Abstract
The utility model relates to a flexible oil cylinder which comprises a cylinder barrel, wherein the cylinder barrel is internally provided with an inner cylinder; the inner cylinder is internally provided with a plunger rod; the side walls of the cylinder barrel and the inner cylinder are provided with oil inlet holes; the side walls and the bottoms of the cylinder barrel and the inner cylinder are all provided with oil grooves; and seal rings are arranged between the plunger rod and the inner cylinder and between the cylinder barrel and the inner cylinder. The flexible oil cylinder provided by the utility model has the beneficial effects that because a sleeve joint structure is adopted, the oil cylinder is compact in structure, small in occupation space, low in manufacturing cost, long in flexible distance and rapid in flexible speed, and materials are saved, so that the stroke of the oil cylinder is lengthened, and the automation operation is more convenient.
Description
Technical field
The utility model relates to a kind of telescopic oil cylinder.
Background technique
Traditional telescopic oil cylinder is because oil cylinder is long, and difficulty of processing is big, often adds man-hour at piston rod; Can only utilize piston rod tube endoporus oily excessively, cause the bar tube to deposit a large amount of hydraulic oil, increase the weight of oil cylinder and the waste of hydraulic oil; Have a strong impact on the stationarity of telescopic oil cylinder, simultaneously the traditional direction ring is contained between primary seal and the cushion seal, can not solve the lubricity of sealing and causes the oil cylinder poor stability; And exist complex structure, and manufacture cost is big, and flexible distance weak point and stretching speed wait not enough slowly.
The model utility content
The purpose of the utility model provides a kind of telescopic oil cylinder, has remedied deficiency of the prior art.
The purpose of the utility model is to realize through following technological scheme:
A kind of telescopic oil cylinder comprises cylinder barrel, is provided with inner casing in the cylinder barrel; Be provided with plunger rod in the inner casing; Cylinder barrel and inner casing sidewall are equipped with oil inlet hole, and the sidewall and the bottom of cylinder barrel and inner casing are equipped with oil groove, are equipped with seal ring between said plunger rod and the inner casing and between cylinder barrel and the inner casing.
The beneficial effect of the utility model is: owing to adopt socket join structure, make the compact structure of oil cylinder, it is little to take up room, and saves material, low cost of manufacture, and flexible distance, stretching speed is fast, makes the stroke lengthening of oil cylinder, is convenient to automated job more.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described telescopic oil cylinder of the utility model embodiment.
Among the figure:
1, cylinder barrel; 2, inner casing; 3, plunger rod; 4, oil inlet hole; 5, oil groove; 6, seal ring.
Embodiment
As shown in Figure 1; The described a kind of telescopic oil cylinder of the utility model embodiment comprises cylinder barrel 1, is provided with inner casing 2 in the cylinder barrel 1; Be provided with plunger rod 3 in the inner casing 2; Cylinder barrel 1 is equipped with oil inlet hole 4 with inner casing 2 sidewalls, and the sidewall and the bottom of cylinder barrel 1 and inner casing 2 are equipped with oil groove 5, are equipped with seal ring 6 between said plunger rod 3 and the inner casing 2 and between cylinder barrel 1 and the inner casing 2.
The utility model in use; Hydraulic oil gets into oil groove 5 from the oil inlet hole 4 of cylinder barrel 1 and inner casing 2, and inner casing 2 receives the thrust of hydraulic oil with plunger rod 3 and stretches out, because the stroke of inner casing 2 oil grooves is longer; So the active force of the hydraulic oil of inner casing 2 little than in the cylinder barrel 1; Stretch out so the hydraulic oil in the cylinder barrel 1 promotes inner casing 2, treat that the hydraulic oil active force in the inner casing 2 increases, plunger rod 3 stretches out inner casing 2 under the effect of hydraulic oil.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technological scheme, all drops within the protection domain of the utility model.
