Abstract

The utility model relates to a suction cup controlled by cam, which comprises a disc-shaped suction cup body, wherein the top portion of the suction cup body is a plane and is provided with a through hole, a disc hole of the suction cup body is provided with a flexible suction cup pad which covers the disc hole of the suction cup pad, a suction cup handle which is fixed on the center of the suction cup pad is threaded out from the through hole and is in clearance fit with the through hole, a compression spring is sleeved on the suction cup handle, and is arranged between the suction cup pad and the suction cup body, a cam is hinged on the suction cup handle through a pin shaft, and a handle is arranged on the cam. When the suction cup is absorbed and fixed on the smooth plane of an object, the adsorptive force is greatly reinforced, and the suction cup can be firmly absorbed and fixed on the smooth plane of an object without moving, and the suction cup can not drop from the smooth plane of an object.

Description

Sucker with cam control

Technical field

The utility model relates to a kind of sucker that is used for fixing object, particularly the sucker of controlling with cam.

Background technique

Sucker is a kind of fixing device of object, object attached to it can be fixed on the smooth flat of other object, on the surface as glass, ceramic tile, wood furniture etc.The main body of sucker is discoid sucker, and sucker is generally made by flexible plastic, can produce distortion.When on the smooth flat that firmly sucker is pressed in object, sucker produces distortion and the air in the sucker dish chamber is discharged, after the external force disappearance that acts on the sucker, sucker will restore to the original state as far as possible, and make sucker dish chamber form vacuum state, so sucker is absorbed and fixed on the smooth flat of object.But, when existing sucker produces distortion at sucker, air in the sucker dish chamber can not all be discharged, after sucker restores to the original state as far as possible, degree of vacuum in the sucker dish chamber is not too high, thereby makes the fixing dynamics of the absorption of sucker not enough, so after on the smooth flat that object is fixed on other object with sucker, sucker will produce displacement after a while, even come off from the smooth flat of object.

The model utility content

The purpose of this utility model provides a kind of sucker with cam control, adsorbs fixing dynamics to increase sucker on the object smooth flat.

Sucker with cam control described in the utility model, comprise discoid sucker, the sucker top is the plane and offers through hole, the Pan Kou place of sucker is provided with soft sucker pad sucker body disc mouth is covered, the sucker pad center fixation has the sucker handle, the sucker handle passes from described through hole and cooperates with this via clearance, be set with pressure spring on the sucker handle, it is between sucker pad and sucker, be hinged with cam by bearing pin on the sucker handle, cam is provided with handle, under the pressure spring effect, the contoured surface of cam contacts with the sucker top plan, when the cam profile face of distance bearing pin farthest contacts with the sucker top plan, described handle just in time contacts with sucker, and sucker pad produces depressed deformation in the sucker inner chamber simultaneously.

During use, after the smooth flat applying with sucker pad in this sucker and object, pull the handle on the cam, making cam overcome pressure spring power rotates around bearing pin, when the cam profile face of bearing pin farthest contacts with the sucker top plan (because the handle on the cam contacts with sucker, stopped by sucker and cam can not be rotated further), sucker just is absorbed and fixed on the smooth flat of object securely to the cam, when needs take off sucker, the handle on the cam turned back get final product.

At the above-mentioned cam handle of pulling, sucker is adsorbed in the process on the smooth flat of object, on the one hand, cam applies a downward pressure to sucker, makes sucker body disc mouth sucker pad is pressed on the smooth flat of object; On the other hand, the sucker handle that is fixed on the sucker pad moves outside cam and bearing pin drive sucker arbor alignment sucker top, lower edge, thereby the pulling sucker pad moves to the sucker inner chamber, makes sucker pad produce depressed deformation in the sucker inner chamber.Because the formed cavity of sucker pad depressed deformation is in vacuum state completely, its degree of vacuum is very high, so sucker can be absorbed and fixed on the smooth flat of object securely.And when the handle on the cam is turned back, under the pressure spring effect, cam will rotate back into original location status, simultaneously, sucker body disc mouth disappears to the pressure of sucker pad, and sucker pad returns to original plane shape, and the formed vacuum cavity of sucker pad disappears, make sucker lose adsorption force, so can easily this sucker be taken off from the smooth flat of object to the smooth flat of object.

The utility model is owing to have this kind structure, when it is absorbed and fixed on the smooth flat of object, its adsorption force is able to great enhancing, so this sucker with cam control can be absorbed and fixed on the smooth flat of object securely, and can not produce displacement, more can not come off from the smooth flat of object.

Description of drawings

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is the main pseudosection of the sucker with cam control described in the utility model;

Fig. 2 is the plan view of Fig. 1;

Fig. 3 is absorbed and fixed at the phase diagram on the smooth flat of object for this sucker with cam control.

Embodiment

As depicted in figs. 1 and 2, this sucker with cam control comprises the discoid sucker made from duroplasts 6, sucker 6 tops are plane 5 and offer through hole, and the Pan Kou place of sucker 6 is provided with the soft sucker pad of being made by plastic cement 7, and this sucker pad 7 covers sucker 6 Pan Kou.Sucker pad 7 center fixation have sucker handle 8, and sucker handle 8 passes from described through hole and cooperates with this via clearance, is set with pressure spring 1 on the sucker handle 8, and it is between sucker pad 7 and sucker 6.Be hinged with cam 2 by bearing pin 4 on the sucker handle 8, cam 2 is provided with handle 3 and combines as a whole with cam 2, under pressure spring 1 effect, the contoured surface of cam 2 contacts with sucker 6 top plan 5, when cam 2 contoured surfaces of distance bearing pin 4 farthest contact with sucker 6 top plan 5, described handle 3 just in time contacts with sucker 6, and sucker pad 7 produces depressed deformation in sucker 6 inner chambers simultaneously.

As shown in Figure 3, after this smooth flat applying with sucker pad in the sucker of cam control 7 and object 9, the handle of pulling on the cam 23 rotates cam 2, to the cam 2 when cam 2 contoured surfaces of bearing pin 4 farthest contact with sucker 6 top plan 5, sucker pad 7 produces depressed deformation in sucker 6 inner chambers, sucker just is absorbed and fixed on the smooth flat of object 9 securely.

Claims

1, a kind of sucker with cam control, comprise discoid sucker (6), it is characterized in that: the sucker top is plane (5) and offers through hole, the Pan Kou place of sucker is provided with soft sucker pad (7) sucker body disc mouth is covered, the sucker pad center fixation has sucker handle (8), the sucker handle passes from described through hole and cooperates with this via clearance, be set with pressure spring (1) on the sucker handle, it is between sucker pad and sucker, be hinged with cam (2) by bearing pin (4) on the sucker handle, cam is provided with handle (3), under the pressure spring effect, the contoured surface of cam contacts with the sucker top plan, when the cam profile face of distance bearing pin farthest contacts with the sucker top plan, described handle just in time contacts with sucker, and sucker pad produces depressed deformation in the sucker inner chamber simultaneously.
