[0002] The push -and -pull door is a kind of door commonly used in family, it refers to the door that can be pushed and pulled. Pulley is the most important hardware component in push -and -pull door, and the material of pulley on the market has three kinds of plastic pulley, metal pulley and glass fiber pulley. Metal pulley is strong, but it is easy to produce noise when contacting with track. Carbon glass fiber pulley contains roller bearing, and it is smooth, wear-resistant and durable, and box-type closed structure effectively prevents dust, and it is more suitable for the northern region with strong wind and sand, and two anti-jumping devices ensure safety and reliability when sliding.

[0003] The sealing method of the existing upper slide rail of lift push -and -pull door usually adopts frame body to design as a whole, and uses rubber strip as sealing material between frame and fan profile. But due to the displacement downward when the door fan is closed, the sealing rubber strip is overlapped on the back of track, so that the sealing is formed between frame and fan. The door fan needs to pass through the track from the front during installation, in order to avoid excessive friction between rubber strip and track during installation process, the overlapping amount of through rubber strip is designed to be very small, which leads to poor sealing when the door fan is closed.

[0004] Based on this, a high air tightness lift push -and -pull door upper slide rail is provided, which can eliminate the disadvantages of the existing device. UTILITY MODEL CONTENTS
