Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 to 4, a quick-dismantling structure for a printing roll paper baffle is shown, which is arranged on a roll paper baffle 10, and comprises a notch 11 formed on the upper surface of the roll paper baffle 10 and extending to a shaft hole 30 along the radial direction, one end of the roll paper baffle 10 is further provided with a quick-dismantling part 12, the quick-dismantling part 12 and the roll paper baffle 10 are integrally formed, the notch 11 extends along the axis with the shaft hole 30 to penetrate through the quick-dismantling part 12, a side surface of the quick-dismantling part 12 corresponding to the notch 11 is provided with a yielding groove 15 and a compressing position 16, a side surface of the quick-dismantling part 12 corresponding to the yielding groove 15/compressing position 16 is connected with a quick-dismantling handle 13, the inner side of the quick-dismantling handle 13 is provided with a protruding part 14, the protruding part 14 can rotate along with the quick-dismantling handle 13 relative to the quick-dismantling part 12, so that the protruding part 14 is positioned at the compressing position 16 and contracts the notch 11, and then a bracket shaft 20 can be fastened in the shaft hole 30, the pressing force of the protruding part 14 on the notch 11 is further rotated along with the shaft hole 12 relative to the yielding groove 15, at this time, namely the bracket shaft 20 is loosened, and the bracket shaft 20 can be removed from the shaft hole 30 in a simple and the replacement mode compared with the existing roll paper structure.
In some possible implementation manners, the quick-release handle 13 is in a U-shaped structure, two ends of the quick-release handle 13 are respectively connected to two opposite sides of the quick-release portion 12, the two opposite sides of the quick-release portion 12 are respectively provided with a yielding groove 15 and a pressing position 16, two ends of the quick-release handle 13 are correspondingly provided with protruding portions 14, in this embodiment, when the two protruding portions 14 are arranged in a mirror image mode and rotate to the pressing position 16, pressure can be applied to two ends of the notch 11 at the same time, and the problem that the notch 11/shaft hole 30 is deformed and shifted too much is avoided.
In some possible implementation manners, two ends of the quick-release handle 13 are rotatably connected with the quick-release portion 12 through a rotating shaft 17, the rotating shaft 17 horizontally penetrates through the notch 11, in this embodiment, the rotating shaft 17 plays a role in connecting the quick-release handle 13 and the quick-release portion 12, it is to be noted that a through hole capable of allowing the rotating shaft 17 to penetrate through is arranged on the quick-release portion 12, the aperture of the through hole is larger than the outer diameter of the rotating shaft 17, and the problem that the rotating shaft 17 cannot rotate due to small deformation caused by shrinkage of the notch 11 is avoided.
In some possible implementations, the protrusion 14 is hemispherical, so as to ensure that the protrusion 14 can rotate along with the quick release handle 13 and rotate from the relief groove 15 to the pressing position 16, and when the protrusion 14 passes over the side edge of the relief groove 15 in this embodiment, the quick release portion 12/the roll paper baffle 10 deforms to shrink the notch 11.
In some possible implementations, the relief groove 15 is located below the pressing portion 16, and when the protrusion 14 presses the pressing portion 16 to fix the bracket shaft 20, the quick release handle 13 rotates to the lower end, so as to avoid that the quick release handle protrudes from the upper surface of the paper rolling baffle 10 to affect the appearance.
The foregoing is merely illustrative of specific embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any changes or substitutions within the technical scope of the present utility model should be covered by the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
