Abstract
A kind of borescope stopper structure, comprises plug, pin, spring, pin rod; Wherein: plug leading portion is sexangle blanking cover, rear is cavity right cylinder, is external thread structure in the middle of right cylinder, is processed with circular annular groove, and is processed with a pin-and-hole in the outside of annular groove at right cylinder on the cavity of tail end; Pin rod is cylindrical structure, and be processed with column type boss respectively at the head of pin rod and middle part, can block pin and spring, the tail structure of pin rod is the conical structure that can increase sealing range; The rear of plug, with pin rod hole, is wherein placed with spring in the middle of plug and pin rod; Pin embeds inner along the pin rod hole of plug rear.Advantage of the present utility model: when inside and outside casing mount pad concentricity has certain deviation, just can make the unstressed installation of inside and outside casing by the regulating power of borescope plug self.There is anti-drop function, overcome the defect of split type plug, have the advantage that structure is simple, reliability is high simultaneously concurrently.
Description
Technical field
The utility model relates to borescope mount pad and stopper structure, particularly a kind of borescope stopper structure.
Background technology
In modern gas turbines and test unit thereof, conveniently observe and keep in repair, usually needing to design borescope mount pad and plug on the critical piece of engine.But because gas turbine structure is very complicated, inside and outside casing borescope instrument connection can not integrally be processed, and causes decentraction between holes, and this just needs self to be regulated by borescope plug.The plug that we usually adopt be do not have Self-regulation ability or regulating power less, have directivity, during installation, often produce unnecessary mount stress, affect gas turbine test run safety; Can produce again situation about often cannot dismantle during parking checking, these bring inconvenience all to the operation and maintenance of engine.
Utility model content
The purpose of this utility model is to provide a kind of novel borescope plug, when inside and outside casing mount pad concentricity has certain deviation, do not need to add the inside and outside casing mount pad of work or reconditioning borescope plug, just can make the unstressed installation of inside and outside casing by the regulating power of borescope plug self, spy provides a kind of borescope stopper structure.
The utility model provides a kind of borescope stopper structure, it is characterized in that: described borescope stopper structure, comprises plug 1, pin 2, spring 3, pin rod 4;
Wherein: plug 1 leading portion is sexangle blanking cover, rear is cavity right cylinder, is external thread structure in the middle of right cylinder, is processed with circular annular groove, and is processed with a pin-and-hole in the outside of annular groove at right cylinder on the cavity of tail end;
Pin rod 4 is cylindrical structure, and be processed with column type boss respectively at the head of pin rod and middle part, can block pin 2 and spring 3, the tail structure of pin rod 4 is the conical structure that can increase sealing range;
The rear of plug 1, with pin rod hole, is wherein placed with spring 3 in the middle of plug 1 and pin rod 4; Pin 2 embeds inner along the pin rod hole of plug 1 rear.
Between pin rod and plug, spring is installed, makes it keep impaction state, both can ensure that part has the modulability of certain nargin, its stability under certain stress can be ensured again.
Advantage of the present utility model:
Borescope stopper structure described in the utility model, when inside and outside casing mount pad concentricity has certain deviation, do not need to add the inside and outside casing mount pad of work or reconditioning borescope plug, just can make the unstressed installation of inside and outside casing by the regulating power of borescope plug self.And this kind of borescope plug has anti-drop function, overcomes the defect of split type plug, have the advantage that structure is simple, reliability is high concurrently simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is borescope stopper structure schematic diagram.
Embodiment
Embodiment 1
Present embodiments provide a kind of borescope stopper structure, it is characterized in that: described borescope stopper structure, comprise plug 1, pin 2, spring 3, pin rod 4;
Wherein: plug 1 leading portion is sexangle blanking cover, rear is cavity right cylinder, is external thread structure in the middle of right cylinder, is processed with circular annular groove, and is processed with a pin-and-hole in the outside of annular groove at right cylinder on the cavity of tail end;
Pin rod 4 is cylindrical structure, and be processed with column type boss respectively at the head of pin rod and middle part, can block pin 2 and spring 3, the tail structure of pin rod 4 is the conical structure that can increase sealing range;
The rear of plug 1, with pin rod hole, is wherein placed with spring 3 in the middle of plug 1 and pin rod 4; Pin 2 embeds inner along the pin rod hole of plug 1 rear.
