Description

Technical Field

[0001] This utility model relates to the field of tripod technology, and in particular to a tripod anti-folding structure. Background Technology

[0002] Tripods, as an important photographic tool, are widely used in photography and videography. Their main function is to provide stable support for cameras, camcorders, and other equipment to prevent image blurring caused by hand shake, thereby ensuring image quality. However, existing tripods generally suffer from the following shortcomings in practical use:

[0003] Accidental Collapse Risk: Traditional tripods typically feature a foldable design for easy carrying and storage. Their three legs are connected by hinges or similar structures, and when unfolded, they rely on friction or a simple locking mechanism for stability. However, due to external impacts, uneven ground, or loosening of the locking mechanism, tripods are prone to accidental collapse during use, causing the supported equipment to tip over, resulting in equipment damage or even personal injury. This risk is particularly pronounced in complex outdoor environments.

[0004] Insufficient stability and safety: Existing tripod anti-collision structures are often simply designed with low strength, making them unable to effectively resist significant external impacts. For example, some tripods use simple snap-on or friction-based locking mechanisms, which are prone to wear or loosening after prolonged use, leading to a decrease in anti-collision effectiveness. Furthermore, some tripods lack effective connecting structures between their support legs, resulting in poor overall rigidity and a tendency to sway or tilt.

[0005] Inconvenient to operate: While some tripods have a certain anti-collapsing function, their complex structure and cumbersome operation cause inconvenience to users. For example, some tripods require users to manually tighten multiple locking screws to achieve the anti-collapsing function, which is not only time-consuming and laborious, but also easy to forget to do so, leading to safety hazards.

[0006] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a tripod anti-collapsing structure that is simple in structure, easy to use, and stable and safe.

[0008] This utility model is achieved through the following technical solution:

[0009] To solve the above-mentioned technical problems, this utility model provides a tripod anti-collision structure, including a tripod base and three legs evenly and movably connected around the periphery of the tripod base. An anti-collision member is movably connected to the bottom surface of the tripod base, and the anti-collision member can move between a first position and a second position. In the first position, the anti-collision member prevents the legs from rotating in the collapsing direction; in the second position, the anti-collision member releases its obstruction of the legs and is at least partially retracted and hidden within the tripod base or between the legs.

[0010] The anti-closing component has three outwardly extending stop arms evenly arranged around its perimeter. The lower side of the outer end of each stop arm is provided with a limiting slope. The inner side of the support leg seat is provided with a clearance slot into which the stop arms can extend. The lower side of the clearance slot is provided with a support surface. The support surface can abut against the limiting slope to prevent the support leg seat from rotating in the closing direction.

[0011] In order to further solve the technical problem to be solved by this utility model, the tripod anti-collision structure provided by this utility model has the anti-collision component rotatably connected to the bottom surface of the tripod base and capable of horizontal rotation, and when the support leg base is in the folded position, a gap is formed between adjacent support legs bases that can accommodate the arm.

[0012] In order to further solve the technical problem to be solved by this utility model, the tripod anti-collision structure provided by this utility model has a positioning structure between the anti-collision component and the tripod base.

[0013] In order to further solve the technical problem to be solved by this utility model, the present utility model provides a tripod anti-collision structure, wherein the positioning structure includes a plurality of positioning holes provided on the bottom surface of the tripod base and arranged around its center, and mounting holes provided on the top surface of the anti-collision component, wherein the mounting holes are provided with spring plungers that can cooperate with each positioning hole in sequence.

[0014] In order to further solve the technical problems to be solved by this utility model, the tripod anti-collision structure provided by this utility model is provided with a hook.

[0015] In order to further solve the technical problems to be solved by this utility model, in the tripod anti-closing structure provided by this utility model, the outer end of the stop arm (31) is provided with a guide structure, the guide structure being a chamfer or arc surface, so that the stop arm can be screwed into the anti-airway slot.

[0016] In order to further solve the technical problems to be solved by this utility model, the tripod anti-collapsing structure provided by this utility model has a retractable support leg connected to each support leg seat.

[0017] In order to further solve the technical problems to be solved by this utility model, the tripod anti-folding structure provided by this utility model has the support leg seat rotatably connected to the triangular seat and the two are provided with an unfolding angle adjustment structure.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] In this invention, the tripod's anti-collision structure uses a rotating component to lock and unlock the leg supports, effectively preventing the tripod from accidentally collapsing and improving safety and stability. The planar contact design of the limiting inclined surface and the supporting surface disperses stress, resulting in a large and even stress distribution, thus increasing structural stability. Furthermore, this anti-collision structure is simple in structure, easy to operate, accurately positioned, and multifunctional, significantly enhancing the user experience and reliability of the tripod. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, wherein:

[0021] Figure 1 This is a three-dimensional structural schematic diagram of the present invention;

[0022] Figure 2 This is an exploded view of the present invention;

[0023] Figure 3 This is a diagram illustrating the usage state when the outriggers are deployed;

[0024] Figure 4 This is a diagram showing the usage state when the outriggers are retracted. Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-4 As shown, the tripod anti-collapsing structure of this embodiment includes a tripod base 1 and three leg bases 2 that are evenly and movably connected around the periphery of the tripod base 1. Each leg base 2 is connected to a retractable leg 5.

[0027] In this embodiment, the outrigger 5 adopts a multi-section telescopic tube structure, and its telescopic state can be fixed by a locking mechanism. The locking mechanism can be a commonly used locking mechanism in the prior art, such as a lever-type locking mechanism, a knob-type locking mechanism, or a snap-locking mechanism. Figure 1 As shown, the support leg 2 is rotatably connected to the triangular base 1, and an extension angle adjustment structure is provided between the two. This extension angle adjustment structure is conventional technology and will not be described in detail here.

[0028] To prevent the tripod from accidentally collapsing while in use, this embodiment incorporates an anti-collapsing component 3 on the bottom surface of the tripod base 1. The anti-collapsing component 3 is movably connected to the bottom surface of the tripod base 1 and can move between a first position and a second position. In the first position, the anti-collapsing component 3 prevents the leg supports 2 from rotating in the collapsing direction; in the second position, the anti-collapsing component 3 releases its obstruction of the leg supports 2 and is at least partially retracted and concealed within the tripod base 1 or between the leg supports 2.

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, the anti-gathering component 3 is rotatably connected to the bottom surface of the triangular base 1 via a rotating shaft and can rotate horizontally. Three outwardly extending stop arms 31 are evenly arranged around the perimeter of the anti-gathering component 3. A limiting inclined surface 311 is provided on the lower side of the outer end of each stop arm 31, and a clearance slot 21 is provided on the inner side of the support leg base 2 to allow the stop arms 31 to screw into. A support surface 22 is provided on the lower side of the clearance slot 21, and the support surface 22 can abut against the limiting inclined surface 311 to prevent the support leg base 2 from rotating in the gathering direction.

[0030] Specifically, when the tripod is fully extended, such as Figure 3 As shown, by rotating the anti-collision component 3, the stop arm 31 can be screwed into the corresponding clearance slot 21, and the limiting inclined surface 311 at the end of the stop arm 31 abuts against the support surface 22, thereby restricting the rotation of the outrigger seat 2, thus restricting the tripod from collapsing, preventing the tripod from collapsing accidentally, and increasing safety.

[0031] The planar contact design of the limiting inclined surface 311 and the supporting surface 22 can disperse the force, with a large force-bearing area and uniform force distribution, which can increase the structural stability.

[0032] When it's time to fold up the tripod, simply continue rotating the anti-folding component 3, causing the stop arm 31 to rotate out of the corresponding clearance slot 21, releasing the restriction on the outrigger 2, and then fold up the tripod. Figure 4 As shown, when the tripod is folded up, a gap is formed between the adjacent support legs 2 that can accommodate the stop arm 31. The stop arm 31 just extends into the gap, which can prevent the stop arm 31 from interfering with the folding action.

[0033] It is worth noting that, in addition to the rotating connection structure mentioned above, the movable connection structure between the anti-gathering component 3 and the triangular base 1 can also be a rotating connection combined with a lifting mechanism. That is, the anti-gathering component 3 can not only rotate but also be lifted. The lifting mechanism is used to facilitate raising the anti-gathering component 3 into the triangular base 1 and fixing it in place using a locking structure (such as a magnetic or snap-fit ​​structure), thereby achieving the purpose of storing and hiding the anti-gathering component 3 inside the triangular base 1.

[0034] To facilitate the positioning of the anti-gathering component 3, a positioning structure is provided between the anti-gathering component 3 and the triangular base 1. Specifically, as follows... Figure 2 , Figure 4 As shown, the positioning structure includes several positioning holes 11 disposed on the bottom surface of the triangular base 1 and arranged around its center, and mounting holes 32 disposed on the top surface of the anti-gathering member 3. Each mounting hole 32 contains a spring plunger 4 that can sequentially cooperate with each positioning hole 11. In this embodiment, six positioning holes 11 are provided, corresponding to six positions of the anti-gathering member 3. These six positions actually have only two states: anti-gathering state and gathered state.

[0035] When the anti-gathering component 3 is rotated, the spring plunger 4 automatically engages in the corresponding positioning hole 11 under the action of the spring, thereby achieving positioning. It is worth noting that, in addition to accurate positioning, this positioning structure also provides a "click" sound feedback, allowing the user to determine whether the anti-gathering component 3 has been rotated into place based on the sound feedback when rotating and adjusting it.

[0036] To further enhance the stability of the tripod, the anti-collision component 3 is equipped with a hook 33. Heavy objects, such as sandbags or backpacks, can be hung on the hook 33 to further increase the tripod's stability, especially in windy conditions, effectively preventing the tripod from tipping over. Furthermore, since the hook 33 extends downwards, it also serves as a handle for adjusting the anti-collision component 3, allowing the user to easily rotate it.

[0037] To facilitate the insertion of the stop arm 31 into the clearance slot 21, preferably, the outer end of the stop arm 31 is provided with a guide structure, which can be a chamfer or an arc-shaped surface. In this embodiment, the outer end of the stop arm 31 adopts a rounded corner design so that the stop arm 31 can be screwed into the clearance slot 21.

[0038] The tripod anti-collapsing structure of this utility model has the following advantages:

[0039] 1. Simple structure: The anti-closing structure of this utility model is simple in structure, easy to manufacture and assemble, and has a low cost.

[0040] 2. Easy to operate: Users can lock and unlock simply by rotating the anti-closing component 3, making operation simple and convenient.

[0041] 3. Stable and safe: Through the cooperation of the limiting inclined surface 311 and the supporting surface 22, the force-bearing area is large and the force is evenly distributed, which can effectively prevent the tripod from being accidentally retracted, and improve the stability and safety of the tripod.

[0042] 4. Multifunctionality: The hook 33 on the anti-collision part 3 can be used to hang heavy objects, further increasing the stability of the tripod, and can also be used as an operating handle.

[0043] 5. Accurate positioning: The positioning structure can accurately position the anti-gathering component 3 to the preset position, improving the convenience and reliability of use.

[0044] The above is a description of specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art under the concept of this utility model should be included within the protection scope of this utility model.
