Description

Technical Field

[0001] This utility model relates to the field of display module technology, and in particular to LED display screen cabinet frame. Background Technology

[0002] LED displays are typically composed of multiple LED cabinets spliced ​​together to form a large display area. In existing technology, the splicing method of LED cabinets is generally as follows: adjacent top and bottom, left and right cabinets are fixed together with screws. After the connection is completed, the edge planes of the adjacent cabinet frames are pulled tight and pressed together to form an overall display frame.

[0003] However, the above structure has certain limitations. The main limitation is that the adjacent cabinet frames are completely flattened and fixed after connection, making it impossible to fine-tune the splicing gap. This can easily lead to the following problems: First, misalignment may occur during the assembly process, resulting in bright or black splicing lines on the entire screen, affecting the display effect. Second, when there is no reasonable gap between the cabinet frames, the LED light board may be squeezed during installation, resulting in dead or broken lights, reducing the reliability and lifespan of the product.

[0004] Therefore, there is an urgent need for an LED display cabinet frame to solve the above problems. Utility Model Content

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0047] This embodiment provides an LED display screen cabinet frame, such as Figures 1-2As shown, the LED display cabinet frame includes multiple frames 100, an X-axis adjustment mechanism 200, a Y-axis adjustment mechanism 300, and a Z-axis adjustment mechanism 400. Each frame 100 includes four side borders connected sequentially to form a rectangle. The multiple frames 100 are arranged in a rectangle to splice together to form the LED display cabinet frame. The X-axis adjustment mechanism 200 is used to fasten two adjacent side borders in the X-axis direction and can adjust the gap between the two adjacent side borders in the X-axis direction. The Y-axis adjustment mechanism 300 is used to fasten two adjacent side borders in the Y-axis direction and can adjust the gap between the two adjacent side borders in the Y-axis direction. A Z-axis adjustment mechanism 400 is provided at the splicing point of two adjacent side borders along the X-axis direction and / or at the splicing point of two adjacent side borders along the Y-axis direction. The Z-axis adjustment mechanism 400 is used to adjust the relative position of the two adjacent side borders in the Z-axis direction.

[0048] Through the above design, the splicing gaps between adjacent frames 100 can still be finely adjusted in three dimensions after assembly. This effectively avoids the squeezing of the LED light board caused by the forced flattening and bonding of adjacent frames, reducing the risk of dead LEDs and broken LED beads. This also avoids splicing bright or black lines caused by assembly errors, improving the overall display effect. Furthermore, the independent adjustment capabilities in the X, Y, and Z axes give the cabinet frame greater flexibility and adaptability, effectively improving the installation efficiency of the LED display cabinet frame and enhancing product reliability and lifespan. In addition, the modular splicing method of the LED display cabinet frame facilitates the installation and maintenance of large-area displays and allows for quick splicing calibration during later maintenance or replacement of individual cabinets, further reducing maintenance costs.

[0049] For example, such as Figures 1-2 As shown, the X-axis is defined as the left-right direction of the LED display cabinet frame, with the left direction being X- and the right direction being X+. The Y-axis is defined as the up-down direction, with the up direction being Y+ and the down direction being Y-. The Z-axis is defined as the front-back direction, with the front direction being Z+ and the back direction being Z-. The detailed structure and adjustment principle of the X-axis adjustment mechanism 200, the Y-axis adjustment mechanism 300, and the Z-axis adjustment mechanism 400 are explained.

[0050] Optionally, each frame 100 has four borders, including a first border 110 and a second border 120 that are opposite each other along the X-axis direction (i.e., the left-right direction). In two adjacent frames 100 along the X-axis direction, such as... Figure 3As shown, the first frame 110 of the right frame 100 is spliced ​​with the second frame 120 of the left frame 100. The first frame 110 is provided with a first light hole 111 and a first adjustment hole 112 along the X-axis direction. The second frame 120 is provided with a first threaded hole 121 corresponding to the first light hole 111. The X-axis adjustment mechanism 200 includes a first fastener 210 and a first adjustment member 220. The first fastener 210 passes through the first light hole 111 and is threadedly engaged with the first threaded hole 121 so that the first frame 110 and the second frame 120 adjacent in the X-axis direction are fastened together. The first adjustment member 220 is threadedly engaged with the first adjustment hole 112, and the first adjustment member 220 can extend out of the first adjustment hole 112 and abut against the second frame 120 corresponding to it. When adjusting the gap between adjacent first frame 110 and second frame 120, first loosen the first fastener 210, then tighten the first adjusting member 220 so that its end abuts against the left first frame 110, pushing it to move in the X- direction. After adjustment, tighten the first fastener 210 to increase the gap. If it is necessary to move the left first frame 110 in the X+ direction, loosen the first fastener 210, then loosen the first adjusting member 220. When tightening the first fastener 210, the tightening force can pull the left first frame 110 to move in the X+ direction, thus decreasing the gap.

[0051] Optionally, in this embodiment, the first fastener 210 can be a fastening screw with an M6 specification, and the first adjusting member 220 can be a fastening screw with an M3 specification. In this embodiment, the specifications of the first fastener 210 and the first adjusting member 220 are not limited, and can be selected according to actual needs.

[0052] Optionally, each frame 100 has four borders, including a third border 130 and a fourth border 140 that are opposite each other along the Y-axis (i.e., the vertical direction). In two adjacent frames 100 along the Y-axis, such as... Figure 4As shown, the third frame 130 of the upper frame 100 abuts against the fourth frame 140 of the lower frame 100; the third frame 130 is provided with a second light hole 131 and a second adjustment hole 132 along the Y-axis direction, and the fourth frame 140 is provided with a second threaded hole 141 corresponding to the second light hole 131. The Y-axis adjustment mechanism 300 includes a second fastener 310 and a second adjustment member 320. The second fastener 310 passes through the second light hole 131 and is threadedly engaged with the second threaded hole 141 so that the third frame 130 and the fourth frame 140 adjacent in the Y-axis direction are threadedly connected. The second adjustment member 320 is threadedly engaged with the second adjustment hole 132, and the second adjustment member 320 can extend out of the second adjustment hole 132 and abut against the corresponding fourth frame 140. When adjusting the gap between adjacent third frame 130 and fourth frame 140, first loosen the second fastener 310, then tighten the second adjusting member 320 so that its end abuts against the lower fourth frame 140, pushing it to move in the Y- direction. After adjustment, tighten the second fastener 310 to increase the gap. If it is necessary to move the lower fourth frame 140 in the Y+ direction, loosen the second fastener 310, then loosen the second adjusting member 320. When tightening the second fastener 310, the tightening force can pull the lower fourth frame 140 to move in the Y+ direction, thus decreasing the gap.

[0053] Optionally, in this embodiment, the second fastener 310 can be a fastening screw with an M6 specification, and the second adjusting member 320 can be a fastening screw with an M3 specification. In this embodiment, the specifications of the second fastener 310 and the second adjusting member 320 are not limited, and can be selected according to actual needs.

[0054] Optionally, such as Figure 5 , Figure 6 and Figure 7As shown, one of the two adjacent frame sides has a third threaded hole 101 along the Z-axis direction, and the other of the two adjacent frame sides has a fourth threaded hole 102 along the Z-axis direction. The Z-axis adjustment mechanism 400 includes a connecting piece 410 and an adjustment assembly 420. The connecting piece 410 has a third light hole 411, a third adjustment hole 412, a fourth light hole 413, and a fourth adjustment hole 414 along the Z-axis direction. The third light hole 411 corresponds to the third threaded hole 101, and the fourth light hole 413 corresponds to the fourth threaded hole 102. The adjustment assembly 420 includes a third fastener 421, a third adjustment member 422, and a fourth fastener 423. The third fastener 421 passes through the third light hole 411 and is threaded into the third threaded hole 101. The third adjusting member 422 is threaded into the third adjusting hole 412 and can extend out of the third adjusting hole 412 to abut against one of the two adjacent frame pieces. The fourth fastener 423 passes through the fourth light hole 413 and is threaded into the fourth threaded hole 102. The fourth adjusting member 424 is threaded into the fourth adjusting hole 414 and can extend out of the fourth adjusting hole 414 to abut against the other of the two adjacent frame pieces. Through the above design, the two adjacent frame pieces can be adjusted in the front-back direction, ensuring the flatness of the display screen mounting surface. Specifically, the two adjacent frame pieces can be the first frame piece 110 and the second frame piece 120 adjacent in the left-right direction, or the third frame piece 130 and the fourth frame piece 140 adjacent in the up-down direction, thereby realizing independent adjustment of the frame 100 at different splicing positions in the Z-axis direction.

[0055] For example, the adjustment process of the Z-axis adjustment mechanism 400 will be described using the first frame 110 and the second frame 120 that are adjacent in the left and right directions as an example.

[0056] During the adjustment process, such as Figure 7 As shown, if the position of the first frame 110 needs to be adjusted, the fourth locking member and the fourth adjusting member 424 remain stationary. Loosen the third fastener 421, and tighten the third adjusting member 422. The end of the third adjusting member 422 abuts against the left first frame 110 and moves in the Z+ direction. Then, tighten the third fastener 421 to complete the adjustment. If the left first frame 110 needs to move in the Z- direction, loosen the third fastener 421, then loosen the third adjusting member 422, and then tighten the third fastener 421. The tightening force will pull the left first frame 110 to move in the Z- direction. Adjusting the position of the right second frame 120 in the Z-axis direction is similar to the above process, except that the third fastener 421 and the third adjusting member 422 remain stationary, and the fourth fastener 423 and the fourth adjusting member 424 are adjusted. The adjustment process of the second frame 120 in the Z-axis direction will not be described in detail.

[0057] Optionally, the third fastener 421 and the fourth fastener 423 can be M4 screws, and the third adjusting member 422 and the fourth adjusting member 424 can be M3 screws. The third adjusting hole 412 and the fourth adjusting hole 414 are both threaded holes, so that the third adjusting hole 412 is threadedly engaged with the third adjusting member 422, and the fourth adjusting member 424 is threadedly engaged with the fourth adjusting hole 414. In other embodiments, the specifications of the third fastener 421, the fourth fastener 423, the third adjusting member 422, and the fourth adjusting member 424 are not limited and can be selected according to specific installation requirements or structural dimensions. This ensures the applicability and flexibility of the Z-axis adjustment mechanism 400 in different application scenarios, while still achieving a stable connection and precise adjustment, improving splicing flatness and display effect.

[0058] In this embodiment, the LED display cabinet frame includes four frames 100. A Z-axis adjustment structure is provided at the center of the LED display cabinet formed by the four frames 100. The Z-axis adjustment mechanism 400 is connected to the four frames 100 at the same time, so the Z-axis direction of the four frames 100 at this position can be adjusted uniformly, thereby ensuring the flatness and splicing accuracy of the central area of ​​the display screen, and improving the overall display effect and installation quality.

[0059] Optionally, in two adjacent frames facing each other along the X-axis, the left frame is provided with a first groove 113, and the first groove 113 is located on the side of the corresponding frame 100 away from the display screen. The right frame is provided with a second groove 122, and the second groove 122 is located on the side of the corresponding frame 100 away from the display screen. The first groove 113 and the first groove 122 are spliced ​​together to form a first limiting groove. The first limiting groove is used to accommodate the connecting piece 410, so that the connecting piece 410 can be stably limited and avoids displacement or loosening during installation or adjustment.

[0060] Optionally, one of two adjacent frame edges along the Y-axis has a third groove and the other has a fourth groove. The third groove can be joined with the fourth groove to form a second limiting groove, which is used to accommodate the connecting piece 410. This ensures that the connecting piece 410 can be reliably positioned and limited, preventing displacement or shaking during installation or adjustment.

[0061] In this embodiment, by setting a first groove 113 and a second groove 122 on two adjacent frames along the X-axis, forming a first limiting groove after splicing, and by setting a third groove and a fourth groove on two adjacent frames along the Y-axis, forming a second limiting groove after splicing, the connecting piece 410 can be reliably limited and positioned at splicing points in different directions. This structure effectively prevents the connecting piece 410 from shifting, tilting, or loosening during installation or adjustment, further improving the accuracy and flatness of the entire screen splicing, enhancing the display effect, and extending the product's lifespan.

[0062] Optionally, the third light hole 411 and the fourth light hole 413 are both countersunk holes, so that the heads of the third fastener 421 and the fourth fastener 423 can be flush with the surface of the connecting piece 410. This not only avoids the fasteners from protruding and affecting the splicing accuracy of adjacent frames 100, but also improves the overall structural stability and aesthetics, and helps to ensure the flatness of the splicing surface of the display screen.

[0063] Optionally, the connecting piece 410 is a metal sheet stamping part. The connecting piece 410 has high structural strength, good processing accuracy and low cost, and is easy to mass-produce, thereby improving the reliability and economy of the overall structure.

[0064] Optionally, the connecting piece 410 is roughly rectangular in shape, so that the force at the edge splicing point is more uniform, which is not only convenient for processing and installation, but also improves the stability of limiting and adjusting, thereby ensuring the reliability and flatness of the overall splicing of the display screen.

[0065] Optionally, the connecting piece 410 has a weight reduction hole in the middle, which can reduce the overall weight of the connecting piece 410 without affecting its strength and stability, reduce the load on the whole machine, improve the convenience of installation and operation, and save material costs.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
