Description
Technical field
The invention belongs to nut technical fields, and in particular to a kind of dissection type nut.
Background technology
Plain nut is since its structure limits, and in use, efficiency of assembling is than relatively low.In machinery, automobile, aviation boat
My god, construction industry field is when largely using bolts assemblies, particularly under the operating modes such as threaded bar after long threaded bar, corrosion, i.e.,
Using Pneumatic screw driver, operation is still cumbersome, and efficiency is still than relatively low, it is impossible to meet extensive, mass production assembling
Use demand.
The content of the invention
In view of the problems of the existing technology, fastening effect can quickly be performed it is an object of the invention to provide a kind of
Dissection type nut.
To achieve the above object, the technical solution that the present invention takes is as follows：
Dissection type nut：Including left half-nut and right half-nut, the screw initial thread position phase of left half-nut and right half-nut inner wall
Poor half pitch（To ensure to form a complete screw thread after the assembling of two half-nuts）, the correspondence of left half-nut and right half-nut
Both ends be the boss that is adapted and notch i.e.：One end of left half-nut is convex platform and lower notch, right half-nut and left half-nut
For the corresponding one end in this end then for upper notch and lower convex platform, the other end of left half-nut is upper notch and lower convex platform, right half-nut with
The corresponding one end in this end of left half-nut is then convex platform and lower notch, and left half-nut and right half-nut opposite ends convex platform
Bottom surface and the top surface of lower convex platform be the arc-shaped curved surface being adapted；The opposite ends of left half-nut and right half-nut are by being adapted
Boss and notch and arc-shaped curved surface locking for a nut entirety.
Due to the design of arc-shaped curved surface, left half-nut and right half-nut can be along arc-shaped curved surface, unidirectional exercise groups
It closes, in the case of no locking device, two nuts can also be tightly snapped together, without being pulled open by horizontal force.Certainly,
The locking device that can be adapted on left half-nut and right half-nut with otherwise designed.
The locking device being adapted can take one kind in the forms such as closing piece-lockhole, pin, spring, ball or
Two or more combinations.
When the locking device being adapted takes closing piece-lockhole form, specific setting structure is：Left half-nut
One end convex platform bottom sets closing piece, and right half-nut one end lower convex platform top corresponding with this end of left half-nut is corresponding with this closing piece
Position lockhole is set, lockhole is set at the top of the other end lower convex platform of left half-nut, this end is corresponding with left half-nut for right half-nut
Corresponding with this lockhole position in one end convex platform bottom closing piece is set.
For convenience of differentiation, Fast Installation is realized, the top surface of any one is equipped with identification technique in left half-nut, right half-nut
Hole.
Left half-nut and right half-nut by stainless steel, copper alloy, brass, aluminium, titanium alloy either ceramics using casting or
Turnning and milling mode is made.
In the present invention, on the premise of left half-nut and right half-nut both ends are kept in the same direction, each half-nut is with its inner wall
Screw thread, to whether there is identification fabrication hole be characteristic, and in addition, the two shape can be identical i.e. convex in two half-nuts at this time
Platform, lower notch, upper notch, the shape of lower convex platform and size are completely the same）, can not also identical convex platform i.e. in two half-nuts,
Lower notch, upper notch, the shape of lower convex platform and size are not quite identical, but due to two half-nut opposite ends boss and lack
Mouth is adapted, therefore still can ensure to be assembled into a nut entirety.
For the present invention due to the design of arc-shaped curved surface, left half-nut and right half-nut can be unidirectional along arc-shaped curved surface
Movement combination, after fastening, two half-nuts are tightly stuck, are quickly performed fastening effect by bidirectional obstruction.The present invention by
In its design feature, also with following peculiar advantage：
1st, in long threaded bar, main purpose is saved by quite fast and easy installation and removal dissection type nut
It saves time.
2nd, install and repair the pipe fitting hardly entered or equipment.
3rd, on impaired or corrosion bolt, since dissection type nut only needs minimum spiral shell on restraint location
Line length can fix, so being damaged or can not use part that can set aside, not influence to use.
4th, the repair available for equipment in such as Military Application under the conditions of heavy corrosion and explosion-proof environment.
5th, can be as the auxiliary device of threaded bar top nut, and do not have to move other component first.
6th, dissection type nut is a perfect design for vacuum application, because its reach can be reduced to absolutely
To minimum value, bolt may need the length grown very much or even fracture or bend to can be only achieved purpose, but use dissection type spiral shell
It is female, it is only necessary to can to achieve the goal in the fixed position use of expectation.

Specific embodiment
As shown in figs. 1-7, dissection type nut：Left half-nut 1 and right half made of including using turnning and milling mode by stainless steel
Nut 2, the top surface of left half-nut 1 are equipped with identification fabrication hole 10, the screw initial thread position of 2 inner wall of left half-nut 1 and right half-nut
Differ half pitch, the opposite ends of left half-nut 1 and right half-nut 2 be the boss that is adapted and notch i.e.：Left half-nut 1
Front end is the first convex platform 3 and first time notch 4, and rear end is 5 and first lower convex platform 6 of notch on first, accordingly, right half-nut
2 front end is notch and the second lower convex platform on second, and rear end is the second convex platform and second time notch；Also, the first convex platform 3
Bottom surface for the first arc-shaped curved surface 7 and be provided with the first closing piece 8, the top surface of the first lower convex platform 6 for the second arc-shaped curved surface and is set
There is the first lockhole 9, the top surface of the second lower convex platform is the 3rd arc-shaped curved surface being adapted with the first arc-shaped curved surface 7 and is provided with and the
The second lockhole that one closing piece 8 is adapted, the bottom surface of the second convex platform are the 4th arc-shaped curved surface being adapted with the second arc-shaped curved surface
And it is provided with the second closing piece being adapted with the first lockhole 9.
In use, the both ends of left half-nut 1 and right half-nut 2 is kept to correspond to, pass through（First convex platform 3 and first time lack
Mouth 4）With（Notch and the second lower convex platform on second）、（5 and first lower convex platform 6 of notch on first）With（Second convex platform and second
Lower notch）, the first arc-shaped curved surface 7 and the 3rd arc-shaped curved surface, the second arc-shaped curved surface and the 4th arc-shaped curved surface, the first closing piece 8 and
Locking is adapted to as a nut entirety between two lockholes, the first lockhole 9 and the second closing piece（As shown in Figs. 1-3）.
Embodiment of above is the preferred embodiment of the present invention, i.e., before left half-nut and right half-nut both ends are kept in the same direction
Put, each half-nut using its inner thread, whether there is identification fabrication hole as characteristic, in addition, the two shape is identical, therefore
Omit the structure diagram of right half-nut.
