Description
Technical field
The utility model relates to optical fibre gyros, it particularly relates to a kind of framework for optical fiber gyro.
Background technique
Optical fibre gyro is a kind of Optical rotation sensor based on Sagnac effect, has extensive military and civilian
Background.In order to meet the requirement of practical application, under various circumstances, optical fibre gyro should all have high reliability.Its performance indicator
One of be exactly vibration resistance.Although optical fibre gyro inherently has natural antivibration advantage compared with other kinds of gyro, make
Vibration environment is also exposed in, and adverse effect is led to the problem of to optical fiber gyroscope precision.In general, it should be noted that optical fibre gyro
It is middle insecure using the installation of device (such as circuit board, detector, waveguide, coupler), it will lead to vibration to optical fibre gyro property
Energy index has an impact.In fact, if the fiber optic loop of optical fibre gyro during transportation, tail optical fiber places unreasonable, same meeting
Influence the overall performance of fiber optic loop safety during transportation and optical fibre gyro.
For existing framework for optical fiber gyro to the placement of tail optical fiber mostly there is also some problems, most important problem is tail
Fibre does not pass through arc transition when placing, and optical fiber is easily made to form unfavorable bending in skeleton edges incision, reduces fiber optic loop
Energy.
For the problems in the relevant technologies, currently no effective solution has been proposed.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of framework for optical fiber gyro, can solve
Certainly optical fiber is easy the problems such as bending when entering gyro skeletal internal.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of framework for optical fiber gyro, including columned hollow disk body are designed, is equipped with chassis below the hollow disk body,
It is equipped with bulge loop above the hollow disk body, the chassis, bulge loop and the external side of hollow disc form optical fiber annular groove, the chassis, convex
Side forms mounting portion in ring and hollow disc body, and the bulge loop lower surface is provided with into fine hole, and the bulge loop inner surface is provided with optical fiber hole,
It is described to be communicated into fine hole with optical fiber hole by excessively fine channel.
Further, the chassis diameter is greater than the hollow disk body diameter.
Further, the bulge loop internal diameter is identical as the hollow disk body diameter, and the bulge loop outer diameter is greater than described hollow
Disk body diameter.
Further, the chassis is equipped with fixed screw hole.
Further, the chassis on mounting portion interface be equipped with multiple installation circular grooves.
Further, the excessively fine channel is arc-shaped.
The utility model has the beneficial effects that improving the reliability that tail optical fiber crosses line by the way that arc-shaped excessively fine channel is arranged, having
Effect avoids the case where tail optical fiber is bent when entering skeletal internal；Mounting portion can install other portions needed for optical fibre gyro
Part, integrated level is high, and firm performance is strong, improves the vibration resistance of entire optical fibre gyro.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model

A little attached drawings obtain other attached drawings.
Fig. 1 is a kind of framework for optical fiber gyro structural schematic diagram according to the utility model embodiment.
Fig. 2 is the excessively fine path partially schematic diagram according to the utility model embodiment.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in Figs. 1-2, a kind of framework for optical fiber gyro according to the utility model embodiment, including it is columned
Hollow disk body 1 is equipped with chassis 2 below the hollow disk body 1, is equipped with bulge loop 3 above the hollow disk body 1, the chassis 2, convex
Optical fiber annular groove 4 is formed on the outside of ring 3 and hollow disk body 1, forms mounting portion 5, institute on the inside of the chassis 2, bulge loop 3 and hollow disk body 1
It states 3 lower surface of bulge loop to be provided with into fine hole 31,3 inner surface of bulge loop is provided with optical fiber hole 32, described into fine hole 31 and optical fiber hole 32
It is communicated by excessively fine channel 33.
Preferably, 2 diameter of chassis is greater than hollow 1 diameter of disk body.
Preferably, 3 internal diameter of bulge loop is identical as hollow 1 diameter of disk body, and 3 outer diameter of bulge loop is greater than described hollow
1 diameter of disk body.
Preferably, 2 edge of chassis is equipped with fixed screw hole 21, for fixing fiber optic gyro framework.
Preferably, the chassis 2 on 5 interface of mounting portion be equipped with multiple installation circular grooves 22, for light to be fixedly mounted
Other component needed for fine gyro.
