Abstract
The invention discloses a single-action telescopic sleeve hydraulic cylinder sealing protective device. The device is characterized in that: a multi-layer multi-stage cylinder is arranged inside a coating cylinder; one end among the multi-layer multi-stage cylinder is respectively provided with a guiding component, a spacing component, a main seal ring, an auxiliary seal ring and a dustproof ring; two guide rings are arranged between the main seal ring and the auxiliary seal ring; and two guide rings are arranged between the auxiliary seal ring and the dustproof ring. By means of the arrangement, the seal ring in the seal component is prevented from being deformed and torn, and the oil cylinder is prevented from leaking oil or falling off and the like when being lifted.
Description
Technical field
The present invention relates to a kind of sealing protective device of hydraulic jack, is a kind of sealing protective device of single-action telescopic sleeve hydraulic cylinder specifically.
Background technique
Dumping car is with in the front-located mode sleeve hydraulic cylinder sealing component at present, and seal ring basically all belongs to open architecture.The dumping car user is when drawing viscous material; Unloading for ease; In loading space lifting process, " carry car suddenly " forward or " fierce braking ", cylinder barrels at different levels bear great lateral force, cause seal ring distortion in the sealing component, tear; Lose due sealing effect, cause and phenomenon such as do not fall after oil cylinder leakage of oil or the lifting after rise.
Summary of the invention
The object of the invention is the sealing protective device that a kind of safe and reliable single-action telescopic sleeve hydraulic cylinder is provided.
For realizing above-mentioned purpose; The inside of its external sleeve cylinder body of the present invention is provided with the multistage cylinder body of multilayer; End between the multistage cylinder body of multilayer is respectively equipped with guide member, spacing member; Primary seal circle, secondary seal ring, dust ring are provided with the twice guide ring between primary seal circle and secondary seal ring, between secondary seal ring and dust ring, be provided with the twice guide ring.
Through above setting, the present invention is installed between dump Truck Frame and the loading space, cylinder bodies at different levels bear great lateral force during unloading, and the seal ring in the sealing component can not be out of shape to be torn, and can not cause phenomenon such as not fall after oil cylinder leakage of oil or the lifting after rise.
Description of drawings
Combine accompanying drawing that the present invention is further specified at present.
Fig. 1 is an overall structure schematic representation of the present invention.
Among the figure: 1, overcoat cylinder body, 2, multistage cylinder body, 3, guide member, 4,
Spacing member, 5, the primary seal circle, 6, secondary seal ring, 7, dust ring.
Embodiment
As shown in Figure 1; The inside of its external sleeve cylinder body 1 of the present invention is provided with the multistage cylinder body 2 of multilayer; End between the multistage cylinder body 2 of multilayer is respectively equipped with guide member 3, spacing member 4; Primary seal circle 5, secondary seal ring 6, dust ring 7 are provided with the twice guide ring between primary seal circle 5 and secondary seal ring 6, between secondary seal ring and dust ring, be provided with the twice guide ring.Through above setting, before the present invention is arranged in primary seal circle 5 with guide member 3, reach between secondary seal ring 5 and the dust ring 6 between primary seal circle 5 and the secondary seal ring 6, the primary seal circle 5 in the sealing component, secondary seal ring 6 have been played the safety protection effect.
