Description

Technical Field

[0001] The utility model relates to a storage rack, in particular to a storage rack fixed by a suction cup device, wherein a cover shell of the storage rack is connected and fixed to the suction cup device, and an adsorption piece on the suction cup device is used to fix the storage rack on a bearing surface such as a wall surface or a mirror surface. Background Art

[0002] Shelves are widely used in bathrooms, toilets, dressing rooms, kitchens, etc. They can be used to place toiletries, cosmetics, towels, and store condiments and cooking utensils. In the past, shelves were permanently fixed to the bearing surface by expansion screws during interior decoration. In order to meet the needs of interior decoration renewal, adding new shelves, changing the location of shelves, etc., punch-free and easy-to-install shelves are becoming more and more popular.

[0003] One way is to use a suction cup to adsorb the shelf on the wall, such as the utility model patent with authorization announcement number CN204293043U discloses a conveniently installed suction cup shelf with a hook, which includes a shelf, two suction cups, and a connecting rod. A mounting frame is integrally provided on the upper end of the suction cup shell, and a card slot is provided on the mounting frame. The shelf is connected to the mounting frame, and the installation method of adsorbing the suction cup on the wall does not damage the wall during installation. However, a shelf fixed only with an ordinary suction cup is easy to fall off due to the loosening of the shelf and the gravity of the items.

[0004] Therefore, as disclosed in the utility model patent with the authorization announcement number CN219733911U, a suction cup assembly and a shelf having the suction cup assembly are designed to include a seat body with a suction cup and a control member disposed on the seat body and capable of controlling the suction cup to adsorb or release, so as to facilitate the control of the suction and release of the suction cup, and the control member tightens the adsorption of the suction cup, and then the shelf is connected to the control members on two adjacent suction cup assemblies through a connecting rod, so that the shelf is fixed to the wall through the suction cup assembly. However, this design has a major defect, that is, the connection method between the shelf and the suction cup causes the gravity of the shelf and the items to generate axial pulling force on the suction cup, which easily drags the suction cup off the wall, and also affects the adsorption firmness of the suction cup.

[0005] Another solution is to use a suction cup and a strong glue together to enhance the adsorption effect. For example, the utility model patent with the authorization announcement number CN207679357U discloses a shelf with a suction cup, which includes a suction cup, a shell and a slider. The suction cup is arranged on the back of the shell, and the slider can be movably arranged in the shell, and the slider is provided with a strong glue sticker for sticking to the wall. However, this combined adsorption method is difficult to disassemble, and the strong glue can easily damage the wall, and glue marks will be left after disassembly. Utility Model Content

On this basis, by forming an avoidance connection between the second cover shell of the storage rack and the first cover shell of the suction cup device, and installing the rack body on the second peripheral side wall, the overall gravity of the storage rack and the objects thereon mainly acts on the second peripheral side wall of the second cover shell and the first peripheral side wall of the first cover shell, thereby producing at least four beneficial effects compared with the prior art:

[0077] First, the storage rack is not directly fixedly connected to the suction cup member or the control member, but is fixedly connected to the suction cup device by using the second cover shell mounted on the first cover shell, thereby avoiding the key structure on which the suction cup device firmly adsorbs the bearing surface, thereby enhancing the adsorption firmness of the suction cup device, and further enhancing the firmness of the storage rack fixed to the bearing surface;

[0078] Second, the force of the rack on the suction cup device is mainly in the radial direction, and the force in the axial direction is very small. The axial force will pull the suction cup away from the bearing surface, causing the suction cup to loosen or even fall off. Therefore, this design can reduce the negative impact of the rack on the suction force of the suction cup;

[0079] Third, the design that the inner contour of the second peripheral side wall matches the outer contour of the first peripheral side wall can ensure the maximum contact area between the two, and the radial force of the rack on the suction cup device is dispersed between the two peripheral side walls, avoiding excessive pressure at a single point, which may cause the vacuum structure adsorbed between the suction cup and the bearing surface to be broken from that point;

[0080] Fourth, most of the structure of the adsorption device is covered in the first cover shell and the second cover shell, and a window is opened on the second cover shell for exposing the control part. The appearance is simple and beautiful, which is convenient for users to operate the control part and prevents the suction cup and other connecting parts from aging due to dust accumulation, water vapor contamination, etc., which affects the adsorption firmness.

[0081] Furthermore, a fastening structure is provided between the first cover shell and the second cover shell to enhance the stability and firmness of the fixed connection between the storage rack and the suction cup device, thereby preventing the storage rack from loosening and falling.

The rack 50 is installed on the second peripheral side wall 42, and specifically in this embodiment, the two ends of one rack 50 are respectively installed above the second peripheral side wall 42 of the second housing 40 on both sides, and the two ends of the other rack 50 are respectively installed below the second peripheral side wall 42 of the second housing 40 on both sides.

[0109] The second cover shell 40 is disposed outside the first cover shell 20, the first cover shell 20 is located in the second concave cavity 43, and the inner contour of the second peripheral side wall 42 matches the outer contour of the first peripheral side wall 22, so as to form an avoidance connection between the second cover shell 40 of the rack 110 and the first cover shell 20 of the suction cup device 120. Furthermore, a fastening structure is provided between the first cover shell 20 and the second cover shell 40 to fix the first cover shell 20 and the second cover shell 40, thereby fixing the rack 110 and the suction cup device 120.

[0110] It can be seen that the rack 100 fixed by the suction cup device provided by the utility model, firstly, the rack is fixed on the bearing surface m by the suction cup device, and can be repeatedly disassembled. On this basis, by forming an avoidance connection between the second cover shell 40 of the rack 110 and the first cover shell 20 of the suction cup device 120, and installing the frame body 50 on the second peripheral side wall 42, the overall gravity of the rack 110 and the objects thereon mainly acts on the second peripheral side wall 42 of the second cover shell 40 and the first peripheral side wall 22 of the first cover shell 20, thereby producing at least four beneficial effects compared with the prior art:

[0111] First, the storage rack 110 is not directly fixedly connected to the suction cup member 10 or the operating member 30, but is fixedly connected to the suction cup device 120 by means of the second cover 40 sleeved on the first cover 10, thereby avoiding the key structure on which the suction cup device 120 firmly adsorbs the bearing surface m, thereby enhancing the adsorption firmness of the suction cup device 120, and further enhancing the firmness of the storage rack 110 fixed to the bearing surface m;

[0112] Second, the force of the rack 110 on the suction cup device 120 is mainly in the radial direction, and the force in the axial direction is very small. The force in the axial direction will pull the suction cup member 10 away from the bearing surface m, causing the suction cup member 10 to loosen or even fall off. Therefore, this design can reduce the negative impact of the rack 110 on the suction force of the suction cup member 10;

[0113] Third, the design that the inner contour of the second peripheral side wall 42 matches the outer contour of the first peripheral side wall 22 can ensure the maximum contact area between the two, and the radial force of the rack 110 on the suction cup device 120 is dispersed between the two peripheral side walls, so as to avoid excessive pressure at a single point, which may cause the vacuum structure between the suction cup member 10 and the bearing surface m to be broken from that point;

[0114] Fourth, most of the structure of the adsorption device 120 is covered in the first cover shell 20 and the second cover shell 40, and a window 44 is opened on the second cover shell 40 for exposing the operating member 30. The appearance is simple and beautiful, which is convenient for users to operate the operating member 30 and prevents the suction cup member 10 and other connecting parts from aging due to dust accumulation, water vapor contamination, etc., which affects the adsorption firmness.

[0115] Furthermore, a fastening structure is provided between the first cover shell 20 and the second cover shell 40 to enhance the stability and firmness of the fixed connection between the storage rack 110 and the suction cup device 120 to prevent the storage rack from loosening and falling.

[0116] It should be noted that, in the present embodiment, a second cover shell 40 is provided on each side of the storage rack 110, and each second cover shell 40 is provided on the outside of the first cover shell 20 of a group of suction cup devices 120, and the two sides of the storage rack 110 are respectively fixedly connected to a group of suction cup devices 120. In other embodiments, there may be only a single-layer frame 50, or multiple layers of frame 50 may be installed and fixed on the second peripheral side wall 42 of each second cover shell 40, and the installation and fixing position is not limited to the top or bottom of the second peripheral side wall 42, and may also be located on the side. It is also possible to set more than two groups of suction cup devices 120 and corresponding second cover shells 40 according to the length requirements of the frame 50. The present embodiment only takes the implementation method of two groups of suction cup devices 120 corresponding to two second cover shells 40 and a double-layer frame 50 as an example, so that those skilled in the art can more easily understand the above expansion method.

[0117] In addition, when the items carried are not heavy, only one set of suction cup devices 120 may be used to fix one rack 110. The rack 110 is not limited to a rod rack or a frame structure, but may be expanded to different shapes, such as a hook, a hair dryer rack, a mirror rack, a wall-mounted storage box, etc., and may be any one of the aforementioned shapes or a combination of two or more thereof, such as a combination of a hook and a hair dryer rack, wherein the hook is installed below the second peripheral side wall 42 and the hair dryer rack is installed on the side of the second peripheral side wall 42.

[0118] like Figure 4 and Figure 5 As shown, in this embodiment, the fastening structure is arranged between the first panel 21 and the second panel 41. Specifically, the fastening structure includes two first connecting posts z1 arranged on the first panel 21 and two second connecting posts z2 arranged on the second panel 42. The first connecting post z1 is provided with a first connecting hole k1 penetrating the first panel 21, and the second connecting post z2 is provided with a second connecting hole k2 that does not penetrate the second panel 41. The inner diameter of the first connecting hole k1 matches the outer diameter of the second connecting post z2.

[0119] In this embodiment, two first connection posts z1 are convexly arranged on the inner side of the first panel 21, that is, located in the first concave cavity 23, and the back end of the first connection hole k1 is exposed from the back side of the first panel 21. The two first connection posts z1 are arranged up and down and give way to the suction cup member 10 without causing any obstruction to the suction cup member 10. Correspondingly, two second connection posts z2 are convexly arranged on the inner side of the second panel 41, that is, located in the second concave cavity 43, and the two second connection posts z2 are arranged above and below the window 44.

[0120] During installation, the second connecting column z2 is inserted into the first connecting hole k1 from the back side of the first panel 21, and two screws d are respectively inserted into the second connecting hole k2 of the second connecting column z2 from the inner side of the first panel 21 to fasten the first connecting column z1 and the second connecting column z2, thereby fastening the first cover shell 20 and the second cover shell 40 to prevent the second cover shell 40 from loosening from the first cover shell 20 and causing the storage rack 110 to fall off.

[0121] In other embodiments, the fastening structure may be provided in other ways, for example, a snap-fit ​​structure may be provided between the first housing 20 and the second housing 40, or screws may be directly used to fasten the first panel 21 and the second panel 41, or the fastening structure may be provided between the first peripheral side wall 22 and the second peripheral side wall 23. The fastening structure is not limited to being provided on the inner side of the housing, for example, the screw d may also be inserted from the outer side of the second housing 40. However, the fastening structure provided in this embodiment can at least achieve the following beneficial effects:

[0122] First, the fastening structure is arranged between the first panel 21 and the second panel 41 instead of between the first peripheral side wall 22 and the second peripheral side wall 23. Firstly, the peripheral side wall is usually narrow, and the arrangement space of the fastening structure is relatively cramped. Secondly, it is easy to cause damage and cracking of the peripheral side wall. Thirdly, it has a negative impact on the effect of the avoidance connection between the two peripheral side walls.

[0123] Second, the two connecting columns are inserted into each other before being tightened, which not only realizes the all-round tightening effect in the axial, radial and circumferential directions, making it more firm and reliable, but also avoids the screws hitting the cover directly, causing the cover to crack;

[0124] Third, the two groups of connecting columns are arranged on the inner side of the two panels, the second connecting column z2 passes through the first connecting column z1, and the screws pass through the second connecting holes k2 of the second connecting column z2 from the inner side of the first panel 21, and the second connecting holes k2 do not penetrate the second panel 42, thereby avoiding the fastening structure from being exposed from the outer surface of the second cover shell 40. Not only does it achieve a neat and beautiful appearance, the hidden screws d are not easy to scratch the user or objects, and it can also reduce the fastening structure from dust accumulation, water vapor contamination and aging.

[0125] In addition, in other embodiments, the number of first connecting columns z1 and second connecting columns z2 can also be adjusted according to the actual component size and application scenarios. For example, when the storage rack 110 is designed to be larger and used for the application scenario of placing heavy objects, the number of first connecting columns z1 and second connecting columns z2 can be appropriately increased.

[0126] like Figure 6 , Figure 8 and Fig. 9 As shown, corresponding to the design of the double-layer frame 50 of this embodiment, a frame fixing base 51 is respectively provided on the upper and lower sides of the second peripheral side wall 42 of each second cover shell 40, and the frame fixing base 51 includes a base plate 52 and a support seat 53 fixed on the back side of the base plate 52. The base plate 52 extends from the front end of the second peripheral side wall 42 to the outer periphery. In this embodiment, the upper and lower base plates 52 extend upward and downward respectively. A support groove 54 is provided on the support seat 53 for the end of the frame 50 to be inserted.

[0127] During installation, when the second cover shell 40 is fixed on the bearing surface m by suction with the help of the suction cup device 120, since the base plate 52 extends from the front end of the second peripheral side wall 42 to the outer periphery, the front side of the base plate 52 is in close contact with the bearing surface m, and the supporting seat 53 extends outward from the back side of the base plate 52. The two side ends of the upper frame 50 are respectively inserted into the supporting grooves 54 of the two upper supporting seats 53, and the two side ends of the lower frame 50 are respectively inserted into the supporting grooves 54 of the two lower supporting seats 53, so as to fix the two layers of the frame 50 between the frame fixing bases 51 on both sides.

[0128] In other embodiments, the number of the frame fixing bases 51 can be increased or decreased according to the number of layers of the frame 50. Of course, the frame 50 can also be installed on the second peripheral side wall 42 of the second cover 40 in other ways, such as by welding, screw fastening, etc. However, the structure of the frame fixing base 51 provided in this embodiment can be adapted to frames 50 of different lengths. For example, when the frame 50 is shorter or longer, the distance between the second cover 40 on both sides can be adjusted.

[0129] Preferably, the second cover shell 40 and the frame fixing base 51 are made of metal material, the frame 50 itself can also be made of metal material, and the base plate 52 and the second cover shell 40 are integrally formed, thereby improving the overall mechanical strength.

[0130] like Figure 2 and Figure 7 As shown, a return spring s is provided between the back side of the suction cup member 10 and the first concave cavity 23, and the return spring s can drive the suction cup member 10 to return to its original position to release the bearing surface m. The return spring s is sleeved on the connecting rod 11, with the front end abutting against the back side of the suction cup member 10 and the rear end abutting against the bottom of the first concave cavity 23, that is, the inner side of the first panel 21.

[0131] Of course, the suction cup member 10 can also be directly controlled by the operating member 30 to perform floating deformation, but the setting of the reset spring s has at least two functions: first, when the suction cup member 10 adsorbs the bearing surface m, the reset spring s gives the suction cup member 10 a force that presses against the bearing surface m, so that the adsorption effect is enhanced; second, when the operating member 30 controls the suction cup member 10 to release, the reset spring s is released synchronously and pushes the suction cup member 10 to reset, making the operation more labor-saving and easy.

[0132] like Figure 2 , Figure 3 , Figure 7 As shown, the control member 30 provided in this embodiment is a knob assembly, including a knob 31, a latch 32 and a concave-convex ring 33. The concave-convex ring 33 is circumferentially fixed to the knob 31, that is, the concave-convex ring 33 and the knob 31 do not rotate relative to each other in the circumferential direction, so that the knob 31 can drive the concave-convex ring 33 to rotate circumferentially.

[0133] The back of the concave-convex ring 33 is an annular concave-convex end surface 34. The latch 32 is connected to the connecting rod 11, and the connecting rod 11 passes through the concave-convex ring 33 so that the latch 32 is tightly against the annular concave-convex end surface 34. In this embodiment, the latch 32 passes through the end of the connecting rod 11 to connect the connecting rod 11, and both ends of the latch 32 are tightly against the annular concave-convex end surface 34. The annular concave-convex end surface 34 is designed as a continuous concave-convex structure, and has a first position p1 and a second position p2. The first position p1 is relatively convex, and the second position p2 is relatively concave, so the first position p1 is higher than the second position p2.

[0134] The knob 31 drives the concave-convex ring 33 to rotate forward, so that the latch 32 is pressed against the first position p1 of the annular concave-convex end surface 34, and the suction cup member 10 is deformed with a tendency to approach the first panel 21, and the reset spring s is squeezed between the suction cup member 10 and the first panel 21, thereby manipulating the suction cup member 10 to deform to adsorb the bearing surface m. The knob 31 drives the concave-convex ring 33 to rotate reversely, so that the latch 32 is pressed against the second position p2 of the annular concave-convex end surface 34, and the reset spring s is released to push the suction cup member 10 to reset with a tendency to deform away from the first panel 21, thereby manipulating the suction cup member 20 to deform to release the bearing surface m.

[0135] The second panel 41 is provided with a window 44 that matches the shape of the knob 31 to expose the knob 31. Since the knob 31 is disc-shaped in this embodiment, the window 44 is circular.

[0136] Embodiment 2:

[0137] like Figures 10 to 12 The present embodiment shows a rack 100' fixed by a suction cup device, including a rack 110' and two sets of suction cup devices 120'. Both sides of the rack 110' are fixedly connected to one set of suction cup devices 120', respectively, so that the rack 110' is adsorbed and fixed on a bearing surface such as a wall or a mirror by the suction cup devices 120'.

[0138] like Fig.11 and Fig.12 As shown, the control member 30' provided in this embodiment is a handle 31', one end of which is hinged to the connecting rod 11' through a latch 32', and the other end is a free end. In this embodiment, the lower end of the handle 31' is hinged to the connecting rod 11' through the latch 32', and the upper end of the handle 31' is a free end. In other embodiments, the free end of the handle 31' may also face downward or to the side, but the orientation setting of this embodiment is more in line with the operating habits of general users.

[0139] The latch 32' passes through the end of the connecting rod 11' to connect the connecting rod 11', and passes through the lower end of the breaking handle 31' to hinge the lower end of the breaking handle 31' to the end of the connecting rod 11'.

[0140] like Fig.12 As shown, a protruding structure 33' is eccentrically provided on the inner side of the lower end of the handle 31'. When the handle 31' is buckled relative to the first panel 21', the protruding structure 33' presses against the back side of the first panel 21', and the suction cup 10' deforms with a tendency to approach the first panel 21'. The reset spring s' is squeezed between the suction cup 10' and the first panel 21', thereby manipulating the suction cup 10' to deform to adsorb the bearing surface. When the handle 31' is opened relative to the first panel 21', the reset spring s' releases and pushes the suction cup 10' to reset with a tendency to deform away from the first panel 21', thereby manipulating the suction cup 10' to deform to release the bearing surface.

[0141] like Figures 10 to 12 As shown, a window 44' matching the shape of the breaking handle 31' is provided on the second cover 40'. In this embodiment, the breaking handle 31' is roughly rectangular, and the outline of the window 44' is also roughly rectangular, and extends from the second panel 41' to the second peripheral side wall 42' to expose the free end of the breaking handle 31', so as to facilitate user operation. Of course, in other embodiments, the breaking handle 31' can also be other shapes, such as semicircular, and the window 44' can also be provided on the second panel 41' instead of extending to the second peripheral side wall 42', and a groove or notch can be provided at the free end of the breaking handle 31' to facilitate user operation.

[0142] like Fig.11 As shown, in this embodiment, the fastening structure includes four first connecting posts z1' arranged on the first panel 21' and four second connecting posts z2' arranged on the second panel 42'. The first connecting posts z1' are provided with first connecting holes k1' penetrating the first panel 21', and the second connecting posts z2' are provided with second connecting holes (not shown in the figure) that do not penetrate the second panel 41', and the inner diameter of the first connecting hole k1' matches the outer diameter of the second connecting posts z2'.

[0143] In this embodiment, four first connection columns z1' are protruding from the back side of the first panel 21' and are arranged at four corners, and correspondingly, four second connection columns z2' are protruding from the inner side of the second panel 41'. During installation, the second connection column z2' is inserted into the first connection hole k1', and four screws d' are respectively inserted from the inner side of the first panel 21' into the second connection holes of the second connection column z2' to fasten the first connection column z1' and the second connection column z2', thereby fastening the first cover 20' and the second cover 40' to prevent the second cover 40' from being loosened from the first cover 20', causing the storage rack 110' to fall off.

[0144] The structures and connection methods of other components of this embodiment are similar to those of the first embodiment. The expansion of corresponding technical features has also been elaborated in detail in the first embodiment and will not be repeated here.

[0145] Embodiment three:

[0146] like Figures 13 to 15 The present embodiment shows a storage rack 100" fixed by a suction cup device, including a storage rack 110" and two groups of suction cup devices 120", wherein both sides of the storage rack 110" are fixedly connected to one group of suction cup devices 120", so that the storage rack 110" is adsorbed and fixed on a bearing surface such as a wall or a mirror by the suction cup devices 120".

[0147] like Figures 13 to 15As shown, what is different from the first embodiment is that a frame fixing base 51" is respectively provided on the upper and lower parts of the second peripheral side wall 42" of each second cover shell 40". The frame fixing base 51" includes a base 52" and a supporting base 53" fixed on the back side of the base 52". The base 52" includes a third panel 41y" and a third peripheral side wall 42y". The third peripheral side wall 42y" is formed by an integral extension of the second peripheral side wall 42", and the third panel 41y" is formed by an integral extension of the second panel 41". The upper and lower bases 52" also extend upward and downward respectively.

[0148] The supporting seat 53" is fixed on the third panel 41y", and a supporting groove 54" is provided on the supporting seat 53" for the end of the frame 50" to be inserted. The connection method between the frame 50" and the supporting groove 54" of the supporting seat 53" is the same as that in the first embodiment, and is not repeated here. Similarly, in other embodiments, the number of frame fixing bases 51" can be increased or decreased according to the number of layers of the frame 50".

[0149] like Fig.14 and Fig.15 As shown, in the present embodiment, the fastening structure is arranged between the first panel 21" and the third panel 41y". Specifically, the first cover shell 20" and the second cover shell 40" are both roughly circular, so as to form an integrated visual effect with the circular shape of the knob in appearance. Compared with the roughly rectangular second cover shell in the first embodiment, the area of ​​the second panel 41" around the window 44" is smaller, so the two second connecting columns z2" are protruding on the inner side of the second panel 41" that is a part of the third panel 41y" that extends integrally to form the base 52".

[0150] Correspondingly, two lugs 20e" extend integrally from the upper and lower parts of the first cover shell 20", and two first connecting columns z1" are protruded from the inner side of the first panel 21" of the lugs 20e". Therefore, during installation, the second cover shell 40" is covered on the outside of the first cover shell 20", the two lugs 20e" of the first cover shell 20" enter the interior of the base 52", the second connecting column z2" penetrates into the first connecting hole k1" from the back side of the first panel 21", and the two screws d" penetrate into the second connecting hole k2" of the second connecting column z2" from the inner side of the first panel 21", respectively, to fasten the first cover shell 20" and the second cover shell 40".

[0151] like Figures 13 to 15As shown, in this embodiment, the storage rack 110" also includes an extended frame body 50t", and the extended frame body 50t" is a hook frame, a hook fixing strip g1 and a series of hooks g2 distributed on the hook fixing strip g1. The two ends of the hook fixing strip g1 are fastened to the bearing surface m" with screws, and are snapped into the slot g3 on the front side of the third peripheral side wall 42y" to be connected to the third peripheral side wall 42y" of the base 51", so as to be fixed between the base 52" located below the second cover shell 40" and the bearing surface m". Of course, in other embodiments, the extended frame body 50t" and the base 51" can also be connected in other ways, such as welding or fixing with screws to the base 51".

[0152] In this embodiment, the expansion frame 50t" is connected to the base 52" by integrally extending the second cover shell 40". In fact, the expansion frame 50t" is also installed on the second peripheral side wall 42". Therefore, the specific implementation method provided in this embodiment, on the basis of producing the beneficial effects mentioned in the first embodiment, further creates expansion space for enriching the shape of the storage rack and realizing various functions.

[0153] Similarly, the storage rack 110" is not limited to rod racks and frame structures, but can also be expanded into different shapes, such as hooks, hair dryer racks, mirror racks, wall-mounted storage boxes, etc., and can be any one of the aforementioned shapes or a combination of two or more. Not only can the rack 50" itself be expanded, but the expanded rack 50t" can also be expanded and transformed, for example, expanded into a double-row hook rack, or a combination of a hook rack and a wall-mounted storage box.

[0154] The structures and connection methods of other components of this embodiment are similar to those of the first embodiment. The expansion of corresponding technical features has also been elaborated in detail in the first embodiment and will not be repeated here.

[0155] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0156] The above is an introduction to the storage rack fixed by the suction cup device provided by the utility model. The principle and implementation method of the utility model are described in this article using specific examples. The description of the above embodiments is only used to help understand the utility model and its core idea. It should be pointed out that for ordinary technicians in this technical field, the utility model can also be improved and modified without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
