[0002] Currently, in photography work, in order to comprehensively display the appearance and details of the object to be photographed, it is often necessary to rotate the photographing device around the object to be photographed for at least one week to photograph the circumferential direction of the object to be photographed and the nearby scenes.

[0003] In the prior art, a photography workbench for realizing rotary photography generally includes a base, a tooling plate for placing the object to be photographed is arranged on the base, a swing arm assembly that can rotate circumferentially around the tooling plate is rotatably arranged on the base, the end of the swing arm assembly is used to install the photographing device, the swing arm assembly includes a plurality of articulated arms, and the position adjustment of the photographing device is realized by adjusting the angle between the articulated arms.

[0004] Since the swing arm assembly needs to rotate at a high speed during photography, the angle between the articulated arms is likely to deviate, resulting in a change in the relative position of the photographing device, which affects the shooting effect. Moreover, when adjusting the position of the photographing device by using the swing arm assembly, the adjustment range is small, which is not conducive to multi-directional photography. In addition, the photography workbench with the above structure cannot be folded and stored, has a large volume, and is not convenient for storage and transportation. Summary of the Invention

[0032] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] See 1 and Figure 3 , a photographic workbench of the present invention includes: a bottom support frame 100, a storage tray 600 is provided on the bottom support frame 100, and the storage tray 600 is generally used to place the object to be photographed; a rotating frame 200, rotatably arranged around a vertical axis on the bottom support frame 100; a lifting assembly 300, provided on the rotating frame 200 and capable of lifting and moving relative to the rotating frame 200; a translation assembly 400, provided on the lifting assembly 300 and capable of moving radially relative to the lifting assembly 300 along the storage tray 600; a photographic pan-tilt head 500, provided on the translation assembly 400 and located above the storage tray 600; a frame support structure can be formed among the lifting assembly 300, the translation assembly 400, and the rotating frame 200.

[0034] The photographic workbench with the above structure uses the cooperation of the lifting assembly 300 and the translation assembly 400 to adjust the relative position between the photographic pan-tilt head 500 and the storage tray 600, so that the adjustment range of the photographic pan-tilt head 500 is relatively wide, and a frame support structure can be formed among the lifting assembly 300, the translation assembly 400, and the rotating frame 200. When the photographic pan-tilt head 500 rotates around the storage tray 600, the frame support structure helps to keep the photographic pan-tilt head 500 stable and avoid the shaking of the photographic equipment, which affects the stability during the rotating shooting.

[0035] See Figure 1 and Figure 3 , in some embodiments of the present invention, a first cross bar is provided on the rotating frame 200, the extending direction of the first cross bar is orthogonal to the rotation axis of the rotating frame 200, the lifting assembly 300 includes two vertical rods 310 respectively movably provided at both ends of the first cross bar, a lifting adjustment structure 320 is provided between the vertical rods 310 and the first cross bar, the translation assembly 400 includes a connecting rod 410 connected between the two vertical rods 310 and a sliding seat 420 slidably provided on the connecting rod 410, the connecting rod 410 is parallel to the first cross bar, and the photographic pan-tilt head 500 is provided on the sliding seat 420. The two vertical rods 310, the first cross bar, and the connecting rod 410 together form a quadrilateral frame support structure, which helps to keep the photographic pan-tilt head 500 stable during the rotating shooting. Of course, it can be understood that according to the needs of use, the number of the vertical rods 310 can also be increased as long as a stable frame support structure can be formed.

[0036] Among them, when it is necessary to adjust the height of the camera support 500, the vertical rod 310 is driven by the lifting and adjusting structure 320 to rise or fall a certain distance relative to the first cross bar and then fixed. When it is necessary to adjust the distance between the camera support 500 and the placing tray 600 in the horizontal direction, the sliding seat 420 is driven to slide a certain distance on the connecting rod 410 and then fixed. The above-mentioned camera workbench has a high position adjustment accuracy for the camera support 500 and a wide adjustment range.

[0037] See Figure 1 and Figure 2 In some embodiments of the present invention, in order to expand the working mode of the camera workbench of the present invention, the connecting rod 410 is detachably connected to the vertical rod 310. One end of the connecting rod 410 can be installed on the first cross bar and the other end of the connecting rod 410 extends away from the placing tray 600. The upper end of one vertical rod 310 can be connected to the sliding seat 420 to fix the sliding seat 420, and a projection screen 800 is installed on the other vertical rod 310. During shooting, the photographic equipment installed on the camera support 500 can shoot the side of the item on the placing tray 600 frontally, and the projection screen 800 can provide different shooting backgrounds for the user. In some embodiments, the projection screen 800 is detachably connected to the vertical rod 310, which helps to replace different projection screens 800 according to different shooting preferences.

[0038] See Figure 1 and Figure 3 In some embodiments of the present invention, the first cross bar includes two first pipe units 210 pivotally connected to the rotating frame 200. The two first pipe units 210 are centrosymmetric about the center of the rotating frame 200. The first pipe unit 210 includes a first pipe section 211 connected to the rotating frame 200 and a second pipe section 212 that can rotate about the axis of the first pipe section 211. The vertical rod 310 is connected to the second pipe section 212. When the camera workbench is in the Figure 1 shown state, the photographic equipment on the camera support 500 takes a top-down shot of the item on the placing tray 600. In order to be able to show the specific structure of the side of the item, the user can rotate the whole formed by the vertical rod 310, the connecting rod 410 and the second pipe section 212 about the axis of the first pipe section 211. Taking Figure 1 shown as an example, the photographic equipment can sequentially shoot the left side, the top and the right side of the item, realizing the expansion of the shooting range close to 180°.

[0039] See Figure 1 、 Figure 2 and Figure 3, in some embodiments of the present invention, in order to be able to reduce the volume of the photographic workbench of the present invention when stored, the connecting rod 410 is detachably connected to the vertical rod 310. The first cross bar includes two first pipe units 210 pivotally connected to the rotating frame 200. The two first pipe units 210 are centrosymmetric about the center of the rotating frame 200. The two vertical rods 310 are respectively movably connected to the two first pipe units 210, and the vertical rod 310 can be received in the lumen of the corresponding first pipe unit 210.

[0040] When it is necessary to store the photographic workbench, first detach the connecting rod 410 from the vertical rod 310, then drive the vertical rod 310 to move relative to the first pipe unit 210 and be received inside the first pipe unit 210, and then pivot the first pipe unit 210 relative to the rotating frame 200 and fold it for storage near the rotating frame 200, thereby reducing the volume of the photographic workbench.

[0041] Of course, in other embodiments, the vertical rod 310 can also be directly detached from the first pipe unit 210, and then the vertical rod 310 is inserted into the first pipe unit 210 to achieve storage. It should be noted that in order to facilitate the extraction of the vertical rod 310 from the first pipe unit 210, a part of the end of the vertical rod 310 extends out of the pipe orifice of the first pipe unit 210. Therefore, the fact that the vertical rod 310 of the present invention can be received in the lumen of the corresponding first pipe unit 210 should be understood as being received at least partially in the lumen of the corresponding first pipe unit 210.

[0042] See Figure 5 , in some embodiments of the present invention, a first reduced-diameter rod 311 is provided at the lower end of the vertical rod 310. A first ball head 312 with a diameter adapted to the lumen of the first pipe unit 210 is provided at the lower end of the first reduced-diameter rod 311. A first connection seat 220 is provided at the free end of the first pipe unit 210. The first connection seat 220 is provided with a first installation opening 221 for installing the first ball head 312 and the first reduced-diameter rod 311. The first installation opening 221 has a first positioning groove 222 matching the first reduced-diameter rod 311. A vertical through hole 223 through which the vertical rod 310 can pass is provided on the first connection seat 220. The vertical through hole 223 is communicated with both the first installation opening 221 and the lumen of the first pipe unit 210. The lifting and adjusting structure 320 is provided on the first connection seat 220.

[0043] See Figure 5, during assembly, first embed the first ball head 312 into the pipe orifice of the first pipe unit 210 along the first installation opening 221, and make the first reduced-diameter rod 311 enter the first positioning groove 222. It should be noted that the first reduced-diameter rod 311 and the first ball head 312 can be connected by a threaded connection. By driving the first reduced-diameter rod 311 to rotate relative to the first ball head 312, the wall plate near the first positioning groove 222 can be clamped between the first ball head 312 and the vertical rod 310. At this time, the first reduced-diameter rod 311 cannot displace in the width direction of the first positioning groove 222, thereby limiting the position of the vertical rod 310; when it is necessary to store the vertical rod 310 in the lumen of the first pipe unit 210, the vertical rod 310 swings so that the first reduced-diameter rod 311 disengages from the first positioning groove 222. As Figure 4 and Figure 5 shown, in this embodiment, the vertical rod 310 swings outwards by 90° so that the vertical rod 310 is collinear with the first pipe unit 210, and then the vertical rod 310 is inserted into the lumen of the first pipe unit 210 to realize storing the vertical rod 310 in the first pipe unit 210; conversely, when it is necessary to deploy the vertical rod 310, the vertical rod 310 is pulled out from the first pipe unit 210, and then the vertical rod 310 rotates upwards by 90° to be perpendicular to the first pipe unit 210, and the first reduced-diameter rod 311 enters the first positioning groove 222. The connection structure between the vertical rod 310 and the first pipe unit 210 can realize the quick storage or deployment of the vertical rod 310, and the use operation is convenient.

[0044] See Figure 6 , in some embodiments of the present invention, the lifting and adjusting structure 320 includes a movable clamping plate 321 and a threaded ejector rod 322. The movable clamping plate 321 is movably arranged in the first connecting seat 220 and is located in the vertical through hole 223. The movable clamping plate 321 can deform along the radial direction of the vertical through hole 223. The threaded ejector rod 322 is threadedly connected to the first connecting seat 220 and abuts against the movable clamping plate 321. It can be understood that the movable clamping plate 321 can be made into an arc-shaped plate that matches the circumferential wall surface of the vertical rod 310. The arc-shaped plate is made of a material with a certain elasticity such as plastic or metal. In the natural state, the arc-shaped plate can abut against the vertical rod 310 passing through the vertical through hole 223. When the threaded ejector rod 322 is tightened, the arc-shaped plate generates a deformation amount and presses the arc-shaped plate against the side wall of the vertical rod 310, using the frictional force to prevent the vertical rod 310 from moving up and down relative to the first connecting seat 220. When it is necessary to adjust the height position of the vertical rod 310, only need to loosen the threaded ejector rod 322, and then adjust the position of the vertical rod 310 on the first connecting seat 220, and then tighten the threaded ejector rod 322 again. The structure of the lifting and adjusting structure 320 is simple, the cost is low, and the adjustment operation is fast.

[0045] See Figure 7In some embodiments of the present invention, in order to further reduce the volume of the photography workbench of the present invention when stored, the bottom support frame 100 includes a mounting seat 110, a plurality of second tube units 120 pivotally connected to the mounting seat 110, and a support rod 130 movably connected to the free end of the second tube unit 120. The rotating frame 200 is rotatably arranged on the mounting seat 110 around a vertical axis. A second reducing rod 131 is provided at the upper end of the support rod 130. A second ball head 132 whose diameter matches the tube cavity of the second tube unit 120 is provided at the upper end of the second reducing rod 131. A second connecting seat 140 is provided at the free end of the second tube unit 120. The second connecting seat 140 is provided with a second mounting opening 141 for mounting the second ball head 132 and the second reducing rod 131. The second mounting opening 141 has a second positioning groove 142 matching the second reducing rod 131.

[0046] During assembly, the second ball head 132 is first inserted into the tube mouth of the second tube unit 120 along the second installation opening 141, and the second diameter reduction rod 131 is inserted into the second positioning groove 142. It should be noted that the second diameter reduction rod 131 and the second ball head 132 can be threadedly connected. By driving the second diameter reduction rod 131 to rotate relative to the second ball head 132, the wall plate near the second positioning groove 142 can be clamped between the second ball head 132 and the support rod 130. At this time, the second diameter reduction rod 131 cannot be displaced in the width direction of the second positioning groove 142, thereby limiting the position of the support rod 130. When the support rod 130 needs to be stored in the tube cavity of the second tube unit 120, the support rod 130 swings to disengage the second diameter reduction rod 131 from the second positioning groove 142.

[0047] like Figure 4 and Figure 7 As shown, in this embodiment, the vertical rod 310 is swung outward by 90° to make the support rod 130 and the second tube unit 120 collinear, and then the support rod 130 is inserted into the tube cavity of the second tube unit 120 to achieve the storage of the support rod 130 in the second tube unit 120, and then the whole composed of the second tube unit 120 and the support rod 130 is rotated relative to the mounting seat 110 to be folded and stored near the mounting seat 110. Conversely, when it is necessary to unfold the support rod 130, the support rod 130 is pulled out of the second tube unit 120, and then the support rod 130 is rotated downward by 90° to be perpendicular to the second tube unit 120, and the second diameter reduction rod 131 enters the second positioning groove 142. The connection structure between the support rod 130 and the second tube unit 120 can realize the rapid storage or unfolding of the support rod 130, and is easy to use and operate.

[0048] When the vertical rod 310 can be accommodated in the corresponding tube cavity of the first tube unit 210, and the support rod 130 can be accommodated in the corresponding tube cavity of the second tube unit 120, the photography workbench of the present invention can be folded into the following state after the connecting rod 410 is removed.Figure 4 The state shown, thus greatly reducing the volume of the photography workbench and facilitating packaging, transportation, and storage.

[0049] It should be noted that, for the convenience of pulling out the support rod 130 from the second pipe unit 120, a part of the end of the support rod 130 extends out of the pipe orifice of the second pipe unit 120.

[0050] See Figure 3 , in some embodiments of the present invention, a first shaft hole 201 is provided in the middle of the rotating frame 200, a second shaft hole 111 coaxial with the first shaft hole 201 is provided in the middle of the mounting seat 110, a rotating shaft assembly 150 passing through the first shaft hole 201 and the second shaft hole 111 is provided between the rotating frame 200 and the mounting seat 110, a circular ring guide groove 112 is provided on the upper end surface of the mounting seat 110, a first ball groove is provided on the lower end surface of the rotating frame 200, and a first ball 160 located in the circular ring guide groove 112 is movably arranged in the first ball groove. Through the above structure, the rotational accuracy of the relative rotation between the mounting seat 110 and the rotating frame 200 is relatively high, the rotational movement is smooth, and the service life is relatively long, and the load-bearing capacity is relatively strong.

[0051] See Figure 1 , in some embodiments of the present invention, in order to realize the function of supplementary lighting when photographing the items on the placing tray 600, a lighting device 700 corresponding to the placing tray 600 is further provided on the rotating frame 200.

[0052] In some embodiments, the lighting device 700 includes a third pipe unit 710 pivotally connected to the rotating frame 200, a vertical rod 720 is movably connected to the free end of the third pipe unit 710, and an annular supplementary light 730 is provided on the vertical rod 720.

[0053] In some embodiments, in order to realize the adjustment of the elevation angle of the annular supplementary light 730, a universal ball head is provided on the annular supplementary light 730, a ball head seat for installing the universal ball head is provided at the upper end of the vertical rod 720, and a locking screw is provided on the ball head seat. It can be understood that, in order to realize the effect that the entire photography workbench can be folded and stored, the annular supplementary light 730 can be detached from the vertical rod 720, the vertical rod 720 can be received in the lumen of the corresponding third pipe unit 710, and the connection manner between the vertical rod 720 and the third pipe unit 710 is the same as the connection manner between the vertical rod 310 and the first pipe unit 210, and details are not described further herein.
