Description

Freezer French casement adjustable hinge device

Technical field

The utility model relates to a kind of hinge means, and particularly a kind of freezer French casement adjustable hinge device, is arranged on freezer French casement hinge door-hinge, is the device for adjusting glass door screen resilience.

Background technology

Refrigerator is the capital equipment of conventional storage food. Refrigerator in application, glass door need to automatically reset after opening under certain torsion, closes. Between glass door and cabinet (outer frame body), be connected by door-hinge at present, after installation, door-hinge is relative motionless with cabinet (outer frame body), glass door is to rotate with respect to door-hinge, between door-hinge and glass door, be provided with rod-type torsion spring, one end of torsion spring is fixedly connected on door-hinge, and the other end is fixed on glass door. When operating personnel open the door, glass door rotates and has overcome the elastic force of torsion spring, and while loosing one's grip, under the effect of torsion spring, glass door can be closed automatically, without operating personnel people for closing the door. When installation, the pretightning force of torsion spring is extremely important, and pretightning force is little, and after loosing one's grip, glass door is not closed completely, and it is not closed completely and causes cold draining, and energy consumption is excessive, not energy-conservation; Pretightning force is large there will be impulsive force excessive at closing time, and causes repeatedly resilience, also can cause cold draining number of times too much. When assembling refrigerator door, need to there is a rotation displacement (angular displacement) with respect to cabinet to door-hinge, when door-hinge is often turned an angle, the pretightning force of torsion spring will change, in the time that rotation door-hinge makes the pretightning force of torsion spring reach perfect condition, can fix door-hinge, now, unlatching freezer French casement and glass door automatically reset to close and reach perfect condition simultaneously. The artificial very trouble of adjusting, wastes time and energy at present. In currently available technology, every adjustment minimum angular displacement is once 30 °.
