Description

Technical Field

[0001] This utility model relates to the field of LED flashlight technology, specifically to an LED flashlight with good waterproof performance. Background Technology

[0002] With technological advancements, small and power-efficient LEDs have emerged. LED flashlights are a new type of flashlight that uses LEDs (light-emitting diodes) as their light source. Because LEDs offer high brightness, low power consumption, long lifespan, and small size, they are an ideal choice for portable lighting. Compared to incandescent bulbs, LED flashlights generally have longer lamp and battery lifespans, largely due to their lower power consumption and operating temperature. However, typically, the beam intensity of an LED flashlight is lower than that of a regular incandescent flashlight. A typical LED flashlight produces a wide, unfocused beam, or a small, high-intensity spot in the center surrounded by a wide, lower-intensity patch.

[0003] LED flashlights are mostly used in outdoor environments, but existing LED flashlights do not have corresponding waterproof structures. If they are dropped into puddles or used in rainy or snowy weather, external moisture can easily enter the LED flashlight, causing it to malfunction and making it inconvenient for staff to use.

A collar 1202 is fitted onto the outer ring of the retaining ring 1201 and fixedly connected to the right side of the lamp head 31. A retaining protrusion 1203 is provided on the right side of the retaining ring 1201, which is fixedly connected to the left side of the inner ring of the waterproof housing 1101 and slidably connected to the outer ring of the handle 3. The locking component 13 includes a first fixing cylinder 1301, which corresponds to... The cam 1203 is fixedly connected to the inner ring of the collar 1202. The slide cylinder 1302 is slidably connected inside the fixed cylinder 1301. The compression spring 1303 is fixedly connected to the top of the slide cylinder 1302. The positioning rod 1304 is fixedly connected to the bottom of the slide cylinder 1302. The positioning rod 1304 passes inward through the waterproof sleeve 1101 and the collar 1201 and is engaged inside the outer ring of the handle 3. The pulling component 14 includes a telescopic slide rod 1401. The telescopic slide rod 1401 is fixedly connected to the inner outer side of the slide cylinder 1302. The telescopic slide rod 1401 is slidably connected to the inner outer side of the fixed cylinder 1301. The pull rod 1402 is fixedly connected to the outer side of the telescopic slide rod 1401.

[0030] Furthermore: The waterproof cover 1101 is fitted onto the outer ring of the handle 3 to protect the handle 3, preventing the handle 3 from directly contacting the external environment and effectively blocking moisture from the external environment. This provides waterproof protection for the handle 3, ensuring that it will not malfunction due to falling into water or rain entering the handle 3 during use, thus facilitating its use by staff.

[0031] Example 2

[0032] See Figures 1 to 4Furthermore, based on Embodiment 1, the positioning mechanism 2 includes a reset component 21 and a positioning component 22. The reset component 21 is located on the outer ring of the connecting component 12, to the left of the locking component 13, and the positioning component 22 is located on the inner side of the outside of the reset component 21.

[0033] The reset assembly 21 includes a second fixed cylinder 2101, which is fixedly connected to the outer ring of the collar 1202 at the position corresponding to the first fixed cylinder 1301. A second sliding cylinder 2102 is slidably connected inside the second fixed cylinder 2101. A reset spring 2103 is fixedly connected to the left side of the second sliding cylinder 2102. The positioning assembly 22 includes a movable sliding rod 2201, which is fixedly connected to the outside of the second sliding cylinder 2102. The movable sliding rod 2201 is slidably connected to the inside of the outside of the second fixed cylinder 2101. A sleeve 2202 is fixedly connected to the outside of the movable sliding rod 2201. The sleeve 2202 is sleeved on the outer ring of the pull rod 1402.

[0034] Furthermore: Under the action of the return spring 2103, the slide cylinder 2102 moves the sleeve 2202 to the right through the moving slide rod 2201, so that the sleeve 2202 fits onto the outer ring of the pull rod 1402 to complete the positioning of the pull rod 1402. This prevents the positioning latch 1304 from moving on its own to release the positioning of the waterproof cover 1101, ensuring the stability of the waterproof cover 1101 after installation and improving the protective effect of the waterproof cover 1101 on the handle 3 after installation.

[0035] In actual operation, when this device is in use and the waterproof housing 1101 needs to be installed, the operator first moves the waterproof housing 1101 to the right side of the handle 3, then rotates the waterproof housing 1101 to align the retaining ring 1201 with the outer ring of the handle 3. Next, the operator moves the waterproof housing 1101 to the left, fitting it onto the outer ring of the handle 3, until the waterproof housing 1101 can no longer be moved to the left. At this point, the operator moves the sleeve 2202 to the left. After the sleeve 2202 moves to the left, the operator presses the corresponding pull rod 1402 inward. The inward movement of the pull rod 1402 is achieved through the telescopic slide rod 1401 and the slide cylinder. 1302 drives the positioning rod 1304 to move inward. The positioning rod 1304 moves inward and passes through the waterproof sleeve 1101 and the retaining ring 1201 to engage with the outer ring of the handle 3. Then, the operator releases the limit on the sleeve 2202. At this time, the slide cylinder 2102, under the action of the return spring 2103, moves the sleeve 2202 to the right through the moving slide rod 2201. The sleeve 2202 moves to the right and engages with the outer ring of the pull rod 1402. At this time, the positioning of the positioning rod 1304 is completed. Then, the above operation is repeated for multiple pull rods 1402 and sleeves 2202. At this time, the installation of the waterproof sleeve 1101 is completed.
