Abstract

The utility model provides a tee coupling with position limiting blocks for a water conveying hose. The tee coupling comprises a straight-through clamping pipe, a tee seat and a straight-through casing pipe, wherein a circumferential stop block is arranged on an outlet end edge of any outer clamping block of the clamping pipe; and a circumferential stop block is arranged on an outlet end edge of any outer clamping block of a tee. When the straight-through clamping pipe is clamped, rotationally connected and locked with the tee seat, a sealing piece positioned between the straight-through clamping pipe and the tee seat is pressed to deform; and when the outer clamping blocks of the clamping pipe rotate along inner clamping blocks of the tee to preset limit positions, the positions of the outer clamping blocks of the clamping pipe are limited by the circumferential stop blocks arranged on the outer clamping blocks of the clamping tube to prevent the outer clamping blocks of the clamping pipe and the inner clamping blocks of the tee from continuously slipping relatively, so that the extrusion deformation amount of the sealing piece can be controlled, the phenomenon that the sealing piece is extruded and torn because an operator applies over rotary moment when a steady sealing effect is achieved is prevented, and the phenomenon that the outer clamping blocks of the clamping pipe and the inner clamping blocks of the tee fall off because the outer clamping blocks of the clamping pipe overly rotate relative to the inner clamping blocks of the tee to be malposed cannot occur either, so that convenience of the clamping, rotational connection and the lockage and reliable sealing can be guaranteed; and the clamping, rotationally connecting and locking principle of the straight-through casing pipe and the tee seat is the same as the above.
