Meanwhile, the terms "a", "an", "two", "upper" and the like used in the present specification are for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered as the scope of the present invention without substantial changes in the technical content.

Please refer to fig. 1, fig. 2 and fig. 3, which are a schematic perspective view, a schematic exploded perspective view and a schematic sectional structure of a preferred embodiment of the present invention. The utility model relates to a combined type vacuum cylinder, vacuum cylinder 1 mainly includes cylinder shell 10, first cylinder end 11, second cylinder end 12, vacuum suction body 13 and vacuum inner tube 14, wherein cylinder shell 10 both ends set up first cylinder end 11 and second cylinder end 12 respectively, cylinder shell 10 is defined to have respectively with first cylinder end 11 and the communicating accommodation space 100 of second cylinder end 12, wherein first cylinder end 11 sets up a vacuum suction hole 110 and one with the communicating first air inlet 112 of accommodation space 100, second cylinder end 12 sets up an exit 120 and a communicating second air inlet 122 with accommodation space 100. The vacuum suction pipe 13 is disposed in the accommodating space 100 and changes an operation state of the accommodating space 100 by the gas pressure of the first gas inlet 112 and the second gas inlet 122 to determine to extend or retract toward the inlet/outlet 120, and the vacuum inner pipe 14 is disposed in the vacuum suction pipe 13 and communicates with the vacuum suction hole 110 for the vacuum suction pipe 13 to suck the object in a vacuum manner.

In addition, the vacuum suction pipe further includes a piston structure 15 disposed at one end of the vacuum suction pipe 13 and located in the accommodating space 100. One end of the vacuum suction pipe body 13 is provided with a vacuum suction part 130.

Furthermore, the second cylinder head 12 is further provided with an air adjustment valve 124, and the operation speed of the piston structure 15 can be adjusted by the air adjustment valve 124.

Fig. 4 and 5 are also shown, which are a schematic diagram of a first operating state and a schematic diagram of a second operating state according to a preferred embodiment of the present invention. In fig. 4, for example, to intake air from the first cylinder head 11 to suck the article, an external pressurizing device is first used to drive air pressure into the first air inlet 112 of the first cylinder head 11 (solid arrow), and at this time, the piston structure 15 located in the accommodating space 100 is pushed, because the piston structure 15 is disposed at one end of the vacuum suction tube 13, when the piston structure 15 moves, the vacuum suction tube 13 is naturally driven to move toward the inlet/outlet 120 of the second cylinder head 12 and extend out (solid arrow), and while moving, the vacuum suction hole 110 on the first cylinder head 11 is connected to an external vacuum-pumping device, and a vacuum state (dotted arrow) is generated in the vacuum suction tube 13 through the vacuum inner tube 14 disposed in the vacuum suction tube 13.

After the vacuum suction pipe 13 moves out of the inlet/outlet 120, the vacuum suction portion 130 on the vacuum suction pipe 13 sucks the article in a vacuum manner to achieve a complete suction state, after the suction is completed, the first air inlet 112 of the first cylinder head 11 stops air intake, the second air inlet 122 of the second cylinder head 12 inputs air pressure through the pressurizing device and pushes the piston structure 15 back to retract the vacuum suction pipe 13 from the inlet/outlet 120 (solid arrow), so that the sucked article moves upward, and then the article can be separated from the vacuum suction portion 130 of the vacuum suction pipe 13 after the external vacuum pumping device is stopped.

The structural equipment can greatly improve the problem of needing larger installation space, and simultaneously simplifies the assembly process to improve the assembly efficiency.
