Abstract
The utility model discloses a folding metal door which comprises a support, a first door plank, a second door plank, a third door plank and a door hasp, wherein the support is fixed on a wall, the first door plank is connected with the support in a rotary mode, the second door plank is connected with the first door plank in the rotary mode, the third door plank is connected with the second door plank in the rotary mode, and the door hasp is connected to the perpendicular outer side edge of the third door plank. The door hasp comprises a fastening part, a fixed part and a fastening base, wherein a fastening hole is formed in the fastening part, the fixed part is fixed on the perpendicular outer side edge of the third door plank, the fastening base is matched with the fastening part, the fixed part is connected with the fastening part through a hinged part, and an included angle of 40-65 degrees is formed between the hinged part and the perpendicular outer side edge of the third door plank. The folding metal door is simple in structure, due to the fact that the folding metal door is made of metal materials of high hardness, the folding metal door is capable of being opened and closed by 180 degrees, difficult to deform, firm, durable and capable of being prevented from being deformed seriously in the using process, and thus the service life of the folding metal door is prolonged.
Description
Technical field
The utility model relates to a kind of door, especially relates to a kind of collapsible metal door.
Background technology
General door is as a whole, and the one side is by adopting the fixing mode of hinge to be installed in a side of doorframe.There is following defective in the door of existing structure: at first, hinge can only 90 ° of foldings, if it is narrow and small that the position of door is installed, door can not be opened fully, are unfavorable for that the user uses; Secondly, hinge generally is to be made of stalloy and thin rotating shaft, its rigidity a little less than, after long-term the use distortion larger, easily produce the result of folding difficulty, cause the application life of door shorter.
The utility model content
Technical problem to be solved in the utility model is to propose a kind of simple in structure, not yielding and collapsible metal door that can 180 ° of foldings.
The utility model adopts following technical scheme to realize: a kind of collapsible metal door, it comprises: the first door-plate that is fixed on the bearing of wall, is rotatably connected with bearing, the second door-plate that is rotatably connected with the first door-plate, the 3rd door-plate that the second door-plate is rotatably connected, and the door hasp that is connected to the vertical outer limit of the 3rd door-plate; Wherein, the fixed part on the vertical outer limit that the door hasp comprises buckling parts with a fastening hole, be fixed on the 3rd door-plate and the fastening base that matches with buckling parts, fixed part links to each other with buckling parts by the articulated section, and has 40 °～65 ° angle between the vertical outer limit of articulated section and the 3rd door-plate.
Wherein, the first door-plate and the second door-plate are strip.
Wherein, the 3rd door-plate is rectangle.
Wherein, bearing is provided with semicircular pit, and the first door-plate is provided with the turning cylinder that stretches in the pit.
Wherein, the first door-plate is provided with the first key seat, and the second door-plate is provided with the second rotational pin that inserts in the first key seat.
Wherein, the second door-plate is provided with the second key seat, and the 3rd door-plate is provided with the 3rd rotational pin that inserts in the second key seat.
Compared with prior art, the utlity model has following beneficial effect:
The collapsible metal door that the utility model proposes simple in structure, the metal material that working strength is higher is made, can 180 ° of folding, not yielding, sturdy and durable, can prevent excessive deformation in use, thereby improve application life.

Fig. 2 is perspective view of the present utility model;
Fig. 3 is the structural representation of snap close.
The specific embodiment
In conjunction with illustrated in figures 1 and 2, the utility model proposes a kind of distortion-free collapsible metal door that can 180 ° of foldings, it comprises bearing 1, the first door-plate 2, the second door-plate 3 and the 3rd door-plate 4 that links to each other successively, and the door hasp 5 that is connected to the vertical outer limit of the 3rd door-plate 4.Wherein, bearing 1 is fixed on the wall, and the surface of this bearing 1 is provided with semicircular recess 11; The strip structure of the first door-plate 2 for being connected with bearing 1, the limit, wherein two opposite sides of the first door-plate 2 arranges respectively turning cylinder 21 and the first key seat 22, and turning cylinder 21 stretches in the pit 11 of this bearing 1; The second rotational pin 31 is set respectively on the limit, wherein two opposite sides of the second door-plate 3 and the second key seat 32, the second rotational pins 31 insert in the first key seat 22 of this first door-plate 2; A wherein side of the 3rd door-plate 4 arranges the 3rd rotational pin 41, the three rotational pins 41 and inserts in the second key seat 32 of the second door-plate 3.
In conjunction with shown in Figure 3, door hasp 5 comprises: the rotating buckling parts 51 with a fastening hole 50; Be fixed on the fixed part 53 on the vertical outer limit of the 3rd door-plate 4, this fixed part 53 links to each other with buckling parts 51 by articulated section 52, and has an angle between the vertical outer limit of articulated section 52 and the 3rd door-plate 4, and this angle is 40 °～65 °; Be fixed on the fastening base 54 that matches with buckling parts 51 on the wall.Owing between the vertical outer limit of articulated section 52 and the 3rd door-plate 4 angle being set, when buckling parts 51 rotates, under Action of Gravity Field, can turn to the external surface that is fitted in the 3rd door-plate 4, can not stretch out the vertical outer limit of the 3rd door-plate 4 and the situation that occurs easily hurting sb.'s feelings.
Bearing 1 is fixed on the body of wall, the first door-plate 2 is articulated in by turning cylinder 21 in the pit 11 of bearing 1 and rotates, 3 foundations of the second door-plate the second rotational pin 31 is articulated in the first key seat 22, thereby rotate relative to the first door-plate 2,4 foundations of the 3rd door-plate the 3rd rotational pin 41 is articulated in the second key seat 32 and rotates relative to the second door-plate 3.
To sum up, the utility model proposes can 180 ° of foldings distortion-free collapsible metal door not only can make collapsible metal door have the function of 180 ° of foldings, and can make collapsible metal door sturdy and durable, prevent in use excessive deformation, improve application life.
