Thus, the utility model has the advantages of simple structure and convenient operation.

Description

Can move the understructure of formula household electric appliance

The utility model relates to a kind of household electric appliance base, especially refers to the washing machine pedestal structure that operational vibration is bigger.

At present, many household electric appliance, as: washing machine, refrigerator, even also comprise some furniture, and as: cabinet for television set and other table, cabinet need to move the position sometimes, therefore, someone is household electric appliance, as: washing machine, the fastening foot of base changes roller into, but, because of the roller poor stability, when washing machine is worked, can cause vibration and noise all to increase; The people is also arranged, and setting can upper and lower flexible roller on each fastening foot (being generally 4) of base next door or it in, with satisfied requirement of moving and fixing stability, still, and complex structure, troublesome poeration, applicability is relatively poor.

The purpose of this utility model provides a kind of understructure that moves the formula household electric appliance, in the symmetry center of each fastening foot of base, the rolling wheel frame with elastic clip control is set, and makes roller play support effect or quick condition.

The purpose of this utility model is achieved in that it comprises four jiaos fastening foot 2 of base 1 and bottom thereof, be provided with a fixed cover 11 in the middle of base 1 bottom and bottom one side is provided with cantilevered axle 12, in the fixed cover 11 of base 1, be provided with and go up, the central roller frame 3 that lower slider cooperates, on this central roller frame 3, be provided with two relative two side holes 32, on the fixed cover 11 of base 1, be provided with two side through hole 113 corresponding with above-mentioned two side holes 32 and that diameter is identical again, outside the fixed cover 11 of base 1, place and be provided with the elastic clip 4 that the locating stud 44 with its chuck place matches with two side through hole 113 of fixed cover 11.

Two jig arm 42 of above-mentioned elastic clip 4 are provided with a chain of elastic clip 5 of its chuck connection elastic clip 4 folder handles and should chain of rings elastic clip 5 be articulated in slidably on the above-mentioned lower cantalever axle 12.

Owing to adopt such scheme: simple in structure, operation is also convenient.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments schematic representation.

The A-A cross-sectional schematic of Fig. 2 the utility model exemplary embodiments Fig. 1.

Among the figure: 1, base (or housing), 11, fixed cover, 111, keyway, 112, through hole, 113, two side through hole, 12, the lower cantalever axle, 2, fastening foot, 3, central roller frame, 31, axial bond, 32, two side holes, 33, roller, 4, elastic clip, 41, axle 42, two jig arm, 421, pin-and-hole, 43, spring, 44, locating stud, 441, screw rod, 5, a chain of elastic clip, 51, the both sides bearing pin

Present embodiment mainly comprises base 1, a plurality of fastening foot 2, and central roller frame 3, elastic clip 4 and a chain of elastic clip 5, as Fig. 1, shown in 2, wherein:

Base 1 is the supporting base (mostly being rectangle greatly) that is connected the household electric appliance bottom, and its bottom center connects a fixed cover 11, also is provided with the cantilevered axle once 12 with adjustable upper and lower link stopper in addition at its one side place, bottom; Have axial keyway 111 (being separated by 180 ° for two) on fixed cover 11 endoporus, offer two identical side through hole 113 at the diameter of bore opposite position (being separated by 180 °) of these keyway 111 both sides again, and have a concentric through hole 112 on the diapire of fixed cover 11 endoporus.

Fastening foot 2 is connected four jiaos of bottoms (or in aggregates with base 1) of base 1, constitutes the fixed bearing to household electric appliance on the base 1.

Central roller frame 3 epimeres are provided with two axial bonds 31 that the keyway 111 with base 1 is slidingly matched, opposite position (being separated by 180 °) is offered two side holes 32 (identical with side through hole 113 diameters) on these axial bond 31 both sides diameters again, and the hypomere level is stretched out the action roller 33 (roller that substantially horizontal can be rotated arbitrarily) of a plurality of symmetries; This central roller frame 3 is arranged in the middle of base 1 below.

Elastic clip 4 is to make two jig arm, 42 inner edges be pressed in axle 41 outer rims with spring 43 two ends, the locating stud 44 that inwardly puts in and match with respective side through hole 113, side opening 32 is set respectively at the chuck place of two jig arm 42, these locating stud 44 pin heads are the sphere end, the centre has shoulder, afterbody is a screw rod 441, and be connected in the collet bore of elastic clip 4 with a nut and two spring washers, in addition, two jig arm 42 folder on have pin-and-hole 421.A chain of elastic clip 5 also is to make two arm inner edges be pressed in lower cantalever axle 12 outer rims (identical with elastic clip 4 structures) with both ends of the spring, and should chain of rings elastic clip 5 can on the lower cantalever axle 12 of base 1, slide, and the chuck inboard of its jig arm has 51 insertings of both sides bearing pin in jig arm 42 is pressed from both sides the pin-and-hole 421 of end, and folder that should chain of rings elastic clip 5 is exposing outside base 1 edge, so that push the folder handle of a chain of elastic clip 5, just can drive the clamping of elastic clip 4 or open with hand.Also can or unclamp (not shown) with the clamping of movement weight pulley mechanism controls elastic clip 4.

The operating process of present embodiment:

Make it throw off elastic clip 4 when opening a chain of elastic clip 5, and glide along lower cantalever axle 12, then, lift base 1 one sides, because central roller frame 3 is conducted oneself with dignity and is glided in fixed cover 11, two side through hole 113 on 32 secured in alignment of the two side holes on the central roller frame 3 cover 11, this moment, elastic clip 4 was under spring 43 effects own, the locating stud 44 at chuck place inserts in the two side holes 32 of central roller frame 3, and the roller 33 of central roller frame 3 is lower than fastening foot 2, therefore the household electric appliance on the roller 33 support bases 1 can promote on the ground easily.

When on move the folder handle that a chain of elastic clip 5 clamps elastic clip 4, make the locating stud 44 of elastic clip 4 chucks leave the two side holes 32 of central roller frame 3, fixed cover 11 relative central roller framves 3 fall, and fastening foot 2 is supported on the ground, roller 33 does not play supporting role, and is stable when making household electric appliance operation.
