Screwed hole 2 is provided with maternal body 1, also including two " L " shape switch blocks 3；The bottom in " I " portion of " L " the shape switch block 3 is fillet 4；
"-" portion inner face of " L " the shape switch block 3 is provided with array multiple raised 5；Symmetrically two are provided with the nut body 1
Level trough 6；The level trough 6 is communicated with the external world；The vertical appearance communicated with each level trough 6 is also provided with the nut body 1
Receive groove 7；The bottom of the holding tank 7 is provided with the cylinder 8 that expansion link is protruded upward；The telescopic rod end of the cylinder 8 is provided with and pushes away
Block 9；The lower surface of the nut body 1 is provided with the switch 10 of control cylinder 8；" I " portion of each " L " shape switch block 3 holds
It is contained in a holding tank 7, the bottom in " I " portion of " L " the shape switch block 3 is in contact with pushing block 9；" L " the shape switch block 3
" I " portion is contained in when in holding tank 7, and "-" portion of " L " the shape switch block is located in level trough 6, "-" of " L " the shape switch block 3
Portion upper surface and the upper surface flush of nut body 1, "-" portion lateral surface of " L " the shape switch block 3 is towards the direction of screwed hole 2；Institute
State the width of the width more than " L " shape switch block 3 of level trough 6；" I " portion of " L " the shape switch block 3 can glide on holding tank 7 is interior
It is dynamic；When " I " portion of " L " the shape switch block 3 slides up to extreme higher position, can downwardly turn over；" I " portion of " L " the shape switch block 3
In level trough 6, "-" portion of " L " the shape switch block 3 and the diameter parallel of screwed hole 2；In said structure, described each appearance
Groove 7 of receiving is interior to be provided with two annular grooves 11；The both sides in " I " portion of " L " the shape switch block 3 are provided with cylindrical slider 12；The cunning
Block 12 is slided in chute 11, and " I " portion of " L " shape switch block 3 slides up and down in holding tank 7, and when sliding into extreme higher position, can
Downwardly turn over；"-" portion of " L " the shape switch block 3 includes fixed block 13, contiguous block 14 and elastomeric element 15；The contiguous block 14
It is arranged on the inner end of fixed block 13；The connection fixing block 13 of the elastomeric element 15 and contiguous block 14；Raised 6 company of being arranged on
Connect the inner face of block 14；Because gap is left in raised 5 bottoms and the bottom of level trough 6, it is ensured that raised 5 not with water
6 bottoms generation of rising as high as the banks is touched, it is to avoid raised 5 are worn.
Of the present invention a kind of automatic elastic stop nut as shown in accompanying drawing 3,4, when using, the screw rod of bolt 16 is inserted
After entering sheet material 17, switch 10 is pressed, the expansion link of cylinder 8 stretches out, drive pushing block 9 to release two " I " portions of " L " shape switch block 3
Holding tank 7, then overturns two " L " shape switch blocks 3 so that " I " portion of " L " shape switch block 3 is located in level trough 6, then spiral shell
Maternal body 1 screws on the screw rod of bolt 16, and after screwing, raised 6 bottom contacts with the both side surface of sheet material 17, plays increase and rubs
The effect of power is wiped, when plant equipment operation produces mechanical oscillation, nut is difficult to rock so that screw thread is not easy to wear, increased
Fastening effect, improves the service behaviour and stability of plant equipment, so that some precision equipment machining accuracies are obtained
Ensure, more prevent bolt to deviate from the generation of nut thread hole phenomenon, improve the security performance of plant equipment；Using finishing
Afterwards, nut body is unloaded, switch is then pressed, the expansion link of cylinder is shunk, and " I " portion of two " L " shape switch blocks 1 is put into receiving
