A hexagonal groove 221 is formed on the side of the connecting buckle 22 away from the motor 1. A center hole 231 is formed through the center of the pump seat 3. The lower surface of the seat 3 is penetrated by two sets of pipe grooves 32 for installing the inlet and outlet ends of the rubber hose 9. The pump cover 4 is detachably buckled on the outside of the pump seat 3. The center of the pump cover 4 is penetrated by a center hole 3 41. The lower surface of the pump cover 4 is penetrated by a notch 42 for accommodating the inlet and outlet ends of the rubber hose 9. The inner rotation of the center hole 2 31 and the center hole 3 41 is connected to the shaft 5. The end of the shaft 5 close to the connecting buckle 22 is fixedly connected to a hexagonal head 51 that matches the hexagonal slot 1 221. The hexagonal head 51 is located at the rear of the pump seat 3 and is movably plugged in. Inside the hexagonal groove 221, a rotating disc 6 is fixedly sleeved on the outer side of the shaft 5. The rotating disc 6 is located inside the pump base 3. Three groups of guide grooves 61 are opened in an annular equidistant array on the surface of the rotating disc 6. A roller group 7 is slidably connected to the guide groove 61. The rear side of the rotating disc 6 is connected to an adjustment component 8 for driving the three groups of roller groups 7 to move synchronously toward the center of the rotating disc 6. The rear side of the pump base 3 is connected to a main connection limiter 10, and the front side of the U-shaped support base 2 is connected to a secondary connection limiter 11. The main connection limiter 10 includes multiple groups of limit columns 101. Multiple groups of limiting columns 101 are fixed in a circular equidistant array on the rear side of the pump seat 3, and the auxiliary connecting limiting member 11 includes multiple groups of limiting sleeves 111.

Between the two adjacent groups of guide grooves 61 and on the front side of the rotating disc 6, an arc plate 62 is fixedly connected to provide a limit for the rubber hose 9. The rubber hose 9 is located between the arc plate 62 and the outer edge of the pump seat 3.

[0030] The present invention facilitates assembly and disassembly of the rubber hose 9 by providing an adjustment assembly 8. When the rubber hose 9 needs to be removed or replaced, the adjustment assembly 8 is simply used to synchronously move the three roller assemblies 7 toward the center of the rotating disk 6, freeing the rubber hose 9 from the pressure of the roller assemblies 7 and allowing for easy removal. After replacing the new rubber hose 9, the adjustment assembly 8 is then used to reset the three roller assemblies 7, resuming their compression of the rubber hose 9.

[0032] Specifically, when the plurality of limiting columns 101 and the plurality of limiting sleeves 111 are plugged in one by one, the pump base 3 and the U-shaped support base 2 are in a relatively fixed state, at this time, the motor 1 drives the shaft rod 5, the rotating disc 6 and the roller group 7 to rotate through the output shaft and the connecting buckle 22, so that the fluid in the rubber hose 9 is transported. In addition, the direction of the inlet and outlet of the rubber hose 9 in the utility model can be adjusted according to the actual application. The plurality of limiting columns 101 are arranged in an annular equidistant array on the rear side of the pump base 3, and the plurality of limiting sleeves 111 are arranged in an annular equidistant array on the front side of the U-shaped support base 2, so that the limiting columns 101 can be plugged in with the limiting sleeves 111 at will, and the direction of the pipe groove 32 at the lower end of the pump base 3 can be adjusted accordingly.

[0033] Further, a plurality of threaded holes 33 are formed on the outer side of the pump base 3, a plurality of through holes 43 are formed on the outer side of the pump cover 4, the plurality of threaded holes 33 and the plurality of through holes 43 are one-to-one corresponding, the pump base 3 and the pump cover 4 are fixed through the fixing bolts 44, and the fixing bolts 44 pass through the through holes 43 and are screw-connected in the threaded holes 33 at the corresponding positions.

[0034] Specifically, the pump base 3 and the pump cover 4 are fixed by the fixing bolts 44, so that the disassembly and assembly are more convenient. When the pump cover 4 needs to be opened, the fixing bolts 44 are unscrewed and separated from the threaded holes 33, and then the pump cover 4 can be easily taken off from the front side of the pump base 3. When the pump cover 4 needs to be closed, the pump cover 4 is buckled on the front side of the pump base 3, and then the fixing bolts 44 are sequentially inserted into the through holes 43 and the threaded holes 33, so that the disassembly and assembly process of the pump base 3 and the pump cover 4 is greatly simplified, and the maintenance efficiency of the peristaltic pump is improved.

[0035] Further, the roller group 7 comprises a fixed disc 71, a threaded short column 72 and a roller 73, the threaded short column 72 is fixedly connected to the front side center position of the fixed disc 71, the roller 73 is movably sleeved on the outer side of the threaded short column 72 and is fixed through a nut 74, the rear side of the fixed disc 71 is fixedly connected with a guide block 75, and the guide block 75 is slidably connected in the guide groove 61.

[0036] Specifically, when the roller 73 needs to be replaced, the roller 73 can be removed by simply unscrewing the nut 74 from the threaded stub 72, which is simple and convenient.

[0037] Further, the adjusting assembly 8 comprises an adjusting disc 81 rotatably sleeved outside the shaft 5, which is located at the rear side of the rotating disc 6 and inside the pump base 3. The surface of the adjusting disc 81 is provided with three groups of arc-shaped grooves two 811 arranged at an inclination. The rear side of the guide block 75 is fixedly connected with a connecting stub 76 which is slidingly connected inside the corresponding arc-shaped groove two 811. Clockwise rotation of the adjusting disc 81 can realize the synchronous movement of the three groups of guide blocks 75 towards the center of the rotating disc 6. The surface of the rotating disc 6 is provided with an arc-shaped groove one 63 at the upper right side. The front side of the adjusting disc 81 is fixedly connected with a lever 82 which can slide inside the arc-shaped groove one 63. The surface of the adjusting disc 81 is provided with a threaded hole 812 at the upper right side. The inside of the threaded hole 812 is detachably connected with a limiting bolt 83 for limiting the rotation of the adjusting disc 81. The lever 82 and the limiting bolt 83 are respectively located at the two ends inside the arc-shaped groove one 63.

[0038] Specifically, when the rubber hose 9 needs to be disassembled, the limiting bolt 83 is unscrewed from the threaded hole 812, and at this time the adjusting disc 81 is in a rotatable state relative to the rotating disc 6. Then the lever 82 is clockwise pushed to move from one end of the arc-shaped groove one 63 to the other end, thereby driving the adjusting disc 81 to rotate clockwise, and at this time the arc-shaped groove two 811 slides relative to the connecting stub 76. Since the arc-shaped groove two 811 is arranged at an inclination, the connecting stub 76 drives the guide block 75 to move downward in the guide groove 61 in the process, thereby driving the roller 73 to move downward. At this time, the staff can easily take out the rubber hose 9 for replacement. After the replacement of the rubber hose 9 is completed, the lever 82 is counterclockwise pushed to drive the adjusting disc 81 to rotate counterclockwise, thereby indirectly driving the roller 73 to move upward, so that the roller 73 re-exerts pressure on the replaced rubber hose 9. Then the limiting bolt 83 is screwed into the threaded hole 812 to restore the relative fixed state of the adjusting disc 81 and the rotating disc 6.

[0039] Further, the limiting column 101 comprises a base 1011 and a hexagonal inserting rod 1012. The base 1011 is fixedly connected to the rear side of the pump base 3. The hexagonal inserting rod 1012 is fixedly connected to the rear side of the base 1011. The rear side of the hexagonal inserting rod 1012 is fixedly connected with a main magnet 1013. The front side of the limiting sleeve one 111 is provided with a first hexagonal groove three 1111 for inserting the hexagonal inserting rod 1012. The inside of the first hexagonal groove three 1111 is fixedly connected with a secondary magnet one 1112 for magnetic attraction with the main magnet 1013.

[0040] Specifically, when the hexagonal insertion rod 1012 is inserted into the first hexagonal groove three 1111, magnetic attraction occurs between the main magnet 1013 and the auxiliary magnet one 1112, forming a firm suction connection, thereby effectively preventing the hexagonal insertion rod 1012 from slipping out or loosening from the first hexagonal groove three 1111. This design can ensure that the relative position between the pump seat 3 and the U-shaped support seat 2 is always fixed, avoiding the relative displacement or instability of the two during use. When it is necessary to disassemble the pump seat 3 and the U-shaped support seat 2, an external force is applied to pull the pump seat 3 away from the U-shaped support seat 2, and the pump seat 3 can drive the hexagonal insertion rod 1012 to disengage from the first hexagonal groove three 1111. Under the action of the external force, the main magnet 1013 and the auxiliary magnet one 1112 are separated from the suction state, thereby smoothly completing the disassembly operation. This disassembly method is simple and convenient, and does not require complex tools, greatly improving the efficiency of maintenance and disassembly.

[0041] Further, the pump seat 3, the pump cover 4 and the shaft rod 5 are provided with multiple groups, the adjacent two groups of shaft rods 5 are inserted into each other, the front side of the shaft rod 5 is provided with a hexagonal groove two 52 matched with the hexagonal head 51, the hexagonal head 51 of the shaft rod 5 located at the front side is movably inserted into the hexagonal groove two 52 of the shaft rod 5 located at the rear side, the front side of the pump cover 4 is connected with an auxiliary connecting limiting piece two 12 matched with the main connecting limiting piece 10, and the auxiliary connecting limiting piece two 12 of the pump cover 4 located at the rear side and the main connecting limiting piece 10 of the pump seat 3 located at the front side are matched with each other to form a detachable fixed connection.

[0042] Specifically, the multiple groups of shaft rods 5 are connected in series, so that under the driving of one group of motors 1, the multiple groups of shaft rods 5 can be driven to rotate together, and the installation of the multiple groups of pump seats 3 can be realized, thereby greatly improving the working efficiency of the peristaltic pump.

[0043] Further, the auxiliary connecting limiting piece two 12 comprises multiple groups of limiting sleeves two 121, the multiple groups of limiting sleeves two 121 are arranged in an annular equidistant array on the front side of the pump cover 4, the front side of the limiting sleeve two 121 is provided with a second hexagonal groove three 1211 for inserting the hexagonal insertion rod 1012, and the second hexagonal groove three 1211 is fixedly connected with an auxiliary magnet two 1212 for magnetic attraction with the main magnet 1013.

[0044] Specifically, when the multiple groups of pump seats 3 need to be installed, the hexagonal insertion rod 1012 of the pump seat 3 located at the front side is inserted into the second hexagonal groove three 1211 of the pump cover 4 located at the rear side, and the relative position of the two can be fixed under the magnetic attraction of the main magnet 1013 and the auxiliary magnet two 1212.
