Elastic rubber body for sucker

Abstract

The utility model discloses an elastic rubber body for a suction cup. The elastic rubber body comprises a supporting part and a connecting rod arranged on the supporting part, an adsorption part is further arranged on the outer edge of the supporting part, and a gluing groove is formed between the supporting part and the adsorption part. When the glue is in contact with the contact surface, due to the fact that the glue is filled in the glue coating groove, air between the glue and the contact surface can be reduced while primary positioning of the glue is achieved, and therefore it is guaranteed that the adsorption part can be reliably adsorbed to the contact surface, and particularly, the outer end face of the supporting part is higher than the outer end face of the adsorption part. Therefore, when the colloid is in contact with the contact surface through the supporting part and then is in contact with the contact surface through the adsorption part, air remaining in the colloid can be further reduced. On the basis, the device is worthy of popularization and application.

Description

Technical Field

[0001] The utility model relates to the technical field of suction cups, in particular to an elastic colloid used for the suction cup. Background Art

[0002] Existing suction cups, such as those disclosed in publication number CN105179440A or CN106122240B, have a circular colloid portion, and the side of the colloid portion facing the contact surface is arc-shaped. Consequently, when the colloid portion contacts the contact surface, the arc-shaped colloid portion makes it difficult to expel air quickly at the moment of contact, resulting in air remaining in the colloid portion, which in turn affects the adsorption time of the colloid portion on the contact surface. Utility Model Content

[0003] The purpose of the present invention is to provide an elastic colloid for a suction cup to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an elastic colloid for a suction cup, comprising a support portion and a connecting rod arranged on the support portion; an adsorption portion is also provided on the outer edge of the support portion; wherein, the side of the support portion facing the contact surface is a plane, and a glue coating groove is formed between the support portion and the adsorption portion.

[0005] As a preferred technical solution of the present invention: the support portion is in the shape of an elongated strip.

[0006] As a preferred technical solution of the present invention: the side of the supporting portion facing the contact surface is higher than the side of the adsorption portion facing the contact surface.

[0007] As a preferred technical solution of the present invention: a keel is further provided in the support portion, and the connecting rod is fixed on the keel.

[0008] As a preferred technical solution of the present invention: the keel and the support portion are integrally formed.

[0009] As a preferred technical solution of the present invention: a protrusion is further provided on the keel, and the protrusion supports the two surfaces of the support part from the inside of the support part at the same time.

[0010] As a preferred technical solution of the present invention: there are multiple protrusions, and the multiple protrusions are evenly spaced in the length direction of the keel.

[0011] As a preferred technical solution of the present utility model: through holes are evenly distributed on the keel.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are as follows: 1. Since the side of the support portion facing the contact surface is flat, the support portion can quickly discharge air when in contact with the contact surface to reduce the amount of residual air between the support portion and the contact surface;

[0013] 2. When the colloid contacts the contact surface, since the glue coating groove is filled with glue, the initial positioning of the colloid can be achieved while reducing the air between the colloid and the contact surface, thereby ensuring that the adsorption part can be reliably adsorbed on the contact surface.

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0020] See also Figure 1-4 The utility model provides an embodiment: an elastic colloid for a suction cup, comprising a support portion 3 and a connecting rod 2 arranged on the support portion 3; the outer edge of the support portion 3 is also provided with an adsorption portion 1; wherein, the side of the support portion 3 facing the contact surface is a plane, and a glue coating groove 4 is formed between the support portion 3 and the adsorption portion 1.

[0021] To sum up, since the side of the support part 3 facing the contact surface is flat, the support part 3 can quickly discharge air when it contacts the contact surface to reduce the amount of residual air between the support part and the contact surface; in particular, when the colloid contacts the contact surface, since the glue coating groove 4 is filled with glue, the air between the colloid and the contact surface can be reduced while achieving the initial positioning of the colloid, thereby ensuring that the adsorption part 1 can be reliably adsorbed on the contact surface.

[0022] Furthermore, since the support portion 3 is in the shape of an elongated strip, the entire colloid is also in the shape of an elongated strip. When the elongated support portion 3 contacts the contact surface, the contact area between the support portion 3 and the contact surface can be expanded, so that the contact between the colloid and the contact surface is more stable, which facilitates the initial positioning of the colloid when in contact with the contact surface. At the same time, since the support portion 3 is in the shape of an elongated strip, the adsorption portion 1 surrounding the outer edge of the support portion 3 is also in the shape of an elongated strip, thereby increasing the contact area between the adsorption portion 1 and the contact surface, thereby improving the adsorption force of the colloid.

[0023] Furthermore, since the side of the support portion 3 facing the contact surface is higher than the side of the adsorption portion 1 facing the contact surface, when the colloid first contacts the contact surface through the support portion 3 and then contacts the contact surface through the adsorption portion 1, the air remaining in the colloid can be further reduced.

[0024] On the basis of the above scheme, since a keel 6 is also provided in the support part 3, and the connecting rod 2 is fixed on the keel 6; therefore, the keel 6 can be used to enhance the structural strength of the support part 3 to avoid the device falling off due to deformation of the support part 3. At the same time, it also enables the support part 3 to move synchronously, and then enables the support part 3 to drive the adsorption part 1 to move as a whole, so that all parts of the adsorption part 1 can be synchronously adsorbed on the contact surface.

[0025] Furthermore, the keel 6 and the support portion 3 are integrally formed, that is, the colloid is wrapped around the outside of the keel 6 during molding; therefore, the keel 6 will not easily be displaced during operation.

[0026] Furthermore, the keel 6 is provided with a protrusion 5, which simultaneously supports both surfaces of the support portion 3 from within the support portion 3. Specifically, there are multiple protrusions 5, and these protrusions 5 are evenly spaced along the length of the keel 6. This increases the number of contact points between the support portion 3 and the keel 6 during molding, thus strengthening the contact points between the support portion 3 and the keel 6. Furthermore, the keel 6 prevents deformation of the support portion 3 after the colloid support portion 3 contacts the contact surface.

[0027] In addition, since the through holes 7 are evenly distributed on the keel 6, the material of the support part 3 can enter the through holes 7 when the support part 3 and the keel 6 are formed, so that the keel 6 and the support part 3 have stable and reliable structural strength after forming.

[0028] In summary, while this device is simple, the optimized shape of the colloid ensures stable and reliable adsorption to the contact surface. Furthermore, the presence of structures such as the keel 6 ensures the colloid's inherent structural strength, preventing it from easily falling during use. In particular, the strip shape of the colloid allows for a large surface area of ​​contact with the wall. This allows for the device to utilize fewer suction cups, achieve greater adsorption strength, and provide a more durable hold when installed on a shelf of the same size.

[0029] The two gluing tanks can both be filled with polyether polyol glue. Specifically, two polyether polyol types, A-5250 and B-688, are mixed and then filled into the two gluing tanks.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
