[0001] The utility model relates to the technical field of the support of a shadow play stage, and particularly relates to a support member for a shadow play stage. Background Art

[0002] The shadow play performance stage projects the images of shadow puppets onto a curtain through light. For a traditional shadow play performance stage, its construction structure is relatively simple: a large white cotton cloth is used as the screen for the light box, an oil lamp is used as the light source, and two square tables are placed on the stage frame to place props; the main body of the stage frame is built with several bamboo poles of different diameters, and then the top, left and right, and back of the stage are covered with reed mats, and the stage frame is fixed with thick hemp ropes, and thin hemp ropes are pulled between the standing bamboo poles to firmly fix the stage frame; two long poles in front of the stage frame are erected, the curtain is perpendicular to the line of sight of the audience, and is supported by the curtain support members in front of the stage frame. The curtain support members are composed of two upper and lower cross bars and two left and right vertical bars on the frame facing the audience. The cross bars are fixedly connected between the upper parts of the vertical bars, and the bottoms of the vertical bars are directly placed on the ground; the rope buckles for tying the stage frame use a buckle type called "pig brake hoof", first making two loops with the rope, and then overlapping the two loops; the light source uses an oil lamp or an electric lamp. The built shadow play performance stage is an inverted U-shaped structure surrounded by three sides in appearance.

[0003] Although the main structure of the above-mentioned shadow play stage has a low cost, it requires a large number of poles and is heavy; in order to support the curtain, the overall curtain support structure built has a large floor area, and a large number of bamboo poles are used in the construction, which is time-consuming both in installation and disassembly, and requires the assistance of multiple people for construction, which is extremely inconvenient.

The pull plates 26 on each clamping assembly are pulled in sequence, and then the edge of the curtain is placed between the rear inner wall of the U-shaped plate 23 and the extrusion block 24. Under the elastic force of the second spring 27, the extrusion block 24 squeezes the edge of the curtain, thereby realizing the clamping of the curtain;

[0042] When disassembling and folding, the first locking knob 34 is loosened so that the tail end of the first locking knob 34 disengages from the positioning hole 11 on the cross plate 10, thereby unlocking the support leg assembly 30, the curtain clamping mechanism 20, and the cross plate 10. Thus, the support leg assembly 30 and the curtain clamping mechanism 20 can be rotated. The push block 17 is pulled to drive the clamping plate 15 to disengage from the card slot 12 on the cross plate 10, and the locking between the two cross plates 10 can be released, thus facilitating the folding of the support member of the shadow play stage;

[0043] The support member of the shadow play stage is provided with a cross plate 10, a curtain clamping mechanism 20, and a support leg assembly 30, which can effectively clamp and support the curtain. Moreover, the unfolding and storage operations of the support member of the shadow play stage are very simple and fast, and can be operated by one person, with flexible use.

[0044] As Figure 1 shown, the tail end of the second locking knob 35 extends into the outer sleeve 31, and the tail end of the second locking knob 35 abuts against the outer wall of the support plate 32.

[0045] In the present utility model, by rotating the second locking knob 35, the tail end of the second locking knob 35 is moved away from the support plate 32, the locking of the support plate 32 can be released, so that the support plate 32 can slide within the outer sleeve 31, thereby the overall length of the support leg assembly 30 can be adjusted, and thus the height of the curtain can be adjusted. By tightening the second locking knob 35, the tail end of the second locking knob 35 tightly abuts against the surface of the support plate 32, the support plate 32 can be locked.

[0046] Only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways.
