Title:
TUBE PUMP
Document Type and Number:
WIPO Patent Application WO/2018/221767
Kind Code:
A1
Abstract:
Provided is a tube pump capable of maximizing the efficiency of fluid transfer while maintaining stability with minimum load generation by enabling operation rods, which are operated so as to transfer fluid, to carry out lateral motion instead of wave-like motion through lifting method, the tube pump comprising: a main body housing; a support shaft provided such that both ends thereof are fixed to the inner lower portion of the main body housing; a drive shaft having a plurality of eccentric cams mounted at uniform intervals; a fixing shaft of which a tube having a flexibility from outer surface is inserted thereinto such that the both ends of the fixing shaft are fixed together with the tube; and a plurality of operation rods: which is rotatably inserted and fixed in the lower portion of the support shaft; and in which the plurality of eccentric cams are inserted and fixed together with each of bearings at the upper side of the support shaft so as to transfer the fluid while being sequentially moved, on the basis of the support shaft, to the left and right together with a rotation of the eccentric cams.
