Description

The anti-direct insertion hinge of forcing open the door of row's fan

The utility model belongs to the Door for building hinge, installs and uses on being adapted at that metal is anti-and forcing open the door.

At present, various doors mostly adopt bright hinge (common name folding) in building construction, its structure is made up of the mutually folding metal loose-leaf of two fans, middle break-through rotating shaft, and wherein one page pivots and can reach corner more than 0～90 °, in two fan foldings, have many fixing holes, to use bolton on the doorframe and door leaf of building, advantage: make easily, cost is low, install easily, so far continued to use, weak point is the external application hinge always, and it is big to take up room, not attractive in appearance, outstanding shortcoming is dangerous, the pick-proof poor performance, and especially anti-forcing open the door gone up the bright hinge of installation, it is extremely inconvenient that demolition is installed, and makes troubles to building operations.

For solving the deficiency of above bright hinge, the purpose of this utility model provides a kind of row to fan the anti-direct insertion hinge of forcing open the door, and fan on the door at doorframe and row hinge both sides iron chains pincers respectively, it is a kind of Concealed hinges, solved the safety of door hinge effectively, attractive in appearance, the problem of easy installation and removal.

Structure design of the present utility model is achieved in that this row fan is anti-and forces open the door direct insertion hinge by major-minor hinge A, B two parts are formed, main hinge A (as shown in Figure 1) is the movable lug folding, be installed in the doorframe of metal construction, subsidiary hinge B (as shown in Figure 2) is the foldings of wedge trousers, in being installed in that metal is anti-and forcing open the door, two pairs are contained in respectively on doorframe and anti-the forcing open the door up and down, wherein main hinge A, movable lug folding front is a metal plate, the metal plate back is a folding basin, the folding box be fixed with axle sleeve up and down respectively, axle sleeve is fixed with rotating shaft near outward flange between the axle sleeve, be fixed with movable lug in the rotating shaft, the movable lug inner end is enclosed within the rotating shaft and with rotating shaft and fixes, the movable lug outside is that a flat board is 90 ° of angles with rotating shaft, and boundary line, movable lug outside slopes inwardly, and forms wedge shape, the depression breach is left in inboard, movable lug top, movable lug can be done more than 45 ° rotation around the shaft, and the metal plate of movable lug folding front has fixing hole up and down, with fixing folding usefulness; Subsidiary hinge B, wedge trousers folding front is a metal plate, wedge trousers are fixed in the back, the wedge trousers are a flat sleeve, and outward flange slopes inwardly, and is wedge shape, just corresponding with the movable lug wedge shape, the front of metal plate has a bar shaped notch up and down, the movable lug of main hinge stretches into from strip gab just, and the ancient festival in spring and autumn held on water banks to drink and cleanse away the evil influences trousers are stuck on the movable lug, and the strip gab upper end is dropped in the depression breach of inboard, movable lug top, closely join Chinese parasol tree, rotate with movable lug, have fixing hole on the metal plate simultaneously, to be fixed on anti-the forcing open the door.

When installing and using with two main hinge iron chains pincers on metal door frame, tight with screw because of on doorframe, two subsidiary hinge iron chains pincers are on metal is prevented forcing open the door, the same bolt of using, this moment, the movable lug with main hinge stretched into from the bar shaped notch of subsidiary hinge respectively, utilize the weight free-falling of door, make the wedge trousers hang on the movable lug to become to closely cooperate, prevent forcing open the door and to pivot.

Advantage of the present utility model: anti-forcing open the door used direct insertion hinge, and demolition is very convenient, and the pick-proof performance is good, and Concealed hinges is safe and reliable, and the space is little between door and the frame, is convenient to indoor heat insulating, is adapted at the local use of northern cold weather.

The detailed structure of the utility model is provided by following examples and accompanying drawing.

Fig. 1 is the anti-direct insertion hinge master hinge structure chart of forcing open the door of row's fan;

Fig. 2 is the anti-direct insertion hinge subsidiary hinge structure chart of forcing open the door of row's fan.

Its structure is by shown in the accompanying drawing, 1 is metal plate, on wear anchoring filament hole 11,2 and be the folding box, 3 is axle sleeve, all be welded on up and down on the folding box, 4 are rotating shaft, and two ends are all stretched in axle sleeve up and down, 5 is movable lug, one end is enclosed within the rotating shaft, is welded into one with rotating shaft, and the other end becomes 90 ° of angles and top with rotating shaft be wedge shape, can rotate around the axis, 6 are folding box side opening, and 7 for paying the hinge metal plate, has fixing hole 10 above, dull and stereotyped back is welded with wedge trousers 8, the wedge trousers can be enclosed within on the movable lug just, and dull and stereotyped 7 fronts have forward opening 9, and movable lug can insert from opening, be stuck in the wedge trousers, main hinge is fixed on the doorframe, pays hinge and is fixed on the doorframe, has realized that anti-direct insertion of forcing open the door connects.
