[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rigid tracks perpendicular to the horizontal plane or with an angle of inclination less than 15° to the plumb line. There are also step-type ones, with the treads mounted on the tracks and running continuously, commonly known as escalators or moving walkways. When manufacturing elevator parts, they need to be powder-sprayed in a powder spraying room.

[0003] China Patent Network CN116116638A discloses a sealing structure and an elevator accessory powder spraying room, comprising: a long groove and a circular groove are provided on the surface of a connecting plate, and a sealing plate is provided on the inner wall of a powder spraying room body; a locking plate is provided inside the mounting groove, and a threaded hole and a control groove are provided on the surface of the locking plate; a door is provided on the side of the powder spraying room body, a convex plate is provided on the surface of the door, a sealing gasket groove is provided on the surface of the convex plate, a sealing gasket is provided inside the sealing gasket groove, a connecting rod is provided on one side of the door, a rotating shaft is provided inside the connecting rod, and a flat shaft is provided at the end of the rotating shaft; the beneficial effect is that when the flat shaft is located inside the circular groove, the door is controlled to rotate, and when the door is parallel to the surface of the powder spraying room body, the door is pushed toward the powder spraying room body, so that the flat shaft enters the inside of the long groove, and the door is tightened on the surface of the powder spraying room body by controlling the locking plate to squeeze the sealing gasket, thereby achieving sealing.

[0004] However, in the above technical solution, when the powder spraying room body is sealed, the powder spraying room body is simply sealed by relying on the door cover in cooperation with the sealing gasket. The sealing is relatively simple. Because the powder is relatively fine, long-term use may lead to incomplete sealing effect of the door cover, so that the powder may float out. Therefore, the utility model proposes a cover with a multiple sealing structure to solve the above-mentioned technical problems. Utility Model Content
