Description

Technical Field

[0001] The utility model belongs to the technical field of photographic stands, and in particular relates to a movable and adjustable film and television photographic stand. Background Art

[0002] A photography stand is a device used to hold a camera or camcorder and keep it in a vertical or horizontal position. It is usually made of metal or plastic and has adjustable brackets and clips that can easily adjust the angle and height for taking photos or videos. Photography stands are commonly used in studios, studios, photo studios, home photography and other fields.

[0003] In the prior art, after searching, Chinese Patent No. CN202022072004.4 discloses a multifunctional film and television photography stand, including a support plate, a mounting plate, a connecting pillar, a height adjustment branch pipe, a protective tube, a threaded rod, a bearing, a sliding buckle groove, a slider, a compression spring, a push plate, a clamping groove, a clamping plate, a pressing rod, a rotating slot and a rotating plug block. A rotating rod is provided at the right end of the rotating plug block, and a movable slot for cooperating with the rotating rod is provided on the right side wall of the rotating slot. A control rotating rod is plugged into the position on the left side of the rotating slot on the height adjustment branch pipe.

[0004] In the actual process of filming, the position of the camera stand needs to be constantly changed according to different shooting angles. However, since most of the existing ones are tripod structures, once the structure at one end shakes or is damaged, the entire camera stand will become unstable and fall over, causing damage to the camera installed on the top.

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

[0006] In view of the problems in the related technology, the utility model provides a movable and adjustable video photography stand to overcome the above technical problems existing in the existing related technology.

[0032] There are three groups of the support frames 2 and the extension frames 3, three groups of the adapter plates 5 and the cross bracing plates 6, and three groups of the rolling components 7.

[0033] When the lifting device 9 is lowered below the mounting base 1, a thrust is generated on the cross brace 6 to push the adapter plate 5 to rotate downward together, until the lifting device 9 continues to descend and pushes the cross brace 6 to be flush with the bottom of the base 4, so that the rolling assembly 7 under the adapter plate 5 is supported on the ground, so that the base 4 is separated from the ground and the support frame 2 is pushed to move. After moving to the required position, the lifting device 9 is rotated in the opposite direction to lift it upward and drive the cross brace 6 to flip upward to drive the adapter plate 5 to flip and tilt, and then drive the rolling assembly 7 to leave the ground, and then stop rotating the lifting device 9 so that the base 4 is supported on the ground again.

[0034] The utility model arranges the rolling assembly 7 below the adapter plate 5. When the support frame 2 and the extension frame 3 need to be moved as a whole, the lifting device 9 can be driven to descend or ascend to drive the cross brace plate 6 and the adapter plate 5 to flip over, thereby changing the supporting state of the rolling assembly 7. The lifting device 9 can be coordinated to descend to a certain height according to the extension length of the extension frame 3, so that when the base 4 is supported on the ground, the adapter plate 5 and the cross brace plate 6 on the inner side thereof are tilted and supported on the inner side of the extension frame 3 to increase the inner support strength. At the same time, the rolling assembly 7 is driven and adjusted to an inclined state away from the ground to prevent it from arbitrarily driving the extension frame 3 to move, so that the support frame 2 and the extension frame 3 are more stable and safe when supporting the camera.

[0035] In one embodiment, for the above-mentioned mounting base 1, the mounting base 1 includes a mounting plate 101, and the outer surface of the mounting plate 101 is fixedly connected with a connecting ear 102, and the top of the support frame 2 is rotatably connected to the inner wall of the connecting ear 102, and the number of the connecting ears 102 is three groups.

[0036] By arranging three groups of connecting ears 102 on the outer side of the mounting plate 101, positioning and mounting points can be provided for the corresponding three groups of supporting frames 2, so that the three groups of supporting frames 2 and the extension frames 3 are supported in a triangular manner below the mounting plate 101, providing stable support for the mounting plate 101.

[0037] In one embodiment, for the extension frame 3 , the extension frame 3 includes a sliding sleeve 301 , an extension rod 302 is fixedly mounted on the bottom of the sliding sleeve 301 , and the bottom of the extension rod 302 is rotatably connected to the inside of the base 4 .

[0038] The extension rod 302 is supported on the inner side of the support frame 2 by the sliding sleeve 301, so that the sliding sleeve 301 can be pushed or pulled to slide on the outside of the support frame 2 to recover or unfold the extended length of the extension rod 302, thereby providing a flexible support height for the support frame 2, and further providing an adjustable support height for the camera equipment.

[0040] The mounting sleeve 701 is fixed to the outer side of the adapter plate 5 so that the roller 702 is connected underneath it. When the adapter plate 5 is lowered to the same horizontal line as the base 4, the bottom of the roller 702 is supported on the ground at a certain height from the base 4, so as to achieve the effect of rolling to drive the support frame 2 to move.

[0041] In one embodiment, for the above-mentioned lifting device 9, the lifting device 9 includes a lifting screw 901, a rotating sleeve 902 is fixedly installed on the outer surface of the lifting screw 901, a threaded sleeve 903 is threadedly connected to the outer surface of the lifting screw 901, a connecting rotating plate 904 is fixedly connected to the outer surface of the threaded sleeve 903, and the connecting rotating plate 904 is rotatably connected to the cross support plate 6.

[0042] By extending the top of the lifting screw 901 to the inside of the base 8, when the lifting screw 901 is rotated, it drives the threaded sleeve 903 threadedly connected to it to move downward, and at the same time, the connecting plate 904 at the bottom of the threaded sleeve 903 pushes the cross support plate 6 to move downward and drives the adapter plate 5 at one end to flip downward, until the threaded sleeve 903 continues to descend so that the adapter plate 5 and the base 4 are in the same horizontal plane, the roller 702 at the bottom contacts the ground, and the base 4 is supported off the ground, and the threaded sleeve 903 stops moving.

[0043] By connecting the end of the cross brace 6 with the connecting plate 904, when the rotating sleeve 902 is rotated to make the lifting screw 901 rotate in the forward direction, the threaded sleeve 903 is driven to descend, and the reverse rotation is used to drive the threaded sleeve 903 to rise to lift the cross brace 6 and flip it upward.
