Detailed Description of the Preferred Embodiment

[0026] To further understand the features, technical means, specific purposes and functions achieved by the present utility model, the following further detailed description of the present utility model will be given in conjunction with the drawings and specific embodiments.

[0027] See Figures 1-4As shown in the figure, a photography flash filter assembly that is easy to adjust includes a lamp shade 2 threadedly installed at the light irradiation position of the photography flash main body 1, and an adjustment mechanism 3 rotatably arranged on the lamp shade 2 for filtering and adjusting the light irradiated from the photography flash main body 1. It is characterized in that the adjustment mechanism 3 includes a filter placement plate 31 and a filter plate 32 detachably arranged in the filter placement plate 31, and a fixing and adjusting mechanism 4 for driving the filter placement plate 31 to rotate and then fix the angle. There are a pair of filter placement plates 31.

[0028] When it is necessary to change the filtering of the light of the photography flash main body 1, first, through the adjustment mechanism, the filter placement plate 31 is rotated, and then the positions of the filter placement plate 31 and the filter plate 32 can be adjusted to adapt to the changes in the light of the photography flash main body 1 in different scenarios. And the position of the rotated filter placement plate 31 can be fixed by the subsequent fixing and adjusting mechanism 4 to prevent the filter placement plate 31 from rotating freely and affecting the use effect of the photography flash main body 1.

[0029] See Figure 3 and Figure 4 As shown in the figure, the adjustment mechanism 3 further includes a circular limiting groove 33 and a placement groove 34. The circular limiting groove 33 is opened on the lamp shade 2, and the circular limiting groove 33 is used to limit the rotational movement of the filter placement plate 31. The placement groove 34 is opened on the filter placement plate 31, and the placement groove 34 is used to limit the quick installation of the filter plate 32 into the filter placement plate 31.

[0030] When the position of the filter placement plate 31 needs to be rotationally adjusted, the filter placement plate 31 can swing stably along the circular limiting groove 33 opened on the lamp shade 2. After the filter placement plate 31 disengages from the circular limiting groove 33, different colored filter plates 32 are quickly installed into the filter placement plate 31 through the placement groove 34. Then the filter plate 32 can be quickly installed into the filter placement plate 31. After the installation is completed, the filter placement plate 31 continues to rotate until the second filter placement plate 31 rotates to the circular limiting groove 33. At this time, the quick change of different filter colors for the photography flash main body is completed.

[0031] See Figures 3-5 As shown in the figure, the fixing and adjusting mechanism 4 includes a rotating rod 41, a fixing block 42, a sliding rod 43, and a clamping block 44. The rotating rod 41 is rotatably arranged on the lamp shade 2, and the rotating rod 41 is fixedly connected to the filter placement plate 31. The fixing block 42 is arranged on the lamp shade 2 and is located above the rotating rod 41. The sliding rod 43 is slidably arranged vertically on the fixing block 42 and is located above the rotating rod 41. The clamping block 44 is arranged on the sliding rod 43 and is used to clamp and fix the rotating rod 41.

[0032] When it is necessary to fix the position of the rotated filter placement plate 31, first, when rotating the filter placement plate 31, rotate the rotating rod 41 first, and at the same time move the sliding rod 43 and the clamping block 44 upward in the vertical direction until the clamping block 44 disengages from the outside of the rotating rod 41. At this time, the rotating rod 41 and the filter placement plate 31 can be rotated. After the user finishes rotating, release the sliding rod 43. At this time, the sliding rod 43 can drive the clamping block 44 to move upward in the vertical direction until the clamping block 44 disengages from the outside of the rotating rod 41, thereby fixing the rotation angle of the rotating rod 41 and preventing the filter placement plate 31 from rotating freely.

[0033] See Figure 5 As shown, the fixing and adjusting mechanism 4 further includes a clamping groove 45 and a return spring 46; a plurality of clamping grooves 45 are formed on the rotating rod 41, and the clamping grooves 45 are used for clamping with the clamping block 44; the return spring 46 is arranged on the sliding rod 43, and both ends of the return spring 46 are fixedly connected to the sliding rod 43 and the end of the fixed block 42 respectively.

[0034] In the initial state, the elastic force of the return spring 46 can drive the sliding rod 43 and the clamping block 44 to always contact and engage with the clamping groove 45 formed on the rotating block. When the sliding rod 43 and the clamping block 44 move upward in the vertical direction, the return spring 46 can be compressed. When the sliding rod 43 is released, the return spring 46 is released, causing the sliding rod 43 and the clamping block 44 to move downward in the vertical direction, thereby fixing the positions of the clamping groove 45 and the rotating rod 41 and effectively preventing the free rotation of the rotating rod 41.

[0035] See Figures 4-6 As shown, the photography flash filter assembly that is convenient to adjust further includes a protection mechanism 5 arranged on the lamp cover 2 for shielding and protecting the idle photography flash main body 1; the protection mechanism 5 includes a shielding protection plate 51, a rotating rod 52, and a receiving block 53; the shielding protection plate 51 is rotatably arranged on the lamp cover 2; the rotating rod 52 is rotatably arranged on the lamp cover 2, and the rotating rod 52 is fixedly connected to the shielding protection plate 51; the receiving block 53 is arranged on the lamp cover 2 and is used for limiting and storing and fixing the shielding protection plate 51.

[0036] When the photography flash main body 1 is not in use and is idle, first rotate the rotating rod 52 and the shielding protection plate 51 until the shielding protection plate 51 is in front of the lamp cover 2. At this time, the lamp cover 2 can be shielded and protected. After the shielding protection plate 51 rotates and shields, it can be located in the receiving block 53 and will stop rotating when it rotates to contact the receiving block 53, achieving the shielding protection of the lamp cover 2 and the photography flash main body 1 when not in use and idle, and extending the service life of the lamp cover 2 and the photography flash main body 1.

[0037] See Figures 4-6As shown, the protection mechanism 5 further includes a mounting block 54, a threaded rod 55, a threaded sliding block 56, and a limiting groove 57; the mounting block 54 is provided on the lamp cover 2 and is close to one side of the rotating rod 52; the threaded rod 55 is threadedly mounted on the mounting block 54 in the horizontal linear direction; the threaded sliding block 56 is slidably arranged on the mounting block 54 in the horizontal linear direction, and the threaded sliding block 56 is connected to the threaded rod 55 by a bearing; the limiting groove 57 is formed on the rotating rod 52, and the limiting groove 57 is used to contact the threaded sliding block 56 to prevent the rotating rod 52 from freely rotating.

[0038] When it is necessary to rotate and open the shielding protection plate 51 for the normal use of the photographic flash main body 1, first, the shielding protection plate 51 is driven to rotate by the rotating rod 41 until the shielding protection plate 51 disengages from the receiving block 53 and approaches the mounting block 54. At this time, the threaded rod 55 is rotated, and then the threaded rod 55 can slide the threadedly connected threaded sliding block 56 in the horizontal linear direction. Then, the threaded sliding block 56 can slide in the horizontal linear direction under the rotational force of the threaded rod 55 to a position close to the limiting groove 57 formed on the rotating rod 52 until the threaded sliding block 56 contacts the limiting groove 57 and fixes the rotating rod 52. Thus, the position of the opened shielding protection plate 51 can be fixed, achieving the storage and shielding of the shielding protection plate 51 during use.
