6 for limiting the limited step 8 for being fitted to 3 junction of hole 2 and lower opening, the limited step 8 by upper hole 2 and lower opening 3 not
With aperture and formed, to limit the second limiting section 6, the aperture in upper hole 2 is more than the aperture of lower opening 3.To prevent indent
Cascaded surface, lower 7 bottom surface of eccentric part match with corresponding casing pipes' analysis shape.Positioning assembling is used under with eccentric part 7 at present
In hole 3, to realize equipped positioning, the eccentric distance in the eccentric distance and eccentric direction of lower eccentric part 7 and lower opening 3 upper hole 2 relatively
Match with eccentric direction.
And for connector 9, connecting pin 10 is arranged and screws connection with pedestal 1 is connect.
To realize that limit hole cavity configuration is arranged to limit equipped first in the equipped of plug and connector 9, the connecting pin 10
Limiting section 5,5 clearance fit of the first limiting section facilitate connector 9 can opposite first limiting section 5 in limit hole cavity configuration
Rotation.
As shown in Figure 1, a kind of section view knot of embodiment for the borescope plug of the invention to match with pipes' analysis shape
Structure schematic diagram.In this embodiment, connection pedestal 1 is attached to casing, and the bottom surface of connection pedestal 1 is one of casing pipes' analysis
Point, connection pedestal 1 can independent machine-shaping, molding can also be integrally machined with casing, depending on demand.Connect the table of pedestal 1
Protruding out cylindric pedestal 1.1 upwardly, the shape of certain pedestal 1.1 is not limited to cylindric, and peripheral shape is not limited,
It can be the suitable shape such as rectangle, rectangular, taper.The upper hole 2 of the setting of cylindric pedestal 1.1 in the present embodiment and lower opening 3, lower opening
3 relatively upper 2 eccentric a distances of hole, upper hole 2 and lower opening 3 are all provided with and are set to circular through hole, and upper hole 2 is more than the aperture of lower opening 3, together
Internal thread is arranged in the middle and upper part of Shi Shangkong 2.Wherein other than circular through hole is arranged, shape is not restricted the shape of lower opening 3, can
To there is the setting of other various shapes.
For plug 4, in the embodiment shown in fig. 1, the first limiting section 5, the second limiting section 6, the lower eccentric part of plug 4
7 are disposed as cylindrical shape, and certain lower eccentric part 7 can be equipped with according to the shape of lower opening 3.
Wherein the first limiting section 5, the second limiting section 6 are coaxially set, that is to say, that the two is not relatively eccentric.And lower bias
Portion 7 is then with respect to the eccentric a distance of the second limiting section 6, wherein the eccentric distance and bias of 7 opposite second limiting section 6 of lower eccentric part
Above the eccentric distance and eccentric direction in hole 2 match relatively with lower opening 3 in direction.
And for connector 9, in the embodiment shown in fig. 1, cylinder is arranged in 9 global sections t shape of connector
Shape connecting pin 10 and the head 9.1 being connect with 10 top of connecting pin.Wherein head 9.1 is preferably provided to outer-hexagonal head, convenient for pulling
Hand operates, and certain head peripheral shape can be not limited to outer-hexagonal shape, can carry out the setting of required shape according to demand.Simultaneously
In the present embodiment, outer-hexagonal head be more than connecting pin 10 size, connecting pin 10 lateral wall setting external screw thread with it is described
The internal thread threaded engagement connection in upper hole 2.In addition connecting pin 10 also sets up vestibule 11, the lower end perforation connecting pin 10 of vestibule 11
Bottom, setting is cyclic annular on the inner wall of the vestibule 11 matches tankage 12.And the first limiting section 5 of plug 4 then limits and is fitted in vestibule 11
In.
In this embodiment at this time, the limit hole cavity configuration includes that the ring-type being located on 11 wall of vestibule matches tankage 12, energy
It is installed in the cyclic annular elastic collar 13 matched in tankage 12, the shoulder 14 being disposed on the first limiting section 5, the limit of the shoulder 14 exists
To prevent the first limiting section 5 from deviating from vestibule 11 on elastic collar 13.By being equipped with for elastic collar 13 and shoulder 14, not only
Can convenient for the equipped of plug and connector, while can also the limit of the first limiting section of effective guarantee 5 in vestibule 11 without falling, and
First limiting section 5 and 11 clearance fit of vestibule, can realize that connector is rotated relative to the first limiting section, and realize connector and connect
Threaded engagement connection between pedestal.Meanwhile during actually screwing, the length of screw-thread fit between connector and connection pedestal
Degree be less than plug under eccentric part with connect pedestal lower opening length of fit to ensure borescope plug before screwing, plug first stretches into
Lower opening carries out installation guiding, reinforced assembly craftsmanship.
In some embodiments, the shoulder 14 is formed by annular recess 15 being opened on the first limiting section 5, institute
The lower part for stating annular recess 15 extends to the second limiting section 6.The vertical span of annular recess 15 is big, it is easier to which connector is with respect to
One limiting section is rotated.Refer to Fig. 1.
In some embodiments, above connecting pin 10 connection pedestal 1 setting locking wire hole 16 with gas turbine phase
Close component connection.It is passed through with fuse after locking wire hole 16 so that connector to be connect with gas turbine associated components, can realize can
By loosening.
In some embodiments, preset clearance between 11 top of first limiting section 5 and vestibule, that is to say, that the first limit
Position portion 5 and the top of vestibule 11 are not close to close, ensure to limit after the installation of borescope plug in this way plug can have micro movement with
Issuable deformation constraint under preventing different temperatures from changing.
Assembling process：Plug is limited on connector by elastic collar and forms assembly, then by assembly along
Pedestal female threaded shaft is connected to installation, the lower eccentric part of plug is introduced into the lower opening of connection pedestal, then connects extracorporeal thread
It screws in the internal thread of connection pedestal, last connector screws in connection pedestal until connector is adjacent to i.e. with base end face is connect
Complete the assembly of borescope plug.
