Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to a device for fixing a seam-jointed LED display screen. Background Art

[0002] LED display is a flat panel display composed of small LED module panels. It is used to display text, images, videos and other information. It integrates microelectronics technology, computer technology and information processing. It has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation. LED display is widely used in commercial media, cultural performance market, sports stadiums, information dissemination, news release, securities trading, etc., and can meet the needs of different environments.

[0003] After searching: Patent number CN218543801U is a device for adjusting and fixing the transverse seam of an LED display screen, comprising a frame, the frame comprising a mounting frame, the inner side of the mounting frame is provided with a mounting groove; the inner side of the mounting groove is provided with an adjustment mechanism, the adjustment mechanism comprising a movable groove. The utility model can adjust the position of the movable rod by pinching the movable rod so that the second sawtooth cancels the meshing with the first sawtooth under the action of the movable rod, and then the movable rod drives the second sawtooth to reset through the action of the first spring, so that the first sawtooth and the second sawtooth are engaged, so as to achieve the effect of fixing the movable rod, and then the position of the connecting plate can be adjusted and fixed.

[0004] However, the above-mentioned LED display screen transverse seam adjustment and fixing device still has some shortcomings. Although the transverse seams between the LED display screens can be adjusted, it is inconvenient to adjust the vertical seams between the LED display screens, which makes the vertical seam gaps between the LED display screens larger and reduces the display effect of the LED display screen. In addition, during the above-mentioned adjustment, personnel need to pull two movable rods and one insertion rod before pulling the movable rod to adjust and fix it. It requires multiple people to work together, which makes the adjustment and fixation more troublesome and inconvenient. Therefore, we propose a seam splicing LED display screen fixing device to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A device for fixing a spliced ​​LED display screen comprises a frame 1, two horizontal plates 2 and two vertical plates 3 for fixing and installing the spliced ​​LED display screen. A horizontal seam adjustment and squeezing mechanism is arranged between the frame 1 and the two horizontal plates 2, a vertical seam adjustment and squeezing mechanism is arranged between the frame 1 and the two vertical plates 3, and a height self-adjusting mechanism is arranged on the vertical plates 3.

[0025] Specifically, the transverse seam adjustment and extrusion mechanism includes two nuts 6, which are respectively fixedly connected to the top and bottom of the frame 1, and the internal thread sleeve of the nut 6 is provided with a vertical screw rod 7. The transverse plate 2 is rotatably connected to the end of the vertical screw rod 7, and the ends of the two vertical screw rods 7 that are away from each other are fixedly connected with a hand wheel 8. The two vertical screw rods 7 are rotated by the two hand wheels 8. Under the action of the nuts 6, the two vertical screw rods 7 rotationally drive the two transverse plates 2 to approach each other, thereby vertically clamping and fixing the spliced ​​and assembled LED display screen. During the clamping and fixing process, under the extrusion of the two transverse plates 2, the transverse seam between two vertically adjacent LED display screens can be squeezed to make the transverse seam pore smaller.

[0026] Specifically, the two horizontal plates 2 are fixedly connected to the sides close to each other with bearings 15, and the two vertical screws 7 are respectively fixedly sleeved in the inner rings of the corresponding bearings 15, which facilitates the horizontal plate 2 to be rotatably set on the end of the vertical screw 7 so that it does not rotate together with the vertical screw 7.

[0027] Specifically, two vertical holes are provided at the top and bottom of the frame 1, and vertical guide rods 9 are slidably sleeved in the four vertical holes. The four vertical guide rods 9 are respectively fixedly connected to the outer sides of the corresponding horizontal plates 2, so as to guide the horizontal plates 2 and make their movement more stable.

[0028] Specifically, the vertical seam adjustment and extrusion mechanism includes two threaded sleeves 11, which are rotatably connected to the two sides of the frame 1 respectively, and the two threaded sleeves 11 are threaded with a horizontal screw 12. The two vertical plates 3 are respectively fixedly connected to one end of the corresponding horizontal screw 12, and the top and bottom of the threaded sleeve 11 are fixedly connected with a rotating handle 13. When the vertical extrusion is completed, the two threaded sleeves 11 are rotated by rotating the handle 13. Under the guidance limit of the horizontal guide rod 14, the rotation of the threaded sleeve 11 will drive the two horizontal screws 12 and the two vertical plates 3 to approach each other, thereby not only clamping and fixing the spliced ​​and assembled LED display screen on the left and right, but also under the inward extrusion of the left and right vertical plates 3, the vertical seam between the two adjacent LED display screens can be squeezed to make the vertical seam gap smaller.

[0029] Specifically, two bearings 10 are fixedly connected to both sides of the frame 1, and two threaded sleeves 11 are respectively fixedly sleeved in the inner rings of the corresponding bearings 10, which can support the threaded sleeves 11 and make their rotation more stable and smooth.

[0030] Specifically, two transverse guide rods 14 are slidably sleeved on both sides of the frame 1, and the four transverse guide rods 14 are respectively fixedly connected to the outer sides of the corresponding vertical plates 3, so as to guide the vertical plates 3 and make their movement more stable.

[0031] Specifically, two grooves 4 are provided on the sides where the two vertical plates 3 are close to each other, and a slide groove 17 is provided on the inner wall of one side of the groove 4. The height self-adjusting mechanism includes an extrusion spring 16 fixedly connected to the inner wall of the slide groove 17, and the ends of the two extrusion springs 16 that are away from each other are fixedly connected to a slider 18, and one side of the two sliders 18 is fixedly connected to a self-adjusting plate 5. The two self-adjusting plates 5 are respectively slidably mounted in the corresponding grooves 4. Under the extrusion of the two horizontal plates 2, the four self-adjusting plates 5 are pressed to slide inward along the grooves 4 and squeeze the extrusion springs 16, thereby achieving the purpose of self-adjustment, so that the vertical plate 3 and the two self-adjusting plates 5 can always abut between the two horizontal plates 2. When the two horizontal plates 2 move away from each other, under the elastic force of the extrusion spring 16, the two self-adjusting plates 5 can automatically move away from each other, so that the two self-adjusting plates 5 can always abut against the inner side of the horizontal plate 2.

[0032] In the utility model, when in use, the assembled LED display screen is installed in the frame 1, and the two vertical screw rods 7 are rotated by the two hand wheels 8. Under the action of the nut 6, the two vertical screw rods 7 rotationally drive the two horizontal plates 2 to approach each other, so that the assembled LED display screen can be vertically clamped and fixed. In the clamping and fixing process, under the extrusion of the two horizontal plates 2, the horizontal seam between the two vertically adjacent LED display screens can be squeezed to make the horizontal seam smaller. At the same time, under the extrusion of the two horizontal plates 2, the four self-adjusting plates 5 are pressed to slide inward along the groove 4 and squeeze the extrusion spring 16, so as to achieve the purpose of self-adjustment, so that the vertical plate 3 and the two self-adjusting plates 5 can abut between the two horizontal plates 2. When the vertical extrusion is completed, the handle is turned. The hand 13 rotates the two threaded sleeves 11, and under the guide limit of the horizontal guide rod 14, the rotation of the threaded sleeve 11 will drive the two horizontal screws 12 and the two vertical plates 3 to approach each other, thereby not only clamping and fixing the spliced ​​and assembled LED display screen on the left and right, but also, under the inward squeezing of the left and right vertical plates 3, the vertical seam between two adjacent LED display screens can be squeezed to make the vertical seam gap smaller, thereby making the splicing seam gap between adjacent LED display screens smaller, which will not affect the display effect of the later LED display screen. At the same time, when squeezing the horizontal seam, the personnel only need to rotate the two hand wheels 8, and when squeezing the vertical seam, the personnel only need to rotate the two threaded sleeves, thereby making the operation more convenient and efficient, and improving the use effect of the device.
