Abstract
The utility model discloses a sealing bolt. A circle of groove is arranged on a pressing face of the bolt body, and a sealing ring is embedded in the groove. The utility model further discloses a sealing nut. A circle of groove is arranged at one end of a pressing face of the nut body, a sealing ring is embedded in the groove, and the other end of the nut body is equipped with a blind cover. The sealing bolt and the sealing nut guarantee sealing of a connecting portion when fixing base materials, completely resolve the problem that the pressing face and the thread portion of the existing bolt are not sealed, and has wide usage.
Description
Technical field
The utility model belongs to technical field of sealing technology, relates to a kind of sealing bolt, also relates to a kind of sealing nut.
Background technique
Existing bolt and nut belong to standard piece, specification is more, though what can guarantee to connect is firm, but when directly connecting body material with bolt and nut, bolt hole for body material does not have reliable seal approach, reveals thereby produce, and causes the bolt joint can not satisfy the technical requirements of sealing, even use various pads to improve sealing effect, but effect still is not ideal enough.
Summary of the invention
The purpose of this utility model provides a kind of sealing bolt, has solved the packing less problem of existing bolt seal face and screw thread place.
Another purpose of the present utility model provides the sealing nut that a kind of and above-mentioned bolt matching uses, and has solved the packing less problem of existing nut seal face and screw thread place.
The technological scheme that the utility model adopted is that a kind of sealing bolt comprises the body of bolt, has a circle raceway groove on the seal face of the body of bolt, is inlaid with seal ring in raceway groove.
Another technological scheme that the utility model adopted is, a kind of sealing nut comprises nut body, has a circle raceway groove on seal face one end of nut body, is inlaid with seal ring in raceway groove, is provided with blind lid at the other end of nut body.
The beneficial effects of the utility model are, separately or be used sealing bolt of the present utility model and sealing nut, can guarantee the sealing at bolt seal face and screw thread place, satisfy the requirement that is tightly connected.
Description of drawings
Fig. 1 is a sealing bolt example structure schematic representation of the present utility model;
Fig. 2 is a sealing nut example structure schematic representation of the present utility model.
Among the figure, the 1. body of bolt, 2. seal ring, 3. raceway groove, 4. sealing surface, 5. flank of thread, 6. nut body, 7. blind lid, 8. seal face.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, sealing bolt example structure of the present utility model is, around the body of bolt 1 axis one circle raceway groove 3 is set in the bottom part ring of the seal face 8 of the body of bolt 1, and the bottom length of raceway groove 3 is inlaid with seal ring 2 greater than the opening size of raceway groove in raceway groove 3.Flank of thread 5 is according to the specification setting of the body of bolt 1.
As Fig. 2, sealing nut example structure of the present utility model is, has the raceway groove 3 of a circle and flank of thread 5 concentrics on seal face 8 one ends of nut body 6, is inlaid with seal ring 2 in raceway groove 3, the other end at nut body 6 is provided with blind lid 7, also is used for the sealing of flank of thread 5.
As Fig. 1, Fig. 2, after tightening sealing bolt of the present utility model and sealing nut, the sealing surface 4 of seal ring 2 is fitted closely with substrate material surface on the body of bolt 1 or the nut body 6, realizes the effect of sealing.Seal ring 2 is embedded in the raceway groove 3, is not easy, and has guaranteed the abundant applying of the body of bolt 1 or nut body 6 seal faces 8 and substrate material surface when compressing.
Sealing bolt of the present utility model and sealing nut to body material fixedly the time guaranteed the sealing of connection part thoroughly to have solved the packing less problem of existing bolt seal face and screw thread place, have wide purposes.
