Description

Vacuum cup

Technical field

The utility model 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 technology

The common knob vacuum cup in market makes it to cause vacuum by 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 weak points in existing product: at first, mostly the suspension member of this vacuum cup 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 suspension member is always hanging up the object post deflection downwards, like this, just can not adapt to other occupation modes that suspension member is kept flat or makes progress; Secondly, the part that climbs in the vacuum cup just rests on flat segments behind the top, slope of climbing, do not pin function in this stop place, and the rotating disk of sucker retreats when being subjected to the little grazing of foreign object easily, has removed vacuum, and sucker is come off from wall.

The utility model content

In order to overcome the shortcoming of existing product, the utility model provides a kind of vacuum cup, and its suspension member can keep the installment state to any direction securely, and can not removed stage makeup and costume easily after installing.

The utility model comprises shell, undersetting, torsion spring and the flexible sucker body 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 in the form of a ring with convex platform on it; There is a joint pin at flexible sucker body center, and there is a block on the joint pin next door, and flexible sucker body periphery has a plurality of plungers, and joint pin 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 having on the boss the protruding ball in location, boss contacts with described slideway by the protruding ball in location, and the location shrinkage pool is arranged on the slideway, and the location shrinkage pool is positioned at the protruding ball in location on the mobile route on the slideway;

The collar groove is arranged on the joint pin, and the collar groove is positioned at the position that joint pin stretches out through hole, has a collar to be stuck on the collar groove;

The cross section of joint pin is a polygon, and the end of joint pin is equipped with a suspension member; One end of suspension member has the cross section with the identical shaped counterbore in joint pin cross section, the via hole that penetrates into counterbore is arranged on the suspension member, the joint pin end has along the screw-threaded counterbore of joint pin axis direction, the counterbore of suspension member is enclosed within on the joint pin end, has a holding screw to pass via hole screw-in screw-threaded counterbore suspension member is pressed on the joint pin end face.

As further improvement of the utility model, the cross section of joint pin is a square.

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

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Referring to Fig. 1 to Fig. 3, shell 1 and the undersetting 2 of embodiment 1 are made of plastic, and flexible sucker body 4 usefulness silicon rubber are made.

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 is evenly distributed with 16 plunger holes 7, three boss 8 and three second boss in the form of a ring on it; Each boss 8 all has an open caisson 19 and a spring 18, and locating protruding ball 12 is steel balls, and steel ball and spring 18 are installed in the open caisson 19.Feel when steel ball and spring being set making rotation case is good especially.

A joint pin 9 is extended at flexible sucker body 4 centers, and the cross section of joint pin 9 is square; The joint pin end has the screw-threaded counterbore 26 along the joint pin axis direction, and there is a block 10 on joint pin 9 next doors; Flexible sucker body 4 peripheries have eight plungers 11.Eight plungers 11 embed eight in 16 plunger holes 7 of undersetting 2 respectively; Joint pin 9 passes the through hole 6 of shell 1, and a collar groove 14 is arranged on the joint pin 9, and collar groove 14 is positioned at the position that joint pin 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 crack 24 in block 10 and the retraction portion 25 respectively, and the elastic force of torsion spring 3 always tries hard to make the protruding ball in location 12 to fall along the slope like this.

Referring to Fig. 4, the protruding ball in location when shell 1 moves right on undersetting 2 boss 8 12 moves to flat segments from the slope, falls into location shrinkage pool 13 then, and at this moment the distance of 2 of shell 1 and undersettings is bigger, flexible sucker body centre is pulled up, and flexible sucker body and between the walls form vacuum.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 twisting shell 1 is moved to the left, force the protruding ball 12 in location 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, flexible sucker body centre is put down, and flexible sucker body and between the walls are removed vacuum.

Referring to Fig. 6, embodiment 2 is to extend on each boss 8 a protruding ball 12 in hemispheric location with the difference of embodiment 1, boss 8 contacts with the slideway 5 of shell 1 by the protruding ball 12 in location, locatees protruding ball 12 and can fall into location shrinkage pool 13 on the slideway 5 when mobile on slideway 5.

Referring to Fig. 7, at joint pin 9 ends of vacuum cup a suspension member 16 is installed, an end of suspension member 16 has with the identical shaped counterbore 17 in joint pin 9 cross sections, and the via hole 27 that penetrates into counterbore 17 is arranged on the suspension member 16; The counterbore 17 of suspension member 16 is enclosed within on joint pin 9 ends, and the screw-threaded counterbore 26 of passing on the via hole 27 screw-in joint pins 9 with a holding screw 21 is pressed on suspension member 16 on the end face of joint pin 9.

Above-mentioned two examples of implementation are not got rid of other embodiment, and in other embodiment, the cross section of joint pin 9 can be any polygonal shape, such as rectangle, pentagon, hexagon, octagon 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 suspension member also can be made various variation.

Showed among Fig. 8 by the common Hanging Basket that hangs of two vacuum cups of the present utility model.
