Description
Technical field
The present invention relates to a kind of hinge means, 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 needs to automatically reset under certain torsion after opening, and namely closes.Be connected by door-hinge between current glass door with cabinet (outer frame body), after installation, door-hinge is relative motionless with cabinet (outer frame body), glass door is rotate relative to door-hinge, rod-type torsion spring is provided with between door-hinge and glass door, 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 the elastic force overcoming torsion spring, and when loosing one's grip, under the effect of torsion spring, glass door can be closed automatically, without the need to operating personnel people for closing the door.During 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, namely not energy-conservation; Pretightning force is large, and to there will be impact force at closing time excessive, and cause repeatedly resilience, and cold draining number of times also can be caused too much.Need there is a rotation displacement (angular displacement) to door-hinge relative to cabinet during assembling refrigerator door, when door-hinge is often turned an angle, the pretightning force of torsion spring will change, when rotating door-hinge and making the pretightning force of torsion spring reach perfect condition, door-hinge can be fixed, now, unlatching freezer French casement and glass door automatically reset to close and reach perfect condition simultaneously.Artificial adjustment at present bothers very much, wastes time and energy.The minimum angular displacement often adjusted in currently available technology is once 30 °.
Summary of the invention
The object of this invention is to provide a kind ofly to adjust precisely, structure is simple, easy to adjust, time saving and energy saving, the freezer French casement adjustable hinge device of increasing work efficiency, and overcomes the deficiencies in the prior art.
Freezer French casement adjustable hinge device of the present invention, comprise substrate, substrate is provided with fixing hole and notch wheel regulating mechanism are installed, the concrete structure of described notch wheel regulating mechanism is as follows: on substrate, be provided with ratchet hole, the side in ratchet hole is provided with side channel, ratchet is positioned at described ratchet hole, the locating part that restriction ratchet moves axially in ratchet hole is provided with between substrate and ratchet, ratchet is provided with in described side channel, one end of ratchet is provided with spring, ratchet is pushed to one end of side channel under the action of the spring, ratchet on ratchet is meshed with the side tooth outside ratchet, the inner bore perimeter of described ratchet has the interior tooth axially arranged.
Freezer French casement adjustable hinge device of the present invention, wherein said side channel is crescent shape, and there is projection the termination of described ratchet, and described spring tip is sleeved on described projection; In the stomidium that the other end of described spring inserts side channel end or be fixedly connected with side channel end, described being fixedly connected with comprises on steady pin that is bonding or that be sleeved on side channel end or screw is fixedly connected with.
Freezer French casement adjustable hinge device of the present invention, wherein said locating part is circlip, and the outside of this circlip is just placed in the draw-in groove on the inner side edge of ratchet hole, and the inner side of this circlip is just placed in the side channel outside ratchet; Described interior tooth is circumferentially equally distributed fin structure.
Freezer French casement adjustable hinge device of the present invention, during installation, substrate is fixed on freezer French casement exterior door frame or cabinet base place by installing hole, with hinge door-hinge (outer-hexagonal) lower end of glass door insert ratchet in this hinge means endoporus and by there being tooth in bihexagonal mutually to insert, ratchet is positioned at one end of side channel under the action of the spring, ratchet on ratchet is meshed with the side tooth outside ratchet, make ratchet can only one-directional rotation, the door-hinge namely inserting ratchet endoporus be thereupon only unidirectional rotatable.As Fig. 1: when adjusting the pretightning force of rod-type torsion spring between door-hinge and glass door, can only rotate by clockwise direction, namely only need rotate to Compress Spring direction, when clockwise direction rotates door-hinge, ratchet rotates thereupon, ratchet drives ratchet Compress Spring simultaneously, ratchet and ratchet produce relative side set slippage, torsion spring pretightning force between door-hinge and glass door is increased, according to required pretightning force, door-hinge can be rotated continuously, when pretightning force reaches perfect condition, door-hinge can be fixed, ratchet is leaned the one end in side channel under the action of the spring, and with ratchet, to engage each other geo-stationary motionless.Adjustment process is very precisely, conveniently, time saving and energy saving, improves operating efficiency, and the pretightning force of torsion spring controls precisely, and the minimum angular displacement often adjusted once is 6 °, because Adjustment precision is high, cold draining amount is reduced greatly, more energy-conservation.
