Abstract

The invention relates to a small roller pump comprising a pump body 1, a block 2, and a pump element 8. The body and the block are locked and opened by a positioning eccentric wheel 3, arranged on a positioning base relative to the back of the block. The distance between the body and the block is smaller than two timed eccentric distance of the eccentric wheel, the back of the block is disposed with an arc cut relative to the positioning eccentric wheel, the body combine face combined with the block is arranged with a block guiding rod (5) protruded, and the combine face of the block is disposed with relative block guiding rod hole (6), engaged with the rod (5), the block guiding rod is sheathed with a block spring (7), the roller swing support (11), swing stop rod (12) and swing spring (13) form a self-elastic space adjuster of roller to automatically adjust the space between the roller and the inner wall of the pump, and limit the minimum space. The invention has simple structure, easy production and simple operation or the like.

Description

technical field

[0001] The invention relates to a roller rolling pump, in particular to a small roller rolling pump used in medical equipment. Background technique

[0002] Roller roller pump is widely used in the human body or other fields to complete the non-polluting transportation of blood, medicinal liquid and liquid. It is a mature, reliable, high-precision, fully isolated non-polluting liquid transportation equipment. The outer wall of the soft pump tube with elastic function silicone rubber or other plastics is rolled to realize the pollution-free delivery of the liquid in the pipeline. The main structure and working principle of the roller rolling pump is: the rolling pump is composed of the pump body and the pump body slider. There is a rolling groove raceway in the pump, and the pump core assembly is supported in the groove, and the pump core assembly is mounted on the periphery. There are axial rollers, and there is a gap between the rollers and the rolling groo...
