Abstract
The utility model discloses a rigidity degradation type compression spring, including nonmagnetic compression spring, go up the permanent magnet, down the permanent magnet, upward cut off magnet seat and cut off the magnet seat down, nonmagnetic compression spring top links firmly the permanent magnet, goes up the permanent magnet top surface and connects upward magnet seat extremely, and nonmagnetic compression spring bottom links firmly down the permanent magnet, and the magnet seat is cut off down in the connection of lower permanent magnet bottom surface, just the magnetic pole of upper and lower permanent magnet opposite face is different. The utility model discloses simple structure, reasonable in design, this compression spring's rigidity reduces along with the increase of load.
Description
Technical field
The utility model relates to a kind of spring, particularly relates to a kind of Compress Spring.
Background technique
Along with the development of all trades and professions, the application of Compress Spring is seen everywhere, well-known stage clip is the helical spring bearing pressure, its material section used mostly is circular, also useful rectangle and multiply steel are entangled and rolled, and spring is generally equal pitch, the shape of Compress Spring has: cylindrical, conical, camber and middle concave and a small amount of non-circular etc., Compress Spring and circle between have certain gap, when being subject to external load spring contraction distortion, store deformation energy.But the Compress Spring of prior art is all straight line type spring, its rigidity is a constant, can not change with load change, therefore can not meet the application requirement of some special occasions.
Therefore, how to solve the drawback that above-mentioned conventional compression spring exists, become the direction that these those skilled in the art make great efforts.
Model utility content
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of rigidity decrescence type Compress Spring, can solve the problems of the technologies described above completely.
The technical solution adopted in the utility model is:
A kind of rigidity decrescence type Compress Spring, comprise nonmagnetic Compress Spring, upper permanent magnet, lower permanent magnet, upper exhausted magnet holder and lower exhausted magnet holder, described nonmagnetic Compress Spring top is connected upper permanent magnet, upper permanent magnet end face connects upper exhausted magnet holder, nonmagnetic Compress Spring bottom is connected lower permanent magnet, lower permanent magnet bottom surface connects lower exhausted magnet holder, and the magnetic pole of described upper and lower permanent magnet opposing side is different.
As preferably, described upper and lower permanent magnet and upper and lower exhausted magnet holder are cylindrical body.
As preferably, the diameter of described exhausted magnet holder is greater than the diameter of permanent magnet, and the diameter of lower exhausted magnet holder is greater than the diameter of lower permanent magnet.
Compared with prior art, the utility model has the advantage of: structure is simple, and reasonable in design, the rigidity of this Compress Spring reduces along with the increase of load.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of rigidity decrescence type Compress Spring, comprise nonmagnetic Compress Spring 1, upper permanent magnet 2, lower permanent magnet 3, upper exhausted magnet holder 4 and lower exhausted magnet holder 5, described nonmagnetic Compress Spring 1 top is connected upper permanent magnet 2, upper permanent magnet 2 end face connects upper exhausted magnet holder 4, nonmagnetic Compress Spring 1 bottom is connected lower permanent magnet 3, and lower permanent magnet 3 bottom surface connects lower exhausted magnet holder 5, and the magnetic pole of described upper and lower permanent magnet 2,3 opposing side is different.
Described upper and lower permanent magnet 2,3 and upper and lower exhausted magnet holder 4,5 are cylindrical body.The diameter of described exhausted magnet holder 4 is greater than the diameter of permanent magnet 2, and the diameter of lower exhausted magnet holder 5 is greater than the diameter of lower permanent magnet 3.Described upper and lower exhausted magnet holder 4,5 all adopts non-magnet_conductible material to make.
The rigidity of spring is load increment dF and the ratio of incremental deformation d λ, and namely produce the load needed for unit deformation, the formula of spring rate is F '=dF/d λ.Because the magnetic pole of upper and lower permanent magnet 2,3 opposing side is different, therefore produce suction between upper and lower permanent magnet 2,3, when to spring imposed load, the amount of deformation of spring can be larger than common spring under the effect of suction, thus cause spring rate to reduce.
The rigidity of Compress Spring of the present utility model reduces along with the increase of outside imposed load, solves the problem that conventional compression spring rate cannot realize decrescence.The rigidity of Compress Spring of the present utility model reduces with the compression of spring, may be used for the performance that hydrovalve improves hydrovalve.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
