Description

Technical Field

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

[0002] The operating principle of a peristaltic pump is based on peristaltic motion. When the pump's driver is activated, it drives the squeeze rollers on the pump head along the length of the hose. As the squeeze rollers move, they apply pressure to the hose, sealing it and pushing the fluid forward. When the squeeze rollers move away, the hose returns to its original shape, creating negative pressure and drawing in new fluid. This peristaltic motion enables peristaltic pumps to achieve precise flow control and pulsation-free fluid delivery.

[0003] After a long period of use, the hose and some parts inside the existing peristaltic pump will inevitably be damaged. However, it is inconvenient to disassemble and inspect the existing peristaltic pump, which affects the practicality of the peristaltic pump. Utility Model Content

[0006] The effect achieved by the above components is: when the peristaltic pump needs to be repaired, the staff first pulls the plug rod, and the plug rod is removed from the socket of the L-shaped plate. At this time, the staff moves the cover plate, and the cover plate is removed from one side of the pump head. The staff repairs the parts in the pump head. When the repair is completed, the staff moves the cover plate again, and the L-shaped plate on the cover plate is inserted into the square tube. At this time, the sealing ring on one side of the cover plate fits with the pump head, thereby sealing the gap between the cover plate and the pump head. After that, the staff inserts the plug rod through the square tube into the socket of the L-shaped plate, thereby fixing the cover plate. When the peristaltic pump needs to be used, the staff turns on the motor, and the motor drives the peristaltic roller in the pump head to rotate. The peristaltic roller squeezes the hose, and the closed hose promotes the flow of the liquid inside, thereby realizing the normal operation of the peristaltic pump. The fixing device facilitates the staff to install and disassemble the cover plate, which makes it convenient for the staff to repair the parts inside the peristaltic pump when the peristaltic pump is damaged.

[0007] Preferably, a groove is provided on one side of the cover plate, and the cover plate is fixedly connected to the pull plate via the groove.

[0008] The effect achieved by the above components is: the contact area between the staff's hands and the cover is increased by the pull plate in the groove, making it easier for the staff to move the cover.

[0010] The effect achieved by the above components is: by inserting the positioning rod of the cover plate into the positioning hole of the pump head, the cover plate is limited, thereby avoiding shaking between the cover plate and the pump head.

[0011] Preferably, one end of the insertion rod is fixedly connected to a pull rope, and one end of the pull rope is fixedly connected to the square tube.

[0012] The effect achieved by the above components is: by setting the pull rope, the maximum displacement of the insertion rod is limited, thereby preventing the insertion rod from falling when not in use.

[0013] Preferably, auxiliary devices are provided on both sides of the pump head corresponding to the hose, and the auxiliary devices include two symmetrical U-shaped plates, and the two U-shaped plates are fixedly connected to the two sides of the pump head respectively.

Both arms of the U-shaped plate are threadedly connected to a screw, and one end of the screw is rotatably connected to a splint, and the cross-section of the splint is arc-shaped.

[0014] The effect achieved by the above components is: after connecting the two ends of the pipe and the hose, the staff rotates the screw on the U-shaped plate, and the screw brings the two clamps closer to each other. Finally, the clamps squeeze the pipe, thereby achieving the effect of fixing the pipe. The auxiliary device achieves the effect of fixing the pipe connected to the hose, thereby preventing the pipe and the hose from detaching.

[0015] Preferably, one end of the screw is fixedly connected to a handle, and the surface of the handle is fixedly connected to two symmetrical protrusions.

[0016] The effect achieved by the above components is that the handle is provided to facilitate the staff to rotate the screw, thereby bringing convenience to the staff.

[0018] The effect achieved by the above components is: by setting the limit rod, the effect of limiting the moving direction of the splint is achieved, thereby preventing the splint from rotating and improving the stability of the splint movement.

[0019] Preferably, a rubber pad is fixedly connected to a side of the splint away from the screw rod, and the size of the rubber pad is adapted to the size of the splint.

[0020] The effect achieved by the above components is: by arranging the rubber pad, the pipeline is protected and the pipe is prevented from being damaged by the clamping plate.

[0021] In summary, the beneficial effects of the present invention are as follows:

[0022] When the peristaltic pump needs to be repaired, the staff first pulls the rod, and the rod is removed from the socket of the L-shaped plate. At this time, the staff moves the cover plate, and the cover plate is removed from the side of the pump head. The staff repairs the parts in the pump head. When the repair is completed, the staff moves the cover plate again, and the L-shaped plate on the cover plate is inserted into the square tube. At this time, the sealing ring on one side of the cover plate fits with the pump head, thereby sealing the gap between the cover plate and the pump head. After that, the staff inserts the rod through the square tube into the socket of the L-shaped plate, thereby fixing the cover plate. When the peristaltic pump needs to be used, the staff turns on the motor, and the motor drives the peristaltic roller in the pump head to rotate. The peristaltic roller squeezes the hose, and the closed hose promotes the flow of the liquid inside, thereby realizing the normal operation of the peristaltic pump.

The size of the insertion rod 54 is adapted to the size of the hole 55. A sealing ring 56 is fixedly connected to one side of the cover plate 53. When the peristaltic pump needs to be repaired, the staff first pulls the plug rod 54, and the plug rod 54 is removed from the socket 55 of the L-shaped plate 52. At this time, the staff moves the cover plate 53, and the cover plate 53 is removed from one side of the pump head 2. The staff repairs the parts in the pump head 2. When the repair is completed, the staff moves the cover plate 53 again, and the L-shaped plate 52 on the cover plate 53 is inserted into the square tube 51.

[0033] Working principle: When the peristaltic pump needs to be repaired, the staff first pulls the plug rod 54, and the plug rod 54 is removed from the socket 55 of the L-shaped plate 52. At this time, the staff moves the cover plate 53 through the pull plate 510 in the groove 59, and the cover plate 53 is removed from the side of the pump head 2. The staff repairs the parts in the pump head 2. When the repair is completed, the staff moves the cover plate 53 again, and the positioning rod 57 of the cover plate 53 is inserted into the positioning hole 58 of the pump head 2, achieving the effect of limiting the cover plate 53. The L-shaped plate 52 on the cover plate 53 is inserted into the square tube 51. At this time, the sealing ring 56 on one side of the cover plate 53 fits with the pump head 2, achieving the effect of fixing the cover plate. The gap between the plate 53 and the pump head 2 is sealed, and then the staff inserts the rod 54 through the square tube 51 into the socket 55 of the L-shaped plate 52, thereby fixing the cover plate 53. When the peristaltic pump needs to be used, the staff turns on the motor 1, and the motor 1 drives the peristaltic roller 3 in the pump head 2 to rotate. The peristaltic roller 3 squeezes the hose 4, and the closed hose 4 promotes the flow of the internal liquid, thereby realizing the normal operation of the peristaltic pump. The fixing device 5 is used to facilitate the staff to install and disassemble the cover plate 53, which makes it convenient for the staff to repair the internal parts of the peristaltic pump when the peristaltic pump is damaged.

[0034] After connecting the two ends of the pipe to the hose 4, the staff rotates the screw 63 on the U-shaped plate 61 through the handle 65. The screw 63 brings the two clamps 64 closer to each other. Finally, the clamps 64 squeeze the pipe with the help of rubber pads 67, thereby achieving the effect of fixing the pipe. The auxiliary device 6 achieves the effect of fixing the pipe connected to the hose 4, preventing the pipe from being separated from the hose 4.
