Adapter, nozzle structure, assembly consisting of the adapter and the nozzle structure and the assembling method thereof

An assembly used in windscreen wipers, comprising:

• an adapter used for connecting and securing a nozzle structure and comprising a first adapter assembling feature and a second adapter assembling feature,
• the nozzle structure having a body, a nozzle extending from the body, a first nozzle structure assembling feature and a second nozzle structure assembling feature,
• wherein the first adapter assembling feature and the first nozzle structure assembling feature are matched with each other to form a first connection in the form of pin and a circular aperture, between the adapter and the nozzle structure, and the nozzle structure and the adapter are rotatably pre-assembled together when they are connected only by the first connection,
• wherein the second adapter assembling feature and the second nozzle structure assembling feature are matched with each other to form a second connection in the form of a snap fit between the adapter and the nozzle structure, and
• wherein the nozzle structure is secured to a side wall of the adapter by the first connection and the second connection, and
• wherein the nozzle structure further comprises a stopping block extending from the body or the nozzle of the nozzle structure, and at least a portion of the stopping block is parallel with the body of the nozzle structure, such that a portion of the side wall of the adapter is sandwiched between the stopping block and the body of the nozzle structure when the nozzle structure and the adapter are assembled together.
