Description

Technical Field

[0001] This utility model belongs to the field of photographic equipment technology, and in particular relates to a softbox. Background Technology

[0002] A softbox is an accessory for studio lights. By being mounted on a studio light, it makes the emitted light softer and can eliminate glare and shadows in photos during shooting. It is mainly used in video micro-films, online live broadcasts, and film and television shooting.

[0003] Patent CN202022900347.5 discloses a softbox that uses color-changing cloths for color adjustment. It includes a softbox cloth, a frame, a photographic light, and one or both of two color-changing cloths: a first color-changing cloth and a second color-changing cloth. The softbox cloth covers the frame, which has a flared opening. The photographic light is fixed in the middle of the frame. The first color-changing cloth fits into the opening of the softbox cloth, and the second color-changing cloth fits into the middle of the frame. This application allows for full-coverage color-changing with a large color-changing cloth or partial-coverage color-changing with a small color-changing cloth through simple connections, thus solving the problem of inconvenient color-changing, providing more color-changing effects, and improving photographic efficiency and quality.

[0004] In the aforementioned patent, the camera light is fixed to the end of the support rod, making it impossible to adjust the angle of the softbox. Utility Model Content

[0035] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0036] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] like Figure 1-5As shown, a softbox includes a photography light 1, a frame 2, a softbox cloth 3, a support rod 4, and an adjustment mechanism. The frame 2 is evenly arranged around the photography light 1, and one end of it is connected to the outer shell of the photography light 1. The softbox cloth 3 is covered and fixed on the frame 2. The support rod 4 is connected to the photography light 1 through the adjustment mechanism.

[0038] Specifically, the adjustment mechanism includes a fixed base 51, a connecting base 52, a rotating shaft 53, a worm gear 54, a handle 56, and a worm 55. The fixed base 51 is fixed to the housing of the photographic lamp 1; the connecting base 52 is fixed to the end of the support rod 4; the rotating shaft 53 is fixed to the fixed base 51, and both ends of the rotating shaft 53 are rotatably connected to the connecting base 52; the worm 55 is rotatably connected to the connecting base 52; the worm gear 54 is fixed to the connecting base 52, and its axis coincides with the axis of the rotating shaft 53. The worm gear 54 meshes with the worm 55, and the worm gear 55... The transmission ratio of 5 is designed to be 20:1. The lead angle of worm 55 is less than the equivalent friction angle between the teeth of worm wheel 54. Therefore, by rotating worm 55, worm wheel 54 can be driven to rotate, which in turn drives the camera lamp 1 to rotate relative to the rotating shaft 53, thereby realizing angle adjustment. Moreover, by utilizing the self-locking characteristics of worm wheel 54 and worm 55 (only worm 55 drives worm wheel 54, and it cannot be driven in the opposite direction), the angle is automatically locked after adjustment, without the need for an additional locking device. The handle 56 is fixed to the end of worm 55, which improves the convenience of operation, and the user can complete the angle adjustment with one hand.

[0039] As a preferred embodiment, the worm gear 54 is a semi-circular ring with both ends fixed to the bottom of the connecting seat 52. Limiting plates 57 are fixed at both ends of the worm gear 54, and connecting plates 58 are symmetrically provided on the connecting seat 52. The worm 55 is rotatably connected to the connecting plate 58. When the end of the worm gear 54 rotates to contact the worm 55, the connecting plate 58 can contact the limiting plate 57 to limit the angle adjustment range and avoid excessive rotation that could cause structural damage.

[0040] In other embodiments, the frame 2 is detachably provided with a soft light grid 61, and the end of the frame 2 is fixedly provided with a mounting plate 62. A first magnetic strip 63 is fixedly provided on the mounting plate 62, and a second magnetic strip 64 is fixedly provided on the soft light grid 61. Both the first magnetic strip 63 and the second magnetic strip 64 are neodymium iron boron strong magnetic strips. The soft light grid 61 is detachably designed to expand its functions and adapt to different light control needs.

[0041] In other embodiments, the support rod 4 is provided with a height adjustment assembly, which includes an adjustment tube 71, a mounting hole 72, an elastic element 73, a top rod 74, a ball bearing 75, a limiting protrusion 76, a base plate 77, a silicone pad 78, an auxiliary support foot 79, and a support plate 70. The adjustment tube 71 allows the support rod 4 to be inserted and slide up and down. The mounting hole 72 is formed on the support rod 4. The elastic element 73 is a spring, one end of which is fixed in the mounting hole 72. One end of the top rod 74 is fixed to the end of the spring and can slide relative to the inner wall of the mounting hole 72. The ball bearing 75 is rotatably connected to the end of the top rod 74. The adjustment tube 71 is evenly provided with a plurality of locking holes 711, which allow the ball bearing 75 to slide up and down. When ball 75 is inserted, the ball 75 will be squeezed and moved out of the locking hole 711 when the support rod 4 is moved up and down. After the height adjustment is completed, the elastic element 73 will push the ball 75 into the locking hole 711, thereby locking the support rod 4. The limiting protrusion 76 is fixed on the outer wall of the support rod 4. The inner wall of the adjusting tube 71 is provided with a limiting groove that cooperates with the limiting protrusion 76 to prevent the support rod 4 from rotating relative to the adjusting tube. The base plate 77 is fixed on the end of the adjusting tube. The silicone pad 78 is fixed on the bottom surface of the base plate 77. The auxiliary support foot 79 is evenly arranged around the adjusting tube 71, and one end of it is rotatably connected to the adjusting tube 71. The support plate 70 is fixed on the end of the auxiliary support foot 79.

[0042] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
