[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] As attached Figure 1 To be continued Figure 6 This utility model provides an easy-to-install curtain support frame, including a support bracket 1; two fixing buckles 2, which are symmetrically installed on the top of the support bracket 1, with slots 3 at the bottom of the fixing buckles 2 and symmetrical slots 4 on the front and rear sides of the fixing buckles 2; a crossbar 5, with a slit 6 in the middle of the crossbar 5, and symmetrical first tensioning members 7 on the front of the crossbar 5, through which the background curtain 15 can be fixed in the slit 6; symmetrical U-shaped pieces 8 are fixedly installed on the top of the crossbar 5, with symmetrical protrusions 9 integrally formed on the top of the U-shaped pieces 8, which can be inserted into the slots 3 and have the protrusions 9 engaged in the slots 4.

[0027] The specific installation process involves inserting the top of the background curtain 15 into the gap 6, and then tightening and fixing the background curtain 15 along the width direction using the two first tensioning pieces 7. Next, pick up the horizontal bar 5, gently pinch the U-shaped piece 8 and the protruding head 9 inward, align them, and snap them into the fixing buckle 2. This allows the background curtain 15 to be quickly and stably hung on the support bracket 1. Conversely, the background curtain 15 can be quickly disassembled and replaced.

[0028] Preferably, both the U-shaped piece 8 and the protrusion 9 are made of copper-based shape memory alloy, which has good elasticity and low cost.

[0029] Preferably, the first tensioning member 7 includes a lead screw 71, which is threaded onto the crossbar 5. One end of the lead screw 71 is rotatably connected to a pressure plate 72, and the other end is fixedly connected to a knob 73. The pressure plate 72 is slidably connected inside the crossbar 5. By rotating the knob 73, the lead screw 71 drives the pressure plate 72 to slide back and forth along a straight line inside the crossbar 5 through the thread, thereby allowing the pressure plate 72 to quickly clamp and fix the background curtain 15 inside the crossbar 5.

[0030] Preferably, the support bracket 1 includes a crossbeam 11, with uprights 12 bolted to both sides of the crossbeam 11 along its length, a reinforcing rod 13 bolted between the two uprights 12, and leg rods 14 bolted to the bottom of each of the two uprights 12. Two fixing buckles 2 are symmetrically bolted onto the support bracket 1. The above structures are connected to each other by bolts, allowing for disassembly and transport, thus improving the overall portability of the curtain support bracket.

[0031] Preferably, the crossbeam 11, upright 12, reinforcing bar 13, and leg bar 14 are all made of aluminum alloy.

[0032] Furthermore, each of the two leg rods 14 is provided with a second tensioning member 10. The second tensioning member 10 includes two telescopic rods 101. The top end of the telescopic rod 101 is fixedly connected to a pressure frame 102, and the bottom end is fixedly connected to the leg rod 14. A second lead screw 103 is threadedly installed in the middle of the pressure frame 102. The bottom end of the second lead screw 103 is rotatably connected to the leg rod 14. A handwheel 104 is fixedly connected to the top end of the second lead screw 103. A wheel frame 105 and a second pressure plate 107 are fixedly connected to both sides of the length direction of the pressure frame 102, respectively. A horizontally symmetrical limiting pressure wheel 106 is rotatably connected to the wheel frame 105.

[0033] Preferably, the wheel frame 105 has a U-shaped structure, the pressure plate 107 has an L-shaped structure, and the bottom surface of the pressure plate 107 is provided with an anti-slip rubber pad 108 to increase the friction of the pressure plate 107 and improve the stability of the pressure plate 107 in pressing and fixing the wheel frame 105.

[0034] Specifically, after the backdrop 15 is hung up, the bottom of the backdrop 15 is passed through the gap of the limiting pressure roller 106 and laid flat. Then, the screw 103 is rotated by the handwheel 104, and the transmission pressure frame 102 is lowered vertically. The bottom of the backdrop 15 is pressed and fixed to the ground by the limiting pressure roller 106 and the pressure plate 107, so that the backdrop 15 is laid at a right angle and can be kept taut. This not only prevents the photographer from slipping on the backdrop 15, but also avoids wrinkles on the surface of the backdrop 15, which would affect the shooting effect.
