[0033] [[ID=~14]]Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0035] In order to solve the problem that the fixed structure connection and fixing method of the hanging display screen in the prior art are not easy to quickly disassemble, which is not conducive to the maintenance and customization application of the display screen, the present invention proposes a fixed structure for the display screen guide rail 3. Refer to Figures 1 to 11, the fixed structure of the display rail 3 of the present utility model includes: a display frame 2; a rail 3 provided with a locking portion 34; a connecting mechanism 4 provided on the display frame 2, the connecting mechanism 4 includes an elastic locking member 44 and a pressing member 43, and the pressing member 43 is slidably connected to the elastic locking member 44; wherein, when the pressing member 43 slides relative to the elastic locking member 44, the elastic locking member 44 pops out in a direction away from the pressing member 43 to cooperate with the locking portion 34 to lock the display frame 2 and the rail 3, or, the elastic locking member 44 rebounds in a direction close to the pressing member 43 to disengage from the locking portion 34 to disassemble the display frame 2. The present utility model designs a rail 3 with a locking portion 34, and designs a connecting mechanism 4 on the display frame 2. The connecting mechanism 4 includes a pressing member 43 that can slide relative to each other and an elastic locking member 44 that can achieve popping and rebounding actions as it slides relative to the pressing member 43. To Figure 3 and Figure 5For example, a hanging part 31 is provided at the top of the guide rail 3. The hanging part 31 is used to be installed and fixed to the ceiling structure member to fix the guide rail 3. There is an upwardly concave installation groove 35 below the guide rail 3. On both sides of the bottom of the installation groove 35, there are a first power supply part 321 and a second power supply part 331. The first power supply part 321 and the second power supply part 331 are recessed towards the left and right sides respectively, and a first electric rail 322 and a second electric rail 332 are respectively provided therein. On the left and right sides of the opening of the installation groove 35, there are locking parts 34, and support convex parts are provided at positions of the locking parts 34 close to the opening of the installation groove 35. The double-sided display screen 1 includes a screen 12 and a screen frame 11 wrapped around the periphery of the screen 12. A docking port (not shown in the figure) for connecting with the double-sided display screen 1 for data and power transmission is provided inside the outer shell 21 of the display screen frame 2. There are locking screws inside the outer shell 21. The screen frame 11 and the display screen frame 2 are stably connected into a whole through the locking screws. A power supply assembly 23 is provided in the upper region inside the outer shell 21. The power supply assembly 23 includes a power supply board 231 for providing a power supply environment required for the operation of the double-sided display screen 1. The power supply board 231 is fixed to the outer shell 21 through power supply board fastening screws. The power supply board 231 is connected through wires and power supply elastic pieces 233. The power supply elastic pieces 233 are respectively arranged on the left and right sides of the outer shell 21. When the display screen frame 2 is installed in the installation groove 35, the power supply elastic pieces 233 arranged on the left and right sides of the outer shell 21 are elastically abutted against the first electric rail 322 and the second electric rail 332 respectively, so that the double-sided display screen 1 can work. In order to make it easy to disassemble the display screen frame 2 from the guide rail 3 or move it conveniently on the guide rail 3 to meet the use requirements, a connection mechanism 4 is provided in the outer shell 21. The connection mechanism 4 includes a pressing part 43 and an elastic locking part 44. Through the relative sliding between the elastic locking part 44 and the pressing part 43, the elastic locking part 44 can move on the outer shell 21, so that the elastic locking part 44 can pop out and rebound. The elastic locking part 44 pops out in the direction away from the pressing part 43 and tightly combines with the locking part 34 on the guide rail 3, so as to fix the display screen frame 2 and the guide rail 3 and ensure the stable connection between the display screen and the guide rail 3. On the contrary, the elastic locking part 44 rebounds in the direction close to the pressing part 43 and automatically disengages from the locking part 34, allowing the user to easily disassemble the display screen frame 2. Through the design of the elastic locking part 44 and the pressing part 43, the user can easily achieve quick disassembly or installation by manipulating the pressing part 43, significantly improving the maintenance efficiency. Compared with traditional bolts or plastic buckles, this embodiment also enables the user to perform installation or disassembly without additional tools, reducing the complexity of the operation.

[0036] Compared with the prior art, in the technical solution of the present utility model, by providing a movable elastic locking member 44 and a pressing member 43 on the display screen frame 2, providing an avoidance portion 432 on the pressing member 43, and providing a locking portion 34 on the guide rail 3, the relative position or shape of the locking member can be changed by the movement of the pressing member 43, so that the elastic locking member 44 pops out or rebounds, thereby cooperating with the locking portion 34 to complete the locking and detachment between the guide rail 3 and the display screen frame 2, realizing the quick disassembly of the fixed structure of the display screen guide rail 3, and facilitating the maintenance and customization application of the display screen.

[0037] In one embodiment, referring to Figure 6 and Figure 8 , a path portion 431 and an avoidance portion 432 are provided on the side surface of the pressing member 43. The avoidance portion 432 is provided in the path portion 431. The avoidance portion 432 is recessed from the side surface of the pressing member 43 into the pressing member 43. The elastic locking member 44 is provided with a second convex portion 4421. The second convex portion 4421 slides on the path portion 431. The avoidance portion 432 cooperates with the second convex portion 4421 to pop out or rebound the elastic locking member 44. Taking Figure 8 as an example, the path portion 431 is a side surface area of the pressing member 43, allowing the second convex portion 4421 of the elastic locking member 44 to slide on this part. The avoidance portion 432 is located within the path portion 431 and is a portion recessed into the pressing member 43. The bottom surface of the recess is a curved surface, facilitating the second convex portion 4421 to return to the path portion 431 again. The avoidance portion 432 has the function of cooperating with the second convex portion 4421. The second convex portion 4421 can slide on the path portion 431 to realize the interaction with the avoidance portion 432. When the user operates the pressing member 43, the second convex portion 4421 moves on the path portion 431 towards the avoidance portion 432 and finally falls into the avoidance portion 432, and the elastic locking member 44 rebounds, disengaging from the locking portion 34, so that the display screen frame 2 and the guide rail 3 can be detached or moved. On the contrary, when the user does not operate the pressing member 43, the second convex portion 4421 remains on the path portion 431. At this time, the elastic locking member 44 remains in the popped state and is tightly combined with the locking portion 34 on the guide rail 3, and the display screen frame 2 and the guide rail 3 are connected and fixed. The provision of the path portion 431 and the avoidance portion 432 can guide the movement of the elastic locking member 44, prevent accidental movement, reduce the risk of failure caused by improper operation, and ensure the smoothness and reliability during the operation.

[0038] In one embodiment, referring to Figure 3 , Figure 4 , Figure 6 , Figure 9 and Figure 11, the elastic locking member 44 is further provided with a first convex portion 4411, and the locking portion 34 is provided with a supporting convex edge 341. The first convex portion 4411 cooperates with the supporting convex edge 341 to lock the display screen frame 2 and the guide rail 3. In order to further enhance the bonding strength between the elastic locking member 44 and the locking portion 34 on the guide rail 3, the first convex portion 4411 is provided on the elastic locking member 44. The setting of the first convex portion 4411 enables the elastic locking member 44 to extend longer structural bodies to the left and right sides in the ejected state, so as to facilitate stable engagement with the supporting convex edge 341 provided on the locking portion 34, making the stability better. At the same time, since the overlapping relationship between the first convex portion 4411 and the supporting convex edge 341 is multi-point support, compared with the surface contact between the elastic locking member 44 and the locking portion 34 without the first convex portion 4411, the user's feeling when grasping the display screen frame 2 for installation without normal engagement will be different from that in normal engagement. The user can more intuitively feel the feedback of locking and unlocking during use, thus playing a reminder role for the user to correctly install the display screen frame 2 and the guide rail 3. Further, the upper part of the first convex portion 4411 is an inclined surface, which is used to guide the elastic locking member 44 to retract when the display screen frame 2 is installed through the edge of the track opening, preventing jamming with the edge of the track opening and causing damage to the elastic locking member 44 due to a large impact force. The lower part of the first convex portion 4411 is a right-angle edge, which enhances the overlapping relationship between the first convex portion 4411 and the supporting convex edge 341, thereby making the engagement between the display screen frame 2 and the guide rail 3 more stable.

[0039] In one embodiment, referring to Figure 1 , Figure 3 , Figure 6 and Figure 7, at both ends of the display screen frame 2 along the length direction of the guide rail 3, there are button slots 25. The button slots 25 are recessed towards the inside of the display screen frame 2. There is a reset elastic member 41 between the pressing member 43 and the bottom of the button slot 25, and the pressing member 43 is slidably arranged in the button slot 25. The recessed button slots 25 provided at both ends of the display screen frame 2 along the length direction of the guide rail 3 enable the pressing member 43 to slide inside. During actual use, the button slots 25 are correspondingly set according to the shape of the pressing member 43, so that the button slots 25 can effectively prevent the up-and-down shaking of the pressing member 43, ensure that the pressing member 43 can slide stably, reduce the inconvenience of operation caused by deviation, and improve the stability and reliability of the entire locking structure. The reset elastic member 41 is located between the pressing member 43 and the bottom of the button slot 25. The reset elastic member 41 can be a spring piece or a spring. After the user performs a pressing operation, it ensures that the pressing member 43 can automatically return to the initial position after being released. The setting of the reset elastic member 41 ensures that the pressing member 43 can quickly return to its original position after use, reducing the risk of misoperation during the operation process. At the same time, a reset elastic member embedding groove 251 for preventing the reset elastic member 41 from slipping is provided at the connection between the outer shell 21 and the reset elastic member 41, which is used to prevent the reset elastic member 41 from slipping and weakening its ability to reset the pressing member 43 itself. In this embodiment, the user only needs to press the pressing member 43 to enable the elastic locking member 44 to automatically disengage from the locking portion 34, and the reset elastic member 41 will ensure that the pressing member 43 automatically rebounds after being released, optimizing the ergonomics of the fixed structure of the display screen guide rail 3 and facilitating user operation.

[0040] In one embodiment, referring to Figure 6 and Figure 7 , a spring embedding hole 26 is provided on the side surface of the display screen frame 2. The spring embedding hole 26 is communicated with the button slot 25, and the elastic locking member 44 is arranged in the spring embedding hole 26. In order to enable the elastic locking member 44 to be firmly fixed and reduce the risk of accidental loosening caused by external forces, the spring embedding hole 26 is provided to install the elastic locking member 44. The spring embedding holes 26 are respectively arranged on the left and right sides of the outer shell 21 and are communicated with the button slot 25 to ensure the normal movement between the elastic locking member 44 and the pressing member 43. The spring embedding hole 26 provides a more stable environment, making the elastic locking member 44 not easily displaced during the operation process and enhancing the reliability of the entire fixed structure. At the same time, since the spring embedding hole 26 is communicated with the inside and outside of the display screen frame 2, it is more convenient to replace and maintain the elastic locking member 44 and the pressing member 43, improving the convenience of maintenance.

[0041] In one embodiment, referring to Figure 6 , Figure 7Figure 9 to Figure 11 The elastic locking member 44 includes a first spring 441, a second spring 442 and a third spring 443. The first spring 441 and the second spring 442 are elastically connected, and the second spring 442 and the third spring 443 are elastically connected. The third spring 443 is fixed to the spring hole 26. The first spring 441 is close to the supporting flange 341, and the second spring 442 is close to the pressing member 43. In order to further enhance the function of the elastic locking member 44, a Figures 9 to 11 The elastic locking member 44 in the elastic locking member 44. The elastic locking member 44 is a metal sheet metal part. Through sheet metal processing, the first spring 441 and the second spring 442 are cold-pressed and bent. The two springs are bent in opposite directions, leaving a gap in the middle to provide space for the first spring 441 to move when the bend is elastically deformed. The second spring 442 and the third spring 443 are also cold-pressed and bent 90 degrees to form a connecting body. The third spring 443 is fixed in the spring hole 26, providing a stable fixing foundation so that the elastic locking member 44 is not easy to loosen. The first spring 441 is close to the supporting flange 341, and the first spring 441 can directly abut the supporting flange 341 to complete the locking. The second spring 442 is close to the pressing member 43 to ensure that when the pressing member 43 is pressed and released, it can provide an effective response and necessary elastic support for the first spring 441. Through the elastic connection of the first, second, and third springs 441, 442, 443, the elastic locking member 44 can flexibly respond when the pressing member 43 is pressed and quickly rebound when released, enhancing locking reliability. Furthermore, the design of this embodiment enables the elastic locking member 44 to more evenly distribute pressure across the various springs when subjected to force, reducing localized stress concentration and improving overall durability. Furthermore, because the elastic locking member 44 in this embodiment can be directly manufactured through cold pressing of sheet metal, overall production costs are reduced.

[0042] Further, refer to Figures 9 to 11 , support folds 4431 are provided on both sides of the third spring 443, and a reinforcement fold 4432 is provided on the top of the third spring 443. Two support folds 4431 are provided on both sides of the third spring 443, which are cold-pressed and bent opposite to each other, and extend a certain length along the length direction of the sheet metal body of the third spring 443. The purpose of providing the support folds 4431 is to ensure that there are more support points between the third spring 443 and the spring hole 26, so as to ensure that the installation of the elastic locking member 44 is more stable. A reinforcement fold 4432 is provided on the top of the third spring 443 by cold-pressing and bending at 90°. The reinforcement fold 4432 is fitted with or embedded in the inner wall of the shell 21, and the maximum elastic force provided by the elastic locking member 44 is further enhanced through the connection with the shell 21, thereby enhancing the structural strength, so that the fixed structure of the display screen guide rail 3 can withstand a larger load.

[0043] In one embodiment, referring to Figures 9 to 11, the first convex portion 4411 is provided on the surface of the first spring piece 441 close to the supporting convex edge 341, and the second convex portion 4421 is provided on the surface of the second spring piece 442 close to the path portion 431. The first convex portion 4411 is provided on the surface of the first spring piece 441 close to the supporting convex edge 341, and its cooperation with the supporting convex edge 341 enhances the stability and supporting force during locking. The second convex portion 4421 is provided on the surface of the second spring piece 442 close to the path portion 431 to ensure effective interaction with the path portion 431 in the locked state, increasing the locking effect and safety. The positional relationship between the first convex portion 4411 and the second convex portion 4421 and the first spring piece 441 and the second spring piece 442 provides additional mechanical support for the display screen holder 2 and the guide rail 3, which helps to maintain the connection state in the case of sudden changes in force, such as a sudden increase, and prevents accidental loosening.

[0044] In one embodiment, referring to Figure 7 and Figure 8 , a limiting member 433 is provided on the pressing member 43, and a limiting stop edge is provided at the notch of the button groove 25. The limiting member 433 cooperates with the limiting stop edge to prevent the pressing member 43 from disengaging from the button groove 25. Limiting members 433 that bend away from the pressing member 43 are provided on the upper and lower sides of the pressing member 43. The reason for setting them on the upper and lower sides is to prevent interference with the sliding between the elastic locking member 44 and the pressing member 43. A limiting stop edge is provided at the notch of the button groove 25, which, together with the limiting members 433 on the upper and lower sides of the pressing member 43, ensures that the pressing member 43 will not accidentally disengage from the button groove 25 during use, enhancing the structural stability. The limiting stop edge forms a physical barrier, enabling the pressing member 43 to always remain within a predetermined track during operation, reducing the risk of damage caused by accidental detachment of the pressing member 43. Further, a resilient portion 434 is also provided between the pressing member 43 and the limiting member 433. The limiting member 433 itself has a certain elasticity. When the pressing member 43 is inserted into the pressing groove, when the pressing member 43 is pushed into the pressing groove, the limiting stop edge will press the limiting member 433 back into the resilient portion 434, enabling the pressing member 43 to more easily enter the pressing groove. After correct installation, the limiting member 433 rebounds and bends away from the pressing member 43 under its own elastic force, thus realizing its function of preventing the pressing member 43 from disengaging from the button groove 25.

[0045] In one embodiment, referring to Figure 6 and Figure 8, a positioning hole 4321 is provided at the bottom of the avoidance portion 432. The second convex portion 4421 can be recessed into the positioning hole 4321. The positioning hole 4321 and the second convex portion 4421 cooperate to limit the pressing member 43. During actual use, it is found that the avoidance portion 432 is recessed in the path portion 431, and in order to facilitate the second convex portion 4421 to return to the path portion 431 again, its bottom surface is designed as a curved surface, which makes it difficult for the user to figure out whether the pressing member 43 is correctly pressed in place so that the second convex portion 4421 is already at the bottom of the avoidance portion 432, and whether the display screen holder 2 has been separated from the guide rail 3, and the use feedback is very poor. In order to enhance the feedback to facilitate the user to make a correct judgment, a positioning hole 4321 is provided at the bottom of the avoidance portion 432. The second convex portion 4421 can partially sink into the positioning hole 4321 and form a stable abutment with the edge of the positioning hole 4321. The movement cooperation relationship between the second convex portion 4421 and the positioning hole 4321 enables the user to feel a clearer feedback when operating the pressing member 43, avoiding misoperation and improving the safety and reliability of use. At the same time, it also enables the pressing member 43 to be effectively limited during the operation process, preventing the pressing member 43 from being overly moved during use.

[0046] The present utility model also provides a display screen, which includes the display screen guide rail 3 fixing structure in the above-mentioned embodiment. Compared with similar products in the prior art, this display screen has better stability and safety, is easy to manufacture, install and maintain, is easier to carry out customized design and large-area promotion. At the same time, since the key parts are metal sheet metal parts, it has lower cost and longer service life.
