Abstract
The utility model discloses a novel positioning oil cylinder, which comprises a cylinder body, a piston, a piston rod, a guide sleeve, a front earring and a rear earring with a liquid through hole, wherein liquid through holes are formed in two ends of the cylinder body. The novel positioning oil cylinder is characterized in that a spring and a control piston are assembled between the piston and the rear earring; a jacking sleeve with a liquid through hole is arranged on the control piston; a taper is formed at the end part of the jacking sleeve; the jacking sleeve is inserted into an inner hole of the piston; a steel ball hole is formed in the inner hole wall of the piston; a steel ball is assembled in the steel bal hole; and a positioning groove is formed in the inner wall at the rear end of the cylinder body. The novel positioning oil cylinder disclosed by the utility model has the advantages that a closed cabin door or a sealing door can be accurately positioned and the reliability in sealing and convenience for use are realized.
Description
Technical field
The utility model belongs to a kind of fluid pressure drive device, particularly a kind of hydraulically powered novel location oil cylinder.
Background technique
Hatch door on submarine, aircraft, so the sealed door of some industrial facility employing hydraulic jack is controlled opening and closing, the seal when closing with assurance.But in the use of reality, have certain defective, as after closing, because the slow pressure release of hydraulic pressure, hatch door there is not positioning device, therefore can not remain air-tight state completely, makes troubles to use.
Summary of the invention
The purpose of the utility model provides a kind of novel location oil cylinder, and the hatch door or the sealed door of closing are accurately located, and is airtight reliable, easy to use.
The technological scheme that the utility model provides is following: it comprises the back earrings of cylinder body, piston, piston rod, guide sleeve, preceding earrings and the band liquid-through hole of two ends band liquid-through hole; It is characterized in that: assembling spring and control piston between piston and back earrings, the jack-up that the band liquid-through hole is set on the control piston is overlapped, and the end of jack-up cover is provided with tapering; The jack-up cover inserts the endoporus of piston; On the inner hole wall of piston, steel ball hole is set, the assembling steel ball has locating slot in the steel ball hole on the rear end of the cylinder block inwall.
The utility model has the advantages that: the hatch door or the sealed door of closing are accurately located, airtight reliable, easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the control piston package assembly enlarged diagram of the utility model.
Embodiment
See Fig. 1,2, the concrete structure of the utility model is following: cylinder body 13 two ends are provided with liquid-through hole 2,3 respectively, and cylinder body 13 front and back ends are fixedly connected the back earrings 4 of guide sleeve 14 and band liquid-through hole 1 respectively, earrings 15 before the front end of piston rod 12 connects.Assembling connects the piston 11 of piston rod 12 in cylinder body 13, and piston rod 12 ends are fixing with piston 11 through nut 10 and screw 8.Assembling spring 5 and control piston 6 between piston 11 and back earrings 4 are provided with the jack-up cover on the control piston 6, jack-up putting is provided with liquid-through hole, and this liquid-through hole can communicate with the liquid-through hole 2 on the cylinder body 13.The end of jack-up cover is provided with tapering, and the jack-up cover inserts the endoporus of piston 11 rear ends, on the inner hole wall of piston 11, steel ball hole is set, and assembling steel ball 9 has locating slot in the steel ball hole on cylinder body 13 rear end inwalls, and steel ball 9 can snap in locating slot and make piston 11 location.
Working principle: when hatch door or sealed door were opened, fluid got into from liquid-through hole 2, and liquid-through hole 1,3` pressure release; Oil pressure effect control piston 6 is compressed spring 5, and control piston 6 breaks away from piston 11; Steel ball 9 falls in the steel ball hole of piston 11, and piston 11 breaks away from the location, and oil pressure is pushed ahead piston 11; Be delivered to preceding earrings 15 through piston rod 12, realize opening state.
When hatch door or sealed door were closed, fluid got into from liquid-through hole 3, liquid-through hole 2 pressure releases, and piston 11 advances backward, and earrings 15 before being delivered to through piston rod 12 is realized closed condition.This moment, liquid-through hole 1 entering oil pressure withstood control piston 6, and the jack-up cover of control piston 6 inserts the endoporus of piston 11 rear ends; Its end tapering is with steel ball 9 jack-up of steel ball hole; Steel ball 9 blocks the location at the locating slot of cylinder body 13 inwalls, makes piston 11 location, and realization hatch door or sealed door are closed positioning states.
