Abstract

The utility model relates to a hinge for a prizing-proof door, including a hinge arm, two independent fixed plates, bearings and round pins, wherein the hinge arm is arranged in the middle, two sides of the hinge arm are provided with bearings, the external side of the bearings is provided with the two independent fixed plates facing with each other, finally the round pins are inserted into an axle hole of the fixed plates, the bearings and the hinge arm to fix, such that the whole hinge is linked to integrate. When mounting, the hinge arm is fixedly connected with the bolt and the doorframe from inner to outer, the two independent fixed plates are connected fixedly with the screw and the anti-pick door from outer to inner.

Description

A kind of pick-proof door hinge

Technical field

The utility model relates to a kind of pick-proof door hinge, is adapted at installing and using on various anti-the forcing open the door.

Background technology

At present, the pick-proof door hinge is of a great variety, what comparatively generally use is rotary hinge mechanism, its structure is made up of two fans inside and outside flap and the fixed arm, hinge exterior wing and doorframe are fixedly connected, the hinge interior wing and the pick-proof couplet on the door connect, and with the rotating shaft break-through, two ends are fixed between hinge two fans again, adopt the switch of the way realization door of intermediate rotary shaft sliding friction, wherein the hinge exterior wing all adopts monomer structure and doorframe to fix, and this kind hinge advantage is simple in structure, produces easily, but its deficiency is to adopt sliding friction, life-span is short, and exterior wing adopts monomer structure, installation and maintenance inconvenience in the hinge.

Summary of the invention

For solving the deficiency of above hinge arrangement, the purpose of this utility model provides a kind of novel pick-proof door hinge, and fixed head is designed to two monomer structures, middle with the bearing connection, to reach easy to install, long service life, produce simply purpose easy to maintenance.

Structure design of the present utility model is to realize like this having: its structure of the utility model pick-proof door hinge includes hinge arms, two independent stationary plates, bearing and round pin, detailed structure is a hinge arms in the middle of being, bearing is equipped with in the hinge arms both sides, two independent stationary plates of bearing outside dress, install relatively, at last at fixed head, bearing, inserting round pin in the axis hole of hinge arms fixes, in aggregates after the whole hinge-coupled, hinge arms is from inside to outside fixedlyed connected with doorframe with bolt during installation, two independent stationary plates are fixedly connected with a chain for binding criminals nail and anti-forcing open the door respectively from outside to inside, and its structure as shown in Figure 2.

The utility model has following advantage compared with the prior art: structure is very simple, produces easily, installs and uses easy to maintenance.

1 round pin, 2 fixed heads, 3 bearings, 4 hinge arms, 5 bearings, 6 fixed heads among the figure

The specific embodiment

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

The utility model structure such as Fig. 1, shown in 2, the centre is a hinge arms 4, bearing 3 and 5 are equipped with in hinge arms 4 two ends, two

bearings

3 and 5 outer is adorned

fixed head

2 and 6 respectively, penetrates fixingly at last from axis hole with round pin 1, and whole hinge assembling is afterwards in aggregates, during use hinge arms and fixed head are separately fixed on pick-proof every frame and anti-the forcing open the door, it is convenient especially to produce, install, use.

Claims

1 one kinds of pick-proof door hinges, form by hinge arms and fixed head, it is characterized in that: this its structure of pick-proof door hinge includes hinge arms (4), two independent stationary plates (2) (6), bearing (3) (5) and round pin (1), detailed structure is a hinge arms (4) in the middle of being, bearing (3) (5) is equipped with in hinge arms (4) both sides, two independent stationary plates (2) (6) of bearing (3) (5) outside dress, install relatively, it is fixing to insert round pin (1) at last in the axis hole of fixed head (2) (6), bearing (3) (5), hinge arms (4), in aggregates after the whole hinge-coupled.
