Abstract

The invention relates to a hot air isolated door locking mechanism, in particular to a mechanism used for locking and sealing of a door plate of an isolated door and a door frame of the isolated door, and belongs to the technical field of isolated doors. The hot air isolated door locking mechanism comprises a first connecting lever seat and a second connecting lever seat, the first connecting lever seat is connected with two first connecting levers through a pin shaft, the second connecting lever seat is connected with two second connecting levers through a pin shaft, one end of the first connecting lever seat is connected with a first connecting rod, one end of the second connecting lever seat is connected with a second connecting rod, and the first connecting rod and the second connecting rod are connected through adjusting screw rods. The hot air isolated door locking mechanism is exquisite, compact and reasonable in structure and capable of adjusting the relative positions of a door plate and a door frame, improves sealing performance between the door plate and the door frame, and improves the safety of examination staff, and the door plate is flexible and reliable to open.

Description

technical field [0001] The invention relates to a locking mechanism for a hot air isolation door, specifically a mechanism for locking and sealing a door panel and a door frame of an isolation door, and belongs to the technical field of isolation doors. Background technique [0002] With the rapid development of thermal power units, coal mills, as the main pulverizing equipment in large thermal power plants, have also been developed accordingly. Coal mills have the advantages of low investment, low power consumption, and easy operation, but they also have disadvantages such as easy wear and long maintenance time. Since the pulverization capacity of the coal mill is directly related to the output of the generating set, the quality of the coal mill directly affects the normal operation of the entire power plant. [0003] As the main isolation equipment for the coal mill and boiler system, the isolation door is the most important in the system. When the coal mill is put into ...
