In order to utilize optical fiber properties better, need carry out various scientific experiments to it, often need in the test optical fiber is fixed, and optic fibre force is had certain requirement, and traditional machine tool class anchor clamps are unsuitable for the tiny optical fiber of clamping, and bad assurance dynamics in clamping, the destruction of easily causing optical fiber, existing optical fiber stationary fixture versatility is poor, complex structure, the manufacturing cost height, flexibility is low, complex operation.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, be easy to install, easy to operate optical fiber stationary fixture.
Technical scheme of the present invention is as follows:
The present invention mainly comprises eccentric wheel, push rod, pressing plate and clamp base, wherein clamp base is the inverted T shape structure, the eccentric wheel base is fixed on the top of clamp base riser one side, eccentric wheel is installed on the above-mentioned eccentric wheel base by eccentric key, eccentric outer rim is provided with screw, and handle is threaded with eccentric wheel.Below eccentric wheel, the push rod base that has through hole is fixed on the bottom of above-mentioned clamp base riser the same side, push rod passes above-mentioned through hole and is arranged on the push rod base, push rod is by the push rod cap, inner spring, push rod housing and mark post are formed, the push rod cap contacts with above-mentioned eccentric wheel outer rim, the push rod cap is nut type, push rod housing is provided with small one and large one notch cuttype hole, the macropore top is provided with screw thread in order to fixing push rod cap, and the mark post of T font is put into aperture, and mark post and push rod housing are matched in clearance, be provided with inner spring between push rod housing inner push-rod cap and the mark post, be provided with scale at mark post, its bottom is provided with through hole, is used for inserting pressure plate stud and connects the matrix pressing plate.Be provided with outer spring outside push rod housing, this outer spring is respectively against the last plane of push rod cap and push rod base.Both sides at the clamp base transverse slat corresponding with above-mentioned pressing plate are provided with the width holding plate, and this width holding plate is two relative U-shaped plates, fixes by screw respectively.Be provided with 2-4 through hole at the clamp base transverse slat, in order to anchor clamps are connected and be fixed on the equipment such as lathe.
During use, at first upwards driving handle causes under the push rod spring action outside and upsprings, optical fiber is passed between width holding plate plate, regulate width holding plate distance between plates from, optical fiber is contacted with the width holding plate, tighten the screw on the width holding plate, rotate handle then, make the pressing plate pressed fiber, the big I of thrust is reflected by the mark post scale value.Eccentric wheel can keep good good self-locking state in the whole operation process.Upwards driving handle makes under the push rod spring action outside and upsprings, and unscrews the screw on the width holding plate, enlarge distance between plates from, take out optical fiber.
The present invention compared with prior art has following advantage:
(1) simple for structure, can self-locking, easy to operate.
(2) the stressed size of optical fiber can be controlled by the stroke of spring, and the appearance of optical fiber situation, reliability height can be effectively avoided damaging by pressure.
(3) with turnable pressing plate pressed fiber, regulate the location of width holding plate, be applicable to the various optical fiber of clamping, and can be flexibly, accurately optical fiber is positioned, clamps, and can not damage the optical fiber crust, optic fibre force is even, security is good.
