Description

Technical Field

[0001] The utility model relates to an ultra-thin suction cup. Background Art

[0002] At present, in some common daily products, such as storage trays, condiment trays, clothes hangers, etc., in order to save floor space, they are usually fixed in a wall-mounted form, and among them, using a suction cup to adsorb for wall mounting is a fixed method with relatively high cost performance and simple disassembly and assembly. However, the common suction cup products on the market at present often have a relatively high height, that is, the ratio of the adsorption area of the suction cup to the total height of the suction cup is often less than 2:1. This results in that when users use the suction cup products to adsorb and fix items, either a large number of suction cups with small adsorption areas are used for fixation, resulting in increased costs and a cumbersome installation process; or a small number of suction cups with large adsorption areas are used for fixation, but this will cause a large gap between the fixed item and the adsorption surface, and since the load is far from the adsorption surface, the tipping moment received by the suction cup becomes larger, which is not conducive to stable adsorption.

[0003] Therefore, how to overcome the above-mentioned existing defects has become an important issue that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0004] The utility model overcomes the above technical deficiencies and provides an ultra-thin suction cup.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An ultra-thin suction cup, comprising an outer shell 1 and a suction cup 2 stacked up and down. The upper surface of the suction cup 2 exposes a skeleton 21. The skeleton 21 and the outer shell 1 are connected together through a nested snap structure 3. The lower part of the outer shell 1 is provided with a cover body 11 for covering the suction cup 2. The upper part of the outer shell 1 is provided with a connecting boss 12 for an external item to be stuck thereon. When the suction cup 2 is in place in contact with the adsorption surface, the diameter of the contact area is D. The outer contour diameter of the cover body 11 is 1.01D to 1.2D. After the suction cup 2 is in place in contact with the adsorption surface, the total height is H. The total height of the outer shell 1 is also H. After the ultra-thin suction cup is in place in contact with the adsorption surface, the total height is 1.01H to 1.2H, D:H≥3:1, and H≤10mm.

[0007] Preferably, the suction cup 2 is a semi-packaged rubber suction cup. The suction cup 2 further comprises a suction cup main body 22. The suction cup main body 22 is injection molded with the skeleton 21 as an insert. The suction cup main body 22 wraps the upper surface edge, side surface and bottom surface of the skeleton 21. Except for the edge area, the upper surface of the skeleton 21 is exposed on the suction cup main body 22. The average wall thickness of the suction cup 2 is A, and D:A≥12:1.

[0008] Preferably, the nested buckle structure 3 includes a plurality of first buckle bodies 31 protruding upward from the upper surface of the skeleton 21. A first convex buckle 32 extending outward is provided at the top of the first buckle body 31. A plurality of second buckle bodies 33 corresponding to the first buckle bodies 31 one by one and protruding downward are provided on the outer shell 1. A second convex buckle 34 extending inward is provided at the bottom of the second buckle body 33. A first accommodation space 35 for the second convex buckle 34 to snap into is formed between the first convex buckle 32 and the upper surface of the skeleton 21. A second accommodation space 36 for the first convex buckle 32 to snap into is formed between the second convex buckle 34 and the outer shell 1. A first guiding inclined surface 37 is provided on the upper surface of the first convex buckle 32, and a second guiding inclined surface 38 is provided on the lower surface of the second convex buckle 34. The total height of the first buckle body 31, which is the sum of the height of the first convex buckle 32 and the first accommodation space 35, is 0.5H. The total height of the second buckle body 33, which is the sum of the height of the second convex buckle 34 and the second accommodation space 36, is 0.5H. The heights of the first convex buckle 32 and the second convex buckle 34 are the same, being 0.24H - 0.25H.

[0009] Preferably, a protruding portion 13 is provided on the upper part of the outer shell 1. The second buckle body 33 extends downward from the upper surface of the protruding portion 13. A plurality of clearance holes 14 for exposing the top ends of the first buckle bodies 31 are provided on the protruding portion 13. The connecting boss 12 is provided on the side surface of the protruding portion 13.

[0010] Preferably, a plurality of exhaust ribs 15 for abutting against the suction cup 2 to facilitate exhaust are provided below the cover body 11.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The ultra-thin suction cup in this case includes two parts: a housing and a suction cup. Since the number of parts is much smaller than that of common suction cup products on the market, the ultra-thin suction cup in this case can have a smaller height. Moreover, the housing and the suction cup are connected together through a nested snap structure, which enables the housing and the suction cup to have a coincidence degree of more than 83% in the height direction after the ultra-thin suction cup fits in place with the adsorption surface. That is, the height of both the housing and the suction cup is H, while the total height of the ultra-thin suction cup after fitting in place is 1.01H to 1.2H. Thus, under the same adsorption area, the height of the ultra-thin suction cup in this case can be much lower than that of market products, and the ratio D:H of the adsorption area to the height of the suction cup can be greater than or equal to 3:1. Specifically, the height of the suction cup in this case can be less than or equal to 10 mm, which can greatly reduce the gap between the fixed product and the adsorption surface, and at the same time enable the suction cup to have better stress conditions. In addition, a connecting boss for external items to be stuck on is provided on the housing of this case, and the connecting boss is set within the height range of the housing, which can further ensure that the height will not be further increased when the ultra-thin suction cup in this case is connected to external items. Additionally, after the ultra-thin suction cup in this case fits in place, the suction cup will be covered by a cover body, which can effectively improve the aesthetics of the ultra-thin suction cup in this case.

[0024] The features of the present utility model and other related features are further described in detail through the following embodiments for the understanding of those skilled in the same industry:

[0025] As shown Figures 1 to 8 in the figure, a super-thin suction cup includes a housing 1 and a suction cup 2 stacked up and down. A framework 21 is exposed on the upper surface of the suction cup 2. The framework 21 and the housing 1 are connected together through a nested snap structure 3. A cover 11 for covering the suction cup 2 is provided at the lower part of the housing 1. A connecting boss 12 for an external article to be stuck thereon is provided at the upper part of the housing 1. When the suction cup 2 is in place in contact with the adsorption surface, the diameter of the contact area is D. The outer contour diameter of the cover 11 is 1.01D to 1.2D. After the suction cup 2 is in place in contact with the adsorption surface, the total height is H, and the total height of the housing 1 is also H. The total height of the super-thin suction cup after being in place in contact with the adsorption surface is 1.01H to 1.2H. D:H≥3:1, and H≤10 mm.

[0026] As described above, the super-thin suction cup in this case includes two parts, namely the housing 1 and the suction cup 2. Since the number of parts is much smaller than that of common suction cup products on the market, the super-thin suction cup in this case can have a smaller height. Moreover, the housing 1 and the suction cup 2 are connected together through a nested snap structure 3, which enables the super-thin suction cup in this case to have a coincidence degree of more than 83% in the height direction after being in place in contact with the adsorption surface, that is, the heights of both the housing 1 and the suction cup 2 are H, while the total height of the super-thin suction cup after being in place is 1.01H to 1.2H. Thus, under the same adsorption area, the height of the super-thin suction cup in this case can be much lower than that of market products, and the ratio D:H of the adsorption area to the height of the suction cup 2 can be greater than or equal to 3:1. Specifically, the height of the suction cup 2 in this case can be less than or equal to 10 mm, which can greatly reduce the gap between the fixed product and the adsorption surface, and at the same time enable the suction cup 2 to have better stress conditions. Moreover, a connecting boss 12 for an external article to be stuck thereon is provided on the housing 1 of this case. The connecting boss 12 is arranged within the height range of the housing 1, which can further ensure that the height will not be further increased when the super-thin suction cup in this case is connected to an external article. In addition, after the super-thin suction cup in this case is in place, the suction cup 2 will be covered by the cover 11, which can effectively improve the aesthetics of the super-thin suction cup in this case.

[0027] As shown Figures 2 to 8 in the figure, preferably, the suction cup 2 is a semi-encapsulated rubber suction cup. The suction cup 2 further includes a suction cup main body 22. The suction cup main body 22 is injection molded with the framework 21 as an insert. The suction cup main body 22 wraps the upper surface edge, side surface and bottom surface of the framework 21. Except for the edge area, the upper surface of the framework 21 is exposed on the suction cup main body 22. The average wall thickness of the suction cup 2 is A, and D:A≥12:1.

[0028] The commonly seen rubber-coated suction cups on the market increase the adsorption performance of the suction cups by setting a skeleton inside the suction cups. However, in such rubber-coated suction cups, the main body of the suction cup often completely wraps the skeleton inside, which also results in the wall thickness of such rubber-coated suction cups being much thicker than that of ordinary injection-molded suction cups without a skeleton.

[0029] As described above, the suction cup 2 in this case includes a skeleton 21 and a suction cup main body 22 that wraps the skeleton 21. Moreover, the suction cup main body 22 only wraps the upper surface edge, side surface, and bottom surface of the skeleton 21, and most of the upper surface of the skeleton 21 is exposed. In this way, the overall wall thickness of the suction cup 2 in this case can be greatly reduced, so that the ratio of the contact area to the average wall thickness can be greater than or equal to 12:1, which can further ensure that the suction cup 2 in this case can have a smaller height.

[0030] As Figures 3 to 8 shown, preferably, the nested snap structure 3 includes a plurality of first snap main bodies 31 that protrude upward on the upper surface of the skeleton 21. The top of the first snap main body 31 is provided with a first convex buckle 32 that extends outward. The housing 1 is provided with a plurality of second snap main bodies 33 that protrude downward and correspond to the first snap main bodies 31 one by one. The bottom of the second snap main body 33 is provided with a second convex buckle 34 that extends inward. A first accommodation space 35 for the second convex buckle 34 to snap into is formed between the first convex buckle 32 and the upper surface of the skeleton 21. A second accommodation space 36 for the first convex buckle 32 to snap into is formed between the second convex buckle 34 and the housing 1. The upper surface of the first convex buckle 32 is provided with a first guiding inclined surface 37, and the lower surface of the second convex buckle 34 is provided with a second guiding inclined surface 38. The sum of the height of the first convex buckle 32 and the first accommodation space 35, that is, the total height of the first snap main body 31, is 0.5H. The sum of the height of the second convex buckle 34 and the second accommodation space 36, that is, the total height of the second snap main body 33, is 0.5H. The heights of the first convex buckle 32 and the second convex buckle 34 are the same, which is 0.24H - 0.25H.

[0031] As described above, the nested snap structure 3 of this case includes a first snap main body 31 correspondingly arranged on the skeleton 21 and a second snap main body 33 arranged on the outer shell 1. A first convex buckle 32 is further arranged on the first snap main body 31. Correspondingly, a second convex buckle 34 is also arranged on the second snap main body 33. In addition, a first accommodation space 35 for the second convex buckle 34 to snap into is formed between the first convex buckle 32 and the skeleton 21. Correspondingly, a second accommodation space 36 for the first convex buckle 32 to snap into is also formed between the second convex buckle 34 and the outer shell 1. Moreover, the heights of both the first snap main body 31 and the second snap main body 33 are 0.5H, and the heights of the first convex buckle 32 and the second convex buckle 34 are between 0.24H and 0.25H. In this way, after the outer shell 1 and the skeleton 21 are docked through the nested snap structure 3, the snap structures on the outer shell 1 and the skeleton 21 can be nested with each other, so that after the outer shell 1 and the skeleton 21 are connected, there is a very high degree of coincidence in the height direction, which can effectively ensure that the ultra-thin suction cup of this case can have a smaller height.

[0032] As Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 Preferably, a convex portion 13 is provided on the upper part of the outer shell 1. The second snap main body 33 extends downward from the upper surface of the convex portion 13. A plurality of clearance holes 14 for exposing the top end of the first snap main body 31 are provided on the convex portion 13. The connecting boss 12 is arranged on the side surface of the convex portion 13.

[0033] As described above, by providing the convex portion 13, the connecting boss 12 can be arranged on the side surface, thereby avoiding increasing the height of the ultra-thin suction cup due to the existence of the connecting boss 12. In addition, by providing the clearance holes 14 on the convex portion 13, the degree of coincidence of the outer shell 1 and the skeleton 21 in the height direction can be further improved, thereby reducing the height of the ultra-thin suction cup.

[0034] Specifically, the height of the convex portion 13 is 0.3H.

[0035] As Figure 3 As shown, preferably, a plurality of exhaust ribs 15 for abutting against the suction cup 2 to facilitate exhaust are provided below the cover body 11. In this way, when the ultra-thin suction cup of this case is attached to the adsorption surface, the air between the suction cup 2 and the adsorption surface can be better exhausted through pressing the outer shell 1 by means of the exhaust ribs 15 to form a negative pressure environment, thereby ensuring the reliability of the adsorption of the ultra-thin suction cup of this case.

[0036] As Figures 3 to 4As shown, preferably, a plurality of through holes 211 are provided on the skeleton 21, and the through holes 211 are filled with the suction cup body 22. In this way, without increasing the wall thickness and the wrapping range of the suction cup body 22, the connection between the skeleton 21 and the suction cup body 22 can be made closer, thereby ensuring the reliability of the connection between the two.

[0037] Specifically, the through holes 211 are distributed in a circumferential and radial array along the center of the skeleton 21. In this way, the connection force between the skeleton 21 and the suction cup body 22 can be ensured to be uniform, and the local separation between the skeleton 21 and the suction cup body 22 can be avoided.

[0038] As Figure 4 shown, preferably, a plurality of hollow slots are provided on the edge of the skeleton 21, which are circumferentially distributed and radially extend inward from the edge. In this way, when the suction cup 2 is deformed in contact with the adsorption surface, the edge of the skeleton 21 can generate a deformation space through the opening and closing of the hollow slots, and the driving force for the suction cup 2 to break away from the contact due to the internal stress generated by the deformation of the skeleton 21 itself after the suction cup 2 is in place can be avoided.

[0039] As Figure 4 shown, preferably, the hollow slots include a cross-shaped hollow slot 212 and a T-shaped hollow slot 213, and the cross-shaped hollow slot 212 and the T-shaped hollow slot 213 are distributed at intervals.

[0040] As described above, the cross-shaped hollow slot 212 can generate a larger deformation space compared with the T-shaped hollow slot 213, and the setting of the T-shaped hollow slot 213 can reduce the influence on the strength of the skeleton 21 itself. By arranging the cross-shaped hollow slot 212 and the T-shaped hollow slot 213 at intervals, the deformation amount of the skeleton 21 can be increased while reducing the influence on the strength of the skeleton 21.

[0041] As described above, the present case protects an ultra-thin suction cup, and all technical solutions that are the same as or similar to those of the present case should be regarded as falling within the protection scope of the present case.
