Description

Technical Field

[0001] The invention relates to the technical field of cash registers, in particular to a double-screen cash register with high stability. Background Art

[0002] With the continuous development of commerce, cash registers have been widely used in various retail, catering and other places. Traditional single-screen cash registers are gradually unable to meet the needs of merchants and customers, and dual-screen cash registers have come into being. Dual-screen cash registers usually have a main screen for cashiers and a secondary screen for customers, which can improve the transparency and efficiency of transactions. However, there are still some problems with the dual-screen cash registers on the market during use. Among them, the stability of the cash register on the desktop needs to be improved, which is a more prominent problem. There is often a large flow of people during the use of the cash register, which may cause the cash register to be affected by some slight collisions, vibrations or external forces during operation, which may easily cause it to shake or tilt on the desktop, or even fall, thereby affecting the normal cash register work, and may even cause equipment damage and data loss.

[0008] The lifting assembly includes a casing, which is fixedly connected to the base. Two L-shaped plates are fixedly installed on the inner wall of the casing. Screw rods are rotatably installed on the top ends of the inner walls of the two L-shaped plates. One end of the outer wall of the two screw rods respectively penetrates the bottom ends of the two L-shaped plates and is fixedly installed with a second bevel gear.

[0009] Preferably, four support frames are fixedly mounted on the bottom end of the base, the four support frames are slidably connected to four movable racks respectively, and a movable plate is fixedly mounted on one end of the outer wall of the four movable racks.

[0010] Preferably, the top ends of the four movable plates are fixedly installed with threaded sleeves, the inner walls of the four threaded sleeves are threadedly connected with threaded rods, the bottom ends of the four threaded rods respectively pass through the bottom ends of the four movable plates, and are respectively fixedly connected to the four supporting circular plates, and the top ends of the four threaded rods are fixedly installed with rotating plates.

[0015] Preferably, a damping shaft is fixedly mounted on the outer walls of the two sliding blocks, a main display screen is fixedly mounted on the outer wall of one of the two damping shafts, and a secondary display screen is fixedly mounted on the outer wall of one of the two damping shafts.

[0016] Beneficial Effects

[0017] The present invention provides a highly stable dual-screen cash register. Compared with the prior art, it has the following beneficial effects:

[0018] (1) When the highly stable dual-screen cash register is placed on a desktop, in order to improve the stability of the device, the first motor can be turned on. The first motor drives the outer gear ring to rotate through the second gear, and the outer gear ring drives the inner gear ring to rotate. When the inner gear ring rotates, it drives the four first gears to rotate. The four first gears then drive the four moving racks to move outward and extend. The four moving racks then drive the four supporting circular plates to move outward and extend. Then the rotating plate is rotated. The rotating plate drives the threaded rod to rotate in the threaded sleeve. As the threaded rod rotates, the supporting circular plate contacts the desktop, thereby increasing the support points between the device and the desktop. Extending the support points to all sides can expand the contact range between the cash register and the desktop. This allows the cash register to have a larger support base to maintain stability when subjected to external forces, such as slight collisions or vibrations. When the cash register is hit from the side, the support points on all sides can provide additional resistance to prevent the cash register from tipping over. At the same time, the distribution of multiple support points can make the center of gravity of the cash register more stable. By reasonably arranging the support points, the center of gravity can be located near the center of the support area, reducing the risk of tilting due to center of gravity shift.

[0019] (2) When the high-stability dual-screen cash register is used by customers and cashiers of different heights, it is necessary to adjust the heights of the main display screen and the auxiliary display screen to improve the use effect. At this time, the rotation of the two first bevel gears can be controlled separately by a dual-axis motor. When the first bevel gear rotates, it drives the second bevel gear to rotate, and the second bevel gear can drive the screw rod to rotate. During the rotation process, the screw rod drives the slider to rise and fall. The two sliders can control the main display screen and the auxiliary display screen to rise and fall respectively, thereby facilitating use by users of different heights.

[0020] (3) The high-stability dual-screen cash register is equipped with damping shafts on the back of the main display screen and the auxiliary display screen. When the main display screen and the auxiliary display screen are raised or lowered to a suitable height, the display screen can be adjusted to the most comfortable viewing angle through the damping shaft according to one's sitting posture and actual working environment. The damping shaft can provide stable support to ensure that the display screen remains stable after being adjusted to any angle. Compared with ordinary shafts, the damping shaft will not easily change angle due to slight touch or vibration, thus avoiding interference caused by the shaking of the display screen.

[0040] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0041] During operation, when the device is placed on a desktop, in order to improve the stability of the device, the first motor 115 can be turned on. The first motor 115 drives the outer gear ring 14 to rotate through the second gear 116, and the outer gear ring 14 drives the inner gear ring 13 to rotate. When the inner gear ring 13 rotates, it drives the four first gears 15 to rotate. The four first gears 15 then drive the four moving racks 16 to move and extend outward. The four moving racks 16 then drive the four supporting circular plates 111 to move and extend outward, and then the rotating plate 113 is rotated. The rotating plate 113 drives the threaded rod 112 to rotate in the threaded sleeve 110. As the threaded rod 112 rotates, the supporting circular plate 111 contacts the desktop, thereby increasing the support points between the device and the desktop. Extending the support points to all sides can expand the contact range between the cash register and the desktop. This allows the cash register to have a larger support base to remain stable when subjected to external forces, such as minor collisions or vibrations. When the cash register is hit from the side, the support points on all sides can provide additional resistance to prevent the cash register from tipping over. At the same time, the distribution of multiple support points can make the center of gravity of the cash register more stable. By reasonably arranging the support points, the center of gravity can be located near the center of the support area, reducing the risk of tilting caused by the offset of the center of gravity. When encountering customers and cashiers of different heights, it is necessary to adjust the height of the main display screen 25 and the auxiliary display screen 26 to improve the use effect. At this time, the rotation of the two first bevel gears 28 can be controlled separately by the double-axis motor 27. When the first bevel gear 28 rotates, it drives the second bevel gear 29 to rotate, and the second bevel gear 29 can drive the screw rod 22 to rotate. The screw rod 22 drives the slider 23 to rise and fall during the rotation process. The two sliders 23 can control the main display screen 25 and the auxiliary display screen 26 to rise and fall respectively, thereby facilitating the use of users of different heights. A damping shaft 24 is provided on the back of the main display screen 25 and the auxiliary display screen 26. When the main display screen 25 and the auxiliary display screen 26 are lifted to a suitable height, the display screen can be adjusted to the most comfortable viewing angle through the damping shaft 24 according to one's sitting posture and actual working environment. The damping shaft 24 can provide a stable supporting force to ensure that the display screen can remain stable after being adjusted to any angle. Compared with an ordinary shaft, the damping shaft 24 will not easily change its angle due to a slight touch or vibration, thereby avoiding interference with use caused by the shaking of the display screen.
