Abstract
The utility model relates to a part for nuclear power, in particular to an internal-hexagon-pyramid-end set screw special for the nuclear power. The set screw mainly solves the technical problems that after being used for a period of time, an exiting screw loosens on a sluice gate, leakage occurs and thereby safety accidents are caused, and the like. The set screw comprises a screw body (1) and is characterized in that the end face of one end of the screw body (1) is provided with an internal hexagon cavity (2), the other end of the screw body is provided with a cone section (3), and the outer end face of the cone section is a plane (4).
Description
Technical field
The utility model relates to the component that a kind of nuclear power is used, and especially relates to hexagonal cone end Cock 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 some fixes size and structure in the sluice gate, if fixed effect is bad, then 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 groove and are formed by plane and plane combination with the center line oblique of this screw that a center line with screw coincides respectively, the angle on this two plane less than 90 degree greater than 60 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 be loosening at sluice gate, leaks thereby produce, and then can cause security incident.
The model utility content
The utility model provides hexagonal cone end Cock screw in a kind of nuclear power special use, and it mainly is to solve the existing screw of prior art after using one section, and screw can be loosening at sluice gate, leaks thereby produce, 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 cone end Cock screw comprises screw body in a kind of nuclear power special use of the present utility model, and an end end face of described screw body is provided with interior hexagonal cavity, and the other end of screw body is provided with conical section, and the exterior edge face of conical section is the plane.Whole Cock screw is made by stainless steel.The length of Cock screw can be 8-10mm, and the taper angle of the conical section conical surface can be 45 o or 30o.
As preferably, an end end face of described screw body is provided with chamfering.Chamfering can be 45 o or 30o chamfering.
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 among the figure: screw body 1, interior hexagonal cavity 2, conical section 3, plane 4, chamfering 5.
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 cone end Cock screw in a kind of nuclear power special use of this example, such as Fig. 1, Fig. 2, comprise screw body 1, an end end face of screw body is provided with interior hexagonal cavity 2, and the other end of screw body is provided with conical section 3, and the exterior edge face of conical section is plane 4.One end end face of screw body is provided with chamfering 5.
During use, whole Cock screw is screwed on the sluice gate that nuclear power uses gets final product.
The above only is 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 claim of the present utility model.
Claims (2)
1. the interior hexagonal cone of nuclear power special use is held Cock screw, comprise screw body (1), an end end face that it is characterized in that described screw body (1) is provided with interior hexagonal cavity (2), and the other end of screw body is provided with conical section (3), and the exterior edge face of conical section is plane (4).
2. hexagonal cone end Cock screw in a kind of nuclear power special use according to claim 1 is characterized in that an end end face of described screw body (1) is provided with chamfering (5).
