Description

Technical Field

[0001] This utility model relates to the field of splicing screen technology, and in particular to a design effect splicing large screen display device. Background Technology

[0002] A video wall is a large-size display system composed of multiple display units. Through modular design, it achieves seamless or narrow-bezel high-resolution images and supports various display modes such as full-screen, split-screen, and picture-in-picture. The main types include LCD video walls, LED video walls, and DLP video walls, and they are widely used in command and control, conference presentations, advertising media, security monitoring, and other fields.

[0003] 1. With the increasing diversity of application scenarios, existing straight-screen splicing large screens cannot fully cope with a variety of different usage scenarios. If a custom-made connecting frame is made according to the curvature between the screens, it will increase the installation cost for different scenarios. Moreover, the custom-made connecting frame is limited in scope and cannot fully adapt to different bending scenarios.

[0004] 2. During use, individual video walls generate heat over time. When multiple video walls generate heat together, the rate of temperature increase accelerates. If the video wall gets too hot, it will first affect its functionality, and secondly, excessive heat can also become a fire hazard, causing inconvenience to the use of the video wall.

[0030] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0031] Reference Figure 1-6 This utility model embodiment discloses a design effect splicing large screen display device, which includes a splicing screen 1, a connecting device 2, a support frame 3, a fixing frame 4, a connecting frame 5, a rotating frame 6, and a heat dissipation device 7. The connecting device 2 includes a frame 21 and a knob 22. The right side of the knob 22 has a hexagonal slot 23, and the left side of the knob 22 is fixedly connected to a bidirectional lead screw 24. The left and right sides of the bidirectional lead screw 24 are threadedly connected to sliders 25. The middle of the slider 25 is fixedly connected to a locking block 26. The inside of the frame 21 is fixedly connected to a limit rod 27.

[0032] In the above structure, rotating the knob 22 causes the bidirectional lead screw 24 to rotate. Slider 25s are threaded onto the left and right sides of the bidirectional lead screw 24, causing the lead screw 24 to drive the sliders 25s on both sides to move synchronously towards the center or in opposite directions. The locking block 26 corresponds to the locking hole 33, so that when the sliders 25s on both sides move synchronously towards the center, the locking block 26 moves synchronously towards the center. As the locking block 26 moves, it enters the locking hole 33, completing the installation of the splicing screen 1.

[0033] The knob 22 has a hexagonal slot 23 on its right side, which allows installers to install the splicing screen 1 using an electric gun with an internal hexagonal head, thus enabling a faster installation process.

[0034] The support frame 3 includes a first frame 31, a first opening 32 is provided through the surface of the first frame 31, a lock hole 33 is provided through the middle of the first frame 31, the frame 21 is fixedly connected to the splicing screen 1, the bidirectional screw 24 is rotatably connected to the frame 21, the slider 25 is slidably connected to the limiting rod 27, and the locking block 26 corresponds to the lock hole 33.

[0035] The above structure, by setting a slider 25 and a limiting rod 27 to slide together, and the limiting rod 27 to be fixedly connected to the frame 21, allows the limiting rod 27 to limit the slider 25, so that the slider 25 can move left and right stably.

[0036] The fixing frame 4 includes a second frame 41. A first slot 42 is symmetrically provided in the middle of the second frame 41. A second opening 43 is provided through the front and rear sides of the second frame 41. A second opening 43 is provided through the rear right side of the second frame 41. The front second opening 43 corresponds to the first opening 32. The first slot 42 corresponds to the first frame 31.

[0037] The above structure, through the correspondence between the first slot 42 and the first frame 31, allows the operator to install the two fixing frames 4 on both sides of a single support frame 3 respectively, that is, insert the first frame 31 into the interior of the first slot 42, and ensure that the protruding blocks at the rear of the fixing frames 4 face the same direction, and thus perform array-type installation to complete the construction of the main frame of the splicing large screen, and the left and right sides of the main frame are finished by the support frames 3, which facilitates the subsequent installation of the rotating frame 6.

[0038] The second opening 43 corresponds to the first opening 32, allowing the operator to connect the support frame 3 and the fixed frame 4 using external bolts and nuts after the connection is complete. Furthermore, the protruding block at the rear of the second frame 41 also corresponds to the first slot 42, enabling the operator to assemble the two fixed frames 4 according to the actual usage scenario. This accommodates right-angle connections and better addresses longitudinal extensions. Both are also connected and secured using external bolts and nuts.

[0039] The connecting frame 5 includes a third frame 51. The third frame 51 has a second slot 52 symmetrically opened in the middle. The third frame 51 has a third opening 53 through the front and rear sides. The second slot 52 corresponds to the rear of the second frame 41, and the third opening 53 corresponds to the rear second opening 43.

[0040] The above structure has a second slot 52 symmetrically opened in the middle of the third frame 51, and the second slot 52 corresponds to the protruding block at the rear of the fixed frame 4. This allows the operator to use the connecting frame 5 to complete the installation between two different fixed frames 4. In this process, the connecting frame 5 is misaligned with the fixed frame 4, so that a single connecting frame 5 can install four fixed frames 4, thereby realizing the vertical extension of the fixed frame 4 upward or downward.

[0041] Through the mutual assembly and combination of multiple support frames 3, fixing frames 4, and connecting frames 5, it is possible to assemble them into a form such as Figure 2 The sun-shaped structure, through its function, gives the main frame a certain vertical depth. This inward vertical extension allows the main frame to stand stably on the working surface. Furthermore, it can be assembled multiple times to achieve greater depth, adapting to the actual height and width of the overall frame, thus providing better support for the main frame.

[0042] The third opening 53 corresponds to the second opening 43 at the rear, allowing the operator to connect and fix the fixing frame 4 and the connecting frame 5 using external bolts and nuts.

[0043] The rotating frame 6 includes a first rotating frame 61, a fixing block 62 fixedly connected to the lower part of the first rotating frame 61, a connecting rod 63 fixedly connected to the lower part of the fixing block 62, a rotating block 64 rotatably connected to the upper part of the connecting rod 63, a locking block 65 threadedly connected to the upper end of the connecting rod 63, a locking spring 66 fixedly connected to the lower part of the locking block 65, the other end of the locking spring 66 in close contact with the rotating block 64, a second rotating frame 67 fixedly connected to the left side of the rotating block 64, a third slot 68 opened in the middle of the first rotating frame 61, a third slot 68 opened in the middle of the second rotating frame 67, a fourth opening 69 penetrating through the front and rear sides of the first rotating frame 61, and a fourth opening 69 penetrating through the front and rear sides of the second rotating frame 67, the third slot 68 corresponding to the first frame 31, and the fourth opening 69 corresponding to the first opening 32.

[0044] The above structure, with the third slot 68 corresponding to the first frame 31 and the fourth hole 69 corresponding to the first hole 32, allows a single rotating frame 6 to connect two support frames 3. That is, the two are connected and fixed by external bolts and nuts at the fourth hole 69 and the first hole 32. A single rotating frame 6 can connect and install two support frames 3. The first rotating frame 61 and the second rotating frame 67 in the rotating frame 6 rotate relative to each other, so that the operator can connect the two support frames 3 and then adjust the angle between the two support frames 3, thereby realizing the adjustment of the angle between the two splicing screens 1.

[0045] A locking block 65 is threadedly connected to the upper end of the connecting rod 63. A locking spring 66 is fixedly connected to the lower part of the locking block 65. The other end of the locking spring 66 is in close contact with the rotating block 64. By rotating the locking block 65, the operator can bring it closer to the rotating block 64. At this time, the locking spring 66 is compressed. When the locking block 65 and the rotating block 64 are in close contact, the locking spring 66 is compressed to its maximum. At this time, the relative elastic force applied by the locking spring 66 to the rotating block 64 and the compression of the locking block 65 to the rotating block 64 make the rotating block 64 and the fixed block 62 in close contact under pressure. Under the action of the compression force, the rotating block 64 and the fixed block 62 are in a relatively stationary state that makes it difficult for them to rotate. After the adjustment is completed, the two support frames 3 are relatively locked, making it difficult for them to rotate easily.

[0046] The heat dissipation device 7 includes a heat dissipation fan 71. A connecting block 72 is fixedly connected to the left side of the heat dissipation fan 71. A docking block 73 is rotatably connected to the left side of the connecting block 72. A fifth opening 74 is provided through the upper and lower sides of the docking block 73. The fifth opening 74 corresponds to the second opening 43. The docking block 73 corresponds to the first slot 42.

[0047] The above structure includes a docking block 73 with a fifth opening 74 through the upper and lower sides of the docking block 73, which corresponds to the second opening 43. The docking block 73 corresponds to the first slot 42, allowing the operator to install the heat dissipation device 7 onto the top of the fixing frame 4 using external bolts and nuts.

[0048] The connecting block 72 is rotatably connected to the docking block 73, so that when the operator installs the heat dissipation device 7 on the top of the fixed frame 4, the blowing direction of the heat dissipation fan 71 can be adjusted. The direction of the air blowing of the heat dissipation fan 71 can be adjusted according to the actual situation. The limit rotation angle between the heat dissipation fan 71 and the docking block 73 is large, which makes it convenient for the operator to adjust.

[0049] Working principle: When using this type of splicing large screen display device, firstly, according to the actual usage scenario, assemble the support frame 3, fixing frame 4, connecting frame 5, rotating frame 6, and heat dissipation device 7. After assembly, place the entire device on a relatively flat ground in the usage scenario, and use conventional techniques for splicing screens, such as sandbags, ropes, and other external items to tie and fix the frame, so that the frame can stand stably on the ground. Then, the operator installs the splicing screen 1 from one direction, that is, completes the docking between multiple sets of connecting devices 2 and support frame 3. After installation, turn on the cooling fan 71 to use the splicing screen 1.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
