A light homogenizing plate is installed on the outer frame, and the light homogenizing plate covers the outside of the back plate. The image light emitting component 6 can be replaced as a whole.

[0026] When the specification of the image light-emitting component 6 changes, it is necessary to adjust the horizontal spacing between the two vertical frame plates 4, that is, the horizontal spacing between the two vertical frame plates 4 can be changed, which requires that each vertical frame plate 4 is slidably connected to the flat hanging plate 3. Specifically, a strip slide 7 is provided on the flat hanging plate 3, and a positioning seat is fixed at the upper end of the vertical frame plate 4. The positioning seat consists of three parts, namely an upper baffle plate, a lower baffle plate and an intermediate hanging plate. The intermediate hanging plate is located in the strip slide 7, so that the positioning seat can slide in the strip slide 7 and along the length direction of the strip slide 7. The upper baffle plate and the lower baffle plate can prevent the vertical frame plate 4 from separating from the flat hanging plate 3. A locking bolt is screwed on the lower baffle plate. When the position adjustment of the positioning seat is completed, the positioning seat and the vertical frame plate can be positioned by tightening the locking bolt, and then the image light-emitting component is placed between the two vertical frame plates 4 and moved upward through the bottom support plate 5. Finally, the bottom support plate 5 and the flat hanging plate 3 clamp and position the image light-emitting component.

[0027] The bottom support plate 5 is controlled to move upward through the following structure: a suspension rope 8 is connected to the bottom support plate 5, and the suspension rope 8 passes through the vertical frame plate 4. Specifically, a vertical through hole 9 is provided on the positioning seat, and a vertical channel 10 is provided in the vertical frame plate 4. The vertical channel 10 is connected to the vertical through hole 9, and the suspension rope 8 passes through the vertical channel 10 and the vertical through hole 9. Since the horizontal spacing between the two vertical frame plates 4 can be adjusted, a strip opening is also provided on the bottom support plate 5, and this strip opening is parallel to the strip sliding opening on the flat hanging plate 3. A slidable bottom suspension seat 11 is provided in this strip opening. The composition structure of the bottom suspension seat 11 is the same as that of the positioning seat, and the lower end of the suspension rope 8 is fixed to the bottom suspension seat 11. On, the upper end of the suspension rope 8 is connected to the arch hanger 2, and a base 12 and an outer pull seat are arranged on the flat suspension plate 3, the base 12 is fixedly connected to the flat suspension plate 3, the outer pull seat includes a sliding part 13 and a ring body 14, the ring body 14 is fixed on the sliding part 13, the sliding part 13 is slidably connected to the flat suspension plate 3, the ring body 14 is sleeved on the suspension rope 8, and a horizontally penetrating threaded hole passes through the base 12, a screw rod 15 passes through the base, one end of the screw rod 15 is movably connected to the outer pull seat, and the other end of the screw rod 15 is fixed with a handle 16, when the screw rod 15 rotates and drives the outer pull seat to slide in a direction away from the image light-emitting component, the outer pull seat can apply a horizontal pulling force to the suspension rope 8 to move the bottom support plate 5 upward.

[0028] In addition, a stabilizing arm 17 is hinged on the vertical frame plate 4, the lower end of the stabilizing arm 17 is hinged to the vertical frame plate 4, and a cushion block 18 is fixed to the upper end of the stabilizing arm 17. A locking hole is provided on the stabilizing arm 17, and a matching hole is provided on the vertical frame plate 4. When the stabilizing arm 17 is flipped to a vertical state, the locking hole is aligned with the matching hole. After the image light-emitting component is clamped and positioned, the stabilizing arm 17 is flipped to a vertical state. At this time, the bolts can be screwed in to connect the stabilizing arm 17 to the vertical frame plate 4. When the stabilizing arm 17 is connected to the vertical frame plate 4, the cushion block 18 rests on the inner wall of the tunnel, thereby increasing the position stability of the light box body 1.

[0029] The above-mentioned arch hanger 2 is also provided with a cross bracing beam 19, which is horizontally arranged. Both ends of the cross bracing beam 19 are fixedly connected to the arch hanger 2, so that the arch hanger 2 has a certain supporting strength. The cross bracing beam 19 is also provided with a fastening device, which can be connected to the suspension rope 8. The fastening device includes a slide 20 arranged on the cross bracing beam 19, and the slide 20 is sleeved on the cross bracing beam 19. The slide 20 can slide on the cross bracing beam 19.

The arch hanger 2 is provided with a socket for passing the fastening rod 21. When the outer pull seat applies a horizontal pulling force to the suspension rope 8, the suspension rope 8 will gradually tighten, and the slide 20 moves toward the inner wall of the tunnel. , the fastening rod 21 applies pressure to the tunnel wall. To ensure the state of the fastening rod, a limiting sleeve 22 is fixed on the cross bracing beam 19. The limiting sleeve 22 extends along the length direction of the cross bracing beam 19. The fastening rod 21 passes through the cross bracing beam 19, but the outer end and the inner end of the fastening rod 21 are both located outside the limiting sleeve 22, that is, the length of the limiting sleeve 22 is less than the length of the fastening rod 21. The outer end of the fastening rod 21 is connected to the slide 20. To increase the deformability of the suspension rope 8, a flat through hole for passing the fastening rod 21 is provided on the slide 20. A spring is connected between the outer end of the fastening rod 21 and the slide 20. After the suspension rope 8 is subjected to horizontal tension, the slide 20 will slide on the cross bracing beam 19 toward the inner wall of the tunnel, and the spring begins to deform at this time;

[0030] There are two structures for connecting the slide 20 and the fastening rod 21:

[0031] See also Figure 6 As shown, in the first structure, the spring is a tension reset spring 23, the tension reset spring 23 is sleeved on the fastening rod 21, the inner end of the tension reset spring 23 is fixed to the slide 20, and the outer end of the tension reset spring 23 is fixed with a push plate 24, and the push plate 24 is fixed to the outer end of the fastening rod 21. When the slide 20 moves toward the inner wall of the tunnel, the tension reset spring 23 is stretched;

[0032] See also Figure 7 As shown, in the second structure, the spring is a compression return spring 25. In this case, the compression return spring 25 is also sleeved on the fastening rod 21, and the push plate 24 is arranged on the fastening rod 21 near the outer end. The push plate 24 is located between the limit sleeve 22 and the slide 20. When the slide 20 moves toward the inner wall of the tunnel, the compression return spring 25 is compressed.

[0033] Regardless of which structure is selected, the restoring force of the spring can be used to apply a thrust to the fastening rod 21, so that the inner end of the fastening rod 21 is tightly pressed against the inner wall of the tunnel, thereby increasing the tightness of the connection between the arch hanger 2 and the inner wall of the tunnel.

[0034] It should be noted that when the above solution is used to clamp and position the image light emitting component, the prerequisite is that the flat hanging plate 3 needs to be docked with the end of the arched hanger 2. The specific docking structure is as follows:

[0035] An elongated mating seat 26 is fixed at the end of the arch hanger 2, and an upwardly extending slot 27 is arranged on the lower surface of the mating seat 26. At the same time, an insert plate 28 is fixed on the upper surface of the flat hanger plate 3. When the flat hanger plate 3 is docked with the arch hanger 2, the insert plate 28 can be inserted into the slot 27. A plug hole is arranged on the insert plate 28, and a threaded through hole is arranged on the mating seat 26. The threaded through hole is connected to the slot. After the insert plate 28 is inserted into the slot 27, it can be screwed into the threaded through hole by a bolt, thereby forming a connection between the two.

[0036] When the lifting rope 8 is connected to the sliding seat 20, the lifting rope 8 is passed through the arch hanger 2. First, a buried groove 29 is set on the upper surface of the matching seat 26. The buried groove 29 extends along the length direction of the matching seat 26, and a transition channel 30 is set in the arch hanger 2. The transition channel 30 extends from the end of the arch hanger 2 to the middle. A circular hole is set on the inner surface of the arch hanger 2. The lifting rope 8 turns above the outer pull seat and enters the buried groove 29. Then the lifting rope 8 enters the transition channel 30. Finally, the upper end of the lifting rope 8 passes through the circular hole and is connected to the sliding seat 20.

[0037] Guide wheels are provided at the turning positions of the above-mentioned lifting ropes 8 to reduce the wear of the lifting ropes.
