[0032] Please see Figures 1 to 5This embodiment discloses a quick-change accessory device applied to a track light, comprising: a light body 1, an accessory module 2, and an elastic adaptive module 3. The light body 1 includes a bottom shell module 11 and a lamp cover plate 12 detachably snapped onto the bottom shell module 11. The lamp beads within the bottom shell module 11 are regularly spaced with gaps a, and a first slot b1 is formed on one side of each lamp bead. A spring clip A formed on the accessory module 2 engages with the first slot b1. A guide channel c1 is formed at the bottom of the accessory module 2, and a limiting ring protrudes from the lower end of the guide channel c1 towards the center. The elastic adaptive module 3 includes: guide posts d1 corresponding to support blocks 31 penetrating the guide channel c1, sleeved on each guide post d1, and located between the guide post d1 and the guide channel c1. The elastic element 32 between the guide post d1 and the guide post d1 are connected to the fixing element 33, and the cap and the gasket 34 of the guide channel c1 are connected through the fixing element 33 and abut against the fixing element 33 and the guide channel c1 respectively. When the support block 31 is pressed down, the elastic element 32 is elastically compressed and each guide post d1 pushes the corresponding fixing element 33 to guide the corresponding gap a1. Specifically, the outer wall of the guide post d1 abuts against the limiting ring.

[0033] In a preferred embodiment, a receiving cavity is formed on the bottom shell module 11, and the LED beads are installed in the receiving cavity. The gap a1 is formed by the central LED bead and its adjacent LED beads; specifically, every four adjacent LED beads form the gap a1. More specifically, a first buckle is formed on one side of the receiving cavity, facing the lampshade plate 12, and a matching buckle portion is formed on the lampshade plate 12. After assembling the elastic adaptive module 3 and the accessory module 2, the lampshade plate 12 is snapped into the bottom shell module 11. The first snap gap b1 is formed by the fence formed around the LED beads and one side of the buckle portion.

[0034] The accessory module 2 in the preferred embodiment includes: an accessory 21 with a recessed groove in the middle; a spring clip A formed on one side of the groove; a retaining plate B protruding from the other side of the groove; and a glass plate 22 including one end abutting against the spring clip A and the other end being secured by the retaining plate B. Specifically, the spring clip A is V-shaped, and a second retaining plate A1 is protruding from one side of the spring clip A. The second retaining plate A1 and the retaining plate B face each other and jointly engage and limit the glass plate 22. More specifically, an anti-slip structure A2 is formed on the surface of the spring clip A above the second retaining plate A1. In use, pressing the anti-slip structure A2 elastically compresses the spring clip A, engaging one end of the glass plate 22 into the retaining plate B and the other end into the second retaining plate A1. Releasing the anti-slip structure A2 secures the glass plate 22. Furthermore, the side of the retaining plate B that engages against the glass plate 22 is an inclined guide surface. The design of the inclined structure gives the product a better automatic guiding function.

[0035] In a preferred embodiment, the elastic element 32 is a spring, and the fixing element 33 is a screw. The screw passes through the washer 34 and is inserted into the guide post d1. The spring is sleeved on the outer periphery of the guide post. In use, when the assembled elastic adaptive module 3 is moved through the guide channel c1 towards the gap a, corresponding to the guide post d1, the downward pressure interacts with the limiting ring, causing the spring to elastically compress.

[0036] During assembly, accessory 21 is fixed to the bottom shell module 11 via spring clip A through the first slot b1. Then, glass plate 22 is fixed to accessory 21 via spring clip A. While fixing glass plate 22, elastic adaptive module 3 automatically adapts and fills the gap in bottom shell module 11, so that this product has the function of quick assembly and disassembly of accessory module 2.

[0037] As can be seen from the above description, this utility model achieves the function of quick disassembly and assembly and replacement of parts by designing the bottom elastic adaptive module 2.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
