Anti-shot ability.
Utility model content
For this purpose, the utility model provides a kind of lifting column cylinder that anti-shot ability is strong and the liter with the lifting column cylinder
Column drops.
To achieve the above object, the technical scheme that the utility model is provided is as follows:
A kind of lifting column cylinder, including the inner layer sleeve and outer layer sleeve being fixedly attached, the outer layer sleeve is stainless steel
The hardness of sleeve, the inner layer sleeve is greater than the outer layer sleeve, filled with sealing between the inner layer sleeve and outer layer sleeve
Layer.
Further, the surface that the inner layer sleeve exposes to outer layer sleeve is also coated with isolation paint layer.
Further, the sealant is sealed solid oil reservoir or sealant layer.
Further, the inner layer sleeve is No. 45 steel.
Further, it is fixedly attached between the inner layer sleeve and outer layer sleeve by being interference fitted realization.
Further, between the inner layer sleeve and outer layer sleeve by welding, be clamped or the realization that is spirally connected is fixedly attached.
Further, the outer peripheral surface of the inner layer sleeve upper end is equipped with a stage portion, the stage portion and the outer layer
Sleeve is enclosed annular link slot.
A kind of lifting column, including at least lifting column cylinder described above.
By technical solution provided by the utility model, have the following beneficial effects:
Lifting column cylinder is made of the inner layer sleeve and outer layer sleeve being fixedly attached, and outer layer sleeve is stainless steel sleeve, energy
Enough play anti-rust action, and stainless steel sleeve has certain intensity, extraneous scraping will not be damaged and cause to expose internal layer
Sleeve, protective value are good；The hardness of inner layer sleeve be greater than the outer layer sleeve, primarily serve resistance effect, and anti-shot ability compared with
The prior art is eager to excel；It is filled with sealant between the inner layer sleeve and outer layer sleeve, plays sealing effect, prevents extraneous steam
It permeates and oxidation corrosion inner layer sleeve；Whole anti-shot ability is strong, and service life can be ensured well.
Inner layer sleeve uses No. 45 steel, and No. 45 steel hardness are good, and price is cheap compared with stainless steel, and has on existing market ready-made
Meet the specification of present application, cost is lower.
Detailed description of the invention
Fig. 1 show the structural schematic diagram of lifting column cylinder in embodiment；
Fig. 2 show the decomposition diagram of lifting column cylinder in embodiment；
Fig. 3 show the cross-sectional view of lifting column cylinder in embodiment.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
Referring to figs. 1 to shown in Fig. 3, the present embodiment provides a kind of lifting column cylinders, including the inner layer sleeve 20 being fixedly attached
With outer layer sleeve 10, the outer layer sleeve 10 is stainless steel sleeve, and the hardness of the inner layer sleeve 20 is greater than the outer layer sleeve
10, sealant 30 is filled between the inner layer sleeve 20 and outer layer sleeve 10.Lifting column cylinder is by the internal layer set that is fixedly attached
Cylinder 20 and outer layer sleeve 10 form, and outer layer sleeve 10 is stainless steel sleeve, can play anti-rust action, and stainless steel sleeve has
Certain intensity, extraneous scraping will not be damaged and cause to expose inner layer sleeve 20, protective value is good；Inner layer sleeve 20 it is hard
Degree is greater than the outer layer sleeve, primarily serves resistance effect, and anti-shot ability is eager to excel compared with the prior art；20 He of inner layer sleeve
It is filled with sealant 30 between outer layer sleeve 10, plays sealing effect, prevents extraneous steam from permeating and oxidation corrosion inner layer sleeve
20；Whole anti-shot ability is strong, and service life can be ensured well.
Further, in the present embodiment, the inner layer sleeve 20 is No. 45 steel, and No. 45 steel hardness are good, and price is compared with stainless steel
Cheaply, and on existing market there is the ready-made specification for meeting present application, cost is lower.Of course, in other embodiments, it is interior
Prepared by layer sleeve 20 can also be carried out using other hardness existing material better than stainless steel, this is those skilled in the art
It can realize, no longer be described in detail easily.
Further, it in the present embodiment, is realized admittedly between the inner layer sleeve 20 and outer layer sleeve 10 by interference fit
Fixed socket；It is fixedly attached by the control of size to realize, because in the actual production process, inner layer sleeve 20 and outer layer sleeve 10
