Description
English Translation of:
SUCKING DISK AND VACUUM SUCKER HAVING THE SAME
FIELD
This application relates to the technical field of sucking immobilization, and
particularly to a sucking disk and a vacuum sucker having the sucking disk.
BACKGROUND
A sucking disc device is a tool, which is sucked on an object by employing the
difference between an internal pressure and an external atmospheric pressure, for hanging an
article.
Currently, a vacuum sucker is a common sucking disc device which has been widely
applied in industry and household. The vacuum sucker for household application is mainly to
meet the demand of people for hanging houseware at any time. Since the vacuum sucker is
detachable, it can be used for hanging towels, clothing and so on.
The vacuum sucker typically includes a sucking disc body and a slider pushing
mechanism. The sucking disc body can be sucked on or detached from a wall or other support
bodies by the slider pushing mechanism. The slider pushing mechanism is mainly in a form of
a stepped ramp, and mainly includes a slider, a slider cover, a sucking disc cover and a pin
shaft. The slider is provided with a stepped surface. A connecting end of the sucking disc is
connected to the sucking disc cover through the pin shaft. The slider is slidably connected to
the sucking disc cover, and the pin shaft is laterally provided on the stepped surface of the
slider. The slider cover is covered on an upper surface of the slider.
The slider cover is pushed by a user to move reciprocally, which brings the slider to
move. The stepped surface of the slider is moved with respect to the pin shaft, and in turn the
pin shaft is moved upward or downward perpendicular to a sucking face. When the pin shaft
is moved upward, a vacuum space is formed between the sucking disc body and the support
body, thus the vacuum sucker is immobilized with respect to the support body. When the pin
shaft is moved downward along the stepped surface, the sucking disc body gets close to the
English Translation of:
support body, and the vacuum space between the sucking disc body and the support body is
released, and thus the sucking between the sucking disc body and the support body is
released.
Currently, the sucking face of the sucking disc body in contact with the support body
generally employs a hard rubber. Although the hard rubber has a relatively strong supporting
capability, the sucking force between the sucking surface made of the hard rubber and the
support body with an uneven surface is poor, thus, the application of the vacuum sucker on an
uneven surface environment is limited.
Therefore, in view of the above issue, a technical issue to be addressed presently by
those skilled in the art is to improve the structure of a vacuum sucker in the conventional
technology, which can be applied onto an uneven surface environment.
SUMMARY
An object of the present application is to provide a vacuum sucker which can be
reliably sucked on an uneven surface of a support body.
[0009] To achieve above object, a following technical solution is employed according to the
present application.
A sucking disc, includes a sucking disc body. The sucking disc body has a connecting
portion at an outer side and a sucking surface at an inner side. The sucking disc body includes
a soft rubber layer and a hard rubber layer. The soft rubber layer and the hard rubber layer
together form the sucking surface of the sucking disc body. The hardness of the soft rubber
layer is lower than the hardness of the hard rubber layer.
Compared with a sucking surface formed of a single hard rubber or a sucking surface
formed of a single soft rubber in the conventional technology, the sucking surface of the
sucking disc body herein is formed of the soft rubber layer and the hard rubber layer together.
The hard rubber layer can provide a better support strength required by the sucking disc body
when bearing a load in a sucking state. The surface of the soft rubber layer is softer than the
surface of the hard rubber layer, and when the sucking disc body is in the sucking state, the
soft rubber layer is easily deformed under a suction pressure, thus the soft rubber layer can

the circumferential projection abuts against a corresponding surface of the sucking disc cover.
Optionally, an outside surface of the sucking disc cover is provided with two sliding
rails, and the two sliding rails cooperate with the slider in sliding, and the outside surface of
the sucking disc cover is provided with a boss. The two sliding rails are arranged on a surface
of the boss.
Optionally, the outside surface of the sucking disc cover is further provided with a
hanging slot. An opening of the hanging slot faces outward. When the vacuum sucker is in a
non-sucking state, the slider is located above or below the hanging slot. When the vacuum

DETAILED DESCRIPTION
In view of the technical issue present in the conventional technology that a vacuum
sucker is sucked onto an uneven surface with a poor sucking force, an in-depth research is
conducted herein. Through the research, it has been found that a sucking disc body in the
conventional technology tends to employ a hard rubber to achieve the service strength and the
service life of the sucking disc body. The hard rubber in a range of the hardness value is not
easily deformed. When the hard rubber is in sucking contact with an uneven surface, it is
different to form a sealed space between the hard rubber and the uneven surface, resulting in a
relatively poor sucking force, thus the application of the vacuum sucker in an uneven surface
environment is limited.
Based on the above research, the proposed technical solution herein, in which the
English Translation of:
service life and the strength of the sucking disc body are compromised and a strong sucking
force in the uneven surface environment is achieved, is described in detail below.
For those skilled in the art to better understand the technical solutions of the present
application, the technical solutions are further described in detail hereinafter in conjunction
with the drawings and embodiments.
Reference is made to Figures 1 to 2. Figure 1 is a schematic view showing the
structure of a sucking disc herein. Figure 2 is an exploded view of the sucking disc shown in
Figure 1.
A sucking disc is provided according to the present application, which is mainly
applied to a vacuum sucker. The sucking disc includes a sucking disc body 6. The sucking
disc body 6 is provided with a connecting portion at an outer side, and the specific structure of
the connecting portion will be specifically described below. The sucking disc body 6 has a
sucking surface at an inner side. The sucking disc body 6 includes a soft rubber layer 62 and a
hard rubber layer 61. The soft rubber layer 62 and the hard rubber layer 61 together form the
sucking surface of the sucking disc body 6. The sucking surface described herein refers to a
surface of the vacuum sucker in sucking contact with a support body. Reference may be made
to the conventional technology for the material of the hard rubber layer 61 commonly used in
the sucking disc. The hard rubber layer 61 herein may be a material forming the sucking
surface of the sucking disc body 6 in the conventional technology. Accordingly, the hardness
of the soft rubber layer 62 herein is lower than the hardness of the hard rubber layer 61 and an
adhesion degree of the soft rubber layer 62 herein is higher than an adhesion degree of the
hard rubber layer 61.
Compared with a sucking surface formed of a single hard rubber or a sucking surface
formed of a single soft rubber in the conventional technology, the sucking surface of the
sucking disc body 6 herein is formed of the soft rubber layer 62 and the hard rubber layer 61
together. The hard rubber layer 61 can provide a better support strength required by the
sucking disc body 6 when bearing a load in the sucking state. The surface of the soft rubber
layer 62 is softer than the surface of the hard rubber layer 61. When the sucking disc body 6 is
English Translation of:
in the sucking state, the soft rubber layer 62 is easily deformed under the action of the sucking
pressure, thus the soft rubber layer 62 can better follow a surface of a support body, which
facilitates the sealing of the surface of the support body, increases the sucking capacity of the
sucking disc body 6 in the uneven surface environment, and facilitates the application of the
vacuum sucker in the uneven surface environment, thereby expanding the application scope
of the vacuum sucker.
Herein, the technical solution is further described by taking the sucking disc body 6
applied to the vacuum sucker as an example.
Reference is made to Figure 4, which is an exploded view of the vacuum sucker. The
vacuum sucker includes the sucking disc, a sucking disc cover 4, a slider assembly, and an
elastic component 5. A connecting portion of the sucking disc is a mounting post 63 provided
with a lateral through hole 6a, a mandrel 2 is provided in the lateral through hole 6a, and the
mounting post 63 is positioned to the sucking disc cover 4 by the mandrel 2. Specifically, the
sucking disc cover 4 is provided with two position-limiting blocks 43 to limit an upper
position and a lower position, and the position of the mandrel 2 is limited between the two
position-limiting blocks 43, and the mandrel 2 can be relatively moved in a front-rear
direction. Further, the elastic component 5 is also provided between the sucking disc cover 4
and the sucking disc. The elastic component 5 may be a coil spring, which, apparently, may
also be other forms of elastic component 5.
[0042] The slider assembly includes a slider 3 having a stepped surface and a slider cover 1
covered over the slider 3. The arrangement of the stepped surface may refer to Figure 4, and
the stepped surface has at least two steps for positioning the mandrel 2. When the mandrel 2 is
positioned on the first step, the sucking disc body 6 is in a non-sucking state; and when the
mandrel 2 is positioned on the second step, the sucking disc body 6 is in the sucking state.
[0043] Reference is made to Figures 5, 6 and 7, 8. Figure 5 is a schematic view of a vacuum
sucker herein being in the non-sucking state. Figure 6 is a sectional schematic view taken
along E-E in Figure 5. Figure 7 is a schematic view of the vacuum sucker herein in the
sucking state. Figure 8 is a sectional schematic view taken along F-F in Figure 7. The specific
English Translation of:
operating process of the vacuum sucker herein is as follows.
Figures 5 and 6 are schematic views of the vacuum sucker in the non-sucking state.
When it is required to suck the vacuum sucker on the surface of the support body, the slider
cover 1 is pushed downward, and the slider 3 is also moved along with the slider cover 1, thus
the slider 3 is moved downward. Since the stepped surface of the slider 3 in contact with the
mandrel 2 is gradually raised from bottom to top, the mandrel 2 brings the sucking disc body
6 to gradually move to the left under the abutment action of the stepped surface. Since the
periphery of the sucking disc body 6 abuts against the sucking disc cover 4, a central part of
the sucking disc body 6 is deformed to form a vacuum space, thus the vacuum sucker is
sucked on the surface of the support body.
Reference is made to Figures 7 and 8, when it is required to detach the vacuum
sucker from the object, it simply need to push the slider cover 1 reversely to move the slider 3,
and the mandrel 2 is moved from a high position to a low position of the stepped surface of
the slider 3, meanwhile, the deformed portion at the central part of the sucking disc body 6 is
recovered to an original position by the action of a restoring force of the elastic component 5,
then the sucking disc body 6 is in the non-sucking state.
In the above embodiments, the soft rubber layer 62 of the sucking disc body 6 may
be an annular structure, and the surface of the hard rubber layer 61 is provided with a
mounting groove for fitting the soft rubber layer 62. Further, an outer surface of the soft
rubber layer 62 is not lower than an outer surface of the hard rubber layer 61, that is to say, in
the case that the soft rubber layer 62 is mounted to the hard rubber layer 63, the outer surfaces
of the soft rubber layer 62 and the hard rubber layer 61 are located in a same plane or the
outer surface of the soft rubber layer 62 is slightly higher than the outer surface of the hard
rubber layer 61.
[0047] Thus, the soft rubber layer 62 is arranged uniformly in a circumferential direction of
the sucking disc body 6. When the vacuum sucker is in the sucking state, the soft rubber layer
62 is deformed uniformly, which facilitates a sealing contact with the support body in the
circumferential direction and improves the sucking reliability of the vacuum sucker.
English Translation of:
It can be seen in the description of the sucking operating state of the above vacuum
sucker that, the central part of the vacuum sucker has a relatively large deformation. Thus, the
closer to the central part of the vacuum sucker a position is, the weaker the sealing of the
sucking disc body 6 to a contacting surface of the support body is.
[0049] In view of this, a further improvement is made on the basis of the embodiments
described above according to the present application.
Reference is made to Figure 3, which is a partially enlarged view of a position at
which the soft rubber layer is connected to the hard rubber layer.
In one particular embodiment, the thickness of the annular structure is gradually
increased from outside to inside in a radial direction. It is to be noted that herein the center of
the annular structure is defined as “in ”, correspondingly, another end to which a radius
extends is defined as “out ”.
It should be noted that, the annular structure described herein may have the same
shaped inner surface and outer surface, such as a circular shape, a square shape, etc..
Apparently, the inner surface and the outer surface may also have different shapes. The
schematic structural view, in which the inner surface is in a circular shape, and the outer
surface is in a square shape, is illustrated herein.
The mounting of the soft rubber layer 62 to the hard rubber layer 61 may be
implemented by various manners, for example, by injection molding or press molding. In
order to improve the reliability of the soft rubber layer 62 and the hard rubber layer 61, the
mounting groove on the surface of the hard rubber layer 61 can be designed as a
multi-stepped surface structure, accordingly, the mounting portion of the soft rubber layer 62
may also be a multi-stepped surface. In this way, the soft rubber layer 62 and the hard rubber
layer 61 are formed via the multi-stepped surfaces, thus the positioning reliability of the soft
rubber layer 62 and the hard rubber layer 61 is increased.
When the vacuum sucker is in the sucking state, the central part of the sucking disc
body 6 is deformed inward to form the vacuum space. In the conventional technology, the
periphery of the sucking disc body 6 is generally immobilized to the sucking disc cover 4 by a
English Translation of:
pressing process. In the conventional technology, in the case that the vacuum sucker is used
for a number of times, the sucking disc body 6 and the sucking disc cover 4 are apt to move
with respect to each other at a pressing position. Therefore, on the basis of the above
embodiments, the technical issue, in which the sucking disc body 6 and the sucking disc cover
4 move and deform with respect to each other, is further addressed herein.
Specifically, reference is made to Figures 9, 10, 11, 12. Figure 9 is a schematic view
showing the specific structure of a sucking disc cover herein. Figure 10 is a sectional view of
the sucking disc cover shown in Figure 9. Figure 11 is a schematic view showing the
assembly of the sucking disc cover and the sucking disc. Figure 12 is an enlarged view at
position A in Figure 11.
In a preferred embodiment, an outside surface of the sucking disc body 6 has a
circumferential projection 64 extending rearward, and a corresponding side surface of the
sucking disc cover 4 has a groove 4b for fitting the circumferential projection 64. When the
vacuum sucker is assembled, the circumferential projection of the sucking disc body 6 is
mounted in the groove 4b. In this way, when the central part of the sucking disc body 6 is
deformed, the groove 4b limits the circumferential projection 64 in a certain degree, thus
preventing an outer edge of the sucking disc body 6 from moving inward.
Considering the issue of sealing in the case that the sucking disc and the sucking disc
cover 4 are mounted together, the sucking disc may be further designed as follows. In the
above embodiments, an outer diameter of the outside surface of the sucking disc body 6 is
larger than an outer diameter of the circumferential projection 64. In the case that the sucking
disc is assembled with the sucking disc cover 4, an edge portion 65 located outside the
circumferential projection 64 abuts against a corresponding surface of the sucking disc cover
4. Thus, the sucking disc cover 4 and the sucking disc can form a reliable sealing structure.
[0058] Referring again to Figure 9, an outside surface of the sucking disc cover 4 is
provided with two sliding rails 42 for cooperating with the slider 3 in sliding, and the outside
surface of the sucking disc cover 4 may be provided with a boss 41. The two sliding rails are
arranged on a surface of the boss 41.
English Translation of:
In this embodiment, when the slider 3 is moved back and forth, the slider 3 is in
sliding contact with the boss 41, preventing the slider 3 from being in contact with the
sucking disc cover 4, and reducing rubbing to the surface of the sucking disc cover 4, which
facilitates holding a smooth surface of the sucking disc cover 4 in one aspect, and in another
aspect, reduces the acting force for driving the slider 3 since the slider 3 is in partial contact
with the boss 41, the contact area is relatively small, and the resistance during the sliding
movement is relatively small.
In the above embodiments, the outside surface of the sucking disc cover 4 may be
further provided with a hanging slot 4a, and the hanging slot is also provided with a fastener,
an opening of the hanging slot 4a faces outward. When the vacuum sucker is in the
non-sucking state, the slider 3 is located above or below the hanging slot 4a. When the
vacuum sucker is in the sucking state, the slider 3 is placed at the opening of the hanging slot
Based on the above description of the disclosed embodiments, the person skilled in
the art is capable of carrying out or using the present application. It is obvious for the person
skilled in the art to make many modifications to these embodiments. The general principle
defined herein may be applied to other embodiments without departing from the spirit or
scope of the present application. Therefore, the present application is not limited to the
embodiments illustrated herein, but should be defined by the broadest scope consistent with
the principle and novel features disclosed herein.
