Description

Technical Field

[0001] The utility model relates to the technical field of sucker brackets, in particular to a sucker bracket base. Background Art

[0002] At present, sucker brackets are mainly used as fixing accessories for mobile phones, camera devices or other intelligent devices and are widely used in daily life. The existing sucker brackets are mainly fixed by suckers with adhesives adsorbed on objects.

[0003] For example, in the Chinese utility model patent No. 202221445142.5, a sucker for a bracket component discloses that nano glue is provided on the TPU positioning block of a high-temperature resistant TPU sucker, and the nano glue is used to adhere to the plane where the sucker needs to be adsorbed by utilizing the characteristics of the nano glue. Although the connection stability of the sucker can be improved by the sticking effect of the nano glue, under long-term high-temperature sunlight, the nano glue will completely adhere to the plane and is difficult to remove, resulting in the situation that it is difficult or even impossible to change the adsorption position of the sucker.

[0004] Therefore, it is urgent to research and develop a sucker bracket base to solve the defects that the adhesive viscosity of the existing sucker brackets increases under high-temperature sunlight and it is difficult to disassemble them completely from objects, and they cannot be used again even after disassembly. Summary of the Invention

[0005] The purpose of the utility model is to provide a sucker bracket base, which can improve the disassembly and assembly convenience of the sucker bracket base.

[0006] In order to achieve the above purpose, a sucker bracket base provided by the utility model has the following specific implementation schemes:

[0007] A sucker bracket base, comprising:

[0008] A seat body;

[0009] A connecting column, arranged on the seat body;

[0010] A sucker, arranged at the bottom of the seat body and connected to the bottom of the connecting column;

[0011] A protrusion, arranged at the bottom of the sucker and extending towards the side away from the seat body;

[0012] The sucker and the seat body are cooperated to form a separated state, and the connecting column is displaced in its axial direction to form a first position and a second position;

[0013] The connecting column is displaced from a first position to a second position in its axial direction, driving the connecting column to descend. The protrusion abuts against the adsorption plane of the suction cup, releasing the vacuum negative pressure in the vacuum negative pressure chamber between the suction cup and the adsorption plane, forming a detached state.

[0014] A suction cup support base of the present utility model, compared with the prior art, by arranging a connecting column on the seat body, the connecting column can be displaced in its own axial direction. The top of the connecting column is connected with a suction cup located at the bottom of the seat body, and a protrusion is arranged at the bottom of the suction cup. During actual use, when the suction cup is adsorbed on the adsorption plane and the suction cup support base needs to be disassembled, the connecting column rotates along its axial direction from the first position to the second position, driving the suction cup on the connecting column to descend. The protrusion presses against the adsorption plane, so that the vacuum negative pressure in the vacuum negative pressure chamber between the suction cup and the adsorption plane is released, and the periphery of the suction cup disengages from the adsorption plane to achieve detachment from the adsorption plane. Compared with the method of fixing with adhesive, the disassembly and assembly convenience of the suction cup support base is improved.

[0015] In some embodiments, in the natural state, the height of the protrusion is higher than the height of the adsorption plane of the suction cup.

[0016] By setting the height of the protrusion to be higher than the height of the suction cup, when the suction cup deforms and resets to the natural state, it will necessarily abut against the adsorption plane of the suction cup, causing the suction cup and the adsorption plane to disengage, improving the disengagement convenience between the suction cup support base and the adsorption plane.

[0017] In some embodiments, a skirt is provided at the bottom of the seat body, and the skirt corresponds to the outer peripheral edge of the suction cup.

[0018] By arranging a skirt at the bottom of the seat body, and the skirt corresponding to the outer peripheral edge of the suction cup, when the suction cup is pulled and deformed by the connecting column, the skirt can press against the outer peripheral edge of the suction cup, improving the adsorption stability between the suction cup and the adsorption plane.

[0019] In some embodiments, in the adsorption state, the skirt presses against the outer peripheral edge of the suction cup;

[0020] In the detached state, there is a second gap between the skirt and the suction cup or the skirt contacts the outer peripheral edge of the suction cup.

[0021] By making the skirt press against the outer peripheral edge of the suction cup in the adsorption state, the adsorption stability of the suction cup and the vacuum seal of the vacuum negative pressure chamber are improved. In the detached state, the skirt contacts the suction cup or has a second gap, and the skirt does not apply pressure to the suction cup, ensuring that the vacuum negative pressure chamber is quickly cancelled and the suction cup disengages from the adsorption plane.

[0022] In some embodiments, the protrusion is arranged at the central position of the suction cup.

[0023] By setting the protrusion at the central position of the suction cup, the deformation uniformity of the suction cup when the connecting column pulls up the suction cup during lifting is improved.

[0024] In some embodiments, a convex post is provided at the bottom of the connecting column. The convex post is disposed within the suction cup, and at least a part of the convex post is located below the suction cup, forming the protrusion.

[0025] By providing a convex post at the bottom of the connecting column, the convex post is arranged within the suction cup and is arranged such that at least a part of the convex post is located below the suction cup to form the protrusion, ensuring that the structure strength of the protrusion is improved with the cooperation of the convex post inside the protrusion, thereby enhancing the structural stability of the protrusion and ensuring that the vacuum negative pressure in the vacuum negative pressure chamber can be stably released.

[0026] In some embodiments, the connecting column and the suction cup are integrally formed.

[0027] By integrally forming the connecting column with the suction cup, the stability of the upward deformation of the suction cup driven by the lifting of the connecting column and the downward reset can be improved.

[0028] In some embodiments, a return spring is sleeved on the connecting column. One end of the return spring abuts against the suction cup, and the other end abuts against the seat body.

[0029] By sleeving a return spring on the connecting column, with one end of the return spring abutting against the suction cup and the other end abutting against the seat body, after the connecting column is lifted in its axial direction, the suction cup and the seat body cooperate to compress the return spring. When the connecting column descends and resets, the elastic restoring force of the return spring can assist in the reset of the connecting column, improving the convenience of reset.

[0030] In some embodiments, the suction cup is made of plastic or silica gel.

[0031] By setting the suction cup to be made of plastic or silica gel, the characteristics of plastic or silica gel can be utilized to improve the high temperature resistance, corrosion resistance and wear resistance of the suction cup, thereby extending the service life of the suction cup.

[0032] In some embodiments, the area of the protrusion accounts for 2% - 65% of the area of the suction cup.

[0033] By setting the area of the protrusion to account for 2% - 65% of the area of the suction cup, it is ensured that the protrusion can improve the convenience of detachment of the suction cup from the adsorption plane while the suction cup can effectively adsorb on the adsorption plane. At the same time, it is avoided that the area ratio of the protrusion is too small, resulting in the connecting column being unable to drive the deformation of the suction cup and the protrusion being unable to release the vacuum negative pressure in the vacuum negative pressure chamber, or the area ratio being too large, resulting in the interference of the protrusion between the suction cup and the adsorption plane and preventing adsorption.

[0034] Based on the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0035] By providing a connecting column on the seat body, the connecting column can displace in its own axial direction. The top of the connecting column is connected to a suction cup located at the bottom of the seat body, and a protrusion is provided at the bottom of the suction cup. During actual use, when the suction cup is adsorbed on the adsorption plane and it is necessary to disassemble the suction cup bracket base, the connecting column rotates along its axial direction and displaces from the first position to the second position, driving the suction cup on the connecting column to descend. The protrusion presses against the adsorption plane, so that the vacuum negative pressure in the vacuum negative pressure cavity between the suction cup and the adsorption plane is released, and the periphery of the suction cup is separated from the adsorption plane to achieve separation from the adsorption plane. Compared with the method of fixing with glue, the disassembly and assembly convenience of the suction cup bracket base is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] To facilitate the understanding of the utility model, the specific embodiments of the utility model will be described in more detail below with reference to the accompanying drawings of the specification.

[0043] Unless otherwise specified or defined, the "first, second..." used herein is only for distinguishing names and does not represent a specific quantity or order.

[0044] Unless otherwise specified or defined, the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0045] It should be noted that in this text, "fixed to" and "connected to" can be directly fixed or connected to a component, or indirectly fixed or connected to a component.

[0046] Embodiment 1:

[0047] As Figure 1 and 2 shown, a suction cup bracket base provided in this embodiment includes a base body 100. A suction cup 300 is provided at the bottom of the base body 100. The suction cup 300 is made of plastic or silica gel. In this embodiment, it is preferably one of a TPE suction cup, a PVC suction cup, and a silica gel suction cup. A connecting column 200 is further provided on the base body 100. The connecting column 200 penetrates the base body 100, and the bottom of the connecting column 200 is connected to the suction cup 300.

[0048] Moreover, the connecting column 200 can displace on the base body 100 in its own axial direction, driving the suction cup 300 to lift or lower.

[0049] A protrusion 310 is provided at the central position of the suction cup 300. The bottom of the protrusion 310 is located below the bottom of the suction cup 300. It can be understood that in the natural state, the height of the protrusion 310 is higher than the height of the adsorption plane of the suction cup 300.

[0050] Moreover, the area of the protrusion 310 accounts for 2% - 65% of the area of the suction cup 300.

[0051] Optionally, the connecting column 200 and the suction cup 300 are integrally formed; or the connecting column 200 and the suction cup 300 are integrally formed after secondary injection molding, so that the bottom of the connecting column 200 is wrapped by the suction cup 300.

[0052] A convex column 210 is provided at the bottom of the connecting column 200. The convex column 210 is provided inside the suction cup 300, so that a part of the connecting column and the convex column 210 are both accommodated inside the suction cup 300. At least part of the convex column 210 is located below the suction cup 300, thereby forming the protrusion 310.

[0053] A skirt 110 is provided at the bottom of the base body 100. The skirt 110 corresponds to the outer peripheral edge of the suction cup 300.

[0054] In actual use, the suction cup 300 and the base body 100 cooperate to form a detached state or an adsorbed state. The connecting column 200 displaces in its axial direction to form a first position and a second position;

[0055] The connecting column 200 is displaced from the first position to the second position in its axial direction, driving the connecting column 200 to descend. The protrusion 310 abuts against the adsorption plane of the suction cup 200, releasing the vacuum negative pressure in the vacuum negative pressure cavity between the suction cup 200 and the adsorption plane, forming a separated state.

[0056] The connecting column 200 is displaced back from the second position to the first position in its axial direction, driving the connecting column 200 to lift and pulling the suction cup 300 connected to the connecting column 200 to deform upward. There is a first gap between the protrusion 310 and the adsorption plane of the suction cup 300. The skirt 110 on the base 100 presses against the periphery of the suction cup 300, and a vacuum negative pressure cavity is formed between the suction cup 200 and the adsorption plane, forming an adsorption state.

[0057] A return spring 230 is sleeved on the connecting column 200. One end of the return spring 230 abuts against the suction cup 300, and the other end abuts against the base 100. After the connecting column 200 is lifted in its axial direction, the suction cup 300 and the base 100 cooperate to compress the return spring 230, so that when the connecting column 200 descends and resets, the elastic restoring force of the return spring 230 can assist the reset of the connecting column 200, improving the convenience of reset.

[0058] Embodiment 2:

[0059] As Figure 3 and 4 shown, on the basis of Embodiment 1, this embodiment further provides a rotatable rotating member 400 at the top of the base 100. The rotating member 400 has a hollow structure, and two oppositely arranged lifting tracks 410 are provided at the top of the rotating member 400. The lifting tracks 410 have a first positioning portion 411 and a second positioning portion 412, and the heights of the first positioning portion 411 and the second positioning portion 412 are different. A lifting rod 220 is provided at the top of the connecting column 200. The lifting rod 220 is mounted on the rotating member 400, and both ends of the lifting rod 220 extend into the corresponding lifting tracks 410.

[0060] An installation cover 500 is provided on the base 100. The installation cover 500 covers the rotating member 400, the connecting column 200, and the lifting rod 220. A swinging groove 510 penetrating through itself is opened in the installation groove. A swinging rod 420 is provided on the outer wall of the rotating member 400. The swinging rod 420 passes through the swinging groove 510 and extends outside the installation cover 500.

[0061] During actual use, the user turns the swing rod 420, causing the rotating member 400 to rotate. The lifting rod 220 moves from the positioning part at a lower height to the positioning part at a higher height, thereby driving the connecting column 200 to lift in its axial direction. The upper suction cup 300 deforms upward, and the skirt 110 presses against the outer peripheral edge of the suction cup 300, causing a vacuum negative pressure cavity to be formed between the suction cup 300 and the adsorption plane to complete adsorption.

[0062] Conversely, the swing rod 420 is turned in the opposite direction to reset the rotating member 400. The lifting rod 220 moves from the positioning part at a higher height to the positioning part at a lower height, driving the connecting column 200 to descend and reset in its axial direction. The suction cup 300 and the protrusion 310 are reset with the assistance of the return spring 230. The protrusion 310 abuts against the adsorption plane, and the skirt 110 no longer presses against the outer peripheral edge of the suction cup 300, releasing the vacuum negative pressure in the vacuum negative pressure cavity between the suction cup 300 and the adsorption plane to complete the detachment of the suction cup 300 from the adsorption plane.

[0063] Based on the disclosure and teachings of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
