Description

Technical Field

[0001] The utility model relates to the technical field of soft light boxes, in particular to a soft light box support rod connection structure. Background Art

[0002] In order to make the light softer during shooting, photographers usually install a softbox in front of the photographic lamp. The softbox has gradually evolved from the earliest umbrella-like structure with a pole. The function of the softbox is to soften the harsh light and make the light quality softer. Its principle is to diffuse the original light through one or two layers on the basis of ordinary light sources, so that the irradiation range of the original light becomes wider and becomes diffuse light. The conventional storage methods on the market are relatively large in size, which is not convenient for storage and transportation.

[0003] A Chinese patent document CN102902134B discloses a foldable softbox, comprising: a support frame; an annular main body, the middle of the annular main body is hollow, a groove is arranged around the front periphery, the middle of the annular main body is hollow, a plurality of support rod sleeves, the connection ends of which are inserted into the grooves from the sides of the annular main body; a plurality of support rods, respectively sleeved on the corresponding support rod sleeves; a plurality of locking hooks, respectively installed in the arc tracks in the corresponding grooves, used to lock the support rod sleeves; a rotating clip, used to release the locking of the support rod sleeves by the locking hooks; when the support rod sleeves need to be folded, the arc substrate needs to be translated until the locking hooks are completely separated from the support rod sleeves, and the arc substrate needs a large space for movement in the horizontal direction, which is inconvenient. Therefore, we provide a structure that can realize the rapid folding of the softbox by pushing the locking block, and can make the softbox unfold by directly pushing the support rods.
