Description
Technical field
The utility model belongs to fastening device technical field, relates in particular to a kind of interior twisting nut.
Background technology
Nut is one of common fastener, mainly passes through the internal thread of its threaded hole and bolt, stud（Stud）It is outer
Thread fitting plays the role of fastening after screwing.It is widely used in production and living.Relatively conventional nut has：Hex nut, six
Angle flange face nut, 12 angle flange face nuts, Closely locking nut and sides nut, round nut etc., nut type is various, shape
It is different.
At present, the twisting position of common nut is predominantly located in outer surface, i.e. the surface at twisting position surrounds nut entity
All or part, be outer twisting nut.Twisting position such as hex nut, hexagon nut with flange and Closely locking nut is outer six
Side, a part for nut are surrounded by 6 faces of outer six side, and the twisting position of 12 angle flange face nuts is outer 12 jiaos, spiral shell
A female part is surrounded by outer 24 faces of bihexagonal.Although outer twisting nut using relatively broad, is asked there are following
Topic：First, installation space must reserve the working space of twisting tool in diametric(al)；Second is that nut portion is not easy to hide；
Third, landscaping effect is poor.
Invention content
A kind of saving space for being there is provided the purpose of the utility model is to overcome disadvantages mentioned above, convenient for hiding, structure letter
Single, easy to operate interior twisting nut.
The utility model aim and its technical problem underlying is solved using following technical scheme to realize：
The interior twisting nut of the utility model, including nut, nut blanking cover, wherein：The outer circumference surface of nut is single circle
Cylinder or step circles cylinder, nut interior are provided with internal thread chamber and twisting working chamber, are removably installed in twisting working chamber
There is a nut blanking cover, nut blanking cover is divided into disk and shank, and shank is with being set in twisting working chamber.
Above-mentioned interior twisting nut, wherein：The radial section of twisting working chamber side is interior hexagon, interior hexagonal flower-shape, three
Prismatic or four prism type.
Above-mentioned interior twisting nut, wherein：The radial section of the shank lateral surface of nut blanking cover be and twisting working chamber side
Corresponding outer hexagon, outer-hexagonal flower-shape, triangular prism shaped or four prism type.
The utility model compared with the existing technology has clear advantage and advantageous effect.By above technical scheme it is found that
In the interior twisting nut of the utility model, nut interior is provided with internal thread chamber and twisting working chamber, twisting working chamber side
Radial section is interior hexagon, interior hexagonal flower-shape, triangular prism shaped or four prism type can be set different according to different demands
Shape, it is highly practical；Nut blanking cover is removably installed in twisting working chamber, the radial direction of the shank lateral surface of nut blanking cover is cut
Face is outer hexagon corresponding with twisting working chamber side, outer-hexagonal flower-shape, triangular prism shaped or four prism type, and nut blanking cover is
Optional part, when use, can play the role of beautification, hidden nut.In short, the utility model save space, convenient for hide,
Simple in structure, easy to operate, twisting promotes the use of in suitable nut.

Specific embodiment
Below in conjunction with attached drawing and preferred embodiment, to according to the utility model proposes interior twisting nut specific embodiment party
Formula, structure, feature and its effect are described in detail as after.
Referring to Fig. 1 to Fig. 9, the interior twisting nut of the utility model, including nut 2, nut blanking cover 4, wherein：Nut 2
Outer circumference surface is single cylindrical surface or step circles cylinder, and nut 2 is internally provided with internal thread chamber 1 and twisting working chamber 3, twisting work
Make to be removably installed nut blanking cover 4 in chamber 3, nut blanking cover 4 divides for disk and shank, and shank is with being set in twisting work
In chamber 3.The radial section of 3 side of twisting working chamber is interior hexagon, interior hexagonal flower-shape, triangular prism shaped or four prism type.Nut
The radial section of the shank lateral surface of blanking cover 4 is outer hexagon corresponding with 3 side of twisting working chamber, outer-hexagonal flower-shape, three
Prismatic or four prism type.
In use, referring to Figure 10, the small column intracavitary that bolt 6 is fitted into interlayer 5, nut 2 is fitted into the great circle in interlayer 5
Column intracavitary makes internal thread chamber 1 be directed at the external thread section of bolt 6, is stretched into twisting working chamber 3 and is exerted a force using suitable tool,
Bolt 6 is made, with cover screwing, then to choose suitable nut blanking cover 4 with nut 2 and be packed into twisting working chamber 3.
When designing and manufacturing nut 2, the depth of twisting working chamber 3 is the 0.5 of the circumscribed circular diameter of twisting face radial section
Times and more than, the reach of internal thread chamber 1 for 0.5 times of Major Diam and more than, excircle dimension size is according to use occasion
Space determine, but should ensure that with enough intensity.When designing and manufacturing nut blanking cover 4, the disk diameter of nut blanking cover 4
It is consistent with the maximum gauge of 2 outer circle of nut, the radial direction of the cross sectional shape and size and twisting working face in twisting working chamber 3 of shank
Cross sectional shape and size match, the length of shank for 0.5 times of the circumscribed circular diameter of radial section and more than, shank is according to installation
Situation sets cylindrical lumens.The utility model saves space, convenient for hiding, simple in structure, easy to operate, is pulled in suitable nut
Stubborn promotes the use of.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, it is any without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model to above example
Any simple modification, equivalent change and modification made, in the range of still falling within technical solutions of the utility model.
