Embodiment Construction

[0026] The flashlight will be further described below in conjunction with the drawings and embodiments.

[0027] Such as Figure 1~4 The flashlight shown includes a main housing 10, a lamp cap housing 20, a cam plate 30, a rotating ring 40, a light source assembly 50, a limiting plate 60, a transmission rod 70, a spring 80, and a movement transmission plate 90. A reflector cup 22 is fixed on the lamp housing 20.

[0028] A cavity with an opening 12 is formed inside the main housing 10, and an external thread 14 is provided on the outside of the opening 12 of the main housing 10.

[0029] The lamp holder housing 20 is cup-shaped, and the inner wall is provided with an internal thread 24.

[0030] The main housing 10 and the lamp cap housing 20 are fixed together by an external thread 14 and an internal thread 24.

[0031] The cam plate 30 is in the shape of a disc. One side surface is flat and is in contact with the bottom surface of the cavity of the main housing 10, and the other side...

Abstract

The invention discloses a flashlight, which comprises a main shell, a cup cover-shaped lamp holder shell, a reflection cup fixed on the lamp holder shell, a disc-shaped cam disc, a rotating ring sheathed on the periphery of the camp disc, a light source assembly, a limiting plate, a transfer bar, a spring and a circular ring-shaped movement transfer plate. Driven by rotation of the cam disc, the transfer bar moves along an axial line direction of the flashlight, so that the movement transfer plate can drive the light source assembly to move, and then the light source assembly can move along the axial line direction of the flashlight, meanwhile, the reflection cup is fixed on the lamp holder shell and remains relative rest, as a result, the light source assembly and the reflection cup have relative displacement therebetween, in this way, the flashlight can be adjusted to condense light or diffuse light; in comparison with a traditional flashlight of which light distribution is adjusted by moving the reflection cup, the flashlight disclosed by the invention has better sealing performance at the lamp holder.

Description

【Technical Field】 [0001] The invention relates to lighting equipment, in particular to a flashlight. 【Background technique】 [0002] The traditional flashlight adjusts the light distribution by moving the reflector. The flashlight adopting this light distribution method causes poor sealing at the lamp cap due to the rotating reflector. [Content of the invention] [0003] Based on this, it is necessary to provide a flashlight with better sealing at the lamp cap. [0004] A flashlight comprising a main shell, a cap-shaped lamp cap shell, a reflector cup fixed on the lamp cap shell, a disc-shaped cam disc, a rotating ring sleeved on the outer periphery of the cam disc, and a light source Components, limit plates, transmission rods, springs and circular movement transmission plates; [0005] A cavity with an opening is formed inside the main housing; the lamp cap housing is fixedly connected to the main housing; a side surface of the cam plate is a planar structure and is in contact wit...
