Description

Technical Field

[0001] The utility model belongs to the technical field of peristaltic pumps, and in particular relates to a peristaltic pump which is easy to maintain. Background Art

[0002] A peristaltic pump is like squeezing a hose filled with fluid with your fingers. As the fingers slide forward, the fluid in the tube moves forward. The peristaltic pump also works on the same principle, except that the fingers are replaced by rollers. The fluid is pumped by alternately squeezing and releasing the pump's elastic delivery hose, just like squeezing a hose with two fingers. As the fingers move, negative pressure is formed in the tube, and the liquid flows.

[0003] For example, the Chinese patent with publication number CN210599356U proposes a peristaltic pump head structure, which includes a shell and a roller assembly arranged inside the shell, a photoelectric sensor is arranged inside the shell, and the photoelectric sensor has a transmitting end and a receiving end corresponding to each other, and the roller assembly is provided with a baffle at a position between the transmitting end and the receiving end, and an upper pressure block is arranged above the shell, and the upper pressure block is connected to the shell by a connecting rod, and a rotating locking device is also arranged between the upper pressure block and the shell. The utility model ensures the accuracy of the flow rate of the peristaltic pump head by ensuring the consistency of the starting position of the peristaltic pump each time; the upper pressure block and the shell are connected by a connecting rod, and a rotating locking device is arranged between the upper pressure block and the shell, which can not only ensure the stability of the connection between the upper pressure block and the shell, but also facilitate opening the upper pressure block to maintain and repair the pump head, thereby extending the service life of the pump, and has the advantages of simple structure, easy manufacturing, practicality and high efficiency;

[0004] However, in the actual application of this solution, since the pump tube is fixed inside the rotating locking device 9, the pump tube cannot be quickly disassembled, affecting the subsequent maintenance efficiency of the peristaltic pump. To solve the above problem, we propose a peristaltic pump that is easy to maintain. Utility Model Content

[0005] The utility model provides a peristaltic pump which is easy to maintain and solves the problems mentioned in the background technology.

[0018] Preferably, an adjusting groove is provided on one side inside the placement groove, and a push plate is provided inside the adjusting groove.

[0019] Preferably, a control groove is opened on one side inside the adjustment groove, an electric push rod is fixedly connected inside the control groove, and one end of the telescopic shaft of the electric push rod is fixedly connected to one end of the push plate.

[0020] The working principle and beneficial effects of the utility model are:

[0021] By setting a peristaltic tube, when the staff installs the peristaltic tube inside the placement groove, the servo motor is started. At this time, the driving shaft of the servo motor can drive the extrusion rod to rotate through the connecting block. At this time, several protrusions of the extrusion rod during the rotation can squeeze the peristaltic tube, so that the liquid inside the peristaltic tube can peristalsize. Since the peristaltic tube is movably installed inside the placement groove, it is convenient for the staff to disassemble and replace the peristaltic tube later, so as to facilitate the maintenance of the peristaltic pump later. By setting a connecting ring, since the connecting ring is threadedly connected to the connecting groove, the placement block can be fixed on one side of the installation box, and it is convenient to disassemble the placement block later. By setting a clamping block, when the clamping block and the clamping groove are movably sleeved together, the rotation of the connecting block can drive the extrusion rod to rotate through the clamping block. By setting an electric push rod, the telescopic shaft of the electric push rod can drive the push plate to move, so as to facilitate the quick pushing of the peristaltic tube out of the placement groove later, thereby improving the disassembly efficiency of the peristaltic tube.
