Description

Sucker base and sucker using same

Technical Field

The utility model relates to a sucking disc field especially relates to a sucking disc base and use sucking disc of this sucking disc base.

Background

The sucking disc couple is comparatively conventional articles for daily use, common couple covers on other planes such as wall body through double faced adhesive tape, the couple of this kind of formula of gluing is higher to the roughness and the smooth finish requirement on attachment surface, and can only the bearing article that are lighter, aggravate slightly and will have the risk that drops, and blow with illumination through a period of time, make the double faced adhesive tape inefficacy very easily, furthermore, the traditional couple of double faced adhesive tape formula, take off inconveniently after the use, and can leave obvious offset printing on the attachment after taking off, influence pleasing to the eye.

Then, a sucker type hook appears on the market, a common sucker type hook still has certain requirements on the surface flatness and the smoothness of an attachment body, the sucker type hook is pushed and pressed by hand push or a related tool to enable air in a sucker to be discharged to form negative pressure so as to be adsorbed on the attachment body, the sucker type hook overcomes the defects that the traditional double-faced adhesive tape type hook is inconvenient to take off and not attractive, the sucker can be taken off as long as a negative pressure area of the sucker is communicated with an external part, the sucker is very convenient and does not leave any trace, for example, the prior application of the applicant, Chinese utility model application No. CN201620730278.9, namely a fixing structure of a sucker, the fixing structure is provided with a through hole on a sucker seat, the sucker is arranged at the rear side of the sucker seat, the sucker is provided with a threaded connecting column in a forward protruding manner, the threaded connecting column passes through the through hole and the through hole can prevent the threaded connecting column from rotating relatively, and the threaded locking part and a connecting sleeve are arranged at the front side of the sucker seat, the threaded locking part is in threaded connection with the threaded connecting column, and the threaded locking part is installed in the connecting sleeve and can synchronously rotate with the connecting sleeve. This sucking disc fixed knot constructs's sucking disc is spacing on the sucking disc seat, and screw thread retaining member threaded connection is on the threaded connection post of sucking disc, and the adapter sleeve is connected fixedly with screw thread retaining member, and fixed knot constructs very simply, during the installation, only need install the screw thread retaining member earlier on the adapter sleeve, then rotate screw thread retaining member and adapter sleeve and just can extrude the air at the sucking disc back to fix the sucking disc on the wall, it is very convenient to install, and the installation back sucking disc is difficult for droing from the wall.

Above-mentioned sucking disc has good adsorption effect when using, but because during the interior inserts knob, can outwards pull the center department of sucking disc, because the sucking disc surfacing, it can make the wallboard of annular groove both sides inhomogeneous to compressing tightly on sucking disc surface to pull the back, and this will lead to the sucking disc atress inequality, has increased the risk that the sucking disc drops.

Also, as in the chinese practical patent of chinese patent No. cn201620870251.x, the suction cup is provided with an inner concave skeleton 3 on the surface of the cup body to further enhance the adsorption effect, but it is still not ideal.

There is therefore a need for further improvements in suction cup hooks.
