Abstract

The utility model relates to a fiber bearing and winding disk which is buttoned and bonded by two symmetrical disk bodies, comprising a reel, a flange arranged on the two ends of the reel and a center hole arranged on the reel center through the disk body. The difference is that both sides of the flange are provided with two elliptic wire-pass holes, the inner side of external diameter of the flange is provided with a circular arc chamfering, and the joint of the outside of the flange and the reel is provided with an arc transition stiffener. The utility model has the advantages of reasonable structure, high rigidity and intensity, high veracity of the fiber testing date on the fiber bearing and winding disk, fine using and fiber winding performance.

Description

Optical fiber winding dish

The utility model relates to a kind of optical fiber winding dish that is used for winding optical fiber.

In the production run of optical fiber cable, the needs of producing for satisfying, depositing and transport, normally with finished product optical fiber on the optical fiber winding dish of making to plastics.Existing optical fiber winding dish includes reel and is located at the ring flange at reel two ends, and the middle part of winding dish is provided with center pit, and winding dish and each several part link by dowel, to alleviate the weight of disk body.Because the structure setting at ring flange and other position is also desirable not to the utmost, often cause on the optical fiber winding dish optical fiber test data inaccurate, it is bad to line up weight, problems such as loose ends: have the high problem of insufficient strength in addition.

The purpose of this utility model be the problem that exists at prior art and design a kind of rational in infrastructure, intensity height, the optical fiber winding dish that usability is more excellent.

For achieving the above object, the technical solution of the utility model is: the disk body by the two-section symmetry fastens bonding forming, include reel 7, be arranged at the ring flange 5 at reel two ends and be positioned at the center pit that runs through disk body 2 at reel middle part, its difference is to offer two oval-shaped wire holes 1 in the ring flange symmetria bilateralis, circular arc chamfering 10 is established in the external diameter inboard of ring flange, and the joining place with reel outside ring flange radially is provided with arc transition reinforcement 4.

The utility model has the advantages that: 1, symmetry is offered two oval-shaped wire holes, single relatively square wire hole, and its dynamic balance performance is good, and optical fiber is even flexural loading on wire hole, can improve the accuracy of optical fiber test data on the optical fiber winding dish; 2, establish circular arc chamfering at the ring flange external diameter, both helped the coiling of winding dish optical fiber when high speed rotating, can avoid of the damage of sharp right angle again optical fiber; 3, whole winding dish possesses rigidity and intensity is preferably arranged, and it is reasonable that structural behaviour more becomes.

Fig. 2 is the A-A cut-open view among Fig. 1.

Fig. 3 is the B-B cut-open view among Fig. 2.

Fig. 4 is the C-C broken section enlarged drawing among Fig. 3.

Further specify embodiment of the present utility model below in conjunction with accompanying drawing, the winding dish fastens bonding forming by the disk body of two-section symmetry mutually by the round button zygostyle that is located at the reel inner face, include the ring flange 5 at reel 7 and reel two ends, the contiguous reel of the upper and lower sides of ring flange place offers the oval wire hole 1 of two symmetries, be provided with circular arc chamfering 10 in ring flange external diameter inboard, the outside of ring flange and the joining place of wire spool are provided with arc transition reinforcement 4 radially, on the end plate of the two ends of reel, be provided with 2-4 fan-shaped hand-hold hole 3, the middle part is provided with the center pit 2 that runs through cylindrical shell, the cylindricality inner face (inwall) of reel is installed the round button zygostyle 6 that axially stretches out a section along circumferential correspondence, the round button zygostyle can be along many of circumferential layings, the two-section disk body fastens mutually by the round button zygostyle, junction with the two ends end plate in reel is installed on diagonal brace dowel 8, the diagonal brace dowel can be between two round button zygostyles, establish 1-2 between per two round button zygostyles, step place at the end plate inner face also can be provided with reinforcement 9, and the rigidity of winding dish and intensity are further improved.
