Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of suction accessories, in particular to a kind of multifunctional detachable suction disc. BACKGROUND

[0002] Suction disc is usually made of soft rubber or silicone material, which can be closely attached to various smooth surfaces. When the suction disc is pressed on a smooth surface, the air inside the suction disc is discharged, forming a near-vacuum state. Once a vacuum or low pressure is formed inside the suction disc, the atmospheric pressure outside the suction disc will act on the suction disc, pressing it tightly against the surface. This pressure difference allows the suction disc to be firmly attached to the object. Suction disc is easy to install, reusable and does not damage the surface, so it is popular.

[0003] The existing design of suction disc usually has a suction pad and a connecting part. The connecting part is used to connect the matching product. The existing suction disc has the following problems:

[0004] 1. The suction body and the connecting part are fixedly connected, and they are not detachable. When one part is damaged, the entire suction disc needs to be replaced.

[0005] 2. The connection of the product is generally linear or U-shaped, but the connecting part of the existing suction disc can only be matched in one way, with low compatibility. SUMMARY

[0006] The utility model provides a kind of multifunctional detachable suction disc with high compatibility and improved service life to overcome the shortcomings of the prior art.

[0008] The utility model discloses an adsorption pad and upper cover can be detachably connected, when the adsorption pad or other parts are damaged, can take off the adsorption pad and upper cover and replace the damaged part, prolong the service life of the suction cup, in addition, the transverse connection groove group on the lower cover is used for installing linear finished products, and the U-shaped connection groove group is suitable for U-shaped products in cooperation with the limiting hole column, and the compatibility of the utility model discloses the suction cup is improved.

[0009] As preferred, the first groove and the second groove are horizontally oriented, and the third groove and the fourth groove are front-back oriented. The horizontal or vertical orientation can accommodate more different specifications of products, and the structure is more reasonable.

[0010] As preferred, the adsorption pad is fixed with a stud, and the upper cover has a nut adapted to the stud, and the stud and the nut are connected in the hollow channel. The detachable connection of the adsorption pad and the upper cover is realized by threaded connection, and the upper cover, the lower cover and the adsorption pad can be replaced to improve the service life.

[0011] Further, the annular side wall includes an upper ring part and a lower ring part, the transverse connection groove group and the U-shaped connection groove group are arranged on the upper ring part, and the lower ring part has a limiting cavity for accommodating the adsorption pad. The adsorption pad is arranged in the limiting cavity, and the limiting ring part limits the position of the adsorption pad to avoid displacement of the adsorption pad.

[0012] Further, the limiting cavity has a pressing member, and the stud is connected with the nut. When the stud and the nut are locked, the pressing member of the lower cover abuts against the surface of the adsorption pad and gradually increases the pressure applied to the adsorption pad, thereby improving the adsorption force of the adsorption pad as a whole.

[0013] Further, the limiting hole column has a limiting convex ring, and the stud is connected with the nut through the limiting convex ring. The limiting convex ring limits the bottom of the stud to make the stress of the stud more uniform and avoid deformation of the stud.

[0014] As preferred, the limiting hole column is uniformly provided with reinforcing ribs to enhance the stability of the upper cover. BRIEF DESCRIPTION OF DRAWINGS
