Problems solved by technology

In the past, the output shaft needs to be directly connected to the reversing transmission, and it is introduced into the door leaf from the inner surface of the door leaf. It will not be affected in normal use, but when the bushing and the output shaft are damaged or need maintenance, all the above-mentioned devices need to be taken out. , before the replacement or maintenance of the casing and the output shaft can be carried out. This process is time-consuming and laborious, and it is extremely inconvenient.

Abstract

The invention relates to an improved civil defense door leaf sealing beam sleeve pipe and an extension shaft structure. A sealing beam sleeve pipe disposed in a door leaf, and the extension shaft is disposed in the sealing beam sleeve pipe, and the extension shaft is smoothly connected with the sealing beam sleeve pipe. One end of the outer part of the door leaf of the extension shaft is connectedwith a connection block, and one end of the inner part of the door leaf of the extension shaft is connected with a reversing transmission. According to the invention, replacement and maintenance areconvenient, and time and labor can be saved.

Description

technical field [0001] The invention relates to a connecting structure, in particular to a sealing beam sleeve and connecting shaft structure of a civil air defense door leaf. Background technique [0002] GWSFM type subway civil air defense door is used in the entrance and exit of subway projects. There is no threshold at the bottom at ordinary times, which is convenient for vehicles to pass. . In the past, the output shaft needs to be directly connected to the reversing transmission, and it is introduced into the door leaf from the inner surface of the door leaf. It will not be affected in normal use, but when the bushing and the output shaft are damaged or need maintenance, the entire set of above-mentioned devices must be taken out , before the replacement or maintenance of the casing and the output shaft can be carried out. This process is time-consuming and laborious, and is extremely inconvenient. Contents of the invention [0003] Purpose of the invention: The pu...
