[0002] As the core display component of modern electronic devices, the installation stability of LCDs directly affects the user experience and device lifespan. The screen mounting frame, as a key structure for fixing the screen, plays an important role in the assembly and maintenance of electronic devices.

[0003] Currently, most mainstream LCD monitor screen mounting frames on the market use screw fastening or a single slot structure. While screw fastening mounting frames can achieve stable fixation, the installation process requires tools such as screwdrivers, which is cumbersome and time-consuming, especially in mass production scenarios, which seriously affects assembly efficiency. At the same time, after long-term use, the screws are prone to loosening due to vibration, resulting in an increased gap between the screen and the mounting frame. To address these issues, we have developed an LCD monitor screen mounting frame that solves the above problems. Utility Model Content

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved screen mounting frame for a liquid crystal display. The technical solution of this utility model is as follows:

[0024] like Figure 1 - Figure 6As shown, a screen mounting frame for a liquid crystal display includes a screen body 1. Connecting rods 2 are provided on both the left and right sides of the screen body 1, and support rods 3 are provided on both the top and bottom surfaces of the screen body 1. First slots 4 are formed on the sides of both connecting rods 2. Two symmetrically arranged inserts 5 are fixedly connected to the side walls of both connecting rods 2. An insertion port 6 is formed on the upper surface of each insert 5, and a sliding hole 7 is formed on the rear side wall of each insert 5. A first spring 8 is fixedly connected to the inner wall of each sliding hole 7, and a first spring 8 is slidably connected to the inner wall of each sliding hole 7. There is a notched retaining strip 9, and the side walls of the two support rods 3 are respectively provided with second retaining grooves 10. The left and right side walls of the two support rods 3 are respectively provided with slots 11. The inner wall of each slot 11 is respectively provided with a circular groove 12. The two support rods 3 are respectively provided with two cylindrical sliding grooves 13. The inner wall of each cylindrical sliding groove 13 is respectively provided with a pin 14. The surface of each pin 14 is respectively fixedly fitted with an annular baffle 15. The surface of each pin 14 is respectively fitted with a second spring 16. One end of each pin 14 is respectively fixedly connected with a pull ring 17.

[0025] Furthermore, two symmetrically arranged strip grooves 18 are respectively opened on the rear side walls of the two support rods 3, and two symmetrically arranged limiting grooves 19 are respectively opened in the inner walls of the two support rods 3. A slide rod 20 is slidably connected to the inner wall of each strip groove 18, and a square baffle 21 is fixedly connected to the side wall of each slide rod 20. A third spring 22 is fixedly connected to the inner wall of each limiting groove 19. The third spring 22 can buffer and limit the sliding of the slide rod 20 through the square baffle 21, effectively preventing the slide rod 20 from sliding excessively or getting stuck, and improving the smoothness of structural adjustment and the stability of use.

[0026] Furthermore, the width of each first slot 4 and second slot 10 is equal to the thickness of the screen body 1, each plug 5 is matched with the slot 11, and each socket 6 is connected to the lower surface of each plug 5. The width of the first slot 4 and the second slot 10 is equal to the thickness of the screen body 1, the plug 5 is matched with the slot 11 and the socket 6 is connected to the lower surface of the plug 5. This ensures that the screen body 1 can be accurately inserted into the slot for stable installation, and also ensures that the screen and the support rod 3 are firmly connected after installation through the adaptation of the plug 5 and the slot 11 and the design of the socket 6.

[0027] Furthermore, one end of each pin 14 penetrates the inner wall of the cylindrical slide groove 13 and extends to the surface of the support rod 3, and the other end of each pin 14 penetrates the inner wall of the cylindrical slide groove 13 and extends into the slot 11. The other end of each cylindrical slide groove 13 matches the inner wall of the circular groove 12. Each pull ring 17 is located on the outside of the support rod 3. Each annular baffle 15 is located on the inner wall of each cylindrical slide groove 13 and is slidably connected to the inner wall of the cylindrical slide groove 13. One end of each second spring 16 is fixedly connected to the inner wall of each cylindrical slide groove 13, and the other end of each second spring 16 is fixedly connected to one end of multiple annular baffles 15. The extension and retraction of the pin 14 can be easily controlled by the pull ring 17. The second spring 16, in conjunction with the annular baffle 15, enables the pin 14 to automatically reset and tightly engage with the corresponding circular groove 12 position, realizing quick assembly and disassembly between components. The stable engagement of the pin 14 effectively prevents loosening of the connection and greatly improves the efficiency of assembly and maintenance.

[0028] Furthermore, each strip groove 18 is connected to the inner wall of each slot 11, each limiting groove 19 is connected to the inner wall of each pull ring 17, each square baffle 21 is slidably connected to the inner wall of each limiting groove 19, the other end of each third spring 22 is fixedly connected to the side wall of each square baffle 21, and the snap-fit ​​end of each notched corner clip 9 is matched with each strip groove 18. The strip groove 18 is connected to the slot 11, and the limiting groove 19 is connected to the pull ring 17. With the sliding of the square baffle 21 in the limiting groove 19 and the elastic force of the third spring 22, the smooth linkage of each component is ensured. The matching design of the notched corner clip 9 and the strip groove 18 enables the notched corner clip 9 to be accurately snapped into the strip groove 18 to achieve stable positioning, which not only improves the overall snap-fit ​​reliability of the structure, but also enhances the flexibility of the adjustment process.

[0029] Working principle: During installation and fixing, the edge of the screen body 1 is first inserted into the first slot 4 of the connecting rod 2 and the second slot 10 of the support rod 3 to form a preliminary limit. Then, the insert 5 is inserted into the slot 11 of the support rod 3. During the insertion of the insert 5, the notched corner retaining strip 9 is squeezed, causing the first spring 8 to contract. When the notched corner retaining strip 9 is aligned with the strip-shaped slide 18, the first spring 8 returns to its original position and pushes the notched corner retaining strip 9 into the strip-shaped slide 18, completing the preliminary positioning. At the same time, the pin 14 passes through the insertion port 6 and is embedded in the circular groove 12 under the elastic force of the second spring 16. The annular baffle 15 restricts the excessive movement of the pin 14, realizing the rigid fixation of the connecting rod 2 and the support rod 3. The third spring 22 will push the square baffle 21, causing the slide bar 20 to press tightly against the side wall of the notched corner retainer 9, further enhancing the stability of the overall connection. When disassembly is required, first pull the pull ring 17 to drive the pin 14 to compress the second spring 16, causing the pin 14 to disengage from the round groove 12 and the socket 6, releasing the restriction on the plug 5. Then push the slide bar 20 to compress the third spring 22, and the square baffle 21 slides along the limiting groove 19. The slide bar 20 then pushes the notched corner retainer 9 to compress the first spring 8 and exit the strip groove 18. At this time, the plug 5 can be pulled out from the slot 11, separating the connecting rod 2 and the support rod 3. Finally, the screen body 1 can be removed from the slot to complete the disassembly.
