Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the present invention to be described.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of refrigerator doors opening device, it comprises housing 1, and the inner chamber of housing 1 is provided with push rod 2, depression bar 3 and slideway 4; One end of depression bar 3 is fixed in housing 1, and the upper surface of depression bar 3 is provided with holding section 31; Push rod 2 is slidedly arranged on slideway 4, and the outer surface of push rod 2 is provided with first step portion 21; Be folded with the first elastomeric element 22 between first step portion 21 and housing 1, this first elastomeric element can be spring; Be folded with the second elastomeric element 32 between the lower surface of depression bar 3 and housing 1, this second elastomeric element also can be spring; Push rod 2 is positioned at the top of holding section 31; When the first elastomeric element 22 is in compressive state, holding section 31 is connected in first step portion 21 and stops push rod 2 to slide along slideway 4; When holding section 31 to move down with depression bar 3 and leave first step portion 21 time, push rod 2 slides along slideway 4 and stretches out housing 1 under the first elastomeric element 22 promotes.
Refrigerator comprises the casing 52 of refrigerator doors 51 and refrigerator.This refrigerator doors opening device 60 is fixedly arranged on the lower end of refrigerator doors 51, by screw by housing and refrigerator doors affixed.When refrigerator is in closed condition, refrigerator doors 51 closes in casing 52.First elastomeric element 22 is in stressed impaction state, and the second elastomeric element 32 pairs depression bar 3 and holding section 31 produce elastic force upwards, and first step portion 21 stops by holding section 31 and remains static, and now push rod 2 is in locking state.Because push rod 2 is positioned at slideway 4 and housing 1, therefore, do not affect the closedown of refrigerator doors.
When opening the door, gently jam on bar 3 with pin, holding section 31 moves down with depression bar 3 and leaves first step portion 21, and the locking state of push rod 2 is removed.Push rod 2 is under the elastic force effect of the first elastomeric element 22, moves in the casing direction along slideway 4 to refrigerator.Push rod 2 forces in casing, thus pushes refrigerator doors open, refrigerator doors is opened.
When refrigerator doors is closed, push rod 2 heads on casing, interacts with casing, and push rod 2 slides towards the direction of the first elastomeric element 22 and compresses the first elastomeric element 22.When above first step portion 21 moves to holding section 31, the second elastomeric element 32 pairs depression bar 3 produces thrust, and depression bar 3 drives holding section 31 to move up, thus with first step portion 21 clamping, push rod 2 comes back to locking state.In this process, the second elastomeric element 32 plays the effect of stepping down, resetting.
Use device of the present invention, in the occupied situation of both hands, by foot-operated depression bar, the rapid unlatching of refrigerator doors can be realized, have save time, the advantage of economize energy; The present invention can realize the semi-automation that refrigerator doors is opened, and has laborsaving, advantage easily.
On said structure basis, as shown in Figure 3, depression bar 3 can comprise cantilever portion 33 and stampeding section 34, and one end of cantilever portion 33 is fixed in housing 1, and the other end is connected with stampeding section 34.The stampeding section of this vibrational power flow, is convenient to user and tramples, and easily opens refrigerator doors with pin.
As shown in Figure 3, the outer surface of push rod 2 can also be provided with second step portion 23, and slideway 4 is provided with protuberance 41, when the first elastomeric element 22 promote push rod 2 slide along slideway 4 time, protuberance 41 is by sliding to stop push rod 2 with the clamping in second step portion 23.In refrigerator doors opening process, second step portion coordinates with protuberance, can play spacing effect to push rod, the elastic force because of the first elastomeric element can be prevented excessive and make push rod entirety skid off housing.
Push rod and slideway can have various shape.Push rod 2 can be cylindric, and first step portion 21 and second step portion 23 can be all annular projection; Slideway 4 can be rectangular tube.Push rod is cylindric, can reduce sliding friction, is easy to slide.Slideway is rectangular tube, has the advantage being easy to manufacture.
A kind of refrigerator, it comprises casing 52 and refrigerator doors 51, and it also comprises foregoing refrigerator doors opening device 60, and refrigerator doors opening device 60 is fixed in the lower end of refrigerator doors 51.When using this refrigerator, in the occupied situation of both hands, user by foot-operated depression bar, can realize the rapid unlatching of refrigerator doors, have save time, the advantage of economize energy; Realize the semi-automation that refrigerator doors is opened, there is laborsaving, advantage easily.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that this only illustrates, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection scope of the present invention.
