Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump auxiliary equipment, and in particular to an auxiliary device for a fixed dripping peristaltic pump tube. Background Technology

[0002] A peristaltic pump is a device that delivers fluid by squeezing an elastic pump tube. It is widely used in dripping operations in medical, chemical, and laboratory testing fields. In actual use, the peristaltic pump tube is usually placed directly between the rollers and the pressure block of the pump body, and positioning is achieved solely by the squeezing force of the rollers.

[0003] Because the rollers periodically squeeze and release the pump tube when the peristaltic pump is working, the pump tube vibrates. At the same time, the pulling force at both ends of the pump tube during the dripping process can also cause the pump tube to shift, resulting in problems such as decreased dripping accuracy and leakage due to poor sealing at the pump tube and joint.

[0004] To address the above problems, this utility model provides an auxiliary device for fixing the dripping peristaltic pump tube. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary device for fixing a dripping peristaltic pump tube, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a pump body, and a traction mechanism is fixedly connected inside the pump body. The traction mechanism includes a guide groove, an adjusting push rod, a movable seat, a guide slider, a connecting frame, a suspension groove, and a guide spring. The guide groove is opened at the front end of the pump body. The adjusting push rod is fixedly installed in the guide groove. The movable seat is slidably installed in the guide groove. The guide slider is fixedly installed on the outer wall of the movable seat. One side of the movable seat abuts against the output end of the adjusting push rod.

[0007] As a further technical solution of this utility model, the connecting frame is fixedly disposed at the front end of the movable seat, the suspension groove is opened at the front end of the connecting frame, and the adjusting push rod is used to limit the rebound position of the movable seat.

[0008] As a further technical solution of this utility model, a drive mechanism is installed on the rear side of the pump body. The drive mechanism includes a servo motor, a turntable and a mounting bracket. The servo motor is fixedly installed on the rear side of the pump body, and the turntable is fixedly installed on the outer wall of the front output shaft of the servo motor.

[0009] As a further technical solution of this utility model, the mounting frame is fixedly set on the outer wall of the turntable, and the driving mechanism also includes a squeezing roller and a peristaltic tube. The squeezing roller is rotatably set in the mounting frame, and the peristaltic tube is embedded in the front groove of the pump body.

[0010] As a further technical solution of this utility model, the servo motor, turntable, mounting frame and extrusion roller together form an extrusion structure for the peristaltic tube.

[0011] As a further technical solution of this utility model, the pump body is provided with an auxiliary mechanism, which includes an outlet hole and a mounting hole. The outlet hole is opened in the pump body, and the mounting hole is opened at the left end of the pump body.

[0012] As a further technical solution of this utility model, the auxiliary mechanism includes a mounting plate, a fixing bolt and a protective sleeve. The mounting plate is placed close to the left end of the pump body, and the mounting plate also has mounting holes inside.

[0013] As a further technical solution of this utility model, the fixing bolt is installed on the mounting plate and the pump body, the protective sleeve is fixedly set in the mounting plate at the end away from the pump body, and the peristaltic tube is inserted into the protective sleeve.

[0014] This invention provides an auxiliary device for fixing a dripping peristaltic pump tube, which has the following advantages compared with the prior art:

[0015] 1. This design provides an auxiliary device for fixing the dripping peristaltic pump tube. By setting up a traction mechanism (including a guide groove, adjusting push rod, moving seat, guide slider, connecting frame, and suspension groove), and adjusting the abutting relationship between the push rod and the moving seat, and the sliding guiding relationship between the guide slider and the guide groove, the moving seat can slide stably along the guide groove under the pushing of the adjusting push rod and the limiting position of the guide slider. This drives the connecting frame and the suspension groove to be positioned synchronously, thereby achieving the effect of precise positioning of the peristaltic tube through the suspension groove. This avoids the vibration of the peristaltic tube caused by the periodic squeezing and releasing of the rollers during the operation of the peristaltic pump, and solves the problem of decreased dripping accuracy.

[0016] 2. This design provides an auxiliary device for fixing the dripping peristaltic pump tube. By setting up auxiliary mechanisms (including mounting holes, mounting plates, fixing bolts, and protective sleeves), the fixing bolts and mounting holes are interlocked and fixed, and the protective sleeves and mounting plates are fixedly connected. This allows the mounting plate to be firmly installed on the left end of the pump body by the fixing bolts, and the protective sleeves to be stably fitted over the peristaltic tube. Thus, this device can protect the peristaltic tube through the protective sleeve and offset the pulling force through the mounting plate, preventing the peristaltic tube from shifting due to the pulling force at both ends during dripping, and solving the problem of leakage caused by poor sealing at the pump tube and joint.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution for an auxiliary device for fixing a dripping peristaltic pump tube: it includes a pump body 1, and a traction mechanism is fixedly connected inside the pump body 1. The traction mechanism includes a guide groove 3, an adjusting push rod 301, a movable seat 3011, a guide slider 3012, a connecting frame 3013, a suspension groove 3014, and a guide spring 3015. The guide groove 3 is opened at the front end of the pump body 1. The adjusting push rod 301 is fixedly installed in the guide groove 3. The movable seat 3011 is slidably installed in the guide groove 3. The guide slider 3012 is fixedly installed on the outer wall of the movable seat 3011. One side of the movable seat 3011 abuts against the output end of the adjusting push rod 301. By setting a traction mechanism including the guide groove 3, adjusting push rod 301, movable seat 3011, and guide slider 3012 inside the pump body 1, a basic structural support can be provided for the subsequent positioning of the peristaltic tube 2013, and the initial traction and guidance effect of the peristaltic tube 2013 and related components can be achieved.

[0026] The connecting frame 3013 is fixedly mounted on the front end of the movable seat 3011. The suspension groove 3014 is opened on the front end of the connecting frame 3013. The adjusting push rod 301 is used to limit the rebound position of the movable seat 3011. By fixing the connecting frame 3013 to the front end of the movable seat 3011, opening the suspension groove 3014 on the connecting frame 3013, and using the adjusting push rod 301 to limit the rebound position of the movable seat 3011, the position of the movable seat 3011 can be stabilized, thereby providing a more accurate suspension positioning point for the peristaltic tube 2013 and preventing the positioning deviation caused by the rebound of the movable seat 3011.

[0027] A drive mechanism is installed on the rear side of the pump body 1. The drive mechanism includes a servo motor 2, a turntable 201, and a mounting bracket 2011. The servo motor 2 is fixedly installed on the rear side of the pump body 1, and the turntable 201 is fixedly installed on the outer wall of the front output shaft of the servo motor 2. By installing the drive mechanism consisting of the servo motor 2, the turntable 201, and the mounting bracket 2011 on the rear side of the pump body 1, a power basis is provided for the extrusion and conveying of the peristaltic tube 2013, which can drive the relevant components to realize the extrusion action of the peristaltic tube 2013.

[0028] The mounting frame 2011 is fixedly installed on the outer wall of the turntable 201. The driving mechanism also includes a squeezing roller 2012 and a peristaltic tube 2013. The squeezing roller 2012 is rotatably installed in the mounting frame 2011, and the peristaltic tube 2013 is embedded in the front groove of the pump body 1. By fixing the mounting frame 2011 to the outer wall of the turntable 201 and installing the squeezing roller 2012 in the mounting frame 2011, while allowing the peristaltic tube 2013 to be embedded in the front groove of the pump body 1, the squeezing roller 2012 can stably act on the peristaltic tube 2013, ensuring the stability of the squeezing and conveying.

[0029] The servo motor 2, turntable 201, mounting frame 2011, and extrusion roller 2012 together form the extrusion structure for the peristaltic tube 2013. The extrusion structure composed of the servo motor 2, turntable 201, mounting frame 2011, and extrusion roller 2012 can periodically extrude the peristaltic tube 2013 to achieve a stable fluid delivery effect.

[0030] An auxiliary mechanism is provided inside the pump body 1. The auxiliary mechanism includes an outlet hole 101 and a mounting hole 1011. The outlet hole 101 is opened inside the pump body 1, and the mounting hole 1011 is opened at the left end of the pump body 1. The auxiliary mechanism containing the outlet hole 101 and the mounting hole 1011 inside the pump body 1 provides a channel for the outlet of the peristaltic tube 2013 and the installation of the device, which facilitates the arrangement of the peristaltic tube 2013 and the connection of the device with other components.

[0031] Furthermore, the auxiliary mechanism includes a mounting plate 1012, a fixing bolt 1013, and a protective sleeve 1014. The mounting plate 1012 is fitted to the left end of the pump body 1, and the mounting plate 1012 also has mounting holes 1011 inside. By fitting the mounting plate 1012 with mounting holes 1011 to the left end of the pump body 1, the number of mounting and fixing points on the left end of the device can be increased, providing stable support for the subsequent installation of the protective sleeve 1014.

[0032] The fixing bolt 1013 is installed inside the mounting plate 1012 and the pump body 1. The protective sleeve 1014 is fixedly installed at the end of the mounting plate 1012 away from the pump body 1. The peristaltic tube 2013 is inserted into the protective sleeve 1014. The fixing bolt 1013 is installed inside the mounting plate 1012 and the pump body 1. The protective sleeve 1014 is fixed at the end of the mounting plate 1012 away from the pump body 1. The peristaltic tube 2013 is inserted into the protective sleeve 1014, which can fix the mounting plate 1012 and protect the peristaltic tube 2013 from external wear, while enhancing the installation stability of the peristaltic tube 2013.

[0033] The working principle of this utility model is as follows: In use, firstly, the peristaltic tube 2013 is embedded into the groove at the front end of the pump body 1 to ensure that the position of the peristaltic tube 2013 is compatible with the subsequent extrusion structure; then, the mounting plate 1012 is placed against the left end of the pump body 1, so that the mounting hole 1011 on the mounting plate 1012 is aligned with the mounting hole 1011 on the left end of the pump body 1; then, the fixing bolt 1013 is inserted into the aligned mounting hole 1011 to achieve a fixed connection between the mounting plate 1012 and the pump body 1; finally, the end of the peristaltic tube 2013 away from the pump body 1 is inserted into the protective sleeve 1014 on the mounting plate 1012 to complete the initial fixing and protection of the peristaltic tube 2013, while the outlet hole 101 in the pump body 1 is reserved as a channel for subsequent fluid transportation;

[0034] Then, the adjusting push rod 301 is activated, and the output end of the adjusting push rod 301 applies a pushing force to the moving seat 3011, pushing the moving seat 3011 to slide along the inner wall of the guide groove 3. During this process, the guide slider 3012 fixed on the outer wall of the moving seat 3011 slides synchronously along the corresponding trajectory of the guide groove 3. Through the sliding cooperation between the guide slider 3012 and the guide groove 3, the sliding direction of the moving seat 3011 is restricted, and the moving seat 3011 is prevented from deviating. When the moving seat 3011 slides to the preset position that matches the positioning requirements of the peristaltic tube 2013, the adjusting push rod 301 maintains the pushing force at the output end, restricting the moving seat 3011 from rebounding under the elastic force of the guide spring 3015. At this time, the connecting frame 3013 fixed at the front end of the moving seat 3011 is positioned synchronously with the moving seat 3011. The suspension groove 3014 opened at the front end of the connecting frame 3013 is precisely fitted with the corresponding part of the peristaltic tube 2013, providing stable suspension support for the peristaltic tube 2013.

[0035] Then, the servo motor 2 is started, and the front output shaft of the servo motor 2 drives the turntable 201 fixed thereto to rotate at a constant speed. The mounting bracket 2011 fixed on the outer wall of the turntable 201 moves in a circular motion synchronously with the turntable 201. During the circular motion, the squeezing roller 2012, which is rotated inside the mounting bracket 2011, periodically contacts the peristaltic tube 2013 embedded in the groove of the pump body 1 and applies squeezing force. When the squeezing roller 2012 squeezes the peristaltic tube 2013, the fluid inside the peristaltic tube 2013 flows in a preset direction under the action of squeezing force. When the squeezing roller 2012 rotates with the turntable 201 and disengages from the peristaltic tube 2013, the peristaltic tube 2013 returns to its original shape under its own elasticity, thus completing the suction of fluid. Through the periodic squeezing and releasing of the peristaltic tube 2013 by the squeezing roller 2012, the continuous and stable drip delivery of fluid is achieved.

[0036] Throughout the dripping process, the traction mechanism remains operational. The adjusting push rod 301 continuously restricts the rebound of the moving seat 3011, the guide slider 3012 maintains the stable position of the moving seat 3011, and the suspension groove 3014 on the connecting frame 3013 continuously positions and constrains the peristaltic tube 2013 to prevent the peristaltic tube 2013 from vibrating due to the periodic force of the squeezing roller 2012. At the same time, the protective sleeve 1014 continuously wraps the exposed part of the peristaltic tube 2013 to reduce damage to the peristaltic tube 2013 from external friction. The mounting plate 1012 is firmly connected to the pump body 1 through the fixing bolt 1013 to counteract the pulling force generated at both ends of the peristaltic tube 2013 due to fluid transportation, prevent the peristaltic tube 2013 from shifting, and ensure dripping accuracy and sealing performance.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
