Description

Technical Field

[0001] This utility model relates to the field of LED displays, specifically to a splicing frame for LED displays. Background Technology

[0002] LED displays are devices that control semiconductor light-emitting diodes. Multiple LED beads form pixel units, which in turn constitute a display screen. Due to their significant characteristics such as high brightness, vivid colors, long lifespan, low energy consumption, and fast response speed, they are widely used in many fields such as advertising, information dissemination, stage performances, and traffic guidance. Whether it is a giant advertising screen on a bustling city street or a colorful backdrop on a stage, LED displays attract people's attention with their excellent display effects.

[0003] Currently, in practical applications, in order to meet different sizes and display requirements, it is often necessary to combine and splice multiple LED displays. The existing splicing method mainly involves installing a fixing frame on the outer wall of the LED display and then using bolts to connect adjacent fixing frames.

[0004] However, this method of connecting multiple LED displays by using bolts to fix the frame has obvious drawbacks. Due to the presence of the fixing frame and bolts, a certain width of splicing gap will be generated between adjacent LED displays. This will cause the images between LED displays to be inconsistent when displaying continuous images, resulting in image breaks, which seriously affects the visual effect and the accuracy of information transmission. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a splicing frame for LED displays to solve the technical problem that the combined LED display screen is prone to breakage when multiple LED displays are spliced ​​together by fixing a frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a splicing frame for an LED display screen, including a display screen, a buffer assembly installed on the inner wall of the display screen, an installation plate fixed to the end of the buffer assembly, a first connecting block and a second connecting block respectively installed at both ends of the installation plate, a second locking block provided inside the first connecting block, two sets of second springs installed at one end of the second locking block, a slot opened inside the second connecting block, a first locking block installed inside the slot, and two sets of first springs installed on the top of the first locking block.

[0007] By adopting the above technical solution, the problem of easy breakage of the combined LED display screen caused by using a fixing frame to combine multiple LED display screens is solved. When the edges of the two display screens are aligned and fixed, the second spring pushes the second locking block into the slot inside the second connecting block. The second locking block presses the first locking block upward, causing the first locking block to compress and contract the first spring. When the second locking block moves to the end of the inner wall of the slot, the first spring, which is in a compressed state, pushes the first locking block downward, so that the first locking block latches and fixes the second locking block. This latching splicing method reduces the gap between the two display screens, thereby making the combined display screen display a more complete image.

[0008] The present invention is further configured such that the buffer assembly includes multiple sets of fixing blocks, one end of each fixing block is connected to a spring damper, and the end of the damping rod in the spring damper is located inside the mounting plate.

[0009] Preferably, when the display screen is squeezed by an external object, the fixed block on the inner wall of the display screen transmits the pressure to the spring damper, which buffers the display screen and reduces the impact force of the external object on the display screen.

[0010] The present invention is further configured such that a limiting post is installed on the top of the first card block, and the top of the limiting post is located in the second connecting block.

[0011] Preferably, when the second block presses against the first block, the second connecting block limits the movement of the first block through the limiting post, so that the first block moves up and down in the vertical direction.

[0012] The present invention is further configured such that the second card block has a card slot inside, a fixing component is installed inside the card slot, the fixing component includes a fixing strip, and a third spring is connected to the bottom of the fixing strip.

[0013] Preferably, the third spring pushes the fixing bar into the slot, and the fixing bar limits and fixes the second block in the first connecting block, thereby enabling the display screen to move perpendicular to the fixed wall.

[0014] The present invention is further configured such that the inner wall of the slot is inclined, and the elastic coefficient of the third spring is less than that of the second spring.

[0015] Preferably, after the operator releases the display screen, the spring damper of the compressed spring drives the squeezing column to move out of the slot, and the second spring in the compressed state pushes the second locking block. Since the elastic coefficient of the second spring is greater than that of the third spring located at the bottom of the fixing bar, the moving speed of the second spring pushing the second locking block is greater than the speed of the third spring pushing the fixing bar. This causes the slot to be displaced to the side above the fixing bar before the fixing bar rises to the bottom of the inner wall of the slot.

[0016] The present invention is further configured such that two sets of fixing plates are fixed to the inner wall of the display screen, and an extrusion column is connected to the top of the fixing strip, and the top of the extrusion column is connected to the fixing plate.

[0017] Preferably, when a person presses the display screen, the display screen moves the squeezing column downward through two sets of fixing plates on its inner wall, so that the squeezing column squeezes the fixing strip to the bottom of the second block.

[0018] The present invention is further configured such that the inner wall of the fixing plate is provided with a sliding groove, and the outer wall of the top end of the extrusion column is fixed with a connecting column.

[0019] Preferably, if the display screen is tilted downwards and pressed, the connecting column at the top of the extrusion column slides in the sliding groove on the inner wall of the fixed plate, so that the extrusion column can still move vertically downwards.

[0020] The present invention is further configured such that the total length of the mounting plate, the first connecting block and the second connecting block is equal to the width of the display screen.

[0021] Preferably, when the edges of the two sets of displays are aligned and in contact, the first connecting block and the second connecting block can make contact, thereby facilitating the subsequent locking of the second clip into the second connecting block.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem of image breakage in LED displays caused by using a fixed frame to combine multiple LED displays. By setting up a display screen, mounting plate, first locking block, second locking block, first connecting block, and second connecting block, this utility model solves the problem of image breakage in LED displays when using a fixed frame to combine multiple LED displays. When the edges of two displays are aligned and fixed, the second spring pushes the second locking block into the slot inside the second connecting block. The second locking block presses the first locking block upward, causing the first locking block to compress the first spring. When the second locking block moves to the end of the inner wall of the slot, the first spring, which is under compression, pushes the first locking block downward, causing the first locking block to lock and fix the second locking block. This locking splicing method reduces the gap between the two displays, thus making the image displayed on the combined display screen more complete.

[0024] 2. This utility model is designed with a fixing strip, a third spring, a slot, a pressing column, a connecting column, and a fixing plate. The third spring pushes the fixing strip into the slot, and the fixing strip limits and fixes the second block in the first connecting block, thereby allowing the display screen to move perpendicular to the fixed wall. When two sets of display screens are combined and spliced, the operator can press the display screen to make the pressing column press the fixing strip to the bottom of the second block. After the operator releases the display screen, the second spring, which is in a compressed state, pushes the second block to the slot in the second connecting block. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Please see Figure 1 — Figure 7 The system includes a display screen 1, with a buffer assembly installed on the inner wall of the display screen 1. A mounting plate 2 is fixed to the end of the buffer assembly. A first connecting block 3 and a second connecting block 4 are respectively installed at both ends of the mounting plate 2. A second locking block 5 is provided inside the first connecting block 3, and two sets of second springs 501 are installed at one end of the second locking block 5. A slot 401 is opened inside the second connecting block 4, and a first locking block 402 is installed inside the slot 401. Two sets of first springs 403 are installed on the top of the first locking block 402. This design solves the problem of image breakage easily in combined LED displays caused by using a fixing frame to combine multiple LED displays. In response to the situation, when the edges of the two sets of display screens 1 are aligned and fixed, the second spring 501 pushes the second locking block 5 into the slot 401 inside the second connecting block 4. The second locking block 5 presses the first locking block 402 upward, causing the first locking block 402 to compress and contract the first spring 403. When the second locking block 5 moves to the end of the inner wall of the slot 401, the first spring 403, which is in a compressed state, pushes the first locking block 402 downward, causing the first locking block 402 to lock and fix the second locking block 5. This locking splicing method reduces the gap between the two sets of display screens 1, thereby making the combined display screen 1 display a more complete image.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The buffer assembly includes multiple sets of fixing blocks 101. One end of the fixing block 101 is connected to a spring damper 102, and the end of the damping rod in the spring damper 102 is located inside the mounting plate 2. When the display screen 1 is squeezed by an external object, the fixing block 101 on the inner wall of the display screen 1 transmits the pressure to the spring damper 102. The spring damper 102 buffers the display screen 1 and reduces the impact force of the external object on the display screen 1.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The top of the first locking block 402 is equipped with a limiting post 404, and the top of the limiting post 404 is located in the second connecting block 4. When the second locking block 5 presses the first locking block 402, the second connecting block 4 limits the movement of the first locking block 402 through the limiting post 404, so that the first locking block 402 moves up and down in the vertical direction.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 4The second card block 5 has a card slot 504 inside, and a fixing component is installed inside the card slot 504. The fixing component includes a fixing strip 502. The bottom of the fixing strip 502 is connected to a third spring 503. The third spring 503 pushes the fixing strip 502 into the card slot 504. The fixing strip 502 limits and fixes the second card block 5 in the first connecting block 3, so that the display screen 1 can move in a direction perpendicular to the fixed wall.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The inner wall of the slot 504 is inclined. The elastic coefficient of the third spring 503 is less than that of the second spring 501. After the person releases the display screen 1, the spring damper 102, which is in the compression spring, drives the squeezing column 505 to move out of the slot 504. The second spring 501, which is in the compression state, pushes the second locking block 5. Since the elastic coefficient of the second spring 501 is greater than that of the third spring 503 located at the bottom of the fixing bar 502, the moving speed of the second spring 501 pushing the second locking block 5 is greater than the speed of the third spring 503 pushing the fixing bar 502. As a result, when the fixing bar 502 has not risen to the bottom of the inner wall of the slot 502, the slot 504 is displaced to the side above the fixing bar 502 due to the movement of the second locking block 5.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 5 Two sets of fixing plates 507 are fixed on the inner wall of the display screen 1. The top of the fixing strip 502 is connected to the pressing column 505. The top of the pressing column 505 is connected to the fixing plate 507. When the person presses the display screen 1, the display screen 1 drives the pressing column 505 to move downward through the two sets of fixing plates 507 on its inner wall, so that the pressing column 505 presses the fixing strip 502 to the bottom of the second card block 5.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The inner wall of the fixed plate 507 is provided with a sliding groove 508, and the top outer wall of the extrusion column 505 is fixed with a connecting column 506. If the display screen 1 is tilted and pressed down, the connecting column 506 at the top of the extrusion column 505 slides in the sliding groove 508 on the inner wall of the fixed plate 507, so that the extrusion column 505 can still move vertically downward.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The total length of the mounting plate 2, the first connecting block 3, and the second connecting block 4 is equal to the width of the display screen 1. When the edges of the two sets of display screens 1 are aligned and in contact, the first connecting block 3 and the second connecting block 4 can make contact, which facilitates the subsequent snapping of the second clip 5 into the second connecting block 4.

[0044] In practical operation, the present invention works as follows: First, the two sets of display screens 1 are flattened and fixed, with their edges in contact. Then, one set of display screens 1 is pressed down. The display screen 1 compresses the spring damper 102 through the fixing block 101, and the display screen 1 moves the two sets of fixing plates 507 on the inner wall. The fixing plate 507 moves the pressing column 505 downward through the connecting column 506, so that the pressing column 505 presses the fixing strip 502 to the bottom of the second locking block 5. Then, after the personnel release the display screen 1, the spring damper 102, which is in the compressed spring state, moves the pressing column 505 out of the slot 504, and the second spring 501, which is in the compressed state, pushes the second locking block 5. Since the elastic coefficient of the second spring 501 is greater than that of the third spring 503 located at the bottom of the fixing strip 502, the spring damper 102, which is in the compressed spring state, moves the pressing column 505 out of the slot 504. The second spring 501, which is in the compressed state, pushes the second locking block 5. Therefore, the pushing force of the second spring 501 to push the second locking block 5 is greater than the pushing force of the third spring 503 to push the fixing strip 502. When the fixing strip 502 has not risen to the bottom of the inner wall of the slot 502, the slot 504 is displaced to the side above the fixing strip 502 due to the movement of the second locking block 5. The second locking block 5 is inserted into the slot 401 of the second connecting block 4. When the second locking block 5 contacts the first locking block 402, the second locking block 5 presses the first locking block 402 upward, so that the first locking block 402 compresses and contracts the first spring 403. When the second locking block 5 moves to the end of the inner wall of the slot 401, the first spring 403 in the compressed state pushes the first locking block 402 downward, so that the first locking block 402 latches and fixes the second locking block 5, thereby completing the combination splicing operation between the two sets of display screens 1.
