Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a rotatable LED display. Background Technology

[0002] An LED display screen is an electronic display device that uses light-emitting diodes (LEDs) to display images, text, videos, and other information. A bracket is often installed at the bottom of the LED display screen, and the top of the bracket is usually connected to the LED display screen through a cylindrical rotary damper. The cylindrical rotary damper is used to adjust the pitch angle of the LED display screen and achieve self-locking after the angle adjustment is completed.

[0003] In common rotatable LED displays, the bracket is connected to the LED display via a cylindrical rotary damper. The cylindrical rotary damper is used to adjust the tilt angle of the LED display and achieve self-locking after the angle adjustment is completed. However, when users conduct desktop video conferences, they need to turn the display towards participants in different directions to ensure that the other party can clearly see the screen content. Existing adjustment methods can only adjust the tilt angle of the display, and it is usually difficult to adjust the horizontal angle. This limits the application flexibility of LED displays in desktop scenarios and makes it difficult to meet diverse usage needs. Therefore, this application provides a rotatable LED display to meet these needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rotatable LED display screen to solve the problem that the horizontal angle adjustment of LED display screens is usually difficult to achieve, thus limiting the application flexibility of LED display screens in desktop scenarios and making it difficult to meet diverse usage needs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A rotatable LED display screen includes a display screen body and further includes:

[0007] The horizontal rotation mechanism includes a vertical plate rotatably connected to the bottom of the display screen body. A connecting seat is fixed to the bottom of the vertical plate. A box-type base is provided below the connecting seat. A disc-type rotary damper and a positioning ring are fixed to the top of the box-type base. A rotating seat is rotatably connected to the inner wall of the positioning ring. The inner wall of the rotating seat is slidably connected to the outer wall of the connecting seat. A square pin is fixed to the top of the inner wall of the connecting seat. The square pin is inserted into the interior of the disc-type rotary damper. A locking device is provided on the outer wall of the connecting seat for locking connection between the connecting seat and the rotating seat.

[0008] Preferably, the locking component includes a block fixed to the outer wall of the connecting seat, and a square groove is provided on the top of the rotating seat, in which the block is locked.

[0009] Preferably, the outer wall of the connecting seat is fixed with a main spring piece, the bottom of the block is provided with a groove, the main spring piece is located in the groove, the bottom of the main spring piece is fixed with a card plate, the bottom of the inner wall of the square groove is provided with a card slot, the side of the inner wall of the card slot is provided with a V-shaped surface, and the V-shaped surface is in contact with the side of the card plate away from the connecting seat.

[0010] Preferably, the main spring sheet has a notch on its side, and an auxiliary spring sheet is fixed to the inner wall of the notch. The side of the auxiliary spring sheet abuts against the outer wall of the connecting seat.

[0011] Preferably, the bottom of the auxiliary spring sheet is provided with a winding part, which abuts against the outer wall of the connecting seat.

[0012] Preferably, the card plate includes a V-shaped part and a bent part connected sequentially from top to bottom. The top of the V-shaped part is fixedly connected to the bottom of the main spring piece. A protrusion is provided on the side of the bent part near the connecting seat. A sliding groove is provided at the bottom of the connecting seat. The top of the protrusion is slidably connected to the inner wall of the sliding groove. The V-shaped part fits against the V-shaped surface.

[0013] Preferably, the protrusion is provided with a curved surface at the point where it fits against the inner wall of the groove.

[0014] Preferably, the connecting seat is polygonal, and the shape of the rotating seat is adapted to the shape of the connecting seat.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, by setting up a connecting seat, a square pin, and a disc-type rotary damper, when adjusting the angle of the display screen body in the horizontal direction, rotating the display screen body causes the vertical plate to rotate, which in turn causes the square pin to rotate within the disc-type rotary damper. This achieves the adjustment of the horizontal angle of the display screen body and its self-locking, improving the application flexibility of LED displays in desktop scenarios and meeting diverse usage needs.

[0017] With the main spring and the locking plate, when the connector is inserted into the rotating seat, the locking plate is driven by the elastic force of the main spring to fit against the V-shaped surface, realizing the locking connection between the connector and the rotating seat. At the same time, the block is locked in the square groove to prevent the connector and the rotating seat from being misaligned in the horizontal direction, so that the connection between the connector and the rotating seat is more stable and reliable, thereby ensuring the stable horizontal rotation of the display body.

[0018] By incorporating auxiliary spring sheets and a winding section, the auxiliary spring sheets deform synchronously when the main spring sheet is subjected to force and deformation. The auxiliary spring sheets increase the elasticity of the main spring sheet, distributing the force on the main spring sheet to the auxiliary spring sheets and preventing the main spring sheet from being subjected to force alone, thereby increasing the service life of the main spring sheet. Furthermore, the auxiliary spring sheets abut against the outer wall of the connecting seat through the winding section, which increases the wear resistance of the auxiliary spring sheets, thus further extending their service life.

[0019] By incorporating the protrusions and grooves, when the card plate is initially inserted into the slot, the side of the inner wall of the slot presses against the V-shaped portion on the card plate, causing the V-shaped portion to rotate towards the connecting seat and deform the main spring piece. Simultaneously, the V-shaped portion drives the protrusion to slide along the inner wall of the groove. The cooperation between the protrusion and the groove prevents the V-shaped portion from tilting upwards when the side of the inner wall of the slot presses against it, ensuring that the V-shaped portion rotates stably towards the connecting seat. This prevents the V-shaped portion from excessively compressing the main spring piece when it moves upwards under pressure, further improving the service life of the main spring piece.

Detailed Implementation

[0030] The rotatable LED display screen provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0031] like Figures 1-6 As shown, an embodiment of this utility model provides a rotatable LED display screen, including a display screen body 1, and further comprising:

[0032] The horizontal rotation mechanism 2 includes a vertical plate 3 rotatably connected to the bottom of the display body 1. The vertical plate 3 is rotatably connected to the display body 1 via a cylindrical rotary damper. The cylindrical rotary damper is used to adjust the pitch angle of the display body 1. A connecting seat 4 is fixed to the bottom of the vertical plate 3. A box-type base 20 is provided below the connecting seat 4. The box-type base 20 can be used to store keyboards, mice, etc., thereby keeping the desktop where the display body 1 is located tidy. A disc-type rotary damper 6 and a positioning ring 7 are fixed to the top of the box-type base 20. A rotating seat 5 is rotatably connected to the inner wall of the positioning ring 7. The outer wall of the rotating seat 5 has a protruding ring, which is rotatably connected inside the positioning ring 7, thereby realizing the rotatable connection between the rotating seat 5 and the positioning ring 7 and preventing the rotating seat 5 from separating from the positioning ring 7. The inner wall of the rotating seat 5 is slidably connected to the outer wall of the connecting seat 4. A square pin 21 is fixed to the top of the inner wall of the connecting seat 4. 21 is inserted into the interior of the disc-type rotary damper 6. The outer wall of the connecting seat 4 is provided with a locking piece 8, which is used for the locking connection between the connecting seat 4 and the rotating seat 5. The vertical plate 3 realizes the rotational connection between the display body 1 and the connecting seat 4. When the display body 1 is rotated, the vertical plate 3 drives the connecting seat 4 to rotate. The connecting seat 4 drives the rotating seat 5 to rotate stably along the inner wall of the positioning ring 7. At the same time, the connecting seat 4 drives the square pin 21 to rotate inside the disc-type rotary damper 6. The damping force provided by the disc-type rotary damper 6 makes the display body 1 rotate smoothly and can achieve self-locking after being adjusted to a suitable angle to ensure the angle of the display body 1 is fixed. When conducting desktop video conferencing, the display body 1 can be turned to different directions of the participants, thereby ensuring that the other party can clearly see the screen content. The locking piece 8 is used for the locking of the connecting seat 4 and the rotating seat 5 to ensure that the connection between the two is firm and to prevent separation during rotation.

[0033] like Figure 2 and Figure 3 As shown, in this embodiment, the clip 8 includes a block 9 fixed to the outer wall of the connecting seat 4. The top of the rotating seat 5 is provided with a square groove 10. The block 9 is clipped in the square groove 10. When the connecting seat 4 and the rotating seat 5 are connected, the block 9 clipped in the square groove 10 can effectively prevent the two from being misaligned in the horizontal direction and enhance the stability of the connection between the two.

[0034] like Figure 3As shown, in this embodiment, a main spring piece 11 is fixed to the outer wall of the connecting seat 4, a groove is provided at the bottom of the block 9, the main spring piece 11 is located in the groove, a retaining plate 14 is fixed to the bottom of the main spring piece 11, a retaining groove 18 is provided at the bottom of the inner wall of the square groove 10, and a V-shaped surface 19 is provided on the side of the inner wall of the retaining groove 18. The V-shaped surface 19 is attached to the side of the retaining plate 14 away from the connecting seat 4. When the connecting seat 4 is inserted into the rotating seat 5, the side of the inner wall of the retaining groove 18 presses the retaining plate 14, causing the retaining plate 14 to rotate towards the connecting seat 4 and drive the main spring piece 11 to deform. When the block 9 is attached to the bottom of the square groove 10, the retaining plate 14 and the V-shaped surface 19 are in corresponding positions. Under the elastic force of the main spring piece 11, the retaining plate 14 and the V-shaped surface 19 are attached, realizing the snap-fit ​​connection between the connecting seat 4 and the rotating seat 5.

[0035] like Figure 3 and Figure 5 As shown, in this embodiment, a notch is provided on the side of the main spring piece 11, and an auxiliary spring piece 12 is fixed on the inner wall of the notch. The side of the auxiliary spring piece 12 abuts against the outer wall of the connecting seat 4. When the main spring piece 11 is deformed by force, the auxiliary spring piece 12 deforms synchronously. The auxiliary spring piece 12 can improve the elasticity of the main spring piece 11 and at the same time disperse the force on the main spring piece 11, so as to avoid the main spring piece 11 bearing too much force alone, thereby extending the service life of the main spring piece 11.

[0036] like Figure 3 and Figure 5 As shown, in this embodiment, the bottom of the auxiliary spring piece 12 is provided with a winding part 13. The winding part 13 abuts against the outer wall of the connecting seat 4. The winding part 13 can improve the wear resistance of the contact point between the auxiliary spring piece 12 and the outer wall of the connecting seat 4, reduce damage caused by long-term friction, extend the service life of the auxiliary spring piece 12, and ensure that the auxiliary spring piece 12 can continuously and stably assist the main spring piece 11 in working.

[0037] like Figure 3 and Figure 5 As shown, in this embodiment, the card plate 14 includes a V-shaped portion 15 and a bent portion 16 connected sequentially from top to bottom. The top of the V-shaped portion 15 is fixedly connected to the bottom of the main spring piece 11. The bent portion 16 has a protrusion 17 on the side near the connecting seat 4. The bottom of the connecting seat 4 has a sliding groove 22. The top of the protrusion 17 is slidably connected to the inner wall of the sliding groove 22. The V-shaped portion 15 fits against the V-shaped surface 19. During the process of inserting the card plate 14 into the card slot 18, the inner wall of the card slot 18 presses against the V-shaped portion 15. The rotation of the V-shaped portion 15 drives the protrusion 17 to slide along the inner wall of the sliding groove 22. Through the cooperation between the protrusion 17 and the sliding groove 22, the V-shaped portion 15 is prevented from tilting upwards, ensuring that the V-shaped portion 15 rotates stably towards the connecting seat 4, and avoiding the service life of the main spring piece 11 due to excessive pressure from the V-shaped portion 15.

[0038] like Figure 3As shown, in this embodiment, a curved surface is provided at the contact point between the protrusion 17 and the inner wall of the slide groove 22. The curved surface design can reduce the friction when the protrusion 17 slides against the inner wall of the slide groove 22, making the V-shaped part 15 rotate more smoothly, reducing wear caused by friction, and further improving the stability and reliability of the rotation of the clamping plate 14. At the same time, it automatically adapts to the change in angle when the V-shaped part 15 drives the protrusion 17 to rotate through the bending part 16, preventing jamming between the protrusion 17 and the slide groove 22.

[0039] like Figure 4 and Figure 6 As shown, in this embodiment, the connecting seat 4 is polygonal, and the shape of the rotating seat 5 is adapted to the shape of the connecting seat 4. The polygonal connecting seat 4 and the rotating seat 5 with the adapted shape can make the two contact more tightly when connected, and better transmit torque when the horizontal rotating mechanism 2 is working, avoid relative sliding, and ensure the stability and accuracy of the display screen body 1 in the horizontal direction.

[0040] Working principle: When it is necessary to adjust the angle of the display body 1 in the horizontal direction, rotate the display body 1. The display body 1 drives the connecting seat 4 to rotate through the vertical plate 3. The connecting seat 4 is connected to the rotating seat 5 through the clip 8. The connecting seat 4 drives the rotating seat 5 to rotate along the inner wall of the positioning ring 7. At the same time, the connecting seat 4 drives the square pin 21 to rotate in the disc-type rotary damper 6. The disc-type rotary damper 6 provides damping force, which makes the rotation of the display body 1 more stable on the one hand, and can achieve self-locking of the horizontal angle of the display body 1 when the appropriate angle is adjusted.

[0041] When connecting the connecting seat 4 into the rotating seat 5, align the connecting seat 4 and the rotating seat 5 and move the connecting seat 4 downwards. This causes the side of the inner wall of the slot 18 to press against the bottom of the V-shaped portion 15 of the card plate 14, causing the card plate 14 to rotate towards the connecting seat 4 and deform the main spring piece 11. When the main spring piece 11 deforms, it causes the auxiliary spring piece 12 to deform synchronously. When the V-shaped portion 15 rotates, the curved surface on the protrusion 17 rotates along the inner wall of the slide groove 22 through the bending portion 16. The cooperation between the protrusion 17 and the slide groove 22 prevents the side of the inner wall of the slot 18 from pressing against the V-shaped portion 15 and causing damage. The V-shaped part 15 is tilted upward to ensure that the V-shaped part 15 can rotate stably towards the connecting seat 4, and to prevent the V-shaped part 15 from excessively squeezing the main spring piece 11 when it is squeezed. When the block 9 is attached to the bottom of the inner wall of the square groove 10 at the top of the rotating seat 5, the positions of the V-shaped part 15 and the V-shaped surface 19 correspond to each other. Under the joint elastic force of the main spring piece 11 and the auxiliary spring piece 12, the V-shaped part 15 is stuck at the V-shaped surface 19, realizing the snap-fit ​​connection of the connecting seat 4 into the rotating seat 5, and the block 9 is stuck in the square groove 10 to prevent the connecting seat 4 and the rotating seat 5 from being misaligned in the horizontal direction.

[0042] During disassembly, pull the connecting seat 4 upward to make the connecting seat 4 drive the main spring plate 11 and the clamping plate 14 to move upward through the block 9. At this time, the V-shaped surface 19 presses the V-shaped part 15 of the clamping plate 14, causing the V-shaped part 15 to rotate towards the connecting seat 4 and separate from the V-shaped surface 19. After separation, pull the connecting seat 4 upward until the clamping plate 14 moves up to above the rotating seat 5. The connecting seat 4 and the rotating seat 5 are easy to disassemble, which facilitates the maintenance when the disc-type rotary damper 6 is damaged and the disassembly of the connecting seat 4 and the rotating seat 5 is convenient.

[0043] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
