Detailed implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , the present invention discloses a rotary liquid crystal display, including a bottom plate 1. A rotating mechanism 2 is fixedly installed at a position near the middle of the upper surface of the bottom plate 1. A first cylinder 3 is fixedly installed on the upper surface of the rotating mechanism 2. Telescopic rods 5 are installed on the front and rear sides of the first cylinder 3 through a first locking assembly 4, and a second cylinder 7 is installed between the upper ends of the front and rear telescopic rods 5 through a second locking assembly 6. Both the first locking assembly 4 and the second locking assembly 6 are composed of a bolt rod and a nut. Through holes for the passage of the functional bolt rod are provided on both the first cylinder 3 and the second cylinder 7. A mounting bracket 8 is fixedly installed on the left side surface of the second cylinder 7. A housing 9 is fixedly installed on the right side surface of the mounting bracket 8. A display screen main body 10 is embedded in the upper side position of the right side wall of the housing 9. Air inlet holes 11 are evenly provided on the lower side wall of the housing 9. A heat dissipation mechanism 12 is arranged between the front and rear inner walls of the housing 9 corresponding to the air inlet holes 11.

[0021] Specifically, the rotating mechanism 2 includes a damping sleeve assembly 201, a rotating shaft 202, and a first locking bolt 203. The damping sleeve assembly 201 is fixedly installed in the bottom plate 1. A rotating shaft 202 is snap-fitted in the damping sleeve assembly 201, and the upper surface of the rotating shaft 202 is fixedly connected to the lower surface of the first cylinder 3. A first locking bolt 203 is threadedly installed on the right side wall of the damping sleeve assembly 201 corresponding to the rotating shaft 202, and the first locking bolt 203 locks and fixes the damping sleeve assembly 201 and the rotating shaft 202.

[0022] In this implementation scheme, by tightening or loosening the first locking bolt 203, the rotating shaft 202 rotates within the damping sleeve assembly 201, achieving the effect of rotating and adjusting the display body 10 within the housing 9.

[0023] Specifically, the telescopic rod 5 includes a first sleeve 401, a second locking bolt 402, and a second sleeve 403. The first sleeve 401 is clamped between the first locking assembly 4 and the first cylinder 3. The second sleeve 403 is installed on the upper surface of the first sleeve 401 through the second locking bolt 402, and the second sleeve 403 is clamped between the second locking assembly 6 and the end of the second cylinder 7.

[0024] In this implementation scheme, by tightening or loosening the second locking bolt 402, the second sleeve 403 moves up and down within the first sleeve 401, achieving the effect of adjusting the height of the display body 10 within the housing 9.

[0025] Specifically, the heat dissipation mechanism 12 includes a filter element 121, an electric linear module 122, a grid plate 123, a fan 124, and a one-way exhaust valve 125. The filter element 121 is inserted into the housing 9. The electric linear module 122 is installed between the front and rear inner walls of the housing 9 above the filter element 121. The grid plate 123 is fixedly installed on the upper surface of the slide table of the electric linear module 122. The fan 124 is installed on the upper surface of the grid plate 123. The one-way exhaust valves 125 are installed at the front and rear edges of the upper side of the left side wall of the housing 9.

[0026] In this implementation scheme, the filter element 121 prevents external rainwater and dust from entering the housing 9 through the air inlet holes 11. The slide table of the electric linear module 122 drives the fan 124 on the grid plate 123 to reciprocate back and forth, enabling the fan 124 to cover a wider area of the entire display body 10, allowing the hot air to be discharged through the one-way exhaust valve 125. The filter element 121 is composed of a filter mesh and a waterproof and breathable membrane.

[0027] Specifically, the length and width of the filter element 121 are the same as the length and width of the inner wall of the housing 9, and a rubber seal cover 13 is snap-fitted on the front side wall of the housing 9 corresponding to the filter element 121.

[0028] In this implementation scheme, the filter element 121 can be stably installed within the housing 9. By opening the rubber seal cover 13, it is convenient to clean or replace the filter element 121.

[0029] Specifically, the left side surface of the one-way exhaust valve 125 is perpendicular and flush with the left side surface of the housing 9.

[0030] In this implementation scheme, there is no protrusion between the one-way exhaust valve 125 and the housing 9, ensuring a beautiful appearance.

[0031] Specifically, sponge pads 14 are provided on the right side surfaces of the telescopic rods 5.

[0032] In this embodiment, the sponge pad 14 enhances the buffering function between the telescopic rod 5 and the display screen main body 10, making it less likely for the display screen main body 10 to be knocked and damaged.

[0033] During use, by loosening and tightening the first locking bolt 203 in the rotating mechanism 2, the rotating shaft 202 rotates within the damping sleeve assembly 201. The first cylinder 3 on the upper surface of the rotating shaft 202 has a rotating function, that is, the display screen main body 10 within the housing 9 has a rotating function. By loosening and tightening the first locking assembly 4, the telescopic rod 5 can be inclined along the first cylinder 3. Then, by loosening and tightening the second locking bolt 402 in the telescopic rod 5, the second sleeve 403 moves up and down within the first sleeve 401. The second sleeve 403 drives the second cylinder 7 to move, and the second cylinder 7 drives the mounting bracket 8 to move, achieving the effect of adjusting the height of the display screen main body 10 within the housing 9. By loosening and tightening the second locking assembly 6, the second cylinder 7 rotates between the front and rear telescopic rods 5, and the display screen main body 10 within the housing 9 is tilted again. Thus, the display can be rotated, tilted, and its height adjusted, and the display screen main body 10 can be folded and retracted along the telescopic rod 5, making the volume smaller and more convenient to carry. The display screen main body 10 is less likely to be knocked and damaged. Through the filter element 121 in the heat dissipation mechanism 12, external rainwater and dust are prevented from entering the housing 9 through the air intake hole 11. The slide of the electric linear module 122 drives the fan 124 on the grid plate 123 to reciprocate back and forth, enabling the fan 124 to cover a wider area of the entire display screen main body 10, allowing the hot air to be discharged through the one-way exhaust valve 125, improving the heat dissipation effect of the display screen main body 10, making the heat dissipation more comprehensive, effectively preventing external rainwater from entering, and facilitating use.

[0034] In summary, this rotary liquid crystal display can rotate, tilt, and adjust the height of the display, and can fold and retract the display screen main body 10, making the volume smaller and more convenient to carry. The display screen main body 10 is less likely to be knocked and damaged, improving the heat dissipation effect of the display screen main body 10, preventing external rainwater from entering, and facilitating use.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
