[0039] Please refer to Figure 1-Figure 3 , this embodiment provides a photographic rocker arm, which includes a frame, a shooting rocker arm, photographic equipment and a sliding rotator 100;

[0040] The shooting rocker arm is movably connected to the frame; the sliding rotator 100 includes a connecting arm 110, a sliding bar 120, a slider 130 and a connecting rod 140; one end of the connecting arm 110 is connected to the sliding bar 120, and the other end of the connecting arm 110 is rotatably connected to the shooting rocker arm; the slider 130 is slidably connected to the sliding bar 120 along the extension direction of the sliding bar 120, and the slider 130 is connected to the photographic equipment; the connecting rod 140 is connected to the sliding bar 120, and is used to install a counterweight.

[0041] Please refer to Figure 1-Figure 3 , the working principle of the photography rocker arm is:

[0042] The sliding rotator 100 in the photographic rocker arm includes a connecting arm 110, a sliding rod 120, a slider 130 and a connecting rod 140; wherein, one end of the connecting arm 110 is connected to the sliding rod 120, and the other end of the connecting arm 110 is used to be rotatably connected to the photographic rocker arm; the slider 130 is slidably connected to the sliding rod 120 along the extension direction of the sliding rod 120, and the slider 130 is used to be connected to the photographic equipment; the connecting rod 140 is connected to the sliding rod 120, and is used to install a counterweight.

[0043] Therefore, during use, the spatial position of the photographic equipment can be adjusted by the rotation of the connecting arm 110 relative to the shooting rocker arm and the sliding of the slider 130 relative to the slide bar 120, thereby adjusting the shooting angle of the photographic equipment to meet the shooting requirements of different scenes. At the same time, the shooting range of the photographic equipment can be expanded by coordinating the movement of the shooting rocker arm relative to the frame.

[0044] Furthermore, since the connecting rod 140 for installing the counterweight is connected to the slide bar 120, the stability of the photographic equipment connected to the slide bar 130 during the movement can be improved by installing the counterweight, thereby improving the shooting quality.

[0045] In addition, by adopting the above-mentioned sliding rotator 100, the photographic crane arm can realize the rotation and sliding of the photographic equipment relative to the photographic crane arm with a simple structure, thereby reducing the operating difficulty while effectively reducing the use cost of the photographic crane arm and meeting the shooting needs of different scenes of the photographic crane arm.

[0046] For further information, please refer to Figure 1-Figure 3 In this embodiment, in order to enable the slider 130 to slide relative to the slide bar 120, a variety of structural settings are provided, such as providing a slideway 122 or sleeve the slider 130 on the slide bar 120;

[0047] In the present embodiment, in order to prevent the slider 130 from interfering with the connecting arm 110 in movement during the sliding process relative to the slide bar 120, a mounting platform 121 and a slideway 122 are provided on the slide bar 120. The mounting platform 121 and the slideway 122 are located on opposite sides of the slide bar 120, and the slideway 122 is arranged along the extension direction of the slide bar 120; wherein the connecting arm 110 is connected to the mounting platform 121, and the slider 130 and the slideway 122 are slidably matched.

[0048] Based on this, in order to improve the stability of the slider 130 during the sliding process, the slide 122 is T-shaped; when setting the slider 130, the slider 130 can include a sliding part 131 that slides with the slide 122 and a connecting part 132 that is connected to the photographic equipment; wherein the sliding part 131 is located inside the slide 122, and the connecting part 132 is located outside the slide 122.

[0049] In this way, the sliding part 131 can slide relative to the slideway 122, thereby driving the photographic equipment connected to the connecting part 132 to slide relative to the slide rod 120. Such a structural setting can not only improve the stability of the photographic equipment during the sliding adjustment process, but also simplify the setting of the sliding structure and reduce the cost of production and use.

[0050] Please refer to Figure 1-Figure 3In this embodiment, in order to increase the types of photographic equipment that the sliding rotator 100 can adapt to, the sliding rotator 100 can also include an expansion connection platform 150, which is detachably connected to the slider 130, and the expansion connection platform 150 is used to connect with the photographic equipment. In order to enable the expansion connection platform 150 to dock with different types of photographic equipment to increase its scope of use and thereby reduce the cost of use, a plurality of reserved mounting holes can be provided on the expansion connection platform 150 to meet the connection requirements of a variety of photographic equipment. It should be noted that a plurality of expansion connection platforms 150 can also be provided, each of which corresponds to docking with one or more types of photographic equipment; in addition, when the connection portion 132 of the slider 130 can meet the docking requirements of the photographic equipment, the expansion connection platform 150 can also be removed from the connection portion 132, thereby simplifying the structure of the photographic rocker arm.

[0051] When installing the counterweight, the present embodiment adopts a method of installing the counterweight on the connecting rod 140 . To prevent the counterweight from interfering with the sliding of the photographic equipment relative to the slide bar 120 , the connecting rod 140 and the mounting platform 121 are located on the same side of the slide bar 120 .

[0052] For further information, please refer to Figure 1-Figure 5 In this embodiment, when the slider 130 slides relative to the slideway 122 under the driving action of the driving member, in order to prevent it from sliding out of the slideway 122 from both ends of the slideway 122, the two ends of the slideway 122 are detachably connected to the limit blocks 160 along the extension direction of the slide bar 120, and the limit blocks 160 are used to limit the movement of the slider 130 in the direction of sliding out of the slideway 122. It should be noted that such a structural setting is because the present embodiment adopts a structural setting that opens both ends of the slideway 122 to facilitate the installation of the slider 130, and in other embodiments of the present utility model, one end of the slideway 122 can be opened and the other end is blocked, and then the above-mentioned limit block 160 is set at its open end.

[0053] For details, please refer to Figure 1-Figure 5 , the limit block 160 in this embodiment may include a movable portion 161, a locking rod 162, a locking portion 163 and a locking member 164;

[0054] The movable part 161 is slidably matched with the slideway 122; the locking rod 162 is connected with the movable part 161, and the locking part 163 is slidably connected with the locking rod 162, and the locking part 163 is located outside the slideway 122; the locking member 164 is threadedly connected with the locking rod 162, and is used to drive the locking part 163 to move in the direction of abutting against the slide bar 120. Therefore, during use, the locking member 164 can be rotated to abut against the locking part 163, and the locking member 164 is continuously rotated until the locking part 163 is pressed against the slide bar 120, thereby, the slider 130 can be abutted by one or both of the locking part 163 and the movable part 161, thereby limiting the movement of the slider 130 in the direction of sliding out of the slideway 122. When the locking rod 162 is set, the present embodiment adopts a setting mode in which the locking rod 162 extends in a direction perpendicular to the slide bar 120. It should also be noted that, through the structural setting of the above-mentioned limit block 160, the locking part 163 can be disengaged from the abutment with the slide bar 120 by rotating the locking piece 164, thereby driving the limit block 160 to slide relative to the slideway 122 of the slide bar 120. After adjusting to a suitable position, the locking piece 164 is rotated to make the locking part 163 press the slide bar 120, so that the maximum sliding stroke of the slider 130 relative to the slideway 122 can be adjusted in this way.

[0055] In other embodiments of the present invention, please refer to Figure 1-Figure 6 , a plurality of limiting holes may be provided at intervals along the extending direction of the slide bar 120; the sliding rotator 100 further includes a limiting rod 170, which is threadedly connected to one of the limiting holes, and at least a portion of the limiting rod 170 is located in the slideway 122. Thus, the portion of the limiting rod 170 located in the slideway 122 abuts against the sliding portion 131 of the slider 130, thereby limiting its sliding, and further limiting the movement of the slider 130 in the direction of sliding out of the slideway 122; and in this way, the maximum sliding stroke of the slider 130 relative to the slideway 122 can be adjusted by adjusting the limiting rod 170 to cooperate with different limiting holes.

[0056] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
