Abstract | The invention discloses an air door auxiliary switch device.The device is mainly used for solving the problem that the kinetic energy of an air door destroys the air door and an air wall when the air door is closed, and collecting the kinetic energy when the air door is closed; the kinetic energy is released when the air door is opened at next time, so that the difficult to open the air door is reduced. By the device, when being closed, the air door strikes a sliding block, the sliding block compresses a spring behind the sliding block, the spring is compressed to gather energy; when the air door is closed completely, an automatic locking device on the sliding block is started to fix the sliding block; when the air door is opened, the locking device is relieved by a rod, the energy gathered by the spring is released and transferred to the air door by the sliding block, so that the opening difficult of the air door is reduced. The device satisfies the energy-saving and environment-protecting development requir |
