Claim:
A dual-sectional monitor signal transmission module for Wireless Tire Pressure Monitoring Systems, the module comprising: a module body and an air tap on one side thereof, said air tap being assembled and fixed in a hole of a tire rim; wherein said module body and said air-tap are a dual-sectional piece allowing said air-tap to be fittingly snapped into the hole on the tire rim; further comprising: a mounting seat at an end of said module body where the air-tap is to be positioned so that the air-tap and an outer-end of the mounting seat can be connected in a counter-screw setup wherein the air tap is comprised of a flexible outer-sleeve and a metal tube, said outer-sleeve having on one end thereof a sunken-slot, which forms an external thread, protruding in a center of the sunken-slot at a same end of the metal tube, wherein said mounting seat is comprised of a step-shape cylindrical metal seat with a protruding tube at an outer end thereof having a threaded connection slot in a center thereof, an inner end of the mounting seat being a column-shape body, an outer side of a mid-section of the mounting seat forming a collared edge, and a slot being set at the air-tap end of the module body, wherein the mounting seat is orientable to snap into the slot of the module body through the column-shape body at the internal end and positioned by stopping the collared edge at the external part of the module body; and wherein the air-tap is fittable onto the protruding tube on the mounting seat through the sunken-slot, and the column-shape body is screwable onto the threaded connection slot on the protruding tube to achieve positioning of the air-tap on the module body.
