Technical field
The utility model belongs to the security protection facility field in the building operations, specifically, relates to a kind of automatic closed safe door of downside rotation type electro that the capital construction process is used for containment building elevator opening part or other opening parts that is used for.
Background technology
In house capital construction work progress, according to " the construction safety check criteria " of Ministry of Construction's promulgation, elevator opening part or other opening parts belong to the safety assurance project in the building.Therefore, unit in charge of construction all can be in building elevator opening part or other opening parts be provided with safeguard procedures.
In the existing work progress, most of unit in charge of construction adopts the discarded steel pipe on the building site or adopts staggered fixing back such as scaffold to form protective guard.Yet, still there are a lot of gaps in the protective guard that adopts this kind mode to form between the first protective guard, lack of standardization and still have a potential safety hazard, it two is to utilize this perforate to carry out some when operation if need to open protective guard midway in construction, and it is cumbersome to remove protective guard.
Also some unit in charge of construction adopts the safety protective door of horizontally openable to seal the effect that opening plays protection.Yet, all be to finish owing to be used for the opening and closing of the safety protective door of above-mentioned occasion at present by the conscious behavior of building operation and with manual mode, therefore in the use of reality, exist the mouth that opens the door to forget the situation of closing the door.Because of safety protective door forgets that closing the security incident that causes happens occasionally after opening.
The utility model content
Technical problem to be solved in the utility model provides the automatic closed safe door of a kind of downside rotation type electro, and the automatic closed safe door of this downside rotation type electro can utilize the gravity closing opening of door itself, plays the effect of security protection.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The automatic closed safe door of downside rotation type electro comprises the securing member, safety door body, the door bolt that are fixed in the opening both sides, has the door bolt perforate on the described securing member, and door bolt passes the door bolt perforate and fixedlys connected with the safety door body respectively.
Described securing member is an angle steel, and angle steel is fixed in the opening both sides by setscrew on one side, and the door bolt perforate is positioned on the angle steel another side; The axis of the door bolt perforate on the securing member of described opening both sides coincides.
Also be provided with the door lock that is used for fixing the safety door body position on the described securing member.
Also comprise keeper, also have two blocks of steel plates that be arranged in parallel on the described securing member, corresponding position is equipped with the keeper perforate on two block plates, and keeper passes the keeper perforate and the position of keeper between two keeper perforates has the block that radially protrudes with keeper external surface formation.
Described keeper and door bolt be arranged in parallel.
The axis of the keeper perforate on the securing member of described opening both sides coincides.
The hollow, rectangular framework that described safety door body is made of steel plate, laterally or be vertically fixed on the reinforcing bar between the rectangular frame and the expanded metal lath that is fixed in the rectangular frame constitutes.
In sum, the beneficial effects of the utility model are:
(1) safety door body of the present utility model is sagging with sealed open under the action of gravity of door body itself, and the mouth of can avoiding opening the door is forgotten the potential safety hazard of closing the door and causing.
(2) carrying out some when operation when construction needs to utilize this perforate midway, is that axis of rotation is rotated and turns over the safety door body with the door bolt place straight line of opening both sides, can expose the opening that a body blocks, midway easy construction.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Extremely shown in Figure 4 referring to Fig. 1, the automatic closed safe door of the downside rotation type electro of present embodiment comprises the securing member 2 that is fixed in opening 11 both sides, the door bolt 3 of safety door body 1,16 long 150mm, wherein, the opening both sides are the capital construction body of wall, the securing member 2 of opening both sides is an angle steel, angle steel is fixed on the body of wall of opening 11 both sides by 10 * 60 setscrews 4 on one side, has the door bolt perforate on the angle steel another side, door bolt 3 passes the door bolt perforate and fixedlys connected with safety door body 1 respectively, and the axis of the door bolt perforate on the securing member 2 of described opening 11 both sides coincides.Present embodiment fixedly connected can adopt welding or other fixed forms fixedly connected.
The hollow, rectangular framework that the safety door body is made of steel plate, vertical (vertical direction) are fixed in 12 reinforcing bars between the rectangular frame and are fixed in 25 interior expanded metal laths of rectangular frame and constitute, wherein, it is the steel sheet of L25 * 3mm that hollow, rectangular frame upper side, left side, right side adopt specification, and it is that the steel sheet of 200mm is as foot guard plate that downside adopts width.Safety door body width slightly is wider than A/F, can complete closed or block opening, door bolt 3 is for being the reinforcing bar of cylindrical shape, therefore can rotate around the door bolt perforate, 1 of safety door body is sagging with sealed open under the action of gravity of door body itself, carrying out some when operation when construction needs to utilize this perforate midway, is that axis of rotation is rotated and turns over safety door body 1 with the door bolt place straight line of opening both sides, can expose the opening that a body blocks.
