Description

Technical Field

[0001] This utility model relates to the field of photographic equipment, and in particular to a vacuum suction cup and bracket. Background Technology

[0002] Vacuum soft rubber suction cups are widely used for fixing or suspending items, especially non-powered vacuum soft rubber suction cups. They typically use soft rubber as the suction element, generating a low-pressure suction force by expelling air from between the soft rubber and the surface. When the soft rubber is lifted, air re-enters between the soft rubber and the surface, restoring the pressure to normal, thus allowing the vacuum soft rubber suction cup to be quickly removed. However, existing vacuum soft rubber suction cups have the following drawbacks:

[0003] 1. The soft rubber is completely exposed on the side of the shell, making the edges of the software easily touched, which can cause vacuum failure and lead to the soft rubber suction cup accidentally falling off.

[0004] 2. The unreasonable structural design of the soft rubber results in insufficient vacuum, which in turn makes the suction power of the soft rubber suction cup insufficient and unable to support the suspension of heavy items.

[0005] Therefore, there is an urgent need for a vacuum suction cup and bracket to solve the above problems. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a vacuum suction cup and a support.

[0029] Reference Figures 1 to 3 This utility model provides a vacuum suction cup, including a screw cap 10 and a soft rubber suction cup 20;

[0030] The lower edge of the screw cap 10 is provided with an annular retaining ring 11, which forms a receiving groove 12. The inner top wall of the receiving groove 12 is provided with a first threaded groove 13.

[0031] The soft rubber suction cup 20 is located inside the receiving groove 12 and the outer wall portion is opposite to the annular retaining ring 11. The upper end of the soft rubber suction cup 20 is provided with a threaded post 30 connected to the first threaded groove 13, and the lower end is provided with an adsorption groove 40.

[0032] The threaded column 30 can push the soft rubber suction cup 20 when the cap 10 rotates relative to the soft rubber suction cup 20, so that the air in the suction groove 40 is discharged and a suction force is generated.

[0033] In this utility model, during assembly, the threaded post 30 on the soft rubber suction cup 20 is threaded into the first threaded groove 13 on the cap 10 until the soft rubber suction cup 20 and the cap 10 abut together. During use, the suction cup is placed on the surface to be suctioned, allowing the soft rubber suction cup 20 to adhere to the surface. Then, the cap 10 is rotated relative to the soft rubber suction cup 20. The engagement of the threaded post 30 and the first threaded groove 13 pushes the soft rubber suction cup 20, causing the air in the suction groove 40 at the lower end of the soft rubber suction cup 20 to be expelled, creating a low-pressure suction between the soft rubber suction cup 20 and the surface, ultimately allowing the suction cup to adhere to the surface. When the suction cup needs to be removed, it is pressed until the suction groove 40 reconnects with the outside, the internal and external air pressures are balanced, and the soft rubber suction cup 20 loses its suction force and detaches from the surface, thus removing the suction cup. It should be noted that, referring to... Figure 3 The height of the annular retaining ring 11 is H1, and the height between the lower end face of the annular retaining ring 11 and the plane is H2, so that the user can fasten the soft rubber suction cup 20 through the area indicated by H2, thereby removing the suction cup.

[0034] Reference Figures 1-3 In some embodiments, the soft rubber suction cup 20 includes a push block 21, a connecting ring 22, and a pressing ring 23. The inner ring of the connecting ring 22 is connected to the push block 21, and the outer ring is connected to the pressing ring 23. A threaded post 30 is disposed on the upper end face of the push block 21. The annular retaining ring 11 is opposite to the outer wall of the pressing ring 23. The adsorption groove 40 is formed on the lower end face of the push block 21, the connecting ring 22, and the pressing ring 23. When the cap 10 is rotated, the push block 21 will be pushed downward by the cooperation of the threaded post 30 and the first threaded groove 13. When the push block 21 moves, it will cause the connecting ring 22 to deform, thereby squeezing the air in the adsorption groove 40 outward and generating a low-pressure adsorption force.

[0035] Reference Figures 1-3 In some embodiments, a first pressure ring 51 and a second pressure ring 52 are provided on the screw cap 10 from the inside to the outside. The first pressure ring 51 abuts against the upper end face of the connecting ring 22, and the second pressure ring 52 abuts against the upper end face of the pressing ring 23. This arrangement enables the pressing ring 23 to remain in contact with the plane during the rotation of the screw cap 10, which is beneficial to improving the stability of adsorption.

[0036] Reference Figures 1-3In some embodiments, a first mounting groove 61 is provided on the inner top wall of the receiving groove 12, and a first metal connecting sleeve 62 is provided in the first mounting groove 61. A first threaded groove 13 is formed on the first metal connecting sleeve 62. Preferably, a first adhesive groove 63 is provided on the outer wall of the first metal connecting sleeve 62 so that the first metal connecting sleeve 62 is glued to the first mounting groove 61. During assembly, glue is applied to the first mounting groove 61. When the first metal connecting sleeve 62 is placed into the first mounting groove 61, the glue will seep into the first adhesive groove 63, thereby improving the firmness of the connection between the first metal connecting sleeve 62 and the first mounting groove 61.

[0037] Reference Figures 1-3 In some embodiments, the upper end face of the screw cap 10 is provided with a second mounting groove 71, a second metal connecting sleeve 72 is provided in the second mounting groove 71, and a second threaded groove 73 is provided on the second metal connecting sleeve 72 for engaging the threaded rod 90; preferably, a second adhesive groove 74 is provided on the outer wall of the second metal connecting sleeve 72 so that the second metal connecting sleeve 72 is adhesively bonded to the second mounting groove 71; during assembly, glue is applied to the second mounting groove 71, and when the second metal connecting sleeve 72 is placed into the second mounting groove 71, the glue will seep into the second adhesive groove 74, thereby improving the firmness of the connection between the second metal connecting sleeve 72 and the second mounting groove 71.

[0038] Reference Figures 1-3 In some embodiments, an anti-slip structure 80 is provided on the outer wall of the screw cap 10, which can increase the friction between the screw cap 10 and the user's palm and improve the ease of rotating the screw cap 10.

[0039] Reference Figures 1-3 In some embodiments, the screw cap 10 is made of hard plastic.

[0040] This utility model also provides a bracket, including the aforementioned vacuum suction cup.

[0041] The advantages of this invention are as follows: the above structure not only allows the suction cup to adhere to a smooth surface, but also prevents the soft rubber suction cup from accidentally loosening and falling off. At the same time, the vacuum adsorption method using the soft rubber suction cup can avoid sticky residue on the surface, improving the convenience and safety of use.

[0042] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
