Description

Technical Field

[0001] The utility model relates to the technical field of scanners, in particular to a novel passport scanner. Background Art

[0002] A scanner is a device that uses photoelectric technology and digital processing technology to convert graphic or image information into digital signals by scanning. Scanners are usually used as external instruments and equipment for computers. They capture images and convert them into digital input devices that can be displayed, edited, stored and output by computers. Scanners can scan photos, text pages, drawings, art drawings, photographic negatives, film films, and even three-dimensional objects such as textiles, sign panels, and printed circuit board samples. They can extract and convert original lines, graphics, text, photos, and flat objects into devices that can be edited and added to files.

[0003] An existing scanner (publication number: CN220108060U) has at least the following disadvantages:

[0004] When the above patent is in use, the placement of products through the return plate is facilitated by the provision of the return plate, which facilitates the placement of product parts, makes the product scanning process more convenient, and reduces the quality of product scanning affected by the LED light placed inside the base. Since the scanner in the above patent is placed directly on the desktop, the desktop is relatively smooth and the scanner body is light, the scanner is not fixed to the desktop. During use, the user will manually operate the scanner, and manual operation will cause the scanner to move or shake, reducing the accuracy and stability of the scan. Utility Model Content

[0024] Reference Figure 1-Figure 5A novel passport scanner comprises a base 1, wherein four corners of the lower surface of the base 1 are fixedly mounted with suction cups 2, a slide groove 16 is provided inside the base 1, the slide groove 16 is arranged at the middle position of the base 1, four air flow channels 15 are provided inside the base 1, the top end of the suction cup 2 passes through the lower surface of the base 1 and is connected with the air flow channel 15, the air flow channel 15 is connected with the inside of the slide groove 16, a piston plate 17 is slidably mounted on the inner wall of the slide groove 16, an air hole 18 is provided inside the base 1, one end of the air hole 18 is connected with the inside of the slide groove 16, and the air flow channel 15 is connected with the inside of the slide groove 16. The other end of the hole 18 passes through the outer surface of the base 1. The base 1 is provided with a driving mechanism for driving the piston plate 17 to slide. The driving mechanism includes two support blocks 6 symmetrically fixedly installed on the upper surface of one side of the base 1. A rotating shaft 7 is rotatably installed between the two support blocks 6. A gear 8 is fixedly installed on the outer surface of the rotating shaft 7. A rack 9 is slidably inserted on the side of the base 1 close to the gear 8. One end of the rack 9 passes through the inner wall of the slide groove 16 and is fixedly installed on the outer surface of the piston plate 17. An opening 10 is opened on the outer surface of the base 1 close to the gear 8. The gear 8 passes through the opening 10 and meshes with the rack 9.

[0025] The user opens the cover 3, and the cover 3 drives the rotating shaft 7 to rotate through the rotating block 13, so that the rotating shaft 7 drives the gear 8 to rotate, and the gear 8 drives the rack 9 to slide in the direction close to the air hole 18, so that the rack 9 drives the piston plate 17 to slide in the direction close to the air hole 18, and the air inside the slide groove 16 is discharged from the air hole 18 through the piston plate 17, so that negative pressure is formed inside the suction cup 2, and then the suction cup 2 will tightly adsorb the desktop, thereby fixing the position of the device. When using the scanner, the device can be fixed at a specified position on the desktop through this device, so that the scanner can be prevented from moving or shaking during use, thereby ensuring the accuracy and stability of the scanning; when the cover 3 is closed, air can enter the interior of the suction cup 2 from the air hole 18, and the negative pressure state inside the suction cup 2 is released.

[0026] In this embodiment, two rotating blocks 13 are symmetrically fixedly installed on the outer surface of the rotating shaft 7, and two recesses 11 are provided on the upper surface of the base 1 near the rotating block 13. Spring plungers 12 are inserted into the inner walls of one side of the two recesses 11, and steel balls 19 are slidably installed on the inner wall of the spring plunger 12. A spring 20 is provided inside the spring plunger 12, and the spring 20 is arranged between the steel ball 19 and the bottom wall of the spring plunger 12. A through hole is provided at one end of the spring plunger 12 near the steel ball 19, and the diameter of the through hole is smaller than the diameter of the steel ball 19. A spherical groove 14 is provided on the outer surface of the rotating block 13 relative to the spring plunger 12, and the spherical groove 14 is matched with the steel ball 19.

[0027] When a part of the rotating block 13 rotates to the inside of the sink 11, the steel ball 19 leaking out from the end of the spring plunger 12 will be pressed into the inside of the spherical groove 14 on the surface of the rotating block 13. At this time, the user will feel obvious resistance and then stop rotating the cover plate 3. The position of the cover plate 3 can be fixed easily through this device.

[0028] In this embodiment, the cover plates 3 are fixedly mounted on the upper surfaces of the two rotating blocks 13 . The included angle between the cover plates 3 and the rotating blocks 13 is 90°. The 90° setting facilitates the partial outer surface of the rotating blocks 13 to rotate into the interior of the sink 11 .

[0029] In this embodiment, a notch is provided on the lower surface of the cover plate 3 away from the rotating block 13, and a folding plate 4 is rotatably installed on the inner wall of the notch. A scanning camera 5 is provided on the lower surface of the folding plate 4. The rotational installation method of the cover plate 3 is a damping installation, which ensures that the cover plate 3 can stop at any time during rotation and keep the rotating position unchanged.

[0030] After fixing the cover plate 3, the user opens the folding plate 4 to expose the scanning camera 5, adjusts the position of the scanning camera 5 and the base 1 through the damping installation of the folding plate 4, and then scans the passport information.

[0031] It should be noted that when the utility model is in use, the user puts the device on a designated desktop so that the suction cup 2 contacts the desktop, and the user opens the cover plate 3. The cover plate 3 drives the rotating shaft 7 to rotate through the rotating block 13, so that the rotating shaft 7 drives the gear 8 to rotate, and the gear 8 drives the rack 9 to slide in the direction close to the air hole 18, so that the rack 9 drives the piston plate 17 to slide in the direction close to the air hole 18, and the air inside the slide groove 16 is discharged from the air hole 18 through the piston plate 17, so that negative pressure is formed inside the suction cup 2, and then the suction cup 2 will tightly adsorb the desktop, thereby fixing the position of the device. When using the scanner, the device can be fixed at a designated position on the desktop through the device to prevent the scanner from being stuck during use. When the cover 3 is moved or shaken, the accuracy and stability of the scan are ensured; when the cover 3 is closed, air can enter the interior of the suction cup 2 from the air hole 18, and the negative pressure state inside the suction cup 2 is released; when a part of the rotating block 13 rotates to the interior of the sink 11, the steel ball 19 leaking from the end of the spring plunger 12 will be pressed into the interior of the spherical groove 14 on the surface of the rotating block 13. At this time, the user will feel obvious resistance, and then stop rotating the cover 3. The position of the cover 3 is easily fixed by this device; after fixing the cover 3, the user opens the folding plate 4 to expose the scanning camera 5, adjusts the position of the scanning camera 5 and the base 1 through the damping installation of the folding plate 4, and then the passport information can be scanned.
