[0021] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0022] like Figures 1-5 The illustrated waterproof lampshade structure includes a lamp base 1 and a lampshade 2 that covers the light outlet of the lamp base 1. The mating surfaces of the lamp base 1 and the lampshade 2 are a first mounting plane 3 and a second mounting plane 4, respectively. A retaining ring 5 extending into the lamp base 1 is provided on the second mounting plane 4. An L-shaped screw groove 6 is provided on the retaining ring 5. A locking block 7 that can engage with the L-shaped screw groove 6 is provided on the inner side wall of the lamp base 1. The upper edge of the retaining ring 5 is provided with a groove. The L-shaped screw-in groove 6 is formed by providing an extension plate 9 on one side of the groove. The L-shaped screw-in groove 6 includes a vertical groove 10 and a horizontal groove 11. When installing the lampshade 2, the L-shaped screw-in groove 6 corresponds to the locking block 7 and is inserted. Then, by rotating the lampshade 2, the locking block 7 is inserted into the L-shaped screw-in groove 6, thereby realizing the connection and installation of the lampshade 2 and the lamp base 1, which facilitates the disassembly and installation of the lampshade 2.
[0023] Furthermore, an elastic pressing member is also provided on the extension plate 9. After the lamp cover 2 is closed with the lamp base 1, the elastic pressing member abuts against the inner bottom wall of the lamp base 1, thereby allowing the extension plate 9 to press the locking block 7 tightly, improving the stability of the locking block 7 when it is engaged with the L-shaped rotary groove 6.
[0024] In addition, by providing a waterproof sealing component between the first mounting plane 3 and the second mounting plane 4, the waterproofness of the lampshade 2 and the lamp base 1 after installation and fixation is greatly improved.
[0025] See Figure 2 , Figure 4 , Figure 5 As shown, the elastic pressing member includes a cylinder 21 disposed on the extension plate 9. A circular groove 22 is provided on the end face of the cylinder 21. A spring 23 and a steel ball 24 are disposed in the circular groove 22. The steel ball 24 is pressed against the inner bottom wall of the lamp base 1 by the action of the spring 23.
[0026] Further, the outer wall of the cylinder 21 protrudes outside the extension plate 9 to form a positioning flange 31, and a first positioning groove 32 and a second positioning groove 33 are arranged on the inner side wall of the lamp base 1 in a spaced manner and are matched with the positioning flange 31; when the locking block 7 is clamped into the vertical slot 10, the positioning flange 31 is correspondingly arranged in the first positioning groove 32 at this time, and then when the locking block 7 is rotated to be clamped in the horizontal slot 11, the positioning flange 31 is clamped in the second positioning groove 33 at this time, further fixing the lampshade 2 and improving the stability of the lampshade 2 after installation.
[0027] In order to facilitate the locking block 7 to be clamped into the vertical slot 10, the opening edge angle of the vertical slot 10 is an inclined angle structure 41.
[0028] Referring to Figure 3 As shown, the waterproof sealing assembly comprises a first convex ring 51 arranged on the inner side edge of the first mounting plane 3, a first concave ring 52 arranged on the second mounting plane 4 and matched with the first convex ring 51, and a first sealing ring 53 arranged in the first concave ring 52; the waterproof sealing assembly further comprises a second convex ring 61 arranged on the outer side edge of the second mounting plane 4, a second concave ring 62 arranged on the first mounting plane 3 and matched with the second convex ring 61, and a second sealing ring 63 arranged in the second concave ring 62.
[0029] Thus, through the double waterproof cooperation of the first sealing ring 53 and the second sealing ring 63, the sealing performance of the lampshade 2 after assembly is greatly improved.
[0030] The basic principle and main characteristics of the present application and the advantages of the present application are shown and described above in combination with the drawings, and those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the present application, and various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
