Description

Technical Field

[0001] This utility model relates to the field of LED display module installation technology, and in particular to a module connection device suitable for ultra-thin LED displays. Background Technology

[0002] LED display modules, also known as unit boards, consist of LED light-emitting diodes, driver circuits, driver ICs, and plastic components. In the LED display industry, LED unit boards are currently divided into two main categories: indoor unit boards, generally referred to as surface-mount (SMD) boards, and outdoor and semi-outdoor unit boards, generally referred to as modules. Indoor SMD board characteristics include high image clarity and rich colors, but their price is relatively high. Outdoor and semi-outdoor module unit boards feature high brightness, waterproofing, and rich colors, but their installation requires technical guidance. When using LED display modules, they are typically installed in suitable locations using connecting devices.

[0003] Announcement No. CN215007325U discloses an LED display module connection device, including a display frame. An LED display screen for display is fixedly connected to the inner wall of the display frame. An extension frame for connection is fixedly connected to the back of the display frame. A rectangular groove for connection is opened on the back of the display frame. Connecting devices are fixedly connected to the four corners of the back of the display frame. A positioning bracket for positioning is fixedly connected to the inner wall of the extension frame. A sealing cover plate for sealing is provided on the back of the extension frame. A positioning rod passing through the positioning bracket is fixedly connected to the front of the sealing cover plate.

[0004] The aforementioned LED display module connection device controls the annular rotating tube to drive the rotating vertical plate and rotating disc to drive the pressing inclined block to move inward and press the front side of the plug-in column, thereby quickly releasing the fixing of the plug-in column and facilitating faster disassembly and assembly of the display frame and sealing cover. However, this device requires rotating the annular rotating tube four times to release the disassembly and assembly of the display frame and sealing cover. After the sealing cover is released, the display frame and LED display are fixedly connected, making it inconvenient to disassemble the LED display. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a module connection device suitable for ultra-thin LED displays.

[0006] This utility model is achieved by the following technical solution: a module connection device suitable for ultra-thin LED displays, including a sliding mechanism, a rotating mechanism inside the sliding mechanism, and a fixing mechanism inside the sliding mechanism;

[0007] The sliding mechanism includes a frame, inside which is an LED display module body. A sealing cover is inserted into the inner wall of the frame. Sliding grooves are provided on the left and right sides of the front end of the sealing cover. A guide rod is fixedly connected to the inner wall of the sliding groove. An insert plate is slidably connected to the surface of the guide rod. A first spring is fixedly connected to one side of the insert plate. A second spring is fixedly connected inside the insert plate. A stop block is fixedly connected to one side of the second spring.

[0008] Through the above technical solution, the second spring stores energy when the rotating rod presses the insert plate, and releases energy after the rotating rod stops applying pressure, pushing the stop block to extend and lock the rotating rod.

[0009] As a further improvement to the above solution, grooves are provided on the left and right sides of the inner wall of the frame, and the grooves of the inner wall of the frame are inserted into one side of the insert plate.

[0010] As a further improvement to the above solution, the inner wall of the sliding groove is slidably connected to the bottom surface of the insert plate, one side of the sliding groove is fixedly connected to one side of the first spring, the guide rod is located inside the first spring, a groove is provided on one side of the insert plate, and the inner wall of the insert plate is slidably connected to the surface of the stop block.

[0011] As a further improvement to the above solution, the rotating mechanism includes a handle, a rotating rod is fixedly connected to the front end of the handle, a limiting block is fixedly connected to the rear end of the rotating rod, and a limiting groove is provided at the front end of the sealing cover.

[0012] With the above technical solution, the throttle handle serves as the operating component, allowing the operator to manually rotate it to drive the rotating rod, thereby controlling the movement and locking state of the insert plate. The operation is simple, requiring no other tools, and is convenient for installation and disassembly.

[0013] As a further improvement to the above solution, the throttle is located at the rear end of the sealing cover plate, the throttle is rotatably connected to the inside of the sealing cover plate, and two limiting grooves are provided, with the inner wall of the limiting groove slidably connected to the surface of the limiting block.

[0014] With the above technical solution, the two limiting grooves are located between the two sliding grooves. The limiting grooves are opened at the front end of the sealing cover plate and cooperate with the limiting block to precisely limit the rotation range of the rotating rod, prevent the rotating rod from rotating arbitrarily, and ensure the stability of the insertion and disengagement of the insert plate.

[0015] As a further improvement to the above solution, the fixing mechanism includes a fixing box, a third spring is fixedly connected to the rear end of the inner wall of the fixing box, and a fixing plate is fixedly connected to the front end of the third spring.

[0016] As a further improvement to the above solution, the fixing box is located at the front end of the sealing cover plate, the rear end of the fixing box is fixedly connected to the front end of the sealing cover plate, the inner wall of the fixing box is slidably connected to the surface of the fixing plate, and the number of fixing boxes is set to four, which are symmetrically and evenly distributed around the front end center of the sealing cover plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features a rotating rod. When the handle is rotated in the opposite direction, the rotating rod causes the limiting block to rotate in the opposite direction within the limiting groove. The rotating rod presses against the stop block, releasing the block's obstruction. The first spring then quickly rebounds, easily pulling the insert plate out of the groove in the inner wall of the frame. Subsequently, the sealing cover can be pulled out from the inner wall of the frame without any obstruction, allowing for the quick removal of the LED display module body. This significantly saves installation and maintenance time and labor costs, effectively ensures the continuous and stable operation of the display screen, reduces costs associated with installation, debugging, and maintenance, and improves project implementation efficiency.

[0019] This invention features a fixing plate whose front end fits tightly against the rear end of the LED display module body. The rear end gradually compresses a third spring within the fixing box. The elastic potential energy of the spring provides cushioning and assistance for the sealing cover to be smoothly inserted into the frame. This design can accommodate LED display modules of various thicknesses, sizes, and interface layouts. It eliminates the need to design separate connection schemes for different modules, reducing production costs and enhancing the product's adaptability to various application scenarios.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 This embodiment provides a module connection device suitable for ultra-thin LED displays, including a sliding mechanism 1, a rotating mechanism 2 inside the sliding mechanism 1, and a fixing mechanism 3 inside the sliding mechanism 1.

[0030] The sliding mechanism 1 includes a frame 101, inside which is an LED display module body 102. A sealing cover 103 is inserted into the inner wall of the frame 101. Sliding grooves 104 are provided on the left and right sides of the front end of the sealing cover 103. A guide rod 105 is fixedly connected to the inner wall of the sliding groove 104. An insert plate 106 is slidably connected to the surface of the guide rod 105. A first spring 107 is fixedly connected to one side of the insert plate 106. A second spring 108 is fixedly connected inside the insert plate 106. A stop block 109 is fixedly connected to one side of the second spring 108. Under the guidance of the guide rod 105, the insert plate 106 compresses the first spring 107, moves to both sides, and inserts into the groove of the inner wall of the frame 101 to achieve connection.

[0031] Grooves are provided on the left and right sides of the inner wall of the frame 101, and the grooves on the inner wall of the frame 101 are inserted into one side of the insert plate 106.

[0032] The inner wall of the sliding groove 104 is slidably connected to the bottom surface of the insert plate 106. One side of the sliding groove 104 is fixedly connected to one side of the first spring 107. The guide rod 105 is located inside the first spring 107. A groove is provided on one side of the insert plate 106. The inner wall of the insert plate 106 is slidably connected to the surface of the stop block 109.

[0033] The rotating mechanism 2 includes a handle 201, with a rotating rod 202 fixedly connected to the front end of the handle 201. A limiting block 203 is fixedly connected to the rear end of the rotating rod 202. A limiting groove 204 is provided at the front end of the sealing cover plate 103. Rotating the handle 201 causes the rotating rod 202 to rotate 90 degrees, and the limiting block 203 rotates within the limiting groove 204. The rotating rod 202 presses against the insert plate 106.

[0034] The throttle 201 is located at the rear end of the sealing cover 103. The throttle 201 is rotatably connected to the inside of the sealing cover 103. There are two limiting grooves 204. The inner wall of the limiting groove 204 is slidably connected to the surface of the limiting block 203.

[0035] The fixing mechanism 3 includes a fixing box 301. A third spring 302 is fixedly connected to the rear end of the inner wall of the fixing box 301. A fixing plate 303 is fixedly connected to the front end of the third spring 302. The front end of the fixing plate 303 is close to the rear end of the module body, and the rear end compresses the third spring 302 inside the fixing box 301 to help insert the sealing cover plate.

[0036] The fixed box 301 is located at the front end of the sealing cover plate 103. The rear end of the fixed box 301 is fixedly connected to the front end of the sealing cover plate 103. The inner wall of the fixed box 301 is slidably connected to the surface of the fixed plate 303. There are four fixed boxes 301, which are symmetrically and evenly distributed around the front center of the sealing cover plate 103.

[0037] The implementation principle of a module connection device for ultra-thin LED displays in this embodiment is as follows: When installing the LED display module body 102, it is first placed stably inside the frame 101. Then, the sealing cover 103 is slowly inserted into the inner wall of the frame 101. During this process, the front end of the fixing plate 303 will closely fit the rear end of the LED display module body 102, while the rear end gradually compresses the third spring 302 inside the fixing box 301. With the help of the elastic potential energy of the spring, the sealing cover 103 is cushioned and assisted in smoothly inserting into the frame 101.

[0038] Once the sealing cover 103 is in place, the handle 201 is rotated. The rotation of the handle 201 causes the rotating rod 202 to rotate precisely 90 degrees. Simultaneously, the limiting block 203 at the rear end of the rotating rod 202 rotates flexibly within the limiting groove 204. As the rotating rod 202 rotates, it gradually presses against the insert plates 106. Guided by the guide rod 105, the two insert plates 106 begin to compress the first spring 107, and then move smoothly to both sides within the sliding groove 104, ultimately precisely inserting into the grooves on the inner wall of the frame 101, achieving a secure connection.

[0039] It is worth noting that while the rotating rod 202 is pressing against the insert plate 106, it also exerts pressure on the stop block 109, causing the stop block 109 to compress the second spring 108 and retract into the inner wall of the insert plate 106. After the rotating rod 202 completes a 90-degree rotation, it no longer applies pressure to the stop block 109. At this point, the second spring 108 quickly rebounds, pushing the stop block 109 outwards. The extended stop block 109 effectively blocks the rotating rod 202, while the limiting groove 204 effectively blocks the limiting block 203, preventing it from continuing to rotate. This avoids the rotating rod 202 from rotating arbitrarily, ensuring the stability and reliability of the entire connecting device.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
