Detailed Description

In order to make the present utility model better understood by those skilled in the art, the following description of the technical solutions of the present utility model will be made in detail, but not all embodiments of the present utility model are apparent to some embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

As shown in fig. 1 to 6, a soft light box chuck comprises a circular chuck body 1, wherein the chuck body 1 comprises a first disk body 11 and a second disk body 12, the first disk body 11 is used for movably connecting a first supporting rod 21, and the second disk body 12 is used for movably connecting a second supporting rod 22. The first support bar 21 and the second support bar 22 may have the same structure, and they are named separately for distinguishing the installation positions of the support bars, but may be different, and are not particularly limited. The first disc 11 and the second disc 12 are also integrally connected, in other words, the first disc 11 and the second disc 12 are two parts of the chuck body 1, and are named separately for distinguishing the specific structures of the first disc 11 and the second disc 12.

The second tray 12 is provided with at least a through groove 121, and the second support bar 22 has a folded state in which the second support bar 22 and the first support bar 21 are at least partially vertically opposed, i.e., the soft light box is flat. Here, the up-down opposite means that the first support bar 21 and the second support bar 22 are substantially oriented in one direction. When the second support bar 22 approaches the lower surface of the first tray 11 so as to move into the through groove 121, the above-described folded state can be entered.

More specifically, the second support bar 22 has an unfolded state, a folded state, and a folded state. In the unfolded state, as shown in fig. 2 and 9, the second support bar 22 is close to the same plane as the chuck body 1, so that the second support bar 22 spreads the soft cloth; in the folded state, the second support rod 22 is close to the vertical position of the chuck main body 1, so that the soft cloth is folded; in the folded state, as shown in fig. 8, the second support rod 22 is attached to or near to the lower surface of the chuck body 1, and the second support rod 22 faces the direction of the first support rod 21, so that the first support rod 21 and the second support rod 22 are opposite up and down, and the soft light box is flat, so that the problems that when the soft light box is folded in the existing structure, the chuck and the support piece of the soft light box are still in a relatively three-dimensional structural form, and the storage occupied space is large are solved.

The above-mentioned scheme does not specifically limit the structure of the first tray 11 and the first support bar 21, as long as the second support bar 22 can move to the through groove 121, so that the first support bar 21 and the second support bar 22 are opposite up and down. In the present embodiment, the first support lever 21 has an expanded state and a collapsed state, which swings in the circumferential direction of the first disk 11, thereby switching between the expanded state and the collapsed state. In other words, the first support rod 21 is in a state close to being in the same plane as the chuck body 1, regardless of the unfolded state or the folded state. When the first support bar 21 is in a folded state, it can be matched with the second support bar 22 in a folded state to realize the folding of the soft light box, as shown in fig. 8, and at this time, the first support bar 21 and the second support bar 22 are both close to a state in the same plane with the chuck main body 1.

The movable groove 125 penetrates through the lower surface of the chuck body 1, and is in an unfolded state when the second support bar 22 is hung on the hanging groove 124; when an external force is applied to disengage the second support bar 22 from the hanging slot 124, the second support bar 22 can enter the movable slot 125 to switch the second support bar 22 to the folded state, as shown in fig. 9

Taking the orientation of the use state of the soft light box shown in fig. 1 as an example, the through groove 121 is formed on the lower surface of the second disk body 12, and the through groove 121 penetrates the lower surface of the chuck body 1 and penetrates the inner ring 122 of the second disk body 12. The second support bar 22 can be rotated from the movable groove 125 to the through groove 121, thereby achieving switching of the second support bar 22 between the collapsed state and the folded state.

As shown in fig. 5, the through groove 121 and the movable groove 125 are fitted through the inner ring 122 and the outer ring 123 of the second disk body 12. The through groove 121 forms an included angle with the movable groove 125, the included angle can be an acute angle or an obtuse angle, and the through groove 121 is communicated with the movable groove 125; or the through groove 121 and the movable groove 125 are disposed in parallel, that is, the through groove 121 is coaxial with the movable groove 125, and the through groove 121 and the movable groove 125 communicate. In this embodiment, the included angle between the through groove 121 and the movable groove 125 gradually increases along the circumferential direction of the second disc 12, as shown in fig. 5, and the included angle between the through groove 121 and the movable groove 125 changes from an acute angle to an obtuse angle, wherein a group of through grooves 121 and movable grooves 125 are disposed in parallel.
