Abstract
The invention discloses a lift cylinder for multipurpose vehicles. The lift cylinder for the multipurpose vehicles is characterized in that one end of a cylinder barrel is welded with a cylinder bottom, a piston rod is sleeved in the cylinder barrel through a guide sleeve, a glyd ring and a support ring are mounted in an outer groove of a piston, a first O-ring and a first retainer ring are mounted in an inner groove of the piston, a locknut is arranged behind the piston, a dustproof ring, a piston rod seal ring, a support sleeve and a step seal are mounted in an inner groove of the guide sleeve, and a second O-ring and a second retainer ring are mounted in an outer groove of the guide sleeve. By the arrangement, the lift cylinder for the multipurpose vehicles is good in sealability and durability and is compact in structure and reliable in working performance for the multipurpose vehicles.
Description
Technical field
The present invention relates to a kind of for the hoist cylinder on the MPV (Multi-Purpose Vehicle).
Background technique
At present MPV (Multi-Purpose Vehicle) requires hoist cylinder must volume little, and compact structure to be to satisfy installation requirement, simultaneously because bearing the characteristics such as pressure height, poor working environment, requires it must possess good sealing and durable in use etc.
Summary of the invention
Purpose of the present invention is that a kind of compact structure is provided, the multifunctional vehicle hoist cylinder of reliable working performance.
To achieve these goals, the present invention is in cylinder barrel one end and cylinder bottom welding, the other end and guide sleeve screw by screw thread, piston rod is linked in the cylinder barrel by guide sleeve, the end that piston rod inserts in the cylinder barrel is provided with piston, in the piston outer channel Glais ring, support ring are installed, the one O type circle, the first back-up ring is installed in the piston internal channel, behind piston, be provided with locking nut, in the guide sleeve internal channel dust ring, rod seal circle, supporting sleeve, this special envelope are installed, in the guide sleeve outer channel the 2nd O type circle, the second back-up ring are installed.
By above setting, the present invention has possessed good sealing and property durable in use, for MPV (Multi-Purpose Vehicle) provides a kind of compact structure, and the multifunctional vehicle hoist cylinder of reliable working performance.
Description of drawings
Now the invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
Among the figure: 1, cylinder barrel, 2, cylinder bottom, 3, guide sleeve, 4, piston rod, 5, piston, 6, Glais ring, 7, support ring, the 8, the one O type circle, the 9, first back-up ring, 10, locking nut, 11, dust ring, 12, the rod seal circle, 13, supporting sleeve, 14, this special envelope, the 15, the 2nd O type circle, the 16, second back-up ring.
Embodiment
As shown in Figure 1, the present invention is in cylinder barrel 1 one ends and cylinder bottom 2 welding, the other end and guide sleeve 3 screw by screw thread, piston rod 4 is linked in the cylinder barrel 1 by guide sleeve 3, the end that piston rod 4 inserts in the cylinder barrel 1 is provided with piston 5, in piston 5 outer channel Glais ring 6, support ring 7 are installed, the one O type circle 8, the first back-up ring 9 is installed in piston 5 internal channel, behind piston 5, be provided with locking nut 10, in guide sleeve 3 internal channel dust ring 11, rod seal circle 12, supporting sleeve 13, this special envelope 14 are installed, in guide sleeve 3 outer channel the 2nd O type circle 15, the second back-up ring 16 are installed.
Working procedure of the present invention is as follows: during overhanging and retraction, support ring 7 provides side direction bearing capacity, impact-absorbing when piston rod 4; Glais ring 6 has low surface friction drag, and the high resistance extrusion capability plays main seal action, lets out in stoping between the large loculus of oil cylinder; The impurity such as dust of dust ring 11 outside the lip scraping piston rod 4 in the external world, 12 liang of lips of rod seal circle is tight clamping piston bar 4 under the pressure of high-pressure medium, plays main seal action; Supporting sleeve 13 support piston bars 4 prevent piston rod 4 scratches or off-centre; Si Te envelope 14 has the one-way sealing effect, is used in combination with rod seal circle 12, stops liquid to be revealed in guide sleeve 3 and piston rod 4 cooperation places, more than guarantees oil cylinder working seal reliability.
