Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As described in the background art, the traditional liquid rolling pump has the defects of complex structure, high manufacturing cost, large integral processing difficulty and the like, and because of small volume, some pump pipes with large calibers cannot be used, and the flow rate is too small to meet the requirements of a laboratory.

In order to solve the problem, the utility model provides a liquid roller pump, include: pump body, pump core, roller 7 and motor 13.

Referring to fig. 1 and 3, the pump body includes a bottom plate 3 and a pump body housing 1, and the pump body housing 1 is fixed on the bottom plate 3 by screws. The pump body shell 1 and the bottom plate 3 are enclosed to form a pump core containing groove, and the whole pump core containing groove is U-shaped. The pump body shell 1 is provided with a pair of pump pipe grooves which are communicated with the pump core containing groove. One end of the pump pipe 8 penetrates into the pump core accommodating groove from the pump pipe groove, is attached to the inner wall of the pump body shell 1, and finally penetrates out of the other pump pipe groove. Each pump tube groove is provided with a pump tube clamp 10 for fixing the pump tube 8 relatively, and the pump tube clamp 10 can be fixed on the pump body shell 1 through screws.

The pump core is rotationally arranged in the middle of the pump core accommodating groove. Specifically, the pump core comprises a rotating shaft 5, and an upper connecting plate 6 and a lower connecting plate which are fixed on the rotating shaft 5, wherein the lower end of the rotating shaft 5 penetrates through the bottom plate 3 and is connected with the bottom plate 3 through a bearing.
