Abstract
The utility model provides a coupling nut for busway shell body, include the nut body and set up at the ascending screw hole of nut body axle that an axial terminal surface of nut body is provided with concave spherical surface's interior concave surface, the edge end portion of interior concave surface is provided with the corner pad towards the outside. The beneficial effects are that can stabilize be connected to the busway shell body on, it is difficult not hard up to screw up the back, corner pad plays the effect of electrically conductive continuity protection and fastening through punctureing the casing patent leather, effectively prevents the nut because electromagnetic induction the electrified contact personnel that shock by electricity with the conductive contact of casing.
Description
Technical field
This utility model belongs to bus duct fastener areas, especially relates to a kind of attaching nut for bus groove case.
Background technology
Bus duct joins power transmission system for low pressure, and the meeting of bus groove case produces alternation leakage field, and metal object meeting induction charging in magnetic field, to contact, personnel cause electric shock；The nut connected on existing bus duct does not have deformation pressuring action, does not have the stop in fastener cycle and the locking effect after fastening, does not have the effect puncturing fastened subject surface coat of paint, and the nut easily loosened causes connection built on the sand.
Utility model content
In view of this; this utility model is directed to a kind of attaching nut for bus groove case; can would be fixedly, stationarily connected on bus groove case; not easily loosen after tightening, concave spherical surface can the elasticity of retaining nut, overall reasonable stress; keep lasting pressure; the effect of conducting continuity protection and fastening, by puncturing housing coat of paint, is played in pad angle, effectively prevents nut because of the charged electric shock exposure personnel of electromagnetic induction with the conductive contact of housing.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
A kind of attaching nut for bus groove case, including nut body and be arranged on described nut body screwed hole axially, one axial end of described nut body is provided with the inner concave of concave spherical, and the marginal end portion of described inner concave is provided with the pad angle towards outside.
Further, described nut body is square nut.
Further, the outer surface of described nut body and described screwed hole is coated with zinc rete.
Relative to prior art, the attaching nut for bus groove case described in the utility model has the advantage that
This utility model can bolt on compact siro spinning technology bus groove case, during connecting bolt, the threaded rod of the screwed hole correspondence extension bolt on nut body, inner concave is towards bolt, after tightening, the pad angle apical grafting of inner concave marginal end portion is on bus groove case, have benefited from the acuteness at pad angle, pad angle can puncture the coat of paint on bus duct shell, pad angle apical grafting is in the coat of paint punctured, it is effectively increased the contact friction force with bus groove case, play stop and prevent the effect loosened, play the effect that would be fixedly, stationarily connected on bus groove case, pad angle is by puncturing housing coat of paint, play the effect of conducting continuity protection and fastening, effectively prevent nut because of the charged electric shock exposure personnel of electromagnetic induction with the conductive contact of housing.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is side-looking structural representation of the present utility model.
Description of reference numerals:
1-nut body；2-screwed hole；3-inner concave；4-pad angle.
Detailed description of the invention
It should be noted that when not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are 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 the device of instruction or 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 is necessary to explanation, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, for instance, it is possible to it is fixing connection, it is also possible to be removably connect, or connect integratedly；Can be mechanically connected, it is also possible to be electrical connection；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, it is possible to be the connection of two element internals.For the ordinary skill in the art, it is possible to understand above-mentioned term concrete meaning in this utility model by concrete condition.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figure 1, 2, this utility model provides a kind of attaching nut for bus groove case, including nut body 1 be arranged on described nut body 1 screwed hole 2 axially, one axial end of described nut body 1 is provided with the inner concave 3 of concave spherical, and the marginal end portion of described inner concave 3 is provided with the pad angle 4 towards outside.
Described nut body 1 is square nut.
The outer surface of described nut body 1 and described screwed hole 2 is coated with zinc rete.
The work process of this example: the threaded rod of the corresponding extension bolt of the screwed hole 2 on nut body 1; inner concave 3 is towards bolt; after tightening; pad angle 4 apical grafting of inner concave 3 marginal end portion is on bus groove case; pad angle 4 punctures the coat of paint on bus duct shell; apical grafting is in the coat of paint punctured; it is effectively increased the contact friction force with bus groove case; play stop and prevent the effect loosened; also function to the effect of conducting continuity protection and fastening, effectively prevent nut because of the charged electric shock exposure personnel of electromagnetic induction with the conductive contact of housing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
