DETAILED DESCRIPTION

[0037] The invention discloses a paper bin cover opening and closing control component and a printing device, which are used to solve the technical problem that the existing paper bin cover is easily affected by its own gravity when in an open state and automatically tilts forward and falls, thereby causing inconvenience to the user.

[0038] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 9 , a paper bin cover opening and closing control assembly provided by an embodiment of the present invention comprises a paper bin cover 1 and a paper bin body 2, wherein the paper bin cover 1 is hinged to the paper bin body 2, and the paper bin cover 1 is driven to rotate relative to the paper bin body 2 to switch between an open state of opening the paper bin body 2 and a closed state of closing the paper bin body 2;

[0040] The outer side of the paper bin cover 1 is provided with a linear slide groove 3, and a guide column 4 is elastically connected to the linear slide groove 3. The guide column 4 can move along the linear slide groove 3 under the action of elastic force. An arcuate slide groove 6 is provided on the inner side wall of the paper bin cover 1 corresponding to the linear slide groove 3, and the end of the guide column 4 is slidably connected to the arcuate slide groove 6;

[0041] The arc-shaped slide groove 6 has a first position a, and a limiting structure used in conjunction with the guide column 4 is provided at the first position a. The limiting structure is used to limit the guide column 4 to the first position a so that the paper bin cover 1 is maintained in an open state.

[0042] In the paper bin cover opening and closing control assembly of this embodiment, Figure 1 and Figure 2As shown, when the user turns the paper bin cover 1 to open it, the guide post 4 can move synchronously in the arc chute 6 and the linear chute 3, and finally stay in the first position a of the arc chute 6. At this time, due to the existence of the limiting structure, the limiting structure limits the guide post 4 in the first position a, so that the paper bin cover 1 is always maintained in the open state. Through the above design, after the user opens the paper bin cover 1, the paper bin cover 1 can always remain in the open state, so that the user can easily perform operations such as changing the paper roll, and effectively improve the user's experience.

[0043] Furthermore, if Figure 4 As shown, in one specific implementation of this embodiment, the above-mentioned limiting structure is specifically an arc-shaped protrusion 7 protruding from the inner groove wall of the arc-shaped sliding groove 6;

[0044] With such a design, when the paper bin cover 1 is driven to rotate relative to the paper bin body 2 to enter the open state, the guide post 4 passes over the arc-shaped protrusion 7 and is restricted by the arc-shaped protrusion 7 to the first position a.

[0045] In addition, it should be noted that when the user needs to flip the paper bin cover 1 downward to cover the paper bin body 2, the guide column 4 needs to pass over the above-mentioned arc-shaped protrusion 7. At this time, the user needs to apply a large pressure to the paper bin cover 1 to ensure that the paper bin cover 1 is flipped downward; relatively, when the user does not apply a large pressure to the paper bin cover 1, the above-mentioned guide column 4 will not pass over the arc-shaped protrusion 7, and the gravity of the paper bin cover 1 is also very small and can be ignored. Therefore, through the above design, the paper bin cover 1 can be maintained in an open state, thereby effectively preventing the paper bin cover 1 from tilting forward and falling naturally.

[0046] It should be further explained that the surface where the guide column 4 contacts the arc-shaped protrusion 7 is an arc-shaped surface, so that the guide column 4 can pass over the arc-shaped protrusion 7 when subjected to force.

[0047] Furthermore, in one of the specific embodiments, an arc-shaped groove 8 is provided at a position where the inner groove wall of the arc-shaped groove 6 is opposite to the arc-shaped protrusion 7, thereby providing sufficient space for the guide post 4 to pass over the arc-shaped protrusion 7, thereby enabling the guide post 4 to conveniently pass over the arc-shaped protrusion 7.

[0048] In addition, in another specific embodiment, the guide post 4 can also be made of elastic material, such as rubber, silicone, etc. Through the above design, when the guide post 4 passes over the arc-shaped protrusion 7, it can be compressed to produce a certain deformation, thereby facilitating passing over the arc-shaped protrusion 7.

[0049] Furthermore, if Figure 3 As shown, in this embodiment, the guide column 4 is connected to an elastic member 5 , and one end of the elastic member 5 away from the guide column 4 is connected to the groove wall of the linear slide groove 3 .

[0050] Specifically, the elastic member 5 is a tension spring extending along the linear slide slot 3 , a first end of the tension spring being connected to the guide post 4 , and a second end of the tension spring being connected to the slot wall of the linear slide slot 3 .

[0051] Furthermore, if Figure 4 As shown, the arc-shaped slide groove 6 in this embodiment is similar to a U-shaped structure, which specifically comprises a first section 601, a second section 603 and a curved section 602 connecting the first section 601 and the second section 603;

[0052] The first section 601 and the second section 603 are both arranged to be inclined downward toward the inside of the paper bin body 2 , the first section 601 is located above the second section 603 , and the first position a is located at a position where the first section 601 is away from the curved section 602 .

[0053] It should be noted that when the paper bin cover 1 rotates relative to the paper bin body 2 and enters the open state from the closed state, the guide post 4 passes through the curved section 602 from the second section 603 and then enters the first section 601, and is finally limited to the first position a by the limiting structure.

[0054] Furthermore, if Figure 5 and Figure 6 As shown, the arc-shaped slide groove 6 in this embodiment has a second position b, and the second position b is located in the bending section 602;

[0055] When the paper bin cover 1 is driven to rotate relative to the paper bin body 2 so that the guide post 4 enters the second position b, the elastic force of the elastic member 5 is at its maximum value, and the elastic member 5 tends to drive the guide post 4 to enter the first section 601 or the second section 603, thereby tending to cause the paper bin cover 1 to enter an open state or a closed state.

[0056] It should be noted that in the above design, when the guide column 4 is in the second position b, the elastic member 5, i.e., the tension spring, is stretched to the maximum extent and its elastic force is at the maximum value, and the tension spring tends to drive the guide column 4 to move in the direction of the first section 601 or the second section 603.

[0057] Therefore, through the above design, in the process of switching the paper bin cover 1 from a closed state to an open state, when the guide post 4 passes through the second position b, the tension spring will drive the guide post 4 to enter the first position a of the first section 601, so that the paper bin cover 1 is automatically opened, thereby playing a power assisting role; in addition, it can be simply understood that in the process of switching the paper bin cover 1 from an open state to a closed state, when the guide post 4 passes through the second position b, the tension spring will drive the guide post 4 to enter the second section 603 to enter the third position c, so that the paper bin cover 1 is automatically closed.

[0058] It can be seen from the above process that the elastic member 5 can help the paper bin cover 1 to open or close, making it more convenient for users to use.

[0059] Furthermore, if Figure 7 and Figure 8 As shown, the arc-shaped slide groove 6 has a third position c, and the third position c is located at a position where the second section 603 is away from the curved section 602;

[0060] When the paper bin cover 1 is driven to rotate relative to the paper bin body 2 so that the guide post 4 enters the third position c, the paper bin cover 1 covers the paper bin body 2 to enter a closed state.

[0061] It should be noted that, through the above design, when the guide post 4 enters the third position c, the elastic member 5, such as a tension spring, tends to move the guide post 4 toward the second section 603, thereby tending to make the paper bin cover 1 firmly cover the paper bin body 2.

[0062] Furthermore, if Fig. 9 As shown, the guide column 4 in this embodiment specifically includes a main body portion 402 slidably connected to the linear slide groove 3 and a column portion 401 slidably connected to the arcuate slide groove 6;

[0063] The main body 402 is connected to the column portion 401 , and the main body 402 is connected to the elastic member 5 .

[0064] It should be noted that, in order to ensure the stability of the structure, the main body 402 and the column 401 are an integrally formed structure.

[0065] Furthermore, in the present embodiment, the paper bin cover 1 is connected with an axis, and the paper bin body 2 is provided with an axis hole, and the axis is rotatably connected in the axis hole so that the paper bin cover 1 is hinged to the paper bin body 2.

[0066] In one specific embodiment, when the paper bin cover 1 rotates clockwise relative to the paper bin body 2, the paper bin cover 1 switches from a closed state to an open state, and when the paper bin cover 1 rotates counterclockwise relative to the paper bin body 2, the paper bin cover 1 switches from an open state to a closed state.

[0067] See also Figures 1 to 9 A printing device provided by an embodiment of the present invention includes the above-mentioned paper bin cover opening and closing control component.

[0068] Specifically, the above-mentioned printing device may be a POS machine or an office printer.

[0069] It should be noted that, through the above design, when the user turns the paper bin cover 1 to open it, the guide post 4 can move synchronously in the arc chute 6 and the linear chute 3, and finally stay in the first position a of the arc chute 6. At this time, due to the existence of the limiting structure, the limiting structure limits the guide post 4 in the first position a, so that the paper bin cover 1 is always maintained in the open state. Through the above design, after the user opens the paper bin cover 1, the paper bin cover 1 can always remain in the open state, so that the user can easily perform operations such as changing the paper roll, and effectively improve the user's experience.

[0070] The above is a detailed introduction to a paper bin cover opening and closing control component and a printing device provided by the present invention. For a person skilled in the art, according to the idea of ​​the embodiments of the present invention, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
