Abstract

The invention discloses a hydraulic oil cylinder with a novel connector body, belonging to the technical field of a hydraulic oil cylinder. The hydraulic oil cylinder comprises a cylinder bottom, a cylinder barrel, a piston, a piston rod, a guide sleeve and a connector body, wherein the piston rod is provided with two oil holes; the hydraulic oil cylinder further comprises an oil receiving sleeve sleeved on the connector body of the piston rod and through holes corresponding to oil openings of the two oil holes on the piston rod are arranged at the side wall of the oil receiving sleeve; and the oil receiving sleeve can move on the piston rod. The hydraulic oil cylinder with the novel connector body has the beneficial effects that the connector body is matched with the oil receiving sleeve so that the oil cylinder is more convenient to dismount and mount.

Description

A kind of hydraulic jack of novel fittings body
Technical field
The present invention relates to a kind of hydraulic jack of novel fittings body, belong to technical field of hydraulic oil cylinder.
Background technique
Oil hydraulic cylinder is the executive component that the pressure of oil hydraulic pump output can be converted into mechanical energy, and it mainly is to be used for linear movement output (also comprising oscillating motion), simple in structure, reliable operation.When realizing to-and-fro motion with it, can remove speed reducer from, and not have drive gap, therefore motion steadily is used widely in the hydraulic system of various machineries.Oil hydraulic cylinder is by its structural type, can be divided into three types of piston cylinder, plunger case and swing cylinders.Piston cylinder and plunger case are realized to-and-fro motion, thrust output and speed, and swing cylinder then can be realized the reciprocally swinging less than 360 degree, output torque and angular velocity.Oil hydraulic cylinder can also several combinations gets up or combines with other mechanism, to accomplish special effect except that single use.
Before and after being divided in the oil cylinder two oil pockets are arranged, one is that the bar oil pocket is arranged, and one is no bar oil pocket.The thrust that piston leans on hydraulic oil to inject the oil pocket generation is done the straight line back and forth movement between two oil pockets.Hydraulic cylinder is divided into two chambeies by piston, logical respectively oilhole, and when one of them oilhole oil-feed, piston will be pushed and make another oilhole fuel-displaced, and piston drive piston rod is done and is stretched out or retraction movement, and vice versa.But the oilhole place on the existing piston rod all is welded with connection block, causes the oil cylinder dismounting, trouble is installed.
Summary of the invention
To the problem that above-mentioned existing technology exists, the present invention provides a kind of hydraulic jack of novel fittings body, can make things convenient for the dismounting and the installation of oil cylinder.
To achieve these goals; The technological scheme that the present invention adopts is: a kind of hydraulic jack of novel fittings body; Comprise cylinder bottom, cylinder barrel, piston, piston rod, guide sleeve and fittings body; Offer two oilholes on the piston rod, also comprise be enclosed within connecing of piston rod upper connection body place have on the sidewall that oil jacket connects oil jacket two with piston rod on the corresponding through hole of oil port of two oilholes, connecing oil jacket can move on piston rod.
Connect the diameter that has through hole on the oil jacket diameter greater than the piston rod upper oil hole.
Connect oil jacket 7 and adopt Fine Steel Casting iron.
The invention has the beneficial effects as follows: hydraulic cylinder is divided into two chambeies by piston, the oilhole of offering on the logical respectively piston rod.During use; The oil outlet of hydraulic oil container and filler opening are aimed at two oilholes on the piston rod and are connected through connecing two through holes on the oil jacket respectively; When one of them oilhole oil-feed, piston will be pushed and make another oilhole fuel-displaced, and piston drive piston rod is done and stretched out or retraction movement; Vice versa, can guarantee the normal use of hydraulic jack.When not using or hydraulic jack when damaging, the removable oil jacket that connects is lifted down it from piston rod, and quick detachable when comparing oilhole place on the piston rod and being welded with connection block, employing fittings body as the same and the cooperation that connects oil jacket make the dismounting of oil cylinder more convenient during installation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, cylinder bottom, 2, cylinder barrel, 3, piston, 4, piston rod, 5, guide sleeve, 6, fittings body, 7, connect oil jacket.
Embodiment
To combine accompanying drawing that the present invention is described further below.
As shown in Figure 1; The present invention includes cylinder bottom 1, cylinder barrel 2, piston 3, piston rod 4, guide sleeve 5 and fittings body 6; Offer two oilholes on the piston rod 4; Also comprise be enclosed within piston rod 4 upper connection bodies 6 places connect oil jacket 7, connect have on the sidewall of oil jacket 7 two with piston rod 4 on the corresponding through hole of oil port of two oilholes, connecing oil jacket 7 can move on piston rod 4.
Hydraulic cylinder is divided into two chambeies by piston 3, the oilhole of offering on the logical respectively piston rod 4.During use; The oil outlet of hydraulic oil container and filler opening are aimed at two oilholes on the piston rod 4 and are connected through connecing two through holes on the oil jacket 7 respectively; When one of them oilhole oil-feed, piston 3 will be pushed and make another oilhole fuel-displaced, and piston 3 drive piston rods 4 are done and stretched out or retraction movement; Vice versa, can guarantee the normal use of hydraulic jack.When not using or hydraulic jack when damaging, the removable oil jacket 7 that connects is lifted down it from piston rod 4, and is quick detachable when comparing oilhole place on the piston rod 4 and being welded with connection block, as the same during installation.
Preferably, connect the diameter that has through hole on the oil jacket 7 diameter greater than piston rod 4 upper oil holes, guaranteeing that piston 3 can better be done stretches out or retraction movement.
Preferably, connect oil jacket 7 and adopt Fine Steel Casting iron, sealing effect is better, prevents that oil from leaking outside, and causes the waste of resource.
