Abstract
The utility model discloses a locking mechanism for a telescopic pipe, which matches with an outer pipe and an inner pipe that is looped slidingly in the outer pipe. The utility model comprises a fixed sleeve whose outside is provided with male threads and that is fixed on the upper end of the outer pipe; a rotary sleeve whose inside is provided with female threads and is fixed on the outside of the fixed sleeve; at least two locking casing sleeves that can rotate but can't move relative to each other and are connected with the inside of the rotary sleeve. The outside of each locking casing sleeve is a cone that is bigger up and smaller down. The two locking casing sleeves are plugged tightly between the outside of the inner pipe and the inside of the fixed sleeve. For the locking mechanism in the utility model, rotating the rotary sleeve will drive the locking casing sleeves to move downward relative to the outer pipe. As the locking casing sleeves are conic, when the locking casing sleeves move downward relative to the outer pipe, the locking casing sleeves will hold tightly the inner pipe inward. The locking casing sleeves are plugged tightly between the outside of the inner pipe and the inside of the fixed sleeve, they will not automatically loose the locking mechanism, so the locking performance is high.
