Description

Technical Field

[0001] The utility model relates to a light-shielding background cloth frame, belonging to the technical field of background cloth frames. Background Art

[0002] When taking photos, the light is often too bright, resulting in overexposure of the photos, resulting in poor shooting effects. In this case, a blackout background cloth is needed to block the light in order to reduce the brightness of the light and make the photos better. When using a blackout background cloth, it must be placed on a blackout background cloth stand for support and use.

[0003] Since the shading background cloth is usually large in area, the size of the shading background cloth frame that matches it is usually also large. The existing shading background cloth frame has no foldable storage structure, and cannot be folded and stored, resulting in the shading background cloth frame occupying a large storage space when not in use. In addition, the shading background cloth frame is very inconvenient to transport and use, and the large size makes it difficult to install a protective shell on the outside, which makes it easy to be damaged during transportation.

[0023] The first flip support leg 3 is connected to the main frame 1 via a first hinge block 8. A first storage groove 9 adapted to the second flip support leg 4 is provided on the inner side of the first flip support leg 3. The first storage groove 9 is used to fold and store the second flip support leg 4.

[0024] The second flip support leg 4 is rotatably connected to the end of the first storage slot 9 via a first rotating shaft 10. The front and rear sides of the end of the second flip support leg 4 are provided with second storage slots 11 adapted to the balancing support leg 5. The second storage slots 11 can fold and store the balancing support leg 5.

[0025] The balancing support leg 5 is hinged to the inner end of the second receiving groove 11 through the second rotating axis 12. A first fixed magnet 102 is provided at one end of the second receiving groove 11 away from the second rotating axis 12. A second fixed magnet 13 which is mutually adsorbed with the first fixed magnet 102 is provided at the end of the upper surface of the balancing support leg 5. The first fixed magnet 102 and the second fixed magnet 13 are arranged so that the balancing support leg 5 can be adsorbed in the second receiving groove 11 when folded and stored to prevent it from slipping.

[0026] The lower surface of the balancing support leg 5 is provided with an anti-skid convex strip 101 and a fixed support slot 14, in which a fixed support clip 15 is slidably arranged, and an anti-skid dial block 16 is arranged on the lower surface of the fixed support clip 15; the anti-skid convex strip 101 can prevent sliding during support, and the fixed support slot 14 facilitates the fixed support clip 15 to slide and fix the balancing support leg 5 therein to prevent the balancing support leg 5 from swinging up and down, and the anti-skid dial block 16 is used to dial the fixed support clip 15.

[0027] A driving shaft 17 is arranged in the light-shielding background cloth storage cavity 6, a light-shielding background cloth 18 is fixedly connected to the lower part of the driving shaft 17, and a weighting shaft 19 is fixedly connected to the end of the light-shielding background cloth 18.

The bolt hole blocks 26 and the fixing plug 27 can fix the folded foldable storage support frame 2 to the main frame 1.

[0030] like Figure 1-4As shown, the principle of the shading background cloth frame provided in this embodiment is as follows: when using the device, the fixed plugs 27 on both sides of the main frame body 1 should be pulled out from the bolt hole blocks 26, so that the first flip support leg 3 is reversed outward to ninety degrees, and then the second flip support leg 4 is reversed outward to ninety degrees from the first storage slot 9, and then the balance support leg 5 is reversed outward to ninety degrees from the second storage slot 11, and the two adjacent balance support legs 5 are limited and fixed on the same horizontal plane by toggling the fixed support card strip 15 in the fixed support card slot 14, and are in a vertical state with the second flip support leg 4, and finally the driving motor 23 will control the meshing first gear 24 and the second gear 25 to slowly place the shading background cloth 18 at the bottom of the device, and then fix the weighting shaft 19 between the two second flip support legs 4 through the first bolt 21, and then the shading background cloth receiver 7 will retract appropriately, so that the shading background cloth 18 is in a taut state;

[0031] When storing, the shading background cloth 18 should be properly loosened through the shading background cloth receiver 7, and then the first bolt 21 should be screwed to separate the weight shaft 19 from the second flip support leg 4, and then the driving motor 23 will control the meshing first gear 24 and the second gear 25 to slowly store the shading background cloth 18 into the shading background cloth storage cavity 6, and then the fixed support card strip 15 is pushed to the fixed support card slot 14 on either side, and the balance support leg 5 is flipped into the second storage slot 11, and fixed by magnetic attraction of the first fixed magnetic block 102 and the second fixed magnetic block 13, and then the second flip support leg 4 is flipped inward to the first storage slot 9, and finally the first flip support leg 3 is reversed inward to fit with the bottom of the lower surface of the main frame 1, and the fixed plug 27 is inserted into the bolt hole block 26 to complete the storage of the device.

[0032] The above description shows and describes the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the form disclosed herein.
