Description

Technical Field

[0001] This utility model relates to the field of fixing bathroom products, specifically to a suction cup fixing seat. Background Technology

[0002] Suction cup mounts are widely used in various shelves (including but not limited to towel racks, bath towel racks, tissue racks, triangular baskets, etc.). In existing suction cup mounts, the suction cup is located behind the mounting bracket. A control component located in front of the mounting bracket pulls a lever to generate suction force, at which point the suction cup and the surface of the object being attracted are tightly connected. The mounting bracket and the suction cup are only restricted by the friction between them and the lever hole on the mounting bracket. Therefore, the mounting bracket is prone to wobbling around the lever hole as the axis, resulting in low overall stability. At the same time, the current lever is integrated with the suction cup through injection molding / glue injection. When the control component pulls the lever, excessive displacement of the lever can easily cause tearing between the lever and the suction cup. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a suction cup holder with strong stability and effective protection against suction cup tearing.

[0004] To address the above problems, the following technical solution is provided: a suction cup mounting base, including a fixing bracket, a suction cup mounting position on the back of the fixing bracket, a suction cup mounted on the suction cup mounting position, the back of the suction cup being an adsorption surface, a pull rod passing through the fixing bracket on the front of the suction cup, and a control component on the front of the fixing bracket for pulling the pull rod to cause the adsorption surface to be concave and generate adsorption force; the suction cup includes a cup body and a suction cup bracket, the suction cup bracket including a pull plate integrally connected to the pull rod, the pull plate and the cup body being embeddedly connected during the injection molding of the cup body, the suction cup mounting position being concave, its bottom having an annular positioning edge protruding towards the back of the fixing bracket and concentrically arranged with the pull rod and the suction cup, the annular positioning edge having an opening at the 6 o'clock position; when the suction cup is pulled by the pull rod to adsorb, its front abuts against the annular positioning edge and its opening.

[0005] The present invention is further configured such that the rotation radius of the annular positioning edge is greater than the rotation radius of the pull plate.

[0006] The present invention is further configured such that the suction cup mounting position is also provided with an annular support edge that protrudes towards the back of the fixed bracket, is concentrically arranged with the annular positioning edge, and is located inside the annular positioning edge; the rotation radius of the annular support edge is equal to or less than the rotation radius of the pull plate.

[0007] The present invention is further configured such that the fixed bracket has a pull rod hole for the pull rod to pass through, and a hanging gap is left between the upper side of the pull rod and the upper wall of the pull rod hole.

[0008] The present invention is further configured such that the control component is an eccentric handle or a locking handwheel.

[0009] The present invention is further provided that the suction cup has an adhesive layer on its adsorption surface.

[0010] The present invention is further configured such that a positioning flange is provided at the outer edge of the side of the suction cup facing the front of the fixed bracket, and the positioning flange covers the fixed bracket outside the suction cup mounting position.

[0011] The present invention is further configured such that an auxiliary positioning edge is provided on the outer side of the annular positioning edge, and an annular groove corresponding to the auxiliary positioning edge is provided on the side of the disc body facing the front of the fixed bracket; when the suction cup adsorbs, the auxiliary positioning edge is stuck in the annular groove.

[0012] The present invention is further provided that the bottom of the fixed bracket is provided with a mounting part.

[0013] The beneficial effects of this utility model are:

[0014] 1. When the disc is pulled by the tie rod, the side of the disc facing the fixed bracket will approach and abut against the annular positioning edge. At this time, due to the existence of the opening, the disc at the opening will move further towards the front of the fixed bracket, thus forming a non-rotating structure of the disc. By abutting against the opening, the adhesion between the disc and the fixed bracket is improved (specifically, the swing is formed around the center of the disc as the axis), avoiding the situation where the tie rod is twisted due to the relative displacement between the fixed bracket and the disc when the fixed bracket swings.

[0015] 2. When the pull rod moves, the disc body can abut against the annular support edge at the position corresponding to the pull plate, so as to avoid excessive displacement of the pull rod causing tearing at the connection between the pull plate and the disc body;

[0016] 3. When the fixed bracket is under force, it will move downward relative to the disc body. The hanging gap can prevent the tie rod hole and tie rod from making supporting contact in this state, thereby ensuring that the opening of the annular positioning edge can reliably contact and fix the disc body.

[0017] 4. The adhesive layer improves sealing and adhesion, making the suction cup more firmly attached during suction.

[0018] 5. The positioning flange further improves the concentricity between the two and reduces displacement;

[0019] 6. The auxiliary positioning edge and the annular groove can effectively improve the concentricity and load-bearing capacity between the disc and the fixed bracket. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of this utility model will be further described in 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 the scope of this utility model.

[0028] refer to Figures 1 to 6 ,like Figures 1 to 6 A suction cup holder shown includes a fixing bracket 10. The fixing bracket 10 has a suction cup mounting position 11 on its back, and a suction cup 20 is mounted on the suction cup mounting position 11. The back of the suction cup 20 is an adsorption surface. The front of the suction cup 20 has a pull rod 21 that passes through the fixing bracket 10. The front of the fixing bracket 10 has a control component 22 for pulling the pull rod 21 to cause the adsorption surface to be concave, generating an adsorption force. The suction cup 20 includes a cup body 23 and a suction cup support 24. The suction cup support 24 includes... The pull plate 25 is integrally connected to the pull rod 21. The pull plate 25 and the plate body 23 are embedded and connected during the injection molding of the plate body 23. The suction cup mounting position 11 is recessed and has an annular positioning edge 111 that protrudes towards the back of the fixed bracket 10 and is concentrically arranged with the pull rod 21 and the suction cup 20. The annular positioning edge 111 has an opening 112 at the 6 o'clock position. When the suction cup 20 is pulled and adsorbed by the pull rod 21, its front side abuts against the annular positioning edge 111 and its opening 112.

[0029] In the above structure, when the disc 23 is pulled by the pull rod 21, the side of the disc facing the front of the fixed bracket 10 will approach and abut against the annular positioning edge 111. At this time, due to the presence of the opening 112, the disc 23 at the opening 112 will move further towards the front of the fixed bracket 10, thereby forming a non-rotating structure of the disc 23. By abutting against the opening 112, the adhesion between the disc 23 and the fixed bracket 10 is improved (specifically, the swing is formed with the center of the disc 23 as the axis), avoiding the situation where the pull rod 21 is twisted due to the relative displacement between the fixed bracket 10 and the disc 23 when the fixed bracket 10 swings.

[0030] In this embodiment, the rotation radius of the annular positioning edge 111 is greater than the rotation radius of the pull plate 25.

[0031] In the above structure, the area of ​​the pull plate 25 has basically no deformation. Setting the rotation radius of the annular positioning edge 111 to be greater than the rotation radius of the pull plate 25 can ensure that the deformation area of ​​the plate body 23 during adsorption can be adapted to the annular positioning edge 111.

[0032] In this embodiment, the suction cup mounting position 11 is further provided with an annular support edge 113 that protrudes towards the back of the fixed bracket 10, is concentrically arranged with the annular positioning edge 111, and is located inside the annular positioning edge 111; the rotation radius of the annular support edge 113 is equal to or less than the rotation radius of the pull plate 25.

[0033] In the above structure, when the pull rod 21 moves, the disc body 23 corresponding to the position of the pull plate 25 can abut against the annular support edge 113, so as to avoid excessive displacement of the pull rod 21 causing tearing at the connection between the pull plate 25 and the disc body 23.

[0034] In this embodiment, the fixed bracket 10 is provided with a pull rod hole 12 for the pull rod 21 to pass through, and a hanging gap 13 is left between the upper side of the pull rod 21 and the upper wall of the pull rod hole 12.

[0035] In the above structure, when the fixed bracket 10 is under force, it will move downward relative to the disc body 23. The hanging gap 13 can prevent the tie rod hole 12 and the tie rod 21 from making supporting contact in this state, thereby ensuring that the opening 112 of the annular positioning edge 111 can reliably contact and fix with the disc body 23.

[0036] In this embodiment, the control component 22 is an eccentric handle or a locking handwheel.

[0037] In the above structure, the control component 22 is existing technology, and is preferably an eccentric handle.

[0038] In this embodiment, an adhesive layer 26 is also provided on the adsorption surface of the suction cup 20.

[0039] In the above structure, the adhesive layer 26 can improve the sealing and adhesion, making the suction cup 20 more firmly attached during adsorption.

[0040] In this embodiment, the suction cup 20 has a positioning flange 27 on its outer edge facing the front of the fixed bracket 10, and the positioning flange 27 covers the fixed bracket 10 outside the suction cup mounting position 11.

[0041] In the above structure, the concentricity between the two is further improved, and the displacement is reduced.

[0042] In this embodiment, an auxiliary positioning edge 114 is also provided on the outer side of the annular positioning edge 111, and an annular groove 28 corresponding to the auxiliary positioning edge 114 is provided on the side of the disc body 23 facing the front of the fixed bracket 10; when the suction cup 20 adsorbs, the auxiliary positioning edge 114 is stuck in the annular groove 28.

[0043] The above structure effectively improves the concentricity and load-bearing capacity between the disc body 23 and the fixed support 10.

[0044] In this embodiment, the protrusion heights of the auxiliary positioning edge 114, the annular positioning edge 111, and the annular support edge 113 decrease in that order.

[0045] The above structure effectively ensures the overall shape of the disk 23 during adsorption.

[0046] In this embodiment, the bottom of the fixed bracket 10 is provided with a mounting part 14.

[0047] In the above structure, the mounting part 14 is used to connect items such as mounting racks.

[0048] 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.
