Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically a detachable LED display. Background Technology

[0002] Detachable LED displays, as the name suggests, are modular LED display products that are easy to install and disassemble. They are made up of independent modules, each of which is lightweight and portable and supports quick-locking fixation. This type of display has extremely high flexibility and can be freely adjusted in size according to the needs of the venue. It is widely used in stage rental, exhibitions, advertising and other fields. Compared with traditional LED screens, detachable LED displays are easier to maintain, save space, and reduce transportation costs. While ensuring high-definition display effects, they bring users a convenient user experience, making them an ideal choice for modern information dissemination.

[0003] A search revealed that Chinese utility model patent CN219716378U discloses a detachable LED display screen. This utility model places the mounting plate at the bottom of the LED display screen body into a slot on the frame, and inserts a rod through the slot on the frame into the rod slot on the mounting plate. This avoids the need for a large number of fasteners due to the large number of LED display screen bodies to be installed, and reduces the installation time of the LED display screen body.

[0004] However, there are some issues to consider when implementing the above technical solutions: First, the installation of the display screen is limited by the frame, making it impossible to quickly replace the LED display screen body. Second, multiple LED display screen bodies need to be connected. When connecting them according to different usage conditions, the length of the wires is not easy to control, and they are prone to tangling after storage, affecting subsequent use. Moreover, when not in use outdoors, impurities will enter the controller from the interface, affecting its lifespan. Utility Model Content

[0025] Please see Figure 1-4The present invention provides an embodiment of a detachable LED display screen, comprising a display screen 1 and a mounting mechanism 3. A controller 2 is provided on the front of the display screen 1, the mounting mechanism 3 is provided on the outside of the controller 2, an automatic wire retractor 302 is provided on the right side of the controller 2, a rotating shaft 305 is provided below the controller 2, a clamping groove 311 is provided below the rotating shaft 305, and limit blocks 313 are provided on both sides of the display screen 1.

[0026] Specifically, a sealing plug 301 is provided on the left side of the controller 2. The sealing plug 301 fits tightly with the interface of the controller 2. The sealing plug 301 is made of silicone rubber. The sealing plug 301 blocks the interface to prevent impurities from entering the controller 2 and affecting its lifespan when it is not in use outdoors.

[0027] Specifically, the internal part of the automatic retractor 302 is connected to one end of the wire 303, and the other end of the wire 303 is connected to the connector 304. The connector 304 can be connected to the interface of the controller 2 to pull the wire 303 out of the automatic retractor 302. The connector 304 is connected to the interface of other display screens 1 to synchronize data. When not in use, the automatic retractor 302 will retract the wire 303 to prevent tangling and facilitate subsequent use.

[0028] Specifically, a connecting rod 306 is provided on the outer side of the rotating shaft 305, and push rods 307 are connected to both sides of the connecting rod 306. Handles 308 are provided on both sides of the push rods 307. Dragging one side of the handle 308 moves the push rod 307. Through the linkage between the rotating shaft 305 and the connecting rod 306, the push rod 307 on the other side can move synchronously, which facilitates the movement of the clamping slot 311 during disassembly and assembly.

[0029] Specifically, a guide limit ring 309 is provided on the outer side of the push rod 307. Multiple sets of guide limit rings 309 are provided. The guide limit rings 309 are fixedly connected to the display screen 1. The guide limit rings 309 control the movement direction of the push rod 307 to prevent the clamping groove 311 from being misaligned.

[0030] Specifically, the bottom of the push rod 307 is connected to one end of the vertical rod 310, and the other end of the vertical rod 310 is connected to a clamping groove 311. A mounting bracket 312 is engaged inside the clamping groove 311. The mounting bracket 312 is connected to the working surface. The clamping groove 311 clamps the mounting bracket 312 to fix the display screen 1. When it is necessary to disassemble the display screen 1, the clamping groove 311 separates and releases the mounting bracket 312 to remove it, which is convenient and quick.

[0031] Specifically, the limiting block 313 is rotatably connected to the display screen 1. The two sides of the limiting block 313 have different widths, and the limiting block 313 can fit tightly with the handle 308. The front of the limiting block 313 is provided with a rotating handle 314. After the display screen 1 is installed, rotating the rotating handle 314 will fit the wider side of the limiting block 313 with the handle 308, so as to prevent the clamping groove 311 from loosening due to the movement of the handle 308 affected by the external environment, and prevent the display screen 1 from falling off.

[0032] Working principle: First, dragging one side handle 308 moves the push rod 307, which is linked to the connecting rod 306 via the rotating shaft 305, allowing the other side push rod 307 to move synchronously. This facilitates the movement of the clamping groove 311 during assembly and disassembly. The guide limit ring 309 controls the direction of movement of the push rod 307, preventing misalignment of the clamping groove 311. After the clamping groove 311 clamps the mounting bracket 312, it fixes the display screen 1. After the display screen 1 is installed, rotating the handle 314 aligns the wider side of the limit block 313 with the handle 308, preventing the handle 308 from being affected by external factors. 8. The activity causes the clamping slot 311 to loosen, preventing the display screen 1 from falling. When it is necessary to disassemble the display screen 1, the clamping slot 311 can be separated and the mounting bracket 312 can be released, which is convenient and quick. The wire 303 is pulled out from the automatic retractor 302, and the connector 304 is connected to the interface of other display screens 1 to synchronize data. When not in use, the automatic retractor 302 will retract the wire 303 to prevent tangling and facilitate subsequent use. Then, the sealing plug 301 is used to block the interface to prevent impurities from entering the controller 2 when it is not in use outdoors and affecting its lifespan.
