Specific embodiment

Specific further instruction is made to the utility model with reference to the accompanying drawing.A kind of side opening door hinge of band damping, Be characterized in that: it includes fixed hinge seat 1 and hinges seat 2, and flap 11 is outward extended on fixed hinge seat 1, described Hinges seat in be provided with damper 3, the damper rod 31 of damper 3 is contacted in flap 11 with being arranged, and is played to hinge Buffer function when closing.

Directive wheel 4 is also equipped with by elastic parts in the hinges seat 2, directive wheel 4 is pushed away elastic parts It is contacted under dynamic with the guide surface 12 being arranged on flap 11, and in hinge opening and closing, directive wheel 4 is located on guide surface 12 sliding It is dynamic, the reset groove 13 being recessed inwardly is provided on the guide surface 12, when hinge is closed, directive wheel 4 slides recessed into reset In slot 13.

The elastic parts includes that shift fork 5 and the mounting base 51 set on 5 front end of shift fork, directive wheel 4 are mounted on mounting base In 51, pilot hole 21 is provided in the hinges seat 2,5 rear end of shift fork is interspersed in pilot hole 21, and 5 front end of shift fork is set It is equipped in the guide groove 53 that guiding axis 52 is interspersed on hinges seat.

5 surface of shift fork is additionally provided with spring 54, and 54 one end of spring presses against on pilot hole 21, and the other end presses against In mounting base 51, spring 54 pushes directive wheel 4 to move always to 12 direction of guide surface.

Working principle: as shown in figures 1 to 6, being mounted on refrigerator for use by this hinge in this case and be illustrated, hinge First embodiment be fixed hinge seat and hinges seat is separate structure.Fixed hinge seat is mounted on cabinet 6, and movable Hinge seat is fixed on chamber door 61.It is outward extended with flap on fixed hinge seat, hinged shaft 6 is provided on flap and is interspersed in chamber door Upper and its hinge.When door opening or closing, chamber door is rotated by the center of circle of hinged shaft, realizes shutter door function.

It as is seen in figs 7-10, is this case schematic structural diagram of the second embodiment, in the structure, fixed hinge seat and moveable hinge Chain seat is structure as a whole, and the top of flap is provided with hinged shaft 6, hinged shaft 6 and the hinge hole 61 being arranged on hinges seat Hingedly, when hinge is opened and closed, hinges seat is rotated by the center of circle of hinged shaft, realizes shutter door function.

For chamber door in moving process, spring pushes directive wheel to move always to guide surface direction, leads so that directive wheel is located at It is slided to face surface.After chamber door is closed to certain angle, directive wheel slides in reset groove from guide surface.Directive wheel into Enter during resetting groove, directive wheel and reset groove interaction generate the thrust of shutdown, so that refrigerator doors are closed automatically It closes.And after refrigerator doors are closed, directive wheel holding is resetting in groove, generates the pressure of shutdown, enables refrigerator doors close It closes, avoids leaking.

Further: excessive velocities when being automatically closed in order to avoid refrigerator doors cause refrigerator doors to hit with refrigerator body And noise is generated, damper, damper rod top and the fixed hinge seat of damper are additionally provided in this case in hinges seat Buffer function when closing to chamber door is played in contact.And after refrigerator doors are opened, the effect of damper rod reset spring inside it Under, it automatically resets, prepares to reset next time.Therefore compared with traditional technology, this refrigerator has automatic buffer closing function, While guaranteeing refrigerator airtight performance, operation sense is promoted, therefore can be widely used to promote.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.
