The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 5, the present application provides a foldable reflector 100 for a photography lamp, which comprises a chuck 10, a plurality of support rods 20 radially distributed around the chuck 10, and a reflective fabric 40 lining the support rods 20, wherein one end of each support rod 20 is hinged to the chuck 10, and has an expanded state and a folded state for supporting the reflective fabric 40 to form a cover structure.

The chuck 10 is installed at the lamp head of the photographic lamp, a through hole 14 corresponding to the lamp head is formed in the center of the chuck 10, and the size of the through hole 14 is set according to the specific requirements of the lamp head. The supporting rods 20 can be unfolded and folded to correspondingly drive the reflective fabric 40 to be unfolded and folded, and the number of the supporting rods 20 is selected according to actual requirements, so that the reflective device 100 has different shapes (such as four corners, an octagonal shape, and the like).

The supporting rod 20 may be internally or externally penetrated relative to the reflective fabric 40, the internal penetration means that the supporting rod 20 is located at the inner side of the cover body structure, and the external penetration means that the supporting rod 20 is located at the outer side of the cover body structure, and generally, the supporting rod 20 penetrates into a collar radially arranged on the reflective fabric 40 to realize fixation.

The reflector 100 may be a soft light box or a radome, and a soft light cloth is generally disposed at an opening of the soft light box and is usually connected to an inner sidewall of the soft light box by a hook and loop fastener.

In order to maintain the support rod 20 in the unfolded state, a locking mechanism 30 is provided between the support rod 20 and the chuck 10. Specifically, the locking mechanism 30 includes a swinging member 31 and a holding member (not shown), the swinging member 31 is hinged at a middle portion thereof to the chuck 10 and divided into an operating portion 311 and an engaging portion 312 with the hinged portion as a boundary, and the engaging portion 312 of the swinging member 31 has two states of locking and releasing the support rod 20; the holding member serves to restrict the swinging member 31 to the locked state.

When the swinging member 31 is in the locked state, the holding member restricts the swinging member 31 to the locked state, at which time the light reflecting device 100 is in the unfolded state; the swinging member 31 overcomes the resistance of the holding member and is in a release state, and all the support rods 20 are folded by rotating the support rods 20 so that the light reflecting device 100 is in a folding state. When the supporting rod 20 is changed from the unfolded state to the folded state, the operating portion 311 of the swinging member 31 is controlled to drive the engaging portion 312 to move until the engaging portion 312 is switched to the released state, and at this time, the supporting rod 20 can be folded, that is, the supporting rod 20 can rotate around the chuck 10 to change the relative position with the chuck 10.

In this application, locking mechanism 30's simple structure can reduce the assembly degree of difficulty of each part to prolong locking mechanism 30's life, and it is more convenient to operate.

In some embodiments, the retaining member is a torsion spring that is threaded around the pivot of the oscillating member 31 and acts between the oscillating member 31 and the chuck 10. Of course, in other embodiments, the retaining member may be a compression spring or other returning member as long as the retaining member can drive the engaging portion 312 of the swinging member 31 and the supporting rod 20 to be in the locking state.

In some embodiments, as shown in fig. 1 and 5, the support rod 20 has a hinged end 21 and a free end 22, and the edge of the chuck 10 is provided with a mounting groove 15 which is matched with the hinged end 21 of the support rod 20 to prevent the hinged end 21 of the support rod 20 from being exposed, and to allow the support rod 20 to be rotated only in a single direction, so that the mounting groove 15 is opened at one side.

Referring to fig. 5 and 6, the support rod 20 includes a connecting seat 23 hinged to the chuck 10 and a rod 24, one end of the rod 24 is inserted into the connecting seat 23, and the other end extends away from the chuck 10.
