Description

Technical Field

[0001] This application relates to the field of displays, and more particularly to a rear maintenance structure for a display. Background Technology

[0002] A display screen is a computer I / O device, or input / output device. It's a tool that transmits electronic files through specific equipment to a screen, which then reflects the data to the human eye. Display screens, especially advertising screens, are often used outdoors, and multiple screens are typically spliced ​​together to provide better display effects. A display screen generally consists of a display cabinet and multiple display modules, each fixedly mounted within the cabinet to form the screen. Currently, when a display module in a display screen is damaged, maintenance is difficult, often requiring the entire display screen to be disassembled to repair that module, resulting in inefficient maintenance. Summary of the Invention

[0003] To improve the maintenance efficiency of display modules, this application provides a rear maintenance structure for display screens.

[0004] The technical solution for a rear maintenance structure for a display screen provided in this application is as follows:

[0005] A rear maintenance structure for a display screen includes a display housing, a control component, and multiple display components. The control component is disposed in the display housing and is used to control each display component. Each display component is disposed in the display housing.

[0006] The display component includes a display module and multiple fixing blocks. Each fixing block is disposed on the display module. Each fixing block includes a rotating part and a fixing part, which are fixedly connected. The display module has multiple rotating holes, and each rotating part passes through and is rotatably connected to each rotating hole. The display housing has multiple through fixing slots. When the display module is installed on the display housing, each rotating part passes through each fixing slot, and each fixing part drives each rotating part to rotate until it is firmly abutted and fixed to the display housing.

[0007] By adopting the above technical solution, when a display module of the screen is damaged and requires maintenance, each fixing part is turned, causing each fixing part to drive each rotating part to rotate until each fixing part is disengaged from the display cabinet. Then, the display module moves away from the display cabinet, causing each rotating part to disengage from its fixing slot, thus freeing the display module from the fixing between it and the display cabinet. This enables post-maintenance of the display screen, making maintenance simpler, more convenient, and more efficient when a display module is damaged. This improves upon the current display screen, where maintenance is difficult when a display module is damaged, requiring the entire display screen to be disassembled to perform maintenance on a single display module, resulting in poor maintenance efficiency.

[0008] Optionally, the rotating hole body has at least one limiting groove, and the rotating part is fixedly provided with at least one limiting block. The limiting block passes through and slides into the limiting groove, so that when the limiting block abuts and engages with one end of the limiting groove body, the fixed part is tightly fixed to the display cabinet, and when the limiting block abuts and engages with the other end of the limiting groove body, the fixed part disengages from the display cabinet and is tightly fixed.

[0009] Optionally, the rotating part is fixedly provided with at least two limiting protrusions, and the rotating hole body is fixedly provided with corresponding limiting protrusions. Each limiting protrusion of the rotating part abuts and cooperates with each limiting protrusion of the rotating hole. At least one set of corresponding limiting protrusions can restrict the rotating part from rotating in one direction, and at least another set of corresponding limiting protrusions can restrict the rotating part from rotating in another direction, so as to stabilize the position of the fixed part.

[0010] Optionally, the display module is fixedly provided with multiple main positioning posts, and the display cabinet is provided with multiple through-hole main positioning holes. When the display module is installed in the display cabinet, each of the main positioning posts passes through each of the main positioning holes.

[0011] Optionally, the display module is slidably fitted with a plurality of auxiliary positioning posts, and a positioning spring is respectively provided between each auxiliary positioning post and the display module. One end of each positioning spring abuts against each of the auxiliary positioning posts, and the other end of each positioning spring abuts against the display module.

[0012] The display cabinet has multiple through auxiliary positioning holes. When the display module is installed in the display cabinet, each of the auxiliary positioning pins passes through each of the auxiliary positioning holes.

[0013] Optionally, the display component further includes a display handle, which is fixedly connected to the display module.

[0014] Optionally, the display cabinet includes a frame, at least one vertical rod, and at least two horizontal rods. Both ends of each vertical rod are fixedly connected to the frame. One end of each horizontal rod is fixedly connected to one of the vertical rods, and the other end of each horizontal rod is fixedly connected to the frame. The length direction of each horizontal rod is perpendicular to the length direction of each vertical rod.

[0015] Optionally, multiple splicing components are also included. Each splicing component is disposed on the display cabinet. Each splicing component includes a splicing rod and a splicing spring. The splicing rod is disposed on one side of the display cabinet and can slide and rotate relative to the display cabinet. One end of the splicing spring abuts against the splicing rod, and the other end of the splicing spring abuts against the display cabinet. A splicing hole for connecting to the splicing rod is opened on the other side of the display cabinet. When two display cabinets are spliced, the splicing rod of one display cabinet passes through and engages with the splicing hole of the other display cabinet.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] When a display module is damaged and requires maintenance, the fixing parts are turned to rotate the rotating parts until they are all disengaged from the display cabinet. The display module then moves away from the cabinet, disengaging the rotating parts from their fixing slots and freeing the module from its fixation. This allows for easier and more efficient maintenance of the display module, addressing the previous difficulty in repairing a damaged module, which required disassembling the entire display and resulting in inefficient maintenance.

[0031] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0032] This application discloses a rear maintenance structure for a display screen. (Refer to...) Figure 1 A rear maintenance structure for a display screen includes a display cabinet 1, a control component 2, multiple display components 3, and multiple splicing components 4. The control component 2 is disposed in the display cabinet 1 and is used to control each display component 3. Each display component 3 is disposed in the display cabinet 1. Each splicing component 4 is disposed in the display cabinet 1 and is used for splicing and fixing between each display cabinet 1.

[0033] Reference Figure 2The display cabinet 1 includes a frame portion 11, two vertical rod portions 12 and four horizontal rod portions 13. Both ends of the two vertical rod portions 12 are fixedly connected to the frame portion 11. One end of each of the two horizontal rod portions 13 is fixedly connected to one vertical rod portion 12, and one end of each of the two horizontal rod portions 13 is fixedly connected to the other vertical rod portion 12. The other end of each horizontal rod portion 13 is fixedly connected to the frame portion 11. The length direction of each horizontal rod portion 13 is perpendicular to the length direction of each vertical rod portion 12.

[0034] Reference Figure 3 and Figure 4 The control component 2 includes a control box 21, a control cover 22, and control components 23. The control box 21 is fixedly installed on the display box 1 and located between the two vertical rods 12. The control cover 22 is rotatably connected to the control box 21 and is used to control the opening or closing of the control box 21. The control components 23 are installed inside the control box 21.

[0035] Reference Figure 5 and Figure 6 The display component 3 includes a display module 31, multiple fixing blocks 32, and a display handle 33. The display module 31 is installed on the display housing 1 and electrically connected to the control component 23. The display module 31 is rectangular. Each fixing block 32 is located on the side of the display module 31 near the display housing 1, and the fixing blocks 32 are evenly distributed on both sides of the width direction of the display module 31. The display handle 33 is fixedly connected to the side of the display module 31 near the display housing 1, thereby facilitating the disassembly and installation of the display module 31.

[0036] Reference Figures 7 to 10 The fixing block 32 includes a rotating part 321 and a fixing part 322, which are fixedly connected. The display module 31 has multiple rotating holes 311 on the side near the display cabinet 1. Each rotating part 321 passes through and is rotatably connected to each rotating hole 311. The display cabinet 1 has multiple through fixing slots 100. When the display module 31 is installed on the display cabinet 1, each rotating part 321 passes through each fixing slot 100, and each fixing part 322 drives each rotating part 321 to rotate until it is tightly fixed against the display cabinet 1.

[0037] Reference Figures 7 to 10 The rotating hole 311 has two limiting grooves 3111. The rotating part 321 is fixedly provided with two limiting blocks 3211. The two limiting blocks 3211 pass through and slide in the two limiting grooves 3111 respectively, so that when the limiting block 3211 abuts with one end of the limiting groove 3111, the fixing part 322 abuts and fixes with the display box 1. At this time, the fixing part 322 is in a locked state. When the limiting block 3211 abuts with the other end of the limiting groove 3111, the fixing part 322 disengages from the display box 1 and is abutted and fixed. At this time, the fixing part 322 is in an unlocked state.

[0038] Reference Figures 7 to 10 The rotating part 321 is fixedly provided with four limiting protrusions 3212, and the rotating hole 311 is fixedly provided with corresponding limiting protrusions 3212. Each limiting protrusion 3212 of the rotating part 321 abuts and cooperates with each limiting protrusion 3212 of the rotating hole 311. Two sets of corresponding limiting protrusions 3212 can restrict the rotating part 321 from rotating in one direction, and the other two sets of corresponding limiting protrusions 3212 can restrict the rotating part 321 from rotating in another direction. Thus, when the fixed part 322 is in the locked or unlocked state, the two sets of corresponding limiting protrusions 3212 abut and cooperate with each other, making it difficult for the rotating part 321 to rotate. A large force needs to be applied to the fixed part 322 to drive the rotating part 321 to rotate, thus making the fixed part 322 more stable when it is in the locked or unlocked state.

[0039] Reference Figures 7 to 10 The display module 31 is fixedly provided with multiple main positioning posts 312, and the display housing 1 has multiple through-hole main positioning holes. When the display module 31 is installed in the display housing 1, each main positioning post 312 passes through its respective main positioning hole. The display module 31 is slidably fitted with multiple auxiliary positioning posts 313. Each auxiliary positioning post 313 and the display module 31 is provided with a positioning spring (not shown in the figure). One end of each positioning spring abuts against each auxiliary positioning post 313, and the other end of each positioning spring abuts against the display module 31. The display housing 1 has multiple through-hole auxiliary positioning holes. When the display module 31 is installed in the display housing 1, each auxiliary positioning post 313 passes through each auxiliary positioning hole, so that when the display module 31 is installed in the display housing 1, each main positioning post 312 passes through each main positioning hole, thereby completing the initial positioning of the display module 31. Then, the position of the display module 31 is finely adjusted, so that each positioning spring pushes each auxiliary positioning post 313 to pass through each auxiliary positioning hole, thereby achieving precise positioning of the display module 31.

[0040] Reference Figure 11 and Figure 12 The splicing assembly 4 includes a splicing rod 41 and a splicing spring 42. The splicing rod 41 is located on one side of the display cabinet 1 and can slide and rotate relative to the display cabinet 1. One end of the splicing spring 42 abuts against the splicing rod 41, and the other end of the splicing spring 42 abuts against the display cabinet 1. The other side of the display cabinet 1 is provided with a splicing hole 200 for connecting with the splicing rod 41. When the two display cabinets 1 are spliced, the splicing rod 41 of one display cabinet 1 passes through and engages with the splicing hole 200 of the other display cabinet 1, thereby realizing the splicing and fixing between the two display cabinets 1.

[0041] The implementation principle of the rear maintenance structure for a display screen according to this application embodiment is as follows: When a display module 31 of the display screen is damaged and requires rear maintenance, each fixing part 322 is turned, thereby causing each fixing part 322 to drive each rotating part 321 to rotate until each fixing part 322 is disengaged from the display cabinet 1. Then, the display module 31 is moved away from the display cabinet 1, thereby causing each rotating part 321 to disengage from each fixing groove 100, thereby causing the display module 31 to be disengaged from the display cabinet 1, thus realizing the rear maintenance of the display screen. This makes maintenance of the display module 31 simpler, more convenient and more efficient when it is damaged, improving the existing display screen. When a display module 31 is damaged, maintenance is difficult and requires disassembling the entire display screen to complete the maintenance of the display module 31, resulting in poor maintenance efficiency of the display module 31.

[0042] 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.
