Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED displays, and more specifically, it relates to a splicing LED display. Background Technology
[0002] An LED display screen is an electronic display device that displays images, videos, or text information by controlling the brightness and color of semiconductor light-emitting diodes. Its core consists of a large array of LED pixels, each pixel achieving full-color display through a combination of the three primary colors: red, green, and blue. Compared to traditional display technologies, LED displays offer advantages such as high brightness, high contrast, wide viewing angle, long lifespan, and adaptability to complex environments, making them widely used in advertising media, stage performances, stadiums, traffic control, security monitoring, and conference systems.
[0003] Traditional single-panel LED displays are limited in size due to manufacturing processes and transportation / installation conditions, making it difficult to meet the needs of large-scale display scenarios such as giant cinema screens and large-scale exhibitions. Multi-panel LED displays, on the other hand, combine multiple standard-sized LED display units (cabinets or modules) through physical splicing to form display areas of any size. This modular design not only breaks through the limitations of single-screen size but also offers advantages such as flexible adaptation to installation space, ease of transportation and maintenance, and support for partial fault replacement, making it the mainstream solution in the large-screen display field.
[0004] Although splicing technology is relatively mature, its heat dissipation architecture and modular maintenance design still have some shortcomings. When multiple displays are spliced, poor heat dissipation design may cause localized overheating, accelerating LED degradation. The installation and maintenance process of existing splicing screens is relatively complex. The cabinets are mostly locked with screws, and installation or disassembly requires special tools and individual operation, which is inefficient, time-consuming, and labor-intensive. Therefore, there is an urgent need to design a splicing LED display to solve the above problems. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] In view of the problems existing in the prior art, this utility model provides a splicing LED display screen to solve the technical problems mentioned in the background art, such as poor heat dissipation design leading to LED attenuation and low disassembly efficiency.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A splicing LED display screen includes a display screen, a heat dissipation mechanism, a first connecting mechanism, and a second connecting mechanism. The display screens are connected to each other via the first connecting mechanism. The first connecting mechanism includes a first fixing block and a second fixing block. The first fixing block is connected to the display screen via a first locking bolt. A first locking block is connected to one side of the first fixing block. A first sliding groove is formed on the side wall of the second fixing block. The first locking block is slidably connected to the first sliding groove. An elastic telescopic component is provided in the first sliding groove. The second connecting mechanism includes a support column, a connecting block, a locking component, and a reset component. A reset groove is formed on the side wall of the support column. The reset component is disposed in the reset groove. The connecting block is fixedly connected to the side wall of the support column. One side of the locking component is fixedly connected to the display screen, and the other side is locked to the connecting block. The heat dissipation mechanism is connected to the display screen.
[0010] This invention is further configured such that the heat dissipation mechanism includes a heat sink, heat dissipation fins, a cooling fan, and a frame. One side of the heat sink is connected to the display screen, and the other side is connected to the heat dissipation fins. A cooling fan is positioned at the center of each heat dissipation fin, and the frame is connected to the outer side of the cooling fan. The frame is connected to the heat sink via a second locking bolt. After absorbing heat, the heat sink dissipates it through the heat dissipation fins and the cooling fan. The cooling fan forces airflow through the gaps between the heat dissipation fins, accelerating the heat dissipation rate. Simultaneously, the frame can be disassembled separately for easy cleaning of the cooling fan.
[0011] This invention is further configured such that the elastic telescopic assembly comprises two sets, each including a second locking block, a fixed rod, a sliding rod, a first spring, and an adjusting rod. One end of the first spring is fixedly connected to the inner wall of the first slide groove, and the other end is fixedly connected to the second locking block. A fixed rod and a sliding rod are disposed at the center of the first spring. One end of the fixed rod is fixedly connected to the inner wall of the first slide groove, and the other end is slidably connected to the sliding rod. The other end of the sliding rod is fixedly connected to the second locking block. An adjusting rod is connected to the side wall of the second locking block, and the adjusting rod is slidably connected to the second fixed block. By pushing the adjusting rod, the first spring is compressed, thereby causing the second locking block to slide in the first slide groove. The fixed rod and the sliding rod cooperate to restrict the direction of movement of the first spring, preventing deflection.
[0012] The present invention is further configured such that the reset assembly includes a reset block, a third spring, and a push rod. The reset block is disposed within a reset groove and slidably connected to the reset groove. A push rod is connected to one side of the reset block and slidably connected to a support column. The third spring is symmetrically disposed on the side wall of the reset block about the push rod, and the other end of the third spring is connected to the side wall of the reset groove. Pressing the push rod can drive the reset block to slide along the reset groove.
[0013] This utility model is further configured such that the snap-fit assembly is symmetrically arranged in two sets about the connecting block, including a third fixing block, a second spring, and a third locking block. The third fixing block is fixedly connected to the back of the display screen, and one side of the third fixing block is connected to the connecting block. A second sliding groove is formed on the side wall of the third fixing block, and the second spring is disposed in the second sliding groove. One end of the second spring is connected to the inner wall of the second sliding groove, and the other end is connected to the third locking block. The third locking block is slidably connected to the second sliding groove. Pressing the push rod causes the reset block to abut against the third locking block, driving the snap-fit assembly to disengage from the connecting block, thus achieving disassembly.
[0014] The present invention is further configured such that the side wall of the connecting block has four slots, and one side has a third sliding groove. The third locking block is slidably connected to the slots, and the reset block is slidably connected to the third sliding groove. The third locking block and the reset block are slidably connected to the connecting block through the slots and the third sliding groove, which facilitates pressing and disassembly.
[0015] This invention is further configured such that the third fixing block has two upper and lower second sliding grooves, and both the second spring and the third locking block have two sets of upper and lower grooves. The double sliding grooves share the mechanical stress, extend the service life, and make the connection more stable.
[0016] (III) Beneficial Effects
[0017] Compared with the prior art, the present invention provides a splicing LED display screen, which has the following advantages:
[0018] 1. This utility model is equipped with a first connecting mechanism, which achieves flexible locking through the sliding engagement of a first fixing block and a second fixing block, combined with an elastic telescopic component. During installation, pushing the adjusting rod causes the second locking block to slide, and after alignment, the spring pressure automatically locks it in place; during disassembly, the display screen can be separated by reversing the operation. This enables rapid splicing and disassembly of display screens, while the adjusting rod provides flexible preload adjustment to adapt to complex working conditions.
[0019] 2. This utility model is provided with a second connecting mechanism. The third locking block on the back of the display screen is embedded into the slot of the connecting block under the action of the second spring, so that the display screen and the support column are mechanically locked. Pressing the push rod drives the reset block to slide, pushing the third locking block out of the slot, realizing one-click disassembly, which is convenient for safe maintenance or disassembly and transportation.
[0020] 3. This utility model is equipped with a heat dissipation mechanism. The heat dissipation plate is in close contact with the back of the display screen to conduct heat, the heat dissipation fins expand the heat dissipation area, and the cooling fan forces airflow to accelerate heat dissipation. The frame can be disassembled independently, which is convenient for cleaning or replacing the fan. Attached Figure Description

The heat dissipation fins 11 increase the heat dissipation area, and the cooling fan 12 forces airflow through the gaps in the heat dissipation fins 11, accelerating heat dissipation. The frame 13 is detachable, facilitating the cleaning or replacement of the cooling fan 12.
[0033] In a further embodiment, the elastic telescopic assembly is provided in two sets. The elastic telescopic assembly includes a second locking block 15, a fixed rod 16, a sliding rod 17, a first spring 18, and an adjusting rod 19.

The adjusting rod 19 is connected to the side wall of the second locking block 15, and the adjusting rod 19 is slidably connected to the second fixed block 3.
[0034] By pushing the adjusting rod 19, the first spring 18 is compressed, which in turn causes the second locking block 15 to slide in the first slide groove 6, thereby releasing the restriction on the first locking block 5. The two display screens 1 can be disassembled and separated. The fixing rod 16 and the sliding rod 17 cooperate to restrict the movement direction of the first spring 18 and prevent it from tilting.
[0035] In a further embodiment, the reset assembly includes a reset block 20, a third spring 21, and a push rod 22. The reset block 20 is disposed in the reset groove 9 and slidably connected to the reset groove 9.

The third fixing block 23 is fixedly connected to the back of the display screen 1. One side of the third fixing block 23 is connected to the connecting block 8. A second sliding groove 26 is opened on the side wall of the third fixing block 23. The second spring 24 is disposed in the second sliding groove 26. One end of the second spring 24 is connected to the inner wall of the second sliding groove 26 and the other end is connected to the third snap-fit block 25. The third snap-fit block 25 is slidably connected to the second sliding groove 26.
[0037] When the display screen 1 needs to be connected to the support column 7, the third locking block 25 is embedded in the slot 27 of the connecting block 8 under the action of the second spring 24 to achieve mechanical locking. When disassembly is required, the push rod 22 is pressed to drive the reset block 20 to slide along the reset slot 9, and the reset block 20 pushes the third locking block 25 out of the slot 27 to release the lock.
[0038] In a further embodiment, the connecting block 8 has four slots 27 on its sidewall and a third sliding groove 28 on one side. The third locking block 25 is slidably connected to the slots 27, and the reset block 20 is slidably connected to the third sliding groove 28. The third fixing block 23 has two upper and lower second sliding grooves 26, and the second spring 24 and the third locking block 25 are each provided with two sets, one upper and one lower. The third locking block 25 and the reset block 20 are slidably connected to the connecting block 8 through the slots 27 and the third sliding groove 28, which facilitates pressing and disassembly; the double sliding grooves share the mechanical stress, extend the service life, and make the connection more stable.
[0039] In summary, when using the overall equipment:
[0040] In this invention, the first connecting mechanism is mainly used to achieve horizontal splicing of adjacent display screens 1, and mainly consists of a first fixing block 2, a second fixing block 3, and an elastic telescopic component. During splicing, the first fixing block 2 is fixed to the side of the display screen 1 by the first locking bolt 4, and the first locking block 5 connected to it is embedded in the first sliding groove 6 on the side wall of the second fixing block 3. Pushing the adjusting rod 19 causes the second locking block 15 to slide. After the first locking block 5 is in place, the adjusting rod 19 is released, and the pressure of the first spring 18 pushes the second locking block 15 to press against the first locking block 5, forming a flexible lock. During disassembly, pushing the adjusting rod 19 compresses the first spring 18, so that the second locking block 15 is released from the restriction of the first locking block 5, and the two display screens can be slidably separated.
[0041] The second connecting mechanism is used for the longitudinal fixation of the display screen 1 and the support column 7. The third fixing block 23 on the back of the display screen 1 is close to the connecting block 8. The third locking block 25 automatically embeds into the slot 27 of the connecting block 8 under the action of the second spring 24, completing the mechanical locking. The reset block 20 is in the reset slot 9. The third spring 21 keeps the locking state stable. When disassembling, press the push rod 22 to drive the reset block 20 to slide along the third sliding groove 28, push the third locking block 25 to disengage from the slot 27, and the display screen 1 can be separated from the support column 7.
[0042] The heat dissipation mechanism consists of a heat sink 10, heat sink fins 11, a cooling fan 12, and a detachable frame 13. The heat sink 10 directly contacts the back of the display screen 1 and conducts heat to the heat sink fins 11. The heat sink fins 11 increase the heat dissipation area. The cooling fan 12 forces airflow through the gaps in the heat sink fins 11 to accelerate heat dissipation. The frame 13 is detachable, which facilitates the cleaning or replacement of the cooling fan 12.
