Abstract
A multi-layer hydraulic cylinder mechanism is composed of three convex ring E-shaped sealing rings, a concave ring slot on the external surface of piston and corresponding to the internal surface of E-shaped sealing ring, spiral steel wire rings in said ring slot, and the E-shaped sealing ring matched with said ring slot via the convex ring on internal surface of piston.
Description
Technical field
The utility model relates to a kind of hydraulic cylinder mechanism, and particularly a kind of multilayer hydraulic cylinder mechanism belongs to the hydraulic machinery technical field.
Background technique
At present, in hydraulic cylinder mechanism, between cylinder body and piston, all be provided with and install together or multiple-sealed circle; Thereby realize the effect of sealing, although existing seal ring shape is not quite similar,, all be resiliently deformable through seal ring self; Seal between realization piston and the cylinder body, As time goes on, seal ring can wear and tear gradually, thereby has reduced the effect of its sealing; Especially in hydraulic medium, exist under the situation of impurity, this wearing and tearing occur more easily, once this kind situation occurs, then will cause oil hydraulic cylinder to work normally; So existing oil hydraulic cylinder exists working life shorter, the defective of leaking easily.
The model utility content
The purpose of the utility model is: a kind of multilayer hydraulic cylinder mechanism is provided, and it is lower existing working life to overcome existing hydraulic cylinder mechanism, leak easily and brought thus can't proper functioning defective.
The utility model realizes that the technological method that above-mentioned purpose adopted is: a kind of multilayer hydraulic cylinder mechanism, the annulus E RunddichtringO of one or three roads protrusion is arranged, on the periphery of piston, have one with the corresponding matrix annular groove of inner headed face of E RunddichtringO; In piston matrix annular groove; Compartment of terrain suit spiral wire ring, the annulus of E RunddichtringO through protruding on its inner headed face agrees with in piston matrix annular groove; Piston rod is connected with piston, and piston and piston rod are installed in the endoporus of cylinder body.
The working principle of the utility model is: because the spiral wire ring has certain elasticity; So, in the elasticity of seal ring self, and under the elasticity acting in conjunction of spiral wire ring; Forcibly seal ring is pressed to cylinder wall; Wearing and tearing that on the one hand can the compensation sealing ring can prevent that impurity from causing wearing and tearing to other position further with the impurity retaining in the outside of this ring on the other hand.
Beneficial effect: a kind of multilayer hydraulic cylinder mechanism of the utility model, have sealing effect better, the advantage of long service life, be particularly useful in the high-pressure hydraulic; Effectively having overcome seal ring can wear and tear gradually, thereby has reduced the effect of its sealing, especially in hydraulic medium, exists under the situation of impurity; This wearing and tearing occur more easily; Once this kind situation occurs, then will cause oil hydraulic cylinder to work normally, so; Existing oil hydraulic cylinder exists working life shorter, the defective of leaking easily.
Description of drawings
Fig. 1 is the structure principle chart of the utility model;
Shown in the figure: 1, cylinder body; 2, E RunddichtringO; 3, piston; 4, spiral wire ring; 5, piston rod; 6, matrix annular groove.
Embodiment:
The annulus E RunddichtringO 2 that one or three roads protrusion is arranged; On the periphery of piston 3, have one with the corresponding matrix annular groove 6 of inner headed face of E RunddichtringO 2, in piston 3 matrix annular grooves 6, compartment of terrain suit spiral wire ring 4; The annulus of E RunddichtringO 2 through protruding on its inner headed face; Agree with in piston 3 matrix annular grooves 6, piston rod 5 is connected with piston 3, and piston 3 is installed in the endoporus of cylinder body 1 with piston rod 5.
