Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1.

A pin shaft fixing mechanism for an emergency double-door full-open door comprises a wall surface mounting plate 1, wherein a transition plate 2 is vertically connected with the wall surface mounting plate 1, a lower baffle plate 3 is mounted at the lower part of the transition plate 2, an elastic part 12 is arranged at the position, which is opposite to a pin shaft, of the transition plate 2 if necessary so as to automatically push out the pin shaft when the pin shaft is unlocked, a pivot mounting plate 4 is vertically connected with the outer side edge of the transition plate 2 backwards, a door suction mounting plate 11 can be connected with the pivot mounting plate 4 if necessary, a pin shaft hook plate 5 is pivoted on the pivot mounting plate 4, an inclined guide edge 10 is arranged on the front end surface of the pin shaft hook plate 5 so that the pin shaft can lift the pin shaft hook plate 5 through the guide edge 10 when the door head is locked, the pin shaft is convenient to slide into an open slot 6, which is adjacent to the guide edge and is arranged at the outer end of the pin shaft hook plate 5 and used for the pin shaft, one end of the unlocking plate 7 is connected with the lower end of the tension spring 8, the upper end of the tension spring 8 is connected with the tension spring fixing plate 9, the tension spring fixing plate 9 is connected with the mounting plate 4, during specific implementation, the lower end of the tension spring 8 can be connected with the unlocking plate 7 or directly connected with the pin shaft hook plate 5, and the unlocking plate 7 is connected with the unlocking plate 7 in the embodiment, as shown in fig. 1. The tension spring 8 enables one end of the pin shaft hook plate 5 with the opening groove 6 to be always supported on the lower baffle 3, so that the pin shaft hook plate 5 cannot be separated from the pin shaft, the unlocking plate 7 is subjected to upward acting force to overcome the tension force of the tension spring, the pin shaft hook plate 5 is driven to rotate upwards, and the pin shaft is separated from the pin shaft fixing mechanism by the constraint of the pin shaft hook plate 5.

During specific implementation, the wall surface mounting plate 1, the transition plate 2 and the pivot mounting plate 4 can be of a whole plate bending structure or a split type welding structure. The lower baffle 3 is welded with the transition plate 2, and the outer end of the lower baffle can also be provided with a downward inclined plane structure which forms a horn mouth together with the guide edge 10 of the front end surface of the pin shaft hook plate 5, thus being beneficial to the entering of the pin shaft.

The utility model discloses only need push the locating pin axle that sets up on the door head hard during the use, lift on the round pin axle hook plate 5 with the pulling force that the extension spring 8 was overcome to round pin axle contact direction limit 10, after round pin axle entering open slot 6, the outer end whereabouts of round pin axle hook plate 5 will sell the axle spacing between open slot 6 and lower baffle 3, and the round pin axle can't deviate from outwards. When an emergency state occurs, a pen or a similar rod-shaped object is inserted from an opening at the lower part of the head door to abut against the unlocking plate 7 to exert force upwards, the acting force of the tension spring is overcome, the pin shaft hook plate 5 is separated from the pin shaft (if the transition plate 2 is provided with the elastic part 12, the elastic part further pushes the pin shaft to move outwards to separate from the restraint), the restraint is released, and the whole door head can be pulled outwards. When necessary, a mechanism (such as a torsion spring) which can make the door head generate constant torque is arranged on the mounting shaft of the door head, so that the pin shaft can be automatically ejected after the restriction is released.

The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
