Specific embodiment
Some vocabulary have such as been used to censure specific components in the middle of specification and claim.Those skilled in the art should
It is understood that hardware manufacturer may call same component with different nouns.This specification and claims are not with name
The difference of title is used as distinguishing the mode of component, but the difference with component functionally is used as the criterion distinguished.Such as logical
Specification and claim mentioned in " including " be an open language, therefore should be construed to " including but not limit
In ".To implement better embodiment of the present utility model, so the description is to illustrate the utility model to specification subsequent descriptions
Rule for the purpose of, be not limited to scope of the present utility model.Protection domain of the present utility model is when regarding appended power
Profit requires that the person of defining is defined.
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to restriction of the present utility model.
Embodiment 1
As shown in Figure 1-2, integral type stop nut, including nut body 1 and cyclic spring stay 11, described annular
It is integral type structure that flexible locking piece 11 is arranged on the upper end of nut body 1 with nut body 1；Described cyclic spring stay 11
Bent to the threaded inner side of nut body 1, and an annular channel 2 is formed with nut body 1；Described cyclic spring locking
The internal diameter of piece 11 is less than the threaded portion internal diameter of nut body 1 or described cyclic spring stay 11 and the threaded portion of nut body 1
Dividing has slight dislocation axially or radially.
Preferably, as shown in figure 4, in order to prevent the camber during bending of cyclic spring stay 11 excessively, described
Limited step combination 12 is additionally provided with annular channel 2.
Preferably, described limited step combination 12 is more than one semicircle step composition.
Preferably, described limited step combination 12 is the ring-shaped step composition of the complete ring-shaped step of whole piece or interruption.
Embodiment 2
It is that described cyclic spring stay 11 is provided with more than one bar shaped otch above with the difference of embodiment 1
13。
Embodiment 3
It is that described cyclic spring stay 11 sets more than one spill impression 14 above with the difference of embodiment 1.
When production and processing, as shown in figure 3, the first step, the vertical annular stay that the upper end of nut body 1 is set
11 inside lateral bending foldings, obtain non-tapping status architecture after integral type stop nut shaping as shown in Figure 5 after bending；Second
Step, screw thread process forms integral type stop nut stereochemical structure sterogram as shown in Figure 1.
In order to preferably verify the performance of integral type stop nut, carried out to the stop nut of prior art construction related
(experiment is that enchashment has in a technology and corresponding nut of the invention as foundation, in accompanying drawing 8 with M20 stop nuts to contrast test
The 15th loosening torque that product testing data, mainly first time screw-down torque and being repeated tighten after unscrewing experiment enters
Row contrast), wherein also entering after carrying out bar shaped otch 13 or spill impression 14 particular for stop nut cyclic spring stay 11
As shown in Figure 6 and Figure 7, and the bar shaped otch 13 or spill impression 14 can open up more than 1 to the corresponding Experimental Comparison of row, or even
Multiple, the utility model is opened up and is 4 states, and its compbined test data is as shown in Figure 8.
Shown according to test data, compared with prior art construction stop nut, the locking spiral shell of integral type of the present utility model
Mother take any of which form after experiment its unscrew torque decay not substantially, the structure stop nut preventing nut pine
Dynamic aspect has more remarkable result.Integral type stop nut of the present utility model mainly takes the internal diameter size of cyclic spring stay 11
Less than the threaded portion internal diameter size rope of nut body 1 mouthful form or described cyclic spring stay 11 and the spiral shell of nut body 1
There is the dislocation of slight axial direction or warp-wise line part, and the locking split nut of the structure has more particularly effect.
