Suction cup structure and its body

This creation is related to the structure of the suction cup, especially a suction cup structure and its cushion body.

According to the conventional suction cup structure, there is a soft cushion body, usually a rubber product, and an extraction portion is disposed at a central position of the cushion body, and a pressing member is disposed above the cushion body. The suction cup is used by attaching the cushion body to a smooth surface, controlling the pressing member to be pressed on the cushion body through a control member, and simultaneously extracting the extraction portion to move upward to raise the center of the cushion body. Part. At this time, since the pad body is pressed to form an airtight state, the pad body is deformed by extraction to form a vacuum space, thereby generating a strong suction force to fix the suction cup to the wall surface.
However, if the above-mentioned vacuum space is invaded by air, the vacuum state is destroyed and the suction force is lost, so that the suction cup loses the effect of being fixed to the smooth surface, and therefore the pressing ability of the pressing member of the suction cup to the cushion body is important. However, the pad body 6 is made of a soft material and has elastic deformation ability. When the pressing member 7 is controlled and pressed onto the pad body 6, as shown in FIG. 7, first, the pressing force is applied to the pad body 6. Absorbing and weakening, on the other hand, since the pressing member 7 is usually a thin shell and is pressed on the mat body 6 in a point contact type, the contact area is small, and the cushion body 6 is extracted by being pressed. The deformation in the center direction is caused, resulting in a decrease in the airtightness of the portion. In addition, due to the dimensional accuracy of the product components, it is difficult for the pressing member 7 to uniformly apply a pressing force to the cushion body 6, resulting in a poor airtightness of the portion subjected to the pressure, which is easily exposed to the outside air. Intrusion breaks the vacuum state, and the holding time for the suction cup to adhere to the smooth surface is lowered.
In view of this, how to improve the above problems is the primary issue that the creative office wants to solve.

Referring to Figures 1 and 2, there is shown a first embodiment of a pad structure of a suction cup provided by the present invention, which has a disk-shaped body 1 made of a soft material, such as rubber, and the body 1 has a shaft surface 11 for pressing the pressing member of the suction cup. The body 1 is integrally provided with an annular pressure receiving block 2, the pressure receiving block 2 is fixedly connected to the body 1, and the pressure receiving block 2 is uniformly rigid, for example, an annular flat plate made of metal material, and In this embodiment, the pressure receiving block 2 is integrally fixed to the shaft surface 11 such that the shaft surface 11 defines an annular hard pressure receiving region 12 for pressing the pressing member of the suction cup. The body 1 is formed with a pressure receiving portion 15 located below the hard pressure receiving region 12, and the remaining portion is formed as a center portion 13. Further, the main body 1 is provided with an extracting portion 14 at the center portion 13. After the mat body is configured to constitute the suction cup structure, the extracting portion 14 is actuated by the control to deform the central portion 13 to generate suction force.
The figure shown in Fig. 3 is a second embodiment of the pad structure of the suction cup provided by the creation. The difference between this embodiment and the above-described first embodiment lies in the position at which the pressure receiving block 2 is disposed. As shown in the figure, the pressure receiving block 2 is integrally embedded in the interior of the body 1. Although the shape of the cushion body still has a rubber disc shape, the body 1 is embedded on the shaft surface 11 For the pressure block 2, a ring-shaped hard pressure receiving region 12 is defined to be pressed by the pressing member for the suction cup.
Next, the present invention further provides a suction cup structure composed of the above-mentioned pad body, as shown in FIGS. 4 and 5, which comprises a pad body, a pressing member 4 and a control member 5, wherein the pad body is as before The disk has a disc-shaped body 3 made of a soft material, such as rubber, and the top surface of the body 3 is defined as an axial surface 31 for pressing the pressing member 4. The body 3 is integrally provided with an annular pressure receiving block 32. The pressure receiving block 32 has a uniform hard shape, for example, an annular flat plate made of a metal material. The position of the pressure receiving block 32 is as shown in the two embodiments of the pad body, and may be integrally provided on the shaft surface 31 or integrally embedded in the body 3 by the above two methods. The axial surface 31 defines an annular hardened region 33 formed therein. The body 3 is formed with a pressure receiving portion 36 located below the hard pressure receiving region 33, and the remaining portion is formed as a central portion 34.
The main body 3 is provided with an extracting portion 35 in the central portion 34. The extracting portion 35 is provided with a base 351 embedded in the central portion 34, and a column 352 is erected from the base 351 and protruded. The body 3 is out. A screw segment 353 is provided on the outer circumference of the cylinder 352. The pressing member 4 is superposed on the mat body, and the pressing member 4 is provided with a through hole 41 corresponding to the extracting portion 35, while the cylinder 352 of the extracting portion 35 passes through the pressing member 4. The pressing member 4 has an annular pressing portion 42 so as to be superposed on the axial surface 31 of the cushion body. Further, the pressing portion 42 of the pressing member 4 is stacked on the hard pressed region 33.
The control member 5 is disposed on the pressing member 4 and connected to the extraction portion 35. In the embodiment, the control member 5 is provided with a through hole 51 and screwed onto the thread segment 353 of the cylinder 352 of the extraction portion 35. On the other hand, the control member 5 is blocked from the hole edge of the through hole 41 of the pressing member 4. Further, a gasket 52 is disposed between the control member 5 and the hole edge of the through hole 41.
With the above structure and configuration, since the control member 5 blocks the through hole 41, a downward pressing force is generated when the control member 5 is rotated, and as shown in FIG. 6, the force is pressed against the pressing member 4. Further pressed onto the axial surface 31 of the mat, it is further noted that the pressed member 4 is pressed against the hard pressed region 33 on the axial surface 31. Next, the hard pressed region 33 applies this pressing force to the pressed portion 36 of the body. As the control member 5 continues to rotate, since the control member 5 blocks the through hole 41, thereby forming an opposite fixed end, the extraction portion 35 will be pulled by the control member 5 to be displaced upward, so that the body The central portion 34 of the 3 is lifted to deform, thereby creating a vacuum space V which forms the source of suction for the suction cup.
In summary, by the pressure block 32 being a rigid and uniform flat plate, the pressing force applied thereto can be evenly distributed, so that the pressure on the hard pressed region 33 is equalized, and thus the pair is placed thereon. The pressure receiving portion 36 of the lower body 3 forms a surface contact type of pressing type, which increases the contact area between the pad body and the smooth surface; on the other hand, the pressure receiving block 32 is hard and is fixed to the pressure receiving portion 36. Integrally, the amount of deformation of the pressure receiving portion 36 is greatly limited, thereby maintaining a wide contact area between the pad body and the smooth surface. All of the above characteristics can maintain the airtightness of the height of the pad body, and thereby prolong the holding time of the suction cup on the smooth surface.
However, the disclosure of the above embodiments is intended to illustrate the present invention and is not intended to limit the present invention, so the replacement of equivalent elements should still be within the scope of this creation.
In summary, it can be made clear to the skilled person that the creation can achieve the aforementioned objectives, and it has already met the requirements of the Patent Law and submitted an application according to law.
