[0017] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0018] First embodiment:

[0019] See also Figure 1 and Figure 3 FIG. 2 is a schematic diagram of the structure of the first embodiment of the present application. In the first embodiment, the lampshade buckle structure comprises a lamp body 1 , a cover body 2 and a plurality of fastening structures 3 .

[0020] The two side walls of the lamp body 1 are provided with a plurality of limit rotation grooves 11 for clamping the first rotation axis. The top of the outer wall of each limit rotation groove 11 is provided with an inwardly inclined inclined surface 111, and the top is bent inwardly as a whole to form a first hook body 112.

[0021] The outer side surface of the cover body 2 is provided with a clamping groove corresponding to the limit rotation groove so as to be engaged with the third hook body of the fastening structure 3.

[0022] The fastening structure 3 includes a buckle tab 31 and a buckle body 32. Figure 2 shown.

[0023] The buckle small piece 31 includes a first rotating shaft 311, a small piece body 312 and a second rotating shaft 313. The first rotating shaft 311 is arranged in the limit rotating groove 11, and the front end of the small piece body 312 is provided with a fourth hook body 3121, which is hooked on the first rotating shaft 311 through the fourth hook body, so as to facilitate assembly. The second rotating shaft 313 is pivotally connected to the buckle body 32. The buckle small piece 31 can rotate relative to the lamp body through the first rotating shaft 311; the buckle small piece can rotate relative to the buckle body 32 through the second rotating shaft 313. Two reinforcing pieces 314 are provided on the lower surface of the small piece body 312 near the first rotating shaft 311 to increase the strength of the small piece body and prevent the small piece body and the first rotating shaft from breaking after multiple engagements.

[0024] The front end of the lower surface of the buckle body 32 forms two opposite connecting ends 321. The connecting ends 321 are respectively connected to the two ends of the second rotating shaft 313. The middle section of the buckle body 32 is provided with a bent clamping position 322, and the lower section of the buckle body is bent downward. The bent clamping position 322 fits the inclined surface 111 at the top of the outer wall of the limiting rotating groove 11. At the same time, the side edge 3211 between the bent clamping position 322 and the connecting end 321 and the side wall of the connecting end 321 on the corresponding side form a second hook body 323 that is engaged with the first hook body 112. When fastened, the lower section of the buckle body 32 fits on the lamp body, and the second hook body 323 hooks the first hook body 112, which increases the tightness of the connection and shares the gravity on the buckle body 32 to the first hook body 112, that is, the lamp body, thereby extending the service life of the buckle. The lower end of the buckle body 32 is provided with a third hook body 324 that matches the clamping slot.

[0025] Second embodiment:

[0026] See also Figure 4-Figure 5 As shown, in the second embodiment, one side of the two connecting ends 321 facing the buckle small piece 31 is respectively provided with an elastic damping structure 4. The two sides of the elastic damping structure 4 are respectively provided with an inclined guide edge 41 and 42. The elastic damping structure 4 normally interferes with the lower surface of one side of the small piece body 312 with one of the guide edges 41. At this time, Figure 4 As shown, the guide edge 41 interferes with the small piece body 312 so that it cannot fall freely due to gravity during installation, which increases the convenience of installation. When the applied force is greater than the resistance of the elastic damping structure, the small piece body 312 squeezes into the middle of the elastic damping structure along the guide edge 41 on the corresponding side, and then folds to the other side of the elastic damping structure 4, and the other guide edge 42 interferes with the upper surface of the other side of the small piece body 313. At this time, due to the effect of the guide edge 42, the small piece body 313 is tightly attached to the buckle body 32 and is not easy to separate.

[0027] like Figure 2 and Figure 3 As shown, a first fastening hole 325 is formed on the buckle body 32, and a second fastening hole 315 is correspondingly formed on the small piece body 31. The first fastening hole and the second fastening hole are connected to the lamp body through bolts.

[0028] A raised sealing portion 326 with a perforation is provided on one side of the first fastening hole 325 corresponding to the second fastening hole 315. When the buckle body overlaps with the small piece body, the raised sealing portion is inserted into the second fastening hole, and the bolt passes through the perforation. This can increase the airtightness of the lamp body, while reducing the movable position difference of the bolt, thereby increasing the convenience of tightening the bolt.

[0029] In summary, the buckle structure of the present application simplifies the structure, and the fastener only requires a buckle plate and a buckle body, which is easy to install; a second hook is formed on the buckle body to engage with the first hook on the lamp body, which shares the gravity of the lampshade on the lamp body, and the overall structural stability is enhanced, making it more compact and beautiful; at the same time, a damping structure with a guide edge is added to limit the movement of the buckle body relative to the buckle plate, which is convenient for avoiding natural drooping during installation and increases the tightness when engaged.

[0030] The above-described embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Equivalent changes and modifications made to the present invention by those skilled in the art should all fall within the scope of the claims attached to the present invention.
