Specific embodiment
To describe this utility model below in conjunction with accompanying drawing and specific embodiment in detail, here signal of the present utility model
Property embodiment and explanation be used for explaining this utility model, but be not intended as to restriction of the present utility model.
Referring to figs. 1 to Fig. 3, the utility model discloses a kind of ceramic ring structure of optical fibre gyro, including in a fiber optic loop
End face 1,
Under this symmetrically arranged fiber optic loop lower surface 2 in fiber optic loop upper surface 1, described fiber optic loop upper surface 1 and fiber optic loop
Form one between end face 2 and carry the fiber optic loop of annular groove around anchor ring 3, described fiber optic loop upper surface 1 and 2 points of fiber optic loop lower surface
Do not form a fillet 5 with the connection end of interior ring-side wall 4, wherein, at the edge of described fiber optic loop upper surface 1 or fiber optic loop lower end 2

Ceramic anchor ring and face junction are by ftractureing that stress concentration leads to；Relatively thin, fiber optic loop lower surface 2 is designed in its fiber optic loop upper surface 1
Design is thicker, mainly considers that the fixed form of this ceramic ring structure is to glued joint to fix, wherein fiber optic loop lower surface 2 is splicing portion
Position, fiber optic loop upper surface 1 does not carry out glueing joint link, in order to strengthen the ability bearing bond stress of ceramic ring structure, thickeies light
Fine ring lower surface 2 glueds joint face it is ensured that the reliability gluedd joint of ceramic ring；Its fiber optic loop upper surface 1 is provided with excessively fine skewed slot 6 at two,
It is in symmetrical position in fiber optic loop upper surface 1, the gradient of excessively fine skewed slot 6 should be less than 90 °, fibre skewed slot 6 width and depth excessively
Should according to be determined using optical fiber coating diameter and excessively fine number of times, this excessively fine skewed slot 6 is easy to fiber optic loop around anchor ring 3
Optical fiber upper surface of climbing is fixed, and the optical fiber being simultaneously also convenient for upper surface pulls down to fiber optic loop and is fixed around anchor ring.
Above the technical scheme disclosed in this utility model embodiment is described in detail, used herein specifically
Embodiment is set forth to the principle of this utility model embodiment and embodiment, and the explanation of above example is only applicable to
Help understand the principle of this utility model embodiment；Simultaneously for one of ordinary skill in the art, real according to this utility model
Apply example, specific embodiment and range of application all will change, in sum, this specification content should not be understood
It is to restriction of the present utility model.
