Description

Suction cup

The invention relates to a suction cup.

In daily life, items can be hanged everywhere for the user to take or watch, such as clocks, calendars, paintings, etc., and in order not to damage the structure of the hanging place, the manufacturer has developed a suction cup. It extracts air by pressing the suction cup to generate a vacuum suction force to adsorb on the surface of the object. In this way, the user can hang the object through the suction cup without damaging the surface of the object, and the suction cup can also be used to carry objects that are not easily applied by the object, such as glass.

However, most of the above-mentioned suction cups can only be adsorbed on objects with smooth surfaces, so the use level is greatly limited; and, such suction cups will weaken and fall off at intervals, and cannot maintain a stable suction state for a long time; In order to return the suction cup to the negative pressure state, it is very troublesome to remove the suction cup and then press it again on the surface. Therefore, how to solve the above problem is a lack of improvement for the industry.

Therefore, it is necessary to provide a novel and progressive suction cup to solve the above problems.

The main object of the present invention is to provide a suction cup which can be adsorbed on a generally smooth surface, and can be adsorbed on a rough surface, and when the pressure difference between the chamber of the suction cup and the outside is small, the pressure can be increased without removing the suction cup. Poorly returned to a stable suction state.

To achieve the above object, the present invention provides a suction cup comprising an adsorption body and a suction mechanism. The adsorption body is configured to be adsorbed on a surface, defines a chamber, and is provided with a channel and is provided with a first flange and at least a second flange spaced apart around the chamber, the channel is connected to the chamber, a first flange is located on an outer side of the at least one second flange, each of the second flanges is inclined toward the first flange; the air suction mechanism is disposed on the adsorption body, and the air suction mechanism communicates with the cavity via the passage The chamber is externally operated to evacuate the chamber, thereby placing the chamber in a negative pressure state.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Please refer to FIG. 1 to FIG. 8 , which illustrate a preferred embodiment of the present invention. The suction cup of the present invention comprises an adsorption body 1 and a suction mechanism 4 .

The adsorption body 1 is configured to be adsorbed on a surface 81 and defines a chamber 13. Further, the adsorption body 1 is provided with a passage 14 and is provided with a first flange 2 and at least one spaced apart and surrounding the chamber 13. Second flange 3. The passage 14 is connected to the chamber 13 , and the first flange 2 is located on the outer side of the at least one second flange 3 , and each of the second flanges 3 is inclined toward the first flange 2 . The air suction mechanism 4 is disposed on the adsorption body 1 , and the air suction mechanism 4 communicates with the chamber 13 via the channel 14 and is externally operated to evacuate the chamber 13 , thereby causing the chamber 13 to be under negative pressure. status.

When the suction cup is adsorbed on the surface 81, the first flange 2 and the at least one second flange 3 can form a plurality of retaining walls (in the embodiment, the number of the at least one second flange 3 is two) to block The outside air flows into the chamber 13, thereby ensuring that the chamber 13 can be stably in a negative pressure state. Wherein, because each of the second flanges 3 is designed to extend obliquely toward the outside, the force generated by the pressure difference between the inside and the outside during the suction is pressed against the second flanges 3, so that the second flanges 3 can be further improved. Further deformed to adhere to the surface 81, reducing voids, so the suction cup can be adsorbed to the rougher surface 81, such as but not limited to: walls, lychee structures, and the like.

More specifically, the adsorption body 1 is substantially circular. The adsorption body 1 is further provided with a base portion 11 and an adsorption portion 12. The base portion 11 and the adsorption portion 12 surround the chamber 13. The adsorption portion 12 is provided. The first flange 2 and each of the second flanges 3 are laterally protruded from the adsorption portion 12 to be adhered to the surface 81 and obliquely to the base portion 11. Wherein, the adsorption portion 12 is inclined toward the surface 81, thereby reducing the contact area with the surface 81, so that stress concentrates on the first flange 2 and each of the second flanges 3 and is more easily deformed to closely fit. This surface 81.

More specifically, the size of the first flange 2 is larger than the size of each of the second flanges 3, so that the first flange 2 is more resistant to collisions from the lateral direction during the adsorption process, and the side can be avoided. The situation in which the force is deformed and lifted to cause the outside air to flow into the chamber 13 occurs. However, since the first flange 2 can be positively deformed and attached to the surface 81 to block the gas from entering the chamber 13 in the forward direction, in this embodiment, the cross-sectional view of the adsorption portion 12 is used. The first flange 2 and the at least one second flange 3 are arranged in a zigzag manner and are hierarchically arranged. The first flange 2 protrudes from the at least one second flange 3 so that the first one during the adsorption process The flange 2 can have a large stress to assist in its deformation.

The structure of the adsorption body 1 can be clearly understood from the above, and then the suction mechanism 4 will be further described. The pumping mechanism 4 includes a base body 41 and a piston set 42. The base body 41 is positioned on the suction body 1 and communicates with the passage 14. The piston set 42 is movably inserted into the base body 41 along a pressing direction 92. The piston group 42 is pressed against the outside by the outside in the pressing direction 92 to evacuate the chamber 13. As the pumping progresses, the pressure difference between the chamber 13 and the outside is increased. Therefore, when it is found that the pressure difference is insufficient, the user only needs to press the piston set 42 again, and it is no longer necessary to remove the entire suction cup and reinstall it on the surface 81.

It is worth mentioning that the greater the pressure difference between the chamber 13 and the outside, the more the piston group 42 remains buried in the base 41, the shorter the stroke that the piston set 42 can move, when a preset is reached. When the pressure is different, the negative pressure suction generated by the chamber 13 not only enables the suction cup to be closely adhered to the surface 81, but also closely attracts the piston group 42. At this time, the stroke of the piston group 42 is zero. Press again. On the contrary, when the pressure difference between the chamber 13 and the outside is gradually reduced, the generated negative pressure suction force is also reduced, and the portion of the piston group 42 protruding from the base body 41 is gradually increased.

After understanding the operation of the air suction mechanism 4, preferably, the piston group 42 is provided with a warning unit 5 at a predetermined position in the pressing direction 92, and the predetermined position corresponds to a specific pressure difference to notify the user of the cavity. The pressure difference of the chamber 13 changes or is insufficient, reminding the user that the chamber 13 needs to be pumped again to increase the adsorption force. In the present embodiment, the warning unit 5 is looped on the piston set 42, and the color of the warning unit 5 is different from the color of the piston set 42, and the user can quickly know by visual inspection.

Alternatively, an ear piece 72 is provided on the suction body 1 for external pick-up to facilitate the flow of outside air into the chamber 13, so that the suction cup can be quickly removed from the surface 81. In another preferred embodiment, a plurality of grooves 111 are recessed in the base portion 11. The at least one groove 111 communicates with the channel 14 and is secured in the chamber 13 when a portion of the surface 81 abuts against the base portion 11. The gas can also flow into the channel 14 via the at least one trench 111. More preferably, a filter 141 is positioned in the passage 14 such that fine debris in the chamber 13 is not drawn into the passage 14 or the base 41 during pumping to ensure the passage 14 and the The pumping mechanism 4 is unblocked and can protect the piston group 42 from moving smoothly.

The suction cup further includes a body 6 disposed on the suction body 1 and covering the portion of the air suction mechanism 4, and the insertion hole 61 is disposed in the base body 6. The insertion hole 61 is provided for The rod 82 is inserted to connect the seat body 6. Wherein, the hardness of the seat body 6 is greater than the hardness of the adsorption body 1, and the rod member 82 can be surely restrained and subjected to an unintended impact. In addition, a screw hole 63 is formed in the base body 6. The screw hole 63 communicates with the insertion hole 61. The screw hole 63 is screwed to a pressing member 93 to press the rod member 82 to further lift the hole. The degree of coupling and stability of the rod member 82 and the seat body 6 make the rod member 82 less likely to be detached from the seat body 6.

The design of the insertion hole 61 allows the suction cup to have a more diverse application. For example, when camping out, the suction cup is attracted to an appropriate plane, and the rod 82 of the support plate is inserted into the insertion hole 61 to form a simple hanging table for use. Alternatively, the suction cups may be connected to each other through the rod member 82 to form a simple towel rack. There are many ways to use, users can freely combine according to different needs, very simple and convenient.

In the embodiment, the opening direction 91 of the insertion hole 61 is perpendicular to the pressing direction 92, and the hand can ergonomically hold the seat body 6 during the pressing of the piston set 42. In more detail, the insertion hole 61 is higher than the base 41 along the opening of the insertion hole 61. In other words, a difference is generated between the rod 82 and the piston set 42. The rod 82 can be The base body 6 is inserted deeper without interfering with the base body 41. More specifically, in the opening direction 91 and the pressing direction 92 of the insertion hole 61, the height of the seat body 6 is twice the height of the adsorption body 1, and a suitable ratio is used. .

Preferably, the suction cup further comprises a hanging member 71. The base body 6 is further provided with at least one set of connecting portions 62. The hanging member 71 can be selectively assembled to the connecting portion 62 for hanging. object. In this embodiment, the number of the at least one connecting portion 62 is two, one of the connecting portions 62 is located on the extending line of the pressing direction 92, and the other connecting portion 62 is located at the opening direction 91 of the insertion hole 61. On the extension line. The splicing portion 62 is embedded in the slats, and the slings 71 are positioned on the pedestal 6 by means of embedding, which facilitates quick disassembly and assembly.

It should be noted that the base portion 11 and the adsorption portion 12 are integrally formed of a rubber material, and can be mass-produced quickly. Preferably, the color of the seat body 6, the hanging member 71 and the absorbing body 1 belong to the same color system, so that the overall appearance of the suction cup has a uniform color matching for use in different environments, and is also better recognized and used. . Alternatively, the color of the air suction mechanism 4 is different from the color of the base body 6 and the color of the suction body 1, so that the user can quickly find out the action of the air suction mechanism 4 for pumping.

In summary, the suction cup of the present invention adopts a suction mechanism to pump the chamber to generate a negative pressure difference. Therefore, when the pressure difference is insufficient when suspending, only the piston group needs to be pressed, and the entire suction cup and the hanging object are not required. It is very convenient to remove and reinstall. Moreover, the design of the second flange inclined toward the first flange can ensure that the first and second flanges can positively close the chamber when the relative deformation occurs, and the outside air does not easily flow into the chamber to ensure the pressure difference. Stable adsorption. In addition, a warning unit is provided at a predetermined position on the piston group, so that the pressure difference between the chamber and the outside can be known by the user directly.
