Description

Technical Field

[0001] This utility model relates to the field of gas spring technology, specifically a new type of corrosion-resistant powder-coated gas spring. Background Technology

[0002] A gas spring is an industrial component that provides support, cushioning, braking, height adjustment, and angle adjustment. It consists of the following parts: a pressure cylinder, piston rod, piston, sealing guide sleeve, filling material (inert gas or an oil-gas mixture), internal and external control elements (for controllable gas springs), and connectors. The principle is to fill the sealed pressure cylinder with inert gas or an oil-gas mixture, making the pressure inside the chamber several times or tens of times higher than atmospheric pressure. The piston rod's movement is achieved by utilizing the pressure difference created by the smaller cross-sectional area of ​​the piston rod compared to the piston's cross-sectional area. Due to this fundamental difference in principle, gas springs have significant advantages over ordinary springs: relatively slower speed, smaller dynamic force variation (generally within 1:1.2), and easier control.

[0003] The piston rod is the connecting component that supports the piston in performing work. It is mostly used in the moving parts of hydraulic cylinders and pneumatic cylinders, and is a moving component with frequent movement and high technical requirements. Taking a hydraulic cylinder as an example, it consists of several parts: cylinder barrel, piston rod (cylinder rod), piston, and end cap. The quality of its machining directly affects the lifespan and reliability of the entire product. The piston rod has high machining requirements; its surface roughness requirement is Ra0.4~0.8μm, and strict requirements are placed on coaxiality and wear resistance. The basic characteristic of the cylinder rod is that it is a slender shaft, which is difficult to machine and has always been a challenge for machining personnel.

[0004] Existing powder coating pneumatic piston rods still have the following drawbacks: they are usually made of metal materials, and long-term exposure to corrosive environments such as chemicals can easily lead to problems such as rust and corrosion, resulting in a decline in the performance of the piston rod or even failure, which affects the quality and efficiency of powder coating. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a novel corrosion-resistant powder coating pneumatic piston rod with a protective mechanism. This addresses the issue that powder coating pneumatic piston rods, typically made of metal, are prone to rusting and corrosion when exposed to corrosive chemical environments for extended periods. This corrosion leads to decreased performance or even failure of the piston rod, negatively impacting the quality and efficiency of powder coating.

[0007] The piston mechanism includes a piston rod, and the protective mechanism includes a storage tank, a valve, a delivery pipe, a sealing cylinder, a protective cylinder, fixing bolts, mounting bolts, a sealing ring, a threaded rod, a mounting ring, and a connecting rod. The storage tank is fixedly installed on the top of the base.

Fixing bolts are provided between the sealing cylinder and the piston rod for fixation, and mounting bolts are provided between the sealing cylinder and the protective cylinder for fixation.

[0008] Furthermore, screws are installed inside the base, and valves are installed inside the delivery pipe.

The mounting cylinder is fixedly installed on the top inner wall of the sleeve. One end of the second spring and one end of the telescopic rod are movably disposed inside the mounting cylinder. The bottom end of the telescopic rod is fixedly connected to the crash barrier.

[0011] Furthermore, the two ends of the upright are respectively connected to the upper and lower inner walls of the sleeve, the damping plug is fitted to the outside of the upright, the limiting plate is movably fitted to the outside of the upright and located below the damping plug, and the spring is movably fitted to the outside of the upright and located at the bottom of the limiting plate.

[0013] This utility model provides a novel corrosion-resistant powder-coated pneumatic mast through improvements, which has the following improvements and advantages compared with the prior art:

[0014] By incorporating a triple combination of an internal piston mechanism, an external protective mechanism, and an internal limiting mechanism, the sealing performance and reliability of the gas rod are effectively improved. The storage tank contains sealing oil. When the piston mechanism moves, the piston rod drives the sealing cylinder and protective cylinder to move, causing the internal space of the protective cylinder to change. This allows for variations in the volume of the sealing oil, which provides sealing protection to the outside of the piston mechanism's sleeve and also cools the piston mechanism, resulting in better performance and preventing corrosion damage to the sleeve's exterior. The sealing cylinder protects the piston rod, and the piston rod's exterior is covered with a corrosion-resistant layer, effectively preventing corrosive substances from eroding the piston rod surface. Furthermore, the combination of the sealing cylinder and protective cylinder further enhances the gas rod's airtightness, significantly improving the overall corrosion resistance of the piston mechanism.

[0021] The following will be combined with the appendix Figures 1 to 4 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model provides a novel corrosion-resistant powder-coated pneumatic mast through improvements, such as... Figure 1-4As shown in the figure, it includes a base 1, a piston mechanism is provided inside the base 1, a protective mechanism is provided outside the piston mechanism, and a limit mechanism is provided inside the piston mechanism.

[0023] The piston mechanism includes a piston rod 10, and the protective mechanism includes a storage tank 2, a valve 3, a delivery pipe 4, a sealing cylinder 20, a protective cylinder 24, a fixing bolt 15, a mounting bolt, a sealing ring 7, a threaded rod 12, a mounting ring 13, and a connecting rod 14. The storage tank 2 is fixedly installed on the top of the base 1. The top of the storage tank 2 is connected to one end of the delivery pipe 4, and the other end of the delivery pipe 4 is connected to the protective cylinder 24. The sealing cylinder 20 is threaded onto the outside of the top of the piston rod 10. The top of the threaded rod 12 is fixedly connected to the inner wall of the top of the sealing cylinder 20, and the threaded rod 12 is threaded into the inside of the piston rod 10. The top of the connecting rod 14 is fixedly connected to the mounting ring 13, and the bottom of the connecting rod 14 is fixedly connected to the sealing cylinder 20. The sealing cylinder 20 and the piston rod 10 are fixedly connected by fixing bolts 15, and the sealing cylinder 20 and the protective cylinder 24 are fixedly connected by mounting bolts. The system features a triple combination of a piston mechanism, an external protective mechanism, and an internal limiting mechanism, effectively improving the sealing performance and reliability of the gas rod. The storage tank 2 contains sealing oil. When the piston mechanism moves, the piston rod 10 moves the sealing cylinder 20 and the protective cylinder 24, causing the internal space of the protective cylinder 24 to change, thus varying the volume of the sealing oil. The sealing oil provides sealing protection to the outside of the sleeve 8 of the piston mechanism and also cools the piston mechanism, resulting in better performance and preventing corrosion damage to the outside of the sleeve 8. The sealing cylinder 20 seals and protects the piston rod 10, while the piston rod 10 has a corrosion-resistant layer 11 on its exterior, effectively preventing corrosive substances from eroding the surface of the piston rod 10. Furthermore, the combination of the sealing cylinder 20 and the protective cylinder 24 further enhances the airtightness of the gas rod, significantly improving the overall corrosion resistance of the piston mechanism.

[0024] The base 1 has screws inside, and the delivery pipe 4 has valve 3 inside. The sleeve 8 can be installed in a suitable position by the screws, and the valve 3 can control the flow of sealing oil.

[0025] The piston mechanism also includes a sleeve 8, a corrosion-resistant layer 11, and a damping plug 9. The sleeve 8 is fixedly installed inside the base 1. The bottom end of the piston rod 10 is fixedly connected to the damping plug 9. The damping plug 9 is slidably connected to the inner wall of the sleeve 8. The corrosion-resistant layer 11 is coated on the outside of the piston rod 10. By coating the outside of the piston rod 10 with the corrosion-resistant layer 11 and fixing the bottom end of the piston rod 10 to the damping plug 9, and by the damping plug 9 being slidably connected to the sleeve 8, the piston mechanism becomes more corrosion-resistant. At the same time, the damping plug 9 also plays a damping role, reducing the impact and vibration during piston movement, thereby making the performance of the piston mechanism more stable.

[0026] The limiting mechanism includes a sealing ring 16, a vertical rod 18, a first spring 5, a limiting plate 6, a crash barrier 19, a telescopic rod 23, a second spring 22, and a mounting cylinder 17. The mounting cylinder 17 is fixedly installed on the top inner wall of the sleeve 8. One end of the second spring 22 and the telescopic rod 23 are movably disposed inside the mounting cylinder 17. The bottom end of the telescopic rod 23 is fixedly connected to the crash barrier 19. The two ends of the vertical rod 18 are respectively connected to the upper and lower inner walls of the sleeve 8. The damping plug 9 is limited and sealed outside the vertical rod 18. The limiting plate 6 is movably sleeved outside the vertical plate and located below the damping plug 9. The first spring 5 is movably sleeved outside the vertical rod 18 and located at the bottom of the limiting plate 6. A sealing gasket 21 is movably sleeved above the connection between the piston rod 10 and the protective cylinder 24 and is located inside the sealing cylinder 20. A sealing ring 7 is provided at the bottom connection between the protective cylinder 24 and the sleeve 8 and is located inside the protective cylinder 24.

[0027] By cleverly combining devices such as the limiting plate 6, spring 5, telescopic rod 23, and anti-collision plate 19, the device effectively prevents overload or collision of mechanical parts while ensuring safe and stable mechanical operation. The device achieves its limit control function. The mounting cylinder 17 is fixedly installed on the top of the sleeve 8, and the spring and telescopic rod 23 move inside. The telescopic rod 23 is connected to the anti-collision plate 19 to limit the range of mechanical movement and prevent the damping plug 9 from having a hard collision with the top of the sleeve 8. The upright rod 18 connects the upper and lower parts of the sleeve 8. The limiting plate 6 and spring 5 are movably sleeved on the outside of the upright rod 18 to prevent the damping plug 9 from excessively displacing. The protective cylinder 24 is connected to the bottom of the sleeve 8 and equipped with a sealing ring 7 to ensure the sealing performance of the device and achieve a safe, stable, and reliable limit control effect.
