Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0032] This utility model provides a snap-fit ​​structure that can be unlocked simply by pressing a button. The connecting piece moves the locking tongue back into the receiving space, allowing the power supply back cover to quickly separate from the main body, greatly improving disassembly and assembly efficiency and reducing maintenance and time costs. In the locked state, the locking tongue, under the continuous action of the first elastic element, tightly adheres to the power supply back cover, forming a stable connection and effectively preventing accidental detachment during use, ensuring the stable operation of the LED display screen. The first elastic element ensures that the locking tongue maintains good elasticity and reset capability during repeated use, extending the service life of the snap-fit ​​structure while reducing wear and damage caused by disassembly and assembly. This snap-fit ​​structure has good versatility and can be widely used in different types of LED display power supply boxes, providing a convenient solution for rapid maintenance in the display screen technology field. Example

[0033] This utility model embodiment provides a snap-fit ​​structure, such as Figures 1 to 6 As shown, it includes: a main body 10, which includes a first opening 110 and a second opening 120, with an accommodating space 130 between the first opening 110 and the second opening 120, the accommodating space 130 being disposed inside the main body 10; a locking assembly 20, which includes a locking tongue 210 and a first elastic member 220, the first elastic member 220 abutting against the locking tongue 210 and applying a force to the locking tongue 210 toward the first opening 110 away from the accommodating space 130; and an unlocking assembly 30, which includes a button 310 and a connector 320, the unlocking assembly 30 being slidably connected to the locking assembly 20 through the connector 320, the button 310 being disposed in the second opening 120.

[0034] like Figure 1 and Figure 2 As shown, more specifically, the direction of the first opening 110 is perpendicular to the direction of the second opening 120.

[0035] This perpendicular arrangement of the first opening 110 and the second opening 120 makes the latching structure more compact, effectively utilizing the limited space inside the power supply box. This design not only reduces the overall size but also makes the power supply box look cleaner, enhancing the product's aesthetics. Since the second opening 120 (usually where the button 310 is located) is perpendicular to the first opening 110 (where the latch 210 operates), users can easily access the button 310 from the side or top without adjusting their hand angle or position, further enhancing ease of operation. The vertical layout allows the latch 210 to more effectively resist forces from different directions, such as vibration and impact, when locked. This stability not only ensures a secure connection of the power supply back cover during normal use but also improves the reliability and durability of the entire LED display system. Because the button 310 is located perpendicular to the direction of the latch 210, the possibility of accidental operation is reduced to some extent. Users need to clearly align and press the button 310 to unlock, reducing the risk of the power supply back cover loosening or falling off due to accidental contact. The snap-fit ​​structure's vertical opening design makes it easier to integrate with other components or systems, while also facilitating standardized production. Manufacturers can produce power boxes of different sizes and specifications based on this design standard to meet the needs of different LED displays, reducing production costs and complexity.

[0036] like Figure 3 and Figure 4 As shown, more specifically, the unlocking component 30 also includes a second elastic element 330, one end of which is connected to the button 310 and the other end is connected to the locking tongue 210.

[0037] Understandably, the addition of the second elastic element 330 provides force feedback for the button 310 during unlocking. When the user presses the button 310, the second elastic element 330 compresses until the required unlocking force is reached, at which point the latch 210 is released. This force feedback mechanism not only enhances the user experience but also allows the user to clearly perceive the success or failure of the unlocking action. After unlocking, the second elastic element 330 naturally unfolds, pushing the button 310 and the connector 320 back to their initial positions, preparing for the next locking. This automatic reset function ensures the stability and reliability of the latch structure, avoiding potential problems caused by parts not returning to their original positions after unlocking. Precise control of the unlocking force can be achieved by adjusting the rigidity and preload of the second elastic element 330. This helps meet the different requirements for unlocking force in different application scenarios, improving the product's adaptability and flexibility. As the medium connecting the button 310 and the latch 210, the second elastic element 330 bears some of the stress and impact during the unlocking process. This helps reduce wear and damage to the latch 210 and button 310 themselves during frequent unlocking, thereby extending the service life of the entire latch structure.

[0038] like Figure 3 and Figure 4 As shown, the latch 210 includes a first slide rail 2110, and the connector 320 is slidably connected to the latch 210 via the first slide rail 2110. More specifically, the first slide rail 2110 passes through the latch 210, and the connector 320 includes a connecting rod 3210, which passes through the first slide rail 2110.

[0039] Understandably, the extension direction of the first slide rail 2110 is from the second opening 120 toward the first opening 110.

[0040] Thus, the first slide rail 2110 provides a precise sliding path for the connecting rod 3210, ensuring that the connector 320 moves smoothly and steadily during unlocking. This precise sliding not only improves operational reliability but also reduces jamming caused by poor sliding or misalignment. The connecting rod 3210 passes through the first slide rail 2110, allowing the user to directly transfer force to the latch 210 when pressing the button 310, achieving efficient force transmission. This reduces force loss and dispersion during transmission, improving unlocking efficiency and response speed. Because the first slide rail 2110 passes through the latch 210 and the connecting rod 3210 also passes through it, the overall layout of the latch structure is more compact. This not only helps reduce the size and weight of the power box but also improves the product's integration and aesthetics. When the latch structure needs replacement or repair, the design of the first slide rail 2110 and the connecting rod 3210 clearly defines the connection relationships between the components, allowing for easy disassembly and assembly of each component, reducing the complexity and difficulty of maintenance.

[0041] Furthermore, the first slide rail 2110 extends from the second opening 120 towards the first opening 110. This design ensures that when the user presses the button 310, it directly acts on the unlocking direction of the latch 210, making the unlocking action more direct and effective. At the same time, this layout conforms to ergonomic principles, improving operational comfort and convenience.

[0042] like Figure 2 and Figure 3 As shown, the main body 10 also includes a third opening 140, which is adapted to the connector 320. This allows the connector 320 to enter and exit the third opening 140. It can be understood that the third opening 140 increases the range of motion of the connector 320, thus allowing for a longer locking tongue 210. More specifically, the main body 10 also includes a guide groove 150, which is adapted to the connector 320.

[0043] Understandably, increasing the range of motion of connector 320 allows for the design of a longer latch 210. A longer latch 210 means greater locking force in the locked state, thus enhancing the stability of the power supply back cover. Simultaneously, greater force is required to overcome this locking force during unlocking, thereby improving security and preventing unauthorized disassembly. The third opening 140 allows connector 320 greater room to move during unlocking, helping to reduce operational difficulties or jamming caused by space constraints. Furthermore, the longer range of motion allows users to adjust the angle and force of pressing button 310 according to actual needs, improving operational flexibility.

[0044] The introduction of the guide groove 150 further optimizes the layout of the snap-fit ​​structure. The guide groove 150 adapts to the connector 320, providing a precise movement trajectory and guidance for the connector 320, ensuring a smooth and stable unlocking process. This design not only improves the compactness and aesthetics of the structure but also enhances the overall stability and reliability. By adjusting the size and shape of the third opening 140 and the guide groove 150, snap-fit ​​structures adapted to different application scenarios can be designed. For example, in situations requiring greater locking force or a longer latch 210, this can be achieved by increasing the size of the third opening 140 and setting a longer guide groove 150. This flexibility makes the snap-fit ​​structure have a wider range of applications and adaptability.

[0045] Although components such as the third opening 140 and guide groove 150 are added, these designs can usually be mass-produced through processes such as injection molding, thereby simplifying the manufacturing process and reducing costs. At the same time, the clear and straightforward mating relationships between the various components also facilitate assembly and debugging.

[0046] Compared with existing technologies, the snap-fit ​​structure provided in this embodiment of the utility model can be unlocked simply by pressing a button. The connecting piece drives the locking tongue back into the accommodating space, allowing the power supply back cover to quickly separate from the main body, greatly improving disassembly and assembly efficiency and reducing maintenance and time costs. In the locked state, the locking tongue is tightly fitted to the power supply back cover under the continuous action of the first elastic element, forming a stable connection and effectively preventing accidental detachment of the power supply back cover during use, ensuring the stable operation of the LED display screen. The first elastic element allows the locking tongue to maintain good elasticity and reset ability during repeated use, extending the service life of the snap-fit ​​structure while reducing wear and damage caused by disassembly and assembly. This snap-fit ​​structure has good versatility and can be widely used in different types of LED display power supply boxes, providing a convenient solution for rapid maintenance in the field of display screen technology. Example

[0047] Based on the same concept, this utility model embodiment also provides a power supply box, including the snap-fit ​​structure 1 of any one of the embodiments in Embodiment 1.

[0048] like Figure 6 As shown, the power supply box of this embodiment can be provided with a latching structure 1 at each end of the power supply box. By providing latching structures 1 at both ends of the power supply box, double-point locking is achieved. This double-point locking method can more effectively resist forces and vibrations from different directions, thereby enhancing the stability between the power supply box and the LED display screen or other mounting components.

[0049] The dual-snap structure 1 allows users to operate simultaneously on both ends of the power supply box during disassembly and assembly. This parallel operation significantly shortens disassembly and assembly time and improves work efficiency. This is especially beneficial in scenarios requiring frequent maintenance and replacement of the power supply box, reducing maintenance and time costs. The dual-snap structure 1 not only improves disassembly and assembly efficiency but also makes the operation smoother and more intuitive. Users do not need to painstakingly search for and operate individual snaps; they can simply press buttons 310 simultaneously on both ends of the power supply box to complete the unlocking process. This design reduces operational difficulty and complexity, enhancing the user experience. The snap structure 1 at both ends of the power supply box also enhances security to some extent. Since both snaps need to be unlocked simultaneously to open the power supply box, this reduces the risk of unauthorized personnel disassembling the power supply box. Furthermore, during transportation or movement, the dual-snap structure 1 better maintains the closed state of the power supply box, preventing internal components from loosening or being damaged due to vibration. Although this embodiment uses a snap structure 1 at both ends of the power supply box as an example, this design concept is also applicable to power supply boxes of different sizes and shapes. By adjusting the layout and size of the snap-fit ​​structure 1, it can be flexibly adapted to the needs of various power boxes, achieving the goal of quick assembly and disassembly and a stable connection. Example

[0050] Based on the same concept, this utility model embodiment also provides an LED display screen, including a power supply box, with a buckle structure 1 of any one of the embodiments 1 provided on both sides of the power supply box.

[0051] LED displays are typically installed in various complex environments, such as outdoor billboards and stage backdrops. In these scenarios, rapid installation and maintenance are particularly important. By incorporating snap-fit ​​structures 1 on both sides of the power supply box, users can easily and quickly assemble and disassemble the box, significantly improving installation and maintenance efficiency. LED displays may be subjected to various external forces during operation, such as wind and vibration. By installing a snap-fit ​​structure 1 on each side of the power supply box, dual-point locking is achieved, thereby enhancing the stability between the power supply box and the LED display body.

[0052] For users of LED displays, ease of operation and reliable performance are key to enhancing the user experience. The LED display in this embodiment employs a power box with a double-sided snap-fit ​​structure 1, allowing users to enjoy a more convenient and efficient operating experience when installing, replacing, and maintaining the power box. The installation requirements of LED displays vary depending on the application scenario. By setting snap-fit ​​structures 1 on both sides of the power box, different installation methods and space constraints can be flexibly adapted. Whether vertically or horizontally installed, whether a compact design or a large display system, the layout and size of the snap-fit ​​structure 1 can be adjusted to meet the requirements. This snap-fit ​​structure 1 not only facilitates operation but also has a certain anti-misoperation function. Through reasonable structural design and material selection, the stability and reliability of the snap-fit ​​structure 1 can be ensured during normal use. At the same time, the double-sided snap-fit ​​structure 1 can also prevent the power box from accidentally falling off or being damaged by external forces to a certain extent, improving the safety and reliability of the LED display.

[0053] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
