Abstract

A kind of hydraulic oil container oil return filter cylinder, including flange cylinder, filter core, the flange cylinder include upper flange, lower flange, wherein upper flange has been connected with cover plate, the cover plate has the spring base for stretching into flange tube inner chamber, and one end of spring base support spring, the other end of spring withstands on the upper end of sleeve pipe;The flange cylinder lower end edge filter core installation direction is connected with many pull bars, and the base plate of the pull bar bottom welding is the hollow structure with counterbore so that flange cylinder, pull bar, base plate connect into cartridge assembly;The lower end of filter core is connected with the counterbore, and the radial direction for being used to limit filter core jumps;The upper end of filter core is connected with the bottom of sleeve pipe.Its advantage is simple structure, and the assembling and dismounting of filter cylinder, filter core are safeguarded and changes easy, efficient;It is lightweight, assembling more facilitate, user change filter core it is also more convenient, hydraulic oil oil return oil strain mode from inside to outside, good reliability.

Description

Hydraulic oil container oil return filter cylinder
Technical field
The utility model is related to the mounting structure of installation oil return filter core in construction machinery hydraulic oil tank.It is more particularly to a kind of The hydraulic oil container used on hydraulic oil container on automobile or engineering truck oil return filter cylinder.
Background technology
Oil return filter core is the critical elements of construction machinery hydraulic system composition, and the cleannes to hydraulic system oil liquid are provided Important leverage, traditional oil return filter element assembly mounting structure is complicated, and bothersome laborious in assembling, to the manufacturing, assembling And later maintenance brings invisible cost.The present invention provides a kind of simple and direct reliable oil return filter core mounting structure, Ke Yi It is convenient in manufacture to realize, because structure and weight are greatly simplified, also easily realized in fit on, also may be used in later maintenance use To be convenient for changing filter core.
Utility model content
The purpose of this utility model is just to provide a kind of light-duty easily hydraulic oil container oil return filter cylinder.
Solution of the present utility model is such:
A kind of hydraulic oil container oil return filter cylinder, including flange cylinder, filter core, the flange cylinder include upper flange, lower flange, its Middle upper flange has been connected with cover plate, and the cover plate has the spring base for stretching into flange tube inner chamber, the one of spring base support spring End, the other end of spring withstands on the upper end of sleeve pipe;The flange cylinder lower end edge filter core installation direction is connected with many pull bars, described The base plate of pull bar bottom welding is the hollow structure with counterbore so that flange cylinder, pull bar, base plate connect into cartridge assembly;Filter The lower end of core is connected with the counterbore, and the radial direction for being used to limit filter core jumps;The upper end of filter core is connected with the bottom of sleeve pipe.
More specifically technical scheme also includes:Described sleeve pipe is pipe dish welded type sub-assembly, and weld seam is arranged on top.
The utility model has the advantages that simple structure, the assembling and dismounting of filter cylinder, filter core maintenance is changed easy, efficient;;Weight Amount is light, and assembling more facilitates, and it is also more convenient that user changes filter core, hydraulic oil oil return oil strain mode from inside to outside, good reliability.

Reference is in figure:Cover plate 1, bolt 2, packing ring 3, O-ring 4, flange cylinder 5, spring 6, bolt 7, sleeve pipe 8, filter Core 9, pull bar 10, base plate 11, the first O-ring 12.
Specific embodiment
As shown in figure 1, the present invention includes flange cylinder 5, filter core 9, the flange cylinder 5 includes upper flange, lower flange, wherein on Flange has been connected with cover plate 1, and the cover plate 1 has the spring base for stretching into flange tube inner chamber, the one of spring base support spring 6 End, the other end of spring 6 withstands on the upper end of sleeve pipe 8.The structure of cover plate 1 is as shown in Figure 5.
As shown in Figure 2,3, the lower end edge filter core installation direction of the flange cylinder 5 is connected with many pull bars 10, the pull bar bottom The base plate 11 of portion's welding is the hollow structure with counterbore so that flange cylinder 5, pull bar 10, base plate 11 connect into cartridge assembly;Filter The lower end of core 9 is connected with the counterbore, for fixing filter core bottom cylindrical, filter core is not produced after being fixed and radially jumps;Filter The upper end of core is connected with the bottom of sleeve pipe 8.
As shown in figure 4, sleeve pipe 8 is pipe dish welded type sub-assembly, weld seam is arranged on top, in order to avoid can make filter core pressure in bottom It is not tight, it is to avoid oil return is returned directly to tank bottoms without oil return filter.
