Problems solved by technology

When in use, because the two circular inserts of the suction cup are integrally designed with the suction part, they cannot be separated. Between the shaped block and the suction part, the actual operation is laborious, and it is easy to damage the suction cup parts, especially in winter when the temperature is low. Rust will affect the appearance of the product. Moreover, there will be burrs on the surface of the metal ring, which will easily pierce the sunshade itself and reduce the service life of the sunshade

Example Embodiment

[0025] Example one:

[0026] Such as Figure 1 ~ Figure 4 As shown, the suction cup includes a suction part 3 and a first supporting surface 1 and a second supporting surface 2 arranged on the suction part 3 from top to bottom;

[0027] Among them, the suction part 3 is similar to the suction part on an ordinary suction cup, and can be adsorbed on a smooth surface. The suction part 3 and the second supporting surface 2 are integrally manufactured, and the surface of the first supporting surface 1 is provided with a pull ring 13 ;

[0028] The first supporting surface 1 and the second supporting surface 2 are movably connected together by a threaded connection. Specifically, a convex threaded connection column 11 is provided at the center of the bottom of the first supporting surface 1, and The surface of the second supporting surface 2 is correspondingly provided with a screw hole 21, and the threaded connecting column 11 can be screwed into the screw hole 21 to realize the movable...

Example Embodiment

[0031] Embodiment two:

[0032] Such as Figure 5 As shown, the difference between this embodiment and the first embodiment is that: the surface of the first supporting surface 1 is provided with a "one"-shaped fastening groove 14. In specific use, the first supporting surface is replaced by an external screwdriver. 1 tighten onto the second supporting surface 2.

Abstract

The invention relates to a suction disc, which is positioned at the position of a small hole of a mounting piece. The suction disc comprises a suction part (3), wherein a first supporting surface (1) and a second supporting surface (2), which are greater than the small hole, are arranged on the suction part (3) in turn from top down; a connecting piece which corresponds to the small hole and can make the first supporting surface (1) and the second supporting surface (2) joint tightly is arranged between the first supporting surface (1) and the second supporting surface (2); and the first supporting surface (1) and the second supporting surface (2) can be movably and detachably connected together through the connecting piece. Compared with the prior art, the suction disc has the advantages that: it is convention and reliable to mount the suction disc on an automobile sunshade curtain with the two movable and detachable supporting surfaces arranged above the suction part; it is only a small hole that is needed to form on the automobile sunshade curtain, which lowers the overall processing cost and makes it more suitable for the suction disc to be used on the automobile sunshade curtain; and supported by the two supporting surfaces, the curtain surface of the automobile sunshade curtain is smoother and is well attached onto the side surface of automobile glass.

Description

technical field [0001] The invention relates to a suction cup, in particular to a suction cup which can be used for automobile sunshades. Background technique [0002] Car sunshades are mostly positioned on the windshield or window of the car by suction cups. Just disclose a kind of sucker structure in " a kind of structurally improved car sunshade sucker " that Chinese patent announcement number is CN2495495Y, and this sucker is provided with two circular inserts that are arranged at intervals on the rear side of the sucking part. The circumferences of the two circular embedding pieces are all larger than the metal sheet holes fixed in the center of the sunshade curtain, and a pull-off strip is also connected on the side of the outer edge of the suction cup. When in use, because the two circular inserts of the suction cup are integrally designed with the suction part, they cannot be separated. Between the shaped block and the suction part, the actual operation is laboriou...
