Description
Technical field
This utility model relates to a kind of hexagon socket head cap screw, belongs to machanical fastener technical field.
Background technology
Bolt-connection has substantial amounts of application in industries such as automobile, machinery, buildings, is a kind of important connecting mode.Bolt is securing member conventional in frame for movement and building element, bolt is in most of the cases processed according to national standard or industry standard manufacture, the bolt multidigit standard component used in the bolt sold on market and machinery industry, bolt of a great variety, but in most cases distinguish according to screw diameter and bolt head shape, screw flight can be divided into coarse thread, fine thread, inch screw thread and nonstandard screw thread, so just having the mode calling bolt according to thread forms, such as bolt of serration, coarse thread bolt；Square head bolt, dormant bolt, hex bolts, snap bolt, button-headed bolt, T bolt etc. can be divided into again according to the difference of the shape of nuts.Hex bolts is divided into hexagon socket head cap screw and outer-hexagonal bolt, and hexagon socket head cap screw nuts is round end, and hexagon counterbore is offered at round end center, outer-hexagonal threaded screw fasteners cap be shaped as regular hexagon.
Existing hexagon socket head cap screw in use due in frock lubricating oil and dust be mixed into or internally colliding with of hexagonal bolt head causes hexagon socket head cap screw hole block or damage deformation, make to cause difficulty to staff in dismounting, in-convenience in use, lose time.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of hexagon socket head cap screw.
This utility model is a kind of hexagon socket head cap screw with protection lid; it comprises protection lid, connects band, nuts, packing ring, external threaded, inner hexagonal hole, outer-hexagonal stopple; the lower surface of nuts connects the upper surface of external threaded; the upper surface of nuts offers inner hexagonal hole; one end of protection lid is fixed on nuts by outer-hexagonal stopple; protection lid is connected with packing ring by connecting band, and packing ring is arranged on the position, lower surface of nuts by screw rod.
As preferably, described nuts 3 being provided with anti-skidding annular knurl stricture of vagina.
As preferably, the upper end of described protection lid 1 is circular arc head.
As preferably, described protection lid 1 being provided with dismounting groove.
The beneficial effects of the utility model are: realize the protection of hexagon socket head cap screw, consolidate and attractive in appearance, easy and simple to handle, easy to use.

Detailed description of the invention:
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, this utility model is described.However, it should be understood that these descriptions are illustrative of, and it is not intended to limit scope of the present utility model.Additionally, in the following description, eliminate the description to known features and technology, to avoid unnecessarily obscuring concept of the present utility model.
As Figure 1-3; originally novel detailed description of the invention is by the following technical solutions: it comprises protection lid 1, connects band 2, nuts 3, packing ring 4, external threaded 5, inner hexagonal hole 6, outer-hexagonal stopple 7; the lower surface of nuts 3 connects the upper surface of external threaded 5; the upper surface of nuts 3 offers inner hexagonal hole 6; one end of protection lid 1 is fixed on nuts 3 by outer-hexagonal stopple 7; protection lid 1 is with 2 to be connected with packing ring 4 by connecting, and packing ring 4 is arranged on the position, lower surface of nuts 3 by external threaded 5.
Further, described nuts 3 is provided with anti-skidding annular knurl stricture of vagina.
Further, the upper end of described protection lid 1 is circular arc head
Further, described protection lid 1 is provided with dismounting groove.
The operation principle of this novel detailed description of the invention is: hexagon socket head cap screw raises protection lid 1 in use; tight a bolt with track wrench; it is relatively reliable that packing ring 4 can guarantee that bolt is fixed; bolt covers protection lid 1 by the inner hexagonal hole 6 on outer-hexagonal stopple 7 and nuts 3 after tightening; not only play the effect of protection bolt but also bolt can be made fixing more firm; can also bolt profile attractive in appearance, easy and simple to handle, easy to use.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
