[0007] As a further description of the above technical solution: The surface of the bump is provided with multiple protrusions and grooves, which are arranged in a ring at equal intervals on the surface of the bump. The central axis of the rotating shaft coincides with the central axis of the slider.

[0008] As a further description of the above technical solution: The settlement mechanism also includes a support plate, which is hinged to the inner wall of the base.

[0009] As a further description of the above technical solution: The number of the limiting grooves is set to multiple, and the multiple limiting grooves are arranged in a straight line at equal intervals on the front of the stand.

[0010] As a further description of the above technical solution: The stabilizing mechanism also includes a suction cup, the top of which is fixedly connected to a screw, which is threaded onto the inner wall of the fixing column.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a weighing and settlement device for a smart canteen, including a base 1 for stable support. A connecting plate 2 is provided above the base 1. A display panel 3 for convenient viewing and operation of food information and prices is fixedly connected to the end of the connecting plate 2 away from the base 1. A storage mechanism is provided inside the base 1, including a rotating shaft 4. The rotating shaft 4 is fixedly installed at the bottom of the connecting plate 2 and rotatably installed on the inner wall of the base 1. By rotating the rotating shaft 4, the display panel 3 can be rotated from a vertical state to a horizontal state, which is convenient for storage when the equipment is not in use and reduces the volume occupied.

[0019] Reference Figure 2 - Figure 3The storage mechanism also includes a knob 5. By setting the knob 5, the friction between the user's palm and the knob 5 can be increased, making it easier and less strenuous to operate. A threaded rod 6 is fixedly connected to the right side of the knob 5. The threaded rod 6 passes through and is threaded onto the inner wall of the base 1. When the threaded rod 6 rotates, it will also make linear displacement in the left and right directions. A slider 7 is rotatably connected to the right side of the threaded rod 6. The slider 7 is slidably installed on the inner wall of the base 1. The sliding direction of the slider 7 is left and right. Both the right side of the slider 7 and the left side of the rotating shaft 4 are fixedly connected to protrusions 8. The surface of the protrusions 8 is provided with multiple protrusions and grooves. The multiple protrusions and grooves are arranged in a ring at equal intervals on the surface of the protrusions 8. By setting the protrusions 8, when the rotating shaft 4 and the slider 7 approach and contact each other, the two sets of protrusions 8 interlock with each other, which will restrict the rotation of the rotating shaft 4 and fix the display panel 3 in a suitable position to avoid shaking during operation. The central axis of the rotating shaft 4 and the central axis of the slider 7 coincide.

[0020] Reference Figure 1 , Figure 4 The base 1 has a settlement mechanism on its top, which includes a stand 9 hinged to the inner wall of the base 1. The stand 9 can be rotated to contact the inner wall of the base 1, thus storing the stand 9. The stand 9 has a slot 10 inside, into which a pre-printed payment code can be inserted for customers to scan and pay for the food. The front of the stand 9 has a limiting groove 12. The settlement mechanism also includes a support plate 11 that is tilted and hinged to the inner wall of the base 1. There are multiple limiting grooves 12, which are arranged in a straight line at equal intervals on the front of the stand 9. By inserting the support plate 11 into the limiting grooves 12 at different positions, the tilt angle of the stand 9 can be changed, thus facilitating the adjustment of the display angle of the stand 9 to align with the customer's field of vision.

[0021] Reference Figure 1 , Figure 5The base 1 has a stabilizing mechanism fixedly connected to its bottom. The stabilizing mechanism includes a cylindrical fixing column 13, which is fixedly installed at the bottom of the base 1. The top of the base 1 has a weighing area 16 for placing and weighing the dishes selected by the customer. The weighing area 16 is equipped with a gravity sensor to facilitate accurate measurement and transmit the data to the display panel 3. This is existing technology. The base 1 has a cashier mechanism inside. The stabilizing mechanism also includes suction cups 14. By setting the suction cups 14, the base 1 is firmly fixed to the table, improving the stability of the base 1 during operation. Multiple suction cups 14 are symmetrically arranged at the bottom of the base 1. The top of the suction cups 14 is fixedly connected with screws 15, which are threaded onto the inner wall of the fixing column 13. By rotating the screws 15, the distance between the suction cups 14 and the fixing column 13 can be adjusted to easily adjust the level of the base 1 and prevent the base 1 from tilting, which would affect the safety of placing the dishes in the weighing area 16.

[0022] Reference Figure 1 The cash register includes a cash box 17 for storing and receiving cash. The cash box 17 is slidably mounted on the inner wall of the base 1. A handle 18 is fixedly connected to the front of the cash box 17 for easy pulling.

[0023] Working principle: During use, rotating knob 5 causes threaded rod 6 to rotate, which in turn moves slider 7 to the left, causing slider 7 to disengage from rotating shaft 4. This removes the constraint of protrusion 8 from rotating shaft 4, allowing connecting plate 2 to rotate display panel 3 to a horizontal position for storage. Then, rotating knob 5 in the opposite direction causes protrusion 8 on the right side of slider 7 and protrusion 8 on the left side of rotating shaft 4 to engage, thus securing display panel 3 and preventing accidental opening during storage or transportation, which could damage the equipment. This also reduces the overall size of the equipment, improving space utilization.

[0024] By rotating the stand 9 and the support plate 11, the support plate 11 can be removed from the inside of the limiting groove 12, and both the support plate 11 and the stand 9 can be stored inside the base 1. This also reduces the overall volume of the equipment and maximizes the space utilization during transportation and storage.

[0025] By rotating the screw 15, the distance between each suction cup 14 and the bottom of the base 1 can be adjusted individually. This allows the base 1 to be leveled when placed, improving control precision and safety. At the same time, the screw 15 can be removed from inside the fixing post 13, further reducing the overall space utilization of the equipment.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
