Description
Technical field
The utility model relates to spring art, particularly relates to a kind of high tenacity extension spring.
Background technique
Spring is a kind of mechanical parts utilizing elasticity to carry out work.There is deformation under external force with the part that elastic material is made, restore to the original state again after removing external force.Also " spring " is made.General spring steel is made.The kind complexity of spring is various, divides by shape, mainly contains helical spring, spiral spring, leaf spring, heterotypic spring etc.
Summary of the invention
The technical problem that the utility model mainly solves is to provide a kind of high tenacity extension spring, and structure is simple, and inside is provided with multi-layer structure, increases the toughness of spring, not easily produces the phenomenon fractureing and damage, and prolongation uses practical, and financial cost is cheap.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of high tenacity extension spring, comprise spring body, elasitic layer and buffer layer, the inside of described spring body is provided with filling slot, described elasitic layer is filled in the inside of filling slot, the inside of described filling slot is provided with buffer layer, and described buffer layer is located at the centre of spring body and elasitic layer, and described buffer layer is connected by tackiness agent with elasitic layer.
In the utility model preferred embodiment, the diameter of described spring body is 5-7mm.
In the utility model preferred embodiment, the material of described spring body is high carbon steel.
In the utility model preferred embodiment, described elasitic layer is threaded-structure.
The beneficial effects of the utility model are: a kind of high tenacity extension spring of the utility model, and structure is simple, and inside is provided with multi-layer structure, and the toughness of increase spring, not easily produces the phenomenon fractureing and damage, and extend and use practicality, financial cost is cheap.
