Description

Technical Field

[0001] This utility model belongs to the field of barcode scanner technology, specifically referring to a portable barcode scanner. Background Technology

[0002] As a widely used data acquisition tool, the portability and ease of operation of barcode scanners are crucial. Currently, barcode scanners on the market mainly exhibit two trends in grip design.

[0003] 1. Equipped with a fixed grip: Many barcode scanners feature a protruding grip fixed to the main body of the device to improve user comfort and stability. However, this fixed grip significantly increases the overall size and dimensions of the device, taking up a considerable amount of space.

[0004] 2. Complete omission of grip: In pursuit of ultimate miniaturization and portability, some barcode scanners completely omit the dedicated grip structure. Users can only operate the scanner by directly holding the main body shell. Although this method reduces the size, it is very inconvenient to hold in actual use. Utility Model Content

[0005] The technical problem this invention aims to solve is that current barcode scanners on the market occupy a large amount of space, or although they have reduced their size in pursuit of miniaturization and portability, they are not very convenient to hold in actual use.

[0006] To achieve the above functions, the technical solution adopted by this utility model is as follows: a portable barcode scanner includes a scanning head, two opposing support plates are provided at the bottom of the scanning head, a plurality of positioning grooves are provided on the support plates, a rotating shaft is rotatably provided at the center of the support plates, a handle is rotatably provided on the rotating shaft, and a limiting rod that engages with the positioning groove is movably provided on the handle.

[0007] Preferably, the grip has a hollow cavity structure, a sliding groove is provided on the grip, the limiting rod is slidably disposed on the sliding groove, and an elastic element is provided between the limiting rod and the rotating shaft.

[0008] Preferably, the elastic element includes a spring, one end of which is connected to a limiting rod, and the other end of which is connected to a rotating shaft.

[0009] Preferably, the bottom of the support plate is provided with an arc-shaped structure, and the positioning groove is provided around the bottom of the support plate.

[0010] Preferably, the top of the grip is provided with a partition cover, and the partition cover is provided with a groove corresponding to the slide groove.

[0011] Preferably, the sidewall of the grip is provided with anti-slip grooves.

[0012] The beneficial effects achieved by adopting the above-described structure are as follows:

[0013] 1. Through a simple "pull-rotate-release" operation, the handle can be quickly and reliably folded and stored at the bottom of the scanning head, significantly reducing the overall size and space occupied by the device. This solves the problems of inconvenience in carrying and easy snagging and collision caused by the fixed handle, greatly improving the portability and storage efficiency of the device.

[0014] 2. The core limit rod and spring design enable the "one-click unlock / lock" function. Users only need to pull the limit rod to unlock, and release it after rotating the handle to lock automatically. The whole process requires no tools, no disassembly of parts, and the steps are simple.

[0015] 3. The limiting rod is tightly engaged in the positioning groove of the support plate under the action of the spring, ensuring that the handle is firmly locked during use, without shaking or accidental folding, providing stable grip support and solving the problems of no handle or unstable grip.

[0016] 4. After folding into place, the limit bar will automatically engage with the corresponding positioning slot, reliably locking the handle in the storage position and preventing it from accidentally popping open during transportation and carrying. Attached Figure Description

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] like Figure 1-4 As shown, this utility model proposes a portable barcode scanner, including a scanning head 1. The bottom of the scanning head 1 is provided with two opposing support plates 2. The support plates 2 are provided with a plurality of positioning grooves 3. The bottom of the support plates 2 is provided with an arc-shaped structure. The positioning grooves 3 are provided around the bottom of the support plates 2. A rotating shaft 4 is rotatably provided at the center of the support plates 2. A handle 5 is rotatably provided on the rotating shaft 4. A limiting rod 6 is movably provided on the handle 5 and engages with the positioning grooves 3. When it is needed to carry, the limiting rod 6 is pulled to remove it from the positioning grooves 3. The handle 5 is rotated and folded under the scanning head 1. At this time, the limiting rod 6 engages with the positioning grooves 3 again for positioning.

[0025] like Figure 2 and 4 As shown, the grip 5 has a hollow cavity structure. The grip 5 is provided with a sliding groove 7. The limiting rod 6 is slidably disposed on the sliding groove 7. An elastic element 8 is provided between the limiting rod 6 and the rotating shaft 4. The top of the grip 5 is provided with a partition cover 10. The partition cover 10 is provided with a groove 11 corresponding to the sliding groove 7. The side wall of the grip 5 is provided with an anti-slip groove 12. The grip 5 is designed as a hollow cavity, and the elastic element 8 is cleverly built into it, thus optimizing the space.

[0026] like Figure 2 As shown, the elastic element 8 includes a spring 9. One end of the spring 9 is connected to the limiting rod 6, and the other end of the spring 9 is connected to the rotating shaft 4. When the limiting rod 6 is pulled and removed from the positioning groove 3, the spring 9 undergoes elastic deformation, and the handle 5 can be folded or unfolded by rotating the rotating shaft 4. When the pulling force on the limiting rod 6 is released, the limiting rod 6 is inserted back into the positioning groove 3 under the elastic force of the spring 9, thus positioning the handle 5.

[0027] In actual use, when unfolded, the handle 5 is rotated to the use position via the pivot 4. At this time, the elastic force generated by the spring 9 inside the handle 5 pulls the limiting rod 6 to slide inward along the slide groove 7 on the handle 5, so that its end is firmly locked into the positioning groove 3 at the bottom of the support plate 2 corresponding to the current angle, locking the handle 5. The user can comfortably and stably hold the anti-slip groove 7 part for operation.

[0028] Fold the handle 5 from the unfolded state. The operator pulls the limiting rod 6 on the handle 5 outward (overcoming the elastic force of the spring 9) so that it slides outward along the slide groove 7 until its end is completely disengaged from the positioning groove 3 of the support plate 2. While maintaining the tension on the limiting rod 6, the operator rotates the handle 5 towards the bottom of the scanning head 1 with the rotating shaft 4 as the rotation center. When the handle 5 is rotated to the predetermined folding and storage position close to or close to the bottom of the scanning head 1, the operator releases the limiting rod 6. The elastic force of the internal spring 9 will immediately drive the limiting rod 6 to automatically reset and slide inward along the slide groove 7, so that its end is locked into the folding positioning groove 3 of the bottom of the support plate 2, which is now aligned. This reliably locks the handle 5 in the folded state, significantly reducing the size of the device and making it easy to put into a bag or toolbox.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
