Threaded sleeves are provided at both ends of the threaded rod, and guide blocks are provided on both sides of the threaded sleeves.

[0005] The outer casing assembly includes two door frames, each with two positioning pins on its bottom sides, and a fixing groove on one side of each positioning pin; the positioning pins and the positioning grooves are connected by an insertion structure; the fixing grooves and the threaded sleeves are connected by a snap-fit ​​structure.

[0006] More preferably, the guide groove and the guide block are configured to slide together.

[0007] More preferably, the mounting base and threaded sleeve are symmetrical about the vertical center line of the door panel to the guide block.

[0008] More preferably, the threaded sleeve and the door panel are configured as a sliding connection.

[0009] According to the foregoing description of this solution, the beneficial technical effects of this utility model include: This technical solution, through the cooperation of positioning pins, positioning slots, and fixing slots, enables the door frame structure of the easy-to-assemble lighting system to be flexibly disassembled and assembled during use. This solves the problem of having to replace the entire cabinet door when it is damaged and needs maintenance, thereby significantly reducing the maintenance cost of the display cabinet door frame.

[0010] This technical solution, through the cooperation of threaded rods, threaded sleeves, and guide blocks, enables the door frame structure, which facilitates the assembly of lighting systems, to be quickly disassembled during use, allowing for the rapid disassembly of door frames or door panels that require maintenance. This significantly improves the convenience of disassembling the door frame and reduces the labor intensity of workers when disassembling it. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a door frame structure for easy assembly of lighting systems, including a shell assembly 1 and two door panels 2. Two positioning grooves 3 are respectively opened at both ends of the two door panels 2. From left to right, hollow glass mounting grooves 4, grooves 5 and light strip mounting grooves 6 are opened on one side of the two door panels 2. Mounting grooves 7 are opened on both sides inside the two grooves 5. Guide grooves 8 are opened on both sides inside the two mounting grooves 7. Mounting seats 9 are provided at the bottom inside the two mounting grooves 7. A threaded rod 10 is provided between the two mounting seats 9 through a bearing. Threaded sleeves 11 are provided on the outside of both ends of the threaded rod 10. Guide blocks 12 are provided on both sides of the two threaded sleeves 11.

[0018] like Figure 1 As shown, the outer casing assembly 1 includes two door frames 101, and two positioning pins 102 are respectively provided on both sides of the bottom end of the two door frames 101. A fixing groove 103 is provided on one side of each of the two positioning pins 102.

[0019] like Figure 2 As shown, the positioning pin 102 and the positioning groove 3 are designed as a plug-in structure; this enables flexible installation of the door frame 101 of the display cabinet door, solving the problem of having to replace the entire cabinet door when it is damaged and needs maintenance, thereby significantly reducing the maintenance cost of the display cabinet door frame 101.

[0020] like Figure 4 As shown, the fixing groove 103 and the threaded sleeve 11 are designed with a snap-fit ​​structure to increase the stability of the door frame 101 and the door panel 2 during use and to prevent the door frame 101 from separating from the door panel 2 during use.

[0021] like Figure 3 As shown, the guide groove 8 and the guide block 12 are configured to slide; this increases the stability of the threaded ferrule 11 during movement, thereby preventing the threaded ferrule 11 from rotating with the rotation of the threaded rod 10 during movement.

[0022] like Figure 2As shown, the mounting base 9 and the threaded sleeve 11 are symmetrical about the vertical center line of the door panel 2 with respect to the guide block 12; this enables the quick disassembly of the door frame 101 or the door panel 2 that needs maintenance, greatly improving the convenience of disassembling the door frame 101 and reducing the labor intensity of workers when disassembling the door frame 101.

[0023] like Figure 3 As shown, the threaded sleeve 11 and the door panel 2 are connected by a sliding connection, so that the threaded sleeve 11 moves in a single direction, avoiding the threaded sleeve 11 from shifting or tilting during movement, thereby increasing the stability of the threaded sleeve 11 during movement.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when it is necessary to disassemble the door frame 101 of the display cabinet, the knob is rotated. The knob then rotates the threaded rod 10, which in turn moves the threaded sleeve 11 in cooperation with the guide block 12 and the guide groove 8. Simultaneously, the threaded sleeve 11 disengages from the fixing groove 103, releasing the locking structure between the threaded sleeve 11 and the fixing groove 103. This allows for quick disassembly of the door frame 101 or door panel 2 requiring repair, significantly improving the convenience of disassembling the door frame 101 and reducing the workload. The process of disassembling the door frame 101 reduces the labor intensity of the workers. Then, by pulling the two door frames 101 outward, the door frame 101 causes the positioning pin 102 to disengage from the positioning groove 3, thus enabling flexible installation of the door frame 101 of the display cabinet door. This solves the problem of having to replace the entire cabinet door when it is damaged and needs maintenance, thereby significantly reducing the maintenance cost of the display cabinet door frame 101. The light strip mounting groove 6 can hide the light strip wiring harness, completely eliminating the safety hazards of exposed light strip wiring harness and greatly improving the installation effect.
