Tray-type vertically-rotatable elbow

The invention solves the problem of providing a tray-type vertically-rotatable elbow. The tray-type vertically-rotatable elbow can be angle-adjusted to adjust the transmission direction of cables inside a bridge, and serving as a connecting angle-adjustable elbow, plays a vital important role on the integrated bridge. The tray-type vertically-rotatable elbow comprises an elbow body, one-way elbow units, two-way elbow units, an elbow bottom plate, an elbow fastener and an elbow baffle. The tray-type vertically-rotatable elbow is characterized in that the elbow body is formed through mutual fastening of the one-way elbow units and the two-way elbow units. The tray-type vertically-rotatable elbow has the advantages of solving the problem of redirection of the bridge on straight lines and being capable of being adjusted to an appropriate position in angle; the maximum bending angle between the one-way elbow unit and the two-way elbow unit is 90 degrees, so that a user can appropriately increase or decrease the numbers of the one-way elbow units and the two-way elbow units as required to adjust the angle of the tray-type vertically-rotatable elbow, thereby achieving local adjustment of the entire bridge.
