Technical Field

[0001] This utility model relates to the field of traditional cultural performance equipment technology, and in particular to a novel foldable shadow puppet support. Background Technology

[0002] Shadow puppetry, a traditional Chinese folk art performance, boasts a long history and profound cultural heritage. In shadow puppetry performances, the support frame, as a crucial component supporting the puppets and the screen, directly impacts the performance's effect through its structure and stability. However, traditional shadow puppetry frames are mostly fixed structures and bulky, making them extremely inconvenient to move for outdoor or touring performances, requiring significant manpower and resources, and occupying considerable storage space. When performance venue space is limited, fixed frames are difficult to adapt flexibly to different venue layouts, and the installation and dismantling processes are cumbersome, severely affecting the efficiency and mobility of shadow puppetry performance preparation. Summary of the Invention

[0003] The technical problem to be solved by this utility model is that the fixed structure bracket is difficult to adapt flexibly to different site layouts, and the installation, disassembly and transportation process is relatively cumbersome.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a novel foldable shadow puppet support, which has a rectangular frame structure, including uprights on both sides and a crossbar hinged to the end of the uprights. The crossbar has a hinge in the middle that allows it to be folded in half. The uprights are axially rotatably provided with connecting cylinders. A locking structure is provided between the connecting cylinders of the uprights on both sides. When the locking structure is in the locked state, the folded crossbar is located inside the locking structure and is limited by the locking structure. Fixed blocks that limit the rotation of the crossbar are slidably provided at both ends of the uprights.

[0005] Preferably, the locking structure includes a first connecting plate and a second connecting plate respectively fixed on the connecting cylinders on both sides. The movable ends of the first connecting plate and the second connecting plate are respectively provided with corresponding connecting holes and threaded holes. After folding the crossbar and making the connecting holes and threaded holes coaxial, the first connecting plate and the second connecting plate are connected by bolts to make the locking structure in a locked state.

[0006] Preferably, the first connecting plates are arranged in pairs on both sides of the connecting cylinder, and the second connecting plates are arranged in pairs on both sides of the other side of the connecting cylinder. When the first connecting plate and the second connecting plate are mated, the second connecting plate is located inside the two first connecting plates, and the second connecting plate is in contact with the inner sidewall of the first connecting plate.

[0007] Preferably, the fixing block is U-shaped, and a locking frame block is provided at the bottom of the fixing block. The locking frame block is connected to the rotating end of the crossbar by bolts.

[0008] Preferably, a connecting buckle is fixedly connected to the end of the connecting cylinder, and a storage block is provided on the top of the fixing block. The storage block is located on one side of the locking frame block, and the storage block can be connected to the connecting buckle by bolts.

[0009] Preferably, the outer walls of the uprights and crossbars are provided with annular grooves, and the edges of the curtain are connected with straps made of Velcro, with the straps corresponding to the annular grooves.

[0010] Preferably, the crossbar includes two telescopic rods with hinged movable ends, and the tail ends of the telescopic rods are connected to the end of the upright rod via hinges.

[0011] This utility model provides a novel foldable shadow puppet stand, which has the following beneficial effects.

[0012] The system employs a hinged crossbar and a vertical pole with rotatable connecting cylinders. The crossbar has a hinge in the middle for folding, and a locking structure between the connecting cylinders limits the folded crossbar's position. Sliding fixing blocks at both ends of the vertical pole further restrict the crossbar's rotation, effectively solving the problem of fixed structural supports. Its flexible folding design makes it easy to transport for outdoor or touring performances, significantly reducing manpower and material costs, and minimizing storage space when folded. When performance space is limited, the support can be flexibly adjusted according to the venue layout. Installation and disassembly are simple and convenient, greatly improving the efficiency of shadow puppet performance preparation and enhancing the performance's mobility. The locking structure is securely connected via first and second connecting plates and bolts. The C-shaped fixing blocks connect to the rotating end of the crossbar via locking frame blocks, further ensuring structural stability. The connecting buckles at the ends of the connecting cylinders and the storage blocks on top of the fixing blocks can be bolted together for easy storage. Annular grooves on the outer walls of the vertical and crossbars, combined with Velcro straps along the curtain edges, make curtain installation easier. The crossbars consist of hinged telescopic rods, which increases the flexibility and adjustability of the support structure. Attached Figure Description

[0021] like Figure 1-6 As shown, this utility model provides a novel foldable shadow puppet support, which has a rectangular frame structure, including uprights 1 on both sides and a crossbar 3 hinged to the end of the uprights 1. The crossbar 3 has a hinge in the middle that allows it to be folded in half. The uprights 1 are axially rotatably connected to a connecting tube 2. A locking structure is provided between the connecting tubes 2 on both sides of the uprights 1. When the locking structure is in the locked state, the folded crossbar 3 is located inside the locking structure and is limited by the locking structure. Fixing blocks 4 that limit the rotation of the crossbar 3 are slidably provided at both ends of the uprights 1.

[0022] By sliding the fixing block 4 to the end of the upright 1 and connecting the fixing block 4 and the crossbar 3 with bolts, the rotation limit of the crossbar 3 is achieved. After completing the rotation limit of all the crossbars 3, the bracket is installed. Then, the screen 10 is connected to the frame and the screen 10 is tied to the frame with the straps 11 to perform the shadow puppet show.

[0023] The main body of upright pole 1 and horizontal pole 3 is made of stainless steel, ensuring structural strength while providing excellent corrosion resistance and adapting to various performance environments. Fixing block 4 is made of ABS material with embedded stainless steel, ensuring sufficient strength while reducing the overall weight of the support frame. The end hinges are made of stainless steel and secured using stainless steel welding.

[0024] The support frame features a double-layer structure, ensuring stable placement on the ground. It comprises four uprights 1, with the front and rear uprights 1 connected by connecting rods 9 to guarantee stability. The welded joints are ground smooth to ensure a burr-free surface, enhancing both aesthetics and safety while preventing burrs from scratching the curtain 10.

[0025] like Figure 1 and Figure 5 As shown. The locking structure includes a first connecting plate 5 and a second connecting plate 6 respectively fixed on the connecting cylinders 2 on both sides. The movable ends of the first connecting plate 5 and the second connecting plate 6 are respectively provided with corresponding connecting holes and threaded holes. After folding the crossbar 3 so that the connecting holes and threaded holes are coaxial, the first connecting plate 5 and the second connecting plate 6 are connected by bolts to make the locking structure in a locked state.

[0026] When storing the shadow puppet frame, the fixing block 4 is moved to the middle of the upright 1 so that the crossbar 3 can be folded in half. Then, the first connecting plate 5 and the second connecting plate 6 are brought close together and the connecting hole is aligned with the threaded hole. The first connecting plate 5 and the second connecting plate 6 are locked with bolts to realize the storage of the shadow puppet frame.

[0027] When performing shadow puppetry, the first connecting plate 5 and the second connecting plate 6 are rotated to the outside of the screen 10 to avoid obstructing shadows.

[0028] like Figure 5 As shown. The first connecting plates 5 are arranged in pairs on both sides of the connecting cylinder 2, and the second connecting plates 6 are arranged in pairs on both sides of the connecting cylinder 2 on the other side. When the first connecting plates 5 and the second connecting plates 6 are connected, the second connecting plates 6 are located inside the two first connecting plates 5, and the second connecting plates 6 are in contact with the inner sidewall of the first connecting plates 5. When storing the shadow puppet frame, the first connecting plates 5 and the second connecting plates 6 are connected. When connected, the middle part of the two folded crossbars 3 is located inside the first connecting plates 5. Then, the first connecting plates 5 and the second connecting plates 6 are fixedly connected by bolts at the top and bottom. At this time, the hinge in the middle of the crossbar 3 is located between the two bolts, which not only completes the storage of the shadow puppet frame, but also limits the position of the crossbars 3.

[0029] like Figure 5 and Figure 6 As shown. The fixing block 4 is U-shaped, and a locking frame block 12 is provided at the bottom of the fixing block 4. The locking frame block 12 is connected to the rotating end of the crossbar 3 by bolts. By sliding the fixing block 4 to the bottom end of the upright 1, the locking frame block 12 at the bottom of the fixing block 4 is in contact with the top surface of the crossbar 3. Then, the locking frame block 12 and the crossbar 3 are connected by bolts to achieve angular limitation of the crossbar 3.

[0030] like Figure 5 As shown. A connecting buckle 7 is fixedly connected to the end of the connecting cylinder 2. A storage block 13 is provided on the top of the fixing block 4, located on one side of the locking frame block 12. The storage block 13 can be connected to the connecting buckle 7 via bolts. When storing the shadow puppet bracket, the fixing block 4 and the crossbar 3 are separated, and the fixing block 4 is moved to fit against the connecting buckle 7. The storage block 13 and the connecting buckle 7 are then connected by bolts, thus storing the fixing block 4. Furthermore, since the storage block 13 is located on one side of the locking frame block 12, there will be no interference when installing or removing the bolts.

[0031] like Figure 4As shown, to facilitate the installation of the screen 10, annular grooves are provided on the outer walls of both the uprights 1 and the crossbars 3. A strap 11 made of Velcro is connected to the edge of the screen 10, with the strap 11 corresponding to the annular groove. The annular groove is positioned at the corresponding location, and the strap 11 is directly tied into the annular groove to secure the screen 10, ensuring its stability.

[0032] like Figure 1-5 As shown. The crossbar 3 includes two telescopic rods 8 with hinged movable ends. The tail end of the telescopic rod 8 is connected to the end of the upright 1 via a hinge. By adjusting the connection method between different locking holes in the head member and the mounting hole in the tail member of the telescopic rod 8, the length of the telescopic rod 8 can be adjusted, thereby adjusting the length of the crossbar 3. Depending on the performance needs, different widths of curtains 10 can be used. By adjusting the length of the crossbar 3, the on-site usage requirements can be met, and the shortened crossbar 3 is easier to store.
