Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, specifically a peristaltic pump wheel assembly. Background Technology

[0002] A peristaltic pump, also known as a hose pump, is a fluid transport device that works based on the principle of peristaltic motion or squeezing. Its core consists of three main parts: a driver, a pump head, and a hose. During the pumping process, the driver drives the pump head to rotate, and the rollers in the pump head alternately squeeze the hose, causing the fluid to move forward inside the hose. This unique pumping method ensures that the fluid only comes into contact with the inner wall of the hose, minimizing the possibility of contamination.

[0003] Regarding the aforementioned technologies, when using a peristaltic pump, a flexible tube is installed inside the pump and contacts the rollers of the pump head. The rollers of the pump head squeeze the tube when they rotate, thereby completing the fluid delivery. However, a protective shell is usually installed at the front of the peristaltic pump with screws. When installing or removing the tube, special tools are needed to remove the screws on the protective shell and remove the protective shell before the tube can be installed or removed. The overall process of installing and removing the tube is quite inconvenient.

[0004] To address these issues, this invention provides a peristaltic pump wheel assembly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a peristaltic pump wheel assembly that solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a peristaltic pump wheel assembly, including a peristaltic pump body, a protective cover installed on the front wall of the peristaltic pump body, a drive shaft inside the peristaltic pump body passing through the protective cover and fixedly installed with a roller pressing assembly through a bearing, a protective assembly installed on the front wall of the protective cover, a hose detachably installed on the inner wall of the roller pressing assembly, a limit assembly installed on the outer wall of the hose, and a control panel installed on the front wall of the peristaltic pump body;

[0007] The roller pressing assembly includes a rotating seat. The rear wall of the rotating seat is fixedly connected to the front end of the drive shaft inside the peristaltic pump body. A ring is fixedly installed on the inner wall of the protective cover. The top and bottom walls of the rotating seat are provided with mounting grooves. Rotating rollers are rotatably installed on the inner walls of the two mounting grooves. The outer walls of the two rotating rollers are rolledly connected to the outer wall of the hose. The rotating seat is located in the inner wall of the ring, and the inner wall of the ring is in contact with the outer wall of the hose.

[0008] The protective assembly includes a protective plate. The left side wall of the protective plate is hinged to the front wall of the protective cover. Connecting seats are fixedly installed at the top and bottom of the outer side wall of the protective plate. Elastic elements are fixedly installed on the outer side walls of the two connecting seats. V-shaped locking blocks are fixedly installed on the side walls of the two elastic elements. V-shaped grooves are formed on the inner walls of the two V-shaped locking blocks. V-shaped limiting seats are fixedly installed on the right side wall of the protective cover at the positions corresponding to the V-shaped locking blocks. Grooves are formed on the rear walls of the V-shaped limiting seats. The rear wall of the protective plate fits against the front wall of the protective cover. A transparent observation window is installed on the front wall of the protective plate. The inner walls of the two V-shaped grooves fit against the outer walls of the corresponding V-shaped limiting seats. The outer walls of the V-shaped locking blocks fit against the inner walls of the corresponding grooves.

[0009] The above technical solution makes it easier to install and remove the hose, and the operation is simple for workers, eliminating the need to use special tools to remove screws to complete the installation and fixation.

[0010] Furthermore, the rotating seat is located in the inner wall of the ring, and the inner wall of the ring is in contact with the outer wall of the hose.

[0012] Furthermore, the rear wall of the protective plate is fitted to the front wall of the protective cover, the front wall of the protective plate is equipped with a transparent observation window, the inner walls of the two V-shaped grooves are fitted to the outer walls of the corresponding V-shaped limit seats, and the outer wall of the V-shaped card block is fitted to the inner wall of the corresponding groove.

[0013] With the above technical solution, the protective plate abuts against the front wall of the protective cover, and the working status of the peristaltic pump and whether the hose is delivering fluid normally can be seen in real time through the transparent observation window.

[0014] Furthermore, the limiting component includes two cross-shaped retainers, the inner walls of which are fitted and fixed to the bottom of the outer wall of the hose. The bottom of the ring has through grooves on both the left and right sides, and the outer walls of the hose are fitted to the inner walls of the corresponding through grooves on both the left and right sides.

[0015] The above technical solution enables the flexible tube to move the cross-shaped retainer, allowing the cross-shaped retainer to enter the inner wall of the corresponding cross-shaped retainer groove to complete the installation and fixation of the flexible tube.

[0016] Furthermore, cross-shaped slots are provided on both the left and right sides of the bottom of the front wall of the protective cover, and the inner walls of the two cross-shaped slots are fitted to the outer walls of the corresponding cross-shaped slots.

[0017] Through the above technical solution, the cross-shaped groove and the cross-shaped bracket work together to achieve the installation limit of the hose.

[0018] Furthermore, the front walls of both cross-shaped card holders are fitted to the rear wall of the protective plate.

[0019] Through the above technical solution, the protective plate abuts and fixes against the cross-shaped bracket after it is closed.

[0020] Furthermore, a handle is fixedly installed on the top wall of the peristaltic pump body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please see Figures 1-4 A peristaltic pump wheel assembly includes a peristaltic pump body 1, a protective cover 4 installed on the front wall of the peristaltic pump body 1, a drive shaft inside the peristaltic pump body 1 passing through the protective cover 4 and a roller pressing assembly 6 fixedly installed thereon via a bearing, a protective assembly 5 installed on the front wall of the protective cover 4, a hose 7 detachably installed on the inner wall of the roller pressing assembly 6, a limit assembly 8 installed on the outer wall of the hose 7, and a control panel 3 installed on the front wall of the peristaltic pump body 1.

[0033] The roller pressing assembly 6 includes a rotating seat 62. The rear wall of the rotating seat 62 is fixedly connected to the front end of the drive shaft inside the peristaltic pump body 1. A ring 61 is fixedly installed on the inner wall of the protective cover 4. The top and bottom walls of the rotating seat 62 are provided with mounting grooves 64. Rotating rollers 63 are rotatably installed on the inner walls of the two mounting grooves 64. The outer walls of the two rotating rollers 63 are rolledly connected to the outer wall of the hose 7.

[0034] The protective component 5 includes a protective plate 53. The left side wall of the protective plate 53 is hinged to the front wall of the protective cover 4. Connecting seats 55 are fixedly installed at the top and bottom of the outer side wall of the protective plate 53. Elastic elements 56 are fixedly installed on the outer side walls of the two connecting seats 55. V-shaped locking blocks 57 are fixedly installed on the side walls of the two elastic elements 56. V-shaped grooves 58 are opened on the inner walls of the two V-shaped locking blocks 57. V-shaped limiting seats 51 are fixedly installed on the right side wall of the protective cover 4 at the positions corresponding to the V-shaped locking blocks 57. Grooves 52 are opened on the rear walls of the V-shaped limiting seats 51. The rear wall of the protective plate 53 is attached to the front wall of the protective cover 4. A transparent observation window 54 is installed on the front wall of the protective plate 53. The inner walls of the two V-shaped grooves 58 are attached to the outer walls of the corresponding V-shaped limiting seats 51. The outer walls of the V-shaped locking blocks 57 are attached to the inner walls of the corresponding grooves 52.

[0035] In this embodiment of the present invention, the purpose of this arrangement is that when the drive shaft inside the peristaltic pump body 1 rotates, it will drive the rotating seat 62 and the rotating roller 63 to rotate in the inner wall of the ring 61. The rotating roller 63 squeezes the hose 7, thereby completing the delivery of fluid inside the hose 7. The fluid moves forward in the hose 7. This unique pumping method ensures that the fluid only contacts the inner wall of the hose 7, minimizing the possibility of contamination.

[0036] The protective component 5 is designed to seal and limit the protective cover 4 after the protective plate 53 is closed. It also drives the V-shaped locking block 57 and V-shaped groove 58 to engage and install on the outer wall of the V-shaped limiting seat 51 through the elastic element 56, thereby completing the closing and limiting of the protective plate 53. It eliminates the need to use screwdrivers or other tools to remove screws, making it more convenient and simple to install and remove the hose 7.

[0037] Example 2:

[0038] Please see Figures 1-4This embodiment provides a technical solution based on embodiment one: the limiting component 8 includes two cross-shaped retaining seats 83, the inner walls of the two cross-shaped retaining seats 83 are sleeved and fixed to the bottom of the outer wall of the hose 7, the bottom left and right sides of the ring 61 are provided with through grooves 81, the left and right sides of the outer wall of the hose 7 are fitted with the inner walls of the corresponding through grooves 81, the bottom left and right sides of the front wall of the protective cover 4 are provided with cross-shaped retaining slots 82, the inner walls of the two cross-shaped retaining slots 82 are fitted with the outer walls of the corresponding cross-shaped retaining seats 83, the front walls of the two cross-shaped retaining seats 83 are fitted with the rear wall of the protective plate 53, and a handle 2 is fixedly installed on the top wall of the peristaltic pump body 1;

[0039] In this embodiment of the utility model, the purpose of this setting is that the setting of the limiting component 8 prevents the hose 7 from moving when it is installed during operation. The cross-shaped retainer 83 and the cross-shaped groove 82 can limit the inlet and outlet of the hose 7 to prevent positional deviation. The handle 2 can freely drive the peristaltic pump body 1 to move for easy carrying.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0041] When installing the hose 7 during operation, first move one end of the hose 7 to drive the corresponding cross-shaped retainer 83 into the inner wall of the cross-shaped retainer groove 82 to complete the limiting. Then, insert the outer wall of the hose 7 through the through groove 81 into the inside of the ring 61, so that it fits against the outer wall of the rotating roller 63 installed on the rotating seat 62. Then, after the other end of the hose 7 passes through the corresponding through groove 81, it drives the cross-shaped retainer 83 into the inner wall of another empty cross-shaped retainer groove 82. Next, rotate the protective plate 53 to move the connecting seat 55, the elastic element 56, and the V-shaped retaining block 57. When the elastic element 56 drives the V-shaped retaining block 57 to gradually contact the V-shaped limiting seat 51, the elastic element 56 will expand outward after being stressed, so that the V-shaped retaining block 57 and the V-shaped retaining seat 51 can move together. The V-groove 58 can be snapped onto the outer wall of the V-shaped limit seat 51. At the same time, the outer wall of the V-shaped locking block 57 fits against the inner wall of the groove 52. Then, the protective plate 53 fits against the front wall of the protective cover 4 and the cross-shaped locking seat 83 to complete the abutment and fixation. Finally, the installation of the outer wall of the hose 7 is completed. When the hose 7 needs to be removed, the V-shaped locking block 57 is pulled outward to make the V-groove 58 disengage from the outer wall of the V-shaped limit seat 51. The V-shaped locking block 57 drives the elastic element 56 to expand and deform outward. By rotating the protective plate 53, it disengages from the protective cover 4 and the cross-shaped locking seat 83. The hose 7 is moved to drive the cross-shaped locking seat 83 to disengage from the cross-shaped locking groove 82. The hose 7 disengages from the contact between the ring 61 and the rotating roller 63, and finally the hose 7 is removed.
