Detailed Description
The utility model will be further described with reference to examples of embodiments shown in the drawings to which:
example 1
As shown in fig. 1-6, a novel connection structure of a syringe and a micropump comprises a syringe 1, a micropump connection pipe 2 and a reinforcement member 3, wherein a liquid outlet 4 on the syringe 1 is sleeved in a liquid inlet 5 on the micropump connection pipe 2, and the liquid outlet 4 is in interference fit with the liquid inlet 5. The cover is equipped with elastic ring 6 on syringe 1, interference fit between elastic ring 6 and syringe 1, fixed spacing ring 7 that is equipped with on micropump connecting pipe 2, reinforcement 3 includes the lantern ring 8 of loop configuration, and 8 covers of lantern ring are established outside the junction between syringe 1 and the micropump connecting pipe 2, 8 one end of the lantern ring is fixed and is equipped with towards the ring board 9 of 8 inboard extensions of lantern ring, ring board 9 with spacing ring 7 is back of the body to the side laminating of syringe 1, 8 inboard of the lantern ring be equipped with 6 complex annular groove 10 of elastic ring, 6 imbeds in the annular groove 10.
Two sides of one of the split parts are fixedly provided with clamping teeth 14, two sides of the other split part are respectively provided with a clamping groove 15, the clamping teeth 14 correspond to the clamping grooves 15 one by one, and the clamping teeth 14 are embedded into the corresponding clamping grooves 15.
When the utility model is used, the elastic ring 6 is firstly sleeved on the injector 1, the elastic ring 6 is tightly sleeved on the injector 1 under the elastic action of the elastic ring 6, then the liquid outlet 4 on the injector 1 is sleeved in the liquid inlet 5 on the micro pump connecting pipe 2, then one split part is placed beside the connecting part between the injector 1 and the micro pump connecting pipe 2, the elastic ring 6 is embedded in the arc groove 13 on the split part, simultaneously the arc plate 12 on the split part is attached to the side surface of the limiting ring 7 back to the injector 1, then the other split part is spliced on the former split part, and the latch 14 is embedded in the corresponding slot 15, thereby completing the installation of the reinforcing part 3.
