Description
Technical field
The utility model is disclosed to be a kind of door engine structure, more particularly is the door engine structure on a kind of household electrical appliance such as vertical refrigerator-freezer, refrigerator, chilled food showcase, disinfection cabinet.
Background technology
Combining and adopt pure door-hinge structure or hinge structure morely between the door on the household electrical appliance of mentioning in the above and the cabinet, opening and closing all need be finished by craft, and in use the inconvenience that is exposed is mainly reflected in the pass and closes.For example: after people get thing in the cabinet, close the door because of hand-held food hinders to take into account in time.Also have, in use, after especially child opens and takes, forget the situation of closing the door because of inadvertent and often occur.In view of this, people wish to have a kind of device that can close automatically that can make above-mentioned household electrical appliance after artificial the unlatching.
Summary of the invention
Task of the present utility model is will provide a kind of can implement the door engine structure of closing the cabinet door automatically.
Task of the present utility model is finished like this, and a kind of door engine structure comprises: an axle bed plate 7, on the plate body of this axle bed plate 7 between cloth be useful on screw hole 6, the cabinet pin screw hole 8 that is fixed on the cabinet; One is used for fixing the location-plate 3 in cabinet every frame, tool shaft hole 1, spring pin locating hole 2, screw 14; One is used to be set to the axle bed 9 on the cabinet door, and this axle bed 9 hangs down and is fixed in an end end of axle bed plate 7, tool spring pin locating hole 10; One rotating shaft 5, lower end are fixed on the axle bed 9, and the upper end then extends in described shaft hole 1; One spring 12 is placed in the rotating shaft 5, and two ends are formed with spring pin 4,11 respectively, and spring pin 4,11 is inserted in respectively in the described spring pin locating hole 2,10.
The utility model also has additional spring pin and adjusts hole 23 on described axle bed 9.
The utility model door engine structure is attached on the cabinet door and cabinet of household electrical appliance of vertical refrigerator-freezer, refrigerator, chilled food showcase etc., can automatically the cabinet door after opening be closed automatically.
Accompanying drawing and drawing explanation
Accompanying drawing is depicted as the utility model and is attached to the cabinet of refrigerator and a specific embodiment figure on the cabinet door.
The specific embodiment
Ask for an interview accompanying drawing, an axle bed plate 7 offers screw hole 6 and cabinet pin screw hole 8 on the plate body, through screw hole 6 and cabinet pin screw hole 8 bottom that axle bed plate 7 is secured to cabinet 17 is located respectively with screw 18 and cabinet pin 19.Cabinet door 21 shown in the figure is installed on the cabinet doorframe 13, the cabinet doorframe 13 general aluminium extruded profiled members that adopt, it has a cavity volume 22, and described location-plate 3 is located in this cavity volume 22, and sees through screw 16 until revolving and in the screw 14 that defaults in location-plate 3 sidepieces with hold-down screw 15.The shape of the cavity volume 22 on the cabinet doorframe 13 might not be the chamber shape shown in the figure, if the chamber shape of cavity volume 22 changes, the shape of location-plate 3 is also corresponding so changes thereupon, because location-plate 3 is positioned in the cavity volume 22 of cabinet doorframe 13 securely.Locating to offer an axle bed hole 20 on the cabinet of the bottom of cabinet door 21 and below corresponding to cavity volume 22, axle bed 9 places in this axle bed hole 20.The bottom of rotating shaft 5 is fixedly arranged on the axle bed 9, and rotating shaft 5 can also shape with axle bed 9 one certainly.After being set in spring 12 in the rotating shaft 5, the upper end of rotating shaft 5 being stretched in the shaft hole of putting on the location-plate 31, and the spring pin 4,11 at spring 12 two ends is planted in the corresponding spring pin locating hole 2,10.If will carry out appropriate regulation, also can realize by spring pin 11 being moved in the spring pin adjustment hole 23 to the torsion of spring 12.
At ordinary times, when cabinet door 21 is in closed condition, spring 12 only closes on the cabinet 17 cabinet door 21 with small pretightning force, and when cabinet door 21 was opened, spring 12 produced distortion or claims distortion, along with opening angle is bigger, distortion is then bigger, in case and user's hand or limbs leave the cabinet door 21 that is being opened, the previous distortion of spring 12 deorienting occurs and changes, and turns round in the process that the power that contracts disappears until cabinet door 21 is closed on the cabinet 17 at distortion power or title.
