Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Two embodiments provided by the present invention:

[0047] Embodiment 1

[0048] Synchronously adjust six supplementary lighting fixtures 400 to adjust the supplementary lighting range. Please refer to Figures 1 to 5 and Figure 12 , a live broadcast supplementary lighting device for item display, including a box body 100 and a box cover 200. The box body 100 is connected to a bracket, and the bracket is supported on the ground. The bracket is used to support the box body 100; six extension frames 300 are fixedly arranged in a circular array on the outer periphery of the box body 100. The outer peripheral opening of the box body 100 corresponds to the inner cavity of the extension frame 300. A screw rod 900 is arranged in the extension frame 300. One end of the screw rod 900 is rotatably connected to the extension frame 300 through a rotating shaft B901. The other end of the screw rod 900 is fixedly provided with a bevel gear B600. A bevel gear A500 is arranged in the box body 100. The bevel gear A500 is rotatably connected to the box body 100 through a rotating shaft A700. The rotating shaft A700 passes through the middle of the bevel gear A500 and is fixed to the bevel gear A500. The inner end of the rotating shaft A700 is rotatably connected to the box body 100. The outer end of the rotating shaft A700 is fixedly provided with a rotating handle A800. The bevel gear A500 is sequentially meshed and connected with six bevel gears B600; the box cover 200 is fixedly arranged on the box body 100. The box cover 200 can protect the bevel gear A500 and the bevel gear B600. The outer end of the rotating shaft A700 passes through the box cover 200, and the outer end of the rotating shaft A700 is rotatable relative to the box cover 200. The rotating handle A800 is located outside the box cover 200. The staff rotates the rotating handle A800, the rotating shaft A700 drives the bevel gear A500 to rotate, and the six bevel gears B600 meshed with the bevel gear A500 rotate accordingly, and the screw rod 900 rotates accordingly.

[0049] The outer peripheral opening of the box body 100 corresponds to the outer peripheral opening of the box cover 200. The connecting block 1100 is inserted and matched with the outer peripheral opening of the box cover 200. After the connecting block 1100 enters the outer peripheral opening of the box cover 200, the six supplementary lighting fixtures 400 form a complete ring.

[0050] The screw rod 900 is threadedly connected to the threaded hole on the moving block 1000. The side wall of the moving block 1000 contacts the inner wall of the extension frame 300, and the moving block 1000 can slide within the extension frame 300 and remains stable when sliding within the extension frame 300. A connecting block 1100 is provided on the outside of the moving block 1000, and a supplementary lighting fixture 400 is fixedly provided on the outside of the connecting block 1100. The supplementary lighting fixture 400 is selected and used by professionals according to the actual situation. The connector on the supplementary lighting fixture 400 is connected to an electric wire, and the electric wire plug is inserted into an external power socket. As the screw rod 900 rotates, the moving block 1000 slides along the screw rod 900 within the extension frame 300. At this time, the connecting block 1100 is fixed to the moving block 1000, thereby driving the connecting block 1100 and the supplementary lighting fixture 400 to move, so that the six supplementary lighting fixtures 400 expand to form a larger supplementary lighting range.

[0051] By providing the box body 100, the box cover 200, the extension frame 300, the supplementary lighting fixture 400, the bevel gear A 500, the bevel gear B 600, the rotating shaft A 700, the rotating handle A 800, the screw rod 900, the moving block 1000 and the connecting block 1100, the present invention has the advantages of providing six supplementary lighting fixtures 400 in a segmented manner, adjusting the positions of the six supplementary lighting fixtures 400 to supplement light, and the supplementary lighting effect can be adjusted according to actual use, and solves the problem of insufficient supplementary lighting effect for different products in different spaces and at different angles.

The rotation prevention fixing clip 201 includes a fixture and a threaded bolt for tightening the fixture, and the rotation prevention fixing clip 201 can clamp the rotating handle A 800. After the six supplementary lighting fixtures 400 are adjusted, the staff can turn the threaded bolt to make the fixture clamp the rotating handle A 800, so that the rotating handle A 800 is stable, thereby keeping the bevel gear A 500 stable, causing the bevel gear B 600 to be stable, and the supplementary lighting fixture 400 is kept stable.

[0053] Embodiment 2

[0054] Based on the technical content in the above Embodiment 1, another embodiment is proposed. Please refer to Figure 2 、 Figure 4 、 Figures 6 to 11, A live broadcast supplementary lighting device for item display. Inside the extension frame 300, two symmetrically distributed tracks 1400 are fixedly arranged. On the outer side of the moving block 1000, two symmetrically arranged sliding grooves 1002 are opened. The tracks 1400 are in sliding fit with the sliding grooves 1002, and the moving block 1000 can move along the tracks 1400. On the inner side of the connecting block 1100, two symmetrically distributed sliding blocks 1401 are fixedly arranged. The sliding blocks 1401 are in sliding fit with the grooves of the tracks 1400. When the connecting block 1100 and the moving block 1000 move together, the sliding blocks 1401 slide synchronously along the grooves of the tracks 1400. When the connecting block 1100 moves alone, the sliding blocks 1401 cooperate with the connecting block 1100 to slide along the grooves of the tracks 1400; the sliding blocks 1401 are T-shaped, and the sliding blocks 1401 are adapted to the grooves of the tracks 1400, and the T-shaped sliding blocks 1401 slide stably along the grooves of the tracks 1400.

[0055] The moving block 1000 and the connecting block 1100 are fixedly connected through a fixing structure 1300. The fixing structure 1300 includes a fixing block A1301, a fixing block B1302 and a connecting bar 1304. Two fixing blocks A1301 are symmetrically and fixedly arranged on the moving block 1000. Two fixing blocks B1302 are symmetrically and fixedly arranged on the connecting block 1100. The two fixing blocks A1301 and the two fixing blocks B1302 correspond one by one. Insertion bars 1303 are respectively inserted through the two fixing blocks B1302, and one end of each insertion bar 1303 is inserted into the fixing block A1301. The other ends of the two insertion bars 1303 are respectively fixedly connected to the connecting bar 1304. A spring 1305 is arranged between the fixing block B1302 and the connecting bar 1304. The spring 1305 is sleeved on the insertion bar 1303, and both ends of the spring 1305 are fixedly connected to the fixing block B1302 and the connecting bar 1304 respectively. When the moving block 1000 and the connecting block 1100 move synchronously, one end of the insertion bar 1303 is inserted into the fixing block A1301, and the moving block 1000 and the connecting block 1100 are fixed. Therefore, the moving block 1000 and the connecting block 1100 can move synchronously; when the connecting block 1100 is moved alone, the staff pulls the connecting bar 1304 outwards, the insertion bar 1303 moves accordingly, and the spring 1305 is stretched until one end of the insertion bar 1303 leaves the fixing block A1301, and the connecting block 1100 can be moved alone, and then the supplementary lighting fixture 400 can be moved alone.

[0056] An adjustment structure 1200 is connected between the connecting block 1100 and the screw rod 900. The adjustment structure 1200 includes a connecting column 1201, a mounting plate A 1202, a mounting plate B 1204, and a threaded ring 1206. The connecting column 1201 is fixedly arranged on the connecting block 1100. The mounting plate A 1202 is fixedly arranged at the top of the connecting column 1201. Both sides between the mounting plate B 1204 and the mounting plate A 1202 are fixedly connected through a connecting plate 1203. A spur gear 1205 is rotatably connected between the mounting plate B 1204 and the mounting plate A 1202 through a rotating shaft C 1209. The rotating shaft C 1209 passes through the middle of the spur gear 1205 and is fixed to the spur gear 1205. The end of the rotating shaft C 1209 is rotatably connected to the mounting plate A 1202. The threaded ring 1206 is threadedly sleeved on the screw rod 900. A straight rack 12061 is arranged on the outer periphery of the threaded ring 1206. The straight rack 12061 is meshed and connected with the spur gear 1205. A bolt 1208 is threadedly penetrated through the mounting plate B 1204. The penetrated end of the bolt 1208 is inserted and matched with a jack 12051 opened on the spur gear 1205. When the moving block 1000 and the connecting block 1100 move synchronously, the penetrated end of the bolt 1208 is inserted into the jack 12051 opened on the spur gear 1205, thereby fixing the spur gear 1205. The threaded ring 1206 meshed with the spur gear 1205 is in a positioned state. When the screw rod 900 rotates, the moving block 1000 and the threaded ring 1206 can be regarded as a whole, and the moving block 1000 and the threaded ring 1206 move synchronously along the screw rod 900. When the connecting block 1100 is moved alone, the moving block 1000 and the connecting block 1100 are in an unfixed state. The bolt 1208 is screwed out until it no longer positions the spur gear 1205. The staff rotates the spur gear 1205, and the threaded ring 1206 meshed with the spur gear 1205 rotates accordingly, causing the threaded ring 1206 to move along the screw rod 900, thereby driving the connecting block 1100 to move alone and adjusting the position of a single supplementary lighting fixture 400.

[0057] The mounting plate A 1202 and the mounting plate B 1204 are respectively in limit fit with the upper and lower ends of the meshing section of the threaded ring 1206. The spur gear 1205 remains in a meshed state with the threaded ring 1206. When the threaded ring 1206 moves along the screw rod 900, it can drive the spur gear 1205 to move, thereby driving the connecting block 1100 and the supplementary lighting fixture 400 to move.

[0058] By providing the connecting block 1100, the adjustment structure 1200, the fixing structure 1300, the track 1400, and the slider 1401, the present invention has the advantages that the position of a single supplementary lighting fixture 400 can be adjusted separately, and after the six supplementary lighting fixtures 400 are expanded and adjusted, a single supplementary lighting fixture 400 can be locally adjusted to optimize the supplementary lighting effect.

[0059] Refer to Figure 7 and Figure 8, at both ends of the outer bottom of the moving block 1000, limiting blocks 1001 are fixedly arranged respectively. At both ends of the bottom of the connecting block 1100, limiting grooves 1101 are respectively opened. The limiting blocks 1001 are in limiting cooperation with the limiting grooves 1101. When it is necessary to synchronize the moving block 1000 and the connecting block 1100, the moving block 1000 and the connecting block 1100 are butted. After the limiting blocks 1001 and the limiting grooves 1101 are butted, it indicates that the moving block 1000 and the connecting block 1100 are butted in place, which is convenient for the fixing structure 1300 to fix the moving block 1000 and the connecting block 1100.

[0060] Refer to Figure 10 and Figure 11 , a turning handle B1207 is rotatably arranged on the mounting plate B1204, and the turning handle B1207 is fixedly connected with the rotating shaft C1209. The staff can rotate the turning handle B1207 to drive the rotating shaft C1209 to rotate, causing the spur gear 1205 to rotate, which is more convenient than directly rotating the spur gear 1205.

[0061] Refer to Figure 11 , on the opposite sides of the mounting plate A1202 and the mounting plate B1204 corresponding to the meshing sections with the threaded ring 1206, arc-shaped blocks 1210 are fixedly arranged respectively. Annular grooves 12062 are respectively opened at the upper and lower ends of the threaded ring 1206. The arc-shaped blocks 1210 can slide in the annular grooves 12062. There is a gap between the mounting plate A1202 and the mounting plate B1204 and the meshing sections of the threaded ring 1206; the resistance of the limit when the threaded ring 1206 rotates is reduced.

[0062] Working principle: The box body 100 is connected to the support, and the support is supported on the ground. When adjusting the positions of the six supplementary lighting fixtures 400 for supplementary lighting, the worker rotates the turning handle A800, the rotating shaft A700 drives the bevel gear A500 to rotate, and the six bevel gears B600 meshing with the bevel gear A500 rotate accordingly, and the screw rod 900 rotates. With the rotation of the screw rod 900, the moving block 1000 slides along the screw rod 900 within the extension frame 300. One end of the insertion bar 1303 is inserted into the fixed block A1301. At this time, the connecting block 1100 is fixed to the moving block 1000. When the moving block 1000 and the connecting block 1100 move synchronously, the inserted end of the bolt 1208 is inserted into the jack 12051 opened on the spur gear 1205, thereby fixing the spur gear 1205. The threaded ring 1206 meshing with the spur gear 1205 is in a positioned state. When the screw rod 900 rotates, the moving block 1000 and the threaded ring 1206 can be regarded as a whole, and the moving block 1000 and the threaded ring 1206 move synchronously along the screw rod 900. The moving block 1000 can move along the track 1400, and the slider 1401 slides along the groove of the track 1400 synchronously, driving the connecting block 1100 and the supplementary lighting fixture 400 to move, so that the six supplementary lighting fixtures 400 expand to form a larger supplementary lighting range to meet the supplementary lighting requirements. After the six supplementary lighting fixtures 400 are adjusted, the worker can turn the threaded bolt to clamp the turning handle A800, making the turning handle A800 stable, thereby keeping the bevel gear A500 stable, causing the bevel gear B600 to be stable, and the screw rod 900 does not rotate.

[0063] When it is necessary to locally adjust a single supplementary lighting fixture 400 after the six supplementary lighting fixtures 400 are expanded and adjusted, the worker pulls the connecting bar 1304 outwards, and the insertion bar 1303 moves accordingly, and the spring 1305 is stretched until one end of the insertion bar 1303 leaves the fixed block A1301, and the moving block 1000 and the connecting block 1100 are no longer fixed, and the bolt 1208 is unscrewed until it no longer positions the spur gear 1205; the worker rotates the turning handle B1207 to drive the rotating shaft C1209 to rotate, causing the spur gear 1205 to rotate, and the threaded ring 1206 meshing with the spur gear 1205 rotates accordingly, causing the threaded ring 1206 to move along the screw rod 900, thereby driving the connecting block 1100 to move alone, and the slider 1401 cooperates with the connecting block 1100 to slide along the groove of the track 1400 to adjust the position of a single supplementary lighting fixture 400; after the position of a single supplementary lighting fixture 400 is adjusted, it cooperates with the six supplementary lighting fixtures 400 to perform supplementary lighting on the product for live broadcast.
