The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The structural representation that Fig. 1 is the utility model the first embodiment;
Fig. 2 is the structural representation that buffer spring does not bear spring base while loading;
Fig. 3 is the structural representation that buffer spring bears spring base while loading;
The structural representation that Fig. 4 is the utility model the second embodiment;
The structural representation that Fig. 5 is the third embodiment of the utility model.
The specific embodiment
Be illustrated in figure 1 the utility model the first embodiment.The pulsator washing machine derrick rig, comprise suspension rod 1, be sheathed on the spring base 2 of suspension rod, the gooseneck bracket 4 of being located at the sliding seat 3 of suspension rod lower end and being located at the suspension rod upper end, be provided with the axially extending bore 21 for installing suspension rod in spring base, be positioned with buffer spring 5 between sliding seat and spring base, spring base comprises damper portion 22 and the location division 23 that connects vertically setting, damper portion 22 is positioned at the below of location division 23, and axially extending bore runs through damper portion and location division from bottom to top successively.Spring base is to have the spring base that reversible shape-changing material is made, as rubber, the surface that location division is connected with damper portion is locating surface 231, locating surface be the diameter near damper portion little, away from the diameter of damper portion large tapering anchor ring, the upper end of buffer spring is enclosed within on damper portion and is butted on the part of locating surface near damper portion, and the lower end of buffer spring is positioned on sliding seat.
As shown in Figure 2, the end face of damper portion is provided with grooving 25, thereby grooving extends to vertically location division and damper portion is divided into to first 221 and second portion 222 from the end face of damper portion, the axis of axially extending bore is arranged in grooving, be that suspension rod passes between first and second portion, be equipped with the caulking groove 24 of the damping block of can packing in first and second portion, damping block 6 is housed in caulking groove, damping block 6 and caulking groove close-fitting.Caulking groove in first is located at the sidewall of first and is run through first and is communicated with grooving, caulking groove in second portion towards an end of first with grooving, be communicated with, an end sealing of first dorsad, the damping block of second portion is packed into through the caulking groove in first in the caulking groove of second portion, and then the damping block of first is packed in the caulking groove of first, the oral area that caulking groove is positioned at first's sidewall is provided with the positioning convex 241 of locating damping block, damping block is packed into after caulking groove, and positioning convex can be absorbed in damping block.Because the axis of axially extending bore is arranged in grooving, and caulking groove is communicated with grooving, caulking groove is communicated with axially extending bore simultaneously, that is to say that caulking groove is the position at corresponding axially extending bore place with the position that grooving is communicated with, and damping block just likely contacts with suspension rod and produces damping force like this.
As shown in Figure 3, when spring base and sliding seat compression buffer spring, buffer spring produces the active force of direction shown in arrow in Fig. 3 to spring base, and locating surface is subject to the extruding generation deformation of buffer spring, the inner ring of locating surface makes progress and inwardly deformation, and damper portion is connected with the inner ring of locating surface, so the deformation meeting of locating surface makes the first of damper portion and second portion also make progress and move inward, thereby make first and second portion mutually close, damping block is close to suspension rod generation damping force like this.And, when buffer spring is not loaded, spring base recovers automatically, form gap as shown in Figure 2 between damping block and suspension rod.
In above-described embodiment, caulking groove in second portion also can adopt the structure of the caulking groove of similar first, be about to caulking groove in second portion and be located at the sidewall of second portion and run through second portion and be communicated with grooving, the oral area that then at caulking groove, is positioned at the second portion sidewall arranges positioning convex.In addition, also can be only in first or only in second portion, be provided with the caulking groove of the damping block of can packing into, although that the damping force produced does not arrange the damping force of structure generation of two damping blocks is large, can realize damping effect too.
Also have, except the sidewall in damper portion arranges caulking groove, also can caulking groove be set at the end face of damper portion, as shown in Figure 4, caulking groove 24 to location division 23 place directions extend, now caulking groove and grooving 25 are combined into a groove, damping block 6 blocks at two end faces radially by caulking groove.Then the oral area that is positioned at the damper portion end face at caulking groove arranges the positioning convex 241 of location damping block.And the caulking groove of the caulking groove of first and second portion needn't unify to adopt identical version, for example the caulking groove of first is located at the sidewall of first, and the caulking groove of second portion is located at the end face of second portion and is extended to place, location division direction.
In above-described embodiment, make the structure of spring base deformation, also can be as shown in Figure 5, inner ring at buffer spring 5 arranges a pushing block with inclined-plane 51, the inclined-plane 511 of pushing block is towards damper portion 22, and the incline direction on this inclined-plane should be from top to bottom constantly near the incline direction of boom axis, after buffer spring constantly compresses, pushing block is followed buffer spring and is moved upward, the ramp effect of pushing block is on damper portion, by the axial force of buffer spring change into radial load make the first of damper portion and second portion mutually close, thereby make damping block be close to suspension rod and produce damping force.And buffer spring has the character of resetting, when not loaded, pushing block automatically just follow that buffer spring resets and with damping portion from, and damper portion is also recovered automatically.Perhaps the inner ring at buffer spring arranges a ring of the promotion with the tapering anchor ring, and the diameter of tapering anchor ring upper end is larger than the diameter of lower end, and principle arranges the identical of pushing block with above-mentioned, repeats no more.
Except above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
