Description
Technical Field
The utility model belongs to the technical field of the hydro-cylinder technique and specifically relates to a double containment hydro-cylinder uide bushing.
Background
The oil cylinder guide sleeve is used for sealing a front end cover of the oil cylinder, a sealing ring is arranged in the guide sleeve for tight sealing and oil leakage prevention, but the sealing ring is possibly damaged in the using process to cause oil leakage, so that the oil cylinder guide sleeve needs to be frequently replaced in the using process, and inconvenience is caused.
Disclosure of Invention
To the problem that exists among the prior art, the utility model provides a double containment hydro-cylinder uide bushing for sealed effect is more stable, reliable.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a double containment hydro-cylinder uide bushing, includes the uide bushing body, the center of uide bushing body is equipped with a through-hole, axial one side of uide bushing body is equipped with the flange face, be equipped with the sealing ring on the flange face, be equipped with dual sealing washer along circumference in the through-hole.
Adopt above-mentioned technical scheme, the setting of dual sealing washer can continue to provide sealedly at another layer sealing washer after one layer sealing washer is damaged, compares the individual layer sealing washer, and its sealed effect is better, and stand wear and tear degree is higher, and sealed more stable, reliable.
Furthermore, the inner edge of the sealing ring is provided with double sealing lips.
Adopt above-mentioned technical scheme, set up double seal lip and can make sealed effect better.
Furthermore, a sealing groove is formed in the through hole corresponding to the sealing ring, and the outer edge of the sealing ring is matched with the sealing groove.
By adopting the technical scheme, the sealing ring can be fixed on the inner wall of the through hole by matching with the sealing groove, so that the sealing ring is more firmly fixed.
Furthermore, the outer edge of the sealing ring is provided with a plurality of parallel raised annular rings, and the sealing groove is provided with corresponding grooves corresponding to the annular rings.
By adopting the technical scheme, the sealing ring and the sealing groove are firmer and are less prone to separation through the matching of the annular ring and the groove; and a plurality of annular teeth which are arranged in sequence are formed between the annular rings and are in a labyrinth seal structure to form a series of closure gaps and expansion cavities, and the sealed medium generates a throttling effect when passing through the gaps of the zigzag labyrinth to achieve the purpose of leakage resistance, so that the sealing effect of the sealing ring is better.
Further, the sealing ring is made of rubber materials.
By adopting the technical scheme, the rubber has good elasticity and strong contractibility, so that the sealing ring has stronger sealing capability.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an axial sectional view of the present invention.
Detailed Description
The following will further describe the embodiments of the present invention with reference to the drawings and examples.
As shown in fig. 1-2, the double-sealing oil cylinder guide sleeve comprises a guide sleeve body 1, wherein a through hole 11 is formed in the center of the guide sleeve body 1, a flange surface 12 is formed on one axial side of the guide sleeve body 1, a sealing ring 2 is arranged on the flange surface 12, and double sealing rings 3 are circumferentially arranged in the through hole 11. The setting of dual sealing washer 3 can continue to provide sealedly in another layer of sealing washer 3 after the damaged of one deck sealing washer 3, compares individual layer sealing washer 3, and its sealed effect is better, and stand wear and tear degree is higher, and sealed more stable, reliable.
The inner edge of the sealing ring 3 is provided with a double sealing lip 31. The sealing effect is better by providing the double sealing lip 31.
The through hole 11 is provided with a sealing groove 4 corresponding to the sealing ring 3, and the outer edge of the sealing ring 3 is matched with the sealing groove 4. The arrangement enables the sealing ring 3 to be fixed on the inner wall of the through hole 11 through matching with the sealing groove 4, so that the sealing ring 3 is fixed more firmly.
The outer fringe of sealing washer 3 is equipped with a plurality of parallel bellied rings 5, seal groove 4 corresponds rings 5 and is equipped with corresponding recess 6. In such an arrangement, the sealing ring 3 and the sealing groove 4 are firmer through the matching of the annular ring 5 and the groove 6, and the sealing ring 3 is less prone to being separated from each other; and a plurality of annular sealing teeth which are arranged in sequence are formed between the annular rings 5, a labyrinth sealing structure is formed, a series of closure gaps and expansion cavities are formed, and the sealed medium generates a throttling effect when passing through the gaps of the zigzag labyrinth to achieve the purpose of leakage resistance, so that the sealing effect of the sealing ring 3 is better.
The sealing ring 3 is made of rubber materials. The elasticity of the rubber is good, the contractibility is strong, and the sealing capability of the sealing ring 3 is stronger.
