Description
Technical field
The utility model belongs to field of optical detection, more particularly, to a kind of optical fiber clamping device.
Background technology
With the development of optical non-destructive detection technology, its application in all kinds of quality of agricultural product Fast nondestructive evaluations is year by year
Increase, which can reach in the detection to poultry meat product and do not damage sample, and quickly measure multiple Testing index at the same time.
When being detected using optical detective technology to poultry meat quality, it is desirable to which optical fiber clamping device can fix optical fiber, due to optical fiber
Fibre core is thinner, and clamping force controls the bad degradation that can cause optical fiber, and reliability reduces.
The content of the invention
The technical problem of solution
The purpose of this utility model is to provide a kind of optical fiber clamping device, when for fiber operating, reduces to optical fiber
Clamping damage, ensures the stability of optical fiber property.
Technical solution
The utility model provides following scheme：A kind of optical fiber clamping device, is relaxed by retaining sleeve, fixing sleeve, adjusting set, tune
Spring is rushed, tightens buffer spring and gripper jaw composition.Wherein retaining sleeve base is flange-type structure, and base center has cylinder knot
Structure, cylinder other end are gripper jaw, and middle part is provided with optical fiber holding holes, and there is adjusting spiral shell on gripper jaw and base connecting cylinder surface
Line, base flange outer round surface have fixed thread.Wherein fixing sleeve opens round-meshed barrel shaped structure for bottom surface, no bottom surface side
Barrel-shaped internal circular surfaces have fixed thread, and cooperation is attached with the fixed thread on retaining sleeve.Wherein adjusting set is provided with for top
The hat-shaped structure of bellmouth, is provided with adjusting screw thread close to visor portion internal circular surfaces, is connected with the adjusting screw thread on retaining sleeve
Cooperation is connect, adjusting set outer surface, which is provided with, tightens buffer spring.Wherein tighten on buffer spring one end and adjusting set brim structure
Surface contacts, and other end is contacted with fixing sleeve inside bottom surface, adjusts loose buffer spring to be installed on gripper jaw.Wherein adjust punching of relaxing
Spring one end is contacted with gripper jaw bottom cylinder upper bottom surface, and the other end is contacted with adjusting set top inner surface, and gripper jaw, which passes through, to be adjusted
Section set pyramidal hole.
At work, adjusting set is adjusted toward close to retaining sleeve direction, adjusts loose buffer spring to be in relaxed state at this time, adjust
Locking buffering spring is in compressive state, and the adjustment to adjusting set forms resistance, makes adjusting set adjustment slack-off, when adjusting set is adjusted to
During suitable position, optical fiber is penetrated in optical fiber holding holes, then adjusting set is adjusted along away from retaining sleeve direction, is adjusted at this time
Locking buffering spring is in relaxed state, adjusts loose buffer spring to be in compressive state, the adjustment to adjusting set forms resistance, makes adjusting
The degree of regulation increase of set, slowly adjusts to fiber gripper state.
The beneficial effects of the utility model are：Two buffer springs form resistance to adjusting process during adjusting, make
Degree of regulation increase, reduces the Clamping damage to optical fiber.

Embodiment
Optical fiber is clamped using a kind of optical fiber clamping device of the utility model below in conjunction with the accompanying drawings, for this practicality
New embodiment is described in detail.The following examples illustrate the utility model, but is not used in and limits this reality
With new scope.
A kind of optical fiber clamping device of the utility model is by retaining sleeve 1, fixing sleeve 2, adjusting set 3, adjusts loose buffer spring 4,
Tighten buffer spring 5 and gripper jaw 6 forms.1 base flange outer round surface of retaining sleeve is connected with 2 internal circular surfaces of fixing sleeve by screw thread
Connect, 1 base center periphery of retaining sleeve is connected through a screw thread with 3 internal circular surfaces of adjusting set, and retaining sleeve 1 raises locking buffering spring
5 pass through the top tapered hole of adjusting set 3, adjust loose buffer spring 4 to be sleeved in adjusting set 3, one end connects with 3 upper base surface of adjusting set
Touch, other end is contacted with being sleeved on 2 bottom interior surface of fixing sleeve of the outside of adjusting set 3.The adjusting set 3 is provided with cone for top
The hat-shaped structure of shape through hole, the cone angle of bellmouth are less than 10 °.The gripper jaw 6 shares four, and the bottom surface of every gripper jaw 6 is equal
For a quarter annulus, and vertical section is right-angled trapezium, and busbar and the vertical curve angle of gripper jaw should be less than the top of adjusting set 3
The half of bellmouth cone angle.
When needing to clamp optical fiber, adjusting set 3 is adjusted toward close to 1 direction of retaining sleeve, adjusts loose buffering elastic at this time
Spring 4 is in relaxed state, tightens buffer spring 5 and is in compressive state, the adjustment to adjusting set 3 forms resistance, adjusts adjusting set 3
It is whole slack-off.When adjusting set 3 is adjusted to suitable position, optical fiber is penetrated in optical fiber holding holes, then by adjusting set 3 along away from folder
The direction for holding set 1 is adjusted, and is tightened buffer spring 5 at this time and is in relaxed state, adjusts loose buffer spring 4 to be in compressive state,
Adjustment to adjusting set 3 forms resistance, makes the degree of regulation of adjusting set 3 increase, and slowly adjusts to fiber gripper state.
The utility model has the advantage that compared with existing fiber clamping device：Two buffer springs are exchanged during adjusting
Section process forms resistance, increases degree of regulation, reduces the Clamping damage to optical fiber, and its structure design is simplified, swift to operate.
The above is the preferred embodiment of the utility model, for before the utility model technical principle is not departed from
The improvement or replacement put should be regarded as the scope of protection of the utility model.
