Description

Technical Field

[0001] This utility model relates to the field of queuing display screen technology, and in particular to a queuing display screen for reporting queuing numbers. Background Technology

[0002] In hospitals, the queuing display screen serves as a core device guiding users through the process, and its adaptability in terms of viewing angle directly impacts user experience and service efficiency. In such scenarios, users are often positioned in different locations, such as in front of a single row of windows or in multiple waiting areas, resulting in significant differences in their viewing angles. Furthermore, some scenarios require switching between landscape and portrait display modes depending on the window layout to optimize information presentation. Therefore, the screen's angle adjustment function becomes a critical design requirement. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a reporting and queuing display screen.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a reporting and numbering display screen, comprising a display screen, a support part, an extension part, a mounting plate, and a barcode scanner. The support part includes a vertical pole and a base frame. The back of the display screen is detachably connected to the vertical pole, which extends vertically. The bottom end of the vertical pole is detachably connected to a horizontally arranged base frame. The side of the base frame is provided with an extension part that extends radially outward along the base frame. The extension part can be inserted and removed from the base frame radially. When the extension part is inserted into the base frame, it can expand the support area of ​​the base frame. When the extension part is pulled out of the base frame, it facilitates the disassembly and assembly of the base frame. The mounting plate is fixedly sleeved on the outer circumference of the vertical pole, and the mounting plate is located on the side of the vertical pole closer to the display screen. The barcode scanner is fixedly mounted on the surface of the mounting plate away from the vertical pole, and the scanning end of the barcode scanner is oriented away from the vertical pole.

[0005] Preferably, the side of the base frame has an insertion hole that extends through the thickness of the base frame, and the extension part is an extension arm that is adapted to be inserted into the insertion hole. When the extension arm is fully inserted into the insertion hole, one end of the extension arm extends out of the base frame to increase the contact area between the base frame and the ground, thereby improving the support stability of the base frame for the uprights.

[0006] Preferably, the upper surface of the base frame has a locking hole communicating with the insertion hole, and the upper surface of the extension arm has a placement groove recessed along the height direction of the extension arm. The placement groove contains a card that can elastically extend and retract in the vertical direction. When the extension arm is inserted axially along the insertion hole, the card is squeezed and retracted into the placement groove by the inner wall of the base frame. When the extension arm is inserted to a preset position, the card is aligned with the locking hole, and the card pops out vertically upward under its own elastic force and locks into the locking hole, so as to achieve axial positioning of the extension arm and the base frame.

[0007] Preferably, the end of the extension arm away from the base frame has a recessed mounting groove along the length of the extension arm. A retaining spring is provided in the mounting groove along the depth of the mounting groove. One end of the retaining spring is fixedly connected to the bottom of the mounting groove, and the other end abuts against the bottom surface of the card. When the extension arm is inserted into the insertion hole, the retaining spring is compressed and generates an elastic restoring force along the direction of extension arm withdrawal. This elastic restoring force pushes the card to always have a tendency to move towards the card hole, so as to ensure reliable engagement between the card and the card hole.

[0008] Preferably, the lower surface of the extension arm has a threaded hole that extends through the extension arm along its height direction. A bolt is threaded through the threaded hole, and the bottom end of the bolt is fixedly connected to a pad that fits and abuts against the ground. When the bolt is tightened, the bolt can move up and down along the axial direction of the threaded hole, thereby driving the pad to move synchronously in the vertical direction to adjust the support height of the extension arm and adapt to uneven ground.

[0009] Preferably, a rotating component for adjusting the display angle is provided between the display screen and the support pole. The rotating component includes a connecting frame, a rotating shaft, and a connecting plate. The connecting frame is fixedly mounted on the back of the display screen. A rotating shaft extending horizontally is fixedly mounted on the side of the connecting frame away from the display screen. One end of the connecting plate is rotatably sleeved on the outer circumference of the rotating shaft through a bearing. The other end of the connecting plate is fixedly connected to the top of the support pole, so as to realize the horizontal rotation of the display screen around the rotating shaft, thereby adjusting the orientation angle of the display screen.

[0010] Preferably, a guide rod extending radially along the rotating shaft is fixed on the upper surface of the connecting plate, a positioning plate is slidably sleeved on the outer circumferential surface of the guide rod, a positioning block is fixed on the side of the positioning plate facing the rotating shaft, four slots adapted to the positioning blocks are evenly opened on the outer circumferential surface of the rotating shaft, a return spring is sleeved on the outer circumferential surface of the guide rod, one end of the return spring is fixedly connected to the side of the connecting plate near the fixed end of the guide rod, and the other end is fixedly connected to the side of the positioning plate away from the rotating shaft. The return spring is always in a stretched state and generates a pulling force along the guide rod towards the rotating shaft. This pulling force pulls the positioning plate to slide along the axial direction of the guide rod, so that the positioning block is locked into the corresponding slot, thereby locking the rotation angle of the rotating shaft and fixing the horizontal or vertical display state of the display screen.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the rotating structure between the display screen and the support pole allows for horizontal adjustment of the display screen via a rotating shaft. Combined with a locking mechanism consisting of a positioning plate, positioning block, return spring, and slots, pulling the positioning plate unlocks the rotating shaft to adjust the angle. Once released, the return spring automatically engages the positioning block in the slot for fixation, making operation convenient. Simultaneously, four evenly spaced slots on the outer circumference of the rotating shaft support switching between landscape and portrait modes for the display screen. Whether users are in different locations within the lobby or in different usage scenarios (such as single-row windows or multi-row waiting areas), users can clearly view the screen content.

[0019] Example 1, such as Figure 1-5As shown, a numbering display screen includes a display screen 4, a support section, an extension section, a mounting plate 3, and a barcode scanner. The support section consists of a vertical pole 2 and a base frame 1. The back of the display screen 4 is detachably connected to the vertical pole 2 via bolts or snap-fit ​​structures. The vertical pole 2 extends vertically to support the display screen 4. The bottom end of the vertical pole 2 is also detachably connected to the horizontally positioned base frame 1. Common detachable connection structures include bolt connections or snap-fit ​​connections, facilitating subsequent disassembly, transportation, or maintenance and replacement. The side of the base frame 1 is provided with an extension section extending radially outward along the base frame 1. The extension section can be inserted and removed from the base frame 1 in the radial direction. When it is necessary to improve the support stability of the base frame 1, the extension section is inserted into the base frame 1. The portion of the extension section extending beyond the base frame 1 increases the contact area between the base frame 1 and the ground. When it is necessary to disassemble, assemble, or store the base frame 1, the extension section is pulled out of the base frame 1, reducing the overall space occupied by the base frame 1. Mounting plate 3 is fixedly fitted onto the outer circumference of pole 2. The mounting position of mounting plate 3 is located on the side of pole 2 closest to display screen 4, ensuring that the barcode scanner can be installed at a height convenient for user operation. The barcode scanner is installed on the surface of mounting plate 3 away from pole 2 by screws or clips, and the scanning end of the barcode scanner faces away from pole 2 to avoid pole 2 obstructing the scanning area, making it convenient for users to scan the ticket or mobile phone QR code. When users scan a code to register, they need to obtain the corresponding voucher in advance. This voucher can be a paper queue number (with a unique QR code / barcode) or an electronic voucher (such as a dynamic code generated by the mobile reservation interface). Users should hold the voucher with the code facing the scanning end of the scanner, keeping the distance between the code and the scanner within a reasonable range (usually 5-15 cm). The built-in image recognition module of the scanner will automatically capture and decode the code information. At the same time, the scanner surface will have an indicator light and a buzzer. If the scan is successful, the indicator light will light up green and the buzzer will emit a short beep. If the scan fails (e.g., the code is blurry, the tilt angle is too large, or it is outside the recognition range), the indicator light will light up red and the buzzer will emit two consecutive beeps. In this case, users can adjust the position or distance of the voucher and try scanning again.

[0020] The base frame 1 has a through-hole extending along its thickness on its side. The shape of the through-hole matches the shape of the extension, which is specifically an extension arm 12. The size of the extension arm 12 matches the through-hole, allowing it to be inserted precisely into the through-hole. When the extension arm 12 is fully inserted into the through-hole, one end of the extension arm 12 extends out of the base frame 1. The extended part, together with the base frame 1, forms a larger support surface, thereby increasing the contact area between the base frame 1 and the ground. This further enhances the stability of the base frame 1 in supporting the upright 2, preventing the entire display screen from tipping over due to a shift in the center of gravity or external force.

[0021] The upper surface of the base frame 1 is provided with a locking hole 13 that communicates with the insertion hole. The position of the locking hole 13 corresponds to the fixed position after the extension arm 12 is inserted. The upper surface of the extension arm 12 is provided with a placement groove 15 that is recessed along the height direction of the extension arm 12. A card 16 that can elastically extend and retract in the vertical direction is installed in the placement groove 15. The card 16 can be made of elastic plastic or metal material and has a certain elastic deformation capability. When the extension arm 12 is inserted along the axial direction of the socket, the card 16 on the surface of the extension arm 12 will contact the inner wall of the socket of the base frame 1. As the extension arm 12 continues to be inserted, the inner wall of the base frame 1 will exert a squeezing force on the card 16, causing the card 16 to retract into the placement groove 15, thus preventing the card 16 from obstructing the insertion of the extension arm 12. When the extension arm 12 is inserted into the preset fixed position, the placement groove 15 on the extension arm 12 will be aligned with the card hole 13 on the base frame 1. At this time, the squeezing force of the inner wall of the base frame 1 on the card 16 will disappear, and the card 16 will pop up vertically under its own elastic force. The top of the card 16 will be inserted into the card hole 13, thereby achieving axial positioning between the extension arm 12 and the base frame 1 and preventing the extension arm 12 from accidentally coming out of the socket during use.

[0022] The end of the extension arm 12 furthest from the base frame 1 has a recessed mounting groove 17 along its length. The depth and width of the mounting groove 17 are adapted to the size of the retaining spring 18. The retaining spring 18 is installed in the mounting groove 17 and arranged along its depth. One end of the retaining spring 18 is fixedly connected to the bottom of the mounting groove 17 by welding or snap-fit, and the other end abuts against the bottom surface of the card 16. When the extension arm 12 is inserted into the insertion hole, the card 16 is squeezed and compresses the retaining spring 18 towards the mounting groove 17, putting the retaining spring 18 in a compressed state. The compressed retaining spring 18 generates an elastic restoring force along the direction of extension arm 12 pull-out. This elastic restoring force continuously pushes the card 16, ensuring that the card 16 always tends to move towards the card hole 13. Even if it is subjected to slight vibration or external force during use, it can ensure that the card 16 and the card hole 13 remain reliably engaged, further improving the stability of the connection between the extension arm 12 and the base frame 1.

[0023] The lower surface of the extension arm 12 has a threaded hole extending along its height. A bolt is threaded through the hole, and the bolt's specifications match the threaded hole, allowing it to move up and down within the hole by screwing. A foot 14 is fixedly connected to the bottom of the bolt by welding or threaded connection. The foot 14 is made of rubber or non-slip plastic, providing good anti-slip performance and increasing friction with the ground. When the display screen is placed on uneven ground, screwing the bolt causes it to move up and down along the axial direction of the threaded hole, which in turn moves the foot 14 vertically, adjusting the support height of the corresponding position on the extension arm 12. This ensures the base frame 1 remains level and prevents the display screen from tilting due to uneven ground.

[0024] A rotating component for adjusting the display angle is provided between the display screen 4 and the support pole 2. The rotating component consists of a connecting frame 5, a rotating shaft 6, and a connecting plate. The connecting frame 5 is fixedly installed on the back of the display screen 4 by screws or welding. A rotating shaft 6 extending horizontally is fixedly installed on the side of the connecting frame 5 away from the display screen 4. The rotating shaft 6 can be integrally formed with the connecting frame 5 or fixed by a key connection. One end of the connecting plate is rotated and sleeved on the outer circumference of the rotating shaft 6 by a bearing. The bearing can be a deep groove ball bearing to ensure that the rotating shaft 6 can rotate smoothly. The other end of the connecting plate is fixedly connected to the top of the support pole 2 by bolts or welding. With this structure, the display screen 4 can rotate horizontally around the axis of the rotating shaft 6, thereby adjusting the orientation angle of the display screen 4 to meet the needs of users in different directions to view the content of the display screen.

[0025] Display screen 4 will show the scanned reporting information in sections. The upper half of the screen is the "Current Reporting User Information Area," which displays the user's queue number (e.g., "Queue Number: B025"), name abbreviation (e.g., "Name: XXX"), and real-time reporting status (e.g., "Status: Scanned and Pending Processing") in large, bold, dark blue font. The background is set to light gray to enhance text readability. The lower half of the screen is the "Reporting Guidance Area," which displays the corresponding processing window number (e.g., "Please go to processing window number 2") and estimated waiting time (e.g., "Estimated waiting time: 8 minutes") in medium-sized black font. At the same time, it will slowly scroll through the required documents (e.g., "Please present your original ID card when processing"). The right edge of the screen is set as the "Historical Reporting Record Area," which displays the queue number range of users who have completed reporting in small gray font (e.g., "Completed Reporting: B001-B024"), making it convenient for users to quickly understand the queue progress. Once a user completes the reporting process, staff will update the user's reporting status through the backend system. Display screen 4 will then simultaneously update the user's "Current Reporting User Information Area" to "Status: Reporting Completed," and automatically switch to the information of the next user who has scanned the code after 30 seconds, ensuring that the displayed content is accurate and up-to-date.

[0026] A guide rod 10 extending radially along the rotating shaft 6 is fixed to the upper surface of the connecting plate by welding or screws. A positioning plate 8 is slidably fitted on the outer circumferential surface of the guide rod 10. The positioning plate 8 and the guide rod 10 are fitted with a clearance fit to ensure that the positioning plate 8 can slide smoothly along the guide rod 10. A positioning block 9 is fixedly fitted on the side of the positioning plate 8 facing the rotating shaft 6 by welding or integral molding. Four slots 7 that are adapted to the positioning blocks 9 are evenly opened on the outer circumferential surface of the rotating shaft 6. The shape of the slots 7 matches the shape of the positioning blocks 9 to ensure that the positioning blocks 9 can be smoothly inserted into the slots 7. A return spring 11 is fitted on the outer circumferential surface of the guide rod 10. One end of the return spring 11 is fixedly connected to the side of the connecting plate near the fixed end of the guide rod 10, and the other end is fixedly connected to the side of the positioning plate 8 away from the rotating shaft 6. The reset spring 11 is always in a stretched state, generating a pulling force along the guide rod 10 towards the rotating shaft 6. This pulling force pulls the positioning plate 8 to slide along the axial direction of the guide rod 10 towards the rotating shaft 6, causing the positioning block 9 on the positioning plate 8 to engage in the corresponding slot 7, thereby locking the rotation angle of the rotating shaft 6 and fixing the landscape or portrait display state of the display screen 4. When it is necessary to adjust the landscape or portrait state of the display screen 4, pull the positioning plate 8 away from the rotating shaft 6. The positioning plate 8 compresses the reset spring 11 and causes the positioning block 9 to disengage from the slot 7. At this time, the rotating shaft 6 can rotate freely. After adjusting to the required angle, release the positioning plate 8. The pulling force of the reset spring 11 will cause the positioning block 9 to re-engage in the corresponding slot 7, completing the angle locking and ensuring that users can clearly see the report information from different viewing angles.

[0027] The working principle is as follows: When assembling the report number display screen, the bottom end of the upright 2 is first connected and fixed to the base frame 1 through a detachable structure. Then, the back of the display screen 4 is connected to the top of the upright 2 through a rotating component. Subsequently, the extension arm 12 is inserted into the insertion hole on the side of the base frame 1. During the insertion process, the card 16 on the extension arm 12 is squeezed and contracted to the placement groove 15 by the inner wall of the base frame 1 and compresses the clamping spring 18. When the extension arm 12 is inserted into the preset position, the card 16 pops out under the elastic force of the clamping spring 18 and locks into the card hole 13 of the base frame 1, thereby fixing the extension arm 12 to the base frame 1. Then, according to the flatness of the ground, the bolts on the lower surface of the extension arm 12 are tightened, which drives the pad 14 to rise and fall to keep the base frame 1 level. After the mounting plate 3 is fixed at the position of the upright 2 near the display screen 4, the barcode scanner is installed on the surface of the mounting plate 3 away from the upright 2 and the scanning end is adjusted to face the screen. At the same time, the signal connection between the barcode scanner and the internal display system of the display screen 4 is completed to ensure that the scanned information can be transmitted to the display screen in real time.

[0028] During use, when a user scans a QR code to report, they hold the report voucher (paper or electronic) with the QR code / barcode and align it with the scanning terminal of the scanner. After successful recognition, the scanner provides feedback through indicator lights and a buzzer, and simultaneously transmits the user information to the display screen 4. The display screen shows information such as the user's queue number, name abbreviation, report status, processing window, and waiting time in sections. If it is necessary to adjust the orientation of the display screen 4 so that users in different positions can view the report information, pull the positioning plate 8 away from the pivot 6. The positioning block 9 will disengage from the slot 7 of the pivot 6. Rotate the display screen 4 to the desired orientation. After releasing the positioning plate 8, the return spring 11 pulls the positioning plate 8 to slide, causing the positioning block 9 to re-engage into the corresponding slot 7, locking the orientation of the display screen 4. If it is necessary to switch the display screen 4 to landscape or portrait mode to adapt to different viewing needs, similarly, pull the positioning plate 8 to disengage the positioning block 9 from the slot 7, rotate the pivot 6 to adjust the horizontal or vertical angle of the display screen 4, and release the positioning plate 8 to lock the orientation through the cooperation of the positioning block 9 and the slot 7. Once a user completes their reporting process and the staff updates the backend status, display screen 4 will simultaneously update the user's reporting status and switch to the next user's information after a set time. When the display screen needs to be disassembled for storage or repair, first disconnect the barcode scanner from the display system and remove the barcode scanner. Then, pull the positioning plate 8 to unlock the pivot 6 and disassemble display screen 4 from the support pole 2. Pull out the extension arm 12, and finally disassemble support pole 2 from the base frame 1 to complete the disassembly operation. The entire process, through the coordinated action of various components, achieves stable support for the display screen, barcode scanning for reporting, information partitioning display, angle adjustment, and convenient assembly and disassembly functions, meeting the usage needs in reporting queuing scenarios.
