Abstract
The utility model announces a kind of Novel hung oil cylinder protective equipment, belongs to oil hydraulic cylinder technical field.Comprise cylinder barrel and the piston rod stretching out cylinder barrel; On described cylinder barrel, cover has sleeve, between cylinder barrel and sleeve, be provided with support ring; Described piston rod earrings has a circle groove, groove is provided with clip; Described sleeve one end is fixed on piston rod earrings by described clip.The utility model dustproof effect is good, can ensure that piston rod is not collided with by foreign matters such as stones; There is good antiwear characteristic and impact resistance, and cost is lower; Sleeve and earrings mounting type, simple and convenient, easily change.
Description
Technical field
The utility model relates to oil hydraulic cylinder technical field, specifically a kind of Novel hung oil cylinder protective equipment.
Background technique
In use, piston rod stretches out cylinder barrel to oil hydraulic cylinder, and the dust at this moment in air and comparatively granule and piston rod collide, and pollutes piston rod, affects oil hydraulic cylinder precision and life-span.If run into larger foreign matter to collide with, directly may produce to piston rod the destruction that cannot repair.So, under the operating mode that Environmental Conditions is severe, oil hydraulic cylinder generally all can install protective equipment, particularly on suspension class oil hydraulic cylinder.Have in existing patent application number be 201310620150.8 dust guard for hydro-pneumatic suspension, it adopts the elastic rubber band tie rod being convenient to change, and this technology equally only can be applicable to prevent dust from entering and comparatively granule collision, and protection foreign matter collides with less effective.An application number is the oil cylinder dust-proof cover of 201220724001.7 in addition, it is made up of dust-proof cover and fixing device, flexible with cylinder movement, this Technical comparing is practical, but only can be applicable to prevent dust from entering and comparatively granule collision, protection larger foreign matter, particle are collided with less effective, and Placement poor stability, easily occur to loosen.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of Novel hung oil cylinder protective equipment.
The utility model is by the following technical programs: a kind of Novel hung oil cylinder protective equipment, comprises cylinder barrel and stretches out the piston rod of cylinder barrel; On described cylinder barrel, cover has sleeve, between cylinder barrel and sleeve, be provided with support ring; Described piston rod earrings has a circle groove, groove is provided with clip; Described sleeve one end is fixed on piston rod earrings by described clip.
It is further: described sleeve one end is bell mouth shape; Described clip internal surface is provided with a circle boss, and be a circle beveled in boss side, described boss snaps in the groove on piston rod earrings, and sleeve is that one end of bell mouth shape to be snapped in clip beveled and to be pressed on piston rod earrings by clip.
Described clip two ends are fastened by bolts, and are provided with around the spring on bolt between nuts and clip.
Have twice at the outer surface of cylinder barrel near piston rod earrings one end and support annular groove, described support ring is arranged on and supports in annular groove.
The present invention is fixed on sleeve one end on earrings by hoop component; the other end keeps relative sliding by twice support ring and cylinder barrel; then sleeve moves with earrings motion; make piston rod be in sleeve inner in host work process always, thus reach dust-proof and the effect of protection piston rod surface.
The utility model dustproof effect is good, can ensure that piston rod is not collided with by foreign matters such as stones; There is good antiwear characteristic and impact resistance, and cost is lower; Sleeve and earrings mounting type, simple and convenient, easily change.
