[0030] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model is further explained in detail below in combination with the drawings and specific embodiments.

[0031] As Figures 1 to 6 shown, the embodiment provides a novel photographic tripod, which is designed to improve stability, safety and operation convenience. The tripod mainly comprises a triangular seat 1, a plurality of connecting heads 2 hinged around the triangular seat 1, and supporting legs 3 provided on the connecting heads 2.

[0032] Angle adjusting mechanism

[0033] The angle adjusting mechanism is provided between the triangular seat 1 and the connecting head 2. The angle adjusting mechanism comprises a plurality of step-shaped limiting teeth 11, which are arranged on the triangular seat 1 and form an adjustable gear structure. The connecting head 2 is rotationally connected with a limiting buckle 4, and the limiting buckle 4 is provided with a top head 41 capable of abutting against the limiting tooth 11 to prevent the rotation of the connecting head 2. A first elastic reset member 42 is provided between the limiting buckle 4 and the connecting head 2, which is preferably a torsion spring and can provide the necessary elastic force for the limiting buckle 4 during use, ensuring the stability of the limiting buckle 4 at different angles.

[0034] When the user unfolds the supporting leg 3, he / she only needs to press the limiting buckle 4 and stretch the supporting leg 3 outward. After releasing the limiting buckle 4, the limiting buckle 4 can be automatically clamped into the limiting tooth 11 corresponding to the required angle, thereby realizing stable adjustment. When folding the supporting leg 3, the user only needs to simply pull the supporting leg 3 towards the center to complete the operation, greatly simplifying the use process and improving the user experience.

[0035] In order to further enhance the convenience of angle adjustment, the inner end of the limiting buckle 4 is provided with a trigger head 44, the side of the limiting buckle 4 is provided with a spring plunger 43, and the corresponding position of the connecting head 2 is provided with a positioning groove 21 (spherical groove) capable of cooperating with the spring plunger 43.

[0036] When the support leg 3 is folded, the spring plunger 43 cooperates with the corresponding positioning groove 21, at this time, the limiting buckle 4 is clamped, so that the top head 41 is separated from the limiting tooth 11.

[0037] During the swinging of the support leg 3 in the opening direction, the lowermost limiting tooth 11 can trigger the trigger head 44 to make the spring plunger 43 disengage from the corresponding positioning groove 21. This triggering action is very critical because it will make the spring plunger 43 disengage from the positioning groove 21, thereby releasing the clamping state of the limiting buckle 4. At this time, the limiting buckle 4 can move freely, and the top head 41 on the limiting buckle 4 can cooperate with the corresponding limiting tooth 11 under the action of the first elastic reset member 42.

[0038] Such a design can make the limiting buckle 4 be locked during the unfolding of the support leg, and cannot touch each limiting tooth 11, so that the support leg can be unfolded smoothly. The limiting buckle 4 is only unlocked during the folding of the support leg, and cooperates with each limiting tooth 11.

[0039] Anti-folding mechanism

[0040] In order to avoid the safety hazard caused by the accidental folding of the support leg 3 during use, an anti-folding mechanism is further provided between the triangular seat 1 and the connecting head 2. The mechanism includes an anti-folding member 5 provided at the bottom of the triangular seat 1, which can move up and down and can rotate. At the same time, the anti-folding member 5 and the triangular seat 1 are provided with a second elastic reset member 51 (preferably a spring), which can continuously provide downward elastic force to ensure that the anti-folding member 5 is always in an effective working state.

[0041] The lower part of the anti-folding member 5 is provided with a plurality of outwardly extending blocking arms 52. When these blocking arms 52 are aligned with the corresponding connecting head 2, they can effectively block the inward folding of the support leg 3. More specifically, a central hole 12 is provided at the center of the bottom of the triangular seat 1, and the upper part of the anti-folding member 5 is inserted into the central hole 12. In order to ensure that the anti-folding member 5 moves up and down, the upper part of the anti-folding member 5 is further provided with an outwardly extending positioning plate 53, and the shape of the positioning plate 53 and the shape of the central hole 12 are adapted, which are non-circular designs (such as triangular, polygonal or special-shaped). The side wall of the central hole 12 is provided with a plurality of positioning grooves 121, and the positioning grooves 121 are provided at different heights, that is, the positioning plate 53 can be clamped in the positioning grooves 121 at different heights. These positioning grooves 121 can provide fixing points at different heights, so that the positioning plate 53 can be clamped at different heights.

[0042] Moreover, when the positioning plate 53 is screwed into the positioning groove 121, the blocking arm 52 will be aligned with and block the corresponding connecting head 2, thus avoiding accidental folding. When the positioning plate 53 is unscrewed from the positioning groove 121, the anti-folding member 5 can only move up and down, and the blocking arm 52 is misaligned with the connecting head 2, ensuring the flexibility of operation.

[0043] To further enhance the stability of the tripod, the anti-folding member 5 is provided with a hook 54 at the bottom, and the user can hang a counterweight on the hook 54. By adding a counterweight, the user can effectively improve the stability of the tripod in strong winds or uneven terrain, ensuring the safety and stability of the shooting equipment.

[0044] The embodiment greatly improves the functionality and safety of the tripod through structural optimization and simple user operation, providing more reliable support for photography work.

[0045] Leg locking system

[0046] The leg locking system of the embodiment is designed to improve the stability and ease of operation of the legs. Specifically, the leg 3 is composed of an inner tube 31 and an outer tube 32, both of which are polygonal tubes, such as hexagonal tubes, octagonal tubes, or even other special-shaped tubes. This polygonal design not only has a unique appearance, but also provides good torsional resistance, making the legs less likely to rotate or loosen during use.

[0047] At the junction of the inner tube 31 and the outer tube 32, a locking system is provided. The locking system includes a fixed sleeve 33 fixed to the upper end of the outer tube 32, a connecting sleeve 34 provided on the fixed sleeve 33, a locking sleeve 35 rotatably connected to the connecting sleeve 34, and a movable sleeve 36 sleeved on the inner tube 31 and threadedly connected with the locking sleeve 35.

[0048] Specifically, the fixed sleeve 33 serves as a support base. The inner side wall of the connecting sleeve 34 is provided with a first inclined surface 341 that gradually tilts outward from bottom to top. The inclined design here makes the force transmission more reasonable during locking, effectively increasing the friction and thus improving the locking effect. The outer side wall of the movable sleeve 36 is provided with a second inclined surface 361 that cooperates with the first inclined surface 341. This cooperative design ensures that the two components can generate mutual forces during locking and unlocking.

[0049] When the locking sleeve 35 rotates, it drives the movable sleeve 36 to move relative to the connecting sleeve 34, approaching or moving away from the connecting sleeve 34. Specifically, when the locking sleeve 35 rotates clockwise, the movable sleeve 36 will approach the connecting sleeve 34, and the first inclined surface 341 will press the second inclined surface 361 inward, generating a locking effect, thereby realizing the close combination between the inner tube 31 and the outer tube 32. This process effectively prevents the loosening of the support foot due to gravity or external force during use, ensuring stability.

[0050] On the contrary, when the user needs to adjust or fold the support foot, he only needs to rotate the locking sleeve 35 counterclockwise, at which time the movable sleeve 36 will move away from the connecting sleeve 34, and the first inclined surface 341 will release the second inclined surface 361, realizing the unlocking between the inner tube 31 and the outer tube 32. This design makes the entire operation process simple and clear, and the user can complete the adjustment in a short time, greatly improving the convenience of use.

[0051] Support foot spikes and counterweights

[0052] The support foot 3 in this embodiment is designed with detachable foot spikes 6 at the lower end, which not only enhances the stability of the support foot, but also provides flexibility for different use requirements. The upper end of the foot spike 6 is also detachably connected with a counterweight 7, which is cleverly placed inside the support foot 3 to ensure the overall structure is beautiful and balanced.

[0053] The foot spike 6 is connected to the lower end of the support foot 3 by threading, in addition, a sealing sleeve 61 is provided between the foot spike 6 and the support foot 3, which not only prevents dust and moisture from entering the inside of the support foot, but also further enhances the stability of the connection and prolongs the service life of the equipment.

[0054] The upper end of the foot spike 6 is provided with a first threaded hole 62, so that the counterweight 7 can be connected to the foot spike 6 by rotating. The lower end of the counterweight 7 is provided with an external thread 71 that can cooperate with the first threaded hole 62. In addition, the upper end of the counterweight 7 is provided with a second threaded hole 72 with the same size specifications as the first threaded hole 62, so that the user can add or remove the counterweight 7 according to different shooting environments and requirements, to achieve the best balance effect.

[0055] This combination of foot spikes and counterweights makes it very convenient for users to adjust. Users only need to easily rotate the counterweight 7 to realize the connection or disconnection with the foot spike 6, without the need for additional tools. This simple operation method is particularly suitable for dynamic shooting environments and can quickly respond to different shooting conditions.
