Description

Technical Field

[0001] This utility model relates to the field of barcode reading technology, specifically a barcode reading device with a protective structure. Background Technology

[0002] A barcode reader is a device used to read barcode information. It uses an optical device to convert the barcode's bar and space information into electronic information, which is then translated into corresponding data information by a dedicated decoder.

[0003] For example, patent CN219476110U discloses a barcode reading device that can quickly read barcodes at different distances, which relates to the field of barcode reading technology. The key technical point of the solution is that it includes a support base, two clamps are fixedly connected to the side wall of the support base, and a recognition head is rotatably connected between the two clamps. The recognition head has a decoding chip, a control chip, a drive chip, a voice coil motor, a lens, and a photosensitive chip installed inside. A laser rangefinder and a viewfinder are embedded in the side wall of the recognition head. The decoding chip, drive chip, photosensitive chip, and laser rangefinder are all electrically connected to the control chip, and the voice coil motor is electrically connected to the drive chip.

[0004] With the above setup, existing technology uses a laser rangefinder to quickly adjust the lens position, eliminating the need for manual adjustment of the barcode position, resulting in faster zooming and the ability to quickly read barcodes at different distances. However, existing barcode reading devices have the following drawbacks during operation:

[0005] The aforementioned device adjusts the angle of the recognition head by rotating a handle to drive a worm gear, which in turn drives the teeth to rotate, thereby changing the angle of the recognition head. However, adjusting the angle of the recognition head by rotating the handle is too slow, and there is no limit to the handle's position. This causes the handle to rotate under external force, resulting in the recognition head angle changing automatically. Furthermore, after a period of use, dust accumulates on the end of the recognition head, causing the device to be unable to recognize barcodes. Utility Model Content

[0006] The present invention aims to provide a barcode reading device with a protective structure, mainly to solve the technical problem that the existing technology does not have the ability to protect the end of the reading head.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A barcode reading device with a protective structure includes a reading head and a support. Connecting plates are symmetrically fixedly connected to the side walls of the support. Rotating shafts are fixedly connected to both side walls of the reading head, and the ends of the rotating shafts are rotatably connected to the side walls of the connecting plates. A movable plate is slidably connected to the outer front wall of the reading head, and a cleaning brush is fixedly connected to the side wall of the movable plate. Rectangular grooves are symmetrically formed on the outer front wall of the reading head, and sliding components are provided on the inner side walls of the rectangular grooves. A power component is provided on the side walls of the reading head. A toothed groove is formed through the outer side wall of the connecting plate, and a limit component is provided on the inner side wall of the toothed groove.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When using this device, if it is necessary to clean the dust from the end of the recognition head, the power component is activated, which drives the sliding component to work. During the operation of the sliding component, the moving plate slides, thereby using the cleaning brush to clean the end of the recognition head and the lens. When it is necessary to adjust the angle of the recognition head, the limiting component is pulled outward, causing the limiting component to disengage from the tooth groove. Then, the rotating shaft and the connecting plate can rotate, thereby achieving the angle adjustment of this device by rotating the recognition head.

[0011] 2. Beneficial effects:

[0012] Existing technologies, by incorporating decoding chips, control chips, drive chips, voice coil motors, lenses, and photosensitive chips, eliminate the need for manual adjustment of barcode positions, offering faster zoom speeds and the ability to quickly read barcodes at different distances. However, these technologies lack protection for the end of the recognition head. This solution addresses this issue by using a power component that drives a sliding component. During this operation, the sliding component moves a moving plate, allowing a cleaning brush to clean the lens at the end of the recognition head, preventing dust accumulation that could hinder barcode reading. When the angle of the recognition head needs adjustment, pulling outwards on a limiting component disengages it from the toothed groove, allowing rotation between the rotating shaft and the connecting plate. This allows for angle adjustment of the device simply by rotating the recognition head.

[0013] Preferably, the sliding assembly includes a reciprocating lead screw that passes through and is rotatably connected to the inner wall of the rectangular groove. A slider is threadedly connected to the outer wall of the reciprocating lead screw, and the slider is slidably connected to the inner wall of the rectangular groove. The ends of the two sliders are fixedly connected to the two ends of the moving plate. When it is necessary to clean the dust at the end of the recognition head, the device can start the power assembly to drive the two reciprocating lead screws to rotate. During the rotation of the reciprocating lead screws, the sliders slide back and forth along the outer wall of the reciprocating lead screws. As the sliders move along the outer wall of the reciprocating lead screws, they drive the moving plate to move, thereby using a cleaning brush to clean the dust at the end of the recognition head, preventing dust from blocking the lens and causing the inability to read barcodes.

[0014] Preferably, the power assembly includes a motor fixedly connected to the side wall of the recognition head. A transmission wheel is symmetrically rotatably connected to the side wall of the recognition head. Two transmission wheels are respectively fixedly connected to the ends of two reciprocating lead screws. A belt is fitted onto the outer side wall of each of the two transmission wheels. The output end of the motor is fixedly connected to the outer side wall of one of the transmission wheels. When it is necessary to rotate both reciprocating lead screws simultaneously, the motor is started, driving one of the transmission wheels to rotate. During the rotation of one transmission wheel, the belt drives the other transmission wheel to rotate, thereby driving both reciprocating lead screws to rotate through the two rotating transmission wheels, achieving the purpose of simultaneous rotation of both reciprocating lead screws.

[0015] Preferably, the limiting component includes a gear movably connected to the inner sidewall of the tooth groove, a rectangular block fixedly connected to the end of the rotating shaft, and a sliding connection between the rectangular block and the gear. Multiple connecting posts are fixedly connected to the outer sidewall of the gear, and a toggle block is fixedly connected to the end of the connecting posts. Multiple anti-slip textures are provided on the outer sidewall of the toggle block. When the angle of the recognition head needs to be adjusted, the toggle block is pulled outward, and the connecting posts drive the gear to slide along the outer sidewall of the rectangular block, thereby disengaging the gear from the tooth groove. At this time, the recognition head and the connecting plate can rotate. The toggle block can be rotated to drive the gear to rotate, thereby causing the rotating shaft to drive the recognition head to rotate, thus realizing the angle adjustment of the device. After the angle is adjusted, the toggle block is pushed to make the gear re-engage in the tooth groove, thereby limiting the recognition head.

[0016] Preferably, a limiting block is fixedly connected to the outer wall of the end of the rectangular block, which solves the technical problem of preventing the gear from detaching from the outer wall of the rectangular block.

[0017] Preferably, the end of the motor does not abut against the side wall of the connecting plate to prevent the motor from abutting against the connecting plate during the rotation of the recognition head. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4As shown, a barcode reading device with a protective structure includes a reading head 1 and a support 2. A connecting plate 3 is symmetrically fixedly connected to the side wall of the support 2. A rotating shaft 17 is fixedly connected to both side walls of the reading head 1, and the ends of the rotating shaft 17 are rotatably connected to the side wall of the connecting plate 3. A movable plate 4 is slidably connected to the outer front wall of the reading head 1, and a cleaning brush 5 is fixedly connected to the side wall of the movable plate 4. A rectangular groove 10 is symmetrically formed on the outer front wall of the reading head 1. A sliding assembly is provided on the inner side wall of the rectangular groove 10. The sliding assembly includes a reciprocating screw 12 that passes through and is rotatably connected to the inner side wall of the rectangular groove 10. A slider 9 is threadedly connected to the outer side wall of the reciprocating screw 12, and the slider 9 is slidably connected to the inner side wall of the rectangular groove 10. The ends of the two sliders 9 are connected to the movable plate. The two ends of 4 are fixedly connected. During the rotation of the reciprocating screw 12, the slider 9 slides back and forth along the outer wall of the reciprocating screw 12. As the slider 9 moves along the outer wall of the reciprocating screw 12, it drives the moving plate 4 to move, thereby using the cleaning brush 5 to clean the dust at the end of the recognition head 1, preventing dust from blocking the lens and causing the technical problem of not being able to read the barcode. The side wall of the recognition head 1 is provided with a power component, which includes a motor 14 fixedly connected to the side wall of the recognition head 1. The side wall of the recognition head 1 is symmetrically rotatably connected with transmission wheels 13. The two transmission wheels 13 are respectively fixedly connected to the ends of the two reciprocating screws 12. The outer walls of the two transmission wheels 13 are fitted with belts 11. The output end of the motor 14 The outer wall of one of the transmission wheels 13 is fixedly connected. When dust needs to be cleaned from the end of the recognition head 1, the motor 14 is started, which drives one of the transmission wheels 13 to rotate. During the rotation of one transmission wheel 13, the belt 11 drives the other transmission wheel 13 to rotate, thereby driving the two reciprocating screws 12 to rotate through the two rotating transmission wheels 13, achieving the purpose of rotating the two reciprocating screws 12 simultaneously. The outer wall of the connecting plate 3 is provided with a toothed groove 18, and the inner wall of the toothed groove 18 is provided with a limit component. The limit component includes a gear 6 movably connected to the inner wall of the toothed groove 18. A rectangular block 16 is fixedly connected to the end of the rotating shaft 17, and the rectangular block 16 is slidably connected to the gear 6. The outer side of the gear 6 Multiple connecting posts 7 are fixedly connected to the wall, and a toggle block 8 is fixedly connected to the end of the connecting post 7. The outer wall of the toggle block 8 is provided with multiple anti-slip textures. When it is necessary to adjust the angle of the recognition head 1, by pulling the toggle block 8 outward, the connecting post 7 drives the gear 6 to slide along the outer wall of the rectangular block 16, thereby causing the gear 6 to disengage from the tooth groove 18. At this time, the recognition head 1 and the connecting plate 3 can rotate. By rotating the toggle block 8, the gear 6 drives the rectangular block 16 to rotate, thereby causing the rotating shaft 17 to drive the recognition head 1 to rotate, realizing the angle adjustment of this device. After the angle is adjusted, by pushing the toggle block 8, the gear 6 is re-engaged into the tooth groove 18, thus realizing the limiting work of the recognition head 1.

[0025] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0026] When this device is in use, and dust needs to be cleaned from the end of the recognition head 1, the motor 14 is started. The motor 14 drives one of the transmission wheels 13 to rotate. During the rotation of one transmission wheel 13, the belt 11 drives the other transmission wheel 13 to rotate. In turn, the two rotating transmission wheels 13 drive the two reciprocating screws 12 to rotate. During the rotation of the reciprocating screws 12, the slider 9 slides back and forth along the outer wall of the reciprocating screw 12. As the slider 9 moves along the outer wall of the reciprocating screw 12, it drives the moving plate 4 to move, thereby using the cleaning brush 5 to clean the dust from the end of the recognition head 1 and prevent the dust from obstructing the lens. The technical problem that prevents barcode reading is addressed by adjusting the angle of the recognition head 1. By pulling the actuating block 8 outward, the connecting column 7 drives the gear 6 to slide along the outer wall of the rectangular block 16, causing the gear 6 to disengage from the tooth groove 18. At this point, the recognition head 1 and the connecting plate 3 can rotate. By rotating the actuating block 8, the gear 6 drives the rectangular block 16 to rotate, which in turn causes the rotating shaft 17 to rotate the recognition head 1, thus achieving the angle adjustment of the device. After the angle adjustment is completed, by pushing the actuating block 8, the gear 6 is re-engaged into the tooth groove 18, thus limiting the position of the recognition head 1.
