Description
Technical field
The utility model relates to a kind of sucker that can be adsorbed in plane.
Background technique
In daily life, work; for hanging articles; sucker often can be used to provide suspension strut power; the working method of sucker is generally discharged by the air in disk body by extruding disk body; make to form negative pressure between disk body and adsorbing plane, thus reach sucker and directly adsorb in the plane to provide the object of suspension strut power.
Although existing sucker can be adsorbed in plane and provide suspension strut power, but along with the passing of service time, disk body can recover deformation gradually, outside air slowly enters disk body, negative pressure value between disk body and adsorbing plane is more and more less, the suspension strut power that sucker can be provided is more and more less, and sucker will come off from absorption surface in the near future, cannot continue to provide suspension strut power.
When hung object is heavier, more can impel disk body generation deformation, outside air just enters disk body sooner, causes sucker to come off from absorption surface soon.
In addition, the suspension strut power that existing sucker provides is produced by the negative pressure formed between disk body and adsorbing plane completely, and the size of suspension strut power depends on the size of negative pressure value completely.The negative pressure that can be formed due to existing sucker is produced by the mode of extruding disk body, so the negative pressure value that can reach between disk body and adsorbing plane is limited, the suspension strut power that sucker can provide is limited.
Summary of the invention
The technical problems to be solved in the utility model is to provide the sucker that a kind of adsorption time is long, suspension strut power is large.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: sucker, comprises adsorbable in the disk body of plane, also comprises:
Pressure drag part, this pressure drag part can be pressed on the periphery of described disk body, forms closed annular face contacts with described disk body;
Lifting piece, the central part of this lifting piece and described disk body is affixed, can lift the central part of described disk body;
Inspire part, this inspires the top that part is positioned at described pressure drag part, is flexibly connected by screw thread with described lifting piece; This inspires part and described pressure drag part can be impelled to be pressed on the periphery of described disk body, and the central part of described lifting piece to described disk body can be impelled to lift.
Working method of the present utility model is: first, the same with existing sucker, makes disk body be adsorbed in plane, form preliminary absorption by extruding disk body; Then, inspire part by rotating, make to inspire part threadingly relatively lifting piece move downward, the pressure drag part below it is impelled to be pressed on the periphery of disk body downwards, make pressure drag part and disk body form closed annular face contacts, thus make outside air be difficult to enter disk body, reach the object extending adsorption time; After pressure drag part and disk body are formed and contact, inspiring part by continuing rotation, lifting piece can be made relatively to inspire part and move upward, thus the central part of disk body is upwards lifted, make disk body inside form larger negative pressure, reach the object increasing suspension strut power.
Part is inspired, when pressing down pressure drag part in rotation, for ensureing that pressure drag part is just pressed on disk body downwards, pressure drag part can not rotate by the effect inspiring part, to ensure that pressure drag part is pressed on disk body, stops the effect that outside air enters, described disk body is provided with the anti-rotation cylinder of protrusion, described pressure drag part is provided with the anti-rotating hole suitable with described anti-rotation cylinder, and described anti-rotation cylinder puts in described anti-rotating hole.
Further, for pressing partially when ensureing that pressure drag part presses down, the quantity of described anti-rotation cylinder is at least two, and the quantity of described anti-rotating hole is no less than the quantity of described anti-rotation cylinder.
Further again, the anti-rotation cylinder of described at least two is evenly arranged along the periphery of described disk body, and the position of described anti-rotating hole is corresponding with the position of described anti-rotation cylinder.
For reduce pressure drag part press down touch disk body time, shorten the rotating distance inspiring part, described pressure drag part is provided with at least two and presses down inclined-plane, and the inclined-plane that presses down of described at least two is uniformly distributed around the described rotating center inspiring part; Described inspire part be provided with can be pressed on described in press down briquetting on inclined-plane.
Further, for restriction inspires the rotating distance of part, described in press down inclined-plane high end be provided with the draw-in groove with described briquetting adaptation.
Further again, during for ease of inspiring part revolution, briquetting exits from draw-in groove, and the exit surface of described draw-in groove is cambered surface.
Inspire that part makes that pressure drag part is pressed on the periphery of disk body downwards, after lifting piece upwards lifts the central part of disk body rotating, turn round for obstruction inspires part, further guarantee pressure drag part is pressed on disk body, the described part that inspires is provided with the rod member protruded downwards, described pressure drag part is provided with elasticity barrier member, described elasticity barrier member is arranged on the rotate path of described rod member, the end of described elasticity barrier member is provided with and can hinders the pivotal obstruction face of described rod member, and described rod member arrives described obstruction face with the described side slip inspired along described elasticity barrier member when part rotates.When described rod member with described inspire part rotate time, described elasticity barrier member is by the effect generation deformation of described rod member, when described rod member inspires after part is rotated in place with described, described rod member is just in time resisted against on the obstruction face of described elasticity barrier member end setting, and described elasticity barrier member recovers deformation and also utilizes its obstruction face to turn round by inspiring part described in described rod member obstruction.
Further, inspire part for increasing obstruction pivotal effect occurs, described rod member and the quantity of described elasticity barrier member are corresponding multiple.
Further again, for hysteresis inspires part, pivotal obstruction power occurs, described multiple rod member is uniformly distributed around the described rotating center inspiring part accordingly with described multiple elasticity barrier member.
The utility model is novel in design, and structure is ingenious, utilizes pressure drag part to be pressed on the periphery of disk body downwards, forms the annular face contacts closed, makes outside air be difficult to enter disk body, thus has the long feature of adsorption time; Utilize again lifting piece upwards to lift the central part of disk body simultaneously, make the inner negative pressure that formation is larger further of disk body, thus there is the large feature of suspension strut power.
