And a cylindrical spring interior container 10 in which the spring 20 is embedded and sealed, using a bolt-shaped shaft 40, the cover 30, the spring 20, and the spring interior container are inserted in sequence. It is configured to be fixed to the outside of the chassis, and when one or more places where there is a possibility of a lot of shocks independently from the outside to be impacted from the outside by the anti-elasticity of the double installed spring (20) In the double shock absorber formed in this way, the spring-loaded container 10 is made of a material such as iron plate or plastic, the shaft 40 is contained Make a hole 80 in the center of the upper or lower part so that it can go and rotate the end of the spring 20 against the hole 80 so that the spring 20 enters the inside of the container, or like the cover 30. The spring 20 is inserted into a cylindrical container having a hole 80 at the center of the upper part or the lower part, and the container and the spring 20 are integrally covered with a lid having a hole 80 in the center. When the impact with the outside, the inner spring container 10 is distorted, so that the inner spring 20 is pushed back to mitigate the external shock by the anti-elasticity of the spring 20, the spring (20) Since the bolt shaft 40 is integrated with the container inside the spring interior container 10, it is also effective to prevent the outside from being pulled out by an external impact. The cover 30 also has a spring. Ashes such as interior containers When the impact with the outside, the cover 30 is crushed, so that the inner spring 20 is pushed back so as to mitigate the external shock by the anti-elasticity of the spring 20, bolt-shaped Since the shaft 40 is integrated with the spring 20, the spring 20 also has an effect of protecting the spring 20, which has a buffering effect when the external object collides with the spring 20. The spring 20 has a strong elasticity such as steel or stainless steel. It is made using a material, the spring 20 is a spring 20 so that the spring 20 is not released from the inside of the container because the force absorbing the external impact force acts differently depending on the elastic force due to its own material characteristics. By adjusting the strength of the) and at the same time to withstand the external impact force of a certain angle, when the collision with an external object, the spring 20 is pushed back and the half-burnt of the spring 20 It is characterized in that to reduce the impact force with other objects by the force. The bolt-shaped shaft 40 is made of a strong material such as iron or stainless steel, one side of the shaft head 41 and one side of the nut It is made of a used screw form, the cover 30, the spring 20 and the container by combining the integrated, by the combination of these to relieve the impact force of the external object at the same time or sequentially, and to prevent them from falling out It is done.
