Description
Technical field
The utility model relates to the technical field of threaded connector in mechanical structure, in particular to a kind of positive and negative silk consubstantiality spiral shell
It is female.
Background technique
What we usually saw is nearly all the nut of unidirectional screw thread or is forward leading nut (Fig. 2) or is anti-silk spiral shell
Female (Fig. 3), and the screw rod of double thread is very common, when encountering the screw rod of opposite rotation direction screw thread using unidirectional screw nut, no
Needing for a period of time can be solved.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of same body nut of positive and negative silk.
The technical solution of the utility model is: a kind of positive and negative same body nut of silk, including nut body, the nut body
Inner hole is equipped with left and right, the thread section first being staggered up and down and thread Duan Yi, and the side of the thread section first is screw thread
The side of slot Duan Yi, the thread Duan Yi are thread groove section first, are between the thread section first and the thread Duan Yi
Public thread groove section, the thread groove section first and the thread groove Duan Yi are connected to by public thread groove section.
Preferably, the thread section second of its lower right the thread Duan Jiayu forms forward screw thread tooth, the thread groove
The thread groove section first of its lower right Duan Yiyu forms forward screw thread slot, the thread section first of its lower left the thread Duan Yiyu
Reverse thread tooth is formed, the thread groove section second of its lower left the thread groove Duan Jiayu forms reverse thread slot.
Preferably, thread groove Duan Yi or more described in the thread Duan Jiayu is staggered, the thread Duan Yiyu institute
Stating thread groove section first is also to be staggered up and down.
Preferably, thread groove section first described in the thread Duan Jiayu or so is aligned, spiral shell described in the thread Duan Yiyu
Groove section second or so alignment.
The beneficial effects of the utility model are:
A kind of positive and negative same body nut of silk of the utility model can be applicable in the screw rod of positive silk or anti-silk, convenient, practical,
When the mechanical structure especially assembled at the same time using a large amount of forward leading screws and backward leading screw, forward leading screw and backward leading screw are easy
It mixes up, it can be very convenient with body nut using the positive and negative silk of the utility model.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model；
Fig. 2 is the schematic cross-sectional view of forward leading nut；
Fig. 3 is the schematic cross-sectional view of anti-silk nut；
In figure: 1. ontologies, 11. thread section first, 12. thread Duan Yi, 13. thread groove section first, 14. thread groove Duan Yi,
15. public thread groove section.
Specific embodiment
Specific embodiment of the present utility model is referring to Fig. 1:
A kind of same body nut of positive and negative silk, such as Fig. 1, including nut body 1, the inner hole of nut body 1 are equipped with left and right, hand over up and down
The thread section first 11 and thread section second 12 of mistake setting, the side of thread section first 11 are thread groove section second 14, thread section
The side of second 12 is thread groove section first 13, is public thread groove section 15, screw thread between thread section first 11 and thread section second 12
Slot section first 13 is connected to thread groove section second 14 by public thread groove section 15.
The positive and negative silk can be applicable in the screw rod of positive silk or anti-silk with body nut, convenient, practical, especially use at the same time
When a large amount of forward leading screws and the mechanical structure of backward leading screw assembling, forward leading screw and backward leading screw are easy to mix up, practical using this
Novel positive and negative silk can be very convenient with body nut, can be applicable in forward leading screw or backward leading screw simultaneously.
The positive and negative silk also facilitates with the production of body nut, after nut body 1 is processed into common forward leading nut, then reversely attacks
Silk attacks the intersection of reverse thread slot and forward screw thread tooth to form public thread groove section 15, and forward screw thread tooth is separated
The thread section first 11 and thread section second 12 of diamondwise；Or nut body 1 is first processed into common anti-silk nut, such as scheme
3, then positive tapping, it attacks the intersection of forward screw thread slot and reverse thread tooth to form public thread groove section 15, reversed spiral shell
Line tooth is divided into the thread section first 11 and thread section second 12 of diamond shape；It is practical new that above two processing method can obtain this
The same body nut of positive and negative Soviet Union of type；In the positive and negative silk in body nut, the thread section second 12 of thread section first 11 and its lower right
Form forward screw thread tooth, the formation forward screw thread slot of thread groove section first 13 of thread groove section second 14 and its lower right, thread Duan Yi
The formation reverse thread tooth of thread section first 11 of 12 and its lower left, the thread groove section second 14 of thread groove section first 13 and its lower left
Reverse thread slot is formed, thread section first 11 is staggered with about 14 thread groove section second, thread section second 12 and thread groove section
First 13 also to be staggered up and down, and thread section first 11 is aligned with thread groove section first 13 or so, thread section second 12 and thread groove
Section second 14 or so is aligned.
