Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and can not limit protection model of the present utility model with this
Enclose.
A kind of small-sized threaded body one-way cylinder, as shown in Figures 2 and 3, including cylinder body 1, piston rod 2, oil cylinder cover 3, pressure
Contracting spring 6, filter 11, pressing plate and ferrule fitting 15, the outer lower portion of cylinder body 1 are designed for external screw thread, and filter 11 is located at
The side of cylinder body 1, piston rod 2 are located at cylinder body inner hub location, and piston rod 2 is connected with pressing plate, and oil cylinder cover 3 is located at oil cylinder
The bottom of body 1, ferrule fitting 15 are located at the lower section of cylinder body 1, and ferrule fitting 15 is connected with oil cylinder cover 3, and pressing plate can be by piston rod 2
Drive and freely activity, compression spring 6 is enclosed on the outside of piston rod 2.
O-ring back-up ring 7 is located at the periphery of piston rod 2, does anti-extrusion ring use.Second connecting pin 10 is located at the top of piston rod 2
End.Dust ring 5 is located between piston rod 2 and cylinder body 1.Stripped nut 13 is located at the outside of cylinder body 1.Pressing plate passes through hinge
