Portable x-ray system with a cableless collimator connection structure

A portable X-ray system equipped with an X-ray tube mounted on one end portion of the photography stand with a structure extending to a predetermined height and changing a photographing direction and a photographing angle in a portable body moved by an operator to change an installation location, the portable X-ray system comprising:

• a body (110) mounted on one end portion of the photography stand and configured to change the photographing angle and form an exterior of the X-ray tube;
• a collimator (120) mounted on one side surface of the body (110) and configured to adjust an X-ray photographing area and an X-ray photographing direction;
• and
• a rotating connection part (130) mounted between the body (110) and the collimator (120) and configured to couple the collimator (120) to be rotated based on one side surface of the body (110) and transmit power and an electrical signal transmitted from the body (110) to the collimator (120),
• wherein the rotating connection part (130) includes:
• a first coupler (131) which has a cylindrical structure formed to protrude from a center of one side surface of the body (110) by a predetermined height and has a structure that rotates in place based on one side surface of the body (110) and in which a plurality of fastening holes (135) through which coupling fasteners (136) are bolt-coupled are formed to be spaced at a predetermined angle along an outer circumferential surface of the first coupler (131);
• a second coupler (132) with a ring structure which is formed to protrude from a center of one side surface of the collimator (120) by a predetermined height and which is mounted in a form that surrounds an outer circumferential surface of the first coupler (131) to be rotated together with the first coupler (131);
• a first connection terminal (133) which is mounted at a center inside the first coupler (131) and has a pogo pin structure protruding to a predetermined height and which is provided as a plurality of first connection terminals (133) mounted to be spaced at different radii based on the center inside the first coupler (131) and connected to a second connection terminal (134) to transmit power and electrical signals to the collimator (120);
• a second connection terminal (134) which is mounted at a center inside the second coupler (132) and provided as a plurality of second connection terminals (134) in a slip ring structure in which the plurality of second connection terminals (134) are mounted to be spaced at different radii based on the center inside the second coupler (132) and which accommodates the power and the electrical signals transmitted from the first connection terminals (133);
• and
• a coupling fastener (136) which is provided as a plurality of coupling fasteners (136) mounted to be spaced at a predetermined angle along an outer circumferential surface of the second coupler (132) and has a structure bolt-coupled to the fastening hole (135) of the first coupler (131) to fasten the second coupler (132) to the first coupler (131).
