Abstract
Description
Technical Field
[0001] This utility model relates to the field of barcode scanning equipment technology, specifically a handheld barcode scanning device. Background Technology
[0002] Handheld barcode scanners are portable data collection devices that enable rapid information entry by scanning barcodes or QR codes. They are widely used in retail, warehousing, and logistics scenarios, supporting 1D / 2D barcode scanning and reading information from paper labels, mobile phone screens, and other media. Some models also support NFC or RFID read / write functions.
[0003] Existing handheld scanning devices have a fixed scanning head that cannot be adjusted. Users need to manually rotate their wrists to adjust the scanning angle to complete the scan. This operation can cause hand fatigue during prolonged use. In addition, the outer protective shell of the scanning head inevitably wears down after long-term use, resulting in insufficient clarity and scanning failures. Therefore, we propose a handheld scanning device to solve the problems mentioned above. Utility Model Content
[0004] The purpose of this utility model is to provide a handheld barcode scanning device to solve the problem mentioned in the background art that the scanning head of the existing handheld scanning device is fixed during use and cannot be adjusted. It requires manual wrist rotation to adjust the scanning angle to achieve scanning. Such operation causes hand fatigue for users after long-term work. At the same time, the outer protective shell of the scanning head of the existing scanning device is inevitably worn after long-term use, resulting in insufficient clarity and scanning failure.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a handheld barcode scanner, comprising a handle and a scanning head. A U-shaped plate is mounted on the top of the handle, with the opening of the U-shaped plate facing the side. A rotating block is rotatably connected inside the U-shaped plate, with one side of the rotating block near the U-shaped plate being arc-shaped. A connecting block is mounted on the other side of the rotating block, and fixing plates are mounted at both ends of the other side of the connecting block. A second fixing rod is mounted between the two fixing plates, with both ends of the second fixing rod rotatably connected to the fixing plates via second bearing seats. A first bevel gear is mounted on the outer wall of the second fixing rod. A placement groove is provided on one side of the connecting block, and a second drive motor is mounted inside the placement groove. A second bevel gear is mounted on the output shaft of the second drive motor, meshing with the first bevel gear. Rotating plates are mounted at both ends of the outer wall of the second fixing rod, and the scanning head is mounted on the other side of the rotating plate.
[0006] Preferably, the side of the fixing plate away from the connecting block is arc-shaped, and the side of the rotating plate near the connecting block is arc-shaped.
[0007] Preferably, a first fixing rod is installed inside the U-shaped plate, and the top and bottom of the first fixing rod are rotatably connected to the U-shaped plate through a first bearing seat. An internal groove is provided above the inside of the handle, and a first drive motor is installed inside the internal groove. The first fixing rod is installed on the output shaft of the first drive motor, and the rotating block is fixedly connected to the outer wall of the first fixing rod.
[0008] Preferably, a protective housing is snapped onto the other side of the scanning head, and a transparent plate is installed on one side of the protective housing.
[0009] Preferably, the scanning head has limit grooves at both ends on one side, a limit spring is installed inside the limit groove, a limit block is installed at the other end of the limit spring, a telescopic rod is installed inside the limit spring, and the protective housing has through grooves at both ends, with the limit block passing through the through grooves and located outside the protective housing.
[0010] Preferably, the limiting block has inclined surfaces on both sides of the end away from the limiting spring.
[0011] Preferably, an arc-shaped groove is provided on one side of the outer wall of the handle, and an anti-slip pad is installed inside the arc-shaped groove. The outer wall and bottom of the handle are provided with rounded corners.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] (1) This utility model drives the first fixed rod and the rotating block to rotate through the first drive motor. The rotating block can drive the scanning head to rotate around the first fixed rod in the left and right directions through the connecting block and the fixed plate. The second drive motor drives the second bevel gear to rotate. Through the meshing connection, the first bevel gear can be driven to rotate synchronously, thereby driving the second fixed rod and the rotating plates at both ends to swing up and down, thereby realizing the adjustment of the up and down tilt angle of the scanning head. This solves the problem that the scanning head of the existing handheld scanning equipment is fixed during use and cannot be adjusted. It requires manual rotation of the wrist to adjust the scanning angle to achieve scanning. Such operation causes hand fatigue to the user after a long period of work.
[0014] (2) By pushing the limit block out through the through slot of the protective shell and protruding to the outside, the protective shell can be locked. When the transparent plate is worn and the light transmittance decreases, the old protective shell can be removed by pressing the limit block to compress the limit spring. This solves the problem that the outer protective shell of the scanning head of the existing handheld scanning equipment is inevitably worn after long-term use, resulting in insufficient clarity and scanning failure.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figure 1-4 This utility model provides one embodiment: a handheld barcode scanner, including a handle 1 and a scanning head 17. A U-shaped plate 3 is mounted on the top of the handle 1, and the opening of the U-shaped plate 3 is oriented to the side. A rotating block 7 is rotatably connected inside the U-shaped plate 3. Please refer to [link to relevant documentation]. Figure 2The U-shaped plate 3 has a first fixing rod 4 installed inside. The top and bottom of the first fixing rod 4 are rotatably connected to the U-shaped plate 3 through the first bearing seat 5. The handle 1 has an internal groove 2 at the top inside. The internal groove 2 has a first drive motor 6 installed inside. The first fixing rod 4 is installed on the output shaft of the first drive motor 6. The outer wall of the first fixing rod 4 is fixedly connected to a rotating block 7. The rotating block 7 is arc-shaped on one side near the U-shaped plate 3. A connecting block 8 is installed on the other side of the rotating block 7. Fixing plates 9 are installed at both ends of the other side of the connecting block 8. A second fixing rod 10 is installed between the two fixing plates 9. The two ends of the second fixing rod 10 are rotatably connected to the fixing plates 9 through second bearing seats 11. A first bevel gear 12 is installed on the outer wall of the second fixing rod 10. A placement groove 13 is provided on one side of the connecting block 8. A second drive motor 14 is installed inside the placement groove 13. A second bevel gear 15 is installed on the output shaft of the second drive motor 14. The second bevel gear 15 meshes with the first bevel gear 12. Rotating plates 16 are installed at both ends of the outer wall of the second fixing rod 10. A scanning head 17 is installed on the other side of the rotating plate 16. Please refer to [link to relevant documentation]. Figure 2 and Figure 4 The fixed plate 9 is curved on the side away from the connecting block 8, and the rotating plate 16 is curved on the side closer to the connecting block 8. During use, the device uses the first drive motor 6 and the second drive motor 14 to drive the mechanical transmission structure, enabling the scanning head 17 to rotate left and right and tilt up and down, replacing manual wrist rotation. After the first drive motor 6 starts, its output shaft drives the first fixed rod 4 to rotate. The first fixed rod 4 is rotatably connected to the U-shaped plate 3 via the first bearing seat 5, ensuring its rotational stability. The rotating block 7, fixed to the outer wall of the first fixed rod 4, rotates synchronously with it. The rotating block 7, through the connecting block 8 and the fixed plate 9, drives the scanning head 17 to rotate left and right around the first fixed rod 4. The side of the rotating block 7 closer to the U-shaped plate 3 is curved to avoid interference with the inner wall of the U-shaped plate 3 during rotation, ensuring smooth adjustment. After the second drive motor 14 starts, its output shaft drives the second bevel gear 15 to rotate. Through the meshing connection between the second bevel gear 15 and the first bevel gear 12, the first bevel gear 12 rotates synchronously, thereby driving the second fixed rod 10 to rotate. The rotation of the second fixed rod 10 causes the rotating plates 16 at both ends to swing up and down, ultimately achieving the adjustment of the vertical tilt angle of the scanning head 17. The side of the fixed plate 9 away from the connecting block 8 is arc-shaped, and the side of the rotating plate 16 near the connecting block 8 is also arc-shaped, effectively preventing collisions with other components when the scanning head 17 swings up and down. Please refer to [link / reference]. Figure 1A protective housing 18 is snapped onto the other side of the scanning head 17, and a transparent plate 19 is installed on one side of the protective housing 18. The protective housing 18 covers the scanning end face of the scanning head 17, while the transparent plate 19 does not obstruct the scanning light path. This also prevents fabric and thread ends from directly rubbing against the scanning head surface during garment quality inspection, thus avoiding scratches to the lens. The snap-fit design between the protective housing 18 and the scanning head 17 facilitates the replacement of both the protective housing 18 and the transparent plate 19.
[0022] Please see Figure 3 Limiting grooves 20 are provided at both ends on one side of the scanning head 17. A limiting spring 21 is installed inside the limiting groove 20, and a limiting block 22 is installed at the other end of the limiting spring 21. A telescopic rod 23 is installed inside the limiting spring 21. Through grooves 25 are provided at both ends of the protective housing 18, and the limiting block 22 passes through the through grooves 25 and is located outside the protective housing 18. Please refer to [link / reference]. Figure 4 The limiting block 22 has inclined surfaces 24 on both sides of the end away from the limiting spring 21. When the protective housing 18 is snapped onto the outside of the scanning head 17, the limiting spring 21 inside the limiting grooves 20 on both sides of the scanning head 17 pushes the limiting block 22 out, which passes through the through groove 25 of the protective housing 18 and protrudes outward, locking the protective housing 18. The extension rod 23 prevents the limiting spring 21 from shifting at an angle. When the transparent plate 19 is worn, causing a decrease in light transmittance, pressing the limiting block 22 will compress the limiting spring 21 after the inclined surface 24 is stressed, allowing the old protective housing 18 to be removed. After replacing the new protective housing 18, the limiting block 22 will automatically pop out under the spring force and snap into the through groove 25. The entire replacement process requires no tools, avoiding scanning failures caused by wear on the protective housing 18 and the transparent plate 19.
[0023] Please see Figure 1 The handle 1 has an arc-shaped groove 26 on one side of its outer wall, and an anti-slip pad 27 is installed inside the arc-shaped groove 26. The outer wall and bottom of the handle 1 are rounded. The arc-shaped groove 26 of the handle 1 is designed to fit the operator's palm to form a natural grip arc. The anti-slip pad 27 increases friction to prevent the device from slipping. The rounded corners of the outer wall and bottom of the handle 1 effectively reduce hand pressure.
[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
