Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and more specifically to a fast-installation wiring structure for LED displays. Background Technology

[0002] LED displays, as flat panel display devices with light-emitting diodes (LEDs) as their core display element, have diversified information display capabilities and can effectively present various content such as text, graphics, images, animations, and videos. They are widely used in advertising media, public displays, stage performances, and many other fields.

[0003] A search revealed a utility model patent with publication number CN213402319U, which discloses a cable structure for a full-color LED display screen. The structure includes a first locking cover and a second locking cover, which are attached to each other on opposite sides and each side has a cable groove. A connecting plate is fixedly installed at the middle position of the upper two sides of the second locking cover, and a locking spring is fixedly installed inside the upper side of the connecting plate.

[0004] However, while the cable tray design in this patent enables neat cable arrangement and solves the problem of messy cables in traditional cabling to some extent, it has significant technical limitations in actual installation. Workers must first press each cable completely into the cable tray one by one, and only after all cables are accurately positioned can the two locking covers be engaged to secure the wires. This results in cumbersome and time-consuming procedures, directly leading to low cabling efficiency. Furthermore, it not only extends the working time of installers but also significantly increases their labor intensity. Especially when the LED display requires a large number of cables, workers need to invest considerable time and effort in pressing the cables in and engaging the covers, ultimately causing a significant decrease in overall installation efficiency and increasing labor costs, which is detrimental to large-scale installation operations. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fast-installation wiring structure for LED displays to solve the problems existing in the background art.

[0006] The utility model provides the following technical solution: a fast-installable wiring structure for an LED display screen, including a mounting base. The mounting base has equidistant wire-pressing grooves on its surface. Silicone protrusions are equidistantly fixed to both sides of the inner wall of each wire-pressing groove. A cover plate is hinged to the side of the mounting base. A groove is formed on the surface of the cover plate. Transparent acrylic sheets are fixedly embedded on both sides of the inner wall of the cover plate. A sliding groove is formed on the surface of the cover plate between two transparent acrylic sheets. Limiting grooves are formed on both sides of the sliding groove. An extrusion assembly is installed inside the sliding groove.

[0007] Furthermore, a connecting column is fixedly connected to the side of the fixed base, and a clamping plate is fixedly connected to the end face of the connecting column. A fixing bolt is threaded onto the surface of the clamping plate, and the clamping plate is U-shaped.

[0008] Furthermore, the extrusion assembly includes a sliding seat slidably connected inside the slide groove. Sliding blocks are fixedly connected to both sides of the sliding seat. The outer surface of the sliding blocks is slidably connected to the inside of the limiting groove. An adjusting bolt is rotatably connected to the inside of the sliding seat via a bearing. A threaded cylinder is threadedly connected to the outer surface of the adjusting bolt. A sliding column is fixedly connected to the end face of the threaded cylinder. Rotating grooves are equidistantly opened on the surface of the sliding column. A rotating wheel is rotatably connected to the inside of the rotating groove via a rotating shaft. A limiting rod is fixedly connected to the surface of the sliding column. The outer surface of the limiting rod is slidably connected to the inside of the sliding seat.

[0009] Furthermore, the end of the adjusting bolt away from the threaded cylinder extends to the outside of the sliding seat. When the cover plate and the fixed seat are closed, the pressure groove is covered by the inside of the groove, and at the same time, the outer surface of the rotating wheel is inserted into the inside of the pressure groove.

[0010] Furthermore, the outer surface of the threaded cylinder is inserted into the interior of the sliding seat, and the rotating wheel is a silicone wheel.

[0011] Furthermore, magnets are embedded and fixed on the sides of both the cover plate and the fixing base, with opposite magnetic properties on the opposite sides of the two magnets.

[0012] The technical effects and advantages of this utility model are as follows: 1. Compared to the cumbersome process of traditional wire-fixing structures that require pressing each cable completely into the wire groove before closing the cover, this utility model only requires placing one end of the cable into the wire-pressing groove. After closing the cover, the cable can be quickly and completely pressed in by sliding the pressing component. The rolling design of the rotating wheel in the pressing component reduces the friction between the cable and the structure. With the help of the adjusting bolt, the pressing force can be flexibly controlled to adapt to different cable diameters without repeated adjustments. Especially in scenarios with a large number of cables in LED displays, it can significantly shorten the single wiring time, reduce the labor intensity of installers, provide convenience for large-scale installation operations, and indirectly reduce labor costs.

[0013] 2. The silicone protrusions on the inner wall of the wire clamping groove of this utility model can increase the friction with the outer sheath of the cable, preventing the cable from shifting due to vibration and other factors during use. At the same time, the silicone material has a certain degree of elasticity, which can adapt to cables of different thicknesses and provide stable clamping force. The cover plate and the fixing seat are closed by magnets with opposite magnetic properties, ensuring that the structure is stable after closure and preventing the cover plate from loosening and causing the cable to fall out. In addition, the transparent acrylic plates on both sides of the cover plate can observe the cable arrangement sequence in real time, which is convenient for checking whether the cable arrangement is correct after installation, avoiding the impact of cable misalignment on the normal operation of the LED display screen, improving the overall installation quality and the convenience of subsequent maintenance.

[0016] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0017] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0018] A fast-installation wiring structure for an LED display includes a mounting base 1. The surface of the mounting base 1 is provided with equidistant wire pressing grooves 5. Silicone protrusions are fixedly connected to both sides of the inner wall of the wire pressing grooves 5 at equal intervals. A cover plate 6 is hinged to the side of the mounting base 1. The surface of the cover plate 6 is provided with grooves 7. Transparent acrylic plates 8 are fixedly embedded in both sides of the inside of the cover plate 6. A sliding groove 9 is provided on the surface of the cover plate 6 between the two transparent acrylic plates 8. Limiting grooves 10 are provided on both sides of the sliding groove 9. An extrusion assembly 11 is installed inside the sliding groove 9.

[0019] In this embodiment, the mounting base 1 serves as the basic load-bearing component. The wire clamping groove 5 on its surface provides dedicated space for the cables, preventing multiple cables of the LED display from scattering randomly. The silicone protrusions fixed at equal intervals on both sides of the inner wall of the wire clamping groove 5 can significantly increase the friction with the cable sheath, effectively preventing the cables from shifting due to vibration, equipment movement, or other factors during the operation of the LED display, thus ensuring the stability of the cable connection. On the other hand, the silicone material itself has good elasticity, which can adapt to cables of different thicknesses and specifications, clamping the cables while avoiding damage to the cable sheath and extending the service life of the cables.

[0020] The groove 7 provides space for the extrusion assembly 11 to operate, avoiding interference between the extrusion assembly 11 and the surface of the cover plate 6. The transparent acrylic plate 8 allows real-time observation of the cable arrangement inside the wire pressing groove 5, facilitating quick inspection of the correct wiring after installation, reducing LED display failures caused by cable misalignment, and improving installation quality and subsequent maintenance efficiency. The combination of the slide groove 9 and the limiting groove 10 provides precise guidance for the sliding of the extrusion assembly 11, ensuring that the extrusion assembly 11 maintains a stable trajectory during lateral movement, avoiding deviation that could lead to uneven wire pressing, and ensuring the wire pressing effect.

[0021] Specifically, a connecting post 2 is fixedly connected to the side of the fixed base 1, a clamping plate 3 is fixedly connected to the end face of the connecting post 2, and a fixing bolt 4 is threadedly connected to the surface of the clamping plate 3. The clamping plate 3 is "U" shaped.

[0022] In this embodiment, the connecting column 2 fixed to the side of the fixing base 1 can stably connect the fixing base 1 and the clamping plate 3, realizing the indirect connection between the fixing base 1 and the external installation structure. The clamping plate 3 is designed as a "U" shape, which can be flexibly fitted into the corresponding position of the LED display mounting bracket, adapting to different specifications of bracket structures, improving the versatility of the fixing structure. Tightening the fixing bolt 4 can make the end face of the fixing bolt 4 tightly abut against the surface of the bracket, thereby firmly fixing the clamping plate 3 on the bracket, thus realizing the stable installation of the fixing base 1, avoiding the fixing base 1 from loosening or shifting during wiring and use, ensuring the overall stability of the wiring structure, and providing a reliable foundation for subsequent cable fixing.

[0023] Specifically, the extrusion assembly 11 includes a sliding seat 111 slidably connected inside the slide groove 9. Sliding blocks 112 are fixedly connected to both sides of the sliding seat 111. The outer surface of the sliding blocks 112 is slidably connected to the inside of the limiting groove 10. An adjusting bolt 113 is rotatably connected to the inside of the sliding seat 111 via a bearing. A threaded cylinder 114 is threadedly connected to the outer surface of the adjusting bolt 113. A sliding column 116 is fixedly connected to the end face of the threaded cylinder 114. Rotating grooves 117 are equidistantly opened on the surface of the sliding column 116. A rotating wheel 118 is rotatably connected to the inside of the rotating groove 117 via a rotating shaft. A limiting rod 115 is fixedly connected to the surface of the sliding column 116. The outer surface of the limiting rod 115 is slidably connected to the inside of the sliding seat 111.

[0024] In this embodiment, in the extrusion assembly 11, the sliding seat 111 is slidably connected inside the slide groove 9 and serves as the bearing base for the entire extrusion assembly 11. The sliding blocks 112 fixed on both sides of the sliding seat 111 are slidably engaged with the limiting groove 10, which can accurately limit the sliding direction of the sliding seat 111, preventing the sliding seat 111 from shifting up and down or falling off during movement, and ensuring the stable operation of the extrusion assembly 11. The adjusting bolt 113 inside the sliding seat 111 is rotatably connected by a bearing, which can realize the axial movement of the threaded cylinder 114 by rotation, providing an operating component for adjusting the pressing force. The adjusting bolt 113 and the threaded cylinder 114 are threadedly engaged, with high transmission accuracy, which can realize the smooth movement of the threaded cylinder 114 and avoid sudden changes in the pressing force due to excessive adjustment.

[0025] The sliding column 116, fixed to the end face of the threaded cylinder 114, is the core component for mounting the rotating wheel 118. The rotating groove 117 on its surface provides installation space for the rotating wheel 118. The rotating wheel 118 is rotatably connected to the inside of the rotating groove 117 via a rotating shaft, which can achieve rolling during the wire pressing process. This transforms traditional sliding friction into rolling friction, significantly reducing the friction between the cable and the extrusion assembly 11, preventing damage to the cable sheath during the wire pressing process, and reducing the force required by the sliding extrusion assembly 11, making it easier for workers to operate.

[0026] The limiting bar 115, which is fixed on the surface of the sliding column 116, is slidably connected inside the sliding seat 111. It can limit the movement direction of the threaded cylinder 114 and the sliding column 116, prevent the threaded cylinder 114 from rotating synchronously with the rotation of the adjusting bolt 113, ensure that the threaded cylinder 114 moves only along the axial direction, and ensure the stable realization of the adjusting bolt 113's function of adjusting the pressure force.

[0027] Specifically, the end of the adjusting bolt 113 away from the threaded cylinder 114 extends to the outside of the sliding seat 111. When the cover plate 6 and the fixed seat 1 are closed, the pressure groove 5 is covered by the inside of the groove 7, and at the same time, the outer surface of the rotating wheel 118 is inserted into the inside of the pressure groove 5.

[0028] In this embodiment, the end of the adjusting bolt 113 away from the threaded cylinder 114 extends to the outside of the sliding seat 111, allowing the operator to directly rotate the adjusting bolt 113 from the outside after the cover plate 6 is closed, thus adjusting the wire pressing force without opening the cover plate 6, simplifying the operation process and improving work efficiency. When the cover plate 6 and the fixed seat 1 are closed, the wire pressing groove 5 is covered by the inside of the groove 7, forming a relatively closed space between the groove 7 and the wire pressing groove 5, which fully wraps the cable inside the wire pressing groove 5, enhancing the protection of the cable. At the same time, the outer surface of the rotating wheel 118 is inserted into the inside of the wire pressing groove 5, ensuring that the rotating wheel 118 can directly contact the cable inside the wire pressing groove 5, providing the prerequisite for the subsequent complete pressing of the cable into the wire pressing groove 5 by the sliding pressing component 11, and avoiding wire pressing failure due to inadequate contact between the rotating wheel 118 and the cable.

[0029] Specifically, the outer surface of the threaded cylinder 114 is inserted into the interior of the sliding seat 111, and the rotating wheel 118 is a silicone wheel.

[0030] In this embodiment, the outer surface of the threaded cylinder 114 is inserted into the interior of the sliding seat 111, enabling the threaded cylinder 114 to move smoothly within the sliding seat 111, reducing wobbling during movement, and ensuring that the threaded cylinder 114 drives the sliding column 116 and the rotating wheel 118 to accurately apply pressure to the cable, thus improving the stability of the wire pressing. The rotating wheel 118 is made of silicone. Silicone has good elasticity and wear resistance. On the one hand, it can make flexible contact with the cable surface during the wire pressing process, avoiding damage to the cable sheath due to rigid compression. On the other hand, the high friction of the silicone material ensures that the rotating wheel 118 can effectively drive the cable to move during rolling, pressing the cable completely into the wire pressing groove 5. At the same time, the wear resistance of the silicone wheel extends the service life of the rotating wheel 118 and reduces maintenance costs.

[0031] Specifically, magnets are embedded and fixed on the sides of both the cover plate 6 and the fixing base 1, and the opposing surfaces of the two magnets have opposite magnetic properties.

[0032] In this implementation scheme, magnets are embedded and fixed on the sides of both the cover plate 6 and the fixing base 1. The opposing surfaces of the two magnets have opposite magnetic properties. Utilizing the principle of attraction between opposite magnetic poles, when the cover plate 6 is closed, the two magnets generate a stable attractive force, firmly adhering the cover plate 6 to the fixing base 1. This ensures that the cover plate 6 will not easily loosen or fall off after being closed, preventing the cable from coming out of the cable clamping groove 5 due to the cover plate 6 loosening, and ensuring the stability of the cable fixation. At the same time, the magnetic closure method is simple to operate. Workers can quickly complete the closing and opening of the cover plate 6 without the need for additional tools. Compared with the traditional buckle and bolt fixing methods, this greatly simplifies the operation process, shortens the opening and closing time of the cover plate 6 during cable laying, and further improves the overall installation efficiency.

[0033] The working principle and usage process of this utility model are as follows: In use, the clamping plate 3 is fitted onto the bracket at the designated position. Then, the fixing bolt 4 is turned with a wrench to fix the clamping plate 3 onto the bracket. At this time, the fixing seat 1 is also fixed. After connecting the cable to the display screen, all cables are pressed into the wire pressing groove 5 at one end; they do not need to be fully pressed into the wire pressing groove 5. Then, the cover plate 6 is closed. The magnets installed on the opposing surfaces of the cover plate 6 and the fixing seat 1 ensure the sturdiness of the cover plate 6 after it is closed. After closing the cover plate 6, the rotating wheel 118 is located inside the wire pressing groove 5. If a smaller cable diameter is required, the cable needs to be pressed deeper into the wire pressing groove 5. At this time, the adjusting bolt 113 is turned clockwise to adjust the wire pressing groove 5. The engagement with the threaded cylinder 114 causes the threaded cylinder 114 to drive the sliding column 116 to slide closer to the cable. At this time, the pressure of the rotating wheel 118 on the cable increases, and the cable can be pressed into the specified depth. Then, the adjusting bolt 113 is stopped from rotating. Then, by applying a lateral force to the adjusting bolt 113, the sliding seat 111, the threaded cylinder 114 and the sliding column 116 slide inside the groove 7. At the same time, the rotating wheel 118 rolls inside the wire pressing groove 5, pressing the cable completely into the wire pressing groove 5. The silicone protrusions on the inner wall of the wire pressing groove 5 abut against the cable sheath, which can improve the firmness of the cable inside the wire pressing groove 5. After the cable is laid out, the cable laying sequence can be observed through the two transparent acrylic plates 8 to improve the standardization of the cable laying.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
