Claim 15:
16. A photography stand, comprising:
a central pipe, wherein a top of the central pipe is configured to mount photographic equipment;
a supporting frame connected to the central pipe and provided adjacent to a bottom of the central pipe, wherein the supporting frame moves relative to the central pipe along an axial direction of the central pipe, the supporting frame is unfolded when moving along the axial direction of the central pipe toward the bottom of the central pipe by a preset distance and then moving continuously toward the bottom of the central pipe, and the supporting frame is folded when moving along the axial direction of the central pipe toward the top of the central pipe, and wherein the supporting frame comprises a sliding seat and a plurality of supporting legs: the sliding seat is slidably sleeved on a periphery of the central pipe; an end of each supporting leg of the plurality of supporting legs is rotatably connected to the sliding seat; the plurality of supporting legs are arranged alternately on a periphery of the sliding seat when each supporting leg moves with the sliding seat along the axial direction of the central pipe toward the bottom of the central pipe by the preset distance and then moves continuously toward the bottom of the central pipe, each supporting leg rotates away from the central pipe and is unfolded and when each supporting leg moves with the sliding seat along the axial direction of the central pipe toward the top of the central pipe, each supporting leg rotates toward the central pipe and is folded;
a bushing, wherein the bushing is sleeved on the periphery of the central pipe; the sliding seat drives the plurality of supporting legs to extend out of the bushing through a bottom opening of the bushing and to unfold; and the plurality of supporting legs in a folded state are retracted and stored in the bushing through the bottom opening of the bushing; and
wherein
the supporting frame further comprises a plurality of first rotating shafts, a plurality of first elastic members, and gears connected and fixed with ends of the plurality of supporting legs: the end of each supporting leg is rotatably connected to the sliding seat through each first rotating shaft of the plurality of first rotating shafts: each supporting leg rotates relative to the sliding seat around an axial direction of each first rotating shaft; and the plurality of first rotating shafts are in one-to-one correspondence with the plurality of supporting legs;
each first elastic member of the plurality of first elastic members is configured to provide an elastic force for each supporting leg to drive each supporting leg to automatically unfold at the bottom of the central pipe; and the plurality of first elastic members are in one-to-one correspondence with the plurality of supporting legs;
a second elastic member is provided in the bushing: and the second elastic member is configured to drive the supporting frame to move along the axial direction of the central pipe toward the bottom of the central pipe and to unfold automatically; and
a drive slider, wherein the drive slider is provided on the central pipe and moves along the axial direction of the central pipe; the drive slider is adjacent to a top of the bushing and is connected to the bushing through the second elastic member; the drive slider comprises racks; and the second elastic member releases an elastic force, such that the drive slider drives the sliding seat to move along the axial direction of the central pipe toward the bottom of the central pipe; and
the gears and the racks are in one-to-one correspondence with the plurality of supporting legs quantitatively; and when the drive slider drives the sliding seat to move to a bottom of the bushing, the racks drive the gears to rotate, such that the supporting frame is unfolded.
