JPH08128434A - Vacuum sucking cup provided with rotation stopper - Google Patents

Abstract

PURPOSE: To secure connection of a sucking pad and a pressing bowl body, so as to prevent a sucking pad sucking force from being deteriorated, by providing a locking device for connecting/integrating the sucking pad to/with the pressing bowl body, and preventing the rotation on a contact part of the sucking pad of a vacuum sucking cup with the pressing bowl body. CONSTITUTION: When a sucking cup is stuck to a glass surface W, a locking part 6 provided on a bowl edge part 5a of a pressing bowl body 5 is temporarily locked on a part to be locked 2 provided on the back surface of a sucking pad 1 on the glass surface W. The temporary connection of the pressing bowl body 5 to the sucking pad 1 is achieved. A pressing bowl body operating screw 7 is screwed to press the sucking pad 1 to the glass surface W through the movement of the pressing bowl body 5 and to lower the pressure inside the sucking pad 1. Accordingly, the sucking pad 1 is pressed to the glass surface W, and locking of the part to be locked 2 on the locking part 6 is achieved, and the pressing bowl body 5 and the sucking pad 1 are connected/integrated to/with each other. As a result, the pressing bowl body 5 is not rotated by itself even if external force is applied to the pressing bowl body 5, and the low pressure of the sucking pad 1 is not deteriorated, and therefore the sucking effect can be prevented from being deteriorated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum suction disk with a rotation stop capable of reliably sucking.

[0002]

2. Description of the Related Art As is well known, a vacuum suction plate device (vacuum suction plate tool) capable of suctioning a smooth surface such as a glass surface without scratches and hanging various items, or a vacuum suction plate for supporting a glass plate. Various vacuum suction discs used in a suspension device using a vacuum cleaner are useful. However, the structure of a normal suction cup is configured to suck by using a pressing force that is temporarily generated on the suction cup and a vacuum force generated by this pressing force. Therefore, there is a risk of desorption due to load, external pressure or unnecessary pressure (hereinafter simply referred to as external pressure), or the adsorption force weakens over time, so desorption with a slight external pressure. Or, there is a problem that the suspended product falls. From the above points, vacuum suction disk device by screw pressing and pressing bowl body, or used for suspending glass plate that exhibits suction effect with smooth surface and can adsorb without scratching this smooth surface There is a relatively large vacuum suction cup device that uses a crank lever and a pressing bowl that are used.

The following inventions and ideas are given as prior arts relating to the vacuum suction cup device. (1)
There is a device hook with a suction cup disclosed in JP-A-5-220042. The present invention is characterized in that the suction cup is pressed by the double presser bowl body and that the upper presser arm body is provided with the object support portion.
(2) There is a sucker attachment of No. 5-60374 of Kaikaidaira. This invention has a structure in which a pressing cylinder to which a pressing force is applied by a cam system is pressed and adsorbed on a peripheral wall surface of a suction cup. (3)
There is a mirror with a suction board of Jitsukaihei 4-1337773. This invention has a structure in which a suction cup is pressed and sucked through a crank lever type pressing bowl.

[0004]

The structure of pressing the suction cup with the pressing bowl body (using the pressing force) is certainly advantageous in that it can secure a strong suction force, but, for example, in the screw tightening method, the suction cup is Since the connection between the pressing bowl and the pressing bowl is not secured, the pressing force of the pressing bowl on the suction cup gradually declines due to the rotation of the pressing bowl, and ultimately, the removal of the suction disk There is a problem. In particular, in the structure in which the hook is directly or indirectly provided on the pressing bowl, the pressing bowl easily rotates when the article is engaged and disengaged, and the suction force of the suction cup is unknowingly lowered. However, there are problems such as accidentally causing a blunder. Further, in a vacuum suction disk sucked on a glass surface of a vehicle or the like, the above-mentioned situation is likely to occur due to factors such as vibration such as traveling vibration, shaking, and shock, and this is also a problem. In the crank system, the above situation is unlikely to occur directly, but the same problem still occurs.

[0005]

In view of the above, the present invention provides
The following configuration is adopted in order to connect the suction cup and the pressing bowl, and prevent the pressing bowl from rotating and the adverse effects caused by the rotation.

A vacuum suction disk with a rotation stopper according to the present invention is a vacuum suction disk that presses a suction disk with a pressing bowl, and the suction disk and the pressing bowl are located at a contact portion between the suction disk of the vacuum suction disk and the pressing bowl. The locking device is provided to prevent rotation such as integration with the body, tightening, integration, locking, and fixing.

[0007]

In order to suck the suction cup of the present invention on the glass surface, first, the suction cup is sucked on the glass surface. After that, on the locked portion provided on the back surface of the suction cup (the side opposite to the suction surface),
The locking portion provided on the bowl edge of the pressing bowl is temporarily locked (temporarily engaged). As a result, the pressing bowl and the suction cup can be temporarily connected to each other, and then the pressing bowl operation screw is screwed (operated) to press the suction cup against the glass surface through the movement of the pressing bowl. At the same time, the pressure inside the suction cup is reduced. Therefore, the suction cup is pressed against the glass surface, the locked portion and the locking portion are locked, and the pressing bowl and the suction cup are connected and integrated. Therefore, even if an external pressure (impact) is applied to the pressing bowl, the pressing bowl rarely rotates without permission, and the low pressure of the suction cup does not decline, so that the suction effect is prevented from lowering. Removal of the suction cup is almost the same as the conventional one, and the pressing bowl operating screw is unscrewed (operated) to release the pressing of the pressing bowl against the suction cup and release the connection between the locking part and the locked part. After that, the suction cup is removed from the glass surface.
