DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0020] like Figures 1 to 4 As shown, a splicing type LED display screen includes a splicing mechanism and a display screen 1. A plurality of display screens 1 are spliced ​​in a rectangular array. Two adjacent display screens 1 are connected by at least two splicing mechanisms. The splicing mechanism includes a splicing body 2 and two plug-in blocks 3. The two plug-in blocks 3 are respectively arranged at both ends of the splicing body 2. The two plug-in blocks 3 are respectively connected between two adjacent display screens 1. Plug-in blocks 4 are fixed at both ends of the splicing body 2. A plug-in hole 5 is provided at one end of the plug-in block 3 close to the splicing body 2. The plug-in block 4 is plugged into the plug-in hole 5. A locking hole 6 is provided on one side wall of the plug-in block 4. A locking block 7 is provided on the inner wall of the plug-in hole 5. The locking block 7 moves along the axial direction of the locking hole 6. The locking block 7 is adapted to be in the locking hole 6. The plug-in block 3 is fixedly connected to the display screen by means of screws. The back of the splicing body 2, or the plug-in block 3 is integrally formed with the back of the display screen 1, first insert the plug-in block 4 at one end of the splicing body 2 into the plug-in hole 5 of the plug-in block 3 on a display screen 1, and then slide the locking block 7 into the locking hole 6 to complete the quick connection between the splicing body 2 and the plug-in block 3, and then connect the plug-in block 3 of the other display screen to the plug-in block 4 at the other end of the splicing body 2, so that the other end of the splicing body 2 and the plug-in block 3 on the display screen 1 complete the cooperation between the plug-in block 4 and the plug-in hole 5, and the cooperation between the locking block 7 and the locking hole 6, so as to realize the quick splicing between the display screens, and facilitate the connection of the corresponding number of LED display screens to form a large screen according to the needs of use, so that there is no need to customize the large screen, and it is convenient to transport, easy to use and assemble at any time, with a wide range of adaptability, and can be used in a variety of occasions.

[0021] Furthermore, if Figures 1 to 3 As shown, the plug-in block 3 is provided with a mounting hole 8 on the side wall of the socket 5, one end of the locking block 7 is slidably adapted in the mounting hole 8, and a spring 9 is arranged in the mounting hole 8, and the two ends of the spring 9 are respectively connected to the locking block 7 and the plug-in block 3. When the spring 9 is in a normal state, the locking block 7 is adapted in the locking hole 6, and the locking block 7 is provided with a wedge surface 10 at one end away from the spring 9, and the wedge surface 10 faces the plug-in block 4. The process of connecting the plug-in block 4 to the plug-in block 3 is as follows: the plug-in block 4 is inserted into the socket 5, and the plug-in block 4 first contacts the wedge surface 10 of the locking block 7. Under the guidance of the wedge surface 10, the locking block 7 squeezes the spring 9 and moves into the mounting hole 8, so that the plug-in block 4 can be fully matched in the socket 5. At this time, the locking hole 6 is located on the moving path of the locking block 7. Under the reaction force of the spring 9, the locking block 7 is automatically inserted into the locking hole 6, so that the plug-in block 4 and the plug-in block 3 are quickly connected, and the operation is simple and fast.

[0022] Furthermore, if Figure 2 and Figure 3As shown, a pull rod 11 is fixed to one end of the locking block 7 connecting the spring 9, and the pull rod 11 movably passes through the plug-in block 3 and is connected to a pull plate. When the two display screens 1 need to be disassembled, a force is applied to the pull plate to lift the pull rod 11 upwards, and the pull rod 11 will drive the locking block 7 to squeeze the spring 9 and move away from the lock hole 6, so that the locking block 7 is separated from the lock hole 6. At this time, the two display screens 1 can be directly removed, so that the quick disassembly between the display screens 1 can be completed.

[0023] Furthermore, if Figures 1 to 4 As shown, the splicing body 2 includes a first hinge plate 12 and a second hinge plate 13, the first hinge plate 12 and the second hinge plate 13 are hinged to each other, and the two plug-in blocks 3 are respectively fixed on the first hinge plate 12 and the second hinge plate 13, and a hollow sleeve 14 is fixed at intervals on the upper and lower sides of the first hinge plate 12 close to the second hinge plate 13, and a hinge shaft 15 is fixed at intervals on the upper and lower sides of the second hinge plate 13 close to the first hinge plate 12, and the hinge shaft 15 is movably adapted in the hollow sleeve 14. Due to different usage scenarios, the splicing between display screens 1 is not limited to plane splicing, and the overall screen is required to present a certain curvature, or the display screens on both sides are tilted toward the center to achieve a better display effect. Therefore, the splicing body 2 adopts a split structure, through the hinge shaft 15 and the hollow The movable cooperation of the sleeve 14 hinges the first hinge plate 12 and the second hinge plate 13 together, so that the first hinge plate 12 and the second hinge plate 13 can deflect relative to each other, thereby adjusting the angle between two adjacent display screens 1 to achieve the effect of splicing into an arc-shaped screen. After the angle adjustment is completed, the display screen is installed on the support frame to maintain the position between the display screens 1 and to provide support. In specific implementation, an elastic friction sleeve is fixedly sleeved on the hinge shaft 15, and the elastic friction sleeve is fitted in the hollow sleeve 14 through its own deformation interference fit, so that a strong friction force is generated between the elastic friction sleeve and the hollow sleeve 14, thereby being able to lock the position between the display screens 1 to a certain extent. To adjust the position between the display screens 1, force needs to be applied to overcome the friction force generated by the elastic friction sleeve.

[0024] Furthermore, if Figure 1 and Figure 4As shown, a first limit block 16 is fixed on the back of the first hinge plate 12, and a second limit block 17 is fixed on the back of the second hinge plate 13. The first limit block 16 and the second limit block 17 are jointly penetrated with a deflection lock rod 18. The second limit block 17 is penetrated with a through hole 19 along the axial direction of the vertical hinge shaft 15. A threaded hole 20 is opened at one end of the first limit block 16 close to the second limit block 17. The deflection lock rod 18 movably passes through the through hole 19 and is threadedly adapted in the threaded hole 20. When the display screens 1 are directly plane-jointed, in order to ensure a better plane-jointing effect, The deflection locking rod 18 is used to lock the deflection freedom between the first hinge plate 12 and the second hinge plate 13, and the first hinge plate 12 and the second hinge plate 13 are in the same plane. Specifically, the threaded end of the deflection locking rod 18 is passed through the through hole 19 and adapted in the threaded hole 20, so that the deflection locking rod 18 is connected to the first limit block 16 and the second limit block 17 at the same time, thereby realizing the connection between the first hinge plate 12 and the second hinge plate 13, and making the first hinge plate 12 and the second hinge plate 13 in the same plane, ensuring that the plane splicing between the display screens 1 has a better effect.
