[0002] Oil cylinders are widely used in various fields, especially in mechanical manufacturing, automobile manufacturing, metallurgical industry, chemical industry, construction industry and environmental protection field, etc. The piston type oil cylinder is the most common type of oil cylinder. When hydraulic oil enters from the left end inlet hole and acts on the left end of the piston, it will push the piston to move in the axial direction to the right, thereby pushing the components connected with the piston rod to move to the right. Conversely, when hydraulic oil enters from the right end inlet hole and acts on the right end of the piston, the piston will move to the left.

[0003] The supporting effect of the traditional oil cylinder piston rod is not good. When the oil cylinder bears a large load or generates a large lateral force during work, the piston rod is easy to bend or lose stability, resulting in a decrease in the performance of the oil cylinder or even damage. Therefore, there are certain disadvantages.

[0020] The application will be further described below in conjunction with the accompanying drawings. Figure 1 - Figure 4 The application will be further described below in conjunction with the accompanying drawings.

[0021] The double support oil cylinder piston rod, referring to Figure 1 - Figure 4 , including the cylinder body 1, the inside of the cylinder body 1 is installed with the piston 2, one end of the piston 2 and extending to the outside of the cylinder body 1 is installed with the piston rod 3, the outside of both ends of the cylinder body 1 is symmetrically installed with the reinforcing arc block 4, the outer ring surface of the reinforcing arc block 4 is installed with the first connecting block 5, one side of the outside of the reinforcing arc block 4 is installed with the fixed arc plate 6, the outer arc surface of the fixed arc plate 6 is installed with the limiting tube 7, the outer ring surface of the piston rod 3 is provided with the round pipe 8, both ends of the outside of the round pipe 8 is symmetrically installed with the second connecting block 9, one end of the outside of the second connecting block 9 is installed with the support rod 10, the inner side wall top and bottom end of the round pipe 8 is provided with the threaded rod 11, one end of the threaded rod 11 and located outside of the piston rod 3 is installed with the limiting arc block 12.

[0022] Referring to Figure 1 - Figure 4 , one end of the threaded rod 11 away from the limiting arc block 12 is installed with the handle 13, the threaded rod 11 is rotatably connected between one end and the outside of the limiting arc block 12, and the outer ring surface of the threaded rod 11 is threadedly connected with the inside of the round pipe 8, rotating the handle 13 drives the threaded rod 11 to rotate inside the round pipe 8, since the outer ring surface of the threaded rod 11 is threadedly connected with the inside of the round pipe 8, rotating the handle 13 can make the threaded rod 11 along the round pipe 8 and in turn drive the limiting arc block 12 to tighten or loosen the piston rod 3, which facilitates the installation of the round pipe 8 on the outside of the piston rod 3, the inner side wall of the limiting arc block 12 is provided with the anti-skid pad 14, which increases the friction between the limiting arc block 12 and the piston rod 3, preventing the piston rod 3 from slipping between the two limiting arc blocks 12 when moving, which affects the stability of the two support rods 10.

[0023] Referring to Figure 3 - Figure 4 , one end of the support rod 10 passes through the inside of the limiting tube 7 and then penetrates the first connecting block 5 and extends to the outside thereof, the outer ring surface of the support rod 10 is slidingly connected with the inside of the limiting tube 7 and the first connecting block 5, when the piston rod 3 moves synchronously to drive the support rod 10 to move, the support rod 10 will slide inside the limiting tube 7 and the first connecting block 5, thereby maintaining the relative stability with the cylinder body 1 and the piston rod 3, and through the double support, the oil cylinder piston rod can adapt to different working conditions.

[0024] Referring to Figure 3 - Figure 4The outer ring surface of the end of the support rod 10 away from the second connecting block 9 is provided with threads. A limit ring 15 is provided on the thread at one end of the second connecting block 9. The inner side wall of the limit ring 15 is threadedly connected to one end of the support rod 10. By rotating the limit ring 15, it can be installed on one end of the support rod 10, which facilitates the installation of the support rod 10 on the limit tube 7 and the first connecting block 5, and prevents the support rod 10 from detaching from the limit tube 7 and the first connecting block 5. Several sets of reinforcing ribs 16 are provided at both ends of the limit tube 7 and on the outer arc surface of the fixed arc plate 6. The reinforcing ribs 16 not only enhance the structural strength of the fixed arc plate 6, but also improve the connection stability between the limit tube 7 and the fixed arc plate 6. This design enables the piston rod of the double-supported hydraulic cylinder to maintain the integrity and stability of the structure when subjected to a large load.

[0025] Reference Figure 1 - Figure 2 The cylinder body 1 and piston rod 3 are each equipped with an installation ring 17 at one end. The cylinder body 1 is symmetrically equipped with oil inlets 18 at both ends. The installation ring 17 facilitates the installation of the piston rod of the double-supported cylinder. At the same time, the cylinder body 1 is symmetrically equipped with oil inlets 18 at both ends for injecting hydraulic oil into the cylinder body 1.

[0026] The implementation principle of the double-support hydraulic cylinder piston rod in this embodiment is as follows: During the use of this device, mounting rings 17 are installed at one end of both the cylinder body 1 and the piston rod 3. The mounting rings 17 facilitate the installation of the hydraulic cylinder piston rod, allowing it to be easily connected to the hydraulic system. Oil inlets 18 are symmetrically installed at both ends of the cylinder body 1. These oil inlets 18 are used to inject hydraulic oil into the cylinder body 1, thereby driving the movement of the piston 2 and piston rod 3. When hydraulic oil is injected into the cylinder body 1 through the oil inlets 18, the hydraulic oil pushes the piston 2 to move inside the cylinder body 1. One end of the piston 2 is connected to the piston rod 3, so the movement of the piston 2 will synchronously drive the movement of the piston rod 3. By rotating the handle 13, the threaded rod 11 can be rotated inside the circular tube 8. Since the outer ring surface of the threaded rod 11 is threadedly connected to the inside of the circular tube 8, rotating the handle 13 can move the threaded rod 11 along the circular tube 8. The limiting arc block 12 is used to tighten or loosen the piston rod 3. The inner wall of the limiting arc block 12 is provided with an anti-slip pad 14. The anti-slip pad 14 increases the friction between the limiting arc block 12 and the piston rod 3, preventing the piston rod 3 from sliding between the two limiting arc blocks 12 during movement, which would affect the stability of the support rod 10. When the piston rod 3 moves synchronously with the support rod 10, the support rod 10 will slide inside the limiting tube 7 and the first connecting block 5, thereby maintaining relative stability with the cylinder body 1 and the piston rod 3. By rotating the limiting ring 15, it can be installed at one end of the support rod 10, thereby preventing the support rod 10 from detaching from the limiting tube 7 and the first connecting block 5. The reinforcing rib 16 not only enhances the structural strength of the fixed arc plate 6, but also improves the connection stability between the limiting tube 7 and the fixed arc plate 6. The double support enables the cylinder piston rod to maintain stability when subjected to a large load.
