed to light. When the maintenance position is reached, there is enough space and a convenient maintenance angle for maintenance and debugging. The design of the bearings 4 and the guide pieces 5 makes the whole operation process easy and smooth.

[0025] In summary, the back exposure mechanism turnover device based on narrow space application has the characteristics of simple structure, convenient operation and good running stability. It solves the problem of difficult operation during maintenance. It can turn over the back exposure lamp bead plate downward inside the device for maintenance.
