Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED splicing screen frame technology, specifically to an LED splicing screen frame structure. Background Technology
[0002] An LED display screen is composed of multiple LED unit cabinets spliced together. When there are many LED unit cabinets and the overall LED splicing screen is large, each LED unit cabinet needs to be fixed on the bracket (LED splicing screen frame). However, the number of each splicing screen is different, so the area is not fixed. A universal LED splicing screen frame structure is required.
[0003] The existing patent, CN222580708U, entitled "An LED Splicing Screen Frame Structure," discloses an LED splicing screen frame structure. This utility model relates to the field of LED splicing screen frame technology and includes a frame base. The front end of the frame base has frame crossbars at both the top and bottom, and one of the frame crossbars has frame vertical bars on both sides of its bottom end. This LED splicing screen frame is movably connected to displacement vertical bars via the front end of the displacement crossbars, allowing operators to easily adjust the position of the displacement vertical bars according to the style of LED splicing screens of different lengths at the same height. The front end of the frame crossbars has movably connected to side-flipping blocks at both the top and bottom, allowing the side-flipping blocks to be flipped open from the inside of the frame crossbars via a rotating seat, and then the LED splicing screen can be placed inside the frame base. This facilitates the placement of the LED splicing screen. After the LED splicing screen is placed, the positioning slider at the upper end of the side-flipping block engages with the groove on the inner side of the frame crossbar, thereby clamping and fixing the LED splicing screen.
[0004] The aforementioned device is movably connected to a vertical displacement rod at the front end of a horizontal displacement rod, which allows staff to adjust the position of the vertical displacement rod according to the style of LED splicing screens of different lengths but the same height. However, the size of the frame is fixed, while the size of the splicing screen is determined according to actual usage needs, which cannot accommodate most splicing screens and cannot well meet people's usage needs. In view of the above situation, technical innovation is carried out on the basis of the existing splicing screen frame structure. Utility Model Content
[0005] The purpose of this utility model is to provide an LED splicing screen frame structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an LED splicing screen frame structure, including a long frame and corner blocks. An insert is installed on the left side of the long frame, and the corner blocks are installed on the right side of the long frame. A short frame is installed below the corner blocks. An internal hexagon screw is installed inside the insert, and the internal hexagon screw is threadedly connected to the insert. According to the size of the splicing screen, a certain number of long frames are connected to each other by inserts and fixed with internal hexagon screws. The short frames are connected and installed in the same way. After the long and short sides are inserted into the edge of the splicing screen, the corner blocks are used to connect the long and short sides.
[0007] Furthermore, a connecting block is installed at the rear end of the long frame, and the connecting block is welded to the long frame.
[0008] Furthermore, the connecting block is internally fitted with an external hexagonal screw, and the external hexagonal screw is threadedly connected to the connecting block. Connecting blocks are provided on both the long and short sides.
[0009] Furthermore, a cross bracket is installed on one side of the external hexagonal screw, and the cross bracket and the external hexagonal screw are threaded together. The cross bracket and the connecting block are installed and fixed using the external hexagonal screw, and the cross brackets are also connected and fixed together using external hexagonal screws.
[0010] Furthermore, a wire harness assembly is installed inside the cross-shaped bracket, and the wire harness assembly is embedded in the cross-shaped bracket.
[0011] Furthermore, the cable harness assembly includes a clamp and a ring clamp, and a ring clamp is installed on one side of the clamp. The clamp is inserted into the square hole on the cross bracket, and the cable is fixed to the clamp by the ring clamp, which facilitates cable management.
[0012] Furthermore, a cooling fan is installed at the rear end of the cross bracket, and the cooling fan is embedded in the cross bracket. The heat generated when the splicing screen is working is quickly dissipated through the cooling fan by accelerating air circulation, thus extending its service life.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: According to the size of the splicing screen, a certain number of long frames are connected to each other by interlocking blocks and fixed with hexagonal screws. The short frames are connected and installed in the same way. After the long and short sides are embedded into the edge of the splicing screen, corner blocks are used to connect the long and short sides, thereby fixing the splicing screen inside the frame. The size of the frame can be freely adjusted according to the needs, and the versatility is better. Hexagonal screws are used to install and fix the cross brackets and connecting blocks. Hexagonal screws are also used to connect and fix the cross brackets, thereby strengthening the connection between the long and short frames. The clips are inserted into the square holes on the cross brackets, and the cables are fixed to the clips by the ring clamps, which facilitates cable management. The heat generated by the splicing screen during operation is quickly dissipated by the cooling fan to accelerate air circulation, thus extending the service life.
[0014] 1. This utility model connects a certain number of long frames with each other by interlocking blocks according to the size of the splicing screen and fixes them with hex screws. The short frames are connected and installed in the same way. After the long and short sides are embedded into the edge of the splicing screen, corner blocks are used to connect the long and short sides, thereby installing and fixing the splicing screen inside the frame.

[0015] 2. This utility model uses external hexagonal screws to install and fix the cross bracket and the connecting block. The cross brackets are also connected and fixed with external hexagonal screws, thereby strengthening the connection between the long frame and the short frame. The clip is inserted into the square hole on the cross bracket, and the cable is fixed to the clip by the ring clamp, which facilitates cable management. The heat generated by the splicing screen during operation is quickly dissipated by the cooling fan to accelerate air circulation and extend the service life. Attached Figure Description
