SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a high reliability electromagnetism comes and goes formula people's air defense door through setting up locking mechanism, realizes opening the door, can pin the rocking arm axle when closing the door, improves its security.
The purpose of the utility model is realized like this: the utility model provides a high reliability electromagnetism comes and goes formula people's air defense door, includes the door body, installs the rocking arm axle on the door body, and the transmission is connected with the lockpin on the rocking arm axle, the tip fixedly connected with rocking arm of rocking arm axle, the internal electromagnetism comes and goes formula locking mechanism that is provided with of door, electromagnetism comes and goes formula locking mechanism includes gyration dish, bearing frame, electro-magnet and locking push rod, the fixed suit of gyration dish is in the periphery of rocking arm axle, the periphery of gyration dish is seted up and the slot, bearing frame and electro-magnet are all fixed on the internal wall of door, the bearing frame sets up between gyration dish and electro-magnet, and the flexible end of electro-magnet links to each other with the locking push rod, the locking push rod runs.
The utility model discloses the during operation, when the door body is in the closed condition, the locking push rod is inserted and is pinned the gyration dish in the slot, avoids its rotation to pin the lockpin, when needs are opened, control electromagnetic lock work, the electromagnetic lock is got the electricity, with the withdrawal of locking push rod, the artifical rocking arm that rotates drives the gyration dish and rotates, the lockpin of withdrawal simultaneously can be opened the door. Compared with the prior art, the beneficial effects of the utility model reside in that, the utility model discloses an use electromagnetism to come and go formula locking mechanism pins the rocking arm axle, eliminates the potential safety hazard, has improved the security that people's air defense door used greatly. The utility model discloses can be used to in the people's air defense construction.
In order to make the utility model discloses use more in a flexible way, locking mechanism periphery cover is equipped with reset spring, locking push rod middle part processing has the flange, reset spring's one end is contradicted on the flange, and the other end is contradicted in the bearing frame. After the rocker shaft is reset, the locking push rod is automatically inserted into the slot under the action of the reset spring to complete locking, and when unlocking is needed, the locking push rod can be retracted only by controlling the electromagnet to work.
In order to enable the locking push rod and the electromagnet to be more conveniently assembled, the locking push rod is hinged with the telescopic end of the electromagnet.
In order to enable the locking push rod to be more conveniently inserted into the slot, a pair of inclined planes are processed at one end, close to the rotary disc, of the locking push rod, and the slot is processed into a structure matched with the end part of the locking push rod.
In order to realize locking when making the civil air defense door open and close, two slots are provided, and the phase angle of two slots is 90 degrees.
