Description

Technical Field

[0001] This invention relates to the field of e-commerce photography auxiliary equipment technology, specifically to a quick background changing device for e-commerce photography. Background Technology

[0002] Product photography is a crucial step in enhancing product visual appeal and driving marketing conversions. With the rapid development of the e-commerce industry, the demand for diverse photography backgrounds is increasing. Often, it's necessary to frequently change backdrops based on product type, seasonal promotions, or brand themes to create different scene atmospheres.

[0003] However, traditional e-commerce photography background changing devices mostly use basic mechanical structures, such as fixed brackets. The background cloth is usually fixed by manual hanging, clamping or pasting. When changing, the old cloth needs to be removed and the new cloth needs to be reinstalled. The whole process relies on manual operation, which is not only time-consuming and labor-intensive, but also easily leads to wrinkles, contamination or damage to the background cloth.

[0004] Therefore, a device for quickly changing backgrounds in e-commerce photography is proposed to solve the above problems. Summary of the Invention

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a quick-change device for e-commerce photography backgrounds, which has the advantages of quickly switching between background cloth and protective background cloth. It solves the problem that traditional e-commerce photography background changing devices mostly use basic mechanical structures, such as fixed brackets, and the background cloth is usually fixed by manual hanging, clamping or pasting. When changing, the old cloth needs to be removed and the new cloth needs to be reinstalled. The whole process relies on manual operation, which is not only time-consuming and labor-intensive, but also easily leads to wrinkles, contamination or damage to the background cloth.

[0006] (II) Technical Solution The technical solution of this invention to solve the above-mentioned technical problems is as follows: A quick-change device for e-commerce photography backgrounds includes a base and a background cloth. The top of the base is fixedly connected to an H-shaped support frame symmetrically distributed on both sides. A common rotating shaft is rotatably connected to opposite sides of the H-shaped support frame. A common support roller, located in front of the rotating shaft and adapted to the background cloth, is rotatably connected to opposite sides of the H-shaped support frame. A first meter-shaped support component is provided on the outer side of the left end of the rotating shaft, and a second meter-shaped support component adapted to the first meter-shaped support component is provided on the outer side of the right end of the rotating shaft. The first meter-shaped support component and the second meter-shaped support component... On opposite sides, there are identical take-up rollers arranged in a circular array. Each take-up roller is fixedly connected to a wound background cloth. The end of the background cloth away from the take-up roller is fixedly connected to a crossbar. The crossbar is adapted to both the first meter-shaped support assembly and the second meter-shaped support assembly. The top of the base is fixedly connected to a rectangular shell located on the opposite side of the H-shaped stand. Inside the rectangular shell, there are limiting components that are symmetrically distributed from left to right and extend upwards. The limiting components are adapted to the crossbars. The front side of the rectangular shell is slidably connected to an unlocking button that extends into the shell and abuts against the opposite side of the limiting components.

[0007] The beneficial effects of this invention are: This e-commerce photography background quick-change device uses multiple pre-loaded background cloths via a circular array of winding rollers. Combined with the cooperation of the rotating shaft and support rollers, users only need to pull the background cloth across the support rollers using a crossbar, and then engage the crossbar with the opposite side of the limiting component to complete the background cloth arrangement. Pressing the unlock button releases the locking limit and allows for background cloth replacement, significantly improving replacement efficiency. The first-meter-shaped support component is always in a taut state, preventing wrinkles in the background cloth when it is unfolded or rolled up, thus providing the advantages of quick background cloth switching and background cloth protection.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the first meter-shaped support assembly includes a first meter-shaped bracket, a first tube clamp, a columnar shell, and a coil spring. The first meter-shaped bracket is fixedly connected to the outer side of the left end of the rotating shaft. A take-up roller extending to its right side and arranged in a circular array is rotatably connected to the left side of the first meter-shaped bracket. A first tube clamp arranged in a circular array and adapted to the crossbar is fixedly connected to the periphery of the first meter-shaped bracket. A columnar shell arranged in a circular array and located outside the take-up roller is fixedly connected to the left side of the first meter-shaped bracket. A coil spring wound to the outside of the take-up roller is provided between the inner sidewall of the columnar shell and the outer side of the take-up roller. Furthermore, the second meter-shaped support assembly includes a second meter-shaped bracket and a second pipe clamp. The outer side of the right end of the rotating shaft is rotatably connected to a second meter-shaped bracket that is adapted to the first meter-shaped bracket. The second meter-shaped bracket is rotatably connected to the right end of the take-up roller. The periphery of the second meter-shaped bracket is fixedly connected to second pipe clamps that are arranged in a ring array and are adapted to both the first pipe clamp and the crossbar.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the user removes the crossbar of the background cloth to be used from the inside of the corresponding first and second tube clamps, so that the background cloth is unfolded from the take-up roller and passes over the support roller. During this process, the background cloth drives the take-up roller to rotate, which further tensions the coil spring. The coil spring is always in a taut state. After the background cloth is unfolded and fixed, it is tensioned by the coil spring, or after the background cloth is rolled up, the background cloth is tensioned and wrapped around the outside of the take-up roller. At the same time, the crossbar is inserted into the inside of the corresponding first and second tube clamps, which can prevent the background cloth from wrinkling and protect the background cloth.

[0011] Furthermore, the limiting assembly includes a wedge rod, a spring, a movable block, a guide groove, and a limiting groove. The rectangular shell has wedge rods symmetrically distributed on the left and right sides. The outer sides of each wedge rod are fitted with springs located inside the rectangular shell. The opposite sides of each wedge rod are fixedly connected to a movable block that is slidably connected to the rectangular shell and extends to the top of the rectangular shell. The opposite side of each movable block is provided with a guide groove adapted to the crossbar. The guide groove is provided with a limiting groove adapted to the crossbar. Furthermore, the left and right sides of the rear end of the unlock button are provided with chamfers, and the opposite side of the wedge rod abuts against the chamfers of the rear end of the unlock button.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the crossbar pulls the background fabric unrolled from the take-up roller and across the support roller, then places the crossbar into the limiting groove and presses it downward. The crossbar then slides downward along the limiting groove. During this process, the crossbar drives the movable block to move to the opposite side through the limiting groove, while the wedge rod further compresses the spring until the crossbar is aligned with the limiting groove. At this time, the spring returns to its original deformation, pushing the wedge rod and the movable block to move to the opposite side, locking the crossbar into the limiting groove and limiting its position. The background fabric... The background cloth is tensioned by the coil spring to complete the arrangement. Pressing the unlock button causes the chamfer at the rear of the unlock button to force the wedge rod and the movable block to move to opposite sides, while further compressing the spring so that the wedge rod and the movable block can return to their original positions after the unlock button is released. The movable block moves to opposite sides to separate the limiting groove from both ends of the horizontal bar, thus releasing the locking limit on the horizontal bar. After the horizontal bar is removed, the coil spring drives the winding roller to wind up the background cloth. Finally, the horizontal bar is inserted into the corresponding first and second tube clamps to complete the winding of the background cloth. Attached Figure Description

[0017] Working principle: Step 1: The user removes the crossbar 9 of the background cloth 2 to be used from the inside of the corresponding first tube clamp 602 and second tube clamp 702, so that the background cloth 2 is unrolled from the take-up roller 8 and passes over the support roller 5. Then, the crossbar 9 is placed into the limiting groove 115 and pressed down. The crossbar 9 slides down along the limiting groove 115. During this process, the crossbar 9 drives the movable block 113 to move to the opposite side through the limiting groove 115. At the same time, the spring 112 is further compressed by the wedge rod 111 until the crossbar 9 is aligned with the limiting groove 115. At this time, the spring 112 restores its deformation and pushes the wedge rod 111 and the movable block 113 to move to the opposite side, locking the crossbar 9 into the limiting groove 115 and limiting the crossbar 9. The background cloth 2 is also tensioned by the coil spring 604, completing the arrangement of the background cloth 2. Step 2: Press the unlock button 12. The chamfer at the rear end of the unlock button 12 forces the wedge rod 111 and the movable block 113 to move to opposite sides. At the same time, the spring 112 is further compressed so that the wedge rod 111 and the movable block 113 can be reset after the unlock button 12 is released. The movable block 113 moves to opposite sides to separate the limiting groove 115 from both ends of the horizontal bar 9, thereby releasing the locking limit of the horizontal bar 9. After the horizontal bar 9 is removed, the coil spring 604 drives the winding roller 8 to wind up the background cloth 2. Finally, the horizontal bar 9 is inserted into the corresponding first tube clamp 602 and second tube clamp 702 to complete the winding of the background cloth 2. Step 3: The coil spring 604 is always in a taut state. After the background cloth 2 is unfolded and fixed, it is taut by the coil spring 604, or after the background cloth 2 is rolled up, the background cloth 2 is taut and wrapped around the outside of the take-up roller 8. At the same time, the crossbar 9 is inserted into the corresponding first tube clamp 602 and second tube clamp 702, which can prevent the background cloth 2 from wrinkling and protect the background cloth 2.
