Description

Technical Field

[0001] This utility model relates to the field of LED panel technology, and in particular to a fast-installation LED screen. Background Technology

[0002] LED large screens are large display screens used to display various information such as text, graphics, images, animations, market information, videos, and recorded signals.

[0003] LED large screens are typically made up of multiple small modules that are connected together to achieve a larger display effect. The area of ​​the LED large screen can be arbitrarily combined according to different venues and needs. However, the previous module splicing technology usually used bolts or magnets for splicing and assembly. Among them, the operation of bolt assembly is more complicated and the work efficiency is lower. Although the assembly using magnets improves the work efficiency, the lack of fixing devices poses a risk of falling off, which poses certain safety hazards during use. Utility Model Content

[0004] The purpose of this invention is to provide a fast-installation LED screen that solves the problems of complex operation and low work efficiency when assembling with bolts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-installation LED screen, comprising: multiple crossbeams and multiple modules, multiple sleeves fixedly installed inside the multiple crossbeams, rectangular holes being opened near one end of each of the multiple sleeves, L-shaped plates being rotatably installed on both sides of the multiple rectangular holes, and springs being fixedly connected to the lower side of the outer surface of each of the multiple L-shaped plates, with the other end of each of the multiple springs being connected to one side of the sleeve.

[0006] In a preferred embodiment, slots are provided on one side of the outer surface of the plurality of modules, and the plurality of modules are mounted on the outer surface of the crossbeam through the slots.

[0007] The technical effect of adopting the above-mentioned further solution is that the module can be installed on the outer surface of the sleeve through the slots opened on the module. When the L-shaped plate passes the edge of the slot, it will be squeezed, thereby compressing the second spring. When the L-shaped plate retracts, the sleeve enters the inside of the slot. When 106 is fully inserted, the L-shaped plate is no longer squeezed, and the second spring rebounds to restore the position of the L-shaped plate, so that the module can be fixed on the sleeve and will not fall off.

[0008] In a preferred embodiment, vertical rods are fixedly installed on both sides of the outer surface of the plurality of beams.

[0009] The technical advantage of adopting the above-mentioned further solution is that the vertical rods are installed vertically on both sides of the horizontal beam. Therefore, after the module is installed, the direction of the module can be restricted to ensure that there is no deviation in the precise installation direction.

[0010] In a preferred embodiment, a sliding rod is slidably fitted inside each of the plurality of sleeves.

[0011] The technical effect of adopting the above-mentioned further solution is that the rotation of the L-shaped plate can be controlled by controlling the movement of the slide rod in conjunction with the annular groove at the lower end of the slide rod.

[0012] In a preferred embodiment, pressure plates are fixedly installed on the upper ends of the outer surfaces of the plurality of sliding rods, and springs are fixedly connected to the lower sides of the plurality of pressure plates. The other ends of the plurality of springs are fixedly connected to the upper side of the outer surface of the sleeve.

[0013] The technical effect of adopting the above-mentioned further solution is that when the pressure plate is pressed down, the first spring is compressed. Therefore, when the pressure plate is released, the first spring will provide an upward elastic force to the pressure plate, thus enabling the pressure plate to quickly return to its original position.

[0014] In a preferred embodiment, annular grooves are formed on the outer surfaces of the plurality of sleeves near the lower side, and the other end of the L-shaped plate is embedded in the interior of the annular grooves.

[0015] The technical effect of adopting the above-mentioned further solution is that when it is necessary to remove the module, simply press the pressure plate to make the annular groove at the lower end of the slide rod push one end of the L-shaped plate to rotate, thereby causing the other end of the L-shaped plate to rotate around the pivot and compress the second spring, at which point the module can be removed.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] In use, the module can be installed on the outer surface of the sleeve through the slots on the module. When the L-shaped plate passes the edge of the slot, it will be squeezed, which will compress the second spring. The L-shaped plate will then retract, allowing the sleeve to enter the slot. When the second spring is fully inserted, the L-shaped plate will no longer be squeezed, and the second spring will rebound to restore the L-shaped plate to its original position. This allows the module to be fixed on the sleeve and will not fall off. The installation is quick and does not require bolts.

[0018] 2. In this utility model, when it is necessary to remove the module, pressing the pressure plate causes the annular groove at the lower end of the slide rod to push one end of the L-shaped plate to rotate, thereby causing the other end of the L-shaped plate to rotate around the pivot and compress the second spring. At this time, the module can be easily removed, which facilitates subsequent maintenance. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a quick-installation LED screen, comprising: multiple crossbeams 101 and multiple modules 103. Multiple sleeves 201 are fixedly installed inside the multiple crossbeams 101. Rectangular holes 204 are opened near one end of the multiple sleeves 201. L-shaped plates 205 are rotatably installed on both sides of the multiple rectangular holes 204. Springs 206 are fixedly connected to the lower side of the outer surface of the multiple L-shaped plates 205. The other end of the multiple springs 206 is connected to one side of the sleeves 201.

[0027] like Figures 1-4As shown, slots 104 are provided on one side of the outer surface of multiple modules 103. Multiple modules 103 are installed on the outer surface of the crossbeam 101 through slots 104. Through the slots 104 on the modules 103, the modules 103 can be installed on the outer surface of the sleeve 201. When the L-shaped plate 205 passes the edge of the slot 104, it will be squeezed, thereby compressing the second spring 206. The L-shaped plate 205 retracts, so that the sleeve 201 enters the inside of the slot 104. When 106 is fully inserted, the L-shaped plate 205 is no longer squeezed, and the second spring 206 rebounds to restore the position of the L-shaped plate 205, so that the module 103 can be fixed on the sleeve 201 and will not fall off.

[0028] like Figures 1-4 As shown, vertical rods 102 are fixedly installed on both sides of the outer surface of multiple crossbeams 101. The vertical rods 102 are installed vertically on both sides of the crossbeams 101. Therefore, after the module 103 is installed, the direction of the module 103 can be restricted to ensure that there is no deviation in the precise installation direction.

[0029] like Figures 1-4 As shown, each of the multiple sleeves 201 has a sliding rod 202 slidably mounted inside. By controlling the movement of the sliding rod 202, the rotation of the L-shaped plate 205 can be controlled in conjunction with the annular groove 207 at the lower end of the sliding rod 202.

[0030] like Figures 1-4 As shown, pressure plates 203 are fixedly installed on the upper ends of the outer surfaces of multiple sliding rods 202. Springs 208 are fixedly connected to the lower sides of multiple pressure plates 203. The other ends of multiple springs 208 are fixedly connected to the upper side of the outer surface of the sleeve 201. When the pressure plate 203 is pressed down, the springs 208 are compressed. Therefore, when the pressure plate 203 is released, the springs 208 provide an upward elastic force to the pressure plate 203, thus enabling the pressure plate 203 to quickly return to its original position.

[0031] like Figures 1-4 As shown, annular grooves 207 are provided on the outer surface of multiple sleeves 201 near the lower side. The other end of the L-shaped plate 205 is embedded in the annular groove 207. When it is necessary to remove the module 103, simply press the pressure plate 203 to push one end of the L-shaped plate 205 to rotate through the annular groove 207 at the lower end of the slide rod 202. This will cause the other end of the L-shaped plate 205 to rotate around the pivot, thereby compressing the second spring 206. At this time, the module 103 can be removed.

[0032] Working principle: In use, firstly, the module 103 is inserted into the sleeve 201 on the outer surface of the crossbeam 101 through the slot 104 on the rear side. When the L-shaped plate 205 passes the edge of the slot 104, it will be squeezed, thus compressing the second spring 206. The L-shaped plate 205 retracts, allowing the sleeve 201 to enter the slot 104. When the second spring 206 is fully inserted, the L-shaped plate 205 is no longer squeezed, and the second spring 206 rebounds, restoring the L-shaped plate 205 to its original position. This allows the module 103 to be fixed on the sleeve 201 and prevents it from falling off. When it is necessary to remove the module 103, press the pressure plate 203 to push one end of the L-shaped plate 205 to rotate through the annular groove 207 at the lower end of the slide bar 202. This causes the other end of the L-shaped plate 205 to rotate around the pivot, thus compressing the second spring 206. At this point, the module 103 can be easily removed. When the first module 103 is installed, the vertical rod 102 restricts the module 103 to ensure that the module 103 is installed accurately without deviation, thus ensuring that there will be no errors when installing subsequent modules 103.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
