[0041] Embodiment 1

[0042] In order to solve the problem that the setting of the locking structure in the prior art leads to the complex overall structure of the baffle structure and the paper bin, complicated operation and increased cost, and poor user experience, this embodiment provides a paper bin baffle structure. The paper bin baffle structure is used to be installed inside the paper bin of the printing device.

[0043] like Figures 1 to 7As shown, the paper bin baffle structure includes a frame 10 and a rotating member 20. The frame 10 can be installed inside the paper bin. The frame 10 includes a first baffle 110. The end of the first baffle 110 close to the bottom of the paper bin has an arch structure 112 that can undergo elastic deformation. The frame 10 also includes at least one arm 113 connected to the arch structure 112. The rotating member 20 is rotatably connected to the frame 10. The first end of the rotating member 20 can contact the arch structure 112. The rotating member 20 can slide on the arched outer curved surface of the arch structure 112. The rotating member 20 has a first position for driving the arch structure 112 to undergo elastic deformation. The rotating member 20 also has a second position that does not cause the arch structure 112 to undergo elastic deformation. The rotating member 20 switches between the first position and the second position.

[0044] The paper bin baffle structure of the present application adopts an elastically deformable arch structure 112 disposed on the frame 10, so that the arch structure 112 can drive the arm 113 to move after elastic deformation, and then the paper bin baffle structure and the paper bin are locked and matched through the arm 113. When the first end of the rotating member 20 in the first position presses the arch structure 112, under the action of the restoring force of the arch structure 112, the second end of the rotating member 20 remains in contact with the frame 10, and the rotating member 20 is locked in the first position.

[0045] Specifically, the paper bin baffle structure of the present application is provided with an elastically deformable arch structure 112 on the frame 10. The arch structure 112 can not only lock the rotating part 20 in the first position; the arch structure 112 also has the function of locking the arm 113 and the paper bin. The overall structure is simple, the operation is simple, the production cost is reduced, and the user experience is improved.

[0046] Furthermore, the present application drives the rotating member 20 to switch between the first position and the second position, which is simple to operate; when the rotating member 20 rotates to the first position, the rotating member 20 can remain relatively fixed with the frame 10, and at this time the arm 113 is locked with the paper bin, so that the paper bin baffle structure is fixed inside the paper bin.

[0047] Furthermore, the rotating member 20 is rotatably connected to the first baffle 110. Specifically, the rotating member 20 is rotatably connected to an end of the first baffle 110 away from the bottom of the paper bin.

[0048] It should be noted that the first end of the rotating member 20 can slide along the outer curved surface of the arch structure 112. When the rotating member 20 switches between the first position and the second position, the rotating member 20 and the outer curved surface of the arch structure 112 are only in contact without being squeezed, or the rotating member 20 and the outer curved surface of the arch structure 112 are squeezed.

[0049] In this embodiment, when the rotating member 20 rotates to the first position, the first end of the rotating member 20 slides to abut against the outer arc surface of the arched top of the arched structure 112 to drive the arched structure 112 to undergo elastic deformation, and the two arched ends of the arched structure 112 are relatively far away from each other; when the rotating member 20 switches to the second position, the first end of the rotating member 20 is away from the arched top of the arched structure 112, and the two arched ends of the arched structure 112 are reset.

[0050] After the outer arc surface of the arched top of the arched structure 112 of the present application is squeezed by the first end of the rotating member 20, the arched structure 112 will undergo elastic deformation, and the arched structure 112 will undergo elastic deformation toward the bottom of the paper bin, and the two ends of the arched structure 112 will move in directions away from each other, that is, the two ends of the arch will expand. At this time, the arched structure 112 will drive the arm 113 to displace, and the displaced arm 113 can be locked with the paper bin; when the arched structure 112 is released from the squeezing force of the first end of the rotating member 20, that is, when the rotating member 20 is in the second position, the arched structure 112 returns to its original position under the action of the restoring force, and the two ends of the arched structure 112 approach each other to achieve resetting.

[0051] In this embodiment, the arm portion 113 is an arc-shaped plate structure, and the arm portion 113 extends toward a side away from the rotating member 20. According to different numbers of the arm portions 113, the following three implementation modes are provided.

[0052] like Figure 1 In the specific embodiment shown, two arms 113 are provided, the two arms 113 are arranged at intervals, and the two arms 113 are respectively arranged at two ends of the arch of the arch structure 112 .

[0053] Specifically, the arch structure 112 is elastically deformed under the abutment of the rotating member 20, that is, the arch structure 112 is deformed under force to open the two arms 113, and the two arms 113 in the open state are locked with the paper bin to fix the paper bin baffle structure. The provision of two arms 113 is conducive to enhancing the stability of the locking of the arms 113 with the paper bin.

[0054] In a specific embodiment shown in the figure, one arm portion 113 is provided, and the arm portion 113 is provided at one of the two ends of the arch structure 112 .

[0055] Specifically, the arch structure 112 is elastically deformed under the abutment of the rotating member 20, that is, the arch structure 112 is deformed under force to lock the arm 113 with the paper bin to fix the paper bin baffle structure. Among them, by providing one arm 113, the overall structure is simple, which is conducive to reducing production costs.

[0056] In another specific embodiment shown in the figure, an arm 113 is provided, and the arm 113 is a third baffle connected to the first baffle 110, and a groove is provided in the middle of the third baffle. The arm 113 and the first baffle 110 are roughly at a right angle, and the third baffle is arranged on the first baffle 110 as an integral plate structure.

[0057] Specifically, the arm 113 has a sufficient extension length. When the arch structure 112 is deformed under force, both ends of the arch structure 112 simultaneously drive the arm 113 to deform, thereby achieving locking of the arm 113 with the paper bin. A groove is opened in the middle of the third baffle to facilitate the deformation of the third baffle under force.

[0058] like Figure 1 and Figure 2 As shown, the rotating member 20 is rotationally connected to the first baffle 110 , and the position of the rotational connection, the vertex of the arch structure 112 and the center of the virtual circle where the arch structure 112 is located are not colinear.

[0059] In this embodiment, the position where the rotating member 20 is rotatably connected to the first baffle 110 is eccentrically arranged with respect to the center of the virtual circle where the arch structure 112 is located, so that when the rotating member 20 is switched between the first position and the second position, when the rotating member is in the first position, the rotating member abuts against the apex of the arch structure 112 to squeeze the arch structure 112 to deform.

[0060] In this embodiment, the paper bin baffle structure also includes a first limiting structure 30 and a second limiting structure 40. The rotating shaft 220 and the rotating hole 121 are limited by the first limiting structure 30 and the second limiting structure 40. The first limiting structure 30 is arranged on the rotating shaft 220, and the second limiting structure 40 is arranged on the first baffle 110. The second limiting structure 40 is formed at the rotating hole 121. One of the first limiting structure 30 and the second limiting structure 40 is a rotating groove, and the other is a protruding structure. The protruding structure can rotate inside the rotating groove.

[0061] The first limiting structure 30 and the second limiting structure 40 cooperate to not only limit the rotation angle of the rotating member 20, but also prevent the rotating member 20 from being disengaged. By setting the relative limiting position of the rotating member 20, it is beneficial to improve the convenience of operation and the stability of the rotation of the rotating member 20.

[0062] Furthermore, the protruding structure can be rotated inside the rotating groove, thereby enabling the rotating member 20 to rotate at a preset rotation angle.

[0063] Furthermore, the protruding structures and the rotating grooves are arranged in a one-to-one correspondence. When a plurality of protruding structures are provided, the plurality of protruding structures are arranged at intervals along the circumference of the rotating hole 121 .

[0064] Preferably, two protrusion structures are provided, which are arranged at an interval of 180° along the circumference of the rotating hole 121 .

[0065] In a specific implementation of this embodiment, the protrusion structure is arranged on the rotating shaft 220, the rotating groove is arranged on the first baffle 110 and is connected to the rotating hole 121, the protrusion structure rotates with the rotating shaft 220, and the rotating groove limits the rotation angle of the rotating shaft 220 by limiting the position of the protrusion structure.

[0066] In another specific implementation of this embodiment, the protrusion structure is arranged on the first baffle 110, the rotation groove is arranged on the rotating shaft 220 and is connected to the rotating hole 121, the rotation groove rotates with the rotating shaft 220, and the rotation angle of the rotating shaft 220 is limited by limiting the position of the protrusion structure through the rotation groove.

[0067] Furthermore, a deformation groove is provided in the middle of the first baffle 110 , and the arched structure 112 is formed below the deformation groove, and the arched outer arc surface of the arched structure 112 is formed as the groove wall surface of the lower edge of the deformation groove.

[0068] Specifically, the first baffle 110 includes a baffle portion 111 and an arched structure 112. The baffle portion 111 is an arc-shaped structure, and a deformation groove is provided on the baffle portion 111. The baffle portion 111 has an arc-shaped surface facing the side of the roll paper. The arched structure 112 of the present application is integrally formed with the baffle portion 111. When the arched structure 112 undergoes elastic deformation, the deformation groove on the baffle portion 111 expands.

[0069] Furthermore, the arch structure 112 is formed below the deformation groove, and when the arch structure 112 undergoes elastic deformation, the deformation groove expands.

[0070] In this embodiment, the deformation groove can cooperate with the arched outer curved surface of the arched structure 112, so that when the arched outer curved surface is deformed, the deformation groove is deformed accordingly, thereby improving the use efficiency.

[0071] like Figure 1 and Figure 2 As shown, the deformation groove includes a first deformation groove 1111 and a second deformation groove 1112 which are connected and arranged at an angle.

[0072] Specifically, the first deformation groove 1111 and the second deformation groove 1112 expand when the arch structure 112 is squeezed by the rotating member 20 , thereby enabling the arch structure 112 to drive the arm portion 113 to move.

[0073] Furthermore, the second deformation groove 1112 extends in the same direction as the arch structure 112 , that is, the second deformation groove 1112 extends along the deformation direction of the arch structure 112 , so that under the extrusion of the rotating member 20 , the second deformation groove 1112 can be expanded to elastically deform toward the bottom of the paper bin.

[0074] Furthermore, by providing the first deformation groove 1111 , the two ends of the arch structure 112 can be opened in directions away from each other.

[0075] Furthermore, the first deformation groove 1111 extends along the height direction of the baffle portion 111 .

[0076] Furthermore, the second deformation groove 1112 is arranged at one end of the first deformation groove 1111 facing the bottom of the paper bin, and the second deformation groove 1112 is arranged close to the arch structure 112, which is conducive to the elastic deformation of the arch structure 112.

[0077] Furthermore, the middle regions of the first deformation groove 1111 and the second deformation groove 1112 are connected, which is beneficial to improving the stability of deformation and the stability of the overall structure.

[0078] In this embodiment, the arch structure 112 has a raised step on one side facing the rotating member 20 , the first end of the rotating member 20 is in contact with the raised step, and the raised step has an arched outer curved surface.

[0079] Specifically, the first end of the rotating member 20 contacts the raised step. When the rotating member 20 is in the first position, the first end of the rotating member 20 squeezes the raised step and undergoes elastic deformation. When the rotating member 20 is in the second position, the first end of the rotating member 20 contacts the raised step and does not undergo elastic deformation.

[0080] The raised step is not limited to the above-mentioned arched structure 112. In another embodiment, the first end of the rotating member 20 has a convex column, which extends toward the first baffle 110, and at least a portion of the convex column contacts the outer arc surface of the arch. At this time, the convex column can contact the exposed outer arc surface of the arch, and the convex column squeezes the outer arc surface of the arch, or the convex column only contacts the outer arc surface of the arch without squeezing the outer arc surface of the arch. The convex column can extend into the interior of the deformation groove, and the convex column contacts the surface where the lower edge of the notch of the deformation groove is located, that is, the surface where the lower edge of the notch of the deformation groove is located is the outer arc surface of the arch.

[0081] Embodiment 2

[0082] Different from the first embodiment, Figure 1 As shown, in this embodiment, the frame body 10 further includes a second baffle plate 120 , and the rotating member 20 is rotatably connected to the second baffle plate 120 .

[0083] The second baffle plate 120 is disposed on one side of the first baffle plate 110 , and the second baffle plate 120 is connected to a side edge of the first baffle plate 110 . The first baffle plate 110 and the second baffle plate 120 are substantially parallel to form a mounting groove 101 .

[0084] Specifically, the first baffle 110 and the second baffle 120 are connected, and the first baffle 110 and the second baffle 120 cooperate to form a mounting groove 101. The first end of the rotating member 20 is arranged inside the mounting groove 101, and the mounting groove 101 provides space for the rotating member 20 to rotate.

[0085] The frame 10 has a mounting groove 101 , and one end of the frame 10 close to the bottom of the paper bin has an elastically deformable arch structure 112 , and the rotating member 20 is rotatably connected to the second baffle 120 .

[0086] Furthermore, the rotational connection position of the rotating member 20 and the second baffle 120 is not colinear with the projection position in the plane where the first baffle 110 is located, the center of the virtual circle where the arch structure 112 is located, and the vertex of the arch structure 112. That is, the rotational connection position of the rotating member 20 and the second baffle 120 is not on the extension line of the line connecting the center of the virtual circle where the arch structure 112 is located and the vertex in the middle of the arch structure 112, that is, it is eccentrically arranged.

[0087] like Figure 5 and Figure 6 As shown, the rotating hole 121 is eccentrically arranged on the second baffle 120 to realize that during the rotation of the rotating member 20, when the rotating member 20 is in the first position, the first end of the rotating member 20 abuts against the outer arc surface of the arched top of the arched structure 112 to extrude the arched structure 112 to cause elastic deformation, and the second end of the rotating member 20 abuts against a groove side wall of the groove opening area of ​​the mounting groove 101; when the rotating member 20 switches to the second position, the first end of the rotating member 20 is away from the arched top of the arched structure 112, the first end of the rotating member 20 releases the extrusion of the arched structure 112, and the second end of the rotating member 20 contacts another groove side wall of the groove opening area of ​​the mounting groove 101.

[0088] Among them, the eccentrically arranged rotating member 20 can be tilted when the rotating member 20 is in the first position. At this time, the rotating member 20 is subjected to the restoring force of the arch structure 112 and the limiting action of the frame 10, and the rotating member 20 and the frame 10 abut against each other to maintain a relatively fixed locked state.

[0089] Furthermore, the crank 210 has an abutment end 212 located inside the mounting groove 101 and an operating end 211 exposed outside the mounting groove 101, and the abutment end 212 has an avoidance slope 2122 and an abutment surface 2121. When the rotating member 20 is in the first position, the abutment surface 2121 abuts against the arch structure 112 to squeeze the arch structure 112 to cause elastic deformation. When the rotating member 20 switches to the second position, the avoidance slope 2122 contacts the arch structure 112 and does not cause elastic deformation.

[0090] Specifically, the operating end 211 is used to realize the rotation of the rotating member 20 between the first position and the second position after being subjected to external force; the abutment end 212 is used to abut against the arch structure 112, thereby realizing that when the rotating member 20 is in the first position, the abutment end 212 can drive the arch structure 112 to undergo elastic deformation.

[0091] In this embodiment, the avoidance slope 2122 is provided to avoid the arch structure 112, so as to avoid deformation of the arch structure 112. The abutment surface 2121 is used to squeeze the arch structure 112. When the rotating member 20 is in the first position, the abutment surface 2121 abuts against and squeezes the outer arc surface of the arch top of the arch structure 112, so as to realize elastic deformation of the arch structure 112 and drive the arm 113 to open.

[0092] like Figures 1 to 7 As shown, the rotating member 20 includes a crank 210 at least partly disposed inside the mounting groove 101 and a rotating shaft 220 disposed on the crank 210 . The second baffle 120 has a rotating hole 121 , and the rotating shaft 220 and the rotating hole 121 are rotatably matched.

[0093] Specifically, the rotating member 20 is rotatably connected to the second baffle 120, and the rotating member 20 squeezes the first baffle 110 during rotation, so that the paper bin baffle structure and the paper bin are relatively fixed through the deformation of the first baffle 110, and when the rotating member 20 abuts against the first baffle 110, the rotating member 20 is relatively fixed on the frame 10.

[0094] Furthermore, the crank 210 is rotated to achieve the abutment or release of the abutment between the first end of the rotating member 20 and the arch structure 112 so as to only contact the first end of the rotating member 20 .

[0095] Among them, a structure in which the rotating shaft 220 and the rotating hole 121 cooperate is adopted. When the rotating member 20 is in the first position, the arch structure 112 provides a restoring force to drive the rotating member 20 to move. The positions of the rotating shaft 220 and the rotating hole 121 play a limiting role to overcome the restoring force. At the same time, the first baffle 110 also provides a corresponding supporting force to overcome the restoring force, thereby achieving that when the rotating member 20 is in the first position, the rotating member 20 remains in contact with the frame 10 and is in a relatively fixed locked state.

[0096] In this embodiment, the paper bin baffle structure also includes a first limiting structure 30 and a second limiting structure 40. The rotating shaft 220 and the rotating hole 121 are limited by the first limiting structure 30 and the second limiting structure 40. The first limiting structure 30 is arranged on the rotating shaft 220, and the second limiting structure 40 is arranged on the second baffle 120. The second limiting structure 40 is formed at the rotating hole 121. One of the first limiting structure 30 and the second limiting structure 40 is a rotating groove, and the other is a protruding structure. The protruding structure can rotate inside the rotating groove.

[0097] The first limiting structure 30 and the second limiting structure 40 cooperate to not only limit the rotation angle of the rotating member 20, but also prevent the rotating member 20 from being disengaged. By setting the relative limiting position of the rotating member 20, it is beneficial to improve the convenience of operation and the stability of the rotation of the rotating member 20.

[0098] Furthermore, the protruding structure can be rotated inside the rotating groove, thereby enabling the rotating member 20 to rotate at a preset rotation angle.

[0099] Furthermore, the protruding structures and the rotating grooves are arranged in a one-to-one correspondence. When a plurality of protruding structures are provided, the plurality of protruding structures are arranged at intervals along the circumference of the rotating hole 121 .

[0100] Preferably, two protrusion structures are provided, which are arranged at an interval of 180° along the circumference of the rotating hole 121 .

[0101] In a specific implementation of this embodiment, the protrusion structure is arranged on the rotating shaft 220, the rotating groove is arranged on the second baffle 120 and is connected to the rotating hole 121, the protrusion structure rotates with the rotating shaft 220, and the rotating groove limits the rotation angle of the rotating shaft 220 by limiting the position of the protrusion structure.

[0102] In another specific implementation of this embodiment, the protrusion structure is arranged on the second baffle 120, the rotation groove is arranged on the rotating shaft 220 and is connected to the rotating hole 121, the rotation groove rotates with the rotating shaft 220, and the rotation angle of the rotating shaft 220 is limited by limiting the position of the protrusion structure through the rotation groove.

[0103] like Figure 1 and Figure 2 As shown, the arm 113 has a limiting rib 1131 at least a portion of which extends into the limiting groove of the paper bin. When the rotating member 20 is in the first position, the limiting rib 1131 abuts against the inner wall surface of the limiting groove. When the rotating member 20 is in the second position, the limiting rib 1131 is slidably set inside the limiting groove.

[0104] Among them, when the rotating part 20 is in the first position, the limiting rib 1131 moves toward the inner wall of the limiting groove and abuts against the inner wall of the groove, so as to achieve locking with the paper bin through friction, so as to achieve relative fixation of the paper bin baffle structure and the paper bin; when the rotating part 20 is in the second position, the arm 113 moves with the arch structure 112 and retracts and resets. After retracting and resetting, the arm 113 can release the locking of the paper bin baffle structure and the paper bin, and at this time the paper bin baffle structure can slide inside the paper bin.

[0105] Embodiment 3

[0106] Different from the first embodiment, the frame body further includes a second baffle plate 120 , the rotating member 20 is rotatably connected to the second baffle plate 120 , and the deformation groove is a U-shaped groove that is open at the top of the first baffle plate 110 .

[0107] It can be understood that the first baffle 110 is generally in a U-shaped structure with an open top, and the specific formation of the deformation groove can be adaptively set, with the top of the deformation groove being an open structure.

[0108] In this embodiment, after the arch structure 112 undergoes elastic deformation, the deformation groove can be easily expanded, which is beneficial for the movement of the arm 113 and thus improves the convenience of operation.

[0109] Embodiment 4

[0110] Different from the first embodiment, the deformation groove is formed at the center of the first baffle plate 110 so that the first baffle plate 110 has a frame-shaped structure.

[0111] In this embodiment, one deformation groove is provided, and the deformation groove may be a polygonal groove such as a rectangular groove, a triangular groove, or a groove of other irregular shapes.

[0112] Embodiment 5

[0114] In this embodiment, the printing device also includes a paper bin, and the paper bin baffle structure is slidably set inside the paper bin, and the paper bin has a limiting groove. At least a portion of the limiting rib 1131 of the arm 113 of the paper bin baffle structure is located inside the limiting groove, and the limiting rib 1131 is abutted and locked with the inner surface of the limiting groove or the limiting rib 1131 is slidably set inside the limiting groove.

[0115] In this embodiment, the paper bin baffle structure of the printing device slides to a preset position inside the paper bin to adapt to different papers. The paper bin baffle structure can slide inside the limiting groove through the limiting rib 1131 on the arm 113, so as to realize the movement of the paper bin baffle structure inside the paper bin. When the arm 113 is opened, the paper bin baffle structure can be fixed by abutting against the limiting groove through the limiting rib 1131.
