Specific embodiment
As used some vocabulary to censure specific components in the specification and claims.Those skilled in the art answer
It is understood that hardware manufacturer may call the same component with different nouns.This specification and claims are not with name
The difference of title is as the mode for distinguishing component, but with the difference of component functionally as the criterion of differentiation.Such as logical
The " comprising " of piece specification and claim mentioned in is an open language, therefore should be construed to " including but do not limit
In ".Specification subsequent descriptions are to implement better embodiment of the invention, and so the description is to illustrate general original of the invention
For the purpose of then, the range that is not intended to limit the invention.Protection scope of the present invention when regard appended claims institute's defender as
It is quasi-.
Below in conjunction with attached drawing, invention is further described in detail, but not as a limitation of the invention.
Embodiment 1
As shown in Figs. 1-2, integral type stop nut, including nut body 1 and cyclic spring lock sheet 11, the annular
The setting of flexible locking piece 11 is an integral structure in 1 upper end of nut body with nut body 1；The cyclic spring lock sheet 11
It is bent to the threaded inside of nut body 1, and forms an annular channel 2 with nut body 1；The cyclic spring locking
11 internal diameter of piece is less than 1 threaded portion internal diameter of nut body or the cyclic spring lock sheet 11 and 1 threaded portion of nut body
Dividing has slight dislocation axially or radially.
Preferably, described as shown in figure 4, camber is excessive in the process of bending for cyclic spring lock sheet 11 in order to prevent
Limited step combination 12 is additionally provided in annular channel 2.
Preferably, limited step combination 12 is more than one semicircle step composition.
Preferably, limited step combination 12 forms for whole complete ring-shaped step or intermittent ring-shaped step.
Embodiment 2
It is that the cyclic spring lock sheet 11 is provided with more than one bar shaped notch above with the difference of embodiment 1
13。
Embodiment 3
It is that more than one spill impression 14 is arranged in the cyclic spring lock sheet 11 above with the difference of embodiment 1.
When production and processing, as shown in figure 3, the first step, by the vertical annular lock sheet of 1 upper end of nut body setting
