Connecting component for motor and peristaltic pump

Abstract

The invention discloses a connecting component for a motor and a peristaltic pump. The motor comprises a motor output shaft. The connecting component comprises a motor coupling and an upper pull pin cover. The motor coupling comprises a coupling body and a fastener used for connecting the coupling body with the motor output shaft. A connecting part is arranged at one end of the coupling body and provided with a pull pin groove. The upper pull pin cover comprises an upper pressing cover and a pull pin which are detachably connected, and the motor coupling and the upper pull pin cover are detachably connected through the pull pin and the pull pin groove. By the adoption of the connecting component for the motor and the peristaltic pump, the effect that transmission of the peristaltic pump can be achieved through the connecting component via different motors, universality is good, the standardization degree is high, and use is convenient.

Description

technical field [0001] The invention belongs to the field of connecting parts of instruments, and in particular relates to a connecting part of a motor and a peristaltic pump. Background technique [0002] Peristaltic pumps pump fluid by alternately squeezing and releasing the pump tubing. It's like squeezing a fluid-filled hose with your fingers, and the fluid in the tube moves forward as the fingers slide forward. The peristaltic pump is also based on the same principle except that the fingers are replaced by rollers. Peristaltic pumps are often used for the transportation of high-viscosity liquids, which have the advantage of accurate measurement. Because the liquid flowing in the conduit does not contact the pump body, does not generate pollution, and the flow rate is adjustable, it is suitable for use in blood collection and transfusion equipment to provide power for blood collection and retransfusion.

Problems solved by technology

[0003] In the prior art, for blood pumps used in blood collection and blood transfusion equipment, the driving motor is generally used to directly drive the pump head to rotate. In this case, the driving part must be matched with the connection part of the pump head. Unable to transfer smoothly from the drive unit to the pump head, the pump head cannot function properly and efficiently

The utility model patent with domestic publication number CN1350617A discloses a peristaltic fluid pump, which includes a rotor, a rotor shaft and a housing. The shaft part is connected with the motor by means of a coupling to make the rotor rotate during work. However, most of the couplings in the prior art use a single key connection. In this connection, the rotor of the motor or motor and the rotor of the peristaltic pump It must be able to match. When the specifications of the motor or the rotor of the motor or the specification of the rotor of the peristaltic pump are changed, the original coupling cannot bond and connect the two, and it is necessary to customize or find a coupling suitable for the specification. device, which brings a lot of inconvenience to the use
