[0027] This utility model provides a novel printer cover opening hook and locking structure, and a printer. The novel printer cover opening hook includes a first hook component 10. The first hook component 10 is provided with a first hook part 11, a button contact part 12 and a first reset mounting part 13.

[0028] The button contact portion 12 is disposed adjacent to one side of the first hook portion 11;

[0029] The surface of the button contact portion 12 that contacts the button 30 is provided with a protrusion 121;

[0030] The first reset mounting part 13 is used to mount the first reset mechanism 50.

[0031] In specific implementation, such as Figure 1 , Figure 2 As shown, the new printer cover opening hook includes a first hook 10; the first hook 10 has a plate-like structure and is provided with a first hook part 11, a button contact part 12 and a first reset mounting part 13.

[0032] like Figure 2 As shown, the first hook portion 11 has a hook-shaped structure. The first hook portion 11 is located at the upper end of the first hook member 10, and the lower end of the first hook member 10 is connected to the housing shaft of the printer body. The first hook portion 11 is used to secure the printer's rubber roller. The combination of the first hook portion 11 and the rubber roller is prior art and will not be described in detail here.

[0033] The button contact part 12 is located on the side of the first hook part 10 adjacent to the first hook part 11; compared with setting it in other positions by adding external parts, it occupies less space.

[0034] The surface of the button contact portion 12 that contacts the button 30 has a protrusion 121; the upper surface of the protrusion 121 abuts against the lower end of the button 30, which makes the button 30 smoother during the pressing process compared to the flat structure, thus providing a better user experience.

[0035] The first reset mounting part 13 is used to install the first reset mechanism 50, which is a torsion spring, tension spring, etc.

[0036] like Figure 5 As shown, this is the initial state, where the first hook 11 engages with the rubber roller. When the user presses button 30, button 30 acts on button contact part 12 through protrusion 121, pressing button contact part 12 downward. Button contact part 12 rotates along the shaft connected to the housing shaft of the printer body, causing the first hook 11 to rotate and release the rubber roller. The rubber roller is integrated on the top cover of the printer, and the top cover can be opened when the rubber roller is released.

[0037] The novel printer cover opening hook provided in this embodiment has a compact structure, which reduces the space occupied by this part of the structure inside the printer, provides a good foundation for the installation and miniaturization of other parts, and can provide users with a good button usage experience.

[0038] Preferably, the protrusion 121 is elongated, and its length direction is parallel to the length direction of the rotating shaft 40.

[0039] Furthermore, the surface of the button contact portion 12 for contacting the button 30 is provided with two or more protrusions 121, and the protrusions 121 are arranged sequentially along the horizontal projection of the rotation direction.

[0040] In specific implementation, such as Figure 5 As shown, the surface of the button contact portion 12 that contacts the button 30 has two or more protrusions 121. The protrusions 121 are elongated, and their length direction is parallel to the length direction of the rotating shaft 40. The protrusions 121 are arranged sequentially along the horizontal projection of the rotation direction. This structure makes the button 30 smoother and more fluid when pressed, further reducing the phenomenon of jamming.

[0041] Preferably, the height of the protrusion 121 near the first latch portion 11 is lower than the height of the protrusion 121 away from the first latch portion 11. This structure can reduce the torque offset of the structure during the pressing of the button 30, thereby improving the user experience.

[0042] Furthermore, a clearance space 122 is provided on one side of the button contact portion 12.

[0043] In specific implementation, such as Figure 4 As shown, the first hook 10 has a plate-like structure, and the button contact part 12 protrudes from one side of the plate surface of the first hook 10, and is located on the first hook 10 (e.g. Figure 2 As shown, a clearance space 122 is formed on the left side to provide sufficient installation space for the button 30, thereby reducing the interference of the installation of the button 30 with other parts of the printer.

[0044] Furthermore, the button contact portion 12 is integrated with the first hook component 10.

[0045] In specific implementation, the button contact part 12 and the first hook part 10 are integrally made of the same material, including but not limited to plastic, metal and alloy.

[0046] This utility model embodiment also provides a locking structure, which adopts the novel printer cover opening hook as described above, and further includes a second hook member 20. The second hook member 20 includes a second hook portion 21 and a second reset mounting portion 22; the second reset mounting portion 22 is used to install the second reset mechanism 60.

[0047] The second hook 20 is arranged parallel to the first hook 10; the second hook 20 and the first hook 10 are connected by a rotating shaft 40.

[0048] In specific implementation, such as Figure 2 , Figure 3 As shown, the locking structure adopts any of the above-mentioned new printer cover opening hooks, and also includes a second hook component 20. The second hook component 20 includes a second hook part 21 and a second reset mounting part 22; the second reset mounting part 22 is used to install the second reset mechanism 60.

[0049] The second hook 20 is arranged parallel to the first hook 10; the second hook 20 and the first hook 10 are connected by a pivot 40.

[0050] The first hook part 11 and the second hook part 21 are respectively used to engage with the two sides of the shaft of the printer's rubber roller (not shown in the figure). Compared with securing the rubber roller with a single hook, the securing structure of two hooks can provide a more stable securing connection.

[0051] When the cover is opened, the first hook 10 and the second hook 20 can be rotated along the rotating shaft 30 simultaneously by pressing the button 30 through the connection of the rotating shaft 40, thereby releasing the rubber roller from the first hook 11 and the second hook 21.

[0052] When the user releases button 30, the first reset mechanism 50 pulls the first latch 10 and the second reset mechanism 60 pulls the second latch 20 back to the initial position, completing the reset.

[0053] The locking structure provided in this embodiment of the invention can provide a more stable locking connection for the rubber roller.

[0054] The first reset mechanism 50 and the second reset mechanism 60 are torsion springs or tension springs, or a combination of torsion springs and tension springs. During installation, one end of the tension spring or torsion spring is connected to the side wall of the first hook 10 or the side wall of the second hook 20, and the other end of the tension spring or torsion spring is connected to the printer housing.

[0055] like Figure 2 , Figure 3 As shown, the first reset mechanism 50 is a torsion spring, and the second reset mechanism 60 is a tension spring. Tension springs can provide greater tensile force, but in actual installation, a larger installation space needs to be reserved for them. When the installation space for the first reset mechanism 50 or the second reset mechanism 60 is limited, and a larger reset tensile force is required, a structure combining a torsion spring and a tension spring is used. This allows the tension spring to assist in the reset, providing sufficient reset tensile force. Furthermore, the installation space required for the tension spring is smaller than that for the torsion spring, thus meeting the installation requirements.

[0056] Furthermore, the side walls of both the first hook 10 and the second hook 20 are provided with reinforcing ribs.

[0057] In specific implementation, such as Figure 2 As shown, the first hook 10 has a first reinforcing rib 14 on its side wall, and the second hook 20 has a second reinforcing rib 23 on its side wall. The strength of the first hook 10 and the second hook 20 is improved by the reinforcing ribs.

[0058] This utility model embodiment also provides a printer that uses any of the novel printer cover opening hooks described above.

[0059] Furthermore, button 30 and the paper tray opening 71 of the printer body are located on the same side.

[0060] 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.
