Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

Example 1

A suction cup hook applicable to a rough interface is shown in figure 1 and comprises a hook body 1 and a suction cup body 2. The sucker body 2 can be a conical vacuum sucker comprising an inner side surface of an outer side surface, the outer side surface is connected with the hook body 1, the inner side surface is tightly attached to the adsorption interface, air between the inner side surface and the adsorption interface is exhausted, and after vacuum is formed, the sucker body 2 can be adsorbed on the adsorption interface under the action of external atmospheric pressure. Because when adsorption interface is rough interface, the microstructure on rough interface is the concave-convex surface, make the air between 2 medial surfaces of sucking disc main part and the concave-convex surface difficult to arrange to the greatest extent, therefore, in this application, the medial surface is equipped with sponge layer 21, sponge layer 21 has porous soft effect, through the extrusion with sponge layer 21 and rough interface full contact, fill the gap of the concave-convex surface on rough interface, the leakproofness between sucking disc main part 2 and the rough interface has been improved, make and form vacuum state between sucking disc main part 2 and the rough interface, thereby improve adsorption effect.

Further, in this embodiment, the sponge layer 21 includes a fixed end connected to the inner side surface and a contact end contacting the rough interface, and the apertures of the sponge layer 21 are sequentially increased along the direction from the fixed end to the contact end. The sponge layer 21 close to the sucker main body 2 has high density and small aperture, and is beneficial to being contacted with the sucker main body 2; the sponge layer 21 contacting the rough interface has small density, large aperture and softness, and is beneficial to realizing the filling effect.

In order to improve the practicality of this application sucking disc couple, in this embodiment, sucking disc main part 2 can be dismantled with couple main part 1 and be connected. The detachable manner can be various, and in the embodiment, the suction cup main body 2 and the hook main body 1 are detachably connected through a thread structure. In more detail, the screw structure in the present embodiment includes an internal screw hole provided in the hook body 1 and a stud 22 provided on an outer side surface.

Because air needs to be discharged between the inner side surface of the sucker main body 2 and the rough interface, in order to improve the convenience of air discharge, in the embodiment, the hook main body 1 comprises a connecting body 11 provided with a through hole and an adjusting body 12 provided with an internal threaded hole, and the stud 22 penetrates through the through hole and then is connected with the internal threaded hole; one side of the connector 11 close to the sucker main body 2 is provided with a pressing part for pressing the sucker main body 2 to the rough interface, the pressing part is conical, and the conical degree of the pressing part is greater than that of the sucker main body 2 in a state of not being subjected to external force. The hook 13 may be provided on the connecting body 11. When the sucker main body 2 is used, the adjusting body 12 is rotated after the sucker main body 2 is tightly attached to a rough interface, the adjusting body 12 rotates and moves downwards on the stud 22, the connecting body 11 and the pressing part thereof are driven to compress the sucker main body 2, and therefore air between the sucker main body 2 and the rough interface is exhausted.

Example 2

This embodiment is basically the same as embodiment 1 except that the exhaust structure is different. In this embodiment, as shown in fig. 2, the stud 22 is a through hollow column, so that openings are respectively formed at two ends of the stud 22, the opening at one end of the stud 22 is disposed on the inner side surface, the opening at the other end of the stud 22 is connected with the exhaust member, and air between the inner side surface and the rough interface is extracted through the exhaust member.

The exhaust member may have various structures, in this embodiment, the exhaust member includes a piston 231 disposed in the stud 22 and a piston rod 232 connected to the piston 231, when in use, the piston rod 232 is pushed first to make the piston 231 close to the suction cup body 2, and after the suction cup body 2 is attached to the rough interface, the piston rod 232 is pulled to make the piston 231 far from the suction cup body 2. In addition, in order to fix the pulled position of the piston rod 232 and avoid the exhaust effect failure caused by the piston rod 232 moving under external force, the stud 22 is further provided with a stopping portion 221 for preventing the piston 231 from falling off from the stud 22, and the piston 231 and the stopping portion 221 can be connected in a magnetic attraction manner.

The specific embodiments described herein are merely illustrative of the spirit of the utility model. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the utility model as defined in the appended claims.
