Plate Carrying Apparatus

Abstract

A plate-carrying apparatus comprises a base, an adjusting rack assembly, a telescopic supporting rack and a bearing seat. The base is connected to the adjusting rack assembly and the telescopic supporting rack, respectively. The adjusting rack assembly is pivotally connected to the bearing seat. A height adjusting mechanism formed by the base and the adjusting rack presses against the bearing seat to fix it, such that the carrying height of the bearing seat can be easily controlled. In addition, the bearing seat is pivotally connected to the adjusting rack assembly, so the bearing seat can be collected by rotating the bearing seat relative to the adjusting rack assembly, so as to reduce the storage space.

1 . A plate-carrying apparatus, comprising:
 a base;   an adjusting rack assembly having a plurality of racks, a rod and a driving assembly, the racks being disposed side by side on the base, each rack having two rods connected by a pivotal portion, one of the rods of each rack being pivotally disposed at the base, the other rod of each rack being pivotally connected to the rod of the adjusting rack assembly, the driving assembly being connected to the base and the rod of the adjusting rack assembly, respectively to move the rod of the adjusting rack assembly relative to the base;   a telescopic supporting rack disposed on the base; and   a bearing seat pivotally connected to the pivotal portion of the respective racks of the adjusting rack assembly, the telescopic supporting rack presses against the bearing seat to fix it.   
   
   
       2 . The plate-carrying apparatus as claimed in  claim 1 , wherein one lateral side of the base is disposed with a plurality of rollers. 
   
   
       3 . The plate-carrying apparatus as claimed in  claim 1 , wherein the rods of one rack of the adjusting rack assembly are pivotally disposed with a buffer member, respectively, and the buffer members are pivotally connected to the bearing seat. 
   
   
       4 . The plate-carrying apparatus as claimed in  claim 3 , wherein the buffer members of the adjusting rack assembly are shock absorbers or nitrogen cylinders. 
   
   
       5 . The plate-carrying apparatus as claimed in  claim 1 , wherein the driving assembly of the adjusting rack assembly includes two shaft seats, a displacement seat, a screw and a handle, the shaft seats are mounted on the base, respectively, the displacement seat is disposed at the rod of the adjusting rack assembly, the screw is passed through the shaft seats and is threaded with the displacement seat, the handle is disposed at one end of the screw. 
   
   
       6 . The plate-carrying apparatus as claimed in  claim 1 , wherein the bearing seat includes a connecting rod and a carrying member, the connecting rod is hinged to the carrying member by a plurality of hinge members and is pivotally connected to the pivotal portions of the racks of the adjusting rack assembly, and the telescopic supporting rack presses against the carrying member to fix it. 
   
   
       7 . The plate-carrying apparatus as claimed in  claim 1 , wherein the rods of one rack of the adjusting rack assembly are pivotally disposed with a buffer member, respectively, the bearing seat includes a connecting rod and a carrying member, the connecting rod is hinged to the carrying member by a plurality of hinge members, the telescopic supporting rack presses against the carrying member to fix it, and the carrying member is pivotally connected to the buffer members of the adjusting rack assembly. 
   
   
       8 . The plate-carrying apparatus as claimed in  claim 1 , wherein a plurality of balls is disposed on the bearing seat. 
   
   
       9 . The plate-carrying apparatus as claimed in  claim 6 , wherein a plurality of balls is disposed on the carrying member of the bearing seat. 
   
   
       10 . The plate-carrying apparatus as claimed in  claim 7 , wherein a plurality of balls is disposed on the carrying member of the bearing seat.
