Description
Technical field
The utility model relates to a kind of refrigerator doors, particularly relates to a kind of self-locking refrigerator doors.
Background technology
Existing door body is after repeatedly closing use, and particularly the appliance door such as refrigerator is after Reusability, and the effect of its gasket descends, easily rebound after closing, because the active force between Men Tiyu electrical equipment main body descends, children easily open the door body, cause danger simultaneously.
Simultaneously, fix on the grip firmly because refrigerator doors need not one, all refrigerator doors can be opened in the optional position of gasket, so small children can open refrigerator doors easily, if mistake will ownly close in refrigerator, easy cause danger.
Summary of the invention
The utility model for current refrigerator without security consideration, small children can be opened refrigerator easily, produce dangerous problem, a kind of self-locking refrigerator doors is provided, has comprised refrigerator every body, be installed on the handle on a body, also include from lock set, describedly comprise that from lock set slot, plug, connecting rod and slip control piece thereof and back-moving spring and spring are spacing, described plug is fixed in the connecting rod top, and mates with slot; Described refrigerator body top protrusion forms slot and offers the basis; Described connecting rod is nested in the handle inboard slidably, and the spacing refrigerator every body that is fixed in of described spring, described back-moving spring are arranged between the spacing and connecting rod of spring bottom.
Utilize the slip control piece to produce active force to connecting rod in the middle of the utility model, force connecting rod to move downward, connecting rod coordinates with spring is spacing when moving downward, and produces the compression force to back-moving spring, thereby produces elastic deformation; After external force removed, back-moving spring, and drove plug and inserts in slot the connecting rod jack-up that makes progress due to the effect of elastic potential energy; Thereby realize locking and release between plug and slot.
Slot need to fixedly be opened on refrigerator body, offer the basis because the utility model discloses slot, that is to say that the one end is fixed on refrigerator body, an other end protrudes from refrigerator body, be arranged at the corresponding top of refrigerator doors, thereby guarantee the interference between plug and slot.
The slip control piece of connecting rod can adopt and can make its various control control mode and matching component thereof of moving downward, discloses especially two kinds of control pieces that preferably slide in the utility model, wherein,
First kind of way is: described slip control piece comprises that correspondence is formed at the engagement boss of handle bottom and connecting rod bottom.In this structure, mainly rely on boss intermeshing and dislocation, the boss here is mainly that the requirement field of conjugate action is the inclined-plane.Thereby when handle rotated, due to the dislocation between boss, thereby the compressing connecting rod moved downward, and then moved downward together with the plug that connects of drive and connecting rod, broke away from slot, realized release.After external force disappeared, back-moving spring produced thrust upwards to connecting rod, and and then form reverse rotatory force at field of conjugate action place, again plug is inserted slot, automatically lock refrigerator doors.
Simultaneously, rotate for convenient, the invention also discloses and include swing handle, described swing handle and handle are fixed, and form hand-held plane.
Thereby the increase focusing surface, handled easily.
The second way is: described slip control piece comprises the wedge that is fixed in the connecting rod outside, is provided with on handle corresponding to described wedge inclined-plane one side and presses button, describedly presses button and wedge inclined-plane interference.To pressing buttons force, press button along the inclined-plane application of force of wedge, and wedge is depressed, thereby force the connecting rod that is fixed together with wedge to move downward, and then move downward together with the plug that connects of drive and connecting rod, break away from slot, realize release.After external force disappeared, back-moving spring produced thrust upwards to connecting rod, and produced thrust by wedge to pressing button, will press button and return to original state, the refrigerator doors locking.
Simultaneously, as preferably the invention also discloses between described plug and connecting rod as being threaded.Thereby facilitate connecting rod to install.
Improve as another kind, the invention also discloses described plug is sphenocephaly.Thereby convenient plug is extracted from slot or is inserted, and increases the convenience of using.
In sum, after adopting technical scheme disclosed in the utility model, can not rebound after refrigerator doors is closed, simultaneously, can set as the case may be the height of pressing button and connecting rod position, thereby prevent that small children from opening the refrigerator doors release.
