Problems solved by technology

Different products or equipment have different requirements for the elasticity of the compression spring in different working links. If you want to change the elasticity of the compression spring without replacing the compression spring unit, you need a compression spring that can freely adjust the elasticity of the compression spring. Unit, at this stage there is no mature technical means to effectively solve this problem

Embodiment

[0026] Such as figure 1 and figure 2 As shown, a non-linear compression spring 1 unit with adjustable elastic force includes an upper compression spring 1 and a lower telescopic body. The movable support 4 on the base 5 is formed, the lower end of the compression spring 1 is fixed on the movable support 4, and a pull rope 3 is fixed in the center of the connector 2, and the pull rope 3 is along the axis of the compression spring 1 Pass through the center of the compression spring 1, continue to penetrate along the center of the movable support 4, and then be fixedly connected with the base 5; Under the action of external force, the relationship between deformation and external force is nonlinear.

[0027] The telescopic body pushes the lower end of the compression spring 1 up and down, and with the cooperation of the pull cord 3, the pre-compression amount of the compression spring 1 is changed to change the elastic force of the compression spring 1; when the telescopic bod...

Abstract

The invention discloses an elasticity-adjustable nonlinear pressure spring unit comprising a pressure spring and a telescopic body which are respectively arranged on the upper and lower portions of the nonlinear pressure spring unit. A connector is fixedly arranged at the upper end of the pressure spring, the telescopic body is composed of a base and a movable support arranged on the base, the lower portion of the spring is fixed on the movable support, a pull rope is fixed at the center of the connector, and penetrates through the center of the pressure spring along a pressure spring axis and continuously penetrates through the center of the movable support along the movable support to be fixedly connected with the base; pull rope tension is adopted to pre-compress the pressure spring without changing length of the pull rope, and under the action of external force, relationship of deformation and the external force of the pressure spring is nonlinear. The movable support moves up and down to drive the base of the pressure spring to compress or release the spring to change elastic force of the pressure spring. The movable support moves up and down stably and is operated conveniently, and the elasticity-adjustable nonlinear pressure spring unit can meet requirements for elastic mechanism application of multi-type products or equipment in different fields.

Description

technical field [0001] The invention relates to the technology in the field of spring application, in particular to a non-linear compression spring unit with adjustable elastic force. Background technique [0002] At present, the compression spring unit and the combined application of multiple compression spring units have been widely used in various fields. How to effectively realize the elastic force control of the compression spring unit is directly related to the application environment and related products of the compression spring. Different products or equipment have different requirements for the elasticity of the compression spring in different working links. If you want to change the elasticity of the compression spring without replacing the compression spring unit, you need a compression spring that can freely adjust the elasticity of the compression spring. Unit, at this stage there is no mature technical means to effectively solve this problem. Contents of the...
