Referring to fig. 1-6, the present invention provides a technical solution:

a highly pressure-resistant wave spring comprises a wave spring body 1, wherein the wave spring body 1 comprises a pair of flat rings 11 and a plurality of wave rings 12 tightly welded between the two flat rings 11, and the end faces of the outer sides of the flat rings 11 are attached to the surfaces of objects, so that the wave spring body 1 can be stressed uniformly among the objects. The top surface position department of wave form circle 12 is upwards protruding and is formed a plurality of crests, the bottom surface position department of wave form circle 12 is protruding downwards and is formed a plurality of troughs, the crest of present wave form circle 12 and the trough of the adjacent wave form circle 12 that is located the top are closely welded, make between two adjacent wave form circles 12 closely welded together, use crest and trough looks welded mode through making two adjacent wave form circles 12, can make and form great space between two wave form circles 12, so that wave spring main part 1 can be compressed when receiving axial pressure, thereby make wave form circle 12 take place to warp and produce elasticity.

In this embodiment, a plurality of node fixtures 2 are tightly welded between two adjacent wave rings 12, and each node fixture 2 includes a base 21 located inside the wave spring main body 1, a pair of protruding columns 22 integrally formed on the outer end surface of the base 21, and a pair of water drop columns 23 integrally formed on the outer end surface of the base 21. An embedded groove 24 is formed between the two convex columns 22 and the two water drop columns 23, and the joint of the two adjacent wave-shaped rings 12 is embedded in the embedded groove 24. Two convex columns 22 distribute in the top of base 21 both sides respectively, two convex columns 22 are located the top of two adjacent wave form circle 12 junctions both sides respectively, two water droplet posts 23 distribute in the left and right sides of base 21 respectively, two water droplet posts 23 are located the left and right sides of two adjacent wave form circle 12 junctions respectively, make the junction that the welding is in the same place between two adjacent wave form circles 12 can be spacing by node fixation ware 2, make the position between two adjacent wave form circles 12 restricted by node fixation ware 2, appear the condition emergence that wave form circle 12 takes place the dislocation when the solder joint that prevents between two adjacent wave form circles 12 splits, make wave form spring main part 1 remain elasticity throughout.

Specifically, the outside corner of water droplet post 23 is the radius horn shape, when making wave spring main part 1 receive the compression, can not produce with the corner of water droplet post 23 when wave form circle 12 produces deformation and interfere to prevent that wave form circle 12 from carrying out elastic deformation time because of being supported and producing the phenomenon of buckling by the corner of water droplet post 23.

Furthermore, a plurality of node fixers 2 located on the same horizontal plane are distributed on the corrugated ring 12 in a central symmetry manner, so that the node fixers 2 can be distributed on the corrugated spring main body 1 in a symmetrical manner, and therefore when the corrugated spring main body 1 is pressed, each layer of corrugated ring 12 on the corrugated spring main body 1 can be uniformly stressed.

In addition, be between vertical two adjacent node fixer 2 inseparable welding have increase shell fragment 3, it is the column structure of bending to increase shell fragment 3, it has fixed chimb 31 to increase the first and last both ends homogeneous body bending shaping of shell fragment 3, fixed chimb 31 and the inseparable welding of projection 22, make wave spring main part 1 when the atress is compressed, it draws close to each other to be vertical two adjacent node fixer 2, it is compressed to make, it provides extra elasticity to make to increase shell fragment 3 for wave spring main part 1, increase the compressive capacity of wave spring main part 1, make wave spring main part 1 can resume the original state under the high pressure, thereby make wave spring main part 1 can normal use.

When the highly pressure-resistant wave spring of the embodiment is used, firstly, as the wave spring body 1 is subjected to high pressure, the wave spring body 1 is compressed, the distance between two adjacent wave rings 12 is shortened, then, as the distance between two adjacent wave-shaped rings 12 is shortened, two node fixing devices 2 which are longitudinally adjacent are mutually closed, at the moment, the elastic increasing sheets 3 are compressed, thereby the spring increasing sheet 3 provides extra elastic force for the wave spring main body 1, the pressure resistance of the wave spring main body 1 is increased, finally when high pressure is repeatedly acted on the wave spring main body 1 to cause the wave ring 12 to generate repeated deformation, the weld between two adjacent undulating rings 12 may break, where under the constraint of the node anchor 2, the two broken wave-shaped rings 12 at the welding position are still limited by the node fixer 2, and the situation that the overall elasticity of the wave-shaped spring body 1 is reduced due to dislocation of the wave-shaped rings 12 is prevented.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
