Description

Technical Field

[0001] The present invention relates to the technical field of dinner plates, and particularly relates to a stable dinner plate convenient for dining in a restaurant and a cleaning mechanism for the dinner plate. Background Art

[0002] Plates are a kind of tableware we use daily and can be used to hold fruits and dishes.

[0003] Chinese Invention Patent Publication No. CN 110269463 B. This application relates to an anti-overturning children's dinner plate in the field of children's dinner plates. The dinner plate includes a device base body. The lower base is placed on the tabletop. By pressing the fixing component, under the action of atmospheric pressure, the rubber suction cup is attached to the tabletop. The lower base can be attached to the tabletop through the rubber suction cup. When a child uses it, the lower base cannot be pushed to move, preventing the child from pushing the dinner plate. After the upper base and the lower base are connected, they can move up and down but cannot rotate. When rotation is needed, the upper base needs to be lifted up before rotation. Therefore, when a child uses it, the dinner plate will not be overturned or moved. Parents only need to help rotate the dinner plate beside, meeting the needs of the family.

[0004] Most of the plates in the restaurant are fixed and cannot provide convenience for the dining of special groups. For some people with diseases or special conditions, their hands will keep shaking during the meal, resulting in the phenomenon that the dinner plate is easily overturned during use, easily causing body burns or food waste. Moreover, the existing stable dinner plates use magnets to fix them to the tabletop, making it require a lot of force to disassemble the stable dinner plate, which is not conducive to quick disassembly and easily causes the food in the dinner plate to spill out, adding trouble to cleaning. Summary of the Invention

[0005] Based on the above ideas, the present invention provides the following technical solutions:

The second gear 516 drives the elastic hole belt 517 to rotate clockwise. The elastic hole belt 517 drives the partition belt 518 to gradually move to one side of the hook-and-loop female surface 510. At the same time, the double-sided cylindrical rack 514 drives the third gear 521 to rotate counterclockwise. The third gear 521 drives a plurality of teeth to move upward synchronously. The plurality of teeth drive the support base 2 to move upward gradually.

The outer wall of the limit rod slidably penetrates through the side wall of the limit block. A telescopic spring is sleeved on the outer wall of the limit rod. One end of the telescopic spring is fixedly connected to the top of the limit block. The bottom end of the T-shaped cylindrical protrusion is fixedly connected with a double-sided cylindrical rack. The bottom end of the double-sided cylindrical rack slidably penetrates through the side wall of the arc-shaped plate and is located in the strip groove.

[0048] The working principle of the present invention is as follows: Press the dinner plate 3 downward along the tops of multiple wedge-shaped blocks 403 and gradually move it between the opposite sides of multiple wedge-shaped blocks 403, and finally place it on the top of the support seat 2. When the dinner plate 3 is taken away, multiple T-shaped blocks 402 drive multiple wedge-shaped blocks 403 to approach each other under the elastic force of multiple return springs 404, so as to centrally fix and clamp the position of the support seat 2, avoid the dinner plate 3 from tipping over or being knocked over under the action of external forces, causing burns to children or personnel, and can also clamp and fix dinner plates of different diameters, meeting the clamping of different types of dinner plates.

[0049] During the downward movement of the dinner plate 3, the hook-and-loop male surface 301 gradually fits with the hook-and-loop female surface 510. At this time, the hook-and-loop female surface 510 drives the T-shaped cylindrical protrusion 509 to gradually move downward along the placement groove 503 and the cylindrical groove 504. The T-shaped cylindrical protrusion 509 drives the hook-and-loop female surface 510 on its top to move synchronously and drives the limit block 511 on its outer wall to move synchronously to the bottom of the lifting groove 507. The telescopic spring 513 gradually elongates. The double-sided cylindrical rack 514 also moves downward under the drive of the T-shaped cylindrical protrusion 509. The elastic hole belt 517 gradually shortens. The first gear 515 rotates clockwise and drives the coaxially connected second gear 516 to rotate together. The second gear 516 drives the elastic hole belt 517 to rotate clockwise. The elastic hole belt 517 drives the partition belt 518 to gradually move to one side of the hook-and-loop female surface 510. At the same time, the double-sided cylindrical rack 514 drives the third gear 521 to rotate counterclockwise. The third gear 521 drives multiple teeth to move upward synchronously. Multiple teeth drive the support seat 2 to gradually move upward. At this time, the support seat 2 supports the bottom of the dinner plate 3 to improve the stability of the dinner plate 3. At this time, the piston plate 519 moves downward under the drive of the double-sided cylindrical rack 514. The air pressure in the first cylindrical sleeve 101 gradually decreases. At this time, the suction cup 520 no longer fits tightly with the desktop.

[0050] When disassembling the dinner plate 3, pick up the dinner plate 3 upward. The dinner plate 3 drives the hook surface 301 of the magic tape to move synchronously. The hook surface 301 of the magic tape drives the loop surface 510 of the magic tape to move together. The loop surface 510 of the magic tape drives the T-shaped cylindrical protrusion 509 and the double-sided cylindrical rack 514 to move upward together. The T-shaped cylindrical protrusion 509 drives the limiting block 511 on its outer wall to move synchronously to the top of the lifting groove 507. The telescopic spring 513 gradually contracts and returns to its original position. The double-sided cylindrical rack 514 also moves upward under the drive of the T-shaped cylindrical protrusion 509. The elastic hole belt 517 gradually elongates. The first gear 515 rotates counterclockwise and drives the coaxially connected second gear 516 to rotate together. The second gear 516 drives the elastic hole belt 517 to rotate counterclockwise. The elastic hole belt 517 drives the partition belt 518 to gradually move to the top of the loop surface 510 of the magic tape. At the same time, the double-sided cylindrical rack 514 drives the third gear 521 to rotate clockwise. The third gear 521 drives a plurality of teeth to move downward synchronously. The plurality of teeth drive the support seat 2 to gradually move downward. At this time, the piston plate 519 moves upward under the drive of the double-sided cylindrical rack 514. The air pressure in the first cylindrical sleeve 101 gradually increases. At this time, the suction cup 520 fits tightly with the tabletop to fix the position of the bottom tray 1, further strengthening the stability of the support seat 2 and the dinner plate 3, reducing the pulling force when the hook surface 301 of the magic tape is separated from the loop surface 510 of the magic tape, realizing that during the process of picking up the dinner plate 3, the suction cup 520 adsorbs the tabletop, enabling the bottom tray 1 and the support seat 2 to act on the dinner plate 3 with opposite forces at the same time, facilitating the quick separation of the dinner plate 3, and being beneficial to better cleaning the dinner plate 3 in the later stage.
