Description

Suction cup structure improvement

The invention relates to a suction cup structure, in particular to a suction cup structure improvement by tightening and tightening suction.

Suction cups are common items in daily life. Due to their simple and convenient use, easy production and low price, they are widely used.

The principle of action of the suction cup mainly depends on a disc body facing the inner concave arc. When the disc body is pressed and deformed toward a smooth surface, the vacuum suction formed by the air in the concave arc is extruded. The force of absorbing a smooth surface is formed, and the freely locating suction cup is utilized to perform the functions such as hanging.

However, the fixing strength of the suction cup structure is easy to become hard, deformed, and lose elasticity after the suction cup material is lowered, resulting in a decrease or disappearance of the vacuum effect, so that the suction cup cannot be smoothly positioned on the wall surface and loses its effect; in addition, the structure of the suction cup Simple, the scope of application is naturally limited. Therefore, how to break through the framework of the existing suction cup structure and provide more perfect functions has become a topic to be discussed by relevant industry players.

In order to achieve the above-mentioned purpose of use, the technical proposal of the present invention is to provide a structural improvement of a suction cup comprising a strong suction cup, a suction cup cover and a knob; wherein the powerful suction cup comprises a suction cup body and a screw a pulling member, the screw pulling member is provided with a threaded portion and a joint portion; the suction cup body has elastic rubber, plastic material and the like, and is integrally formed at the joint portion, and the lower surface is slightly concave toward the center; the suction cup cover body is centrally disposed There is a perforation covering a cover body having a slightly smaller area than the suction cup body; a screw hole is formed at the lower end of the knob, and the internal thread of the screw hole corresponds to the external thread of the threaded portion.

The threaded portion of the suction cup body passes through the perforation of the suction cup cover, and the knob is screwed from the other side to the threaded portion so that the pressing edge of the periphery of the suction cup cover corresponds to the inner circumference of the suction cup body.

The above structure has the advantage that the suction cup structure of the present invention can generate a larger suction force than the conventional suction cup, and the suction cup cover is additionally designed with a functional configuration such as a hook, and can be used to carry a heavier load.

In order to further understand the structural features, technical means, efficacies and other features of the present invention, the preferred embodiments and the drawings are described in detail below.

Referring to Figures 1 and 2, there is shown a preferred embodiment of the improved suction cup structure, which is mainly composed of a powerful suction cup 10, a suction cup cover 20 and a knob 30. The strong suction cup 10 includes a suction cup body 11 and a screw puller 12, and the screw puller 12 is provided with a threaded portion 121 and a joint portion 122. The suction cup body 11 is made of elastic rubber, plastic or the like. The integral portion is formed at the joint portion 122, and the lower surface of the chuck body 11 is slightly recessed toward the center.

The suction cup cover 20 is centrally provided with a through hole 21 covering a cover body having a slightly smaller area than the suction cup body 11, and the through hole 21 provides the aforementioned screw pull member 12 to pass therethrough.

A screw hole 31 is formed at a lower end of the knob 30, and an internal thread of the screw hole 31 corresponds to an external thread of the threaded portion 121.

As shown in Fig. 2, the combination of the improved suction cup structure of the present invention is shown. The threaded portion 121 of the suction cup body 11 passes through the through hole 21 of the suction cup cover 20, and the knob 30 is screwed to the threaded portion 121 from the other side. The pressure edge 22 around the periphery of the suction cup cover 20 corresponds to the circumference of the suction cup body 11. When the chuck body 11 is pressed against the surface of the object, the chuck body 11 has a slight adsorption effect on the surface of the object.

As shown in FIG. 3, the state after tightening the knob 30 is indicated; when the knob 30 is tightened to screw the threaded portion 121 into the screw hole 31, the joint portion 122 pulls the suction cup body 11 and simultaneously presses the edge. 22 The force of pressing the periphery of the suction cup body 11 is strengthened, causing the suction cup body 11 to be in the middle of the suction cup cover 20. The deformation of the empty space is enhanced by the vacuum suction between the suction cup body 11 and the surface of the object, so that the suction cup structure of the present invention constitutes a strong fixing effect. To remove the suction cup, simply loosen the knob 30 in the reverse direction and return the suction force to the initial state, which is quite convenient.

The suction cup cover 20 of the present invention is a member having strength, so that the suction cup cover 20 can be additionally designed with a functional configuration, as shown in FIG. 4, which is a common hook 40 configuration. The new suction cup structure can provide a hanging function; since the suction cup structure of the present invention can generate a larger suction force than the conventional suction cup, it can be applied to carry a heavier load.

It can be seen from the above description that the present invention has achieved the preset purpose and can be used by the industry. Cheng has already met the requirements of the patent and has filed a patent application. The structure, the proportion, the size, the quantity, and the like of the embodiments are only in accordance with the disclosures of the specification, and are not intended to limit the scope of the present invention. Therefore, the scope of protection of the present invention is attached. The scope of the patent application is subject to change.
