[0029] In one embodiment, please refer to Figures 1 to 4 , the present utility model provides a simple and rapid optical fiber line pressing structure, including:

[0030] A bracket 1, a circular flange 11 and a limit pin 12 provided on the bracket 1, and the circular flange 11 is used for inserting an optical fiber line;

[0031] A pressing unit 2, the pressing unit 2 includes an elastic strip 21 and a positioning ring 22. The elastic strip 21 is an opening arc structure around the circular flange 11, and the opening direction faces the limit pin 12. The positioning ring 22 is a closed ring structure around the limit pin 12 and is used to limit the compression stroke of the elastic strip 21;

[0032] A force - applying unit 3, the force - applying unit 3 is used to apply a force towards the limit pin 12 to the pressing unit 2. When the pressing unit 2 is subjected to a force towards the limit pin 12, the elastic strip 21 undergoes a bending deformation to close the opening so that the optical fiber line inserted into the circular flange 11 is pressed tightly.

[0033] In one embodiment, the pressing unit 2 further includes: a force - receiving strip 23, the force - receiving strip 23 is integrally connected to the elastic strip 21 and the positioning ring 22. The force - applying unit 3 applies a force to the force - receiving strip 23, causing the elastic strip 21 to bend and deform to close the opening. As Figures 1 - 4 shown, the elastic strip 21 bends downward, the opening closes, and the elastic strip 21 presses tightly the optical fiber line inserted into the circular flange 11.

[0034] In one embodiment, as Figure 1 shown, the force - applying unit 3 is a flywheel rotating shaft. The bracket 1 further includes a first card slot 13, and the first card slot 13 is provided with side holes that cooperate with the flywheel rotating shaft. The side holes are used for axially buckling the flywheel rotating shaft. The flywheel rotating shaft can be fixed and rotated through the side holes on both sides of the first card slot 13 on the bracket 1. During assembly, the two ends of the shaft of the flywheel rotating shaft are forcibly snapped into the corresponding holes on the bracket 1 along the corresponding sliding grooves on the bracket 1. For the convenience of installation, the bracket 1 should have a certain toughness. Practice shows that a plastic bracket can be easily snapped in without leaving marks and can also prevent the flywheel rotating shaft from slipping out after being snapped into the corresponding holes on the bracket 1 through the sliding grooves.

[0035] In one embodiment, a one - way coupling or a handle or a pull - handle or a pull - rod, etc. can also be used as the force - applying unit 3, as long as it can apply a force towards the limit pin 12 to the force - receiving strip 23 to enable it to bend and deform. The present application does not limit this.

[0036] In one embodiment, as Figures 1 to 4 shown, the figure shows the optical fiber line quick - clamping structure for clamping two optical fiber lines. The circular flange 11 includes a first circular flange 111 and a second circular flange 112, and the limit pin 12 includes a first limit pin 121 and a second limit pin 122; the elastic strip 21 includes a first elastic strip 211 and a second elastic strip 212, and the positioning ring 22 includes a first positioning ring 221 and a second positioning ring 222; the first circular flange 111 corresponds to the first elastic strip 211, and the first limit pin 121 corresponds to the first positioning ring 221; the second circular flange 112 corresponds to the second elastic strip 212, and the second limit pin 122 corresponds to the second positioning ring 222.

[0037] In another embodiment, the first circular flange 111 and the second circular flange 112 are arranged side by side. The two optical fiber lines are respectively inserted into the first circular flange 111 and the second circular flange 112 side by side. At this time, when a force is applied to the force-bearing strip 23 towards the limit pin 12, the first elastic strip 211 and the second elastic strip 212 can be bent and deformed without passing through the force-bearing rod 24, so as to clamp the corresponding optical fiber lines respectively.

[0038] In another embodiment, the number of optical fiber lines increases, and the corresponding circular flanges 11, limit pins 12, elastic strips 21, and positioning rings 22 all increase accordingly. Their distribution can be longitudinal distribution, transverse distribution, or matrix distribution, as long as the clamping force received by each optical fiber line can be approximated.

[0039] In one embodiment, the pressing unit 2 further includes a force-bearing rod 24. The force-bearing rod 24 is integrally connected to the force-bearing strip 23 and the second elastic strip 212. When the force-bearing strip 23 is pressed, the force-bearing rod 24 is pressed, so that the second elastic strip 212 is bent and deformed to close the opening.

[0040] In one embodiment, as Figure 4 shown, the bracket 1 is installed inside the housing of the optical fiber amplifier. Figure 4 The dotted line in the figure indicates the housing of the optical fiber amplifier. After assembling the force-applying unit 3 and the pressing unit 2 onto the bracket 1, the bracket 1 is then installed into the housing of the optical fiber amplifier. By opening holes at positions corresponding to the positions of the elastic strips 21 of the pressing mechanism 2 or the circular flanges 11 of the bracket 1 on the housing, at this time, the pressing unit 2 is wrapped by the housing and will not be exposed on the surface of the housing, which is beautiful and convenient for the optical fiber lines to be inserted into the pressing unit 2. And the force-applying unit 3 is exposed on the surface of the housing, which is convenient for force application control.

[0041] For the present utility model, the un-described parts are prior arts.

[0042] The above is only the preferred specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
