Supporting-type optical fiber preform suspension device

Abstract

The invention discloses a supporting-type optical fiber preform suspension device which comprises a pedestal, a vertical post and connectors, wherein an optical fiber preform is vertically arranged and connected to the corresponding connector. The supporting-type optical fiber preform suspension device is characterized in that the vertical post is provided with a clamping part which is flexibly connected to the vertical post; the clamping part comprises a mounting ring, ribs and a supporting structure; the supporting structure is a cylinder of which the central axis is vertically arranged; and the cylinder is provided with a locating hole into which the lower end of the optical fiber preform is embedded. By adopting the structure, the mounting ring on the clamping part mounted on the pedestal is connected to the vertical post, and the lower end of the optical fiber preform is embedded into the supporting structure connected with the mounting ring through the ribs, the upper end of each optical fiber preform is connected with the corresponding connector, and the lower end of each optical fiber preform is connected with the supporting structure, so that the vertically arranged optical fiber preform can not swing in the optical fiber drawing process.

Description

technical field [0001] The invention relates to a jack-up type optical fiber preform suspension device, in particular to a jack-up type 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 ...

Problems solved by technology

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
