Description

Technical Field

[0001] The invention relates to the technical field of double-head peristaltic pumps, in particular to a double-head peristaltic pump provided with an assembly support structure. Background Art

[0002] The double-head peristaltic pump drives the pump heads to work simultaneously through the two ends of the motor, and cooperates with the support frame to stably support the double-head peristaltic pump, making it easy to use in the corresponding working position. However, the existing double-head peristaltic pump still has some defects during assembly.

[0003] In the prior art, the authorized publication (announcement) number: CN214221457U is titled "An Easy-to-install Peristaltic Pump Head." The utility model discloses an easy-to-install peristaltic pump head, comprising a pump head body, a pump head support, a hose, and a roller. The utility model employs the above-mentioned structure to provide an easy-to-install peristaltic pump head. The hose is inserted into the gap between the V-shaped plate and the plug-in slot, and the clamping force between the V-shaped plate and the plug-in slot is adjusted according to the hardness of the hose via a key-operated member. This makes it suitable for hoses of different hardnesses, facilitates adjustment, and ensures good hose fixation, preventing the hose from slipping during use.

[0004] During the operation of the above-mentioned device, the wrench is pulled to move the pressure block 3 away from the pump head support 2, and the hose 4 is placed between the pressure block 3 and the roller 21. The wrench is pulled to move the pressure block 3 toward the pump head support 2... The limit rod 10 is inserted into the limit groove 9, and the hose 4 is fixed in the V-shaped plate 6 and the plug-in groove. It is easy to assemble and fix the tube, and there is no tube running. However, the support structure set during use is not convenient for nesting the peristaltic pump as a whole, which easily causes the peristaltic pump to vibrate and shift during use, and it is not convenient to quickly assemble and support the pump body.

[0005] In the prior art, the "Peristaltic Pump Fixture" in the authorized publication (announcement) number CN208696689U discloses a peristaltic pump fixture. The horizontal plate is provided with second raised edges on both sides, and the distance between the second raised edges corresponds to the radial width of the peristaltic pump body. The vertical plate is provided with an opening in the middle corresponding to the output end of the motor. This utility model solves the problem of difficult assembly and installation of conventional peristaltic pumps and motors.

[0006] During the operation of the above-mentioned device, the second raised edge provided on the horizontal plate is provided corresponding to the radial width of the peristaltic pump body, so that when installed, the peristaltic pump body is placed on the upper surface of the horizontal plate... The output end of the motor extends from the opening, so that the motor only has the freedom of horizontal movement, and then a transmission component is provided at the output end of the motor; simple and efficient assembly between the motor and the peristaltic pump is achieved, but when in use, the set horizontal plate is difficult to stably support and fix the pump body, and cannot be quickly removed. Summary of the Invention
