The upper support column is fixed to the back of the display screen, and the lower support column is rotatably connected to the bottom end of the upper support column. A torsion spring is installed at the connection between the upper and lower support columns, and the upper and lower support columns are elastically connected by the torsion spring. External threads are provided on the outer walls of both the upper and lower support columns. A threaded sleeve is engaged with the outer wall of the upper support column. The base plate mechanism is rotatably installed at the bottom end of the lower support column, and a torsion spring is installed at the rotating part of the bottom end of the lower support column. The lower support column is elastically connected to the base plate mechanism by the torsion spring. This foldable display screen can be aligned and fixed by the engagement of the threaded sleeve. The base plate mechanism can be rotated and positioned by the linkage rotation of the locking rod. It is easy to operate and facilitates the folding, transportation, and unfolding of the device.

[0004] In this prior art, the display is supported by an upper support column and a lower support column; however, since the upper support column and the lower support column are located outside the display, the center of gravity of the upper support column and the lower support column will not be on the same plane as the center of gravity of the display, which can easily cause the display to tilt, thereby reducing the stability of the product. Summary of the Invention

[0005] To address the problem in existing technologies where the upper and lower support pillars are not aligned with the center of gravity of the display, potentially causing the display to tilt and reducing product stability, this invention provides an anti-tipping folding display device. This device employs two support rods aligned with the center of gravity of the first and second mounting frames on the same plane. By positioning the two support rods outside the first and second mounting frames, the device prevents the first and second mounting frames from tipping over due to instability, thus improving product stability. The specific technical solution is as follows: An anti-tipping and folding display device includes four display screen bodies. The device comprises a base, uprights, a crossbeam, a first mounting frame, a second mounting frame, a third mounting frame, a fourth mounting frame, and a support rod.

[0012] In the above technical solution, the anti-tipping and folding display device further includes: a second connecting seat, an optical axis, a mounting seat, a second connecting frame, and a second support beam; the second connecting seats are respectively installed on the side wall of a column, and the second connecting seats are located below the display body; the optical axis passes through the second connecting seat; the mounting seats are respectively connected to the optical axis, and the mounting seats are located below the two second connecting seats; the second connecting frame is L-shaped, and the second connecting frame is connected to the side wall of the mounting seat; the second support beam is connected to the bottom of the second connecting frame.

[0015] The anti-tipping folding display device of the present invention has the following advantages compared with the prior art: 1. By simultaneously connecting two support rods to the first and second mounting frames, the two support rods connect the first and second mounting frames together, enabling the first and second mounting frames to move up and down synchronously. By positioning one end of each support rod within the second mounting frame and allowing the two support rods to pass sequentially through the first mounting frame and the crossbeam, the crossbeam supports the first and second mounting frames via the two support rods, thereby improving the stability of the first and second mounting frames. This ensures that when the first and second mounting frames move up and down, the two support rods can move up and down within the crossbeam, preventing the first and second mounting frames from shifting during vertical movement, and thus improving the stability of the first and second mounting frames and the display screen body installed within them during vertical movement. Because the two support rods are located within the first and second mounting frames, their centers of gravity are on the same plane as the first and second mounting frames. This is in contrast to placing the two support rods outside the first and second mounting frames (where their centers of gravity are not on the same plane). This prevents the first and second mounting frames from tipping over due to instability, thus improving product stability. Furthermore, since the two support rods are connected to both the first and second mounting frames, they can be positioned and corrected. This ensures that when the two display screens are installed within the first and second mounting frames, they are on the same plane, improving the display effect. Moreover, because the crossbeam positions the first and second mounting frames via the two support rods, when the third and fourth mounting frames rotate upwards, they are all on the same plane, ensuring that all four display screens are on the same plane, further enhancing the product's display effect.

[0016] 2. By connecting the two sliders to the two first connecting seats respectively, and allowing the two slide rails to pass through the slide grooves of the two sliders respectively, the support rod can move up and down along the slide rails via the sliders, thereby improving the stability of the support rod, the first mounting frame and the second mounting frame moving up and down, and thus improving the stability of the four display screen bodies moving up and down.

[0017] 3. By installing two guide seats at the bottom of the crossbeam and having the two guide seats respectively wrapped around the outside of the two support rods, the crossbeam supports the two guide seats, thereby enabling the two guide seats to support the two support rods respectively, further improving the stability of the two support rods, the first mounting frame and the second mounting frame in vertical movement, and thus improving the stability of the four display screen bodies in vertical movement.

[0018] 4. By passing at least four first set screws through four first connectors and abutting the at least four first set screws with the two support rods respectively, the two support rods are installed in the first mounting frame, thereby enabling the two support rods to move up and down synchronously with the first mounting frame; by passing at least four second set screws through four second connectors and abutting the at least four second set screws with the two support rods respectively, the two support rods are installed in the second mounting frame, thereby enabling the two support rods to move up and down synchronously with the second mounting frame.

[0019] 5. By setting the second locating pin and the second locating hole to an overfit, when the second locating pin is embedded in the second locating hole, it can be prevented from easily moving out of the second locating hole, thereby enabling the first and second mounting frames to fit with the third and fourth mounting frames. This, in turn, prevents the first and second mounting frames from separating from the third and fourth mounting frames during product transportation, thus improving the stability of product transportation.

[0020] 6. By setting multiple first positioning holes at the bottom of the third mounting frame, connecting multiple first positioning pins to the top of the second mounting frame, and aligning the multiple first positioning pins with the multiple first positioning holes respectively, the first positioning pins can be embedded in the first positioning holes when the third mounting frame rotates upward. This allows the second mounting frame to position and correct the third mounting frame through the multiple first positioning pins, further ensuring that the four display screen bodies are on the same plane, thereby improving the product's display effect.

[0021] 7. When preparing to move the product, and with the third and fourth mounting frames folded, tilt the product away from the display screen body so that the moving wheels contact the ground, thereby enabling the product to be moved by the moving wheels, reducing the difficulty of moving the product and improving its mobility.

[0022] 8. Before use, the second support beam is placed on the base, allowing the base to support it and reducing the product's footprint, thus avoiding the need for moving and storing the product. When ready to use, simply rotate the second support beam to remove it from the base. Gravity causes the beam to move downwards and contact the ground, providing support and improving stability. Because the second connector and support beam are located below the display screen, when the product is unfolded, it tilts slightly towards the second support beam, ensuring it contacts the ground and provides support, further enhancing stability.

[0023] 9. By passing two third set screws through both sides of the second connecting seat and simultaneously engaging the two third set screws with the optical axis, the two third set screws can fix the optical axis inside the second connecting seat when the second support beam is placed on the ground, thereby preventing the optical axis from rotating or moving inside the second connecting seat, thus improving the stability of the second support beam and the overall stability of the product.

[0024] 10. By simultaneously connecting the first sealing plate assembly to the side wall of the crossbeam opposite to the display screen body and the side walls of the two columns opposite to the display screen body, and placing the fourth mounting frame on top of the first sealing plate assembly, the first sealing plate assembly can enclose one side of the crossbeam and the two columns, thereby improving the product's aesthetics. Simultaneously, the first sealing plate assembly can also support the fourth mounting frame, thus improving its stability. By simultaneously connecting the second sealing plate assembly to the side wall of the crossbeam near the display screen body and the side walls of the two columns near the display screen body, the second sealing plate assembly can enclose the other side of the crossbeam and the two columns, further improving the product's aesthetics.

Detailed Implementation

[0026] The following are specific implementation cases and appendices. Figures 1 to 8 The present invention will be further described, but the present invention is not limited to these embodiments.

[0027] An anti-tipping folding display device, such as Figures 1 to 8As shown, the anti-tipping and folding display device includes four display screen bodies 10. The anti-tipping and folding display device includes: a base 11, columns 12, a crossbeam 13, a first mounting frame 14, a second mounting frame 15, a third mounting frame 16, a fourth mounting frame 17, and a support rod 18. Two columns 12 are vertically mounted on the base 11, with a gap between them. The crossbeam 13 is connected to the tops of both columns 12 and is perpendicular to the columns 12. The first mounting frame 14 is a hollow cavity with openings in its sidewalls, and is placed on the crossbeam 13. The second mounting frame 15 is also a hollow cavity with openings in its sidewalls, and its bottom is rotatably connected to the top of the first mounting frame 14. The third mounting frame... 16 is a hollow cavity with an opening in the side wall, and the bottom of the third mounting frame 16 is rotatably connected to the top of the second mounting frame 15; the fourth mounting frame 17 is a hollow cavity with an opening in the side wall, and the bottom of the fourth mounting frame 17 is connected to the top of the third mounting frame 16; one end of the two support rods 18 is located inside the second mounting frame 15, and the two support rods 18 pass through the first mounting frame 14 and the crossbeam 13 in sequence, and the other end of the two support rods 18 is located below the crossbeam 13, and the two support rods 18 are simultaneously connected to the first mounting frame 14 and the second mounting frame 15; wherein, the four display screen bodies 10 are respectively installed in the side wall openings of the first mounting frame 14, the second mounting frame 15, the third mounting frame 16 and the fourth mounting frame 17.

[0028] By vertically mounting two columns 12 on the base 11 and connecting the crossbeam 13 to the top of both columns 12, the two columns 12 support the crossbeam 13, thus forming a stable frame structure with the crossbeam 13, the two columns 12, and the base 11, thereby improving the overall strength of the product. By placing the first mounting frame 14 on the crossbeam 13 and rotatably connecting the bottom of the second mounting frame 15 to the top of the first mounting frame 14, the crossbeam 13 supports the first mounting frame 14, allowing the first mounting frame 14 and the second mounting frame 15 to rotate relative to each other. By rotatably connecting the bottom of the third mounting frame 16 to the top of the second mounting frame 15 and connecting the bottom of the fourth mounting frame 17 to the top of the third mounting frame 16, the second mounting frame 15 supports the third mounting frame 16, allowing the third mounting frame 16 and the second mounting frame 15 to rotate relative to each other, while also allowing the third mounting frame 16 to support the fourth mounting frame 17. By positioning one end of each of the two support rods 18 within the second mounting frame 15, passing the two support rods 18 sequentially through the first mounting frame 14 and the crossbeam 13, and simultaneously connecting the two support rods 18 to both the first mounting frame 14 and the second mounting frame 15, the first mounting frame 14 and the second mounting frame 15 are connected together via the support rods 18. This allows the crossbeam 13 to support the first mounting frame 14 and the second mounting frame 15 via the two support rods 18, thereby improving the stability of the first mounting frame 14 and the second mounting frame 15. By installing the four display screen bodies 10 respectively within the side wall openings of the first mounting frame 14, the second mounting frame 15, the third mounting frame 16, and the fourth mounting frame 17, the first mounting frame 14, the second mounting frame 15, the third mounting frame 16, and the fourth mounting frame 17 respectively support and accommodate the four display screen bodies 10.

[0029] When the product is used, when it is moved to the predetermined position, the third mounting frame 16 and the fourth mounting frame 17 are rotated so that the first mounting frame 14, the second mounting frame 15, the third mounting frame 16 and the fourth mounting frame 17 are in a plane, thereby making the four display screen bodies 10 in the same plane to increase the display area of ​​the product; when it is time to move the product, the third mounting frame 16 and the fourth mounting frame 17 are rotated so that the third mounting frame 16 and the fourth mounting frame 17 are folded relative to the first mounting frame 14 and the second mounting frame 15, thereby reducing the space occupied by the product and making it easier to move the product.

[0030] By adopting the above structure, by connecting two support rods 18 simultaneously to the first mounting frame 14 and the second mounting frame 15, the two support rods 18 connect the first mounting frame 14 and the second mounting frame 15 together, thereby enabling the first mounting frame 14 and the second mounting frame 15 to move up and down synchronously. By placing one end of each support rod 18 inside the second mounting frame 15 and having each support rod 18 pass through the first mounting frame 14 and the crossbeam 13 in sequence, the crossbeam 13 supports the first mounting frame 14 and the second mounting frame 15 through the two support rods 18, thereby improving the stability of the first mounting frame 14 and the second mounting frame 15. This ensures that when the first mounting frame 14 and the second mounting frame 15 move up and down, the two support rods 18 can move up and down within the crossbeam 13, preventing the first mounting frame 14 and the second mounting frame 15 from shifting during up and down movement, and thus improving the stability of the first mounting frame 14, the second mounting frame 15, and the display screen body 10 installed within the first mounting frame 14 and the second mounting frame 15 during up and down movement. Since the two support rods 18 are located inside the first mounting frame 14 and the second mounting frame 15, the centers of gravity of the two support rods 18 and the first mounting frame 14 and the second mounting frame 15 are on the same plane. Compared to placing the two support rods 18 outside the first mounting frame 14 and the second mounting frame 15 (in which case the centers of gravity of the two support rods 18 and the first mounting frame 14 and the second mounting frame 15 are not on the same plane), this can prevent the first mounting frame 14 and the second mounting frame 15 from tipping over due to instability, thus improving the stability of the product. At the same time, since the two support rods 18 are connected to both the first mounting frame 14 and the second mounting frame 15, they can provide support for the first mounting frame. The first mounting frame 14 and the second mounting frame 15 are positioned and corrected to ensure that when the two display screen bodies 10 are respectively installed in the first mounting frame 14 and the second mounting frame 15, the two display screen bodies 10 are on the same plane, thereby improving the display effect of the product. Moreover, since the crossbeam 13 positions the first mounting frame 14 and the second mounting frame 15 through the two support rods 18, when the third mounting frame 16 and the fourth mounting frame 17 rotate upward, it can ensure that the first mounting frame 14, the second mounting frame 15, the third mounting frame 16 and the fourth mounting frame 17 are on the same plane, thereby ensuring that the four display screen bodies 10 are on the same plane, further improving the display effect of the product.

[0031] In embodiments of the present invention, such as Figures 1 to 8As shown, the anti-tipping folding display device also includes: slide rails 19, first connecting seats 20, and sliders 21; the two slide rails 19 are respectively installed on one side wall of the two columns 12; the two first connecting seats 20 are respectively connected to the other end of the two support rods 18, and the two first connecting seats 20 are respectively located on one side of the two slide rails 19; the slider 21 is provided with a sliding groove, the two sliders 21 are respectively connected to the two first connecting seats 20, and the two slide rails 19 pass through the sliding grooves of the two sliders 21 respectively.

[0032] By installing two slide rails 19 on one side wall of two columns 12 respectively, the two columns 12 support the two slide rails 19 respectively, thereby improving the stability of the two slide rails 19; by connecting the two first connecting seats 20 to the other end of the two support rods 18 respectively, the two support rods 18 and the two first connecting seats 20 move up and down synchronously; by connecting the two sliders 21 to the two first connecting seats 20 respectively, and letting the two slide rails 19 pass through the grooves of the two sliders 21 respectively, the support rods 18 move up and down along the slide rails 19 through the sliders 21, thereby improving the stability of the up and down movement of the support rods 18, the first mounting frame 14 and the second mounting frame 15, and thus improving the stability of the up and down movement of the four display screen bodies 10.

[0034] By installing two guide seats 22 at the bottom of the crossbeam 13 and having the two guide seats 22 respectively wrapped around the outside of the two support rods 18, the crossbeam 13 supports the two guide seats 22, thereby enabling the two guide seats 22 to support the two support rods 18 respectively, further improving the stability of the two support rods 18, the first mounting frame 14 and the second mounting frame 15 in vertical movement, and thus improving the stability of the four display screen bodies 10 in vertical movement.

[0036] By installing four first connecting brackets 30 inside the first mounting frame 14, and having four first connecting members 23 respectively wrapped around the outside of the two support rods 18, the first mounting frame 14 supports the four first connecting members 23. By passing at least four first set screws through the four first connecting members 23 and having the at least four first set screws respectively abutting against the two support rods 18, the two support rods 18 are installed inside the first mounting frame 14, thereby enabling the two support rods 18 to move up and down synchronously with the first mounting frame 14. By installing four second connecting brackets 36 inside the second mounting frame 15, and having four second connecting members 24 respectively wrapped around the outside of the two support rods 18, the second mounting frame 15 supports the four second connecting members 24. By passing at least four second set screws through the four second connecting members 24 and having the at least four second set screws respectively abutting against the two support rods 18, the two support rods 18 are installed inside the second mounting frame 15, thereby enabling the two support rods 18 to move up and down synchronously with the second mounting frame 15.

[0037] In embodiments of the present invention, such as Figures 1 to 8 As shown, the anti-tipping folding display device further includes: a first positioning hole 25 and a first positioning pin 26; at least two first positioning holes 25 are disposed at the bottom of the third mounting frame 16; at least two first positioning pins 26 are connected to the top of the second mounting frame 15, and at least two first positioning pins 26 are respectively opposite to at least two first positioning holes 25.

[0038] By setting multiple first positioning holes 25 at the bottom of the third mounting frame 16 and connecting multiple first positioning pins 26 to the top of the second mounting frame 15, and making the multiple first positioning pins 26 respectively opposite to the multiple first positioning holes 25, the first positioning pins 26 can be embedded in the first positioning holes 25 when the third mounting frame 16 rotates upward. This allows the second mounting frame 15 to position and correct the third mounting frame 16 through the multiple first positioning pins 26, further ensuring that the four display screen bodies 10 are on the same plane, thereby improving the display effect of the product.

[0039] In embodiments of the present invention, such as Figures 1 to 8 As shown, the anti-tipping folding display device further includes: a second positioning hole and a second positioning pin 28; at least two second positioning holes are disposed on the top of the side wall of the fourth mounting frame 17; at least two second positioning pins 28 are connected to the bottom of the side wall of the first mounting frame 14, and at least two second positioning pins 28 are respectively opposite to at least two second positioning holes; wherein, the second positioning pins 28 and the second positioning holes are overfitted.

[0040] By setting multiple second positioning holes on the top of the side wall of the fourth mounting frame 17, connecting multiple second positioning pins 28 to the bottom of the side wall of the first mounting frame 14, and positioning the multiple second positioning pins 28 opposite to the multiple second positioning holes respectively, the multiple second positioning pins 28 can be inserted into the multiple second positioning holes respectively when the third mounting frame 16 and the fourth mounting frame 17 rotate downwards, thereby positioning the first mounting frame 14 for the fourth mounting frame 17. By setting the second positioning pins 28 and the second positioning holes to an overfit, the second positioning pins 28 can be prevented from easily moving out of the second positioning holes when they are inserted, thereby allowing the first mounting frame 14 and the second mounting frame 15 to fit closely with the third mounting frame 16 and the fourth mounting frame 17. This prevents the first mounting frame 14 and the second mounting frame 15 from separating from the third mounting frame 16 and the fourth mounting frame 17 during product transportation, thus improving the stability of product transportation.

[0041] In embodiments of the present invention, such as Figures 1 to 8 As shown, the anti-tipping and folding display device also includes: a first support beam 29, a first connecting frame 30, a rotating shaft 31, and a moving wheel 32; the two first support beams 29 are connected to the side wall of the base 11 away from the display body 10, and there is a gap between the two first support beams 29; the first connecting frame 30 is L-shaped, and the two first connecting frames 30 are respectively connected to the two columns 12, and the two first connecting frames 30 are respectively located on one side of the first support beam 29; the two ends of the rotating shaft 31 are respectively connected to the first support beam 29 and the first connecting frame 30; the moving wheel 32 is fitted on the outside of the rotating shaft 31.

[0042] By connecting the two first support beams 29 to the side wall of the base 11 away from the display screen body 10, and connecting the two first connecting frames 30 to the two columns 12 respectively, the base 11 can support the two first support beams 29, thereby enabling the columns 12 to support the first connecting frames 30, thus improving the stability of the two first support beams 29 and the two first connecting frames 30; by connecting the two ends of the rotating shaft 31 to the first support beams 29 and the first connecting frames 30 respectively, and fitting the moving wheels 32 on the outside of the rotating shaft 31, the first support beams 29 and the first connecting frames 30 cooperate to support the rotating shaft 31, thereby enabling the rotating shaft 31 to support the moving wheels 32.

[0043] With the above structure, when preparing to move the product and the third mounting frame 16 and the fourth mounting frame 17 are folded, the product is tilted away from the display screen body 10, so that the moving wheel 32 contacts the ground, thereby realizing the movement of the product by the moving wheel 32, reducing the difficulty of moving the product and improving the mobility of the product.

[0044] Specifically, when the product is in normal use, the caster 32 does not come into contact with the ground.

[0045] In embodiments of the present invention, such as Figures 1 to 8 As shown, the anti-tipping and folding display device further includes: a second connecting seat 33, an optical axis 34, a mounting seat 35, a second connecting frame 36, and a second support beam 37; the second connecting seats 33 are respectively installed on the side wall of one of the columns 12, and the second connecting seats 33 are located below the display body 10; the optical axis 34 passes through the second connecting seat 33; the mounting seats 35 are respectively connected to the optical axis 34, and the mounting seats 35 are located below the two second connecting seats 33; the second connecting frame 36 is L-shaped, and the second connecting frame 36 is connected to the side wall of the mounting seat 35; the second support beam 37 is connected to the bottom of the second connecting frame 36.

[0046] By mounting the second connecting seat 33 on the side wall of a column 12 and allowing the optical axis 34 to pass through the second connecting seat 33, the column 12 can support the second connecting seat 33, thereby enabling the optical axis 34 to move and rotate within the second connecting seat 33. By connecting the mounting base 35 to the optical axis 34 and connecting the second support beam 37 to the mounting base 35, the optical axis 34 can drive the second support beam 37 to move and rotate through the mounting base 35, thereby enabling the second support beam 37 to be placed on the ground, thus supporting the product and improving its stability.

[0047] With the above structure, before the product is ready to be used, the second support beam 37 is placed on the base 11, thereby supporting the second support beam 37 from the base 11. This also reduces the space occupied by the product, avoiding the need for moving and storing it. When the product is ready to be used, simply rotate the second support beam 37, causing it to move off the base 11. The second support beam 37 then moves downwards due to gravity, contacting the ground and thus supporting the product and improving its stability. Since the second connecting seat 33 and the second support beam 37 are located below the display screen body 10, when the product is unfolded, the entire product will tilt slightly towards the second support beam 37, ensuring that the second support beam 37 can contact the ground and support the product, further enhancing its stability.

[0048] In embodiments of the present invention, such as Figures 1 to 8 As shown, the anti-tipping folding display device also includes: a third set screw 38, a handwheel 39, an external thread, and a limiting nut 40; the two third set screws 38 pass through both sides of the second connecting seat 33 respectively, and the two third set screws 38 are simultaneously in contact with the optical axis 34; the two handwheels 39 are respectively connected to the ends of the two third set screws 38 away from the second connecting seat 33; the external thread is provided on the outer wall of the end of the optical axis 34 away from the mounting seat 35; the limiting nut 40 is provided with an internal thread, the limiting nut 40 is fitted on the outside of the optical axis 34, the limiting nut 40 is located above the second connecting seat 33, and the limiting nut 40 is opposite to the second connecting seat 33; wherein, the external thread and the internal thread are adapted to each other.

[0049] By passing two third set screws 38 through both sides of the second connecting seat 33 and simultaneously engaging the two third set screws 38 with the optical axis 34, the optical axis 34 can be fixed within the second connecting seat 33 when the second support beam 37 is placed on the ground. This prevents the optical axis 34 from rotating or moving within the second connecting seat 33, thereby improving the stability of the second support beam 37 and the overall stability of the product. By setting the external thread on the outer wall of the optical axis 34 and fitting a limiting nut 40 onto the outside of the optical axis 34, with the limiting nut 40 facing the second connecting seat 33, a threaded connection is achieved between the optical axis 34 and the limiting nut 40. This ensures that when the end of the optical axis 34 moves to the second connecting seat 33, the limiting nut 40 engages with the second connecting seat 33, preventing the optical axis 34 from moving out of the second connecting seat 33 and improving the user experience.

[0050] In embodiments of the present invention, such as Figures 1 to 8As shown, the anti-tipping folding display device further includes: a first sealing plate assembly 41 and a second sealing plate assembly 42; the first sealing plate is simultaneously connected to the side wall of the crossbeam 13 away from the display body 10 and the side wall of the two columns 12 away from the display body 10, and the fourth mounting frame 17 is placed on top of the first sealing plate assembly 41; the second sealing plate assembly 42 is simultaneously connected to the side wall of the crossbeam 13 near the display body 10 and the side wall of the two columns 12 near the display body 10.

[0051] By simultaneously connecting the first sealing plate assembly 41 to both the side wall of the crossbeam 13 facing away from the display screen body 10 and the side walls of the two columns 12 facing away from the display screen body 10, and placing the fourth mounting frame 17 on top of the first sealing plate assembly 41, the first sealing plate assembly 41 can enclose one side of the crossbeam 13 and the two columns 12, thereby improving the aesthetics of the product. Simultaneously, the first sealing plate assembly 41 can also support the fourth mounting frame 17, thus improving the stability of the fourth mounting frame 17. By simultaneously connecting the second sealing plate assembly 42 to both the side wall of the crossbeam 13 near the display screen body 10 and the side walls of the two columns 12 near the display screen body 10, the second sealing plate assembly 42 can enclose the other side of the crossbeam 13 and the two columns 12, further improving the aesthetics of the product.
