Abstract
The invention relates to the technical field of hydraulic devices, in particular to a hydraulic cylinder jacket comprising a jacket body, a scraping chamber, a filter chamber, an oil seal chamber and a cleaning chamber. The scraping chamber is formed in the front end of the jacket body. The filter chamber, the oil seal chamber and the cleaning chamber are sequentially formed behind the scraping chamber. The jacket is in the multilayer combined structure and used after a piston rod is sleeved with the jacket, so that a cylinder block is thoroughly and hermetically isolated from the outside, and dust and water and corrosion are prevented; normal operation of a cylinder is guaranteed effectively, and the service life of the cylinder is prolonged.
Description
Technical field
The present invention relates to hydraulic pressure installation technical field, especially a kind of hydraulic jack sheath.
Background technique
As a kind of conventional mechanical component, hydraulic jack is widely used at mechanical field, existing hydraulic jack is all provided with dust ring and is used for stopping extraneous dust, but in the long-term to-and-fro motion of piston rod, not only piston rod long term exposure outside, subject to damage, dust ring also can become flexible distortion, easily make dust, sewage enter cylinder body, affect performance, reduction of service life.
Summary of the invention
In order to overcome the deficiency of existing hydraulic jack easy damaged, dustproof and waterproof weak effect, the invention provides a kind of hydraulic jack sheath.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hydraulic jack sheath, comprise body, wiper Shi, filter chamber, oil sealing chamber and clean room, wiper chamber is placed in body front end, and filter chamber, oil sealing chamber and clean room are positioned at rear portion, wiper chamber and are arranged in order.
According to another embodiment of the invention, further comprise that wiper chamber is tapered, forwards outstanding.
According to another embodiment of the invention, further comprise and in filter chamber, be filled with nanometer Polyester Fibers.
According to another embodiment of the invention, further comprise the indoor sealing oil that is provided with of oil sealing.
According to another embodiment of the invention, further comprise and in clean room, be provided with asbestos ring.
The invention has the beneficial effects as follows, this sheath adopts multi-deck combined structure, be enclosed within on piston rod and use, wiper chamber can dash dust blowing, and the filtering of a step can be done to residuals by filter chamber, sealing, lubricated, antirust effect can be played in oil sealing chamber, clean room can be guaranteed the cleanliness that the inside and outside piston rod of cylinder body is consistent, thereby thoroughly cylinder body is isolated from the outside to sealing, waterproof and dustproof, corrosion protection, effectively ensure the normal operation of oil cylinder, extended working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. bodies in figure, 2. wiper Shi， 3. filter chambers, 4. oil sealing chamber, 5. clean room.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of hydraulic jack sheath, comprise body 1, wiper chamber 2, filter chamber 3, oil sealing chamber 4 and clean room 5, wiper chamber 2 is placed in body 1 front end, and filter chamber 3, oil sealing chamber 4 and clean room 5 are positioned at 2 rear portions, wiper chamber and are arranged in order.Wiper chamber 2 is tapered, forwards outstanding.In filter chamber 3, be filled with nanometer Polyester Fibers.In oil sealing chamber 4, be provided with sealing oil.In clean room 5, be provided with asbestos ring.
