Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that when the split-type central axis structure on the tripod in the prior art needs to be connected as a whole, due to the lack of an alignment structure, it is easy to dislocate when connecting, and it is very inconvenient to use. Provides an easy-to-use detachable bottom bracket that can be connected without misalignment

Embodiment Construction

[0036] In the following, the present invention will be further described by using the following embodiments in conjunction with the accompanying drawings.

[0037] Such as Figure 1-3As shown, a detachable central axis used on a photography tripod described in this embodiment includes a first sub-axis 1, a second sub-axis 2 detachably connected to the first sub-axis 1, and a pair of A quasi-combination structure and a connection structure; the alignment-combination structure includes a joint part and a mating joint part, which are respectively arranged on the first sub-axis 1 and the second sub-axis 2, and between the joint part and the When the mating joint is combined, the first split shaft anti-rotation groove 46 formed axially on the first split shaft and the second split shaft anti-rotation groove 47 on the second split shaft are just aligned with each other, forming A straight line; the connection structure detachably connects the aligned first sub-axis 1 and the second...

Abstract

A detachable central shaft used on tripods, which is disclosed by the invention, comprises a first subshaft, a second subshaft, an aligning and combining structure and a connecting structure, and the second subshaft is detachably connected with the first subshaft; the aligning and combining structure comprises a combining part and a matched combining part, which are respectively arranged on the first subshaft and the second subshaft, and moreover, when the combining part is combined with the matched combining part, rotation-stopping grooves which are respectively axially formed on the first subshaft and the second subshaft are just aligned with each other to form a straight line; and the first subshaft and the second subshaft which are aligned are detachably connected together through the connecting structure. The arrangement of the aligning and combining structure in the detachable rotation-stopping central shaft used on tripods can ensure that the central shaft with the rotation-stopping grooves can be detachably connected and that the subshafts can be prevented from being misaligned when being connected, and moreover, the detachable central shaft is easy and convenient to use.

Description

technical field [0001] The invention relates to a photographic equipment, in particular to a detachable central axis used on a photographic tripod. Background technique [0002] Usually, skill shooting in daily life is inseparable from the help of a tripod or a monopod. The function of a tripod cannot be ignored whether it is for professional users or amateur users. Its main function is to stabilize the camera. The central axis in the prior art tripod is usually integrally formed. In order to facilitate the adjustment of the shooting angle of the photographic equipment on the tripod, the central axis is generally set longer, and the longer central axis cannot realize low-angle shooting. [0003] In order to solve the above problems, Chinese patent document CN201425694Y discloses a combined photography tripod, which includes three legs, a load plate, a leg connector and a central axis, the central axis is arranged between the load plate and the leg connector, and consists of ...
