Description

Technical Field

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

[0002] In the commercial rental screen sector, to meet diverse display needs across different scenarios, rental screens are typically composed of multiple display units spliced ​​together. Each display unit consists of a cabinet and display modules mounted on the cabinet. In practical applications, multiple cabinets are interconnected via interlocking locks. These interlocking locks are designed to adjust the angle between adjacent cabinets, allowing the rental screen to flexibly adjust its form according to the usage scenario, thus enhancing the applicability and flexibility of commercial rental screens.

[0003] During long-term use, the frequent splicing, disassembly, and angle adjustments of the rental screens cause the movable connecting locks to be subjected to constant friction, gradually wearing down their surface materials and reducing connection accuracy and stability. During transportation, vehicle bumps and vibrations subject the connecting locks to continuous external impacts, leading to fatigue stress in their internal structure. Over time, the connecting locks are prone to friction damage or fatigue fracture, affecting not only the normal splicing and angle adjustment functions of the large screen but also potentially causing misalignment and excessive gaps in the displayed image. This reduces the display quality and reliability of the large screen, increases maintenance costs and usage risks, and fails to meet the requirements for efficient and stable operation of large screens in commercial rental scenarios.

[0016] Preferably, the second positioning member has a coupled state and a decoupled state, and the second positioning member rotates about the adjusting rod relative to the second connecting member to switch between the coupled state and the decoupled state;

[0017] When the second positioning member is in the coupling state, the second limiting end is embedded in the second positioning groove;

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Example 1

[0040] Combination Figures 1 to 9 As shown, the connecting component of this utility model is schematically illustrated, including a first connecting component 10 and a second connecting component 20 that are slidably connected to each other.

[0041] like Figure 1 and Figure 3In order to limit the sliding stroke between the first connecting component 10 and the second connecting component 20, the first connecting component 10 is provided with an arc-shaped guide slot 12, and the second connecting component 20 is provided with a limiting post 23 that is movably inserted through the guide slot 12. The second connecting component 20 is slidably connected to the guide slot 12 of the first connecting component 10 through the limiting post 23, and the guide slot 12 can also limit the sliding stroke of the limiting post 23.

[0042] like Figure 4 and Figure 5 A connecting plate 30 is detachably provided on the first connecting component 10. The connecting plate 30 is arranged along the sliding trajectory between the first connecting component 10 and the second connecting component 20. When the first connecting component 10 and the second connecting component 20 slide relative to each other, the connecting plate 30 slidably abuts against the second connecting component 20. The connecting plate 30 can improve the tensile strength of the first connecting component 10 and ensure that the first connecting component 10 and the second connecting component 20 can be stably connected. The detachable connecting plate 30 is also easy to disassemble and replace. When the connecting plate 30 is severely worn, it can be removed and replaced with a new one. The connecting plate 30 is provided with a plurality of first positioning grooves 31. The inner surface of the first positioning grooves 31 is spherical. The plurality of first positioning grooves 31 are arranged along the sliding trajectory between the first connecting component 10 and the second connecting component 20.

[0043] Specifically, in combination Figure 1 and Figure 5 As shown, the first connecting component 10 is provided with a mounting cavity 11, and the connecting plate 30 is detachably embedded in the mounting cavity 11. The bottom wall of the mounting cavity 11 is provided with a connecting hole. The connecting plate 30 can be detachably connected to the connecting hole by existing fasteners such as screws or bolts. The inner side wall of the mounting cavity 11 abuts against the outer side wall of the connecting plate 30. The mounting cavity 11 can accommodate the connecting plate 30 and reduce the degree of outward protrusion of the connecting plate 30 on the first connecting component 10. Secondly, it can restrict the degree of freedom of the connecting plate 30, so that the connecting plate 30 and the first connecting component 10 share the load and improve the overall tensile strength of the first connecting component 10.

[0044] like Figure 4The second connecting component 20 is movably provided with a first positioning member 21, meaning the first positioning member 21 can move relative to the second connecting component 20. The end of the first positioning member 21 has a spherical first limiting end 211, which is embedded in the first positioning groove 31. The end of the first positioning member 21 and the first positioning groove 31 have spherical contact, resulting in a larger contact area and reducing the likelihood of breakage and failure. Furthermore, when the first positioning member 21 is embedded in the first positioning groove 31, it prevents the first connecting component 10 and the second connecting component 20 from sliding relative to each other. By changing the first positioning groove 31 that engages with the first positioning member 21, the included angle between the first connecting component 10 and the second connecting component 20 can be adjusted and locked.

[0045] Furthermore, such as Figure 2 and Figure 3 The second connecting component 20 has a mounting hole 22, the extension trajectory of the mounting hole 22 is arc-shaped, the first connecting component 10 is slidably inserted into the mounting hole 22, part of the connecting plate 30 is located in the mounting hole 22, and the limiting post 23 is located in the mounting hole 22.

[0046] like Figures 5 to 7 The connecting assembly also includes a second positioning member 40 and an adjusting rod 50. One end of the second positioning member 40 is movably connected to the second connecting component 20, specifically, the second positioning member 40 is slidably connected to the second connecting component 20. The other end of the second positioning member 40 is provided with a second limiting end 41, which has a spherical surface. The connecting plate 30 is provided with a plurality of second positioning grooves 32, which are arranged along the sliding trajectory between the first connecting component 10 and the second connecting component 20. The inner surface of the second positioning groove 32 has a spherical surface, and the second limiting end 41 is embedded in the second positioning groove 32. The second limiting end 41 and the second positioning groove 32 have a spherical contact, resulting in a larger contact area and making the inner surface of the second positioning groove 32 and the second limiting end 41 less prone to breakage and failure. Similarly, the first positioning member 21 is connected to the second connecting member 20 through the first elastic member 60. The end of the first positioning member 21 is referred to as the first limiting end 211. The first limiting end 211 has a spherical surface and is embedded in the first positioning groove 31 under the elastic force of the first elastic member 60.

[0047] In this embodiment, the first positioning member 21 is used to provide a secondary locking function. When the user adjusts the included angle between the first connecting member 10 and the second connecting member 20, the user needs to apply force to compress the first elastic member 60 and drive the second positioning member 40 to slide relative to the second connecting member 20, so that the first positioning member 21 and the second positioning member 40 move away from the connecting plate 30, thereby causing the first limiting end 211 to disengage from the first positioning groove 31 and the second limiting end 41 to disengage from the second positioning groove 32. After the adjustment of the included angle between the first connecting member 10 and the second connecting member 20 is completed, the first elastic member 60 is released. The first limiting end 211 is embedded in the first positioning groove 31 under the elastic force of the first elastic member 60, and the second positioning member 40 is driven to slide relative to the second connecting member 20 so that the second limiting end 41 is embedded in the second positioning groove 32.

[0048] Furthermore, such as Figure 5 The adjusting rod 50 has a head end 50a and a tail end 50b. The head end 50a of the adjusting rod 50 is movably connected to one side of the second connecting member 20, and the tail end 50b of the adjusting rod 50 is provided with a limiting block 51 extending radially therefrom. The limiting block 51 is located on the other side of the second connecting member 20. In this embodiment, the second connecting member 20 has a guide hole 24, such as... Figure 6 One end of the guide hole 24 is located on one side of the second connecting component 20, and the other end of the guide hole 24 passes through the mounting hole 22. The second positioning member 40 is slidably inserted through the guide hole 24 to allow the second limiting end 41 on the second positioning member 40 to move closer to or further away from the connecting plate 30. Figure 5 The second positioning member 40 has a through hole 42, and the tail end 50b of the adjusting rod 50 slidably passes through the through hole 42. The limiting block 51 abuts against the second positioning member 40. When the adjusting rod 50 slides relative to the second connecting member 20 and moves away from the end with the limiting block 51, the second limiting end 41 on the second positioning member 40 can be embedded into the second positioning groove 32 on the connecting plate 30. The adjusting rod 50 can be driven to slide relative to the second connecting member 20 by an existing transmission mechanism, which includes, but is not limited to, a nut and screw mechanism. For example, a throttle 53 can be provided at the head end 50a of the adjusting rod 50, which can be combined with... Figures 5 to 7 As shown, the tail end 50b of the adjusting rod 50 is provided with an external thread 52, and the limiting block 51 is provided with a screw hole 512. The external thread 52 is movably connected to the screw hole 512, and the limiting block 51 is slidably connected to the second connecting member 20. When the throttle 53 is rotated with force, the adjusting rod 50 rotates relative to the second connecting member 20, and the external thread 52 and the screw hole 512 drive the limiting block 51 to slide relative to the second connecting member 20 along the axial direction of the adjusting rod 50.

[0049] Furthermore, in order to release the angle lock between the first connecting member 10 and the second connecting member 20 under specific working conditions (such as transportation conditions), the second positioning member 40 has a coupling state and a decoupling state. The second positioning member 40 rotates about the adjusting rod 50 relative to the second connecting member 20 to switch between the coupling state and the decoupling state. When the second positioning member 40 is in the coupled state, the second limiting end 41 is embedded in the second positioning groove 32. At this time, the second positioning member 40 can force the second limiting end 41 to be embedded in a certain second positioning groove 32 under the elastic force of the second elastic member 70, thereby locking the first connecting member 10 and the second connecting member 20. When the second positioning member 40 is in the decoupled state, the second limiting end 41 and the second positioning groove 32 are misaligned, which causes the second limiting end 41 to be unable to be embedded in any second positioning groove 32. The second positioning member 40 cannot lock the first connecting member 10 and the second connecting member 20. Under specific working conditions, unlocking can prevent the second limiting end 41 and the second positioning groove 32 from being worn by unnecessary impacts.

[0050] The end face of the second positioning member 40 is provided with a first limiting protrusion 43 and a second limiting protrusion 44, such as... Figure 8 and Figure 9The number of first limiting protrusions 43 can be one or more, and similarly, the number of second limiting protrusions 44 can be one or more. The first limiting protrusions 43 and the second limiting protrusions 44 are located on different radial directions on the second positioning member 40. More specifically, the second positioning member 40 is a rotating structure, and both the first limiting protrusions 43 and the second limiting protrusions 44 extend along the radial direction of the second positioning member 40, with an included angle between them. A second elastic member 70 is provided between the second positioning member 40 and the second connecting member 20. The limiting block 51 has a limiting groove 511 opposite to the second positioning member 40. One of the first limiting protrusions 43 and the second limiting protrusions 44 is embedded in the limiting groove 511 under the elastic force of the second elastic member 70. When the adjusting rod 50 slides away from the direction where it has the limiting block 51 relative to the second connecting member 20, the limiting block 51 pushes the second positioning member 40 to move relative to the second connecting member 20, so that the second limiting end 41 on the second positioning member 40 is embedded in the second positioning groove 32 on the connecting plate 30. At this time, the second elastic member 70 is compressed. When the adjusting rod 50 slides towards the direction where it has the limiting block 51 relative to the second connecting member 20, the second elastic member 70 first gradually rebounds from the compressed state to push the second positioning member 40 away from the connecting plate 30. The second limiting end 41 disengages from the second positioning groove 32. During this stage, the second positioning member... 40. Release the lock on the first connecting component 10 and the second connecting component 20; then, the user can apply force to directly push the second positioning component 40 toward the connecting plate 30, forcing the first limiting protrusion 43 to disengage from the limiting groove 511, or forcing the second limiting protrusion 44 to disengage from the limiting groove 511, and then apply force to rotate the second positioning component 40 to switch the decoupling state or coupling state of the second positioning component 40, release the second positioning component 40, and under the elastic force of the second elastic component 70, the first limiting protrusion 43 or the second limiting protrusion 44 will engage with the limiting groove 511 to realize the switching of the decoupling state and coupling state of the second positioning component 40.

[0051] like Figure 4 and Figure 8 To facilitate the user to push and rotate the second positioning component 40, a lever 45 is provided on the second positioning component 40, and the lever 45 is arranged adjacent to the limiting block 51.

[0052] Example 2

[0053] This embodiment discloses a display device, including a first housing, a second housing, and a connection component as described above. The first housing is connected to a first connection component 10, and the second housing is connected to a second connection component 20.

[0054] In summary, the first connecting component 10 and the second connecting component 20 are slidably connected to each other, and can connect two adjacent boxes to adjust the angle between the boxes. The connecting plate 30 detachably connected to the first connecting component 10 has multiple first positioning grooves 31. The first positioning member 21 on the second connecting component 20 can be embedded in a certain first positioning groove 31 to prevent the first connecting component 10 and the second connecting component 20 from sliding relative to each other. By changing the first positioning groove 31 that engages with the first positioning member 21, the included angle between the first connecting component 10 and the second connecting component 20 can be adjusted and locked. The added embedded connecting plate 30 not only improves the tensile strength of the first connecting component 10, thereby improving the connection stability of the first connecting component 10 and the second connecting component 20, but also facilitates disassembly and replacement to prevent the first connecting component 10 and the second connecting component 20 from being unable to lock stably due to long-term wear of the connecting plate 30.
