Description

Technical Field

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

[0002] In the structure of a tripod, the pivot column (such as the center column) is usually mounted on the base (or bowl, connecting plate) at the top of the tripod and can be raised and lowered vertically. In existing technology, especially when quickly lifting the pivot column to adjust the height, or when the main locking mechanism (such as a knob lock, lever lock, etc.) accidentally loosens or is not fully locked, there is a risk that the pivot column may be pulled excessively upwards, or even completely detached from the tripod base. Although some existing tripod pivot columns have simple limiting devices or rely on friction to prevent complete detachment, these devices are sometimes complex in structure, expensive, or inconvenient to operate when the pivot column needs to be removed for cleaning or reverse installation (for low-angle shooting), or their reliability and durability in preventing detachment still have room for improvement.

[0003] Furthermore, the lower end of irregularly shaped shafts is usually designed with or has a hook structure pre-installed. However, in current common tripod irregularly shaped shaft designs, these hooks are mostly independent components, such as those attached to the lower end of the irregularly shaped shaft body by screwing, riveting, snap-fit ​​connection, or as part of a separate cover plate assembly at the end of the shaft. This split connection method increases the number of parts, making the production and assembly process more complex and correspondingly increasing manufacturing costs. On the other hand, the connection point between the hook and the irregularly shaped shaft body may also become a weak point in the structure. Under prolonged use, frequent loading of heavy objects, or accidental large impacts, this connection point is prone to loosening, wear, deformation, or even breakage, thus affecting the reliability and load-bearing capacity of the hook.

[0004] 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

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a simple photographic tripod structure that can effectively prevent the accidental dislodgement of irregularly shaped axes.

[0006] This utility model is achieved through the following technical solution:

[0007] To solve the above-mentioned technical problems, this utility model provides a tripod anti-slip structure, comprising:

[0008] An irregular shaft; and

[0009] An anti-detachment component is movably connected to the irregular shaft. The anti-detachment component is configured to move between a retracted position and an extended position. In the extended position, the anti-detachment component extends laterally from the irregular shaft to prevent the irregular shaft from dislodging from the tripod base. In the retracted position, the anti-detachment component is received within the irregular shaft or flush with the side of the irregular shaft.

[0010] To further address the technical problem to be solved by this utility model, this utility model provides a tripod anti-slip structure in which the irregular shaft is provided with a receiving space for accommodating the anti-slip component, and the anti-slip component is slidably installed in the receiving space through a sliding connection structure to realize its movement between the retracted position and the extended position.

[0011] To further solve the technical problem to be solved by this utility model, the tripod anti-slip structure provided by this utility model includes a sliding connection structure comprising: at least one protruding ridge and at least one sliding groove, wherein at least one of the protruding ridge and the sliding groove is formed on the inner wall of the accommodating space, and the other is formed on the outer surface of the anti-slip member, and the protruding ridge and the corresponding sliding groove are slidably engaged.

[0012] In order to further solve the technical problem to be solved by this utility model, the tripod anti-slip structure provided by this utility model has two elastic arms, one of the protrusion and the other of the sliding groove, which are respectively arranged on the upper and lower side walls of the accommodating space, while the other of the protrusion and the sliding groove are respectively arranged on the corresponding elastic arm.

[0013] To further address the technical problems addressed by this utility model, the present utility model provides a tripod anti-slip structure in which the irregular shaft has a Y-shaped cross-section and includes three radially extending and circumferentially evenly distributed ribs; the anti-slip component has a Y-shaped profile that matches the Y-shaped cross-section of the irregular shaft.

[0014] In order to further solve the technical problem to be solved by this utility model, in the tripod anti-slip structure provided by this utility model, the free end of the elastic arm is provided with an arc-shaped transition surface or a chamfer.

[0016] In order to further solve the technical problems to be solved by this utility model, the tripod anti-slip structure provided by this utility model has the hook and the irregular shaft as an integrally formed structure.

[0017] In order to further solve the technical problem to be solved by this utility model, in the tripod anti-slip structure provided by this utility model, the top view projection of the hook falls into the cross section of the irregular shaft.

[0018] To further address the technical problems addressed by this utility model, a tripod anti-slip structure is provided, wherein the irregular shaft has a Y-shaped cross-section and includes three radially extending and circumferentially evenly distributed ribs; the hook includes at least one hook portion and at least one connecting portion, wherein the hook portion is formed by opening a notch in one of the ribs, and the connecting portion is formed by the lower ends of the other two ribs.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] First, an anti-detachment component was designed that is movably connected to the lower part of the irregular shaft. This anti-detachment component can switch between extended and retracted positions, effectively preventing the irregular shaft from accidentally detaching from the tripod base and improving safety during use.

[0021] Secondly, the traditional split hook structure is innovatively integrated with the irregular shaft. Especially when using a Y-shaped cross-section irregular shaft, the hook can be directly formed using the rib plate structure, making the hook not only sturdy and durable with reliable load-bearing capacity, but also more compact and with lower production costs.

[0022] In summary, through these structural improvements, this utility model provides a simple, safe, reliable, easy-to-use, and highly integrated photographic tripod structure, which significantly improves the user experience and overcomes the shortcomings of existing technologies.

[0028] 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.

[0029] Please see Figures 1 to 4 This embodiment provides a tripod anti-slip structure. The photographic tripod structure mainly includes an irregularly shaped axis 1 and an anti-slip component 2. This structure is primarily applicable to the center column of a tripod (i.e., the irregularly shaped axis 1 is the center column). Of course, besides being applicable to the center column of a tripod, this structure is also applicable to other tripod structures, such as the legs.

[0030] The irregular shaft 1 is the core lifting component of the tripod. In this embodiment, the cross-section of the irregular shaft 1 is preferably designed as Y-shaped (also known as herringbone or triangular star shape), specifically composed of three radially extending ribs 13 evenly distributed at approximately 120 degrees from the central region. This Y-shaped cross-section design provides excellent bending and torsional resistance, making the irregular shaft more stable. Of course, in other embodiments, the irregular shaft 1 can also be circular, square, or other polygonal cross-sections, but the Y-shaped cross-section exhibits unique advantages in this embodiment.

[0031] The anti-slip element 2 is movably connected to the lower part of the irregular shaft 1. Here, "lower part" refers to the end of the irregular shaft closest to the ground when it is mounted on the tripod base. The anti-slip element 2 is preferably made of engineering plastics (such as ABS, PC, nylon, etc.) or lightweight metal materials with a certain strength and elasticity. The anti-slip element 2 is configured to move between a retracted position and an extended position.

[0032] Specifically, when the irregular shaft 1 needs to pass through the tripod base (not shown) or requires significant height adjustment, the anti-slip component 2 can be placed in the retracted position. In this position, the anti-slip component 2 is fully contained within the outline of the irregular shaft 1, or is basically flush with the side of the irregular shaft 1, and will not interfere with the smooth movement of the irregular shaft.

[0033] When the user wishes to prevent the irregular shaft 1 from being accidentally pulled completely upwards from the tripod mount (e.g., during a rapid height adjustment or when the locking mechanism is not fully engaged), the anti-slip member 2 can be moved to the extended position. In the extended position, at least a portion of the anti-slip member 2 extends from one or more sides of the irregular shaft 1, forming one or more stops that extend beyond the original cross-sectional profile of the irregular shaft 1. These stops physically abut against the edge of the hole in the tripod mount for mounting the irregular shaft or a specific limiting structure, thereby effectively preventing the irregular shaft 1 from continuing to move upwards and detaching from the tripod mount, thus avoiding the risk of damage to photographic equipment that may result from the irregular shaft accidentally detaching. This invention achieves an effective anti-slip function through the simple anti-slip member 2, improving the safety of use.

[0034] To achieve the aforementioned functional movement of the anti-detachment component 2, a receiving space 11 for accommodating the anti-detachment component 2 is provided at the lower part of the irregular shaft 1. The shape and size of the receiving space 11 are adapted to the shape of the anti-detachment component 2. The anti-detachment component 2 is slidably installed in the receiving space 11 through a sliding connection structure, thereby enabling it to switch between a retracted position and an extended position.

[0035] In this embodiment, the sliding connection structure is specifically manifested as follows: at least one protruding ridge 12 is formed on the inner wall of the receiving space 11, and correspondingly, at least one sliding groove 21 is formed on the outer surface of the anti-detachment member 2. Alternatively, the positions of the protruding ridge 12 and the sliding groove 21 are interchanged, with the protruding ridge 12 located on the anti-detachment member 2 and the sliding groove 21 located on the inner wall of the receiving space 11 (the same applies below). The protruding ridge 12 and the corresponding sliding groove 21 slide in cooperation. Guided by the protruding ridge 12 within the sliding groove 21, the anti-detachment member 2 can stably and linearly reciprocate along a predetermined path. In a preferred design, two or more sets of symmetrically distributed protruding ridges 12 and sliding grooves 21 can be provided to enhance the stability of the connection and the feel of sliding. For example, protruding ridges 12 can be provided on the inner walls of opposite sides of the receiving space 11, and sliding grooves 21 can be provided on the corresponding side surfaces of the anti-detachment member 2. Of course, the positions of the protruding ridge 12 and the sliding groove 21 can also be interchanged.

[0036] Considering the Y-shaped cross-sectional characteristics of the irregular shaft 1, the top view of the anti-detachment member 2 or the outline of its main part is preferably designed to be Y-shaped to match the Y-shaped cross-section of the irregular shaft 1 (or the internal outline of its receiving space 11). This means that the anti-detachment member 2 can be better embedded in the internal structure of the irregular shaft 1, making the overall structure more compact. Furthermore, the extending direction of the protruding ridge 12 and the sliding groove 21 (i.e., the sliding direction of the anti-detachment member 2) is preferably designed to be parallel to the width direction of one of the ribs 13 of the irregular shaft 1 (i.e., approximately perpendicular to the length direction of the rib 13, or radially outward or inward along a branch of the Y-shape).

[0037] To facilitate the operation of the anti-slip component 2 and potentially provide a self-locking or positioning function, the anti-slip component 2 can be designed with an elastic structure. For example, the anti-slip component 2 may include two elastic arms 22 (here, "upper and lower" refers to the structure of the anti-slip component itself, and can also be understood as two or more elastic parts arranged opposite each other). The protruding ridges 12 can be respectively provided on the upper and lower opposite side walls of the receiving space 11, while the sliding grooves 21 are respectively formed on the corresponding elastic arms 22. When the anti-slip component 2 slides, the elastic arms 22 can undergo slight elastic deformation, for example, deforming and recovering when passing a certain limiting point (which may be a specific shape of the protruding ridge or a concave point in the sliding groove), thereby providing a sense of segmentation or positioning, so that the anti-slip component 2 can be stably maintained in the extended or retracted position.

[0038] To further optimize sliding performance, reduce operating force, and prevent jamming, the free end of the elastic arm 22 may have an arc-shaped transition surface 221 or be chamfered. This design facilitates the assembly of the anti-detachment component 2.

[0039] In addition to the aforementioned anti-slip function, the irregular shaft structure of this utility model also integrates a hook function. For example... Figure 1 and Figure 4 As shown, the lower end of the irregular shaft 1 is provided with a hook 14. This hook 14 is used to hang heavy objects (such as camera bags, sandbags, etc.) to increase the overall weight of the tripod, lower the center of gravity, and thus improve stability in windy environments or when using telephoto lenses.

[0040] A significant improvement lies in the fact that the hook 14 and the irregular shaft 1 are integrally molded. This means that the hook 14 is not later attached to the irregular shaft 1 through screws, riveting, welding, or clips, but is formed in one step during the manufacturing process, such as through metal die casting, plastic injection molding, or directly on the irregular shaft tube through processes such as cutting and bending. The integrally molded hook has higher structural strength and durability, avoiding problems such as loosening and breakage that may occur at the connection points of traditional split hooks, and its load-bearing capacity is also more reliable. At the same time, this also reduces the number of parts and simplifies the assembly process.

[0041] In order to prevent the hook 14 from easily snagging on surrounding objects when not in use, and to maintain the overall aesthetics and compactness of the irregular shaft, the top view projection of the hook 14 is preferably designed to fall completely within the Y-shaped cross-sectional profile of the irregular shaft 1.

[0042] Specifically, regarding the formation of the hook 14, this embodiment utilizes the Y-shaped rib plate 13 structure of the irregular shaft 1. The hook 14 includes at least one hook portion 141 and at least one connecting portion 142. The ingenious aspect lies in the fact that the hook portion 141 is formed by creating a notch or partially bending the lower end region of one of the three rib plates 13 of the irregular shaft 1, thus forming a hook that can be practically used for suspension. The connecting portion 142 is formed by the natural extension and convergence of the lower ends of the other two rib plates 13, or by the lower ends of all three rib plates forming a solid base, providing strong support for the hook portion 141. This design fully utilizes the structural characteristics of the irregular shaft itself, achieving a high degree of integration of the hook function.

[0043] A brief description of its working principle and usage:

[0044] When installing or removing the irregular shaft, the user can operate the anti-slip component 2 to retract it, allowing the irregular shaft 1 to smoothly pass through the mounting hole of the tripod base. Once the irregular shaft is installed, the user can push the anti-slip component 2 to the extended position; the extended portion will act as a limit, preventing the irregular shaft from accidentally slipping upwards. When increased tripod stability is required, heavy objects can be suspended directly from the one-piece hook 14. Since the hook 14 and the irregular shaft 1 are a single unit, the user need not worry about the reliability of the connection.

[0045] In summary, the tripod anti-detachment structure provided by this utility model effectively prevents the irregular shaft from accidentally detaching by setting anti-detachment components, thus improving the safety of use. At the same time, the hook is integrally formed with the irregular shaft and the hook is formed by using a Y-shaped cross-section rib plate structure. This not only makes the structure sturdy and durable, but also compact and reasonable in design, improving the overall performance of the product and the user experience.
