Description

Technical Field

[0001] The utility model belongs to the technical field of hooks in daily necessities, and in particular relates to a switching device for a suction cup. Background Art

[0002] In existing products, the suction cup is directly connected to external components such as a hanging basket, and its usage scenario is relatively single. It is not adaptable to different external components, which requires the suction cup and the hanging basket to be used in pairs, increasing the cost of use. For example, Chinese patent CN216984455 U discloses "A suction device and a hanging basket", which connects the suction component and the hanging basket part through a connecting seat. The disassembly and assembly between the suction component and the hanging basket part is relatively complicated, and the scope of use is small. For example, Chinese patent CN 215805692 U discloses "Suction cup connector, hanging device and suction cup device", in which the connecting body is assembled and connected with the hanging part and the suction cup part. When the hanging part needs to be replaced, it needs to be disassembled and reinstalled, and the operation is relatively cumbersome. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a transfer device for a suction cup, which realizes the connection between the suction cup and an external component, can adapt to different external components, broadens the scope of application, and has a reasonable layout and is easy to use.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a switching device for a suction cup, comprising:

[0005] The first adapter comprises a body connectable to the suction cup, and an extension arm connected to the body, wherein the extension arm is provided with a locking unit;

[0006] The second adapter comprises a base, a lower buckle portion that can be connected to the external component, and an upper buckle portion that can be connected to the locking unit in cooperation;

[0007] The upper buckling part and the lower buckling part are respectively located on two opposite side surfaces of the base.

[0008] The utility model utilizes the cooperation of the first adapter and the second adapter to achieve the connection between the suction cup and the external component, which can adapt to different external components and suction cups. There is no need to use the suction cup and the external component in pairs, which reduces the use cost and increases the flexibility of the cooperation between the suction cup and the external component. The conversion structure between the second adapter and the first adapter and the external component is simple and convenient. There is no need to disassemble the suction cup for assembly, which reduces the difficulty of assembly and provides a good user experience. The upper buckle part connected with the first adapter and the lower buckle part connected with the external component are respectively located on two opposite sides of the base, and the layout is reasonable, so that when the second adapter is connected to the suction cup and the external component, the operation is convenient and no interference will occur.

[0009] Furthermore, the extension arm forms an upper protrusion that is flush or nearly flush with the suction surface of the suction cup. The upper protrusion increases the contact area between the extension arm and the vertical plane, strengthens the support effect, avoids shaking, and is also beneficial to the suction of the suction cup, making the suction cup have a higher suction strength.

[0010] Furthermore, the base forms a lower protrusion that is flush or nearly flush with the suction surface of the suction cup. The lower protrusion increases the contact area between the base and the vertical plane, strengthens the supporting effect, and the suction surface, the upper protrusion, and the lower protrusion cooperate to greatly increase the stability of the overall structure, and the suction effect of the suction cup is better.

[0011] Furthermore, the upper protrusion is located at the bottom end of the extension arm, and extends along the length direction and width direction of the extension arm. Such an arrangement can further increase the contact area and support area between the extension arm and the vertical plane, and the support effect is better.

[0012] Furthermore, the lower protrusion is located at the bottom of the base, and extends along the length and width of the base; the portion of the lower protrusion extending along the length of the base is in a flared cone shape. This arrangement can further increase the contact area and support area between the base and the vertical plane, and the support effect is better.

[0013] Furthermore, the main body is an annular body arranged on the suction cup. The main body has a simple structure and can be used in combination with suction cups with different adsorption forces to increase the flexibility of use.

[0014] Furthermore, the base forms a limiting ridge that can abut against the extension arm; the base includes an upper body and a lower body, and the lower body is wider than the upper body. During assembly, the extension arm slides against the limiting ridge, which facilitates assembly positioning and also prevents the extension arm and the base from shaking after assembly.

[0015] Furthermore, the upper buckle part is hung on the first adapter from top to bottom, and the external component is hung on the lower buckle part from top to bottom. This arrangement facilitates the external component, the second adapter, and the first adapter to be installed in sequence from bottom to top to achieve assembly, or the first adapter, the second adapter, and the external component to be installed in sequence from top to bottom to achieve assembly, with a reasonable layout, no interference, and in line with the user's assembly order.

[0016] Furthermore, the upper buckle part includes an upper buckle body, upper wings extending from the upper buckle body to both sides, and a locking groove; the snap unit includes a slot for the upper buckle body to be inserted from top to bottom, an upper baffle for blocking the upper wing, and a locking protrusion that can fall into the locking groove; the lower buckle part includes a lower buckle body, and lower wings extending from the lower buckle body to both sides, and the external component forms a hanging groove for the lower wing to extend from bottom to top and limit the fit. The structures of the upper buckle part and the lower buckle part are simple and reasonable, and the matching connection with the snap unit and the external component is convenient and stable.

[0017] Furthermore, the lower buckle body is a base, and the lower wings are located on both sides of the base; or, the lower buckle body is located on the surface of the base. The structure of the lower buckle part is diverse, and it can adapt to bases of different areas, and has high adaptability.

[0018] The beneficial effects of the utility model are: 1) the connection between the suction cup and the external component is realized by utilizing the cooperation of the first adapter and the second adapter, which can adapt to different external components and suction cups, thereby reducing the use cost and increasing the use flexibility; 2) the transfer structure between the second adapter and the first adapter and the external component is simple and convenient, thereby reducing the difficulty of assembly; 3) the upper buckle part and the lower buckle part are respectively located on the opposite sides of the base, and the layout is reasonable; 4) the upper protrusion part and the lower protrusion part respectively increase the contact area between the extension arm, the base and the vertical plane, thereby enhancing the supporting effect, avoiding shaking, and also facilitating the adsorption of the suction cup; 5) the structure of the lower buckle part is diverse and highly adaptable.

DETAILED DESCRIPTION

[0043] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0044] Embodiment 1

[0045] like Figure 1-Figure 6 As shown, a switching device for a suction cup includes a first switching component 1 and a second switching component 2.

[0046] The first adapter 1 includes a body 11 that can be connected to the suction cup 3, and an extension arm 12 connected to the body 11, and the extension arm 12 is provided with a snap-fit ​​unit 13. In this embodiment, the body 11 is an annular body provided on the suction cup 3, and the extension arm 12 is formed by extending outward from the annular body. Of course, the body 11 can also be another structure, and the suction cup 3 can adopt an existing design, which is not specifically limited.

[0047] The second adapter 2 includes a base 21, a lower buckle portion 22 that can be connected to the external component 4, and an upper buckle portion 23 that can be connected to the snap unit 13, and the upper buckle portion 23 and the lower buckle portion 22 are respectively located on two opposite sides of the base 21. In this embodiment, the upper buckle portion 23 and the lower buckle portion 22 are respectively located on the back and front of the base 12. The external component 4 can be any storage component. In this embodiment, a storage basket is used as an example for description, but it is not limited to this.

[0048] Specifically, the side of the second adapter 2 facing the external component 4 is defined as the front side, on which the lower buckle portion 22 is disposed, and the side of the second adapter 2 facing away from the external component 4 is defined as the back side, on which the upper buckle portion 23 is disposed.

[0049] like Figure 3 As shown, the base 21 includes an upper body 213 and a lower body 214. In this embodiment, the widths of the upper body 213 and the lower body 214 are equal, and the widths thereof are greater than the width of the extension arm 12. The upper body 213 of the base 21 forms a limiting ridge 212 that can abut against both sides of the extension arm 12, so that the extension arm 12 slides against the limiting ridge 212 during assembly, which facilitates assembly positioning and also prevents the two from shaking after assembly.

[0050] In this embodiment, the upper buckling portion 23 includes an upper buckling body 231 , upper wings 232 extending from the upper buckling body 231 to both sides, and a locking groove 233 . The upper buckling body 231 is fixedly connected to the back side of the upper portion of the base 21 .

[0051] like Fig.10 As shown, the snap-fit ​​unit 13 includes a slot 131 for the upper snap-fit ​​body 231 to be inserted from top to bottom, an upper baffle 132 for preventing the upper wing 232 from being disengaged, and a locking protrusion 133 that can fall into the locking groove 233. In this embodiment, the front and back sides of the slot 131 are both through, the locking protrusion 133 is located above the slot 131, and the two upper baffles 132 are located on both sides of the front side of the slot 131, and the gap between the two is substantially equal to the width of the upper snap-fit ​​body 231. When the upper snap-fit ​​part 23 is connected with the snap-fit ​​unit 13, it slides into the top opening of the slot 131, and the upper snap-fit ​​body 231 passes through between the upper baffles 132 on both sides, and the front side of the extension arm 12 abuts against the back side of the base 21, and the overall assembly structure is stable.

[0052] In this embodiment, if Figure 4 As shown, the structure of the lower buckle part 22 is basically the same as that of the upper buckle part 23, and includes a lower buckle body 221 and lower wings 222 extending from the lower buckle body 221 to both sides, and the lower buckle body 221 is located on the front side of the base 21. Fig. 9 As shown, the external assembly 4 forms a hanging groove 41 for the lower wing 222 to extend from bottom to top and limit fit. The hanging groove 41 is formed by two 7-shaped card slots extending along the height direction of the hanging basket and a convex edge at the top of the hanging basket. The limit fit here means that the lower wings 222 on both sides are just inserted into the 7-shaped card slots, and the lower buckle part 22 can slide along the hanging groove 41 until the top surface of the lower buckle part 221 abuts against the convex edge at the top of the hanging basket, so that the lower buckle part 221 will not shake left and right in the hanging groove 41, and will not be separated from the hanging groove 41 upward.

[0053] Of course, in other embodiments, the upper buckle portion 23, the snap-fit ​​unit 13, the lower buckle portion 22, and the hanging groove 41 may also be other structures, without specific limitation. As long as the upper buckle portion 23 can be hung on the first adapter 1 from top to bottom, and the external component 4 can be hung on the lower buckle portion 22 from top to bottom. Of course, it can also be said here that the snap-fit ​​unit 13 of the first adapter 1 is mounted on the upper buckle portion 23 from bottom to top, and the lower buckle portion 22 is mounted on the external component 4 from bottom to top, without specific limitation.

[0054] In order to make the adapter device cooperate with the suction cup 3 and the vertical plane such as the wall and the perforated board more stable, an upper protrusion 121 flush with or nearly flush with the adsorption surface 31 of the suction cup 3 is formed on the extension arm 12. The upper protrusion 121 increases the thickness of the extension arm 12. It is arranged at the bottom end of the extension arm 12. It cooperates with the adsorption surface 31 to increase the contact area with the vertical plane, avoids shaking, and the overall structure is stable, which is also beneficial to the adsorption of the suction cup 3.

[0055] Similarly, a lower protrusion 211 flush with or nearly flush with the adsorption surface 31 of the suction cup 3 can also be formed on the base 21. The lower protrusion 211 increases the thickness of the second adapter 2. It is arranged at the bottom end of the base 21. Therefore, the adsorption surface 31, the upper protrusion 121, and the lower protrusion 211 cooperate to greatly increase the stability of the overall structure.

[0056] The upper protrusion 121 and the lower protrusion 211 can be of any structure. In this embodiment, the upper protrusion 121 extends along the length and width of the extension arm 12, that is, the upper protrusion 121 is raised on three sides, which increases the contact area and strengthens the support effect. In order to prevent the upper protrusion 121 from having an adverse effect on the adsorption of the suction cup 3, its extension surface in the length direction of the extension arm 12 can be an inclined surface. Similarly, the lower protrusion 211 extends along the length and width of the base 21, and its structure is similar to that of the upper protrusion 121, which will not be repeated.

[0057] Different numbers of suction cups 3 and adapters can be selected according to the specific structure of the external component 4. In this embodiment, the external component 4 is a hanging basket with a larger width, and two suction cups 3 and adapters are selected.

[0058] When in use, the first adapter 1 and the second adapter 2 can be assembled first, and then the suction cup 3 can be vacuum adsorbed on a vertical plane, or the suction cup 3 and the first adapter 1 can be vacuum adsorbed on a vertical plane first, and then the second adapter 2 and the first adapter 1 can be assembled; similarly, the assembly order of the second adapter 2 and the external component 4 is not limited.

[0059] Embodiment 2

[0060] like Figure 11-Figure 16 As shown, in this embodiment, the width of the lower body 214 of the base 21 is greater than the width of the upper body 213. In order to increase the contact area with the vertical plane, the portion of the lower protrusion 211 extending along the length direction of the base 21 is in a flared cone shape, that is, the portion of the lower protrusion 211 extending along the width direction of the base 21 is lengthened.

[0061] When the area of ​​the lower body 214 is enlarged, the volume of the lower buckle body 221 and the lower wing 222 is also increased. In addition, the hanging groove 41 can be formed by two 7-shaped grooves extending along the height direction of the hanging basket and a convex edge extending along the width direction of the hanging basket, and the convex edge is against the lower buckle part 22.

[0062] The other structures are the same as those in the first embodiment and will not be described in detail.

[0063] Embodiment 3

[0064] like Figure 17-Figure 21As shown, in this embodiment, the base 21 and the lower buckle part 22 are an integrated structure, that is, the lower buckle body 221 is the base 21, and the lower wings 222 are located on both sides of the base 21. It should be noted here that the upper buckle part 23 and the lower buckle part 22 are respectively located on the opposite sides of the base 21, which are not necessarily completely opposite to the front and back, but can be relative concepts, or in other words, in this embodiment, the base 21 is divided into two parts, the front and back, the upper buckle part 23 is located on the back of the rear part of the base 21, and although the lower buckle part 22 is a part of the base 21, it can also be the front of the front part of the base 21.

[0065] The other structures are the same as those in the second embodiment and will not be described in detail.

[0066] Embodiment 4

[0067] like Fig. 22 , Fig.23 As shown, in this embodiment, although the width of the lower body 214 of the base 21 is increased, the width of the lower protrusion 211 is equivalent to the width of the upper body 213.

[0068] The other structures are the same as those in the first embodiment and will not be described in detail.

[0069] The above specific implementation modes are used to explain the present invention rather than to limit the present invention.
