[0034] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] In related technologies, the cover plates on many label printers are prone to deformation under stress, causing the left and right ends of the cover plate to not close synchronously, which can easily lead to printing wrinkles during the printing process.

[0036] For the above situation, please refer to Figures 1-4 This application discloses a label printer 100, including a housing 10, a rotating shaft 20, and a cover 30. The housing 10 has a receiving cavity 11 and a first opening 12 communicating with the receiving cavity 11. The cover 30 is rotatably connected to the housing 10 via the rotating shaft 20 to open and close the first opening 12, thereby realizing the opening and closing of the receiving cavity 11. The label printer 100 is used to print characters on label rolls. The label rolls are inserted into the receiving cavity 11 through the first opening 12, and the receiving cavity 11 is used to accommodate the label rolls.

[0037] The cover 30 includes a first cover plate 31 and a second cover plate 32 stacked and connected. The first cover plate 31 is located on the side of the second cover plate 32 away from the receiving cavity 11. That is, when the cover 30 closes the first opening 12, the first cover plate 31 covers the second cover plate 32, and the second cover plate 32 faces the receiving cavity 11. The first cover plate 31 is provided with a first connecting part 33, and the second cover plate 32 is provided with a second connecting part 34. Both the first connecting part 33 and the second connecting part 34 are connected to the rotating shaft 20.

[0038] It is easy to understand that the cover 30 is formed by stacking and combining the first cover plate 31 and the second cover plate 32 to improve the structural strength of the cover 30 itself. The first cover plate 31 and the second cover plate 32 are both connected to the rotating shaft 20 to improve the connection strength between the first cover plate 31 and the second cover plate 32 and the rotating shaft 20, thereby improving the connection strength between the cover 30 and the rotating shaft 20. This makes the cover 30 more stable during rotation and less prone to deformation, thus making the cover 30 and the housing 10 have a better closing effect. This reduces the adverse effects of the cover 30 on printing due to the closing problem, that is, it reduces the probability of printing wrinkles in the label printer 100 during the printing process.

[0039] The first cover plate 31 and the second cover plate 32 can be connected by detachable methods such as screwing, snap-fitting, or magnetic attraction, facilitating their disassembly and making the components between them easy to install and remove, and also aiding in the maintenance of these components. Alternatively, the first cover plate 31 and the second cover plate 32 can be fixedly connected by methods such as welding, gluing, or integral molding; this embodiment does not impose specific limitations on this method.

[0040] It should be noted that, as Figure 1 and Figure 5 As shown, the cover 30 is rotatably connected to the housing 10 via the pivot 20. When the cover 30 is placed over the first opening 12, a paper output channel 13 is formed between the side of the cover 30 away from the pivot 20 and the housing 10. The printed label paper can extend out from the paper output channel 13. A serrated structure 14 is provided on the side wall of the first opening 12 away from the pivot 20. When the cover 30 is closed, the serrated structure 14 and the end of the cover 30 away from the pivot 20 together form the paper output channel 13. The label paper can be torn in the paper output channel 13 by the serrated structure 14. The serrated structure 14 is designed to facilitate the breaking of the printed label paper, making the tearing of the label paper easier.

[0041] In some embodiments, the cover 30 further includes reinforcing ribs (not shown in the figure), which are located between the first cover plate 31 and the second cover plate 32. On the one hand, the setting of reinforcing ribs can improve the overall structural strength of the cover 30 and reduce the risk of deformation of the cover plate as a whole. On the other hand, the setting of reinforcing ribs between the first cover plate 31 and the second cover plate 32 makes the reinforcing ribs not exposed, and the cover 30 itself forms an integral structure, improving the aesthetics of the cover 30.

[0042] The reinforcing ribs can be provided on the first cover plate 31; or, the reinforcing ribs can also be provided on the second cover plate 32; or, the first cover plate 31 and the second cover plate 32 can be provided with reinforcing ribs at the same time, and the reinforcing ribs on the first cover plate 31 and the second cover plate 32 are arranged in an alternating manner to further improve the structural strength of the cover 30, reduce the risk of deformation of the cover 30 itself, and make the closing effect of the cover 30 and the shell 10 better, thereby reducing the probability of printing wrinkles in the label printer 100 during the printing process.

[0043] like Figure 3 As shown, both the first connecting part 33 and the second connecting part 34 are connected to the rotating shaft 20, and the first connecting part 33 and the second connecting part 34 are arranged at intervals along the axial direction of the rotating shaft 20, thereby preventing motion interference between the first connecting part 33 and the second connecting part 34 during the rotation of the cover 30.

[0044] Please seeFigure 3 In some embodiments of this application, a plurality of first connecting portions 33 are provided on the first cover plate 31. The plurality of first connecting portions 33 are arranged at intervals along the axial direction of the rotating shaft 20. The plurality of first connecting portions 33 are all connected to the rotating shaft 20. The provision of the plurality of first connecting portions 33 can improve the connection strength between the first cover plate 31 and the rotating shaft 20, so that the closing effect of the cover 30 and the shell 10 is better.

[0045] Similarly, such as Figure 3 As shown, the second cover plate 32 is provided with a plurality of second connecting parts 34. The plurality of second connecting parts 34 are arranged at intervals along the axial direction of the rotating shaft 20. The plurality of second connecting parts 34 are all connected to the rotating shaft 20. The arrangement of the plurality of second connecting parts 34 can improve the connection strength between the second cover plate 32 and the rotating shaft 20, so that the cover 30 and the housing 10 have a better closing effect.

[0046] For further details, please continue to see Figure 3 In some embodiments of this application, two first connecting parts 33 are provided, and the two first connecting parts 33 are respectively connected to the two ends of the rotating shaft 20. That is, both ends of the rotating shaft 20 are connected to the first cover plate 31. The first connecting parts 33 connecting the first cover plate 31 and the rotating shaft 20 are symmetrically arranged so that the first cover plate 31 can be more stably rotatably connected to the housing 10 through the rotating shaft 20.

[0047] The second connecting part 34 is located between the two first connecting parts 33, the second cover plate 32 is located on the side of the first cover plate 31 facing the receiving cavity 11, and the first connecting parts 33 are located at both ends of the rotating shaft 20. Therefore, the first cover plate 31 can cover the second cover plate 32 and the second connecting part 34, so that when the cover body 30 is closed, the first cover plate 31 can cover the second cover plate 32 and the second connecting part 34, so that the cover body 30 itself forms an integral structure and improves the aesthetics.

[0048] The second connecting part 34 can be provided once, with one second connecting part 34 located between two first connecting parts 33. Alternatively, multiple second connecting parts 34 can be provided, with multiple second connecting parts 34 evenly distributed between two first connecting parts 33. The rotating shaft 20 and the cover 30 are connected through the first connecting parts 33 and the second connecting parts 34, thereby making the connection position between the cover 30 and the rotating shaft 20 evenly and symmetrically distributed, thus improving the connection strength between the cover 30 and the rotating shaft 20, making the closing effect of the cover 30 and the housing 10 better, thereby reducing the probability of printing wrinkles in the label printer 100 during the printing process.

[0049] In some embodiments, the housing 10 is provided with a third connecting part (not shown in the figure), and the rotating shaft 20 is connected to the housing 10 through the third connecting part. The first connecting part 33, the second connecting part 34 and the third connecting part are arranged alternately on the rotating shaft 20. For example, there are two of each of the first connecting part 33, the second connecting part 34 and the third connecting part. The two first connecting parts 33 are respectively connected to the two ends of the rotating shaft 20, the two second connecting parts 34 are located between the two first connecting parts 33, and each third connecting part is located between a first connecting part 33 and a second connecting part 34. This arrangement makes the connection strength between the cover 30 and the housing 10 stronger, and makes the closing effect of the cover 30 and the housing 10 better.

[0050] For further details, please see Figure 4 In some embodiments of this application, the first connecting part 33 is provided with a mounting groove 331, the end of the rotating shaft 20 is inserted into the mounting groove 331, the end of the rotating shaft 20 can contact the bottom wall of the mounting groove 331, and the bottom wall of the mounting groove 331 can limit the rotating shaft 20 along the axis of the rotating shaft 20 to prevent the rotating shaft 20 from moving relative to the axis of the rotating shaft 20.

[0051] like Figure 4 As shown, a through hole 341 is provided on the second connecting part 34, and the rotating shaft 20 passes through the through hole 341. The circumference of the rotating shaft 20 can contact the hole wall of the through hole 341, so that the second connecting part 34 connects the second cover plate 32 to the rotating shaft 20 through the through hole 341, and the second cover plate 32 can also rotate relative to the housing 10 through the rotating shaft 20.

[0052] Please see Figure 4 In some embodiments of this application, a mounting bracket 35 is provided at the end of the second cover plate 32 away from the rotating shaft 20. The mounting bracket 35 and the first cover plate 31 together form a first cavity 351. The label printer 100 also includes a rubber roller 40 for printing labels. The rubber roller 40 is used to apply pressure to the label paper roll located in the receiving cavity 11 to facilitate the printing operation of the label paper roll. The rubber roller 40 is located in the first cavity 351 and is rotatably connected to the mounting bracket 35. The mounting bracket 35 has a second opening 352 communicating with the first cavity 351. When the cover 30 is placed over the first opening 12, the second opening 352 faces the interior of the receiving cavity 11, and a portion of the surface of the rubber roller 40 can contact the label paper roll in the receiving cavity 11 through the second opening 352.

[0053] Specifically, the end of the cover 30 near the rotating shaft 20 is used to drive the entire cover 30 to rotate, so that the cover 30 can be opened or closed. The end of the cover 30 away from the rotating shaft 20 is provided with a rubber roller 40. That is, when the cover 30 is opened, the rubber roller 40 can move away from the housing 10 immediately, thereby preventing pressure from remaining between the rubber roller 40 and the label paper during the opening process. The mounting bracket 35 can provide installation space and a base for the rubber roller 40. The rubber roller 40 is set in the first cavity 351, and the first cavity 351 is formed by the mounting bracket 35 and the first cover plate 31. Therefore, the rubber roller 40 can be disassembled and replaced simply by opening the first cover plate 31 and the second cover plate 32, thereby simplifying the installation and disassembly steps of the rubber roller 40.

[0054] Please see Figure 3 In some embodiments of this application, the label printer 100 further includes a flip-top sensor 50 and a connecting line (not shown in the figure) electrically connected to the flip-top sensor 50. The flip-top sensor 50 is disposed on the cover 30 and can be used to identify the position of the label roll in the receiving cavity 11. When the cover 30 closes the first opening 12, the flip-top sensor 50 can identify the specific position of the label roll. The flip-top sensor 50 can be a photoelectric signal sensor.

[0055] A second cavity (not shown in the figure) is provided between the first cover plate 31 and the second cover plate 32. The label printer 100 also includes an electronic control board. A connecting wire connects the flip sensor 50 and the electronic control board. At least part of the connecting wire is disposed in the second cavity so that the first cover plate 31 and the second cover plate 32 can provide protection for the connecting wire and prevent the connecting wire from getting tangled with the cover 30 during the rotation of the cover 30.

[0056] Furthermore, the connecting wire is fixed to the first cover plate 31 or the second cover plate 32, so that the installation position of the connecting wire is relatively fixed, preventing the connecting wire from shaking between the first cover plate 31 and the second cover plate 32.

[0057] Please see Figure 4 In some embodiments of this application, the label printer 100 further includes an elastic element 60, which is connected to the cover 30 and the housing 10, and is used to assist the cover 30 in opening.

[0058] For example, the housing 10 is provided with a first latching part and a button, and the cover 30 is provided with a second latching part. The first latching part is movably connected to the housing 10 so that the first latching part can engage or disengage with the second latching part. The button is linked to the first latching part. When the cover 30 closes the first opening 12, the elastic member 60 undergoes elastic deformation, and the first latching part engages with the second latching part. The user can press the button to move the first latching part relative to the housing 10, thereby disengaging the first latching part from the second latching part. At this time, there is no force for fixing the cover 30 and the housing 10. The elastic member 60 has an elastic force to restore its deformation, so the cover 30 rotates and opens under the action of this elastic force.

[0059] The elastic element 60 is a torsion spring, which is sleeved on the rotating shaft 20. The first end of the torsion spring is connected to the cover 30, and the second end is connected to the housing 10. When the cover 30 closes the first opening 12, the torsion spring undergoes elastic deformation. When the cover 30 is opened, the torsion spring returns to its original deformation. It should be noted that the first end of the torsion spring is connected to the second cover plate 32 of the cover 30, or the first end of the torsion spring is connected to the side of the first cover 30 facing the second cover 30, and the second end of the torsion spring is connected to the inner wall of the housing 10. This allows the torsion spring to be located inside the label printer 100. Since the cover 30 has a double-layer cover plate structure, the force applied by the torsion spring to the cover 30 is unlikely to cause the cover 30 to bulge outward.
