Abstract
The utility model discloses a locking mechanism between pin tubes of a tripod, which comprises an outer tube and an inner tube. The inner tube is fixedly connected with the outer tube through the locking mechanism; the locking mechanism comprises a connecting tube, a locking check ring and a locking sleeve; after assembly, a wedge-shaped locking face of the locking check ring is extended into an inner locking face; a conical step of the locking sleeve is supported against a compact conical surface; the locking sleeve is rotated, the locking sleeve can move axially by the screwed fit,; the locking check ring is driven to move by the fit of a convex ring and a groove; after the pin tubes are locked, the wedge-shaped locking face of the locking check ring is extruded by the inner locking face to retract inwards so that the inner tube is clamped; meanwhile, the conical step of the locking sleeve is tightly pushed against the compact conical surface so the rear end of the locking check ring is compressed and the inner tube is further clamped by the rear end of the locking check ring; moreover, the locking mechanism has a simple structure, is convenient in use and realizes an perfect locking effect.
