Abstract
The utility model discloses an oil cylinder of a forklift side shifter. The oil cylinder comprises a cylinder drum, wherein a piston is arranged in the cylinder drum. The oil cylinder is characterized in that a piston rod is respectively fixedly arranged on each of two sides of the piston, a cylinder head and a cylinder cover are respectively arranged at two ends of the cylinder drum, the piston rods penetrate through the cylinder head and the cylinder cover, and the contact surfaces of the piston rods and the cylinder head are sealed through U-shaped sealing parts. The oil cylinder is reasonable in structural design, is enhanced in performance and prolonged in service life, protects the U-shaped sealing parts, reduces cost, simultaneously is simple in processing technique and convenient to assemble and maintain, and meets use requirements.
Description
Technical field
The utility model relates to a kind of oil cylinder, relates in particular to a kind of fork lift side shifter oil cylinder.
Background technique
Fork lift side shifter is to realize that fork truck realizes the important tool of move left and right with the object of carrying, and the sidesway oil cylinder is the vitals of realizing move left and right, but sidesway oil cylinder cost is higher, the sidesway oil cylinder is small and exquisite and complicated, damage easily, working life is short, and installation, maintenance is complicated.
The model utility content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of fork lift side shifter oil cylinder to be provided, and its processing technology is simple, has reduced to become to produce cost, and the structural design by U-shaped Sealing has improved working life, assembling, easy to maintenance.
The utility model is achieved through the following technical solutions:
A kind of fork lift side shifter oil cylinder, include cylinder barrel, be provided with piston in the described cylinder barrel, it is characterized in that: the both sides of described piston are installed with respectively piston rod, the two ends of described cylinder barrel are separately installed with cylinder head and cylinder cap, described piston rod passes cylinder head and cylinder cap, and seals by U-shaped Sealing on the surface of contact of piston rod and cylinder head.
The outer end of described cylinder head is provided with step hole, and by U-shaped Sealing sealing, described U-shaped Sealing is U-shaped rubber pad between the surface of contact of described step hole and piston rod, and the outer side surface of U-shaped Sealing and cylinder cap applying.
The faying surface of described U-shaped Sealing and cylinder cap is provided with outside extension edge, and described cylinder cap interior edge face is pressed on extension edge and the cylinder head.
Its principle is: adopt U-shaped Sealing between piston rod and the cylinder head; strengthened sealing; improved working life; described U-shaped Sealing is installed in the cylinder head outer end, and fixes by cylinder cap, has protected U-shaped Sealing; reduced cost; processing technology is simple simultaneously, and usage requirement has been satisfied in assembling, easy to maintenance.
The utility model has the advantages that:
The utility model reasonable in design has strengthened sealing, has improved working life, has protected U-shaped Sealing, has reduced cost, and processing technology is simple simultaneously, and usage requirement has been satisfied in assembling, easy to maintenance.
