Ink supply nozzle facilitating fixing of sealing rubber ring, ink box and maintenance box

Abstract

The invention relates to the technical field of printing, and discloses an ink supply nozzle facilitating fixing of a sealing rubber ring. The ink supply nozzle comprises a body, the first end of thebody is provided with a bulge, the body is provided with an inner hole, the sealing rubber ring is arranged in the inner hole of the body, after the sealing rubber ring is arranged, a hot welding headis used for welding the bulge, and the bulge bends and deforms towards the inner hole under certain temperature and pressure, so that an inverted buckle structure is formed, and the purpose of fixingthe sealing rubber ring is achieved. The fixing manner is simple in structure, the processing cost is lower, the production efficiency is improved, the use is convenient, and the fixing is reliable while it is ensured that the sealing rubber ring does not not remain in a printer or fall off. The invention further provides an ink box with the ink supply nozzle and a maintenance box, and when the ink box or the maintenance box is taken out of the printer, it can be guaranteed that the sealing rubber ring cannot remain in the printer or disengage from the inner hole of the ink supply nozzle.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an ink supply nozzle, an ink cartridge and a maintenance box for fixing a sealing rubber ring. Background technique [0002] The ink cartridge or the maintenance box is connected with the ink filling nozzle of the printer through the ink supply nozzle, and a sealing rubber ring is installed in the inner hole of the ink supply nozzle to prevent ink leakage. When taking out the ink cartridge or maintenance box from the printer, in order to prevent the sealing rubber ring from remaining in the printer or falling off from the inner hole of the ink supply nozzle, it is necessary to fix the sealing rubber ring in the inner hole of the ink supply nozzle. [0003] In the prior art, two methods are generally used to fix the sealing rubber ring on the ink supply nozzle: the first method is to fix by adding a plastic ring, but the fixing method of adding a plastic ring will increase the ma...

Problems solved by technology

[0003] In the prior art, two methods are generally used to fix the sealing rubber ring on the ink supply nozzle: the first method is to fix by adding a plastic ring, but the fixing method of adding a plastic ring will increase the manufacturing cost of the product, such as the plastic ring The mold opening cost, the staff cost of the process equipment due to the increase in the production process, and the increase in the production process will also lead to a decrease in production efficiency. In addition, it is also necessary to design a card that is connected with the plastic ring on the ink cartridge or maintenance box. Buckle structure, which further increases the manufacturing cost of the product

The second method is to weld a layer of film on the ink supply nozzle to fix the sealing rubber ring in the inner hole. This fixing method will also increase the manufacturing cost of the product, such as the material cost of the film and the cost of tooling and fixtures for welding the film, etc. And it will also lead to a reduction in production efficiency. In addition, when the ink cartridge or maintenance box is inserted into the printer, it needs to be pushed hard to make the ink filling nozzle of the printer break through the film and connect the ink supply nozzle. Risk of scratching or damaging the printer
