[0002] Suction cups are often used in daily life. Existing suction cup devices are generally used for direct adsorption, especially suction cups used on the bottom of objects, which are generally not easy to remove. In addition, general suction cups only have adsorption function and no positioning function during use, and are not suitable for some special occasions. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the utility model provides a double-sided pneumatic suction cup, which separates the two suction cup structures and connects them to two different vacuum devices.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A double-sided pneumatic suction cup includes a suction cup shell, an upper suction cup, an upper suction cup air nozzle, a lower suction cup, and a lower suction cup air nozzle. The upper suction cup and the lower suction cup are arranged on opposite surfaces of the suction cup shell, the upper suction cup is connected to the upper suction cup air nozzle, and the lower suction cup is connected to the lower suction cup air nozzle. The connecting angle between the lower suction cup air nozzle and the lower suction cup is also connected to a through external exhaust pipe. A disassembly device is installed in the external exhaust pipe. The three-way hole formed by the lower suction cup air nozzle, the lower suction cup and the external exhaust pipe is sealed and matched with the disassembly device.

[0006] Furthermore, the diameter of the through outer exhaust pipe gradually decreases.

[0007] Furthermore, the disassembly device is installed in the external exhaust duct through an elastic member and a sealing cover, and a groove is provided on the protruding column of the disassembly button.

[0008] Furthermore, when the disassembly button is pressed and moves inward, the groove moves to the position of the three-way hole formed by the lower suction cup air nozzle, the lower suction cup and the external exhaust pipe.

[0009] Furthermore, a limiting column is provided on the suction cup shell of the double-sided pneumatic suction cup.

[0010] Furthermore, the limiting column is arranged on one side of the upper suction cup.

[0011] Furthermore, the upper suction cup air nozzle and the lower suction cup air nozzle are respectively connected to different vacuum extraction devices.

[0012] The beneficial effects of the present invention are as follows: the double-sided pneumatic suction cup has two suction cup structures that are symmetrical in upper and lower surfaces; the two suction cups are separated and connected to two different vacuum pumping devices; the lower suction cup can be deflated by pressing a manual button, thereby easily moving the suction cup; the double-sided pneumatic suction cup can also be provided with a limit column on the shell on one side of the upper suction cup, which is used to adsorb and position objects during use; the limit column can clamp the object, limit it, and prevent it from shifting during operation.

[0020] The following further describes the embodiments of the present invention with reference to the accompanying drawings.

[0021] like Figures 1 to 6As shown, a double-sided pneumatic suction cup has an upper suction cup 1 and a lower suction cup 2 disposed on opposite sides of the double-sided pneumatic suction cup. The upper suction cup 1 is connected to the upper suction cup air nozzle 3, and the lower suction cup 2 is connected to the lower suction cup air nozzle 4. The connecting angle between the lower suction cup air nozzle 4 and the lower suction cup 2 is also connected to a through-hole external exhaust duct 5. A disassembly device is installed in the external exhaust duct 5. The three-way hole 6 formed by the lower suction cup air nozzle 4, the lower suction cup 2, and the external exhaust duct 5 is sealed with the disassembly device. The diameter of the through-hole external exhaust duct 5 gradually decreases. The disassembly device is installed in the external exhaust duct 5 via a compression spring 7 and a sealing cover 8. The boss 10 of the disassembly button 9 is provided with a groove 11. When the disassembly button is pressed, the groove 11 moves to the position of the three-way hole 6 formed by the lower suction cup air nozzle 4, the lower suction cup 2, and the external exhaust duct 5. The upper suction cup air nozzle 3 and the lower suction cup air nozzle 4 are respectively connected to two independent vacuum pumping devices.

[0022] According to the needs of use, a variation of the double-sided pneumatic suction cup is to provide a limiting post 13 on the suction cup housing 12 , and the limiting post 13 is provided on one side of the upper suction cup 1 .

[0023] Double-sided pneumatic suction cups are used as fixtures during sheet metal tapping. One suction cup secures the sheet metal, while the other is fixed to the work surface of the tapping machine. At least four double-sided pneumatic suction cups are installed on the work surface, and at least two of them are equipped with limit posts. The double-sided pneumatic suction cups with limit posts are positioned on opposite sides of the sheet metal. This not only positions the sheet metal, but also prevents it from rotating and shifting during the tapping process. Furthermore, the pneumatic suction cups provide support, tightening the sheet metal with suction and releasing it when the suction stops, making it easier to replace the sheet metal. The lower pneumatic suction cup can be moved at any time by pressing the disassembly button, making it quick and easy to use.

[0024] When replacing the sheet metal, the vacuum device connected to the upper suction cup air nozzle stops working, and the upper suction cup releases the sheet metal. When the position of the double-sided pneumatic suction cup needs to be changed, the disassembly button is manually pressed, and the vacuum device connected to the lower suction cup air nozzle stops working, the suction cup is released from the work surface, and the double-sided pneumatic suction cup is manually moved to the desired position.

[0025] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the present invention specification, or directly or indirectly applied to the technical fields of other related products, are also included in the patent protection scope of the present invention.
