Abstract
The utility model discloses a kind of flanged butterfly springs, including butterfly spring ontology, the inner wall of the butterfly spring ontology is extended radially outward equipped with first annular flange, the outer wall of the butterfly spring ontology is radially inwardly extending to be equipped with the second annular flange, and the surface of the first annular flange and the second annular flange is equipped with gasket.It has the advantages of simple structure and easy realization, by effectively increasing the stroke of butterfly spring under the premise of not increasing spring number to the first annular flange of butterfly spring ontology setting and the second annular flange, reducing cost；In addition the setting of gasket can increase frictional force in two panels spring assembly, prevent the sliding of spring from existing, enhance stability.
Description
Technical field
The utility model is related to spring more particularly to a kind of flanged butterfly springs.
Background technology
Butterfly spring has the good characteristics such as small, energy storage is big, elasticity is good, is typically used as in national defence, metallurgy, work
The machinery industries such as journey, electric power, lathe, if if the maximum deformation quantity of existing butterfly spring is h, the maximum of that n piece combination
Deflection is nh, it is necessary to which designing a kind of can be effectively increased the butterfly spring of spring travel not increasing number of springs again.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of flanged butterfly spring, which passes through
The stroke of spring can be effectively increased after superposition.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of flanged butterfly spring, including butterfly spring ontology, the inner wall of the butterfly spring ontology radially to
Outer extend is equipped with first annular flange, and the outer wall of the butterfly spring ontology is radially inwardly extending to be equipped with the second annular flange,
The surface of the first annular flange and the second annular flange is equipped with gasket.
Preferably, the gasket is improved mat, the surface of the gasket is in rough shape.
Preferably, the outer surface of the butterfly spring ontology is equipped with protective layer.
Preferably, the width of the first annular flange and height are than being 4:1.
Preferably, the width of second annular flange and height are than being 4:1.
The utility model has the characteristics that following and advantageous effect：
It has the advantages of simple structure and easy realization, by the way that first annular flange and the second annular flange is arranged to butterfly spring ontology,
Under the premise of not increasing spring number, the stroke of butterfly spring is effectively increased, cost is reduced；In addition the setting of gasket,
In two panels spring assembly, frictional force can be increased, prevent the sliding of spring from existing, enhance stability.
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

Fig. 2 is the vertical view of the utility model.
Fig. 3 is the assembled state figure of the utility model.
The usage state diagram of Fig. 4 bitmaps 3.
In figure, 1- butterfly spring ontologies；The first annular flanges of 2-；The second annular flanges of 3-.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown, a kind of flanged butterfly spring, including butterfly spring ontology 1, the inner wall edge of butterfly spring ontology 1
It extends radially outwardly and is equipped with first annular flange 2, the outer wall of butterfly spring ontology 2 is radially inwardly extending to be equipped with the second convex annular
Edge 3, wherein butterfly spring ontology, first annular flange and the second annular flange can be selected welding or be integrally formed, and come relatively
It says that integrated molding is more secured, can be selected and be made of one piece in the utility model；First annular flange 2 and the second annular flange
3 surface is equipped with gasket 4.
Wherein, gasket is improved mat, and the surface of the gasket is in rough shape.
It is equipped with protective layer in the outer surface of further improvement of the utility model, butterfly spring ontology, protective layer can select
With silica type material, butterfly spring ontology can be effectively prevent to be scratched or broken by foreign object.
In the further improvement of the utility model, the width and height ratio of first annular flange and the second annular flange are
4:1, which can make first annular flange and the second annular flange more secured during the work time, extend product
Service life.
Operation principle：Such as Fig. 3, shown in 4, the butterfly spring that maximum deformation quantity when four work is h+h1 is combined one
It rises, when by outer force effect, the maximum deformation quantity of four butterfly springs is 4h+4h1, and maximum deformation quantity is when with originally working
The butterfly spring of h is compared effectively increases the spring travel of 4h1 under the premise of not increasing number of springs, reduce use at
This.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
