Description

Technical Field

[0001] This utility model relates to the field of display screen support technology, and in particular to a support frame for LED displays. Background Technology

[0002] An LED display screen is a display screen composed of light-emitting diodes (LEDs). It is an electronic display device that displays text, images, videos, and other information by controlling the brightness of the LEDs. LED displays have advantages such as high brightness, energy saving, environmental friendliness, long lifespan, fast response speed, wide viewing angle, and stable display effect. They are widely used in advertising media, sports venues, stage rental, traffic guidance, information dissemination, and many other fields. Their working principle involves controlling the brightness combination of the red, green, and blue colors of each LED pixel to present different colors and grayscale levels, thereby displaying rich and varied visual content.

[0003] The current traditional LED display support frame design has certain limitations. When installing LED displays, this type of support frame usually adopts a fixed angle installation method, which makes it impossible for users to flexibly adjust the viewing angle of the display according to actual needs. Therefore, if problems such as poor viewing angle or light reflection are encountered during use, users cannot improve the viewing experience by adjusting the angle of the display, resulting in inconvenience and reduced applicability. Utility Model Content

[0004] One objective of this invention is to provide a support frame for LED displays. This invention addresses the problem that the support frame mentioned in the background typically uses a fixed-angle installation method when installing LED displays. This prevents users from flexibly adjusting the viewing angle of the display according to actual needs. Therefore, during use, if problems such as poor viewing angle or light reflection are encountered, users find it difficult to improve the viewing experience by adjusting the display angle, resulting in inconvenience and reduced applicability.

[0005] A support frame for an LED display screen according to an embodiment of the present invention includes a locking mechanism for locking the tilt angle of the display screen structure, which is installed between the display screen structure and the movable base. The locking mechanism includes a fixed end, a sliding end, and a stop bar. The fixed end is movably mounted on the movable base, and the sliding end is movably connected inside the fixed end. The surface of the fixed end has a groove for the stop bar to slide inside, and the surface of the groove has a toothed groove for locking the position of the stop bar. A hook is fixedly connected to the surface of the sliding end. The side surface of the sliding end is movably connected to the stop bar through a rotating wheel and a connecting rod. The side surface of the rotating wheel has a first groove and a second groove respectively. One side of the inner wall of the groove has a first ramp for the stop bar to reset, and the other side of the inner wall of the groove has a second ramp for the stop bar to spring up and lock the hook in the second groove.

[0006] Preferably, the first ramp is disposed on the upper surface of the lower end of the inner wall of the chute, and the second ramp is disposed on the lower surface of the lower part of the inner wall of the chute.

[0007] Preferably, the fixed end is rotatably connected to the upper surface of the movable base via a first fixed seat.

[0008] Preferably, the sliding end is rotatably connected to the upper part of the rear surface of the display screen structure via a second fixed seat.

[0009] Preferably, when the stop bar slides within the toothed groove, the hook is located within the first groove; when the stop bar passes through the second ramp, the hook is engaged within the second groove; and when the stop bar passes through the first ramp, the hook moves from the second groove to the first groove.

[0010] Preferably, the lower part of the stop lever is provided with a reset structure to ensure that the stop lever is in the tooth groove. The reset structure includes a reset spring, a limiting groove and a limiting block. The limiting groove is opened on the surface of the fixed end, and the limiting block is slidably connected inside the limiting groove.

[0011] Preferably, a return spring is provided between the surface of the limiting block and the side surface of the stop bar for realizing the downward reset of the stop bar.

[0012] Preferably, the display screen structure is rotatably connected to the upper surface of the movable base via a pivot, and the tilting angle of the display screen structure is achieved by the sliding end of the locking mechanism sliding inside the fixed end.

[0013] The beneficial effects of the utility model are:

[0014] This invention utilizes a locking mechanism to manually adjust the display screen structure to a near-vertical state when adjusting the display angle. During this process, the sliding end slides inside the fixed end. When the stop lever slides to the recessed area of ​​the toothed groove, the hook is positioned inside the first groove. After the angle adjustment is complete, the display screen structure is released. Due to gravity, the display screen structure applies pressure to the sliding end, which transmits this pressure through the connecting rod to the stop lever. The stop lever engages inside the toothed groove, thus locking the tilt angle of the display screen structure. When it is necessary to rotate the display screen structure backward to adjust the angle, the display screen is rotated forward to its limit, and the stop lever slides upward to its limit via the second ramp. The stop lever drives the rotating wheel to rotate clockwise via the connecting rod until the hook is engaged inside the second groove, locking the rotation angle of the rotating wheel, connecting rod, and stop lever. At this time, when the display structure rotates backward, the stop lever is above the tooth groove. Until the display structure rotates backward to its limit, the stop lever is pressed downward by the pressure of the first ramp, causing the hook to slide out from inside the second groove and into the first groove. Rotating the display structure forward again repeats the above process of the stop lever being engaged inside the tooth groove, locking the display angle of the display structure. This achieves stable angle adjustment and automatic locking of the display structure, simplifies the adjustment process, improves ease of use, and enhances the stability of the display at different angles.

[0015] This invention, through its reset structure and reset spring, ensures that the stop lever is in the recessed part of the tooth groove under normal conditions, thus avoiding the problem of locking failure and improving the reliability and ease of operation of the locking mechanism.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] refer to Figure 1-4A support frame for an LED display screen includes a locking mechanism 4 installed between a display screen structure 6 and a movable base 1 for locking the tilt angle of the display screen structure 6. The locking mechanism 4 includes a fixed end 401, a sliding end 402, and a stop bar 409. The fixed end 401 is movably mounted on the movable base 1, and the sliding end 402 is movably connected inside the fixed end 401. The surface of the fixed end 401 has a groove 403 for the stop bar 409 to slide inside. The surface of the groove 403 has a toothed groove 404 for locking the position of the stop bar 409. When the stop bar 409 slides upward in the toothed groove 404, it can slide easily through the inclined surface on the right side of the toothed groove 404. When the stop bar 409 needs to slide downward in the toothed groove 404, the stop bar 409... The right-angled surface on the left side of the toothed groove 404 blocks the rotation angle of the display screen structure 6, thereby locking the rotation angle. A hook 412 is fixedly connected to the surface of the sliding end 402. A stop bar 409 is movably connected to the side surface of the sliding end 402 through the rotating wheel 407 and the connecting rod 408. The side surface of the rotating wheel 407 is respectively provided with a first groove 410 and a second groove 411. A first ramp 405 for resetting the stop bar 409 is provided on one side of the inner wall of the slide groove 403. A second ramp 406 for the stop bar 409 to spring up and lock the hook 412 in the second groove 411 is provided on the other side of the inner wall of the slide groove 403. When adjusting the display angle of the display screen structure 6, the display screen structure 6 is manually adjusted to a near-vertical state. During this process, the sliding end 402 Sliding inside the fixed end 401, when the stop lever 409 slides to the recess of the toothed groove 404, the hook 412 is inside the first groove 410. After the angle adjustment is completed, the display screen structure 6 is released directly. Due to gravity, the display screen structure 6 will apply pressure to the sliding end 402 behind it. The sliding end 402 transmits the pressure to the stop lever 409 through the connecting rod 408. The stop lever 409 is locked inside the toothed groove 404, thus locking the tilt angle of the display screen structure 6. When it is necessary to rotate the display screen structure 6 to the rear to adjust the angle, the display screen is rotated forward to the limit. The stop lever 409 is slid upward to the limit through the second ramp 406. At this time, the stop lever 409 drives the rotating wheel 407 to rotate clockwise through the connecting rod 408 until the hook 412 is locked in the second groove 410. Inside the groove 411, the rotation angle of the rotating wheel 407, connecting rod 408, and stop lever 409 is locked. When the display screen structure 6 rotates backward, the stop lever 409 is above the tooth groove 404. Until the display screen structure 6 rotates backward to its limit, the stop lever 409 is pressed downward by the pressure of the first ramp 405, causing the hook 412 to slide out from inside the second groove 411 and into the first groove 410. Then, rotating the display screen structure 6 forward repeats the process of the stop lever 409 being locked inside the tooth groove 404, thus locking the display angle of the display screen structure 6. This achieves stable angle adjustment and automatic locking of the display screen structure 6, simplifies the adjustment process, and improves ease of use and stability of the display screen at different angles.

[0023] Example 1: The first ramp 405 is set on the upper surface of the lower end of the inner wall of the slide groove 403, and the second ramp 406 is set on the lower surface of the lower part of the inner wall of the slide groove 403. The fixed end 401 is rotatably connected to the upper surface of the movable base 1 through the first fixed seat 2, and the sliding end 402 is rotatably connected to the upper part of the rear side surface of the display screen structure 6 through the second fixed seat 3. When the stop bar 409 slides in the tooth groove 404, the hook 412 is in the first groove 410. When the stop bar 409 passes through the second ramp 406, the hook 412 is stuck in the second groove 411. When the stop bar 409 passes through the first ramp 405, the hook 412 moves from the second groove 411 to the first groove 410.

[0024] Example 2: A reset structure 5 is provided at the lower part of the stop lever 409 to ensure that the stop lever 409 is in the tooth groove 404. The reset structure 5 includes a reset spring 503, a limiting groove 501 and a limiting block 502. The limiting groove 501 is opened on the surface of the fixed end 401. The limiting block 502 is slidably connected to the inside of the limiting groove 501. A reset spring 503 is provided between the surface of the limiting block 502 and the side surface of the stop lever 409 to realize the downward reset of the stop lever 409. The reset spring 503 of the reset structure 5 makes the stop lever 409 in the recess of the tooth groove 404 under normal conditions, avoiding the problem of locking failure, thereby improving the reliability and ease of operation of the locking mechanism. The display screen structure 6 is rotatably connected to the upper surface of the movable base 1 through a rotating shaft. The tilting angle of the display screen structure 6 is realized by the sliding end 402 of the locking mechanism 4 sliding inside the fixed end 401.

[0025] In use, when the user needs to adjust the display structure 6 to a near-vertical state, the sliding end 402 of the locking mechanism 4 slides inside the fixed end 401, and the stop lever 409 slides within the toothed groove 404 in the slide groove 403. The hook 412 is located within the first groove 410. When the display structure 6 reaches the desired angle, the user releases the display structure 6. Due to gravity, the display structure 6 applies pressure to the sliding end 402. The sliding end 402 transmits the pressure to the stop lever 409 through the connecting rod 408, causing the stop lever 409 to lock into the right-angled surface on the left side of the toothed groove 404, preventing the stop lever 409 from sliding further downward from its current position within the toothed groove 404. This locks the tilt angle of the display structure 6. If the user needs to adjust the angle of the display structure 6 to the rear, the user needs to rotate the display structure 6 forward to its limit. At this time, the second ramp 406 causes the stop lever 409 to slide upward to its limit. The connecting rod 408 drives the rotating wheel 407 to rotate clockwise, causing the hook 412 to engage in the second groove 411, locking the rotation angle of the rotating wheel 407, connecting rod 408, and stop lever 409. Subsequently, the user can rotate the display structure 6 to the rear, with the stop lever 409 positioned above the toothed groove 404, until the display structure 6 rotates to its rearward limit. At this point, the stop lever 409 is pressed downward by the pressure of the first ramp 405, causing the hook 412 to slide out of the second groove 411 and return to the first groove 410. Finally, the user rotates the display structure 6 forward again, and the stop lever 409 will re-engage in the toothed groove 404, completing the angle locking. This achieves stable angle adjustment and automatic locking of the display structure 6, simplifying the adjustment process and improving ease of use and stability. The presence of the reset structure 5 ensures that the stop lever 409 is always within the toothed groove 404, avoiding locking failure and further improving the reliability of the locking mechanism.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
