Description

TECHNICAL FIELD

[0001] The utility model relates to a suction cup, especially a vacuum suction cup and a wall type commodity shelf assembly installed by the vacuum suction cup. BACKGROUND

[0002] The wall type commodity shelf is a practical furniture for storage or decoration by using wall space, which is suitable for small-sized houses, kitchens, bathrooms, living rooms and other scenes.

[0003] The wall type commodity shelf has a hole-free installation mode, including strong glue sticking and vacuum suction cup adsorption.

[0004] As shown in the accompanying drawings, a vacuum suction cup includes a suction cup body made of rubber or other flexible materials, a suction cup skeleton and a suction cup cover made of metal or other rigid materials. Figure 1 The outer threaded rod on the suction cup skeleton is locked with the inner threaded hole on the wall type commodity shelf or locked by the nut after penetrating the through hole on the wall type commodity shelf, so as to install the vacuum suction cup on the wall type commodity shelf.

[0005] However, as shown in the drawings, the wall type commodity shelf is installed on the wall (such as ceramic tile, glass, smooth metal, etc.) by the vacuum suction cup. Figure 2 The gap S is easily reserved between the wall type commodity shelf and the wall, so that when the heavy object is put into the wall type commodity shelf, the vertical support force is provided by the fixed point (vacuum suction point), and the horizontal pulling force of the fixed point is required to resist the moment generated by the gravity to prevent the wall type commodity shelf from overturning.

[0006] Therefore, the applicant proposes the utility model. SUMMARY

[0007] The utility model aims at solving the above-mentioned problems of the prior art and provides a vacuum suction cup.

[0008] In order to achieve the above-mentioned purpose, the utility model discloses a vacuum suction cup, which includes a suction cup body made of rubber or other flexible materials, a suction cup skeleton and a suction cup cover made of metal or other rigid materials.

[0009] One end of the suction disc skeleton is embedded into the suction disc body, and the other end forms an outwardly extending externally threaded rod portion and passes through a through hole one of the suction disc cover, and the suction disc cover covers the suction disc body;

[0010] The center lines of the suction disc skeleton, the suction disc body and the suction disc cover are collinear;

[0011] The end surface of the suction disc cover away from the suction disc body is a plane and is perpendicular to the externally threaded rod portion of the suction disc skeleton;

[0012] A reinforcing plate made of metal or other rigid material is provided on the outer side of the suction disc cover, the reinforcing plate is provided with a through hole two, and the bottom end of the reinforcing plate forms a bending portion;

[0013] The externally threaded rod portion of the suction disc skeleton passes through the through hole two of the reinforcing plate, and when the vacuum suction disc is attached to the wall, the reinforcing plate is always in abutment with the plane of the suction disc cover, and the bending portion of the reinforcing plate is always in abutment with the wall.

[0014] In actual use, the above-mentioned vacuum suction disc can be fixed and installed on the wall type shelf in the following ways: the externally threaded rod portion is screwed into the internally threaded hole pre-provided on the wall type shelf, or the externally threaded rod portion passes through the through hole pre-provided on the wall type shelf and is locked by a nut / screw, or the reinforcing plate is welded to the wall type shelf and then locked by a nut / screw. Then, the wall type shelf can be attached to the wall by the vacuum suction disc, and the bending portion of the reinforcing plate is always in abutment with the wall.

[0015] When a heavy object is placed in the wall type shelf attached to the wall, the wall type shelf tends to overturn away from the wall, and the reinforcing plate generates stress due to deformation. At this time, the wall provides vertical support force through the fixed point (vacuum suction attachment point), and also provides horizontal pulling force through the fixed point to resist part of the moment generated by gravity, and the remaining part of the horizontal moment is offset by the stress of the reinforcing plate, that is, the lateral pulling force of the fixed point is reduced, thereby avoiding damage to the vacuum state of the fixed point to the greatest extent, reducing the risk of falling of the vacuum suction disc, and improving the carrying capacity of the wall type shelf.

[0016] Preferably, in the structure of the above-mentioned vacuum suction disc, the end surface of the suction disc skeleton located in the suction disc body is preferably a concave curved surface, and the curvature of the curved surface is the same as or close to that of the suction disc body.

[0017] In the above-mentioned preferred technical solution, the suction disc skeleton located in the suction disc body has relatively smaller constraint on the deformation of the suction disc body, that is, the suction disc body is more easily deformed during the process of pressing the vacuum suction disc to remove the air between the suction disc body and the wall, and the pressing is also more labor-saving.

[0018] Preferably, the vacuum chuck further comprises a screw cap made of metal or other rigid material, which is matched with the outer threaded rod of the chuck skeleton, and the chuck body, the chuck surface cover and the reinforcing plate are tightly attached to each other in the axial direction of the outer threaded rod by screwing the screw cap.

[0019] In the preferred technical solution, the screw cap is matched with the outer threaded rod of the chuck skeleton, and the vacuum chuck has more complete components, and does not need to be separately configured with a nut / screw cap when being installed with the wall-mounted shelf.

[0020] In addition, the utility model further provides a wall-mounted shelf assembly which comprises the above-mentioned vacuum chuck.

[0021] Compared with the prior art, the vacuum chuck and the wall-mounted shelf assembly have the following technical effects:

[0022] The wall-mounted shelf is installed on the wall through the vacuum chuck, and the stress of the reinforcing plate can resist part of the horizontal moment generated by gravity, so as to reduce the lateral tension of the fixing point (vacuum chuck adsorption point), thereby avoiding the destruction of the vacuum state of the fixing point to the greatest extent, reducing the risk of falling of the vacuum chuck, and improving the carrying capacity of the wall-mounted shelf.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0032] like Figure 3 As shown, as one embodiment of the present utility model, the vacuum suction cup provided in this embodiment includes a suction cup body 1 made of rubber or other flexible material, and a suction cup skeleton 2, a suction cup cover 3, and a hand-tightening nut 4 made of metal or other rigid material; the suction cup cover 3 is provided with a through hole 3-1;

[0033] Wherein, one end of the suction cup frame 2 is embedded into the suction cup body 1, and the other end forms an outwardly extending external threaded rod 2-1 that passes through the through hole 3-1 of the suction cup cover 3, and the suction cup cover 3 covers the suction cup body 1.

[0034] The center lines of the suction cup frame 2, the suction cup body 1 and the suction cup cover 3 are collinear;

[0035] The end face of the suction cup cover 3 facing away from the suction cup body 1 is a plane and is perpendicular to the external threaded rod 2-1 of the suction cup frame 2.

[0036] A reinforcing plate 5 made of metal or other rigid material is provided on the outer side of the suction cup cover 3. The reinforcing plate 5 has a through hole 5-1 and a bent part 5-2 is formed at the bottom end of the reinforcing plate 5.

[0037] In this process, the external threaded rod 2-1 of the suction cup frame 2 passes through the through hole 5-1 of the reinforcing plate 5, and by tightening the hand-tightening nut 4 on the external threaded rod 2-1 of the suction cup frame 2, the suction cup body 1, the suction cup cover 3 and the reinforcing plate 5 are driven to be tightly attached to each other in the axial direction of the external threaded rod 2-1. When the vacuum suction cup is attached to the wall, the reinforcing plate 5 is always in contact with the plane of the suction cup cover 3, and the bent part 5-2 of the reinforcing plate 5 is always in contact with the wall.

[0038] The end face of the suction disc skeleton 2 in the suction disc body 1 in the embodiment is a concave curved surface, and has the same or close curved surface curvature as the curved surface of the suction disc body 1, so that the constraint on the deformation of the suction disc body 1 is relatively smaller, that is, the suction disc body 1 is more easily deformed in the process of pressing the vacuum suction disc to remove the air between the suction disc body 1 and the wall surface, and the pressing is more labor-saving.

[0039] In addition, as shown in Figure 4 and Figure 5 In the embodiment, a wall type shelf assembly is also provided, which comprises the vacuum suction disc.

[0040] As shown in Figure 6 As a second embodiment of the utility model, the vacuum suction disc in the embodiment comprises a suction disc body 1 made of rubber or other flexible material, and a suction disc skeleton 2 and a suction disc cover 3 made of metal or other rigid material.

[0041] One end of the suction disc skeleton 2 is embedded into the suction disc body 1, and the other end forms an externally threaded rod portion 2-1 extending outward and passes through the through hole one 3-1 of the suction disc cover 3, and the suction disc cover 3 covers the suction disc body 1.

[0042] The center lines of the suction disc skeleton 2, the suction disc body 1 and the suction disc cover 3 are collinear.

[0043] The end face of the suction disc cover 3 away from the suction disc body 1 is a plane, and is perpendicular to the externally threaded rod portion 2-1 of the suction disc skeleton 2.

[0045] The externally threaded rod portion 2-1 of the suction disc skeleton 2 passes through the through hole two 5-1 of the reinforcing plate 5, and when the vacuum suction disc is attached to the wall, the reinforcing plate 5 always abuts against the plane of the suction disc cover 3, and the bending portion 5-2 of the reinforcing plate 5 always abuts against the wall.

[0046] In addition, as shown in Figure 7 In the embodiment, a wall type shelf assembly is also provided, which comprises the vacuum suction disc.

[0047] In actual use, the wall-mounted shelf 6 is attached to the wall by a vacuum suction cup, and the bent part 5-2 of the reinforcing plate 5 is always in abutment with the wall. When a heavy object is placed in the wall-mounted shelf 6 attached to the wall, the wall-mounted shelf 6 tends to overturn away from the wall, and at the same time, the reinforcing plate 5 generates stress due to deformation. At this time, the wall provides vertical support force through the fixed point (vacuum suction cup attachment point), and also provides horizontal pulling force through the fixed point to resist part of the moment generated by gravity, while the remaining part of the horizontal moment is offset by the stress of the reinforcing plate 5, that is, the lateral pulling force of the fixed point is reduced, thereby avoiding damage to the vacuum state of the fixed point to the greatest extent, reducing the risk of the vacuum suction cup falling off, and improving the carrying capacity of the wall-mounted shelf 6.
