[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] As Figures 1 to 5 shown, the tripod structure includes a base 1, a base cylinder 2, a support arm 3, a support arm slip ring 4, a support arm hinge rod 5, a base cylinder slip ring 6, a locking rod 7, and a tripod flange 8, wherein: the base 1 is a disc structure, and a plurality of hinge joints 101 are symmetrically arranged on the outer edge of the base 1. The base is the foundation of this structure, and other components are mainly connected to the base and rotate or slide relative to the base during use. In the figure, the base cylinder 2 is vertically sleeved on the base 1. The base cylinder is a connecting body connecting the base and the flange. Other components or devices can be connected to the flange. The base cylinder is also a component that is fixed relative to the base during use and storage, and serves as the track for the sliding of the base cylinder slip ring component.

[0025] In the figure, a U-shaped head 301 is installed at the inner end of the support arm 3. The U-shaped head 301 is connected to the hinge joint 101 through a rotating shaft. A positioning ring 302 is sleeved on the outer end of the support arm 3, and a receiving head 303 is arranged on the positioning ring 302. Specifically, the U-shaped head 301 is used to connect the base and the support arm component, is fixedly connected to the support arm, and is selectively connected to the base through a shaft to realize the opening and folding of the support arm. In addition, when the support arm is used as the main support component of the tripod, it plays a role in supporting and stabilizing the tripod and the connected equipment.

[0026] In the figure, the support arm slip ring 4 is movably sleeved on the support arm 3. The bottom of the support arm slip ring 4 extends to both sides to form a horizontal seat 401. Vertical rotating shaft holes 402 are arranged on both sides of the horizontal seat 401. A horizontal rotating shaft hole 403 is opened on the vertical side surface of the support arm slip ring 4. Positioning shafts are arranged in both the vertical rotating shaft hole 402 and the horizontal rotating shaft hole 403. Specifically, when in use and storage, under the connection of the support arm hinge rod, as the support cylinder slip ring moves, the support arm rotates around the connection shaft of the support cylinder and the support arm end piece, so as to realize the storage function. The support arm hinge rod is used to connect the support arm slip ring and the support cylinder slip ring, so that the two components are linked, and the support arm does not need to be operated separately, so that the three support arms are unfolded and folded synchronously.

[0027] In the figure, one end of the support arm hinge rod 5 is provided with an end hole, and the other end of the support arm hinge rod 5 is provided with a buckle. The end hole is sleeved on the positioning shaft of a horizontal rotating shaft hole 403 on one side, and the buckle is detachably installed on the positioning shaft of the horizontal rotating shaft hole 403 on the other side; the base cylinder slip ring 6 is sleeved on the base cylinder 2, and a plurality of slip ring hinge seats 601 are symmetrically arranged on the base cylinder slip ring 6; one end through hole of the locking rod 7 is installed on the slip ring hinge seat 601 through a rotating shaft, and the buckle at the other end of the locking rod 7 is detachably installed on the positioning shaft of the horizontal rotating shaft hole 403; the tripod flange 8 is fixed on the top of the base cylinder 2, and a plurality of receiving slots 801 are symmetrically arranged on the outer edge of the tripod flange 8, and the receiving slots 801 are used to engage the receiving head 303. Specifically, the base cylinder slip ring realizes the unfolding and storage of the support arm by moving up and down on the base cylinder. The support arm fixing part realizes limit locking with the flange fixing part when the support arm is retracted to avoid shaking.

[0028] In the figure, a support foot 9 is installed at the end of the support arm 3 through a universal head. Specifically, the support foot serves as the support between the support arm and the ground. By rotating the universal head, the end face of the support foot can be completely in contact with the ground to achieve the largest stress area. At the same time, there are holes on the support foot, and a ground anchor can be used to fix the support foot to the ground to achieve higher stability.

[0029] In this embodiment, a handle 10 is installed on the base cylinder 2. In addition, a plurality of weight-reducing holes 102 are symmetrically formed in the base 1, and the weight-reducing holes 102 are arc-shaped waist holes. A plurality of weight-reducing grooves are symmetrically formed on both the support arm hinge rod 5 and the locking rod 7. The swinging plane of the locking rod 7 in the slip ring hinge seat 601 is tangent to the outer circle of the base cylinder slip ring 6, ensuring that the locking rod 7 can be smoothly installed in the slip ring hinge seat 601 and the horizontal rotating shaft hole 403.

[0030] During actual operation, this structure adopts a support arm folding structure, and the support arm can swing 180° around the base. On the one hand, this structure is convenient for storage. When the support arm is attached to the base cylinder, the smallest floor area can be achieved. On the other hand, this structure can achieve the largest floor area. When the support arm and the base cylinder are arranged at 90°, at this time, it can adapt to the support and fixation of equipment in harsh outdoor environments and can resist certain impact and wind load. When folding and storing, the base cylinder slip ring slides downward, and the support arm drives the support arm slip ring and the support arm hinge rod to rotate until the support arm fixing member and the flange fixing member are limited; after storage, a cylindrical shape is formed, and the storage size is small. This tripod is suitable for loading large equipment and has sufficient stability and rigidity to ensure the smooth operation of the installed equipment. In addition, this structure is also equipped with a support arm slip ring, a support arm hinge rod, a base cylinder slip ring and a locking rod. The base cylinder slip ring and the locking rod can lock the swinging angle of the support arm. For example, the angle between the support arm and the base cylinder can be locked at 90°; the support arm hinge rod and the support arm slip ring can improve the overall stiffness of the product. Finally, the storage card slot and the storage head of this structure can achieve detachable splicing, which is convenient for the storage and fixation of the tripod structure. When the support arm is closely attached to the base cylinder, the storage head can be inserted into the storage card slot. Under the action of external force, the storage card slot has a certain deformation ability to release the storage head.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
