Specific embodiment

Specific further instruction is made to the utility model with reference to the accompanying drawing.A kind of split type side enabling is lower to reset hinge Chain, it is characterised in that: it includes fixed hinge seat 2, and articulated slab 21 is outward extended on fixed hinge seat 2, is set on articulated slab 21 It is equipped with hinged shaft 22 to be interspersed on chamber door 11 with it hingedly, is additionally provided with buffer unit, buffer unit includes buffing pad 3, buffing pad 3 It is interior that directive wheel 5 is equipped with by elastic parts, directive wheel 5 under the promotion of elastic parts with the guiding that is arranged on articulated slab 21 Face 6 contacts, and when chamber door 11 is opened and closed, directive wheel 5, which is located on guide surface 6, to be slided, and is provided with and is concaved on the guide surface 6 Sunken reset groove 61, when chamber door 11 is closed, directive wheel 5 is slid in reset groove 61.

Mounting hole 31 is provided on the buffing pad 3, fixed screw passes through mounting hole 31 and chamber door 11 is fixedly mounted.

The guide surface 6 is arc-shaped, and is arranged by axle center of the circle center hole of hinged shaft 22.

The elastic parts includes that shift fork 7 and the mounting base 71 set on 7 front end of shift fork, directive wheel 5 are mounted on mounting base In 71, pilot hole 72 is provided in the buffing pad 3,7 rear end of shift fork is interspersed in pilot hole 72, and 7 front end of shift fork is provided with Guiding axis 73 is interspersed in the guide groove 74 on buffing pad 3.

7 surface of shift fork is additionally provided with spring 75, and 75 one end of spring presses against on pilot hole 72, and the other end presses against In mounting base 71, spring 75 pushes directive wheel 5 to move always to 6 direction of guide surface.

Buffer 8 is additionally provided in the buffing pad 3,81 top of buffer bar of buffer 8 connects with fixed hinge seat 2 Buffer function when closing to hinge is played in touching.

Working principle: being illustrated by taking refrigerator as an example in this case, it includes fixed hinge seat 2 for the hinge of this case, fixed hinge It is outward extended with articulated slab 21 on chain seat 2, hinged shaft 22 is provided on articulated slab 21 and is interspersed on chamber door 11 with it hingedly.Chamber door is opened When closing, chamber door 11 is that the center of circle is rotated with hinged shaft 22, realizes shutter door function.It is more steady when wherein, in order to enable door opening or closing It is fixed, operating noise is reduced, guarantees that the airtightness of chamber door, the hinge seat in this case are further equipped with buffer unit, when user needs to be somebody's turn to do When function, buffer unit is assembled with hinge seat and is used as an accessory.When assembly, it is only necessary to pass through position using fixed screw It is fixedly mounted in the mounting hole 31 on buffing pad with chamber door 11.

Chamber door 11 is in moving process, and spring pushes directive wheel to move always to guide surface direction, so that directive wheel is located at The sliding of guide surface surface.After chamber door is closed to certain angle, directive wheel slides in reset groove from guide surface.Directive wheel exists 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 1 And noise is generated, buffer, buffer bar top and the fixed hinge seated connection of buffer are also additionally provided in this case in buffing pad Buffer function when closing to chamber door is played in touching.And after refrigerator doors are opened, the effect of buffer bar 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.Meanwhile buffer unit and fixed hinge seat split production, only when When user needs to change function, buffer unit is assembled to using in equipment, to facilitate user according to the practical need of oneself It is selected, to be suitble to different places to use.Therefore it 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.
