Abstract
The utility model belongs to the aeroengine field and especially relates to a borescope base structure. The borescope base structure comprises a borescope cover 1, a spring 2, a borescope plug 3 and a borescope base 4, wherein the spring 2 is wrapped by the borescope cover 1, the borescope plug 3 and the borescope base 4. The advantages are that the borescope base structure is equipped with fewer parts, exhibits good reliability, is reliable in sealing during an experiment, is convenient and rapid to dismount if a borescope is needed to test after the experiment, is small in size and compact in structure, is equipped with fewer components, is simple to machine, and is convenient to mount and dismount.
Description
Technical field
The utility model belongs to the aeromotor field, particularly relates to a kind of borescope hole holder structure.
Background technology
The reliable sealing during for warranty test due to traditional borescope hole seat, complicated structure, number of spare parts is many, so relative cost is higher, install and dismounting complicated.
Summary of the invention
Goal of the invention: a kind of novel borescope holder structure is provided, and number of spare parts reduces a lot, and good reliability.
Technical scheme: a kind of borescope hole holder structure, comprise that borescope lid 1, spring 2, borescope stop up 3, borescope seat 4, described borescope lid 1 and borescope stop up 3 and borescope seat 4 spring 2 is wrapped.
Described borescope seat 4 shape of the casing 5 at place, measuring position as required is provided with the inclined-plane in the bottom.
Beneficial effect: a kind of borescope holder structure of the utility model, number of spare parts is few, and good reliability seals reliably during experiment, and when needing after test to check with borescope, convenient disassembly is rapid.The utility model size is little, compact conformation, and component part is few, and processing is simple, and installation and removal are convenient.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, sees also Fig. 1 to Fig. 6.
A kind of borescope hole holder structure comprises borescope lid 1, spring 2, borescope obstruction 3, borescope seat 4, and described borescope lid 1 and borescope obstruction 3 and borescope seat 4 wrap spring 2.
Described borescope seat 4 shape of the casing 5 at place, measuring position as required is provided with the inclined-plane in the bottom.During actual the use, borescope seat 4 can with outer casing welding, borescope stops up the lower end bulb and coordinates with perforate on inner body 6.
Principle of work of the present utility model is: at first spring 2 is put into borescope lid 1 during assembling, then borescope lid 1 is screwed on borescope base 4, and with the lock silk, borescope lid 1 is connected with borescope base 4, afterwards borescope obstruction 3 is put into by the profile hole that borescope covers on 1, when putting into, lower pressing spring 2, then half-twist, decontrol borescope and stop up 3, the hangers in borescope obstruction 3 just can embed in the groove of borescope lid 1 inside surface like this, thereby guarantees sealing reliably and fix.In the time of need to carrying out boresoope inspection, only need that borescope is stopped up 3 and pin, then descend pressing spring 2, and half-twist, can take out.
Claims (2)
1. borescope hole holder structure, it is characterized in that, comprise that borescope lid (1), spring (2), borescope stop up (3), borescope seat (4), described borescope lid (1) and borescope stop up (3) and borescope seat (4) wraps spring (2).
2. a kind of borescope according to claim 1 hole holder structure, is characterized in that, described borescope seat (4) shape of the casing (5) at place, measuring position as required is provided with the inclined-plane in the bottom.
