The heavy airtight door is an airtight door with a door body with larger weight, the weight of the door body of the airtight door is generally more than one hundred and fifty kilograms, the larger the weight of the door body of the airtight door is, the larger the pressure on the vacuum airtight rubber strip when the door body sinks, and the better the sealing effect is.
As shown in fig. 1 to 5, the existing airtight door includes a power beam 1, a door body 2 and two hangers 4, the internal installation of the power beam 1 has a slide rail 3 and a driving device 5, each hanger 4 has a roller 401 and a mounting rack 402, the mounting rack 402 is fixedly mounted on the door body 2, each roller 401 is disposed on the slide rail 3 and can roll, the driving device 5 drives the two hangers 4, and then drives the two rollers 401 to move horizontally along the slide rail 3, and then drives the door body 2 to move horizontally, when the two rollers 401 all move to the slide rail 3 and correspond to the two lower sinking grooves 301 that are disposed, the rollers 401 and the door body 2 sink, thereby realizing the closing of the door body 2. When the air-tight door needs to be opened, because the two rollers 401 are located inside the two corresponding sunken grooves 301, the driving device 5 must output a larger driving force to bring the two rollers 401 from the two sunken grooves 301 to the horizontal plane of the slide rail 3, and then the door 2 is completely opened, at this time, an auxiliary guide rail 7 and a small guide wheel 6 are generally added, the auxiliary guide rail 7 is arranged at the position of one of the sunken grooves 301 of the slide rail 3, the small guide wheel 6 is coaxially arranged with one of the rollers 401, and the small guide wheel 6 is arranged on the auxiliary guide rail 7, because the small guide wheel 6 can synchronously rotate along with the rollers 401, and the auxiliary guide rail 7 has a supporting function on the small guide wheel 6, the driving device 5 drives the rollers 401 to rotate, and then drives the small guide wheel 6 to rotate, the small guide wheel 6 further horizontally moves on the auxiliary guide rail 7, and then the two rollers 401 are brought from the two sunken grooves 301 to the horizontal plane of the slide rail 3 through the small guide wheel 6, the driving force of the driving device 5 does not need to be increased.
Although it is possible to remove the two rollers 401 from the corresponding two sunken grooves 301 without increasing the driving force of the driving device 5 by adding the auxiliary rail 7 and the small guide wheel 6, the installation cavity 101 inside the power beam 1 is small, additional installation space needs to be left by adding the auxiliary rail 7 and the small guide wheel 6, the volume of the power beam 1 is increased, and it is inconvenient to install or maintain.
In addition, only the roller on the horizontal plane of the sliding rail can provide support for the door body, and each hanger 4 is provided with only one roller 401, so that the load borne by the hanger 4 is small, and meanwhile, the small guide wheel 6 cannot bear large load, so that the weight of the door body 2 borne by the airtight door does not exceed one hundred and fifty kilograms generally, and the requirement of the heavy airtight door cannot be met.
