Description

Technical Field

[0001] The utility model relates to the technical field of printing devices, and particularly relates to an open-cover structure with a large opening angle. Background Technique

[0002] A printing device is one of the output devices of a computer, used to print the processing results of the computer on relevant media. There are many types of printers. According to whether the printing element has a striking action on the paper, it is divided into impact printers and non-impact printers. According to the printing character structure, it is divided into full-shape character printers and dot-matrix character printers. The basic working principle of an inkjet printer is to first generate small ink droplets, and then use the inkjet head to guide the fine ink droplets to the set positions. The smaller the ink droplets, the clearer the printed picture. The serial dot-matrix character non-impact printer mainly has two types: inkjet printers and thermal printers. Ordinary paper is used for printing, and this typewriter can also be directly used to print characters on certain products. There is no mechanical wear during the formation of characters and graphics, the printing energy consumption is small, and the heat generated by the pulse current flowing through the dot resistance of the print head is transmitted to the thermal paper, causing it to change color by heating, thereby printing characters and images.

[0003] The consumables inside the printing device need to be taken out and replaced regularly, especially the ink cartridges inside the inkjet printing device. After the printing device has been used for a period of time, the ink cartridges inside the inkjet printing device need to be replaced with new ones to facilitate subsequent printing.

[0004] After retrieval, for the same type of printers on the market, the internal flip cover is hinged to the base and nested inside the base. When the internal flip cover is opened, the internal flip cover is restricted by the edge of the base and can only be opened at a very small angle. One needs to reach into this narrow space to take out the old consumables and then put in the new ones, which is inconvenient to operate.

[0005] There is an urgent need for an open-cover structure with a large opening angle to solve the technical defects mentioned in the above technology. Content of the Utility Model

[0006] The purpose of the utility model is to provide an open-cover structure with a large opening angle to solve the problem that the internal flip cover cannot be fully opened mentioned in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: An open-cover structure with a large opening angle, including a printer base. One side of the top of the printer base is provided with an internal printer flip cover. The top of the internal printer flip cover is provided with an external printer flip cover, and the external printer flip cover is movably hinged to the printer base. One side of the internal printer flip cover away from the opening is provided with a flip cover connecting slide column. One side of both ends inside the printer base is provided with a flip cover connecting slide groove. A limiting groove is provided on one side of the flip cover connecting slide groove. Both ends of the internal printer flip cover are movably hinged with flip cover connecting rods.

[0008] Preferably, the flip link is disposed on a side close to the flip connection chute, and one end of the flip link is movably connected to the printer base.

[0009] Preferably, one end of the flip connection sliding column can be embedded inside the flip connection chute and is slidably connected.

[0010] Preferably, the size of the external flip of the printer is larger than the size of the internal flip of the printer.

[0011] Preferably, when the internal flip of the printer is closed, the flip connection sliding column slides towards one end away from the middle of the printer base under the action of the flip link.

[0012] Preferably, the limiting groove is disposed on one side of the bottom end of the flip connection chute, and the flip connection sliding column can be embedded inside the limiting groove.
