Description

A leak-resistant suction cup

technical field

The utility model relates to a suction cup, in particular to an anti-leakage suction cup.

Background technique

At present, ordinary suction cups are used to pick up objects. When the suction cup is not fully attached to the object to be sucked, some leakage will cause the vacuum of the entire suction cup system to fail to be established, resulting in reduced reliability of the suction cup and affecting the use of the suction cup, especially for rough The reliability of this kind of suction cup for objects will be further reduced, and even cannot be sucked. Therefore, there is a need for a leak-resistant, highly reliable suction cup.

Utility model content

The purpose of the utility model is to provide an anti-leakage sucker with high reliability and anti-leakage.

In order to achieve the above object, the utility model adopts the following technical solutions:

An anti-leakage suction cup, comprising a rigid suction cup shell with a concave cavity on the surface of the disk connected to a suction hole, characterized in that there are uniformly distributed convex columns in the concave cavity of the rigid suction cup casing, and a thin suction plate covers the concave cavity The cavity is supported by the convex column, and the periphery of the rigid suction cup shell is provided with an annular sealing ring groove to place a sealing ring, and a sponge cushion is fixedly connected to the thin suction plate.

The above-mentioned thin suction plate is densely covered with tiny suction holes, and the thin suction plate is connected with the rigid suction cup shell through fastening screws, or through 1/4 turn quick-lock fasteners and the rigid suction cup shell to realize quick installation and disassembly .

The above-mentioned spongy buffer pad has air-breathing through-holes connected with the tiny suction holes of the thin suction plate, and the spongy buffer pad is bonded to the thin suction plate by a universal glue.

Compared with the prior art, the utility model has the following obvious features and advantages. The thin suction plate of the utility model is densely covered with tiny suction holes. When the suction cup is not fully attached to the object to be sucked, some of the tiny suction holes leak. Due to the throttling effect of the tiny suction holes, the establishment of vacuum in the rigid suction cup shell is not affected, and it has the effect of anti-leakage. The utility model is suitable for absorbing any package with a smooth surface, and can also absorb a package with a rough surface, such as a rough board.

Detailed ways

A preferred embodiment of the present utility model is: referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the anti-leakage suction cup includes a rigid suction cup housing 1 with a concave cavity 9 on the disk surface, a thin suction plate 2, and a sealing ring 3 , Sponge cushion 4. The concave cavity 9 of the rigid suction cup housing 1 has a convex column 8, which supports the above-mentioned thin suction plate 2. The bottom surface of the rigid suction cup housing 1 has an air extraction hole 6, and an annular sealing ring is opened around it. Groove 11; the above-mentioned thin suction plate 2 has uniformly densely distributed tiny suction holes 7, and the thin suction plate 2 realizes quick installation and disassembly through the 1/4-turn quick-lock fastener 5 and the rigid suction cup housing 1; the above-mentioned sealing The ring 3 acts as a seal between the rigid suction cup housing 1 and the thin suction plate 2; the above-mentioned spongy buffer pad 4 has an air suction through hole 10 connected with the tiny suction hole 7 of the above-mentioned thin suction plate 2, and the spongy buffer pad 4. The spongy buffer pad 4 is bonded with the above-mentioned thin suction plate 2 by the universal glue, and the spongy buffer pad 4 plays a role of reducing impact when the suction cup is in contact with the sucked object, and also plays a role of sealing.
