Embodiment
With reference to the accompanying drawings, the leg assembly to household appliances of the present invention is elaborated.As a reference, in explanation of the present invention, be example with the roller washing machine, the leg assembly of household appliances is described.
Fig. 3 demonstrates the sectional arrangement drawing of leg assembly of the present invention.Fig. 4 demonstrates the oblique view of the suspension lid of Fig. 3.Fig. 5 demonstrates the oblique view of the caulking gum of Fig. 3.
As shown in the figure, leg assembly of the present invention includes following structure substantially: leg casing (CASE) 20, leg axle 30, suspension lid (SUSPENSION CAP) 40, sealing (PACKING) rubber 60 and compression spring 50.
Above-mentioned leg casing 20 is that periphery is circular hollow cylinder shape substantially, is arranged on the top on roller washing machine body chassis 10, is formed with combined hole 20a above the leg casing 20; Above-mentioned leg axle 30 is connected with the combined hole 20a of through hole 10a and above-mentioned leg casing 20 can carry out lifting, the bottom of leg axle 30 is formed with contact and is supported on the 30a of HEAD portion that ground rubber material is set, and above-mentioned through hole 10a is formed on a side on above-mentioned chassis 10; The combined hole 20a that above-mentioned suspension lid 40 surrounds above-mentioned leg casing 20 is provided with and forms, hang and to cover 40 central authorities and be formed with the lift span 40a that above-mentioned leg axle 30 is passed, when above-mentioned leg axle 30 carries out lifting, the inner peripheral surface of above-mentioned lift span 40a and the outer peripheral face of leg axle 30 are slided; Above-mentioned caulking gum 60 is arranged on the inside of above-mentioned suspension lid 40, and is formed with the rubbing hole 60a that above-mentioned leg axle 30 is slided; The upper end side of above-mentioned compression spring 50 is arranged on the above-mentioned suspension lid 40, its lower end side is arranged on the fixed part 30b, stretch along above-mentioned direction of displacement when the displacement of above-mentioned suspension lid 40, the fixed part 30b of above-mentioned disc-shape is formed on the outer peripheral face of above-mentioned leg axle 30.
Wherein, the bottom surfaces of above-mentioned suspension lid 40 therefrom mind-set the outside and is inclined upwardly gradually and forms the inclined plane, so when descending, being applied to a part that hangs in the elastic force that cover on 40 by above-mentioned compression spring 50, that above-mentioned suspension is covered is 40 recessed to the inside.
In addition, cover in 40 structures in above-mentioned suspension, both sides vis-a-vis are partly cut across formation slit (SLOT) 40b of portion along the length direction of lift span 40a, have to make above-mentioned suspension cover the recessed to the inside elasticity of 40 integral body.
On the one hand, being arranged on above-mentioned suspension covers in caulking gum 60 structures of 40 inside, the inner peripheral surface that makes the rubbing hole 60a that is formed on central authorities covers 40 lift span 40a side and exposes to hanging, and the inner peripheral surface of above-mentioned rubbing hole 60a and the outer peripheral face of above-mentioned leg axle 30 are slided.
Wherein, the inner peripheral surface of the rubbing hole 60a of above-mentioned caulking gum 60 is formed with a plurality of rubbing surfaces 61, and above-mentioned a plurality of rubbing surfaces 61 alongst form, and above-mentioned rubbing surface 61 is combined closely with leg axle 30 slide; As an example, 4 rubbing surfaces 61 of sum are formed on the position of above-mentioned rubbing hole 60a4 equal portions.
At this moment, the groove that is formed between above-mentioned rubbing surface 61 and the rubbing surface 61 is lubricant oil space (grease pocket) 62, and the lubricating oil on the above-mentioned lubricant oil space 62 can prevent when the relative motion of above-mentioned rubbing surface 61 and leg axle 30 because the wearing and tearing that friction causes.
Meanwhile, above-mentioned rubbing surface 61 tilts towards the lower end gradually laterally a little from the upper end of above-mentioned rubbing hole 60a, so can make the diameter of above-mentioned rubbing hole 60a lower end bigger a little than the upper end.
At this moment, the lower end of the rubbing surface 61 that joins with the bottom surface of above-mentioned caulking gum 60 forms curved surface 61a slowly towards the bottom surface side of above-mentioned caulking gum 60, can make the inflow of lubricating oil more smooth and easy.
That is to say that when above-mentioned rubbing surface 61 and 30 relative motions of leg axle, lubricating oil flow in the rubbing hole 60a by the curved surface of above-mentioned rubbing surface 61, then to the lubricant oil spatial movement.
On the one hand, leg assembly of the present invention with said structure can only be arranged on the drift angle in four drift angles on body chassis 10 of cylinder casing, also can be arranged on two drift angles of front face side or two drift angles of back side or two drift angles, and can all be arranged on four drift angles with mutual diagonal symmetry.
At this moment, in the drift angle side the invention described above leg assembly is not installed and the leg assembly of prior art is installed.
Below, the effect of leg assembly of the present invention with said structure is elaborated.
If the rotation owing to cylinder (not demonstrating in the accompanying drawing) when the washing of carrying out roller washing machine and dehydration produces vibration, body chassis 10 and the leg casing 20 of then above-mentioned vibration by above-mentioned roller washing machine is delivered to hang and cover on 40, at this moment carries out corresponding lifting along with corresponding extent of vibration makes above-mentioned suspension cover 40 peripheral parts along leg axle 30.
At this moment, force of sliding friction between the outer peripheral face of the rubbing surface 61 that makes the lift span 40a inner peripheral surface that acts on above-mentioned suspension lid 40 and caulking gum 60 and above-mentioned leg axle 30 and the elastic force that compresses spring 50 play the effect of the damping force that weakens vibration.
Particularly, make to hang by the elastic force that is formed on 40b of slit portion on the above-mentioned suspension lid 40 and compression spring 50 and cover 40 and further tighten up the chock effect of playing to the inside, can increase exponentially above-mentioned suspension cover 40 and leg axle 30 between force of sliding friction.
So, the cushioning effect of lift span 40a inner peripheral surface and the force of sliding friction between the leg axle 30, the rubbing surface 61 that is arranged on the caulking gum 60 on the above-mentioned suspension lid 40 and the force of sliding friction between the leg axle 30 and the above-mentioned compression spring 50 of the suspension lid 40 by constituting the leg assembly vibration of absorption system effectively makes system stability, so can prevent to possess mobile (walking) phenomenon of the roller washing machine that above-mentioned leg assembly is arranged, can mildly wash and dewater.
