Specific embodiment
For the ease of those of ordinary skill in the art understand and implement the present invention, below with reference to embodiment to the present invention make into
The detailed description of one step, it should be understood that implementation example described herein is merely to illustrate and explain the present invention, and is not used to limit
The fixed present invention.
As shown in Figures 1 to 3, a kind of overstable optics cavity, including cavity 1 are provided with light hole 2, light hole 2 in cavity 1
Central axis it is conllinear with the central axis of cavity 1；The both ends of light hole 2 are respectively arranged with first end face 3 and second end face 4,
First end face 3 is parallel with second end face 4 and is each perpendicular to the central axis of light hole 2；The middle part external circumferential of cavity 1 is provided with
First bump 5, the second bump 6 and third bump 7, the first bump 5, the second bump 6 and third bump 7 are uniform
It is distributed on distribution circle, is distributed the round center of circle and is located on the central axis of light hole 2, and be distributed circle place plane perpendicular to light passing
The central axis in hole 2, and the plane for being distributed circle place is the plane of symmetry of cavity.
There are the first hysteroscope 8 and the second hysteroscope 9, the first hysteroscope 8 and the second hysteroscope 9 in first end face 3 and second end face 4 respectively
Central axis that is parallel and being each perpendicular to light hole 2.
Cavity 1 passes through adapter ring 10, and the first bump 5, the second bump 6 and third bump 7 connect with adapter ring 10
It connects.The fixation of realizing optics cavity is fixed in other mechanical structures by adapter ring again.
The long relationship between vibration acceleration of the vibration sensing degree of optics cavity, i.e. optics cavity chamber, depends on two factors:
First, deformation of the cavity under acceleration；Second, it assembles deformation of the frame of cavity under acceleration and causes extruding to cavity
Lead to the deformation of cavity.Since cavity 1 has geometrical symmetry, the location and shape of bump (5,6,7) also have the design
Geometrical symmetry, when cavity 1 is supported by bump (5,6,7), the change of cavity length of cavity 1 and the single order of vibration acceleration are closed
System is automatically zero, minimizes the long variation of cavity chamber caused by the deformation under acceleration, and bump in designing (5,6,
7) quantity is 3, and the cavity taken into account fixed demand while reduces the quantity of support, reduces the opposite shape between bump
Change of cavity length caused by extruding caused by becoming and being displaced to optics cavity, to guarantee that the long variation of chamber is insensitive to vibrating.Chamber
Body 1 is fixed in other mechanical structures again by adapter ring 10 can further decrease influence of the external vibration to optics cavity.Together
When solid and reliable fixed form, Ke Yibao used to the fixation in other mechanical structures again due to cavity 1 to adapter ring 10
Card cavity 1 can bear stronger vibration without shifting or damaging, suitable for that can carry the use with a variety of non-lab environments.
As an implementation, the first bump 5 on cavity 1, the second bump 6 and third bump 7 can be with
Cavity shapes, and can also be fixed on cavity 1 using stickup or other modes；Material system identical as cavity 1 can be used
Work is also possible to different materials；It can be cylindrical body, be also possible to other shapes.
As another embodiment, cavity 1 can be biconial, be also possible to cylindrical or other shapes.
It should be pointed out that specific embodiment described in the present invention only illustrate the spirit of the present invention by way of example.This
The technical staff of technical field that the present invention belongs to can make various modifications or additions to described specific embodiment or adopt
It is substituted with similar mode, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
