DETAILED DESCRIPTION
[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0017] The embodiments are as follows Figures 1-4As shown, it comprises a reflector 1, which is an elastic plate and the reflecting angle is adjustable. The reflector 1 is provided with an elastic edge 2 on the circumferential side wall, the reflector 1 is connected with the elastic edge 2, the elastic edge 2 is used to connect the support adjusting assembly for adjusting the reflecting angle of the reflector 1. In this embodiment, the bending degree of the elastic edge 2 is adjusted, and the elastic edge 2 can further drive the reflector 1 to bend after bending. Compared with the straight reflector or the curved reflector on the market which cannot adjust the bending degree, the reflecting intensity can be flexibly adjusted according to the distance of the light source (such as close-up and panoramic shooting), and the variable curvature can match the light and shadow requirements of different face shapes, for example, wide-angle scattered light is needed for round face, and narrow-angle concentrated light is needed for thin face, which greatly expands the use scene of the existing arc-shaped reflector.
[0018] The support adjusting assembly comprises two pairs of supporting legs 3 fixed at the bottom of the elastic edge 2, the supporting legs 3 located at the bottom of the narrow edge of the reflector 1 are fixedly connected with a driven connecting rod 4, and the two driven connecting rods 4 are parallel to each other and symmetric to the middle axis of the long edge of the reflector 1. A plurality of driving connecting rods 5 are rotatably connected to each driven connecting rod 4, one end of the driving connecting rod 5 rotates around the middle axis of the driven connecting rod 4, and the other end of the driving connecting rod 5 is connected with a rotary driving mechanism. The driving connecting rods 5 are in two pairs, and the two pairs of driving connecting rods 5 are symmetric to the middle axis of the long edge of the elastic reflector 1. When the driving connecting rods 5 rotate upward, the driven connecting rods 4 will be subjected to an upward force, thereby lifting the height of the driven connecting rods 4. When the driven connecting rods 4 on both sides are lifted upward, the elastic edge 2 together with the elastic reflector 1 will be bent to the middle part, thereby increasing the bending degree.
[0019] The rotary driving mechanism comprises a shell box body 6, four gear columns 7 are arranged in the shell box body 6 and are engaged with each other, the two ends of the gear columns 7 are rotatably connected to the shell box body 6, and a rotating shaft protruding from the shell box body 6 is coaxially fixed to each end side of the gear column 7. One end of the driving connecting rod 5 is fixedly connected to the rotating shaft corresponding thereto, and the rotating shafts of the two gear columns 7 located on the inner side are respectively provided with a rotating limiting assembly 8 and a hand wheel 9. The power assembly can be electric or manual, and the hand wheel 9 is preferred. When it is necessary to adjust the bending degree of the reflector 1, the hand wheel 9 is twisted, the hand wheel 9 drives one of the gear columns 7 to rotate, the gear column 7 drives the two gear columns 7 located on the outermost side to rotate, thereby driving the driving connecting rods 5 on both sides to rotate upward synchronously through the rotating shafts connected to the gear columns 7. However, in order to protect the reflector 1 from being damaged due to excessive bending, protrusions can be arranged on the rotating shaft coaxially connected with the hand wheel 9 and the side wall of the shell box body 6. When the hand wheel 9 rotates by a certain angle, the two protrusions will be clamped with each other, thereby preventing the hand wheel 9 from rotating.
[0020] The rotating limiting assembly 8 comprises a ratchet wheel coaxially fixed on the rotating shaft, a push rod is elastically connected to the outer side wall of the shell box body 6, and the end of the push rod is provided with a ratchet tooth matched with the ratchet wheel. The reflective panel 1 and the elastic edge 2 have a tendency to restore the initial state under the action of the elastic potential energy, and the rotating limiting assembly 8 can effectively prevent this tendency. Only when the ratchet tooth is disengaged from the ratchet wheel, the reflective panel 1 and the elastic edge 2 can restore the initial state.
[0021] The position adjusting support mechanism is arranged on the shell box body 6, and comprises a horizontal counterweight base 10, a hollow vertical outer column 11 with an open top is fixed in the middle of the counterweight base 10, an inner column 12 is slidably sleeved on the outer column 11, a plurality of equidiameter limiting bolt holes are arranged in the side walls of the outer column 11 and the inner column 12, a lower platform 13 is horizontally rotatably connected to the top surface of the inner column 12, and a damping member such as a rubber gasket is arranged on the connecting part, so that the rotating position can be fixed at any time. A pair of parallel rotating fixed plates 14 are vertically and fixedly connected to the lower platform 13, a rotating movable plate 15 is arranged between the two rotating fixed plates 14, a horizontal rotating shaft is vertically and fixedly inserted into the lower part of the rotating movable plate 15, the rotating shaft is rotatably and protrudingly arranged on the side walls of the two rotating fixed plates 14, two ratchet wheels are coaxially fixed on the protruding parts of the rotating shaft, ratchet teeth matched with the ratchet wheels are rotatably connected to the side walls of the rotating fixed plates 14 on the same side, and a push rod is fixed on the ratchet teeth. A circular upper platform 16 is fixed to the top of the rotating movable plate 15, a circular rotating block 17 is fixed to the bottom surface of the shell box body 6, and the rotating block 17 is rotatably arranged on the top surface of the upper platform 16. The connecting part is also provided with a damping member.
[0022] In the embodiment, the height of the reflective panel 1 is adjusted by the inner column 12 and the outer column 11 which can be relatively telescopic, and the effect of the universal joint is realized by the upper platform 16, the lower platform 13, the rotating fixed plates 14 and the rotating movable plate 15, so that the reflecting angle of the reflective panel 1 can be adjusted at will, thereby being able to adapt to various light and shadow requirements.
[0023] In use, the counterweight base 10 is placed at a shooting position, the inner column 12 is pulled out upward from the outer column 11, and when the height of the reflective panel 1 is appropriate, the positions of the inner column 12 and the outer column 11 are fixed by bolts through the limiting bolt holes on the inner column 12 and the outer column 11. The rotating angle of the rotating movable plate 15 is adjusted by the two opposite ratchet wheels on the two sides of the rotating fixed plate 14 and the two ratchet teeth matched with the ratchet wheels. When the rotating angle is excessively deviated to one side, the ratchet wheel engaged with one side ratchet tooth is released by pressing the ratchet tooth, and the other side ratchet wheel and the ratchet tooth matched therewith make the rotating movable plate 15 only rotate in the opposite direction.
[0024] Conversely, after the adjustment is completed, the pawl is loosened to keep it fixed to the ratchet, thus completing the rotation of the rotating plate 15 to fix the angle. Further position adjustment of the reflector 1 is achieved by the relative damping rotation between the rotating fixed plate 14 and the lower platform 13 and the upper platform 16 and the rotating block 17. The hand wheel 9 is rotated to gradually bend the reflector 1 to the appropriate angle, and when it is necessary to reduce the bending degree of the reflector 1, the engagement between the ratchet and the ratchet wheel in the rotation limiting assembly 8 is released.
[0025] The embodiment also discloses a use method of the support adjusting assembly, comprising the following steps: Step one: after placing the counterweight base 10 at the shooting position, the inner column 12 is pulled out upward from the outer column 11, and when the height of the reflector 1 is appropriate, the positions of the inner column 12 and the outer column 11 are fixed by using the limiting bolt holes on the inner column 12 and the outer column 11. Step two: the rotation and positioning of the rotating plate 15 are achieved by respectively releasing the engagement between the ratchet and the ratchet wheel on both sides of the rotating fixed plate 14. Step three: further position adjustment of the reflector 1 is achieved by the relative damping rotation between the rotating fixed plate 14 and the lower platform 13 and the upper platform 16 and the rotating block 17. Step four: the hand wheel 9 is rotated to gradually bend the reflector 1 to the appropriate angle, and when it is necessary to reduce the bending degree of the reflector 1, the engagement between the ratchet and the ratchet wheel in the rotation limiting assembly 8 is released.
