Embodiment Construction

[0009] The hollow shaft 3 is in the shape of a pen barrel, one end is open, and the other end is sealed; Hollow shaft 3 transverse sections are run to shape, and two are semicircular arcs, and the middle is straight line, so that the bobbin winding volume that is matched with it is maximum. The hollow shaft 3 is formed by injection molding of plastics, and the thickness of the skin is 2mm. The transverse section of the bobbin body 4 is also in the shape of a racetrack, which coincides with the hollow shaft 3 and is a dynamic fit. The radius of the two semi-cylindrical winding surfaces is 30 times the radius of the optical fiber wire, and the diameter of the optical fiber wire with a diameter of 3mm should be 90mm. The front end disk 7 and the rear end disk 5 are also in the shape of a racetrack, and the design winding thickness is 15mm. The spool is made of plastic injection molding with a skin thickness of 2mm. The rest of the structure inherits the structure of the existi...

Abstract

The invention discloses an optical fiber storage box with a telescopic thread spool, and belongs to the technical field of optical fiber communication equipment. The optical fiber storage box with the telescopic thread spool consists of two parts, namely, the optical fiber storage box and a thread spool, wherein the optical fiber storage box consists of a box body, a hollow shaft and a falling door; the hollow shaft is fixedly arranged on the rear vertical surface of the box body by bolts; the falling door is hinged to the lower edge of the front surface of the box body, the falling door is fastened with the box body while being turned upwards, and the falling door is away from the box body while being turned downwards; the thread spool consists of a thread spool body, a front end disc and a rear end disc, and the thread spool penetrates through the hollow shaft. When optical fiber cables are stored or taken out, the box body can be pulled out to be operated, thus the operation can be clearly seen, hands can be put in place, the cable winding can be tidy and handy, and the optical fiber cables can not be damaged. The optical fiber storage box with the telescopic thread spool, disclosed by the invention, is used for winding and storing redundant parts of the optical fiber cables which are used for connecting two devices.

Description

technical field [0001] Optical fiber communication equipment. Background technique [0002] The storage box of existing optical fiber line is a hexahedron box, and two cantilever type spools protruding inward are set at the back of it. Wrap the redundant part of the fiber optic cable connecting the two devices on the spool in the box. The same spool needs to be wrapped with multiple fiber optic cables, stored in mixed packages, entangled and hung, and one of the multiple cables needs to be taken out during maintenance, which is very uncomfortable. convenient. There is a great need for an optical fiber line storage device that is stored orderly, does not hook up to each other, and is convenient for storage. Contents of the invention [0003] The technical problem to be solved by the fiber storage box with telescopic spool is: when accessing the optical fiber on the spool, the field of view is wide, the operation is convenient, and the access is convenient. The technical ...
