Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, and in particular to a connection structure at a seam of an LED display screen. Background Art

[0002] An LED display is a flat panel display consisting of small LED module panels. It is a device used to display various information such as text, images, and videos. The LED electronic display integrates microelectronics technology, computer technology, and information processing. It has the advantages of bright colors, wide dynamic range, high brightness, long life, and stable and reliable operation.

[0003] In the prior art, common LED screens are composed of several LED display cabinets spliced ​​together. When the screens are joined, if the gaps between them are too large, the spliced ​​area of ​​the LED screens may be larger than the spliced ​​area of ​​the frames. Simply pushing and squeezing the LED display cabinets to reduce the gaps could result in the LED screens being crushed and broken. Inventing a connection structure for the spliced ​​seams of LED screens to address these issues has become a pressing issue for those skilled in the art. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a connection structure at the joints of LED display screens, which aims to solve the common problem that when LED display screens are spliced ​​into place, the LED display screen box is pushed and squeezed to reduce the gap, causing breakage.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a connection structure at the seam of an LED display screen, comprising a display screen and a seam assembly arranged on the back of the display screen, wherein mounting grooves are provided at adjacent frames on both sides of the back of the display screen;

[0007] The seam assembly comprises a fixing frame, a mounting plate, an abutting plate and an adjusting screw, and the seam assembly is installed by inserting the mounting plate into the mounting slot.

[0008] Preferably, one end of the fixing bracket is fixedly connected to an outer wall of one side of the mounting plate, and a limiting groove is provided on the fixing bracket.

[0009] Preferably, a limit block is installed at the upper end of the abutment plate and is slidably connected to the inner wall of the limit groove. The outer wall of one end of the adjusting screw is rotatably connected to the inner wall of the mounting plate. The outer wall of the adjusting screw is threadedly connected to the inner wall of the abutment plate. A knob is installed at one end of the adjusting screw.

[0010] By adopting the above technical solution, after the sides of the display screens are aligned, one end of the splicing assembly is inserted into the mounting groove, and then the adjusting screw is turned to drive the abutment plate to move toward one side of the mounting plate until the abutment plate contacts the inner wall of the frame on the display screen. During the movement, the abutment plate and the mounting plate contract with each other between the two display screens, reducing the size of the gap, improving the appearance of the spliced ​​screen and preventing dust from falling into the gap.

[0011] Preferably, an extrusion groove is provided on an outer wall of the frame on one side of the display screen where no mounting groove is provided, a buffer groove is provided at one end of the extrusion groove, and a positioning groove penetrating the adjacent display screen frame is provided at one end of the buffer groove.

[0012] Preferably, the inner wall of the buffer groove is slidably connected with a buffer plate, a buffer spring fixedly connected to the inner wall of the buffer groove is installed on one side of the buffer plate, positioning rods are installed at both ends of the buffer plate, one end of the positioning rod is slidably connected to the inner wall of the positioning groove, and the other end of the positioning rod is installed with an extrusion plate slidably connected to the inner wall of the extrusion groove.

[0013] Preferably, an adjustment groove is provided on the inner wall adjacent to the display screen, a storage groove is provided at one end of the adjustment groove, an adjustment spring is installed on the inner wall of the adjustment groove, an adjustment plate is installed on the side wall at one end of the adjustment spring, an adjustment rod is installed at one end of the adjustment plate, and a positioning block is installed at one end of the adjustment rod that is slidably connected to the inner wall of the storage groove.

[0014] Preferably, one end of the positioning rod close to the positioning slot is cone-shaped, and one side of the positioning rod is provided with a positioning hole for plugging into the positioning block, and the side walls of the positioning hole and the positioning block are both inclined.

[0015] By adopting the above technical solution, during the movement of the abutment plate, the positioning rod is inserted into the positioning groove in the other display screen, and at the same time, the positioning block inside the receiving groove cooperates with the positioning hole to fix the positioning rod, thereby strengthening the fixation of the joint between the two display screens and improving the strength of the connection.

[0016] The beneficial effects of the utility model are:

[0017] The abutment plate provided on the seam assembly cooperates with the adjusting screw to quickly reduce the size of the gap between the display screens, thereby improving the installation efficiency and the overall appearance of the display screen after assembly. At the same time, the smaller gap effectively prevents some dust from entering the back of the screen from the connection of the display screen and causing damage to the components, thereby improving the service life of the display screen. The positioning block provided cooperates with the positioning groove to fix the position between two adjacent display screens, while maintaining the beauty of the seam, effectively avoiding the problem of misalignment between the display screens due to insufficient strength of the connection.
