Abstract
The utility model relates to the field of mechanical equipment, in particular to a bolt component, which comprises a bolt and a washer, wherein the bolt and the washer are integrally connected by a nut and a screw; the bolt component is characterized in that the screw consists of a first threaded rod, a second threaded rod and a cylinder in sequence; the cylinder is coaxially connected with the nut; the washer is provided with a through hole; and the inner wall of the through hole is provided with internal threads corresponding to external threads of the first threaded rod. According to the bolt component, a fastening function can be accurately and stably realized, and the phenomenon of skidding or falling of the bolt is avoided; and the bolt component has rational structural design and is easy to manufacture.
Description
Technical field
The utility model relates to the machinery field, relates in particular to a kind of bolt assembly.
Background technique
At present, bolt assembly is widely used in the machinery field, and bolt assembly comprises bolt and packing ring usually, and bolt and packing ring are fastenedly connected by stamping tool.But existing bolt assembly Chang Yinwei causes the wearing and tearing of fastening piece then in order to realize fastening function, can cause for a long time skidding or the generation of obscission, greatly reduces working efficiency, therefore, is necessary to propose a kind of new bolt assembly and solves the problems referred to above.
The model utility content
The purpose of this utility model is can accurate stable to realize fastening function in order to provide a kind of, has also avoided skidding or the generation of obscission a kind of bolt assembly of increasing work efficiency simultaneously.
To achieve these goals, the utility model can be taked following technological scheme:
A kind of bolt assembly, it comprises bolt and the packing ring that is connected to form by nut and screw rod one, it is characterized in that, described screw rod is comprised of the first threaded stem, the second threaded stem, the cylinder that is connected with described nut coaxial line successively, offer through hole on the described packing ring, described through-hole wall is provided with the internal thread corresponding with described the first threaded stem outside thread.
As preferred implementation of the present utility model, bolt assembly comprises further that described cylinder is provided with along described cylinder and extends outward the arc-shaped head that is connected with described nut.
As preferred implementation of the present utility model, the diameter that bolt assembly further comprises described cylinder is greater than the external thread diameter of described the second threaded stem external thread diameter greater than described the first threaded stem.
As preferred implementation of the present utility model, bolt assembly comprises that further the shape of described nut is the square that is provided with four chamferings.
The beneficial effects of the utility model are: bolt assembly of the present utility model, compared with prior art, offer through hole on the packing ring, and through-hole wall is provided with the internal thread corresponding with the first threaded stem outside thread, can realize fastening function, avoided skidding or the generation of obscission, greatly improved working efficiency.The utility model reasonable in design is easy to make.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the side view of the utility model preferred embodiment bolt;

Fig. 3 is the plan view of the utility model preferred embodiment packing ring;
Fig. 4 is the plan view of Fig. 3.
Embodiment
Below with reference to each embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.
With reference to Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, bolt assembly, it comprises bolt 1 and the packing ring 2 that is connected to form by nut 11 and screw rod 12 one, described screw rod 12 is comprised of the first threaded stem 121, the second threaded stem 122, the cylinder 123 that is connected with described nut 11 coaxial lines successively, offer through hole 3 on the described packing ring 2, described through hole 3 inwalls are provided with the internal thread corresponding with described the first threaded stem outside thread.
Wherein, described cylinder 123 is provided with along described cylinder 123 and extends outward the arc-shaped head 4 that is connected with described nut 11, is easy to processing, and attractive in appearance.
Concrete, the diameter of described cylinder 123 is greater than the external thread diameter of described the second threaded stem 122 external thread diameter greater than described the first threaded stem 121, and is reasonable in design, is easy to processing, can realize that bolt assembly is stablized quick mounting simultaneously fastening.
Concrete, the shape of described nut 11 is the squares that are provided with four chamferings, is easy to processing, and attractive in appearance.
In the preferred embodiment of the present utility model, the assembling of bolt 1 and packing ring 2 can not only realize being fastenedly connected, and has avoided skidding or the generation of obscission, has improved working efficiency.
Be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility mode of execution of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
