Description

Technical Field

[0001] This invention provides a suction cup structure that balances internal and external air pressure. It primarily offers a suction cup solution for non-circular or non-approximately circular elastic bases, and also provides a solution for suction cups that adhere too tightly and cannot be removed. This invention is applicable to various elastic, irregularly shaped suction cups, and the structure exhibits improved stability after applying this solution. Background Art

[0002] Existing suction cup structures, when individually elastic, become too tight and difficult to remove. Furthermore, suction cups are ineffective on non-circular or non-approximately circular elastic surfaces.

[0003] There is a need for a suction cup structure that balances internal and external air pressure and can solve the problems mentioned above. Summary of the Invention

[0004] This invention provides a suction cup structure that balances internal and external air pressure. It primarily offers a suction cup solution for non-circular or non-approximately circular elastic bases, and also provides a solution for suction cups that adhere too tightly and cannot be removed. This invention is applicable to various elastic, irregularly shaped suction cups, and the structure exhibits improved stability after applying this solution.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A ring is added to the outer surface of the independent, elastic suction cup. A long through-groove or non-through-groove is provided on the non-circular or non-approximately circular elastic base area.

[0006] The beneficial effects of this utility model are as follows: 1. On the outer surface of the independent, elastic suction cup, there is a ring. The ring structure provides some assistance in removing the suction cup if it is too tightly attached, making it difficult to remove. When the suction is too tight, gently lifting the outer ring can balance the air pressure difference between the inside and outside of the suction cup, making it easy to remove.

[0007] 2. On a non-circular or non-approximately circular elastic base area, there is a long through groove or a non-through groove. The through groove or non-through groove enhances the suction effect of the suction cup on a non-circular or non-approximately circular elastic area. The other side of the long through groove or non-through groove, outside the suction cup, has the same effect as the rim ring on the outer surface of the suction cup described in specification 1.

[0016] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1-3 As shown, this utility model provides a suction cup structure for balancing internal and external air pressure, comprising an elastic suction cup structure 1, a rim ring 2, and a groove 3.

[0018] 1. On the outer surface of the independent, elastic suction cup 1, there is a ring 2. The ring structure helps to remove the suction cup if it is too tightly attached. When it is too tightly attached, gently lifting the outer ring 2 can balance the air pressure difference between the inside and outside of the suction cup, making it easy to remove the suction cup 1.

[0019] 2. On a non-circular or non-approximately circular elastic base area, there is a long through groove or non-through groove 3. The through groove or non-through groove 3 enhances the adsorption effect of the suction cup 1 on the non-circular or non-approximately circular elastic area. On the other side of the long through groove or non-through groove 3, which is not on the suction cup, it has the same effect as the rim ring 2 on the outer surface of the suction cup described in specification 1.

[0020] The present invention has the following features: 1. The suction cups set on the non-circular or non-approximately circular elastic base area adhere more tightly. The through groove or non-through groove set in this application is conducive to the downward pressure of the suction cups set on the non-circular elastic base area, which can better expel the air in the suction cups and make them adhere more tightly.

[0021] Second, the suction cup is easier to remove. Simply lift the outer ring to balance the air pressure difference between the inside and outside of the suction cup, and you can easily remove the suction cup.

Claims

1. A suction cup structure for balancing internal and external air pressure, characterized in that, On the outer surface of the independent, flexible suction cup, there is a ring. On the non-circular or non-near-circular flexible base area, there is a long through groove or non-through groove. This ring groove can make it easier to remove the suction cup in the subsequent process.

2. The suction cup structure for balancing internal and external air pressure according to claim 1, characterized in that, On the flexible base area that is not circular or not nearly circular, there is a long through groove or non-through groove. The through groove or non-through groove provides a breakthrough point for the suction cup to be stuck too tightly and cannot be removed. This breakthrough point can better make the air pressure inside and outside the suction cup equal, thereby removing the suction cup.
