Abstract

The utility model relates to an anti-pick door large angle hinge, the structure of which belongs to a mechanical hinge. The structure of the utility model is composed of two side hinge bodies and middle arc connectors; the two side hinge bodies are arranged in parallel, the connectors comprise four groups, and every two groups are arranged alternatively; the inner sides of the connectors are fixedly connected with the hinge bodies by rotating shafts, the outsides of every two connectors which are adjacent are spaced, correspond to each other, and are connected by the rotating shafts, the centers of the four connectors are transversely penetrated with the rotating shafts in sliding slots which are arranged on the outsides of the hinge bodies, and the connectors can be moved from up to down in the sliding slots which are arranged on the outsides of the hinge bodies. The utility model has the advantages of simple structure, and convenient installation and operation; the opening angle is large because the middle parts of the utility model are connected by connectors, and the rotation of 180 DEG can be performed; the utility model is suitable for the operation of various mechanical rotating shafts.

Description

The anti-wide-angle hinge of forcing open the door

The utility model belongs to a kind of mechanical hinge, be adapted at anti-force open the door or other rotary machine on use.

At present, in building construction, the employed hinge of door and window remains common metal hinge, its structure is that both sides are fixed head, has fixing hole on the plate, is installed with rotating shaft between its two fixed head, the rotating shaft alternatively up and down is equipped with axle sleeve, and this kind hinge arrangement is simple, produces easily, its weak point is an intensity difference, and the pick-proof performance is bad, quick abrasion, life-span is short, disadvantage is that opening angle is little, only is 90 °, gives to install and use and makes troubles.

For solving above deficiency, the purpose of this utility model provides a kind of anti-wide-angle hinge of forcing open the door, and utilizes the structure of bilateral rotating shaft, to realize big, the easy to install purpose of opening angle.

The structure design of the utility model is achieved in that the wide-angle hinge is made up of both sides hinge bodies and medial arc connector, the both sides hinge bodies is that opposing parallel is placed, every side hinge bodies has fixing hole up and down, the arc connector is equipped with in the centre, connector is four groups, alternately connect in twos, every group of connector is same four stacked compositions, it is half arc (as shown in Figure 1), two groups the end of wherein being separated by is fixedly connected with the rotating shaft of hinge bodies inboard, other two a groups end is fixedly connected with rotating shaft equally with the opposite side hinge bodies, the outer end of four connectors joins in twos, and the centre is installed with fixed axis, and two fixed axis are contained in respectively in the chute in the hinge bodies outside, and can slide up and down in chute, four groups of connector central cross are installed with rotating shaft.

The advantage of the utility model: simple in structure, form by the standard mechanical parts, easy to install, because the centre is added with connector and connects with rotating shaft, so the hinge bodies opening angle is big, can 180 ° of arbitrarily angled opening, flexible movements, intensity is good, and is durable in use.

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

Fig. 1 is the anti-wide-angle hinge arrangement schematic diagram of forcing open the door.

Fig. 2 is the anti-wide-angle hinge arrangement lateral view of forcing open the door.

Its structure is that both sides 1,2 are hinge bodies, middle 3,4 is connector, connector is four group 3,4 side by side, 3a, 4a, every group is that four laminations are formed, the two groups of connectors of being separated by connect with fixed rotating shaft 5,6 with hinged component with inboard, four groups of connectors cross connection with central axis 9, the tetrad fitting outside is installed with fixed axis 7,8 in twos, and in the chute 10,11 of hinged component 1,2, axle 7,8 can slide up and down in chute 10,11, hinge bodies 1,2 can be opened arbitrarily mutually, and opening angle can be 180 °.
