Straight line puts tubular type peristaltic pump
Technical field
The present invention relates to a kind of pump, definite is a kind of peristaltic pump.
Background technology
Flexible pipe of the peristaltic pump just as being full of fluid with finger pinching one, as finger forward slip tube fluid is to reach
It is dynamic.Peristaltic pump is also that this principle simply instead of finger by roller.
If China Patent No. is disclosed in 201420593526. 0 patent document《Peristaltic pump》(Authorization Notice No. is:
CN 204152766 U), existing germ collector peristaltic pump include housing, housing be provided with hose clamp and roller assembly, roller
Assembly includes the drive device that rotating disk and driving rotating disk are rotated, be provided with the edge of rotating disk it is circumferentially arranging, can freely turn
Dynamic roller, hose clamp is located at rotating disk side, and hose clamp includes movable clamping block, and movable clamping block is installed in using pivot
On housing, movable clamping block has the first pinching end and the second pinching end, and the first pinching end of movable clamping block and second clamp
Corresponding matching has one to fix to clamp block, the first pinching end and the second pinching end and the corresponding geometrical clamp of movable clamping block respectively at end
Tight block cooperatively forms retractable clamp port, and two fix to clamp block single part is integrally formed, and have between two clamp ports
The working chamber of indent, fixing to clamp has the opening stretched into for roller in the working chamber between block, and movable clamping block is to fixation
Gripping block is close and is locked through locking piece, and realization grips flexible pipe, and flexible pipe is partially passed through between being clamped fixed two ends
Working chamber, with the rotation of rotating disk, roller can serially enter squeezing tube in working chamber and realize that liquid is transmitted.
But there is following defect in existing peristaltic pump:1st, due to peristaltic pump small volume, installing space is limited, therefore movable clamping
Block needs tight fit with fixing to clamp block, and the swing angle of movable clamping block is smaller, when movable clamping block is opened, activity folder
The tight notch formed between block and rotating disk is arc line shaped, and the structure design of movable clamping block is unreasonable in addition, and flexible pipe is curved
Under curved state, flexible pipe is not easy positioning, and when flexible pipe changes the outfit, flexible pipe, which is pre-bent, to be caught in fixes to clamp at block, then will live
To fixing to clamp, block is close to grip flexible pipe to dynamic gripping block;Cause flexible pipe to change the outfit operation inconvenience, and changed the outfit process in flexible pipe
In easily by flexible pipe scratch or crush.
2nd, movable clamping block is operated using manual locking, operation inconvenience.
3rd, without changing protection of pipe, there is the improper risk for causing hose fracture of artificial maloperation.
The content of the invention
Objects of the present invention:To overcome the defect that prior art is present, the present invention provides a kind of compact conformation, activity folder
Under tight block folding position there is flexible pipe straight line to load space, realize that flexible pipe straight line puts pipe, flexible pipe replacement operation conveniently, safely compacted
Dynamic pump.
To achieve the above object, the invention provides following technical scheme:A kind of straight line puts tubular type peristaltic pump, includes shell
