Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a heavy-duty type door hinge which characterized in that: the box door locking device comprises a fixed seat 2 arranged on a box body and a hinged arm 3 fixed on a box door, wherein a trigger 4 is hinged on the hinged arm 3, and the trigger 4 and the fixed seat 2 are detachably hung and buckled; fixing base 2 include connecting plate 21 and locate the curb plate 22 of its both sides, connecting plate 21 is the opening slot form rather than the curb plate 22 of both sides by the integrative bending of sheet metal, has seted up mounting groove 211 on the connecting plate 21, trigger 4 front end is provided with connecting seat 41, connecting seat 41 passes this mounting groove 211 and sets up the location rivet 1 between both sides board 22 and hangs the knot, realizes being connected between trigger 4 and fixing base 2.

The lower end face of the connecting seat 41 is provided with a clamping groove 42, and the clamping groove 42 is buckled on the notch of the mounting groove 211.

The upper end face of the connecting seat 41 is provided with a positioning groove 43, and the positioning groove 43 is hung and buckled on the positioning rivet 1.

The side plate 22 is provided with an inward-concave reinforced area 221, and the positioning rivet 1 is arranged in the reinforced area 221.

The side plate 22 is provided with an inward-bent supporting column 222, and an end face of the supporting column 222 is supported on an inner end face of the other side plate 22.

The trigger 4 is also hinged with a limiting piece 44, and the limiting piece 44 is positioned at two sides of the trigger.

The working principle is as follows: the door hinge in the present case includes the fixing base of installing on the box and fixes the hinge arm on the chamber door, and the articulated trigger of installing on the hinge arm, trigger and the detachable installation of hanging of fixing base are detained.
