Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a ration filling ware for environmental monitoring sampling, including cylinder 1, piston 12 has been placed to 1 inboard bottom of cylinder, piston 12 top fixedly connected with connecting rod 5, 1 inboard top of cylinder is equipped with the internal thread, spliced pole 2 has been placed at 1 inboard top of cylinder, spliced pole 2 outside bottom is equipped with the external screw thread, spliced pole 2's external screw thread and cylinder 1's internal thread looks adaptation, spliced pole 2 top middle part is opened has through hole 9, through hole 9 runs through spliced pole 2, connecting rod 5 passes through hole 9 and extends to spliced pole 2's one end fixedly connected with briquetting 6, extrude connecting rod 5 through briquetting 6, make piston 12 remove in cylinder 1, install lock mechanism between spliced pole 2 and the connecting rod 5, 1 bottom fixedly connected with toper section of thick bamboo 8 of cylinder, toper section of thick bamboo 8 helps drawing reagent from the.
The buckling mechanism comprises two positioning holes 3, the two positioning holes 3 are located at the top end of the connecting column 2, the two positioning holes 3 are symmetrical relative to the axis of the connecting rod 5, a sliding groove 7 is formed in the side face of the connecting rod 5 relative to the positioning holes 3, a sliding block 11 is placed in the sliding groove 7, one end of the sliding block 11, far away from the sliding groove 7, of the buckling ring 4 is fixedly connected with a buckling ring 4, a clamping block 10 is fixedly connected with the bottom end of the buckling ring 4, the clamping block 10 is matched with the positioning holes 3, a limiting block 15 is fixedly connected with the top of the outer side of the connecting rod 5, the limiting block 15 is located above the.
An annular groove 13 is formed in the side face of the piston, a sealing ring 14 is placed in the annular groove 13, one side, far away from the piston 12, of the sealing ring 14 abuts against the inner side wall of the needle cylinder 1, and the sealing ring 14 can prevent a reagent in the quantitative filling device from flowing from one side to the other side of the piston 12.
