Abstract
The utility model provides a seawater-proof structure of a barge oil cylinder guiding sleeve. The seawater-proof structure of the barge oil cylinder guiding sleeve comprises a piston rod, the guiding sleeve, a dustproof ring, a waterproof ring and a sealing ring. The guiding sleeve is arranged on the piston rod in a sleeved mode, and annular grooves are formed in the joint between the guiding sleeve and the piston rod. The annular grooves include the first annular groove, the second annular groove and the third annular groove, wherein the first annular groove, the second annular groove and the third annular groove are sequentially arranged from outside to inside. The dustproof ring is arranged in the first annular groove, the waterproof ring is arranged in the second annular groove, and the sealing ring is arranged in the third annular groove. The seawater-proof structure of the barge oil cylinder guiding sleeve is simple in structure, good in waterproof effect and easy to manufacture and enables maintenance such as installation and replacement of a sealing part to be conveniently carried out.
Description
Technical field
The utility model relates to engineering oil cylinder field, refers to especially a kind of anti-seawater structure of barge oil cylinder guide sleeve of opening.
Background technique
The targeting part structure of general common engineering oil cylinder is all that earrings is twisted and is connected on piston rod by screw thread, and dust ring, U-shaped circle etc. are housed in guide sleeve successively; We know that this structure used in general environment, basically can satisfy condition, but use just not competent in the ocean environment of working condition very severe.
The model utility content
The utility model proposes the anti-seawater structure of a kind of barge oil cylinder guide sleeve, solved in the prior art and used with regard to inefficient problem in the ocean environment of working condition very severe.
The technical solution of the utility model is achieved in that a kind of anti-seawater structure of barge oil cylinder guide sleeve of opening, comprise: piston rod, guide sleeve, dust ring, waterproof ring, seal ring, described guide sleeve is sleeved on piston rod, have circular groove on the joint of described guide sleeve and piston rod, described circular groove comprises the first circular groove, the second circular groove, the 3rd circular groove, and described circular groove ecto-entad is the first circular groove, the second circular groove, the 3rd circular groove successively; Described dust ring is placed in the first ring shaped slot, and described waterproof ring is placed in the second circular groove, and described seal ring is placed in the 3rd circular groove.
Further comprise, described waterproof ring is U-shaped waterproof ring, and the opening of described waterproof ring is towards the direction of dust ring.
Further comprise, described seal ring is U-shaped seal ring, and the opening of described seal ring is towards the opposite towards the opening with waterproof ring.
Further comprise, the number of described seal ring is at least 1.
Beneficial effect: the utility model has solved the defect existed in the background technique, by the design of waterproof ring and at least one seal ring, has prevented the seepage of seawater.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation that Fig. 1 is an embodiment of the utility model.
Embodiment
As shown in Figure 1, a kind of anti-seawater structure of barge oil cylinder guide sleeve of opening, comprise: piston rod 1, guide sleeve 2, dust ring 3, waterproof ring 4, seal ring 5, guide sleeve 2 is sleeved on piston rod 1, have circular groove on the joint of guide sleeve 2 and piston rod 1, circular groove comprises the first circular groove 7, the second circular groove 8, the 3rd circular groove 9, and the circular groove ecto-entad is the first circular groove 7, the second circular groove 8, the 3rd circular groove 9 successively; Dust ring 3 is placed in the first circular groove 7; Waterproof ring 4 is placed in the second circular groove 8, and waterproof ring 4 is U-shaped waterproof rings, and the opening of waterproof ring 4 is towards the direction of dust ring 3.Seal ring 5 is placed in the 3rd circular groove, and seal ring 5 is U-shaped seal rings, and the opening of seal ring 5 is towards the opposite towards the opening with waterproof ring 4, and the number of seal ring 5 is at least 1, the utility model is preferred 2 layers of ring structure.
U-shaped waterproof ring 4 is contained in guide sleeve 2 circular grooves, and opening is towards the oil cylinder external direction; U-shaped seal ring fills 5 in guide sleeve 2 circular grooves, and opening, towards the oil cylinder internal direction, seals, and this spline structure forms the sealing configuration form of guide sleeve 2 anti-seawater seepages.Adopt the utility model structure, improve the reliability of pilot seal part, the inner machine hydraulic system fluid of protection oil cylinder Environmental Conditions.
The utility model is simple in structure, and good water-proof effect is easy to manufacture, and installation replacing Sealing etc. are easy to maintenance.Before improvement: general standard engineering oil cylinder working life in seawater is 2-3, overhaul 6-12 month/time.After improvement: reach 10-20 working life; Margin of safety improves several times; Overhaul 3-5/time.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
