Description

Wear-resistant guide rod for printer Technical Field The utility model relates to the technical field of printers, in particular to a wear-resistant guide rod for a printer. Background During operation of the printer, the guide bar plays a key role in supporting and guiding the movement of the print head slider. The traditional printer guide rod has the defects that firstly, the wear-resistant layer of the printer guide rod is generally of an integrated structure with the guide rod, when the wear-resistant layer on the surface of the printer guide rod cannot be independently replaced after being worn for a long time, the whole guide rod can only be replaced, so that the maintenance cost is increased, the resource waste is also caused, secondly, the distance between the traditional guide rods is fixed, the adjustment cannot be carried out according to the different sizes of the printing head slide blocks, the printer is difficult to adapt to the printing head slide blocks with various specifications, and the application range and the use flexibility of the printer are limited. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provide a novel wear-resistant guide rod for a printer, wherein wear-resistant plates of the novel wear-resistant guide rod are replaceable, the distance between an upper guide rod and a lower guide rod is quickly adjustable, and the middle printing head sliding block is quickly assembled and disassembled and the printing head sliding block with different sizes is adapted. In order to solve the technical problems, the utility model adopts the following technical scheme: The wear-resistant guide rod for the printer comprises an upper guide rod and a lower guide rod with V-shaped cross sections, wherein the tip sides of the upper guide rod and the lower guide rod are oppositely arranged, the distance between the tip sides of the upper guide rod and the lower guide rod is adjustable, and the V-shaped protruding surfaces of the upper guide rod and the lower guide rod are provided with replaceable wear-resistant sheets in a fitting manner; The left end and the right end of the upper guide rod and the lower guide rod are connected with supports, and the supports are connected with toothed plates and meshed with fixed-position toothed columns for transmission; A pressing block is arranged between the support and the wear-resistant piece. Further, the outer sides of the upper guide rod and the lower guide rod are provided with convex clamping edges, the inner side of the wear-resisting piece is provided with concave clamping grooves, and the clamping edges are matched with the clamping grooves in shape and position.
