Abstract:
1. An anti-vibration mechanism for a dental impression material mixer, for enhancing the stability of a motor and every mechanism mounted on a top of the motor during operation, such anti-vibration mechanism comprising: a plurality of vertically extending supporting poles; a plurality of first elastic springs, each first elastic spring connecting a corresponding position at a top end of the adjacent supporting pole and a top of the motor; a plurality of second elastic springs, each second elastic spring connecting a corresponding position at a bottom end of the adjacent supporting pole and a bottom of the motor; a horizontally extending base plate, which is fixedly equipped at the bottom end of each supporting pole; a horizontally extending restricting board separate from said supporting poles which consists of a central opening, the central opening being smaller than an area defined by said supporting poles, each of the supporting poles passing through edge corners of the restricting board, the restricting board being fixedly located at the middle portions of the supporting poles, the position of the motor being restricted at the central opening of the restricting board, by its linkage to the first elastic spring and the second elastic spring and the motor hanging above the base plate; and each supporting pole further including a primary body and a secondary portion, the circumference of the secondary portion is less than the circumference of the primary body, and there are threads on the secondary portion located adjacent to the primary body, a nut is fastened on the threads, and the nut can fasten and fix the restricting board on the primary body of the supporting pole.
