Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
As shown in Figure 1, 2, in the nonadiabatic reducing first embodiment of the punched of the utility model, which includes the
One tube body 2, the second tube body 3 and the conical pipe 4 for being connected to first tube body 2 and the second tube body 3, the diameter of first tube body 2 are small
In the diameter of second tube body 3, which is connected to the conical pipe 4,3 first end of the second tube body and the cone
Shape pipe 4 is connected to, which is equipped with the first connecting portion 10 for being tightly connected other tube bodies, first connection
Portion 10 includes being sheathed on the first annular sealing ring 5 of 2 first end of the first tube body and by the 2 first end end of the first tube body
The first annular installation position 6 for fixing the first annular sealing ring 5 that outside crimping is formed.
When reducing 1 nonadiabatic using the punched of the utility model, 2 first end of the first tube body progress backrush crimping is formed
Then first annular sealing ring 5 is inserted into first annular installation position 6 and is fixed by first annular installation position 6, with other
When tube body is attached, first annular sealing ring 5 can be effectively prevent to slip, play better seal effect.
Specifically, the first annular sealing ring 5 include be inserted into the first insertion section 7 in the first annular installation position 6,
It is fixedly arranged in the middle part of first insertion section, 7 outer surface and protrudes from the first stop section 8, fixed of 7 outer surface of the first insertion section
In the 7 outer surface end of the first insertion section and protrude from first sealing 9 on 7 surface of the first insertion section, first sealing
9 height of portion is higher than 8 height of the first stop section.Preferably, which is the first ring that cross section is " F " shape
