Detailed description of the invention
As shown in Figure 3, the shock-absorbing suspension rod 1 of the present invention is made up of upper ball base 6, spring 9 and spring base 10, fixed block 8 is installed between upper ball base and spring, fixed block typically uses elastic plastics to make, fixed block and upper ball base opposite side are provided with multiple symmetrical fixing post 12 protruded, the positioning table 13 protruded outside the oriented axle center, top of fixing post.As shown in Figure 1, the arc-shaped seat that flap seat 2 is an opening upwards on casing of washing machine 4, it is arranged on top inside casing of washing machine, have in the side of flap seat and accommodate the fracture that suspension rod passes, upper ball base is a semicircle identical with flap seat shape, and one end of suspension rod 7 can not be deviate from after being passed by the through hole in the middle of upper ball base again, by suspension rod through the fracture on flap seat, blocking the fracture of flap seat in upper ball base is inserted flap seat again, the upper end of such shock-absorbing suspension rod just completes to install.The side of the outer barrel of washing machine 7 relative with flap seat is provided with cushion socket 3, a fracture 15 more than suspension rod diameter is had equally on cushion socket, there is the through hole passed for suspension rod in the axle center of cushion socket, surrounding at through hole has on for fixed block fixes the gap 16 that post 12 passes through, suspension rod 7 is after the fracture 15 of cushion socket enters the through hole in cushion socket axle center, fixed block inserts in cushion socket from the lower section of cushion socket, fixing post on fixed block utilizes positioning table 13 to be fixed on cushion socket after cushion socket, so fracture on cushion socket is just shut by fixed block, complete the installation of shock-absorbing suspension rod lower end simultaneously.
As it is shown on figure 3, fixed block 8 contacts with spring 9 is provided with groove an equal amount of with spring diameter in one side, spring contact end is contained in groove, is so possible to prevent spring offset to affect damping effect.
This programme is not limited on cushion socket install fixed block, and same upper ball base can also use the structure of fixed block to be fixed in flap seat by suspension rod, and the upper and lower end of such shock-absorbing suspension rod is the most all fixed on bearing, entirely prevented unhook phenomenon.
Fixed block can also be combined with shock-absorbing suspension rod of the prior art as independent parts, i.e. the upper end of shock-absorbing suspension rod installs fixed block between upper ball base and flap seat, is formed and can contact with the arc of arbitrarily angled activity between upper ball base with fixed block.Same in the lower end of shock-absorbing suspension rod, the arc as fixed block is formed with the contact surface of lower ball base is fitted.Above-mentioned mounting means is under the damping effect not affecting existing shock-absorbing suspension rod, it is to avoid unhook phenomenon.
nullAs shown in Figure 3，The axial channel of fixed block 8 can be configured with the passage 14 of certain tube wall，The length of passage 14 is typically provided to 1～2 times of fixed block itself height，The interior diameter of passage is slightly larger than the diameter of suspension rod，Passage forms the effect of a relative clamping after fixed block is fixing to suspension rod，This effect is mainly reflected in suspension rod when there is axial motion，And do not affect the activity of suspension rod above-below direction，Passage limits suspension rod can do elastically-deformable length，Passage can limit the range of activity of internally positioned boom sections simultaneously，When the centrifugal force that outer barrel is subject within the specific limits time，Passage does not produce impact to suspension rod，When the centrifugal force that outer barrel is subject to exceedes certain limit，When i.e. producing the eccentric force that can touch bucket，Passage can limit suspension rod on axis direction range of activity，Suddenly the eccentric force increased is produced a counteracting force，Thus spread and reduce the size of this centrifugal force，Under on symmetry direction, multiple shock-absorbing suspension rods of distribution act on simultaneously，This centrifugal force is just made to include in completely in shock-absorbing suspension rod controlled range，Thus avoid washing machine and touch the generation of barrel phenomenon.
The fixed form of fixed block 8 can also use other structure, as long as being closed by fracture on flap seat or cushion socket and not hindering suspension rod freely movable fixed structure can.As shown in Figure 5, fixed block is that side has the little hollow taper cylinder in the big one end of fracture 15 and one end, the appropriate location of the lateral wall of fixed block arranges the fixed station 17 engaged with flap seat 2 or cushion socket 3, fixed station is generally located in the middle part of cone is partial to one end that diameter is big, after suspension rod is cut in flap seat or cushion socket and fixed block, fixed block is inserted in flap seat or cushion socket after a segment distance, snap-in structure outside fixed block is fixed with flap seat or cushion socket, and now fixed block is shrunk to a cylinder closed under the constraint of flap seat or cushion socket.
Fixed block can also use between flap seat or cushion socket the structure that can enter stationary state after axial-rotation certain angle.The flap seat of washing machine and cushion socket be all adopt made of plastic, fracture diameter above can be less than the diameter 0.1～0.4mm of suspension rod, suspension rod needs to overcome certain elastic deformation when entering fracture, so in the case of not bigger external force, the suspension rod entering flap seat and spring base also would not be deviate from.
