Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, and more specifically, to a peristaltic pump with a self-locking pump cover that allows for easy pipe replacement. Background Technology

[0002] In peristaltic pump applications, the conventional internal tube is fitted to the base. As the wheel assembly rotates, the rollers repeatedly press against the internal tube, causing it to continuously open and close, generating negative pressure to achieve fluid transfer. The internal tube of a peristaltic pump is a wear part and needs periodic replacement. Therefore, replacement requires disassembly and reassembly of various parts. In existing technologies, some peristaltic pumps use a bolt-fixed pump cover structure, requiring tools for disassembly when replacing the pump tube, resulting in cumbersome and inefficient operations. Therefore, we have made an improvement by proposing a self-locking pump cover type peristaltic pump with a convenient tube replacement mechanism. The quick disassembly and reassembly of the pump cover makes tube replacement much more convenient. Utility Model Content

[0003] The main purpose of this invention is to provide a self-locking peristaltic pump with a convenient tube replacement mechanism, which can effectively solve the problem of low disassembly and assembly efficiency in the tube replacement process of existing peristaltic pumps.

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

[0005] A self-locking peristaltic pump with a convenient pipe replacement pump cover includes a base. An upper support is installed on one side of the base via connecting bolts. A wheel assembly is rotatably installed between the upper support and the base via a first bearing and a second bearing. A pump cover body is installed on the outer side of the upper support and the base. A pipe cavity is formed between the pump cover body and the wheel assembly. A motor is installed at the lower end of the base. A splined shaft is fixedly installed at the output end of the motor. The splined shaft is connected to the wheel assembly.

[0006] Preferably, the upper support has an upper buckle groove on one side, and the base has a lower buckle groove on one side.

[0007] Preferably, the upper and lower snap-fit ​​grooves are located on both sides of the pump cover body.

[0008] Preferably, an upper latching block and a lower latching block are respectively provided on both sides of the pump cover body. The upper latching block is engaged with the upper latching groove, and the lower latching block is engaged with the lower latching groove.

[0009] Preferably, the height of the upper latching block is located above the lower latching block.

[0010] Preferably, the upper support surface located on one side of the upper buckle groove is provided with a guide slope.

[0011] Preferably, the upper support has an upper positioning boss on its upper surface, and the base has a lower positioning boss on one side of its upper surface.

[0012] Preferably, an upper positioning groove and a lower positioning groove are respectively provided on both sides of the lower surface of the pump cover body. The upper positioning groove is limited to the upper positioning boss, and the lower positioning groove is limited to the lower positioning boss.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) In this application, to remove the pump cover body after it has been closed, the upper latch block must be disengaged before it can be removed. However, since the peristaltic pump principle requires squeezing the hose, the pump cover body will be subjected to an outward force regardless of where the rollers in the wheel assembly are pressed against it, preventing the upper latch block from disengaging. This achieves self-locking of the pump cover body and automatic locking of the upper latch block after the pump cover body is assembled. When removing it, simply push the pump cover body to one side to disengage the upper latch block and flip it over for removal. Compared to the disassembly and assembly of the pump cover in existing peristaltic pumps, this application can achieve quick opening and closing of the pump cover, making subsequent tube replacement more convenient.

[0020] 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.

[0021] like Figures 1 to 4 As shown, a self-locking peristaltic pump with a convenient pipe replacement pump cover includes a base 6. An upper support 2 is installed on one side of the base 6 via connecting bolts 9. A wheel set 4 is rotatably installed between the upper support 2 and the base 6 via a first bearing 3 and a second bearing 5. A pump cover body 1 is installed on the outer side of the upper support 2 and the base 6. A pipe cavity 10 is formed between the pump cover body 1 and the wheel set 4. A motor 8 is installed at the lower end of the base 6. A splined shaft 7 is fixedly installed at the output end of the motor 8. The splined shaft 7 is connected to the wheel set 4.

[0022] The assembly sequence of the peristaltic pump in this application is as follows:

[0023] 1. Assemble the base 6 and the motor 8 and tighten them with Phillips head screws;

[0024] 2. Assemble the wheel frame, axle, rollers, and bearings into wheel set 4;

[0025] 3. Align the splined shaft 7 and install it on the output end of the motor 8;

[0026] 4. Mount wheel assembly 4 onto base 6 along the notch of spline shaft 7;

[0027] 5. Align the upper support 2 with the first bearing 3 and install it on the wheel set 4. Then use two connecting bolts 9 to lock the wheel set 4 on the base 6 to fix it.

[0028] 6. Assemble the connector or pipe clamp with the internal pipe. Assemble the internal pipe and position it within the pipe cavity 10;

[0029] 7. Install the combined built-in tube winding wheel assembly 4 on the pump head;

[0030] 8. Install the pump cover body 1 onto the base 6.

[0031] In this embodiment, an upper buckle groove 201 is provided on one side of the upper support 2, and a lower buckle groove 602 is provided on one side of the base 6.

[0032] The upper snap-fit ​​groove 201 and the lower snap-fit ​​groove 602 are located on both sides of the pump cover body 1, respectively.

[0033] In this embodiment, an upper latching block 102 and a lower latching block 101 are respectively provided on both sides of the pump cover body 1. The upper latching block 102 is engaged with the upper latching groove 201, and the lower latching block 101 is engaged with the lower latching groove 602.

[0034] The upper latching block 102 and the lower latching block 101 can be latched with the upper latching groove 201 and the lower latching groove 602 respectively. When there is an internal pipe inside the pipe cavity 10, the pump cover body 1 can be fixed on the outside of the upper support 2 and the base 6 under the support of the internal pipe. The upper latching groove 201 allows the upper latching block 102 to automatically lock after the pump cover body 1 is pressed into place. The lower latching groove 602 is a movable latching position, which allows the lower latching block 101 to be inserted into the lower latching groove 602 in advance when closing the cover, and then the upper latching block 102 to be latched with the upper latching groove 201.

[0035] The upper latching block 102 is located above the lower latching block 101.

[0036] In this embodiment, a guide slope 202 is provided on the surface of the upper support 2 located on one side of the upper buckle groove 201.

[0037] The guide ramp 202 allows the snap-on block 102 on the ramp to quickly move downwards along the ramp, making it easier for the upper snap-on block 102 to snap into the upper snap-on groove 201, which is beneficial for closing the pump cover body 1.

[0038] In this embodiment, the upper support 2 has an upper positioning boss 203 on its upper surface, and the base 6 has a lower positioning boss 601 on one side of its upper surface.

[0039] The pump cover body 1 has an upper positioning groove 104 and a lower positioning groove 103 on both sides of its lower surface. The upper positioning groove 104 is matched with the upper positioning boss 203, and the lower positioning groove 103 is matched with the lower positioning boss 601.

[0040] The upper positioning groove 104 and the lower positioning groove 103 can respectively cooperate with the upper positioning boss 203 and the lower positioning boss 601 to limit the positioning, so that the pump cover body 1 can be accurately aligned with the upper support 2 and the base 6 during the closing process, which makes it convenient for users to quickly close the cover and makes the pipe replacement process more convenient.

[0041] It should be noted that to remove the closed pump cover body 1, the upper latching block 102 must be disengaged first. However, since the peristaltic pump principle requires squeezing the tubing, regardless of where the rollers in the wheel assembly 4 are pressed against the pump cover body 1, the pump cover body 1 will be subjected to an outward force, preventing the upper latching block 102 from disengaging. This achieves self-locking of the pump cover body 1 and automatic locking of the upper latching block 102 after the pump cover body 1 is assembled. For removal, simply push the pump cover body 1 to one side to disengage the upper latching block 102, then flip it over for removal. Compared to the existing peristaltic pump cover disassembly and assembly, this application allows for quick opening and closing of the pump cover, making subsequent tubing replacement more convenient.

[0042] Installation steps for the pump cover of this convenient, self-locking peristaltic pump with a replaceable pump cover:

[0043] 1. First, insert the lower latching block 101 on one side of the pump cover body 1 into the lower latching groove 602;

[0044] 2. Then press the pump cover body 1. During the pressing process, the upper buckle block 102 can be guided into the upper buckle groove 201 through the guide slope 202 and locked in place.

[0045] 3. During the clamping process, the upper positioning groove 104 and the lower positioning groove 103 cooperate with the upper positioning boss 203 and the lower positioning boss 601 respectively to achieve precise closing of the cover;

[0046] 4. After the cover is closed, the pump cover body 1 will be subjected to an outward force through the hose installed inside the pipe cavity 10, so that the upper latch block 102 cannot be disengaged from the upper latch slot 201, thereby realizing the self-locking operation of the pump cover body 1.

[0047] 5. When opening the cover, simply push the pump cover body 1 to one side to disengage the upper latching block 102 from the upper latching groove 201 and flip it over to remove it.

[0048] 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.
