Abstract
The utility model relates to a kind of no gasket downcomer fixture nuts, including hex nut main body, the inside of the hex nut main body is disposed with circular cone clamping section, the bigger diameter end of the circular cone clamping section is connected with inner hole one end of hex nut main body, forms gap between the outside of the circular cone clamping section and the inner hole of hex nut main body.The utility model structure is simple, clamps the inner wall of downcomer by the way that cleverly conus portion is arranged, and eliminates the use of gasket, and will not aging, quick for installation, easy to use, the service life is long, ensure that and use for a long time.
Description
Technical field
The utility model relates to fastener areas, more particularly to a kind of no gasket downcomer fixture nut.
Background technique
It present downcomer and is lauched between hose and needs to be connected with nut, leak is also for preventing from connecting in order to prevent
Loosening generally requires to install a gasket in nut, and gasket does using rubber, for a long time using aging later and hold
It splits, it is ineffective, cause leak.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of no gasket downcomer fixture nuts, and structure is simple,
Clamp the inner wall of downcomer by the way that cleverly conus portion is arranged, eliminate the use of gasket, and will not aging, installation is fast
Victory, easy to use, the service life is long, ensure that and uses for a long time.
The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of fixed spiral shell of no gasket downcomer
Mother, including hex nut main body, the inside of the hex nut main body are disposed with circular cone clamping section, the circular cone clamping section
Bigger diameter end be connected with inner hole one end of hex nut main body, the outside of the circular cone clamping section is interior with hex nut main body
Gap is formed between hole.
Further, the cone angle of the circular cone clamping section is 5-10 °.
Further, the hex nut main body and circular cone clamping section are integrally formed and are made of engineering plastics.
The utility model has the advantages that structure is simple the utility model relates to a kind of no gasket downcomer fixture nut, it is ingenious by being arranged
Conus portion clamp the inner wall of downcomer, eliminate the use of gasket, and will not aging, quick for installation, easy to use, the longevity
Life length ensure that and use for a long time.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figs 1-4, the embodiments of the present invention is related to a kind of no gasket downcomer fixture nut, including hexagonal
Nut main body 1, the inside of the hex nut main body 1 are disposed with circular cone clamping section 2, the major diameter of the circular cone clamping section 2
End is connected with inner hole one end of hex nut main body 1, the outside of the circular cone clamping section 2 and the inner hole of hex nut main body 1
Between formed gap 3.
The cone angle of the circular cone clamping section 2 is 5-10 °.
The hex nut main body 1 and circular cone clamping section 2 are integrally formed and are made of engineering plastics.
When use, downcomer 4 is from top to bottom inserted into nut, and is inserted into and is lauched in hose 5, is lauched hose
5 upper end is inserted into nut from the bottom to top, and is connected by external screw thread with the inner hole internal screw thread of nut, and hex nut master is rotated
Body 1, the upper end for being lauched hose 5 can be gradually inserted into gap 3, and squeeze circular cone clamping section 2, made circular cone clamping section 2 and be lauched
Frictional force between the outer wall of pipe 4 is increasing, and downcomer 4 and the connection for being lauched hose 5 are realized after tightening.
The utility model structure is simple, clamps the inner wall of downcomer by the way that cleverly conus portion is arranged, eliminates gasket
Use, and will not aging, quick for installation, easy to use, the service life is long, ensure that for a long time use.
