Description

A kind of vacuum tightness sucker

Technical field

The utility model belongs to the daily living article field, particularly a kind of vacuum tightness sucker.

Background technique

Vacuum chuck is widely used in various fields in life because its making is simple, with low cost and easy to use.Present common a kind of vacuum chuck, mainly form by sucker lid, sucker, handgrip and top cover, during use sucker and metope are fitted, turn handgrip then, handgrip drives sucker with respect to the up motion of sucker lid, because it is big that the volume of sucker faying surface becomes, and produces negative pressure of vacuum, thereby fit together with metope.

This vacuum seal sucker also exists adsorption force strong inadequately, the defective that comes off easily when hanging weight.

The model utility content

The purpose of this utility model provides a kind of adsorption force and strengthens, do not allow caducous vacuum tightness sucker.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of vacuum tightness sucker, comprise the sucker lid, be inserted in fixing rod and the sucker that is connected the fixing rod bottom in the sucker lid, between sucker lid and the sucker spring that is sheathed on the fixing rod is arranged, fixing rod also is provided with handgrip outward, the fixing rod tip portion is fixed with connecting rod, handgrip is provided with and holds the wedge groove that connecting rod wears, the sucker tops is provided with the coupling shaft that is inserted in the handgrip and flexibly connects with connecting rod, coupling shaft is provided with top cover outward, top cover is fastenedly connected by self tapping screw and coupling shaft, the top cover top is provided with the plug of encapsulation self tapping screw, is provided with the flexible glue pad between described sucker and the sucker lid.

Wherein, described sucker lid bottom end and flexible glue pad top end are provided with many interlaced anti-skidding raised lines.

Wherein, described sucker lid bottom end is evenly distributed around the center of circle a plurality of salient points, and flexible glue pad top end is provided with and the salient point corresponding groove.

In addition, described sucker, flexible glue pad and sucker lid are for circular, oval or square.Also be pivoted with the metal hanger on the described top cover.

The beneficial effects of the utility model are: be provided with the flexible glue pad between sucker and the sucker lid, flexible glue pad and sucker lid is pulled together when the turn handgrip, has improved seal greatly, makes the adsorption force of sucker strengthen greatly, is not easy to come off when hanging weight.
