Abstract

The utility model relates to a theft-proof hinge, which comprises two hinge plates and a connecting shaft. Mounting holes are arranged on the hinge plates, one side of the two hinge plates is respectively provided with interlaced circular cylinders with the same diameter, and the circular cylinders of the two hinge plates are overlapped together. The connecting shaft passes through the overlapped circular cylinders and fixes the two hinge plates together, and the two hinge plates can rotate corresponding to the connecting shaft. The other side of the two hinge plates is respectively provided with an inserting plate which is combined with each hinge plate as integration and is vertical to each hinge plate, and the positions of the inserting plates are crossedly arranged on the two hinge plates. The utility model has the advantages of simple structure and high theft-proof performance, and the utility model can be widely used in industries such as architecture, furniture, etc.

Description

Theft-proof hinge

The utility model relates to the connection part that a kind of door, window or wing are used, especially a kind of folding.

At present, known folding is made of two flat flaps and connecting axle, installing hole is arranged on the flap, one side of two flap has circular cylinder staggered, that diameter is identical respectively, the circular cylinder of two flap overlaps, connecting axle passes the circular cylinder that overlaps the plate of two foldings is fixed together flap connecting axle rotation relatively.This kind structure when mounted, outside the folding connecting axle often was exposed to, robber person's any ends that adopt sawed-off or filing connecting axle the whole sled of the door row robber that falls then to enter the room more.

The purpose of this utility model provide a kind of destroy connecting axle after, the Anti-stealling hinge that door can not whole sled falls.

The purpose of this utility model is achieved in that

The utility model comprises two flap and connecting axle, installing hole is arranged on the flap, one side of two flap has the identical circular cylinder of staggered diameter respectively, the circular cylinder of two flap overlaps, connecting axle passes the circular cylinder that overlaps two flap is fixed together, and flap connecting axle rotation relatively, it is characterized in that: the opposite side of two flap respectively have one with flap separately be one and perpendicular to the plate of separately flap, the The attracted numbers on two flap is staggered up and down.

The utility model is owing to adopt said structure, then closing the plate that is fixed on the flap on the door behind the door injects in the doorframe, be fixed in the plate inserting door of the flap on the doorframe, as long as door lock is good, even connecting axle is struck off, door, doorframe and folding still are in interlocking state, have fundamentally solved the problem of entering the room of forcing open the door that prevents, have reached the purpose of this utility model.The utility model is simple in structure, and theftproof performance is good, can be widely used in industries such as building, furniture.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a lateral view of the present utility model.

Fig. 3 is a vertical view of the present utility model.

Fig. 4 is closure state figure of the present utility model.

Among the figure: 1, connecting axle, 2, flap, 3, plate, 4, flap, 5, plate, 6, installing hole, 7, circular cylinder, 8, circular cylinder.

See on Fig. 1,2,3,4

flap

2,4 installing hole 6 is arranged, one side of

flap

2,4 has the identical circular cylinder of staggered

diameter

8,7 respectively, the

circular cylinder

8,7 of two

flap

2,4 overlaps, connecting axle 1 passes the

annular framework

8,7 that overlaps, two

flap

2,4 are fixed together, the opposite side of two

flap

2,4 have respectively one with flap separately be one, and it is upper and lower staggered perpendicular to

plate

3,5 positions on

plate

3,5, two flap of flap separately.

The front end of plate can be profile of tooth.(seeing shown in Fig. 2 double dot dash line) is convenient to plate and inserted in door or the doorframe, and door and doorframe have groove in the relevant position that plate enters during use.

Claims

1, a kind of Anti-stealling hinge, comprise two flap and connecting axle, installing hole is arranged on the flap, one side of two flap has the identical circular cylinder of staggered diameter respectively, the circular cylinder of two flap overlaps, connecting axle passes the circular cylinder that overlaps two flap is fixed together, and flap connecting axle rotation relatively, it is characterized in that: the opposite side of two flap respectively have one with flap separately be one and perpendicular to the plate of separately flap, the The attracted numbers on two flap is upper and lower staggered.

2, Anti-stealling hinge as claimed in claim 1 is characterized in that: the front end of plate is a profile of tooth.
