Description

Technical Field

[0001] This utility model relates to the field of scanner technology, and in particular to a document scanner with adjustment function. Background Technology

[0002] A scanner is a device that captures images. As a computer peripheral product that integrates opto-mechatronics, the scanner is the third largest computer input device after the mouse and keyboard. It can convert images into digital formats that computers can display, edit, store and output, making it a very powerful input device.

[0003] Traditional document scanners often lack adjustment functions, and fixed-scan document scanners cannot adjust the scanning position according to the thickness and size of the actual documents, which limits the scanning process, increases the scanning difficulty for staff, and fails to meet customer needs.

[0004] Therefore, those skilled in the art have provided a document scanner with adjustable functions to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the issue of lacking adjustment functionality, this invention provides a document scanner with adjustment capabilities.

[0006] This utility model provides a document scanner with adjustable functions, employing the following technical solution:

[0007] A document scanner with adjustable function includes a base, an adjustment frame fixedly connected to the top left side of the base, a servo motor fixedly installed at the bottom of the inner cavity of the adjustment frame, a screw fixedly connected to the output end of the servo motor, a lifting frame slidably connected to the outer surface of the adjustment frame, a rectangular plate threadedly connected to the outer surface of the screw, a fixed connection between the top of the rectangular plate and the lifting frame, a horizontal plate fixedly connected to the top of the lifting frame, a movable plate slidably connected to the bottom of the horizontal plate, a stud fixedly connected to the top of the movable plate, the top of the stud penetrating the horizontal plate and threadedly connected to a limit nut, and a scanner body fixedly installed at the bottom of the horizontal plate.

[0008] By adopting the above technical solution, when the staff needs to adjust the scanning position of the scanner body laterally according to the size and thickness of the document to be scanned, the staff moves the movable plate laterally, which causes the movable plate to move the scanner body laterally. When the scanner body moves laterally to the appropriate scanning position, the staff rotates the movement limit nut, which causes the limit nut to rotate and move the rubber pad on the outer surface of the stud thread to fit tightly with the connection of the horizontal plate, thereby limiting the connection between the movable plate and the horizontal plate and completing the lateral adjustment of the scanning position of the scanner body.

[0009] When the scanning position of the scanner body needs to be vertically adjusted according to the size and thickness of the document to be scanned, the operator activates the external controller of the servo motor, which drives the screw to rotate on the inner surface of the rectangular plate. This causes the rectangular plate to move the lifting frame vertically on the outer surface of the adjustment frame. At the same time, the lifting frame moves the horizontal plate vertically, which in turn moves the movable plate and the scanner body vertically. This allows the scanner body to be moved vertically to the appropriate height, thus completing the vertical adjustment of the scanner body's scanning position.

[0010] Optionally, a rubber pad is fixedly connected to the bottom of the limiting nut, and the outer surface of the rubber pad is tightly fitted to the connection point of the cross plate.

[0011] By adopting the above technical solution, the rubber pad can increase the friction between the limiting nut and the cross plate, thereby improving the stability of the contact limit.

[0012] Optionally, the top of the horizontal plate is provided with a movable groove for use with a stud, and the stud is located in the inner cavity of the movable groove.

[0013] By adopting the above technical solution, the movable groove facilitates the movement of the stud while also limiting its movement.

[0014] Optionally, slide rails are fixedly connected to the front and rear positions of the bottom of the horizontal plate, and the outer surface of the slide rails is slidably connected to the inner surface of the movable plate.

[0015] By adopting the above technical solution, the slide rail can guide and support the horizontal plate.

[0016] Optionally, guide plates are fixedly connected to the bottom of both sides of the rectangular plate, and guide grooves that cooperate with the guide plates are opened on both sides of the inner cavity of the adjustment frame. The outer surface of the guide plate is slidably connected to the inner surface of the guide groove.

[0017] By adopting the above technical solution, the guide plate and guide groove can guide and limit the rectangular plate.

[0018] Optionally, a protective pad is fixedly connected to the top of the adjustment frame, and the outer surface of the protective pad is tightly fitted to the connection of the lifting frame.

[0019] By adopting the above technical solution, the protective pad can provide protective support for the connection between the adjustment frame and the lifting frame.

[0020] Optionally, a handle is fixedly connected to the left side of the top of the cross plate, and the handle is concave.

[0021] By adopting the above technical solution, the handle design facilitates the movement of the device.

[0022] Optionally, the bottom of the base is provided with an anti-slip pad, and the anti-slip pad is bonded to the connection between the base and the anti-slip pad.

[0023] By adopting the above technical solution, the anti-slip pad can protect the base and increase the friction of the base, thereby improving the stability of placement.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. This utility model, by setting a horizontal plate, a movable plate, a stud, and a limiting nut, allows for convenient horizontal adjustment of the scanning position of the scanner body. By setting a base, an adjustment frame, a servo motor, a screw, a lifting frame, and a rectangular plate, it allows for convenient vertical adjustment of the scanning position of the scanner body. Through the above structure, the scanner body has the advantage of adjustment function, thereby meeting the needs of customers, avoiding limitations in scanning use, and reducing the scanning difficulty for staff.

[0026] 2. This utility model increases the friction between the limiting nut and the horizontal plate by setting a rubber pad, thereby improving the stability of the contact limiting. The moving groove facilitates the movement of the stud and limits its movement. The slide rail provides guidance and support for the horizontal plate. The guide plate and guide groove guide and limit the rectangular plate. The protective pad provides protection and support at the connection between the adjusting frame and the lifting frame. The handle facilitates the movement of the device. The anti-slip pad protects the base and increases its friction, thereby improving the stability of the placement. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] Please refer to Figure 1-5 A document scanner with adjustable function includes a base 1, an adjustment frame 2 fixedly connected to the top left side of the base 1, a servo motor 3 fixedly installed at the bottom of the inner cavity of the adjustment frame 2, a screw 4 fixedly connected to the output end of the servo motor 3, a lifting frame 5 slidably connected to the outer surface of the adjustment frame 2, a rectangular plate 6 threadedly connected to the outer surface of the screw 4, the top of the rectangular plate 6 being fixedly connected to the connection of the lifting frame 5, a horizontal plate 7 fixedly connected to the top of the lifting frame 5, a movable plate 8 slidably connected to the bottom of the horizontal plate 7, a stud 9 fixedly connected to the top of the movable plate 8, the top of the stud 9 penetrating the horizontal plate 7 and threadedly connected to a limit nut 10, and a scanner body 11 fixedly installed at the bottom of the horizontal plate 7.

[0036] In this embodiment: By setting a horizontal plate 7, a movable plate 8, a stud 9, and a limiting nut 10, the scanning position of the scanner body 11 can be easily adjusted horizontally. By setting a base 1, an adjustment frame 2, a servo motor 3, a screw 4, a lifting frame 5, and a rectangular plate 6, the scanning position of the scanner body 11 can be easily adjusted vertically. By setting the above structure, the scanner body 11 has the advantage of adjustment function, thereby meeting the needs of customers, avoiding limitations in scanning use, and reducing the scanning difficulty for staff.

[0037] A rubber pad 12 is fixedly connected to the bottom of the limiting nut 10. The outer surface of the rubber pad 12 is tightly fitted to the connection of the horizontal plate 7. A moving groove 13 is opened at the top of the horizontal plate 7 to cooperate with the stud 9. The stud 9 is located in the inner cavity of the moving groove 13. Slide rails 14 are fixedly connected to the front and rear positions of the bottom of the horizontal plate 7. The outer surface of the slide rail 14 is slidably connected to the inner surface of the movable plate 8. Guide plates 15 are fixedly connected to the bottom of the left and right sides of the rectangular plate 6. Guide grooves 16 are opened on the left and right sides of the inner cavity of the adjusting frame 2 to cooperate with the guide plates 15. The outer surface of the guide plates 15 is slidably connected to the inner surface of the guide grooves 16. A protective pad 17 is fixedly connected to the top of the adjusting frame 2. The outer surface of the protective pad 17 is tightly fitted to the connection of the lifting frame 5. A handle 18 is fixedly connected to the left side of the top of the horizontal plate 7. The handle 18 is concave. An anti-slip pad 19 is provided at the bottom of the base 1. The anti-slip pad 19 and the base 1 are bonded together.

[0038] The implementation principle of this utility model is as follows: When in use, the operator connects the device to the mains power. Then, the operator places the document to be scanned on the top of the base 1. Next, when the operator needs to adjust the scanning position of the scanner body 11 laterally according to the size and thickness of the document to be scanned, the operator moves the movable plate 8 laterally, so that the movable plate 8 drives the scanner body 11 to move laterally. At the same time, the movable plate 8 drives the stud 9 to slide on the inner surface of the moving groove 13. When the scanner body 11 moves laterally to the appropriate scanning position, the operator rotates the moving limit nut 10, so that the limit nut 10 drives the rubber pad 12 to rotate and move on the outer surface of the stud 9 and fit tightly against the connection of the horizontal plate 7, thereby limiting the connection between the movable plate 8 and the horizontal plate 7, and completing the lateral adjustment of the scanning position of the scanner body 11.

[0039] When the scanning position of the scanner body 11 needs to be vertically adjusted according to the size and thickness of the document to be scanned, the operator activates the external controller of the servo motor 3, causing the output end of the servo motor 3 to drive the screw 4 to rotate on the inner surface of the rectangular plate 6. This causes the rectangular plate 6 to drive the lifting frame 5 to slide vertically on the outer surface of the adjustment frame 2. At the same time, the lifting frame 5 drives the horizontal plate 7 to move vertically, causing the horizontal plate 7 to drive the movable plate 8 and the scanner body 11 to move vertically. This allows the scanner body 11 to move vertically to a suitable height, completing the vertical adjustment of the scanning position of the scanner body 11. Then, the operator activates the external controller of the scanner body 11, causing the scanner body 11 to scan the document to be scanned. This device is simple to operate and easy to adjust, thus meeting the needs of customers, avoiding limitations in scanning use, and reducing the scanning difficulty for operators.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
