Abstract

The utility model relates to an adjustable strong sucking disc which belongs to a daily life article and which is an improved vacuum suction type sucking disc; the utility model comprises a sucking disc body, an air-pumping pole, a suction cup and a nut. One end of the air-pumping rod is fixed on the sucking disc body, and the other end of the air-pimping rod is provided with screw threads; hanging holes are arranged on the nut. When the sucking disc presses on the smooth hard surface, the nut is screwed and the central part of the sucking disc body is raised gradually to make the sucking disc body produce vacuum adsorptive force to the hard surface and make the sucking disc body adsorb the hard surface tightly. The utility model which is adjustable has strong adsorptive force and is convenient for adding accessories to expand hanging range.

Description

Adjustable strong sucking disc

The utility model belongs to daily living article.

The structure of various vacuum adsorption type suckers that is used to hang clothing in the prior art is all undesirable, wherein a kind of sucker has the sucker of being made by elastomeric material, and the affixed air exhaust rod of an end of being made by rigid plastics and sucker, inverted bowl type housing, an end that the centre has through hole have cam configuration and the other end is hook-shaped extension object and be connected bearing pin etc. and form.It hangs the object root configurations is two square plates, the termination of air exhaust rod can be inserted hang the object root two square plates in the middle of, leave the hole, garden that the connecting pin axle is inserted on the plate, to hang object by a connection bearing pin and connect together, and the extension object is freely rotated on bearing pin with air exhaust rod.There is the cam configuration of a fritter projection side of the square plate of root, when rotating the extension object, cam configuration is slided along the inverted bowl type housing, thereby hold out against the inverted bowl type housing, make its periphery compress the periphery of sucker, the middle body of the sucker of having mentioned air exhaust rod simultaneously and having linked to each other with air exhaust rod makes sucker extract constant vacuum state out.But there is following shortcoming in the sucker of this structure: one, non-adjustable at the position angle of the crozier of hanging object one end; Two, it is inhomogeneous to hang the effect of holding out against of cam configuration make-up bowl sandwich type element of the object other end, thereby the compressing also inhomogeneous of periphery of sucker influenced vacuum; Three, it is long and be upper and lower switching formula to hang the bodily form of object, causes sucker to come off because of accident collision is disengaged vacuum easily.

The purpose of this utility model provides a kind of through improved adjustable powerful electromagnetic chuck.It has overcome the shortcoming of above-mentioned sucker, can conveniently adjust the diverse location and the angle of hook, can evenly compress the periphery of sucker, and is easy to operate, stable working state, safety, and absorption affinity is strong, and extension thing scope is wide.

The utility model is achieved in that it also has sucker, there is taking out glass (being called the inverted bowl type housing in the prior art) of through hole air exhaust rod that one end and sucker are affixed and the centre that can allow the air exhaust rod free end pass, be characterized in being provided with screw thread at the air exhaust rod free end, also have a nut that mates with the air exhaust rod screw thread, on nut, have a hanging hole at least near the place, outer.

Consider multiple factors such as economical with materials, attractive in appearance and practicality, different shape can be caused in the outside of nut.Just an end of hook is colluded in the hanging hole of nut when using this sucker.

The utlity model has following advantage: one, the principle that cooperates with screw rod with nut, thus it is also even to compressing of sucker periphery to make nut evenly take out cup to the pressure of taking out cup.Thereby can regulate the adsorption capacity of the height adjusting sucker of mentioning air exhaust rod simultaneously.Can also make sucker and be adsorbed vacuum is to greatest extent arranged between the face.Two, the turn nut just can be adjusted position, the angle of hanging hole.Three, on the nut if two or more hanging holes are arranged, be easier to hanging hole is gone to the position of suitable dress hook.Four, can utilize a plurality of hanging holes that the annex of a plurality of pins is installed, between two cover suckers and annex, adorn a pipe (or bar), thereby enlarge the extension thing scope of sucker.Five, need two fingers just make things convenient for rotating nut, even thereby be subjected to accident collision and also be not easy to be disengaged vacuum, duty safety, stablize.Six, adopt the mode of rotating nut, operate simple and easy, convenient.

Further illustrated below in conjunction with the accompanying drawing illustrated embodiment.

Fig. 1 is a half section front view of the present utility model;

Fig. 2 is a vertical view of the present utility model.

See Fig. 1,2, (for example: the center of top of the sucker of rubber) making 1 and the stub end of air exhaust rod 2 are affixed with elastomeric material, the other end of air exhaust rod (free end) is processed with screw thread, the centre has the cup 3 of taking out of through hole to cover on sucker 1, air exhaust rod 2 threaded free ends pass from taking out cup 3 middle through holes, nut 4 is sleeved on the air exhaust rod threaded end and screws in to the lower surface of nut 4 and contact with the upper surface (planar section) of taking out cup, continue screwing in nut 4 makes and takes out glass rim of a cup and evenly compress the sucker periphery, nut is mentioned the middle body of air exhaust rod 2 and sucker 1 simultaneously, and affect around it, the bottom surface of sucker forms a darker concave surface gradually like this.If sucker is to be pressed on the smooth bright and clean stiff dough, then screws nut gradually and will make sucker be enhanced to whole sucker gradually to be adsorbed on securely on this smooth bright and clean stiff dough at the vacuum adsorption force on this stiff dough.The hanging hole 5 that is provided with near the edge on nut is used to adorn hook or annex.

The vertical view of the nut outer shape of present embodiment is a cross, is evenly equipped with four hanging holes, sees Fig. 2, and the moving nut of revolution just has a hanging hole to be in suitable extreme lower position and the best angle of hanging thing (bearing gravity load) for 90 °.

If flatly be adsorbed on the wall with this sucker of the two covers segment distance of being separated by, annex of plug-in mounting in each nut, there are four pins the inboard of this annex in four hanging holes of nut, there is an annulus in the outside of annex, a pipe (or bar) is penetrated in the annulus of two annexes, just can utilize horizontal tube (or bar) to hang thing, the scope of hanging thing like this is so great that many.

Claims (1)

1, a kind of adjustable powerful electromagnetic chuck that is used to hang thing on the smooth bright and clean stiff dough that is adsorbed on as daily necessities, there are take out glass (3) of through hole the centre that has the affixed air exhaust rod (2) of sucker (1), an end and sucker (1) and can allow the air exhaust rod free end pass, it is characterized in that the air exhaust rod free end has screw thread, also have a nut (4) that mates with the air exhaust rod screw thread, on nut, have a hanging hole (5) at least near the place, outer.
