[0030] The flashlight with anti-loosening charging provided by this invention includes an illumination component 100 and a cylindrical body 200. The top of the cylindrical body 200 is connected to the illumination component 100. The bottom of the cylindrical body 200 has a downward-facing bottom surface with two spaced-apart perforations. A longitudinally arranged copper component 220 is disposed in the perforation. The bottom of the copper component 220 is flush with the bottom surface. The cylindrical body 200 has a receiving cavity for the power supply core, which is connected to the perforations. The outer periphery of the cylindrical body 200 has a radially outward-expanding outer ring 210.

[0031] The aforementioned anti-loosening flashlight is inserted into the charging base 400 from top to bottom. The clamping member 410 on the charging base 400 swings to change the size of the charging slot, causing the outer expansion ring 210 to be fixedly engaged in the charging slot. When fixedly engaged, the charging connector on the charging base 400 accurately abuts against the copper part 220, achieving stable charging of the battery cell. In this way, the shell and the flashlight are securely connected during charging, preventing the flashlight from loosening.

[0041] In a preferred embodiment, the illumination assembly 100 includes a lamp head 1000 and a lamp head cover 110, which are connected to the lamp head 1000 via a snap-fit ​​connection. The bottom of the lamp head 1000 is movably connected to the cylinder 200 via a connector 300, allowing the lamp head 1000 to swing up and down with the connector 300 as a fulcrum. This snap-fit ​​connection eliminates the need for screws 250, resulting in a clean and simple product appearance.

[0042] Specifically, the connector 300 can be a hinge, enabling hinge-like movement. The connector 300 can also be a pivot, enabling pivot-like movement. The connector 300 can also be a universal joint, etc., enabling flexible rotation.

[0043] An upper sealing ring 111 is fixed between the lamp holder 1000 and the lamp holder cover 110. The upper sealing ring 111 is in a compressed state. This improves the overall structural tightness and makes the overall structure more compact.

[0044] In some embodiments, an expansion ring 210 is formed at the bottom of the cylinder 200, and the expansion ring 210 is integrally formed with the cylinder. This results in a simple appearance and easy handling.

[0045] In some embodiments, the outer periphery of the cylinder 200 is provided with a clamp 205 and a power indicator light.
