| description | The utility model relates to a connecting device of fire main pipes, particularly a snap type coupling for water suction pipes. The snap type coupling for water suction pipes is composed of a water suction pipe male coupling and a water suction pipe female coupling which are sealed by a V-shaped sealing ring, wherein, the outer side of the water suction pipe female coupling are provided with a pair of square holes symmetrically; the bottom of a pair of sliding seats are sheathed in the square holes; an unloading turn knob is connected with a sliding block through a screw nut; the sliding block penetrates through a spring and the sliding seats. When the unloading turn knob is rotated, under the action of the elastic force of the spring, and under the matched action of an eccentric convex rib structure on the wall top of the turn knob and the umbrella-shaped top inclined plane of the sliding seats, the sliding block is driven to move, and therefore, fire main pipes can be connected quickly or dismounted easily. |
