[0030] Figure 1 It is a three-dimensional schematic diagram of an embodiment of the pipeline quick connector of the utility model.
[0031] like Figure 1 As shown in the embodiment, the pipeline quick connector of the utility model includes a male connector 1 and a female connector 2, and the male connector 1 and the female connector 2 can be quickly sealed and docked. Optionally, the male connector 1 and the female connector 2 are both made of polysulfone, which can withstand temperatures of -40°C to 149°C, and are not easily damaged or deformed during high-temperature sterilization, such as 50K gamma radiation sterilization. Moreover, the polysulfone material is light and easy to place, which can match the direction of the infusion pipeline and reduce the weight of the quick connector of the entire infusion device. The quick connector made of polysulfone is also corrosion-resistant and can transport various corrosive liquids. In an optional embodiment, the material of the male connector 1 and the female connector 2 is not limited, and can also be glass or stainless steel.
[0032] Specifically, the male connector 1 has a mutually connected docking portion 18 and a pipe connecting portion 3, and the docking portion 18 can extend into the interior of the female connector 2 and seal with the female connector 2. The pipe connecting portion 3 includes a connecting end 31 and a connecting pipe 32. When in use, the infusion pipe can be sleeved on the connecting end 31 and the connecting pipe 32, and the infusion pipe can be a rubber hose.
[0033] exist Figure 1 In the embodiment, optionally, the connection end 31 is shaped as a truncated cone, and the outer diameter of the connection end 31 gradually decreases from the connection with the connecting tube 32. When the infusion pipeline is installed, it can be conveniently inserted from the small outer diameter port of the connection end 31 and gradually expanded until the entire pipeline connecting part 3 is installed.
[0034] like Figure 1 In the embodiment, optionally, the outer surfaces of the connecting end 31 and the connecting tube 32 can be provided with threads 33, and the threads 33 can improve the tightness of the connection with the inner surface of the infusion pipeline, and at the same time increase the friction with the inner surface of the infusion pipeline to fix the position of the infusion pipeline and prevent the infusion pipeline from moving and falling off during the infusion process, causing liquid leakage in the infusion pipeline.
[0035] In the embodiment shown in the figure, there are two types of threads, one is a thread radially evenly distributed on the connection end 31, and the other is a circumferential raised thread provided in the middle of the connection pipe 32, and the raised thread 33 can fix the position of the infusion pipe sleeve. When the infusion pipe is sleeved on the pipe connection part 3, a tie band can be provided, and the tie band is used to tighten the rubber hose to prevent the rubber hose from falling off and causing liquid leakage in the infusion pipe. The tie band can tighten the infusion pipe near the raised thread, and the raised thread can fix the tightening position of the tie band and tighten it, further preventing the infusion pipe from loosening or even falling off due to accidental touch during the infusion process, causing liquid leakage.
[0036] In other embodiments, the radially uniformly distributed threads and the raised threads can be arranged at the connecting end 31 and / or the connecting tube 32 according to actual conditions, as long as the infusion pipeline can be prevented from falling off.
[0037] In another embodiment, the outer surfaces of the connecting end 31 and the connecting pipe 32 may also be smooth surfaces without threads, so as to facilitate the smooth installation of the hose on the pipe connecting portion 3 .
[0038] The female connector 2 has interconnected docking spaces 28 (such as Figure 2 The butt joint space 28 is used to accommodate the male connector 1 and seal with the butt joint 18 of the male connector 1. The shape, structure and function of the pipe connection part 3 of the female connector 2 are the same as those of the male connector 1, and will not be repeated here.
[0039] exist Figure 1In the embodiment, the pipe connection portion of the female connector 2 has the same inner diameter as the pipe connection portion 3 of the male connector, and the inner diameter of the docking portion 18 of the male connector 1 is also the same as the inner diameter of the pipe connection portion 3, so that the flow rate and pressure of the liquid in the male connector 1 can be maintained, and when the male connector 1 is extended into the female connector 2 for docking, it can directly dock with the pipe connection portion of the female connector 2.
[0040] As can be seen from the figure, the female connector interface end 20 is provided with a protective cover 22, and an elastic locking mechanism 21 (such as Figure 2 As shown in the figure), the elastic locking mechanism 21 is used to clamp or disconnect the docking portion 18 of the female connector 2 and the male connector 1. The elastic locking mechanism 21 can quickly and conveniently realize the docking and disconnection of the male connector 1 and the female connector 2.
[0041] The protective cover 22 is arranged on the outside of the elastic locking mechanism 21 and is clamped on the docking space 28 of the female connector 2 and the outer surface of the interface end 20, so as to prevent the elastic locking mechanism 21 from loosening due to pressure during high-temperature sterilization, and to prevent the staff from accidentally touching the elastic locking mechanism 21 during the infusion process, so as to disconnect the male connector 1 and the female connector 2, resulting in leakage and contamination of the transported liquid.
[0042] Figure 2 The figure is a schematic diagram of a female connector of an embodiment of a pipe quick connector of the present utility model.
[0043] from Figure 2 It can be clearly seen from the embodiment that the female connector 2 includes a pipeline connection portion 3, a docking space 28 and an interface end 20 which are interconnected in sequence. The inner diameter of the docking space 28 is larger than the inner diameter of the pipeline connection portion 3, and the inner diameter of the interface end 20 is larger than the inner diameter of the docking space 28. The interior of the docking space 28 is suitable for accommodating the docking portion 18 of the male connector 1, and the docking space 28 is flush with the pipeline interface of the pipeline connection portion 3, so that the interface end 11 of the male connector can directly abut the pipeline connection portion 3 of the female connector 2, so that the liquid transported in the pipeline can directly flow from the pipeline connection portion 3 of the female connector 2 into the interior of the male connector 1.
[0044] The larger interface end 20 can facilitate the insertion of the docking portion 18 of the male connector 1 , and an elastic locking mechanism 21 can be provided at the interface end 20 , and a limiting portion 23 is provided on the outer surface of the docking space 28 .
[0045] As shown in the figure, the cross section of the limiting portion 23 is a triangle, and one side of the triangle is installed on the outer surface of the docking space 28, so that the corner corresponding to the side protrudes from the outer surface of the docking space.
[0046] In an optional embodiment, the limiting portion 23 may be a triangular body, or may be composed of two parallel triangular pieces spaced apart from each other, thereby saving materials for making the limiting portion 23 and making the quick connector lighter.
[0047] In other embodiments, the shape of the limiting portion 23 is not limited, and may be, for example, a flange, a bump, etc., as long as it can serve as a fulcrum for the deformation of the elastic sheet 24 .
[0048] According to the embodiment shown in the figure, the elastic locking mechanism 21 includes an elastic sheet 24 having a first end 27 abutting against the limiting portion 23, a pressing portion 25 connected to the second end 29 of the elastic sheet 24, and a clamping portion 26 connected to the pressing portion 25. Specifically, the first end 27 of the elastic sheet 24 abuts against a protruding corner of the limiting portion 23, so that the elastic sheet 24 can be deformed with the protruding corner of the limiting portion 23 as a fulcrum.
[0049] In the embodiment shown in the figure, optionally, the elastic sheet 24 is wedge-shaped, and the narrower end of the wedge is the first end 27, which is used to abut the limiting portion 23; the wider end of the wedge is the second end 29, which is used to connect with the pressing portion 25. The wedge shape of the elastic sheet has a larger deformation amount and can enhance the strength of the elastic sheet, making it more durable.
[0050] The female connector interface end 20 is provided with a notch (not shown in the figure) corresponding to the elastic sheet 24. When the elastic sheet 24 is subjected to external pressure, the second end 29 of the elastic sheet 24 is deformed with the first end 27 as a fulcrum to enter the notch.
[0051] Specifically, the clamping portion 26 is provided with a through hole (not shown in the figure) with the same inner diameter as the female connector interface end 20 . The portion of the clamping portion 26 opposite to the pressing portion 25 is wider than other portions and is embedded in the female connector interface end 20 .
[0052] The clamping portion 26 has a first position and a second position. In the first position, the through hole of the clamping portion 26 deviates from the inner periphery of the female connector interface end 20, and its wider part protrudes from the inner periphery of the female connector interface end 20, for clamping and locking the male connector 1 extending into the docking space 28.
[0053] In the second position, the clamping portion 26 moves radially, and its through hole coincides with and communicates with the inner circumference of the female connector interface end 20 , thereby facilitating the connection or disconnection of the male connector 1 .
[0054] As can be seen from the figure, the pressing part 25 has a pressing panel 251 and a limiting part 252 connected between the pressing panel 251 and the clamping part 26. When the pipe joint is connected or disconnected, the clamping part 26 can be driven to move radially by applying force to the pressing panel 251. At this time, the elastic sheet 24 is forced to bend with the limiting part 23 as a fulcrum to enter the notch of the female connector interface end 20 until the limiting part 252 abuts against the outer edge of the female connector interface end 20. At this time, the clamping part 26 is in the second position, that is, the through hole and the inner periphery of the female connector interface end 20 are overlapped and communicated, and the male connector 1 can be connected or disconnected. Release the force on the pressing panel 251, and due to the elastic force of the elastic sheet 24, the pressing part 25 drives the clamping part 26 to return to the first position.
[0055] Combination Figure 1 It can be seen that the elastic locking mechanism 21 has a protective cover 22, which prevents the male connector 1 and the female connector 2 from being separated due to the excessive air pressure in the infusion pipeline squeezing the clamping part 26 during high-temperature sterilization, and prevents the male connector 1 and the female connector 2 from being disconnected due to accidental touch by the staff during production or experiments.
[0056] Figure 3 The figure is a schematic diagram of a male connector of an embodiment of a pipe quick connector of the utility model.
[0057] Combination Figure 1 It can be seen that the docking portion 18 of the male connector 1 has a fixing groove 15, a connecting portion 12 and an interface end 11 which are sequentially connected to the pipe connecting portion 3 of the male connector 1. The interface end 11 and the connecting portion 12 are used to extend into the docking space 28 of the female connector 2, and the fixing groove 15 is used to extend into the female connector interface end 20, so as to achieve docking and locking with the female connector 2.
[0058] Specifically, a sealing flange 16 is provided at the connection between the fixing groove 15 and the pipe connection part 3, and the sealing flange 16 is used to seal the female joint interface end 20 to prevent leakage of liquid transported in the pipes of the male joint 1 and the female joint 2. The fixing groove 15 has circumferentially uniformly distributed calibration protrusions 17 near the sealing flange 16, and the calibration protrusions 17 are used for docking calibration between the fixing groove 15 and the female joint interface end 20 during docking.
[0059] A clamping flange 14 is provided at the connection between the connection portion 12 and the fixing groove 15, and the clamping flange 14 is used to clamp with the clamping portion 26 of the female connector, thereby locking the male connector 1 and the female connector 2. Furthermore, the outer surface of the connection portion 12 is evenly and circumferentially distributed with calibration ridges 13 arranged along the axial direction, and the calibration ridges 13 are used for calibration when the connection portion 12 and the docking space 28 of the female connector are docked, and can guide the clamping portion 26 to move along the calibration ridges 13 until it passes through the clamping flange 14 and is clamped and locked at the fixing groove 15.
[0060] As can be seen from the embodiment in the figure, the fixing groove 15 is provided with a sealing ring near the clamping flange 14, which further prevents leakage of the transported liquid in the pipeline quick connector. As shown in the figure, the male connector interface end 11 is provided with a groove, and the groove is used to embed the sealing ring 4, which is sealed from the docking port 11 of the male connector to prevent leakage of the transported liquid.
[0061] Since the male connector 1 can be easily connected to the inside of the female connector 2 and can be easily disconnected and removed, when the sealing ring 4 at the male connector interface end 11 and the fixing groove 15 near the clamping flange 14 is damaged, the staff can promptly discover and replace it, thereby ensuring the airtightness of the pipeline quick connector when conveying liquids.
[0062] It can also be seen from the figure that the outer diameter of the connecting portion 12 is the same as the outer diameter of the fixing groove 15, and is smaller than the outer diameter of the male connector interface end 11, so as to facilitate the setting of the calibration edge 13. A transition angle is set at the connection between the connecting portion 12 and the male connector interface end 11 to facilitate the connection of the calibration edge 13.
[0063] Optionally, the axial length of the fixing groove 15 is the same as the axial length of the calibration portion 12, so that the entire pipeline quick connector is small in size and light, and is convenient for quick connection or disconnection.
[0064] Combination Figure 2 It can be seen that when connected, the male connector 1 extends from the female connector interface end 20, and interacts with the clamping portion 26 inside the female connector interface end 20, that is, the clamping portion 26 is guided by the calibration edge 13 of the male connector to the clamping flange 14, and the clamping portion 26 is located in the second position. At the same time, the clamping portion 26 moves in the radial direction opposite to the pressing portion 25, and drives the pressing portion 25 to move radially, and the elastic sheet 24 is deformed accordingly, until the clamping flange 14 of the male connector 1 passes through the clamping portion 26 and enters the docking space 28.
[0065] At this time, the clamping portion 26 is located in the fixing groove 15 of the male connector 1, and the clamping portion 26 is not subjected to force in the fixing groove 15, and due to the elastic force of the elastic sheet 24, it returns to the first position, that is, the clamping portion 26 protrudes from the inner periphery of the interface end 20 of the female connector to clamp and lock the clamping flange 14 of the male connector 1, thereby locking the male connector 1.
[0066] At this time, the male connector interface end 11 abuts against the pipe interface of the pipe connecting portion 3 of the female connector within the docking space 28 of the female connector, and the sealing flange 16 of the male connector closes the female connector interface end 20 .
[0067] Finally, the protective cover 22 is placed on the elastic locking mechanism 21, thereby completing the quick connection between the male connector and the female connector and the locking protection.
[0068] When disconnecting, unlock the protective cover 22, press the pressing part 25 of the elastic locking mechanism 21, and push the limiting part 23 to move radially to the first position, that is, the through hole of the limiting part 23 coincides with the inner diameter of the female connector interface end 20, and the quick connector 1 can be pulled out at this time.
[0069] The pipe quick connector of the utility model is light and small in size, and can be easily connected or disconnected. The small-volume pipe quick connector can reduce the friction area between the male connector and the female connector, thereby reducing the loss caused by friction. Moreover, the pipe quick connector of the utility model adopts polysulfone material, which can further prevent the pipe quick connector from being damaged, so that the pipe can withstand high-temperature sterilization, and is corrosion-resistant and can transport chemical reagents such as acids, alkalis, and salts. The pipe quick connector of the utility model can facilitate the replacement of the sealing rings by setting two layers of sealing rings on the male connector, further preventing the leakage of the transported liquid.
[0070] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the concept of the present invention, and these deformations and modifications should all fall within the scope of the present invention.
