Abstract
The utility model relates to a sealing device for a guiding sleeve. The sealing device comprises a piston rod and the guiding sleeve. A supporting ring and an O-shaped ring are embedded on the inner side surface of the guiding sleeve. A rectangular ring which is tightly connected with the O-shaped ring wraps the outer side face of the O-shaped ring. The outer side face of the supporting ring and the outer side face of the rectangular ring are attached with the outer wall of the piston rod. The sealing device has the advantages that the sealing combination is good in sealing performance, adhering tendency and climbing phenomena are avoided, the supporting ring can maintain the fact that metal surfaces between the piston rod and the guiding sleeve are separated, and accordingly the radial gap of an oil cylinder sealing system is enlarged, the supporting ring can also lower the mechanical friction between the piston rod and guiding sleeve, the performance of a sealing piece can be improved, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of seal arrangement for guide sleeve.
Background technique
General employing Y type sealing, the sealing of flower bud type etc. are selected in the sealing of common guide sleeve, after service time is long, can produce the problems such as sealability is not good, oil cylinder leakage, and the needs of Sealing are often changed, and working life is short.
The model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of seal arrangement for guide sleeve.
The utility model solves the technological scheme that its technical problem adopts: a kind of seal arrangement for guide sleeve, comprise piston rod and guide sleeve, the inner surface of guide sleeve is embedded with supporting ring and O type circle, O type circle outer side surface is coated with and the close-connected rectangular ring of O type circle, the outer side surface of supporting ring and rectangular ring and the laminating of the outer wall of piston rod.
Further, the quantity of supporting ring is two, and two supporting ring symmetries are positioned at the both sides of rectangular ring.
The beneficial effects of the utility model are: this seal combination has favorable sealing property, without adhesion propensity and creeping phenomenon; Supporting ring can keep separating of metal surface between piston rod and guide sleeve, thereby increases the radial clearance of cylinder seal system; Supporting ring also can reduce the mechanical friction between piston rod and guide sleeve, improves the performance of Sealing, increases the service life.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. piston rod, 2. guide sleeve, 3. supporting ring, 4.O type circle, 5. rectangular ring.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of seal arrangement for guide sleeve as shown in Figure 1, comprise piston rod 1 and guide sleeve 2, the inner surface of guide sleeve 2 is embedded with supporting ring 3 and O type circle 4, O type circle 4 outer side surfaces are coated with and the close-connected rectangular ring 5 of O type circle 4, the outer side surface of supporting ring 3 and rectangular ring 5 and the laminating of the outer wall of piston rod 1.
