Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of iron gate of the present utility model under in off position.

Fig. 2 is the structural representation of iron gate of the present utility model under opening-wide state.

The specific embodiment

I have specifically made a sample according to above-mentioned design scheme, know that for describing the present will remove door skin and expose the door of internal construction, narrate its structure and operating advantage according to closed condition and opening-wide state respectively.Because of the most and common iron gate of the important composition of iron gate of the present utility model is identical,, the invention main points is then given carefully state so only do simple narration.

Iron gate of the present utility model as shown in Figure 1, it comprise gate doorframe 1, two 2,3, sub-door leafs 4 of door leaf and hinge 55 '; It is inboard and corresponding with the dead bolt nest 24 that is contained in door leaf 2 inboards that the door lock 41 of this iron gate is contained in cervical orifice of uterus fan 4, and operation easily.Level to latch 21 be fixed on door leaf 2 on guiding pin bushing 22 and 22 ' become to be slidingly matched, and this latch middle part is equipped with and can be touched the spacing handgrip 211 of resistance with two pin bushings mutually; Because latch 21 front end wedgewises, so very easy insertion be provided with upper and lower latch 23 and 23 in the door leaf 2 ' the gap and be located at upper and lower latch 33 and 33 in the door leaf 3 ' the gap, and make two groups of upper and lower latches insert the top rail pin hole and the lower transverse beam pin hole of gate doorframe 1 respectively, and door leaf 2 and 3 is connected on the doorframe 1 firmly by the component effect on inclined-plane.When opening the door, consult Fig. 2, the lock 41 that then opens the door is earlier opened cervical orifice of uterus 4 and handgrip 211 Zolas is made level to latch 21 and two groups of upper and lower latches 23,23 ' and 33,33 ' disengagement again, make latch 23,33 borrow the deadweight tenesmus to break away from the last jack of doorframe top rail, and down latch 23 ', 33 ' under the effect of spring 25,35, rise, and by be located at respectively limiting block head 231,331 and 231 on the upper and lower latch ', 331 ' effect, make two groups of upper and lower latches be parked in the appropriate location separately.

Its gate of iron gate of the present utility model and cervical orifice of uterus be only with same lock locking, only formerly the vertical latch of horizontal latch and interlock with it plugged together and just can lock cervical orifice of uterus and gate afterwards; After also only opening cervical orifice of uterus with key in the ban, just can unplug horizontal latch with vertical latch and open the gate.This door has simple in structure, and low price is convenient to operate and safe and reliable advantage, should make to reach between peasant household's storehouse, workshop, raising the gate on the courtyard enclosure wall especially.

In the above-described embodiments, because of limited by machining accuracy, inclined-plane on the horizontal latch and horizontal plane width are narrow slightly, and on, sagging straight pin end face is less, easily produce off normal between horizontal latch and two the vertical latches and operate malfunctioning, can two vertical on the lower end of latch and two following latches on plane bigger of termination than latch cross section, and on described, on the door leaf framework at the position, gap of following latch affixed one with last, following latch touch mutually positive stop, this mode is simple in structure, but can prevent from effectively to operate malfunctioning, the resistance when reducing the horizontal latch of pulling.
