Abstract
The invention relates to the field of mechanical equipment, in particular to a bolt assembly. The bolt assembly comprises a bolt body integrally formed by a nut and a threaded rod in a connection mode and a gasket. The bolt assembly is characterized in that the threaded rod is formed by a first threaded rod, a second threaded rod and a cylinder coaxially connected with the nut in sequence, a through hole is formed in the gasket, and inner threads corresponding to the outer threads of the first threaded rod are arranged on the inner wall of the through hole. The bolt assembly can achieve a fastening function accurately and stably, avoids the phenomenon of bolt slipping or falling, and is reasonable in structural design and easy to manufacture.
Description
Technical field
The present invention relates to machinery field, relate in particular to a kind of bolt assembly.
Background technique
At present, bolt assembly is widely used in machinery field, and bolt assembly comprises bolt and packing ring conventionally, and bolt and packing ring are fastenedly connected by stamping tool.But existing bolt assembly Chang Yinwei, in order to realize fastening function, causes the wearing and tearing of fastening piece then, can cause for a long time skidding or the generation of obscission, greatly reduce working efficiency, therefore, be necessary to propose a kind of new bolt assembly and solve the problems referred to above.
Summary of the invention
The object of the invention is can accurate stable realize fastening function in order to provide a kind of, also avoided skidding or the generation of obscission, a kind of bolt assembly of simultaneously increasing work efficiency.
To achieve these goals, the present invention can take following technological scheme:
A kind of bolt assembly, it comprises bolt and the packing ring being 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, on described packing ring, offer through hole, described through-hole wall is provided with the internal thread corresponding with described the first threaded stem outside thread.
As the preferred embodiment of the present invention, bolt assembly further comprises that described cylinder is provided with along described cylinder and extends outward the arc-shaped head being connected with described nut.
As the preferred embodiment of the present invention, bolt assembly further comprises that external thread diameter that the diameter of described cylinder is greater than described the second threaded stem is greater than the external thread diameter of described the first threaded stem.
As the preferred embodiment of the present invention, bolt assembly further comprises that the shape of described nut is the square that is provided with four chamferings.
The invention has the beneficial effects as follows: bolt assembly of the present invention, compared with prior art, on packing ring, offer through hole, and through-hole wall is provided with the internal thread corresponding with the first threaded stem outside thread, can realize fastening function, avoid skidding or the generation of obscission, greatly improve working efficiency.Reasonable in design of the present invention, is easy to manufacture.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing relevant of the present invention in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the side view of preferred embodiment of the present invention bolt;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the plan view of preferred embodiment of the present invention packing ring;
Fig. 4 is the plan view of Fig. 3.
Embodiment
Below with reference to each embodiment shown in the drawings, describe the present invention.But these embodiments do not limit the present invention, the conversion in the structure that those of ordinary skill in the art makes according to these embodiments, method or function is all included in protection scope of the present invention.
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, bolt assembly, it comprises bolt 1 and the packing ring 2 being 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, on described packing ring 2, offer through hole 3, 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 being connected with described nut 11, is easy to processing, and attractive in appearance.
Concrete, the external thread diameter that the diameter of described cylinder 123 is greater than described the second threaded stem 122 is greater than the external thread diameter of described the first threaded stem 121, reasonable in design, is easy to processing, and realizing bolt assembly simultaneously, to stablize quick mounting 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 embodiments of the present invention, the assembling of bolt 1 and packing ring 2, can not only realize and 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 not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only illustrating for feasibility mode of execution of the present invention; they are not in order to limit the scope of the invention, all disengaging within equivalent mode of execution that skill spirit of the present invention does or change all should be included in protection scope of the present invention.
