[0003] There are many types of suction cup fixing devices, such as press type, lever type, inclined wedge rotation type, inclined wedge push type, and thread rotation type. The lever type uses a lever mechanism to lift the suction cup, thereby forming a negative pressure space between the suction cup and the external support surface, thereby forming the static friction required for fixation.

[0004] The Chinese invention patent publication with the announcement number CN106321610A and the name of the suction cup assembly discloses a lever-type suction cup fixing device, which is detachably connected to the cover 7 through the body 2. The end surface of the cover 7 is provided with a storage box 8 to expand the range of items that can be stored, and the limit of the cover 7 can also prevent the handle 4 used as a lever from being accidentally opened. However, the convex strip 24 and the outer flange 25 used for engaging with the card slot 71 of the cover 7 in the prior art are both formed on the body 2. The gravity of the stored items is mainly transmitted to the body 2 through the cover 7, but the edge of the rear end of the body 2 will inevitably scratch the suction sheet 1, thereby causing the suction sheet 1 to be partially deformed too much and leak or fall off.

[0029] DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Reference Figures 1 to 6 In one embodiment, the suction cup fixing device 100 proposed in the present application includes a mounting seat 10, a suction cup member 20 and a pull button 30, wherein:

[0032] The rear end of the mounting seat 10 is formed with a support ring 11, the middle part is provided with a connecting hole 12 which passes through the front and rear parts, and the front side surface is formed with a fulcrum contact surface 13;

[0033] The suction cup member 20 includes a flexible cup 21 and a connecting rod 22 extending forward from the middle of the flexible cup 21. The flexible cup 21 is located at the rear side of the mounting seat 10. The connecting rod 22 is passed through the connecting hole 12 and protrudes from the front side of the mounting seat 10.

[0034] The pull button 30 protrudes from the front side of the mounting seat 10 , and the pull button 30 is rotatably connected to the front end of the connecting rod 22 and can movably abut against the fulcrum contact surface 13 , and the end of the pull button 30 away from the mounting seat 10 forms a clamping guide rail 32 .

[0035] In this embodiment, the mounting seat 10 is used to provide support and protection, and the support ring 11 can contact the external support surface or be used to constrain the deformation of the flexible disk 21, so that it can better produce uniform deformation, thereby forming a more stable negative pressure chamber. The flexible disk 21 is usually supported by flexible materials such as silicone and rubber. In order to better fit the external support surface, materials such as adhesives can also be set on the attachment surface of the flexible disk 21. This can not only provide initial adhesion but also fill the tiny gaps on the external support surface, thereby ensuring the stability of adsorption. The connecting rod 22 is usually rotatably connected to the pull buckle 30 in a pivoted manner. Preferably, an independent hard material such as a steel pin is provided to connect the pull buckle 30 and the connecting rod 22. The snap-in guide rail 32 can be a convex strip, a slot, or a combination of a convex strip and a slot. The snap-in guide rail 32 can be conveniently snapped with the external container, for example, in a plug-in manner.

[0036] The suction cup fixing device 100 of the utility model is provided with a snap-on guide rail 32 for connecting to an external container on the pull button 30, so that the gravity of the stored items is mainly transmitted to the suction cup member 20 through the pull button 30, and the mounting seat 10 is equivalent to being suspended on the connecting rod 22, which will not squeeze the edge of the flexible disk 21, that is, it will not have an adverse effect on the stable adsorption of the suction cup member 20. In addition, because the pull button 30 protrudes from the front side of the mounting seat 10, and the snap-on guide rail 32 is located at the end of the pull button 30 away from the mounting seat 10, a larger installation space can be formed between the snap-on guide rail 32 and the front side of the mounting seat 10, so that it can better adapt to external containers of different shapes, thereby improving the versatility of the suction cup fixing device 100.

[0037] Further, refer to Figure 2 , Figure 3 as well as Figure 5 The pull button 30 includes a cover plate 31 and two cams 35 arranged on the rear side of the cover plate 31. The two cams 35 are in the shape of long strips. The sides of the two cams 35 are arranged opposite to each other. The front end of the connecting rod 22 is located between the two cams 35. One end of the cam 35 is rotatably connected to the front end of the connecting rod 22 and can be movably abutted against the fulcrum contact surface 13. The clamping guide rail 32 is formed on the edge of the cover plate 31.

[0038] In this embodiment, the cam 35 and the cover plate 31 of the pull button 30 are both plate-shaped, and the front end of the connecting rod 22 is located between the two cams 35, so that the structure becomes compact and lightweight.

[0039] Furthermore, the edge of the cover plate 31 protrudes from the outer side surfaces of the two cams 35 , and the clamping guide rail 32 includes two tangential guide rails 321 protruding from the outer side surfaces of the cams 35 respectively.

[0040] In this embodiment, the clamping guide rail 32 includes two tangential guide rails 321, so that the external container can generate a large limiting force to prevent the pull button 30 from turning outward after being clamped with the two tangential guide rails 321. Specifically, when the two cams 35 extend in the up-down direction, the external container can be clamped with the two tangential guide rails 321 in the up-down direction. In this way, after the external container is installed, the lower end of the pull button 30 needs to overcome the force arm corresponding to the gravity of the external object to turn upward.

[0041] Furthermore, the cover plate 31 includes an axial support surface 34 formed between the two tangential guide rails 321, so that a better limiting and supporting effect can be formed, so that the external container is not prone to shaking after being installed in place.

[0042] Further, refer to Figure 2 , Figure 4 as well as Figure 6The edge of the cover plate 31 protrudes from the outer end surfaces of the two cams 35 , and the clamping guide rail 32 includes two axial guide rails 322 protruding from the end surfaces of the cams 35 respectively.

[0043] In this embodiment, the clamping guide rail 32 includes two axial guide rails 322 , so that the external container can be clamped with the two axial guide rails 322 along the rotation axis of the buckle 30 .

[0044] Furthermore, the cover plate 31 includes a tangential support surface 33 formed between the two axial guide rails 322, which has the same function as the axial support surface 34. This setting can form a better limiting and supporting effect, so that the external container is not prone to shaking after being installed in place.

[0045] Furthermore, the trigger 30 further includes an axial rib 36 , which connects ends of the two cams 35 away from the connecting rod 22 and is connected to the cover plate 31 .

[0046] In this embodiment, the axial ribs 36 can simultaneously increase the structural strength of the cam 35 and the cover plate 31 , thereby improving the reliability of the normal operation of the buckle 30 .

[0047] Further, refer to Figures 2 to 4 ,as well as Figure 6 A clamping structure 39 is provided at one end of the pull button 30 away from the connecting rod 22 , and the mounting seat 10 is provided with a clamping matching structure 14 clamped with the clamping structure 39 .

[0048] In this embodiment, the end of the pull buckle 30 away from the connecting rod 22 is engaged with the mounting seat 10 to ensure that it is not prone to accidental popping open during the installation and / or removal of the external container, thereby ensuring the stability of the adsorption fixation.

[0049] Furthermore, the pull buckle 30 includes a cam 35, a eaves plate 37 and a surrounding plate 38. The eaves plate 37 is connected to the periphery of the cam 35. When the pull buckle 30 is in a buckled state, the eaves plate 37 is arranged opposite to the front side of the mounting seat 10; the surrounding plate 38 is formed by extending backward from the edge of the eaves plate 37, and the snap-fit ​​structure 39 is an elastic snap formed on the surrounding plate 38; the snap-fitting structure 14 is a snap hole opened on the front side of the mounting seat 10.

[0050] In this embodiment, the eaves plate 37 and the enclosure plate 38 can both enhance the structural strength of the pull buckle 30, and by setting the snap-fit ​​structure 39 as an elastic snap buckle formed on the enclosure plate 38, not only can the structural strength of the pull buckle 30 be ensured, so that the pull buckle 30 can lift the flexible disk 21 to form a negative pressure cavity with a large pressure difference, but it is also convenient to open the pull buckle 30 to release the negative pressure cavity, thereby moving the suction cup fixing device 100 and changing its installation position.

[0051] Furthermore, there are two cams 35 and both are in the shape of long strips, the side surfaces of the two cams 35 are arranged opposite to each other, the front end of the connecting rod 22 is located between the two cams 35, one end of the cam 35 is rotatably connected to the front end of the connecting rod 22 and can movably abut against the fulcrum contact surface 13; the two cams 35 both protrude from the front side surface of the eaves plate 37; the pull buckle 30 also includes a cover plate 31 covering and connected to the front side surfaces of the two cams 35, and a snap-in guide rail 32 is formed on the edge of the cover plate 31.

[0052] In this embodiment, the cam 35 of the pull button 30 and the cover plate 31 are both plate-shaped, and the front end of the connecting rod 22 is located between the two cams 35, so that the structure becomes compact and lightweight. The clamping guide rail 32 is formed at the edge of the cover plate 31, which can not only increase the distance between the clamping guide rail 32 and the front side of the mounting seat 10, but also form a clamping groove for clamping between the edge of the cover plate 31 and the eaves plate 37, so that the clamping connection is more stable.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
