Soft light cloth automatic opening and closing device for rectangular soft light box

Abstract

The invention provides a soft light cloth automatic opening and closing device for a rectangular soft light box, and relates to the field of photographic equipment. The soft light cloth automatic opening and closing device for the rectangular soft light box comprises a bearing plate, wherein a connecting block is fixedly connected to the outer surface of the bearing plate, a supporting rod is rotationally connected into the connecting block, a sliding rod is inserted into the end, away from the connecting block, of the supporting rod, a pull block sleeves the outer surface of the sliding rod, a tension spring sleeves the position, located at the front end of the pull block, of the outer surface of the sliding rod, the end, away from the sliding rod, of the pull block is rotationally connected with a fixing ring, the end, away from the pull block, of the fixing ring is connected with soft light cloth, the end, close to the bearing plate, of the soft light cloth is fixedly connected with an elastic rope, and the end, away from the soft light cloth, of the elastic rope is provided with a winding box. When the soft light cloth automatic opening and closing device for the rectangular soft light box is used, a retracting and releasing device works to retract a pull rope, the pull rope drives the pull block to move on the sliding rod, the pull block drives the soft light cloth to adjust the distance under the action of the tension spring, a light source is inserted from a fixing cylinder to complete assembling, and the soft light cloth automatic opening and closing device has the advantage that the distance between the soft light cloth and the light source is convenient to adjust.

Description

technical field [0001] The invention relates to the technical field of photographic equipment, in particular to an automatic opening and closing device for a soft cloth for a rectangular soft box.

AI Technical Summary

Problems solved by technology

[0003] The reflective area of ​​the existing rectangular softboxes is required to be larger and larger, but for the softboxes that are too large, the length of the umbrella ribs is too long, and it is difficult to store and open the umbrella ribs, and the operation is inconvenient. It takes a long time to install and extend the waiting time for photography. Although the existing device can use a motor to drive the soft box to open, it cannot adjust the distance between the soft cloth and the light source, resulting in the need to use the soft cloth twice to achieve the photographic effect.
