Abstract
The utility model discloses a combined oil cylinder which comprises an oil cylinder I and an oil cylinder II. The oil cylinder I and the oil cylinder II comprises piston rods, pistons, cylinder bodies, large cavities and small cavities respectively, and the large cavities and the small cavities are formed by the cylinder bodies and the pistons. The oil cylinder I and the oil cylinder II are mutually inverted and are integrally fixed. A large cavity oil inlet and a small cavity oil inlet which are connected with the large cavity and the small cavity of the oil cylinder I are arranged on the oil cylinder I. The combined oil cylinder further comprises a large cavity liquid conduit and a small cavity liquid conduit, the large cavity liquid conduit connects the large cavities of the oil cylinder I and the oil cylinder II, and the small cavity liquid conduit connects the small cavities of the oil cylinder I and the oil cylinder II. The two cylinders are combined in a mutual inverting mode so that the stroke of the combined oil cylinder is greatly increased on the condition of not changing the space occupation. In addition, the combined oil cylinder is simple to manufacture, convenient to maintain and low in cost, and can replace expansive multistage oil cylinders in many working conditions.
Description
Technical field
The utility model relates to a kind of oil cylinder, especially a kind of oil cylinder that has big stroke in the confined space.
Background technique
Oil cylinder is the straight line moving type executive component that the pressure reduction on ouput force and piston effective area and both sides thereof is directly proportional.Its function is can convert hydraulic pressure to mechanical energy.
Need oil cylinder to carry out under the operating mode of big stroke in the confined space, existing way is that multi-stage oil cylinder is set.But the multi-stage oil cylinder complex manufacturing technology, maintenance cost height, and rate of fault height.
The model utility content
At the technical problem of above-mentioned existence, the utility model provides a kind of combined type oil cylinder to utilize two oil cylinders to be inverted mutually and combines, and makes two piston rods flexible toward both direction respectively, has increased stroke.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of combined type oil cylinder comprises oil cylinder I and oil cylinder II, and described oil cylinder I and oil cylinder II comprise piston rod, piston, cylinder body, and the big chamber and the loculus that are formed by cylinder body and piston, and described oil cylinder I and oil cylinder II are inverted mutually, and are fixed together; Oil cylinder I is provided with big chamber filler opening and the loculus filler opening that communicates with big chamber and loculus respectively; Also comprise a big chamber fluid-through tube and a loculus fluid-through tube, described big chamber fluid-through tube is communicated with the big chamber of oil cylinder I and oil cylinder II, and described loculus fluid-through tube is communicated with the loculus of oil cylinder I and oil cylinder II.
As a kind of preferred, described oil cylinder I and oil cylinder II rely on connecting plate to fix.Be more prone to realize.
Usefulness of the present utility model is:
Combined type oil cylinder with said structure utilizes two oil cylinders to be inverted combination mutually, makes it under the constant situation that takes up room, stroke increases greatly, and it makes simple, easy to maintenance, with low cost, under a lot of operating modes, can substitute expensive multi-stage oil cylinder.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is rear view of the present utility model.
Mark among the figure: 1 oil cylinder I, 2 oil cylinder II, 3 piston rods, 4 cylinder bodies, 5 big chambeies, 6 loculuses, 7 big chamber filler openings, 8 loculus filler openings, 9 connecting plates, 10 big chamber fluid-through tubes, 11 loculus fluid-through tubes, 12 pistons.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The big chamber of oil cylinder loculus refers to that piston is divided into two-part with the cavity of cylinder interior, has one side of piston rod loculus, does not have one side of piston rod in big chamber.Toward big chamber oiling, piston rod stretches out outward; Toward the loculus oiling, piston rod is toward interior withdrawal.
Shown in Fig. 1-2:
The utility model comprises oil cylinder I1 and oil cylinder II2, described oil cylinder I1 and oil cylinder II2 comprise piston 12, piston rod 3, cylinder body 4, and the big chamber 5 and the loculus 6 that are formed by cylinder body 4 and piston 12, and described oil cylinder I1 and oil cylinder II2 are inverted mutually, and be fixed together, preferably utilize connecting plate 9 fixing; Oil cylinder I1 is provided with big chamber filler opening 7 and the loculus filler opening 8 that communicates with big chamber 5 and loculus 6 respectively; Also comprise a big chamber fluid-through tube 10 and a loculus fluid-through tube 11, described big chamber fluid-through tube 10 is communicated with the big chamber 5 of oil cylinder I1 and oil cylinder II2, and described loculus fluid-through tube 11 is communicated with the loculus 6 of oil cylinder I1 and oil cylinder II2.
In the time of use, by big chamber 5 oilings of big chamber filler opening 7 toward oil cylinder I1, because the big chamber 5 of oil cylinder I1 and oil cylinder II2 is by 10 connections of big chamber fluid-through tube, so the piston rod 3 of oil cylinder I1 and oil cylinder II2 all stretches out outward; By loculus filler opening 8 loculus 6 oilings toward oil cylinder I, because the loculus 6 of oil cylinder I1 and oil cylinder II2 is communicated with by the loculus fluid-through tube, so the piston rod 3 of oil cylinder I1 and oil cylinder II2 all back shrinks.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. combined type oil cylinder, comprise oil cylinder I and oil cylinder II, described oil cylinder I and oil cylinder II comprise piston rod, piston, cylinder body, and the big chamber and the loculus that are formed by cylinder body and piston, it is characterized in that: described oil cylinder I and oil cylinder II are inverted mutually, and are fixed together; Oil cylinder I is provided with big chamber filler opening and the loculus filler opening that communicates with big chamber and loculus respectively; Also comprise a big chamber fluid-through tube and a loculus fluid-through tube, described big chamber fluid-through tube is communicated with the big chamber of oil cylinder I and oil cylinder II, and described loculus fluid-through tube is communicated with the loculus of oil cylinder I and oil cylinder II.
