Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a locking piece structure for positioning a display box. Background Art

[0002] At present, LED display screens are generally composed of multiple independent display unit display cabinets. When different numbers of display unit display cabinets are assembled into a whole LED display screen of different areas, corresponding locking hardware is required to lock the adjacent display unit display cabinets to ensure the normal operation of the display screen.

[0003] At present, the common practice in the industry is to connect multiple display unit display boxes through steel sheet bolt locking. The steel sheet bolt locking method is simple and easy, but it cannot achieve three-dimensional positioning of the display box. The assembly process requires adjustment of the gap and flatness between adjacent display boxes, resulting in low assembly efficiency and limited assembly accuracy. Utility Model Content

[0004] The main purpose of the utility model is to provide a locking piece structure for positioning a display cabinet, which can improve the three-dimensional positioning accuracy between adjacent display unit display cabinets and realize the splicing of display cabinets efficiently and stably.

[0005] To achieve the above-mentioned purpose, the utility model proposes a locking plate structure for positioning a display box, which is used to connect adjacent display boxes, including an angle positioning locking plate, and the end surface of the angle positioning locking plate facing the display box is provided with a locking hole and a positioning column, a locking hole and a positioning column constitute a group of positioning structures, a group of positioning structures is used to be fixedly connected to a display box, and the display boxes to be connected are respectively provided with box mounting holes and positioning holes at corresponding positions of one group of locking holes and positioning columns. When the adjacent display boxes are in a spliced ​​state formed by the angle positioning locking plate, the locking hole and the box mounting hole are coaxially arranged and used to be connected with bolts, and the positioning column is passed through the positioning hole.

[0006] In one embodiment of the present application, the orthographic projection of the corner positioning locking piece is a rectangle, and a group of locking holes and positioning columns are provided at the four corners of the corner positioning locking piece.

[0007] In one embodiment of the present application, the locking holes in two adjacent groups of positioning structures are symmetrically arranged along the central axis, and the positioning columns in two adjacent groups of positioning structures are symmetrically arranged along the central axis.

[0008] In one embodiment of the present application, a stress-reducing groove is formed on the end surface of the angular positioning locking piece facing away from the positioning column. There are multiple stress-reducing grooves, and reinforcing ribs are provided between the multiple stress-reducing grooves.

[0009] In one embodiment of the present application, the end of the positioning post facing away from the angular positioning locking piece is hemispherical, conical or truncated cone-shaped, and the radius of the head of the positioning post gradually decreases in a direction away from the positioning post.

[0010] In one embodiment of the present application, a plurality of connection holes for fixing and installing external connection profiles are opened on the central axis of the corner positioning locking plate.

[0011] The utility model has the following advantages:

[0012] 1. After the bolts pass through the corner positioning locking plate, they are locked to the corners of the display box. The end of the positioning column is hemispherical, conical, or truncated cone-shaped. When the corner positioning locking plate is locked with the bolts, the positioning column is first inserted into the positioning hole of the display box. When the bolts are tightened, the positioning column determines the gap between two adjacent display boxes.

[0013] 2. When display cabinets are assembled into large-area display screens, they are assembled in a vertical and horizontal array. Corner positioning and locking plates are also locked in an array at each of the four adjacent corners. Since the positioning posts on the corner positioning and locking plates are integrally formed with the corner positioning and locking plates, the gaps between adjacent display cabinets on the vertical and horizontal locking corner positioning and locking plates are strictly consistent. That is, when the display cabinets are assembled, the vertical and horizontal gaps between the display cabinets are fixed and do not need to be and cannot be adjusted.

[0014] 3. All factory-produced corner locking plates have the same thickness, the same flatness on the side used for fixing to the actual display cabinet, and the same height of the positioning posts. The depth of the positioning holes in all display cabinets should be the same as the height of the positioning posts. Once the display cabinets are bolted in place, all display cabinets are aligned on the same plane with the corner locking plates, achieving three-dimensional positioning and locking of the display cabinets. This eliminates the need to constantly adjust the flatness of different display cabinets during installation.

[0015] 4. The splicing between different display cabinets can achieve accurate, fast and firm installation and splicing. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0025] Reference Figures 1 to 4 In one embodiment of the present invention, a locking plate structure for positioning a display box is proposed, which is used to connect adjacent display boxes. The end surface of the corner positioning locking plate 1 facing the display box is provided with a locking hole 12 and a positioning column 13. A locking hole 12 and a positioning column 13 constitute a group of positioning structures. A group of positioning structures is used to be fixedly connected to a display box. The display boxes to be connected are respectively provided with box mounting holes and positioning holes corresponding to one group of locking holes 12 and positioning columns 13. When the adjacent display boxes are in a spliced ​​state formed by the corner positioning locking plate 1, the locking hole 12 and the box mounting hole are coaxially arranged and used to be connected with bolts, and the positioning column 13 is passed through the positioning hole.

[0026] When multiple display boxes are assembled together, in order to lock the multiple display boxes and to improve the locking efficiency, it is preferred to use the corner positioning locking piece 1 to lock the corner positions of the display boxes, and the side of the corner positioning locking piece 1 facing the display box should be provided with multiple groups of positioning structures, one group of positioning structures is used to be fixedly connected to one display box.

[0027] The positioning posts 13 mate with the positioning holes of the display cabinet, allowing the corner positioning locking plate 1 to ensure that the locking holes 12 are strictly aligned with the cabinet mounting holes. The multiple locking structures 11 on the corner positioning locking plate 1 can utilize the positioning posts 13 to conveniently connect multiple display cabinets, achieving the goal of quickly, accurately, and securely installing the spliced ​​display cabinets. This also effectively improves the three-dimensional positioning accuracy between adjacent display cabinets.

[0028] See also Figures 3 and 4 In one embodiment of the present application, the orthographic projection of the corner positioning locking piece 1 is a rectangle, and a locking hole 12 and a positioning column 13 are provided at each of the four corners of the corner positioning locking piece 1 .

[0029] Since most display boxes are rectangular, it is preferred that the orthographic projection of the corner positioning locking piece 1 is a rectangle. Four display boxes can be spliced ​​together at the same time using one corner positioning locking piece 1. At the same time, the force between the corner positioning locking piece 1 and multiple display boxes is more uniform, avoiding damage to the corner positioning locking piece 1 during use, and increasing the strength of the corner positioning locking piece 1. The positioning column 13 is arranged at intervals from the locking hole 12 to assist in positioning multiple groups of display boxes. At the same time, it makes it easy to align the display boxes with the locking holes 12 after connecting the display boxes, making it convenient to fix and effectively strengthening the connection between the two. The positioning column 13 is used to assist positioning during the connection process, and after splicing and fixing, the positioning column 13 is passed through the display box, making the entire structure more complex and playing a reinforcing role.

[0030] See also Figure 4 In one embodiment of the present application, the relative positions of the locking holes 12 and positioning posts 13 in two adjacent groups are symmetrical along the central axis. This allows the corner positioning and locking pieces 1 to easily align and lock the four display cabinets after they are assembled. This ensures that the gaps between adjacent display cabinets on the corner positioning and locking pieces 1, which are locked vertically and horizontally, are strictly consistent. That is, when the display cabinets are assembled, the vertical and horizontal gaps between the display cabinets are set to a constant value and do not require or can be adjusted, thereby achieving fast and accurate display cabinet splicing.

[0031] See also Figure 3 In one embodiment of the present application, a stress-reducing groove 14 is formed on the end surface of the corner positioning and locking plate 1 facing away from the positioning post 13. Multiple stress-reducing grooves 14 are provided, and reinforcing ribs are positioned between the multiple stress-reducing grooves 14. The primary function of the stress-reducing grooves 14 is to reduce stress concentration in the corner positioning and locking plate 1, thereby reducing the risk of fracture caused by stress concentration, thereby increasing its service life and fatigue strength. Furthermore, the weight of the corner positioning and locking plate 1 is effectively reduced, and the reinforcing ribs further ensure the strength of the entire corner positioning and locking plate 1.

[0032] See also Figures 1 to 3In one embodiment of the present application, the end of the positioning post 13 facing away from the angular positioning locking plate 1 is hemispherical, conical, or truncated cone-shaped, and the radius of the head of the positioning post 13 gradually decreases as it moves away from the positioning post 13. This structure allows the positioning post 13 to be inserted into the positioning hole more accurately and quickly. The smooth cylindrical body of the positioning post 13 ensures smooth insertion, making the splicing process of multiple display cabinets more efficient and accurate.

[0033] See also Figures 1 to 4 In one embodiment of the present application, a plurality of connection holes 15 for fixing and installing the connection profile 2 are opened on the central axis of the corner positioning locking plate 1.

[0034] Before installing the display box on a wall or mounting bracket, it is necessary to fix the corner positioning locking plate 1 to the connecting profile 2, and then install the display screen to the cavity or mounting bracket through the connecting profile 2. The setting of the connecting hole 15 realizes the quick connection between the connecting profile 2 and the corner positioning locking plate 1.

[0035] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
