Abstract
The utility model discloses a hydraulic cylinder, which comprises a cylinder body, an oil tank, a piston, a piston rod and a sealing structure. The piston is arranged inside the cylinder body; both sides of the piston respectively form an oil chamber; the oil tank is respectively communicated with the oil chambers through oil paths; the piston rod is fixedly arranged on the piston and runs through the piston and the cylinder; both ends of the piston rod are exposed out of the cylinder body; and the piston rod is the hollow structure. The hydraulic cylinder is characterized in that when moving, the piston rod can serve as a moving delivery pipe connected with compressed air, liquid and the like, so that the piston rod serves as a liquid or air delivery pipe; the hydraulic cylinder has more functions, so as to meet the need for a moving conduit in industrial production effectively; in addition, the hydraulic cylinder has simpler structure and more convenient control; moreover, various wires and pipelines can run through the cylinder during installation, so as to bring convenience to the installation.
Description
Technical field
The utility model relates to a kind of hydraulic pressure installation, especially a kind of hydraulic jack.
Background technique
Hydraulic jack is more and more wider in industrial application at present, and it is simple to operate, and control is convenient, can effectively provide power, good stability, and that uses aspect Stroke Control is particularly extensive.But present hydraulic cylinder piston rod is a solid construction, inner oil pocket has been full of oil again, thereby make external object can't pass oil cylinder etc., as various electric wires, pipeline can't pass oil cylinder when installing, and the effect of oil cylinder also only limits to power plant, can not become gas circuit or pipeline, this has brought inconvenience for the installation of hydraulic jack, use.
Summary of the invention
The purpose of this utility model is the hydraulic jack of a kind of piston rod hollow of providing for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the hydraulic jack that the utility model is designed, it mainly comprises cylinder body, fuel tank, piston, piston rod and sealing configuration, the piston setting is wanted in the cylinder body, and the piston both sides respectively form an oil pocket, and fuel tank is communicated with respectively with oil pocket by oil circuit, piston rod is fixedly installed on the piston, described piston rod runs through piston and cylinder body, and the two ends of piston rod all are exposed at the cylinder body outside, and this piston rod is a hollow structure.Sealing configuration seals the cylinder body two ends, prevents leakage of oil.Oil in the fuel tank moves back and forth by the oil circuit driven plunger and is this field routine techniques, does not add tired stating at this.
Preferred scheme is that described piston rod one end is connected with hollow pull rod, the surface both sealing, and hollow structure is connected, so that in transmission, can keep the unimpeded of hollow structure structure again.
In order to make pressurized air effectively by oil cylinder, the described piston rod the other end can connect the pressure air source.
The resulting hydraulic jack of the utility model, piston rod is in motion, the conveyance conduit that also can become a motion is connected with pressurized air, liquid etc., make piston rod become indusion tube and pneumatic tube, the function of hydraulic jack is more, can effectively satisfy in the industrial production needs thus, and structure is more simple, controls more convenient to the conduit of motion; On the other hand, various electric wires, pipeline also can pass oil cylinder during installation, bring convenience to installation.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation;
Fig. 2 is the utility model embodiment 2 a structural representation.
Among the figure: cylinder body 1, fuel tank 2, piston 3, piston rod 4, oil pocket 5, hollow pull rod 6, pressure air source 7, sealing configuration 8.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the described hydraulic jack of present embodiment, it mainly comprises cylinder body 1, fuel tank 2, piston 3, piston rod 4 and sealing configuration 8, piston 3 is provided with to be wanted in the cylinder body 1, and piston 3 both sides respectively form an oil pocket 5, and fuel tank 2 is communicated with respectively with oil pocket 5 by oil circuit, piston rod 4 is fixedly installed on the piston 3, described piston rod 4 runs through piston 3 and cylinder body 1, and the two ends of piston rod 4 all are exposed at cylinder body 1 outside, and this piston rod 4 is a hollow structure.Sealing configuration seals cylinder body 1 two ends, prevents leakage of oil.
When mounted, various electric wires, pipeline also can pass oil cylinder, bring convenience to installation.
As shown in Figure 2, the described hydraulic jack of present embodiment, piston rod 4 one ends of the above are connected with hollow pull rod 6 on embodiment 1 basis, the surface both sealing, hollow structure is connected, and piston rod 4 the other ends can connect presses air source 7.So that in transmission, can provide one to press the air road to use again for producing to go up.
This hydraulic jack is used for machine tool, and hollow pull rod 6 is in transmission connection with claw on the chuck, and swinging back and forth by hollow pull rod 6 drives that claw is opened, closure, after machining, presses air Lu Ketong pressurized air, in order to discharging.
