Description

Technical Field

[0001] The utility model relates to the technical field of connection components and combined display screens, in particular to a connection mechanism and a modular display screen using the same. Background Art

[0002] Due to the limited specifications of a single screen, multiple module screens are usually spliced ​​and combined in concerts or various exhibitions to obtain a larger display screen. Subsequently, the display image of each module screen display information can be controlled to obtain a full-screen display effect. The combination of the above-mentioned module screens needs to ensure alignment and stability to avoid safety problems or poor display effects. The existing connection structure generally uses a construction frame to install the module screen. When installing the module screen, the constructed frame needs to set connectors according to needs. In addition, since the frame lacks a reference structure, it is necessary to plan the position of the module screen and set the connection structure during installation. The process is cumbersome and easily leads to poor combination effect between the module screens, and the best experience cannot be obtained. Utility Model Content

[0003] In order to solve the above-mentioned problem of lack of a connection structure dedicated to a module screen, the utility model provides a connection mechanism and a modular display screen using the same.

[0004] The technical solution of this utility model is as follows:

[0005] A connecting mechanism, comprising:

[0006] A reference bottom plate, which is rectangular and has a flat upper surface and is provided with an insert block;

[0007] A reference frame is arranged on the reference base plate, and the reference frame includes a cube frame, and the side length of the cube frame is the same as the width of the reference base plate, the cube frame is circumferentially provided with plug blocks and slots, and the plug blocks and the slots are arranged oppositely, and the cube frame is provided with a mounting sleeve along the length direction of the reference base plate, and the mounting sleeve does not extend outward relative to the cube frame;

[0008] The plug-in frame comprises a positioning plate and a hollow plug-in shaft arranged perpendicular to the positioning plate, and the hollow plug-in shaft is arranged opposite to the installation sleeve.

[0009] Different from the existing structure, the connection structure of the present device includes a plurality of components that can be freely arranged, and each component can be installed according to actual needs. Therefore, the combined structure is more flexible and can be applied to various application scenarios.

[0010] In order to improve the stability after connection, two groups of plugs and slots are arranged around the cube frame, so as to avoid the cube frame from tilting in both horizontal and vertical directions.

[0011] For stability considerations, the length of the reference base plate is greater than the side length of the cube frame. After the reference frame is installed on the reference base plate, the reference base plate can have an extension section for the installation of other parts.

[0012] As a preferred solution, the plugging direction between the plug block and the slot is parallel to the length direction of the reference base plate.

[0013] In order to position the reference frame, the reference base plate is detachably provided with a limit column, and the distance between the limit column and the farthest edge of the reference base plate is the same as the side length of the cube frame. After the limit column is provided and the reference frame is plugged and installed, the reference frame and the limit column can reach the corresponding position and the positioning is completed, so that three faces of the cube frame are aligned with the reference base plate in the vertical direction.

[0014] The installation method of the above-mentioned limiting column is that the reference bottom plate is provided with a limiting hole, one end of the limiting column close to the limiting hole is provided with a stud, and the end of the limiting column away from the stud is provided with a connecting hole.

[0015] The specific structure of the above-mentioned connecting hole is that the connecting hole includes a hollow thread segment corresponding to the stud, the side of the hollow thread segment away from the stud is a regular hexagonal prism segment, and the hollow thread segment and the regular hexagonal prism segment are coaxially arranged. By adopting the above-mentioned structure, the limit column can be installed through the regular hexagonal prism, and multiple limit columns can also be stacked.

[0016] The structure for fixing the reference base plate is that the reference base plate is provided with a plurality of mounting holes and can be fixed to the reference plane by bolts.

[0017] A modular display screen includes a plurality of square module screens, the module screens are respectively fixed on a plurality of connection mechanisms, and the module screens are detachably connected to a positioning plate, the side length of the module screens is the same as the side length of a cube frame, and a plurality of the connection mechanisms are arranged in a horizontal direction. After the above connection structure is constructed, the module screens can be installed, and then spliced ​​to obtain an overall large screen.

[0018] The method of stacking the module screens in the vertical direction is that a plurality of reference frames on a single reference base plate are arranged in the vertical direction, and a plurality of module screens are arranged in the vertical direction on each reference frame through a plug-in frame.

[0019] The beneficial effect of the utility model is that the utility model is a connection mechanism and a modular display screen using the same, which is different from the existing free frame construction method. The connection mechanism of the device includes multiple assemblies, wherein the reference base plate can be fixed on the reference plane for stable connection, and then, by arranging and setting multiple reference base plates, multiple reference frames can be installed in the horizontal direction, and multiple reference frames can be stacked on top of each reference frame. Therefore, multiple reference frames can be arranged in the vertical and horizontal directions in the above manner, and the above reference frames can independently set plug-in frames, and after the module screen is set by the plug-in frame, the combination screen can be built, and the structure is stable, and the connection between adjacent module screens is compact, and the display effect is better. Finally, by setting the limit column, the position of the reference frame can be limited so that the module screen is located in the same vertical plane to avoid the misalignment problem.

[0033] like Figure 2 A connection mechanism shown includes a reference base plate 2, which is rectangular and has a flat upper surface and is provided with an insert block 13; the structure for fixing the reference base plate 2 is that the reference base plate 2 is provided with a plurality of mounting holes 22, and can be fixed to the reference plane by bolts. Before building the combined screen, the reference base plate 2 needs to be fixed to the reference plane in advance, and the reference plane can be a base plate or the ground or other frame structures, etc. It should be noted that it must be in a horizontal state to avoid the problem of tilting and tipping, and the number of reference base plates 2 can be arranged in multiples to ensure that multiple module screens 5 can be installed in the horizontal direction, and after understanding the specific specifications of the combined screen, the number of module screens 5 in the horizontal direction can be determined, and correspondingly, the corresponding number of reference base plates 2 can be set.

[0034] After completing the construction of the above-mentioned reference base plate 2, you can set up Figure 4 , 5 The reference frame 1 shown is arranged on the reference base plate 2, and the connection method is a detachable connection. Since the method of fixing by bolts is relatively cumbersome, plug-in fixing can be selected. For this purpose, the specific design is that first, the reference frame 1 includes a cube frame 11, and the above-mentioned cube 11 is set corresponding to the specifications of the module screen 5 to ensure that it is more compact during installation. At the same time, the side length of the cube frame 11 is the same as the width of the reference base plate 2. Therefore, after being set and fixed according to the reference base plate 2, it can be ensured that each reference frame 1 is closely arranged, thereby ensuring the close arrangement of the subsequent module screens 5. In order to connect the cube frames 11 with each other and with the reference base plate 2, the cube frame 11 is circumferentially provided with plug blocks 13 and slots 12, and the plug blocks 13 and the slots 12 are arranged relative to each other, as shown in FIG. Figure 3 As shown, the reference frame 1 can be arranged in the vertical and horizontal directions, and the cube frame 11 is provided with a mounting sleeve 14 along the length direction of the reference base plate 2, and the mounting sleeve 14 does not extend outward relative to the cube frame 11. The mounting sleeve 14 is used to install the module screen 5, which will be introduced in detail later. As for the structure of the reference frame 1, since it needs to be built to a higher position and the module screen 5 structure needs to be set, stability design is required.

[0035] like Figure 4As shown, in order to improve the stability after connection, the cube frame 11 is provided with two sets of plug blocks 13 and slots 12 in the circumference. This can prevent the cube frame 11 from tilting in both horizontal and vertical directions. Figure 3 As shown, each structure can be connected to each other, thereby achieving higher stability.

[0036] Furthermore, for stability considerations, the length of the reference base plate 2 is greater than the side length of the cube frame 11. After the reference frame 1 is installed on the reference base plate 2, the reference base plate 2 can have an extension section for the installation of other parts. The reference base plate 2 is equivalent to a base. The larger the base, the better the stability. However, if the reference base plate 2 is too large, it will occupy more space. Therefore, in general, it is only necessary to extend the length, and increasing its width will affect the spacing between the reference frames 1. Accordingly, through the above design, the plug-in method adopted can be that the plug-in direction of the plug-in block 13 and the slot 12 is parallel to the length direction of the reference base plate 2.

[0037] And for the above structure, further, in order to position the reference frame 1, the reference base plate 2 can be detachably provided with a limiting column 4, such as Figure 8 , 9 The distance between the limit column 4 and the farthest edge of the reference base plate 2 is the same as the side length of the cube frame 11. After the limit column 4 is set and the reference frame 1 is installed, the reference frame 1 and the limit column 4 will collide to reach the corresponding position and complete the positioning, so that the cube frame has three faces aligned with the reference base plate 2 in the vertical direction. Figure 2 , 6 As shown, after the three surfaces are aligned, it can ensure that the subsequent installation plane of the module screen 5 is the same vertical plane, so the display effect is better and the installation is more convenient.

[0038] And for the above-mentioned limiting column 4, in order to avoid it affecting the installation of other structures, the installation method adopted is that the reference bottom plate 2 is provided with a limiting hole 23, the limiting column 4 is provided with a stud 42 at one end close to the limiting hole 23, and the limiting column 4 is provided with a connecting hole 41 at one end away from the stud 42. And the height of a single limiting column 4 corresponds to the side length of the reference frame 1, so it can cooperate with the combination of the reference frame 1 to stack and combine the structures. For this reason, the limiting column 4 needs to be set as a structure that can be arranged and combined along the length direction.

[0039] To this end, the specific structure of the connecting hole 41 is that the connecting hole 41 includes a hollow threaded section corresponding to the stud 42, and the side of the hollow threaded section away from the stud 42 is a regular hexagonal prism section, and the hollow threaded section and the regular hexagonal prism section are coaxially arranged. By adopting the above structure, the limit column 4 can be installed through the regular hexagonal prism, and multiple limit columns 4 can also be stacked.

[0040] After completing the above structure, in order to install the module screen 5, it is also necessary to set the following Figure 7 The plug-in frame 3 shown in the figure comprises a positioning plate 32 and a hollow plug-in shaft 31 arranged perpendicular to the positioning plate 32, and the hollow plug-in shaft 31 is arranged opposite to the mounting sleeve 14. Generally, the positioning plate 32 is also arranged in a square shape, and the side length corresponds to the cube frame 11 and the side length of the module screen 5, so that the connection is more compact, and the hollow plug-in shaft 31 and the mounting sleeve 14 are both located in the center, which is convenient for positioning and installation.

[0041] After that, you can achieve Figure 1 The effect shown is shown, and the above-mentioned modular display screen includes a plurality of square module screens 5, the module screens 5 are respectively fixed on a plurality of connection mechanisms, and the module screens 5 are detachably connected to the positioning plate 32, the side length of the module screen 5 is the same as the side length of the cube frame 11, and the plurality of connection mechanisms are arranged in a horizontal direction. After the above-mentioned connection structure is built, the module screens 5 can be installed, and then they can be spliced ​​to obtain an overall large screen.

[0042] The above method can only be used for arrangement and installation in the horizontal direction. In order to achieve arrangement and installation in the vertical direction, multiple reference frames 1 on the single reference base plate 2 are arranged in the vertical direction, and multiple module screens 5 are arranged in the vertical direction, and are respectively arranged on each reference frame 1 through the plug-in frame 3. By adopting the above method, the module screens 5 arranged in the horizontal and vertical directions can be obtained, and Figure 1 Normal use.

[0043] Moreover, the above-mentioned connection structure is different from the existing structure. The connection structure of the present device includes a plurality of components that can be freely set, and each component can be installed according to actual needs. Therefore, the combined structure is more flexible and can be suitable for various application scenarios. In other words, the number of module screens 5 in the horizontal and vertical directions can be freely defined and meet the needs.
