Overlapping door is mainly by doorframe beam mechanism, middle door leaf mechanism, door leaf mechanism and drive system are formed its structure such as Fig. 1 and Fig. 2 down.Doorframe beam mechanism is arranged at the top of whole overlapping door, is made up of doorframe beam and the auxiliary door leaf of doorframe beam.Centre door leaf mechanism is arranged at the centre of whole overlapping door, is made up of middle door leaf, middle door leaf guide rail and middle door leaf slide block mechanism.Following door leaf mechanism is arranged at the bottom of whole overlapping door, by door leaf and following door leaf slide block mechanism are formed down.Wherein, the upper limb outside of door leaf and following door leaf in the middle of the slide block mechanism between auxiliary door leaf of doorframe beam and the middle door leaf and the slide block of the slide block mechanism between middle door leaf and the following door leaf are arranged at respectively, the track of slide block mechanism is separately positioned on auxiliary door leaf of doorframe beam and the middle door leaf.Overlapping door is in running, and the pulley (mechanism) on middle door leaf (pulley mechanism) and the following door leaf moves in auxiliary door leaf guide rail of the doorframe beam of one deck and the middle door leaf guide rail respectively thereon.When middle door leaf and following door leaf upwards move, middle door leaf pulley (mechanism) and following door leaf pulley (mechanism) are all along with middle door leaf and the upwards operation of following door leaf, when being in opening, middle door leaf pulley (mechanism) and following door leaf pulley (mechanism) just mediate outside the upper limb of door leaf and following door leaf.Be subjected under the situation of positive blast, middle door leaf and the turning-in of following door leaf vertical direction, form certain amount of deflection, this state is equal to cantilever position, (not possessing) wind resistance is poor, and door leaf operation (poor stability) can be run into the inside (stacked) door leaf when (as shown in the figure 1,2 and 3), gently then can scratch door leaf, influence the attractive in appearance of whole door body, heavy then can influence the operation (if door leaf surface has protrusion) at gate.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of wind resistance reach well door leaf operation () the overlapping door of good stability.

The purpose of this utility model is achieved in that a kind of overlapping door, comprise doorframe beam mechanism, middle door leaf mechanism and following door leaf mechanism, described doorframe beam mechanism comprises doorframe beam and the auxiliary door leaf of doorframe beam, door leaf and middle door leaf guide rail in the middle of centre door leaf mechanism comprises, following door leaf mechanism comprises door leaf and following door leaf guide rail down, is characterized in:

The auxiliary door leaf lower edge inboard of described doorframe beam is provided with the auxiliary door leaf of doorframe beam and slides or rolling mechanism, and auxiliary door leaf slip of this doorframe beam or rolling mechanism slide or roll with described middle door leaf guide rail and cooperate;

Door leaf slided or rolling mechanism in the middle of door leaf lower edge inboard was provided with in the middle of described, and this centre door leaf pulley mechanism slides or rolls with described door leaf guide rail down and cooperates.

The utility model makes overlapping door being subjected under the blast situation by changing the installation site of door leaf slip or rolling mechanism, and is stable, and safe and reliable.

(5) specific embodiment

Referring to Fig. 4～5, Fig. 4 is the overlapping door of a utility model elevation, and Fig. 5 is the left side view of Fig. 4.By Fig. 4 and Fig. 5 as can be seen, the overlapping door of the utility model is mainly by doorframe beam mechanism 1, middle door leaf mechanism 2, door leaf mechanism 3 and drive system 4 are formed down.

Described doorframe beam mechanism 1 is arranged at the top of whole overlapping door, is made up of doorframe beam 1.1, the auxiliary door leaf 1.2 of doorframe beam and the auxiliary door leaf pulley mechanism 1.3 of doorframe beam.Described doorframe beam 1.1 transverse horizontal arrange that the auxiliary door leaf 1.2 of doorframe beam vertically is connected doorframe beam 1.1 belows downwards, and the auxiliary door leaf pulley mechanism 1.3 of doorframe beam is arranged at the auxiliary door leaf 1.2 lower edge inboards of described doorframe beam;

Door leaf mechanism 2 is arranged at the centre of whole overlapping door in the middle of described, is made up of middle door leaf 2.1, middle door leaf guide rail 2.2 and middle door leaf pulley mechanism 2.3.Door leaf guide rail 2.2 has many in the middle of described, door leaf guide rail 2.2 vertically is arranged in described doorframe beam mechanism 1 below downwards at interval in the middle of many, and cooperate with auxiliary door leaf pulley mechanism 1.3 (cunning) rolling of the doorframe beam of described doorframe beam mechanism, between the door leaf guide rail 2.2, described middle door leaf pulley mechanism 2.3 was arranged at described middle door leaf 2.1 lower edge inboards in the middle of door leaf 2.1 was slidingly connected to described adjacent two in the middle of described;

Described door leaf mechanism 3 down is arranged at the bottom of whole overlapping door, by door leaf 3.1 and following door leaf guide rail 3.2 are formed down.Described door leaf guide rail 3.2 down has many, many following door leaf guide rails 3.2 vertically be arranged at interval downwards described in the middle of door leaf mechanism 2 belows, and with described in the middle of middle the door leaf pulley mechanism 2.3 of door leaf mechanism be slidingly matched, described time door leaf 3.1 is slidingly connected between described adjacent twice door leaf guide rails 3.2;

Overlapping door is when operation, the following door leaf guide rail 3.2 of following door leaf mechanism 3 is along the upwards operation of middle door leaf pulley mechanism 2.3 of middle door leaf mechanism 2, the inner surface of door leaf 2.1 in the middle of running into simultaneously, door leaf 2.1 in the middle of driving, and the operation on the auxiliary door leaf pulley mechanism 1.3 of the doorframe beam of doorframe beam mechanism 1 of the middle door leaf guide rail 2.2 of middle door leaf mechanism, as shown in Figure 6 and Figure 7.And assist the lower edge inboard of the middle door leaf 2.1 of door leaf 1.2 and middle door leaf mechanism at the doorframe beam that middle the door leaf pulley mechanism 2.3 of auxiliary door leaf pulley mechanism 1.3 of the doorframe beam of the beam of doorframe described in running mechanism and middle door leaf mechanism is in described doorframe beam mechanism all the time respectively, as Fig. 8, therefore the stability and the wind loading rating of whole overlapping door under opening have been guaranteed, as Fig. 9.
