Description

Technical Field

[0001] This utility model relates to the field of electronic display equipment technology, specifically a modular splicing LED display device. Background Technology

[0002] With the rapid development of LED display technology, modular splicing LED display devices have been widely used in advertising media, stage performances, smart cities and other fields due to their advantages such as flexible size adjustment, high brightness and long life.

[0003] Traditional devices often use screw fixing or snap-fit ​​connections. Screw fixing requires tools to disassemble and assemble modules one by one, which is cumbersome, inefficient, and prone to problems such as stripped screws and damaged screw holes due to frequent disassembly and assembly. Although snap-fit ​​connections simplify the installation process, they are prone to loosening and falling off due to external impacts or vibrations during long-term use, which can lead to decreased display stability and even the risk of falling off. At the same time, traditional devices lack effective auxiliary structures, making it difficult to quickly separate the module from the frame when a faulty module needs to be replaced. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figure 1-4 This utility model provides a technical solution: a modular splicing LED display device, comprising:

[0024] The frame 1 and the LED display screen 2 are slidably connected. The inner wall of the frame 1 and the outer wall of the LED display screen 2 are slidably connected. The inner wall of the frame 1 is slidably connected with a locking device 3, which locks the LED display screen 2 by sliding. The inner wall of the frame 1 is fixedly connected with an auxiliary device 4. When in use, the LED display screen 2 is placed on the inner wall of the frame 1 and fixed by the locking device 3. When it needs to be replaced, it is popped out by the auxiliary device 4.

[0025] The locking device 3 includes a locking block 30, a lever 31 fixedly connected to the outer wall of the locking block 30, a beveled area on the outer wall of the locking block 30, and a first compression spring 32 symmetrically fixedly connected to the outer wall of the locking block 30. The outer wall of the locking block 30 is symmetrically slidably connected to the inner wall of the frame 1, and the outer wall of the beveled area is slidably connected to the outer wall of the LED display screen 2. The end of the first compression spring 32 away from the locking block 30 is fixedly connected to the inner wall of the frame 1. First, the LED display screen 2 is inserted along the sliding track of the inner wall of the frame 1, and the outer wall of the display screen is connected to the beveled area of ​​the locking block 30. When the LED display screen 2 slides, the locking block 30 is in a state close to the inner wall of the frame 1 under the initial elastic force of the first compression spring 32. As the LED display screen 2 continues to slide, its outer wall applies a horizontal pushing force to the inclined area of ​​the locking block 30, pushing the locking block 30 to slide towards the inner wall of the frame 1 against the elastic force of the first compression spring 32. When the display screen slides into place, the groove at the corresponding position of the locking block 30 aligns with the protrusion or slot on the outer wall of the display screen. The first compression spring 32 quickly releases its elastic force, pushing the locking block 30 to pop out and lock into the groove, thereby realizing the automatic locking of the display screen.

[0026] The inner wall of the locking block 30 is slidably connected to a limiting rod 33, and the outer wall of the limiting rod 33 is fixedly connected to a limiting plate 34. The end of the limiting rod 33 away from the limiting plate 34 is fixedly connected to the inner wall of the frame 1, and the outer wall of the limiting plate 34 is slidably connected to the inner wall of the frame 1. During the sliding of the LED display screen 2, the limiting rod 33 is fixedly connected to the outer wall of the locking block 30, and the limiting plate 34 is fixedly connected to the outer wall of the limiting rod 33. The limiting plate 34 is slidably connected to the inner wall of the frame 1. The limiting rod 33 and the limiting plate 34 limit the sliding stroke of the locking block 30. During the operation of the device, the limiting rod 33 and the limiting plate 34 continuously constrain the position of the locking block 30. When the device is subjected to vibration or external impact, the limiting structure can prevent the locking block 30 from sliding abnormally or popping out. With the buffering effect of the first compression spring 32, the stable connection of the display screen is maintained, and the vibration resistance of the device is improved.

[0027] The auxiliary device 4 includes a push plate 40, on the outer wall of which a second compression spring 41 is fixedly connected. The outer wall of the second compression spring 41 is arranged in a row along the circumference of the central axis of the push plate 40. The end of the push plate 40 away from the second compression spring 41 is in contact with the outer wall of the LED display screen 2, and the end of the second compression spring 41 away from the push plate 40 is fixedly connected to the inner wall of the frame 1. By moving the lever 31 hidden inside the frame 1, the maintenance personnel can drive the locking block 30 to slide against the elastic force of the first compression spring 32 towards the inner wall of the frame 1, so that the locking block 30 is disengaged from the groove of the display screen and the locked state is released. The push plate 40 and the second compression spring 41 of the auxiliary device 4 form an elastic support system. In daily use, the second compression spring 41 is in a slightly compressed state, providing continuous elastic support force for the display screen. When the device is subjected to external impact, the spring can absorb the impact force through compression deformation, reducing the hard collision between the display screen and the frame 1 and reducing the risk of screen damage.

[0028] When in use, the LED display screen 2 is placed on the inner wall of the frame 1 and fixed by the locking device 3. When it needs to be replaced, it is popped out by the auxiliary device 4.

[0029] First, the LED display screen 2 is inserted along the sliding track on the inner wall of the frame 1. The outer wall of the display screen contacts the inclined area of ​​the locking block 30. At this time, the locking block 30 is in a state close to the inner wall of the frame 1 under the initial elastic force of the first compression spring 32. As the LED display screen 2 continues to slide, its outer wall applies a horizontal pushing force to the inclined area of ​​the locking block 30, pushing the locking block 30 to slide towards the inner wall of the frame 1 against the elastic force of the first compression spring 32. When the display screen slides into place, the groove at the corresponding position of the locking block 30 aligns with the protrusion or slot on the outer wall of the display screen. The first compression spring 32 quickly releases its elastic force, pushing the locking block 30 to pop out and lock into the groove, thus realizing the automatic locking of the display screen.

[0030] During the sliding process of the LED display screen 2, a limiting rod 33 is fixedly connected to the outer wall of the locking block 30, and a limiting plate 34 is fixedly connected to the outer wall of the limiting rod 33. The limiting plate 34 is slidably connected to the inner wall of the frame 1. The limiting rod 33 and the limiting plate 34 limit the sliding stroke of the locking block 30. During the operation of the device, the limiting rod 33 and the limiting plate 34 continuously constrain the position of the locking block 30. When the device is subjected to vibration or external impact, the limiting structure can prevent the locking block 30 from sliding abnormally or popping out. With the buffering effect of the first compression spring 32, the stable connection of the display screen is maintained, and the vibration resistance of the device is improved.

[0031] Maintenance personnel can move the lever 31 hidden inside the frame 1 to make the locking block 30 slide against the inner wall of the frame 1 against the elastic force of the first compression spring 32, so that the locking block 30 disengages from the groove of the display screen and is released from the locked state. The push plate 40 of the auxiliary device 4 and the second compression spring 41 form an elastic support system. In daily use, the second compression spring 41 is in a slightly compressed state, providing continuous elastic support force for the display screen. When the device is subjected to external impact, the spring can absorb the impact force through compression deformation, reduce the hard collision between the display screen and the frame 1, and reduce the risk of screen damage.
