Abstract
The utility model relates to a part for nuclear power, in particular to a special inner hexagonal hexagon-head screw for nuclear power. The utility model mainly solves the technical problem that in the prior art, after being used for a certain time, a screw can be loosened on a sluice gate so as to generate leakage which can cause a safety accident and the like. The special inner hexagonal hexagon-head screw for nuclear power comprises a bolt body (1) and is characterized in that the bolt body (1) is cylindrical; one end of the bolt body is provided with a hexagon head (2); and the outer end face of the hexagon head is provided with an inner hexagonal cavity (3).
Description
Technical field
The utility model relates to the component that a kind of nuclear power is used, and especially relates to hexagonal hex head screw in a kind of nuclear power special use.
Background technique
Existing more product all needs to use screw in process of production, particularly in the field of nuclear power gate, screw need to be filled out that in sluice gate, some fixes size and structure, if fixed effect is bad, can cause more sluice gate to be revealed, waste great lot of water resources, even caused security incident.Chinese patent discloses a kind of Polycylinder combination head tapping screw (notice of authorization number: CN201810640U), there is a self tapping flute its termination at screw thread, the head that it is characterized in that screw is combined by the identical part cylinder along garden Zhou Junbu of a plurality of radiuses, at this head, part cylindrical section quantity identical a plurality of the screw grooves identical with a plurality of radiuses are arranged, this head a plurality of screw the groove center line with screw coincides by one respectively plane and the plane combination with the center line oblique of this screw and form, the angle on this two plane is spent greater than 60 less than 90 degree, with the center line oblique plane of this screw oblique be that center from the polycylindser combination head tilts to export-oriented thread section direction.Chinese patent also discloses a kind of automatic locking screw (notice of authorization number: CN201810632U), it is followed successively by from top to bottom and is provided with externally threaded screw head, screw rod and nut, it is characterized in that: screw rod is the hollow screw bar, and hollow screw bar both sides are respectively equipped with slotted hole, the width of slotted hole is less than the internal diameter of hollow screw bar, in the inner chamber of hollow screw bar, spring is set, the spring upper end is provided with plug, the both wings of plug stretch out outside the hollow screw bar by slotted hole, spring is not less than the length of hollow screw bar under free extended configuration, the distance of the both wings of plug is greater than the diameter of nut.But these two kinds of screws are after using one section, and screw can become flexible on sluice gate, leak thereby produce, and then can cause security incident.
The model utility content
The utility model is to provide hexagonal hex head screw in a kind of nuclear power special use, and it is mainly to solve the existing screw of prior art after using one section, and screw can become flexible on sluice gate, thereby produces leakage, and then can cause the technical problem of security incident etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Hexagonal hex head screw in a kind of nuclear power special use of the present utility model comprises bolt body, and described bolt body is cylindrical, and the one end is provided with hexagon head, and the hexagon head exterior edge face is provided with an interior hexagonal cavity.Hexagon head, bolt body integral body are made, and whole bolt is made by stainless steel.The length of hexagon head can be 7-8mm, and the overall length of bolt body can be 22-27mm.
As preferably, be provided with the arc transition section between described hexagon head and bolt body.The arc transition section can be strengthened the intensity between hexagon head and bolt body.
Therefore, screw of the present utility model can play the effect of location after use, and the working life of screw is longer, thereby can avoid causing security incident, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Component, position and numbering in figure: bolt body 1, hexagon head 2, interior hexagonal cavity 3, arc transition section 4.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: hexagonal hex head screw in a kind of nuclear power special use of this example, as Fig. 1, Fig. 2, comprise bolt body 1, bolt body is cylindrical, and the one end is provided with hexagon head 2, and the hexagon head exterior edge face is provided with an interior hexagonal cavity 3.Be provided with arc transition section 4 between hexagon head and bolt body.
During use, whole screw is screwed on the sluice gate that nuclear power uses gets final product.
The above is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the scope of the claims of the present utility model.
