Specific implementation mode
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
As shown in Figures 2 to 4, the embodiments of the present invention provide a kind of exhaust connection of Engine Block Test,
Including：First tube body 1, one end are equipped with the first locking flange 2, and the first locking flange 2 is by welding described in coaxial be fixed on
The end of first tube body 1；Second tube body 3, the outer diameter of second tube body 3 and the internal diameter of first tube body 1 are adapted, and are formed
Clearance fit, second tube body 3 are co-axially inserted first tube body 1, and second tube body 3 can back and forth be slided along plugging direction
It moves, is slidingly connected on the pipe shaft of second tube body 3 and is useful for being formed the second lock of secure fit with the first locking flange 2
Only flange 4, in unlocked state, second tube body 3 can freely slide, and the second locking flange 4 can on the second tube body 3
It is arbitrary mobile, 5 bolt fixing holes are equipped on 4 corresponding position of the first locking flange 2 and the second locking flange, are building installation
In the process, after the use length for determining exhaust connection, the second locking flange 4 positions on the second tube body 3, the second tube body 3
Redundance is inserted in the first tube body 1, when the first locking flange 2 and the second locking flange 4 are secured together, passes through fixing bolt
It tightens.
Further, it is the relative position of preferably locking the first tube body 1 and the second tube body 3, the first locking flange 2
Inner wall be formed with cone tank 5, the larger diameter end of the cone tank 5 is arranged towards the second locking flange 4, described second
Locking flange 4 is c-type structure, and the second locking flange 4 is radial to be opened up there are one expansion joint 12, and expansion joint 12 is from the second locking
The inner wall of flange 4 extends radially to the outer wall of the second locking flange 4, and the inner wall of the second locking flange 4 is described in
First locking flange 2 extends to form the cone boss 6 coordinated with the cone tank 5, and the cone boss 6 is than in cone tank 5
Diameter is slightly larger, and during cone boss 6 is bonded with cone tank 5,6 stress deformation of cone boss makes the flexible of the second locking flange 4
12 tightening of seam, 2 internal diameter of the first locking flange become smaller, and by 3 stuck fast of the second tube body, the second tube body 3 passes through with the first tube body 1
