Description

Technical Field

[0001] This utility model relates to the field of LED display screen bracket technology, specifically to a long-life LED display screen plastic bracket. Background Technology

[0002] LED displays are flat panel displays composed of small LED module panels used to display various information such as text, images, and videos. LED electronic displays integrate microelectronics technology, computer technology, and information processing, and have advantages such as bright colors, wide dynamic range, high brightness, long lifespan, and stable and reliable operation. LED displays are widely used in commercial media, cultural performance markets, sports venues, information dissemination, news releases, securities trading, etc., and can meet the needs of different environments.

[0003] Chinese patent CN215411021U discloses an LED display screen bracket, including a display screen body. The rear of the display screen body has an installation mechanism, which includes an installation plate, a fixing column, a fixing rod, a first compression spring, and a movable rod. The rear of the installation mechanism also has an adjustment mechanism, which includes a support column, a sliding sleeve, a limiting rod, a second compression spring, and a connecting plate. The bottom surface of the adjustment mechanism has a base. The installation plate appears symmetrically, and a fixing block is fixedly installed on the rear wall of the installation plate. This application facilitates quick installation of the LED display screen through its installation mechanism, further facilitating disassembly and maintenance by operators. The adjustment mechanism is used to adjust the height of the LED display screen to meet user needs and improve the overall practicality of the bracket. However, the aforementioned patent relies solely on the support column for support. Given the weight of the display screen, the support column is prone to instability, and a single support column is susceptible to deformation after prolonged support of heavy objects, reducing its lifespan. Therefore, we propose a plastic LED display screen bracket with a longer lifespan. Utility Model Content

[0004] The purpose of this utility model is to provide a long-life LED display plastic bracket to solve the problems mentioned in the background art, which are that when the display screen is heavy, the support column is unstable and the support column is prone to deformation after supporting heavy objects for a long time, thus reducing the service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a long-life LED display plastic bracket, comprising a base plate, a support column, a placement frame, a support mechanism, and a fixing mechanism. The support column is fixed to the top center of the base plate, the placement frame is fixed to the top of the support column, the support mechanism is connected to the outside of the support column, and the fixing mechanism is connected to the outside of the placement frame. The support mechanism includes a connecting ring that slides on the outside of the support column. A fixing seat is fixed to the center of the four outer walls of the connecting ring. A support rod rotates inside the fixing seat. An mounting seat is fixed to the top of the inner side of the support rod. A connecting seat is fixed to the bottom of the four outer walls of the support column. A connecting rod rotates inside the connecting seat. Insertion holes are evenly distributed on one side of the support column. An L-shaped plate is fixed to the top center of one side of the connecting ring. An insertion rod slides through the center of one side of the L-shaped plate. A pull plate is fixed to one end of the insertion rod, and a connecting spring is fixed to one side of the pull plate.

[0006] As a further description of the above technical solution:

[0007] One end of the connecting rod rotates inside the mounting base.

[0008] As a further description of the above technical solution:

[0009] The connecting spring is sleeved on the outside of the insert rod, and one end of the connecting spring is fixed to one side of the L-shaped plate.

[0010] As a further description of the above technical solution:

[0011] The fixing mechanism includes fixing plates symmetrically fixed to the back of the placement rack. A bidirectional screw is rotatably driven through the middle of the opposite sides of the two fixing plates. Turntables are fixed at both ends of the bidirectional screw. Limiting rods are symmetrically fixed to the opposite sides of the two fixing plates. A movable plate is symmetrically threaded to the outer side of the bidirectional screw. A connecting block is fixed to the middle of one side of the movable plate. A clamping plate is fixed to one side of the connecting block. A through groove is opened through the middle of one side of the placement rack.

[0012] As a further description of the above technical solution:

[0013] The movable plate slides symmetrically on the outer wall of the limiting rod, and a rubber pad is fixed on one side of the clamping plate.

[0014] As a further description of the above technical solution:

[0015] The connecting block is located inside the through groove, and the outer side of the connecting block is in contact with the inner side of the through groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This long-life LED display plastic bracket, by pulling the pull plate, moves the insertion rod out of the insertion hole, simultaneously stretching the connecting spring. Then, the connecting ring descends, causing the fixing base to descend as well, deflecting the support rod and unfolding it. Simultaneously, the connecting rod deflects, bringing the support rod into contact with the ground. The insertion rod then aligns with the insertion hole. The resetting of the connecting spring allows the insertion rod to be embedded in the insertion hole, securing the connecting ring. The cooperation between the support rod and the support column makes the support more stable, increases the bottom support area, and distributes the weight across the support rod, preventing it from acting entirely on the support column, thus preventing deformation and extending its service life.

[0018] 2. This long-life LED display plastic bracket, by placing the display on the mounting rack, rotating the turntable drives the bidirectional screw to rotate, and using the limiting rod to limit the moving plate. When the bidirectional screw rotates, the moving plate moves closer to each other outside the limiting rod, causing the clamping plates to move closer to each other, clamping the two sides of the display, thereby fixing the display and making the display stable. At the same time, it is easy to fix the display of different lengths, improving the applicability of the device. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] This utility model provides a long-life LED display plastic bracket, which makes the support more stable, increases the bottom support area, and uses support rods to distribute the weight, avoiding the entire force acting on the support column, preventing the support column from deforming, and extending the service life. Please refer to [link / reference]. Figure 1-4 It includes a base plate 100, a support column 200, a placement rack 300, a support mechanism 400, and a fixing mechanism 500;

[0028] Please refer to it again. Figure 1 The base plate 100 is used to install the support column 200, the placement rack 300, the support mechanism 400 and the fixing mechanism 500;

[0029] Please refer to it again. Figure 1The support column 200 is fixed to the top center of the base plate 100 and is used to install the placement rack 300. The placement rack 300 is fixed to the top of the support column 200 and is used to install the fixing mechanism 500. The support mechanism 400 is connected to the outside of the support column 200 and the fixing mechanism 500 is connected to the outside of the placement rack 300.

[0030] Please refer to it again. Figure 2 The support mechanism 400 includes a connecting ring 410 that slides on the outside of the support column 200. A fixing seat 420 is fixed in the middle of the four outer walls of the connecting ring 410. A support rod 430 rotates inside the fixing seat 420.

[0031] Please refer to it again. Figure 2 The support rod 430 has a mounting base 431 fixed on the top of its inner side, and the support column 200 has a connecting base 440 fixed on the bottom of its four outer walls. The connecting base 440 has a connecting rod 450 rotating inside it, and the support column 200 has evenly spaced insertion holes 460 on one side of its outer side.

[0032] Please refer to it again. Figure 3 An L-shaped plate 470 is fixed to the top center of one side of the connecting ring 410. A rod 480 slides through the middle of one side of the L-shaped plate 470. A pull plate 490 is fixed to one end of the rod 480. A connecting spring 491 is fixed to one side of the pull plate 490.

[0033] In summary, by pulling the pull plate 490, the insertion rod 480 is moved out of the insertion hole 460, and the connecting spring 491 is stretched. Then, the connecting ring 410 descends, causing the fixing seat 420 to descend, which in turn causes the support rod 430 to deflect and unfold. At the same time, the connecting rod 450 deflects, bringing the support rod 430 into contact with the ground. Then, the insertion rod 480 is aligned with the insertion hole 460. By resetting the connecting spring 491, the insertion rod 480 is embedded in the insertion hole 460, fixing the connecting ring 410. Through the cooperation of the support rod 430 and the support column 200, the support is more stable, the bottom support area is increased, and the weight borne by the support rod 430 is distributed, avoiding the entire force acting on the support column 200, preventing deformation of the support column 200, and extending its service life.

[0034] Please refer to it again. Figure 2 One end of the connecting rod 450 rotates inside the mounting base 431.

[0035] Please refer to it again. Figure 3 The connecting spring 491 is sleeved on the outside of the insert rod 480, and one end of the connecting spring 491 is fixed to one side of the L-shaped plate 470.

[0036] Please refer to it again. Figure 4The fixing mechanism 500 includes fixing plates 510 symmetrically fixed to the back side of the placement rack 300. A bidirectional screw 520 is rotatably driven through the middle of the opposite sides of the two fixing plates 510. Turntables 521 are fixed at both ends of the bidirectional screw 520. Limiting rods 530 are symmetrically fixed to the opposite sides of the two fixing plates 510. A movable plate 540 is symmetrically screwed to the outside of the bidirectional screw 520 by threads. A connecting block 550 is fixed to the middle of one side of the movable plate 540. A clamping plate 560 is fixed to one side of the connecting block 550. A through groove 570 is opened through the middle of one side of the placement rack 300.

[0037] Please refer to it again. Figure 4 The movable plate 540 slides symmetrically on the outer wall of the limiting rod 530, and a rubber pad is fixed on one side of the clamping plate 560.

[0038] Please refer to it again. Figure 4 The connecting block 550 is located inside the through groove 570, and the outer side of the connecting block 550 is in contact with the inner side of the through groove 570.

[0039] In summary, by placing the display screen on the mounting rack 300 and rotating the turntable 521, the bidirectional screw 520 is rotated. The limiting rod 530 limits the moving plate 540. When the bidirectional screw 520 rotates, the moving plate 540 moves closer to each other outside the limiting rod 530, causing the clamping plates 560 to move closer to each other, clamping both sides of the display screen and fixing it. This ensures stable placement of the display screen and facilitates fixing display screens of different lengths, improving the applicability of the device.

[0040] In practical use, those skilled in the art first pull the pull plate 490, causing the insertion rod 480 to move out of the insertion hole 460. Simultaneously, the connecting spring 491 is stretched. Then, the connecting ring 410 descends, causing the fixing base 420 to descend, causing the support rod 430 to deflect and unfold. Simultaneously, the connecting rod 450 deflects, bringing the support rod 430 into contact with the ground. Then, the insertion rod 480 is aligned with the insertion hole 460. The resetting of the connecting spring 491 causes the insertion rod 480 to be embedded in the insertion hole. In hole 460, connecting ring 410 is fixed. Through the cooperation of support rod 430 and support column 200, the support is more stable and the bottom support area is increased. The display screen is placed on the placement rack 300. Rotate turntable 521 to drive bidirectional screw 520 to rotate. Limiting rod 530 is used to limit moving plate 540. When bidirectional screw 520 rotates, moving plate 540 moves closer to each other outside of limiting rod 530, driving clamping plate 560 to move closer to each other, clamping both sides of the display screen, thereby fixing the display screen.
