Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, and more specifically, to an easy-to-install peristaltic pump with convenient tube replacement. Background Technology

[0002] In peristaltic pump applications, the conventional internal tubing is fitted to the base. As the wheel assembly rotates, the rollers repeatedly squeeze the internal tubing, causing it to continuously open and close, generating negative pressure to achieve fluid transfer. The internal tubing used to deliver the liquid in a peristaltic pump is the only consumable. Due to its frequent use, its lifespan is short, requiring frequent replacement. The current process for replacing the tubing in peristaltic pumps is cumbersome, significantly reducing maintenance efficiency. Utility Model Content

[0003] The main purpose of this utility model is to provide an easy-to-install peristaltic pump with convenient tubing replacement, which can effectively solve the problem that the process of replacing the tubing of the peristaltic pump in the background art is relatively cumbersome, resulting in a significant reduction in the efficiency of maintenance work.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An easy-to-install peristaltic pump with convenient tube replacement includes a base, a motor is provided on the lower surface of the base, and a combined internal tube is provided on the upper surface of the base;

[0006] The motor output shaft passes through the base and is fitted with a wheel frame. Several rollers are rotatably installed between the two sides of the inner wall of the wheel frame. An upper support is provided on the upper surface of the base.

[0007] The pump cover is detachably and fixedly installed on the upper surface of the base via a locking slider.

[0008] Preferably, each roller is rotatably mounted between the two sides of the inner wall of the wheel frame via a small shaft.

[0009] Preferably, the upper surface of the base is integrally provided with a pipe clamp structure, and the combined internal pipe engages with the pipe clamp structure.

[0010] Preferably, the wheel frame is rotatably connected to the upper support via bearings.

[0011] Preferably, the upper support is detachably fixed to the base by screws.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) By pushing the locking slider backward, the locking slider's snap-fit ​​part moves to the limiting part of the limiting groove on the pump cover surface. At this time, the lower end of the locking slider moves to the opening of the base. Then, the worker controls the locking slider to swing, causing it to move the pump cover, so that the worker can quickly disassemble the pump cover. After disassembling the upper support, the worker removes the combined internal tube. After replacing the new combined internal tube, the worker installs the upper support and the pump cover on the base, and then pushes the locking slider forward to fix the position of the pump cover, thus completing the quick replacement of the combined internal tube, which greatly improves the efficiency of maintenance work.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1-4 As shown, an easy-to-install peristaltic pump with convenient tube replacement includes a base 10, a motor 11 is provided on the lower surface of the base 10, and a combined internal tube 9 is provided on the upper surface of the base 10.

[0021] The output shaft of motor 11 passes through base 10 and is fitted with wheel frame 6. Several rollers 8 are rotatably installed between the two sides of the inner wall of wheel frame 6. An upper support 4 is provided on the upper surface of base 10.

[0022] The pump cover 2 is detachably and fixedly installed on the upper surface of the base 10 via the locking slider 1.

[0023] The operator starts the motor 11, causing its output shaft to drive the wheel frame 6 to rotate. This causes the roller 8 to rotate with the wheel frame 6, allowing the roller 8 to compress the combined internal tube 9, enabling the combined internal tube 9 to transport liquid. When the combined internal tube 9 needs to be replaced, the operator pushes the locking slider 1 backward, causing the locking part of the locking slider 1 to move to the limiting part of the limiting groove on the surface of the pump cover 2. At this time, the lower end of the locking slider 1 moves to the opening of the base 10. Then, the operator controls the locking slider 1 to swing, causing it to move the pump cover 2, thus enabling the operator to quickly disassemble the pump cover 2. After disassembling the upper support 4, the operator removes the combined internal tube 9. After replacing the combined internal tube 9, the operator installs the upper support 4 and the pump cover 2 on the base 10, and then pushes the locking slider 1 forward to fix the position of the pump cover 2, thus completing the quick replacement of the combined internal tube 9, greatly improving the efficiency of the maintenance work.

[0024] In another embodiment of this utility model, each roller 8 is rotatably mounted between the two sides of the inner wall of the wheel frame 6 via a small shaft 7.

[0025] By setting the small shaft 7, the roller 8 can rotate stably, thereby enabling the roller 8 to stably squeeze the combined internal tube 9, and thus enabling the liquid to be transported stably.

[0026] In another embodiment of this utility model, a pipe clamp structure is integrally provided on the upper surface of the base 10, and the combined built-in pipe 9 is engaged with the pipe clamp structure.

[0027] By setting up a pipe clamp structure, the combined internal pipe 9 can be stably connected to the base 10, preventing the combined internal pipe 9 from shifting when transporting liquid.

[0028] In another embodiment of this utility model, the wheel frame 6 is rotatably connected to the upper support 4 via the bearing 5.

[0029] The wheel frame 6 is rotatably connected to the upper support 4 via the bearing 5, so that the wheel frame 6 can stably drive the roller 8 to rotate.

[0030] In another embodiment of this utility model, the upper support 4 is detachably and fixedly connected to the base 10 by screws 3.

[0031] By setting screw 3, workers can quickly assemble and disassemble the upper support 4.

[0032] The working principle of this easy-to-install peristaltic pump with convenient tubing replacement:

[0033] In use, the operator starts the motor 11, causing its output shaft to drive the wheel frame 6 to rotate. This causes the roller 8 to rotate with the wheel frame 6, allowing the roller 8 to compress the combined internal tube 9, enabling the combined internal tube 9 to transport liquid. When the combined internal tube 9 needs to be replaced, the operator pushes the locking slider 1 backward, causing the locking part of the locking slider 1 to move to the limiting part of the limiting groove on the surface of the pump cover 2. At this time, the lower end of the locking slider 1 moves to the opening of the base 10. Then, the operator controls the locking slider 1 to swing, causing it to move the pump cover 2, thus enabling the operator to quickly disassemble the pump cover 2. After disassembling the upper support 4, the operator removes the combined internal tube 9. After replacing the combined internal tube 9, the operator installs the upper support 4 and the pump cover 2 on the base 10, and then pushes the locking slider 1 forward to fix the position of the pump cover 2, thus completing the quick replacement of the combined internal tube 9, greatly improving the efficiency of maintenance work.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
