Abstract
The utility model discloses a vertical oil cylinder. The vertical oil cylinder is characterized in that a base and one end of a cylinder barrel are welded together, a guide sleeve is connected with the other end of the cylinder barrel through a bolt, a piston rod is sleeved in the guide sleeve to be inserted into the cylinder barrel, a dustproof ring, a first support ring, a piston rod seal ring and an O-shaped ring are installed on the guide sleeve, a piston is installed on one end of the piston rod, which extends into the cylinder barrel, a combination ring and a second support ring are arranged on the piston, a locknut is arranged on the outer side of the piston, and a set screw fixes the locknut onto the piston rod. Through the arrangement, the vertical oil cylinder has good sealing performance, is compact in structure and satisfies the working requirements of the vertical oil cylinder.
Description
Technical field
The utility model relates to a kind of oil cylinder, is specifically related to a kind of for the Vertical Cylinders on the cement pump truck.
Background technique
Present cement pump car longevity of service, poor working environment, Vertical Cylinders is stressed large at work, requires it must have for a long time characteristics of withstand voltage, good seal performance.
Summary of the invention
The utility model is for the present real work situation of cement pump truck Vertical Cylinders, designed and developed out a kind of Vertical Cylinders of good seal performance, long working life.
The utility model is achieved through the following technical solutions:
Base and the welding of cylinder barrel one end, guide sleeve is connected with cylinder barrel the other end bolt, piston rod is linked in and inserts cylinder barrel in the guide sleeve, at guide sleeve dust ring, the first support ring, rod seal circle, O type circle are installed, stretch into an end of cylinder barrel at piston rod piston is installed, at piston combination envelope, the second support ring are installed, are provided with locking nut in the outside of piston, Cock screw will be fixed on locking nut on the piston rod.
By above setting, the utility model good seal performance, compact structure have reached the job requirement of Vertical Cylinders.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, base, 2, cylinder barrel, 3, guide sleeve, 4, piston rod, 5, dust ring, the 6, first support ring, 7, the rod seal circle, 8, O type circle, 9, piston, 10, the combination envelope, the 11, second support ring, 12, locking nut, 13, Cock screw.
Embodiment
As shown in Figure 1, base 1 of the present utility model and the welding of cylinder barrel 2 one ends, guide sleeve 3 is connected with cylinder barrel 2 the other end bolts, piston rod 4 is linked in and inserts cylinder barrel 2 in the guide sleeve 3, at guide sleeve 3 dust ring 5, the first support ring 6, rod seal circle 7, O type circle 8 are installed, stretch into an end of cylinder barrel 2 at piston rod 4 piston 9 is installed, at piston 9 combination envelope the 10, second support ring 11 is installed, be provided with locking nut 12 in the outside of piston 9, Cock screw 13 will be fixed on locking nut 12 on the piston rod 4.By above setting, during the utility model work, 10 the main seal actions of combination envelope on the piston 9, dust ring 5 on the guide sleeve 3 strikes off introduced contaminants, prevent from entering and damage sealing in the oil cylinder, Cock screw 13 and locking nut 12 just exist, and it is loosening that piston 9 is difficult for.
