Description

Technical Field

[0001] This utility model relates to the field of printer cover opening technology, and in particular to a novel printer cover opening structure and printer. Background Technology

[0002] Existing thermal printer covers typically integrate many components, resulting in a relatively heavy overall weight. When the printer is used in a side-output scenario (where the printer cover is located on the side), the cover will quickly flip downwards along the opening axis due to the weight of the upper part of the cover and the action of the opening torsion spring. If there is a table or other object under the cover, the cover is prone to colliding with the table, causing damage or displacement of the components inside the cover. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a novel printer cover opening structure and printer, wherein the novel printer cover opening structure includes:

[0004] The printer body has a cover-opening bracket.

[0005] The lid has a rotating arm at one end, which is rotatably connected to the lid opening bracket. The free end of the rotating arm has a protrusion on its side wall, and the free end of the rotating arm is deformable.

[0006] When the cover is closed, there is a gap between the side of the protrusion closest to the printer body and the cover opening bracket in the direction of rotation;

[0007] When the lid is opened, the protrusion can engage with the lid opening bracket and limit the lid to a set opening angle α;

[0008] When the lid is subjected to a pulling force and rotates along the lid opening bracket, the free end of the rotating arm deforms so that the protrusion can pass through the lid opening bracket.

[0009] Preferably, when the free end of the rotating arm deforms, it causes the protrusion to slide on the side wall of the cover-opening bracket.

[0010] Preferably, the top of the protrusion contacts the side wall of the cover-opening bracket.

[0011] Preferably, the thickness of the rotating arm is 1mm-4mm.

[0012] Preferably, the edge of the cover-opening bracket located on the protrusion side has a first chamfer.

[0013] Preferably, the sidewall of the rotating arm is provided with a second chamfer within the distance between the protrusion and the cover opening bracket.

[0014] Preferably, the rotating arm is positioned between two oppositely arranged cover-opening brackets.

[0015] Preferably, the side wall of the cover-opening bracket is provided with reinforcing ribs.

[0016] This utility model also provides a printer that adopts the novel printer cover opening structure described above.

[0017] The novel printer cover opening structure provided by this utility model combines the printer body, cover opening bracket, cover, rotating arm, protrusion, the spacing between the protrusion and the cover opening bracket in the rotation direction, and the deformable free end of the rotating arm. When the top of the cover is unlocked, the cover is popped open and stops rotating at the set opening angle α. Then, the cover can be manually adjusted to the required opening angle. This avoids the problem of damage or displacement of the components inside the cover due to collision with the table during the opening process. In addition, the structure is simple, occupies little space, and is practical. Attached Figure Description

[0028] like Figures 1-6 As shown, this utility model embodiment provides a novel printer cover opening structure and printer, wherein the novel printer cover opening structure includes:

[0029] The printer body 10 has a paper tray opening and a cover opening bracket 11 on one side of the paper tray opening.

[0030] The cover 20 consists of an inner shell 21 and an outer shell 22. One end of a rotating arm 211 is connected to the lower end of the inner shell 21, and the other end of the rotating arm 211 is a free end. The upper end of the inner shell 21 is connected to the printer body 10 through an existing locking connection structure. The rotating shaft 12 passes through the rotating arm 211 and is rotatably connected to the cover opening bracket 11 (e.g., Figure 2 , Figure 5 , Figure 6 As shown), the free end sidewall of the rotating arm 211 is provided with a protrusion 212, and the free end of the rotating arm 211 is deformable;

[0031] When the cover 20 is closed, the side of the protrusion 212 near the printer body 10 and the cover opening bracket 11 are spaced apart in the rotation direction. During manufacturing, the opening angle α can be adjusted by adjusting this distance. The opening angle α can be set according to actual use needs or customer requirements.

[0032] When the lid 20 is opened, the protrusion 212 can engage with the lid opening bracket 11 and limit the lid 20 to a set opening angle α, α < 90 (for example, α can be including but not limited to 3°, 6°, 7°, 10°, 15°, 30°, etc.). At this time, the user manually applies an opening pull force to the lid 20. When the lid 20 is pulled and rotates along the rotational connection with the lid opening bracket 11, the free end of the rotating arm 211 is squeezed and deformed, allowing the protrusion 212 to pass through the lid opening bracket 11.

[0033] The structure of the printer body 10 and cover 20 described above is the existing structure of thermal printers, and their working principles are all existing technologies, which will not be described in detail here.

[0034] The novel printer cover opening structure provided in this embodiment of the invention, through the design of the printer body 10, cover opening bracket 11, cover 20, rotating arm 211, protrusion 212, and the spacing between the cover opening bracket 11 in the rotation direction, and the deformable free end of the rotating arm 211, allows the cover 20 to spring open and stop rotating at a set opening angle α after the upper end of the cover 20 is unlocked. The cover 20 can then be manually adjusted to the desired opening angle, thus avoiding damage or displacement of internal components caused by the cover 20 colliding with the desktop during opening. Furthermore, the structure is simple and occupies little space.

[0035] Furthermore, when the free end of the rotating arm 211 deforms, it causes the protrusion 212 to slide on the side wall of the cover-opening bracket 11.

[0036] In practice, the lid-opening bracket 11 is a plate-like structure. When the free end of the rotating arm 211 deforms, it causes the protrusion 212 to slide on the side wall of the lid-opening bracket 11. When the lid 20 is subjected to tension, the deformation of the rotating arm 211 causes the protrusion 212 to contact the side wall of the lid-opening bracket 11. At this time, friction is generated between the surface of the protrusion 212 and the side wall of the lid-opening bracket 11, which can provide continuous friction for the lid 20 during the manual opening process. This facilitates manual positioning of the final opening angle and avoids the problem of the lid 20 suddenly losing resistance and hitting the table when it is released.

[0037] Furthermore, the top of the protrusion 212 contacts the side wall of the cover-opening bracket 11.

[0038] In specific implementation, the top of the protrusion 212 is a rectangular plane, and the top of the protrusion 212 contacts the side wall of the cover opening bracket 11. Through the surface contact structure design, the thickness of the rotating arm 211 and the friction required by the limiting cover 20 can be balanced. Compared with point or line contact, it can reduce the thickness required by the rotating arm 211 while providing sufficient friction.

[0039] Furthermore, the thickness of the rotating arm 211 is 1mm-4mm.

[0040] In practice, the thickness of the rotating arm 211 is 1mm-4mm, such as 1.5mm or 2.5mm. Within this range, the user's opening experience is optimal.

[0041] Furthermore, the edge of the cover-opening bracket 11 located on one side of the protrusion 212 is provided with a first chamfer 111.

[0042] Furthermore, the side wall of the rotating arm 211 is provided with a second chamfer 213 within the distance between the protrusion 212 and the cover opening bracket 11.

[0043] In specific implementation, such as Figure 2 , Figure 3 As shown, the opening bracket 11 has a first chamfer 111 on the edge of the protrusion 212, and the side wall of the rotating arm 211 has a second chamfer 213 within the distance between the protrusion 212 and the opening bracket 11. The design of the first chamfer 111 and the second chamfer 213 makes it easy for the protrusion 212 to enter the side wall of the opening bracket 11.

[0044] Furthermore, the rotating arm 211 is disposed between two oppositely arranged cover-opening brackets 11.

[0045] In specific implementation, there are two cover-opening brackets 11, which are arranged opposite to each other for mounting the rotating shaft 12. By setting the rotating arm 211 between the two cover-opening brackets 11, compared with setting it on the outside of the cover-opening brackets 11, setting it on the cover-opening brackets 11 can provide sufficient space for the deformation of the free end of the rotating arm 211 and reduce the impact on other components.

[0046] Furthermore, the side wall of the cover-opening bracket 11 is provided with reinforcing ribs 112.

[0047] In specific implementation, such as Figure 5 As shown, the side wall of the cover opening bracket 11 is provided with several reinforcing ribs 112, which strengthen the strength of the cover opening bracket 11.

[0048] This utility model embodiment also provides a printer that adopts the novel printer cover opening structure described above.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
