Description

Technical Field

[0001] This utility model relates to the field of frame connection technology, and in particular to a connection structure for die-cast aluminum box frames and LED screens. Background Technology

[0002] In the fields of LED display and industrial equipment housings, die-cast aluminum housing frames are widely used to construct spliced ​​structures due to their advantages such as high strength, lightweight and good heat dissipation. The stable connection between adjacent die-cast aluminum housing frames is an important link to ensure the overall structural reliability and assembly efficiency, and the design of the connection structure directly affects the ease of assembly, material management costs and material utilization.

[0003] Currently, there are some connection structures used for die-cast aluminum box frames. The layout of the mounting holes of the connecting pieces corresponds to the connection holes on the edge of the box frame in a fixed relationship. When the connection structure is used on the upper or lower edge or left or right edge of the box frame, it is necessary to perform horizontal or vertical cutting processing on the connection structure according to the edge type. The connection structure must be cut to half of its original size before it can be matched with the holes and fixed. The cutting process results in the connection structure needing to be distinguished from various specifications and the materials being complicated. This greatly increases the difficulty of production preparation, warehousing management and material sorting during assembly. A large amount of scrap material is also generated during the cutting process, resulting in waste of metal materials and directly increasing production costs. Additional cutting operations are required before assembly, which reduces assembly efficiency.

[0004] Therefore, there is an urgent need for a connection structure for die-cast aluminum housing frames that can solve the problem of traditional connection structures requiring cutting and adaptation, realize universal connection between adjacent die-cast aluminum housing frames, simplify the assembly process, and reduce material management and material costs.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] This embodiment discloses a connection structure 10 for die-cast aluminum box frames, used to connect at least two adjacent die-cast aluminum box frames 20, such as... Figures 1-7 As shown, in this embodiment, the connection structure 10 for the die-cast aluminum box frame includes a connecting frame 1 and a connector. The connecting frame 1 is square, and mounting holes 11 are respectively provided on the four vertices of the connecting frame 1. The distance between two adjacent mounting holes 11 is equal to the straight-line distance between the corresponding two adjacent connecting holes 201 of the die-cast aluminum box frame 20. The two mounting holes 11 and the two connecting holes 201 are set one-to-one. The connector passes through the mounting holes 11 and the connecting holes 201 in sequence. The symmetry of the square makes the mounting holes 11 at the four vertices consistent in position. The distance between adjacent mounting holes 11 matches the straight-line distance between the box frame connecting holes 201, realizing a universal connection between two adjacent die-cast aluminum box frames 20. It can adapt to the connection of the upper, lower, left and right edges of the box frame without the need to cut the connector horizontally or vertically, reducing the types of materials, simplifying the box frame installation process, reducing the difficulty of material control, avoiding material waste caused by cutting, thereby reducing material costs and improving the overall assembly efficiency and economy.

[0040] Preferably, in this embodiment, the connector is a nut, and the connecting hole 201 is a blind hole with threads on its inner wall. The connector is adapted to the threads, enabling direct threaded connection between the nut and the connecting hole 201. This eliminates the need for additional bolts or other accessories, reducing the types of materials and assembly steps. Furthermore, the blind hole structure prevents the threads from penetrating the box frame, ensuring the structural integrity of the box frame. The threaded connection also improves connection stability and ease of assembly and disassembly. In other embodiments, the connector can also be a rivet or a clip.

[0041] Preferably, such as Figure 2 and Figures 5-7As shown, in this embodiment, a nut head receiving groove 12 is provided above the mounting hole 11. The diameter of the nut head receiving groove 12 is larger than the diameter of the mounting hole 11, the diameter of the mounting hole 11 is smaller than the diameter of the nut head, and the thickness of the nut head receiving groove 12 is larger than the thickness of the nut head. This allows the nut head to be completely embedded in the receiving groove, preventing the nut head from being exposed. It keeps the surface of the connecting structure flat, preventing damage caused by the protruding nut head or interference with the installation of other components. By limiting the nut head through the receiving groove, the offset of the nut during the connection process can be reduced, improving the connection stability. It can also protect the nut head from external environmental corrosion and extend the service life of the connector.

[0042] Preferably, such as Figure 1 As shown, in this embodiment, a first weight-reducing groove 13 is also provided between two adjacent mounting holes 11, which can reduce the material usage and weight of the connecting frame 1 without affecting the fitting accuracy of the connecting frame 1 and the connecting parts and the overall connection stability, thereby reducing material costs and production and processing costs.

[0043] Preferably, such as Figure 1 As shown, in this embodiment, two first weight-reducing grooves 13 are provided, spaced apart, to avoid a decrease in the local structural strength of the connecting frame 1 due to concentrated weight-reducing grooves. The double weight-reducing groove design further optimizes the weight-reduction effect and reduces material costs, while the spaced layout preserves the structural integrity of a portion of the connecting frame 1, ensuring that the load-bearing capacity and connection stability around the mounting hole 11 are not affected. In other embodiments, one, three, or four first weight-reducing grooves 13 may also be provided.

[0044] Specifically, such as Figures 1-7 As shown, in this embodiment, the connecting frame 1 is also provided with a positioning hole 14, which is correspondingly provided with the positioning groove 202 of the die-cast aluminum box frame 20. The connecting structure 10 for the die-cast aluminum box frame also includes a positioning component, which passes through the positioning hole 14 and the positioning groove 202 in sequence to achieve the pre-positioning of two adjacent die-cast aluminum box frames 20. This allows the box frames to be accurately aligned and temporarily fixed before formal fixing, avoiding installation difficulties caused by positional offset when inserting connecting components later, reducing adjustment time to further improve assembly efficiency, and reducing the risk of component damage caused by inaccurate positioning.

[0045] Preferably, such as Figures 1-7As shown, in this embodiment, two positioning holes 14 are provided between two adjacent mounting holes 11 on the connecting frame 1. The positioning holes 14 are spaced apart from the mounting holes 11. The two positioning holes 14 are symmetrically distributed with the line connecting the midpoint of the line connecting the two mounting holes 11 and the center point of the connecting frame 1 as the axis of symmetry. This achieves more balanced and accurate pre-positioning of the two adjacent die-cast aluminum box frames 20, avoiding box frame offset and uneven force distribution problems that may be caused by a single positioning point or asymmetrical positioning. This further improves positioning stability and accuracy, ensures that the position is perfectly matched when the subsequent connectors are installed, reduces the number of installation adjustments, and the symmetrical design is compatible with the square structure of the connecting frame 1 without compromising the overall universality. In other embodiments, three, four, or five positioning holes 14 may also be provided between two adjacent mounting holes 11 on the connecting frame 1.

[0046] Preferably, such as Figures 1-2 As shown, in this embodiment, a second weight-reducing groove 15 is also provided between two adjacent positioning holes 14 on the connecting frame 1, which can reduce the production material cost of the connecting frame 1 and reduce the overall weight of the die-cast aluminum box frame 20 after assembly without affecting the positioning and fixing function of the connecting frame 1.

[0047] Preferably, in this embodiment, the positioning element is a positioning pin, which can accurately pass through the positioning hole 14 of the connecting frame 1 and the positioning groove 202 of the die-cast aluminum box frame 20, further enhancing the pre-positioning effect of the two adjacent box frames. The positioning pin has the characteristics of simple structure and high positioning accuracy, and can be quickly inserted to complete the pre-fixing. At the same time, the positioning pin is low in cost and easy to purchase, and will not increase the difficulty of material control or material cost. In other embodiments, the positioning element can also be a positioning post or a positioning bolt, etc.

[0048] Preferably, in this embodiment, the connecting frame 1 is made of die-cast aluminum. The high flatness of the die-cast aluminum material ensures that the connecting frame 1 fits tightly with the box frame, avoiding connection gaps or uneven stress caused by uneven contact surfaces, ensuring the accuracy of connector installation. The good strength of the die-cast aluminum material provides reliable support for adjacent box frames, resists external impacts during assembly and use, prevents deformation of the connecting structure, and improves the overall structural stability. The lighter weight of the die-cast aluminum material can reduce the overall weight of the box frame after assembly while ensuring strength, facilitating subsequent handling and installation operations, reducing transportation energy consumption, and without adding extra load to the box frame.

[0049] This embodiment also discloses an LED large screen, including LED beads, die-cast aluminum cabinet frames 20, and a connecting structure 10 for the die-cast aluminum cabinet frames. The LED beads are arranged in a matrix at intervals on the die-cast aluminum cabinet frames 20. The die-cast aluminum cabinet frames 20 are arranged in a matrix. Both ends of the connecting structure 10 for the die-cast aluminum cabinet frames are simultaneously connected to at least two adjacent die-cast aluminum cabinet frames 20. The LED large screen can achieve the splicing of display images of different sizes by the matrix-arranged die-cast aluminum cabinet frames 20. At the same time, the connecting structure 10 for the die-cast aluminum cabinet frames ensures that adjacent die-cast aluminum cabinet frames 20 are stably connected. The matrix-arranged LED beads can present a clear display effect. The matrix design makes the screen size flexible and adjustable, which can adapt to different usage scenarios. The connecting structure 10 for the die-cast aluminum cabinet frames improves the stability of the cabinet splicing, avoids loosening during use, and thus ensures the integrity and stability of the overall display image.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
