Tire assembling device

A tire assembling device, which is for installing a tire on a rim, the tire assembling device comprising:

• a main body having a top surface located on a top side of the main body;
• a holding portion extended from one side of the main body toward a reference direction;
• an abutting surface located at another side of the main body and for abutting against a rim surface of the rim;
• a guiding portion located at one end of the main body, the guiding portion comprising a first pulley pivotally connected to the end of the main body via a first axis;
• a hook portion located between the abutting surface and the top surface, wherein the hook portion is for hooking a first edge of the rim and has a side surface;
• and
• a pressing portion disposed at the main body and located between the hook portion and the guiding portion, the pressing portion comprising a second pulley pivotally connected to the main body via a second axis which is perpendicular to the first axis, the pressing portion for providing a force, wherein a direction of the force is parallel to a normal direction of the abutting surface;
• wherein when the tire assembling device is hooked on the first edge of the rim by the hook portion and is moved toward a predetermined direction along the first edge, the guiding portion guides a tire bead of the tire toward a radial direction of the rim, the pressing portion pushes the tire bead toward the normal direction of the abutting surface to guide the tire to be installed on the rim, the second pulley is touched to the tire bead at a touching point, and a tangential plane of the touching point is aligned with the side surface.
