Embodiment Construction

[0020] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0021] Such as figure 1 As shown, the variable spring assembly includes a top plate 1 and a bottom plate 2 facing each other and a spring body 3 vertically arranged between the top plate 1 and the bottom plate 2. There are two spring bodies 3 arranged side by side. In this embodiment, preferably, both ends of the spring body 3 are respectively fixedly connected to the top plate 1 and the bottom plate 2 by welding.

[0022] Specifically, a cylindrical body 4 is vertically provided between the two spring bodies 3 , and the lower end of the cylindrical body 4 is tightly connected to the bottom plate 2 . Preferably, the cylinder body 4 and the bottom plate 2 are sealed and fixedly connected by welding. The bottom plate 2 has...

Abstract

The invention provides a variable spring assembly, which belongs to the technical field of machinery. The variable spring assembly includes a top plate, a bottom plate, and a spring body arranged between the top plate and the bottom plate. There are two spring bodies, and a cylinder is arranged between the two spring bodies. The air outlet is connected with the barrel body, and there is a guide barrel in the barrel, the top and bottom of the guide barrel are closed and open respectively, the guide barrel is fixedly connected with the upper plate, and a seal is formed between the guide barrel and the barrel body; there is an electromagnet in the guide barrel, The electromagnet includes a shell and a main shaft, the shell protrudes from the guide barrel, and a seal is formed between the shell and the guide barrel. The iron can drive the plate to press against the lower plate and close the air outlet hole; the cylinder wall is provided with an air inlet hole, which is located between the plate body and the guide barrel, and the cylinder body is fixed with an air inlet connected to the air inlet hole. mouth. The variable spring assembly has high cushioning accuracy.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a spring, in particular to a variable spring assembly. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. [0003] Existing springs such as a compression spring disclosed in the Chinese Patent Library [Application No.: 201620912062.4] include a spring body, the two ends of the spring body are provided with end face fixing panels, the spring body is a pair of cylindrical hollow spiral bodies, and the fixing panels are with fixed The round pancake panel of the buckle of the two helical bodies of the spring body, the buckle is arranged on the outside of the spring body along the direction parallel to the central axis of the spring body. [0004] The above-mentioned compression spring realizes t...
