Technical Field
[0001] This utility model relates to the field of LED screen installation technology, specifically to an LED screen mounting frame. Background Technology
[0002] An LED display screen is a flat panel display composed of small LED module panels used to display various information such as text, images, video, and recorded signals. When an LED screen is installed on an indoor wall, a frame is required to protect it. The frame facilitates the fixing of the LED screen to the wall bracket. Therefore, the mounting frame has two basic functions: fixing the LED screen and fixing itself to the wall or bracket. A common method of fixing an LED screen is to divide the mounting frame into two detachable parts, insert the LED screen, and then fix the mounting frame itself. After fixing, it is then installed on the wall bracket. For aesthetic reasons, the disassembly and assembly parts are usually located on the side facing the wall. When replacing a damaged LED screen, the mounting frame must be removed from the wall bracket, and then the mounting frame must be disassembled again to replace the LED screen, which is not a simple or quick operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1-6 This utility model provides a technical solution: an LED screen mounting frame, including a front panel 2 and a rear panel 3, the front panel 2 and the rear panel 3 are connected by a snap-fit assembly 7, and the LED display screen 1 is installed between the front panel 2 and the rear panel 3.
[0022] The snap-fit assembly 7 includes a through groove 701 and an insert plate 702. The through groove 701 is formed in the top and bottom of the front panel 2 of the mounting frame. The insert plate 702 is fixedly installed on the front of the rear panel 3 of the mounting frame and is inserted into the through groove 701. An L-shaped locking plate 703 is slidably arranged in the through groove 701. The end of the L-shaped locking plate 703 facing the insert plate 702 is inserted into the groove on the insert plate 702. A second spring 709 is fixedly installed on the side of the L-shaped locking plate 703 away from the insert plate 702. A first stop plate 704 is fixedly installed in the through groove 701. A first spring 708 is fixedly installed on the outer wall of the side of the first stop plate 704 facing away from the insert plate 702. A flip plate 705 is rotatably arranged on the inner wall of the through groove 701. A connecting shaft 706 is fixedly installed at the center. The end of the connecting shaft 706 is rotatably embedded into the inner wall of the through groove 701. Spring 1 708 and spring 2 709 are both fixedly connected to the flip plate 705, and spring 1 708 and spring 2 709 are located at the front and rear of the connecting shaft 706, respectively. A stop plate 2 707 is fixedly installed on the inner wall of the through groove 701. The stop plate 2 707 is located below the flip plate 705 and in front of the connecting shaft 706. Spring 1 708 and spring 2 709 have the same specifications, and the number of spring 1 708 is twice that of spring 2 709. The front panel 2 and rear panel 3 of the front and rear mounting frames are used to fix the LED display screen 1 in a way that allows for the LED display screen 1 to be... For secure mounting, use the snap-fit assembly 7 to fix the front panel 2 and rear panel 3 of the mounting frame together. Before the front panel 2 and rear panel 3 are closed, you can use your fingers to lift the front half of the flip plate 705, causing it to rotate. The rotation of the flip plate 705 compresses the first spring 708 and the second tension spring 709, causing the second spring 709 to pull the L-shaped clamping plate 703 towards the flip plate 705. At this time, you can insert the insert plate 702 on the rear panel 3 into the through slot 701. After pressing the front panel 2 and rear panel 3 firmly, release the flip plate 705. At this time, the first spring 708 pushes the flip plate 705 back to its original position, causing the second spring 709 to return to its original position and push the L-shaped clamping plate 703 towards the insert plate 702. The L-shaped card plate 703 is moved so that its top end is inserted into the groove on the insert plate 702, thus completing the installation. The installation process is simple and quick. When the LED display screen 1 needs to be replaced, simply lift the front half of the flip plate 705 again, and then pull the front panel 2 of the mounting frame and the rear panel 3 of the mounting frame apart. The second stop plate 707 is set to restrict the rotation of the flip plate 705, so that the flip plate 705 can only flip up the front half. The different numbers of springs 1 708 and spring 2 709 ensure that spring 1 708 presses the flip plate 705 tightly on the second stop plate 707, so that the flip plate 705 lifts up the second spring 709 and then compresses the second spring 709, which in turn makes the second spring 709 push the L-shaped card plate 703 toward the insert plate 702.
[0023] The front of the LED display screen 1 is covered with a front sealing strip 5, and the back of the LED display screen 1 is covered with a rear sealing strip 6. The front sealing strip 5 and the rear sealing strip 6 are pressed tightly onto the LED display screen 1 by the front panel 2 and the rear panel 3 of the mounting frame, respectively. The front sealing strip 5 and the rear sealing strip 6 are set to prevent the rigid front panel 2 and the rear panel 3 of the mounting frame from pressing directly onto the LED display screen 1.
[0024] An integrated card plate 4 is provided on the back of the rear panel 3 of the mounting frame. A signal line 8 is connected to the back of the LED display screen 1. The signal line 8 passes through the rear sealing strip 6 and then extends out from the integrated card plate 4. The integrated card plate 4 is used to clip the main body of the mounting frame, which consists of the front panel 2 and the rear panel 3 of the mounting frame, onto the wall bracket. The signal line 8 is used to connect the LED display screen 1 to the external controller and power supply.
[0025] A wire harness sleeve 9 is fixedly installed at the part of the integrated card plate 4 through which the signal line 8 passes. The signal line 8 passes through the wire harness sleeve 9. A barbed card plate 11 is fixedly installed on the back of the integrated card plate 4. Four barbed card plates 11 are provided. The barbed card plates 11 can help the integrated card plate 4 to be clamped onto the wall bracket. The wire harness sleeve 9 can prevent the signal line 8 from rubbing against the inner wall of the integrated card plate 4.
[0026] The back of the mounting frame rear panel 3 is fixedly installed with internal threaded posts 10. There are four internal threaded posts 10, which are respectively located near the four corners of the mounting frame rear panel 3. The internal threaded posts 10 are used to fix the mounting frame rear panel 3 to the wall bracket by bolt fixing.
[0027] Positioning posts 12 are fixedly installed at the four corners of the back of the front panel 2 of the mounting frame. The positioning posts 12 are inserted into the positioning grooves on the front of the rear panel 3 of the mounting frame. When the front panel 2 and the rear panel 3 of the mounting frame are closed, the positioning posts 12 play a positioning role. After the front panel 2 and the rear panel 3 of the mounting frame are closed, the positioning posts 12 can also serve as a force transmission structure, making the installation of the front panel 2 and the rear panel 3 of the mounting frame more stable.
[0028] Working principle: In use, place the LED display screen 1 onto the rear sealing strip 6 inside the rear panel 3 of the mounting frame. Before insertion, pass the signal cable 8 of the LED display screen 1 through the cable harness sleeve 9. Then, align the positioning post 12 on the back of the front panel 2 of the mounting frame with the positioning groove on the rear panel 3 of the mounting frame and insert it. During insertion, use your finger to push up the front half of the flip plate 705, causing the flip plate 705 to rotate. The rotation of the flip plate 705 compresses the first spring 708 and the second tension spring 709, causing the second spring 709 to pull the L-shaped clamping plate 703 towards the flip plate 705. At this time, the insert plate 702 on the rear panel 3 of the mounting frame can be inserted into the through groove 701. Inside, after pressing firmly the front panel 2 and rear panel 3 of the mounting frame, release the flip plate 705. At this time, spring 1 708 pushes the flip plate 705 to reset, causing spring 2 709 to reset and push the L-shaped card plate 703 towards the insertion plate 702, so that the top of the L-shaped card plate 703 is inserted into the groove on the insertion plate 702, thus completing the installation. Then, fix the rear panel 3 of the mounting frame to the wall bracket. When the LED display screen 1 needs to be replaced, simply lift the front half of the flip plate 705 again to separate the L-shaped card plate 703 from the insertion plate 702, and then pull the front panel 2 and rear panel 3 of the mounting frame apart. The operation is simple and quick.
[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
