[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. 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.

[0016] Please see Figures 1-4 As shown, a portable prize redemption barcode scanner includes a prize redemption barcode scanner housing 1, a prize redemption barcode scanner body 2 is snapped into the housing 1, a functional mechanism is assembled inside the body 2, and a portable handle 3 is assembled at the bottom of the housing 1; a swing cavity 8 is formed on the rear side wall of the housing 1, and swing holes 10 are formed on both sides of the inner wall of the swing cavity 8; a swing head 12 is assembled at the top of the portable handle 3, and swing holes 10 are installed on both sides of the outer wall of the swing head 12. The movable shaft 13 and the swing shaft 13 are installed inside the swing hole 10. The outer end of the swing shaft 13 near the swing head 12 is fitted with a sealing gasket 14. The swing shaft 13 and the swing hole 10 are interference fit. The rear side wall of the prize redemption scanning machine housing 1 is provided with a storage cavity 9 located below the swing cavity 8. The portable handle 3 is installed in the storage cavity 9. The outer wall of the swing head 12 is provided with a smooth surface 17. The outer wall of the portable handle 3 is engaged with the inner wall of the storage cavity 9 by a snap-fit ​​mechanism.

[0017] In the specific implementation process, the prize redemption scanning machine housing 1, as the external protection and installation carrier of the equipment, is made of high-strength engineering plastic in one piece, possessing lightweight and impact-resistant characteristics. It can effectively protect the internal prize redemption scanning machine body 2 from collision and squeezing damage. The prize redemption scanning machine body 2 is fixed inside the housing by a snap-fit ​​method, which is convenient for disassembly and assembly, and facilitates later maintenance and functional module upgrades. The portable handle 3 is the core portable component. Its top swing head 12 is adapted to the swing cavity 8 on the rear side wall of the housing. The swing shafts 13 on the left and right sides are precisely embedded in the swing holes 10, forming a rotatable connection structure to realize the angle adjustment function of the handle. The sealing gasket 14 on the outside of the swing shaft 13 is made of silicone rubber, which fits tightly against the swing shaft 13 and the swing hole 10. The 0mm gap effectively prevents dust, moisture, and other impurities from entering the casing, avoiding corrosion of internal circuits and functional modules. The swing shaft 13 and swing hole 10 adopt an interference fit design with a tolerance controlled between 0.02-0.05mm, ensuring smooth swinging of the handle and preventing loosening or shaking after long-term use. The smooth surface 17 of the outer wall of the swing head 12 is polished to reduce frictional resistance between the swing head and the inner wall of the swing cavity 8, improving the operating feel and extending the service life of the structure. The size of the storage cavity 9 is precisely matched with the shape of the portable handle 3. When the handle is fully stored, the outer wall fits tightly with the inner wall of the storage cavity, which can significantly reduce the overall size of the device and make it easy to carry in a backpack, toolbox, or other carrier.

[0018] In some technical solutions, the locking mechanism includes a locking block 18 installed at the bottom of the storage cavity 9 and a locking slot 19 opened on the outer wall of the portable grip 3, with the locking block 18 and the locking slot 19 cooperating with each other.

[0019] In the specific implementation process, the locking mechanism is the key structure for the storage and fixation of the portable grip 3. The locking block 18 at the bottom of the storage cavity 9 is made of hard elastic plastic, which has a certain degree of toughness and wear resistance. The slot 19 is opened at the corresponding position on the outer wall of the portable grip 3. Its depth and width are perfectly matched with the size of the locking block 18. When the portable grip 3 is stored in the storage cavity 9, the locking block 18 is precisely embedded in the slot 19. The mechanical locking action restricts the displacement of the grip, ensuring that the grip will not fall out on its own during the carrying of the device, thus improving the structural stability. The cooperation design of the locking block and the slot does not require additional locking parts. It achieves fixation by its own structure, which simplifies the operation process. Users only need to press the grip lightly to complete the storage and fixation, and apply force in the opposite direction to release and unfold it, which is highly convenient.

[0020] In some technical solutions, the outer walls on both sides of the card block 18 are provided with inclined convex surfaces 23, and the inner walls on both sides of the card slot 19 are provided with inclined concave surfaces 24, with the inclined convex surfaces 23 and the inclined concave surfaces 24 cooperating with each other.

[0021] In practical implementation, the convex surfaces 23 on both sides of the outer wall of the locking block 18 and the concave surfaces 24 on both sides of the inner wall of the slot 19 are complementary bevel designs. This angle design ensures both the guiding effect during locking and provides sufficient locking force. When the handle is stored, the convex surfaces 23 and concave surfaces 24 slide against each other, guiding the locking block 18 smoothly into the slot 19 through the guiding effect of the bevels, avoiding jamming. After locking, the contact surfaces between the bevels form a lateral support force, preventing the handle from loosening in the horizontal direction, further improving the structural stability after storage. Compared with vertical surface mating, the bevel design can disperse the force during locking, reduce local wear, and extend the service life of the locking mechanism.

[0022] In some technical solutions, the card block 18 has a filling cavity 20 inside, an elastic element 21 is installed inside the filling cavity 20, and the end of the card block 18 is provided with an arc surface 22.

[0023] In the specific implementation process, the filling cavity 20 inside the locking block 18 is a cylindrical cavity, the inner diameter of which matches the outer diameter of the elastic element 21. The elastic element 21 is preferably a cylindrical helical spring, which has good elastic restoring performance. When the grip is stored, the locking block 18 is squeezed by the locking groove 19, and the elastic element 21 is compressed and deformed in the filling cavity 20, generating a reverse elastic force, so that the locking block 18 tightly abuts against the inner wall of the locking groove, enhancing the locking firmness. When it is necessary to unfold the grip, the elastic element 21 is reset under the action of external force, pushing the locking block 18 smoothly out of the locking groove, avoiding the inconvenience caused by excessive locking. The radius of the arc surface 22 at the end of the locking block 18 is set to 3mm, adopting an arc transition design, which can effectively reduce the pressure when the locking block contacts the locking groove, avoid wear on the inner wall of the locking groove caused by sharp edges, and further optimize the smoothness of the locking and unlocking process, improving the user's operating experience.

[0024] In some technical solutions, the side wall of the portable grip 3 is provided with a grip opening 15, and the inner wall of the grip opening 15 is provided with an anti-slip surface 16.

[0025] In practical implementation, the grip opening 15 on the side wall of the portable grip 3 adopts a U-shaped structure design, with the opening width adapted to the thickness of the fingers, facilitating finger insertion and improving the stability of the grip. The anti-slip surface 16 on the inner wall of the grip opening 15 is made of rubber through secondary injection molding, and the surface has anti-slip texture, which can significantly increase the friction coefficient between the palm and the grip, effectively preventing slippage when hands are wet, sweaty, or when gripping for a long time, reducing the risk of dropping the device. At the same time, the rubber anti-slip surface has a certain degree of softness, which can cushion the pressure when gripping, improve the comfort of long-term operation, and meet the needs of high-frequency prize redemption scenarios outdoors.

[0026] In some technical solutions, a display screen slot 5 is provided on the front top of the prize redemption scanning machine housing 1, a button slot 6 is provided on the rear top of the prize redemption scanning machine housing 1, a scanning port slot 4 is provided on the front end of the prize redemption scanning machine housing 1, a protective block 7 is installed at the bottom of the prize redemption scanning machine housing 1, and heat sinks 11 are installed on both side walls of the prize redemption scanning machine housing 1.

[0027] In the specific implementation process, the display screen slot 5 on the front top of the prize redemption scanning machine casing 1 is precisely matched with the display screen. The edge of the slot is equipped with a buffer rubber ring to prevent the display screen from colliding with the slot wall after installation, and at the same time, it plays a role in sealing and dust prevention. The button slot 6 on the rear top is used to accommodate operation buttons such as the confirm button, cancel button, and scan button. The scanning port slot 4 at the front of the casing corresponds to the scanning head of the internal scanning and recognition module. The slot is encapsulated with transparent acrylic material, which does not affect the transmission of scanning light and protects the scanning head from dust and collision damage. The protective blocks 7 at the bottom of the casing are made of wear-resistant rubber material and are distributed at the four corners of the casing. When the device is accidentally dropped, it can buffer the impact force and prevent the casing and the internal body from directly contacting the ground, reducing the risk of damage. The heat sinks 11 on both sides of the casing are made of aluminum alloy and are fixed to the outer wall of the casing with screws. They correspond to the heat dissipation areas of the internal functional modules. The aluminum alloy material has excellent thermal conductivity and can quickly conduct the heat generated by the internal modules to the outside, avoiding heat accumulation that could cause the equipment to malfunction or crash, and ensuring the stability of the equipment during long-term continuous operation.

[0028] In some technical solutions, the functional components include a barcode scanning and identification module, a communication transmission module, a human-computer interaction module, a business logic module, and a security and support module.

[0029] In practical implementation, the five modules of the functional structure are the core working units of the equipment. Each module works together to realize the full-process function of prize redemption scanning: the scanning and recognition module integrates an industrial-grade image scanning engine and image processing unit, which can quickly recognize various code types such as 1D and 2D codes, and is compatible with different carriers such as paper codes and screen codes. Even if the code is dirty or tilted, it can still be accurately decoded; the communication transmission module supports multiple wireless communication methods such as 4G / 5G, Wi-Fi, and Bluetooth, which can realize real-time data interaction between the device and the back-end prize redemption system and payment platform. It also has an offline storage function, which can temporarily store scanning data when the network is disconnected and automatically upload it when the network is connected; the human-machine interaction module uses the touch screen in the display slot 5. The device features bidirectional interaction with the operation buttons within button slot 6. The touchscreen displays scanning results, prize redemption information, and device status, while the operation buttons allow users to quickly execute commands such as scanning, confirming, and canceling. The business logic module incorporates a prize redemption rule algorithm, enabling core business processes such as ticket validity verification, anti-duplicate prize redemption, prize amount calculation, and fund disbursement triggering, ensuring compliant and efficient prize redemption operations. The security and support module integrates a financial-grade security chip, an encrypted storage unit, and a power management unit. This ensures encrypted transmission and storage of prize redemption data, preventing information leakage, and provides extended battery life through high-performance batteries and power optimization technology, supporting the needs of outdoor mobile prize redemption scenarios.
