Description

But adhesive, the sucker of having taken off

The utility model belongs to a kind of parts of can adhesive on bright and clean plane, having taken off, but the sucker that is specifically related to a kind of adhesive, has taken off.

Existing adhesive dish, majority is the plastic disk of a softness, during use, presses down the plastic disk that adhesive is used, and the air in the dish from coiling interior eliminating, is caused vacuum in the dish, and dish is pull-in on the bright and clean surface tightly.This sucker need be taken off time-out, needs the edge with hand starting adhesive dish, and air enters in the dish, and the adhesive dish comes off voluntarily.Obviously, the method for this adhesive owing to do not have to solve the problem of having taken off, only is suitable for hanging small article in the daily life, and Applicable scope is smaller.

The purpose of this utility model is the sucker that but a kind of energy adhesive is provided, taken off.

But adhesive of the present utility model, the sucker of having taken off, it is characterized in that having the sliding sleeve of key in the central hole of an inverted bowl type support affixed, the other end of sliding sleeve affixed one has the position-limited rack of limited ring, between limited ring and sliding sleeve end, establish a nut, the free end that is threaded with the T of the falling ＂＂ character-shaped pull bar of keyway that is fixed in sucker upper end passes sliding sleeve from the opening end of support, nut and limited ring are arranged on sucker in the inverted bowl type support, the affixed end cap on the top of pull bar, edge at sucker joins by at least one rope and support upper inside wall, the length of rope depends on the crow flight distance of the connection end point B at the connection end point A of rope and rack inner wall and rope and sucker edge, crow flight distance in the time of should moving to inverted bowl type carrier openings Transverse plane greater than sucker bottom center's point between B point and the A point, and the crow flight distance between B point and the A point when moving to inverted bowl type carrier openings outermost end less than bottom center's point of sucker.

In order to prevent that sucker from sliding or rotate, and can evenly be provided with several rubbing cushions along the bottom surface outer rim of support on smooth plane.

When sucker protrudes in inverted bowl type support bottom surface outermost end, rope tension, the sucker edge is drawn perk; Apply certain down pressure to pull bar, make sucker press bright and clean stiff dough, the nut that turn matches with pull rod screw, make and move to bright and clean stiff dough by the affixed inverted bowl type support of the sliding sleeve of key and pull bar axial sliding fit, keep-up pressure simultaneously, make sucker press bright and clean stiff dough all the time, when the progressively approaching bright and clean stiff dough of inverted bowl type support, when rope is loose, sucker is discharged air in the chassis under pressure, tightly adhesive is on bright and clean stiff dough, and the inverted bowl type support continues to move to bright and clean stiff dough, behind the bright and clean stiff dough of contact, because the firm adhesive of sucker is on bright and clean stiff dough, the inverted bowl type support continues to make the suction of support by sucker downwards, tightly is pressed on the bright and clean stiff dough, forms strong bonded.At this moment, if reverse turn nut moves up the inverted bowl type support, rope is tensioning progressively, and the inverted bowl type support moves on continuing, and the sucker edge is drawn perk, air to enter in the sucker, and sucker has been taken off immediately.

Obviously, but adhesive of the present utility model, the sucker of having taken off, the using scope that exceeds existing sucker, can be widely used for being produced on the device that moves freely on the bright and clean stiff dough, the toy of walking freely is engaged in the device of sanitation and hygiene etc. on for example can bright and clean stiff dough in any direction on vertical windshield.

But adhesive of the present utility model, the sucker taken off are described further below in conjunction with accompanying drawing:

The structural representation of the sucker that but Fig. 1 is adhesive of the present utility model, taken off.

Fig. 2 is the C-C sectional view of Fig. 1.

As depicted in figs. 1 and 2, but adhesive of the present utility model, the sucker of having taken off, the sliding sleeve 5 that has key 10 in the central hole of an inverted bowl type support 3 affixed, the other end of sliding sleeve affixed one has the position-limited rack 7 of limited ring 8, between limited ring 8 and sliding sleeve 5 upper ends, establish a nut 6, be fixed in sucker 1 upper end be threaded 13 and the free end of the T of the falling ＂＂ character-shaped pull bar 2 of keyway 12 pass sliding sleeve 5 from the opening end of support 3, nut 6 and limited ring 8 are arranged on sucker 1 in the inverted bowl type support 3, the affixed end cap 9 on the top of pull bar 2, edge at sucker 8 joins by at least one rope 4 and support 3 upper inside wall, the length of rope 4 depends on the crow flight distance of the connection end point B at the connection end point A of rope and rack inner wall and rope and sucker edge, crow flight distance in the time of should moving to inverted bowl type support 3 portareapistons greater than sucker bottom center's point between B point and the A point, and the crow flight distance between B point and the A point when moving to inverted bowl type support 3 opening outermost end less than bottom center's point of sucker 8.In the bottom surface of support outer rim several rubbing cushions 11 are set evenly.
