DETAILED DESCRIPTION

[0020] The technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. In addition, the forms of the various structures described in the following embodiments are merely examples. A ribbon cassette for a label printing device according to the present utility model is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0021] Embodiment 1:

[0022] As Figures 1-5 shown, a ribbon cassette for a label printing device includes a ribbon cassette body 1. A roller 15 is installed inside the ribbon cassette body 1, and a label tape 16 is wound around the outer wall of the roller 15. A lid 2 is movably sleeved on the front surface inside the ribbon cassette body 1. Guide grooves 3 are opened at the four corners of the front surface of the lid 2, and limiting channels 4 are opened at the four corners inside the lid 2. The inside of the guide grooves 3 communicates with the inside of the limiting channels 4. A positioning plug 6 is provided inside the limiting channels 4. Positioning slots 7 are opened at the four corners of the inner wall of the ribbon cassette body 1. One end of the positioning plug 6 is inserted into the inside of the positioning slot 7. A pressing plate 8 is fixedly sleeved on the outer wall of the positioning plug 6. One side of the pressing plate 8 is fixedly connected to a spring 9. The spring 9 is movably sleeved on the outer wall of the positioning plug 6. One end of the spring 9 is fixedly connected to a positioning plate 10. The inside of the positioning plate 10 is movably sleeved on the outer wall of the positioning plug 6. The outer wall of the positioning plate 10 is fixedly connected to the inner wall of the limiting channel 4. Pushing pieces 31 are lapped at the four corners of the front surface of the lid 2. The middle part of the back surface of the pushing piece 31 is fixedly connected to a slider 5. The outer wall of the slider 5 is slidably connected inside the guide groove 3. The back surface of the slider 5 is fixedly connected to one end of the front surface of the positioning plug 6. The other end of the positioning plug 6 is fixedly connected to an iron sheet 11. One end of the inner wall of the limiting channel 4 is fixedly connected to a magnetic sheet 12.

[0023] In this embodiment, through the arrangement of the spring 9, it is convenient to elastically insert one end of the positioning plug 6 into the inside of the positioning slot 7. Through the arrangement of the pushing piece 31, it is convenient for the staff to move the slider 5. At the same time, the guide groove 3 is used to guide the slider 5, and the slider 5 drives the positioning plug 6 to move, so that one end of the positioning plug 6 is removed from the inside of the positioning slot 7. At the same time, the positioning plug 6 drives the pressing plate 8 to compress one end of the spring 9. The other end of the positioning plug 6 drives the iron sheet 11 to move to one side of the magnetic sheet 12 at the same time, and makes the iron sheet 11 and the magnetic sheet 12 magnetically adsorbed together, so as to position the positioning plug 6. (In this application, the adsorption force when the iron sheet 11 and the magnetic sheet 12 are magnetically adsorbed together is greater than the elasticity of the spring 9). At this time, the staff can take out the lid 2 from the inside of the ribbon cassette body 1, and then the ribbon cassette body 1 and the lid 2 can be disassembled.

[0024] Embodiment 2:

[0025] like Figures 1-5 As shown, a plurality of limit tubes 13 are fixedly connected to the interior of the ribbon box body 1, and a plurality of limit rods 14 adapted to the interior of the limit tubes 13 are fixedly connected to the back of the box cover 2. The front end of the limit tube 13 overlaps the back of the box cover 2, and the outer wall of the limit rod 14 is inserted into the interior of the limit tube 13.

[0026] In this embodiment, the limiting rod 14 is inserted into the limiting tube 13 , and the front end of the limiting tube 13 overlaps the back of the box cover 2 , so as to facilitate the limiting of the box cover 2 .

[0027] In summary, if Figures 1-5 As shown, the ribbon cassette for a label printing device, when in use, if it is necessary to disassemble the ribbon cassette body 1 and the cassette cover 2, the staff moves the slider 5 and the positioning rod 6 through the paddle 31, so that the outer wall of the positioning rod 6 moves inside the positioning plate 10, and the positioning rod 6 drives the pressure plate 8 to compress one end of the spring 9, and moves one end of the positioning rod 6 out of the positioning slot 7 on the inner wall of the ribbon cassette body 1, and the other end of the positioning rod 6 drives the iron sheet 11 to move to one side of the magnetic sheet 12, and makes the iron sheet 11 and the magnetic sheet 12 magnetically adsorbed together, so as to position the positioning rod 6, (in the present application, the adsorption force when the iron sheet 11 and the magnetic sheet 12 are magnetically adsorbed together is greater than the elasticity of the spring 9), at this time the staff uses the paddle 31 Take the box cover 2 out from the inside of the ribbon box body 1, and drive the back of the box cover 2 to take out the limiting rod 14 from the inside of the limiting tube 13, so that the ribbon box body 1 and the box cover 2 can be disassembled. When installing the box cover 2, move the box cover 2 to the inside of the ribbon box body 1, and insert the limiting rod 14 into the inside of the limiting tube 13, and at the same time make the back of the box cover 2 against the front end of the limiting tube 13, then move the paddle 31 in the opposite direction, and the paddle 31 drives the positioning rod 6 and the iron sheet 11 to move through the slider 5, so that the iron sheet 11 is separated from the magnetic sheet 12, and at the same time use the resilience of the spring 9 to drive the pressure plate 8 and the positioning rod 6 to move, reinsert one end of the positioning rod 6 into the inside of the positioning slot 7, and the box cover 2 can be installed inside the ribbon box body 1.

[0028] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
