Therefore, the phrases "one embodiment," "some embodiments," "other embodiments," "and other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0025] This utility model provides a barcode scanner with stepless angle adjustment and hovering function, referencing... Figures 1 to 3 The barcode scanner with stepless angle adjustment and hovering function includes a head assembly 10, a base 20, a pressure plate 30, a rotating shaft 40, and a pad 50.

[0026] Specifically, the base 20 is located below the head assembly 10. The base 20 contains a first cavity 21 with a semi-circular cross-section. A pressure plate 30 is located inside the base 20, and the pressure plate 30 has a second cavity 31 with a semi-circular cross-section. The second cavity 31 corresponds to the lower part of the first cavity 21, and the first cavity 21 and the second cavity 31 cooperate to form a mounting cavity with a circular cross-section. The rotating shaft 40 has a cylindrical structure and is located within this mounting cavity. A gasket 50 is located on the inner wall of the second cavity 31, and the gasket 50 forms a damping fit with the rotating shaft 40.

[0027] The base 20 has an adjustment hole 22 on its top side, which communicates with the first cavity 21. The head assembly 10 has a connecting bracket 11 at its bottom, which passes through the adjustment hole 22 and is connected to the rotating shaft 40.

[0028] This barcode scanner has a simple structure and is easy to manufacture. The rotating shaft 40 is installed in the mounting cavity formed between the base 20 and the pressure plate 30. The connecting bracket 11 is fixedly connected to the rotating shaft 40. Through the damping cooperation between the gasket 50 and the rotating shaft 40, an adjustable stepless hovering structure is formed, allowing the head assembly 10 to stay stably at any angle within the allowable range. This design breaks through the fixed angle limitation of traditional barcode scanners and can meet the flexible adjustment needs of multiple scenarios. The first cavity 21 and the second cavity 31 form a cylindrical mounting cavity, which not only ensures the coaxiality of the rotating shaft 40 assembly, but also reduces the processing difficulty and cost through the split structure.

[0029] Reference Figure 2 In some preferred embodiments, the rotating shaft 40 is provided with a fitting groove 41, the depth direction of which corresponds to the radial direction of the rotating shaft 40. The structure of the fitting groove 41 matches the structure of the connecting bracket 11, and the connecting bracket 11 is inserted into the fitting groove 41. The fitting groove 41 provides a constraint and positioning function for the connecting bracket 11, ensuring the reliability of the connection between the connecting bracket 11 and the rotating shaft 40.

[0030] Furthermore, a recessed groove 42 is provided on the other side of the rotating shaft 40 corresponding to the fitting groove 41. The depth direction of the recessed groove 42 corresponds to the radial direction of the rotating shaft 40, and the recessed groove 42 communicates with the fitting groove 41. A screw 60 is provided in the recessed groove 42, and a corresponding screw hole 111 is provided in the connecting bracket 11. The screw 60 is engaged with the screw hole 111 for connection.

[0031] In the connection and assembly operation of the connecting bracket 11 and the rotating shaft 40, first insert the connecting bracket 11 into the corresponding fitting groove 41, then insert the screw 60 into the countersunk groove 42, and finally tighten the screw 60 into the screw hole 111 of the connecting bracket 11.

[0032] Of course, this utility model is not limited to this. In other embodiments, the connecting bracket 11 and the rotating shaft 40 can also adopt other suitable detachable connection methods.

[0033] In some preferred embodiments, limiting surfaces 23 are provided on both sides of the adjusting hole 22, and the connecting bracket 11 is located between the two limiting surfaces 23. The two limiting surfaces 23 can be used to limit the rotation range of the connecting bracket 11, so that the connecting bracket 11 can be adjusted arbitrarily between a first position and a second position. The first position corresponds to the left side wall of the connecting bracket 11 abutting against the left limiting surface 23, and the second position corresponds to the right side wall of the connecting bracket 11 abutting against the right limiting surface 23. At the same time, the two limiting surfaces 23 can also play a role in preventing over-rotation protection.

[0034] Furthermore, the included angles between the two limiting surfaces 23 and the bottom surface of the base 20 are each greater than 15°. This prevents the scanner from tipping over due to a change in the center of gravity of the head assembly 10 during angle adjustment. (Refer to...) Figure 2 In some preferred embodiments, the left limiting surface 23 corresponds to the front side of the head assembly 10, and the right limiting surface 23 corresponds to the rear side of the head assembly 10. The angle between the left limiting surface 23 and the bottom surface of the base 20 is 20°, the angle between the right limiting surface 23 and the bottom surface of the base 20 is 17°, and the angle between the two limiting surfaces 23 is 143°. However, this invention is not limited to these embodiments. In other embodiments, the angle between the two limiting surfaces can be reasonably set according to the actual weight of the head assembly, etc.

[0035] Reference Figure 2 and Figure 3 Along the central axis of the rotating shaft 40, the length of the adjusting hole 22 is less than the length of the rotating shaft 40. Furthermore, the adjusting hole 22 corresponds to the axial center position of the first cavity 21, and both ends of the rotating shaft 40 are covered by the base 20. In this way, the rotating shaft 40 can be prevented from coming out of the base 20, ensuring the structural stability and reliability of the barcode reader.

[0036] In some preferred embodiments, a counterweight 24 is provided inside the base 20. The counterweight 24 can be configured as a plate, block, or other structure. The counterweight 24 is used to lower the center of gravity of the barcode scanner, improve the overall stability of the barcode scanner, and prevent the barcode scanner from shifting during angle adjustment.

[0037] In some preferred embodiments, the head assembly 10 is provided with a scanning window 12, an image sensor and other devices to realize scanning, decoding and other functions, and the central axis of the rotating shaft 40 is parallel to the plane where the scanning window 12 is located.

[0038] Furthermore, the head assembly 10 has a rear cover 13, and the connecting bracket 11 is integrally connected to the rear cover 13, which can improve production efficiency and reduce process costs.

[0039] In some preferred embodiments, the pad 50 is made of silicone. The friction between the pad 50 and the pivot 40 creates a damping effect, ensuring that the head assembly can hover at any position within the permissible angle range. However, this invention is not limited to this; in other embodiments, the pad 50 can also be made of other suitable materials, as long as it can form a damping engagement with the pivot 40 to achieve the angle-adjusting hovering function.

[0040] The barcode scanner of this utility model has a simple structure and is easy to manufacture. The rotating shaft is installed in the cylindrical mounting cavity formed between the base and the pressure plate. The connecting bracket is fixedly connected to the rotating shaft. Through the damping cooperation between the gasket and the rotating shaft, an adjustable stepless hovering structure is formed, which allows the head assembly to stay stably at any angle within the allowable range. This design breaks through the fixed angle limitation of traditional barcode scanners and can meet the flexible adjustment needs of multiple scenarios.

[0041] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
