Abstract
The invention provides a sucking disc comprising a sucking disc body and a hook, wherein the sucking disc body is made of PVC (polyvinyl chloride) adhesive films; a sucking surface coming into suction contact with a surface to be sucked is formed on the surface on one side of the thickness direction, and a back surface is formed on the surface of the other side thereof; and the hook constituting a part of the sucking disc is glued to the back surface with glue. The PVC adhesive films can be securely attached to a smooth surface, thus creating the fundamentally vacuum state between the sucking surface of the PVC adhesive films and the surface to be sucked; moreover, the PVC adhesive films have good adhesiveness, thereby effectively avoiding the problem that the sucking disc is detached due to the vacuum leak; furthermore, the hook can be securely attached to the surface to be sucked through the PVC adhesive films.
Description
Affiliated technical field
The present invention relates to a kind of sucker.
Background technique
The sucker that is used for article are attached to room wall for example or Vehicular instrument panel is known.
Usually, this sucker comprises by rubber, and PVC etc. form disc-shape, and form along a side surface of its thickness direction will be in treating that absorption surface carries out the sorption face of sorption contact, and its opposite side surface forms the back side.
When using sucker, the sorption face of making is in the face for the treatment of absorption surface, the central part of sorption face is pressed against treats on the absorption surface, by this at the sorption face of sucker with describedly treat to produce between the absorption surface vacuum state basically, and keep this vacuum state by the elastic force of sucker, thereby make sucker keep contacting with the sorption for the treatment of absorption surface.
Because the sucker that adopts made such as thermoplastic elastomer (TPE) or rubber is when bearing its object weight that bears, easy deformation or generation gas leakage, so the object weight that bears has only about 1KG, in order to address this problem, Chinese patent 96120270.X, 91204294.X, 98248552.2,01239187.5 all disclose a kind of sucker that has the bowl-type housing etc. patent, its principle be utilize the edge of bowl-type housing fasten sucker the edge and to the certain pressure of formation, make the contacting part of sucker and body surface have good seal, but these products all need to increase 3-4 annex, the structure more complicated, cause the rising of cost, and because bowl-type housing, parts such as nut have been arranged, the volume ratio of sucker is bigger, and its application has been had more restriction.
Summary of the invention
Simultaneously, less according to the sucker sorption face of correlation technique, because they all are to keep this vacuum state by the elastic force of sucker, thereby make sucker keep contacting with the sorption for the treatment of absorption surface.Therefore, when sucker kept being in the sorption contact condition for a long time, the shape of sucker may be out of shape or follow the string, and vacuum leak just takes place sucker, thereby causes the disengaging of sucker.
Thereby, need a kind ofly to prevent favourable sucker aspect the vacuum leak improving it.
In order to satisfy above-mentioned needs, according to one embodiment of present invention, a kind of sucker is provided, comprise sucker body and hook, the sucker body is formed by the PVC pad pasting, and form along a side surface of its thickness direction will be in treating that absorption surface carries out the sorption face of sorption contact, and its opposite side surface forms the back side, as the part of sucker, hook fastens with glue and goes up overleaf.Because the PVC pad pasting can well be attached on the smooth face, by this at the sorption face of PVC pad pasting with describedly treat to produce between the absorption surface vacuum state basically, and because the PVC pad pasting has good adhesive quality, so can effectively prevent to cause the problem of the disengaging of sucker, and hook is attached to by the PVC pad pasting with being stabilized and treats on the absorption surface because vacuum leak takes place.
The invention has the beneficial effects as follows: adsorption force is big, and the retention time is long, and is simple in structure, and cost is low.

1.PVC pad pasting sorption face among the figure, 2. hook, 3. binding face, the 4.PVC pad pasting back side, 5 annular portions
Embodiment
In Fig. 1 and Fig. 2, PVC pad pasting (1) and hook (2) are bonded into one by glue, PVC pad pasting (1) is oval sheet, binding face (3) also is oval sheet, binding face (3) on the hook (2) is bonded in the central position at the PVC pad pasting back side (4), and the binding face (3) of hook on (2) be less than PVC pad pasting sorption face (1), make PVC pad pasting (1) remove with the bonding part of binding face (3) an annular portion (5) in addition.
Claims (4)
1. sucker, comprise the pvc pad pasting, hook, it is characterized in that: pvc pad pasting and hook are bonded into one by glue, described pvc pad pasting is as the sucker body, and the side surface along its thickness direction forms and will carry out the sorption face that sorption contacts with treating absorption surface, and its opposite side surface forms the back side, and described hook is as the part of sucker.
2. sucker according to claim 1 is characterized in that: described pvc pad pasting is oval circular or smooth-going camber line profile, and thickness is preferably between the 0.2mm-0.5mm.
3. sucker according to claim 1, it is characterized in that: as the part of sucker body and the bonding center that is positioned described pvc pad pasting of hook that provides, described stick portion is less than the profile of described pvc pad pasting, and makes except that described PVC pad pasting and hook and circularized by the PVC pad pasting the bonding part of glue.
4. sucker according to claim 1 is characterized in that: described hook is formed by plastic material.
