[0036] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0037] Reference Figures 1 to 6 To achieve the above-mentioned purpose, the present invention proposes a self-adjusting locking mechanism for the assembly flatness of a display screen cabinet, comprising a first positioning locking component 1, a second positioning locking component 2, a third positioning locking component 3, and a fourth positioning locking component 4 fixedly mounted at the four corners of the display screen cabinet; the first positioning locking component 1 comprises a first short-side positioning locking piece 11 and a first long-side positioning locking piece 15; the second positioning locking component 2 comprises a second short-side positioning locking piece 21 and a second long-side positioning locking piece 25; the third positioning locking component 3 comprises a third short-side positioning locking piece 31 and a third long-side positioning locking piece 34; the fourth positioning locking component 4 comprises a fourth short-side positioning locking piece 41 and a fourth long-side positioning locking piece 44;

[0038] The first short side positioning fastener 11 is used to be locked and connected with the third short side positioning fastener 31 on another adjacent display screen box; the second short side positioning fastener 21 is used to be locked and connected with the fourth short side positioning fastener 41 on another adjacent display screen box; the first long side positioning fastener 15 is locked and connected with the second long side positioning fastener 25 on another adjacent display screen box; the third long side positioning fastener 34 is locked and connected with the fourth long side positioning fastener 44 on another adjacent display screen box.

[0039] The display screen cabinet is provided with positioning and locking components at the four corners, so that the two display screens can be positioned and fixed by the corresponding positioning and locking components when they are spliced ​​together. The display screen cabinet itself is rectangular, including two long sides and two short sides. Each positioning and locking component is respectively provided with short side positioning locking pieces and long side positioning locking pieces corresponding to the long and short sides. When adjacent cabinets are connected, the locking pieces aligned with the short sides or the locking pieces aligned with the long sides can make the connection between the cabinets faster. The layout of the positioning and locking components at the four corners of different display screen cabinets is completely consistent, and this structure can make the structure of the positioning component easier to design, which can reduce production costs.

[0040] When two display screen boxes are spliced ​​together, they can be connected through the first short side of one box and the second short side of the other box, or the first long side of one box and the second long side of the other box. Specifically, the first short side positioning locking piece 11 is used to lock and connect with the third short side positioning locking piece 31 on the other adjacent display screen box; the second short side positioning locking piece 21 is used to lock and connect with the fourth short side positioning locking piece 41 on the other adjacent display screen box; the first long side positioning locking piece 15 is locked and connected with the second long side positioning locking piece 25 on the other adjacent display screen box; the third long side positioning locking piece 34 is locked and connected with the fourth long side positioning locking piece 44 on the other adjacent display screen box. With the help of the locking pieces, the two display screen boxes can be quickly locked to avoid their displacement, which can improve the three-dimensional positioning rate and make the entire structure more convenient to operate.

[0041] The layout of the positioning and locking components of different display screen cabinets is consistent, and different positioning and locking components are arranged in a prescribed order. After the cabinet arrives at the destination, the user can quickly determine the direction the cabinet should have, and use the positioning and locking pieces in different positions in the correct direction to quickly achieve the positioning and locking of multiple display screen cabinets. In this way, the three-dimensional positioning of adjacent display screen cabinets can be completed quickly and stably, and the two can be stably locked, which can effectively improve the operation speed.

[0042] See also Figures 1 to 6 The first short side positioning locking piece 11 is provided with a first short side fixing hole 12, and the third short side positioning locking piece 31 is provided with a third short side fixing hole 32. The first short side fixing hole 12 is detachably connected to the first short side locking handle with the first outer short side fixing section 13. When the first outer short side fixing section 13 is fixedly connected to the first short side fixing hole 12, it extends out of the first short side fixing hole 12 and can be fixedly connected to the third short side fixing hole 32 on another adjacent display screen box.

[0043] When the two boxes are oriented in the same direction and need to be locked by corresponding short side alignment, the first short side positioning locking piece 11 and the third short side positioning locking piece 31 limit each other, and the first short side fixing hole 12 on the first short side positioning locking piece 11 and the third short side fixing hole 32 on the third short side positioning locking piece 31 are connected. The first short side locking handle can facilitate the operation of the first outer short side fixing section 13. When one end of the first outer short side fixing section 13 is locked by the first short side positioning locking piece 11, it will extend out of the fixing hole of the first short side, pass through the fixing hole of the third short side, and be locked at the third short side. Through this structure, the short sides can be quickly used to fix two adjacent boxes. With the help of the positioning locking pieces, the two boxes can be aligned tightly, which can effectively improve the assembly accuracy.

[0044] See also Figures 5 and 6The first short side positioning fastener 11 is provided with a first short side positioning portion 14, and the third short side positioning fastener 31 is provided with a third short side positioning portion 33. The first short side positioning portion 14 can be positioned and matched with the third short side positioning portion 33 on another adjacent display screen box.

[0045] The two short side positioning parts can quickly position and limit each other when two adjacent boxes are locked by the short sides, so that the three-dimensional positioning between the boxes can be quickly completed.

[0046] In the present application, the structure of the first short side positioning portion 14 is the same as that of the second short side positioning portion 24, and the third short side positioning portion 33 is the same as that of the fourth short side positioning portion 43. The specific structure is that the first short side positioning portion 14 is a positioning lock structure, and the third short side positioning portion 33 is a positioning hole structure. The positioning lock is cylindrical, which can make the insertion more streamlined and improve the positioning rate. The connecting portion of the positioning lock is set towards the end of the positioning hole. Through the design of a structure selected from hemispherical, conical, and truncated cone shapes, it is beneficial for the positioning lock to position more quickly and improve the positioning efficiency. A clearance groove is provided on the outer periphery of the positioning lock. The clearance groove is used to cooperate with the chamfer of the outer periphery of the positioning hole to increase the contact area between the positioning hole and the positioning lock, so that the positioning of the upper and lower display screen boxes is more stable.

[0047] See also Figures 2 to 5 The second short side positioning lock piece 21 is provided with a second short side fixing hole 22, and the fourth short side positioning lock piece 41 is provided with a fourth short side fixing hole 42. The second short side fixing hole 22 is detachably connected to a second short side locking handle with a second short side outer fixing section 23. When the second short side outer fixing section 23 is fixedly connected to the second short side fixing hole 22, it extends out of the second short side fixing hole 22 and can be fixedly connected to the fourth short side fixing hole 42 on another adjacent display screen box.

[0048] When the two boxes are oriented in the same direction and need to be locked by corresponding short sides, the second short side positioning locking piece 21 and the fourth short side positioning locking piece 41 limit each other, and the second short side fixing hole 22 on the second short side positioning locking piece 21 is connected to the fourth short side fixing hole 42 on the fourth short side positioning locking piece 41. The second short side locking handle can facilitate the operation of the second outer short side fixing section. When one end of the second outer short side fixing section is locked by the second outer short side fixing end, it will extend out of the fixing hole, pass through the fixing hole of the fourth short side, and be locked at the fourth short side. Through this structure, the short sides can be used to quickly fix two adjacent boxes. The locking piece can ensure that the connected display screen boxes are flush, and can protect the display screen installed on the box to make the display effect stronger.

[0049] See also Figures 2 to 5The second short side positioning fastener 21 is provided with a second short side positioning portion 24, and the fourth short side positioning fastener 41 is provided with a fourth short side positioning portion 43. The second short side positioning portion 24 can be positioned and matched with the fourth short side positioning portion 43 on another adjacent display screen box.

[0050] The two short side positioning parts can be used to quickly position the two boxes. When the positioning is completed, the fixing holes of the two boxes are connected to each other, so that the boxes can quickly complete three-dimensional positioning and lock.

[0051] See also Figures 2 to 6 The first long side positioning locking piece 15 is provided with a first long side fixing hole 16, and the second long side positioning locking piece 25 is provided with a second long side fixing hole 26. The first long side fixing hole 16 is detachably connected to a first long side locking handle with a first outer long side fixing section 17. When the first outer long side fixing section 17 is fixedly connected to the first long side fixing hole 16, it extends out of the first long side fixing hole 16 and can be fixedly connected to the second long side fixing hole 26 on another adjacent display screen box.

[0052] When the two display screen boxes are locked by the long sides, the first long side of one display screen box and the second long side of the other display screen box can be quickly aligned and positioned with the help of the first long side positioning locking piece 15 and the second long side positioning locking piece 25. At this time, the fixing holes opened on the two long sides are connected to each other, and the first long side locking handle can facilitate the operation of the first outer long side fixing section 17. When one end of the first outer long side fixing section 17 is locked by the first long side positioning locking piece 15, it will extend out of the fixing hole, pass through the fixing hole of the second long side, and be locked at the second long side. Through this structure, the long sides can be used to quickly fix the two adjacent boxes. Through this structure, the boxes are flatter after being aligned and locked, and the gap after locking is reduced as much as possible, which effectively ensures the quality of the display screen and avoids damage to the display screen itself caused by uneven boxes.

[0053] See also Figures 2 to 6 The first long side positioning lock piece 15 is provided with a first long side positioning portion 18, and the second long side positioning lock piece 25 is provided with a second long side positioning portion 27. The first long side positioning portion 18 can be positioned and matched with the second long side positioning portion 27 on another adjacent display screen box.

[0054] The two long side positioning parts can quickly position and limit each other when two adjacent boxes are locked by the long sides, so that the three-dimensional positioning between the boxes can be quickly completed.

[0055] In the present application, the structure of the first long side positioning portion 18 is the same as the third long side positioning portion 37, and the second long side positioning portion 27 is the same as the fourth long side positioning portion 46. The specific structure is that the first long side positioning portion 18 is a positioning block structure, and the second long side positioning portion 27 is a positioning groove structure. The positioning block includes a locking portion and a guide portion. The locking portion is rectangular, and the guide portion is symmetrically arranged in at least two groups along the central axis of the locking portion. The thickness of the guide portion gradually decreases in the direction away from the locking portion. The side edge of the locking portion is conducive to sliding in the locking groove, which is conducive to the position of the left and right positioning connecting holes. The guide portion can facilitate the locking portion to be inserted into the locking groove, which can improve the rate of three-dimensional positioning. The positioning groove includes a locking groove and a guide groove. The guide groove is connected to one side of the locking groove along the direction of the guide part toward the locking part, and at least two groups are symmetrically provided along the central axis of the locking groove. The height of the guide groove gradually increases along the direction away from the locking groove. The height of the locking groove is consistent with the height of the locking part. The two can slide relative to each other, and the locking groove can limit the locking part, which can increase the alignment rate of the connecting hole. The guide groove is trumpet-shaped, which can facilitate the guide part to be inserted into the locking groove. The height of the guide part is less than the depth of the guide groove, which can effectively improve the connection efficiency.

[0056] See also Figures 2 to 5 The third long side positioning locking piece 34 is provided with a third long side fixing hole 35, and the fourth long side positioning locking piece 44 is provided with a fourth long side fixing hole 45. The third long side fixing hole 35 is detachably connected to a third long side locking handle with a third outer long side fixing section 36. When the third outer long side fixing section 36 is fixedly connected to the third long side fixing hole 35, it extends out of the third long side fixing hole 35 and can be fixedly connected to the fourth long side fixing hole 45 on another adjacent display screen box.

[0057] When the two display screen boxes are locked by the long sides, the third long side of one display screen box and the fourth long side of the other display screen box can be quickly aligned and positioned with the help of the third long side positioning locking piece 34 and the fourth long side positioning locking piece 44. At this time, the fixing holes opened on the two long sides are connected to each other, and the third long side locking handle can facilitate the operation of the third outer long side fixing section 36. When one end of the third outer long side fixing section 36 is locked by the third long side positioning locking piece 34, it will extend out of the fixing hole, pass through the fixing hole of the fourth long side, and be locked at the fourth long side. Through this structure, the long sides can be used to quickly fix two adjacent boxes.

[0058] In the present application, the outer long side fixing section and the long side locking handle as well as the outer short side fixing section and the short side locking handle have a variety of feasible structures. In a feasible embodiment, the fixing section can be connected with a spring so that when it is not locking, it can be suspended in the display screen box by the spring, or a connecting hole can be opened on the locking handle. When not working, the fixing section can be fixed by passing a bolt through the connecting hole. When in use, the fixing section can be pushed into the fixing hole of the other display screen box by pushing the spring with the handle for easy locking, or the lock on the handle can be released to enable the fixing section to quickly enter the working state.

[0059] See also Figures 2 to 5 The third long side positioning lock 34 is provided with a third long side positioning portion 37, and the fourth long side positioning lock 44 is provided with a fourth long side positioning portion 46. The third long side positioning portion 37 can be positioned and matched with the fourth long side positioning portion 46 on another adjacent display screen box.

[0060] In the present application, the structure of the first long side positioning portion 18 is the same as the third long side positioning portion 37, and the second long side positioning portion 27 is the same as the fourth long side positioning portion 46. When the two display screen boxes are locked by aligning the long sides, the third long side positioning portion 37 can limit each other with the fourth long side positioning portion 46 on another adjacent display screen box, and the boxes can be quickly positioned, which is conducive to the positioning and locking components to be put into operation quickly.

[0061] See also Figures 1 to 6 The first positioning and locking component 1, the second positioning and locking component 2, the third positioning and locking component 3 and the fourth positioning and locking component 4 can all be detachably fixedly mounted on the display screen box, or can be integrally formed on the display screen box.

[0062] The positioning and locking component itself can be detachably connected to the display screen box, so that the positioning and locking component structure is easy to maintain. There are many such detachable structures, including setting a positioning and locking component at the display screen box, and the two boxes are positioned and locked by the positioning and locking component. In order to avoid damage to the positioning and locking component, reinforcing ribs can be provided between the positioning components at adjacent corners, so that the positioning and locking components at the four corners can form a whole to bear the force, avoiding damage caused by excessive force on a single positioning component. Under this structure, each positioning and locking component can be disassembled, which is conducive to maintenance. If no reinforcing ribs are installed, the positioning and locking components can be extended so that after the installation of each positioning and locking component, its ends are connected to each other to form a reinforced structure.

[0063] In another feasible embodiment, no additional reinforcing ribs are provided between the two positioning and locking components at adjacent corners. Instead, when the positioning and locking components are produced, the reinforcing ribs and the positioning and locking components are integrally formed, so that the positioning and locking components are called a locking frame structure. Such a structure can further improve the strength of the positioning and locking components and facilitate installation.

[0064] At the same time, the positioning and locking component itself can be integrally formed with the display cabinet during production. This approach provides the highest strength, increases the service life of the mechanism, and optimizes the user experience.
