Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to a rotating opening and closing LED display screen. Background Art

[0002] LED display is a new type of imaging electronic device made of light-emitting diodes arranged in sequence. Due to its high brightness, wide viewing angle, long life and other characteristics, it is being widely used in products such as outdoor advertising screens. Among the types of LED display screens, the movable sliding rail opening and closing LED display screen is a screen that opens and closes from the center of the stage to both sides. It is a more novel display method and brings a new experience.

[0003] However, the current movable slide rail opening and closing LED display screens using electric tracks and slides are mostly used for stage displays. They are tall and large in size. Before, during and after use, the display screen itself is prone to absorb dust, so the screen is very easy to be stained with dust. Long-term accumulation of dust will affect the viewing effect of people under the stage.

[0004] The existing patent (Announcement No.: CN219367363U) is a movable slide rail opening and closing LED display screen.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A rotating opening and closing LED display screen comprises a display screen body 1, a rotating opening and closing mechanism 2 for rotating and opening the display screen body 1 is arranged on one side of the display screen body 1, and a limiting component 3 for improving the stability of the display screen body 1 during rotation is arranged inside the rotating opening and closing mechanism 2;

[0031] The rotating opening and closing mechanism 2 includes a base plate 201, a turntable 202, a dual-output motor 203, a screw rod 204 and a moving plate 205. The base plate 201 is arranged below the display screen body 1, the turntable 202 is rotatably connected to the bottom of the base plate 201, the dual-output motor 203 is bolted to the top of the base plate 201, the screw rod 204 is fixedly connected to the two output ends of the dual-output motor 203, the moving plate 205 is threadedly connected to the outside of the screw rod 204, and the side wall of the moving plate 205 is bolted to the side wall of the display screen body 1.

[0032] Specifically, Figure 4 As shown, the top of the bottom plate 201 is bolted with a support frame 4, one end of the support frame 4 is bolted with a stabilizing plate 5, the side wall of the stabilizing plate 5 is tightly fitted with the side wall of the display screen body 1, and the top of the movable plate 205 is tightly fitted with the bottom of the stabilizing plate 5.

[0033] Specifically, Figure 1 As shown, a limiting groove 6 is opened on the side wall of the stabilizing plate 5 , a limiting plate 7 is bolted on the side wall of the display screen body 1 , and the limiting plate 7 is slidably connected to the limiting groove 6 .

[0034] Specifically, Figure 1 As shown, a baffle 8 for blocking the dual-output motor 203 is bolted to the side wall of the support frame 4, and the baffle 8 is made of stainless steel.

[0035] Specifically, Figure 1 As shown, four connecting plates 10 are welded on the outer wall of the turntable 202 , and screw grooves 12 are formed on the tops of the four connecting plates 10 .

[0036] Specifically, Figure 1As shown, a sealing ring 11 is bonded to the top of the turntable 202 , and the side wall of the sealing ring 11 is tightly fitted with the side wall of the bottom plate 201 .

[0037] When in use, first screw the external bolt into the inside of the screw groove 12 to fix the device. When the display screen body 1 needs to be opened or closed, the user can operate the dual-output motor 203 according to actual needs. The dual-output motor 203 has two output ends that can operate independently and can also be started separately according to needs. When one of the display screen bodies 1 needs to be moved, one output end of the dual-output motor 203 can be started to rotate the screw rod 204. The screw rod 204 is threadedly connected to the moving plate 205, and the moving plate 205 is bolted to the display screen body 1, so the screw rod 204 When rotating, the display screen body 1 will be driven to move, thereby achieving the effect of opening and closing. When the two display screen bodies 1 need to be moved together, the two output ends of the dual-output motor 203 can be used to drive the two screw rods 204 to rotate together, thereby achieving the effect of opening and closing the two display screen bodies 1 together. When the facing surface of the display screen body 1 needs to be rotated, the user directly rotates the bottom plate 201 to rotate the bottom plate 201 on the top of the turntable 202. When rotating the bottom plate 201, the sealing ring 11 can prevent foreign debris from entering between the bottom plate 201 and the turntable 202.

[0038] Specifically, Figure 5 As shown, the limiting component 3 includes an annular groove 301 and an annular column 302. The annular groove 301 is opened at the top of the turntable 202. The annular column 302 is rotatably connected to the inside of the annular groove 301. The top of the annular column 302 is welded to the bottom of the base plate 201. The cross-sectional shapes of the annular groove 301 and the annular column 302 are both "convex".

[0039] Specifically, Figure 5 As shown, a rotating ball 9 is rotatably connected to the bottom of the annular groove 301 , and the top of the rotating ball 9 is tightly fitted with the bottom of the annular column 302 .

[0040] When the base plate 201 rotates on the turntable 202, the base plate 201 drives the annular column 302 to rotate inside the annular groove 301. At the same time, the bottom of the annular column 302 contacts the rotating ball 9, thereby reducing the friction between the bottom of the annular column 302 and the bottom of the annular groove 301 and improving the rotation efficiency.

[0041] By adopting the above technical solution, the problem that the existing rotating opening and closing LED display screen controls the opening and closing of the display screen body 1 through the bidirectional screw rod 204 during use is solved, and the bidirectional screw rod 204 will inevitably cause the two display screen bodies 1 to open and close together, and the positions of the two display screen bodies 1 cannot be adjusted according to the actual needs of the user. At the same time, when using the display screen body 1, the audience needs to face the display screen body 1 directly to watch, which has high limitations.

[0042] Working principle: When in use, first screw the external bolts into the inside of the screw groove 12 to fix the device. When the display screen body 1 needs to be opened and closed, the user can operate the dual-output motor 203 according to actual needs. The dual-output motor 203 has two output ends that can operate independently and can also be started separately according to needs. When one of the display screen bodies 1 needs to be moved, one output end of the dual-output motor 203 can be started to rotate the screw rod 204. The screw rod 204 is threadedly connected to the moving plate 205, and the moving plate 205 is bolted to the display screen body 1. Therefore, when the screw rod 204 rotates, it will drive the display screen body 1 to move, thereby achieving the opening and closing effect. When the two display screen bodies 1 need to be moved together, the dual output motor 203 can be used. The two output ends of the output motor 203 drive the two screw rods 204 to rotate together, so as to achieve the effect of opening and closing the two display screen bodies 1 together. When the facing surface of the display screen body 1 needs to be rotated, the user directly rotates the bottom plate 201 to make the bottom plate 201 rotate on the top of the turntable 202. When the bottom plate 201 rotates on the turntable 202, the bottom plate 201 will drive the annular column 302 to rotate inside the annular groove 301. At the same time, the bottom of the annular column 302 will contact the rotating ball 9, thereby reducing the friction between the bottom of the annular column 302 and the bottom of the annular groove 301, and improving the rotation efficiency. When the bottom plate 201 is rotated, the sealing ring 11 can prevent foreign debris from entering between the bottom plate 201 and the turntable 202.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
