[0028] Such as Figures 1 to 5As shown in the figure, a luer connector of the present utility model includes: a luer connector body 1, an adjusting mechanism for adjusting the flow rate of the luer connector body 1, and a connecting mechanism for facilitating the installation and disassembly of the luer connector body 1.

[0029] The connecting mechanism includes: an internal thread tube 10, a clamping plate 15 arranged inside the internal thread tube 10, a linkage assembly for driving the clamping plate 15 to move, and a guiding assembly for guiding the movement of the clamping plate 15; the linkage assembly includes: an external thread tube 11 threadedly connected to the internal thread tube 10, and a collar 12 fixedly sleeved on the external thread tube 11; the guiding assembly includes: a fixed ring 13 fixedly installed inside the internal thread tube 10, a guiding groove opened on the fixed ring 13, a linkage block 16 slidably installed in the guiding groove, a guiding rod 17 for limiting the movement of the linkage block 16, both ends of the guiding rod 17 are fixedly connected to the inner wall of the guiding groove, a linkage spring 18 sleeved on the guiding rod 17, one end of the linkage spring 18 is fixedly connected to the linkage block 16, the other end of the linkage spring 18 is fixedly connected to the inner wall of the guiding groove, and a linkage rod 14 fixedly installed with the linkage block 16; the clamping plate 15 is fixedly connected to the linkage rod 14; one side of the linkage rod 14 is inclined, and one end of the external thread tube 11 close to the internal thread tube 10 is inclined; the clamping plate 15 is arc-shaped, and at least two clamping plates 15 are provided.

[0030] One end of the pipe fitting to be connected is sequentially passed through the inner cavities of the external thread tube 11 and the internal thread tube 10, and inserted into the second connecting pipe 5, thereby realizing the connection between the pipe fitting and the second connecting pipe 5. At this time, by rotating the collar 12, the collar 12 drives the external thread tube 11 to rotate. Since the internal thread tube 10 and the external thread tube 11 are threadedly connected, the external thread tube 11 enters the inner cavity of the internal thread tube 10 while rotating. When the inclined surface of the external thread tube 11 abuts against the inclined surface of the linkage rod 14, it can drive the linkage rod 14 to move. At this time, the linkage rod 14 drives the linkage block 16 to slide in the inner cavity of the guiding groove, and drives the linkage spring 18 to be compressed. Through the guiding and limiting of the guiding rod 17 and the guiding groove on the linkage rod 14, the linkage rod 14 moves along the axial direction of the guiding rod 17. Furthermore, when the inclined surface of the external thread tube 11 abuts against the inclined surface of the linkage rod 14, it can drive a plurality of clamping plates 15 to move along the axial direction of the adjacent guiding rod 17, that is, the plurality of clamping plates 15 approach each other, so as to clamp and fix the pipe fitting. And as the external thread tube 11 gradually squeezes the linkage rod 14, the clamping plate 15 gradually clamps the pipe fitting. After clamping the pipe fitting, stop rotating the external thread tube 11, thereby realizing the rapid installation between the luer connector body 1 and the pipe fitting, with simple operation and improved installation efficiency.

[0031] When it is necessary to disassemble the Luer connector body 1 from the pipe fitting, the collar 12 can be rotated in the reverse direction. The collar 12 drives the external-threaded pipe 11 to rotate in the reverse direction, so that the external-threaded pipe 11 gradually moves out of the internal-threaded pipe 10. As a result, the external-threaded pipe 11 no longer exerts a squeezing effect on the linkage rod 14. At this time, the elastic force of the linkage spring 18 can drive the linkage block 16 to reset. The linkage block 16 drives the linkage rod 14 to reset, and the linkage rod 14 drives the clamping plate 15 to reset. At this time, the clamping plate 15 releases the clamping and fixing of the pipe fitting, so that the pipe fitting can be taken out from the internal-threaded pipe 10, thereby realizing the rapid disassembly between the Luer connector body 1 and the pipe fitting. The operation is simple and the disassembly efficiency is improved.

[0032] In this application, through the setting of the connection mechanism, the rapid installation and disassembly between the Luer connector body 1 and the pipe fitting can be realized. The operation is simple, the installation and disassembly efficiency is improved, and the problem that the connection of an existing Luer connector is very inconvenient during use, and it is not convenient to disassemble and clean later, resulting in poor practicability and affecting the actual use is solved.

[0033] It should be added here that through the setting of the linkage block 16, the guide rod 17, and the linkage spring 18, on the one hand, the clamping plate 15 can be guided and limited to prevent the clamping plate 15 from shifting when moving, and on the other hand, when disassembling, the clamping plate 15 can be driven to reset to prepare for subsequent use.

[0034] The adjustment mechanism includes: a first connecting pipe 3 communicated with the Luer connector body 1, an elastic hose 4 communicated with the first connecting pipe 3, a second connecting pipe 5 communicating the elastic hose 4 and the internal-threaded pipe 10, and an extrusion assembly for extruding the elastic hose 4; the extrusion assembly includes: a sleeve 2 fixedly sleeved on the first connecting pipe 3 and the second connecting pipe 5, a second extrusion plate 9 and a first extrusion seat 6 for extruding the elastic hose 4, and a moving unit for driving the second extrusion plate 9 to move; the moving unit includes: a threaded rod 7 threadedly connected to the sleeve 2, a rotating plate 8 fixedly installed at one end of the threaded rod 7; the other end of the threaded rod 7 is rotatably connected to the second extrusion plate 9.

[0035] When adjusting the flow rate of the Luer connector body 1, by rotating the rotating plate 8, the rotating plate 8 drives the threaded rod 7 to rotate. Since the threaded rod 7 is threadedly connected to the sleeve 2, the threaded rod 7 rotates and moves downward at the same time. The threaded rod 7 drives the second extrusion plate 9 to move downward. The second extrusion plate 9 extrudes the elastic hose 4. Through the mutual cooperation of the second extrusion plate 9 and the first extrusion seat 6, the elastic hose 4 can be deformed by extrusion, so that the flow rate of the liquid in the elastic hose 4 is reduced, thereby realizing the function of adjusting the flow rate of the Luer connector body 1, and further realizing the control of the infusion flow rate, meeting different infusion requirements, and improving the applicability.

[0036] Working principle: When in use, one end of the pipe fitting to be connected is sequentially passed through the inner cavities of the external thread pipe 11 and the internal thread pipe 10, and inserted into the second connecting pipe 5, thereby realizing the connection between the pipe fitting and the second connecting pipe 5. At this time, by rotating the collar 12, the collar 12 drives the external thread pipe 11 to rotate. Since the internal thread pipe 10 and the external thread pipe 11 are in threaded connection, the external thread pipe 11 enters the inner cavity of the internal thread pipe 10 while rotating. When the inclined surface of the external thread pipe 11 abuts against the inclined surface of the linkage rod 14, it can drive the linkage rod 14 to move. At this time, the linkage rod 14 drives the linkage block 16 to slide in the inner cavity of the guiding groove, and drives the linkage spring 18 to be compressed. Through the guiding and limiting of the guiding rod 17 and the guiding groove on the linkage rod 14, the linkage rod 14 moves along the axial direction of the guiding rod 17. Furthermore, when the inclined surface of the external thread pipe 11 abuts against the inclined surface of the linkage rod 14, it can drive a plurality of clamping plates 15 to move along the axial direction of the adjacent guiding rods 17, that is, the plurality of clamping plates 15 approach each other, thereby clamping and fixing the pipe fitting. And as the external thread pipe 11 gradually squeezes the linkage rod 14, the clamping plates 15 gradually clamp the pipe fitting. After clamping the pipe fitting, stop rotating the external thread pipe 11, thereby realizing the rapid installation between the Luer connector main body 1 and the pipe fitting, with simple operation and improved installation efficiency; when it is necessary to disassemble the Luer connector main body 1 and the pipe fitting, the collar 12 can be rotated in the reverse direction, and the collar 12 drives the external thread pipe 11 to rotate in the reverse direction, so that the external thread pipe 11 gradually moves out of the internal thread pipe 10. Furthermore, the external thread pipe 11 no longer has an extrusion effect on the linkage rod 14. At this time, the elastic force of the linkage spring 18 can drive the linkage block 16 to reset, the linkage block 16 drives the linkage rod 14 to reset, and the linkage rod 14 drives the clamping plates 15 to reset. At this time, the clamping plates 15 release the clamping and fixing of the pipe fitting, so that the pipe fitting can be taken out from the internal thread pipe 10, thereby realizing the rapid disassembly between the Luer connector main body 1 and the pipe fitting, with simple operation and improved disassembly efficiency.
