Fig. 2 is structural schematic diagram when cutting ferrule nut is not tightened；
Fig. 3 is structural schematic diagram when cutting ferrule nut is tightened；
It is as shown in the figure:
Wherein, 1- Steel Tube Special, 2- cutting ferrule nut, 3- cutting ferrule, 4- fixed ring, 5- elastic sealed body, 6- fitting body.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
The technical solution of the utility model embodiment is clearly and completely described in the attached drawing of type embodiment.Obviously, described
Embodiment is a part of the embodiment of the utility model, instead of all the embodiments.Based on described the utility model
Embodiment, those of ordinary skill in the art's every other embodiment obtained under the premise of being not necessarily to creative work, all belongs to
In the range of the utility model protection.
Unless otherwise defined, the technical term or scientific term that the disclosure uses should be tool in disclosure fields
The ordinary meaning for thering is the personage of general technical ability to be understood.The similar word meaning such as " comprising " or "comprising" used in the disclosure
Point out that element or object before the existing word are covered the element for appearing in the word presented hereinafter or object and its be equal, without
Exclude other elements or object."upper", "lower", "left", "right" etc. are only used for indicating relative positional relationship, when being described object
Absolute position change after, then the relative positional relationship may also correspondingly change.
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 3, a kind of elastic packing cutting ferrule, including Steel Tube Special 1, cutting ferrule nut 2, cutting ferrule 3, fitting body
6, the cutting ferrule nut 2 and the cutting ferrule 3 are socketed on the Steel Tube Special 1, and the cutting ferrule nut 2 is connected to the fitting body
On 6, the cutting ferrule 3 is installed between the fitting body 6 and the cutting ferrule nut 2, and the fitting body has inner conical surface；The card
Fixed ring 4 is equipped between set 3 and the fitting body 6, the fixed ring 4 is socketed on Steel Tube Special 1, and the fixed ring 4 is close
The conical surface of 6 one end of fitting body is equipped with elastic sealed body 5, and the elastic sealed body 5 is socketed on the Steel Tube Special 1, described
Elastic sealed body 5 has the male cone (strobilus masculinus) matched with 6 inner conical surface of fitting body.
The elastic sealed body 5 is socketed on the Steel Tube Special 1, and 5 internal diameter of elastic sealed body is less than outside Steel Tube Special 1
Diameter, 5 male cone (strobilus masculinus) size of elastic sealed body are greater than 6 inner conical surface size of fitting body, can thus make 5 inner hole wall of elastic sealed body tight
Tightly hold outer surface of steel tube tightly, 5 male cone (strobilus masculinus) of elastic sealed body fits tightly on together with 6 inner conical surface of fitting body, the elasticity
Seal 5 vulcanizes in fixed ring 4, and elastic sealed body is made of corrosion-resistant, high-low temperature resistant, high voltage bearing silastic material.
Elastic sealed body 5 plays sealing gas, and cutting ferrule 3 are played holding steel pipe, and conventional rigid hermetic collar is then
Play two kinds of steel pipe of sealing and holding；Connector inner conical surface can be damaged when the damage of rigid seal cutting ferrule, and works as the utility model
Elastic sealed body and when fixed ring, replaceable elastic sealed body and fixed ring assembly, elastic packing cutting ferrule do not damage in connector
The conical surface；
When cutting ferrule nut 2 is tightened, cutting ferrule nut 2 moves to the left, drives cutting ferrule 3 to move downward, cutting ferrule 3 is in fixed ring
4 and cutting ferrule nut 2 under the action of, 3 front end of cutting ferrule generates the deformation of a radial direction, which will lead to Steel Tube Special 1 in cutting ferrule 3
Front end generates a protrusion, while cutting ferrule 3 can inwardly cut Steel Tube Special 1.Cutting ferrule 3 plays promptly Steel Tube Special, prevents
Steel Tube Special falls off.Because 5 internal diameter of elastic sealed body is slightly less than Steel Tube Special 1, while 5 male cone (strobilus masculinus) size of elastic sealed body is omited
Greater than 6 inner conical surface size of fitting body.When cutting ferrule 3 moves downward, fixed ring 4 and elastic sealed body 5 can also moved downward together
(this move distance very little).5 inner wall of elastic sealed body can be thus made tightly to hold outer surface of steel tube, elastic sealed body 5 tightly
Male cone (strobilus masculinus) fits tightly on together with 6 inner conical surface of fitting body, while under internal pressure effect, elastic sealed body 5 can be to axis
Generate a pressure to radial so that elastic sealed body 5 more tightly with 6 inner cone of 1 outer surface of Steel Tube Special and fitting body
Face contact together, has played enhancing sealing.Elastic sealed body 5 and Steel Tube Special 1 and fitting body 6 are formd like this
Two seals.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation be not intended to limit the utility model although the utility model has been disclosed with preferred embodiment as above, it is any ripe
Professional and technical personnel is known, is not being departed within the scope of technical solutions of the utility model, when in the technology using the disclosure above
Hold the equivalent embodiment made a little change or be modified to equivalent variations, but all without departing from technical solutions of the utility model
Hold, any simple modification, equivalent change and modification made by the above technical examples according to the technical essence of the present invention, still
