Description

The household electric refrigerator power assisting device that opens the door

The utility model discloses a kind of household electric refrigerator power assisting device that opens the door.

At present, domestic household electric refrigerator industry is developed energy-saving serial refrigerator unexpectedly mutually to attract the consumer.Thereby strengthen the air-tightness of gasket by the suction that increases gasket, reach the purpose of refrigerator energy-saving by reducing leaking of cold air.Technique scheme is the method that each producer generally adopts, but the problem of thereupon bringing is refrigerator doors and refrigerator doorframe inhale tension, thereby cause the difficulty of opening the door, particularly at overcast and rainy wet weather, contradiction is particularly outstanding.In addition, along with the continuous increase of refrigerator volume, refrigerator doors also increases thereupon, and there is the problem of the difficulty of opening the door too in the unlatching of refrigerator doors.

Thereby to be design a kind of by servomechanism with refrigerator doors and the favourable refrigerator that opens the door of the refrigerator doorframe local detachment power assisting device that opens the door for the purpose of this utility model.

For achieving the above object, the technical solution adopted in the utility model is: the household electric refrigerator power assisting device that opens the door, it is characterized in that: door position, the limit hinged one rotating handle of refrigerator doors, one end of push rod is hinged on handle, the other end stretches to and near refrigerator doorframe from the side of sealing magnetic stripe, and push rod is made the stretching motion perpendicular to the refrigerator doorframe front.

As shown from the above technical solution, use the hand pulling handle, the push rod that is connected on it supports the front of refrigerator doorframe, and refrigerator doors and refrigerator doorframe part strutted, even if under the situation that the suction-combining force is bigger between gasket and the refrigerator doorframe, the utility model still can be finished the action of opening the door more effortlessly, and the gasket adhesive is tight, the interior cold of case leaks less but chamber door is opened the problem of difficulty thereby solved.

The utility model will be further described below in conjunction with drawings and Examples.

Embodiment

Referring to Fig. 1,2,3,4, door position, the limit hinged one rotating handle 20 of refrigerator doors 10, one end of push rod 50 is hinged on handle 20, the other end stretches to and near refrigerator doorframe from the outside of sealing magnetic stripe 80, when being meant sealing magnetic stripe 80 with the doorframe adhesive near refrigerator doorframe herein, the front end of push rod 50 should not arrive to door body, in order to avoid the normal adhesive sealing of influence sealing magnetic stripe 80, and when handle 20 rotated, the front end of push rod 50 pushed up and doorframe at once.

Referring to Fig. 3,4, the door position, limit of refrigerator doors 10 is provided with leader's seat 30, be that a cross section is roughly L shaped cavity in the handle base 30, its open-mouth is positioned at refrigerator doors 10 outer surfaces one side, handle 20 and support 40 are hinged and constitute and be rotatably assorted by the rotating shaft 60 that is parallel to 10 limits of refrigerator doors, rotating shaft 60 is provided with a back-moving spring 70, its two ends are resisted against respectively on handle 20 and the support 40, the cross section of support 40 is roughly L shaped, so support 40 just can seat crouches in the L shaped cavity in handle base 30 and is connected with it.Earlier that handle 20 and support 40 usefulness rotating shafts 60 are hinged during assembling, again handle base 30 is connected with support 40 usefulness screws.

One position of the confession holds on the handle 20 is positioned at localized indentation 11 places that offer on the refrigerator doors 10, rotating shaft 60 is positioned on the bracing strut set on handle 20 and the support 40 21,41, be provided with

catch

22,31 at described handle base 30 and handle 20 near above-mentioned recess 11 places, catch 22,31 toward each other and block face in same plane, rotating shaft 60 roughly is positioned at handle about 20 positions placed in the middle, the cross section of push rod 50 is an elongated rectangular, be that push rod 50 selects for use flat plate to be processed into, to increase the contact area between itself and doorframe, the end of push rod 50 is arranged with a protective jacket 51.

In the opening process of door; hand stretches between above-mentioned recess 11 and handle 20 inboards, so that move handle 20, the setting of

catch

22,31 has limited hand effectively and entered too far in it; thereby unlikely hand touches work packages such as spring 70; in order to avoid injured, the end of push rod 50 is provided with a protective jacket 51, and protective jacket 51 can be selected materials such as plastics, rubber for use; should avoid selecting for use the rigidity hard material; when opening door, push rod 50 all will add protective jacket 51 and can protect doorframe to bumping doorframe at every turn.

The anterior shaft of push rod 50 is positioned at the outside of the sealing magnetic stripe 80 on the refrigerator doors 10, passes the pilot hole that is provided with on handle base 30 and the support 40 successively, and the position for the hand gripping on the hinging supporting shaft 52 of push rod 50 and the handle 20 lays respectively at the left and right sides of rotating shaft 60.The hinging supporting shaft 52 of push rod 50 be positioned on the handle 20 when it rotates to the close position of refrigerator doorframe, be that the position that the hinging supporting shaft 52 of push rod 50 is positioned on the handle 20 should be satisfied when handle 20 rotates, the axle core of hinging supporting shaft 52 is close to refrigerator doorframe one side, close hinging supporting shaft 52 positions on the push rod 50 are bending, its opening points to refrigerator doors 10 outsides, shown in Fig. 3,4,5, can avoid the limit portion of its arc when upset handle 20 and the shaft of push rod 50 to interfere like this.

Below in conjunction with accompanying drawing 2,3,4 duty of the present utility model is described:

The power of staff is applied to upset and makes its 60 clockwise directions rotation around the shaft on the handle 20 when opening the door, and is fixed on push rod 50 on the handle 20 this moment when self hinging supporting shaft 52 rotates, stretches out forward and door is backed down along the pilot hole in the handle base 30.In upset handle 20 rotary courses, the spring 70 that is set in the rotating shaft 60 is simultaneously stressed, and when unclamping handle 20, the elastic force that spring 70 is laid in resets it.
