Technical Field

[0001] This utility model relates to a floor stand, and more particularly to a floor stand, belonging to the field of camera stand technology. Background Technology

[0002] In the field of videography, a floor stand (also known as a tripod or camera stand) is a tool used to stabilize and support a camera or other shooting equipment, ensuring stable footage, especially important when shooting for extended periods or using telephoto lenses.

[0003] Most floor-standing stands on the market today use a fixed height design or a bolt-adjustable height design. Fixed-height stands limit the operator's ability to adjust the height, significantly reducing their flexibility. Stands with bolt-adjustable height require repeated rotation of the bolts to lock the height, which undoubtedly increases the inconvenience for operators.

[0004] Therefore, there is an urgent need to improve a type of floor support to solve the aforementioned problems. Utility Model Content

[0008] Preferably, the outer wall of the second support rod has guide grooves on opposite sides, and the inner wall of the sliding ring has guide blocks on opposite sides that are slidably connected to the guide grooves. The guide grooves are used for vertical sliding guidance of the sliding ring.

[0009] Preferably, a disc is arranged below the rotating disc and rotationally connected with the connecting rod, and a plurality of sliding grooves are formed in the disc and a sliding rod is slidably connected in the sliding grooves.

[0010] Preferably, a plurality of arc-shaped sliding grooves are formed in the rotating disc, an auxiliary rod is slidably connected in the arc-shaped sliding grooves, one end of the auxiliary rod is fixedly connected with the upper surface of the sliding rod, and one end of the sliding rod is fixedly connected with the limiting block.

[0011] Preferably, a connecting ring is arranged below the first supporting rod, an annular groove is formed between the connecting ring and the first supporting rod and outwardly extending from the connecting ring, the connecting ring is fixedly connected with the first supporting rod through a connecting plate, an accommodation groove is formed in the inner side of the connecting ring, and the rotating block is rotationally connected with one end of the first supporting rod and the accommodation groove.

[0012] Preferably, the limiting block and the limiting groove formed in the sliding ring are in the same horizontal plane.
