Product design sample manuscript copying device and copying method thereof

Abstract

The invention relates to the technical field of product design, and particularly relates to a product design sample manuscript copying device which comprises a shell. A lifting shell is arranged on the outer wall of the top of the shell, a lamp box is arranged on the top of the lifting shell, a cover plate is connected to the outer wall of the top of the lamp box through hinges, two fixing plates are welded to the inner wall of the top of the lifting shell, a connecting shaft is connected to the interiors of the two fixing plates through bearings, two connecting plates are welded to the outer wall of the bottom of the lamp box and welded to the two ends of the connecting shaft respectively, ratchet wheels are welded to the outer walls of the connecting shaft, a shifting shaft is connected between the inner walls of the two sides of the lifting shell through bearings, the outer parts of the shifting shaft are connected with non-return plates through bolts, and the non-return plates are matched with the ratchet wheels. According to the product design sample manuscript copying device provided by the invention, the non-return plates are matched with the ratchet wheels, so that the non-return plates enable the ratchet wheels to only rotate in one direction through the elastic force of torsional springs, and then the lamp box is fixed at an inclination angle, so that the effect that a workbench can be inclined at multiple angles during copying is achieved.

Description

technical field [0001] The invention relates to the technical field of product design devices, in particular to a product design sample copying device and a copying method thereof. Background technique [0002] At present, with the continuous expansion of the international mechanical product market, the design of mechanical products has developed rapidly. In the design of mechanical products, it is necessary to design multiple prototypes first, and then integrate the advantages of multiple prototypes to make it a more perfect product. Therefore, it is necessary to copy each complex sample drawing to extract the advantages and structures of each sample, so as to facilitate the design of products with comprehensive advantages. [0003] China Patent No. 201510693349.2 relates to a mechanical product design sample copying system, including a water storage system, a drawing board is installed on the slope on the right side of the water storage system, and a drying treatment rod i...
