The background of the present invention relates to hydraulic piping and hose color stopper structures.

Hydraulic systems are widely used in various industries, and hydraulic piping and hoses are important components of these hydraulic systems.

They serve to effectively transmit high-pressure fluids and keep them safe within the system.

However, existing hydraulic pipe and hose stoppers had various problems.

First, it was difficult to clearly distinguish the connection between the hydraulic pipe and the hydraulic hose.

Therefore, users may experience confusion in attaching or removing the stopper in the correct position.

Additionally, it was difficult to check the locking and unlocking status of the stopper, and detection of oil discharge and leakage was limited.

In addition, the stopper did not have a one-way locking mechanism that could only be fastened and released in a specific direction, and it lacked wear resistance and heat resistance.

As a result, the stopper was likely to wear out over time or be damaged by hot fluids.

Moreover, existing hydraulic pipes and hose stoppers did not have the ability to independently adjust the pressure of pipes and hoses.

Because of this, in situations where the pressure of the entire system had to be adjusted, users had to install a separate pressure control device or go through complicated procedures.

To solve these problems, the present invention proposes an improved hydraulic piping and hose color stopper structure.

This is expected to improve the stability and efficiency of the hydraulic system while also increasing user convenience.

The present invention was devised to solve the above problems, and the object of the present invention is to provide a first stopper fastened to one side of a color-differentiable hydraulic pipe and a second stopper fastened to one side of a hydraulic hose.
