Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Number and corresponding component title represented by letter in figure:
1. 2. nylon ring of nut body, 3. screw rod
4. 5. antislip ring of support ring.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
In conjunction with Fig. 1, the utility model discloses a kind of stop nuts, including the nut body 1 cooperated with screw.In nut
1 center of ontology is provided with tapped through hole；Hollow boss is provided on nut body 1.Boss is located at the top of tapped through hole.
Be provided in boss axially through cylindrical accommodating cavity, the nylon ring 2 of ring structure is installed in accommodating cavity body.
Nylon ring 2 is made of nylon material.Nylon ring 2 and screw are interference fitted.The inner hole lower end of nylon ring 2 is provided with downward expansion
Tubaeform chamfering.Annular groove is provided on the outside of screw through-hole；Annular groove is located at the lower end surface of nut body 1.In ring
Stacked up and down support ring 4 and antislip ring 5 are installed in shape slot.Support ring 4 is located at the top of antislip ring 5.Support ring 4 can adopt
