Abstract
The utility model relates to a hydraulic cylinder, in particular to a lifting table hydraulic cylinder with vent valves, which is mainly used for solving the technical problems that internal pressure of lifting table hydraulic cylinders is high and easy to cause safety accidents and the like due to absence of vent valves in the prior art. The lifting table hydraulic cylinder with the vent valves comprises a cylinder body (1) and is characterized in that a lower end cap (2) and a cylinder cover (3) are respectively arranged at two ends of the cylinder body (1),a piston rod (4) is arranged inside the cylinder body (1), a piston (5) is arranged at an inner end of the piston rod (4), an outer end of the piston rod (4) extends outside the cylinder cover (3), and two vent valves (10) are respectively arranged at two ends of the piston (5) in the cylinder body (1).
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, especially relates to a kind of raising platform oil hydraulic cylinder with outlet valve.
Background technique
Raising platform is broad-spectrum high-lift operation special device.Its mechanical structure has higher steadiness after raising platform is hoisted, and roomy working platform and advantages of high bearing capacity make high-lift operation wider, and is fit to many people operations simultaneously.Existing raising platform can cause the oil hydraulic cylinder internal air pressure bigger with the outlet valve that do not have of oil cylinder, causes security incident easily.
The model utility content
The utility model provides a kind of raising platform oil hydraulic cylinder, and it mainly is to solve the do not have outlet valve of existing in prior technology raising platform with oil cylinder, can cause the oil hydraulic cylinder internal air pressure bigger, causes the technical problem of security incident etc. easily.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of raising platform oil hydraulic cylinder with outlet valve of the utility model comprises cylinder body, and the cylinder body two ends are respectively equipped with lower end cap and cylinder cap; Be provided with piston rod in the cylinder body; Piston rod the inner is provided with piston, and stretch out outside the cylinder cap piston rod outer end, all has an outlet valve on the cylinder body at piston two ends.
As preferably, have filler opening on the described lower end cap, have oil outlet on the cylinder body; Lower end cap is provided with the end earrings, and the piston rod outer end is connected with hanger.
Therefore, the utility model is provided with outlet valve on the cylinder body of oil cylinder, can reduce the air pressure in the oil hydraulic cylinder, avoids causing security incident, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: a kind of raising platform oil hydraulic cylinder with outlet valve of this example like Fig. 1, has a cylinder body 1; The cylinder body two ends are respectively equipped with lower end cap 2 and cylinder cap 3; Be provided with piston rod 4 in the cylinder body, piston rod the inner is provided with piston 5, all has an outlet valve 10 on the cylinder body at piston two ends.Stretch out outside the cylinder cap piston rod outer end, has filler opening 6 on the lower end cap, has oil outlet 7 on the cylinder body.Lower end cap is provided with end earrings 8, and piston rod 4 outer ends are connected with hanger 9.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
