Description
Technical Field
The invention relates to the technical field of peristaltic pumps, in particular to a linkage mechanism for opening and closing a clamping hose, a peristaltic pump head and a peristaltic pump.
Background
Peristaltic pumps are widely used in life sciences, bioscience, medicine and other fields. Peristaltic pump is a special volumetric pump, mainly applied to the distribution or transportation of fluid. When the peristaltic pump head works, the roller rotates, a section of pump pipe between the two rollers forms a pillow-shaped fluid, and the fluid is pumped by alternately extruding and releasing the elastic conveying hose of the pump; the volume of the pillow influences the flow; the rotational speed of the roller also affects the flow. The working characteristics are that the hose is extruded in the running process of the pump head, and the hose is pressed and released through the elasticity of the hose so as to achieve the purpose of fluid transmission.
When the existing peristaltic pump head is designed, the upper pipe clamp is generally fixed on the integral pressing block, and the pipe clamp moves up and down along with the integral pressing block, so that no relative displacement exists between the upper pipe clamp and the integral pressing block or the upper pipe clamp needs to be manually pulled to move along the integral pressing block to increase the distance between the upper pipe clamp and the lower pipe clamp. The integral pressing block is driven by an eccentric shaft mechanism in a pump head of the peristaltic pump to move up and down, and the eccentric distance of 2 times of the eccentric wheel in the eccentric shaft mechanism is the up-and-down movement displacement of the integral pressing block and the upper pipe clamp. When the peristaltic pump head is used for replacing the hose, the integral pressing block and the upper pipe clamp are fixed into a whole, and the space between the upper pipe clamp and the lower pipe clamp is fixed in size (equal to 2 times of the eccentric distance of the eccentric wheel). The eccentricity is the distance between the center of the connecting shaft mounting hole on the eccentric wheel and the center of the eccentric wheel.
Due to the limitation of the overall size of the peristaltic pump head, the size of the eccentric wheel is limited, so that when the hose is replaced, the space between the upper pipe clamp and the lower pipe clamp is narrow, the operation is inconvenient, and if the upper pipe clamp needs to be manually pulled, especially for replacing a hose with a large pipe diameter, the operation of pulling the pipe clamp by one hand and replacing the hose by the other hand is very inconvenient.
