Abstract

Provided is a vacuum fixer facilitating repeated fixing use. A disk periphery of a sucking disk body is formed with a combination edge for covering and combining a sealing frame ring to constitute a mutual complement effect, so that when the vacuum fixer changes positions or is re-fixed onto a sucking surface or is repeatedly fixed onto different sucking surfaces for use, the combination edge is able to provide a support inside the soft sealing frame ring to achieve the benefit of maintaining the shape and function of the sealing frame ring for a long term. In particular, when a sealing attachment surface of the sealing frame ring is lifted off the sucking surface, the combination edge of the sucking disk body is driven so that when the vacuum fixer is not in use, air can directly enter the sucking disk body by only lifting a corner of an outer edge of the sealing frame ring thereby increasing operation convenience when the vacuum fixer is removed from the sucking surface.

Description

Vacuum holder for advantageous re-use

The present invention relates to a vacuum holder capable of maintaining the shape and effect of the frame ring body for a long period of time in repeated use, and which can improve the convenience of operation when removed from the suction surface, especially an advantageous overlap fixing. Vacuum holder used.

In general, it is difficult to suspend or fix certain items on a tiled wall or a glass surface with screws or nails. Vacuum holders manufactured according to the principle of suction cups on octopus legs have been widely used; The holder has a dish-like suction cup similar to the inverted buckle. After the suction cup is placed on a smooth surface (such as glass or ceramic tile), and the internal air of the suction cup is discharged, when the internal volume of the suction cup is forced to increase, the external pressure of the suction cup (ie, atmospheric pressure) is higher than the internal pressure of the suction cup. Therefore, since the atmospheric pressure applies pressure to the suction cup, the vacuum holder can be attached to the attachment surface.

Japanese Utility Model No. 61-109367 (published on Jul. 11, 1986) discloses a vacuum holder; however, after being used for a long time, the vacuum holder will seriously affect its adsorption force due to hardening of the suction cup. In particular, when the attachment surface is formed with a slit or a zigzag pattern, since the suction cup cannot form a complete vacuum wall, it can no longer be attached to the attachment surface.

In order to solve the above problems in the prior art, Japanese Utility Model Patent No. 3014841 (issued June 7, 1995) discloses a vacuum holder having a screw shaft mounted on the upper center of the suction cup for Insert the screw shaft into it and cover the suction cup a dome-shaped pressure plate on the surface of the portion, and a handle connected to the screw shaft extending from the upper portion of the pressure plate. Using a binder, a ductile binder material (such as a binder resin) is bonded to the edge of the suction side of the suction cup.

It is a good attempt to increase the bonding force of the suction cup by using a ductile adhesive material. However, since the suction cup is mainly made of a flexible material, the center of the suction cup is lifted toward the pressure plate to widen the internal volume of the suction cup. At the time, the shape of the edge of the suction cup may be deformed, or a slight slip may occur between the suction surface and the attachment surface. In particular, if there is a sawtooth portion on the attachment surface, this prior art will not provide the desired bonding force.

In addition, Chinese Patent No. ZL200480029868.9 also discloses a vacuum holder in which a vacuum wall made of gel-type polyurethane extends from the bottom of the pressure plate along the edge of the pressure plate toward the attachment surface, and has an inclination toward the center of the pressure plate. The pressure surface is in contact with the inclined surface of the suction cup; when the pressure plate makes the inside of the suction cup into a vacuum state, the slit or the serrated portion on the attachment surface can be filled by the gel-type vacuum wall, so that the inside of the suction cup is kept under vacuum; The vacuum holder is fixed on the attachment surface, and is not limited to long-term fixation, and more often, it is temporarily fixed or has multiple repeated fixation requirements for transposition on different attachment surfaces; the above-mentioned conventional vacuum fixation If the device is to be removed from the attachment surface, in addition to the operation of the screw fastener, the internal volume of the widened suction cup should be recovered, and the external air must be allowed to enter the inside of the suction cup, so that the vacuum holder can be easily removed from the attachment surface. Only the vacuum wall made of gel-type polyurethane has good viscosity and high elongation, although it has a good cutting effect on the outside air, but it has good recovery after elongation. The problem of capacity, repeated expansion deformation (circle relaxation) caused by tearing from the attachment surface, often affects the tightness effect, and may even be separated from the suction plate ascending surface due to partial inclined pressure surface (not fully transferred) Losing the blocking ability of air entering the inside of the suction cup, sometimes even if part of the vacuum wall has completed the tearing from the attachment surface However, the suction cup located at the inner edge of the vacuum wall may be adsorbed on the attachment surface. Since the outside is not easy to touch the edge of the suction cup to perform the operation of dialing away from the attachment surface, it is troublesome and inconvenient for repeated use for a long time.
