Abstract
The utility model discloses an optical fiber macrobend loss testing tool, which comprises rocking bars, flanges and a testing wheel spindle. The testing wheel spindle is arranged between two flanges and is provided with a groove which can be opened and closed. The flanges are provided with the rocking bars for controlling opening and closing of the groove. In comparison with the prior art, the optical fiber testing tool provided by the utility model is adopted to effectively reduce operational influence and raise testing efficiency. According to the utility model, optical fiber is firstly wound around the testing wheel spindle; after winding, the rocking bars are pressed so as to change the depressed groove from a cylinder state to a partial depressed state and adjust the optical fiber from a strained tensed state to an unstrained state. The optical fiber macrobend loss testing tool provided by the utility model has a simple structure, has strong practicality, and is applicable to being widely used in the industry.
Description
Technical field
The utility model relates to the fiber manufacturing industry, is specifically related to a kind of macrobending loss test fixture of optical fiber.
Background technology
In the fiber manufacturing industry, it is very important that the macrobending loss of optical fiber detects, existing optical fiber in the macrobending loss test process normally with Optical Fiber Winding on the test wheel shaft of common column, because optical fiber is in winding process, itself just be in stressed tight state, so just caused test result inaccurate, artificial test error is higher.
The utility model content
The utility model purpose: the utility model provides the macrobending loss test fixture of the optical fiber that a kind of test result error is little, testing efficiency is high in order to solve the prior art deficiency.
Technical scheme: a kind of macrobending loss test fixture of optical fiber comprises rocking bar, flange and test wheel shaft; Described test wheel shaft is located between two flanges, is provided with the groove that can open and close at the test wheel shaft, is provided with the rocking bar that opens and closes for the control groove at described flange.
As optimization, described bottom portion of groove be provided be used to control that described groove opens and closes hinge.
Beneficial effect: the macrobending loss test fixture of optical fiber described in the utility model, compared with prior art, effectively reduce operating influence, improve testing efficiency, the utility model is at first being tested Optical Fiber Winding on the wheel shaft, after winding, press rocking bar, then but recessed groove becomes the local dent state from the cylinder state, and optical fiber is adjusted to the state of not stressing from stressed tight state, can effectively reduce artificial test error after the test, the more common column frock of efficient is improved simultaneously, the utility model is simple in structure, and is practical, is fit to widely used within the industry.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail:
As shown in Figure 1, a kind of macrobending loss test fixture of optical fiber comprises rocking bar 1, flange 2 and test wheel shaft 3; Test wheel shaft 3 is located between two flanges 2, is provided with the groove 4 that can open and close at test wheel shaft 3, is provided with the rocking bar 1 that opens and closes for control groove 4 at flange 2, groove 4 bottoms be provided with for control groove 4 open and close hinge.
Principle of work: first testing fiber is wrapped on the test wheel shaft, after winding, press rocking bar, then but recessed groove becomes the local dent state from the cylinder state, optical fiber is adjusted to the state of not stressing from stressed tight state, begin can effectively reduce artificial test error after the test, the more common column frock of efficient is improved simultaneously.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
