Hanging device for optical fiber performs

Abstract

The invention discloses a hanging device for optical fiber performs. The hanging device comprises a base, a vertical rod arranged on the base, and a plurality of connectors arranged on the vertical rod. The optical fiber performs are vertically arranged and connected to the corresponding connectors. The hanging device is characterized in that a clamping part movably connected to the vertical rod is arranged on the vertical rod and comprises installing rings arranged on the vertical rod, multiple ribs arranged on the installing ring, and positioning rings installed at the ends, away from the installing rings, of the ribs; the number of the ribs is consistent with that of the connectors, and the middles of the optical fiber performs are embedded into the positioning rings. By means of the structure, the installing rings installed on the clamping part on the vertical rod are connected to the vertical rod, the positioning rings connected with the installing rings through the ribs encircle the vertically-arranged optical fiber performs, the upper ends of the optical fiber performs are connected with the connectors, the middles of the optical fiber performs are connected with the positioning rings, and therefore no swinging phenomenon exists in the vertically-arranged optical fiber performs when optical fibers are drawn.

Description

technical field [0001] The invention relates to an optical fiber preform suspension device, in particular to an optical fiber preform suspension device with reliable installation and positioning. Background technique [0002] Optical fiber preform is the raw material for manufacturing quartz series optical fiber, specifically, it is a prefabricated rod used to draw optical fiber, usually sintered from silica granular material. As known in the industry, in the process of drawing an optical fiber from a prefabricated rod, that is, an optical fiber preform, it is necessary to suspend and fix the prefabricated rod on a suspension device in a suspended and fixed manner. There are following disadvantages in the mode that adopts earlier at present: 1, owing to have used the eccentric ring that has lock hole, thereby need to make the end of optical fiber preform tail handle form a ball head that can be limited by lock hole, so the processing of optical fiber preform 2. Because the ...

There are following disadvantages in the mode that adopts earlier at present: 1, owing to have used the eccentric ring that has lock hole, thereby need to make the end of optical fiber preform tail handle form a ball head that can be limited by lock hole, so the processing of optical fiber preform 2. Because the optical fiber preform is hung on the optical fiber preform limiting mechanism in an eccentric state, that is to say, the longitudinal center of the optical fiber preform is not consistent with the longitudinal center of the quartz hanging rod, and because the optical fiber preform The ball head at the end of the tail handle is in an unfixed free state, so it is unavoidable to wobble during the process of drawing the optical fiber, and there is even the risk of accidents caused by the ball head jumping out of the opening slot that passes through the lock hole
