Description

TECHNICAL FIELD

[0001] The utility model relates to a sucking disc and belongs to daily necessities. BACKGROUND

[0002] In daily life, if an article needs to be hung on the wall (such as a photo, a towel, a hanging ornament, etc.), the traditional way is usually to knock a nail into the wall, and hang the article on the nail. The nail will punch a hole in the wall surface, affecting the appearance, and for some thin wall surfaces (such as a wood board with a thickness of only 5 mm), the nail cannot reliably fix the article. Therefore, on a smooth and flat wall surface, people usually use a sucking disc to adsorb and connect a hook on the outer wall of the sucking disc to hang the article on the hook. The existing sucking disc usually comprises a sucking disc body made of soft silica gel material, an adsorption cavity is formed on one side of the sucking disc body, and a hook is connected to the other side of the sucking disc body. This structure is very simple, but it has the following shortcomings: 1. The sucking disc body has no structure to press it tightly, resulting in poor adsorption capacity, and air is easy to enter the adsorption cavity, causing the sucking disc to fall off, so the sucking disc cannot hang a heavy article; 2. The hook is arranged on the back of the sucking disc, and can only hang some articles with corresponding structures (such as a hanging rope and a steel wire), so the function is single. SUMMARY

[0003] The utility model aims at overcoming the shortcomings of the prior art and providing a sucking disc with reliable adsorption, good load-bearing capacity and convenient article hanging.

[0004] The technical scheme of the sucking disc of the utility model is as follows: a sucking disc body, a support frame, a pressing disc and a connecting frame are provided, an adsorption cavity is formed on the lower part of the sucking disc body, the upper part of the sucking disc body is fixedly connected with the support frame, the pressing disc is arranged on the support frame, the connecting frame is arranged on the pressing disc, a fixed column is arranged on the middle part of the support frame, the head of the fixed column penetrates through the pressing disc and the connecting frame, the fixed column is fixed with the connecting frame through a fastener, one side of the connecting frame is provided with a connecting column, a front connecting plate and a rear connecting plate are arranged in the connecting column, a plug-in interface is formed between the front and rear connecting plates, a clamping groove is formed in the front connecting plate and communicates with the plug-in interface.

[0005] Further, a support skeleton is arranged around the support frame, the support skeleton is embedded in the sucking disc body, and a protruding support rib is arranged on the support skeleton.

[0006] Further, a tab is arranged on one side of the lower part of the connecting column close to the sucking disc body.

[0007] Further, a recess is formed in the connecting frame, a clamping hole is formed in the inner wall of the recess, a cover plate is arranged in the recess, barbs are arranged around the cover plate, and the cover plate is matched with the clamping hole in the inner wall of the recess through the barbs.

[0008] The beneficial effects of the utility model are: 1. During manufacturing, the support frame is put into the mold as an insert and integrally injection molded with the suction disc body. When the suction disc body is adsorbed on the wall surface, the pressing ring of the pressing disc is used to press the support rib of the support frame, the support frame is pressed to the suction disc body, so that the suction disc body can be adsorbed on the wall surface, the adsorption is reliable, and the bearing capacity is good; 2. The clamping groove is formed in the front connecting plate, the protruding insert piece can be arranged on the hook or the article to be hung, the insert piece is inserted into the plug-in interface, the plug-in connection is convenient, different types and sizes of hooks can be replaced, different requirements can be met, and the article is hung more conveniently.
