[0002] A zoom flashlight is a lighting tool that can change the degree of light beam convergence by moving the head cover or adjusting the optical system, thereby adjusting the light spot size and irradiation distance. This type of flashlight is usually used in outdoor activities, search and rescue, tactical applications and other fields, and is favored by users for its flexibility and versatility.

[0003] A Chinese utility model with patent number CN208204605U discloses a zoom flashlight, which can drive the lamp beads on the lamp holder to move up and down by infinitely rotating the zoom component in one direction, thereby changing the distance between the lamp beads and the lens to achieve infinite continuous zoom. At the same time, the zoom component rotates around the lamp head connector, and the rotation will not change the length of the flashlight, so the flashlight itself can always be kept in the most coordinated length ratio.

[0004] Although the device achieves the zoom effect by moving the head cover, the mobility of the head cover sacrifices the waterproofness and sealing of the product. External dirt can easily enter the connection between the head cover and the lens through the rotating grooves, causing dirt inside the lens and affecting the lighting effect of the flashlight.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0022] Reference Figure 1-4 A flashlight lamp holder protective shell comprises a flashlight body 1, a protective part and a sealing part 8.

[0023] A push switch 2 is provided at one end of the flashlight barrel 1, and a lamp bead 3 is provided at the other end of the flashlight barrel 1. The flashlight barrel 1 is an existing structure, and its internal structure is not described in detail. The lamp bead 3 is inside the protective member, and the push switch 2 is outside the protective member.

[0024] The protective part includes an upper sleeve 4 and a lower sleeve 5. The upper sleeve 4 and the lower sleeve 5 are in a connected state, and there is a cavity inside them. The lower sleeve 5 is slidably connected to the flashlight barrel 1. The bottom surface of the lower sleeve 5 is provided with a mounting groove 6. A sealing sleeve 7 is installed in the mounting groove 6, and the sealing sleeve 7 is sleeved on the flashlight barrel 1. The sealing sleeve 7 is installed at the contact position between the lower sleeve 5 and the flashlight barrel 1, which can improve the sealing between the lower sleeve 5 and the flashlight barrel 1. A limit component for limiting the movement of the flashlight barrel 1 is provided in the upper sleeve 4.

[0025] The limiting component includes a linkage block 13, and the linkage block 13 is fixedly connected to one end of the flashlight barrel 1. A hemisphere 14 is fixedly connected to the linkage block 13. An elastic rod 15 is installed on the inner wall of the lower sleeve 5. The number of the elastic rod 15 is at least one. When the hemisphere 14 on the linkage block 13 moves, the hemisphere 14 squeezes the elastic rod 15, which causes a certain deformation of the elastic rod 15, so that the hemisphere 14 can be moved to the bottom of the elastic rod 15. At this time, the elastic rod 15 will also restore its original state under its own elasticity, thereby limiting the hemisphere 14.

[0026] A guide rod 16 is slidably connected inside the linkage block 13, one end of the guide rod 16 is fixedly connected to the lower sleeve 5, and the other end of the guide rod 16 passes through the linkage block 13 and is installed with a limit plate 17.
