Technical Field

[0001] The utility model belongs to the field of extension tubes, in particular to a multi-channel micro pump extension tube. Background Art

[0002] The micro pump extension tube is an auxiliary tool used for injection, nursing and protective equipment. Its main function is to extend the injection pipeline of the micro pump so that drugs or liquids can be delivered to a distant site. By connecting the micro pump and the extension tube, medical staff can perform injection operations more conveniently and flexibly.

[0003] The extension tube of the micro pump is usually a plurality of integrated pipes fixed together, and the staff need to find the two ends of the same pipe to connect, which greatly increases the difficulty of the staff's work. In addition, the extension tube is easy to get tangled during use, affecting its use. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a multi-channel micro pump extension tube.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a multi-channel micro pump extension tube, comprising a symmetrically arranged shell, two ends of the shell are rotatably provided with turntables, and the other end of the shell is provided with a conversion assembly that is interlocked;

[0006] The conversion assembly includes an upper buckle ring and a lower buckle ring, a connecting plate is rotatably provided inside the upper buckle ring, a spring is installed between the connecting plate and the lower buckle ring, the upper buckle ring is connected to the outer shell on one side through an upper clamping block, and the lower buckle ring is installed on the outer shell on the other side through a lower clamping block, a lower connecting block is also fixed inside the lower clamping block, at least two groups of valve cores are provided in the lower connecting block, an upper connecting block is fixed inside the upper buckle ring, and at least two racks are fixed to an end face of the upper connecting block close to one side of the lower connecting block, and the valve core is driven to rotate by the racks.

[0007] Optionally, the upper buckle ring and the lower buckle ring are both L-shaped, and the connecting plate rotates on the upper buckle ring.

[0008] Optionally, the valve core includes a ball core and a gear, at least two valve holes are opened in the lower connecting block, the ball core is located in the valve hole, the gear rotates in the lower connecting block, and the lower connecting block is meshed with the rack.

[0009] Optionally, at least two connecting holes are opened in the upper connecting block, the number of the connecting holes corresponds to the valve core, and a sealing ring is installed on one end surface of the upper connecting block close to the lower connecting block. The sealing ring is located at the connecting hole and abuts against the valve core.

[0010] Optionally, the end surface of the connecting plate is arranged in an arc shape, and the connecting plate is curved, and the end surface of the connecting plate is provided with teeth.

[0011] Optionally, the turntable is also provided with at least two through holes, and at least two extension tubes are installed between the turntable and the upper connecting block and the lower connecting block.

[0012] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Due to the setting of the swivel assembly, any two extension tubes in the two sets of extension tubes can be connected at will through the two separate sets of extension tubes, so there is no need to deliberately connect the corresponding extension tubes. After directly connecting the extension tubes, the upper buckle ring and the lower block can still be adjusted to connect the disconnected extension tubes.

[0014] 2. Through the rotatable turntable, the upper clamp block and the lower clamp block, the extension tube in the shell can be effectively prevented from getting entangled and blocking the pipeline, thereby affecting its use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0022] As shown in Figures 1-5, a multi-channel micropump extension tube includes a symmetrically arranged shell 10, and a turntable 23 is rotatably provided at both ends of the shell 10. The other end of the shell 10 is provided with a conversion component that is interlocked, and the conversion component includes an upper buckle ring 12 and a lower buckle ring 14. A connecting plate 20 is rotatably provided inside the upper buckle ring 12. The end face of the connecting plate 20 is arranged in an arc shape, and the connecting plate 20 is curved. The end face of the connecting plate 20 is provided with teeth. The upper buckle ring 12 and the lower buckle ring 14 are both arranged in an L shape. The connecting plate 20 rotates on the upper buckle ring 12, and a spring is installed between the connecting plate 20 and the lower buckle ring 14. The upper buckle ring 12 is connected to one side of the shell 10 through an upper clamping block 15, and the lower buckle ring 14 is installed on the other side of the shell 10 through a lower clamping block 13. The lower clamping block 1 A lower connecting block 16 is also fixed inside, and at least two groups of valve cores are arranged in the lower connecting block 16. An upper connecting block 17 is fixed inside the upper buckle ring 12. At least two racks 22 are fixed on the end surface of the upper connecting block 17 close to the lower connecting block 16. The valve core is driven to rotate by the racks 22. The valve core includes a ball core 18 and a gear 19. At least two valve holes are opened in the lower connecting block 16. The ball core 18 is located in the valve hole. The gear 19 rotates in the lower connecting block 16. The lower connecting block 16 is meshed with the rack 22. At least two connecting holes 21 are opened in the upper connecting block 17. The number of the connecting holes 21 corresponds to the valve core. A sealing ring is installed on the end surface of the upper connecting block 17 close to the lower connecting block 16. The sealing ring is located at the connecting hole 21 and abuts against the valve core.

[0023] At least two through holes are also provided on the rotating disk 23 , and at least two extension tubes 11 are installed between the rotating disk 23 and the upper connecting block 17 and the lower connecting block 16 .

[0024] When in use, an extension tube is added to the pipeline of the micro pump, and the extension tubes 11 on both sides of the shell 10 can be directly and arbitrarily connected. After the connection is completed, the upper buckle ring 12 and the lower clamping block 13 can be rotated in opposite directions. At this time, the upper buckle ring 12 and the lower buckle ring 14 can rotate relative to each other, which will drive the lower connecting block 16 and the upper connecting block 17 to rotate, so that the rack 22 can rotate relative to the lower connecting block 16 as a reference. The rotation of the rack 22 will engage with the gear 19. Since the rack 22 is arranged in an arc shape, continued rotation will cause the upper connecting block 17 and the lower connecting block 16 to separate to both sides. At this time, the ball core 18 is disengaged from the connection hole 21, and then the rack 22 will drive the gear 19 to rotate, so that the ball core 18 can temporarily close the pipeline, and then continue to rotate to connect the two different extension tubes 11, and continue to adjust the connected extension tubes 11 until the two extension tubes 11 connected to the micro pump are connected. At this time, the micro pump can be used, and the difficulty of manual docking is reduced.

[0025] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
