Abstract

The utility model relates to a protection cover for a wound optical fiber for packaging optical fibers. The protection cover for a wound optical fiber comprises two symmetrical semi-circle cover casings, wherein, concave annular clamping grooves are arranged on both ends of the inner side of the semi-circle cover casing. The two semi-circle cover casings are hinged along a circumferential direction end. A gathering handle is arranged at the other end of the semi-circle cover casing. A connection fastening device is arranged on both ends of the handle. The connection fastening device is a return expansion fastening device. An anti-rolling boss is arranged on the circumferential direction outer side of the semi-circle cover casing. The utility model has the advantages of convenient utilization, long service life for fastening and reliable locking performance for fastening. Particularly, a mutually interlaced fastening structure is adopted. Thus, the protective performance of the protection cover can be further reinforced.

Description

Dish dress fiber optic protection cover

The utility model relates to a kind of dish dress fiber optic protection cover that is used for the optical fiber packing.

Normally install around in fiber reel after the elongated optical fiber machine-shaping as silk, the optical fiber that installs around is like this loading the damage that is subject to the effect of foreign object when transporting and causes optical fiber because what protection case the outside has.Dish dress fiber optic protection cover is provided with at the problem of above-mentioned existence; but existing dish dress fiber optic protection cover is the semi arch lagging hinge by two opening and closing to form; close up the back and become round barrel shape; its inboard, two ends is provided with matrix ring-type draw-in groove; just in time fiber reel is clamped and be fixed in the protective cover, the optical fiber that circumferentially installs around is protected.When reality was used, existing dish dress fiber optic protection cover existed easy loosening the strutting of case buckle, and the situation that causes dish dress optical fiber to deviate from protective cover has weakened the effect of its protection optical fiber.

The purpose of this utility model is to provide a kind of buckle firm, uses the stronger dish dress fiber optic protection cover of protective value.

The technical scheme that realizes the utility model purpose is as follows: the

semi-circular case

3,8 that includes two symmetries, the inboard two ends of semi-circular case are provided with matrix ring-type draw-in groove 7, two semi-circular cases are hinged along a circumferential end, the other end is provided with and closes up handle, be provided with the Connection Card buckle device at two of handle, its difference is that the Connection Card spiral-lock is changed to back-shaped inflating clip buckle device, is provided with anti-roll boss 4 laterally in the week of semi-circular case.

Press such scheme; back-shaped inflating clip buckle device of the present utility model is made of back-shaped expansion button 9 and bayonet socket 1; their corresponding respectively outer both sides of handle bracket that are arranged at two semi-circular cases; two back-shaped expansion buttons and bayonet socket can interlacedly be provided with, and the buckle ability of protective cover is further strengthened.

Good effect of the present utility model is to have adopted back-shaped inflating clip buckle device; not only close up and open conveniently freely; the long service life of buckle; not fragile inefficacy; and the locking property of buckle is reliable; especially adopt interlaced buckle structure, the locking locking property of buckle is further improved, thereby the barrier propterty of protective cover is further strengthened.In addition, outside case, set up defences and roll boss, also can strengthen the stationarity that protective cover is placed, avoid coiling rolling and the collision of dress optical fiber when transportation and dormant state as far as possible, make the usability of protective cover more become perfect.

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

Embodiment 1 is as Fig. 1,2,3,5,6, shown in 7, include the semi-circular case 3 of two symmetries, 8, become cylinder barrel shaped altogether, the inboard two ends of semi-circular case are provided with matrix ring-type draw-in groove 7, two semi-circular cases are staggeredly equipped with the hinge cover 5 of arc bulk and the chain pin 6 of phase configuration along a circumferential end, become hinge after the obvolvent mutually, two semi-circular cases are symmetrically arranged with the outwardly directed handle 2 that closes up along the circumferential other end, 10, closing up handle, to separate the cross section be semi-circular or the semiellipse type, be provided with four undulatory finger recesses vertically, so that guide and support, buckle 9 and bayonet socket 1 in the back-shaped expansion of the handle bracket arranged outside correspondence of closing up the handle two ends, constitute back-shaped inflating clip buckle device, wherein back-shaped expansion button and the interlaced setting of bayonet socket as shown in Figure 3, promptly are provided with a back-shaped expansion button 9 and a bayonet socket 1 respectively at the two ends of a semi-circular case handle bracket, in addition, in the outside, two ends of semi-circular case anti-roll boss 4 can be set also.Present embodiment is a kind of split-type structural, the structure of each semi-circular case is all identical with shape, can be hinged with chain pin by their hinge cover or separate, so not only be convenient to make, and after one of them semi-circular case damages, only need to change a semi-circular case, to reach the purpose of saving cost.

Another embodiment of the present utility model is shown in Fig. 4,8,9, the main difference part of it and a last embodiment is that two semi-circular cases are hinged with connecting band 11, and the back-shaped expansion button 9 in the handle bracket outside and bayonet socket 1 are provided with in the same way or also can be crisscross arranged.
