Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and more particularly to a printing terminal device. Background Technology

[0002] Printers on printing terminal equipment are usually embedded inside the printing terminal equipment. When the printer malfunctions or runs out of paper rolls and needs maintenance, the traditional maintenance method is to open the maintenance door of the printing terminal equipment and perform maintenance from inside the printing terminal equipment.

[0003] However, due to the limited space usually available for maintenance doors, and the limited space inside the printing terminal equipment for installing printers, maintenance personnel face limitations in maintaining the printers, making maintenance work inconvenient. Summary of the Invention

[0004] To address the aforementioned problems, embodiments of this application provide a printing terminal device that at least partially solves these problems.

[0005] One or more embodiments of this application provide a printing terminal device, including a device body, a printer assembly, and a rotating door. A receiving groove is provided within the device body; the printer assembly is disposed within the receiving groove, and the printer assembly has a first connection position and a second connection position. The first connection position is rotatably connected to a first inner wall of the receiving groove along a first rotating axis; the rotating door has a first connecting portion and a second connecting portion. The first connecting portion is rotatably connected to the first inner wall along a second rotating axis, and the second connecting portion is rotatably connected to a second connection position of the printer assembly along a third rotating axis. The first, second, and third rotating axes are parallel to each other.

[0006] In one alternative implementation, a limiting hole is provided at the second connection position of the printer assembly. The second connection part includes a connecting rod and a limiting member. The first end of the connecting rod is rotatably connected to the rotating door, and the second end of the connecting rod passes through the limiting hole and is connected to the limiting member. The limiting member is used to keep the connecting rod and the limiting hole in a relatively movable connection.

[0007] In one alternative implementation, a threaded hole is provided at the second end of the connecting rod, and a limiting screw is provided as the limiting element. The second end of the connecting rod passes through the limiting hole, and the connecting rod can move within the limiting hole without coming out by the cooperation of the limiting screw and the threaded hole.

[0008] In one alternative implementation, a locking structure is provided on the rotating door, and a mating part is provided on the second inner wall of the receiving groove. The rotating door is fixed at the opening of the receiving groove by the locking structure engaging with the mating part, so as to lock the printer assembly inside the receiving groove. The rotating door is rotated relative to the receiving groove by the locking structure disengaging from the mating part, so as to remove the printer assembly from the receiving groove.

[0009] In one alternative implementation, the printer assembly includes a bracket, a printer body, and a mounting section. The printer body is detachably connected to the bracket and electrically connected to a circuit board within the device body. The mounting section is detachably connected to the bracket and is used to mount printing paper.

[0010] In one alternative implementation, a limiting part is provided on the bracket, and a stop part is provided on the main body of the device. The stop part is located at the opening of the receiving groove, and the distance that the printer component moves out of the receiving groove is limited by the cooperation between the limiting part and the stop part.

[0011] In one alternative implementation, a paper outlet is provided on the rotating door, which is used to eject paper after the printer body has finished printing.

[0012] In one alternative implementation, a limiting plate is also provided on the side of the rotating door facing the receiving slot. The limiting plate is spaced apart from the rotating door and is used to limit the distance between the printer assembly and the rotating door.

[0013] In one alternative implementation, an indicator light is also provided on the rotating door, spaced apart from the paper output tray, and the indicator light is used to indicate the printing status of the printer components.

[0014] In one alternative implementation, the printer assembly further includes a fixing plate fixedly connected to the first inner wall, and a bracket rotatably connected to the fixing plate.

[0015] A printing terminal device according to an embodiment of this application includes a device body, a printer assembly, and a rotating door. The device body has a receiving slot; the printer assembly is disposed within the receiving slot, and has a first connection position and a second connection position. The first connection position is rotatably connected to the first inner wall of the receiving slot along a first rotating axis. The rotating door has a first connecting portion and a second connecting portion. The first connecting portion is rotatably connected to the first inner wall along a second rotating axis, and the second connecting portion is rotatably connected to the second connection position of the printer assembly along a third rotating axis. The first, second, and third rotating axes are parallel to each other. When maintaining the printer assembly in the printing terminal device of this embodiment, the rotating door can rotate the printer assembly, allowing it to leave the receiving slot of the device body and flip outside the device body. This eliminates the need for maintenance personnel to maintain the printer assembly from inside the printing terminal device, overcoming the limitations of the internal space dimensions of the device body and facilitating operation. Furthermore, when only paper needs to be replaced, contact with the internal circuitry of the device body can be avoided, ensuring operational safety without disconnecting the power to the printing terminal device.

[0029] To provide a clearer understanding of the technical features, objectives, and effects of the embodiments of this application, the specific implementation methods of the embodiments of this application will now be described with reference to the accompanying drawings.

[0030] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0031] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, to make the drawings concise and easy to understand, in some drawings, components with the same structure or function are only schematically shown as one or more, or only one or more are labeled.

[0032] Before describing the printing terminal device of the embodiments of this application, the application scenarios of the printing terminal device will be briefly described to facilitate understanding.

[0033] A printing terminal device can refer to a printing terminal device with printing capabilities. Examples include self-service printing terminal devices in various locations; this embodiment does not limit this. The printer on the printing terminal device is typically embedded inside the device. When the printer malfunctions or runs out of paper, maintenance is traditionally performed by opening the maintenance door and accessing the printer from inside the device. However, the maintenance door and the internal space for the printer are usually limited, restricting maintenance personnel's access and making maintenance difficult. Therefore, this application proposes a printing terminal device that addresses the various problems existing in the prior art.

[0034] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0035] Reference Figures 1 to 7 As shown, the printing terminal device of this embodiment includes a device body 10, a printer assembly 20, and a revolving door 30.

[0036] The device body 10 is provided with a receiving groove 11. Exemplarily, the opening of the receiving groove 11 can be provided on the outer peripheral surface of the device body 10, and this embodiment does not limit this.

[0037] The printer assembly 20 is disposed within the receiving groove 11. The printer assembly 20 has a first connection position and a second connection position. The first connection position is rotatably connected to the first inner wall of the receiving groove 11 along a first rotating shaft L1. Exemplarily, the first inner wall of the receiving groove 11 can be one of the four inner walls connected to the opening of the receiving groove 11; this embodiment does not limit this. The first and second connection positions of the printer assembly 20 can be opposite ends. The first connection position is rotatably connected to the first inner wall of the receiving groove 11 along the first rotating shaft L1. The connection method can be bolt connection, etc., wherein the first rotating shaft L1 is parallel to the edge line corresponding to the opening of the first inner wall of the receiving groove 11, and the third rotating shaft L3 is parallel to the first rotating shaft L1. It should be noted that the first inner wall of the receiving groove 11 can be a fixing plate 24 in the printer assembly 20, with one side of the fixing plate 24 fixedly connected to the edge of the opening of the receiving groove 11 of the device body 10, so that the fixing plate 24 is fixedly located inside the device body 10 to serve as the first inner wall of the receiving groove 11. Alternatively, it can be the device body 10 itself; this embodiment does not limit this.

[0038] The revolving door 30 is provided with a first connecting part and a second connecting part. The first connecting part is rotatably connected to the first inner wall along the second rotating shaft L2, and the second connecting part is rotatably connected to the second connecting position of the printer assembly 20 along the third rotating shaft L3. The first rotating shaft L1, the second rotating shaft L2 and the third rotating shaft L3 are parallel to each other.

[0039] For example, the first connecting part and the second connecting part of the revolving door 30 can be respectively located at opposite ends. The first connecting part is rotatably connected to the first inner wall along the second rotating shaft L2. The connection method can be a latch hinge or the like. The second rotating shaft L2 is parallel to the first rotating shaft L1. The first rotating shaft L1 and the second rotating shaft L2 can be located on the first inner wall, and there is a gap between the first rotating shaft L1 and the second rotating shaft L2. The second connecting position of the printer assembly 20 is rotatably connected to the second connecting part of the revolving door 30 along the third rotating shaft L3. Here, the rotatable connection can refer to the relative displacement between the second connecting position of the printer assembly 20 and the second connecting part of the revolving door 30. This embodiment does not limit this. The third rotating shaft L3 is parallel to the first rotating shaft L1, so that when the revolving door 30 rotates to the outside of the device body 10 along the second rotating shaft L2, the printer assembly 20 can be driven to rotate simultaneously through the second connecting part, thereby moving the printer assembly 20 out of the device body 10.

[0040] The printing terminal device of this embodiment includes a device body 10, a printer assembly 20, and a rotating door 30. A receiving groove 11 is provided inside the device body 10; the printer assembly 20 is disposed within the receiving groove 11, and the printer assembly 20 has a first connection position and a second connection position. The first connection position is rotatably connected to the first inner wall of the receiving groove 11 along a first rotating shaft L1; the rotating door 30 has a first connecting part and a second connecting part. The first connecting part is rotatably connected to the first inner wall along a second rotating shaft L2, and the second connecting part is rotatably connected to the second connection position of the printer assembly 20 along a third rotating shaft L3. The first rotating shaft L1, the second rotating shaft L2, and the third rotating shaft L3 are parallel to each other, and the printer assembly 20 and the rotating door 30 rotate in the same direction. When maintaining the printer assembly 20 in the printing terminal device of this embodiment, the printer assembly 20 can be rotated by the rotating door 30, so that the printer assembly 20 can leave the receiving slot 11 of the device body 10 and flip to the outside of the device body 10. Thus, maintenance personnel do not need to maintain the printer assembly 20 from inside the printing terminal device, and are not limited by the internal space size of the device body 10, making it easier for maintenance personnel to operate. In addition, if only the printing paper is replaced, it is possible to avoid touching the internal circuitry of the device body 10. Therefore, operation safety can be ensured without disconnecting the power to the printing terminal device.

[0041] In one alternative implementation, the printer assembly 20 includes a bracket 21, a printer body 22, and a mounting part 23. The printer body 22 is detachably connected to the bracket 21 and electrically connected to a circuit board within the device body 10. The mounting part 23 is detachably connected to the bracket 21 and is used to mount printing paper.

[0042] For example, refer to Figure 5 The two opposite ends of the bracket 21 can be the first connection position and the second connection position, respectively. The printer body 22 is used to realize the printing function. The connection method between the printer body 22 and the bracket 21 can be bolt connection, welding, etc., which is not limited in this embodiment. The printer body 22 is electrically connected to the circuit board in the device body 10 to supply power to the printer body 22 and send control signals. The mounting part 23 is used to install printing paper, such as a mounting shaft, which can be flexibly set by those skilled in the art according to the specific shape of the printing paper, which is not limited in this embodiment. The mounting part 23 is detachably connected to the bracket 21, such as by bolt connection. If the mounting part 23 is a mounting shaft, a slot can be provided on the bracket 21 to lock the mounting shaft in place. The structure is simple and easier to install and disassemble.

[0043] In one alternative implementation, a limiting hole 211 is provided at the second connection position of the printer assembly 20. The second connection part includes a connecting rod 311 and a limiting member 312. The first end of the connecting rod 311 is rotatably connected to the rotating door 30, and the second end of the connecting rod 311 passes through the limiting hole 211 and is connected to the limiting member 312. The limiting member 312 is used to keep the connecting rod 311 and the limiting hole 211 in a relatively movable connection.

[0044] For example, refer to Figure 3 and Figure 4 The second connecting position of the bracket 21 is provided with a limiting hole 211. The limiting hole 211 can be an elongated hole such as a slotted hole, so that the connecting rod 311 can move in the limiting hole 211 along a first direction. The first direction can be the direction from the first connecting position to the second connecting position, or the direction from the second connecting position to the first connecting position, that is, the connecting rod 311 can reciprocate in the limiting hole 211. The size of the limiting hole 211 can be determined according to the distance between the first rotating shaft L1 and the second rotating shaft L2, which is not limited in this embodiment. There can be two limiting holes 211, respectively provided on both sides of the bracket 21. The connecting rod 311 includes a first end and a second end. The first end is rotatably connected to the revolving door 30, for example, by bolt or hinge. The second end passes through the limiting hole 211 and is connected to the limiting member 312. The limiting member 312 ensures that the connecting rod 311 does not come out when it moves in the limiting hole 211, thus ensuring the connection between the revolving door 30 and the printer assembly 20. This allows the printer assembly 20 to rotate when the revolving door 30 rotates.

[0045] It should be understood that when there is a gap between the first rotating shaft L1 and the second rotating shaft L2, during the process of the rotating door 30 driving the printer assembly 20 to rotate, the connection position of the rotating door 30 and the printer assembly 20 will move relative to each other. This implementation realizes the rotational connection between the rotating door 30 and the printer assembly 20 by moving the connecting rod 311 on the rotating door 30 in the limiting hole 211 on the bracket 21, and the structure is simple.

[0046] In one alternative implementation, the second end of the connecting rod 311 is provided with a threaded hole, and the limiting member 312 is a limiting screw. The second end of the connecting rod 311 passes through the limiting hole 211. Through the cooperation of the limiting screw and the threaded hole, the connecting rod 311 can move within the limiting hole 211 without coming out.

[0047] For example, refer to Figure 4The connecting rod 311 has a threaded hole at its second end, and the limiting member 312 is a limiting screw. The limiting screw rotates through the threaded hole at the second end of the connecting rod 311, restricting the connecting rod 311 within the limiting hole 211. This allows the connecting rod 311 to move within the limiting hole 211 without coming out. The structure is simple and the cost is low.

[0048] In one alternative implementation, a limiting part 212 is provided on the bracket 21, and a stop part 12 is provided on the device body 10. The stop part 12 is located at the opening of the receiving groove 11. The distance that the printer assembly 20 moves out of the receiving groove 11 is limited by the cooperation between the limiting part 212 and the stop part 12.

[0049] For example, refer to Figure 2 and Figure 5 The limiting part 212 can be provided on both sides or one side of the bracket 21. The limiting part 212 can be a limiting sheet metal. The stop part 12 is provided on the device body 10 at the opening of the receiving groove 11. For example, it can be a part of the surface of the device body 10 where the receiving groove 11 is located extending towards the opening of the receiving groove 11, that is, the size of the receiving groove 11 near the opening is smaller than the size of the receiving groove 11 inside. The stop part 12 can be fixedly connected to the device body 10, or it can be integrally formed with the surface of the device body 10. This embodiment does not limit this. When the rotating door 30 is opened, the rotating door 30 drives the printer assembly 20 to rotate outward of the device body 10 until the limiting part 212 on the bracket 21 abuts against the stop part 12 on the device body 10, restricting the movement of the printer assembly 20, so that the rotating door 30 and the printer assembly 20 stop rotating and reach the limit position, that is, the maximum distance that the printer assembly 20 moves out of the receiving groove 11. If the first inner wall is the inner wall of the receiving groove 11 that is close to the ground, then the rotation direction of the rotating door 30 and the printer assembly 20 is towards the ground. When the limiting part 212 on the bracket 21 abuts against the stop part 12 on the main body 10 of the equipment, it can overcome the gravity of the rotating door 30 and the printer assembly 20, so that the rotating door 30 and the printer assembly 20 can remain stationary at the extreme position without the need to set other limiting structures, thus facilitating operation by maintenance personnel.

[0050] In one alternative implementation, the printer assembly 20 further includes a fixing plate 24, which is fixedly connected to the first inner wall, and the bracket 21 is rotatably connected to the fixing plate 24.

[0051] For example, refer to Figure 5The printer assembly 20 also includes a fixing plate 24, which is fixedly connected to the first inner wall. The connection method can be bolted or similar. The first connection position of the bracket 21 is rotatably connected to the fixing plate 24, and the connection method can be hinged or similar. The fixing plate 24 allows the entire printer assembly 20 to be disassembled and installed from the main body 10, making the overall structure of the printer assembly 20 more compact.

[0052] In one alternative implementation, a locking structure 32 is provided on the rotating door 30, and a mating part is provided on the second inner wall of the receiving groove 11. The rotating door 30 is fixed at the opening of the receiving groove 11 by the locking structure 32 engaging with the mating part, so as to lock the printer assembly 20 inside the receiving groove 11. The rotating door 30 is rotated relative to the receiving groove 11 by the locking structure 32 disengaging from the mating part, so as to remove the printer assembly 20 from the receiving groove 11.

[0053] For example, refer to Figure 6 The locking structure 32 can be a resilient pin, and the mating part can be a slot. The mating part is disposed on the second inner wall of the receiving groove 11. The second inner wall can be opposite to or adjacent to the first inner wall; this embodiment does not impose any restrictions on this. The mating part is located on the second inner wall near the opening of the receiving groove 11, so that the rotating door 30 can engage with the locking structure 32 after being closed. This fixes the rotating door 30 at the opening of the receiving groove 11. When the locking structure 32 engages with the mating part, fixing the rotating door 30 at the opening of the receiving groove 11, the rotating door 30 seals the printer assembly 20 inside the receiving groove 11. By disengaging the locking structure 32 from the mating part, the rotating door 30 can be rotated relative to the receiving groove 11, thereby rotating the printer assembly 20 to remove it from the receiving groove 11.

[0054] In this implementation, by setting a locking structure 32 on the rotating door 30 and a mating part on the second inner wall of the receiving groove 11, the rotating door 30 can be closed and opened. Thus, when the printer assembly 20 does not need maintenance, it can be sealed inside the receiving groove 11, preventing the printer assembly 20 from being exposed to the outside for a long time and easily damaged, reducing the space occupied by the printing terminal equipment, and improving the aesthetics. When the printer assembly 20 needs maintenance, it can be removed from the receiving groove 11 for easy operation by maintenance personnel.

[0055] In one alternative implementation, a paper outlet 33 is provided on the rotating door 30, which is used to output paper after the printer body 22 has finished printing.

[0056] For example, refer to Figure 6 and Figure 7The rotating door 30 is also equipped with a paper outlet 33, through which the printed paper from the printer body 22 can be discharged. The position of the paper outlet 33 on the rotating door 30 can be determined according to the position of the printer body 22 on the bracket 21, so as to ensure that when the rotating door 30 is closed, the paper output position of the printer body 22 after printing can be aligned with the paper outlet 33 on the rotating door 30 for easy paper output.

[0057] In one alternative implementation, an indicator light 35 is also provided on the rotating door 30, and the indicator light 35 is spaced apart from the paper output outlet 33. The indicator light 35 is used to indicate the printing status of the printer assembly 20.

[0058] For example, refer to Figure 6 and Figure 7 The revolving door 30 is also equipped with an indicator light 35, which is electrically connected to the circuit board inside the main body 10 of the device to supply power to the indicator light 35 and send control signals. The indicator light 35 and the paper output port 33 can be set at intervals, and the interval size is not limited. The indicator light 35 can indicate the printing status of the printer component 20, such as printing, printing failure, printing completed, etc.; and the indicator light 35 can also indicate whether there is a lack of printing paper, etc. This embodiment does not limit this.

[0059] In one alternative implementation, a limiting plate 34 is also provided on the side of the rotating door 30 facing the receiving groove 11. The limiting plate 34 is spaced apart from the rotating door 30 and is used to limit the distance between the printer assembly 20 and the rotating door 30.

[0060] For example, refer to Figure 6 and Figure 7 A limiting plate 34 is also provided on the side of the rotating door 30 facing the receiving groove 11. The limiting plate 34 is spaced apart from the rotating door 30, and its position does not overlap with the paper output outlet 33, meaning the limiting plate 34 will not obstruct the paper output outlet 33. When the first inner wall is the inner wall of the receiving groove 11 closest to the ground, during the rotation to the limit position, the printer assembly 20 will be pressed against the rotating door 30 under the action of gravity. The limiting plate 34 on the inner side of the rotating door 30 can support the printer assembly 20, limiting the distance between the printer assembly 20 and the rotating door 30, thereby preventing the printer assembly 20 from pressing against the indicator light 35 and the paper output outlet 33 on the rotating door 30. Preferably, the limiting plate 34 can be positioned between the indicator light 35 and the paper output outlet 33 to ensure that both the indicator light 35 and the paper output outlet 33 can maintain a safe distance from the printer assembly 20.

[0061] In the embodiments of this application, reference is made to Figure 1 and Figure 2Taking the inner wall of the receiving groove 11 near the ground as an example, the movement process of the rotating door 30 driving the printer assembly 20 is explained as follows: When the printer assembly 20 needs maintenance, the maintenance personnel open the elastic locking mechanism of the rotating door 30, pull the rotating door 30 to rotate towards the ground, and drive the connecting rod 311 to move. At the same time, the connecting rod 311 slides away from the main body 10 in the limiting hole 211 on the bracket 21, while pulling the bracket 21 to rotate. At this time, the printer assembly 20 and the rotating door 30 are in a state of linkage rotation. Continuing to pull the rotating door 30 to rotate, when the limiting part 212 on the bracket 21 collides with the stop part 12 of the main body 10, the rotation movement stops. At this time, the printer assembly 20 rotates to the limit position, and both the rotating door 30 and the printer assembly 20 are stationary, making it convenient for maintenance personnel to maintain the printer assembly 20.

[0062] After maintenance personnel complete the maintenance of printer assembly 20, they pull the rotating door 30 to close it by flipping it away from the ground. The limiting plate 34 on the inner side of the rotating door 30 pushes the printer assembly 20, causing it to flip synchronously with the rotating door 30. Continuing to pull the rotating door 30 to a certain angle, the printer assembly 20, under the influence of gravity, will automatically flip towards the main body 10 of the device. The printer assembly 20 flips back onto the fixed plate 24, where the locking structure 32 engages with the mating part to close the rotating door 30.
