Abstract
The utility model discloses a high leakproofness joint Assembly, including connecting the body, cutting ferrule, nut, have endocentric threaded holes and through -hole in the nut, inner diameter of through hole is less than the threaded hole footpath, has round platform shape transitional pore between screw hole and the through -hole, lay a cutting ferrule in the nut in the installation, the cutting ferrule comprises the big rand and the lesser calorie circle that link together, big rand lies in threaded hole, lesser calorie circle tip and transitional pore contact, it is the link with screw hole matched with, link tip and big rand in close contact with to connect body one end. The utility model discloses a with the cutting ferrule setting in the nut for it has good leakproofness between the body and the nut to connect, effectively avoids between the two not hard up, makes combination between them have good leakproofness.
Description
[technical field]
This utility model relates to the technical field of the technical field of pipe fitting, particularly joint.
[background technology]
Parts the most common during adapter assembly, for connecting separate pipe fitting, general joint group
Part uses fittings body to be directly connected to nut, and the pipe fitting combination degree that such connected mode connects is firm not,
Sealing property is not ideal enough, easily produces leakage when hypertonia in pipe fitting, not only affects the normal of equipment
Use, be also easy to cause security incident.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of high leakproofness joint group
Part, it is possible to make adapter assembly be connected firmly, has good sealing.
For achieving the above object, the utility model proposes a kind of high leakproofness adapter assembly, including fittings body,
Cutting ferrule, nut, have concentric screwed hole and through hole in described nut, through hole internal diameter is less than screwed hole internal diameter,
Screwed hole and and through hole between have a truncated cone-shaped transitional pore, lay a cutting ferrule in installing in described nut, card
Set is made up of the big collar linked together and little collar, and described big collar is positioned at screwed hole, little collar end
Portion contacts with transitional pore, described fittings body one end be and corresponding threaded holes close connection end, connect end end with
Big collar is in close contact.
As preferably, described little collar end is arc surface, and transitional pore inwall has circle first elastic packing
Circle, the first elastic seal ring is bonded on transitional pore inwall by glue.
As preferably, described big collar end is embedded with circle second elastic seal ring, has on end end face if connecting
The bulge loop that dry circle is corresponding with the second elastic seal ring.
As preferably, the tip inside of described big collar has a circle auxiliary circle, and auxiliary circle internal diameter is less than in through hole
Footpath.
The beneficial effects of the utility model: this utility model is by being set on card in nut so that joint
Have good sealing between body and nut, be prevented effectively between the two loosen, make both combinations have
Good sealing；Little collar end is that arc surface makes little collar be in close contact with excessive hole, it is ensured that close
Feng Xing；First elastic seal ring and the second elastic seal ring can further improve sealing；Auxiliary circle
The dismounting facilitating cutting ferrule is set.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is the front view of this utility model a kind of high leakproofness adapter assembly.
In figure: 1-nut, 2-cutting ferrule, 3-fittings body, 11-screwed hole, 12-through hole, 13-transitional pore, 14-
The big collar of first elastic seal ring, 21-, the little collar of 22-, 23-the second elastic seal ring, 24-auxiliary circle,
31-connects end, 32-bulge loop.
[detailed description of the invention]
Refering to Fig. 1, this utility model one high leakproofness adapter assembly, including fittings body 3, cutting ferrule 2, spiral shell
Female 1, there are concentric screwed hole 11 and through hole 12 in described nut 1, through hole 12 internal diameter is less than screwed hole 11
Internal diameter, screwed hole 11 and and through hole 12 between have a truncated cone-shaped transitional pore 13, in installing in described nut 1
Laying a cutting ferrule 2, cutting ferrule 2 is made up of the big collar 21 linked together and little collar 22, described kilocalorie
Circle 21 is positioned at screwed hole 11, and little collar 22 end contacts with transitional pore 13, described fittings body 3 one end
For the connection end 31 matched with screwed hole 11, connect end 31 end and be in close contact with big collar 21, described
Little collar 22 end is arc surface, and transitional pore 13 inwall has circle first elastic seal ring 14, the first bullet
Property sealing ring 14 is bonded on transitional pore 13 inwall by glue, and described big collar 21 end is embedded with a circle second
Elastic seal ring 23, connects and has some circles and the corresponding bulge loop of the second elastic seal ring 23 on end 31 end face
32, the tip inside of described big collar 21 has a circle auxiliary circle 24, and auxiliary circle 24 internal diameter is less than in through hole 12
Footpath.
Utility model works process:
Cutting ferrule 2 in the course of the work, is put into nut 1 by this utility model one high leakproofness adapter assembly,
Being screwed on nut 1 by the connection end 31 of fittings body 3, along with turning of fittings body 3, cutting ferrule 2 is constantly to logical
Moving in direction, hole 12, cutting ferrule 2 can occur micro-deformation under external force so that cutting ferrule 2 and excessive hole 13,
Cutting ferrule 2 is in close contact with fittings body 3, and the adapter assembly after connection is connected firmly, and has good sealing,
The setting of first elastic seal ring the 14, second elastic seal ring 23 makes adapter assembly have better seal,
When disassembly is desired, fittings body 3 is back-outed, stretch into one from through hole 12 one end and be slightly less than through hole 12 internal diameter
Pole promotes the auxiliary circle 24 in cutting ferrule 2, can facilitate to separate cutting ferrule 2 with nut 1.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any to this
Scheme after utility model simple transformation belongs to protection domain of the present utility model.
