Abstract

The utility model relates to a limit hinge which is mainly used for fixing double covers of a refrigerator. An outer hinge plate is provided with a stopper convex block, and an inner hinge plate is provided with a stopper lug boss. When the stopper convex block and the stopper lug boss are arranged on the position for limiting the rotary radian of the other hinge plate is larger than 90 DEG and less than 180 DEG when one hinge plate does not move. The hinge shortens and positions a switch stroke of the refrigerator, saves time and labor, and reduces the loss of refrigeration capacity.

Description

Limit hinge

The utility model relates to connector, especially for the double-canopy fixing hinge of household freezer.

At present, the double-canopy structure of the general employing of horizontal household freezer, tank wall crown center fixed hinge axle connects two lids with flap before and after household freezer, and each lid can hinge axis be that turnback is turned in the axle center and another lid is overlapping.Compare with single lid household freezer, flip firmly reduces half, and the lost aperture area of cold reduces half when getting thing.But, when needing both hands to get thing, a lid must be overlapped on another lid and could stablize, to uncap, close that cover stroke longer, time-consuming this moment, require great effort, the lost time of cold is longer, and it is many to lose cold.

The purpose of this utility model is to overcome with having the fixedly double-canopy defective of household freezer of hinge now, and the limit hinge that a kind of open and close lid stroke is short and can locate is provided.

Technical solution of the present utility model is: limit hinge, comprise on flap, hinge axis, the outer flap that stopping projection is arranged, and on the inner hinge plate stop ledge is arranged.Stopping projection, stop ledge are arranged on restriction when a flap is motionless, and the rotation radian of another flap is greater than the position of 90 degree less than 180 degree.There is bending at outer flap, inner hinge plate hinge place, limit two flap inwalls at grade and hinge axis the inner outside this plane, have screw fixed hole on the flap.

According to technique scheme, two longwell center fixed hinge axis at the household freezer top get final product flap with screw with lid is fixing.During use, raise the lid rotation and spend less than a certain position between 180 degree greater than 90, stopping projection on the outer flap and the stop ledge on the inner hinge plate are blocked the location at this moment.Make to cover to be less than 180 in upset and can to locate when spending, open and close lid stroke is short, saves time, laborsaving, cold scatters and disappears few.

Accompanying drawing 1 is looked schematic diagram for the utility model master;

Accompanying drawing 2 is the broken section vertical view of Fig. 1.

According to accompanying drawing, embodiment describes to the utility model.

Limit hinge comprises flap, hinge axis, on the outer flap 1 stopping projection 2 is arranged, and stop ledge 4 is arranged on the inner hinge plate 5; Stopping projection 2, stop ledge 4 are arranged on restriction when a flap is motionless, and the rotation radian of another flap is greater than the position of 90 degree less than 180 degree; Stopping projection 2, stop ledge 4 are arranged on restriction when a flap is motionless, and the rotation radian of another flap is 120 degree positions; There is bending at outer flap 1, inner plate 5 hinge places, limit two flap inwalls at grade and hinge axis 3 the inners outside this plane; On outer flap 1, the inner hinge plate 5 screw fixed hole 6 is arranged all.
