Description

Technical Field

[0001] This utility model relates to the field of shelving accessories, specifically to a flip-type shelving base. Background Technology

[0002] Existing shelves are fixed using methods such as adhesive tape and suction cups. Conventional suction cups require a smooth surface for adhesion and are prone to falling off due to air leakage. To address this issue, many suction cups now have an added adhesive layer on the back. This improves airtightness and uses the adhesive force to assist in fixing, greatly enhancing the fixation strength. In some cases, the adhesion becomes so strong that it becomes an irremovable fixation. However, because the suction cup housing of existing shelves abuts against the suction cup after it is fixed, the suction cup with the adhesive layer cannot be removed, making it difficult to adjust or move the shelf. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a flip-type shelf base with high overall aesthetics, strong adsorption force, and easy disassembly and replacement of the suction cup assembly or suction cup.

[0004] To address the above problems, the following technical solution is provided: a flip-type shelf base, including a fixed base, on which a shelf and a mounting position are provided, and a suction cup assembly is provided at the mounting position; the suction cup assembly includes a housing, a suction cup on the back of the housing, a pull rod passing through the housing, and an eccentric handle hinged to the pull rod on the front of the housing. The hinge axis of the eccentric handle and the pull rod is perpendicular to the axis of the pull rod. The eccentric part of the eccentric handle abuts against the housing, so that when the eccentric handle swings, it pulls the pull rod to create negative pressure on the suction cup. An adhesive layer is provided on the back of the suction cup; the housing is inserted into the mounting position from back to front and locked from front to back by a locking member.

[0005] The present invention is further configured such that the eccentric component of the eccentric handle is hinged to the pull rod by a hinge pin, and the hinge pin is detachable.

[0006] The present invention is further configured such that the hinge pin is arranged horizontally; the eccentric handle is provided with an ejection hole for an external strip to be inserted to eject the hinge pin.

[0007] The present invention is further configured such that the mounting position is hole-shaped, and the side of the mounting position facing the rear end of the fixing seat is provided with a stepped groove, and the inner wall of the stepped groove is provided with a positioning key; the outer wall of the housing is provided with a retaining flange that is adapted to and abuts the stepped groove, and the retaining flange is provided with a positioning groove that is adapted to the positioning key to form a circumferential positioning; the side of the retaining flange facing the front of the housing is provided with a first thread; the first thread passes through the mounting position and engages with the thread of the locking member.

[0008] The present invention is further configured such that the first thread is an external thread, and the locking member is annularly screwed into the first thread while abutting against the end face of the mounting position side.

[0009] The present invention is further configured such that an upper protrusion is provided at the front of the housing above its center position, and the pull rod extends from the center position of the front of the housing and is hinged to the eccentric handle; the eccentric handle is located below the upper protrusion, and the eccentric handle, when flipped down, forms an outward protrusion structure with the upper protrusion that protrudes outward from the locking member.

[0010] The present invention is further configured such that a flip-out groove is provided on the lower side of the eccentric handle, and the flip-out groove is exposed outside the locking member.

[0011] The present invention is further configured such that the placement seat is located on the front of the fixed seat.

[0012] The present invention is further configured such that there are multiple storage seats, which are spaced apart along the height direction of the fixed seat.

[0013] The present invention is further configured such that the storage seat is a hinged seat.

[0014] The beneficial effects of this utility model are:

[0015] 1. When the eccentric handle is flipped down, it forms an outward convex structure together with the upper protrusion, enhancing the overall aesthetics.

[0016] 2. Fixation is achieved through negative pressure adsorption and adhesive layer adhesion, which has the advantages of high firmness and stability. It also has low requirements for the smoothness of the surface to be fixed, and the initial adsorption provides a good environment for the adhesive layer to be applied.

[0017] 3. By making the suction cup assembly and the mounting base detachable, the problem of the traditional suction cup shelf base with adhesive layer being unable to be removed after being fixed is avoided. When it is necessary to move the shelf, simply remove the mounting base and replace it with a new suction cup assembly (for users with weak hands-on skills or users who do not care that the suction cup assembly cannot be removed).

[0018] 4. By setting a detachable suction cup, the auxiliary parts of the suction cup assembly can be removed, leaving only the suction cup. This makes it easy for users to lift the suction cup from the edge and tear it off the fixed surface (for users with high hands-on ability or users who are concerned about the inability to remove the suction cup assembly).

Detailed Implementation

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] refer to Figures 1 to 10 ,like Figures 1 to 10The illustrated flip-type shelf base includes a fixed base 10, on which a shelf 11 and a mounting position 12 are provided. The mounting position 12 is provided with a suction cup assembly 20. The suction cup assembly 20 includes a housing 21, with a suction cup 22 on the back of the housing 21. The suction cup 22 has a pull rod 221 that passes through the housing 21. The front of the housing 21 has an eccentric handle 23 that is hinged to the pull rod 221. The hinge axis of the eccentric handle 23 and the pull rod 221 is perpendicular to the axis of the pull rod 221. The eccentric part 231 of the eccentric handle 23 abuts against the housing 21, so that when the eccentric handle 23 swings, it pulls the pull rod 221, causing the suction cup 22 to form a negative pressure. The back of the suction cup 22 is provided with an adhesive layer 222. The housing 21 is inserted into the mounting position 12 from back to front and locked from front to back by a locking member 24.

[0032] In the above structure, since the suction cup 22 with adhesive layer 222 cannot be directly removed after being fixed and the negative pressure is released, the suction cup assembly 20 and the fixing base 10 are set to be detachable. The suction cup assembly 20 is used as a replacement part. When the shelf (not shown in the figure) needs to be moved along with the fixing base 10, the locking part 24 is loosened to separate the fixing base 10 from the housing 21 of the suction cup assembly 20, and then a new suction cup assembly 20 is installed to achieve off-site installation. The eccentric handle 23 is hinged to the pull rod 221. When it swings, the eccentric part 231 on the eccentric handle 23 abuts against the housing 21 to pull the pull rod 221, thus achieving reliable installation.

[0033] In this embodiment, the eccentric part 231 of the eccentric handle 23 is hinged to the pull rod 221 by a hinge pin 25, and the hinge pin 25 is detachable.

[0034] In the above structure, since replacing the entire suction cup assembly 20 is costly (the suction cup 22 cannot be lifted off the edge due to the obstruction of the housing 21), the suction cup 22 can be replaced separately according to the user's needs (hands-on ability). The suction cup 22 is separated from the housing 21 and the eccentric handle 23 by the hinge pin 25. At this time, only the suction cup 22 is attached to the surface to be fixed. The suction cup 22 can be removed by simply lifting the edge of the suction cup 22 and forcefully pulling it off to remove the adhesive layer 222 from the surface to be fixed. Then, the new suction cup 22 can be reassembled.

[0035] In this embodiment, the hinge pin 25 is arranged horizontally; the eccentric handle 23 is provided with an ejection hole 232 for an external strip to be inserted to eject the hinge pin 25.

[0036] In the above structure, the horizontally arranged hinge pin 25 ensures that the swing direction of the eccentric handle 23 is up and down. When the handle is in the downward swing state, pulling the lever 221 can use its own weight to ensure the position of the eccentric handle 23. The ejection hole 232 facilitates the removal of the hinge pin 25 by pushing it out through an external strip, which provides convenience for the replacement of the suction cup 22.

[0037] In this embodiment, the mounting position 12 is hole-shaped, and a stepped groove 121 is provided on the side of the mounting position 12 facing the rear end of the fixing seat 10. A positioning key 122 is provided on the inner wall of the stepped groove 121. A retaining flange 211 is provided on the outer wall of the housing 21 to fit and abut against the stepped groove 121. The retaining flange 211 is provided with a positioning groove 212 that fits to the positioning key 122 to form a circumferential positioning. A first thread 213 is provided on the side of the retaining flange 211 facing the front of the housing 21. The first thread 213 passes through the mounting position 12 and is threadedly engaged with the locking member 24.

[0038] In the above structure, the positioning key 122 and the positioning groove 212 are adapted to prevent the housing 21 from rotating when the locking member 24 is rotated to lock.

[0039] In this embodiment, the first thread 213 is an external thread, and the locking member 24 is annularly screwed into the first thread 213 while abutting against the end face on the mounting position 12 side.

[0040] In the above structure, the locking member 24 is a locking ring, which fixes the housing 21 to the fixed seat 10 by engaging with the first thread 213.

[0041] In this embodiment, the housing 21 has an upper protrusion 214 at a position higher than its center. The pull rod 221 extends from the center of the front of the housing 21 and is hinged to the eccentric handle 23. The eccentric handle 23 is located below the upper protrusion 214. When the eccentric handle 23 is flipped down, it forms an outward protrusion structure 210 with the upper protrusion 214 that protrudes outward from the locking member 24.

[0042] In the above structure, the eccentric handle 23 is flipped down to form an outward convex structure 210 together with the upper protrusion 214, which enhances the overall aesthetics.

[0043] In this embodiment, the eccentric handle 23 is provided with a flip-out groove 233 on the lower side, and the flip-out groove 233 is exposed outside the locking member 24.

[0044] In the above structure, it is easy to insert the fingers when the eccentric handle 23 is flipped up to release the tension on the pull rod 221.

[0045] In this embodiment, the storage seat 11 is located on the front of the fixed seat 10.

[0046] In the above structure, the storage seat 11 can also be located on the side of the fixed seat 10.

[0047] In this embodiment, there are multiple placement seats 11, which are spaced apart along the height direction of the fixed seat 10.

[0048] In the above structure, multiple connection points are provided for the shelf (not shown in the figure).

[0049] In this embodiment, the storage seat 11 is a hinged seat.

[0050] The above structure facilitates hinge connection with a shelf (not shown in the figure), enabling the shelf (not shown in the figure) to have an upward-folding storage function.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
