The connecting plate is arranged on the front of the door frame, and the back of the connecting plate is fixedly connected to the output end of the cylinder, and the cylinder is fixedly connected to the door frame. In the utility model, when the two steel doors approach each other, the two buffer plates first contact, and after the two buffer plates contact, the steel door continues to move toward the buffer plate, so as to be buffered under the elastic force of the spring, thereby improving the protection of the steel door and extending the service life of the steel door.

[0004] Most of the existing technical solutions have the following defects: when the steel door body is closed, the gap at the connection is large, and the limiting and guiding effect is poor, which makes it easy for the steel door body to derail during movement, thus shortening the service life of the steel door body. Therefore, the utility model provides a new type of clamp-type steel door to solve the above-mentioned problems. Utility Model Content
