[0004] This inefficient installation and disassembly method not only increases labor and time costs, but also affects splicing accuracy and display effects, failing to meet the actual needs of modern display applications for rapid deployment and flexible adjustment. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a seamless splicing LED display screen to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a seamless LED display screen, including a support frame, a main screen fixedly mounted on the support frame, connecting arms connected to the support frame, multiple sets of connecting arms, each with a secondary screen rotatably mounted at its top, fixing plates fixedly mounted on both sides of the main screen, side plates fixedly mounted on both sides of the multiple sets of secondary screens, and multiple fixing mechanisms mounted on the fixing plates and side plates, each fixing mechanism including a fixing sleeve and a plug rod, the fixing sleeve being fixed to the outside of the fixing plate, and the plug rod... Fixed to the side plate, the inner wall of the fixing sleeve has sliding holes, and each sliding hole has multiple sets of locking blocks that slide on their inner sides. Each set of locking blocks has a sliding rod fixed at its top, and each set of sliding rods slides to the outer wall of the fixing sleeve and has a mating block fixed at its top. The outer wall of the insertion rod has slots, and each set of slots abuts against multiple sets of locking blocks. The outer wall of the fixing sleeve has a sliding sleeve, and the outer side of the sliding sleeve has an inclined groove, and each set of inclined grooves slides to the multiple sets of mating blocks. The fixing plate has insertion holes, and multiple sets of insertion holes are provided.

[0009] The present invention is further configured such that a push spring is connected between the top surface of the multiple sets of card blocks and the inner wall of the sliding hole. The push spring provides a continuous and stable elastic force so that the card blocks can automatically extend and be firmly locked into the card slot, ensuring reliable locking of the connection points during the splicing of the LED display screen, improving the connection strength and stability, and simplifying the operation steps to make splicing more convenient and efficient.

[0010] The present invention is further provided with a tension spring connecting the outer side of the sliding sleeve and the fixed sleeve. After the tension spring is released, it can automatically pull the sliding sleeve back to its original position, thereby realizing the automated operation of the unlocking process. The retraction of the locking block can be completed without manual intervention, which greatly improves the disassembly efficiency and ensures the smooth and controllable unlocking action.

[0011] The present invention is further configured such that a slider is fixedly provided on the inner side of the sliding sleeve, and a groove is provided on the outer wall of the fixed sleeve. Multiple sets of sliders and grooves are provided and slidably connected. The cooperative design of sliders and grooves provides the sliding sleeve with a precise motion trajectory and guiding function, preventing the sliding sleeve from shifting or rotating during movement, ensuring the high-precision operation of the unlocking mechanism, and improving the operational reliability and service life of the entire device.

[0012] The present invention is further configured such that a limiting block is provided on the outer wall of the sliding sleeve, and multiple sets of the limiting block are provided, with a return spring connected between the top of each limiting block and the outer wall of the sliding sleeve. A limiting groove is provided on the outer wall of the fixed sleeve, and multiple sets of the limiting groove are provided, each abutting against multiple sets of limiting blocks. The precise cooperation between the limiting block and the limiting groove achieves reliable locking of the sliding sleeve position, preventing accidental unlocking due to vibration or external force during the display process. The design of the return spring allows the limiting block to automatically rebound when unlocked, simplifying the operation process and improving the safety performance of the device.

[0013] The present invention is further configured such that a rotating sleeve is rotatably provided on the outer wall of the fixed sleeve, and a limiting plate is fixedly provided on the outer wall of the rotating sleeve. The limiting plate is provided in multiple sets and abuts against the top of multiple sets of limiting blocks respectively. The combination design of the rotating sleeve and the limiting plate allows the operator to control the unlocking state of all limiting blocks with a simple rotation action, realizing a "one-click" operation experience, greatly simplifying the disassembly process, improving work efficiency, and ensuring that all connection points are unlocked simultaneously, avoiding disassembly difficulties caused by some connection points still being locked.

[0014] The present invention is further configured such that a pressing block is fixedly provided on the bottom surface of the rotating sleeve, and a baffle is fixedly provided on the outer wall of the fixed sleeve. Multiple sets of pressing blocks and baffles are provided and connected to each other by pressing springs. The combination design of pressing springs, pressing blocks, and baffles provides an automatic reset function for the rotating sleeve. When the operator releases the rotating sleeve, the pressing spring will automatically push the rotating sleeve back to the locked position to ensure that the system is always in a safe locked state. At the same time, it also provides clear tactile feedback to the operator, improving the intuitiveness and safety of operation.

[0015] The present invention is further configured such that both ends of the multiple sets of limiting blocks are rounded, and the outer sides of the multiple sets of limiting plates are rounded. The rounded limiting blocks and the rounded limiting plates allow them to slide smoothly during contact and separation, avoiding sharp corner collisions and jamming. This not only improves the smoothness and comfort of operation, but also reduces the wear of parts and extends the service life of the device, reflecting the humanization and refinement of the product design.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a seamless LED display screen, which has the following advantages:

[0018] 1. This device adopts an innovative quick-connect structure of insert rod and fixing sleeve. Through the precise cooperation of the locking block and the slot, a firm connection between LED displays is achieved. There is no need to use complicated tools and cumbersome steps. The operator only needs to insert the insert rod into the fixing sleeve and rotate the sleeve. The internal elastic element will automatically make the locking block lock into the slot, which greatly simplifies the installation process and improves splicing efficiency. At the same time, the design of multiple connection points ensures the precise alignment and stability of the splicing interface. It perfectly solves the problems of low installation efficiency and complicated steps in the existing technology and meets the urgent needs of large venues for rapid deployment of LED displays.

[0019] 2. This device features a unique unlocking mechanism. By rotating the rotating sleeve, the limiting plate releases its contact with the limiting block. A return spring drives the limiting block to disengage from the limiting groove. Subsequently, a tension spring automatically pulls the sliding sleeve, causing the mating block to slide along the inclined groove and pull the locking block out of the slot via a sliding rod. This achieves one-click quick unlocking of the connection between LED displays. The entire process is smooth and efficient, requiring no professional skills or complex tools, significantly reducing disassembly time and labor costs. The device also features multiple safety mechanisms to prevent accidental unlocking during display, balancing ease of operation and safety.

[0020] 3. The overall structure of this device is compact and reasonable.
