Section, linkage section and the second resilient support section connection are supportted formed with upper supporting surface and bottom support surface, the diameter of upper supporting surface is with
Ratio between the diameter of supporting surface is between 0.7-1.
By using above-mentioned technical proposal, sphere elastic washer body includes linkage section and connected respectively with linkage section both ends
The the first resilient support section and the second resilient support section connect, formed with bullet between the first resilient support section and the second resilient support section
Property Support, by the resilient support area of setting, when sphere elastic washer is placed between bolt and screw, elasticity can be propped up
Support area is extruded, and flexibly supporting area can support the screw thread radial direction reverse elasticity between bolt and screw, ensure that
To the locking effect between bolt and the screw thread of screw, the further area that flexibly supports includes being arranged in the first resilient support section
The first resistance surface and the second resistance surface for being arranged in the second resilient support section, and by by the first resistance surface and second
The distance between resistance surface is between 2mm-3mm, it is ensured that the guarantee of distance between the first resistance surface and the second resistance surface, to protect
Card flexibly support area be squeezed when, first resilient support section and second resilient support section between have sufficiently long deformation away from
From, so that it is guaranteed that good using effect, and flexibly support section, linkage section and the second resilient support section connection shape by first
Into having upper supporting surface and bottom support surface, the ratio between the diameter of upper supporting surface and the diameter of bottom support surface leads between 0.7-1
To cross long-term use, improve discovery, set by using aforementioned proportion, the diameter of supporting surface and bottom support surface is set in adjustment,
Then ensure good support effect and ensure that good connection effect between bolt and screw, and it is up-small and down-big
Setting, then further increase elastic effect.
The utility model is further arranged to：Junction between the linkage section and the first resilient support section is formed with the
One joint face, the junction between linkage section and the second resilient support section is formed with the second joint face, the first joint face and lower branch
Junction between support face is in arc-shaped, and the junction between the second joint face and bottom support surface is in arc-shaped.
By using above-mentioned technical proposal, the junction between linkage section and the first resilient support section is formed with the first connection
Face, the junction between linkage section and the second resilient support section is formed with the second joint face, by by the first joint face and lower branch
Junction between support face is arranged to arc-shaped and is in arc-shaped by the junction between the second joint face and bottom support surface, because
It can cause in linkage section and the first resilient support section and linkage section and the second resilient support section stress for convex structure
When, there is the resilient support effect of circular arc, so that it is guaranteed that the structural strength in sphere elastic washer stress.
The utility model is further arranged to：The resilient support area is oblique.
By using above-mentioned technical proposal, resilient support area is oblique, because sphere elastic washer is to place
Between bolt and connected body, since it is desired that by connection of the elasticity in resilient support area to the screw thread between bolt and screw
Compactness, in sphere elastic washer both ends stress, by the way that resilient support area is arranged into skewed so that sphere elastic washer
Uniform force, so as to ensure that good resilient support effect.

Embodiment
A kind of sphere elastic washer embodiment of the utility model is described further referring to figs. 1 to Fig. 2.
As shown in figure 1, a kind of sphere elastic washer, including sphere elastic washer body, sphere elastic washer body include
Linkage section 1 and the first resilient support section 2 and second being connected respectively with the both ends of linkage section 1 flexibly support section 3, the first elasticity branch
Support section 2 and second to flexibly support between section 3 formed with resilient support area 4, by the resilient support area 4 of setting, by sphere bullet
Property packing ring when being placed between bolt and screw, resilient support area 4 can be extruded, and bolt and spiral shell can be made by flexibly supporting area 4
Screw thread radial direction reverse elasticity support between hole, ensures that to the locking effect between bolt and the screw thread of screw, enters one
The resilient support area 4 of step includes the first resistance surface 40 being arranged in the first resilient support section 2 and is arranged at the second elasticity branch
Support section 3 on the second resistance surface 41, and by by the distance between the first resistance surface 40 and the second resistance surface 41 in 2mm-3mm
Between, it is ensured that the guarantee of distance between the first resistance surface 40 and the second resistance surface 41, to ensure in resilient support area 4 by crowded
During pressure, the first resilient support section 2 and second has sufficiently long deformation distance between flexibly supporting section 3, so that it is guaranteed that good makes
With effect, as shown in Fig. 2 and flexibly support section 2 by first, linkage section 1 and second flexibly supports section 3 and connected formed with upper
Supporting surface 10 and bottom support surface 11, the ratio between the diameter of upper supporting surface 10 and the diameter of bottom support surface 11 between 0.7-1,
By long-term use, discovery is improved, is set by using aforementioned proportion, the diameter of supporting surface 10 and bottom support surface 11 in adjustment
Set, then ensure good support effect and ensure that good connection effect between bolt and screw, and on
Small lower big setting, then further increase elastic effect.
As shown in Fig. 2 the utility model is further arranged to, linkage section 1 and first flexibly supports the junction between section 2
