Specific embodiments

[0025] The above solutions will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrative purposes only and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0026] Embodiment 1: Please refer to Figures 1 - 5 , a new type of piston rod, comprising: a piston rod body 1, a mounting rod I 2 and a mounting rod II 3, the mounting rod I 2 and the mounting rod II 3 are respectively connected to the upper and lower ends of the piston rod body 1 by threads; a sealing ring 4, the sealing ring 4 is sleeved on the mounting rod II 3; to ensure the sealing between the piston rod body 1 and the cylinder and prevent leakage; a buffer pad 20, the buffer pad 20 is arranged at one end of the piston rod body 1 close to the mounting rod I 2 to reduce the impact and vibration generated during the movement of the piston rod; further comprising: a docking rod I 5, the docking rod I 5 is connected to the mounting rod II 3 by threads, and a plurality of clamping holes 6 distributed along the circumference are arranged on the inner wall of the docking rod I 5, a clamping ball 7, the clamping ball 7 is installed in the clamping hole 6; a sliding ring 8, the sliding ring 8 is slidably installed outside the docking rod I 5; a return spring 9, the return spring 9 is sleeved outside the docking rod I 5, and its two ends are respectively connected to the sliding ring 8 and the docking rod I 5; a docking rod II 10, the docking rod II 10 is connected to the mounting rod I 2 by threads, the docking rod II 10 can be clamped and fixed with the docking rod I 5 to realize the assembly function of the piston rod, and a clamping position groove 11 is arranged on the surface of the docking rod II 10, and through the cooperation of the clamping ball 7 and the clamping position groove 11, a firm connection between the docking rod I 5 and the docking rod II 10 is realized.

[0027] During use, first, use the mounting rod I 2 and the mounting rod II 3 to screw the docking rod II 10 and the docking rod I 5 into the upper and lower ends of the piston rod body 1 respectively to complete the basic assembly of the piston rod. Then, the above steps can be repeated to assemble multiple piston rods. Next, splice them by docking the docking rod II 10 with the docking rod I 5. Pull the sliding ring 8. At this time, the return spring 9 is compressed. Insert the docking rod II 10 of one piston rod into the docking rod I 5 of another piston rod and ensure that the locking ball 7 snaps into the locking groove 11. Then release the sliding ring 8. Under the restoring elastic force of the return spring 9, the sliding ring 8 returns to its original position and presses the locking ball 7 tightly, thus realizing the firm splicing of multiple piston rods. Continue splicing until the required total length is reached to meet the needs of different occasions. Finally, install the piston of the piston rod on the docking rod I 5 of the last section of the piston rod to complete the final installation of the piston rod system.

[0028] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 6 - 8 , and further includes: a connecting plate 12, which is assembled at one end of the piston rod body 1 close to the mounting rod I 2; a liquid cooling circulation tank 13, which is installed outside the connecting plate 12 and stores coolant inside; a circulation pipe 14, which is arranged inside the connecting plate 12, and the liquid inlet end of the circulation pipe 14 passes through the connecting plate 12 and is connected to the liquid cooling circulation tank 13. In addition, the circulation pipe 14 is arranged in a circular surrounding manner, so that a uniformly distributed coolant flow path can be formed around the piston rod body 1, making the coolant flow more uniformly on the surface of the piston rod body and improving the cooling effect.

[0029] When the piston rod body 1 operates, the coolant in the liquid cooling circulation tank 13 will enter the circulation pipe 14, and the coolant circulates in the circulation pipe 14 to cool the surface of the piston rod body 1, ensuring the stable operation of the piston rod body 1.

[0031] During use, open the sealing plug 19, inject lubricating oil into the one-way pipe 18. The lubricating oil enters the annular pipe 16 and flows out through the liquid outlet pipe 17, thereby wetting the two sponge rings 15. As the piston rod body 1 moves, the sponge rings 15 will evenly apply the lubricating oil on the surface of the piston rod body 1 to achieve the lubrication effect, thus reducing the friction between the cylinder wall and the piston and reducing the heat and wear generated therefrom.

Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
