[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a graded legal education display device, including a first display frame 1, a second-level display plate 2 slidably installed inside the right end of the first display frame 1, a third-level display plate 3 slidably installed inside the left end of the first display frame 1, a pull-out positioning mechanism connecting the second-level display plate 2 and the third-level display plate 3 to the first display frame 1, the pull-out positioning mechanism including slid grooves 4 symmetrically opened at both ends of the rear side of the first display frame 1, a slide seat 5 slidably connected inside the slide grooves 4 at both ends, the right slide seat 5 being fixedly connected to the second-level display plate 2, the left slide seat 5 being fixedly connected to the third-level display plate 3, positioning bolts 6 being threadedly connected to the bottom of both ends of the first display frame 1, and positioning holes 7 being opened at the bottom of the outer ends of the second-level display plate 2 and the third-level display plate 3, the positioning holes 7 being movably engaged with the positioning bolts 6;

[0029] The design of the above structure allows the sliding block 5 to slide within the slide groove 4 by pushing and pulling the secondary display panel 2 and the tertiary display panel 3. This facilitates the limited sliding expansion and contraction of the secondary display panel 2 and the tertiary display panel 3. When the secondary display panel 2 and the tertiary display panel 3 are expanded, the positioning bolt 6 can be used to abut against the inner sides of the two panels to achieve the expanded positioning of the secondary display panel 2 and the tertiary display panel 3. When the secondary display panel 2 and the tertiary display panel 3 are contracted, the positioning bolt 6 can be used to engage with the positioning hole 7 to position the secondary display panel 2 and the tertiary display panel 3 after contraction.

[0030] A connecting seat 8 is symmetrically installed on the rear side of the first display frame 1. A positioning seat 9 is rotatably installed inside the connecting seat 8. A rotary positioning mechanism is connected between the positioning seat 9 and the connecting seat 8. The rotary positioning mechanism includes toothed grooves 10 opened at both ends of the positioning seat 9. Movable rods 11 are slidably installed inside both ends of the positioning seat 9. A control plate 12 is fixedly installed at the inner end of the movable rod 11. A first spring 13 is sleeved on the outer ring of the movable rod 11 between the control plate 12 and the inner side wall of the positioning seat 9. The movable rod 11 and the control plate 12 form a telescopic structure through the first spring 13. A gear 14 is fixedly installed at the outer end of the movable rod 11. The gear 14 is movably keyed to the toothed groove 10.

[0031] The design of the above structure allows the control plate 12 to slide inside the two ends of the positioning seat 9 by pushing the control plate 12 outward and the first spring 13 resetting the control plate 12. This causes the control plate 12 to drive the movable rod 11 to slide inside the two ends of the positioning seat 9, thereby driving the gears 14 at both ends to engage and disengage with the tooth grooves 10. When disengaged, the connecting seat 8 can be rotated at both ends of the positioning seat 9 by rotating it, thereby adjusting the display angle of the first display frame 1, the second-level display plate 2, and the third-level display plate 3. After the angle adjustment is completed, the positioning after the angle adjustment is achieved by using the engagement of the gears 14 and the tooth grooves 10.

[0032] A connecting block 15 is symmetrically installed on the rear side of the positioning seat 9. A fixing plate 16 is fixedly connected to the rear end of the connecting block 15. A slider 17 is fixedly installed on the rear sides of both ends of the fixing plate 16. A slide rail 18 is slidably connected to the rear end of the slider 17. A height positioning mechanism is connected between the slider 17 and the slide rail 18. The height positioning mechanism includes a limiting groove 19 opened inside the connecting block 15. A positioning rod 20 is symmetrically installed inside the limiting groove 19. A linkage plate 21 is slidably sleeved on the outer ring of the positioning rod 20. A second spring 22 is sleeved on the outer ring of the limiting groove 19 between the linkage plate 21 and the front side wall of the limiting groove 19. The linkage plate 21 forms a limiting telescopic structure with the limiting groove 19 through the second spring 22 and the positioning rod 20. A locking rod 23 is fixedly installed on the rear sides of both ends of the linkage plate 21. A locking groove 24 is opened inside the slide rail 18. The locking groove 24 is opened at equal intervals inside the slide rail 18. The locking groove 24 and the locking rod 23 are movably locked together.

[0033] The design of the above structure allows the linkage plate 21 to slide within the limiting groove 19 and the outer ring of the positioning rod 20 by pushing it forward. This causes the locking rod 23 to retract into the slider 17, releasing it from the locking groove 24. Then, by raising and lowering the connecting block 15, the sliders 17 at both ends of the fixed plate 16 can slide up and down within the slide rail 18, thereby adjusting the display height of the first display frame 1, the second-level display plate 2, and the third-level display plate 3. When the adjustment is complete, the push on the linkage plate 21 is released. At this time, the second spring 22 will push the linkage plate 21 and the locking rod 23 to reset, and the locking rod 23 will engage with the corresponding locking groove 24, realizing the positioning work after height adjustment.

[0034] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
