They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0021] In view of the current existing technology, by setting up a storage box and a tape measure spring, the background cloth can be rolled up into the storage box for storage, so that the device can conveniently store the background cloth without folding the background cloth, so there will be no wrinkles, which greatly facilitates the use of the operator. By setting up a fixed bottom box, the device can store the folding column, the fixed cross bar and the telescopic bracket, making the device very convenient to store. By setting up the mounting holes, the folding column and the fixed cross bar, the fixation of the device can be strengthened when it is unfolded. By setting up the hanging ring block, the device can be conveniently hung on the wall for use. However, in actual use, its scope of application is limited, and it does not have a good supporting effect, which brings inconvenience to use.

[0022] like Figure 1-7 As shown, the embodiment of the present invention provides a photography background cloth winding mechanism, comprising: a telescopic rod 10, the top of which is rotatably connected to a fixing seat 11; a connecting rod 12, inserted into the side of the fixing seat 11; a baffle 13, fixedly connected to the outside of the connecting rod 12; a motor 14, fixedly connected to another side of the fixing seat 11; a groove 15, opened on the fixing seat 11; a rod 16, rotatably connected to the groove 15, the output end of the telescopic rod 10 is fixedly connected to the outside of the groove 15; a cavity 20, opened in the fixing seat 11; a telescopic rod 21, fixedly connected to the output end of the motor 14, the other end of the telescopic rod 21 The end is inserted into the connecting rod 12; the ring body 1 22 is rotatably connected to the outside of the telescopic rod 21; the push rod 23 is fixedly connected to the side of the ring body 1 22, and the other end of the push rod 23 passes through the fixed seat 11; the pull ring 24 is fixedly connected to the outer end of the push rod 23; the spring 25 is sleeved on the outside of the push rod 23, and the pull ring 24 is connected to the fixed seat 11 through the spring 25; the slider 2 30 is slidably connected to the side of the fixed seat 11; the rod body 2 31 is rotatably connected to the side of the slider 2 30, and the other end of the rod body 2 31 is rotatably connected to the pull ring 24; the rod body 32 is fixedly connected to the telescopic rod 1 10.

[0023] When the photographic background cloth needs to be rolled up, the motor 14 is turned on to rotate its output end while driving the connecting rod 12 to rotate through the telescopic rod 21, thereby realizing automatic rolling up of the photographic background cloth. After the rolling up is completed, the fixing bolt on the telescopic rod 10 is loosened, and then the connecting rod 12 is pushed to lower the height of the connecting rod 12. The telescopic rod 10 is rotated to make the telescopic rod 10 drive the rod body 16 to rotate in the groove body 15. After the two telescopic rods 10 and the connecting rod 12 are in a horizontal state, the device is folded, thereby facilitating subsequent storage, transfer or storage. Repeat the above steps in reverse, so that the two telescopic rods 10 are in contact with the ground, the connecting rod 12 rises to the highest point, and the driving motor 14 reverses to unwind the photographic background cloth, thereby facilitating subsequent filming work; When the photographic background cloth needs to be replaced, the pull ring 24 is pulled outward, so that the pull ring 24 pulls the ring body 1 22 to slide outward through the push rod 23, and at the same time, the spring 25 is pulled to drive the telescopic rod 21 to contract, so that one end of the telescopic rod 21 slides out from the connecting rod 12. After the connection between the telescopic rod 21 and the connecting rod 12 is cancelled, the connecting rod 12 is pulled out from the other fixing seat 11, and the connecting rod 12 and the photographic background cloth thereon are disassembled, thereby facilitating replacement or classified storage. Or when changing the height of the telescopic rod 10, the fixing seat 11 is slid downward, and then the rod body 32 is brought into contact with the slider 2 30, and the slider 2 30 is pushed to slide upward. At the same time, the pull ring 24 is pushed to slide outward through the rod body 2 31, thereby facilitating the disassembly of the connecting rod 12 and the photographic background cloth.

[0024] Specifically, rod body 16 is a rotating shaft, which facilitates the telescopic rod 10 to drive rod body 16 to rotate in the groove body 15. Rod body 2 31 plays an auxiliary transmission role, causing slider 2 30 to slide upward. While sliding, the pull ring 24 is pushed outward by rod body 2 31, thereby facilitating the disassembly of the connecting rod 12 and the photographic background cloth.

[0025] Specifically, the output end of the motor 14 is fixedly connected to one end of the second telescopic rod 21, so that after the motor 14 is turned on, the second telescopic rod 21 directly rotates.

[0026] Specifically, both telescopic rods 10 are threadedly connected with fixing bolts for fixing the height of the telescopic rods 10 , which belongs to the prior art and will not be described in detail.

[0027] Furthermore, the telescopic rod 21 includes: a fixed rod 213, fixedly connected to the output end of the motor 14; a slider 212, fixedly connected to one end of the fixed rod 213; a fixed rod 211, slidably connected to the outside of the slider 212, one end of the fixed rod 211 is inserted into the connecting rod 12, and the ring body 22 is rotatably connected to the outside of the fixed rod 211 through a bearing.

[0028] When the motor 14 is working, its output end drives the fixed rod 213 to rotate, and then drives the fixed rod 1 211 and the connecting rod 12 to rotate through the slider 1 212. When the pull ring 24 slides outward, the ring body 1 22 drives the fixed rod 1 211 to slide on the slider 1 212, which does not affect the normal use of the telescopic rod 21 and facilitates the disassembly of the connecting rod 12.

[0029] Furthermore, a clamping mechanism 40 is provided on the outer side of the telescopic rod 10, and the clamping mechanism 40 is used to clamp the background cloth, so that the photographic background cloth can reduce wrinkles when in use and improve practicality.

[0030] Furthermore, the clamping mechanism 40 includes: a ring body 401 slidably connected to the outside of the telescopic rod 10; a fixed block 402 fixedly connected to the side of the ring body 401; a threaded rod 403 rotatably connected to the inside of the fixed block 402; a splint 404 provided on the fixed block 402, and one of the splints 404 is fixedly connected to the fixed block 402, and the other splint 404 is threadedly connected to the threaded rod 403 and slidably connected to the fixed block 402.

[0031] When clamping the photographic background cloth, one end of the bottom is placed between the two clamping plates 404, and then the threaded rod 403 is rotated to slide one clamping plate 404 toward the other clamping plate 404 through the threaded connection between the rod and the clamping plate 404, thereby clamping the photographic background cloth.

[0032] Furthermore, the threaded rod 2 50 is rotatably connected to the bottom end of the telescopic rod 10; the slider 3 51 is threadedly connected to the outside of the threaded rod 2 50; the adjusting rod 52 is fixedly connected to the outer ring 53 of the slider 3 51 and is rotatably connected to the outer end of the adjusting rod 52; the support rod 54 is rotatably connected to the bottom of the telescopic rod 10, and the ring 53 is slidably connected to the support rod 54.

[0033] Before using the photographic background cloth, rotate the threaded rod 2 50, and through its threaded connection with the slider 3 51, the slider 3 51 slides upward, and drives the adjusting rod 52 to slide upward, and then the adjusting rod 52 pushes the ring 53 to slide upward on the outside of the support rod 54, and pushes the support rod 54 to rotate, increasing the contact area with the ground, thereby improving the support stability.

[0034] Furthermore, a plurality of support rods 54 are provided so that the plurality of support rods 54 can contact the ground at the same time, thereby improving stability.

[0035] Furthermore, the bottom end of the ring body 2 401 is fixedly connected to a shell 60 , so that when the height of the clamping mechanism 40 is adjusted, the shell 60 is driven to slide downward, and then the shell 60 covers the threaded rod 2 50 , thereby covering and protecting the threaded rod 2 50 .

[0036] Furthermore, a sphere is fixedly connected to the bottom end of the support rod 54 so that the contact area between the support rod 54 and the ground remains unchanged, thereby ensuring stability.

[0037] Furthermore, the length of the support rod 54 is greater than the length of the second threaded rod 50, thereby preventing the second threaded rod 50 from contacting the ground.

[0038] Furthermore, a fixing bolt is threadedly connected to the fixing seat 11. By rotating the fixing bolt on the fixing seat 11, the fixing bolt is inserted into the telescopic rod 10, thereby locking the angle between the telescopic rod 10 and the fixing seat 11 to improve stability.

[0039] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
