Abstract
The utility model relates to a part used for nuclear power, in particular to a captive washer bolt with a hexagon head and a flange face and used for the nuclear power. The captive washer bolt mainly solves the technical problems that after being used for a period of time, an existing screw loosens on a sluice gate, leakage occurs, and safety accidents are caused, and the like. The captive washer bolt comprises a hexagon head (1) and is characterized in that the hexagon head (1) is provided with a flange plate (2), the inner end of the flange plate is connected with a thread rod (4) through a cylindrical section (3), and a spring washer (5) and a flat washer (6) are arranged on the cylindrical section.
Description
Technical field
The utility model relates to a kind of nuclear power component, especially relates to a kind of nuclear power and wears the pad bolt with the hexagon head flange.
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 a kind of nuclear power and wears the pad bolt with the hexagon head flange, 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:
A kind of nuclear power of the present utility model is worn the pad bolt with the hexagon head flange, comprises hexagon head, and described hexagon head the inner is provided with flange plate, and flange plate the inner is connected with threaded stem by cylindrical section, and cylindrical section is provided with compression spring and flat gasket.Hexagon head, flange plate, cylindrical section, threaded stem integral body are made, and whole bolt is made by stainless steel.The total length of hexagon head and flange plate can be 5-6mm, and the overall length of cylindrical section and threaded stem can be 10-14mm.
As preferably, be provided with the arc transition section between described flange plate and the cylindrical section.The arc transition section can the reinforcing flange dish and cylindrical section between intensity.
Therefore, bolt of the present utility model can play fastening effect after use, and the working life of bolt 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;
Accompanying drawing 2 is side structure schematic representation of Fig. 1.
Component, position and numbering among the figure: hexagon head 1, flange plate 2, cylindrical section 3, threaded stem 4, compression spring 5, flat gasket 6, arc transition section 7.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of nuclear power of this example is worn the pad bolt with the hexagon head flange, such as Fig. 1, Fig. 2, comprises hexagon head 1, and hexagon head the inner is provided with flange plate 2, and flange plate the inner is connected with threaded stem 4 by cylindrical section 3, and cylindrical section is provided with compression spring 5 and flat gasket 6.Be provided with arc transition section 7 between flange plate and the cylindrical section.
During use, whole bolt 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. a nuclear power is worn the pad bolt with the hexagon head flange, comprise hexagon head (1), it is characterized in that described hexagon head (1) the inner is provided with flange plate (2), flange plate is inner to be connected with threaded stem (4) by cylindrical section (3), and cylindrical section is provided with compression spring (5) and flat gasket (6).
2. a kind of nuclear power according to claim 1 is worn the pad bolt with the hexagon head flange, it is characterized in that being provided with arc transition section (7) between described flange plate (2) and the cylindrical section (3).
