[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-4 shown, the present utility model provides a technical solution: a self-locking cylinder device for preventing the cylinder from retracting, including a cylinder body 1, and self-locking components are arranged on both side surfaces of the cylinder body 1;

[0025] The self-locking components include a connecting frame 2, a cylinder 3 and a piston 4. The connecting frame 2 is respectively fixedly installed on the top surface and the bottom surface of the cylinder body 1. The inner wall of the connecting frame 2 is fixedly installed with a cylinder 3. Both ends of the cylinder 3 are provided with openings in a penetrating manner. A piston 4 is movably connected to the inner wall of the cylinder 3, and the arc surface of the piston 4 is attached to the inner wall of the cylinder 3. An auxiliary self-locking component is arranged at one opening end of the cylinder 3. A connecting component is arranged between the front surface of the piston 4 and the arc surface of the movable rod of the cylinder body 1.

[0026] According to the overall structure of the device, when the movable rod of the cylinder body 1 extends, it will drive the connecting plate 8 to move together, thereby causing the connecting rod 5 connected to the connecting plate 8 to move, and enabling the piston 4 in the cylinder body 3 to move along the inner wall of the cylinder body 3. At this time, the distance between the electromagnet one 6 and the electromagnet two 7 is detected to change by the distance measuring sensor 10, so that the PLC controller 11 controls the electric push rod 9 to drive the electromagnet one 6 to move to the set distance from the electromagnet two 7, and simultaneously turns on the electromagnet one 6 and the electromagnet two 7, and makes them repel each other. Thus, when air leakage or the air source is cut off occurs in the cylinder body 1, the movable rod can be supported by the connecting rod 5 and the connecting plate 8 for self-locking. When the movable rod of the cylinder body 1 needs to contract, it is only necessary to control the electromagnet one 6 and the electromagnet two 7 to close through the PLC controller 11. And due to the settings of the WIFI module 12, the transmission antenna 13, and the WIFI filter 14, the PLC controller 11 can be remotely controlled.

[0027] As Figure 1 shown, the connecting component includes a connecting rod 5 and a connecting plate 8. An opening is provided through the middle of the front surface of the connecting plate 8, and the inner wall of the opening of the connecting plate 8 is fixedly connected to the arc surface of the movable rod of the cylinder body 1. One end of the connecting rod 5 passes through an opening at one end of the cylinder body 3 and is fixedly connected to the front surface of the piston 4, and the other end of the connecting rod 5 is fixedly connected to the back surface of the connecting plate 8.

[0028] By providing the connecting rod 5 and the connecting plate 8, when the movable rod of the cylinder body 1 moves, it will drive the connecting plate 8 and the connecting rod 5 to move together.

[0029] As Figures 2-3 shown, the auxiliary self-locking component includes an electric push rod 9 and an electromagnet one 6. The outer cylinder of the electric push rod 9 is fixedly installed on the inner wall of the opening at one end of the cylinder body 3. One end of the movable rod of the electric push rod 9 is fixedly installed with an electromagnet one 6. Control components are provided on the front surface of the electromagnet one 6 and the top surface of the cylinder body 1. An electromagnet two 7 is fixedly installed on the back surface of the piston 4. The control component includes a distance measuring sensor 10 and a PLC controller 11. The PLC controller 11 is fixedly installed at one end of the side surface of the cylinder body 1. The distance measuring sensor 10 is an infrared distance sensor. One end of the distance measuring sensor 10 is fixedly installed at the middle of the front surface of the electromagnet one 6. The distance measuring sensor 10 is electrically connected to the PLC controller 11. The PLC controller 11 is electrically connected to the electromagnet one 6, the electromagnet two 7, and the electric push rod 9 respectively. A wireless transmission component is provided at the connection of the PLC controller 11.

[0030] Through the set electric push rod 9, electromagnet 1 6, electromagnet 2 7, distance measuring sensor 10 and PLC controller 11, after the connecting rod 5 moves, the piston 4 will move. At this time, the distance measuring sensor 10 detects that the distance between the electromagnet 1 6 and the electromagnet 2 7 has changed, so that the PLC controller 11 controls the electric push rod 9 to drive the electromagnet 1 6 to move to the set distance from the electromagnet 2 7, and at the same time turns on the electromagnet 1 6 and the electromagnet 2 7 and makes them repel each other. Thus, when there is air leakage or the air source is cut off in the cylinder body 1, the movable rod can be supported by the connecting rod 5 and the connecting plate 8 to perform self-locking.

[0031] As Figure 4 shown, the wireless transmission component includes a WIFI module 12 and a transmission antenna 13. The connection end of the WIFI module 12 is plugged into the connection end of the PLC controller 11. A connection port is fixedly installed on the side of the shell of the WIFI module 12 and is electrically connected to the WIFI module 12. The transmission antenna 13 is plugged into the connection port of the WIFI module 12 and is electrically connected to the WIFI module 12. The transmission antenna 13 is an adjustable external antenna, and a WIFI filter 14 is welded on the surface of the PCB board of the WIFI module 12.

[0032] Through the set WIFI module 12, transmission antenna 13 and WIFI filter 14, the PLC controller 11 can be remotely controlled through the WIFI module 12, and due to the settings of the transmission antenna 13 and the WIFI filter 14, the range and quality of the signal received or transmitted by the WIFI module 12 can be better.

[0033] Working principle: When the movable rod of the cylinder body 1 extends, it will drive the connecting plate 8 to move together, so that the connecting rod 5 connected to the connecting plate 8 moves, and the piston 4 in the cylinder body 3 moves on the inner wall of the cylinder body 3. At this time, the distance measuring sensor 10 detects that the distance between the electromagnet 1 6 and the electromagnet 2 7 has changed, so that the PLC controller 11 controls the electric push rod 9 to drive the electromagnet 1 6 to move to the set distance from the electromagnet 2 7, and at the same time turns on the electromagnet 1 6 and the electromagnet 2 7 and makes them repel each other. Thus, when there is air leakage or the air source is cut off in the cylinder body 1, the movable rod can be supported by the connecting rod 5 and the connecting plate 8. When the movable rod of the cylinder body 1 needs to contract, the electromagnet 1 6 and the electromagnet 2 7 can be controlled to close by the PLC controller 11, and due to the settings of the WIFI module 12, the transmission antenna 13 and the WIFI filter 14, the PLC controller 11 can be remotely controlled.
