Description

Convenient replacement structure of printer cartridge Technical Field The application relates to the technical field of printers, in particular to a convenient replacing structure of a printer carbon powder box. Background The main component of the carbon powder used by the printer is black plastic powder, a carbon powder box is arranged in the printer for containing the toner, when the laser printer is printing, the toner is required to be continuously consumed, so that the toner cartridge is required to be disassembled and replaced after the toner is used up. The existing toner cartridge fixing mode generally adopts a traditional screw fastening structure, and the design is inconvenient to assemble and disassemble and needs to take a long time although the installation stability can be ensured, so that the structure for conveniently replacing the toner cartridge of the printer is improved. Disclosure of utility model Aiming at the defects of the prior art, the application provides a convenient replacement structure of a printer toner cartridge, overcomes the defects of the prior art, and aims to solve the problems that the prior toner cartridge fixing mode commonly adopts a traditional screw fastening structure, and the design can ensure the installation stability, but is inconvenient in disassembly and assembly and takes a long time. The printer toner cartridge convenient replacement structure comprises a printer main body, wherein a bin is arranged on the front side of the printer main body, a bin door is rotatably connected to the bottom of the bin, an installation box is slidably inserted into the bin, a toner cartridge is placed in the installation box, a plurality of positioning blocks are fixedly connected to the bottom of the installation box, a plurality of positioning grooves matched with the positioning blocks are formed in the bottom of the toner cartridge, fixing grooves are symmetrically formed in the two sides of the upper surface of the installation box, fixing rods are symmetrically connected with the outer walls of the two sides of the toner cartridge, the fixing rods are slidably inserted into the fixing grooves, a telescopic groove is formed in the installation box, a lock tongue is slidably inserted into the telescopic groove, the lock tongue is fixedly connected with the telescopic groove through a spring, and the lock tongue is slidably inserted into the fixing grooves under the action of the elasticity of the spring to limit the fixing rods.
