DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0028] See also Figure 1 - Fig.10 In an embodiment of the present invention, a code scanning device for mechanically widening the range of a collection lens includes: a base 1, a grip arm 2, a scanning terminal 3, a scanning component 4, a connecting component, a power component, an inserting component, and a locking component, so that the grip arm 2 has two use states, namely a hand-held state and a placed state, and the two states can be switched according to the use scenario. By switching between the two states, the practicality of the code scanning device is improved, and in the hand-held state, the grip arm 2 and the scanning terminal 3 cannot rotate relative to each other, so that the code scanning in the hand-held state is more stable, and in the placed state, the scanning terminal 3 can change the height while maintaining a horizontal state, thereby improving the code scanning effect, as follows: The gripping arm 2 is rotatably connected to the sweeping dock 3; The scanning component 4 is disposed in the scanning terminal 3, the scanning component 4 is adapted to the through hole 301 formed on the scanning terminal 3, and the scanning component 4 is connected to the driving component disposed in the scanning terminal 3; A guide 5 is provided in the scanning terminal 3, and the scanning component 4 is slidably connected to the guide 5; The driving assembly includes a stepping driving device 6 fixedly installed in the sweeping dock 3, and a convex shaft 7 is rotatably installed on the stepping driving device 6; The driving assembly further includes a driving plate 8 which is parallel to and fixedly connected to the scanning member 4. A guide groove 9 is formed on the driving plate 8. The guide groove 9 cooperates with the convex shaft 7 to drive the scanning member 4 to move stepwise toward or away from the through hole 301. The guide groove 9 includes a stepped groove that is sequentially connected and arranged on the driving plate 8 , and the stepped groove includes an inclined groove 901 and a straight groove 902 . When the convex shaft 7 moves along the inclined groove 901 , the scanning member 4 can move toward or away from the through hole 301 .

[0029] When in use, the stepping drive device 6 is controlled to move, which can drive the cam 7 to move in steps along the length direction of the stepping drive device 6. The length of a single movement of the cam 7 is equal to the length of a step groove. At the same time, in the initial state, the cam 7 is located in the straight groove 902 in the step groove. At this time, since the length direction of the straight groove 902 is perpendicular to the movement direction of the scanning piece 4, it has a positioning effect on the scanning piece 4, preventing the scanning piece 4 from moving in the scanning terminal 3, thereby changing the range of the collecting lens and improving the scanning accuracy under predetermined conditions.

[0030] In this embodiment, a distance sensor is provided on the scanning terminal 3. The distance sensor actively controls the action of the stepping drive device 6 by detecting the distance between the QR code and the scanning piece 4. When the stepping drive device 6 is in action, the cooperation between the convex shaft 7 and the inclined groove 901 can be utilized to make the scanning piece 4 move toward or away from the through hole 301 under the guidance of the guide member 5, thereby changing the range of the collective lens. When the stepping drive device 6 stops moving, the convex shaft 7 can be moved again into the straight groove 902, thereby improving the stability of the scanning piece 4 after the position is changed.

[0031] Through the above-mentioned arrangement, with the cooperation of the convex shaft 7 and the straight groove 902, the scanning component 4 can have better position stability in the initial state and after the position is changed, thereby improving the scanning accuracy under predetermined conditions. At the same time, with the cooperation of the convex shaft 7 and the inclined groove 901, the scanning component 4 can change its position under the guidance of the guide 5, thereby changing the range of the collective lens to adapt to the scanning requirements under different conditions.

[0032] It should be noted that by changing the distance between the scanner 4 and the through hole 301, the beam angle of the light emitted by the scanner 4 and passing through the through hole 301 can be changed, so that the light range can be increased or decreased, which is more conducive to the effective acquisition of the two-dimensional code information.

[0033] See also Figure 6 , Fig. 9 - Fig.10 The connecting assembly is arranged in the grip arm 2 and connected to the rotating shaft of the sweeping dock 3. A first gear 12 is arranged on the connecting assembly. Specifically, the first gear 12 is fixedly connected to the grip arm 2; The connecting assembly includes a sleeve shaft 11 rotatably sleeved with the rotating shaft of the first gear 12, the sleeve shaft 11 penetrates the handle arm 2 to form a first rotating pin, and a connecting shaft 201 is provided on the other side of the handle arm 2, the connecting shaft 201 is coaxial with the first rotating pin and forms a second rotating pin, and the first rotating pin and the second rotating pin have the same diameter; The connecting assembly also includes two connecting wheels coaxial with the rotating shaft of the sweeping dock 3 and the sleeve shaft 11, and a connecting belt 10 is sleeved between the two connecting wheels, so that the sweeping dock 3 can be kept in a horizontal state when the sleeve shaft 11 is fixed and the grip arm 2 is deflected; The power member is mounted on the base 1, and the power member is adapted to the first gear 12. The power member includes a driving motor 13 fixedly mounted on the base 1, and a second gear 14 is coaxially fixedly mounted on the output shaft of the driving motor 13, and the second gear 14 is adapted to the first gear 12; An abutment wheel 1301 is coaxially fixedly mounted on the output shaft of the driving motor 13 , and the abutment wheel 1301 is adapted to the locking assembly.

[0034] When the gripping arm 2 is mounted on the base 1, the sleeve shaft 11 can be locked under the action of the inserted component. At the same time, in this state, the number one gear 12 and the number two gear 14 are in a meshing state, so that when the driving motor 13 works and drives the number two gear 14 to rotate, the number one gear 12 can be driven to rotate through the meshing action of the number one gear 12 and the number two gear 14, thereby driving the gripping arm 2 to swing. Since the sleeve shaft 11 is in a locked state and the sleeve shaft 11 is connected to the rotating shaft of the scanning terminal 3 through the connecting belt 10, when the gripping arm 2 swings, the scanning terminal 3 can always remain in a horizontal state. Due to the swing of the gripping arm 2, the height of the scanning terminal 3 changes, thereby achieving the purpose of adjusting the height of the scanning terminal 3 while keeping the scanning terminal 3 in a horizontal state, thereby ensuring the scanning effect.

[0035] See also Figure 7 The inserted component is arranged on the base 1, and the inserted component can make the lower end of the grip arm 2 and the base 1 form a rotational connection state when the power member cooperates with the first gear 12; The insertion assembly includes a retardation groove 23 disposed on the inner side of the base 1, and an insertion member 24 is detachably installed in the retardation groove 23, and an arc portion 2401 is formed at one end of the insertion member 24, and a columnar groove is formed between the arc portion 2401 and the end of the retardation groove 23, and the first rotating pin and the second rotating pin can rotate in the columnar groove; A locking groove 2301 is provided inside the retardation groove 23, and the locking member 22 provided at the end of the sleeve shaft 11 can slide in the locking groove 2301; The insertion component also includes a locking structure for locking the insertion member 24, and the locking structure can be locked in position after the insertion member 24 is inserted into the retardation groove 23. The locking structure includes a locking groove 2402 formed on the insertion member 24, and a pin 25 slidingly arranged through the base 1 is adapted to the locking groove 2402.

[0036] When the grip arm 2 is installed on the base 1, it is necessary to first remove the insert 24 and the latch 25, and then align the first rotating pin and the second rotating pin with the retardation groove 23 and insert them. After the first rotating pin and the second rotating pin are inserted into the ends of the retardation groove 23, the first gear 12 can maintain an engagement state with the second gear 14, and the abutment wheel 1301 cooperates with the locking assembly to unlock the sleeve shaft 11. At this time, the scanning terminal 3 can rotate relative to the grip arm 2, and the locking piece 22 at the end of the sleeve shaft 11 is locked by the locking groove 2301, so that when the grip arm 2 does not rotate, the scanning terminal 3 cannot rotate either. Subsequently, the insert 24 and the latch 25 are installed in turn, so that the first rotating pin and the second rotating pin can rotate in the cylindrical groove, and when the drive motor 13 works to make the grip arm 2 deflect, the scanning terminal 3 can maintain a horizontal state and change its height, so that the barcode scanner can perform a barcode scanning action at different heights, thereby improving the success rate of barcode scanning.

[0037] When the handle arm 2 is disassembled, the locking assembly can lock the sleeve shaft 11, thereby preventing the scanning terminal 3 from deflecting when the handle arm 2 is held, thereby improving the stability of the scanning terminal 3 when the handheld device scans the code.

[0038] Through the above arrangement, the grip arm 2 has two usage states, namely, a hand-held state and a placed state. The two states can be switched according to the usage scenario. By switching between the two states, the practicability of the code scanning device is improved, the complexity of the entire cash register system is reduced, and the operation process is simplified. In the hand-held state, the grip arm 2 and the scanning terminal 3 cannot rotate relative to each other, which makes the code scanning in the hand-held state more stable, avoiding the relative rotation between the grip arm 2 and the scanning terminal 3 when the hand-held code scanning machine is used, which causes the unstable code scanning. At the same time, in the placed state, the scanning terminal 3 can change the height while maintaining a horizontal state, thereby improving the code scanning effect.

[0039] See also Fig. 9 - Fig.10 , the locking assembly is connected to the connecting assembly and is adapted to the power member, the locking assembly can lock or release the connecting assembly, the locking assembly includes a friction wheel 15 coaxially fixedly connected to the sleeve shaft 11 and an energy storage structure fixedly installed on the inner side of the grip arm 2, the energy storage structure is connected to a connecting frame 17, a friction member 18 adapted to the friction wheel 15 is installed in the connecting frame 17, and when the friction member 18 abuts against the friction wheel 15, the sleeve shaft 11 can be locked; The end of the connecting frame 17 away from the energy storage structure is also rotatably mounted with a trigger wheel 16, and the trigger wheel 16 is adapted to the abutment wheel 1301; The energy storage structure is fixedly mounted on a hysteresis sleeve 21 on the inner wall of the grip arm 2, a vertical shaft 19 is slidably mounted in the hysteresis sleeve 21, and the vertical shaft 19 is fixedly connected to the connecting frame 17; A limit ring 1901 is disposed on the vertical shaft 19 , and a cylindrical spring 20 is sleeved on the vertical shaft 19 . One end of the cylindrical spring 20 is connected to the inner wall of the hysteresis sleeve 21 , and the other end is connected to the limit ring 1901 .

[0040] When the barcode scanning device is held in the hand, the abutment wheel 1301 and the trigger wheel 16 are in a separated state. At this time, the elastic force provided by the cylindrical spring 20 can drive the vertical shaft 19 to move downward, and make the friction member 18 abut against the friction wheel 15, thereby locking the sleeve shaft 11. At this time, the connecting belt 10 is in a locked state, so that the grip arm 2 and the scanning terminal 3 cannot rotate relative to each other. In the placed state, the abutment wheel 1301 and the trigger wheel 16 are in an abutment state, so that the trigger wheel 16 can drive the connecting frame 17 to move upward, compressing the cylindrical spring 20 while making the friction member 18 and the friction wheel 15 separated, and making the sleeve shaft 11 able to rotate relative to the grip arm 2, so that when the grip arm 2 swings relative to the base 1, the sleeve shaft 11 can rotate relative to the grip arm 2, and the scanning terminal 3 is kept in a horizontal state through the connecting belt 10.

[0041] Through the above arrangement, the sleeve shaft 11 and the grip arm 2 can be locked or relatively rotated, so that when the handheld code scanning device is held, the scanning terminal 3 can be locked with the grip arm 2, that is, they cannot rotate relatively. At this time, the scanning terminal 3 and the grip arm 2 are integrated, which improves the stability during handheld code scanning and avoids the deflection of the scanning terminal 3, which makes scanning inconvenient. At the same time, when it is placed, the height of the scanning terminal 3 can be changed and the scanning terminal 3 can be kept horizontal, so that the scanning terminal 3 has a better scanning effect when it is placed.

[0042] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
