Description

Technical Field

[0001] This utility model relates to the field of document printers, and in particular to a document printer that is easy to operate. Background Technology

[0002] The document printer is suitable for departments such as human resources and social security, housing and construction, civil affairs, disabled persons' federation, and the military. It can solve the printing output of documents with one code per document, image collection, and electronic seals, eliminating the outdated manual photo pasting and stamping process, saving issuance time, and enabling long-term preservation of documents.

[0003] Among them, the prior art CN209794885U discloses a printing platform for a certificate printer, which can ensure that the top surface of the left and right sides or multiple sides of the certificate is consistent with the distance between the print head and the print head, so that the print head can print on the entire page of the certificate, resulting in good printing effect.

[0004] However, the control screen of traditional document printers is placed horizontally, which is very inconvenient for some people who are shorter. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a convenient document printer.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A user-friendly document printer includes a lower housing and an upper panel. The panel has a scanning area and an operation area, and the operation area is equipped with a control screen assembly.

[0008] The lower part of the control screen assembly is connected to a rotating mechanism. There are two sets of rotating mechanisms located at the front and rear ends of the control screen respectively. Both rotating mechanisms are located below the control screen assembly and connected to the left end of the control screen assembly.

[0009] The rotating mechanism is located inside the housing and includes a rotating arm 1, a rotating arm 2, and a fixed arm. The upper end of the rotating arm 1 is connected to the bottom of the panel and can rotate relative to the panel. The lower end of the rotating arm 1 is hinged to the rotating arm 2, and the other end of the rotating arm 2 is hinged to the fixed arm. The control panel assembly is fixedly connected to the fixed arm. In the initial state, the rotating arm 1 and the rotating arm 2 form a V-shaped structure, and the control panel assembly is placed horizontally in the slot opened on the panel. The connecting and rotating positions of the rotating arm 1, the rotating arm 2, and the fixed arm are all equipped with damping structures.

[0010] Preferably, the fixed arm includes a horizontal part in the middle, a connecting part on the left side of the horizontal part, and a vertical part on the right side of the horizontal part. The fixed part is an integrally formed structure. The connecting part and the horizontal part form a certain angle. The connecting part extends to the lower left of the horizontal part. A connecting hole is provided on the connecting part. The rotating arm and the connecting hole are connected by a connecting shaft. The rotating arm and the connecting hole can rotate around the connecting shaft.

[0011] Preferably, the center of the panel is provided with a mounting slot for installing the control screen assembly. The left side of the mounting slot is the barcode scanning area. When the control screen assembly is placed horizontally, there is a clearance between the left end of the control screen and the right side panel of the barcode scanning area. An opening is provided on the lower side of the right side panel of the barcode scanning area, through which the fixing arm passes. The upper end of the opening is a certain clearance from the upper end of the fixing arm.

[0012] Preferably, the lower end of the first rotating arm is the first connecting part, and the lower end of the second rotating arm is the second connecting part. The first rotating arm is provided with an annular groove, and the second rotating arm is provided with a guide column installed on its inner side. The guide column is installed in the annular groove. A bolt hole for installing a connecting bolt is provided at the middle position of the first connecting part and the second connecting part. The bolt is inserted into the bolt hole to fix the first connecting part and the second connecting part.

[0013] Preferably, the annular groove is composed of groove segment one and groove segment two. The width of both groove segment one and groove segment two gradually decreases in a counterclockwise direction. The large diameter of groove segment one connects to the small diameter of groove segment two, and the small diameter of groove segment one connects to the large diameter of groove segment two.

[0014] Preferably, the first and second sections of the channel are the same size, and the guide column includes a limiting column and a middle fixing column. The cross-sectional diameter of the fixing column is smaller than the maximum width of the first and second sections of the channel, but larger than the minimum width of the first and second sections of the channel.

[0015] As a preferred option, the fixing post is made of rubber. As the control panel assembly is lifted, the V-shaped opening gradually increases, and the fixing post moves towards the smaller diameter sections of the first and second slots.

[0016] Compared with existing technologies, this solution has the following advantages: the display screen of the document printer can be flipped, and the damping structure designed can ensure that it is suspended in the desired position. At the same time, the playback is faster without damping. The entire rotating mechanism is located inside, resulting in a neat appearance. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] A convenient document printer includes a lower housing 1 and an upper panel 2. The panel 2 is provided with a barcode scanning area 3 and an operation area. The operation area is equipped with a control screen assembly 4.

[0027] The lower part of the control screen assembly 4 is connected to a rotating mechanism 5. There are two sets of rotating mechanisms 5 located at the front and rear ends of the control screen respectively. Both rotating mechanisms 5 are located below the control screen assembly 4 and connected to the left end of the control screen assembly 4.

[0028] The rotating mechanism 5 is located inside the housing 1 and includes a first rotating arm 6, a second rotating arm 7, and a fixed arm. The upper end of the first rotating arm 6 is connected to the bottom of the panel 2 and can rotate relative to the panel 2. The lower end of the first rotating arm 6 is hinged to the second rotating arm 7, and the other end of the second rotating arm 7 is hinged to the fixed arm. The control screen assembly 4 is fixedly connected to the fixed arm. In the initial state, the first rotating arm 6 and the second rotating arm 7 form a V-shaped structure, and the control screen assembly 4 is placed horizontally in the slot opened on the panel 2. Damping structures are provided at the connection and rotation positions of the first rotating arm 6, the second rotating arm 7, and the fixed arm. The entire mechanism can realize the folding of the screen, making it more convenient for users to use. At the same time, the design of the damping structure can ensure that the screen is in a stable position after folding.

[0029] In this design, the fixed arm includes a horizontal section 8 in the middle, a connecting section 9 on the left side of the horizontal section 8, and a vertical section 10 on the right side of the horizontal section 8. The fixed section is a one-piece molded structure. The connecting section 9 and the horizontal section 8 form a certain angle. The connecting section 9 extends to the lower left of the horizontal section 8 and has a connecting hole 11. The rotating arm 7 and the connecting hole 11 are connected by a connecting shaft. The rotating arm 7 and the connecting hole 11 can rotate around the connecting shaft. This structural design of the fixed arm can avoid interference between the operation screen assembly and the panel 2 and other structures, and the rotation is more stable.

[0030] In this design, a mounting slot for mounting the control panel assembly 4 is provided in the middle of the panel 2. This structural design ensures that the upper surface of the control panel assembly 4 is flush with the upper surface of the panel 2.

[0031] In this design, the left side of the mounting slot is the scanning area 3. When the control screen assembly 4 is placed horizontally, there is a clearance 12 between the left end of the control screen and the right side plate of the scanning area 3. An opening 13 is provided on the lower side of the right side plate of the scanning area 3, through which the fixing arm passes. The upper end face of the opening 13 is a certain clearance from the upper end face of the fixing arm. This structural design ensures the rotation of the control screen assembly and avoids jamming. Moreover, the opening 13 structure is hidden in the lower part, making the appearance more aesthetically pleasing.

[0032] In this design, the lower end of the first rotating arm 6 is the first connecting part 14, and the lower end of the second rotating arm 7 is the second connecting part 15. An annular groove 16 is provided inside the first rotating arm 6, and a guide column 17 is installed inside the second rotating arm 7. The guide column 17 is installed within the annular groove 16. A bolt hole for installing connecting bolts is provided at the middle position between the first connecting part 14 and the second connecting part 15. The bolts are inserted into the bolt holes to fix the first connecting part 14 and the second connecting part 15. The annular groove 16 consists of a first groove segment 18 and a second groove segment 19. The widths of both the first groove segment 18 and the second groove segment 19 gradually decrease counterclockwise. The larger diameter of the first groove segment 18 connects to the smaller diameter of the second groove segment 19, and vice versa. This groove-shaped structure design ensures that the control screen assembly 4 has damping when it flips to the user side, allowing it to hover in the desired position. On the other hand, as the groove becomes larger, the damping disappears, allowing the control screen assembly 4 to be easily placed horizontally.

[0033] In this design, slot 18 and slot 219 are the same size. The guide post 17 includes a limiting post 20 and a middle fixing post 21. The cross-sectional diameter of the fixing post 21 is smaller than the maximum width of slot 18 and slot 219, but larger than the minimum width of slot 18 and slot 219. The fixing post 21 is made of rubber. As the control panel assembly 4 is lifted, the V-shaped opening gradually increases, and the fixing post 21 moves towards the smaller diameter portion of slot 18 and slot 219.

[0034] In use, the user flips the control screen assembly 4, the fixed part rotates downward, the included angle between the first rotating arm 6 and the second rotating arm 7 widens, the guide column 17 rotates towards the narrow diameter of the annular groove 16, the guide column 17 and the narrow part of the annular groove 16 are squeezed, thereby generating damping, after the rotation stops, the first rotating arm 6 and the second rotating arm 7 will not return to their original position under the action of damping.

[0035] The connection between the fixed arm and the rotating arm 7 is also achieved using the method of rotating arm 6 and rotating arm 7, which is not shown in the figure.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that the fixed arm and the rotating arm 7 are locked together by bolts and nuts, and their relative positions are controlled by friction (not shown in the figure).

[0038] Example 3

[0039] The difference between this embodiment and embodiment 1 is that the connecting part 14 and the connecting part 2 15 are connected by bolts and nuts.
