Accompanying drawing explanation
Fig. 1 is the axial section of piston rod in the utility model,
Fig. 2 is the A place partial enlarged drawing of Fig. 1;
Fig. 3 be using state of the present utility model with reference to figure mono-,
Fig. 4 is that using state of the present utility model is with reference to figure bis-;
In figure, 1 is cylinder body, and 11 is upper piston chambeies, and 12 is lower piston chambeies, and 2 is intermediate plates, 20 is cushion plates, and 21 is vertical through holes, and 22 is magnet, and 23 is sluies, 230 is flowing holes, and 24 is end caps, and 241 is bodys, and 242 is port rings, 243 is stage clips, and 3 is piston rods, and 4 is upper pistons, 5 is lower pistons, and 6 is damper pistons, and 61 is driving rings, 62 is grafting rings, and 7 is limited rings, and 70 is inserting grooves.
Embodiment
The utility model as Figure 1-3, comprise cylinder body 1, intermediate plate 2, piston rod 3, upper piston 4, lower piston 5, damper piston 6 and limited ring 7, described cylinder body 1 is divided into upper piston chamber 11 and lower piston chamber 12 by intermediate plate 2, be arranged in the middle part of described piston rod 3 in intermediate plate 2, and with cylinder body 1 concentric, described upper piston 4 is slidably connected in upper piston chamber 11, and be fixedly linked with piston rod 3, described lower piston 5 is slidably connected in lower piston chamber 12, and be fixedly linked with piston rod 3, described limited ring 7 is fixedly connected on the top in lower piston chamber 12, described damper piston 6 is slidably connected between intermediate plate 2 and limited ring 7, and be socketed described piston rod 3,
The bottom surface of described intermediate plate 2 is also fixedly connected with the cushion plate 20 of ring-type;
The end face of described limited ring 7 offers the inserting groove 70 of ring-type;
