The specific embodiment
As shown in Figure 2, the refrigerator shelf lowering or hoisting gear that provides by the utility model; Be that the take off and landing strip 4 that rack framework 2 usefulness pairings is provided with is suspended under the hangers 5 of two side of inner bag 1 of refrigerator, take off and landing strip 4 is stretched out from the side bottom surface of rack framework 2, be connected with the take off and landing strip adjusting device in being arranged on framework, in framework, also be provided with manual hoisting device, one end of take off and landing strip stretches out from the carriage that is arranged on the framework side, its other end is connected with the take off and landing strip adjusting device respectively, be provided with the total adjustable side that is connected with manual hoisting device in the adjusting device, the outside that a part of wheel rim of the regulating wheel 3 in the manual hoisting device stretches out edge before shelf framework 2; When about when stirring regulating wheel 3, it is flexible that the take off and landing strip adjusting device can drive take off and landing strip 4, thereby realize the lifting of rack.And when stopping to stir regulating wheel 3, under the gravity effect of rack and article thereof, the stop mechanism that is arranged in the lowering or hoisting gear plays the self-locking stopping function, and rack 2 will be fixed on selected any height and position.
Take off and landing strip adjusting device structure is shown in Fig. 3,4,5, and pulley 6 is walked around in the lower end of four take off and landing strip 4, by junction button 10, links to each other with four stay cords respectively; With stay cord walk around two groups be arranged on respectively the pairing take off and landing strip 4 link between first order assembly pulley 9 after, merge into one for per two.Walk around again be arranged on two groups of second level pulleys between the first order pulley after, stay cord is merged into a total stay cord 11 (total adjustable side) at last; Total stay cord 11 is connected with manual hoisting device; Side in framework is provided with compressing tablet 7 by screw, to pulley 6 and 4 position-limiting actions of take off and landing strip, prevents the take off and landing strip slippage; Equally, compressing tablet 8 also plays position-limiting action to pulley 9 and each stay cord, prevents that stay cord breaks away from.
The structure of manual hoisting device shown in Fig. 6,7, the fixed axis H that is provided with regulating wheel 3 (driving wheel), spring 12, rolling wheel 13 (follower) and is connected with rack 2; Around total stay cord 11, its internal circular surfaces is sleeved on the upper end of fixed axis H, and can rotate around fixed axis H on the outer round surface of passive rolling wheel 13.Spring 12 has two clamping termination F and G, and its internal diameter is more smaller than the external diameter of fixed axis H; Spring 12 is sleeved on the middle part of fixed axis H, and fixed axis H is had the certain power of holding tightly in advance and frictional force.3 lower ends that are sleeved on fixed axis H of regulating wheel, and can rotate around fixed axis H.At the middle part of the fixed axis H at spring 12 places, regulating wheel 3 has a semicircle ring wall 31 edges and is enclosed within the rolling wheel 13, and it is corresponding with semicircle ring wall 31 also to be provided with the protruding wall 131 of semicircular ring in the rolling wheel 13; Two clamping termination F of spring 12 and G are then between the circumferential space of two semicircle ring walls 31,131.
Manual hoisting device has lifting and locking function: no matter regulating wheel 3 forward or reverse all can drive rolling wheel 13 and rotate together, thus the lifting of realization rack; And regulating wheel 3 is when static, though rolling wheel 13 is just turning to or counter steer all by stop, thereby make rack stop at selected height and position.
The stop principle is as follows: when regulating wheel 3 forward or reverse, the circumferential end face of its semicircle ring wall all can withstand the clamping termination F or the G of spring 12; Make the internal diameter of spring 12 become big, spring disappears to the power of holding tightly and the frictional force of fixed axis H; So spring can rotate around fixed axis, and drive passive rolling wheel 13 by clamping termination F or G and rotate together.And when regulating wheel 3 was motionless, no matter rolling wheel 13 is made forward or reverse, the circumferential end face of the protruding wall of its semicircular ring all can withstand the clamping termination F or the G of spring 12; The internal diameter of spring 12 is dwindled, and spring 12 is further held fixed axis H tightly; The power big more power of then holding tightly in top is also big more; Under the frictional force effect, can not rotate because of producing self-locking between spring and the fixed axis; So the clamping termination F of spring or G have limited the rotation of rolling wheel 13 conversely.
In order to increase the frictional force between finger and regulating wheel 3 wheel rims, regulating wheel 3 can be processed into the groove shape along outer circumference surface.In addition, in order to reduce to stir the power of regulating wheel 3, the external diameter of regulating wheel 3 should be bigger than the external diameter of rolling wheel 13.
The utility model compared with prior art has the following advantages: (1) only need stir regulating wheel 3 to the left or to the right, just can realize the random lifting of rack 2, adapts to the needs of placing different big or small article.Operate easily easy.Adjustment process need not to take off rack and on article, time saving and energy saving; Reduce the time of opening the door, saved electricity consumption.(2) in a single day regulating wheel 3 stops to stir, and rack just stops at any height and position at place, has realized the height and position step-less adjustment of rack, can improve the inner space utilization rate of refrigerator to greatest extent.
