Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically an LED display screen and a cabinet arc-shaped locking device. Background Technology

[0002] An LED display screen is a flat-panel display device composed of many tiny light-emitting diodes. It can be controlled by electronic circuits to display various information such as text, graphics, images, animations, and videos. As an example, when the LED display screen is based on a curved screen and an arc-shaped edge, it can be combined with an arc-shaped locking device for the cabinet to fix the entire LED display screen, thereby ensuring the stability of the LED display screen and its stable use.

[0003] However, the existing LED display screen and cabinet arc lock device still have the following defects: Although the four corners of the current LED display screen are rounded, the roundness of the corners is too small and there are no fixing grooves, which will affect the connection effect with the cabinet arc lock device, causing assembly failure. As a result, the LED display screen cannot be stably adapted to the cabinet arc.

[0004] Meanwhile, the arc-shaped locking devices of the box are all locked one by one with bolts. As a result, the frequent locking or unlocking of the bolts is easily affected by external forces, which can cause the thread grooves to gradually expand and the thread teeth to be damaged. This will reduce the service life of the arc-shaped locking devices and make assembly and disassembly inconvenient. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an LED display screen and an arc-shaped lock device for the cabinet.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a display LED screen, the structure of which includes: a display body, a limiting frame, and an adapter frame, wherein the edge of the display body is covered by the limiting frame, and the inner wall of the adapter frame overlaps with the outer wall of the limiting frame;

[0007] A box-shaped arc-shaped lock device includes: a fitting wall, a frame, and an arc-shaped lock body. The fitting wall and the interior of the frame are an integrated structure, and the arc-shaped lock body passes through the arc-shaped corner area of ​​the frame and overlaps with it.

[0008] Furthermore, the adapter frame is provided with a through cavity, a solid body, overlapping walls, an arc-shaped groove, and an arc-shaped block. The through cavity is located at the center of the solid body. The solid body and the overlapping walls are an integrated structure. The arc-shaped groove passes through the overlapping walls and the corners of the solid body. The arc-shaped block is fixedly attached to the outer corner area of ​​the solid body and overlaps with the arc-shaped groove.

[0009] Furthermore, the arc-shaped groove is additionally provided with a reinforcing patch, an arc-shaped end, a restraining plate, and a through cavity. The reinforcing patch and the arc-shaped end are an integrated structure. The restraining plate is embedded in the central edge area of ​​the reinforcing patch and connected to the arc-shaped end on both sides. The through cavity passes through the central part of the restraining plate and the reinforcing patch.

[0010] Furthermore, the arc-shaped lock body is provided with an insertion module, a handheld block, an adsorption block, a vertical column, a protrusion, and a sliding rod. The insertion module is embedded in the surface of the handheld block, the upper end of the handheld block overlaps with the adsorption block, the vertical column is embedded in the adsorption block and fixedly connected to the handheld block, the protrusion is set at the upper end of the vertical column, and the sliding rod overlaps the center of the vertical column.

[0011] Furthermore, the solid body has a rust-proof shape and is square in shape, with all four corners being significantly rounded. Its size is adapted to the size of the arc groove and arc block, and the surface of the overlapping wall is finely polished.

[0012] Furthermore, the interlocking module is provided with a small threaded block, a solid ring, a rubber ring, and a notch. The upper end of the small threaded block is fixedly connected to the lower end of the solid ring. The rubber ring overlaps the inner area of ​​the solid ring and is located at the same center point. The notch is set at the center of the rubber ring and is an integral structure with it.

[0013] Furthermore, the interlocking module has three sets on the handheld block and is set in an arc shape. The handheld block is arc-shaped and perpendicular to the vertical column. The sliding rod at the center of the vertical column is solid. Beneficial effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model further improves upon the adaptation frame of the display body edge by using a large rounded corner as a basis, allowing the arc groove and arc block to adapt to the four corners of the solid body. At the same time, the newly added restraining plate of the arc groove can limit the two sides of the cavity, thus allowing the arc lock body to be vertically embedded, preventing tilting and jamming during the embedding assembly. Subsequently, the solid body can improve its fit with the arc lock body by cooperating with the arc groove and arc block, avoiding matching failure. Therefore, it can improve the connection stability between the LED display screen and the arc lock device of the cabinet.

[0016] 2. This utility model, through further improvements to the arc-shaped lock body, allows fingers to be inserted through the interlocking module on the hand block, thus achieving a convenient manual control effect. Subsequently, the vertical column on the hand block can be combined with the protrusion and slide bar to be embedded into the corner area of ​​the matching frame, thereby replacing the original multi-bolt locking process. This achieves a quick assembly effect and avoids damage to the threaded holes caused by frequent bolt disassembly and assembly, indirectly improving the stability of the arc-shaped lock device for LED displays and cabinets during frequent disassembly and assembly, preventing the inability to reassemble due to damage to the threaded holes after disassembly and assembly, and further extending the service life of the arc-shaped lock device.

[0025] like Figures 1-5 As shown, this utility model provides an LED display screen and a cabinet arc-shaped lock device.

[0026] Please see Figure 1 This utility model provides an LED display screen and a cabinet arc-shaped lock device, including: a display body a1, a limiting frame a2, and an adapter frame a3. The edge of the display body a1 is covered by the limiting frame a2. The inner wall of the adapter frame a3 overlaps with the outer wall of the limiting frame a2. There is also a fitting wall b1, a frame b2, and an arc-shaped lock body b3. The fitting wall b1 and the interior of the frame b2 are an integrated structure. The arc-shaped lock body b3 penetrates the arc-shaped corner area of ​​the frame b2 and overlaps with it.

[0027] Please see Figure 2 This utility model provides an LED display screen, comprising: an adapter frame a3 having a through cavity a31, a solid body a32, an overlapping wall a33, an arc-shaped groove a34, and an arc-shaped block a35; the through cavity a31 is located at the center of the solid body a32; the solid body a32 and the overlapping wall a33 are an integrated structure; the arc-shaped groove a34 penetrates the corners of the overlapping wall a33 and the solid body a32; the arc-shaped block a35 is fixedly attached to the outer corner area of ​​the solid body a32 and coincides with the arc-shaped groove a34; the solid body a32 has a rust-proof shape and is square, with all four corners being significantly rounded; its size is adapted to the size of the arc-shaped groove a34 and the arc-shaped block a35; and the surface of the overlapping wall a33 is finely polished.

[0028] The solid body a32 is made of stainless steel, which improves the external strength of the component. The large rounded corners effectively adapt to the curved component, avoiding assembly problems caused by insufficient curvature. The overlapping wall a33 is finely polished to improve the accuracy of overlapping with the component surface, preventing jamming and scratching during disassembly and assembly.

[0029] Please see Figure 3This utility model provides an LED display screen, including: the arc-shaped groove a34 is newly provided with a reinforcing patch 41, an arc-shaped end 42, a restraining plate 43, and a through cavity 44. The reinforcing patch 41 and the arc-shaped end 42 are an integrated structure. The restraining plate 43 is embedded in the central edge area of ​​the reinforcing patch 41 and is connected to the arc-shaped end 42 on both sides. The through cavity 44 passes through the central part of the restraining plate 43 and the reinforcing patch 41.

[0030] Please see Figure 4 This utility model provides a box-type arc-shaped lock device, comprising: the arc-shaped lock body b3 having an insert module b31, a handheld block b32, an adsorption block b33, a vertical column b34, a protrusion b35, and a sliding rod b36; the insert module b31 is embedded in the surface of the handheld block b32, the upper end of the handheld block b32 overlaps with the adsorption block b33; the vertical column b34 is embedded in the adsorption block b33 and fixedly connected to the handheld block b32; the protrusion b35 is disposed at the upper end of the vertical column b34; and the sliding rod b36 overlaps the center of the vertical column b34; the insert module b31 has three sets on the handheld block b32 and is set in an arc shape; the handheld block b32 is arc-shaped and perpendicular to the vertical column b34; and the sliding rod b36 at the center of the vertical column b34 is solid.

[0031] The insertion module b31 allows fingertips to be inserted in three sets, facilitating manual control. The handheld block b32, with its arc shape, matches the shape of the component. The vertical column b34, along with the central sliding rod b36, can be inserted into the component in a straight line to achieve a fixed connection. This replaces the original assembly process with multiple bolts, improving assembly convenience and extending the service life of components. It also prevents deformation caused by external pressure on holes created by frequent locking or unlocking.

[0032] Please see Figure 5 This utility model provides a box-shaped arc lock device, including: the insertion module b31 is provided with a small threaded block 11, a solid ring 12, a rubber ring 13, and a notch 14. The upper end of the small threaded block 11 is fixedly connected to the lower end of the solid ring 12. The rubber ring 13 overlaps the inner area of ​​the solid ring 12 and is located at the same center point. The notch 14 is set at the center of the rubber ring 13 and is an integral structure with it.

[0033] The working principle of this utility model is explained below:

[0034] First: The edge of the LED display body a1 will be restrained by the limiting frame a2, so that the display body a1 will be set in a vertical position. Then, the adapter frame a3 outside the limiting frame a2 can be made to overlap with the frame b2 by significantly rounding the four corners. This allows the fitting wall b1 of the frame b2 to fit with the adapter frame a3, preventing tilting and scratching. Furthermore, the frame b2 can use the significantly rounded corners to allow the four sets of arc-shaped lock bodies b3 to be inserted, thereby completing the connection with the LED display. At the same time, it can improve the shape matching between the two and replace the original one-to-one connection effect of multiple bolts. It avoids the damage to the thread groove caused by frequent bolt disassembly, which would prevent the arc-shaped lock bodies b3 and the frame b2 from being reused. This indirectly improves the service life of all components and improves the convenience of later maintenance and disassembly.

[0035] Second: The solid body a32 of the adapter frame a3 can be embedded into the display body a1 through the internal through cavity a31. Then, the overlapping wall a33 of the solid body a32 can fit with the edge of the display body a1. For this purpose, the arc groove a34 at the corner of the overlapping wall a33 can be connected with the corner of the limiting frame a2. At the same time, the arc block a35 at the outer corner of the solid body a32 can be fixed to the outer area of ​​the arc groove a34, so that the arc lock body b3 can directly penetrate the arc block a35 through its own arc shape, and then enter the arc groove a34 to complete the connection with the limiting frame a2 and the display body a1. Therefore, the connection stability between the components can be improved.

[0036] Third: The newly added reinforcing patch 41 in the arc groove a34 area can improve its strength through the high hardness of carbon steel. Then, the reinforcing patch 41 can be fixed to the inner corner area of ​​the solid body a32 through the shape of the arc end 42, avoiding mismatch caused by inconsistent shapes. Then, the restraining plates 43 on both sides of the center of the reinforcing patch 41 can cover the edge of the cavity 44, so that after the arc lock body b3 is inserted, it can be vertically inserted into the corner area of ​​the limiting frame a2 and the display body a1 through the cavity 44 to achieve a precise connection.

[0037] Fourth: The handheld block b32 of the arc-shaped lock body b3 can achieve the effect of easy manual control through the insertion module b31. Then, the suction block b33 at the upper end of the handheld block b32 can be combined with the vertical column b34, the protrusion b35, and the slide bar b36 to be embedded into the arc-shaped groove a34 area. During the process, the slide bar b36 can improve the positional accuracy of the vertical column b34 when it is embedded through the vertical effect. Finally, when the protrusion b35 enters the corner area of ​​the display body a1, it can overlap with it. At the same time, the suction block b33 of the handheld block b32 will be attached to the surface of the arc-shaped block a35, further improving the connection between the components and replacing the original multiple bolt connections through the insertion fixation, avoiding the unusable components due to damage to the threaded groove.

[0038] Fifth: The lower end of the solid ring 12 of the interlocking module b31 can be fixedly connected to the handheld block b32 through a small threaded block 11, so that its detachable effect can improve its practicality and complete the connection with other components, so as to facilitate the manual control of the rotation of other components. Then, the rubber ring 13 inside the solid ring 12 can be inserted into the notch 14, so that when the finger is covered by the rubber ring 13, there will be no discomfort caused by contact with the metal surface during the twisting process, thus ensuring the safety of the manually controlled component.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
