Description

Foldable photographic tripod

Technical Field

Background

At present, a foldable photographing tripod is widely used in self-photographing and photographing of photographing equipment (mobile phones or cameras and the like) by people, can be supported on a plane and can stretch out and draw back at will within a certain length range, and a user can photograph by only arranging the photographing equipment on a telescopic photographing support, so that the user can photograph by holding the photographing equipment in a hand and can photograph by supporting the photographing equipment on the plane.

Existing collapsible photography tripods generally include: cell-phone presss from both sides, telescopic link, folding handle and mount pad, and the cell-phone is pressed from both sides and is installed in the upper end of telescopic link, and the mount pad cover is established in the lower extreme of telescopic link, and folding handle installs on the mount pad. When the handheld tripod shoots, the folding handle is in a folding state; when the tripod needs to be vertically arranged for shooting, the folding handle is unfolded to form a tripod bracket state. In order to further reduce the occupied space, the telescopic rod can slide relative to the mounting seat to further retract to the middle of the folding handle, so that the axial length of the tripod is further reduced. The existing telescopic rod and the mounting seat are locked through elastic deformation (an axial opening is formed in the mounting seat so that the lower end of the telescopic rod is in interference fit with the mounting seat), so that the stretching state of the telescopic rod during handheld shooting is kept. But this kind of structure, the bearing when equipment is shot to the load is low, and after using repeatedly, the dynamics is not enough, decay is fast, and telescopic link rocks greatly.
