[0010] As a further improvement of the present technical solution, the top surface of the external plate includes a connecting surface and a supporting surface, the supporting surface is horizontal, the connecting surface is an arc-shaped surface, and the connecting surface is tangent to the extended surface of the top surface of the guide head.

[0011] As a further improvement of the present technical solution, the bottom surface of the turning groove is smoothly connected to the top surface of the paper board, and the turning groove is an arc-shaped groove as a whole.

[0012] As a further improvement of the present technical solution, the chute is arranged at an angle.

[0013] As a further improvement of the present technical solution, an extrusion assembly is provided at the top of the paperboard output, and the extrusion assembly includes a rotating plate and an adapter plate. Two adapter plates are provided, which are respectively arranged on the two side walls of the top of the rotating plate and are rotatably connected to the rotating plate. The bottom end of the rotating plate is rotatably connected to a squeezing roller, wherein:

[0014] A second motor is provided on one side of the rotating plate that is rotatably connected to the adapter plate, and a first motor is provided on one side of the squeezing roller that is rotatably connected to the rotating plate.

[0015] As a further improvement of the present technical solution, a transfer groove is symmetrically opened at the bottom of the rotating plate, an auxiliary plate is rotatably connected in the transfer groove, an auxiliary roller is rotatably connected between the two auxiliary plates, a third motor is arranged on the side where the auxiliary roller is connected to the auxiliary plate, and a second electric push rod is arranged between the auxiliary plate and the bottom wall of the rotating plate, one end of the second electric push rod is rotatably connected to the bottom wall of the rotating plate, and the other end is rotatably connected to the outer wall of the auxiliary plate.

[0016] As a further improvement of the present technical solution, it includes an authentication query unit, an external monitoring access unit, a query environment identification unit, a blockchain storage unit, and a control unit; the authentication query unit is used to authenticate the identity of the inquiring person, retrieve the corporate credit information of the authenticated person after successful authentication, and form a credit report and store it in the blockchain storage unit for query; the external monitoring access unit is used to access the monitoring of the location where the query device is located and send it to the query environment identification unit; the query environment identification unit is used to identify the environment around the query device within the monitoring.

[0017] A second object of the present invention is to provide a query method for the above-mentioned blockchain-based enterprise credit report query device, comprising the following method steps:

[0018] S1. The authentication query unit authenticates the identity of the querying person;

[0019] S2. After successful authentication, the authenticated enterprise credit information is retrieved and a credit report is generated and stored in the blockchain storage unit;

[0020] S3, the external monitoring access unit accesses the monitoring of the location where the query device is located;

[0021] S4. The query environment identification unit identifies the environment surrounding the query device within the monitoring area.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the blockchain-based corporate credit report query method, device, and system, a first electric push rod pushes the telescopic plate to slide in the slide groove, thereby realizing switching between different working modes. The main function is to make the credit report form enter the turning groove along the output cardboard and fold inward through its limit. In this way, the printed surface of the credit report form will not be flattened. In this state, the printed content cannot be seen, thereby achieving privacy protection.

[0024] 2. In the blockchain-based corporate credit report query method, device and system, the credit report form is squeezed by the squeezing roller and the steering groove. After being squeezed, the credit report form will bend and form a roll structure. In this way, the printed content is all on the inner side of the roll-shaped credit report form and cannot be seen. It can only be seen when the credit report form is flattened, thereby achieving privacy protection. Moreover, the credit report form in a roll structure directly stays on the top of the rotating plate, which is also convenient for taking. Although there is a certain damage to the credit report form, considering that the credit report form is generally rolled into a roll structure for easy storage after taking it, this also saves the step of manual winding in the later stage.

[0025] 3. In the blockchain-based corporate credit report query method, device and system, the top surface of the external plate includes a connecting surface and a supporting surface. The supporting surface is horizontal to support the credit report for easy removal, while the connecting surface is an arc-shaped surface and is tangent to the extended surface of the top surface of the guide head to ensure smoothness between the top surface of the paperboard, the top surface of the guide head and the connecting surface, thereby avoiding paper jams during the transmission of the credit report.

[0026] 4. In the blockchain-based corporate credit report query method, device and system, the external monitoring access unit accesses the monitoring of the location of the query device, and then the query environment identification unit identifies the environment around the query device in the monitoring, and then cooperates with the control unit to realize automatic conversion of the privacy mode.

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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 efforts are within the scope of protection of the present invention.

[0050] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0051] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature identified as "first," "second," or "third" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0052] See also Figure 1 As shown, one of the purposes of this embodiment is to provide a blockchain-based enterprise credit report inquiry device, including a printer body 100, with a printing outlet 110 set on the top of the printer body 100. After the enterprise credit report inquiry is completed, the credit report to be printed is printed by the printer body 100 and delivered from the printing outlet 110. However, considering that there will be many people queuing behind the device during the inquiry, although a one-meter line is set, it is not ruled out that someone will cross the one-meter line. If this happens, directly printing out the credit report will easily cause privacy leakage. For this purpose, please refer to Figure 2As shown, a multi-mode paper output assembly 200 is specifically disclosed. The multi-mode paper output assembly 200 is disposed in the print outlet 110 and includes a paper output board 210 and a multi-mode conversion member 220. The bottom wall of the paper output board 210 is connected to the inner wall of the print outlet 110, and the rear end of the paper output board 210 extends to the paper output position in the print outlet 110. Its main purpose is to carry the paper (i.e., the credit report) delivered from the print outlet 110. The multi-mode conversion member 220 is disposed at the front end of the paper output board 210, wherein:

[0053] See also Figure 3 As shown, the multi-mode conversion member 220 includes a telescopic plate 221 and a first electric push rod 222. The telescopic plate 221 is slidably connected to the paper board 210. A slide groove is provided on the sliding path of the print outlet 110 corresponding to the telescopic plate 221. The first electric push rod 222 is arranged in the slide groove, and the piston rod provided at its telescopic end is fixedly connected to the telescopic plate 221. Its main purpose is to push the telescopic plate 221 to slide in the slide groove, thereby realizing switching between different working modes, specifically including privacy mode and straight-out mode. In order to realize switching between these two modes, a turning groove 2211 is provided on the side of the telescopic plate 221 close to the paper board 210. After opening, a guide head 2212 is formed at the top of the telescopic plate 221.

[0054] The principle of the specific working method is illustrated by examples 1 and 2: Example 1

[0055] This embodiment discloses the direct output mode, please refer to Figure 4 As shown in the figure, a is the paper output direction of the credit report. In this embodiment, the telescopic plate 221 is stored in the slide groove, and the top surface of the guide head 2212 coincides with the extended surface of the top surface of the paper output paper board 210, thereby ensuring that the credit report can be smoothly delivered. In this embodiment, there is no need to apply pressure to the credit report, which causes less damage to it. However, it does not have the effect of privacy protection and is more suitable for use when individuals print alone or in a safer environment.

[0056] In addition, in order to prevent the distance of the paperboard 210 from being too short to support the credit report form, the credit report form is easy to fall off and it is inconvenient to take the credit report form, for this purpose, please refer to Figure 5As shown, an external plate 211 is provided on the outside of the paperboard 210, and a distance is left between the external plate 211 and the paperboard 210, the main purpose of which is to provide space for the telescopic plate 221 to slide, to ensure that the telescopic plate 221 can slide out normally, and the top surface of the external plate 211 includes a connecting surface and a supporting surface, the supporting surface is in a horizontal state to support the credit report for easy taking, and the connecting surface is an arc surface, and is tangent to the extended surface of the top surface of the guide head 2212, to ensure the smoothness between the top surface of the paperboard 210, the top surface of the guide head 2212 and the connecting surface, to avoid paper jams during the transmission of the credit report. Example 2

[0057] This embodiment discloses the privacy mode, please refer to Figure 6 As shown in the figure, a is the paper output direction of the credit report, and b is the limiting direction of the steering groove 2211. First, the first electric push rod 222 works, and its piston rod pushes the telescopic plate 221 to slide out along the slide groove. The telescopic plate 221 in Example 1 is stored in the slide groove as the reference state. When the telescopic plate 221 slides out, the bottom surface of the steering groove 2211 is smoothly connected to the top surface of the paper output paper 210. The steering groove 2211 is an arc-shaped groove as a whole. In order to facilitate the entry of the credit report, the steering groove 2211 needs to be inclined. If the telescopic plate 221 is stored in the slide groove in Example 1, the bottom surface of the steering groove 2211 is smoothly connected to the top surface of the paper output paper 210. When the retractable plate 221 slides out vertically, the width range of the turning slot 2211 needs to be larger. For this purpose, the sliding slot is opened at an angle, so that the retractable plate 221 itself tilts outward after sliding out, so that the width range of the turning slot 2211 is adaptably reduced, thereby reducing the space occupied by the retractable plate 221. Then, the credit report form enters the turning slot 2211 along the paper board 210 and is folded inward through its limit. In this way, the printed surface of the credit report form will not be flattened out. In this state, the printed content cannot be seen, thereby achieving privacy protection. Example 3

[0058] Considering that the credit report is likely to fall into the printing outlet 110 after being limited, it is inconvenient to take it out. Figure 7 and Figure 8 As shown, a squeezing assembly 230 is provided on the top of the paperboard 210. The squeezing assembly 230 includes a rotating plate 231 and an adapter plate 232. Two adapter plates 232 are provided, which are respectively provided on the two side walls of the top of the rotating plate 231 and are rotatably connected to the rotating plate 231. The bottom end of the rotating plate 231 is rotatably connected to a squeezing roller 2311, wherein:

[0059] A second motor 2321 is provided on the side where the rotating plate 231 is rotatably connected to the adapter plate 232, and its main purpose is to drive the rotating plate 231 to rotate. A first motor 2312 is provided on the side where the squeezing roller 2311 is rotatably connected to the rotating plate 231, and its main purpose is to drive the squeezing roller 2311 to rotate.

[0060] Working principle:

[0061] See also Figure 9 As shown in the figure, c is the extrusion direction of the extrusion roller 2311. When the credit report form enters the steering groove 2211, the first motor 2312 works to drive the extrusion roller 2311 to rotate, and the credit report form is squeezed by the extrusion roller 2311 and the steering groove 2211. After being squeezed, the credit report form will bend and form a roll structure. In this way, the printed content is all on the inner side of the roll-shaped credit report form and cannot be seen. It can only be seen when the credit report form is flattened, thereby achieving privacy protection. Moreover, the credit report form in a roll structure directly stays on the top of the rotating plate 231, which is also convenient for taking. Although there is some damage to the credit report form, considering that the credit report form is generally wound into a roll structure for easy storage after taking it, this also saves the step of manual winding in the later stage.

[0062] It is worth noting that the radius of the extrusion roller 2311 is slightly smaller than the radius of the inner arc surface part of the guide head 2212, and the first motor 2312 drives the extrusion roller 2311 to rotate to the center of the inner arc surface part of the guide head 2212, thereby ensuring that a circular arc-shaped extrusion groove is formed between the extrusion roller 2311 and the turning groove 2211, which is more convenient for the formation of the credit report form. In addition, the rotation speed of the extrusion roller 2311 is synchronized with the paper output speed of the credit report form.

[0063] Also, see Figure 10 As shown, a top plate 2313 is provided on the top of the rotating plate 231, and the formed credit report falls directly on the top plate 2313, preventing the credit report from being sucked into the squeezing roller 2311 again and causing damage. Example 4

[0064] See also Figure 11 As shown in the figure, d is the driving direction of the second motor 2321. This embodiment discloses another working mode of the squeezing roller 2311, which is used in combination with the direct-dispensing mode. Taking Example 3 as the initial state, the second motor 2321 first drives the rotating plate 231 to rotate, causing it to drive the squeezing roller 2311 into the print outlet 110. Then, the telescopic plate 221 is driven by the first electric push rod 222 to be stored in the chute. At this time, when the credit report reaches the squeezing roller 2311, the squeezing roller 2311 drives it to ensure its movement stability, and the rotation speed of the squeezing roller 2311 is synchronized with the credit report output speed.

[0065] In the meantime, see Figure 12As shown, a transfer groove 2314 is symmetrically formed at the bottom of the rotating plate 231. An auxiliary plate 233 is rotatably connected in the transfer groove 2314. An auxiliary roller 2331 is rotatably connected between the two auxiliary plates 233. A third motor 2332 is provided on the side where the auxiliary roller 2331 and the auxiliary plate 233 transfer. A second electric push rod 2333 is provided between the auxiliary plate 233 and the bottom wall of the rotating plate 231. One end of the second electric push rod 2333 is rotatably connected to the bottom wall of the rotating plate 231, and the other end is rotatably connected to the outer wall of the auxiliary plate 233. In this embodiment, the auxiliary roller 2331 can assist in driving the squeezing roller 2311, further ensuring the stability of the movement of the credit report.

[0066] In addition, driving can be performed in Example 3 to ensure that the credit report can smoothly enter the steering groove 2211 for extrusion molding.

[0067] It is worth noting that the rotation speed of the auxiliary roller 2331 is synchronized with the rotation speed of the squeezing roller 2311 . Example 5

[0068] This embodiment discloses a blockchain-based enterprise credit report query system. Figure 14 The system includes an authentication query unit, an external monitoring access unit, a query environment identification unit, a blockchain storage unit, and a control unit; the authentication query unit is used to authenticate the identity of the querying person, specifically through ID card sensing or account password login authentication, and after successful authentication, retrieve the person's corporate credit information and generate a credit report that is stored in the blockchain storage unit for query; the external monitoring access unit is used to access the monitoring of the location where the query device is located and send it to the query environment identification unit; the query environment identification unit is used to identify the environment around the query device within the monitoring, wherein:

[0069] After the query environment recognition unit recognizes that there are more than three people queuing around the query device or someone is standing within a one-meter line (not limited by the number of people), the control unit controls the first electric push rod 222 to work, pushes out the telescopic plate 221 and enters the privacy mode, thereby accessing the monitoring of the location of the query device through the external monitoring access unit, and then the query environment recognition unit identifies the environment around the query device in the monitoring, and then cooperates with the control unit to realize automatic conversion to the privacy mode. After printing is completed, the first electric push rod 222 drives the telescopic plate 221 to reset. If the above situation is not met, printing is carried out in direct output mode.

[0070] It is worth noting that the external monitoring access unit accesses the monitoring of the location of the query device through the Internet of Things. Example 6

[0071] Considering that some people are more privacy-conscious and prefer to use private mode, please refer to Figure 15The authentication query unit further includes a mode selection module, which is used to select a mode through the touch display screen 300, wherein:

[0072] The touch screen display 300 is disposed on the top of the printer body 100 , and a scanning head 310 is disposed on the top of the touch screen display 300 .

[0073] The specific working principle is as follows:

[0074] When the query environment recognition unit does not meet the privacy mode, a selection box pops up on the touch screen 300, specifically a privacy mode selection box, a direct mode selection box and a mobile phone query box, wherein:

[0075] The privacy mode selection box is used to enter the privacy module;

[0076] The direct output mode selection box is used to enter the direct output module;

[0077] The query box on the mobile phone is used to control the scanning head 310 to scan the QR code on the mobile phone, and then send the credit report stored in the blockchain storage unit to the mobile phone without printing.

[0078] It is worth noting that the second motor 2321 , the first motor 2312 and the third motor 2332 in the privacy mode and the direct output mode are all servo motors and are controlled by the control unit. Example 7

[0079] A blockchain-based enterprise credit report query method includes the following steps:

[0080] S1. The authentication query unit authenticates the identity of the querying person;

[0081] S2. After successful authentication, the authenticated enterprise credit information is retrieved and a credit report is generated and stored in the blockchain storage unit;

[0082] S3, the external monitoring access unit accesses the monitoring of the location where the query device is located;

[0083] S4. The query environment identification unit identifies the environment surrounding the query device within the monitoring area, wherein:

[0084] If there are more than three people queuing around the query device or someone is standing within the one-meter line, the control unit controls the first electric push rod 222 to work and pushes out the telescopic plate 221.

[0085] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
