Description
Technical field
The utility model relates to a kind of hydraulic device, in particular to a kind of hydraulic cylinder.
Background technique
Hydraulic cylinder includes cylinder barrel and piston rod assembly, and cylinder barrel includes the cartridge at middle part and the cylinder at cartridge both ends
Head, piston rod assembly include piston and piston rod, and piston is fixedly connected on the end of piston rod, the outer circumference surface and cylinder barrel of piston
Inner cavity is slidably matched, and in existing hydraulic cylinder, piston rod is usually connected through a screw thread with piston, i.e. the end of piston rod is set
Screw thread is set, piston centre sets inner hole, the screw thread being threadedly engaged with piston rod thread end is set on inner hole hole wall.Hydraulic cylinder it is reciprocal
In movement, piston and piston rod are main force-summing element, when work, piston front/rear end are acted on by hydraulic oil, with driving
Piston rod expanding-contracting action.When piston rod is withdrawn completely, due to effect of inertia, oil cylinder head can be still hit, entire oil cylinder is caused
Biggish impact.And under the action of shock and vibration and alternate stress, the threaded connection pair of piston and piston rod can generate pine
It is dynamic, it finally will lead to piston and loosened from piston rod.
Utility model content
The purpose of this utility model, which is that, provides a kind of novel design, hydraulic cylinder easy for installation, not easily to fall off, energy
It effectively solves the problems, such as above-mentioned.
To achieve the goals above, the technical solution adopted in the utility model is such that the hydraulic oil of the utility model
One end of cylinder body is arranged in cylinder, including cylinder body, gland, piston component and piston rod, gland, and piston component is arranged in cylinder body,
In piston rod one end, the piston rod other end stretches out gland for piston component setting, and the piston component includes left piston and right piston,
Left piston right side is provided with step-like groove, and the connecting rod of T shape is provided in groove, and through-hole is provided in right piston, right
Piston noose is in connecting rod, and left piston and right piston are connected through a screw thread, and connecting rod is fixedly connected with piston rod, the pressure
Oil duct is provided in lid, gland internal diameter is provided with oil pocket, and oil pocket two sides are respectively arranged with sealing ring, and oil pocket and oil duct one end connect
It connects, the oil duct other end is provided with oil nozzle.
Preferably, being provided with seal washer on the left piston.
Compared with the prior art, the advantages of the utility model are: the utility model is novel in design, piston component includes a left side
Piston and right piston, piston component is connect with piston rod by the connecting rod of T shape, is connected firmly, not easily to fall off, and installation side
Just, the oil pocket being provided between oil duct and gland and piston rod in gland communicates, and piston rod is avoided to block, and influences hydraulic cylinder
It works normally.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
Referring to Fig. 1, the hydraulic cylinder of the utility model, including cylinder body 1, gland 2, piston component and piston rod 4, gland 2
One end of cylinder body 1 is set, and piston component is arranged in cylinder body 1, and piston component is arranged in 4 one end of piston rod, and piston rod 4 is another
Gland 2 is stretched out at end, and the piston component includes left piston 31 and right piston 32, and 31 right side of left piston is provided with step-like recessed
Slot is provided with the connecting rod 41 of T shape in groove, is provided with through-hole in right piston 32,32 noose of right piston in connecting rod 41, and
Left piston 31 and right piston 32 are connected through a screw thread, and connecting rod 41 is fixedly connected with piston rod 4, are provided with oil in the gland 2
Road 6,2 internal diameter of gland are provided with oil pocket 8, and 8 two sides of oil pocket are respectively arranged with sealing ring, and oil pocket 8 is connect with 6 one end of oil duct, oil duct 6
The other end is provided with oil nozzle 7, is provided with seal washer 5 on the left piston 31.
The utility model is novel in design, and piston component includes left piston 31 and right piston 32, left piston 31 and right piston 32
It is connected through a screw thread, connecting rod 41 is set between left piston 31 and right piston 32 and is connect with piston rod 4, piston component and piston are made
It is not easy to loosen between bar 4, be connected firmly, it is not easily to fall off and easy for installation, oil duct 6 and gland 2 and piston are provided in gland 2
Oil pocket 8 between bar 4 communicates, and oil nozzle 7 is arranged on oil duct 6, carries out fuel feeding to oil pocket 8 by oil nozzle 7, piston rod 4 is avoided to block,
Influence the normal work of hydraulic cylinder.
