This utility model discloses a vacuum resin injection distributor for wind turbine blades, comprising a main pipe, a disassembly pipe, and a connecting pipe. Lug 1 and Lug 4 are fixedly connected to the main pipe, and a plug is fixedly connected to Lug 1. A rubber sleeve is provided around the plug. Lug 2 and Lug 3 are fixedly connected to the disassembly pipe, and rubber columns are movably connected inside Lug 3 and Lug 4. A connecting plate is fixedly connected to one end of each rubber column, and a hexagonal ring is installed on the rubber column. A connector is fixedly connected to the hexagonal ring. By designing the distributor as a split type, the main pipe and the disassembly pipe can be disassembled and assembled separately, thus avoiding the need to replace the entire distributor due to blockage or aging. This effectively saves costs and resources, while also facilitating the cleaning of the resin inside the distributor. This avoids the problems associated with replacement and cleaning caused by the current one-piece design of distributors, improving practicality. This device solves the problem of current closed-type distributors.
