Description

Technical Field

[0001] This utility model relates to the field of handheld barcode scanner technology, and in particular to a protective cover for preventing accidental touches on a handheld barcode scanner. Background Technology

[0002] Handheld barcode scanners play a crucial role in the efficient operation of modern logistics warehousing and manufacturing. In warehousing and handling, workers frequently use scanners to scan barcodes on goods to accurately record their entry and exit information. On production lines, scanners are used for quality traceability and process control of components and products. However, current handheld barcode scanners suffer from serious accidental touches during practical use.

[0003] Due to the specific nature of their use cases, operators often need to hold the scanner for extended periods during busy work. Even when not in use, the scanner remains in a state of constant potential operation. During this time, the operator's palm holding the scanner can easily press against the function keys, triggering accidental operations. These accidents might manifest as accidentally activating the scanning function, leading to the system collecting incorrect data; or incorrectly switching modes, preventing the scanner from operating in the correct mode. These problems not only significantly increase the error rate of data acquisition but also potentially affect the accuracy and efficiency of the entire workflow, increase the cost of manual error correction, and may even trigger a series of problems in subsequent stages. Therefore, we propose a handheld barcode scanner anti-accidental touch protective cover to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a protective cover for handheld barcode scanners to prevent accidental touches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A protective cover for a handheld barcode scanner to prevent accidental touches includes a handle, a scanning head mounted on the upper end of the handle, a scanning screen on one side of the scanning head, a protective cover body mounted on one side of the handle, a threaded sleeve rotatably fitted onto one side of the protective cover body, a rotating block fixed to one end of the threaded sleeve, a pushing mechanism connected to one end of the threaded sleeve, a connecting rod connected to one end of the pushing mechanism via a linkage structure, the connecting rod rotatably connected to one side of the protective cover body via a positioning shaft, a support rail rotatably connected to the upper end of the connecting rod, a snap-fit ​​mechanism connected to the upper end of the support rail, a button mounted on the handle, the snap-fit ​​mechanism corresponding to the button, and a sealing strip installed at the connection between the protective cover body and the handle.

[0006] Preferably, the pushing mechanism includes a stud threaded to one end of a threaded sleeve, and a movable block is fixed to one end of the stud.

[0007] Preferably, the linkage structure includes a rotating rod rotatably connected to one side of the moving block, with one end of the rotating rod rotatably connected to one end of the connecting rod.

[0008] Preferably, one end of the connecting rod is rotatably connected to a T-shaped slider, the lower end of the support rail is provided with a T-shaped groove, and the T-shaped slider is installed on the T-shaped groove.

[0009] Preferably, one end of the button is connected to a spring, and one end of the spring is connected to a stop block, the stop block having two snap-fit ​​holes.

[0010] Preferably, the locking mechanism includes two limiting rods fixed to the upper end of the support rail, and the two limiting rods pass through two locking holes.

[0011] In this utility model: 1. Initial state: When the handheld barcode scanner is in normal use, the protective case is unlocked, the buttons can be operated normally, and the scanning screen and scanning head can freely complete the scanning task; 2. Anti-accidental start: When the operator is not using the scanner temporarily, rotating the rotating block will cause the threaded sleeve fixedly connected to it to rotate synchronously. 3. Pushing mechanism action: Since the stud is screwed to the threaded sleeve, the rotation of the threaded sleeve will cause the stud to move along the thread direction towards the moving block. The movement of the stud will drive the moving block fixed to it to move together. 4. Linkage structure response: The movement of the moving block drives the rotating rod to move. One end of the rotating rod is rotatably connected to the moving block, and the other end is rotatably connected to one end of the connecting rod. The movement of the rotating rod causes the lower end of the connecting rod to rotate around the positioning shaft. Due to the limiting effect of the positioning shaft on the connecting rod, the upper end of the connecting rod will rise. 5. Snap-fit ​​mechanism operation: When the upper end of the connecting rod rises, the support rail that is rotatably connected to it also rises. The two limit rods fixed at the upper end of the support rail will move upward and eventually pass through the two snap-fit ​​holes on the contact block to lock the button and prevent accidental activation. 6. Deactivate the anti-accidental touch function: When the scanner needs to be used again, rotate the rotating block in the opposite direction to reverse the above process. The limit rod will retract from the locking hole, and the button will return to the operable state.

[0012] This utility model has the following advantages: 1. The buttons can be locked by rotating the rotating block, which effectively avoids accidental touches of function keys by the operator's palm when holding the scanner, greatly reducing the error rate of data acquisition and improving the accuracy of work data; 2. The anti-accidental touch function can be turned on and off with just a simple action of rotating the rotating block, without complicated operation steps, making it convenient for operators to use; 3. The mechanical linkage structure composed of components such as threaded sleeves, studs, rotating rods, and connecting rods has high reliability, low cost, and high practical value. In summary, this invention effectively avoids accidental touches of function keys by operators' palms when holding the scanner, greatly reducing the error rate of data acquisition, improving the accuracy of operational data, reducing data errors caused by misoperation and subsequent manual error correction work, making warehousing, handling and production line operations smoother, and improving overall work efficiency.

Detailed Implementation

[0015] 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.

[0016] Reference Figure 1-5 A protective cover for a handheld barcode scanner to prevent accidental touch includes a handle 6, a scanning head 2 installed at the upper end of the handle 6, and a scanning screen 1 on one side of the scanning head 2. The scanning head 2 is the core component for scanning barcodes. The scanning screen 1 is used to display the scanned barcode information and related operation prompts. The scanning screen 1 has the characteristics of high resolution and fast response, and can clearly and accurately display barcode data, providing intuitive feedback to the operator. A protective cover body 5 is installed on one side of the grip 6. A threaded sleeve 18 is rotatably sleeved on one side of the protective cover body 5. A rotating block 4 is fixed to one end of the threaded sleeve 18. A pushing mechanism is connected to one end of the threaded sleeve 18. A connecting rod 14 is connected to one end of the pushing mechanism through a linkage structure. The connecting rod 14 is rotatably connected to one side of the protective cover body 5 through a positioning shaft 20. A support rail 19 is rotatably connected to the upper end of the connecting rod 14. A snap-fit ​​mechanism is connected to the upper end of the support rail 19. A button 3 is installed on the grip 6. The snap-fit ​​mechanism corresponds to the button 3. During normal use, the protective cover body 5 will not interfere with the operation of the scanner. Instead, it plays a certain protective role to prevent the scanner from being accidentally bumped. The pushing mechanism includes a stud 16 threaded to one end of a threaded sleeve 18. A moving block 17 is fixed to one end of the stud 16. When the threaded sleeve 18 rotates, the stud 16 will move along the thread direction due to the thread engagement, thereby driving the moving block 17 to move. The threaded connection between the stud 16 and the threaded sleeve 18 has high precision, which can ensure the stability and accuracy of the movement and avoid jamming or shaking. The linkage structure includes a rotating rod 15 rotatably connected to one side of the moving block 17. One end of the rotating rod 15 is rotatably connected to one end of the connecting rod 14. When the moving block 17 moves, the rotating rod 15 will change its angle as the moving block 17 moves, thereby pushing the connecting rod 14 to rotate around the positioning shaft 20. One end of the connecting rod 14 is rotatably connected to a T-shaped slider 13, and the lower end of the support rail 19 is provided with a T-shaped groove 12. The T-shaped slider 13 is installed on the T-shaped groove 12. The T-shaped slider 13 and the T-shaped groove 12 fit tightly, so that when the connecting rod 14 rotates, it can drive the support rail 19 to rise or fall smoothly. One end of button 3 is connected to spring 8, and the other end of spring 8 is connected to a stop block 9. The stop block 9 has two snap-fit ​​holes 10. Spring 8 provides elastic force for button 3 to reset. When button 3 is pressed, spring 8 will cause button 3 to return to its initial position. The stop block 9 touches the electrical components of the control switch and sends a command. The locking mechanism includes two limiting rods 11 fixed to the upper end of the support rail 19. The two limiting rods 11 pass through two locking holes 10. When the support rail 19 rises, the limiting rods 11 will be inserted into the locking holes 10 to lock the button 3 and prevent accidental activation. When the support rail 19 falls, the limiting rods 11 will be removed from the locking holes 10 and the button 3 will return to the operable state.

[0017] In this utility model: 1. Initial state: When the handheld barcode scanner is in normal use, the protective cover is in the unlocked state, button 3 can be operated normally, and scanning screen 1 and scanning head 2 can freely complete the scanning task; 2. Anti-accidental start: When the operator is not using the scanner temporarily, rotating the rotating block 4 will cause the threaded sleeve 18 fixedly connected to it to rotate synchronously. 3. Pushing mechanism action: Since the stud 16 is screwed to the threaded sleeve 18, the rotation of the threaded sleeve 18 will cause the stud 16 to move along the thread direction towards the moving block 17. The movement of the stud 16 will drive the moving block 17 fixed to it to move together. 4. Linkage structure response: The movement of the moving block 17 pushes the rotating rod 15 to move. One end of the rotating rod 15 is rotatably connected to the moving block 17, and the other end is rotatably connected to one end of the connecting rod 14. The movement of the rotating rod 15 causes the lower end of the connecting rod 14 to rotate around the positioning shaft 20. Due to the limiting effect of the positioning shaft 20 on the connecting rod 14, the upper end of the connecting rod 14 will rise. 5. Snap-fit ​​mechanism operation: When the upper end of the connecting rod 14 rises, the support rail 19 rotatably connected to it also rises. The two limit rods 11 fixed at the upper end of the support rail 19 will move upward and eventually pass through the two snap-fit ​​holes 10 on the contact block 9 to lock the button 3 and prevent accidental activation. 6. Deactivate the anti-accidental touch function: When the scanner needs to be used again, rotate the rotating block 4 in the opposite direction. The above process will be reversed, the limit rod 11 will be disengaged from the snap-fit ​​hole 10, and the button 3 will be restored to the operable state.

[0018] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
