On, connecting tube pipe periphery is waled using obturating cup in the prior art and carries out necessary processing, considers sealing effect, above-mentioned obturating cup
On the aperture that is equipped with it is generally more slightly less than connecting tube, i.e., installed by the way of interference fit, this interference fit
Mode, although ensure that the sealing function of obturating cup, during practice, connecting tube is accordingly led to penetrating obturating cup
Extremely difficult when hole, the phenomenon that operating personnel's palm is worn, happens occasionally, and working efficiency is extremely low.
Utility model content
Therefore, the technical problem to be solved by the present invention is to provide a kind of obturating cup and air conditioners, can ensure
While leakproofness, the assembly difficulty of connecting tube and obturating cup is substantially reduced, improves working efficiency.
To solve the above-mentioned problems, the utility model provides a kind of obturating cup, including bowl body, bowl body bottom surface open up assembly
Hole, the pilot hole inner wall are equipped with the first cooperation section, the second cooperation section in an axial direction, and the first cooperation section is interference fit section,
The second cooperation section is that clearance fit section and/or transition coordinate section.
Further, the first cooperation section is axially arranged alternately with the second cooperation section along the pilot hole.
Further, the first cooperation section is arranged close to the pilot hole upper surface.
Further, the interference fit section includes interference rib.
Further, the section of the interference rib be, rectangle, trapezoidal, arc-shaped or triangle.
Further, the bowl body bottom is equipped with seal boss, and the pilot hole is axially through the seal boss.
Further, the upper surface of the seal boss is equipped with drainage inclined-plane.
Further, the low conical surface of high surrounding centered on the drainage inclined-plane.
Further, the seal boss is multiple, and each pilot hole aperture is identical or different.
The utility model also provides a kind of air conditioner, including connecting tube, the connecting tube and any technology of the utility model
The pilot hole of obturating cup described in scheme is set with one heart.
Obturating cup provided by the utility model, since its pilot hole includes the first cooperation section and the second cooperation section, first matches

Specific implementation mode
For ease of the description of structure and application method to the utility model, present embodiment is with obturating cup practical application feelings
Bearing definition under condition is upper and lower.
As shown in Fig. 1~2, the embodiments of the present invention provide a kind of obturating cup, including bowl body 1, bowl body bottom surface open up
Pilot hole 21, pilot hole 21 is for installing connecting tube, to solve the technical issues of the utility model is proposed, 21 inner wall of pilot hole
It is equipped with the first cooperation section 22, second in an axial direction and coordinates section 23, the first cooperation section 22 is interference fit section, between the second cooperation section 23 is
Gap coordinates section and/or transition coordinates section, and the first cooperation section 22 is axially arranged alternately with the second cooperation section 23 along pilot hole 21, such
Set-up mode makes connecting tube to be installed and the contact area of 21 inner wall of pilot hole significantly reduce, so reduce connecting tube with it is close
The assembly frictional force between bowl is sealed, keeps installment work more smooth.
In said program, the condensed water outside connecting tube goes out at the gap that connecting tube is engaged with pilot hole 21 in order to prevent
The first cooperation section 22 can be arranged close to 21 upper surface of pilot hole the phenomenon that being now detained.
In said program, interference rib 24 can be used in interference fit section, and the section of interference rib 24 can select rectangle, ladder
Any one of shape, arc-shaped, triangle, wherein arc-shaped and triangular-section interference rib 24 due to connecting tube
Direct contact surface is line contact, compares the interference rib 24 of rectangle or trapezoid cross section and contact surface is more the case where connecting tube face contacts
It is small, therefore for reducing the frictional force of installation connecting tube advantageously.
In order to increase the combination length of connecting tube and pilot hole 21, and then ensure that the connection of connecting tube and obturating cup is reliable
It spends, seal boss 2 is set in bowl body bottom surface in said program, seal boss 2 is fixedly connected with the bottom surface of bowl body 1, pilot hole 21
Axially through seal boss 2.
Further, condensed water is detained for a long time in the upper surface of seal boss 2 in order to prevent, and the utility model is close
The upper surface of envelope boss 2, which is equipped with, drains inclined-plane 25, and the low conical surface of high surrounding, draws when condensing drip is fallen on centered on drainage inclined-plane 25
It will take advantage of a situation and flow down when on stream inclined-plane 25, and thus greatly reduce condensed water and be trapped in the fitting surface of connecting tube and seal boss 2 simultaneously
The possibility of infiltration.
One obturating cup may need to carry out assembly connection with more connecting tubes simultaneously, and more connecting tube calibers may be identical
May also be different, therefore, the seal boss in above-mentioned technical proposal can be arranged it is multiple, particular number depending on operating mode is installed,
Each assembly aperture is identical or different.
Rubber material can be used in bowl body 1, seal boss 2 described in above-mentioned technical proposal.
To absolutely prove that the function of the utility model is realized, it is described below in conjunction with specific example.As shown in figure 3, false
The fixed a diameter of D1 of connecting tube to be assembled, obturating cup pilot hole first coordinate section a diameter of D2, the second cooperation a diameter of D3 of section, then
The relationship that should have is D3 >=D1 ＞ D2, and D2, D3 replace in an axial direction in 21 inner wall of pilot hole, specifically, working as D1=6mm
When, it all can cause to rub for 5.6mm to realize that preferable sealing effect, preferably D2=5.6mm, but full section interference fit are diameter
Power is very big, and poling is extremely difficult, and uses the obturating cup of the utility model, the first cooperation section diameter D2=5.6mm, i.e. D2 ＜
6mm, second cooperation section diameter D3 >=6mm, such obturating cup greatly reduce connecting tube and the contact area of obturating cup, are ensureing
The frictional force between connecting tube and seal boss is reduced while interference fit, therefore can substantially reduce poling difficulty, is carried
High working efficiency, and can guarantee the leakproofness of obturating cup.
The embodiments of the present invention also provide a kind of air conditioner, including any technical solution of the utility model provide it is close
Seal bowl.Air conditioner includes connecting tube, connecting tube and the concentric suit of pilot hole 21 on obturating cup, so that obturating cup is fixed on company
It takes over.
Those skilled in the art will readily recognize that under the premise of not conflicting, above-mentioned each advantageous manner can be free
Ground combination, superposition.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle
Within the scope of shield.Above are merely preferred embodiments of the utility model, it is noted that for the ordinary skill of the art
For personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with modification.
