Description

[Technical field]

[0001] The utility model mainly relates to an oil cylinder fixing structure of a buffer hanging wheel. [Background technology]

[0002] The main reason for fixing the oil cylinder in the sliding door buffer is to ensure the stability and safety of the buffer during use. As the core component of the buffer, whether the oil cylinder is fixed or not is directly related to the working effect and service life of the buffer.

[0003] First, fixing the cylinder ensures the accurate positioning of the buffer during movement. In a sliding door buffer, the cylinder is usually connected to a slider or other moving parts, and the sliding door is buffered by controlling the extension and contraction of the cylinder. If the cylinder is not fixed, the cylinder may move due to inertia during the movement of the sliding door, resulting in poor buffering effect, and even possible damage to the sliding door or the buffer itself.

[0004] Secondly, fixing the oil cylinder can improve the durability of the buffer. During use, the oil cylinder will bear the impact force from the sliding door. If the oil cylinder is not fixed, it may vibrate violently when it is impacted, which will accelerate its wear and aging. Fixing the oil cylinder can effectively reduce vibration and extend the service life of the oil cylinder.

[0005] Therefore, it is very necessary to fix the oil cylinder in the sliding door buffer. In view of this, we propose an oil cylinder fixing structure for a buffer hanging wheel. [Contents of the utility model]
