[0027] To address the problem of time-consuming and labor-intensive assembly and maintenance caused by the screw-based fixing of existing LED downlights between the lamp holder and the lampshade, this utility model provides an easily detachable LED downlight. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Please see Figure 1-9 This utility model provides an easy-to-disassemble LED downlight, including a lamp holder 1 and a lamp cover 2. The lamp holder 1 and the lamp cover 2 are provided with fixing locking plates 11 on both sides of the connection end face. The fixing locking plates 11 are L-shaped, and the upper part of the fixing locking plates 11 is provided with two sets of positioning posts 12.

[0029] Rotary locking structures 3 are provided on both sides of the connection end face between the lampshade 2 and the lamp holder 1. Each rotary locking structure 3 includes a locking groove 31 formed in the lampshade 2. A pressure plate 32 is provided inside the locking groove 31, and multiple sets of springs 33 are provided below the pressure plate 32 to allow the pressure plate 32 to move elastically within the locking groove 31 via the springs 33. Guide plates 321, which are rectangular in shape, are provided around the pressure plate 32. A guide groove 311 for sliding the guide plate 321 is provided inside the locking groove 31, allowing the pressure plate 32 to move linearly within the locking groove 31 via the guide plate 321. A slot 312 is provided at the upper part of the locking groove 31, which cooperates with a fixed locking plate 11 so that the fixed locking plate 11 is inserted into the locking groove 31 through the slot 312. An arc-shaped limiting groove 313 is provided on the side of the slot 312 for fixing the rotation of the locking plate 11, so that the locking plate 11 can slide through the limiting groove 313 to the tail end of the locking groove 31.

[0030] The lampshade 2 has a positioning groove 314 on the upper side of the tail end of the locking groove 31, which cooperates with the positioning post 12, so that the positioning post 12 is engaged in the positioning groove 314 to lock the position of the fixing plate 11.

[0031] The rotating locking structure 3 and the fixed locking plate 11 cooperate with each other so that the lampshade 2 can fix the fixed locking plate 11 through the rotating locking structure 3, thus completing the connection between the lamp holder 1 and the lampshade 2.

[0032] The working principle of the easy-to-disassemble LED downlight provided by this utility model is as follows:

[0033] During assembly, align the lampshade 2 with the connecting end face of the lamp holder 1. At this time, the fixing locking plates 11 on both sides of the connecting end face of the lamp holder 1 are aligned with the slot 312 of the locking groove 31 at the lampshade 2.

[0034] Push the lampshade 2 closer to the lamp holder 1 so that the fixing plate 11 is inserted into the locking groove 31 through the slot 312. As the lampshade 2 is pushed further in, the fixing plate 11 will contact the pressure plate 32 in the locking groove 31 and begin to apply pressure to the pressure plate 32.

[0035] Under pressure, the pressure plate 32 moves downward against the elastic force of the spring 33. At the same time, the guide plate 321 slides downward along the guide groove 311, ensuring that the pressure plate 32 can move downward smoothly and make room for the further insertion of the locking plate 11.

[0036] After the fixing plate 11 and the positioning pin 12 are fully inserted into the locking groove 31, rotate the lampshade 2. During the rotation, the fixing plate 11 slides along the arc-shaped limiting groove 313 on the side of the groove 312. As the rotation angle increases, the fixing plate 11 gradually moves to the tail end of the locking groove 31.

[0037] When the fixing plate 11 slides to the end of the locking groove 31, the positioning post 12 on its upper part aligns with the positioning groove 314 opened on the upper wall side of the lampshade 2 at the end of the locking groove 31. Under the elastic force of the spring 33, the pressure plate 32 pushes the fixing plate 11 upward, causing the positioning post 12 to engage in the positioning groove 314, thereby locking the position of the fixing plate 11. At this time, the lamp holder 1 and the lampshade 2 are connected through the tight cooperation of the rotating locking structure 3 and the fixing plate 11, and the LED downlight assembly is completed.

[0038] During disassembly, press the lamp holder 1 side and rotate the lamp cover 2 in the opposite direction. During this process, the positioning pin 12 of the fixing locking plate 11 disengages from the positioning groove 314. At the same time, as the rotation continues, the fixing locking plate 11 slides along the arc-shaped limiting groove 313 towards the groove opening 312.

[0039] When the fixed locking plate 11 slides to the position of the locking groove 31 near the groove opening 312, the elastic force of the spring 33 pushes the pressure plate 32 to move upward, so that the end of the fixed locking plate 11 pops out of the locking groove 31.

[0040] At this point, the lampshade 2 can be separated from the lamp holder 1 to complete the disassembly operation.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
