Embodiment
As shown in Figure 1, the right-hand member of connecting rod 7 and seat board 8 are hinged, are with rubber body 3 on connecting rod 7, and the connecting plate 4 that is installed on the connecting rod 7 is arranged at the middle part of described rubber body 3, and the end of described connecting plate 4 passes described rubber body 3.Between the left end of described rubber body 3 and connecting rod 7, left pressing plate 2 is set, between the right-hand member of rubber body 3 and connecting rod 7, right pressing plate 5 is set.Described left pressing plate 2 all is provided with cone boss with the middle part of right pressing plate 5, and described cone boss is between described rubber body 3 and described connecting rod 7; Described left pressing plate 2 all is provided with tray-shaped base with the bottom of right pressing plate 5, and the end face of described tray-shaped base is close on the end face of described rubber body 3.
The hinged mounting plate 11 in the outer end of connecting plate 4.Position corresponding to connecting plate 4 on connecting rod 7 is provided with connecting sleeve 12, and described connecting sleeve 12 is fixedlyed connected with described connecting plate 4.The nut 1 that is spirally connected in the left part of connecting rod 7, the right side corresponding to right pressing plate 5 on connecting rod 7 is provided with step, and the setting sleeve 6 that is enclosed within connecting rod 7 outsides is set between described step and described right pressing plate 5.Base plate is arranged described seat board 8 and perpendicular to the left sideboard and the right sideboard of base plate both sides, the right-hand member of described connecting rod 7 utilizes bearing pin 9 to be articulated on the described side plate, between described connecting rod 7 and described bearing pin 9 axle sleeve 10 is arranged.One end of described bearing pin 10 has positioning seat, and the other end has locating slot, and location piece 17 is set on described right sideboard, and the edge of described location piece 17 embeds in the described locating slot.Described seat board 8 is installed on down on the plastid 15, the hinged mounting plate 11 in the outer end of connecting plate 4, and described mounting plate 11 is installed on the plastid 14, and the two ends of 15 of plastid 14 and described plastids down are provided with spring 13 on described.During installation, in uneasy motorized two sides of double-mass vibrating flask shaker, neutral position or end positions in this side are installed one group or two groups of devices described in the utility model simultaneously, and seat board 8 is fixed on down on the plastid 15; Mounting plate 11 on the connecting plate 4 is fixed on the plastid 14, forms the swung connection of upper and lower plastid 14,15.Last plastid 14 also has exciting vibration spring 13 to be connected with 15 of plastids down, and exciting vibration spring 13 is made resiliently deformable when vibration, and its Oscillation Amplitude is subjected to the effect of elastic link 7 and is limited, retrains the super oscillation amplitude change of plastid.
