Description

Tripod anticreep structure Technical Field The utility model relates to the technical field of photographic tripod accessories, in particular to a tripod anti-falling structure. Background In the tripod structure, a special-shaped shaft (such as a central shaft (or called a central column)) is usually mounted on a base (or called a bowl seat or a connecting disc) at the top of the tripod and can be lifted and lowered in a vertical direction. In the prior art, especially when the special-shaped shaft is quickly pulled to adjust the height, or when the main locking mechanism (such as knob locking, spanner locking and the like) is accidentally released or is not completely locked, there is a risk that the special-shaped shaft is excessively pulled upwards, and even completely released from the tripod base. Although some simple limiting devices are arranged on the special-shaped shafts of the prior tripod or the special-shaped shafts are prevented from being completely separated by friction, the devices are sometimes complex in structure and high in cost, or are inconvenient to operate when the special-shaped shafts are required to be specially removed for cleaning and maintenance or are reversely installed (to realize low-angle shooting), or the reliability and durability of the special-shaped shafts still have room for improvement. In addition, the lower end of the profile shaft is typically designed or reserved with a hooking structure. However, in the tripod profile shaft designs commonly found today, such hooks are mostly separate components, e.g. attached to the lower end of the profile shaft body by screwing, riveting, snap-fitting or as part of a separate cover plate assembly at the end of the profile shaft. On the one hand, the split type connecting mode increases the number of parts, so that the production and assembly process is more complex, and the manufacturing cost is correspondingly increased, on the other hand, the connecting point of the hook and the special-shaped shaft main body can become a weak link on the structure, and when the hook is used for a long time, heavy objects are frequently mounted or the hook is accidentally subjected to larger impact force, the connecting point is easy to loose, wear, deform and even break, thereby influencing the use reliability and the bearing capacity of the hook. Accordingly, there is a need for further improvements and refinements of the prior art to overcome these shortcomings, and the present utility model is based on this circumstance. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides a photographing tripod structure which has a simple structure and can effectively prevent a special-shaped shaft from accidentally falling out. The utility model is realized by the following technical scheme: in order to solve the technical problems, the utility model provides a tripod anti-falling structure, comprising: A contoured shaft, and The anti-falling piece is movably connected with the special-shaped shaft and is configured to move between a retracted position and an extended position, when in the extended position, the anti-falling piece extends out of the side direction of the special-shaped shaft so as to prevent the special-shaped shaft from falling out of the tripod seat, and when in the retracted position, the anti-falling piece is contained in the special-shaped shaft or is flush with the side surface of the special-shaped shaft. In order to further solve the technical problem to be solved, the utility model provides the tripod anti-falling structure, wherein the profiled shaft is provided with an accommodating space for accommodating the anti-falling member, and the anti-falling member is slidably arranged in the accommodating space through a sliding connection structure so as to realize the movement between the retracted position and the extended position. In order to further solve the technical problem, the utility model provides the tripod anti-falling structure, which comprises at least one rib and at least one chute, wherein at least one of the rib and the chute is formed on the inner wall of the accommodating space, the other is formed on the outer surface of the anti-falling piece, and the rib is in sliding fit with the corresponding chute. In order to further solve the technical problem to be solved, in the tripod anti-falling structure provided by the utility model, the anti-falling part is provided with an upper elastic arm and a lower elastic arm, one of the convex rib and the sliding groove is respectively arranged on the upper side wall and the lower side wall of the accommodating space, and the other of the convex rib and the sliding groove is respectively arranged on the corresponding elastic arm. In order to further solve the technical problem to be solved, the tripod anti-falling structure provided by the utility model has the advantages that the special-shaped shaft is provided w
