Description
Technical field
The utility model is related to a kind of buffer springs.
Background technology
Buffer spring is a kind of can to play that support, buffering, braking, height adjusts and the industry of the functions such as angular adjustment is matched
Part.It is made of following sections：Pressure cylinder, piston rod, piston, seal guide sleeve, filler（Inert gas or oil gas are mixed
Close object）, control element and cylinder outer control element and connector etc. in cylinder.Principle be filled in closed pressure cylinder inert gas or
Person's gas mixture makes several times or tens times of the pressure superatmospheric in cavity, small using the cross-sectional area of piston rod
The movement of piston rod is realized to the pressure difference generated in the cross-sectional area of piston.Buffer spring is widely used to various members
In the assembly of device, but existing buffer spring piston in use need to constantly rub with pressure cylinder, when buffer spring is used for
When suspention or the larger object of supported weight, especially press from both sides when existing between buffer spring axis and the object for being suspended or support
Larger frictional force is generated when angle, between piston and cylinder body, after long-time use, piston or cylinder body are probably damaged, shadow
Ring normal use.
Utility model content
The purpose of this utility model is to provide a kind of buffer spring, solve the piston or cylinder body in existing buffer spring
Flimsy problem.
What the technical solution of the utility model was realized in：
A kind of buffer spring includes tubular cylinder body, and the cylinder body axially directed is equipped with piston rod, the piston rod along its
One end stretch into cylinder interior, the other end of piston rod stretches out outside cylinder body, and piston rod is assembled with cylinder body sealing, the piston rod
Guide ring is equipped between cylinder body, one end that the piston rod stretches into cylinder body is fixedly connected with piston, is set on inboard wall of cylinder block
There are resistance to mill tube, the piston to be assembled with the sealing of resistance to mill tube, between piston and cylinder body, multigroup disc spring piece be installed on the piston,
The equal length of the length and inner chamber of cylinder block of the resistance to mill tube.
Further, the guide ring is made by rubber.
Further, the resistance to mill tube is non-metallic material.
Further, the guide ring is set on the piston rod.
Above-mentioned technical proposal is used, the beneficial effects of the utility model are：The buffer spring of the utility model by
Be set with nonmetallic resistance to mill tube on inboard wall of cylinder block, avoid metallic piston and metal cylinder body direct friction, to reduce cylinder body and
The possibility that piston is damaged by friction.Also, the resistance to mill tube in the utility model is fixed on cylinder by way of suit
On internal wall, after prolonged use, it is replaceable fall the resistance to mill tube ground away, enhance the service life of the utility model.Pass through
Rubber guide ring is set between piston rod and cylinder body, on the one hand enhances the steering capability between piston rod and cylinder body, it is another
Aspect enhances the sealing performance between piston rod and cylinder body.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the sectional view of the buffer spring of the utility model；
Wherein：1, cylinder body；2, resistance to mill tube；3, piston rod；4, guide ring；5, piston；6, disc spring piece.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
The specific embodiment of the buffer spring of the utility model, as shown in Figure 1, including cylinder body 1, cylinder body 1 is cylindrical tube shape
Structure, certainly, in other embodiments, the arbitrary shapes such as cylinder body 1 or rectangular cylinder.Cylinder body 1 is metal material, cylinder body 1
Along its it is axially directed be equipped with piston rod 3, piston rod 3 is cylindrical metal bar, and one end of piston rod 3 is stretched into cylinder body 1, and one end is stretched
Go out outside cylinder body 1, piston rod 3 is assembled with the sealing of tubular cylinder body 1.In order to keep piston rod 3 free to slide in cylinder, piston rod 3 with
Guide ring 4 is installed, the advantages of guide ring 4 in the present embodiment is made using rubber, is made using rubber between cylinder body 1
It is the sealing performance that can enhance piston rod 3 and cylinder body 1 on the basis of playing guide function.
One end that piston rod 3 stretches into cylinder body 1 is connected with piston 5, and the company of being welded and fixed is used between piston rod 3 and piston 5
It connects, piston rod 3 is cylindrical structure.In order to enhance the wear-resisting property between piston rod 3 and cylinder body 1, it is set on 1 inner wall of cylinder body
Resistance to mill tube 2, resistance to mill tube 2 are non-metallic material, and the diameter of the diameter and piston 5 of resistance to mill tube 2 is roughly equal, to realize resistance to mill tube
Assembly is sealed between 2 and piston 5.The equal length of the length and 1 inner cavity of cylinder body of resistance to mill tube 2 in the present embodiment, that is to say, that
Resistance to mill tube 2 covers the inner wall of cylinder body 1, it should be noted that the resistance to mill tube 2 in the present embodiment is the cylinder of both ends open.
Piston 5 in the present embodiment and multigroup disc spring piece 6 is installed between cylinder body, multigroup disc spring piece 6 using snapping side
Formula is placed.It connect, has on the outside of the cylinder body 1 of buffer spring and outer with external object for the ease of the buffer spring in the present embodiment
The U-bolt of boundary's object connection.
The buffer spring of the utility model is in use, occur relative friction, and resistance to mill tube 2 is between piston 5 and resistance to mill tube 2
Non-metallic material rubs, it is therefore prevented that cylinder body 1 or piston 5 are because of friction damage problem so as to avoid piston 5 and cylinder body 1.Also,
Resistance to mill tube 2 is fixed on by way of suit in cylinder body 1, when resistance to mill tube 2 is because of friction damage, can be replaced to it.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
