Specific embodiment
Specific further instruction is made to the utility model with reference to the accompanying drawing.A kind of split type side resets hinge on opening the door
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 the avoiding hollow groove that articulated slab inside hinged with it in the hinged seat that hinged shaft 22 is interspersed on chamber door 11, described is provided with indent
23, it is additionally provided with buffer unit, buffer unit includes buffing pad 3, and buffing pad 3 is interior to be equipped with directive wheel 5 by elastic parts, is led
It is contacted under the promotion of elastic parts with the guide surface 6 being arranged on articulated slab 21 to wheel 5, and when chamber door 11 is opened and closed, guiding
Wheel 5, which is located on guide surface 6, to be slided, and the reset groove 61 being recessed inwardly is provided on the guide surface 6 and is led when hinge is closed
It is slid in reset groove 61 to wheel 5.
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 avoiding hollow groove 23 is in indent arc-shaped.
The guide surface 6 is arc-shaped.
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: it is illustrated by taking refrigerator as an example in this case, wherein this hinge is upper hinge, therefore using concealed
Design, ensure that the beauty of 1 shape of cabinet.Wherein, concealed design is so that hinges must be fitted to inside chamber door 11,
Therefore when chamber door 11 is closed, chamber door has the activity trajectory of part-structure and the position of articulated slab to coincide, in view of this, in this case
Articulated slab using crotch design, the inside of articulated slab 21 is provided with the avoiding hollow groove 23 of indent so that chamber door open when, chamber door
Part-structure enters in avoiding hollow groove, and the two is avoided to conflict.
The hinge of this case includes the fixed hinge seat being fixed on cabinet, is outward extended with articulated slab on fixed hinge seat,
It is provided on articulated slab hinged with it in the hinged seat that hinged shaft is interspersed on chamber door.When door opening or closing, hinged seat in chamber door with
Hinged shaft is that the center of circle is rotated, and realizes shutter door function.It is more stable when wherein, in order to enable door opening or closing, operating noise is reduced,
Guaranteeing the airtightness of chamber door, the hinge in this case is further equipped with buffer unit, when user needs the function, buffer unit conduct
One accessory is used with hinge assemblies.When assembly, it is only necessary to the mounting hole and case being placed through using fixed screw on buffing pad
Door is fixedly mounted.
For hinge 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 hinge 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, buffer, the buffer bar top of buffer and fixed hinge are also additionally provided in this case in hinges seat
Seated connection touching, plays buffer function when closing to hinge.And after refrigerator doors are opened, the work of buffer bar reset spring inside it
It under, automatically resets, prepares to reset next time.Therefore compared with traditional technology, this refrigerator hinge is closed with automatic buffer
The effect of closing promotes operation sense while guaranteeing refrigerator airtight performance.In addition, buffer unit and hinge 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.
