Description

Technical Field

[0001] The utility model belongs to the technical field of shooting equipment, and in particular relates to a fill light stand. Background Art

[0002] In the process of film and television shooting, fill light is an indispensable auxiliary equipment, which can provide a brighter and more uniform lighting environment for the shooting scene, help improve the shooting quality to adapt to different shooting scenes.

[0003] Most of the light stands in the prior art are of tripod type, which need to be adjusted by human height without assistance. If the light fixture mounted on the tripod is heavy, it is easy to cause the operator's palm to be caught in the gap between the two telescopic tubes by surprise, causing personal injury. In addition, the conventional tripod light fixture can only be mounted in the middle of the tripod. Since there is no horizontal extension rod parallel to the ground, the mounted shooting light fixture cannot cross the top of the object, thereby affecting the photographer's arrangement of the light.

[0004] In order to provide a better lighting environment, some fill light stands on the market currently have a liftable function, which can provide better lighting for the required scene. However, the liftable mechanism of the fill light stand in the prior art is usually implemented by a screw slider mechanism. During the lifting process, the screw slider mechanism will produce a downward displacement due to its own weight and the weight of the fill light, resulting in failure of height adjustment. For example, in the utility model patent "A fill light for film and television shooting" with the authorization announcement number CN221237812U, the height of the fill light is adjusted by a linear screw module, a drive motor, a slider, etc. On the one hand, the use of the drive motor increases the weight of the equipment. On the other hand, because the linear screw module is installed in the vertical direction, the slider is easily displaced downward due to the action of gravity, resulting in the inability to accurately adjust the height.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figures 1 to 9 As shown, the utility model provides a fill light stand, comprising a base 1, a fixed rod 2, a telescopic rod 3, and a lifting mechanism, wherein the fixed rod 2 is fixedly mounted on the base 1, the fixed rod 2 is a hollow structure with an opening at the top, and the telescopic rod 3 is telescopically mounted inside the fixed rod 2 through the lifting mechanism;

[0038] The lifting mechanism includes a housing 15 and a worm gear mechanism rotatably mounted inside the housing 15. The housing 15 is fixedly mounted on the fixed rod 2. A rack 4 is fixedly mounted on the telescopic rod 3. The rack 4 is meshingly connected with the worm gear mechanism.

[0039] Specifically, in a specific embodiment, the worm gear mechanism includes a worm 5, a first worm wheel 6 and a second worm wheel 7. The first worm wheel 6 and the second worm wheel 7 are rotatably installed in the interior of the housing 15 through bearings and connecting rods, respectively. The first worm wheel 6 is located between the worm 5 and the second worm wheel 7 and is meshingly connected to the two respectively. The second worm wheel 7 is meshingly connected to the rack 4. A handle 8 is fixedly installed on the worm 5. The handle 8 is a lifting rocker handle. A through hole is provided on the housing 15, and the handle 8 extends to the outside of the housing 15 through the through hole.

[0040] In other preferred embodiments, the worm gear mechanism includes a worm 5 and a first worm wheel 6; the first worm wheel 6 is rotatably mounted inside the housing 15 via a bearing and a connecting rod, and one side of the first worm wheel 6 is meshingly connected to the worm 5, and the other side is meshingly connected to the rack 4; a handle 8 is fixedly mounted on the worm 5, and a through hole is provided on the housing 15, and the handle 8 extends through the through hole to the outside of the housing 15.

[0041] A light mounting frame 9 is mounted on one end of the telescopic rod 3 away from the fixed rod 2 , and a fill light can be mounted on the light mounting frame 9 .

[0042] Specifically, a rotating mechanism is provided between the telescopic rod 3 and the lamp mounting frame 9, and the rotating mechanism includes a first rotating rod 10 and a second rotating rod 11 arranged in parallel, and the first rotating rod 10 and the second rotating rod 11 are respectively installed on the telescopic rod 3 and the lamp mounting frame 9 through a rotating axis and parallel rotation.

[0043] The line segment formed between the rotation connection point between the telescopic rod 3 and the first rotating rod 10, and the rotation connection point between the telescopic rod 3 and the second rotating rod 11, is parallel to the line segment formed between the rotation connection point between the lamp mounting frame 9 and the first rotating rod 10, and the rotation connection point between the lamp mounting frame 9 and the second rotating rod 11. That is, the area between the first rotating rod 10, the second rotating rod 11, the rotation connection point between the telescopic rod 3 and the first rotating rod 10, and the rotation connection point between the telescopic rod 3 and the second rotating rod 11, and the area between the rotation connection point between the lamp mounting frame 9 and the first rotating rod 10, and the rotation connection point between the lamp mounting frame 9 and the second rotating rod 11 together form a parallelogram structure. By adjusting the angle of the parallelogram, the angle between the rotating mechanism and the telescopic rod 3 can be adjusted, and then the angle of the lamp mounting frame 9 can be adjusted; and the parallelogram structure can also make the end face height of the lamp mounting frame 9 always remain parallel to the ground, ensuring that the fill light installed on the lamp mounting frame 9 can only be raised and lowered in the vertical height without position deviation in other directions.

[0044] At the same time, in order to make the rotation speed of the rotating mechanism uniform, a damping rod 12 is rotatably installed between the first rotating rod 10 and the second rotating rod 11. The setting of the damping rod 12 can also improve the safety of the equipment. When the front section is loaded, if the locking bolt 16 is loosened rashly, the front end of the second rotating rod 11 will suddenly fall down and the rear end will suddenly rise up, which may hit the operator. After adding the damping rod 12, this process will be delayed, so that the operator has time to react and dodge.

[0045] In order to accurately measure and lock the rotation angle, an angle plate 13 is provided at the position where the second rotating rod 11 is connected to the telescopic rod 3, a slide groove 14 is provided in the angle plate 13, a mounting hole is provided on the second rotating rod 11, and a locking bolt 16 is provided through the slide groove 14 and the mounting hole.

[0046] In addition, a hook 17 for hanging a counterweight is fixedly mounted on the end of the second rotating rod 11 located on one side of the telescopic rod 3 .

[0047] In order to make the structure of the base 1 more stable, a reinforcing rib plate 18 is provided at the connection between the base 1 and the fixing rod 2 .

[0048] A storage platform 19 is fixedly mounted on the base 1 and can be used to place photographic equipment or items. Universal wheels can also be installed below the base 1 to facilitate the movement of the fill light stand.

[0049] When the fill light stand of the utility model is used, the angle of the light mounting frame 9 relative to the telescopic rod 3 is first adjusted by the rotating mechanism, and then the height of the telescopic rod 3 is adjusted by the lifting mechanism, so as to ensure that the fill light is located at the most appropriate position for easy shooting.

[0050] Specifically, the angle adjustment process is as follows:

[0051] Hang a suitable counterweight on the hook 17 (it can be a special counterweight or other heavy items, such as a backpack or shooting equipment not needed on site), loosen the locking bolt 16, turn the light mounting bracket 9, adjust the angle between the rotating mechanism and the telescopic rod 3, rotate to a suitable angle, and tighten the locking bolt 16 to fix the angle.

[0052] The process of the lifting mechanism adjusting the height of the telescopic rod 3 is as follows:

[0053] The handle 8 is turned, and the handle 8 drives the worm 5, the first worm gear 6 and the second worm gear 7 to rotate in sequence, and then drives the rack 4 to move in the vertical direction, so that the height of the telescopic rod 3 can be adjusted. The rotary motion is converted into the vertical motion of the telescopic rod 3 by the worm gear mechanism. After the height is adjusted appropriately, the handle 8 is released. Due to the characteristics of the worm gear movement, once the worm 5 stops rotating, the movement of the telescopic rod 3 also stops, and the telescopic rod 3 will not move in the height direction again. The height control process is accurate and stable.
