[0046] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0048] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] This utility model provides an adjustment mechanism for mounting and adjusting photographic equipment on a mounting bracket.

[0050] Please see Figure 1 and Figure 2 The adjustment mechanism includes a transition assembly 10 and a handle assembly 20. The transition assembly 10 includes at least two connectors 11 and a connecting shaft 12.

[0051] This embodiment uses two connectors 11 as an example for illustration. One connector 11 is used to connect the photographic equipment 2000, and the other connector 11 is used to connect the mounting bracket. In this application, the photographic equipment 2000 includes, but is not limited to, photographic lighting equipment and lighting accessories, specifically including, but not limited to, flat panel film and television lights, softboxes, reflectors, diffusers, dimmers, flash units, film and television inflatable lights, etc. The mounting bracket can be a vertical bracket, a suspended bracket, etc. In other embodiments, three connectors 11 can also be provided, with one connector 11 used to connect the photographic equipment and the other two connectors 11 used to connect the mounting bracket. The specific number of connectors 11 can be set according to actual needs and is not limited here.

[0052] Two connectors 11 are rotatably mounted on the connecting shaft 12, so the user can adjust the camera equipment by 2000 degrees by rotating the connectors 11 to adapt to different photography and videography environments.

[0053] Specifically, the connecting shaft 12 includes a shaft body 121. The connecting member 11 is provided with a pivot hole 111. The shaft body 121 passes through the pivot hole 111, allowing the connecting member 11 to rotate around the shaft body 121. It is understood that the two connecting members 11 are arranged at intervals or adjacent to each other along the axial direction of the shaft body 121.

[0054] The connecting shaft 12 includes a limiting part 122, which is disposed at the end of the shaft body 121. The size of the limiting part 122 is larger than the diameter of the shaft body 121 in the axial direction perpendicular to the shaft body 121. The limiting part 122 abuts against one of the connecting members 11 to prevent the connecting member 11 from falling off the shaft body 121.

[0055] For ease of description, the connector 11 that abuts against the limiting part 122 is defined as the first connector 112, and the other connector 11 is defined as the second connector 113.

[0056] The handle assembly 20 is disposed on the end of the shaft 121 away from the limiting part 122. This corresponds to two connecting members 11 being arranged between the handle assembly 20 and the limiting part 122. The handle assembly 20 is capable of moving back and forth along the axial direction of the shaft 121.

[0057] Specifically, moving the handle assembly 20 forward means that it can move towards the second connector 113 to approach it until it abuts against it, thus bringing the second connector 113 and the first connector 112 closer together and tightly abutting, restricting the relative rotation of the two connectors 11, and achieving locking and fixing of the two connectors 11. Conversely, moving the handle assembly 20 backward means that it can move away from the second connector 113 to release the pressure on it, allowing the two connectors 11 to release their abutment and return to a state where they can rotate relative to each other. At this point, the user can readjust the first connector 112 and the second connector 113 according to their needs.

[0058] See Figure 2 and Figure 3 In some embodiments, the connecting shaft 12 includes a lug 123 that protrudes from the shaft body 121. The end of the first connecting member 112 is disposed between the lug 123 and the limiting portion 122, and the end of the second connecting member 113 is disposed on the lug 123. The shape of the pivot hole 111 on the first connecting member 112 and the second connecting member 113 is the same as or approximately the shape of the cross-section of the lug 123 and the shaft body 121 after they are joined, so that the end of the first connecting member 112 can be smoothly assembled between the lug 123 and the limiting portion 122, and the end of the second connecting member 113 can be disposed on the lug 123.

[0059] For example, the first connector 112 is used to connect photographic equipment, and the second connector 113 is used to connect a mounting bracket. When the second connector 113 is connected to the mounting bracket, the lug 123 and the pivot hole 111 on the second connector 113 work together to restrict the rotation of the connecting shaft 12, thus fixing the connecting shaft 12 in the axial direction perpendicular to the shaft body 121. This configuration improves operational portability; the user only needs to control the handle assembly 20 to lock and unlock the two connectors 11, without needing to control the movement of the handle assembly 20 on the shaft body 121 while simultaneously fixing the connecting shaft 12.

[0060] Furthermore, when the first connector 112 and the second connector 113 are assembled onto the connecting shaft 12, the first connector 112 and the second connector 113 are typically arranged at an included angle. This means that the first connector 112 will rotate relative to the connecting shaft 12 at a certain angle, causing the pivot hole 111 on the first connector 112 to misalign with the lug 123. This effectively fixes the connecting shaft 12 along the axial direction of the shaft body 121, preventing the connecting shaft 12 from falling off.

[0061] In some embodiments of this application, the connector 11 includes a connecting body 114 and a mating portion 115 disposed at one end of the connecting body 114. A pivot hole 111 is disposed on the mating portion 115. The mating portions 115 in the first connector 112 and the mating portions 115 in the second connector 113 have planar surfaces that face each other. This is beneficial for increasing the contact area between the first connector 112 and the second connector 113, reducing stress concentration, and ensuring that the first connector 112 and the second connector 113 are subjected to balanced forces.

[0062] See Figure 2 and Figure 3 In some embodiments, the adjustment mechanism 100 includes a first washer 30 disposed between the two connectors 11. Therefore, when the handle assembly 20 moves toward the connectors 11 so that each connector 11 abuts against the first washer 30 when the two connectors 11 are relatively close. The first washer 30 prevents wear caused by direct contact between the first connector 112 and the second connector 113, thus extending the service life of the first connector 112 and the second connector 113.

[0063] In some embodiments, the adjustment mechanism 100 includes a second washer 40, through which the handle assembly 20 can abut against the second connector 113. The second washer 40 prevents wear caused by direct contact between the handle assembly 20 and the second connector 113, thus extending the service life of the handle assembly 20 and the second connector 113.

[0064] In some embodiments, the connector 11 includes a fixing knob 116 and a connecting groove 117 disposed on the connecting body 114. The opening of the connecting groove 117 may face away from the mating portion 115. A support rod in the mounting bracket can pass through the opening of the connecting groove 117 and be received in the connecting groove 117. The end of the fixing knob 116 passes through the connecting body 114 and abuts against the support rod, thereby fixing the connector 11 to the external mounting bracket.

[0065] In some embodiments, mounting holes 118 may be provided on opposite sides of the connecting body 114. The mounting holes 118 communicate with the connecting groove 117, allowing the support rod in the mounting bracket to pass through one mounting hole 118 into the connecting groove 117 and out through the other mounting hole 118, thus connecting the connecting body 114 to the mounting bracket. A fixing knob 116 passes through the connecting body 114 and abuts against the support rod to fix the connector 11 to the mounting bracket. The mounting holes 118 expand the applicability of the connector 11, allowing it to be installed not only at the end of the support rod but also in the middle. Users can choose the installation method of the connector 11 and the mounting bracket according to their actual usage scenario.

[0066] The first connector 112 connected to the photographic equipment 2000 can have the same or similar structure as the second connector 113, so that the photographic equipment 2000 can be plugged into the connector body 114, and the photographic equipment 2000 and the connector 11 can be fixedly connected by the fixing knob 116.

[0067] The handle assembly 20 includes an adjusting member 21 and a handle 22. The adjusting member 21 is disposed on the shaft 121 of the connecting shaft 12. The handle 22 is disposed on the adjusting member 21. An external force drives the handle 22, which can cause the adjusting member 21 to move back and forth along the axial direction of the shaft 121, so that the adjusting member 21 moves closer to or further away from the connecting member 11, so that the adjusting member 21 abuts against the connecting member 11 and the two connecting members are tightly fixed at a set angle, or so that the two connecting members 11 can move away from each other and release the abutment state, so that the two connecting members 11 can rotate relative to each other to adjust the angle of the photographic equipment 2000 on the connecting member 11.

[0068] In some embodiments, the shaft 121 has an external thread 124, and the adjusting member 21 has an internal thread. The internal thread and the external thread 124 are adapted to each other, allowing the adjusting member 21 to be screwed onto the connecting shaft 12, so that the adjusting member 21 can move back and forth along the axial direction of the connecting shaft 12. When the adjusting member 21 rotates forward on the connecting shaft 12, the adjusting member 21 moves towards the connecting member 11 along the axial direction of the shaft 121 in the connecting shaft 12, so that the two connecting members 11 come closer to each other and are locked together. Correspondingly, when the adjusting member 21 rotates in the opposite direction, the adjusting member 21 moves away from the connecting member 11 along the axial direction of the shaft 121, so that the two connecting members 11 can move away from each other and the locking state is released. At this time, the connecting member 11 connecting the photographic equipment 2000 can be rotated smoothly to adjust the photographic equipment 2000 to the desired direction.

[0069] In some embodiments of this application, the adjusting member 21 includes a main body 211 and a connecting portion 212. The main body 211 has a mounting position. The connecting portion 212 is disposed in the mounting position. An internal thread is provided on the connecting portion 212. During the frequent installation and removal of the handle assembly 20 on the connecting shaft 12, the internal thread is prone to wear. Therefore, the separate design of the main body 211 and the connecting portion 212 reduces maintenance costs; the user only needs to replace the worn connecting portion 212, without having to replace the entire adjusting member 21.

[0070] The handle 22 is used by the user to grip and facilitates the rotation of the adjusting component 21. The handle 22 is mounted on the adjusting component 21 and can move relative to the adjusting component 21 to fix or release it from the adjusting component 21. Therefore, when the angle of the connecting component 11 needs to be adjusted, and the distance between the handle 22 and the photographic equipment 2000 is too small to affect the rotation of the handle 22, the user can release the handle 22 from the adjusting component 21, adjust the handle 22 to a suitable position, and then install the handle 22 and the adjusting component 21 together.

[0071] Please see Figure 3 and Figure 4 In some embodiments, the handle 22 includes a body 221 and a mounting portion 222 provided on the body 221. The main body 211 of the adjusting member 21 is provided with an assembly portion 213. The mounting portion 222 engages with the assembly portion 213 to fix the handle 22 to the main body 211 of the adjusting member 21.

[0072] For example, the mounting part 222 is a mounting groove 222a. The assembly part 213 is an assembly tooth 213a that can engage with the mounting groove 222a, so that the handle 22 is fixed to the main body 211, and when an external force drives the handle 22, it can drive the adjusting member 21 to move back and forth along the axial direction of the connecting shaft 12. The number of mounting grooves 222a and the number of teeth of the assembly tooth 213a can be in a one-to-many, many-to-one, or many-to-many relationship, so that after the handle 22 rotates relative to the adjusting member 21 at a certain angle, the handle 22 can still be assembled and fixed on the main body 211 of the adjusting member 21.

[0073] For example, there is one mounting slot 222a and multiple mounting teeth 213a. The multiple mounting teeth 213a are spaced apart along the circumference of the main body 211. When the angle of the handle 22 needs to be adjusted, simply place another mounting tooth 213a into the mounting slot 222a.

[0074] Alternatively, multiple mounting slots 222a may be provided, and one mounting tooth 213a may be provided. The multiple mounting slots 222a are spaced apart circumferentially along the body 221. When the angle of the handle 22 needs to be adjusted, simply place the mounting tooth 213a into another mounting slot 222a.

[0075] Alternatively, multiple mounting slots 222a and multiple assembly teeth 213a may be provided. The number of teeth in the assembly teeth 213a is less than or equal to the number of mounting slots 222a. For example, see... Figure 5 When the number of teeth on the mounting teeth 213a is the same as the number of teeth on the mounting groove 222a, each mounting tooth 213a can be locked into the mounting groove 222a in a one-to-one correspondence, thereby achieving a stable connection between the handle 22 and the main body 211 of the adjusting member 21. The mounting groove 222a and the mounting teeth 213a are both provided in multiples to help balance the pressure on the adjusting member 21 and to make the rotation of the handle 22 more easily drive the rotation of the adjusting member 21. The specific number of teeth on the mounting teeth 213a can be set according to actual needs.

[0076] It is understood that protrusions 222b are formed between multiple mounting slots 222a, and grooves 213b are formed between multiple mounting teeth 213a. While the mounting teeth 213a are engaged in the mounting slots 222a, the protrusions 222b are accommodated in the grooves 213b, thus achieving a stable connection between the handle 22 and the main body 211 in the adjusting member 21.

[0077] In other embodiments, the number of protrusions 222b and the number of grooves 213b can be in a one-to-many, many-to-one, or many-to-many relationship. The sizes of the protrusions 222b and the grooves 213b are matched. When the number of protrusions 222b and the number of grooves 213b are in a many-to-many relationship, the number of protrusions 222b is less than or equal to the number of grooves 213b, and for each rotation of the handle 22 relative to the adjusting member 21 by one stop, each of all protrusions 222b can be aligned with a corresponding groove in the groove 213b. Figure 6 As shown, the handle 22 has 3 protrusions 222b and the adjusting member 21 has 15 grooves. In other embodiments, the protrusions 222b can also be 1, 2, etc.

[0078] It should be noted that in other embodiments, the handle 22 and the main body 211 of the adjusting member 21 may have other detachable connection methods, and after the handle 22 is detached from the main body 211, the handle 22 can rotate relative to the main body 211 and be installed on the main body 211 at another angle. For example, the mounting part 222 may also be a mounting post protruding from the handle 22 body 221, and the assembly part 213 may be an assembly groove recessed into the surface of the main body 211 of the adjusting member 21. The assembly groove may be an arc-shaped groove, which includes an arc-shaped section and a locking area. The mounting post can move along the arc-shaped section to the locking area to fix the handle 22. The number of mounting posts and the number of assembly grooves may be in a one-to-many, many-to-one, or many-to-many relationship, so that after the handle 22 rotates relative to the adjusting member 21 at a certain angle, the handle 22 can still be assembled on the main body 211 of the adjusting member 21.

[0079] See Figure 2 and Figure 3 In some embodiments, the adjusting member 21 includes a shaft portion 214, one end of which is connected to the main body 211. The axis of the shaft portion 214 may be collinear with the axis of the connecting shaft 12. When the handle 22 is released from its fixation to the main body 211, the handle 22 can rotate about the axis of the shaft portion 214. In other words, the handle 22 can rotate about the shaft portion 214 and relative to the main body 211 without disengaging from the adjusting member 21, thus preventing the handle 22 from completely detaching from the adjusting member 21 and being accidentally lost.

[0080] Exemplarily, the handle assembly 20 includes a retainer 23. The handle 22 includes a flange 223 and a through hole 224 disposed on the body 221. The flange 223 is disposed on the inner peripheral wall of the body 221 corresponding to the through hole 224, and extends toward the center of the through hole 224. The flange 223 may be disposed circumferentially along the body 221, thereby forming a limiting hole. The shaft portion 214 of the adjusting member 21 passes through the through hole 224. The retainer 23 is disposed on the shaft portion 214, and the flange 223 is arranged between the retainer 23 and the body 211. In the axial direction perpendicular to the shaft portion 214, the diameter of the retainer 23 is larger than the diameter of the limiting hole. Therefore, after the handle 22 is separated from the body 211 of the adjusting member 21, the retainer 23 can prevent the handle 22 from separating from the shaft portion 214 of the adjusting member 21.

[0081] In some embodiments, the handle assembly 20 includes an elastic element 24 that can be sleeved on the shaft portion 214. One end of the elastic element 24 abuts against the flange 223, and the other end abuts against the retainer 23.

[0082] Combination Figure 3 In this embodiment, the specific disassembly process of the handle 22 and the main body 211 in the adjusting member 21 is as follows: while the user presses the fixing member 23 with his thumb, he holds the handle 22 with his other fingers and applies force to move the handle 22, so that the handle 22 moves away from the main body 211 until the mounting teeth 213a on the main body 211 are completely disengaged from the mounting groove 222a in the handle 22. At this time, the handle 22 can rotate a certain angle relative to the shaft 214.

[0083] As the handle 22 moves away from the main body 211, the elastic element 24 is elastically compressed. After the handle 22 is adjusted to the appropriate direction, the user releases the handle 22, and the elastic element 24 rebounds and elastically extends, thereby resetting the handle 22 and re-engaging and fixing it with the main body 211.

[0084] Please see Figure 7This application also provides a support system 1000, including a connecting mechanism 200 and the aforementioned adjusting mechanism 100. The connecting mechanism 200 is used to connect photographic equipment 2000. A connector 11 in the adjusting mechanism 100 is connected to the connecting mechanism 200.

[0085] Specifically, the connecting mechanism 200 includes a connecting rod 50 and a connecting assembly 60. One end of the connecting rod 50 is connected to a connector 11, and the other end of the connecting rod 50 is connected to the connecting assembly 60. The connecting assembly 60 is used to connect the photographic equipment 2000. As mentioned above, one end of the connecting rod 50 can be inserted into the connecting groove 117 on the connector 11, or pass through the mounting hole 118 on the connector 11, and then the connecting rod 50 is pressed against the connecting rod using the fixing knob 116 to fix the connecting rod 50 to the connector 11.

[0086] See Figure 8 In some embodiments, the connecting mechanism 200 includes a crossbeam 70, and the connecting rod 50 is connected to the connecting assembly 60 through the crossbeam 70. Multiple connecting assemblies 60 are provided, spaced apart on the crossbeam 70. Each connecting assembly 60 is correspondingly connected to a photographic device 2000.

[0087] The photographic equipment 2000 connected by multiple connecting components 60 may be the same or different. The photographic equipment 2000 includes, but is not limited to, photographic lighting equipment and lighting accessories, specifically including, but not limited to, flat panel film and television lights, softboxes, reflectors, light filters, dimmers, flash units, film and television inflatable lights, etc.

[0088] This embodiment uses an example where there are two connecting components 60, and each connecting component 60 connects to a flat panel video light for the photographic equipment 2000. See [link to documentation]. Figure 9 The 70mm crossbeam allows multiple flat panel TV lights to be spliced ​​together to form a single unit, thereby achieving a larger area of ​​lighting effect.

[0089] Please see Figure 10 and Figure 11 The connecting rod 50 includes a rod body 51. A groove 52 is provided at the end of the rod body 51 that connects to the connector 11. A fixing knob 116 on the connector 11 abuts against the wall of the groove 52. The groove 52 is designed so that if the fixing knob 116 is accidentally pressed, causing the connecting rod 50 to loosen, the end of the fixing knob 116 can abut against the side wall of the groove 52, thereby mitigating or preventing the connecting rod 50 from falling out of the connecting groove 117 in the connector 11.

[0090] See Figure 12 and Figure 13The end of the rod 51 furthest from the settling groove 52 is provided with a fastening hole 53. The crossbeam 70 is provided with a through hole 71. The connecting mechanism 200 includes a fastener 80. The fastener 80 passes through the through hole 71 and is housed in the fastening hole 53 to achieve the connection between the crossbeam 70 and the connecting rod 50. The fastener 80 can be a bolt, stud, etc.

[0091] In some embodiments, the connecting rod 50 includes an extension 54 disposed on the outer periphery of the rod body 51 and extending in a direction opposite to the axis of the rod body 51. The extension 54 abuts against the surface of the crossbeam 70. The extension 54 increases the contact area between the connecting rod 50 and the crossbeam 70, which helps to improve the connection stability between the connecting rod 50 and the crossbeam 70.

[0092] See Figure 11 and Figure 13 In some embodiments, at least one positioning element 72 is provided on the crossbeam 70. The positioning element 72 protrudes from the surface of the crossbeam 70. A positioning groove is provided on the extension 54 or the rod 51. When the connecting rod 50 and the crossbeam 70 are connected by the fastener 80, the positioning element 72 is accommodated in the positioning groove. This arrangement can balance the pressure and avoid stress concentration.

[0093] See Figure 14 and Figure 15 The connecting assembly 60 includes a connecting plate 61 and a protruding post 62 protruding from the connecting plate 61. The protruding post 62 is provided with a first mounting hole 621, and the crossbeam 70 is provided with a second mounting hole 73. The bolt 90 passes through the second mounting hole 73 and is accommodated in the first mounting hole 621 to realize the connection between the connecting plate 61 and the crossbeam 70.

[0094] In some embodiments, the connecting assembly 60 includes a reinforcing plate 63, one side of which is connected to the connecting plate 61 and the adjacent other side is connected to the protrusion 62 to enhance the structural strength of the connecting assembly 60.

[0095] See Figure 16 The connecting mechanism 200 includes a mounting member 64, which includes a connecting rod 641 and a head 642 located at one end of the connecting rod 641. The diameter of the head 642 is larger than the diameter of the connecting rod 641. The other end of the connecting rod 641 is connected to a connecting plate 61.

[0096] join Figure 17 In some embodiments, the connecting plate 61 is provided with a third mounting hole 611. The connecting rod 641 is a screw rod, which passes through the third mounting hole 611 and connects with the nut 612, thereby fixing the connecting member 11 to the connecting plate 61. In other embodiments, the connecting rod 641 can also be welded to the connecting plate 61.

[0097] See Figure 18The backplate 204 of the photographic equipment 2000 is provided with a fixing part 201 adapted to the mounting member 64. The fixing part 201 includes a first hole 201a and a second hole 201b, which are connected, and the diameter of the first hole 201a is larger than the diameter of the second hole 201b. The connecting rod 641 of the mounting member 64 passes through the first hole 201a, causing the head 642 in the mounting member 64 to move into the interior of the photographic equipment 2000, and then the connecting assembly 60 is moved as a whole to move the connecting rod 641 of the mounting member 64 into the second hole 201b. At this time, the surface of the backplate 204 abuts against the head 642 in the mounting member 64 to prevent the head 642 from disengaging, thereby realizing the connection between the connecting assembly 60 and the photographic equipment 2000.

[0098] Multiple mounting members 64 may be provided. The multiple mounting members 64 are arranged at intervals along the circumference of the connecting plate 61. Correspondingly, multiple fixing parts 201 are also provided to increase the contact area between the connecting assembly 60 and the photographic equipment 2000, which is conducive to the balanced distribution of force and enhances the connection stability between the connecting assembly 60 and the photographic equipment 2000.

[0099] See Figure 14 , Figure 17 and Figure 18 In some embodiments, a positioning post 613 protrudes from the side surface of the connecting plate 61 opposite to the protruding post 62. A positioning hole 202 is provided on the back plate of the photographic equipment 2000. The extending direction of the positioning hole 202 is the same as that of the first hole 201a towards the second hole 201b, to ensure smooth movement of the mounting member 64 in the connecting assembly 60 on the photographic equipment 2000. The positioning post 613 further increases the force-bearing points of the connecting assembly 60 and the photographic equipment 2000, further balancing the pressure.

[0100] See Figure 16 In some embodiments, the connecting component 60 includes an unlocking member 65, which is used to fix the connecting plate 61 after the mounting member 64 is assembled into the second hole 201b in the fixing part 201, so as to prevent the bracket system 1000 from vibrating under external force, causing the connecting member 11 to move and causing the connecting rod 641 of the mounting member 64 to move out of the second hole 201b.

[0101] Specifically, see Figure 16 and Figure 17 The unlocking component 65 includes a column 651, a spring 652, and an operating part 653. A connecting plate 61 has a protruding mounting protrusion 66 for accommodating the column 651. A first locking hole 614 is provided on the connecting plate 61.

[0102] See Figure 19 and Figure 20One end of the column 651 can pass through the first locking hole 614 and extend beyond the surface of the connecting plate 61, while the other end of the column 651 extends beyond the surface of the mounting protrusion 66 and connects to the operating part 653. A stepped portion 654 is provided on the outer periphery of the column 651. The mounting protrusion 66 has an inner edge portion 661 that extends towards the axis of the column 651. A spring 652 is sleeved on the outside of the column 651, with one end abutting against the stepped portion 654 and the other end abutting against the inner edge portion 661. The operating part 653 is located outside the mounting protrusion 66 and abuts against the mounting protrusion 66 to prevent the column 651 from disengaging from the connecting plate 61 through the first locking hole 614 under the elastic extension of the spring 652.

[0103] See Figure 18 and Figure 20 The back panel of the photographic equipment 2000 is provided with a second locking hole 203. The first locking hole 614 and the second locking hole 203 are provided correspondingly so that the column 651 can be accommodated in the second locking hole 203, thereby fixing the connecting assembly 60 to the photographic equipment 2000.

[0104] Therefore, in this embodiment, the process of assembling and disassembling the connecting component 60 and the photographic equipment 2000 is as follows: the operating part 653 is controlled to move away from the connecting plate 61, causing the column 651 to disengage from the second locking hole 203 on the back plate. At this time, the connecting plate 61 or the photographic equipment 2000 is controlled to move, so that the mounting part 64 on the connecting plate 61 moves from the second hole 201b in the fixing part 201 to the first hole 201a. Then, the connecting plate 61 is controlled to move away from the photographic equipment 2000, so that the head 642 of the mounting part 64 is moved out of the first hole 201a of the fixing part 201, thereby realizing the separation of the connecting component 60 and the photographic equipment 2000.

[0105] Understandably, the installation process of the connecting component 60 and the photographic equipment 2000 is as follows: the operating part 653 is controlled to move away from the connecting plate 61, causing the column 651 to disengage from the second locking hole 203 on the back plate; simultaneously, the head 642 of the mounting part 64 is aligned with the first hole 201a in the fixing part 201 of the photographic equipment 2000, and the connecting mechanism 200 is controlled to move towards the photographic equipment 2000, or the photographic equipment 2000 is controlled to move towards the photographic equipment 2000. The head 642 moves toward the connecting mechanism 200 so that it passes through the first hole 201a and the connecting rod 641 is accommodated in the first hole 201a. Then, the connecting rod 641 in the mounting member 64 is moved from the first hole 201a to the second hole 201b. Finally, the operating part 653 is released so that the column 651 is reset under the elastic extension of the spring 652 and passes through the first locking hole 614 on the connecting plate 61 and is accommodated in the second locking hole 203 on the photographic equipment 2000.

[0106] See Figure 8 Two flat panel TV lights can be joined horizontally, meaning their widest edges meet. See Figure 21 Two flat panel video lights can also be vertically joined, meaning their long sides are joined together. In this case, the connecting component 60 in the bracket system 1000 can still connect and fix the flat panel video lights. Figure 8 In the middle, the direction in which the first hole 201a in the fixing part 201 faces the second hole 201b is the same as the extending direction of the crossbeam 70. Figure 21 In the middle, the direction of the first hole 201a facing the first hole 201a is perpendicular to the extension direction of the crossbeam 70.

[0107] The bracket system 1000 in this application, compared to the traditional combination and splicing method of a U-shaped bracket plus a frame for fixing multiple flat panel video lights, uses a connecting component 60 instead of a frame and a crossbeam 70 instead of a U-shaped bracket, resulting in a simpler structure and lighter weight. Furthermore, this application, by setting an adjustment mechanism 100, enables adjustment of the angle and direction of the photographic equipment 2000. This angle is typically adjusted to the pitch angle of the photographic equipment 2000. Further, by setting the handle 22 and the adjustment component 21 in the handle assembly 20, the user can adjust the angle of the handle 22 to avoid interference between the handle 22 and the photographic equipment 2000 or the mounting bracket, ensuring that the user can smoothly fix the angle of the connecting component 11 in the adapter assembly 10 using the handle 22.

[0108] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.
