Ribbon cartridge locking and ejecting device

Abstract

The invention discloses a ribbon cartridge locking and ejecting device. The ribbon cartridge locking and ejecting device comprises outer supporting side rods and a ribbon shell, wherein limiting innerrails are fixedly connected to the interiors of the outer supporting side rods respectively; adjusting transmission threaded rods are rotationally connected to the vertical positions of the interiorsof the limiting inner rails respectively; the outer surface of each adjusting transmission threaded rod is provided with and in threaded connection with a transmission internal thread sliding block in a sleeving mode; the side, close to the ribbon shell, of each transmission internal thread sliding block is fixedly connected with a mounting side clamping frame respectively; an anti-skid gasket isarranged at the end, located on the inner side of a mounting inner groove, of a fastening bolt; a locking limiting mechanism is fixedly connected to the position, close to the middle, of the outer side of a movable limiting connecting rod; and a safe ejecting mechanism is fixedly connected to the middle of the top end of the exterior of each outer supporting side rod. The invention relates to thetechnical field of ribbon cartridges. According to the ribbon cartridge locking and ejecting device, the aims that a locking mechanism is installed firstly, then the ribbon cartridge is installed, the installation precision of the ribbon cartridge is improved, and meanwhile the phenomenon that the ribbon cartridge is disengaged due to long-time work is avoided are achieved.

Description

technical field [0001] The invention relates to the technical field of ribbon cassettes, in particular to a locking and ejecting device for a ribbon cassette. Background technique [0002] Ribbon is a printing consumable that we are more familiar with. From the earliest mechanical impact type English printers to the later computer dot matrix printers, ribbons are used. The composition of the ribbon is very simple, that is, the ribbon base woven from nylon silk is soaked in ink and dyed. The working principle of the ribbon is to use the dot matrix striker in the head of the dot matrix printer or the letter striker in the English typewriter to hit the printing ribbon to produce a printing effect on the printing paper. [0003] The ribbon box is the ribbon rack, which is a special device for dot matrix printers to hold ribbons. Ribbon box = ribbon frame, ribbon = ribbon core. In other words, the ribbon is mounted on the ribbon cassette, which is secured to the printer. To ...
