torch

Abstract

A flashlight comprises a barrel, a battery cover component and a limit structure. The battery cover component comprises a tail cover. At least part of the tail cover is inserted into the barrel. The outer wall of the tail cover is provided with a limit slot. The limit structure comprises a fitting tube, a limit pin and a return elastic member. The fitting tube comprises a tube body and a butt part at the top end of the tube body. The fitting tube is fixedly connected with the barrel. The limit pin comprises a shank and a limit part arranged on the shank. One end of the shank penetrates the tube body. The return elastic member sleeves the shank and elastically abuts between the limit part and the butt part. The limit part abuts to the outer wall of the barrel under the action of the return elastic member. When the tail cover is fitted to one end of the barrel, the other end of the shank is inserted into the limit slot so that the tail cannot move relative to the barrel. A battery of the flashlight is convenient to mount and demount, and the tail cover is avoided dropping when connection threads fail.

Description

【Technical field】 [0001] The invention relates to a lighting device, in particular to a flashlight with a position-limiting structure. 【Background technique】 [0002] Flashlight is a common lighting tool in people's daily life. The tail cap of the torch is usually detachably connected to the lamp barrel to facilitate the removal of the tail cap to replace the battery contained in the lamp barrel. The lamp tube of a traditional flashlight is usually cylindrical, and the battery is a cylindrical alkaline battery. The tail cap is connected to the lamp tube through a threaded connection, so that when the battery needs to be replaced, just turn the tail cap. [0003] However, the flashlight usually includes a lamp tube, a battery and a tail cap. The battery is accommodated in the lamp tube, and the tail cap is partially accommodated in an open end of the lamp tube and is threadedly connected with the lamp tube to close the open end. When the connecting thread between the tail c...

AI Technical Summary

Problems solved by technology

When the connection thread between the tail cap and the lamp tube fails, the tail cap is easy to fall off from the lamp tube

[0004] Although there is currently a limiting structure for the flashlight used to limit the battery or tail cap, however, this limiting structure usually uses threaded fasteners to limit the tail cap, which requires special tools when installing or removing the battery. Resulting in more cumbersome installation or removal
