[0002] Public row chairs, as the name implies, are chairs used in public places. They are generally designed as one-piece and placed in rows. They are practical and easy to clean. There are roughly two forms of public seats, namely benches and chairs. The setting of public seats brings many conveniences to pedestrians. When people are tired or uncomfortable, they can provide convenience for people in time. Therefore, the setting of public seats in public environments is of great significance. There are at least the following disadvantages in the use of existing public seats:

[0003] 1. The existing public seats cannot be easily adjusted in height during use, and cannot provide a suitable seat height to serve different people.

[0004] 2. During the use of existing public seats, since the seats are exposed to the outdoors for a long time, wind and sun cause dust pollution and rain erosion, which affects the service life of the seats. The surface of the seats is dirty, making it inconvenient for people to sit down, affecting the public service of the seats. Therefore, we have launched a public seat with dust and rainproof functions. Utility Model Content
