The specific embodiment

Fig. 2 is a dehydration barrel schematic diagram of the present utility model.Comprise: staving 2, the flange shaft 6 of being located at the gimbal 1 of staving 2 oral areas and being located at staving bottom are formed.Be evenly equipped with a plurality of sieve apertures 5 on the bucket wall of this staving 2; Upper end-face edge at staving 2 is provided with a plurality of snappings hole 9 (please consulting Fig. 3 simultaneously).This gimbal lower end is concave inward structure and has a plurality of toe buttons 8 that dehydration staving 2 is by fastening with the snapping of toe button 8 by snapping hole 9 in the inner groovy that inserts the gimbal lower end on the staving with the fastening of gimbal 1, thereby constitutes whole dehydration barrel 10.Its staving 2 is fixed in the connecting axle 12 that links to each other with dehydration electric motor 11 by the flange shaft 6 that injection moulding is inlaid in its lower end, thereby drives the function that dehydration barrel 10 rotations reach dehydration by drive of motor.

Fig. 3 is the local amplification profile of the utility model dehydration barrel gimbal and staving fastening position A.As seen from the figure, this gimbal 1 is made of interior ring 13, outer shroud 14 and collar 15, and its cross section is the П shape of lower end indent.On the outer wall of the interior ring 13 of this gimbal, corresponding to the position in each snapping hole 9 of staving 2 upper end-face edges, the upright elasticity toe button 8 that is provided with.This elasticity toe button 8 is to stand to establish an elastic cantilever 81 on the outer wall of interior ring 13, is provided with toe button 82 in the end of elastic cantilever 81.The upper surface of this toe button 82 is the plane, and lower surface is the inclined-plane.When staving upper end is inserted in the inner groovy of gimbal lower end, the lower inclined plane of top toe button 82 is touched in the staving upper end, make elastic cantilever 81 elastic bendings of toe button 8, when toe button 8 arrives at the snapping hole 9 of staving 2 upper end-face edges, toe button 8 enters snapping hole 9 under resilient force, by the last plane of toe button 8, the upper limb in contact snapping hole 9 and snapping is fastening.

In the embodiment shown in fig. 4, the inner face of the collar 15 ' of this gimbal 1 ', corresponding to the position in each snapping hole 9 of staving upper end-face edge, the upright downwards elasticity toe button 8 ' that is provided with.This elasticity toe button 8 ' faces down to stand in collar 15 ' and establishes an elastic cantilever 81 ', is provided with toe button 82 ' in the end of elastic cantilever 81 '.The upper surface of this toe button 82 ' is the plane, and lower surface is the inclined-plane.When staving upper end is inserted in the inner groovy of gimbal lower end, the lower inclined plane of top toe button 82 ' is touched in the staving upper end, make the elastic cantilever 81 ' elastic bending of toe button 8 ', when toe button 8 ' arrives at the snapping hole 9 of staving 2 upper end-face edges, toe button 8 ' enters snapping hole 9 under resilient force, by the last plane of toe button 8 ', the upper limb in contact snapping hole 9 and snapping is fastening.

As shown in the figure, the outer shroud 14 of this gimbal 1, the position corresponding to each snapping hole 9 of staving upper end-face edge has slotted eye 7 from bottom to top, is used to observe the toe button 8 of judging gimbal and whether aims at and enter snapping hole 9.

Outer shroud 14 inboards of this gimbal 1 also are provided with a step surface 16, and this gimbal 1 is coated at the periphery of staving 2 upper port with its outer shroud 14, and this step surface 16 is resisted against staving 2 upper port and locatees.Above-mentioned locate mode, can also be, lower edge in the snapping hole 9 of dehydration barrel staving 2 upper ends is provided with the reinforcing ring 4 of protrusion, and this gimbal 1 is coated at the periphery of staving 2 upper port with its outer shroud 14, and the port of the outer shroud 14 of gimbal 1 is resisted against the reinforcing ring 4 of this protrusion and locatees.And the outer circumference surface of the outer circumference surface of this reinforcing ring 4 and gimbal 1 is on same periphery.Thereby make dehydration staving 2 more natural with being connected of gimbal 1, whole dehydration barrel has more associative perception.

The snapping mode of dehydration barrel of the present utility model be toe button 8 from the inboard in snapping hole 9 snapping outward, thus snapping intensity guaranteed.

Of the present utility model by structural change, reduced the assembling parts and the assembling link of existing dehydration barrel fit on, thereby reduced manually, economical with materials reduces cost, and improves labor productivity.

The above only is the utility model specific embodiment; everyly be familiar with this skill personage and make various modifications or change very easily in view of the above; therefore, all equivalence replacements that the utility model claim spirit is done that do not break away from all should be included in this patent protection domain.
