The adjustable supporting device of household electric appliance and household electric appliance
[technical field]
The utility model relates to a kind of support device, refers in particular to a kind of adjustable supporting device of household electric appliance.
[background technique]
Household electric appliance, especially bulky and household electric appliance that weight is also very big are refrigerator or roller washing machine for example, has leg or roller that a huge casing and several bottoms that is arranged on casing are used for supporting box usually.In actual applications, concrete ground possibility out-of-flatness of placing these household electric appliance, making household electric appliance place unstable later on the ground and influence normally uses, so people have invented adjustable support device, thus this support device can be in limited scope on the short transverse up-down adjustment balance box.Yet because household electric appliance are placed in the corner in room usually, if this adjustable support device is arranged on the rear portion of casing, the user need move heavy casing just can regulate operation, and this not convenient people of being do not wish to see.
As improvement, a kind ofly can realize that the novel support device of the support device at casing rear portion being regulated operation is developed out from the front portion of casing, U. S. Patent the 4th, 789 No. 121 and the 4th, 955, has all disclosed this support device No. 569.This adjustable support device comprises the adjusting axle that extends to the rear portion of casing from the front portion of casing, and the supporting member that is arranged on the casing rear portion, rotating this conciliation axle can drive this supporting member and come back rotation with respect to casing, thereby make the roller of supporting member end on the short transverse of casing, produce displacement up and down, realize the height of the roller at the rear portion of casing being regulated from the front portion of casing.Then, the defective of this design is: adjusting axle be one from the front portion of casing the horizontally extending elongated axis body to the rear portion, there is query in the rotation whether intensity of himself can provide enough power to drive supporting member.

[embodiment]
With reference to figure 1, the adjustable supporting device 2 of a kind of mode of execution of the present utility model is installed in the bottom of refrigerator.This refrigerator comprises a door body that has the casing 1 of inner accepting space and be used to seal this inner accepting space.The roller that has four supporting box on the bottom surface of casing 1, adjustable supporting device 2 are installed on the bottom of casing 1 and are connected its structure subsequent detailed description with a roller at the rear portion, bottom surface of casing 1.Certainly, except the refrigerator of Fig. 1, adjustable supporting device 2 of the present utility model also can be installed on other household electric appliance, for example refrigerator or roller washing machine.
With reference to figure 2 and Fig. 3 A to Fig. 3 C, adjustable supporting device 2 is installed on the base plate 10 of bottom surface of casing 1, and it comprises three primary components: regulating element 3, supporting member 4, and reinforcing element 5.Regulating element 3 is the adjusting axles that extend to the rear portion from the front portion of casing 1 bottom, and adjusting axle comprises with respect to the bottom surface of the casing front end 31 that extends back of level and the rear end 32 that is tilted to bending extension with respect to front end 31 substantially.The end of front end 31 has one and regulates head, and the operator can insert this adjusting head and rotate this instrument with instruments such as hexagon wrenchs, thereby the front end 31 and the rear end 32 that drive adjusting axle rotate together.The end that the rear end 32 of adjusting axle extends through reinforcing element 5 and supporting member 4 links together, and 32 end forms outside thread 33 in the rear end.Supporting member 4 is pivotally connected on the base plate 10 by the pivot 41 that is arranged in the opening on the base plate 10, and it comprises the joint 40 and the supporting portion 42 that is positioned at the below of base plate 10 of the top of the base plate 10 that is positioned at casing 1.The end of joint 40 has butt joint 44, offers a through hole with internal thread in the butt joint 44, and the internal thread in the through hole of butt joint 44 matches with outside thread 33 on the rear end of adjusting axle 32.The end of supporting portion 42 is connecting roller 43.Reinforcing element 5 comprises the fixing part 50 that is fixed on the base plate 10 and from fixing part 50 upwardly extending reinforcing parts 51, reinforcing part 51 comprises the upstanding wall of two spaces and the angled end wall 52 that connects upstanding wall, on angled end wall 52, form opening (not indicating among the figure), the rear end 32 of adjusting axle extends through this opening and is connected on the supporting member 4, this angled end wall 52 is also supporting the rear end 32 of adjusting axle simultaneously, prevents its excessively displacement or distortion.The below of reinforcing part 51 has an opening on base plate 10, roller 43 can partly pass the top that this opening reaches base plate 10.
Working procedure below with reference to Fig. 3 A to Fig. 3 C explanation adjustable supporting device 2.Adjustable supporting device 2 mediates among Fig. 3 A, outside thread 33 on the rear end 32 of adjusting axle passes through hole in the butt joint 44 and the joint 40 of supporting member 4 links together, this moment, joint 40 was in vertical position substantially with respect to base plate 10 and supporting portion 42 is horizontal substantially with respect to base plate 10, and roller 43 parts are passed the top that opening on the base plate 10 reaches base plate 10.With reference to figure 3B, when the user need regulate the position of roller 33 downwards with respect to base plate 10, the user rotates adjusting axle by instrument, internal thread engagement in the outside thread 33 on the rear end 32 of adjusting axle and the through hole of the butt joint 44 on the supporting member 4 is rotated, make butt joint 44 downward-sloping mobile along the rear end 32 of adjusting axle, thereby driving supporting member 4 rotates counterclockwise with respect to base plate 10 along pivot 41, make the roller 43 of supporting portion 42 ends produce downward displacement with respect to base plate 10 on short transverse, roller 43 downward maximum displacements can reach 10mm in the present embodiment.With reference to figure 3C, when the user need be with the position of roller 33 with respect to base plate 10 during to adjusted, the user rotates adjusting axle by instrument, internal thread engagement in the outside thread 33 on the rear end 32 of adjusting axle and the through hole of the butt joint 44 on the supporting member 4 is rotated, make butt joint 44 be inclined upwardly mobile along the rear end 32 of adjusting axle, thereby driving supporting member 4 clockwise rotates with respect to base plate 10 along pivot 41, make the roller 43 of supporting portion 42 ends produce displacement upwards with respect to base plate 10 on short transverse, roller 43 downward maximum displacements can reach 5mm in the present embodiment.From Fig. 3 A to Fig. 3 C as can be seen, when roller 43 is in diverse location, the rear end 32 of adjusting axle is with respect to the inclined degree difference of its front end 31, for there are enough activity spaces the rear end 32 that guarantees adjusting axle, opening size on the angled end wall 52 of reinforcing element 5 should be than the diameter of adjusting axle rear end 33 more greatly, and the periphery of opening can it supports invigoration effects to adjusting axle rear end 33 simultaneously.
More than be a kind of better embodiment of the present utility model, it is pointed out that those of ordinary skill in the art can make rational adjustment to the utility model according to concrete needs under the prerequisite of not paying creative work.For example, the outside thread on the rear end of adjusting axle and the position of the internal thread in the butt joint can exchange, and be about on the rear end that female through hole is arranged on adjusting axle, and outside thread is arranged in the butt joint.These are reasonably changed and adjust all should be within the protection domain of claim of the present utility model.
