Detailed Implementation

[0017] like Figures 1 to 5 The aforementioned waterproof zoomable lamp structure includes a lamp body 10, which houses an optical zoomable assembly 20 and a light source assembly 30. The optical zoomable assembly 20 includes a lens 21, a drive shaft 22, a rotating guide tube 23, and a focusing knob 24. The light source assembly 30 is located on one side of the lens 21 and includes a light source 31 and a light source mounting portion 32. One end of the drive shaft 22 passes through the light source mounting portion 32 and is connected to the lens 21. The other end of the drive shaft 22 is provided with a rotating member 25, which is provided with a rotating limit screw 26. The rotating limit screw 26 is located in the guide groove 27 of the rotating guide tube 23. The end of the rotating guide tube 23 away from the drive shaft 22 is connected to the focusing knob 24 on the outside of the lamp body 10.

[0018] When in use, the light from the light source 31 shines outward through the lens 21. By rotating the focusing knob 24 on the outside of the lamp body 10, the rotating guide tube 23 is rotated. The guide groove 27 in the rotating guide tube 23 pushes the rotating limit screw 26 to move in the guide groove 27, thereby moving the lens 21. The distance between the lens 21 and the light source 31 is adjusted to achieve zoom.

[0019] The front end of the lamp body 10 is provided with a front pressure ring 11, and the front pressure ring 11 is provided with a waterproof rubber ring 12 and a glass 13. The waterproof rubber ring 12 is located between the glass 13 and the front pressure ring 11. The waterproof rubber ring 12 can prevent rainwater from entering the interior of the lamp body from the front end of the lamp body 10.

[0020] The lamp body 10 has a rear cover 14 at its rear end, and a second waterproof rubber ring 15 is provided between the rear cover 14 and the lamp body 10. The second waterproof rubber ring 15 can prevent rainwater from entering the lamp body through the gap between the rear cover 14 and the lamp body 10.

[0021] One end of the rotating guide tube 23 passes through the rear cover 14 and is connected to the focusing knob 24. A waterproof seal 16 is provided on the outside of the rotating guide tube 23 in the rear cover 14. The waterproof seal 16 can prevent rainwater from entering the lamp body through the gap between the rotating guide tube 23 and the rear cover 14.

[0022] The back cover 14 is screwed to the lamp body 10 via a connecting component 17. A third waterproof rubber ring 18 is provided between the connecting component 17 and the back cover 14. The third waterproof rubber ring 18 can prevent rainwater from entering the lamp body through the gap between the connecting component 17 and the back cover 14.

[0023] In summary, the waterproof zoom lamp structure of this utility model allows for zooming by adjusting the distance between the lens 21 and the light source 31 by rotating the focusing knob 24. The front and rear ends of the lamp body 10 are equipped with several waterproof rubber rings, which can prevent rainwater and other foreign objects from entering the lamp body, thereby achieving a good waterproof effect and extending the service life of the lamp.
