To better understand the objects, features and advantages of the present invention, with reference to the accompanying drawing and specific real
Applying mode, the present invention is further described in detail.It should be noted that in the absence of conflict, the implementation of the application
Feature in example and embodiment can be combined with each other.
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, still, the present invention may be used also
To be implemented using other than the one described here other modes, therefore, protection scope of the present invention is not by described below
Specific embodiment limitation.
A kind of sealed fitting as shown in Figure 1, general structure include adapter body 1, enter pearl 2 and nut 3.It is using
When, three's coaxial cooperation is first expanding by conduit 4, is inserted in the connecting pin 22 into pearl 2, then connector is inserted into the insertion section 21 for entering pearl 2
Main body 1 finally carries out tightening fixation using 3 sets of nut in the outside for entering pearl 2 and adapter body 1；In adapter body 1 and enter pearl 2
Inside be provided with for fluid circulation runner so that sealed fitting assembling after, fluid can be suitable inside it
It circulates sharply.
In the present embodiment, adapter body 1 includes main body canister portion 13, outer cylindrical portion 11 and inner cylinder portion 12, outer cylindrical portion 11 from
Main body canister portion 13 is coaxially provided projectingly to its axis direction side；Inner cylinder portion 12 be set to the radially inner side of outer cylindrical portion 11 and with
Make jag than outer cylindrical portion 11 jag closer to 13 side of main body canister portion mode and outer cylindrical portion 11 to the same direction from main body
Canister portion 13 is coaxially provided projectingly (i.e. the axial length of outer cylindrical portion 11 or height is longer than the axial length or height of inner cylinder portion 12),
So that forming the first slot of oriented one side opening of axis direction between the inner surface of outer cylindrical portion 11 and the outer surface of inner cylinder portion 12
14.(our inner surfaces and outer surface are defined as follows here: i.e. same position is called interior table close to the surface of shaft core position
Face, the surface far from axle center are called outer surface, throughout the manual and are so defined).Particularly, to the first slot 14
Slot shape has done definitions relevant, and the first slot 14 of setting is from opening to bottom, tapering width, i.e. the first slot 14
Section see substantially become triangle, trapezoidal or other meet the diminishing shape of groove width, such as will be in two of the first slot 14
Surface is set as the curved surfaces of tapering width.In the present embodiment, the first slot 14 specific set-up modes such as Fig. 2 institute
Show.Such setting is easy insertion so that entering the insertion section 21 of pearl 2 very comfortable when being initially inserted into the first slot 14, and
With the increase of insertion depth, the groove width of the first slot 14 is smaller and smaller, cause into the insertion section 21 of pearl 2 and the first slot 14 it
Between pressure it is increasing, further such that the frictional force at this is increasing, to realize the effect that sealing performance is become better and better
Fruit.Simultaneously because the structure setting that the 14 big bottom width of opening width of the first slot is small, so that outer cylindrical portion 11 or inner cylinder portion 12
Thickness close to 1 side of adapter body is thicker, this just can increase structural strength herein, in the long-term use process the part
It is not susceptible to deformation, to accordingly extend the service life of product.For another angle, such structure setting also can
So that acting on the pressure on 14 inner surface of the first slot, a component can be generated on horizontal axis, compared with the prior art side
Enter in case pearl 2 be inserted into when directly to groove portion inner surface effect pressure it is smaller, also can be certain for this angle
Extend the service life of product in degree.
In the present embodiment, entering pearl 2 includes the insertion tubular insertion section 21 of adapter body 1 and separate insertion section 21
Connecting pin 22, insertion section 21 are removably inserted into 14 inside of the first slot to form the first sealing and the second sealing.Here
The first sealing specifically refer to the position that the inner surface of insertion section 21 and outer cylindrical portion 11 contradicts；And the second sealing is specifically
Refer to the position that the outer surface of insertion section 21 and inner cylinder portion 12 contradicts；And enter the connecting pin 22 of pearl 2 in far from diameter on axis direction
It is arranged to protrusion, the fixation after connecting pin 22 is set in convenient for the conduit 4 after expanding keeps its not easy to fall off.
In this embodiment, it is preferred that setting the first cell wall 141 and the second slot for two inner surfaces of the first slot 14
Wall 142, the i.e. inner surface of outer cylindrical portion 11 are set as the first cell wall 141, and the outer surface of inner cylinder portion 12 is set as the second cell wall 142.
And further the tilt angle of the first cell wall 141 and the second cell wall 142 to axial is limited, its tilt angle is limited
It is scheduled between 0.5 ° -5 °.Here the restriction of tilt angle is to have done what a large amount of different experiments obtained according to different actual conditions
Optimal range of tilt angles.If tilt angle is too small, then horizontal axis component is too small, the effect for the reduction pressure that can be played
It is very weak, it can be ignored；If tilt angle is excessive, insertion section 21 is not easy to be seated in the first slot 14 again, is easy to loosen.
Again since outer cylindrical portion 11 and inner cylinder portion 12 have different thickness, for considering 12 integral thickness of inner cylinder portion compared with outer cylindrical portion 11
Thinner situation, therefore tilt angle of the tilt angle less than the second cell wall 142 of the first cell wall 141 is set.It is such to set
Setting is advantageous in that: in the case where generating uniform pressure to inner cylinder portion 12, the tilt angle of the second cell wall 142 is bigger, then diameter
Upward component is relatively smaller, while increasing inner cylinder portion 12 close to the thickness of 1 one end of adapter body, therefore when entering pearl 2 and being inserted into
The structural strength that may further ensure that Insert Here structure increases the service life of product.In order to easily facilitate into pearl 2
Insertion section 21 insertion, be additionally provided with chamfering 121, i.e. chamfering in the opening of corresponding first cell wall 141 of the second cell wall 142
121 are set to the inner surface side of inner cylinder portion 12 and separate 1 one end of adapter body, and the setting of chamfering 121 herein enters pearl 2 for convenience
Insertion section 21 be inserted into the first slot 14, so in the present solution, the opening of corresponding first slot 14 of the second cell wall 142 is to set
Two sections of inclined structures of difference are equipped with, each section of functions and effects are not also identical.
As shown in Figure 3 is the specific structure signal of the insertion section 21 into pearl 2.Structurally, insertion section 21 and entering pearl 2
The second slot 23 to cooperate inner cylinder portion 12 is circumferentially formed between inner wall, i.e. the second slot 23 is formed in 21 thickness side of insertion section
Upwards.The inner surface of second slot 23 is denoted as third cell wall 231, the outer surface of the second slot 23 is denoted as the 4th cell wall 232,
Third sealing is formed between third cell wall 231 and inner cylinder portion 12.The setting of third sealing increases seal nipple sealing
Quantity can pass through when the first sealing or the second sealing fail that is, produce multi-sealed effect
Spare third sealing, can play certain sealing effect, extend the service life of sealed fitting, improve sealing
The service life of pipe fitting.It is as shown in Figure 4 and Figure 5 to enter specific connection structure signal of the pearl 2 when being inserted into adapter body 1.
In the present embodiment, further the second slot 23 is limited, by the second slot 23 from opening to bottom,
It is arranged to the structure of tapering width, so as to the insertion of inner cylinder portion 12, while also can increases by the with the increase of insertion depth
The sealing effect of three sealings further can also improve structural strength herein to a certain extent.It is being embodied
During, third cell wall 231 and the 4th cell wall 232 are disposed as inclined-plane, and the tilt angle setting of third cell wall 231
Greater than the tilt angle of the 4th cell wall 232, the angle opening formed between third cell wall 231 and the 4th cell wall 232 is about
Between 15 ° -55 °.Due to the width of insertion section 21 can be slightly larger than or equal to the first slot 14 width, so enter pearl 2 be inserted into
During first slot 14, an extruding can be generated to the first slot 14, so that it is generated flaring deformation or generated flaring deformation
Trend, and the angle degree of such range is formed between third cell wall 231 and the 4th cell wall 232, no matter the first slot 14 expands
The deformation of mouth is big or small, and inner cylinder portion 12 can be allowed to be inserted into inside the second slot 23.And passes through the effect of the second slot 23, reduce
The deformation tendency of first slot 14, increases the structural strength at this.It is interior during inner cylinder portion 12 is inserted into the second slot 23
The depth that canister portion 12 is inserted into is at least 0.8 times of 23 total depth of the second slot.The restriction of this 12 insertion depth of inner cylinder portion, can
Guarantee the structural strength of third sealing and the state that sealing effect is optimal.If the depth that inner cylinder portion 12 is inserted into is less than the
0.8 times of two slots, 23 total depth, then the sealing effect of third sealing cannot be guaranteed, simultaneously because excessive is not inserted into sky
Between, it can also make the structural strength decrease to some degree at this.
The advantages of capable of bringing in order to illustrate the first slot 14 according to the structure setting in this programme, we have done relevant
It is verified, therefore has made four groups of samples, A group: including adapter body 1, enter pearl 2, nut 3,141 He of the first cell wall
Second cell wall 142 is disposed as inclined-plane；B group: including adapter body 1, enter pearl 2, nut 3, the first cell wall 141 is set as oblique
Face, and the second cell wall 142 is set as and axial parallel plane；C group: including adapter body 1, enter pearl 2, nut 3, the first slot
Wall 141 is set as the plane parallel with axial direction, and the second cell wall 142 is set as inclined-plane；D group: including adapter body 1, enter pearl 2,
Nut 3, the first cell wall 141 and the second cell wall 142 are disposed as and axial parallel plane (i.e. prior art products).In order to

It by upper table one and table two, can clearly draw a conclusion, whether be under which kind of operating condition, when the first slot 14
First cell wall 141, the second cell wall 142 any one when being set as inclined-plane, the sealing effect of product is superior to prior art
(i.e. the sample d1-d5 of D group)；When the first cell wall 141 of the first slot 14, the second cell wall 142 are disposed as inclined-plane, sealing
Performance is again more much better than the leakproofness that the first cell wall 141 or the single surface of the second cell wall 142 are set as inclined-plane.Therefore comprehensive real
Test conclusion, it is believed that have certain inclined groove portion structure compared to for traditional structure, sealing effect and service life have one
Determine the raising in degree.
In the present embodiment, the one side that inner cylinder portion 12 and third cell wall 231 contradict, is also configured as inclined surface, and it inclines
Rake angle is greater than the tilt angle of third cell wall 231, and the purpose being arranged in this way is the sealing being further ensured that at third sealing
