Description

Technical Field

[0001] This application relates to the field of scanning equipment technology, and more specifically to a barcode scanner. Background Technology

[0002] As a highly efficient information collection tool, the core function of a barcode scanner is to identify barcodes or QR codes through optical principles. Barcodes and QR codes are carriers of product information, converting information such as product type, price, and origin into graphic symbols through different encoding methods. The scanner illuminates these symbols by emitting a light source (such as laser or LED light) and receives the reflected light signals, thereby deciphering the information within. This allows for the rapid and accurate capture and identification of the graphic features of barcodes or QR codes, and the automatic acquisition of product price information for convenient pricing. The button is a core interactive component on the scanner, and its design and function directly affect its ease of use and work efficiency. The button's main function is to initiate the scanning operation. When the user presses the button, the scanner activates its scanning module, emits a light source, and begins scanning the barcode or QR code. When the user releases the button, the scan is complete, and the scanner automatically transmits the identified information to the connected device. To ensure user comfort and convenience during prolonged use, buttons are typically located on the handle of the barcode scanner, allowing users to press them with their index finger while holding the device with one hand. For example, Chinese utility model patent CN204440414U discloses a fixed-position barcode scanner, comprising a scanning screen, scanner body, data cable, handle, mounting platform, scanning button, and mounting base. The mounting base is cylindrical and installed at the lower end of the handle. The mounting base works in conjunction with the mounting platform to ensure the scanner is fixed in place. The barcode scanning screen is located on the front face of the scanner body, relying on the light emitted and received by the scanning screen to identify the barcode on the product label. An elliptical cylindrical handle is connected to the lower end of the scanner body. In the aforementioned prior art, a scanning button is designed at the position where the operator holds the inner side of the handle with their index finger. When the scanning button is pressed, the scanning screen operates; when the index finger stops pressing the scanning button, it automatically returns to the off state. In traditional barcode scanners, the scan button is usually tightly integrated with the handle, employing a one-piece design. Replacing a damaged button often requires disassembling the entire device, which necessitates the use of specific tools. This process is not only time-consuming and labor-intensive but can also potentially damage other components due to improper handling. Therefore, there is an urgent need for a barcode scanner that allows for quick and easy removal and installation of the scan button. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a barcode scanner with a spring-loaded latch on the scanning button and a latch on the mounting part. Through the cooperation of the spring-loaded latch and the latch, the user can quickly disassemble and assemble the barcode scanner by applying force to the spring-loaded latch, which is labor-saving and efficient.

[0004] This application provides a barcode scanner, including a housing and a scanning button. The housing has a mounting portion adapted to the scanning button, and the scanning button has an elastic latch. The mounting portion has a latch adapted to the elastic latch. The elastic latch is connected to the latch to lock the scanning button to the mounting portion. When the elastic latch is subjected to force, it disengages from the latch through elastic deformation to unlock the scanning button from the mounting portion.

[0005] In this technical solution, the shape and size of the mounting part are adapted to the scanning button, forming an installation positioning benchmark. This allows the scanning button to be accurately installed in the preset position on the housing. An elastic latch is provided on the scanning button, and a locking position is provided on the mounting part. Through the cooperation of the elastic latch and the locking position, the connection between the scanning button and the mounting part is locked, ensuring that the scanning button is securely installed on the housing under normal working conditions, preventing it from easily loosening or falling off. When subjected to force, the elastic latch can disengage from the locking position through its own elastic deformation, thus unlocking the connection between the scanning button and the mounting part. The unlocking method is simple and direct, requiring no additional complex structures or tools. Quick disassembly can be achieved simply by applying appropriate external force to the scanning button, saving installation time and effort and improving the efficiency of scanning button assembly and disassembly. The scanning button can be disassembled separately for maintenance or replacement without disassembling the entire device, reducing equipment maintenance costs and minimizing the risk of damage to other components during maintenance, thereby improving the reliability and service life of the entire barcode scanner.

[0006] As an improvement, the elastic latch is equipped with a rotating shaft, which is rotatably connected to the latch position, allowing the scan button to rotate back and forth relative to the mounting part. In this technical solution, a rotating shaft is provided on the elastic latch, and the rotating shaft is rotatably connected to the latch position. When the scan button is subjected to external pressure, it can rotate around the rotating shaft. This rotation is key to triggering the scanning function; that is, when the scan button is pressed, it triggers the scanning function through rotation. The rotating shaft makes the triggering action of the scan button faster, reduces operation delay, and improves scanning efficiency. The added rotating shaft allows the scan button to not only be installed inside the housing but also to be triggered by rotation, reducing the number of parts, lowering production costs, and simplifying assembly.

[0007] As an improvement, the elastic latch is provided with a connecting seat, and the scanning button is provided with a clearance portion adapted to the connecting seat. The connecting seat has space for elastic deformation through the clearance portion. In this technical solution, the connecting seat is the key component connecting the elastic latch and the scanning button, playing a supporting and force-transmitting role. The clearance portion is a reserved space structure that provides space for the elastic deformation of the connecting seat. When the scanning button is subjected to external force, the scanning button can undergo elastic deformation within the clearance portion through the connecting seat, thereby disengaging from the latch and unlocking. The scanning button can be detached from the mounting part. The design of the clearance portion makes the overall structure of the scanning button simpler and more reliable.

[0008] As an improvement, the rotating shaft, connecting seat, and scanning button are all integrally molded structures. In this technical solution, the rotating shaft, connecting seat, and scanning button are manufactured through a one-time molding process, rather than being assembled from multiple independent parts. The integrally molded structure has no connection gaps or splicing points, reducing the risk of reduced mechanical strength or failure due to connection points. The scanning button is a complete entity, with no possibility of relative movement or loosening between the various parts, ensuring operational stability and reliability. It can also withstand mechanical stress and external impacts during long-term use, reducing fatigue damage caused by frequent operation, extending the service life of the scanning button, and improving production efficiency.

[0009] As an improvement, the rotating shaft is provided with a first guide slope adapted to the snap-fit ​​position, and the rotating shaft is inserted into the snap-fit ​​position through the first guide slope. In this technical solution, the shape and angle of the first guide slope match the shape of the snap-fit ​​position, which is used to guide the rotating shaft to be smoothly inserted into the snap-fit ​​position, ensuring that the rotating shaft can be smoothly engaged with the snap-fit ​​position, making the installation more accurate and reliable. The design of the first guide slope makes the insertion action smoother, reduces the resistance or jamming that may occur during the installation process, and improves the installation efficiency.

[0010] As an improvement, the latch is provided with a second guide ramp adapted to the elastic latch, and the elastic latch is inserted into the latch through the second guide ramp. In this technical solution, the shape and angle of the second guide ramp match the shape of the elastic latch, which guides the elastic latch to be smoothly inserted into the latch, ensuring that the elastic latch can smoothly engage with the latch, making the installation more accurate and reliable. The design of the second guide ramp makes the insertion action smoother, reducing possible resistance or jamming during installation and improving installation efficiency.

[0011] As an improvement, the mounting portion is provided with an opening, through which a portion of the scanning button protrudes from the housing. In this technical solution, the opening allows a portion of the scanning button to smoothly extend out of the housing. The shape and size of the opening are adapted to the protruding portion of the scanning button, ensuring that the scanning button can be stably installed inside the housing while allowing a portion of its structure to extend outside the housing. Users can easily locate and press the scanning button without opening the housing or performing complex operating procedures, thus improving user convenience.

[0012] As an improvement, the scan button is provided with a first blocking part adapted to the opening. The first blocking part abuts against the inner wall of the housing at the opening to limit the rotation range of the scan button. In this technical solution, the shape and size of the first blocking part are adapted to the opening, and it can make close contact with the inner wall of the housing at the opening. The main function of the first blocking part is to limit the rotation range of the scan button, prevent the button from being rotated excessively during use, and thus ensure the normal triggering of the scanning function.

[0013] As an improvement, the inner wall of the housing is provided with an inclined protrusion adapted to the first blocking part. The first blocking part has an inclined surface, and the first blocking part engages with the inclined protrusion through the inclined surface. In this technical solution, the inclined protrusion is a protruding structure with a certain slope. Its shape and angle are designed to engage with the inclined surface of the first blocking part. The design of the inclined protrusion and the inclined surface allows the scanning button to smoothly contact and disengage from the restriction range during rotation, reducing the mechanical impact of hard contact and extending the service life of the component.

[0014] As an improvement, two elastic latches are provided, symmetrically arranged on both sides of the scanning button, with two elastic latches corresponding to each latch position. In this technical solution, one elastic latch is provided on each side of the scanning button, and the two elastic latches are symmetrically distributed, making the force on the scanning button more even during installation and removal, reducing the risk of loosening or damage caused by uneven force on one side. Each elastic latch cooperates with a corresponding latch position to realize the dual locking and unlocking function of the scanning button, significantly enhancing the locking effect of the scanning button and ensuring that it will not loosen or fall off due to external force during use.

[0025] like Figures 1 to 5 As shown, this application discloses a barcode scanner, including a housing 1 and a scanning button 2. The housing 1 has a mounting part 11 adapted to the scanning button 2. The shape and size of the mounting part 11 are adapted to the scanning button 2 to form a mounting positioning reference, enabling the scanning button 2 to be accurately installed in a preset position on the housing 1. The scanning button 2 has an elastic latch 21, and the mounting part 11 has a latching position 12 adapted to the elastic latch 21. The elastic latch 21 is connected to the latching position 12 to lock the scanning button 2 to the mounting part 11. When the elastic latch 21 is subjected to force, it disengages from the latching position 12 through elastic deformation, thereby unlocking the scanning button 2 from the mounting part 11. By setting the elastic latch 21 on the scanning button 2 and the latching position 12 on the mounting part 11, the scanning button 2 can be unlocked through the mutual cooperation of the elastic latch 21 and the latching position 12. The connection and locking between the scanning button 2 and the mounting part 11 ensures that the scanning button 2 can be securely installed on the housing 1 under normal working conditions, preventing it from easily loosening or falling off. When the elastic latch 21 is subjected to force, it can disengage from the latch 12 through its own elastic deformation, thereby unlocking the connection between the scanning button 2 and the mounting part 11. The unlocking method is simple and direct, requiring no additional complex structures or tools. It can be quickly disassembled simply by applying appropriate external force to the scanning button 2, saving installation time and effort and improving the efficiency of disassembling and assembling the scanning button 2. The scanning button 2 can be disassembled separately for maintenance or replacement without disassembling the entire device, which not only reduces equipment maintenance costs but also reduces the risk of damage to other components that may occur during maintenance, thereby improving the reliability and service life of the entire barcode scanner.

[0026] More specifically, such as Figures 1 to 3As shown, the elastic latch 21 is provided with a rotating shaft 211, which is rotatably connected to the latch 12 so that the scan button 2 can rotate back and forth relative to the mounting part 11. The rotating shaft 211 is provided on the elastic latch 21, and the rotating shaft 211 is rotatably connected to the latch 12. When the scan button 2 is subjected to external pressing force, it can rotate around the rotating shaft 211. The rotation action is the key to triggering the scanning function. That is, when the scan button 2 is pressed, the scan button 2 triggers the scanning function by rotating. The setting of the rotating shaft 211 makes the triggering action of the scan button 2 faster, reduces the operation delay, and improves the scanning efficiency. The added rotating shaft 211 allows the scan button 2 to not only be installed in the housing 1, but also to realize the rotation triggering of the scan button 2, reducing the number of parts, reducing production costs and assembly difficulty.

[0027] More specifically, such as Figure 2 As shown, the elastic latch 21 is provided with a connecting seat 212, and the scanning button 2 is provided with a clearance portion 22 adapted to the connecting seat 212. The connecting seat 212 has space for elastic deformation through the clearance portion 22. The connecting seat 212 is a key component connecting the elastic latch 21 and the scanning button 2, playing a supporting and force-transmitting role. The clearance portion 22 is a reserved space structure that provides space for the elastic deformation of the connecting seat 212. When the scanning button 2 is subjected to external force, the scanning button 2 can undergo elastic deformation in the clearance portion 22 through the connecting seat 212, thereby disengaging from the latch 12 to unlock. The scanning button 2 can be detached from the mounting part 11. The design of the clearance portion 22 makes the overall structure of the scanning button 2 simpler and more reliable.

[0028] More specifically, such as Figure 2 As shown, the rotating shaft 211, connecting seat 212, and scanning button 2 are all integrally molded structures. The rotating shaft 211, connecting seat 212, and scanning button 2 are manufactured through a one-time molding process, rather than being assembled from multiple independent parts. The integrally molded structure has no connection gaps or splicing points, reducing the risk of reduced mechanical strength or failure due to connection parts. The scanning button 2 is a complete entity, and there is no possibility of relative movement or loosening between the various parts, ensuring the stability and reliability of operation. It can also withstand mechanical stress and external impact during long-term use, reducing fatigue damage caused by frequent operation, extending the service life of the scanning button 2, and improving production efficiency.

[0029] More specifically, such as Figure 2As shown, the rotating shaft 211 is provided with a first guide slope 213 that is adapted to the buckle 12. The rotating shaft 211 is inserted into the buckle 12 through the first guide slope 213. The shape and angle of the first guide slope 213 are matched with the shape of the buckle 12 to guide the rotating shaft 211 to be smoothly inserted into the buckle 12, ensuring that the rotating shaft 211 can be smoothly engaged with the buckle 12, making the installation more accurate and reliable. The design of the first guide slope 213 makes the insertion action smoother, reduces the resistance or jamming that may occur during the installation process, and improves the installation efficiency.

[0030] More specifically, such as Figure 4 As shown, the buckle 12 is provided with a second guide slope 121 adapted to the elastic buckle 21. The elastic buckle 21 is inserted into the buckle 12 through the second guide slope 121. The shape and angle of the second guide slope 121 are matched with the shape of the elastic buckle 21, which is used to guide the elastic buckle 21 to be smoothly inserted into the buckle 12, ensuring that the elastic buckle 21 can be smoothly engaged with the buckle 12, making the installation more accurate and reliable. The design of the second guide slope 121 makes the insertion action smoother, reduces the resistance or jamming that may occur during the installation process, and improves the installation efficiency.

[0031] More specifically, such as Figure 3 As shown, the mounting part 11 is provided with an opening 13. A portion of the scanning button 2 extends out of the housing 1 through the opening 13. The opening 13 is used to allow a portion of the scanning button 2 to extend smoothly out of the housing 1. The shape and size of the opening 13 are adapted to the extended portion of the scanning button 2, which ensures that the scanning button 2 can be stably installed inside the housing 1, while allowing part of its structure to extend out of the housing 1. Users can easily find and press the scanning button 2 without opening the housing 1 or performing complicated operating steps, thus improving the convenience of user operation.

[0032] More specifically, such as Figure 2 As shown, the scan button 2 is provided with a first blocking part 23 adapted to the opening 13. The first blocking part 23 abuts against the inner wall of the housing 1 at the opening 13 to limit the rotation range of the scan button 2. The shape and size of the first blocking part 23 are adapted to the opening 13 and can be in close contact with the inner wall of the housing 1 at the opening 13. The main function of the first blocking part 23 is to limit the rotation range of the scan button 2 and prevent the button from being rotated excessively during use, thereby ensuring the normal triggering of the scanning function.

[0033] More specifically, such as Figure 5As shown, the inner wall of the housing 1 is provided with an inclined protrusion 14 adapted to the first blocking part 23.

The design of the inclined protrusion 14 and the inclined surface allows the scanning button 2 to smoothly contact and disengage from the restriction range during rotation, reducing the mechanical impact of hard contact and extending the service life of the component.

[0034] More specifically, such as Figure 2 As shown, there are two elastic latches 21, which are symmetrically arranged on both sides of the scanning button 2. There are two corresponding elastic latches 21 on each side of the locking position 12. The two elastic latches 21 are symmetrically distributed, which makes the force on the scanning button 2 more even during installation and removal, reducing the risk of loosening or damage caused by uneven force on one side. Each elastic latch 21 cooperates with the corresponding locking position 12 to realize the dual locking and unlocking function of the scanning button 2, which significantly enhances the locking effect of the scanning button 2 and ensures that it will not loosen or fall off due to external force during use.
