Abstract
The utility model relates to a pressure spring with alternative large rings and small rings, comprising a spring body formed by spiral rings. The large-small ring alternate pressure spring is characterized in that the spring body is formed by arranging more than three large rings and more than three small rings alternatively, wherein the outside diameter of each small ring is less than the inside diameter of each large ring. Because the spring is formed by arranging the large rings and the small rings alternatively, and the outside diameter of each small ring is less than the inside diameter of each large ring, when the spring is compressed, the large rings are positioned outside the small rings and when the spring is compressed to the limit, all the large rings are mutually attached and all the small rings are mutually attached to the inner sides of all the large rings so that the compression distance of the spring is large.
Description
Technical field
The utility model relates to a kind of spring, especially relates to a kind of pressure spring.
Background technique
Spring is a kind of common part in the structural establishment of industrial or agricultural and daily life.Existing pressure spring generally all adopts the cylindrical helical structure, is made of measure-alike spiral bullet circle.But a remarkable defective of this pressure spring is that its reduction length is limited, has influenced the design size of machinery to a great extent.In order to improve the reduction length of pressure spring, promptly obtain longer length of spring compressed distance with shorter spring length, people have designed some successful spring structures.As publication number is that the Chinese patent of CN101598183 discloses a kind of spring, comprise: the first spring outer ring, the second spring outer ring and the spring inner ring that form with a steel wire coiling, described first spring outer ring and the described second spring outer ring are distributed in spring inner ring both sides, and the bore of the described spring inner ring of relative aperture of described first spring outer ring and the described second spring outer ring is big.The spring of this shape has damping, buffering and on-deformable characteristics.The spring of this shape is equivalent to reduce the stroke space greatly with two combinations that the pagoda spring microcephaly is relative, than adopting two combinations that the pagoda spring microcephaly is relative, reduces material, saves cost.And the spring of this shape has damping and on-deformable characteristics.But because this scheme only relates to two spring outer rings and a spring inner ring, its reduction length is still very limited, and this scheme all is a kind of structure of great circle owing to only having adopted two ends simultaneously, so it is difficult to install on the less mechanism structure of fitting limit.
Summary of the invention
The utility model mainly is that the compression distance of solution existing in prior technology pressure spring is shorter, influence the space of mechanical structure, and existing improvement project has compression distance and increases the technical problem limited, that inconvenience etc. is installed, and provides a kind of compression distance long, easy for installation, constitutionally stable pressure spring.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of big ringlet alternative pressure spring, comprise the spring body that constitutes by spirality bullet circle, it is characterized in that spring body alternately is made of big bullet circle, submissile circle, large and small bullet circle is more than 3, and wherein the external diameter of submissile circle is less than the internal diameter of big bullet circle.This spring alternately is made of big submissile circle, and the external diameter of submissile circle is less than the internal diameter of big bullet circle, so when spring stress compresses, big bullet circle is in the outside of submissile circle, when it is compressed to the limit, each big bullet circle fits, and each submissile circle makes that in the inboard applying mutually of big bullet circle the compression distance of this spring is very big.Again since the employing of this spring the structure that replaces of big submissile circle, so the stability under loading of its side direction still can be near common cylindrical spring, influenced hardly.
As preferably, a kind of big ringlet alternative pressure spring according to claim 1 is characterized in that the upper/lower terminal of described spring body is big bullet circle, and big bullet circle is 4-7, and the submissile circle is 3-6, and big bullet circle is Duoed one than the submissile circle.The big bullet circle at two ends can be used to support force structure, and it is more firm to make that it can be installed.
As preferably, a kind of big ringlet alternative pressure spring according to claim 1 is characterized in that the upper/lower terminal of described spring body is the submissile circle, and the submissile circle is 4-7, and big bullet circle is 3-6, and the submissile circle is Duoed one than big bullet circle.The submissile circle at two ends can be used to support force structure, makes it can use the bigger pressure spring of this elastic force on less mounting structure.
The beneficial effect that brings of the present utility model is, the compression distance that solves the existing in prior technology pressure spring is shorter, influence the space of mechanical structure, and existing improvement project has compression distance and increases the technical problem limited, that inconvenience etc. is installed, and has realized long, easy for installation, the constitutionally stable big ringlet alternative pressure spring of a kind of compression distance.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of embodiment 1 of the present utility model;
Accompanying drawing 2 is a kind of structural representations of embodiment 2 of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, the utility model is a kind of big ringlet alternative pressure spring, comprises the spring body that is made of spirality bullet circle, and spring body alternately is made of big bullet circle 1, submissile circle 2.Wherein the upper/lower terminal of spring body is big bullet circle, and big bullet circle is 4, and the submissile circle is 3, and wherein the external diameter of submissile circle is less than the internal diameter of big bullet circle.
This scheme alternately is made of big submissile circle, and the external diameter of submissile circle is less than the internal diameter of big bullet circle, so when spring stress compresses, big bullet circle is in the outside of submissile circle, when it is compressed to the limit, each big bullet circle fits, and each submissile circle makes that in the inboard applying mutually of big bullet circle the compression distance of this spring is very big.Again since the employing of this spring the structure that replaces of big submissile circle, so the stability under loading of its side direction still can be near common cylindrical spring, influenced hardly.The big bullet circle at two ends can be used to support force structure, and it is more firm to make that it can be installed.
Embodiment 2:
As shown in Figure 2, the utility model is a kind of big ringlet alternative pressure spring, comprises the spring body that is made of spirality bullet circle, and spring body alternately is made of big bullet circle 1, submissile circle 2.Wherein the upper/lower terminal of spring body is the submissile circle, and the submissile circle is 4, and big bullet circle is 3, and wherein the external diameter of submissile circle is less than the internal diameter of big bullet circle.
The submissile circle at these scheme two ends can be used to support force structure, makes it can use the bigger pressure spring of this elastic force on less mounting structure.
So the utlity model has easy for installation, structural stability, feature such as compression distance is long.
