It is composed of an air pump 200 coupled to guide the intake and exhaust of air. In other words, the carrier according to the present invention may provide an effective and smooth pumping operation by arranging the air pump 200 on the bottom of the carrier body 100, specifically, the bottom of the back of the carrier body 100.

As is well known to those skilled in the art, the carrier of the present invention is a cover case 120 connected to the body case 110 and the body case 110 to open and close the open side of the body case 110, one side open. There is a carrier body 100 consisting of a), as shown in the upper end of the carrier body 100 is provided with a handle 130 that can be gripped by the carrier. The handle 130 is inserted into the rear surface of the main body case 110, the slide shaft 131 extending downward at both ends is adjustable in a sliding manner. In addition, the carrier of the present invention arranges a plurality of casters 140 at the bottom of the carrier body 100 to facilitate the movement in contact with the ground. The caster 140 may be rotatably coupled to the bottom surface of the carrier body 100, for example, the bottom surface of the body case and / or the bottom surface of the cover case, as shown, without being limited to the size and shape of the travel carrier. It may be rotatably coupled at various sites to correspond to.

In the embodiment of the present invention, the air pump 200 is disposed at the bottom bottom of the back of the main body case 110, it is selectable between the handle 130 and the caster 140 opposite to the slide shaft 131 of the It may be arranged parallel to the axial direction. The air pump 200 is accommodated in the recess 111 formed at the bottom of the rear surface of the main body case 110. In addition, the air pump 200 may be detachably coupled to the recess 111 of the main body case or may be integrally coupled to each other.

As described above, the present invention arranges the handle 130 on the top of the back of the main body case 110 and the air pump 200 is disposed on the bottom of the bottom of the main body case 110. The air pump 200 is disposed between the pair of slide shafts 131 which assists the inflow and / or withdrawal of the handle from the main body case 110 to minimize the internal volume change of the main body case and to pump the air pump 200. It is possible to secure a reciprocating movement space of the piston rod 220 for.

Specifically, the air pump 200 is a cylinder body 210 formed in a size and shape that can be inserted into the recess 111, the interior of the cylinder body in the first pneumatic operation chamber 210a and the second pneumatic operation chamber 210b.

The operator, for example, connects the play tube, the boat, the bicycle wheel, the compression pack, etc., in fluid communication with the first intake port 211 by an extension hose (indicated by a dotted line in FIG. 2). When the worker pulls the handle 230 outward, the air charged in the internal space such as the water tube through the retraction movement of the piston rod 220 is the first intake port 211 and the inlet hole 211a of the open state Is forced into the first pneumatic operation chamber (210a) of the cylinder body 210 across the. Then, the operator forcibly opens the discharge hole 212a through the forward movement of the piston rod 220 so that the air inside the first pneumatic operation chamber 210a is discharged to the atmosphere through the first exhaust port 212. do.

In contrast, the operator connects the water tube, boat, bicycle wheel, etc. in fluid communication with the first exhaust port 212 by an extension hose (indicated by the dotted line in FIG. 2). When the operator pulls the handle 230 in the outward direction, the outside air passes through the retraction movement of the piston rod 220 and crosses the first intake port 211 and the inlet hole 211a in an open state. Suction guided to the first pneumatic operation chamber (210a). Thereafter, the operator forcibly opens the discharge hole 212a through the forward movement of the piston rod 220 to draw the air inside the first pneumatic operation chamber 210a through the first exhaust port 212 to the water play tube or the like. Forced injection
