[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example 1, by Figure 1 , Figure 4 , Figure 8 and Figure 9 The present invention includes several bases 1 arranged in sequence. A display panel 2 and a transparent panel 4 are provided on the top of the bases 1. The display panel 2 has a receiving groove 3 for placing an electronic screen on the side facing the transparent panel 4. The display panel 2 is equipped with a gravity plug fitting adapted to the transparent panel 4. The bases 1 are equipped with a damping rotation mechanism adapted to the display panel 2. Several rollers 5 are fixedly connected to the bottom of the bases 1. Adjacent bases 1 are connected by a locking mechanism.

[0037] The base 1 has first sliding grooves 6 on both sides, and first sliding plates 7 slide within the first sliding grooves 6. Support plates 8 and support sleeves 9 are fixedly connected to the opposite sides of two adjacent first sliding plates 7. A first rotating shaft 10, compatible with the support sleeve 9, is fixedly connected to the top of the support plate 8. The top horizontal position of the support plate 8 is the same as the bottom horizontal position of the support sleeve 9. The base 1 is equipped with a pressing structure compatible with the first sliding plates 7. The operator places the electronic screen to be displayed into the receiving slot 3, fixes the transparent plate 4 onto the display plate 2 using gravity connectors, adjusts the tilt angle of the display plate 2 using a damping rotation mechanism, and releases the fixed relationship between several bases 1 using a locking mechanism. The operator then uses rollers 5... Several bases 1 are driven to move, and the first sliding plate 7 slides relative to the first sliding groove 6, so that the support plate 8 and the support sleeve 9 slide out of the first sliding groove 6 respectively. The support sleeve 9 rotates relative to the support plate 8 and the first rotating shaft 10, adjusting the placement of the bases 1 so that several bases 1 are arranged in an arc. Then, the position of the first sliding plate 7 is limited by the pressing structure, so that the first sliding plate 7 is fixed relative to the base 1. With the arc-shaped bases 1 and the display plate 2, multiple electronic screens can be viewed through the transparent plate 4 without the viewer having to move. The installation method of the electronic screens can be changed, making it easier to replace the electronic screens. The display plate 2 and the transparent plate 4 protect the electronic screens and avoid the influence of the external environment on the electronic screens, so as to improve the display effect.

[0038] Example 2, based on Example 1, is... Figure 5 , Figure 6 , Figure 8 and Figure 9 The pressing structure includes two first movable plates 11 disposed above the base 1. A pressing block 47 is fixedly connected to the bottom of each first movable plate 11. A clearance hole 12, adapted to the pressing block 47, is provided on the top inner wall of the first sliding groove 6, and the pressing block 47 is located above the clearance hole 12. At least two first guide posts 13 are fixedly connected to the bottom of each first movable plate 11. The first guide posts 13 penetrate the base 1, and an anti-slip plate 14 is fixedly connected to the bottom end of each first guide post 13. The top of the anti-slip plate 14 and the bottom of the base 1 are connected by a compression spring 15. The base 1 is equipped with a support unit adapted to the first movable plates 11. The support unit includes two second movable plates 16 disposed above the base 1. Two support bars 17 located below the first movable plate 11 are fixedly installed on the second movable plates 16. A first fixed sleeve 18 is slidably sleeved on the outside of the support bars 17, and the first fixed sleeve 18 is fixedly connected to the base 1. The top of the support bar 17 is in contact with the bottom of the first movable plate 11. An anti-detachment block 19 is fixedly connected to the end of the support bar 17 away from the second movable plate 16. Guide grooves 20 are respectively opened on the inner walls of the two sides of the first slide groove 6. Guide blocks 21 are fixedly connected to the two sides of the first slide plate 7, and the guide blocks 21 are located in the corresponding guide grooves 20.

[0039] The operator pulls two adjacent bases 1 to move them, causing the first sliding plate 7 to slide relative to the first sliding groove 6 and base 1. The support bar 17 supports the first movable plate 11, ensuring that the pressing block 47 does not contact the first sliding plate 7. At this time, the compression spring 15 is compressed, applying pressure to the anti-slip plate 14, the first guide post 13, and the first movable plate 11, causing the first movable plate 11 and the support bar 17 to abut against each other. After the position of the base 1 is adjusted, the operator pushes the second movable plate 16 and the support bar 17 to slide relative to the first fixed sleeve 18 and base 1, so that the support bar 17 no longer supports the first movable plate 11, and the anti-detachment block 19 is in contact with the first fixed sleeve 18. The fixed sleeve 18 abuts against each other. The design of the anti-detachment block 19 prevents the support bar 17 from detaching from the first fixed sleeve 18. At this time, the compression spring 15 pushes the anti-slip plate 14, the first guide post 13 and the first movable plate 11 to move down, so that the pressing block 47 moves relative to the clearance hole 12, and the bottom of the pressing block 47 abuts against the top of the first slide plate 7. The anti-slip plate 14 contacts the ground, so that the first slide plate 7 is fixed relative to the base 1, and the anti-slip plate 14 supports the base 1, reducing the possibility of the base 1 sliding relative to the ground. When the first slide plate 7 moves, the guide block 21 slides in the guide groove 20. The design of the guide block 21 and the guide groove 20 prevents the first slide plate 7 from detaching from the first slide groove 6.

[0040] Example 3, based on Example 1, is... Figure 5 , Figure 7 and Figure 8 The locking mechanism includes several support blocks 22 fixedly mounted on the top of the base 1. First insert blocks 23 are fixedly mounted on the support blocks 22. Several second fixing sleeves 24, adapted to the first insert blocks 23, are fixedly mounted on the top of the base 1. The second fixing sleeves 24 are located on the side of the support blocks 22 away from the first insert blocks 23. The number of first insert blocks 23 and second fixing sleeves 24 is the same. A positioning groove 25 is provided on the top of the first insert block 23. A third movable plate 26 is provided above the second fixing sleeves 24. The bottom of the third movable plate 26 is fixedly connected to a fixing sleeve. The positioning post 27 is adapted to the slot 25. The base 1 is equipped with a reset unit adapted to the third movable plate 26. The reset unit includes at least two first magnet blocks 31 arranged above the third movable plate 26. The bottom of the first magnet block 31 is fixedly connected to a second guide post 28. The second guide post 28 passes through the third movable plate 26, and the bottom end of the second guide post 28 is fixedly connected to the base 1. An iron ring 30 located above the third movable plate 26 is fixedly sleeved on the outside of the second guide post 28. The third movable plate 26 and the base 1 are connected by a tension spring 29.

[0041] When the electronic screen is not needed, the staff drives two adjacent bases 1 to contact each other, and the first slide plate 7 slides into the first slide groove 6. At this time, the top of the iron ring 30 and the bottom of the first magnet block 31 are magnetically attracted, and the tension spring 29 is in a stretched state. The first insert 23 above one of the bases 1 passes through the second fixing sleeve 24 above the other base 1, and the positioning groove 25 on the first insert 23 moves to the bottom of the corresponding second guide post 28. The staff drives the third movable plate 26 and the iron ring 30 to move down, and the iron ring 30 is no longer magnetically attracted to the first magnet block 31. The tension spring 29 pulls the third movable plate 26, the positioning post 27 and the iron ring 30 to move down, so that the bottom end of the positioning post 27 is inserted into the corresponding positioning groove 25, so that the two adjacent bases 1 can be connected together. The staff can push several bases 1 to move synchronously through the roller 5.

[0042] Example 4, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 and Figure 4 The gravity connector includes several mounting plates 32 fixedly mounted on a transparent plate 4. Second insert blocks 33 are fixedly mounted on the mounting plates 32. A third fixing sleeve 34 is slidably fitted onto the outer side of the second insert blocks 33, and the third fixing sleeve 34 is fixedly connected to the display plate 2. A support portion 35 is fixedly connected to the side of the third fixing sleeve 34 away from the mounting plates 32. A second sliding plate 36 passes through the support portion 35. A second sliding groove 37 adapted to the second sliding plate 36 is formed on the second insert blocks 33. An iron plate 38 is fixedly connected to the top of the second sliding plate 36, and the iron plate 38 contacts the support portion 35. A second magnet block 40 is provided above the iron plate 38, and the third fixing sleeve 34... 4. The second magnet block 40 is fixedly connected by the fixing frame 39. The damping rotation mechanism includes a second rotating shaft 41 fixedly installed on both sides of the display plate 2. A support seat 42 is rotatably sleeved on the outside of the second rotating shaft 41. The support seat 42 and the base 1 are fixedly connected. A friction disc 43 is fixedly connected on the side of the second rotating shaft 41 away from the display plate 2. A friction seat 44 is contacted on the side of the friction disc 43 away from the second rotating shaft 41. At least two lead screws 45 are fixedly connected on the side of the friction seat 44 facing the display plate 2. The lead screws 45 pass through the support seat 42. Two nuts 46 are sleeved on the outside of the lead screws 45, and two adjacent nuts 46 are located on both sides of the support seat 42.

[0043] Friction seat 44 contacts friction disc 43. The operator drives display panel 2 and second rotating shaft 41 to rotate. Second rotating shaft 41 drives friction disc 43 to rotate relative to friction seat 44. When display panel 2 is rotated to a horizontal position, the opening of receiving groove 3 faces upward. Through the friction between friction disc 43 and friction seat 44, display panel 2 is kept stationary relative to support seat 42 and base 1. At this time, iron plate 38 and second magnet block 40 are magnetically attracted. Second sliding plate 36 does not obstruct second insert block 33 from passing through third fixing sleeve 34. The operator places electronic screen in receiving groove 3. Then the operator drives transparent plate 4 to move so that transparent plate 4 drives second insert block 33 to pass through third fixing sleeve 34 via mounting plate 32. Second sliding groove 37 on second insert block 33 moves to one side of second sliding plate 36. Display panel 2 and transparent plate 4 come into contact. The operator drives display panel 2 and transparent plate 4 to rotate in opposite directions. At the preset tilt angle, as the display panel 2 and transparent panel 4 rotate, the second insert 33 moves to below the second slide plate 36 and iron plate 38. The gravity on the second slide plate 36 and iron plate 38 is greater than the magnetic force between the iron plate 38 and the second magnet 40, so that the magnetic attraction between the iron plate 38 and the second magnet 40 is released. The bottom end of the second slide plate 36 slides into the second slide groove 37, and the iron plate 38 and the support part 35 abut against each other, thus preventing the second insert 33 from shaking relative to the third fixing sleeve 34. After the transparent panel 4 and the display panel 2 rotate to the preset angle, the transparent panel 4 is fixedly connected to the display panel 2. The operator drives the nut 46 to rotate, so that the nut 46 disengages from the screw 45, releasing the fixed relationship between the screw 45 and the support seat 42. The operator drives the friction seat 44 and the screw 45 to move, so that the screw 45 disengages from the support seat 42, thus completing the removal of the friction seat 44 and the screw 45.

[0044] This embodiment of a prefabricated movable display method, using the prefabricated movable display device as described above, includes the following steps:

[0045] Step 1: The staff places the electronic screen to be displayed into the receiving slot 3, and fixes the transparent plate 4 onto the display plate 2 using gravity connectors;

[0046] Step 2: Adjust the tilt angle of the display panel 2 through the damping rotation mechanism, and release the fixed relationship between several bases 1 through the locking mechanism;

[0047] Step 3: The staff drives several bases 1 to move using rollers 5, and the first slide plate 7 slides relative to the first slide groove 6 so that the support plate 8 and the support sleeve 9 slide out of the first slide groove 6 respectively;

[0048] Step 4: The staff drives the base 1 to move so that the support sleeve 9 rotates relative to the support plate 8 and the first rotating shaft 10, adjusts the placement of the base 1, and arranges several bases 1 in an arc shape. Then, the position of the first slide plate 7 is limited by the pressing structure so that the first slide plate 7 is fixed relative to the base 1.

[0049] Working principle: The staff places the electronic screen to be displayed in the receiving slot 3, and fixes the transparent plate 4 to the display plate 2 through the gravity plug. The tilt angle of the display plate 2 is adjusted by the damping rotation mechanism. The fixing relationship between several bases 1 is released by the locking mechanism. The staff drives several bases 1 to move through the rollers 5. The first slide plate 7 slides relative to the first slide groove 6, so that the support plate 8 and the support sleeve 9 slide out from the first slide groove 6 respectively. The support sleeve 9 rotates relative to the support plate 8 and the first rotating shaft 10 to adjust the placement position of the bases 1 so that several bases 1 are arranged in an arc. Then, the position of the first slide plate 7 is limited by the pressing structure to fix the first slide plate 7 relative to the base 1. With the arc-shaped placement of the bases 1 and the display plate 2, multiple electronic screens can be viewed through the transparent plate 4 without the viewer having to move. Changing the installation method of the electronic screen makes it easier to replace the electronic screen. The display plate 2 and the transparent plate 4 protect the electronic screen and avoid the influence of the external environment on the electronic screen, so as to improve the display effect.

[0050] The operator pulls two adjacent bases 1 to move them, causing the first sliding plate 7 to slide relative to the first sliding groove 6 and base 1. The support bar 17 supports the first movable plate 11, ensuring that the pressing block 47 does not contact the first sliding plate 7. At this time, the compression spring 15 is compressed, applying pressure to the anti-slip plate 14, the first guide post 13, and the first movable plate 11, causing the first movable plate 11 and the support bar 17 to abut against each other. After the position of the base 1 is adjusted, the operator pushes the second movable plate 16 and the support bar 17 to slide relative to the first fixed sleeve 18 and base 1, so that the support bar 17 no longer supports the first movable plate 11, and the anti-detachment block 19 is in contact with the first fixed sleeve 18. The fixed sleeve 18 abuts against each other. Through the design of the anti-detachment block 19, the support bar 17 is prevented from detaching from the first fixed sleeve 18. At this time, the compression spring 15 pushes the anti-slip plate 14, the first guide post 13 and the first movable plate 11 to move down, so that the pressing block 47 moves relative to the clearance hole 12, and the bottom of the pressing block 47 abuts against the top of the first slide plate 7. The anti-slip plate 14 contacts the ground, so that the first slide plate 7 is fixed relative to the base 1, and the anti-slip plate 14 supports the base 1, reducing the possibility of the base 1 sliding relative to the ground. When the first slide plate 7 moves, the guide block 21 slides in the guide groove 20. Through the design of the guide block 21 and the guide groove 20, the first slide plate 7 is prevented from detaching from the first slide groove 6.

[0051] When the electronic screen is not needed, the staff drives two adjacent bases 1 to contact each other, and the first slide plate 7 slides into the first slide groove 6. At this time, the top of the iron ring 30 and the bottom of the first magnet block 31 are magnetically attracted, and the tension spring 29 is in a stretched state. The first insert block 23 above one of the bases 1 passes through the second fixing sleeve 24 above the other base 1, and the positioning groove 25 on the first insert block 23 moves to the bottom of the corresponding second guide post 28. The staff drives the third movable plate 26 and the iron ring 30 to move down, and the iron ring 30 is no longer magnetically attracted to the first magnet block 31. The tension spring 29 pulls the third movable plate 26, the positioning post 27 and the iron ring 30 to move down, so that the bottom end of the positioning post 27 is inserted into the corresponding positioning groove 25, so that the two adjacent bases 1 can be connected together. The staff can push several bases 1 to move synchronously through the roller 5.

[0052] Friction seat 44 contacts friction disc 43. The operator drives display panel 2 and second rotating shaft 41 to rotate. Second rotating shaft 41 drives friction disc 43 to rotate relative to friction seat 44. When display panel 2 is rotated to a horizontal position, the opening of receiving groove 3 faces upward. Through the friction between friction disc 43 and friction seat 44, display panel 2 is kept stationary relative to support seat 42 and base 1. At this time, iron plate 38 and second magnet block 40 are magnetically attracted. Second sliding plate 36 does not obstruct second insert block 33 from passing through third fixing sleeve 34. The operator places electronic screen in receiving groove 3. Then the operator drives transparent plate 4 to move so that transparent plate 4 drives second insert block 33 to pass through third fixing sleeve 34 via mounting plate 32. Second sliding groove 37 on second insert block 33 moves to one side of second sliding plate 36. Display panel 2 and transparent plate 4 come into contact. The operator drives display panel 2 and transparent plate 4 to rotate in opposite directions. At the preset tilt angle, as the display panel 2 and transparent panel 4 rotate, the second insert 33 moves to below the second slide plate 36 and iron plate 38. The gravity on the second slide plate 36 and iron plate 38 is greater than the magnetic force between the iron plate 38 and the second magnet 40, so that the magnetic attraction between the iron plate 38 and the second magnet 40 is released. The bottom end of the second slide plate 36 slides into the second slide groove 37, and the iron plate 38 and the support part 35 abut against each other, thus preventing the second insert 33 from shaking relative to the third fixing sleeve 34. After the transparent panel 4 and the display panel 2 rotate to the preset angle, the transparent panel 4 is fixedly connected to the display panel 2. The operator drives the nut 46 to rotate, so that the nut 46 disengages from the screw 45, releasing the fixed relationship between the screw 45 and the support seat 42. The operator drives the friction seat 44 and the screw 45 to move, so that the screw 45 disengages from the support seat 42, thus completing the removal of the friction seat 44 and the screw 45.
