The lower edge of the lamp base extends outward to form an upper flange, and the upper edge of the lampshade extends outward to form a lower flange. One side of the lower flange is hinged to the upper flange via a steel wire shaft. A snap block is provided at the other edge of the lower flange. A corresponding snap foot is machined on the edge of the upper flange, and the snap foot and the snap block are matched and snapped together. In the three-proof lamp, the lamp base and the lampshade are hingedly mounted on one side of the steel wire shaft. A rotating shaft at the lower end of the steel wire shaft is rotatably connected to the upper flange of the lampshade. A hook at the upper end of the steel wire shaft extends into a guide groove on the side of the lamp base and cooperates with a limit buckle to form a movable snap connection. When the lampshade is opened for maintenance, the hook can slide down along the channel formed between the limit buckle and the inner wall of the guide groove to the bottom wall of the guide groove, facilitating maintenance. When closed, the hook can slide up along the channel formed between the limit buckle and the inner wall of the guide groove to the top of the limit buckle, achieving a snap connection effect, making it more convenient to use.

DETAILED DESCRIPTION

[0025] like Figure 3 As shown, in embodiment 1 of the present invention, a three-proof lamp assembly that is easy to repair includes a lamp base 1, a lampshade 2 that is buckled into the lower part of the lamp base 1, the lower edge of the lamp base 1 extends outward to form an upper flange 11, the upper edge of the lampshade 2 extends outward to form a lower flange 22, one side of the lower flange 22 is hinged to the upper flange 11 through a steel wire shaft 3, an integrally formed positioning block 23 is provided at one edge of the lower flange 22, a positioning groove 231 is machined at the lower part of the positioning block 23, the steel wire shaft 3 is installed in the positioning groove 231, and the top edge of the upper flange 11 is correspondingly machined with a guide groove 1 3. After the two ends of the steel wire shaft 3 are bent, they extend from bottom to top into the guide groove 13. The steel wire shaft 3 includes a rotating shaft 32. The rotating shaft 32 is matched and installed in the positioning groove 231. The lower part of the positioning groove 231 forms a guide opening 232. The minimum width of the guide opening 232 is smaller than the outer diameter of the steel wire shaft 3. The two ends of the rotating shaft 32 are bent twice to form a hook 31. The inner wall of the guide groove 13 is processed with a limit buckle 14 that is buckled with the hook 31. The limit buckle 14 is in an inverted triangle shape. A channel for the hook 31 to slide is formed between the limit buckle 14 and the inner wall of the guide groove 13 (see Figure 4 ), a buckle block 24 is provided at the other side edge of the lower flange 22, and a buckle foot 16 is correspondingly processed at the edge of the upper flange 11, and the buckle foot 16 is matched with the buckle block 24 (see Figure 5 ), a card slot 15 is processed above the buckle foot 16, the upper part of the buckle block 24 extends into the card slot 15, the buckle foot 16 is buckled and connected with the lower part of the buckle block 24, the right side of the buckle block 24 is processed to form an inclined surface Ⅰ241, and the left side of the buckle foot 16 is correspondingly processed to form an inclined surface 161 that matches the inclined surface Ⅰ241, a groove 12 is processed at the bottom of the upper flange 11, and a sealing strip 4 is installed in the groove 12, and a convex portion 21 is formed on the top of the lower flange 22, and the upper end of the convex portion 21 presses the sealing strip 4, so as to form a closed space inside the lamp base 1 and the lampshade 2.

[0026] The bottom of the lamp and one side of the lampshade are hinged with a steel wire shaft, and the rotating shaft at the bottom of the steel wire shaft is rotatably connected to the upper flange of the lampshade. The hook at the top of the steel wire shaft extends into the guide groove at the side of the bottom of the lamp and cooperates with the limit buckle to form a movable buckle. When the lampshade is opened for maintenance, the hook at the top of the steel wire shaft can slide down to the bottom wall of the guide groove along the channel formed between the limit buckle and the inner wall of the guide groove (such as Figure 6 When the lampshade is closed, the hook on the upper part of the wire shaft can slide up along the channel formed between the limit buckle and the inner wall of the guide groove to the top of the limit buckle, achieving a buckling connection effect, so that the upper flange and the lower flange on this side are fully in contact to form a closed space, which is more convenient to use.

[0027] When maintenance is needed, just pry apart the buckle feet on one side of the lamp base and the lamp holder to separate the buckle feet from the buckle block. The lampshade on this side will flip downward with the rotating shaft as the center under the action of its own gravity. The hook on the upper part of the wire shaft will slide out of the limit buckle after being pulled downward, and slide down along the channel formed between the limit buckle and the inner wall of the guide groove to the bottom wall of the guide groove. The lampshade can be fully opened and formed into a hanging state by relying on the wire shaft. When the maintenance is completed and it needs to be closed, just hold the bottom of the lampshade and press upwards. The inclined surface on the side of the buckle foot slides in coordination with the inclined surface Ⅰ on the side of the buckle block, the upper part of the buckle block is inserted into the slot above the buckle foot, and the bottom of the buckle block is buckled with the top of the buckle foot. The hook on the upper part of the wire shaft slides along the channel formed between the limit buckle and the inner wall of the guide groove to the top of the limit buckle, achieving the effect of buckling connection, so that the upper flange and the lower flange on this side are fully in contact. At the same time, the convex part on the lampshade presses the sealing strip in the groove at the bottom of the lamp, forming a closed space at the bottom of the lamp and inside the lampshade to ensure the waterproof effect.

[0028] Example 2: Compared with Example 1, the inner walls on both sides of the guide groove 13 are smooth and no limit buckle 14 is provided. The hook 31 on the upper part of the wire shaft 3 can slide up and down directly in the guide groove 13. The wire shaft 3 mainly plays the role of a rotating shaft and suspension. Compared with Example 1, it lacks the function of fastening the lamp base 1 and the lampshade 2. Accordingly, buckle blocks 24 can be provided at the edges of the lower flange 22 on both sides of the lampshade 2, and buckle feet 16 are correspondingly provided at the edges of the upper flange 11 on both sides of the lamp base 1. The buckle feet 16 are fastened with the buckle blocks 24 to form a closed space.

[0029] When in use, just bend the buckle feet on both sides of the lamp base and the lampshade outward to separate them from the buckle block. After the hook loses the pulling force of the buckle feet, it slides down to the bottom of the guide groove. The lampshade as a whole flips downward with the rotation axis as the center and opens completely. When closing, just press the lampshade upward to make the buckle feet engage with the buckle block.

[0030] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
