Summary of the invention
In the utility model, in order to give one from the cushion effect of little arrival gradually changeable, reducing the generation of impulsive force, reducing the generation of abnormal sound, improve the service life of sewage disposer, the utility model provides a kind of sewage disposer with shock absorber.
For achieving the above object, a kind of sewage disposer with shock absorber, comprises mount pad and driving arm, and driving arm is articulated on mount pad; Driving arm is provided with elastic overturning mechanism; Also comprise hard-wired elastic component; Driving arm is provided with can with the buffering lug boss of elastic component effect, fold direction by driving arm, buffering lug boss is thickening gradually to the other end from one end.
Said structure, when driving arm is opened, once elastic component and the effect of buffering lug boss, the partial action that then elastic component is first thinner with buffering lug boss, then effect is divided with the thicker of buffer part lug boss, in this process, can there is elastic deformation in elastic component, meanwhile, elastic component also can change from small to big with the application force of buffering lug boss, the cushion effect that allows gradually increases, realize the progressive formation of cushion effect, like this, the impulsive force that driving arm produces is little, be not easy the phenomenon producing abnormal sound, the service life of sewage disposer can be improved simultaneously.
Further, cushion the speed that when position of lug boss on driving arm is opened according to driving arm, buffering lug boss contacts with elastic component to arrange.This design, driving arm is in opening procedure, when needs buffering lug boss contacts as early as possible with elastic component and plays buffer action, buffering lug boss can be arranged near elastic component, when needs buffering lug boss contacts more slowly with elastic component and plays buffer action, buffering lug boss slightly can be arranged away from elastic component, like this, the angle playing the driving arm of buffer action can control.
Further, described elastic component comprises elastic joint part and spring support, and elastic joint part is connected on mount pad, and spring support is provided with through hole, is upwards extended with shell fragment from the bottom of through hole, described shell fragment can with buffering lug boss effect.This structure is not only convenient installs elastic component, and owing to being provided with shell fragment separately, therefore, makes the performance of buffering good; In addition, because flexure strip is formed at through hole, therefore, taking of space can be reduced.
Further, mount pad is provided with and keeps out wall, mount pad and keep out between wall and be formed with slot, keep out to be formed between the lower surface of wall and mount pad and dodge room; The both sides that described elastic joint part comprises elastic joint part body and own elasticity connecting portion body inwardly or bent outward foldable type is flexible keeps out sheet; Elastic joint part inserted by main body is in slot, and elasticity is kept out sheet and is positioned at and dodges room, keeps out wall and withstands elasticity and keep out sheet.This structure, elastic joint part is installed by slot, and utilizes elasticity to keep out sheet and keep out wall and carry out spacing to elastic joint part, and like this, be not only easy for installation and removal elastic component, and the fixation of elastic component, reliable.
Further, described spring support comprises own elasticity connecting portion and bends the spring support body that the spring support connecting portion of extension and own elasticity seat connecting portion upwards extend laterally, and the intensity of this structural elasticity seat is high.
Further, the middle part of shell fragment or middle part is top has to projecting inward contact part, can allow buffering lug boss contact with contact part long-time failure-free, thus the reliability that raising cushions.
Further, described contact part is V-arrangement or arc.
Further, described driving arm comprises pivotally connected set and is located at the flip-arm in pivotally connected set; Described buffering lug boss is located on the outer circumference surface of pivotally connected set.
Further, mount pad is provided with pivot connecting seat, mount pad is provided with position-limited trough; Pivot connecting seat is provided with drive-connecting shaft; Drive-connecting shaft is arranged with damping due to rotation, and an end of the inner sleeve of damping due to rotation is connected with pivotally connected set detouchable, and outer the putting of damping due to rotation is provided with spacing preiection, and spacing preiection holding is in position-limited trough.In the structure shown here, first utilize damping due to rotation to carry out first-level buffer, recycling buffering lug boss and elastic component realize level 2 buffering, like this, make the better effects if cushioned.
Further, described elastic overturning mechanism is spring.Also comprise ladle body and bung, mount pad is fixed on ladle body, and bung is fixed on driving arm.
