Abstract
The invention discloses a dual-sealing device of an oil cylinder. The dual-sealing device comprises a cylinder cover and a sealing device, wherein the sealing device is arranged at the cylinder cover, and comprises a first sealing chamber, an oil storage tank and a second sealing chamber; and the oil storage tank is arranged between the first sealing chamber and the second sealing chamber. The oil storage tank is arranged between the two sealing chambers to reduce dry friction of second sealing, so that the loss of a product is reduced and the work schedule is increased; moreover, the dual-sealing device disclosed by the invention is simple in structure.
Description
Technical field
The present invention relates to a kind of seal arrangement, particularly relate to a kind of double-sealing device of oil cylinder.
Background technique
In the commercial production in modern times; Usually can use seal arrangement; The effect of seal arrangement prevents that the liquid of machine intimate or gas from letting out between the junction plane of two parts, the 2nd, prevent outside impurity, dust intrusion, and keep the necessary environment of mechanical parts proper functioning.
The double-sealing device of oil cylinder in the market, structure is more single, under long-time practical situation, can produce dry friction between the sealing of second road, influences job schedule easily, causes unnecessary trouble.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of double-sealing device of oil cylinder, can under situation about working long hours, also can not cause dry friction, has improved job schedule, and simple in structure.
For solving the problems of the technologies described above; The technological scheme that the present invention adopts is: the double-sealing device that a kind of oil cylinder is provided; Comprise: cylinder cap, seal arrangement; Described cylinder cap place is provided with seal arrangement, and described seal arrangement comprises between first road sealing, between oil storage tank, the sealing of second road, and described oil storage tank is arranged between the sealing of described first road and between between the sealing of described second road.
In preferred embodiment of the present invention, described oil storage tank bottom is provided with a plurality of holes.
The invention has the beneficial effects as follows: the double-sealing device of oil cylinder of the present invention; Comprise: cylinder cap, seal arrangement, described cylinder cap place is provided with seal arrangement, and described seal arrangement comprises between first road sealing, between oil storage tank, the sealing of second road; Described oil storage tank is arranged between the sealing of described first road and between between the sealing of described second road; Can under situation about working long hours, can not cause dry friction yet, improve job schedule, and simple in structure.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of the double-sealing device of oil cylinder of the present invention;
Fig. 2 be shown in the elevational schematic view of oil storage tank of double-sealing device of oil cylinder;
The mark of each parts is following in the accompanying drawing: 1, between first road sealing, and between the sealing of 2, second road, 3, oil storage tank, 4, cylinder cap, 5, hole, 6, seal arrangement.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.

The present invention discloses a kind of double-sealing device of oil cylinder; Comprise: cylinder cap 4, seal arrangement 6; Described cylinder cap 4 places are provided with seal arrangement 6; Described seal arrangement 6 comprises between first road sealing 1, between oil storage tank 3, the sealing of second road 2, described oil storage tank 3 be arranged between the sealing of described first road 1 and the sealing of described second road between between 2.
Preferably, described cylinder cap 4 places are provided with seal arrangement 6, and at cylinder cap 4 places one road sealing device 6 being set can increase the Seal of Equipment performance greatly.
Preferably; Described oil storage tank 3 be arranged between the sealing of described first road 1 and the sealing of described second road between between 2; Between first road sealing 1 and the sealing of described second road between add oil storage tank 3 together in the middle of 2, reduce between the sealing of second road by 2 dry friction, reduce the loss of product.
Preferably, described oil storage tank 3 bottoms are provided with a plurality of holes 5, and hole 5 is arranged at oil storage tank 3 bottoms, and oil can flow out from hole 5, and when oil cylinder was done the piston motion, oil can flow between the sealing of second road 2, prevents 2 dry friction between the sealing of second road.
The double-sealing device of oil cylinder of the present invention has solved the defective in the technological scheme, comprising: cylinder cap, seal arrangement; Described cylinder cap place is provided with seal arrangement; Described seal arrangement comprises between first road sealing, between oil storage tank, the sealing of second road, described oil storage tank is arranged between the sealing of described first road and between between the sealing of described second road, adds oil storage tank one in the middle of between two seals; Reduce the dry friction of second road sealing; Reduce the loss of product, improved job schedule, and simple in structure.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
