Description

Technical Field

[0001] This utility model relates to the technical field of barcode scanning devices, specifically a handheld portable barcode scanning device. Background Technology

[0002] A scanner is a device that uses photoelectric technology and digital processing technology to convert graphic or image information into digital signals through scanning. Barcode scanning devices are now widely used in various fields, including product information, payment and data registration. Currently, the most commonly used type is the handheld barcode scanner.

[0003] For example, patent CN212515816U discloses a handheld barcode scanning device with anti-escape function, including a chassis, a telescopic cylinder connected to the top of the chassis, and a telescopic rod connected inside the telescopic cylinder. The telescopic cylinder is connected to the telescopic rod through an adjusting bolt, and the telescopic rod passes through the top of the telescopic cylinder and connects to a support plate. The support plate has a connecting groove, and L-shaped connecting sleeves are provided on both sides of the connecting groove. A sliding rod is provided on the L-shaped connecting sleeve, and the sliding rod passes through the bottom of the L-shaped connecting sleeve and connects to a second spring. One end of the second spring is fixed to the inner wall of the connecting groove, and the other end of the second spring is connected to a pressing plate. A hand handle is connected inside the connecting groove, and L-shaped connecting plates are connected to both sides of the bottom end of the hand handle.

[0004] Through the above-described design, the existing handheld barcode scanning device with anti-slip function improves the connection between the fingers and the device by using upper and lower clamps on the handle, preventing slippage during operation. However, the existing handheld barcode scanning device has the following drawbacks during operation:

[0005] The aforementioned device is designed to place the base on top of the table and then place the scanning device inside the base for easy operation. However, this device simply places the base on the table, which causes instability in the center of gravity of the entire device after the scanning device is placed inside the base, resulting in the device falling over. Utility Model Content

[0006] This utility model aims to provide a handheld portable barcode scanning device, mainly to solve the technical problem that the chassis and telescopic cylinder do not have a reinforced structure, and the device body and table will tip over.

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

[0008] A handheld portable barcode scanning device includes a scanning device body and a fixed base. A suction cup is fixedly connected to the bottom of the fixed base. A fixed plate is fixedly connected to the inner wall of the upper end of the fixed base. A movable plate is slidably connected to the inner wall of the lower end of the fixed base. A piston is fixedly connected to the bottom of the movable plate. A rectangular groove is formed on the top of the movable plate. A lifting component is slidably connected to the inner wall of the rectangular groove. An adjustment component is rotatably connected through the outer wall of the fixed base. Reinforcing components are symmetrically fixedly connected to the outer wall of the fixed base.

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

[0010] 1. Working Principle: When using this device, first place the fixed base on the top of the table, then rotate the adjustment component. The adjustment component drives the lifting component to work. During the operation of the lifting component, the moving plate slides upward along the inner wall of the fixed base. As the moving plate slides upward, the piston draws air from inside the suction cup, thereby using the suction cup to install the fixed base on the top of the table. Then, the fixed base is reinforced by the reinforcement component. Finally, the scanning device body is inserted into the fixed base for easy use.

[0011] 2. Beneficial effects:

[0012] Existing technologies improve the connection between fingers and the device by using upper and lower clamps on the handle to avoid slippage during operation. However, these technologies lack reinforcement structures for the chassis and telescopic cylinder, leading to potential tipping of the device body against the tabletop. This solution addresses this issue by incorporating an adjustment component to facilitate the operation of the lifting component. This component causes the lifting plate to slide upwards along the inner wall of the fixed base. As the plate slides upwards, a piston extracts air from the suction cup, which then uses the suction cup to mount the fixed base onto the top of the tabletop, preventing collapse. Furthermore, the included reinforcement component allows for secondary reinforcement of the fixed base, ensuring stable placement even on uneven surfaces.

[0013] Preferably, the lifting assembly includes symmetrically slidably connected movable blocks on the inner wall of a rectangular slide groove. A second mounting base is fixedly connected to the top of each movable block. Connecting rods are rotatably connected to the inner walls of the two second mounting bases. First mounting bases are rotatably connected to the outer walls of the upper ends of the two connecting rods. In use, the fixed base is first placed on a table. Then, by rotating the adjustment assembly, the two first mounting bases move away from each other. During this movement, they rotate relative to the two connecting rods. As the two first mounting bases move away from each other, the angle between the two connecting rods increases, and the tilt angle of the two connecting rods gradually decreases. Under the action of the second mounting bases, the two movable blocks move away from each other, causing them to slide along the inner wall of the rectangular slide groove. This causes the movable plate to slide upwards along the inner wall of the fixed base. During the upward sliding of the movable plate, a piston extracts air from the suction cup, thereby using the suction cup to mount the fixed base on the top of the table, preventing the fixed base from tipping over.

[0014] Preferably, the adjustment assembly includes a bidirectional lead screw that passes through and is rotatably connected to the outer wall of the fixed base. The outer wall of the bidirectional lead screw is symmetrically threaded with sliders, and the top of the sliders is slidably connected to the bottom of the fixed plate. The bottoms of the two sliders are respectively fixedly connected to the tops of the two first mounting seats. When it is necessary to move the two first mounting seats away from each other, the bidirectional lead screw is rotated. During the rotation of the bidirectional lead screw, the two sliders move away from each other, thereby driving the two first mounting seats to move away from each other, achieving the purpose of quickly adjusting the moving plate upward.

[0015] Preferably, a lever block is fixedly connected to one end of the bidirectional lead screw located on the outer wall of the fixed base. When it is necessary to rotate the bidirectional lead screw, only the lever block needs to be rotated, thereby achieving the purpose of saving effort.

[0016] Preferably, the reinforcement component includes T-shaped rods symmetrically fixed to the outer wall of the mounting base. L-shaped legs are slidably connected to the inner walls of both ends of the T-shaped rods. When the mounting base is installed on the top of the desktop using a suction cup, the L-shaped legs are pulled outward to slide outward along the inner wall of the T-shaped rod, thereby fixing the mounting base again through the L-shaped legs. This achieves the technical problem of stable placement of the mounting base on uneven desktops.

[0017] Preferably, the reinforcement component further includes a screw threaded to the lower end of the L-shaped support leg. The lower end of the screw is fixedly connected to a base plate. When the tabletop is uneven, it is only necessary to rotate the screw to extend the length of the screw on the outside of the L-shaped support leg, so that the device can be placed and operated on uneven tabletop surfaces.

[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 handheld portable barcode scanning device includes a scanning device body 1 and a fixed base 2. A suction cup 8 is fixedly connected to the bottom of the fixed base 2. A fixed plate 9 is fixedly connected to the inner wall of the upper end of the fixed base 2. A movable plate 12 is slidably connected to the inner wall of the lower end of the fixed base 2. A piston 13 is fixedly connected to the bottom of the movable plate 12. A rectangular slide groove 11 is formed on the top of the movable plate 12. A lifting assembly is slidably connected to the inner wall of the rectangular slide groove 11. The lifting assembly includes movable blocks 18 symmetrically slidably connected to the inner wall of the rectangular slide groove 11. A second mounting base 17 is fixedly connected to the top of the movable blocks 18. Connecting rods 15 are rotatably connected to the inner walls of the two second mounting bases 17. The outer walls of the two connecting rods 15 at the upper end rotate. A first mounting base 16 is connected. As the two first mounting bases 16 move away from each other, they rotate relative to the two connecting rods 15. As the two first mounting bases 16 move away from each other, the included angle between the two connecting rods 15 increases, and the tilt angle of the two connecting rods 15 gradually decreases. Under the action of the second mounting base 17, the two moving blocks 18 move away from each other, causing the two moving blocks 18 to slide along the inner wall of the rectangular slide groove 11. This causes the moving plate 12 to slide upward along the inner wall of the fixed base 2. During the upward sliding of the moving plate 12, the piston 13 draws air from the suction cup 8, thereby using the suction cup 8 to mount the fixed base 2 on the top of the table, preventing the fixed base 2 from tipping over. An adjustment assembly is rotatably connected through the outer wall of the fixed base 2. The adjustment assembly includes a bidirectional lead screw 10 that is rotatably connected through the outer wall of the fixed base 2. Slider blocks 14 are symmetrically threaded onto the outer wall of the bidirectional lead screw 10, and the tops of the sliders 14 are slidably connected to the bottom of the fixed plate 9. The bottoms of the two sliders 14 are respectively fixedly connected to the tops of the two first mounting seats 16. A toggle block 5 is fixedly connected to one end of the bidirectional lead screw 10 located on the outer wall of the fixed base 2. In use, the fixed base 2 is first placed on the top of the table, and the toggle block 5 is rotated, causing the bidirectional lead screw 10 to rotate. During the rotation of the bidirectional lead screw 10, the two sliders 14 move away from each other, thereby driving the two first mounting seats 16 respectively. The mounting bases 16 are spaced apart to allow for quick upward adjustment of the movable plate 12. The outer walls of the fixed base 2 are symmetrically fixed with reinforcing components. These components include T-shaped rods 3 symmetrically fixed to the outer walls of the fixed base 2, with L-shaped legs 6 slidably connected to the inner walls of both ends of the T-shaped rods 3. The reinforcing components also include screws 7 threaded to the lower ends of the L-shaped legs 6, with a base plate 4 fixedly connected to the lower end of the screws 7. When the fixed base 2 is mounted on the top of the desktop using the suction cup 8, pulling the L-shaped legs 6 outwards causes them to slide outwards along the inner walls of the T-shaped rods 3, thus re-fixing the fixed base 2. This achieves the technical problem of stable placement of the fixed base 2 even on uneven desktops.When the tabletop is uneven, simply rotate screw 7 to extend its length beyond the L-shaped support leg 6, allowing the device to be placed and operated even on uneven surfaces. Finally, insert the scanning device body 1 into the mounting base 2 for convenient use.

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

[0026] In use, the fixed base 2 is first placed on the top of the table. The actuating block 5 is rotated, causing the bidirectional lead screw 10 to rotate. During the rotation of the bidirectional lead screw 10, the two sliders 14 move away from each other, thereby causing the two first mounting seats 16 to move away from each other. As the two first mounting seats 16 move away from each other, they rotate relative to the two connecting rods 15. As the two first mounting seats 16 move away from each other, the angle between the two connecting rods 15 increases, and the tilt angle of the two connecting rods 15 gradually decreases. Under the action of the second mounting base 17, the two moving blocks 18 move away from each other, causing the two moving blocks 18 to slide along the inner wall of the rectangular slide groove 11. This, in turn, causes the moving plate 12 to slide upwards along the inner wall of the fixed base 2. During the upward sliding of the movable plate 12, the piston 13 draws air from the inside of the suction cup 8, thereby using the suction cup 8 to install the fixed base 2 on the top of the table, preventing the fixed base 2 from tipping over. When the fixed base 2 is installed on the top of the table using the suction cup 8, the L-shaped support leg 6 is pulled outward, causing the L-shaped support leg 6 to slide outward along the inner side wall of the T-shaped rod 3, thereby fixing the fixed base 2 again through the L-shaped support leg 6, achieving the technical problem of the fixed base 2 being placed stably on uneven tabletops. When the tabletop is uneven, it is only necessary to rotate the screw 7 to extend the length of the screw 7 on the outside of the L-shaped support leg 6, so that the device can be placed on uneven tabletops. Finally, the scanning device body 1 is inserted into the fixed base 2 for convenient use.
