Embodiment Construction

[0021] The present invention will be further elaborated below with reference to the accompanying drawings.

[0022] Please refer to the attached figure 1 to attach Figure 5 , in this embodiment, the anti-loosening tail cap mechanism includes: a tail cap 11, the tail cap 11 includes a cylindrical cover, the bottom of the cover is provided with a cover bottom, and the bottom of the cover is provided with a tail button for piercing 16 through holes. The outer cover conductive connection ring 12 located in the tail cover 11, a snap ring 18 is also provided between the inner wall of the tail cover 11 and the inner wall of the outer cover conductive connection ring 12, through the snap ring 18, so that the tail cap 11 is clamped on the outer cover conductive connecting ring 12 to limit the tail cover 11 to rotate arbitrarily around the axial direction without moving back and forth. Specifically, the snap ring 18 is a C-shaped snap ring, and the conductive connection ring 12 of t...

Abstract

The invention discloses an anti-loose tail cap mechanism and a lighting device thereof. The tail cap mechanism comprises: a tail cap, an outer cover conductive connecting ring disposed in the tail cap, and a snap ring disposed between the inner wall of the tail cap and the inner wall of the outer cover conductive connecting ring, which causes the tail cap to be locked behind the outer cover conductive connecting ring, and restricts the tail cap to rotate only axially. A spring is further disposed between the bottom of the tail cap and the right end of the outer cover conductive connecting ring. The bottom of the tail cap is further provided with a circular distribution first tooth. A second tooth corresponding to the first tooth is disposed on the outer cover conductive connecting ring. According to the anti-loose tail cap mechanism and the lighting device thereof, the outer cover conductive connecting ring and the spring the engagement of the tail cap and the outer cover conductive connecting ring is realized when the tail cap is pressed through the cooperation between the tail cap, the outer cover conductive connecting ring and the spring. Otherwise, the two are in a free state,thereby ensuring that the tail cap is not loose during use and can ensure good contact with the lighting.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to an anti-loosening tail cap mechanism and a lighting device thereof. Background technique [0002] Now there are many kinds of lighting equipment, but basically they all include three major components: lamp head, cylinder body and tail cap. There are also head and body connected together or cylinder body and tail cap connected together. For lighting equipment whose tail cap and body are separated, There are two kinds of conduction methods: thread conduction and tail end face conduction, both of which have their own advantages and disadvantages. For the threaded conductive structure, since its conductive surface cannot be oxidized, only the material body is exposed. Because the barrel body and tail cap need to replace the battery, after long-term rotation and friction, the worn surface of the material will be slag and blackened, which will affect the appearance, and it is ...
