Embodiment Construction

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

[0027] Such as Figure 1~4 The flashlight shown includes a main housing 10 , a lamp base 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 moving transmission plate 90 . A reflector 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 outside 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 base housing 20 are fixed together by external threads 14 and internal threads 24 .

[0031] The cam disc 30 is disc-shaped, one side is flat and contacts with the bottom surface of the cavity of the main housing 10, and the other side is a cur...

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 using this light distribution method has poor sealing at the lamp head due to the rotation of the reflector. 【Content of invention】 [0003] Based on this, it is necessary to provide a flashlight with better sealing performance at the lamp cap. [0004] A flashlight, comprising a main shell, a cap-shaped lamp cap shell, a reflective cup fixed on the lamp cap shell, a disc-shaped cam plate, a rotating ring sleeved on the outer periphery of the cam plate, and a light source Components, limiting plates, transfer rods, springs and circular moving transfer plates; [0005] A cavity with an opening is formed inside the main housing; the lamp holder housing is fixedly connected to the main housing; one side of the cam plate is a plane structure and co...
