Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a spliced ​​display screen. Background Art

[0002] The splicing display is a display technology that forms a large-size display screen by splicing multiple LCD screens together. This screen is usually composed of several LCD screens, each of which is called a splicing unit. They are closely connected through a specific frame structure to form a continuous and seamless display surface.

[0003] Before the splicing and installation of the spliced ​​display screen, the insertion frame parts should be installed in the pre-appropriate position. The insertion frame parts are composed of several pre-measured support structures, connectors and bolts. Then, four fixing parts are installed on the back of the spliced ​​display screen through bolts, and then the fixing parts are connected to the connectors on the insertion frame parts one by one. The insertion frame parts make several spliced ​​displays form an integral display surface. However, when several display units are spliced ​​together, gaps will be left between the display screen units horizontally to ensure that the display screens will not be squeezed and broken. Due to the differences in manual splicing operations, gaps of different sizes will inevitably be generated between two adjacent display units, and these gaps need to be adjusted by sliding each display screen unit horizontally. However, when adjusting each display screen unit, multiple workers need to work together. If the appropriate spacing is continuously tried according to the actual situation, after one of the display screens is moved, the other display screens will be adjusted accordingly, thereby increasing the work intensity of the workers and increasing the splicing and installation time of the display screen.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] The utility model embodiment provides a spliced ​​display screen, including at least two display screen bodies 1, and also includes an insertion frame member 2 and a receiving frame plate 113 with an opening on one side. The insertion frame member 2 is connected to the back of the display screen body 1, and the receiving frame plate 113 can be inserted into the insertion frame member 2. The receiving frame plate 113 is connected to the back of the display screen body 1 on a side away from the insertion frame member 2. When in use, the two display screen bodies 1 are docked, and the insertion frame 2 is inserted into the receiving frame 113.

[0028] Preferably, a limit assembly is also included, which is used to limit the moving distance of the inserted frame member 2 after being inserted into the receiving frame plate 113 by adjusting the limit assembly. The limit assembly, in conjunction with the block 9 and the limit toothed strip 8, can fix the position of the inserted frame member 2 so that its position in the receiving frame plate 113 no longer moves, thereby stabilizing the stability between the two display screen bodies 1 and ensuring that the gap between the display screen bodies 1 will not change easily.

[0029] The first implementation method of the limit assembly of the utility model is as follows: Figure 3 As shown in 8, the limiting assembly includes a threaded rod 401 threadedly connected to the receiving frame plate 113, and a resistance block 4011 is fixedly connected to one end of the threaded rod 401. The resistance block 4011 avoids direct contact between the threaded rod 401 and the inserted frame member 2, so that the inserted frame member 2 will not be scratched by the threaded rod 401. By adjusting the length of the threaded rod 401 extending to the inside of the receiving frame plate 113, the gap between the two display screen bodies 1 is controlled. The position of the resistance block 4011 is adjusted by the threaded rod 401. When the inserted frame member 2 is inserted into the receiving frame plate 113, the resistance block 4011 resists against one end of the inserted frame member 2 inserted into the receiving frame plate 113, thereby limiting the position of the inserted frame member 2 inserted into the receiving frame plate 113. At this time, the inserted frame member 2 will no longer continue to penetrate into the receiving frame plate 113.

[0030] The second implementation method of the limit assembly of the utility model is as follows: Figure 6 as well as Figure 7As shown, the limit assembly includes a block 402 with a plurality of slots 4021, and a groove 4022 is provided on the receiving frame plate 113. The block 402 is movably connected in the groove 4022 through the slots 4021. By adjusting the length of one end of the block 402 extending to the inside of the receiving frame plate 113, the gap between the two display screen bodies 1 is controlled. In this process, the plurality of slots 4021 on the block 402 provide a plurality of options for the distance dimension of the block 402 extending to one end inside the receiving frame plate 113. When the slots 4021 at different positions are connected with the grooves 4022, the distance dimension of the block 402 extending to one end inside the receiving frame plate 113 is different. When the block 402 contacts the inserted frame member 2, the end faces of both ends of the block 402 are flat, ensuring that the block 402 can contact the inserted frame member 2 smoothly and protecting the contact surfaces of the two.

[0031] Preferably, a movable plate 7 is slidably connected to the insertion frame member 2, and movable plates 7 are slidably connected to both ends of the insertion frame member 2. When in use, the insertion frame member 2 and the receiving frame plate 113 are first fixedly installed on the back of the display screen body 1, and then the display screen body 1 is installed one by one on the connecting member on the supporting structure through the fixing members, wherein the fixing members, the supporting structure and the connecting members are all features of the prior art.

[0032] When the insertion frame member 2 and the receiving frame plate 113 are fixedly installed, both are first installed on the back of the same display screen body 1 and located on both sides respectively. In order to ensure smooth insertion between the insertion frame member 2 and the receiving frame plate 113, the installation positions of the insertion frame members 2 and the receiving frame plates 113 on the two adjacent display screen bodies 1 should correspond to each other, that is, the insertion frame member 2 on one display screen body 1 is opposite to the receiving frame plate 113 on the other display screen body 1, or the receiving frame plate 113 on one display screen body 1 is opposite to the insertion frame member 2 on the other display screen body 1. As the two display screen bodies 1 are docked, the insertion frame member 2 can be inserted into the receiving frame plate 113.

[0033] Among them, the limited toothed strips 8 are fixedly connected to the opposite inner side walls of the receiving frame plate 113, and the movable plate 7 is slidably connected with a clamping block 9, and the clamping block 9 is connected to the movable plate 7 by a spring 10. When the inserted frame member 2 is inserted into the receiving frame plate 113, the teeth with inclined surfaces on the limited toothed strip 8 will continuously squeeze and clamp one end of the clamping block 9. Specifically, when the inserted frame member 2 is stationary, the clamping block 9 will be clamped at the position between two adjacent teeth on the limited toothed strip 8. When the inserted frame member 2 continues to move in the moving direction when entering the receiving frame plate 113, because the inclined surface of the teeth on the limited toothed strip 8 is toward the insertion direction of the inserted frame member 2, the clamping block 9 will be clamped at the position between the two adjacent teeth on the limited toothed strip 8. In the insertion direction, when the insertion frame member 2 moves, the inclined surface of the teeth on the limiting toothed strip 8 will squeeze the end surface of the block 9, and the block 9 will continue to slide in the direction of the movable plate 7 after being squeezed, and then squeeze the spring 10 connected to the other end of the block 9, until the end surface of the block 9 passes over the inclined surface of the teeth. The block 9 will move in the opposite direction under the action of the elastic force released by the spring 10, that is, the block 9 will be clamped on the limiting toothed strip 8 again, and when the block 9 is clamped on the limiting toothed strip 8, the insertion frame member 2 can be fixed in one direction, that is, the insertion frame member 2 at this time can only move in one direction on the receiving frame plate 113.

[0034] Preferably, a double-headed threaded rod 12 is rotatably connected to the insertion frame member 2, and a U-shaped frame plate 11 is fixedly connected to the movable plate 7. The double-headed threaded rod 12 is threadedly connected to the frame plate 11. When the insertion frame member 2 needs to be removed from the receiving frame plate 113, it is only necessary to rotate the double-headed threaded rod 12, thereby driving the two movable plates 7 threadedly connected to the two ends of the double-headed threaded rod 12 to move in relative or opposite directions. When the two movable plates 7 move in relative directions, the block 9 will disengage from the limiting toothed strip 8 driven by the movable plates 7. After the block 9 is completely disengaged from the limiting toothed strip 8, the insertion frame member 2 can be removed from the receiving frame plate 113, so that the gap between the two display screen bodies 1 can be freely adjusted in distance.

[0035] Among them, Figure 4 as well as Figure 5As shown, the insertion frame member 2 is plugged into one end of the receiving frame plate 113 and is fixedly connected with a half-circle plate 5, and a pin block 6 that is movably engaged with the half-circle plate 5 is fixedly connected on a side wall of the receiving frame plate 113 close to the insertion frame member 2. When the insertion frame member 2 is inserted into the receiving frame plate 113, in order to ensure stability during the insertion process and to facilitate the stabilization of the upper and lower height relationship of the two display screen bodies 1, the half-circle plate 5 will be connected with the pin block 6 after the insertion frame member 2 is inserted into the receiving frame plate 113 for a certain distance, and the pin block 6 will slide into the half-circle plate 5. At this time, the half-circle plate 5 plays a limiting and guiding role for the pin block 6, so that the insertion of the insertion frame member 2 into the receiving frame plate 113 is more stable and the relative position between the two will not produce a large deviation.
