Abstract
The utility model relates to a hydraulic dustproof sealing ring, in particular to an airtight hydraulic dustproof sealing ring structure comprising an airtight dustproof sealing ring, a cylinder body and a piston rod, wherein one end of the inner side of the airtight dustproof sealing ring is provided with a dustproof lip part, the other end of the inner side of the airtight dustproof sealing ring is provided with an oil-proof lip part, a root part and an outer lip port, the dustproof lip part and the oil-proof lip part are both adhered to the surface of a piston rod body respectively and axially, the root part and the outer lip port are arranged in an installation groove of the cylinder body, and the root of the outer side of the airtight dustproof sealing ring is provided with an airtight dustproof lip port; the airtight dustproof lip port and the airtight dustproof sealing ring of the airtight dustproof sealing ring structure are made from the same material and form a whole; and in the airtight dustproof sealing ring structure, the dustproof lip part at the inner side and the airtight dustproof lip port at the outer side are respectively and elastically adhered to the outer surface of the piston rod body and the inner surface of the cylinder body. The utility model eliminates the possibility that dust and sand grains enter an oil cylinder from the piston rod and the dust seal installation position of the oil cylinder and the upper end of an installation casing of the oil cylinder in desert, a coal mine and a place with larger air pollution, and prolongs the service life of the sealing ring.
Description
Technical field:
The utility model relates to a kind of hydraulic pressure dust-proof seal ring, and particularly a kind of close gas-liquid is pressed the dust sealing coil structures.
Background technique:
Traditional hydraulic pressure dust sealing coil structures, all there is lip at inboard two ends, and an end of epipharynx is dustproof lip, and the other end is grease proofing lip, all can axially abut in the surface of the piston body of rod, and root places in the mounting groove of cylinder body.Because its root is embedded in the mounting groove of cylinder body, in the desert, colliery and the bigger place of atmospheric pollution, dust, the grains of sand and harmful gas in addition may be through piston rod and the installation places that is covered with dust, oil cylinder is installed the shell upper end and entered in the oil cylinder, cause the tightness early failue of hydraulic pressure dust sealing coil structures.
Summary of the invention:
The purpose of this utility model is to press the dust sealing coil structures for a kind of reliable, the long-acting novel close gas-liquid that the defective of the structure that overcomes existing hydraulic pressure dust-proof seal ring is invented with deficiency.
The utility model is realized by following technological means:
A kind of close gas dust sealing coil structures of the present utility model, by an end of its inboard is that dirt lip, the other end are that close gas dust-proof seal ring and cylinder body, the piston rod of grease proofing lip and root, outer lip formed, dirt lip, grease proofing lip all axially abut in the piston rod surface respectively, root, outer lip then place in the mounting groove of cylinder body, and described close gas dust-proof seal ring outside root is provided with the dustproof lip of close gas; Dustproof lip of the close gas of described close gas dust sealing coil structures and close gas dust-proof seal ring same material, and be one; The dustproof lip of the close gas of the inboard dirt lip of described close gas dust sealing coil structures and the outside flexibly abuts in the internal surface of piston rod external surface and cylinder body respectively.
The utility model compared with prior art has the following advantages:
In the desert, colliery, place that atmospheric pollution is bigger, eliminated dust, the grains of sand from oil cylinder piston bar and the installation place that is covered with dust, oil cylinder install the shell upper end enter in-oil cylinder may, prolonged working life of seal ring.
Description of drawings:
Fig. 1 is that close gas-liquid of the present utility model is pressed the dust-proof seal ring schematic cross-section.
Fig. 2 is that close gas-liquid of the present utility model is pressed dust-proof seal ring working state schematic cross-section.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further set forth.
According to Fig. 1, Fig. 2, a kind of close gas dust sealing coil structures of the present utility model, by an end of its inboard is that dirt lip 2, the other end are that close gas dust-proof seal ring 8 and cylinder body 6, the piston rod 7 of grease proofing lip 3 and root 5, outer lip 4 formed, dirt lip 2, grease proofing lip 3 all axially abut in piston rod 7 surfaces respectively, root 5,4 of outer lips place in the mounting groove of cylinder body 6, and close gas dust-proof seal ring 8 outside roots 5 are provided with the dustproof lip 1 of close gas; Dustproof lip 1 of the close gas of close gas dust sealing coil structures and close gas dust-proof seal ring 8 same material, and be one; The dustproof lip 1 of the inboard dirt lip 2 of close gas dust sealing coil structures and the close gas in the outside flexibly abuts in the internal surface of piston rod 7 external surfaces and cylinder body 6 respectively.
A kind of close gas dust sealing coil structures of the present utility model can play preventing that dust, gas etc. from entering in-oil cylinder possibility on piston rod 7, oil cylinder are installed shell.3 of grease proofing lips play knife-type oil stripping action on the piston rod 7 at the other end, have prevented that effectively close gas-liquid from pressing the tightness early failue of dust sealing coil structures, having prolonged working life of close gas dust-proof seal ring.
Although it is pointed out that here the utility model is described in detail, with regard to related domain staff, the similar modification of the class Sihe of making on this basis all should belong to the utility model protection domain.
Claims (3)
1. close gas dust sealing coil structures, by an end of its inboard is that dirt lip, the other end are that close gas dust-proof seal ring and cylinder body, the piston rod of grease proofing lip and root, outer lip assemblies, dirt lip, grease proofing lip all axially abut in the piston rod surface respectively, root, outer lip then place in the mounting groove of cylinder body, it is characterized in that: described close gas dust-proof seal ring outside root is provided with the dustproof lip of close gas.
2. a kind of close gas dust sealing coil structures according to claim 1 is characterized in that: dustproof lip of the close gas of described close gas dust sealing coil structures and close gas dust-proof seal ring same material, and be one.
