Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a safety rope connection component and a display screen. Background Technology

[0002] COB displays are primarily used in important settings such as commercial advertising, sports events, and transportation hubs. The display surface of a COB display is typically composed of multiple modular units spliced ​​together, and these modules are generally fixed using a magnetic attachment method. For safety and compliance requirements, safety ropes are often added to the modules.

[0003] In related technologies, there are two main ways to install the safety rope for COB displays: one is to pre-install a hanging part on the module and connect it to the cabinet with a steel wire rope / nylon rope and a hook. However, the steel wire rope / nylon rope is long and the hook is large, which can easily interfere with the installation of the module. The other is to directly loop or tie the steel wire rope / nylon rope to the reserved step or hole of the magnetic position of the module. This method has the problems of unstable fixation, easy loosening, high operation requirements, difficulty in unlocking, and large workload.

[0004] Therefore, there is an urgent need for a safety rope solution that is easy to install, reliably fixed, and does not interfere with the installation of modules. Utility Model Content

[0005] One objective of this utility model is to provide a safety rope connection component and a display screen, enabling convenient and reliable installation and fixation of COB display screen modules.

[0006] To achieve the above objectives, this utility model provides a safety rope connection assembly for connecting the display module in the display screen to the housing. The safety rope connection assembly includes: Pins are used to fix the display module, and the pins have locking positions formed on them; The connecting unit includes a main lock body, a connecting rope connected to the main lock body, and an unlocking ring rotatably sleeved on the outside of the main lock body; one end of the connecting rope away from the main lock body is used to connect to the housing; the main lock body has a mounting cavity, and the pin can pass through the mounting cavity; the connecting unit also includes a ball bearing, the side wall of the main lock body has a mounting hole communicating with the mounting cavity, the ball bearing is movably disposed in the mounting hole, and the side wall of the unlocking ring has an unlocking hole adapted to the ball bearing; The unlocking ring rotates relative to the main lock body to switch between a locked position and an unlocked position. The pin passes through the mounting cavity of the main lock body. When the unlocking ring rotates to the locked position, the ball can engage with the pin's engagement position to lock the pin to the main lock body. When the unlocking ring rotates to the unlocked position, the ball can move into the unlocking hole of the unlocking ring to disengage from the engagement position, thereby disengaging the pin from the main lock body.

[0007] In some embodiments of this application, the safety rope connection assembly further includes a reset elastic element capable of elastic deformation, the unlocking ring has an internal receiving groove, and the reset elastic element is disposed in the receiving groove; the inner wall of the unlocking ring with the receiving groove and the main lock body are both provided with mounting holes for installing the reset elastic element; When an external force drives the unlocking ring to rotate relative to the main lock body to the unlock position, the reset elastic element is in a deformed state; when the external force is released, the reset elastic element restores its elastic deformation, and the reset elastic element can drive the unlocking ring to rotate relative to the main lock body so that the unlocking ring moves to the locked position.

[0008] In some embodiments of this application, the safety rope connecting assembly further includes a pressing pin, the unlocking ring is provided with an assembly hole, and the side wall of the main lock body is provided with a limiting groove; one end of the pressing pin passes through the assembly hole, and the other end of the pressing pin is movably disposed in the limiting groove; when the unlocking ring rotates relative to the main lock body, the end of the pressing pin can slide in the limiting groove.

[0009] In some embodiments of this application, the safety rope connection assembly includes two pressing pins, which are symmetrically distributed along the axis of the unlocking ring.

[0010] In some embodiments of this application, the limiting groove is waist-shaped, and the extending direction of the limiting groove is consistent with the rotation trajectory direction of the unlocking ring relative to the main lock body.

[0011] In some embodiments of this application, the pin includes a base portion and a connecting portion disposed on the base portion. The side of the base portion opposite to the connecting portion is used to fix it to the display module. The connecting portion can pass through the mounting cavity. The side wall of the connecting portion forms the snap-fit ​​position, which is a groove structure. The inner wall of the connecting portion corresponding to the snap-fit ​​position is an arc surface, and the curvature of the snap-fit ​​position can be adapted to the spherical curvature of the ball.

[0012] In some embodiments of this application, the main lock body includes a lock body portion and a lock head connected to one end of the lock body portion, and the connecting rope is disposed on the side of the lock head opposite to the lock body portion; the lock body portion is provided with the mounting cavity and the mounting hole, and the unlocking ring is rotatably sleeved on the outside of the lock body portion, and the extending direction of the mounting cavity is consistent with the axial direction of the lock body portion.

[0013] In some embodiments of this application, the two ends of the main lock body corresponding to the mounting hole are a first end and a second end, respectively. The first end is connected to the mounting cavity, and the second end faces the unlocking ring. The inner wall of the main lock body near the first end of the mounting hole is a bracket-shaped curved surface.

[0014] In some embodiments of this application, the interior of the main lock body corresponding to the mounting hole includes a front end section and a rear end section connected in the extending direction of the mounting hole; the front end section is disposed near the first end, and the rear end section is disposed near the second end; The inner wall of the front end section is a bracket-shaped curved surface. The two ends of the front end section are a small end and a large end, respectively. The small end of the front end section faces the mounting cavity, and the large end of the front end section connects to the rear end section. The inner diameter of the small end is smaller than the outer diameter of the ball, and the inner diameter of the large end and the inner diameter of the rear end section are both larger than the outer diameter of the ball. When the unlocking ring is in the locked position, the inner wall of the unlocking ring blocks the port of the second end, and the spherical surface of the ball protrudes from the first end of the mounting hole and fits against the locking position; when the external force drives the unlocking ring to rotate relative to the main lock body, and the unlocking hole corresponds to the rear end section, the ball can move through the rear end section into the unlocking hole to disengage from the locking position.

[0015] This utility model also provides a display screen, including a housing, multiple display modules, and a safety rope connecting assembly as described above. The multiple display modules are spliced ​​together. The safety rope connecting assembly is provided in multiple sets, and each display module is provided with a set of the safety rope connecting assembly between it and the housing. The pin is fixed on the display module, and the end of the connecting rope is connected and fixed to the housing.

[0016] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: In the safety rope connection component and display screen of this utility model, when the unlocking ring is in the locked position, the ball is engaged in the locking position of the pin. The mechanical locking structure realizes the rigid locking of the pin and the main lock body, which can effectively resist the external forces such as gravity and vibration of the display module, prevent the pin from falling out, avoid the risk of the display module falling off, and ensure the structural stability of the display screen after installation. When unlocking, it is only necessary to rotate the unlocking ring to the unlocking position, and the ball can enter the unlocking hole of the unlocking ring and disengage from the locking position of the pin. The pin can be quickly removed from the main lock body without the need for complex tools such as wrenches and screwdrivers. The operation steps are simple, which improves the installation efficiency of the display module and facilitates the disassembly operation when maintaining and replacing the module later.

[0017] In addition, the safety rope connection assembly has a high degree of integration of components such as the main lock body, unlocking ring, and ball bearings. The unlocking ring is sleeved on the outside of the main lock body, and the ball bearings are embedded in the mounting holes of the main lock body. The overall structure is compact and occupies little space. It is suitable for the narrow installation gap between the internal module of the display screen and the cabinet, avoiding interference with the installation of the display module due to excessive structural volume or complexity, and ensuring the overall layout of the display screen.

Detailed Implementation

[0028] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0029] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] See Figure 1 and Figure 2 One embodiment of this application provides a safety rope connection assembly 100, which is used to connect the display module 300 in the display screen 1000 to the housing 200. The safety rope connection assembly 100 includes a pin 10 and a connection unit 20.

[0032] The pin 10 is used to fix the display module 300, and a snap-fit ​​position 101 is formed on the pin 10. The connecting unit 20 includes a main lock body 21, a connecting rope 22 connected to the main lock body 21, and an unlocking ring 23 rotatably sleeved on the outside of the main lock body 21. The end of the connecting rope 22 facing away from the main lock body 21 is used to connect to the housing 200. The main lock body 21 has a mounting cavity 210, and the pin 10 can pass through the mounting cavity 210. The connecting unit 20 also includes a ball bearing 24. The side wall of the main lock body 21 has a mounting hole 211 communicating with the mounting cavity 210. The ball bearing 24 is movably disposed in the mounting hole 211. The side wall of the unlocking ring 23 has an unlocking hole 231 adapted to the ball bearing 24.

[0033] The unlocking ring 23 rotates relative to the main lock body 21 to switch between a locked position and an unlocked position. The pin 10 passes through the mounting cavity 210 of the main lock body 21. When the unlocking ring 23 rotates to the locked position, the ball bearing 24 engages with the engagement position 101 of the pin 10, locking the pin 10 to the main lock body 21. When the unlocking ring 23 rotates to the unlocked position, the ball bearing 24 moves into the unlocking hole 231 of the unlocking ring 23, disengaging from the engagement position 101, thus releasing the pin 10 from the main lock body 21.

[0034] For the safety rope connection assembly 100 of this application, when the unlocking ring 23 is in the locked position, the ball bearing 24 engages with the locking position 101 of the pin 10, and the mechanical locking structure achieves rigid locking between the pin 10 and the main lock body 21. This effectively resists external forces such as gravity and vibration of the display module 300, prevents the pin 10 from coming out, avoids the risk of the display module 300 falling off, and ensures the structural stability of the display screen 1000 after installation. When unlocking, simply rotate the unlocking ring 23 to the unlocking position, and the ball bearing 24 can enter the unlocking hole 231 of the unlocking ring 23 and disengage from the locking position 101 of the pin 10. The pin 10 can be quickly removed from the main lock body 21 without the need for complex tools such as wrenches and screwdrivers. The operation steps are simple, improving the installation efficiency of the display module 300 and facilitating disassembly operations during later maintenance and module replacement.

[0035] Furthermore, the safety rope connection assembly 100 features a high degree of integration among components such as the main lock body 21, the unlocking ring 23, and the ball bearing 24. The unlocking ring 23 is sleeved on the outside of the main lock body 21, and the ball bearing 24 is embedded in the mounting hole 211 of the main lock body 21. The overall structure is compact and occupies little space, which is suitable for the narrow installation gap between the internal module of the display screen 1000 and the housing 200. This avoids interference with the installation of the display module 300 due to excessive structural volume or complexity, and ensures the overall layout of the display screen 1000.

[0036] In some embodiments of this application, such as Figure 3As shown, the pin 10 is used to fix it to the display module 300. The pin 10 may include a chassis portion 11 and a connecting portion 12 disposed on the chassis portion 11. The side of the chassis portion 11 away from the connecting portion 12 is used to fix it to the display module 300. The connecting portion 12 can pass through the mounting cavity 210 of the main lock body 21.

[0037] In some examples, the chassis portion 11 is fixed to the PCB board of the display module 300 by welding. In this example, the chassis portion 11 has a large contact area with the PCB board, which evenly distributes the weight and external force of the display module 300, avoiding PCB board deformation or solder joint detachment caused by single-point force; and the chassis portion 11 and the connecting portion 12 form a T-shaped structure, which can form a mechanical stop with the chassis portion 11 and the PCB board when the pin 10 is subjected to an upward pulling force, significantly improving the pull-out resistance and preventing accidental detachment.

[0038] In some examples, the sidewall of the connecting portion 12 forms a snap-fit ​​position 101, which is a groove structure that is arranged around the sidewall of the connecting portion 12. In this example, the inner wall of the connecting portion 12 corresponding to the snap-fit ​​position 101 is an arc surface, and the curvature of the snap-fit ​​position 101 can be adapted to the spherical curvature of the ball 24.

[0039] The spherical surface of the ball bearing 24 can fit against the arcuate surface of the locking position 101, allowing the ball bearing 24 to effectively engage at the locking position 101 and ensuring a locking effect. Furthermore, the arcuate surface provides a precise movement trajectory for the ball bearing 24, making the rotation of the unlocking ring 23 from the locked position to the unlocked position stable and controllable, avoiding jamming or stuck-out phenomena. In addition, when the unlocking ring 23 rotates, the ball bearing 24 rolls on the arcuate surface rather than slides, significantly reducing frictional resistance and making operation more effortless.

[0040] Combination Figure 4 , Figure 5 as well as Figure 6 As shown in the present application, the connecting unit 20 may include a main lock body 21, a connecting rope 22, an unlocking ring 23, and a ball bearing 24.

[0041] In some embodiments of this application, the main lock body 21 may include a lock body portion 212 and a lock head 213 connected to one end of the lock body portion 212, with a connecting rope 22 disposed on the side of the lock head 213 facing away from the lock body portion 212. The lock body portion 212 is provided with a mounting cavity 210 and a mounting hole 211, and an unlocking ring 23 is rotatably sleeved on the outside of the lock body portion 212. The extending direction of the mounting cavity 210 is consistent with the axial direction of the lock body portion 212.

[0042] In some examples, combined Figure 4 , Figure 6 and Figure 7As shown, the lock head 213 includes a plate portion 2131 and a connecting portion 2132 disposed on the plate portion 2131. The lock body portion 212 is fixed on the surface of the plate portion 2131 facing away from the connecting portion 2132. The periphery of the plate portion 2131 extends outward beyond the periphery of the lock body portion 212.

[0043] In this example, the connecting portion 2132 is provided with a through hole 2133, and the end of the connecting rope 22 is threaded through and fixed in the through hole 2133. The extending direction of the through hole 2133 is perpendicular to the extending direction of the lock body portion 212.

[0044] The extension direction of the perforation 2133 is perpendicular to the extension direction of the lock body 212, so that the tension direction of the connecting rope 22 is perpendicular to the axis of the lock body 212, that is, the insertion direction of the pin 10. The tension will not be transmitted to the locking structure formed by the ball 24 and the pin 10 inside the lock body 212, avoiding the torque generated by the tension of the connecting rope 22 from interfering with the locking state. This effectively prevents the unlocking ring 23 from rotating accidentally, the ball 24 from disengaging from the locking position 101, etc., ensuring the stability of the locking structure and improving the overall stability of the locking state.

[0045] In this application, such as Figure 4 and 8 As shown, the unlocking ring 23 is a ring-shaped structure and is sleeved on the outside of the lock body 212. The unlocking ring 23 can rotate relative to the main lock body 21 so as to switch between the locked position and the unlocked position.

[0046] In some embodiments of this application, the safety rope connection assembly 100 may further include a pressing pin 25, an unlocking ring 23 having an assembly hole 232, and a limiting groove 214 on the side wall of the main lock body 21. One end of the pressing pin 25 passes through the assembly hole 232, and the other end of the pressing pin 25 is movably disposed in the limiting groove 214. When the unlocking ring 23 rotates relative to the main lock body 21, the end of the pressing pin 25 can slide in the limiting groove 214.

[0047] In some examples, such as Figure 5 As shown, the limiting groove 214 is waist-shaped, and the extension direction of the limiting groove 214 is consistent with the rotation trajectory direction of the unlocking ring 23 relative to the main lock body 21.

[0048] When the unlocking ring 23 rotates relative to the main lock body 21, the unlocking ring 23 can transmit the rotational force to the limiting groove 214 of the main lock body 21 through the pressing pin 25. The end of the pressing pin 25 slides inside the limiting groove 214, which can provide a stable guide for the rotation of the unlocking ring 23 and prevent the unlocking ring 23 from jamming, shifting or tilting.

[0049] By setting the length of the limiting groove 214, the sliding stroke of the pressing pin 25 can be limited, thereby restricting the rotation angle of the unlocking ring 23. This setting can prevent the unlocking ring 23 from rotating too much, causing misalignment between the ball 24 and the unlocking hole 231, and can also block the pressing pin 25 through the end point of the limiting groove 214, ensuring that the ball 24 can be positioned and moved into the unlocking hole 231, ensuring that the unlocking action is completed in one go.

[0050] In some examples, the safety rope connection assembly 100 includes two crimping pins 25, which are symmetrically distributed along the axis of the unlocking ring 23.

[0051] Two pressing pins 25 are symmetrically distributed along the axis of the unlocking ring 23. When the unlocking ring 23 rotates, the pressing pins 25 on both sides simultaneously bear the torque and transmit it to the main lock body 21, so that the unlocking ring 23 is evenly stressed in the circumference and completely avoids the problem of uneven load when the pressing pin 25 on one side is under load. This arrangement can prevent the unlocking ring 23 from tilting, radially shifting, or even jamming with the lock body 212 due to unilateral force, ensuring that the rotation process is always smooth.

[0052] Furthermore, the symmetrically distributed pressing pins 25 effectively provide double-sided rotational guides for the unlocking ring 23, ensuring that the unlocking ring 23 can only rotate along its own axis and cannot produce radial sway or offset. Even under complex working conditions such as vibration and external force collisions, the unlocking ring 23 can still maintain a precise rotational trajectory, improving operational stability.

[0053] like Figure 2 and Figure 7 As shown in this application, the lock body 212 has a mounting hole 211 on its side wall, which communicates with the mounting cavity 210. The ball bearing 24 is movably disposed in the mounting hole 211. The unlocking ring 23 has an unlocking hole 231 for accommodating the ball bearing 24, and the outer diameter of the unlocking hole 231 is smaller than the diameter of the ball bearing 24.

[0054] In some embodiments of this application, the two ends of the main lock body 21 corresponding to the mounting hole 211 are a first end 2111 and a second end 2112, respectively. The first end 2111 is connected to the mounting cavity 210, and the second end 2112 faces the unlocking ring 23. The inner wall of the first end 2111 of the main lock body 21 near the mounting hole 211 is a bracket curved surface.

[0055] The inner wall of the first end 2111 of the mounting hole 211 is a bracket-shaped curved surface. This bracket-shaped curved surface can form a hugging effect on the ball 24, preventing the ball 24 from completely detaching from the mounting hole 211 even under severe vibration, thus preventing the ball 24 from falling out of the first end 2111 of the mounting hole 211 and providing reliable anti-drop protection.

[0056] In some examples, the interior of the main lock body 21 corresponding to the mounting hole 211 includes a connecting front section 2113 and a rear section 2114 in the extending direction of the mounting hole 211. The front section 2113 is located near the first end 2111, and the rear section 2114 is located near the second end 2112. The inner wall of the front section 2113 is a bracket-shaped curved surface, and the two ends of the front section 2113 are a small end and a large end, respectively. The small end of the front section 2113 faces the mounting cavity 210, and the large end of the front section 2113 connects to the rear section 2114.

[0057] The inner diameter of the smaller end is smaller than the outer diameter of the ball 24, while the inner diameters of the larger end and the rear section 2114 are both larger than the outer diameter of the ball 24. The inner diameter of the smaller end of the front section 2113 is smaller than the outer diameter of the ball 24, thus forming a mechanical stop. In the locked state, the ball 24 cannot fully enter the mounting cavity 210, but can only partially protrude from the smaller end and engage with the locking position 101 of the pin 10, ensuring the effective contact area between the ball 24 and the locking position 101 and ensuring the locking effect. At the same time, the limiting effect of the smaller end keeps the ball 24 in a partially exposed locking posture, so that even if subjected to vibration or external impact, it will not disengage from the locking position 101, greatly improving the reliability of the lock.

[0058] In this example, when the unlocking ring 23 is in the locked position, the inner wall of the unlocking ring 23 blocks the port of the second end 2112, and the spherical surface of the ball 24 protrudes from the first end 2111 of the mounting hole 211 and fits against the locking position 101. An external force drives the unlocking ring 23 to rotate relative to the main lock body 21, and when the unlocking hole 231 corresponds to the rear end section 2114, the ball 24 can move through the rear end section 2114 into the unlocking hole 231 to disengage from the locking position 101.

[0059] When the unlocking ring 23 is in the locked position, its inner wall blocks the second end 2112 of the mounting hole 211, and the rear section 2114 forms a closed space. The ball 24 is restricted in the front section 2113 and cannot move toward the rear section 2114, so that the ball 24 remains in the locked state. When the unlocking ring 23 rotates to the unlocking position, the unlocking hole 231 corresponds precisely with the rear section 2114, and the ball 24 gains the space to move toward the second end 2112, thereby disengaging from the locked position 101.

[0060] In this configuration, the segmented structure of the mounting hole 211 can provide dual constraints on the movement range of the ball 24. Specifically, when the unlocking ring 23 is in the locked position, the small end of the front section 2113 can prevent the ball 24 from entering the mounting cavity 210; when the unlocking ring 23 is in the unlocked position, the rear section 2114 is connected to the unlocking hole 231 to accommodate the ball 24. The size of the ball 24 is larger than the outer diameter of the unlocking hole 231, and the ball 24 is still confined in the unlocking hole 231 and will not come off the main lock body 21.

[0061] In some embodiments of this application, two ball bearings 24 are provided, and two main lock bodies 21 are symmetrically arranged along the axial direction of the main lock bodies 21. Two mounting holes 211 are provided at corresponding positions of the main lock bodies 21, and two unlocking holes 231 are provided at corresponding positions of the unlocking ring 23.

[0062] Two ball bearings 24 are symmetrically arranged along the axis of the main lock body 21. In the locked state, they are simultaneously engaged with the annular engagement position 101 of the pin 10, forming a double-sided symmetrical engagement. The engagement contact area is doubled, and the locking force is evenly distributed on both sides of the pin 10. This can effectively resist the gravity, shaking impact and torsional force of the display module 300, and prevent the pin 10 from tilting or falling out due to force on one side. This greatly improves the locking strength between the pin 10 and the main lock body 21, and is especially suitable for the connection requirements of large-size and heavy display modules 300.

[0063] like Figure 5 , Figure 6 as well as Figure 8 As shown, in some embodiments of this application, the safety rope connection assembly 100 may further include a resilient resetting elastic element 26 capable of elastic extension and retraction. The unlocking ring 23 has an internal receiving groove 230, and the resetting elastic element 26 is disposed in the receiving groove 230. The inner wall of the unlocking ring 23 with the receiving groove 230 and the main lock body 21 are both provided with mounting holes for installing the resetting elastic element 26.

[0064] In this embodiment, the reset elastic element 26 is a torsion spring. When an external force drives the unlocking ring 23 to rotate relative to the main lock body 21 to the unlock position, the reset elastic element 26 is in a deformed state. When the external force is released, the reset elastic element 26 restores its elastic deformation, and the reset elastic element 26 can drive the unlocking ring 23 to rotate relative to the main lock body 21, so that the unlocking ring 23 moves to the locked position.

[0065] By setting the reset elastic element 26, the unlocking ring 23 can automatically return to the locked position after the external force is released, without the need for manual reset. When the operator completes the unlocking operation of the unlocking ring 23 and releases his hand, the reset elastic element 26 can release the deformation potential energy, driving the unlocking ring 23 to return to the locked position.

[0066] Both the unlocking ring 23 and the main lock body 21 are provided with mounting holes for installing the reset elastic member 26. In some examples, the inner wall of the receiving groove 230 of the unlocking ring 23 is provided with a first fastening hole 233, and the surface of the plate portion 2131 where the lock body portion 212 is provided with a second fastening hole 2134. One end of the reset elastic member 26 is connected to the first fastening hole 233, and the other end is connected to the second fastening hole 2134, thereby being assembled between the unlocking ring 23 and the main lock body 21.

[0067] In addition, such as Figure 4As shown, in some embodiments of this application, the connecting rope 22 includes a rope body 221 and a connecting buckle 222 disposed at one end of the rope body 221. In some examples, the rope body 221 can be a spring-loaded steel wire rope, which is in a contracted state in its natural state, is small in size, occupies very little space, and can be stretched when stretched.

[0068] The end of the rope body 221 away from the connecting buckle 222 forms a locking ring structure, which passes through the through hole 2133 of the main lock body 21 to achieve a fixed connection between the connecting rope 22 and the main lock body 21. The connecting buckle 222 has a through hole 2221 for the screw to pass through, thereby fixing the connecting buckle 222 to the housing 200 and thus fixing the connecting rope 22 to the housing 200.

[0069] Furthermore, such as Figure 9 As shown, one embodiment of this application also provides a display screen 1000, which includes a housing 200, a plurality of display modules 300, and a safety rope connection assembly 100. The structure of the safety rope connection assembly 100 has been described above and will not be repeated here.

[0070] Multiple display modules 300 are spliced ​​together, and the display surfaces of the multiple display modules 300 can be spliced ​​together to form a complete display surface of the display screen 1000. Multiple sets of safety rope connection assemblies 100 are provided. Each display module 300 is provided with a set of safety rope connection assemblies 100 between it and the housing 200. The pin 10 is fixed on the display module 300, and the end of the connecting rope 22 is connected and fixed to the housing 200.

[0071] When assembling the display module 300 with the housing 200, firstly, the pin 10 is welded and fixed to the PCB board of the display module 300, and the end of the connecting rope 22 is fixed to the surface of the housing 200 with screws; then, the main lock body 21 is aligned with the pin 10, the unlocking ring 23 is rotated to the unlock position and the pin 10 is inserted into the mounting cavity 210 of the main lock body 21, and then the unlocking ring 23 is released. Under the deformation potential energy of the reset elastic element 26, the unlocking ring 23 returns to the locked position, and the ball 24 moves and engages with the locking position 101 of the pin 10, thereby preventing the pin 10 from falling out and locking the pin 10 with the main lock body 21. Finally, the display module 300 is magnetically fixed to the housing 200. The locking of the pin 10 with the main lock body 21 prevents the display module 300 from falling off the housing 200.

[0072] When it is necessary to separate the connecting rope 22 from the display module 300, rotate the unlocking ring 23 to the unlock position, so that the unlocking hole 231 corresponds to the mounting hole 211, allowing the ball bearing 24 to move toward the unlocking hole 231 to disengage from the locking position 101, thereby disengaging the pin 10 from the main lock body 21 and separating the display module 300 from the connecting rope 22. After releasing the unlocking ring 23, the unlocking ring 23 can return to the locked position under the deformation potential energy of the reset elastic element 26.

[0073] For the safety rope connection assembly and display screen of this application, when the unlocking ring is in the locked position, the ball engages with the pin's locking position. The mechanical locking structure achieves rigid locking between the pin and the main lock body, which can effectively resist external forces such as the weight and vibration of the display module, prevent the pin from falling out, avoid the risk of the display module falling off, and ensure the structural stability of the display screen after installation. When unlocking, simply rotate the unlocking ring to the unlocking position, and the ball can enter the unlocking hole of the unlocking ring and disengage from the pin's locking position. The pin can be quickly removed from the main lock body without the need for complex tools such as wrenches and screwdrivers. The operation steps are simple, which improves the installation efficiency of the display module and facilitates disassembly operations when maintaining or replacing the module later.

[0074] In addition, the safety rope connection assembly has a high degree of integration of components such as the main lock body, unlocking ring, and ball bearings. The unlocking ring is sleeved on the outside of the main lock body, and the ball bearings are embedded in the mounting holes of the main lock body. The overall structure is compact and occupies little space. It is suitable for the narrow installation gap between the internal module of the display screen and the cabinet, avoiding interference with the installation of the display module due to excessive structural volume or complexity, and ensuring the overall layout of the display screen.

[0075] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
