Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the utility model is not intended to limit the scope of the utility model.

The portable ribbon supply mechanism includes a printhead mount 100 and an ink ribbon cartridge 200. The ink ribbon cartridge 200 stores ink ribbon therein, which passes through the printhead mount 100.

As shown in fig. 1, which is a schematic structural diagram of the printhead mounting bracket, the printhead mounting bracket 100 includes a base 10, an inclined bracket 20 obliquely disposed on the base 10, a transverse bracket 30 connected to an end of the inclined bracket 20 away from the base 10, and two ribbon guide brackets 40 connected to an end of the transverse bracket 30 away from the inclined bracket 20 at an angle.

The middle part of the oblique bracket 20 is provided with a rectangular mounting opening 21.

A rectangular first hollow notch 31 is formed in the middle of the transverse bracket 30, so that two first support legs 41 are formed on one side of the transverse bracket 30 away from the inclined bracket 20.

The two ribbon guide brackets 40 are respectively connected at an angle to the two first legs 41 of the transverse bracket 30. The angle between the ribbon guide bracket 40 and the first leg 41 is 15-45 degrees, one side of the ribbon guide bracket 40 close to the first hollow gap 31 is far away from the base 10, and one side of the ribbon guide bracket 40 far away from the first hollow gap 31 is close to the base 10. The two ribbon guide supports 40 are symmetrically disposed along the center line of the first hollow 31.

The side of the two ribbon guide supports 40 facing the base 10 near the first opening 31 is provided with a mounting groove 43 for mounting a print head.

Two ends of one side of the ribbon guide bracket 40 away from the first hollow gap 31 are respectively provided with two second legs 42 which are obliquely and convexly arranged outwards, and the tail ends of the two second legs 42 are oppositely extended with guide posts 44.

A ribbon channel 45 is provided in the middle of the guide post 44, and a ribbon port 46 is provided between the guide post 44 and the ribbon guide bracket 40.

Referring to fig. 2, in use, the portable ribbon supply mechanism passes ribbon through the ribbon ports 46 on both sides of the ribbon guide support 40. The ribbon is partially located on the side of the ribbon guide support 40 remote from the base 10.

A print head moving drive unit is connected to the base 10, and the print head passes through the two ribbon guide brackets 40 to act on the ribbon, thereby printing characters, numbers or patterns on the paper.

Referring to fig. 3, the ribbon cartridge 200 is provided with a rectangular mounting hole 51, and a mounting head 50 is disposed in the mounting hole 51. The mounting head 50 comprises a transverse strut 52 connected with one inner side wall of the mounting hole 51 and a vertical strut 53 vertically connected with the transverse strut 52, wherein two sides of the top of the vertical strut 53 are respectively provided with a buckle head 54 in a protruding manner, and the middle of the top of the vertical strut 53 is provided with a second hollow gap 55.

When the portable ink ribbon supply mechanism is not in use, the print head 100 is locked to the mounting head 50 through the mounting opening 21, and is convenient to carry.

The ribbon path 45 is used to take out or load the ribbon.

It is contemplated that the ribbon cartridge 200 may also be provided with a hook that can be hung elsewhere for convenient storage when the cartridge is removed from the printer.

In contrast to the prior art, the present invention provides a portable ribbon supply mechanism that positions the printhead mount 100 when not in use by mating the mounting port 21 with the mounting head 50 on the ribbon cartridge. When in use, the utility model can be directly taken down and installed, which is convenient and fast and not easy to lose.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
