PCR tube pressing mechanism

Abstract

The utility model discloses a PCR pipe gland mechanism, apply in PCR pipe technical field, including the bottom plate, the top of bottom plate is provided with the top plate, the top of bottom plate and the bottom part of top plate are respectively bolted with mobile motor and gland motor, the output of mobile motor is bolted with mobile screw rod, the side away from mobile motor of bottom plate top is bolted with sliding rail, the top of sliding rail is slidably connected with fixed seat. The automatic alignment of the eight pipe cover and eight pipe body of placing can be carried out through the conical chamfered groove of the top of fixed seat, the conical slope is used to guide, the fixed position remains unchanged, and the center point is fixed. When the gland plate and pipe cover support plate slide up and down, the support column is used for limiting, and the pipe cover support only makes up and down movement, so that the displacement generated by horizontal movement can be avoided. At the same time, the supporting spring piece also does not take up the eight pipe when moving on the gland plate, so as to guarantee the accuracy of the gland, improve the gland efficiency.
