Description

Vacuum chuck

Technical field

The invention belongs to haberdashery and hardware, especially a kind of sucker that is used to support object on the smooth metope that is installed in.

Background technique

The common knob style vacuum chuck in market makes it to cause vacuum through the slope pull-up sucker sheet middle part in the rotation rotating disk and can adsorb for a long time on the wall, and installing and using of it is very convenient, can not destroy wall again.But there are two deficiencys in existing product: at first; Mostly the hook of this vacuum chuck is that round bar bends and forms; The round bar head is directly filled in the circular hole at sucker sheet center, because the frictional force between round bar head and the circular hole is limited, so hook is always hanging up the object post deflection downwards; Like this, just can not adapt to other usage mode that keep flat hook or make progress; Secondly, the part that climbs in the vacuum chuck just rests on flat segments behind the top, slope of climbing, do not pin function in this stop place, retreats easily when the rotating disk of sucker receives the little grazing of foreign object, has removed vacuum, and sucker is come off from wall.

Summary of the invention

In order to overcome the shortcoming of existing product, the present invention provides a kind of vacuum chuck, and its hook can keep the installment state to any direction securely, and can not removed stage makeup and costume easily after installing.

The present invention includes shell, undersetting, torsion spring and the sucker of box-like; Enclosure has the slideway of being with the slope more than two along the housing circumference, and there is through hole at the shell center; Undersetting has a plurality of plunger holes and two with convex platform in the form of a ring on it; There is an attachment post at the sucker center, and there is a block on the attachment post next door, and the sucker periphery has a plurality of plungers, and attachment post passes the through hole of shell, and plunger embeds the plunger hole of undersetting; Two of torsion spring respectively with block and housing contacts; It is characterized in that place kick is arranged on the boss, boss contacts with slideway through place kick, and the location shrinkage pool is arranged on the slideway, and the location shrinkage pool is positioned at place kick on the mobile route on the slideway; The collar groove is arranged on the attachment post, and the collar groove is positioned at the position that attachment post stretches out through hole, has a collar to be stuck on the collar groove; The cross section of attachment post is a polygonal; The end of attachment post is equipped with a hook, and an end of hook has the cross section with the identical shaped counterbore in attachment post cross section, and the counterbore of hook is enclosed within on the attachment post end.

As a kind of preferred structure of the present invention, boss has open caisson and spring, and the location ball and spring is installed in the open caisson.

As another kind of preferred structure of the present invention, place kick is fixed on the boss.

As to further improvement of the present invention, the cross section of attachment post is a square; Screw is arranged on the hook, and screw and counterbore connect, and Cock screw is arranged in the screw.

The present invention is nested with the polygonal counterbore being improved to sucker sheet and being connected of hook polygon shaft, makes hook can not increase the slideway self-locking structure in addition because of hanging thing deflection, has strengthened the reliability of sucker absorption.The present invention is monoenergetic suspension weight not, can also lift weight or lifts up.It suits to install and use in occasions such as family, office, market and hotels.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.

Referring to Fig. 1 to Fig. 3, shell 1 usefulness metal or plastics are processed, and shell 1 is box-like, and shell 1 center is provided with a retraction cylindraceous portion 25, and a through hole 6 is arranged on it; There are three slideways 5 shell 1 inside along the housing circumference, and every slideway 5 is formed by one section flat segments and one section slope smooth connection; A hemispheric location shrinkage pool 13 is all arranged on every slideway 5.

Undersetting 2 usefulness metals or plastics are processed, and undersetting 2 is evenly distributed with 16 plunger holes 7, three boss 8 and three second boss 22 in the form of a ring on it; Each boss 8 all has an open caisson 19 and a spring 18, and place kick 12 is steel balls, and steel ball and spring 18 are installed in the open caisson 19, and place kick 12 can fall into the location shrinkage pool 13 on the slideway 5 when on slideway 5, moving.Feel when steel ball and spring being set making rotation case is good especially.

An attachment post 9 is extended at sucker 4 centers, and this attachment post is to make with metal, and its afterbody is fixed on the sucker center of flexible silicone rubber system.The cross section of attachment post 9 is square, is shaped on a crack 27 on it on it; There is the block 10 of a rectangle on attachment post 9 next doors; Flexible sucker body 4 peripheries have eight plungers 11.Eight plungers 11 embed eight among 16 plunger holes 7 of undersetting 2 respectively; Attachment post 9 passes the through hole 6 of shell 1, and a collar groove 14 is arranged on the attachment post 9, and collar groove 14 is positioned at the position that attachment post 9 stretches out through hole 6, has a collar 15 to be stuck on the collar groove 14.

Two of torsion spring 3 props up the draw-in groove 24 in block 10 and the retraction portion 25 respectively, and the elastic force of torsion spring 3 always tries hard to make place kick 12 to fall along the slope like this.

Referring to Fig. 4, place kick when shell 1 moves right on undersetting 2 boss 8 12 moves to flat segments from the slope, is pressed into location shrinkage pool 13 by spring 18 then, and at this moment the distance of 2 of shell 1 and undersettings is bigger, and flexible sucker body center portion is pulled up.Because shell 1 is locked with undersetting 2, shell 1 can not move to left easily.Second boss 22 of undersetting 2 is a usefulness of making shell 1 rotary spacing with the baffle plate 23 of shell 1 among the figure.

Referring to Fig. 5, firmly twist shell 1 and be moved to the left, force place kick 12 on undersetting 2 boss 8 to leave location shrinkage pool 13, move to the bottom, slope from flat segments, at this moment the distance of 2 of shell 1 and undersettings is less, and flexible sucker body center portion is put down.

Referring to Fig. 6 and Fig. 7, at the attachment post end of sucker a hook 16 is installed, an end of hook 16 has with the identical shaped square counterbore 17 in attachment post 9 cross sections, and the counterbore 17 of hook 16 is enclosed within on attachment post 9 ends.Screw 20 is arranged on the hook 16, and screw 20 connects with counterbore 17, and screw is rotary with Cock screw 21 for 20 li, and screw is shot the crack of attachment post when being connected with hook.

Referring to Fig. 8, embodiment 2 is at first that with embodiment 1 difference a protruding ball 12 in hemispheric location is all extended on the plane from each boss 8, and boss 8 contacts with the slideway of shell through the protruding ball 12 in location, like this can simplified structure.Next is that the attachment post 9 at embodiment 2 sucker center is that ABS or PC plastics are processed, and it is injection-moulded in the sucker center of making of silicone rubber, and the crack is not set on it, and the screw roof pressure is on the surface of attachment post when being connected with hook; And the block 10 that is connected on the sucker is columniform.

Above-mentioned two examples of implementation are not exclusive mode of execution of the present invention, and in other mode of execution, the cross section of attachment post 9 can be any polygonal shape, such as rectangular, pentagon, Hexagon or the like; Retraction portion 25 on the shell 1 also can cancel, and through hole 6 is just opened on plane on the shell 1; The profile of hook also can be made various variation.Showed among Fig. 9 that by two vacuum chucks of the present invention and the towel rack that cross bar constitutes, among the figure, cross bar 26 is hooks of a double end.
