Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a tripod with a magnetic structure. Background Technology

[0002] Traditional tripods rely on mechanical latches to extend and retract their legs. Users must perform this in two steps: first, unlock the latches at the bottom of the tripod shaft, then manually pry open each leg one by one. For example, common spring-loaded tripods require pressing the latches to release the legs, then relying on springs to assist in extension. However, users still need to apply external force to adjust the angle and lock it again, which is quite cumbersome. Utility Model Content

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0024] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1 to 8 This utility model discloses a tripod with a magnetic structure, comprising a pole (1), a support foot (2), and a sliding structure. The pole (1) is fitted with a sliding sleeve (3) that can slide along its axis, and a fixed sleeve (4) is fixedly connected to the bottom of the pole. One end of the support foot (2) is pivotally connected to the sliding sleeve (3), and the inner wall of the support foot (2) is pivotally connected to the fixed sleeve (4) via a connecting rod. The sliding structure consists of a fixed seat (5), a sliding seat (6), and a sliding rod (7). The fixed seat (5) is fixed to the bottom of the pole and has a through hole (51). The sliding rod (7) passes through… Located in the through hole (51), the slide rod (7) is fitted with a return spring (8). One end of the return spring (8) abuts against the fixed seat (5), and the other end of the return spring (8) abuts against the slide seat (6). The slide seat (6) has a single-hole first mounting groove (61) on its side, and the inner wall of the support foot (2) corresponding to the fixed sleeve (4) has a double-hole second mounting groove (21). The magnets in the first mounting groove (61) and the lower hole second mounting groove (21) are configured to attract each other, and the magnets in the first mounting groove (61) and the upper hole second mounting groove (21) are configured to repel each other.

[0027] The rod body (1) is a hollow cylinder, and the sliding sleeve (3) slides up and down along the axis of the rod body. One end of the support foot (2) is pivotally connected to the sliding sleeve (3) via a pin, and the other end is hinged to the fixed sleeve (4) via a connecting rod to achieve linkage extension and retraction. The fixed seat (5) is threaded to the end of the rod body, and its internal through hole (51) is precisely matched with the sliding rod (7), restricting the sliding seat (6) to move only in the vertical direction. The sliding seat (6) has a first mounting groove (61) on its side, into which a first magnet (S pole) is embedded; in the second mounting groove (21) with double holes on the inner wall of the support foot (2), a second magnet (N pole) is embedded in the lower hole, and a third magnet (S pole) is embedded in the upper hole. Under normal conditions, the first magnet attracts the second magnet in the lower hole, causing the support foot (2) to retract; when the sliding seat (6) is pressed, the first magnet moves up to repel the third magnet in the upper hole, pushing the support foot (2) to unfold outward. After being compressed, the return spring (8) forces the sliding seat (6) to return to its original position through elastic deformation. The magnetic repulsion priority triggering mechanism replaces the traditional mechanical buckle, realizing one-click pop-out; the cooperation between the slide bar (7) and the through hole (51) ensures the linear movement of the sliding seat (6) and avoids offset jamming; the magnetic attraction / magnetic repulsion dual-mode switching is stable and reliable, reducing the complexity of operation.

[0028] Please see Figures 1 to 8 In another embodiment, the outer wall of the rod body (1) is provided with three equally angled sliding grooves (11) and the inner wall of the sliding sleeve (3) is provided with a slider (31) that can move along the sliding grooves (11).

[0029] Three guide grooves (11) are milled on the outer wall of the rod body (1) at 120° intervals. Three sets of raised sliders (31) are provided on the inner wall of the sliding sleeve (3), and their cross-sectional shape matches the grooves. When the sliding sleeve (3) moves, the sliders (31) move linearly along the grooves (11), restricting the rotation of the sliding sleeve and reducing friction. The combination of the grooves (11) and the sliders (31) forms an anti-torsion structure to ensure the consistency of the unfolding direction of the support feet (2).

[0030] Please see Figures 1 to 8 In another embodiment, the inner wall of the sliding space (52) of the fixed seat (5) extends to form an annular first stop (53), and the outer wall of the sliding seat (6) is correspondingly provided with a second stop (62) that can abut against the first stop (53).

[0031] The top of the sliding space (52) inside the fixed seat (5) is machined with a first annular stop (53), and the outer wall of the sliding seat (6) is machined with a second outwardly protruding stop (62). When the sliding seat (6) moves to its limit position, the second stop (62) contacts the first stop (53), preventing further displacement and avoiding the slide rod (7) from dislodging from the through hole (51). The double stop structure limits the sliding stroke and prevents it from falling off.

[0032] Please see Figures 1 to 8In another embodiment, the opening ends of the first mounting groove (61) and the second mounting groove (21) are both closed by a removable sealing plate (9).

[0033] Threaded holes are provided at the opening ends of the first mounting slot (61) and the second mounting slot (21), and the sealing plate (9) is fixed by screws to cover the magnet mounting position. This prevents the magnet from slipping out of the first mounting slot (61) and the second mounting slot (21).

[0034] Please see Figures 1 to 8 In another embodiment, the two ends of the return spring (8) abut against the top surface of the fixed seat (5) and the top surface of the sliding seat (6), respectively.

[0035] The return spring (8) is fitted on the outside of the slide rod (7), with its upper end pressing against the annular groove on the top of the sliding seat (6) and its lower end abutting against the top plane of the fixed seat (5). When the sliding seat (6) is pressed, the spring (8) is compressed and stores energy; after the external force is released, the spring (8) rebounds and pushes the sliding seat down to reset.

[0036] Please see Figures 1 to 8 In another embodiment, the lower hole of the two magnetic mounting holes of the second mounting groove (21) is arranged 15-30mm above the upper hole.

[0037] The distance between the two magnet mounting holes in the second mounting slot (21) is set to 20mm. When the sliding seat (6) drives the first magnet to rise, the first magnet first approaches the lower hole magnet (attractive state), and then contacts the upper hole magnet (repulsive state). The optimized spacing avoids premature decay of magnetic force and ensures stable unfolding force of the support foot (2). A spacing of 15-30mm balances the magnetic strength and stroke requirements; avoids interference caused by excessively small spacing between the two magnetic poles.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
