Problems solved by technology
[0002] Suction cups are widely used because they are easy to use, glued, and do not need to drill walls. However, the suction force of existing suction cups is not strong enough, and they are easy to fall off. Therefore, the structure of existing suction cups needs to be improved.
Existing suction cups are usually provided with elastic colloid, and a convex ring is arranged on the elastic colloid. Since the convex ring is made of soft rubber, there is no supporting frame in the convex ring, and it will be deformed when pressed, and the force will be uneven, so it cannot be used well. It plays the role of transmitting contact pressure, and the suction cup is easy to fall off

Embodiment Construction
[0011] The present invention will be described in detail below with reference to the accompanying drawings: a suction cup includes a skeleton 1, a connecting rod 11 and an annular rib 12 are arranged on the back of the skeleton 1, and the skeleton 1 is covered with an elastic colloid 2 , the elastic colloid 2 covers the convex rib 12 to form a convex ring 21, the connecting rod 11 is sleeved with a suction cup cover 3, and the back of the suction cup cover 3 is connected with the connecting rod 11 and pulled The pressing frame 1 realizes the connecting and fixed connecting piece 5 , and the protruding ribs 12 are pressed against the bottom surface of the suction cup cover 3 . Since the convex rib 12 is pressed against the bottom surface of the suction cup cover 3, the convex rib 12 can transmit the contact pressure well when pressing, so that the suction cup is not easy to fall off.
[0012] The protruding ribs 12 are composed of discontinuous annular protrusions.

The invention relates to a sucking disc which comprises a skeleton. A connecting rod and a ring-shaped protruding rib are arranged on the back of the skeleton. The skeleton is coated with an elastic colloid. The position, wherein the protruding rib is located, of the elastic colloid is coated to form a protruding ring. The connecting rod is provided with a sucking disc cover in a sleeved manner. The back of the sucking disc cover is connected with a connecting piece, the connecting piece is connected with the connecting rod and pulls and presses the skeleton to achieve connection and fixation.The protruding rib abuts against the bottom face of the sucking disc cover. The sucking disc aims to overcome the defects in the prior art, the protruding rib is arranged in the protruding ring and can be effectively protected by the protruding ring, thus, contact pressure can be effectively transferred, and the sucking disc does not fall off easily.
Description
technical field [0001] The present invention relates to a suction cup. Background technique [0002] Suction cups are widely used because they are easy to use, glued during use, and do not require drilling walls. However, the suction force of the existing suction cups is not strong enough, and it is easy to fall off. The structure of the existing suction cups needs to be improved. The existing suction cups are usually provided with an elastic colloid, and a convex ring is arranged on the elastic colloid. Since the convex ring is made of soft rubber, there is no supporting frame in the convex ring, and it will deform when pressed, and the force will be uneven, which cannot be very good. It plays the role of transmitting the contact pressure, and the suction cup is easy to fall off. [0003] The present invention has been made based on this situation. SUMMARY OF THE INVENTION [0004] The invention overcomes the deficiencies of the prior art and provides a suction cup whic...
