Abstract
The utility model discloses a screw cap, be in including screw cap body, formation cavity in the screw cap, screw cap still includes: formation is in the balanced spigot surface of cavity internal surface, balanced spigot surface is located the end of cavity for improve the concentricity of screw cap fastening back and quilt fastening object, the screw thread, the screw thread is located the cavity internal surface, by the screw cap front end run through to balanced spigot surface one end, this utility model can be balanced to minimum with the screw deviation voluntarily, and terminal surface complex precision has meanwhile been improved to improvement screw cap fastening back and the concentricity of being fastened the object, has increased by the clamping -force of fastening object, improves stability.
Description
Technical field
This utility model relates to a kind of nut.
Background technology
Existing nut is that nut screw thread self guides mostly, position to realize clamping by screw thread and end face with by securing objects, one drawback of this mode be screw thread itself accuracy error with can be reduced by the chucking power of securing objects and stability by the accuracy error of securing objects end face, when nut needs to run in the environment of running up, precision not and is stablized and poor all can be caused puzzlement in the course of processing.It is very important it is thus desirable to solve this problem.
Summary of the invention
In view of this, needing to overcome at least one in drawbacks described above of the prior art, this utility model provides a kind of nut.
Described nut, including nut body, the cavity that is formed in described nut, described nut also includes the stable steering face being formed at described cavity inner surface, and described stable steering face is positioned at the end of described cavity, in order to improve nut fastening after with by the concentricity of securing objects；Screw thread, described screw thread is positioned at described cavity inner surface, described nut front end be through to one end, described stable steering face.
According in this patent background technology to described in prior art, existing nut is that nut screw thread self guides mostly, with by securing objects by screw thread and end face location to realize clamping, but the accuracy error of screw thread itself and being reduced by the chucking power of securing objects and stability by the accuracy error of securing objects end face；And this utility model sets up one section of stable steering face at the cavity end within nut, with by coordinating of the surface of securing objects, screw thread deviation can be equilibrated to minimum by stable steering face in nut fastener cycle, improve nut fastening after with by the concentricity of securing objects, meanwhile improve the precision that end face coordinates, increase by the chucking power of securing objects, improve stability, therefore there is clear advantage.
It addition, according to nut disclosed in this utility model also there is following additional technical feature:
Further, described nut also includes that stress surface, described stress surface are connected with described cavity end, and the axisymmetric position of described stress surface is provided with in order to through by the through hole of securing objects.
Further, described nut is circular.
Aspect and advantage that this utility model is additional will part be given in the following description, and part will become apparent from the description below, or is recognized by practice of the present utility model.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present utility model and advantage will be apparent from easy to understand from the following description of the accompanying drawings of embodiments, wherein:
Fig. 1 is nut generalized section；
Fig. 2 is nut overall schematic.
In Fig. 1,1 screw thread, 2 stable steering faces, 3 stress surfaces, 4 through holes, 5 nut body, 6 cavitys.
Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, and the most same or similar label represents same or similar element or has the element of same or like function.The embodiment described below with reference to accompanying drawing is exemplary, is only used for explaining this utility model, and can not be construed to restriction of the present utility model.
In description of the present utility model, it will be appreciated that, term " on ", D score, " end ", " top ", "front", "rear", " interior ", " outward ", " horizontal ", the orientation of the instruction such as " erecting " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of description this utility model and simplifies description, rather than instruction or the device of hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " couples ", " connection ", " being connected ", should be interpreted broadly " connection ", " cooperation ", connects for example, it may be fixing, it is integrally connected, it is also possible to be to removably connect；It can be the connection of two element internals；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary；" coordinating " can be face and the coordinating of face, it is also possible to is point and the coordinating of face or line and face, also includes the cooperation of hole axle, for the ordinary skill in the art, and can be with concrete condition understanding above-mentioned term concrete meaning in this utility model.
The alignment device of nut of the present utility model is described below with reference to accompanying drawings, as shown in Figure 1, according to embodiment of the present utility model, the cavity 6 that described nut includes nut body 5, is formed in described nut, it is characterized in that, described nut also includes: be formed at the stable steering face 2 of described cavity inner surface, and described stable steering face 2 is positioned at the end of described cavity 6, in order to improve nut fastening after with by the concentricity of securing objects；Screw thread 1, described screw thread 1 is positioned at described cavity 6 inner surface, described nut body 5 one end be through to one end, described stable steering face.
According in this patent background technology to described in prior art, existing nut is that nut screw thread self guides mostly, with by securing objects by screw thread and end face location to realize clamping, but the accuracy error of screw thread itself and being reduced by the chucking power of securing objects and stability by the accuracy error of securing objects end face；And this utility model sets up one section of stable steering face 2 at cavity 6 end within nut body 5, with by coordinating of the surface of securing objects, screw thread 1 deviation can be equilibrated to minimum by stable steering face 2 in nut fastener cycle, improve nut fastening after with by the concentricity of securing objects, meanwhile improve the precision that end face coordinates, increase by the chucking power of securing objects, improve stability, therefore there is clear advantage.
It addition, according to nut disclosed in this utility model also there is following additional technical feature:
According to embodiments more of the present utility model, described nut also includes that stress surface 3, described stress surface 3 are connected with described cavity 6 end, and the axisymmetric position of described stress surface 3 is provided with in order to through by the through hole 4 of securing objects.
According to embodiments more of the present utility model, described nut is circular.
Any mention that " embodiment ", " embodiment ", " illustrative examples " etc. mean to combine concrete component, structure or feature that this embodiment describes and be contained at least one embodiment of the present utility model.In this specification, this schematic representation everywhere is not necessarily referring to identical embodiment.And, when combining any embodiment and describing concrete component, structure or feature, advocated, realize such component, structure or feature in conjunction with other embodiment and all fall within the scope of those skilled in the art.
