Abstract
A kind of sun-shading cap for test optical fiber instrument, test optical fiber instrument includes instrument body and the fiber grooves for monitoring optical fiber on instrument body, sun-shading cap includes sun-shading cap body and the projection being arranged on sun-shading cap body, the first groove supporting with the projection is provided with above fiber grooves, first bottom portion of groove is provided with the second groove, card column is constituted between second groove and instrument outer wall, and projection is provided with the recess supporting with card column.Installation of this utility model by sun-shading cap, it is possible to achieve instrument device in test process can be very good to cover instrument monitoring area, reduces impact of the natural light in environment to test effect, improves accuracy.Instrument every day use or idle when prevent dust enter instrument detection zone detector test surface on, so as to improve accuracy and reliability of the detector to fiber laser arrays.
Description
Technical field
This utility model is related to fiber-optic monitoring field, especially a kind of sun-shading cap for test optical fiber instrument.
Background technology
Existing fiber-optic monitoring instrument has many shortcomings in test process：Instrument monitoring is covered without good device
Area so that the natural light in environment has a negative impact to testing effect, accuracy.Simultaneously instrument every day use or idle when
Dust is becomed easily infected by, and causes dust to enter on instrument detection zone detector test surface, so that detector is affected to fiber-optic monitoring
Accuracy and reliability.Instrument, is difficult accurately to make optical fiber enter spy when causing to clamp without reference to position in grip optical fiber
Fixed detection zone fiber grooves.
Content of the invention
The technical problem that this utility model is mainly solved is to provide a kind of sun-shading cap for test optical fiber instrument.
This utility model be solve the technical scheme that adopts of above-mentioned technical problem for：
A kind of sun-shading cap for test optical fiber instrument, the test optical fiber instrument include instrument body and instrument sheet
The fiber grooves for monitoring optical fiber on body, the sun-shading cap include sun-shading cap body and are arranged on sun-shading cap body
Projection, is provided with the first groove supporting with the projection above the fiber grooves, it is recessed that first bottom portion of groove is provided with second
Groove, constitutes card column between second groove and instrument outer wall, the projection is provided with the recess supporting with card column.
Further, first recess sidewall is provided with slideway, and the projection is provided with the slide block supporting with slideway.
Further, the projection is provided with the second projection supporting with the second groove.
Further, the slide block is electronic slide block, and the electronic slide block is connected with controller.
The beneficial effects of the utility model are：
Installation of this utility model by sun-shading cap, it is possible to achieve instrument device in test process can be very good to cover
Instrument monitoring area, reduces impact of the natural light in environment to test effect, improves accuracy.Instrument is in every day use or spare time
Prevent dust from entering on instrument detection zone detector test surface when putting, so as to improve detector to the accuracy of fiber laser arrays and can
Lean on property.Instrument, is difficult accurately to make optical fiber enter specific detection zone when causing to clamp without reference to position in grip optical fiber
Fiber grooves.
By being connected together for card column and recess, it is possible to achieve the highly stable placement of sun-shading cap, at the same by slideway with
The setting of slide block, it is possible to achieve raised smoothly up and down in groove.By the second raised setting with the second groove,
May further ensure that the stability that sun-shading cap is arranged.
Description of the drawings
Fig. 1 is a kind of structural representation of specific embodiment of this utility model.
Fig. 2 is the structural representation of this utility model protrusions and the first groove.
In figure：1 is sun-shading cap body, and 2 is the first groove, and 3 is recess, and 4 is the second projection, and 5 is the second groove, and 6 are card
Post, 7 are projection, and 8 is slide block, and 9 is slideway.
Specific embodiment
Please refer to Fig. 1 and Fig. 2, a kind of position specific embodiment of the present utility model.
A kind of sun-shading cap for test optical fiber instrument, the test optical fiber instrument include instrument body and instrument sheet
The fiber grooves for monitoring optical fiber on body, the sun-shading cap include sun-shading cap body 1 and are arranged on sun-shading cap body
Projection 7, be provided with the first groove 2 supporting with the projection above the fiber grooves, first bottom portion of groove is provided with
Two grooves 5, constitute card column 6 between second groove and instrument outer wall, the projection is provided with the recess 3 supporting with card column,
Projection is provided with the second projection 4 supporting with the second groove.
First recess sidewall is provided with slideway 9, and the projection is provided with the slide block 8 supporting with slideway.
Slide block is electronic slide block, and electronic slide block is connected with controller.
Installation of this utility model by sun-shading cap, it is possible to achieve instrument device in test process can be very good to cover
Instrument monitoring area, reduces impact of the natural light in environment to test effect, improves accuracy.Instrument is in every day use or spare time
Prevent dust from entering on instrument detection zone detector test surface when putting, so as to improve detector to the accuracy of fiber laser arrays and can
Lean on property.Instrument, is difficult accurately to make optical fiber enter specific detection zone when causing to clamp without reference to position in grip optical fiber
Fiber grooves.By being connected together for card column and recess, it is possible to achieve the highly stable placement of sun-shading cap, at the same by slideway with
The setting of slide block, it is possible to achieve raised smoothly up and down in groove.By the second raised setting with the second groove,
May further ensure that the stability that sun-shading cap is arranged.
