Abstract

The utility model discloses a composite extension spring comprising a first spring and a second spring which are homocentric. The composite extension spring is characterized in that the second spring is arranged in the first spring ring in a sleeved mode, the second spring is smaller than the first spring in length and stiffness coefficient, the inner diameter of the first spring is bigger than the outer diameter of the second spring, one end of the first spring is parallel and level with one end of the second spring, the inner diameter of a port of the other end of the first spring is smaller than the outer diameter of the second spring, and the elastic deformation length of the second spring is bigger than the length of the first spring. Springs with different stiffness coefficients are arranged homocentrically, the spring with a small stiffness coefficient is arranged in the spring with a large stiffness coefficient, the spring with the small stiffness coefficient is extended to elastically deform to different lengths, and therefore the springs with the different stiffness coefficients are controlled. The composite extension spring has the advantages of being capable of accurately measuring small force and large force at the same time, and enlarging the application range of the springs.

Description

A kind of compound extension spring
Technical field
The utility model relates to a kind of novel compound extension spring.
Background technique
Be widely used in dynamometer spring at present and according to [coefficient of its measured value range accurately arranged usually; The spring that [coefficient of is bigger can only be used to measure and its progress coefficient bigger power that is complementary, and is difficult to accurately measure less relatively power, and the less spring of [coefficient of can only accurately be measured and its progress coefficient less power mutually; The relatively large power of energy measurement not; This has just limited the Applicable scope of this spring, also the using scope of the end product of restriction, for example spring balance.
Summary of the invention
The utility model provides a kind of multiduty NEW TYPE OF COMPOSITE extension spring for solving the problem that existing technology in use exists.
The technological scheme that the utility model solves existing issue is: a kind of compound extension spring; Comprise the first concentric spring, second spring, as improvement, described length, [coefficient of are located in first spring ring less than second spring housing of first spring; Described first spring inside diameter is greater than the second spring external diameter; First spring and second spring one are held level with both hands together, and the other end port internal diameter is less than the external diameter of second spring, and the elastic strain length of second spring is greater than the length of first spring.
As further improvement, the spring thread that described first spring, second spring are differed by an external diameter is reeled and is formed, and its joint is positioned at a concordant end.
As further improvement, described second spring is positioned at the inboard end of first spring and is fixed with the body of rod that band draws mouth.
The utility model compared with prior art; Spring through [coefficient of is differed is provided with one heart, and the less spring of [coefficient of is built in the bigger spring of [coefficient of, through little spring deformation to the different length of tensile stiffness coefficient; To control the spring of different [coefficient ofs; Its beneficial effect is when can accurately measure less power, also can measure bigger power, enlarges the Applicable scope of spring.
Description of drawings
Fig. 1 is the structural scheme of mechanism of the utility model.
Embodiment
Referring to Fig. 1; This case study on implementation comprises the first concentric spring 1 and second spring 2; Length, [coefficient of are located in first spring ring 1 less than second spring housing 2 of first spring 1, and first spring, 1 internal diameter is greater than second spring, 2 external diameters, and first spring 1 and second spring 2 one are held level with both hands together; The other end port internal diameter is less than the external diameter of second spring 2, and the elastic strain length of second spring 2 is greater than the length of first spring 1.The second less spring 2 of [coefficient of stretches, and is used for accurately measuring and the less power of its coupling, further is stretched to the port of first spring 1, and two springs mutually also can be used to measure relatively large power.
For simplified structure with improve applicability, the spring thread that first spring 1, second spring 2 are differed by an external diameter is reeled and is formed, its joint is positioned at a concordant end; And second spring 2 is positioned at the inboard end of first spring 1 and is fixed with the body of rod 3 that band draws mouthful, makes things convenient for connecting body to be connected with spring.
