Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1-2 This utility model provides a waterproof and drop-resistant flashlight, including a shell body 1. The outer middle of the shell body 1 is provided with anti-slip texture, which can improve the friction when holding and prevent the flashlight from slipping and falling. The front end of the shell body 1 is connected to a front lamp cover 2. The outer side of the front lamp cover 2 is frosted, which can improve the friction and facilitate rotation. The rear end of the shell body 1 is provided with a rear cover 3.

[0023] The front end of the outer shell 1 is provided with a front light groove 11, and a set of light bulbs 12 are installed in the rear end of the front light groove 11. The middle of the outer shell 1 is provided with a battery slot 13 corresponding to the light bulbs 12. The battery slot 13 is provided with no less than two sets of battery modules 14, which can provide power to the light bulbs 12. The inner end of the outer shell 1 is provided with a cavity 15 near the battery slot 13. No less than two sets of reinforcing rings 16 are provided at equal intervals in the cavity 15, which can reduce the weight of the outer shell 1 and increase the strength of the outer shell 1, and improve the flashlight's drop resistance. The cavity 15 is provided with a desiccant, which can reduce the intrusion of moisture and keep the inside of the outer shell 1 dry, thus extending the life of the flashlight. The rear end of the outer shell 1 is provided with a connecting tube 17, and the rear end of the connecting tube 17 is connected to a compression washer 18.

[0024] Please see Figure 2-3 This utility model provides a waterproof and drop-resistant flashlight. The front cover 2 is threadedly connected to the outer side of the front lamp groove 11, and a gasket is provided at the front end of the front lamp groove 11. The front end of the front cover 2 is provided with a flange 21, which can improve the protective effect of the flange 21 on the front cover 2 and prevent the front cover 2 from being damaged by the impact when the flashlight is dropped. A set of protective films 22 are connected to the front end of the front cover 2, and a set of lenses 23 are in contact with the rear end of the protective film 22. The protective film 22 can protect the lenses 23 and prevent them from being scratched or damaged. When the front cover 2 is connected to the front lamp groove 11, the gasket at the front end of the front lamp groove 11 can contact the rear end of the lenses 23, which can not only fix the lenses 23, but also improve the sealing of the two sets of connections and improve the waterproof effect of the flashlight.

[0025] Please see Figure 2-4 This utility model provides a waterproof and drop-resistant flashlight. The front middle end of the back cover 3 is provided with a set of connecting grooves 31 corresponding to the connecting cylinder 17.
