[0052] Reference Figures 1 to 6In an embodiment of the utility model, the foot stand includes a fixing sleeve 10, a middle shaft 20 and at least three supporting feet 30; the fixing sleeve 10 is provided with a through hole; the middle shaft 20 is movably inserted into the through hole along its axial direction, and the middle shaft 20 is suitable for supporting an object; the at least three supporting feet 30 are all telescopic supporting feet, one end of each of the supporting feet 30 is rotatably arranged on the fixing sleeve 10 through a foot joint 40, and each foot joint 40 and the middle shaft 20 are connected through a connecting rod 50, and the two ends of the connecting rod 50 are rotatably connected with the foot joint 40 and the middle shaft 20 respectively; wherein the foot joint 40 can be a one-piece structure or a split structure, which is not limited in this paper.

[0053] In the embodiment, the fixing sleeve 10 can be a one-piece structure or assembled from two or more components, which is not limited here.

[0054] The middle shaft 20 can be a tubular structure with a square or circular cross-section, which can be a single shaft or a plurality of sequentially connected pull rod structures to achieve manual stretching to adjust its length and thus adjust the supporting height. Here, the structure of the middle shaft 20 is not limited.

[0055] To facilitate the connection of objects such as cameras, in the embodiment, a supporting platform 70 can be installed at the top end of the middle shaft 20, and a standard 1 / 4 or 3 / 8 standard screw or the like can be provided on the supporting platform 70, which is not limited here.

[0056] It can be understood that, by installing the foot joint 40 at one end of the supporting foot 30 and rotatably arranging the connecting rod 50 on the foot joint 40, the supporting foot 30 does not need to be provided with a sliding groove and a sliding block structure, so that a conventional hollow rod-shaped telescopic supporting foot can be used as the supporting foot 30 of the foot stand, thereby achieving telescopic adjustment of the supporting foot 30, expanding the adjustable range of the supporting height of the foot stand, enriching the application scenarios, and also reducing the manufacturing cost of the foot stand.

[0057] It should be noted that, as shown in Figure 6 , the telescopic supporting foot includes two or more pipe bodies, which can be manually pulled out or pushed back to achieve length adjustment and thus change the supporting height of the foot stand.

[0058] To further improve the stability of the foot stand in supporting objects, referring to Figure 3 and Figure 5 , in an embodiment, the foot stand can further include a connecting seat 21, which is arranged at the bottom of the middle shaft 20, and the connecting rod 50 is rotatably arranged on the connecting seat 21. The connecting seat 21 can also be suitable for hanging a counterweight, thereby further enhancing the stability of the foot stand in supporting objects.

[0059] Referring to Figures 5 to 18In some embodiments, the fixing sleeve 10 of the tripod may be provided with a deformable portion 121 constituting at least a portion of the hole wall of the through hole, and the foot joint 40 may be provided with an abutting surface 401 disposed opposite to the deformable portion 121; Figure 9 As shown, when the support legs 30 are in the unfolded state, the deformable portion 121 is in close contact with the central axis 20; Figure 8 As shown, when the support legs 30 are in the closed position, there is a gap between the deformable portion 121 and the central axis 20. This arrangement eliminates the need for an additional locking mechanism, simplifies the structure of the tripod, and helps save costs. Furthermore, it eliminates the need for operating steps such as pulling a lever or turning a knob, making it more convenient for users.

[0060] In the first case, if Figures 1 to 15 As shown, the foot joint 40 is an integrated structure. In this case, the abutting surface 401 is provided on the top end of the foot joint 40 , and one end of the connecting rod 50 is rotatably provided on the foot joint 40 .

[0062] Of course, in some embodiments, the structure of the foot joint 40 on each supporting foot 30 can be the same or different, such as one of them is an integrated structure and the other two are split structures, which is not limited here.

[0063] It should be emphasized that the technical solution proposed by the present invention is not limited to the above two situations. Those skilled in the art can make appropriate or corresponding deformation designs to the foot joint 40 based on their experience (such as changing the foot joint 40 to a split structure with more segments). Any feature such as a connecting structure, component or assembly is set on the support foot 30 (the feature is collectively referred to as the foot joint 30), and the connecting rod 50 is rotated and set on the feature, so that the support foot 30 does not need to be provided with a slide groove and a slider, thereby achieving the purpose of using a conventional hollow rod-shaped telescopic support foot as the support foot 30 of the tripod, which is within the concept of the present invention.

[0064] Furthermore, in order to facilitate the processing of the structures on each fixing sleeve 10 and improve the convenience of assembly, Figures 5 to 7 As shown, the fixing sleeve 10 may include a first fixing seat 11 and a second fixing seat 12. The first fixing seat 11 is connected to the second fixing seat 12 and is surrounded to form a plurality of accommodating notches 10a that are arranged one-to-one with the supporting legs 30. The end of the leg joint 40 is rotatably arranged in the accommodating notch 10a.

[0065] In the embodiment, a protrusion can be arranged between each accommodating gap 10a and the through hole on the second fixing seat 12 to form the deformation part 121.

[0066] To make the opening range of the supporting leg 30 wider, and meet the support requirements of more use scenarios, please refer to Figures 12 to 15 , in another embodiment, the foot stool can further include a locking assembly arranged on the fixing sleeve 10 and used for locking the middle shaft 20 when the supporting leg 30 is in the unfolded state. In this embodiment, there should always be a gap between the middle shaft 20 and the hole wall of the through hole to ensure that the supporting leg 30 can rotate in a larger range.

[0067] In the embodiment, the locking assembly includes a control handle and a locking piece, the locking piece is arranged in the fixing sleeve 10, and the control handle is in abutment with the locking piece and is used for controlling the locking piece to loosen or lock the middle shaft 20. In the embodiment, the control handle can be a buckle 61 or a knob, which is not limited herein.

[0068] As shown in Figures 12 to 15 , when the control handle is a buckle 61 and the locking piece is a movable block 62, the fixing sleeve 10 is provided with a mounting hole in communication with the through hole, the movable block 62 is arranged in the mounting hole and can extend into the through hole, and one end of the buckle 61 is rotationally arranged in the mounting hole and abuts against the movable block 62.

[0069] In addition, in the embodiment, when the foot joint 40 adopts an integrated structure, one end of the connecting rod 50 is rotationally arranged on the foot joint 40; when the foot joint 40 adopts a split structure, the foot joint 40 includes a first joint 41 and a second joint 42 which are arranged at intervals on the supporting leg 30, and one end of the connecting rod 50 is rotationally arranged on the second joint 42.

[0070] In the technical solution, there is always a gap between the middle shaft 20 of the foot stool and the hole wall of the through hole of the fixing sleeve 10, which realizes stepless adjustment of the opening angle of the supporting leg 30 between 0 and 90 degrees, and the locking structure is used to lock the middle shaft 20, which effectively guarantees the support stability requirement of the supporting leg 30 at different opening angles, so that the foot stool can adapt to different application scenarios such as different terrains or table surfaces, and the user can select any angle according to the use requirement, which greatly improves the convenience and operability.

[0071] The above description is only optional embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
