Locking device of box and optical fiber division box

Abstract

The invention discloses a locking device of a box, and the locking device can conveniently lock up a box body and a box cover. The locking device comprises the box body and the box cover which are fastened with each other, wherein, the box cover is equipped with a locking seat; a locking pin is movably inserted into the locking seat; the lower end of the locking pin is equipped with at least one clamp hook; the side wall of the box body is equipped with a locking hole seat; the locking hole seat is equipped with a pin hole matched with the locking pin; and the wall of the pin hole is equipped with a guide slot corresponding to the clamp hook. The invention further discloses an optical fiber division box which is provided with the locking device, an optical cable inlet and a rubber-insulated wire optical cable outlet, wherein the optical cable inlet and the rubber-insulated wire optical cable outlet are of an opening structure. The optical fiber division box is mainly used for accommodating an optical fiber connecting and forming device.

Description

technical field [0001] The invention relates to a locking device for a box and an optical fiber splitting box for splicing and terminating optical fibers. Background technique [0002] At present, the optical fiber distribution box used for placing optical fiber splicing and termination devices such as optical distribution trays or splicing trays has a structure including: a box body and a box cover that are articulated together, and the box body and the box cover are respectively provided with mutually cooperating The locking ring, the box body and the box cover are also provided with a flip cover and a flip seat that cooperate with each other, and an optical cable jack is provided on the side wall of the box body. When in use, after the box cover is closed, the flip cover needs to be pressed firmly on the flip cover seat, which is troublesome to lock. In addition, when installing an optical distribution tray or a fiber splicing tray, it is necessary to extend the optical ...

AI Technical Summary

Problems solved by technology

Because the fiber distribution box is usually placed outdoors, exposed to the sun and rain, it is very easy to age. After a period of use, the fiber distribution box needs to be replaced

At this time, it is necessary to take out the optical cable from the optical distribution tray or the splicing tray, and then reconnect it after replacing the fiber distribution box. Maintenance is very troublesome, and it will also cause communication interruption.
