Description

Technical Field

[0001] This application relates to the field of screen splicing technology, and in particular to a splicing screen system that can be quickly assembled and disassembled. Background Technology

[0002] Currently, the display area of ​​a single display screen is relatively small. In order to display larger images, splicing screen technology has emerged. This splicing screen is formed by splicing multiple screen bodies together. Each screen body displays a part of an image. The screen bodies arranged in a matrix can jointly display a very large image. It is often used in security, monitoring, medical, broadcasting and television, advertising and media and other fields.

[0003] In one related technology, multiple screen units are clipped onto a mounting base to form a splicing screen in pursuit of installation efficiency. This installation method has poor stability, especially for places where such splicing screens need to be set up for a long time, as there is a high risk that a single screen unit will detach from the mounting base.

[0004] Another related technology prioritizes installation stability by fixing each screen unit to the mounting base using a threaded mounting structure to form a splicing screen. However, this installation method is time-consuming and labor-intensive to install and remove.

[0005] Therefore, how to balance installation efficiency and stability, and achieve rapid assembly and disassembly of multiple screen bodies and mounting bases to form a splicing screen, is a technical problem that urgently needs to be solved. Summary of the Invention

[0006] This application aims to at least address the technical problems existing in the prior art that fail to adequately balance installation efficiency and stability, and to achieve rapid assembly and disassembly of multiple screen bodies and mounting bases to form a video wall. To this end, this application proposes a video wall system for rapid assembly and disassembly.

[0007] This application provides a quick-assembly and disassembly splicing screen system, including:

[0008] Mounting base, wherein support blocks are spaced apart on the mounting base, and limit rods are elastically installed inside the side wall of the support blocks;

[0009] Multiple screen bodies, with the sidewalls of every two adjacent screen bodies abutting and pressing against the spaced-apart support blocks, and a limit block installed on the back of each screen body, with a limit hole through the limit block aligned with the limit rod, and an air cavity formed between the screen body and the spaced-apart support blocks;

[0010] An air extraction device is installed on the mounting base, the air extraction end of the air extraction device is connected to the air chamber, and is adapted to move a portion of the limiting rod into the limiting hole.

[0011] By adopting the above technical solution, the air pressure in the air chamber can be switched between negative pressure and normal pressure by using an air extraction device. This allows the limiting rod to extend elastically and insert into the limiting hole to constrain and fix the screen body, or to retract elastically into the support block to cancel the constraint and fixation of the screen body, thus taking into account both installation efficiency and installation stability.

[0012] According to one embodiment of this application, the back of the screen body is provided with a card slot, and the card slot is fitted and fixed to one end of the limiting block away from the mounting base.

[0013] By adopting the above technical solution, the installation of the two can be quickly achieved by fitting and fixing the limiting block with the slot of the screen body. In other words, when it is necessary to make a splicing screen system, the limiting block and the slot of the screen body are fitted and fixed. When it is not necessary to make a splicing screen system, the limiting block and the slot of the screen body are disassembled and separated, thereby making the screen body more adaptable.

[0014] According to one embodiment of this application, there are two card slots, and the limiting blocks are correspondingly fitted into the two card slots, with the wall surface of the limiting block abutting against the corresponding support block.

[0015] By adopting the above technical solution and increasing the number of limiting blocks, the volume of the air chamber is reduced, making it easier for the air chamber to be in a negative pressure state.

[0016] According to one embodiment of this application, the mounting base is provided with a positioning block, and the limiting block is provided between the positioning block and the support block, wherein the height of the positioning block is lower than the limiting hole.

[0017] By adopting the above technical solution, a positioning block is fixedly connected to the mounting base, and a limiting block is provided between the positioning block and the support block. The height of the positioning block is lower than the limiting hole.

[0018] According to one embodiment of this application, the number of air chambers is multiple, and the mounting base is provided with an air extraction channel. The air extraction channel has a first air port and multiple second air ports. The first air port is connected to the air extraction end of the air extraction device, and the second air ports are connected to the air chambers respectively.

[0019] By adopting the above technical solution, the gas in multiple air chambers can flow from their corresponding second air ports through the extraction channel and then from the first air port into the extraction end of the extraction device. In other words, this example can adjust the gas pressure in multiple air chambers with one extraction device.

[0020] According to one embodiment of this application, a compressed sealing gasket is provided between the support block and the screen body.

[0021] By adopting the above technical solution, this design can prevent ambient gas from entering the air cavity from the area between the support block and the screen body when the air pressure in the air cavity is negative, thus preventing the negative pressure state from failing.

[0022] According to one embodiment of this application, a sealing strip is provided for airtight connection between two adjacent screen bodies, and the sealing strip is located within the air cavity.

[0023] By adopting the above technical solution, this design can prevent ambient gas from entering the air cavity from the area between two adjacent screen bodies when the air pressure in the air cavity is in a negative pressure state, thus preventing the negative pressure state from failing.

[0024] According to one embodiment of this application, the mounting base has a slot, and multiple screen bodies abut against each other to form a splicing screen, with the splicing screen pressed against the slot.

[0025] By adopting the above technical solution, on the one hand, when the air pressure in the air cavity is in a negative pressure state, it can prevent ambient gas from entering the air cavity from the area between the groove wall of the mounting base and the splicing screen, thus preventing the negative pressure state from failing. On the other hand, it also makes the overall splicing screen system more aesthetically pleasing.

[0026] According to one embodiment of this application, the support block has a mounting hole in its side wall, one end of the limiting rod is circumferentially fixed with a retaining ring and disposed in the mounting hole, a spring is sandwiched between the retaining ring and the wall of the mounting hole, and the other end of the limiting rod can move into the limiting hole.

[0027] By adopting the above technical solution, after the air chamber forms a negative pressure state, a pressure difference will be formed on the side of the retaining ring close to the air chamber and the side of the retaining ring away from the air chamber, thereby compressing the retaining ring spring, and the other end of the limiting rod can elastically extend out of the mounting hole until it is inserted into the limiting hole.

[0028] According to one embodiment of this application, the suction end of the suction device is connected to the air chamber via a multi-way valve.

[0029] By adopting the above technical solution, the air pumping end of the air pumping device can be switched to be connected to the first air port, or the first air port can be switched to be connected to the ambient gas, thereby adjusting the air pressure in the air chamber to negative pressure or restoring it to normal pressure.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The splicing screen system provided in this application embodiment switches the air pressure in the air chamber between negative pressure and normal pressure through the air extraction device, so that the limiting rod can be elastically extended and inserted into the limiting hole to constrain and fix the screen body, or elastically retracted into the support block to cancel the constraint and fixation of the screen body, thereby taking into account both installation efficiency and installation stability.

[0032] 2. After the air chamber forms a negative pressure state, a pressure difference will be formed on the side of the retaining ring close to the air chamber and the side of the retaining ring away from the air chamber, thereby compressing the retaining ring spring, and the other end of the limiting rod can elastically extend out of the mounting hole until it is inserted into the limiting hole.

[0033] 3. By engaging and fixing the limiting block with the slot of the screen body, the installation of the two can be quickly achieved. In other words, when a splicing screen system needs to be made, the limiting block and the slot of the screen body are engaged and fixed. When a splicing screen system does not need to be made, the limiting block and the slot of the screen body are disassembled and separated, thereby making the screen body more adaptable.

[0045] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0046] The following is for reference. Figures 1-6 This application describes a splicing screen system that can be quickly assembled and disassembled according to an embodiment of the present application.

[0047] like Figure 1 As shown, the quick-assembly and disassembly splicing screen system includes: a mounting base 100, multiple screen bodies 200, and an air extraction device 300.

[0048] like Figure 2 and Figure 3 As shown, the mounting base 100 is provided with support blocks 110 at intervals, and the side wall of the support block 110 is elastically installed with limit rods 120.

[0049] The sidewalls of each pair of adjacent screen bodies 200 abut against each other and are pressed against the spaced support blocks 110. Each screen body 200 has a limit block 210 installed on its back side. The limit block 210 has a limit hole 211 that is aligned with the limit rod 120. The screen body 200 and the spaced support blocks 110 enclose each other to form an air cavity a.

[0050] like Figure 2 and Figure 4 As shown, the air extraction device 300 is installed on the mounting base 100. The air extraction end of the air extraction device 300 is connected to the air chamber a and is adapted to move a portion of the limiting rod 120 into the limiting hole 211.

[0051] Specifically, the sidewalls of every two adjacent screen bodies 200 abut against each other and press against the spaced-apart support blocks 110, which can form an air cavity a between the screen body 200, the spaced-apart support blocks 110 and the mounting base 100. The suction end of the suction device 300 extracts the gas in the air cavity a, which can make the air cavity a negative pressure state. During this process, the limiting rod 120 in the support block 110 will extend elastically and insert into the limiting hole 211 to complete the constraint and fixation of each screen body 200.

[0052] Conversely, when removing the screen body 200 from the mounting base 100, simply introduce ambient gas into the air chamber a to restore the air pressure inside the air chamber a. During this process, the limiting rod 120 will elastically retract into the support block 110, thereby releasing the constraint and fixation on each screen body 200.

[0053] In the above embodiments of this application, after the air cavity a forms a negative pressure state, it can adsorb the screen body 200 onto the spaced support blocks 110. At the same time, the limiting rod 120 in the support block 110 extends elastically and inserts into the limiting hole 211, which can further constrain and fix the screen body 200, thereby improving the stability of the entire splicing screen system. After the air cavity a returns to normal pressure, the limiting rod 120 will retract elastically into the support block 110, canceling the constraint and fixation on each screen body 200, making it easy for engineers to remove multiple screen bodies 200 from the mounting base 100.

[0054] In summary, the splicing screen system provided in this application embodiment can switch the air pressure of the air chamber a between negative pressure and normal pressure by using the air extraction device 300. This allows the limiting rod 120 to extend elastically and insert into the limiting hole 211 to constrain and fix the screen body 200, or to retract elastically into the support block 110 to cancel the constraint and fixation of the screen body 200, thereby taking into account both installation efficiency and installation stability.

[0055] like Figure 3 As shown, in some embodiments, a positioning block 130 is fixedly connected to the mounting base 100, and a limiting block 210 is provided between the positioning block 130 and the support block 110. The height of the positioning block 130 is lower than the limiting hole 211.

[0056] In this embodiment, the limiting block 210 of the screen body 200 is inserted between the positioning block 130 and the support block 110, which can limit the limiting block 210 of the screen body 200, thereby aligning the limiting hole 211 of the limiting block 210 with the limiting rod 120 of the support block 110.

[0057] like Figure 3 and Figure 4 As shown, in some embodiments, the support block 110 has a mounting hole 111 in the side wall, one end of the limiting rod 120 is circumferentially fixed with a retaining ring 121 and is disposed in the mounting hole 111, a spring 140 is sandwiched between the retaining ring 121 and the wall of the mounting hole 111, and the other end of the limiting rod 120 can move into the limiting hole 211.

[0058] In this embodiment, after the air chamber a forms a negative pressure state, a pressure difference will be formed on the side of the retaining ring 121 close to the air chamber a and the side of the retaining ring 121 away from the air chamber a, so that the retaining ring 121 compresses the spring 140, and the other end of the limiting rod 120 can elastically extend out of the mounting hole 111 until it is inserted into the limiting hole 211.

[0059] In actual operation, a soft rubber layer is fixed to the peripheral wall of the retaining ring 121, and the soft rubber layer is compressed and placed between the peripheral wall of the retaining ring 121 and the peripheral wall of the mounting hole 111.

[0060] In actual implementation, the peripheral wall of the mounting hole 111 is formed with a flange, which is located inside the mounting hole 111 and a spring 140 is sandwiched between it and the retaining ring 121.

[0061] like Figure 5 As shown, in some embodiments, the back of the screen body 200 is provided with a card slot 220, which is engaged and fixed with the end of the limiting block 210 away from the mounting base 100.

[0062] In this embodiment, the installation of the two can be quickly achieved by fitting and fixing the limiting block 210 with the slot 220 of the screen body 200. In other words, when it is necessary to make a splicing screen system, the limiting block 210 is fitted and fixed with the slot 220 of the screen body 200. When it is not necessary to make a splicing screen system, the limiting block 210 is disassembled and separated from the slot 220 of the screen body 200, thereby making the screen body 200 more adaptable.

[0063] like Figure 5 As shown, for example, there are two card slots 220, and corresponding limiting blocks 210 are fitted into the two card slots 220. The wall surface of the limiting block 210 is in contact with the corresponding support block 110.

[0064] In this example, by increasing the number of limiting blocks 210, the volume of air chamber a is reduced, making it easier for air chamber a to be in a negative pressure state.

[0065] In actual implementation, the distance between two adjacent limit blocks 210 can be made as close as possible, provided that the suction end of the suction device 300 does not obstruct the suction of the air chamber a.

[0066] like Figure 2 and Figure 6 As shown, for example, there are multiple air chambers a. The mounting base 100 is provided with an air extraction channel 150. The air extraction channel 150 has a first air port and multiple second air ports 151. The first air port is connected to the air extraction end of the air extraction device 300, and the second air ports 151 are connected to the air chambers a respectively.

[0067] In this example, the gas in multiple air chambers a can flow from their corresponding second air ports 151 through the suction channel 150, and then from the first air port into the suction end of the suction device 300. That is, in this example, the gas pressure in multiple air chambers a can be adjusted by a single suction device 300.

[0068] In actual implementation, the air extraction device 300 can be an air pump.

[0069] In actual operation, the extraction end of the extraction device 300 is connected to the air chamber a through a multi-way valve.

[0070] This allows the multi-way valve to switch the air extraction end of the air extraction device 300 to connect with the first air port, or to switch the first air port to connect with the ambient gas, thereby adjusting the air pressure in the air chamber a to negative pressure or restoring it to normal pressure.

[0071] In some embodiments, a compressed sealing gasket is provided between the support block 110 and the screen body 200.

[0072] This design prevents ambient gas from entering the air cavity a from the area between the support block 110 and the screen body 200 when the air pressure in the air cavity a is negative, thus avoiding the failure of the negative pressure state.

[0073] In some embodiments, a sealing strip is airtightly connected between two adjacent screen bodies 200, and the sealing strip is located in the air cavity a.

[0074] This design, when the air pressure in air chamber a is in a negative pressure state, can prevent ambient gas from entering air chamber a from the area between two adjacent screen bodies 200, thus preventing the negative pressure state from failing.

[0075] In some embodiments, the mounting base 100 has a slot, and multiple screen bodies 200 abut against each other to form a splicing screen, with the splicing screen pressed against the slot.

[0076] This design serves two purposes: firstly, when the air pressure inside air chamber a is negative, it prevents ambient gas from entering air chamber a from the area between the slot wall of the mounting base 100 and the splicing screen, thus preventing the negative pressure state from failing; secondly, it also makes the overall splicing screen system more aesthetically pleasing.

[0077] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
