Description

Technical Field

[0001] The utility model relates to the technical field of photography auxiliary equipment, in particular to a portable background replacement device for product photography. Background Art

[0002] With the rapid growth of e-commerce and social media platforms, product photography has become an indispensable part of product promotion. Well-crafted product images not only attract consumers' attention but also enhance brand image. In professional product photography, the choice and variation of backgrounds are crucial for creating diverse visual effects.

[0003] Currently, most background replacement devices used for product photography adopt a foldable design, with the background cloth or paper fixed by a support frame. However, this type of device still has some obvious structural problems, which limit its wide application and convenience. First, the design of most support frames is relatively simple, relying on only a few fixed fulcrums to maintain stability, which can easily cause the device to fall over when encountering wind or minor collisions. Especially in outdoor shooting environments, insufficient stability becomes a major obstacle to use. Secondly, existing devices often take a lot of time to install and remove the background cloth or paper because they usually rely on fixing methods such as clips or Velcro. Although this fixing method is effective, it is not efficient enough when the background is frequently changed, which increases the time cost of shooting preparation. Finally, due to the lack of an effective storage mechanism, these devices are still large in size when not in use and are not easy to carry. This is particularly inconvenient for users who need to frequently move shooting locations. Utility Model Content

The main background frame 2 of this structure can be quickly retracted and released by The quick interface 5 is engaged with the outside of the protruding column 4 so that it can be quickly installed on the support column 1 for use. When it is necessary to select a suitable background cloth to use, it is only necessary to gently pull the auxiliary background frame 3 to extend it outward from the receiving slot of the main background frame 2. At this time, the new background cloth on the auxiliary background frame 3 will be displayed for the photographer to choose to use. This makes use of the staggered arrangement of the main background frame 2 and the auxiliary background frame 3, making background replacement more convenient. There is no need to repeatedly install and remove the background cloth like traditional devices, saving a lot of time and energy. In addition, a quickly retractable auxiliary support mechanism is hidden inside the rectangular seat 8, which can be activated at any time as needed to enhance the supporting capacity of the support column 1 and increase the stability of the device. When not in use, the auxiliary support mechanism inside the rectangular seat 8 can be The auxiliary background frame 3 is convenient to use and can be stored in a convenient manner. The auxiliary background frame 3 has a large storage area and a large storage area, which can be used as a storage medium for the main background frame 2.

The auxiliary background frame 3 has a large storage area and can be stored in a convenient manner. The auxiliary background frame 3 has a large storage area and can be stored in a convenient manner. The quick replacement of background cloth reduces the preparation time for shooting and improves work efficiency. Several elastic clips 9 are welded and fixed in the middle of the back side of the main background frame 2, and the elastic clips 9 are arc-shaped structures made of elastic metal. When the main background frame 2 of this structure is installed on the support column 1, the elastic clips 9 will automatically snap into the surface of the support column 1, forming a double fixation, ensuring that the main background frame 2 will not loosen or fall off during the shooting process. Both sides of the main background frame 2 are provided with through-holes that match the structure of the auxiliary background frame 3, and rubber friction strips 10 are provided on the inner walls on both sides of the through-holes of the main background frame 2, and a handle is welded and fixed in the middle of the outer end of the auxiliary background frame 3. The auxiliary background frame 3 of this structure can be easily inserted into or pulled out of the main background frame 2 through the through-holes on the main background frame 2.The rubber friction strip 10 can increase the friction between the auxiliary background frame 3 and the main background frame 2, ensuring that the auxiliary background frame 3 remains stable and not easy to slide during use, and the handle at the outer end of the auxiliary background frame 3 is convenient for the operator to pull and adjust, thereby improving the convenience and efficiency of use. The auxiliary support mechanism inside the rectangular seat 8 includes an upper support plate 81, a recess 82 and a lower support plate 83. The upper support plate 81 is movably arranged inside the rectangular seat 8, and the bottom end of the upper support plate 81 is movably connected to the bottom inner wall of the rectangular seat 8 through a pin shaft. The recess 82 is opened on the outside of the upper support plate 81, and the lower support plate 83 is movably arranged inside the recess 82. In this structure, the upper support plate 81 can be moved from the inside of the rectangular seat 8. The upper support plate 81 and the lower support plate 83 are turned out from the notch 82 of the upper support plate 81. The upper support plate 81 and the lower support plate 83 cooperate with each other to form a right-angle structure, thereby providing additional support for the bottom end of the support column 1 and enhancing the stability of the entire device. The outer side of the inner end of the lower support plate 83 is provided with a screw ring 85, and the interior of the screw ring 85 is interspersed with a screw pin 86 through a threaded structure, and the top of the upper support plate 81 is provided with a screw interface 87 that matches the screw pin 86 structure. When the upper support plate 81 and the lower support plate 83 are turned to the desired position to form a cross support structure, the screw pin 86 is rotated to pass through the screw ring 85 and enter the screw pin 86 at the top of the upper support plate 81. The interface 87 realizes the locking of the connection between the upper support plate 81 and the lower support plate 83, ensuring the stability and reliability of the two support plates in the supporting state. The inner side of the lower support plate 83 is bonded and fixed with a magnetic strip 84, and the top inner wall of the recess 82 is provided with an adsorption port that matches the structure of the magnetic strip 84. With this structure, when the lower support plate 83 is received in the recess 82, the magnetic strip 84 will be tightly combined with the adsorption port on the top inner wall of the recess 82, and the magnetic force is used to ensure that the lower support plate 83 is firmly fixed in the recess 82, preventing it from loosening or accidentally popping out when not in use. A clamping column 88 is welded and fixed on the inner wall of the upper end of the rectangular seat 8, and the clamping column 88 is fixed to the screw interface 87. The structure is consistent with that of the upper support plate 81. In this structure, when the upper support plate 81 needs to be stored inside the rectangular seat 8, the upper support plate 81 can be locked by aligning the screw interface 87 with the clamping column 88, so that the two are firmly stored together. The outer end of the lower support plate 83 is a bent structure, and a rubber anti-skid pad is bonded and fixed to the bottom wall of the outer end of the lower support plate 83.

Then, according to the needs, select the appropriate background cloth. By pulling the handle at the outer end of the auxiliary background frame 3, the auxiliary background frame 3 cooperates with the guide rail 7 and the guide rail seat 6 to make the auxiliary background frame 3 smoothly extend outward from the receiving slot of the main background frame 2. You can switch the background cloth you need to use at will. When you need to increase the stability of the support column 1, you can expand the auxiliary support mechanism inside the rectangular seat 8. The specific operation is to first flip the upper support plate 81 out of the rectangular seat 8, then flip the lower support plate 83 out of the recess 82 of the upper support plate 81, and finally rotate the screw pin 86 to pass through the screw ring 85 of the lower support plate 83 and enter the screw interface 87 at the top of the upper support plate 81, so as to lock the upper support plate 81 and the lower support plate 83. When not in use, the lower support plate 83 can be stored in the recess 82 of the upper support plate 81, and the magnetic strip 84 is tightly combined with the adsorption port on the top inner wall of the recess 82. At the same time, the upper support plate 81 is stored in the interior of the rectangular seat 8, and the screw interface 87 of the upper support plate 81 is engaged with the clamping column 88 on the inner wall of the upper end of the rectangular seat 8, so as to realize the rapid storage of the auxiliary support mechanism, thereby completing a series of work.
