Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically to a device for adjusting the width of the printer paper tray on a printer to accommodate different sizes of printing paper. Background Technology

[0002] For printing products, such as various common printers, the ability to adapt to different paper widths allows the printer to handle more usage scenarios. Currently, there are two types of adjustable structures on printers on the market to accommodate different paper widths. One type consists of two or more components that achieve sliding limitation by interfering with the housing through a lever or push rod; the other type achieves sliding limitation by the elastic deformation of the lever body inserting into a locking position. The first type usually requires several components, is costly and complex to assemble, and is not easy to operate; the second type is easily limited by material properties, and the structure may fail after fatigue or wear. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a device that can adjust the width of the printer paper tray.

[0004] The technical solution is as follows: A device for adjusting the width of a printer paper tray includes a paper tray and a paper tray baffle. The paper tray baffle includes a base plate movably disposed on the inner bottom surface of the paper tray, and a vertical plate disposed on the base plate for blocking paper. A rotating shaft is provided along the length direction of one side edge of the inner bottom surface. A snap-fit ​​part is provided on one side edge of the base plate and is movably connected to the rotating shaft, and the base plate can rotate relative to the inner bottom surface with the rotating shaft as the axis. A limiting part is also provided on the inner bottom surface, and a limiting member is also provided on the bottom surface of the base plate. In the initial state, the limiting member engages with one of the positions on the limiting part to prevent the base plate from moving on the inner bottom surface.

[0005] Preferably, the limiting part is a rack with several limiting teeth and parallel to the rotating shaft, and the limiting member is trapezoidal and integrally formed with the base plate; the limiting member is engaged with one of the positions on the limiting part, that is, the limiting member is engaged between any two limiting teeth.

[0006] Preferably, the cross-section of the snap-fit ​​part is C-shaped and the snap-fit ​​part is sleeved on the rotating shaft; the snap-fit ​​part can rotate and slide relative to the rotating shaft; the upright plate and the bottom plate are perpendicular to each other and are integrally formed.

[0007] Preferably, the bottom surface of the base plate is also provided with a buckle strip and a guide strip that are parallel to the rotating shaft and integrally formed with the base plate, the buckle strip being located inside the limiting member; the buckle strip is provided with a buckle step along its length.

[0008] Preferably, the inner bottom surface is provided with a guide groove that is combined with the guide strip; the other edge of the inner bottom surface is provided with a fastening part for engaging with the snap-on step.

[0009] Preferably, the inner wall of one end plate of the paper hopper is provided with a recess for accommodating the upright plate, and a lower step is provided on one side wall of the recess.

[0010] Preferably, the back of the upright plate is provided with a recessed portion.

[0011] Preferably, one side of the upright plate is provided with an upper step portion that is adapted to the lower step portion, and when the upright plate enters the recess, the lower step portion and the upper step portion are combined.

[0012] Technical Effects: In this invention, one side of the paper tray baffle is hinged to the inner bottom surface of the paper tray via a rotating shaft, allowing the baffle to slide along the shaft. In the initial state, after the printing paper is placed, the limiting member on the baffle engages with one of the limiting positions, preventing the bottom plate from moving on the inner bottom surface. At this time, the baffle secures the printing paper. When other sizes (widths) of printing paper need to be placed, the upright plate is lifted upwards. The baffle then rotates relative to the inner bottom surface of the paper tray around the rotating shaft, while the other side of the baffle is lifted upwards, disengaging the limiting member from the limiting position. The baffle then moves along the rotating shaft until the distance between the upright plate and one side of the inner wall of the paper tray matches the width of the paper to be replaced. Finally, the other side of the baffle is pressed down, engaging the limiting member with one of the limiting positions, stabilizing the baffle and securing the printing paper. Compared with existing technologies, this invention has a simple structure, low cost, convenient operation, and is unaffected by material fatigue and wear. Attached Figure Description

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 , Figure 3 As shown, this utility model embodiment provides a device for adjusting the width of a printer paper tray, including a paper tray 1 and a paper tray baffle 2. The paper tray baffle includes a base plate 201 movably disposed on the inner bottom surface 101 of the paper tray, and a vertical plate 202 disposed on the base plate for blocking paper. A rotating shaft 3 is provided along the length direction at one side edge of the inner bottom surface. A snap-fit ​​part 201a is provided on one side edge of the base plate 201 and is movably connected to the rotating shaft, and the base plate can rotate relative to the inner bottom surface with the rotating shaft as the axis. A limiting part 4 is also provided on the inner bottom surface, and a limiting member 201b is also provided on the bottom surface of the base plate 201. With this structure, in the initial state, that is, after the printing paper is placed and it is fixed, the limiting member engages with one of the positions on the limiting part to prevent the base plate 201 from moving on the inner bottom surface 101, thereby completing the fixing of the printing paper.

[0020] Specifically, in this embodiment, such as Figure 1 As shown, the limiting part 4 is a rack that includes several limiting teeth and is parallel to the rotating shaft 3. The limiting member 201b is trapezoidal and is integrally formed with the base plate 201, that is, the limiting member is a trapezoidal block; the limiting member is combined with one of the positions on the limiting part, that is, the limiting member 201b is locked between any two limiting teeth.

[0021] like Figures 2-3 As shown, the cross-section of the latching part 201a is C-shaped and the latching part is sleeved on the rotating shaft 3; the latching part can rotate and slide relative to the rotating shaft. If the position of the paper tray baffle 2 needs to be adjusted to adapt to printing paper of different widths (specifications), the other side of the paper tray baffle needs to be lifted up and then slid on the rotating shaft; the upright plate 202 and the bottom plate 201 are perpendicular to each other and the two are integrally formed.

[0022] like Figure 2As shown, to further stabilize the paper tray baffle during paper blocking, the bottom surface of the base plate 201 is also provided with a latching strip 201c and a guide strip 201d that are parallel to the rotating shaft 3 and integrally formed with the base plate. The latching strip is located inside the limiting member 201b; a latching step 2011c is provided along the length of the latching strip. Correspondingly, a guide groove that engages with the guide strip 201d is provided in the inner bottom surface 101; a fastening part 101a for engaging with the latching step 2011c is provided at the other edge of the inner bottom surface.

[0023] like Figure 1 , Figure 4 As shown, when the paper tray baffle 2 needs to be adjusted to the limit position to accommodate the width of the printing paper, that is, the upright plate 202 of the paper tray baffle is in contact with one end plate 102 of the paper tray; the inner wall of one end plate 102 of the paper tray 1 is provided with a recess 102a to accommodate the upright plate 202, and a lower step portion 102b is provided on one side wall of the recess.

[0024] Correspondingly, such as Figure 3 As shown, the back of the upright plate 202 is provided with a recessed portion 202a.

[0025] One side of the upright plate 202 is provided with an upper step portion 202b that corresponds to the lower step portion 102b. When the upright plate enters the recess 102a, the lower step portion and the upper step portion are combined. This allows the upright plate 202 of the paper bin baffle to be tightly combined with one end plate 102 of the paper bin.

[0026] In summary, one side of the paper tray baffle 2 is hinged to the inner bottom surface 101 of the paper tray via a pivot 3, and the paper tray baffle 2 can slide on the pivot 3. In the initial state, that is, after the printing paper is placed, the limiting member 201b on the paper tray baffle 2 engages with one of the positions on the limiting part 4 to prevent the bottom plate 201 from moving on the inner bottom surface. At this time, the paper tray baffle 2 can fix the printing paper. When other sizes (widths) of printing paper need to be placed, the upright plate 202 needs to be lifted upwards. At this time, the paper tray baffle is positioned relative to the paper with the pivot 3 as the axis. The bottom surface 101 of the paper tray rotates, and the other side of the paper tray baffle 2 is lifted upward, causing the limiting member 201b to disengage from the limiting part 4. Then, the paper tray baffle 2 moves along the rotating shaft 3 until the distance between the upright plate 202 and one side of the inner wall of the paper tray is adapted to the width of the printing paper to be replaced. Then, the other side of the paper tray baffle 2 is pressed down, so that the limiting member 201b engages with one of the positions on the limiting part 4, and the snap-fit ​​step 2011c engages with the snap-fit ​​part 101a, so that the paper tray baffle is in a stable state and the printing paper is fixed. The structure of this utility model is simple, low in cost, easy to operate, and unaffected by material fatigue and wear.
