Description

Technical Field

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

[0002] Film and television photography and production is what we commonly refer to as the filming and production process for films, television programs, or animations. Pre-production includes the actors' performances, set design, prop production, and lighting. This stage is crucial, as it determines the visual style and atmosphere of the work. Pre-production also provides the basis and material preparation for post-production.

[0003] In the prior art, a search of Chinese patent number CN202322003083.7 discloses a light-blocking device for film and television shooting, comprising a storage box, a cavity being opened in the storage box, a fixed shaft being fixedly connected in the cavity, a light-blocking cloth being connected to the surface of the fixed shaft through a coil spring, the other end of the light-blocking cloth slidingly passing through the cavity, and a cross bar being fixedly connected to the end portion, the storage box being in a "U" shape, and both short arm ends of the storage box being hingedly connected to columns.

[0004] When filming movies and TV shows, in order to reflect good image light and texture, it is necessary to block or fill in the light of the scene being filmed due to the influence of the surrounding environment. However, the visors currently used in the shooting process need to be manually held to block the light. In the above solution, the light-blocking cloth can be retracted by retracting the vertical pole through a hinge. When used, it not only increases the labor intensity but also makes it difficult to flexibly adjust the light-blocking angle, thereby increasing the tediousness of the light-blocking work during film and TV shooting.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0028] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 2 、 Figure 5As shown, the utility model is a light blocking device for shooting, comprising a support tube 1, a lifting assembly 2 is arranged inside the support tube 1, a fixed sleeve 3 is sleeved on the outer surface of the support tube 1, and the outer surface of the fixed sleeve 3 is fixedly connected to a fixed plate 4, the inner wall of the fixed plate 4 is threadedly connected to a screw 5, the outer surface of the screw 5 is threadedly connected to a threaded sleeve 6, and one side of the threaded sleeve 6 is fixedly connected to a sleeve 7, the sleeve 7 passes through and is slidably connected to the outer surface of the lifting assembly 2, a support assembly 8 is arranged on one side of the sleeve 7, and a light blocking assembly 9 is arranged at one end of the support assembly 8, vertical grooves 10 are symmetrically opened on the outer surface of the support tube 1, the internal thread of the lifting assembly 2 is threadedly connected to a driving mechanism 11, and the interior of the lifting assembly 2 is symmetrically provided with a telescopic limit assembly 12.

[0031] When in use, the screw 5 is supported on one side of the support tube 1 by the cooperation of the fixed sleeve 3 and the fixed plate 4. When the light blocking component 9 needs to be supported in the light blocking position, the lowering component 2 is lifted to move along the inner side of the support tube 1, thereby driving the fixed sleeve 3 and the sleeve 7 to move together. When the lifting component 2 rises to a fixed height, the driving mechanism 11 is rotated to push the telescopic limit components 12 on both sides from the inner side of the lifting component 2 to extend toward the inner wall of the support tube 1 and press against its inner wall, thereby limiting the lifting component 2 from continuing to move. At this time, the fixed The position of the fixed sleeve 3 is limited together, and the screw 5 is rotated to drive the threaded sleeve 6 to move outside it to drive the sleeve 7 to move synchronously on the outside of the lifting assembly 2, thereby driving the support assembly 8 and the light blocking assembly 9 to move together, so that the light blocking assembly 9 is displaced alone to change its light blocking height. When use is completed, the reverse drive mechanism 11 releases the restriction on the telescopic limit assembly 12 so that the lifting assembly 2 can be lowered and recovered inside the support tube 1 to reduce its support height, so as to reduce the support height of the light blocking assembly 9.

[0032] The utility model connects the sleeve 7 with the lifting component 2, and cooperates with the fixed sleeve 3 to support the screw 5 on one side of the lifting component 2. When the lifting component 2 is fully extended to the outside of the support tube 1, the threaded sleeve 6 is driven to move by rotating the screw 5 to cooperate with the sleeve 7 to move outside the lifting component 2 and simultaneously drive the supporting component 8 and the light blocking component 9 to move, so that the height of the light blocking component 9 can be adjusted separately on the outside of the lifting component 2, and when the lifting component 2 is lifted and lowered inside the support tube 1, it can synchronously drive the fixed sleeve 3 and the light blocking component 9 to be lifted and lowered as a whole and cooperate with the telescopic limit component 12 to limit it to any position of the support tube 1, so that the light blocking component 9 can be flexibly adjusted when in use to reduce the labor intensity of manual operation, and when not in use, the height of the light blocking component 9 can be folded for easy storage in conjunction with the recovery of the lifting component 2.

[0033] In one embodiment, for the above-mentioned lifting assembly 2, the lifting assembly 2 includes a lifting rod 201, the bottom of the lifting rod 201 is fixedly connected to a telescopic rod 202, the bottom of the telescopic rod 202 extends to the interior of the support tube 1 and is fixedly connected thereto, the top of the lifting rod 201 is fixedly connected to a top plate 203, and the top end of the screw 5 passes through the top of the top plate 203 and is rotatably connected thereto.

[0034] The telescopic rod 202 is supported inside the central groove inside the support tube 1. When the lifting rod 201 is lifted or pushed, the extension and retraction of the telescopic rod 202 drive the lifting rod 201 to move up and down. When the lifting rod 201 is lifted or down, the screw 5 is in a stationary state so that after the lifting rod 201 is lifted or down, the sleeve 7 outside the lifting rod 201 is still at the initial position of the lifting rod 201, so that after the lifting rod 201 is fully extended, the height of the light blocking component 9 is only driven and adjusted by the screw 5, and by cooperating with the top plate 203, it can provide top auxiliary support for the screw 5.

[0035] In one embodiment, for the above-mentioned support assembly 8 , the support assembly 8 includes a T-shaped plate 801 , both ends of the T-shaped plate 801 are fixedly connected to a connecting plate 802 , and the connecting plate 802 is fixedly connected to the light blocking assembly 9 .

[0036] One end of the T-shaped plate 801 is connected to the sleeve 7. When the sleeve 7 is driven by the threaded sleeve 6 to slide on the outside of the lifting rod 201, the T-shaped plate 801 is driven to move together with the connected light-blocking component 9. In this way, the driving screw 5 cooperates with the threaded sleeve 6 and the sleeve 7 to provide driving force for the height adjustment of the light-blocking component 9, so that the light-blocking component 9 can be supported at any height of the extension section of the lifting rod 201.

[0037] By setting connecting plates 802 at both ends of the T-shaped plate 801, the upper and lower ends can provide balanced connection support for the light blocking component 9. At the same time, after the screw 5 drives the threaded sleeve 6 to drive the sleeve 7 to move, the T-shaped plate 801 drives the light blocking component 9 to move together, so that the light blocking component 9 can be adjusted to any height for the shooting scene to block light at different positions.

[0038] In one embodiment, for the above-mentioned light blocking assembly 9, the light blocking assembly 9 includes a center baffle 901, and side baffles 902 are rotatably installed on both sides of the center baffle 901, and the top and bottom of the center baffle 901 are rotatably connected to auxiliary baffles 903, and the connecting plate 802 is fixedly connected to the back of the center baffle 901.

[0039] By arranging side baffles 902 on both sides of the central baffle 901 to cooperate with the auxiliary baffle 903, the side baffles 902 and the auxiliary baffle 903 can be flipped over when needed to increase the light blocking range around the central baffle 901. When not needed, the side baffles 902 and the auxiliary baffle 903 can be folded inward to reduce the blocking range outside the central baffle 901. In this way, when blocking light in the on-site shooting scene, the light blocking range can be adjusted according to the light blocking needs.

[0040] In one embodiment, for the above-mentioned driving mechanism 11, the driving mechanism 11 includes a threaded rotating rod 1101, which passes through the fixed sleeve 3 and extends to the interior of the lifting rod 201. One end of the threaded rotating rod 1101 is fixedly connected to an arc-shaped top block 1102, and an internal through hole 204 is opened inside the lifting rod 201.

[0041] The threaded rotating rod 1101 passes through the fixed sleeve 3 and extends along the inner side of the vertical groove 10 to the inside of the lifting rod 201. When the threaded rotating rod 1101 is rotated, the arc surface of the arc-shaped top block 1102 at its end is rotated to the horizontal direction, and the central space inside the inner through hole 204 is reduced. The two sides of the arc-shaped top block 1102 squeeze the telescopic limit assembly 12 to form a driving force, pushing it to extend toward the inner wall of the support tube 1 and press against the inner wall. When rotated in the opposite direction, the horizontal surface of the arc-shaped top block 1102 flips to its original position to release the top pressure on the telescopic limit assembly 12, so that the telescopic limit assembly 12 is reset and the lifting rod 201 is released from the restricted state.

[0042] By passing the threaded rotating rod 1101 through the fixed sleeve 3 and cooperating with the vertical groove 10 so that its end extends to the inside of the lifting rod 201 and is connected to the arc-shaped top block 1102, when the threaded rotating rod 1101 drives the telescopic limit assembly 12 to limit the position of the lifting rod 201, the position of the fixed sleeve 3 is locked together, so that the positions of the fixed sleeve 3 and the lifting rod 201 on the inside and outside of the support tube 1 are always consistent, and the setting of the vertical groove 10 makes the moving paths of the threaded sleeve 6 and the T-plate 801 unrestricted when they are lifted together, thereby making the fixing and loosening operations of the lifting rod 201 and the fixed sleeve 3 more convenient.

[0043] In one embodiment, for the above-mentioned telescopic limit assembly 12, the telescopic limit assembly 12 includes a conical column 1201, one end of the conical column 1201 is fixedly connected to a spring 1202, one end of the spring 1202 is fixedly connected to an inner top block 1203, and the conical column 1201 is located inside the inner through hole 204.

[0044] The conical column 1201 is located inside the lifting rod 201 and is close to the end face of the arc-shaped top block 1102. When the arc-shaped top block 1102 is driven to rotate, its arc surface rotates and contacts the top surface of the conical column 1201, thereby forming a driving force on the conical column 1201 to compress the spring 1202 outward and push the inner top block 1203 to be squeezed against the inner wall of the support tube 1. When the arc-shaped top block 1102 rotates in the opposite direction, its horizontal surface is reset and the squeezing of the conical column 1201 is released at the same time, so that the spring 1202 drives the inner top block 1203 to rebound and reset, so that the lifting rod 201 can be quickly fixed and loosened.

[0045] In one embodiment, for the above-mentioned support tube 1, a load-bearing seat 13 is fixedly connected to the bottom of the support tube 1, a bottom groove 14 is opened at the bottom of the load-bearing seat 13, and a bottom wheel 15 is rotatably installed on the inner wall of the bottom groove 14.

[0046] By opening a bottom groove 14 at the bottom of the load-bearing seat 13, a part of the bottom wheel 15 can be hidden inside the bottom groove 14. At the same time, the setting of the bottom wheel 15 can provide a moving effect for the load-bearing seat 13 and the support tube 1, and then cooperate to provide a flexible moving effect for the light-blocking panel parts such as the center baffle 901 as a whole.

[0047] Through the above technical scheme, 1. By connecting the sleeve 7 with the lifting component 2, and cooperating with the fixed sleeve 3 to support the screw 5 on one side of the lifting component 2, when the lifting component 2 is fully extended to the outside of the support tube 1, the threaded sleeve 6 is driven to move by rotating the screw 5 to cooperate with the sleeve 7 to move outside the lifting component 2 and simultaneously drive the supporting component 8 and the light blocking component 9 to move, so that the height of the light blocking component 9 can be adjusted separately on the outside of the lifting component 2, and when the lifting component 2 is lifted and lowered inside the support tube 1, the fixed sleeve 3 and the light blocking component 9 can be synchronously driven to lift and lower as a whole and cooperate with the telescopic limit component 12 to limit it to any position of the support tube 1, so that the light blocking component 9 can be flexibly adjusted when in use to reduce the labor intensity of manual operation, and when not in use, the height of the light blocking component 9 can be folded for easy storage in conjunction with the recovery of the lifting component 2; 2. By arranging connecting plates 8 at both ends of the T-shaped plate 801 02 can provide balanced connection and support for the light blocking component 9 at its upper and lower ends. At the same time, after the screw 5 drives the threaded sleeve 6 to drive the sleeve 7 to move, the T-plate 801 drives the light blocking component 9 to move together, so that the light blocking component 9 can adjust to any height and block light at different positions for the shooting scene; by passing the threaded rotating rod 1101 through the fixed sleeve 3 and cooperating with the vertical slot 10 to extend its end to the interior of the lifting rod 201 and connect with the arc top block 1102, so that when the threaded rotating rod 1101 drives the telescopic limit assembly 12 to limit the position of the lifting rod 201, the position of the fixed sleeve 3 is locked together, so that the positions of the fixed sleeve 3 and the lifting rod 201 on the inner and outer sides of the support tube 1 are always consistent, and the setting of the vertical slot 10 makes the moving paths of the threaded sleeve 6 and the T-plate 801 unrestricted when they are lifted together, thereby making the fixing and loosening operations of the lifting rod 201 and the fixed sleeve 3 more convenient.
